Abstract
Breast cancer (BC) is the most prevalent malignancy in women globally. At time of diagnosis, premenopausal BC is considered more aggressive and harder to treat than postmenopausal cases. Cytochrome P450 (CYP) enzymes are responsible for phase I of estrogen metabolism and thus, they are prominently involved in the pathogenesis of BC. Moreover, CYP subfamily 2C and 3A play a pivotal role in the metabolism of taxane anticancer agents. To understand genetic risk factors that may have a role in pre-menopausal BC we studied the genotypic variants of CYP2C8, rs11572080 and CYP3A4, rs2740574 in female BC patients on taxane-based therapy and their association with menopausal status. Our study comprised 105 female patients with histologically proven BC on paclitaxel-therapy. They were stratified into pre-menopausal (n = 52, 49.5%) and post-menopausal (n = 53, 50.5%) groups. Genotyping was done using TaqMan assays and employed on Quantstudio 12 K flex real-time platform. Significant increased frequencies of rs11572080 heterozygous CT genotype and variant T allele were established in pre-menopausal group compared to post-menopausal group (p = 0.023, 0.01, respectively). Moreover, logistic regression analysis revealed a significant association between rs11572080 CT genotype and premenopausal BC. However, regarding rs2740574, no significant differences in genotypes and allele frequencies between both groups were detected. We reported a significant association between CYP2C8 genotypic variants and premenopausal BC risk in Egyptian females. Further studies on larger sample sizes are still needed to evaluate its importance in early prediction of BC in young women and its effect on treatment outcome.

Abstract
Breast cancer is a highly common form of cancer that impacts a considerable proportion of women on a global scale. Interleukin 17A (IL-17A) is a cytokine that has both anti-tumor and pro-tumor effects, which can vary depending on the specific tumor microenvironment. The aim of this study was to determine whether IL-17A can be used as a biomarker for diagnosis of breast cancer. Therefore, we compared concentrations of serum IL-17A in patients suffering from breast carcinoma and normal control women by an enzyme-linked immunosorbent assay (ELISA). This study included 86 women, 44 patients that were diagnosed with breast carcinoma, and 42 normal control women. Serum IL-17A levels in both case and control groups were measured by sandwich ELISA kits. The IL-17A serum level was significantly higher among patients with breast carcinoma than in the control group (p <0.001). The serum IL-17A concentration was significantly higher in estrogen receptor-positive cases than in estrogen receptor-negative cases (p=0.033). The highest levels of IL-17A were detected in patients with stage 2 breast carcinoma rather than stage 3 with no significant correlation. There was no correlation between IL-17A level and tumor size, lymph node invasion, or metastasis in patients with breast cancer. In conclusion, a high level of IL-17A in breast carcinoma patients compared to the control group was detected in our study. It indicates that IL-17A could be a promising biomarker for diagnosis of breast cancer and may play a role in tumor development. High levels of IL-17A were not a predictor of poor prognosis in breast cancer patients as it was not related to tumor size, lymph node invasion, or metastasis.

Abstract
BACKGROUND Elevated serum levels of MMP-13 are linked to tumor growth and metastasis, while miR-138 dysregulation is observed in breast cancer cases. The aim of this study is to investigate the expression of miR-138 and MMP-13 levels as potential biomarkers for the prognosis of breast cancer. PATIENTS AND METHOD In this retrospective case-control study, 119 female subjects were recruited and divided into three groups. MMP-13 level was measured using Enzyme Linked Immunosorbent Assay (ELISA), while real-time PCR technique was employed to quantify miR-138 expression. RESULTS Both non-metastatic and metastatic groups showed significantly higher levels of serum MMP-13 compared to other groups. MMP-13 levels are significantly increased among patients with advanced tumor size, lymph node metastasis, and triple-negative breast cancer cases. An inverse significant association between MMP-13 levels and response to treatment was observed. Expression of miR-138 underwent a significant down-regulation in breast cancer patients, and a statistically significant association was established between miR-138 expression and triple-negative breast cancer cases. A positive association was detected between the increase in miR-138 expression and the good response to treatment. The expression of miR-138 was inversely correlated with the MMP-13 levels. CONCLUSION MMP-13 levels were significantly higher in breast cancer, especially in advanced cases, suggesting its role in promoting tumor invasion and metastasis. MiR-138 was down-regulated in breast cancer, especially in triple-negative breast cancer patients, rendering it a promising biomarker for triple-negative breast cancer. Modulation of miR-138 expression and MMP-13 levels may represent therapeutic targets for breast cancer.

Abstract
Breast cancer, the most prevalent cancer among women, has posed a significant challenge in identifying biomarkers for early diagnosis and prognosis. This study aimed to elucidate the gene expression profile of Estrogen Receptor-1 (ESR-1), long non-coding RNA HOTAIR, and microRNA-130a in the serum of Egyptian breast cancer patients, evaluating the potential of HOTAIR and miR-130a as biomarkers for predicting pathological parameters in BC. The study involved 45 patients with primary BC, with serum samples collected preoperatively and postoperatively twice. The expression levels of ESR-1, HOTAIR, and miR-130a were quantified using real-time PCR and analyzed for correlations with each other and with the clinical and pathological parameters of the patients. Serum HOTAIR levels exhibited a strong positive association with metastasis and demonstrated a significant increase after 6 months in all patients with locally advanced and stage IV BC. Conversely, tumors with advanced stages and metastatic lesions showed significantly lower expression levels of miR-130a. Notably, a significant positive correlation was observed between preoperative ESR-1 expression and both HOTAIR and miR-130a levels. Serum HOTAIR and miR-130a levels have emerged as promising non-invasive biomarkers with the potential to predict the pathological features of BC patients. HOTAIR, an oncogenic long non-coding RNA (lncRNA), and miR-130a, a tumor suppressor miRNA, play crucial roles in tumor progression. Further investigations are warranted to elucidate the intricate interplay between HOTAIR and miR-130a and to fully comprehend the contribution of HOTAIR to BC recurrence and its potential utility in early relapse prediction.

Abstract
Objectives: Leptin and adiponectin are adipose-derived immune modulators (adipokines) that may contribute to SLE pathology and symptoms. This study aimed to evaluate the associations of serum adiponectin and leptin with clinical manifestations and disease activity in SLE patients. Methods: This is a case control study, where 70 SLE patients and 50 age- and sex-matched healthy controls were enrolled from the Rheumatology and Rehabilitation Department of Beni-Suef University Hospital from June 2020 till April 2022. The SLE disease activity index (SLEDAI) and Systemic Lupus International Collaborative clinics/America Collage of Rheumatology damage index were used to assess disease severity. Laboratory parameters including erythrocyte sedimentation rate (ESR) and serum concentrations of antinuclear antibody (ANA), anti-double stranded DNA, complement 3 and 4, lipids, and C-reactive protein (CRP) were measured and compared between SLE and control groups. Serum adiponectin and leptin were also measured by enzyme-linked immunosorbent assays (ELISA). Results: Compared to healthy controls, SLE patients exhibited significantly greater serum leptin (21.1 vs 3.9 ng/mL, p < 0.001) and adiponectin (18.1 vs 4.8 ng/mL, p < 0.001), and both values were positively correlated with SLEDAI scores (p = 0.048 and 0.042). Higher serum leptin was significantly associated with lupus nephritis (LN) (p = 0.048) as well as greater body mass index (p = 0.010), ESR (p = 0.002), serum CRP (p = 0.003), total cholesterol (p = 0.013), and uric acid (p = 0.002), while higher adiponectin was significantly associated with LN (p = 0.046). Conclusion: Serum leptin and adiponectin levels are associated with the clinical and pathological manifestations of SLE, suggesting direct involvement in disease progression and utility as diagnostic biomarkers and therapeutic targets.

Abstract
OBJECTIVES Since being declared a global pandemic, the SARS-CoV-2 virus had a significant impact on the entire globe. The pandemic has placed a heavy burden on healthcare systems worldwide, and cancer patients are particularly prone. Despite the fact that initial international reports suggest delays in breast cancer (BC) diagnosis and screening programs, the Egyptian context requires additional research on this topic. To examine whether COVID-19 has changed the pattern of disease presentation before and after the pandemic, focusing on the tumor, node, and metastasis (TNM) staging of the disease at the initial presentation. METHODS This single-center, retrospective study of female BC patients initially diagnosed at Baheya Foundation was conducted during the following time frames: from Jan 2019 to Jan 2020 (Pre COVID-19 cohort) and from Mar 2020 to Mar 2021 (post-COVID-19 cohort). We compared the two cohorts in terms of clinical characteristics, tumor characteristics, and the number of days from presentation to treatment. Our primary endpoint was the difference in the TNM stage of BC at the initial presentation. RESULTS This analysis included 710 BC patients, 350 from the pre-COVID cohort and 360 from the post-COVID group. We detected a 27.9% increase in late-stage BC (stages III-IV) in the post-pandemic cohort compared to the pre-pandemic (60.1% vs. 47%, p < 0.001). The time from diagnosis to commencement of treatment was significantly longer (28.34 ± 18.845 vs 36.04 ± 23.641 days, p < 0.001) in the post-COVID cohort (mean difference = 7.702, 95% CI 4.54-10.85, p < 0.001). A higher percentage of patients in the post-pandemic cohort received systemic neoadjuvant therapy (p-value for Exact's test for all treatment options = 0.001). CONCLUSIONS The number of patients requiring systemic neoadjuvant chemotherapy increased dramatically in the post-pandemic group with advanced stages of BC at presentation. This study highlights the need for proper management of cancer patients during any future pandemic.

Abstract
BACKGROUND Breast cancer (BC) is the most often diagnosed cancer in women globally. Cancer cells appear to rely heavily on RNA helicases. DDX43 is one of DEAD- box RNA helicase family members. But, the relationship between clinicopathological, prognostic significance in different BC subtypes and DDX43 expression remains unclear. Therefore, the purpose of this study was to assess the clinicopathological significance of DDX43 protein and mRNA expression in different BC subtypes. MATERIALS AND METHODS A total of 80 females newly diagnosed with BC and 20 control females that were age-matched were recruited for this study. DDX43 protein levels were measured by ELISA technique. We used a real-time polymerase chain reaction quantification (real-time PCR) to measure the levels of DDX43 mRNA expression. Levels of DDX43 protein and mRNA expression within BC patients had been compared to those of control subjects and correlated with clinicopathological data. RESULTS The mean normalized serum levels of DDX43 protein were slightly higher in control than in both benign and malignant groups, but this result was non-significant. The mean normalized level of DDX43 mRNA expression was higher in the control than in both benign and malignant cases, although the results were not statistically significant and marginally significant, respectively. Moreover, the mean normalized level of DDX43 mRNA expression was significantly higher in benign than in malignant cases. In malignant cases, low DDX43 protein expression was linked to higher nuclear grade and invasive duct carcinoma (IDC), whereas high mRNA expression was linked to the aggressive types of breast cancer such as TNBC, higher tumor and nuclear grades. CONCLUSION This study explored the potential of using blood DDX43 mRNA expression or protein levels, or both in clinical settings as a marker of disease progression in human breast cancer. DDX43 mRNA expression proposes a less invasive method for discriminating benign from malignant BC.

Abstract
BACKGROUND This study aimed to determine the prevalence of HCV and occult HBV among newly diagnosed pre-treatment Egyptian lymphoma patients and evaluate patients' outcomes based on the presence of the viral infections. METHODS The study included 80 therapy-naïve lymphoma patients including 71 non-Hodgkin lymphoma (NHL) and 9 Hodgkin lymphoma disease (HD) in addition to 100 healthy volunteers. HBV screening using HBsAg and anti-HBc IgM and HCV using AB/Ag ELISA and real-time RT-PCR were screened in tested and control groups. The diagnosis was confirmed by histopathology. Overall survival (OS) and progression-free survival (PFS) were conducted to diseased patients. RESULTS Healthy patients showed 4/100, (4%) active HCV infection and 1/100, (1%) active HBV infection and no occult HBV infection. Among NHL patients, 28 were positive for HBV (6 active and 22 occult HBV infection). Occult HBV was also detected in 5/9 HD patients. HCV was detected in (30/71, 42.3%) of NHL patients and in a single HD patient. Ten occult HBV NHL patients showed a mixed infection with HCV. The incidence of both HCV and HBV are higher in NHL than HL patients. After antitumor treatment, complete remission for lymphoma was achieved in 45% of patients. Both overall survival (OS) and progression-free survival (PFS) were correlated and significantly associated with patients' LDH levels. CONCLUSIONS Our findings claim the suggestive role of HCV and occult HBV infections in NHL but not HL patients in comparison to healthy control, suggesting pre-screening of related factors including occult HBV in for potential better therapy response.

Abstract
BACKGROUND Toll-like receptors (TLRs) play an important role in regulation of immune cells and are vital in tumorigenesis due to its crucial role in inflammatory microenvironment regulation, as they promote the synthesis and release of inflammatory cytokines and chemokines. Toll-like receptors 4 and TLRs 9 were found to be highly expressed in breast cancer. The aim of this study is to investigate the soluble toll-like receptors 4 and 9 (sTLR4 and sTLR9) as potential biomarkers for diagnosis and prognosis of breast cancer and their association with the clinicopathological parameters of breast cancer. PATIENTS AND METHOD In this retrospective case-control study, 186 female subjects were recruited and divided into three groups, Group I: 62 healthy control, Group II: 62 subjects diagnosed with non-metastatic breast cancer, and Group III: 62 subjects diagnosed with metastatic breast cancer. Enzyme-linked immunosorbent assay (ELISA) technique was used to quantify the levels of sTLR4 and sTLR9 in serum. RESULTS Both non-metastatic and metastatic groups showed significant higher levels of both serum sTLR4 and sTLR9 expression compared to healthy controls. Only sTLR9 was significantly increased among metastatic patients compared to non-metastatic group. Serum levels of sTLR9 and sTLR4 were still significantly associated with breast cancer in a multiple logistic regression model (P = <.001). ROC curves showed that both sTLR4 and sTLR9 can be a significant parameter to discriminate between normal females and breast cancer patients. CONCLUSION Soluble toll-like receptors 4 and sTLR9 are over-expressed in patients with metastatic and non-metastatic BC than in benign cases. The expression levels of sTLR4 and TLR9 have clinical interest as indicators of tumor aggressiveness suggested to be prognostic biomarkers. Toll-like receptors may represent therapeutic targets in breast cancer.

Abstract
BACKGROUND Precision oncology has been increasingly used in clinical practice and rapidly evolving in the oncology field. Thus, this study was performed to assess the frequency of germline mutations in early and late onset familial breast cancer (BC) Egyptian patients using multi-gene panel sequencing to better understand the contribution of the inherited germline mutations in BC predisposition. Moreover, to determine the actionable deleterious mutations associated with familial BC that might be used as biomarker for early cancer detection. METHODS Whole blood samples were collected from 101 Egyptian patients selected for BC family history, in addition to 50 age-matched healthy controls. A QIAseq targeted DNA panel (human BC panel) was used to assess the frequency of germline mutations. RESULTS A total of 58 patients (57.4%) out of 101 were found to have 27 deleterious germline mutations in 11 cancer susceptibility genes. Of them, 32 (31.6%) patients carried more than one pathogenic mutation and each one carried at least one pathogenic mutation. The major genes harboring the pathogenic mutations were: ATM, BRCA2, BRCA1, VHL, MSH6, APC, CHEK2, MSH2, MEN1, PALB2, and MUTYH. Thirty-one patients (30.6%) had BRCA2 mutations and twenty (19.8%) had BRCA1 mutations. Our results showed that exon 10 and exon 11 harbored 3 and 5 mutations, respectively, in BRCA1 and BRCA2 genes. Our analysis also revealed that the VHL gene significantly co-occurred with each of the BRCA2 gene (p = 0.003, event ratio 11/21), the MSH2 gene (p = 0.01, 4/10), the CHEK2 gene (p = 0.02, 4/11), and the MSH6 gene (p = 0.04, 4/12). In addition, the APC gene significantly co-occurred with the MSH2 gene (p = 0.01, 3/7). Furthermore, there was a significant mutually exclusive event between the APC gene and the ATM gene (p = 0.04, 1/36). Interestingly, we identified population specific germline mutations in genes showing potentials for targeted therapy to meet the need for incorporating precision oncology into clinical practice. For example, the mutations identified in the ATM, APC, and MSH2 genes. CONCLUSIONS Multi-gene panel sequencing was used to detect the deleterious mutations associated with familial BC, which in turns mitigate the essential need for implementing next generation sequencing technologies in precision oncology to identify cancer predisposing genes. Moreover, identifying DNA repair gene mutations, with focus on non-BRCA genes, might serve as candidates for targeted therapy and will be increasingly used in precision oncology.

Abstract
Abstract
Objective
Breast cancer (BC) is one of the most commonly diagnosed solid malignancies in women worldwide.
Purpose
Finding new non-invasive circulating diagnostic biomarkers will facilitate the early prediction of BC and provide valuable insight into disease progression and response to therapy using a safe and more accessible approach available every inspection time. Therefore, our present study aimed to investigate expression patterns of potentially circulating biomarkers that can differentiate well between benign, malignant, and healthy subjects.
Methods
To achieve our target, quantitative analyses were performed for some circulating biomarkers which have a role in the proliferation and tumor growth, as well as, glutamic acid, and human epidermal growth receptor 2 (HER2) in blood samples of BC patients in comparison to healthy controls using qRT-PCR, liquid chromatography/mass spectrometry (LC/MS/MS), and ELISA.
Results
Our findings showed that the two miRNAs (miRNA-145, miRNA-382) were expressed at lower levels in BC sera than healthy control group, while miRNA-21 was expressed at higher levels in BC patients than control subjects. Area under ROC curves of BC samples revealed that AUC of miRNA-145, miRNA-382, miRNA-21, and glutamic acid was evaluated to equal 0.99, 1.00, 1.00 and 1.00, respectively. Besides, there was a significantly positive correlation between miRNA-145 and miRNA-382 (r = 0.737), and a highly significant positive correlation between miRNA-21 and glutamic acid (r = 0.385).
Conclusion
Based on our results, we conclude that the detection of serum miRNA-145, -382 and -21 as a panel along with glutamic acid, and circulating HER2 concentrations could be useful as a non-invasive diagnostic profiling for early prediction of breast cancer in Egyptian patients. It can provide an insight into disease progression, discriminate between malignancy and healthy control, and overcome the use limitations (low sensitivity and specificity, repeated risky exposure, and high cost) of other detecting tools, including mammography, magnetic resonance imaging, and ultrasound.

Abstract
Coronavirus disease 2019 (COVID-19) has affected millions of people worldwide. During the early stages of vaccination in Egypt, the ChAdOx1 nCoV-19 and BBIBP-CorV vaccines were the most distributed. The aim of this study was to compare the immune responses and short-term efficacies of these two vaccines. We recruited adults who received two doses of either vaccine. Samples were collected after the first dose of ChAdOx1 nCoV-1 and after the second dose of both vaccines. Antibodies against SARS-CoV-2 antigens were measured using LABScreen™ COVID Plus kits, and cell-mediated immune responses were assessed using flow cytometry. Of the 109 recruited subjects, 60 (55%) received the ChAdOx1 nCoV-19 vaccine, and the remainder received the BBIBP-CorV vaccine. The total antibody level did not significantly differ between the two groups. The level of the anti-spike subunit 2 (S2) antibody was significantly higher in the ChAdOx1 nCoV-19 group. The percentages of both total T cells and B cells were unaffected by the type of vaccination. However, the ChAdOx1 nCoV-1 vaccine was significantly associated with a higher percentage of CD8+ cells. The vaccines did not significantly differ in the number or severity of infections postvaccination. None of the participants were admitted to the hospital or died of COVID-19 infection. In conclusion, the BBIBP-CorV vaccine is associated with an immune response and protection against infection that is comparable to that of the ChAdOx1 nCoV-1 vaccine. Follow-up is needed to study the long-term protective effects of both vaccines. Inactivated vaccines are easier to manufacture in developing countries and their limited side effects may lead to better economic benefits by limiting the number of absences from work.

Abstract
The aim of this study was to assess the effect of two types of stressors,
regarding the extent of involvement of ouabain (OUA), hippocampal
sodium/potassium ATPase (NKA) expression, and the hippocampal
corticosterone receptors (CR)/melatonin receptors
(MR) expression ratio, on the behavioral and cardiovascular
responses and on the hippocampal cornu ammonis zone 3 (CA3) and dentate gyrus
(DG). Thirty adult male Wistar albino rats aged 7-8 months were exposed to
either chronic immobilization or a disturbed dark/light cycle and treated with
either ouabain or vehicle. In the immobilized group, in the absence of
hippocampal corticosterone (CORT) changes, rats were non-responsive to stress,
despite experiencing increased pulse rate, downregulated hippocampal
sodium/potassium pump, and enhanced hippocampal CR/MR
expression ratio. Prolonged darkness precipitated a reduced upright attack
posture, with elevated CORT against hippocampal MR
downregulation. Both immobilization and, to a lesser extent, prolonged darkness
stress resulted in histopathological and ultrastructural neurodegenerative
changes in the hippocampus. OUA administration did not change the behavioral
resilience in restrained rats, despite persistence of the underlying biochemical
derangements, added to decreased CORT. On the contrary, with exposure to short
photoperiods, OUA reverted the behavior towards a combative reduction of
inactivity, with unvaried CR/MR and CORT, while ameliorating
hippocampal neuro-regeneration, with co-existing NKA and
MR repressions. Therefore, the extent of OUA, hippocampal
NKA expression, and CR/MR expression, and
subsequent behavioral and cardiac responses and hippocampal histopathology,
differ according to the type of stressor, whether immobilization or prolonged
darkness.

Abstract
BACKGROUND The prognostic significance of cytokine receptor-like factor 2 (CRLF2) overexpression in pediatric B-cell precursor (BCP) acute lymphoblastic leukemia (ALL) is still controversial. We aimed to investigate the role of CRLF2 overexpression and JAK2 mutation in the diagnosis and prognosis of newly diagnosed pediatric B-ALL patients. METHODS CRLF2 expression was assessed by real-time quantitative polymerase chain reaction (PCR) in 115 pediatric patients newly diagnosed with precursor B-ALL patients compared with 24 age- and sex-matched controls. JAK2 R683G mutation status was performed by the qBiomarker Somatic Mutation PCR Assay. RESULTS CRLF2 overexpression was identified in 21 patients (18.3%), while the JAK2 R683G mutant type was found in only in 7 patients (6.1%). There was a significant CRLF2 overexpression in patients with high initial TLC, high blast count in blood, and organomegaly (P .04, 0.005 & 0.05 respectively). No patients with CRLF2 overexpression expressed any recurrent cytogenetic translocations. 4 patients with CRLF2 overexpression showed JAK2 R683G mutation. CRLF2 levels and JAK2 R683G mutation status did not have a significant impact on either overall survival or disease-free survival. CONCLUSION CRLF2 expression was significantly higher in Egyptian precursor B-ALL pediatric patients. CRLF2 overexpression was associated with a number of unfavorable prognostic factors with high tumor load, but was not an adverse independent parameter in pediatric BCP-ALL patients. Some patients with CRLF2 overexpression display JAK2 mutation, which may benefit from targeted therapy by kinase inhibitors.

Abstract
Genetic differences among individuals could affect the clinical presentations and outcomes of COVID-19. Human Leukocyte Antigens are associated with COVID-19 susceptibility, severity, and prognosis. This study aimed to identify HLA-B and -C genotypes among 69 Egyptian patients with COVID-19 and correlate them with disease outcomes and other clinical and laboratory data. HLA-B and -C typing was performed using Luminex-based HLA typing kits. Forty patients (58%) had severe COVID-19; 55% of these patients died, without reported mortality in the moderate group. The alleles associated with severe COVID-19 were HLA-B*41, -B*42, -C*16, and -C*17, whereas HLA-B*15, -C*7, and -C*12 were significantly associated with protection against mortality. Regression analysis showed that HLA-B*15 was the only allele associated with predicted protection against mortality, where the likelihood of survival increased with HLA-B*15 (P < 0.001). Patient survival was less likely to occur with higher total leukocytic count, ferritin, and creatinine levels. This study provides interesting insights into the association between HLA class I alleles and protection from or severity of COVID-19 through immune response modulation. This is the first study to investigate this relationship in Egyptian patients. More studies are needed to understand how HLA class I alleles interact and affect Cytotoxic T lymphocytes and natural killer cell function.

Abstract
BACKGROUND Hepatocellular carcinoma (HCC) is known to be the second leading cause of cancer-related mortality worldwide. For improving the prognosis as well as reducing the rate of mortality, early diagnosis of HCC is a must. AIMS This study was conducted to assess the ability of the serum expression of exosomal miR-18a and miR-222 to differentiate and diagnose patients with HCC, patients with liver cirrhosis, and healthy controls. METHODS This study included 51 patients with liver cirrhosis, 51 patients with HCC on top of hepatitis C virus (HCV) infection, and 50 healthy controls. RESULTS miR-18a and miR-222 were assessed using reverse transcription-polymerase chain reaction. MiR-18a and miR-222 levels were significantly higher in the liver cirrhosis and HCC groups than the control group (p ˂ 0.001). However, no statistically significant difference was found between patients with HCC and liver cirrhosis (p = 0.4 for miR-18a and p = 0.1 for miR-222). ROC curve analyses to evaluate the diagnostic performances of the two miRNAs as important noninvasive diagnostic markers revealed a best cutoff value of 2 for miR-18a to differentiate between liver cirrhosis, HCC, and healthy controls. And for mir-222, a cutoff value of 1.7 and 1.9 showed the highest specificity for discrimination between liver cirrhosis, HCC, and healthy controls, respectively. Moreover, logistic regression model revealed that miR-18a expression was independent predictive factor in HCC patients (p = 0.004), while miR-222 expression was independent predictive factor in liver cirrhosis patients (p < 0.001). CONCLUSION miR-18a and miR-222 were significantly discriminative markers between patients with liver cirrhosis and HCC and healthy individuals. Therefore, they have a prognostic rather than a diagnostic value. Moreover, miR-18a and miR-222 could be useful in identifying liver injuries, including fibrosis and cirrhosis.

Abstract
The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic resulted in more than five hundred million infected cases worldwide. The current study aimed to screen the correlation of different laboratory findings with disease severity and clinical outcomes of coronavirus disease (COVID-19) among Egyptian patients to obtain prognostic indicators of disease severity and outcome. A total of 112 laboratory-confirmed COVID-19 patients were examined. According to the severity of the disease, these patients were divided into three main groups: mild, moderate and severe cases. In addition, clinical characteristics and laboratory findings, including Hb, platelet count, white blood cell count, lymphocyte percentage, neutrophil percentage, neutrophil lymphocyte ratio (NLR), D-dimer, highly sensitive C-reactive protein (HS-CRP), alanine aminotransferase (ALT), lactate dehydrogenase (LDH) and creatinine, were measured. The presence of hypertension and/or diabetes was found to be a significant risk factor for disease severity and poor outcome. Increased respiratory rate, levels of SpO2, HS-CRP, D-dimer, NLR, ALT, LDH, lymphopenia and neutrophilia, as well as changes in chest computed tomography (CT), were associated with increased disease severity and fatal consequences. Highly sensitive C-reactive protein, D-dimer, NLR and LDH constituted excellent predictors for both disease severity and death. Laboratory biomarkers, such as HS-CRP, D-dimer, NLR and LDH, are excellent predictors for both disease severity and death. They can predict mortality in patients at the time of admission secondary to SARS-CoV-2 infection and can help physicians identify high-risk patients before clinical deterioration.

Abstract
The levels of messenger RNA (mRNA) transcription of FOXP3, IFN-γ, TNF, IL-6 and COX-2 from both COVID-19 infected and control subjects were evaluated using SYBRTM green real-time polymerase chain reaction (RT-PCR). Severe/critical cases showed significantly lower lymphocyte counts and higher neutrophil counts than the mild or moderate cases. There were significantly lower levels of mRNA expressions of IFN-γ, TNFα and FOXP3 in COVID-19 patients than in the control group. On the other hand, IL-6 and COX-2 expressions were significantly higher in patients suffering from severe disease. FOXP3 expressions were correlated with the severities of hypoxia and were excellent in predicting the disease severity. This was followed by the IL-6, COX-2 and TNFα expressions. FOXP3 expression was the only biomarker to show a significant correlation with patient mortality. It was concluded that SARS-CoV-2 infection is associated with the downregulation of FOXP3 and upregulations of IL-6 and COX-2.

Abstract
Despite the link between HCV and malignant lymphoproliferative disorders has been established, the association between occult hepatitis C virus infection and malignant lymphoproliferative disorders remains obscure. The present study intended to identify the possible association between occult HCV infection and malignant lymphoproliferative disorders. Newly diagnosed patients with LPDs were screened for the presence of HCV-RNA in both plasma and PBMCs. PBMCs of the subjects were also, examined by transmission and immuno-electron microscopy. LPD patients showed a high percentage of HCV infection (71.9%): OCI-HCV (37.5%) and HCV (34.38%). Meanwhile, 28.13% of LPD patients did not show any evidence of HCV infection. Ultrastructural examination of PBMCs revealed the presence of intracytoplasmic vacuoles enclosing viral like particles, which were less prominent in occult HCV patients. The possibility of occult HCV should be considered in patients with LPDs which can be helpful in the management of the treatment protocol in order to set up a balance between the control of the tumor progression and minimizing post chemotherapy complications related to HCV infection.

Abstract
This study monitored the changes in the expression of inflammatory IL-6 and IL-1β during the treatment period of Fluoropyrimidine (FP) based therapy. RNA was extracted from the peripheral blood of 102 CRC patients before treatment with FP therapy, and from 48 and 32 patients after 3 and 6 months of treatment, respectively. The genetic transcription of IL-6 and IL-1β was determined by real time PCR. Patients were stratified according to their levels of IL-6 and IL-1β genes expression for subgroup and survival analyses. Baseline CRC patients showed overexpression of IL-6 and IL-1β compared to healthy control. FP therapy significantly induced IL-6 and IL-1β expression. Subgroup analysis showed that patients with right colon tumors had significant elevation in both IL-6 and IL-1β with FP therapy. FP therapy significantly induced IL-1β expression in patients ⩽45 years, smokers, with high baseline level of CA19.9, right colon tumors, low grade pathology, T3 tumors and positive lymph nodes. Survival analysis showed that baseline levels of interleukins expression had insignificant effect on overall survival and event free survival. FP therapy has an impact on the level of interleukins expression declared in certain clinicopathological subgroups of CRC patients, but without a prognostic significance on patients' survival.

Abstract
BACKGROUND Multiple Myeloma (MM) is a complex hematologic malignancy, driven by several genetic and epigenetic alterations. MiRNAs as biomarkers have become a rapidly growing research area in the last decade. AIM The aim was to study the expression pattern of selected miRNAs and to explore the impact of cytogenetic aberrations in MM patients for therapeutic tools. PATIENTS AND METHODS Forty Egyptian adult patients were selected for the study with symptomatic newly diagnosed MM disease. Bone marrow samples were collected to investigate twelve miRNAs selected according to their relation to the most common cytogenetic aberrations with relevant prognostic value. The relative expression of the selected miRNAs was determined using a real-time PCR technique. Fluorescence In Situ Hybridization (FISH) technique was performed for cytogenetic analysis. RESULTS Eight miRNAs were down-regulated [miR-15a (p<0.001), miR214-3p (p<0.001), miR135b (p<0.001), miR19a-3p (p<0.001), miR19b-3p ((p=0.026), miR30e-5p (NS), miR133a (NS), miR146a- 5p (p<0.001)]. Four miRNAs were up-regulated [miR99b-5p (p=0.028), miR125a-3p (p=0.004), let7b- 5p (p<0.001), let7c-5p (p<0.001)]. Significant relation was observed between positive 14q32 rearrangement using the break apart re-arrangement probe for 14q32.33 locus and lower expression levels of miR15a (p= 0.014), 214-3p (p=0.046), 99b-5p (p=0.014), 146a-5p (p=0.041). A higher expression level of miR30e-5p was significantly related to positive 14q32 rearrangement. CONCLUSION Deregulated miRNAs were identified and the association with 14q32 rearrangement and MM pathogenesis has been determined.

Abstract
BACKGROUND Heat shock protein 70 (HSP70) is a significant cellular stress response protein that has intrinsic and extrinsic pathways to protect cells against apoptosis. It is one of the most induced proteins in cancer cells. The aim of the present study is to investigate the significant role of the HSP70 expression in Egyptian patients with breast cancer (BC) and its potential to be as a diagnostic and prognostic marker. MATERIALS AND METHODS HSP70 was examined in 155 cases in this prospective study; patients were subdivided into 3 groups: 60 patients with malignant metastatic disease, 60 patients with malignant non-metastatic disease, and 35 patients with benign lesions as control. HSP70 expression was detected using enzyme-linked immunosorbent assay (ELISA) and immunohistochemistry (IHC). RESULTS Most cases of breast cancer expressed HSP70 in both serum (98.3%) and tumor tissue (90%). A strong positive correlation was found between HSP70 IHC and ELISA (r = 0.811). The mean HSP70 levels, as detected in both patients' serum by ELISA and tumor tissue by IHC, was significantly higher in patients with BC than in benign cases (P = .001). HSP70 was significantly higher in patients with metastatic BC than in those with non-metastatic BC (P = .001). HSP70 showed positive correlation with tumor size (pT stage) and number of lymph node metastases (P ≤ .001). CONCLUSION HSP70 is over-expressed in patients with metastatic and non-metastatic BC than in benign cases. A high level of HSP70 either in patient's serum or in tumor tissue correlated significantly with advanced disease in patients with BC. This present study suggests that HSP70 can serve as a BC biomarker for early screening, diagnosis, and follow-up.

Abstract
Herein, novel green/facile approach to synthesize spongy defective zinc oxide nanoparticles (ZnONPs) is presented using for the first time pomegranate seeds molasses as a green capping fuel/reducing mediator during an aqueous solution combustion process. The developed ZnONPs is characterized by UV-Vis. Spectrophotometry and fluorimetry, XRD, Raman spectroscopy, SEM, TEM and BET. Interestingly, pomegranate seeds molasses within a viable content of bio-capping molecules reveal a defective nanoporous ZnO NPs of smaller particle size, greater pore size/volume, and higher surface area compared to the bulky non-biogenic ZnONPs. Moreover, the biosynthesized defective ZnONPs showed narrowed band gap and higher absorption of visible photons that breed higher density of hydroxyl radicals (•OH) under Solar-illumination. Even further, the bulk ZnO and the biosynthesized ZnO photocatalysts were examined in photodegrading flumequine (FL) antibiotic. The bulk ZnO gives 41.46% photodegradation efficiency compared to 97.6% for the biosynthesized ZnO. In highly acidic or highly alkaline media, FL photodegradability is greatly retarded. Scavenging experiment infers considerable contribution of holes over electrons in photodegradation reaction. The biosynthesized ZnO shows high durability in FL photodegradation after four reusing cycles. These promising findings highlight new insights for biogenic synthesis of tuned size/controlled morphology semiconductor NPs relevant to environmental remediation applications.

Abstract
BACKGROUND Repeated blood transfusions can result in the production of alloantibodies against one or more red blood cell (RBC) antigens, which can complicate future transfusions. AIM This study aims to determine the frequency and specificities of RBC alloantibodies in multitransfused adult cancer patients admitted at the National Cancer Institute, Cairo University. METHODS This cohort study enrolled 2000 multitransfused cancer patients diagnosed with different types of malignancies; they were screened for RBC alloantibodies using Serascan Diana 3 and Identisera Diana 11-cell identification panels (Diagnostic Grifols, Spain). RESULTS Of the 2000 patients tested, 25 had autoantibodies and were excluded from the study. Of the remaining 1975 patients, 181 patients had a total of 267 different alloantibodies (9.16%), with some having more than 1 antibody detected. Our study showed that more female patients (63%) than male patients (37%) had acquired RBC alloantibodies, and a higher prevalence of alloantibodies in patients with nonhematological malignancies (14%) compared with those with hematological malignancies (6.5%). The highest percentage of alloantibodies belongs to the Rh blood group system, followed by the Kell system, then Duffy, MNS, Kidd, and Lewis. Patients who received combined chemotherapy and immunotherapy exhibited a lesser antibody response compared to other patients. CONCLUSION The prevalence of alloimmunization in our study is comparable to previous reports on oncology patients. Repeated blood transfusions, which can lead to alloimmunization, often complicate future transfusions. Therefore, we recommend extending phenotype matching for patients who are presumed to depend on blood transfusions in the long term.

Abstract
Seasonal influenza viruses constitute a major global concern. Currently, H3N2 and H1N1pdm09 are the commonly circulating influenza A viruses. The haemagglutin and neuraminidase genes of influenza A(H3N2) and A(H1N1)pdm09 viruses from Egyptian paediatric patients with respiratory distress were sequenced. Mutational analysis of all published sequences from Egypt was evolutionary tracked for both HA and NA genes. Phylogenetic analysis of H3N2 HA showed that the Egyptian strains belong to 3C2 subclade while Egyptian A(H1N1)pdm09 strains belong to 6B1 subclade. Some Egyptian A(H1N1)pdm09, 2013–2014, strains form a new subclade; 6B3. High score of mutations were recorded in HA of H1N1pdm09 but higher was recorded in H3N2 strains. These findings confirmed a high mutation rate of influenza A subtypes specially H3N2 strains.

Abstract
Cu2O/CuO nano-architectures were prepared by biogenic-mediated synthesis using pomegranate seeds extract as the reducing/stabilizing mediator during an aqueous solution combustion process of the Cu2+ precursor. The fabricated Cu2O/CuO nanocomposite were characterized by X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), X-ray photoelectron spectroscopy (XPS), field emission scanning electron microscopy (FESEM) and nitrogen sorption. Nitrobenzene (NB) was applied a probe to test the catalytic activities of the fabricated Cu2O/CuO nanocomposite. The results indicated that pomegranate seeds extract (PSE) manifest Cu2O/CuO NPs of tiny particle size, larger pore volume and greater surface area compared to the bulky CuO synthesized in the absence of PSE. The surface area and total pore volume of Cu2O/CuO NPs were 20.1 m2 g−1 and 0.0362 cm3 g−1, respectively. The FESEM image shows the formation of broccoli-like architecture. The fabricated Cu2O/CuO nanocomposite possesses surprising activity towards the reduction of nitro compounds in the presence of NaBH4 into amino compounds with high conversion (94%). The reduction process was performed in water as a green solvent. Over four consecutive cycles the resulting nanocomposite also exhibits outstanding stability. In addition, the resulting Cu2O/CuO nanocomposite suggested herein may encourage scientists to start preparing more cost-effective catalysts for marketing instead of complicated catalysts.

Abstract
BACKGROUND Wilms Tumor 1 (WT1) and Survivin genes are important leukemia-associated antigens (LAAs) in AML with potential prognostic impact. METHODS We investigated WT1 and Survivin expression levels by RT-PCR in 61 AML patients in correlation with clinical characteristics and outcomes. RESULTS WT1 was overexpressed in 45 patients (73.8%), associated with higher BM blasts (p = 0.017), lower incidence of favorable-prognosis cytogenetics (p = 0.035), and higher incidence of Flt3-ITD mutations (p = 0.026). Survivin was overexpressed in 17 patients (27.9%) with higher mean WBC count (p = 0.049). Patients with overexpression of either gene showed inferior complete remission (CR) rates and survival rates, patients with overexpression of both genes showed higher mean WBCs (p = 0.035) and higher BM blasts (p = 0.029) while the double negative group showed higher incidence of favorable cytogenetic events (p = 0.021), better CR rates and survival rates. CONCLUSIONS Our findings support the introduced prognostic impact of WT1 and Survivin genes in AML patients and its potential use in MRD monitoring and immunotherapy.

Abstract
AIM Molecular characterization of the CD133+ stem cells associated with hepatocarinogensis through identifying the expression patterns of specific microRNAs (miRNAs). METHODS We investigated the expression pattern of 13 miRNAs in purified CD133+ cells separated from the peripheral blood of healthy volunteers, chronic hepatitis C (CHC), liver cirrhosis (LC) and hepatocellular carcinoma (HCC) patients a long with bone marrow samples from the healthy volunteers and the LC patients using custom miScript miRNA PCR array. RESULTS The differential expression of the 13 studied miRNAs in CD133+ cells separated from the HCC patients' peripheral blood compared to the controls revealed that miR-602, miR-181b, miR-101, miR-122, miR-192, miR-125a-5p, and miR-221 were significantly up regulated (fold change = 1.8, 1.7, 2, 5.4, 1.6, 2.9 & 1.5 P value = 0.039, 0.0019, 0.0013, 0.0370, 00024, 0.000044 &0.000007 respectively). As for the HCC group compared to the CHC group; miR-602, miR-122, miR-181b, miR-125a-5p, and miR-192 were significantly up regulated (fold change = 13, 3.1, 2.8, 1.6 & 1.56, P value = 0.01, 0.001, 0.000004, 0.002 & 0.007 respectively). Upon comparing the HCC group to the LC group; miR-199a-3p, miR-192, miR-122, miR-181b, miR-224, miR-125a-5p, and miR-885-5p were significantly up regulated (fold change = 5, 6.7, 2.3, 3, 2.5, 4.2 & 39.5 P value = 0.001025, 0.000024, 0.000472, 0.000278, 0.000004, 0.000075 & 0.0000001 respectively) whereas miR-22 was significantly down regulated (fold change = 0.57 P value = 0.00002). Only, miR-192, miR-122, miR-181b and miR-125a-5p were significant common miRNAs in CD133+ cells of the HCC group compared to the other non-malignant groups. CONCLUSION We identified a miRNA panel comprised of four miRNAs (miR-192, miR-122, miR-181b and miR-125a-5p) that may serve as a molecular tool for characterization of the CD133+ cells associated with different stages of hepatocarinogensis. This panel may aid in developing a new target therapy specific for those CD133+ cells.

Abstract
Human respiratory syncytial virus causes severe lower respiratory tract infection in neonates and children. Genotype ON1, with duplication of 72-nt in the G gene, was first detected in Canada and then recorded in other countries. In the current study, we describe the first detection of the ON1 genotype among children in Egypt in 2014/2015. Sequence analysis of the full-attachment G gene revealed that the majority of the strains examined were related to the ON1 genotype and only one sample related to N1 genotype. The Egyptian ON1 strains showed unique non-silent mutations in addition to variable mutations near the antigenic sites in comparison to the original ON1 ancestor strain. Continuous surveillance of hRSV regionally and globally is needed to understand the evolutionary mechanisms and strategies adopted by hRSV and their inducers for better adaption to the host.

Abstract
Background and Aim Hepatic ischemia reperfusion injury is the main cause of liver failure following liver surgery, so an effective method is needed to prevent or reduce this hepatic injury. The aim of the present study is to investigate the potential effect of ischemic preconditioning versus pharmacological preconditioning with lisinopril or verapamil for protection against hepatic ischemia reperfusion injury induced in rats. Methods Rats were divided into six groups. Group I served as control untreated. Rats of group II were subjected to laparotomy without induction of ischemia reperfusion. Ischemia reperfusion by ligation of the portal trait for 30 min, followed by reperfusion for 2 h, was performed in rats of groups III-VI. Ischemic preconditioning was performed for rats of group IV before induction of ischemia reperfusion. Lisinopril and verapamil was given daily for 3 days before induction of ischemia reperfusion in groups V and VI, respectively. Serum level of liver transaminases and liver malondialdehyde content were measured, and hepatic histopathological examination was assessed. Results Induction of ischemia reperfusion resulted in significant elevation of liver transaminases and liver malondialdehyde content associated with significant hepatic histopathological injury that were significantly improved by ischemic preconditioning, lisinopril, or verapamil treatment. Verapamil showed the most significant improvement compared with ischemic preconditioning or lisinopril treatment. Conclusion Ischemic preconditioning and pharmacological preconditioning by lisinopril or verapamil can protect against hepatic ischemia reperfusion probably through inhibition of oxidative stress and neutrophil infiltration. The most potent protection is demonstrated by verapamil treatment.

Abstract
BACKGROUND Identification of prognostic factors in acute lymphoblastic leukemia (ALL) patients is important for stratifying patients into risk groups and tailoring treatment accordingly. Molecular and cytogenetic abnormalities are the most important prognostic factors. Minimal residual disease (MRD) is also an important predictor of relapse in ALL. However, the correlation of both prognostic variables has not been thoroughly studied. METHODS We investigated the correlation between defined cytogenetic abnormalities and selected new MRD markers (CD79b, CD123, and CD200) in 56 newly diagnosed Egyptian pediatric B-cell ALL patients. RESULTS CD123 found to be expressed in 45% of patients, CD200 in 80.3%, and CD79b in 67.9%. MRD analysis during treatment showed stable expression patterns of CD200. There was significant association of CD123 expression with the hyperdiploid ALL group (P = .017). Another association (P = .029) was found between CD79b negativity and the t(12;21) group. CD200 was widely expressed in all groups. CONCLUSION There is a significant correlation between some markers, and certain ALL recurrent cytogenetic subgroups (CD123 and hyperdiploidy, CD79b negativity, and ETV-RUNX1 group) have good prognostic value. CD200 can be used as MRD markers in ALL patients and can also can serve as therapy targets.

Abstract
PURPOSE Human bocavirus (HBoV) exsits in four genotypes: 1 to 4, with HBoV-1 being the most prevalent genotype. The aim of the current study was to genetically analyze the full-length genome of the HBoV-1 of recently detected Egyptian strains. METHODOLOGY Seven overlapping sets of primers were developed to amplify an almost complete HBoV-1 genome from the clinical samples. The primer sets were tested on three recently identified Egyptian HBoV-1 strains with viral loads ≥105 ml-1. Sequencing was conducted using the same sets of primers. HBoV-1 virus strains were genetically analyzed based on the sequences of their complete genomes and the individual ORFs. RESULTS The new sets of primers successfully amplified the three tested strains. Sequence analysis of the full-length genome of the HBoV-1 revealed a considerable level of genetic heterogenicity between different strains. Based on the full genome and VP1 ORF, HBoV-1 viruses were clustered into three main lineages, A to C, and lineage A was further subdivided into three sublineages, A1-A3. The Egyptian strains were clustered within two sublineages, A1 and A2. New amino acid substitutions were detected in NS1 and VP1/VP2 proteins. Both inter- and intragenomic recombination events were detected among the Egyptian strains. CONCLUSION The existence of both intragenomic recombination event and multiple amino acid substitutions in the examined Egyptian HBoV-1 strains elucidates considerable level of genetic alterations among bocaviruses. Their possible effects on the virus virulence and multiplication efficiency need to be investigated.

Abstract
Background: High-risk types of human papillomavirus (HR-HPV) may play a role in the development of epithelial ovarian cancer (EOC). The aim of this study was to determine any HPV genotypes and correlations to CADM1, PAX1, MAL and ADCYAP1 gene methylation in Egyptian EOC patients. Materials and methods: The prevalence of HR-HPV in 100 formalin fixed paraffin embedded EOC tissues was determined using nested polymerase chain reaction (PCR) with MY09/MY11 and GP5+/GP6 + primers to amplify a broad spectrum of HPV genotypes in a single reaction. DNA sequencing was applied to identify HPV genotypes for the positive samples. All samples negative for HPV were re-analyzed for HR-HPV and low-risk HPV subtypes using type specific primers. Results: The prevalence of HPV was 10% in our EOC cases. HPV-16 and HPV-18 were the predominant genotypes followed by HPV−33, all being associated with advanced stages. Other HR-HPV and low risk HPV genotypes were not found. CADM1 was hypermethylated in 100% of patients infected with HPV-16 and HPV-33 and in 75% of patients infected with HPV-18. Hypermethylation of PAX1 was evident in 80% and in 75% of patients infected with HPV-16 and HPV-18 while MAL was hypermethylated in 100% and ADCYAP1 was hypermethylated in 60% and in 75%, respectively. Conclusion: The presence of high risk HPV genotypes among epithelial ovarian carcinoma may reflect an importance of infection in the pathogenesis of EOC. In HR-HPV infected cancers, DNA methylation may be one of the mechanisms triggering the alteration in CADM1, PAX1, MAL and ADCYAP1 gene expression levels.

Abstract
OBJECTIVES To detect FMS-like tyrosine kinase-3 internal tandem duplicate (FLT3 ITD) mutation, Myeloproliferative leukemia virus oncogene (cMPL) and Ephrin A 4 receptor (EphA4) expressions in Acute myeloid leukemia (AML) and their correlation to patient's clinicopathological characteristics and survival. METHODS RNA was extracted from blood samples of 58 AML patients (39 adults and 19 children) and 20 age and sex matched controls. FLT3 ITD mutation, cMPL and EphA4 expression was studied using RT-PCR and correlated to the clinical and survival data of the patients. RESULTS FLT3 ITD mutation, cMPL and EphA4 expression was positive in 35.9%, 76.9% and 56.4% of adult AML patients respectively and in 15.8%, 47.4% and 36.8% of pediatric AML patients respectively. 76.9% of adult and 89.5% of pediatric patients expressed CD33. 64.1 % of adults and 42.1% of children expressed CD34. CD34 expression was significantly associated with both FLT3 ITD mutation and cMPL expression. CD34, FLT3 and cMPL negative cases have significantly higher overall survival than positive cases. CONCLUSION CD34 expression is significantly associated with both FLT3 ITD mutation and cMPL expression which could be used as a marker for low survival. Normal FLT3 and negative expression of CD34 and cMPL may predict a longer overall survival. Further studies are needed to investigate the mechanism that may correlate CD34 to both markers.

Abstract
Background: Breast cancer is the commonest cancer in Egyptian females. Nrf2 is involved in oxidative stress while P73 functions in response to DNA damage. This study aimed to assess the role of Nrf2 promoter and P73 G4C14 to A4T14 SNPs in breast cancer in Egypt. Patients: Eighty-five female patients with breast tumours (41 malignant, 44 benign) were included. Nrf2 (rs6721961) and p73 (G4A) SNPs were determined by PCR- CTPP assay. Results: Genotype frequencies of the Nrf2 promoter SNP were 34.2% and 37.9% for AA in benign and malignant groups respectively, and 43.9% and 40.5% for CC and, 21.9 % and 21.6% for CA. Genotype frequencies for the P73 G4A SNP were 52.9% and 44.7% for GA in benign and malignant groups respectively, and 47.1% and 55.3% for GG. Discussion: Nrf2 genotypes in pre - and post-menopausal patients, showed significantly different distributions in the 2 patient groups, the AA genotype being significantly more common in pre-menopausal patients. The P73 G4A SNP showed no relation to age of disease onset. Conclusion: The Nrf2 (rs6721961) AA genotype might be related to early breast cancer onset. In contrast the P73 G4A polymorphism showed no relation to either disease risk or age at presentation.

Abstract
BACKGROUND AND AIM Crohn's disease is a relapsing inflammatory condition afflicting the digestive tract. Drugs used for treatment of Crohn's disease may be associated with serious side effects. Endogenous opioid peptides modulate inflammatory cytokine production. Opioid antagonists have been shown to play a role in healing and repair of tissues. This work was designed to detect the possible beneficial effects of opioid antagonist naltrexone in indomethacin-induced Crohn's disease in rats. EXPERIMENTAL APPROACH Enteritis was induced in male albino rats by two subcutaneous injection of indomethacin in a dose of 7.5mg/kg 24h apart started on day one. Salfasalazine, naltrexone and their combination were administered orally from day one of induction of enteritis to day 10. Disease activity index, serum levels of C-reactive protein and tumor necrosis factor-α, macroscopic and microscopic pathological scores and in vitro motility studies were evaluated. RESULTS Induction of enteritis resulted in significant increase of disease activity index, significant elevation of serum levels of C-reactive protein and tumor necrosis factor-α, significant deterioration of pathological scores and significant increase in the mean contractility response of the isolated ileal segments compared with normal untreated rats. Treatment with sulfasalazine, low dose of natrexone or their combination resulted in significant improvement of all measured parameters compared with enteritis group. CONCLUSION The current finding could provide new interesting opportunity for developing new therapeutic approaches for treatment of Crohn's disease. Use of naltrexone, especially in small dose, has little side effects making it of interest for treatment of Crohn's disease. Also, it provides the possibility of reduced doses of other drugs if it is used as combined therapy.

Abstract
Human bocavirus (HBoV) is a prevalent virus worldwide and is mainly associated with respiratory disorders. Recently, it was detected in several disease conditions, including cancers. Colorectal cancer (CRC) is the third main cause of cancers worldwide. Risk factors that initiate cell transformation include nutritional, hereditary and infectious causes. The aim of the current study was to screen for the presence of HBoV in solid tumors of colorectal cancer and to determine the genotypes of the detected strains. Surgically excised and paraffin-embedded colorectal cancer tissue specimens from 101 male and female patients with and without metastasis were collected over the last four years. Pathological analysis and tumor stages were determined. The presence of HBoV was screened by polymerase chain reaction, and the genotype of the detected HBoV was determined by direct gene sequencing. Most of the examined specimens were adenocarcinoma with mucinous activity in many of them. Twenty-four out of 101 (23.8 %) CRC tissue specimens were found to contain HBoV-1. Low sequence diversity was recorded in the detected strains. The virus was detected in both male and female patients with an age range of 30-75 years. It is proposed that HBoV-1 could play a potential role in the induction of CRC.

Abstract
BACKGROUND The objectives of this study aimed to detect a CYP2B6 polymorphism in de novo cases of acute myeloid leukemia patients and identify any role in disease progression and outcome. MATERIALS AND METHODS DNA was isolated from peripheral blood of 82 newly diagnosed acute myeloid leukemia cases and the CYP2B6 G15631T gene polymorphism was assayed by PCR restriction fragment length polymorphism (PCR-RFLP). RESULTS The frequency of the GG genotype (wild type) was 48 (58.5%) and that of the mutant type T allele was 34 (41.9%). GT genotype heterozygous variants were found in 28 (34%), and TT genotype homozygous variants in 6 (7.3%) cases. We found no significant association between the CYP2B6 G15631T polymorphism and complete response (CR) (p-value=0.768), FAB classification (p-value=0.51), cytogenetic analysis (p-value=0.673), and overall survival (p-value=0.325). Also, there were no significant links with early toxic death (p-value=0.92) or progression- free survival (PFS) (p-value=0.245). CONCLUSIONS Our results suggest that the CYP2B6 polymorphism has no role in disease progression, therapeutic outcome, patient free survival, early toxic death and overall survival in acute myeloid leukemia patients.

Abstract
The commonest cancer in Egyptian females occurs in the breast cfDNA is a non-invasive marker for tumor detetion and prognostic assessment in many types of cancer including breast cancer. This study aimed to assess the role of cfDNA and its fragmentation pattern in breast cancer prognosis and treatment response. Forty female patients with malignant breast tumors and a comparable group of healthy blood donors were enrolled prospectively. cfDNA levels and fragmentation patterns were investigated after cfDNA extraction, gel electrophoresis and gel analysis. The percentage of breast cancer patients positive for cfDNA (92.5%) was significantly higher than that of controls (55%). Also, mean concentration of cfDNA was significantly higher than in the control group (<0.05). Most Her-2 positive patients had long cfDNA fragments, this being significant as compared to Her-2 negative patients (<0.05). Metastasis was also positively linked to significantly higher cfDNA (<0.05) and the mean cfDNA integrity index was significantly higher in non-responders compared to treatment responders (<0.05). In conclusion, both qualitative and quantitative aspects of cfDNA and its different fragments in breast cancer patients could be related to prognosis, metastasis and treatment response. Long cfDNA fragments could be particularly useful for prediction purposes.

Abstract
BACKGROUND AND OBJECTIVES Detection of chromosomal abnormalities in myeloproliferative disorders is important for proper diagnosis of these disorders. This study has investigated the presence of JAK2 mutation (V617F) in Egyptian patients with myeloproliferative disorders referred to National Cancer institute, Cairo University. METHODS The study involved 110 cases of Philadelphia negative Myeloproliferative diseases (MPDs), 70 cases with Polycythemia Vera (PV), 24 cases with Essential Thrombocytosis (ET) and 16 cases with Idiopathic Myelofibrosis (IMF) and 20 cases as a control group which represented as; (10 cases with secondary erythrocytosis, 1 case with reactive thrombocytosis, 4 cases as normal control and 5 as Philadelphia positive Chronic Myeloid Leukemia cases), they were collected from National Cancer Institute (NCI) over 3 years. We used ARMS technique for mutation detection. RESULTS The frequency of the V617F JAK2 mutation was highest in patients with PV where 56 out of 70 cases (80%) carried the mutation, followed by ET with 6 of 24 (25) and IMF with 2 of 16 (12.5%) . None of the cases with secondary Erythrocytosis, reactive thrombocytosis, the normal controls or Philadelphia positive CML cases carried the mutation. CONCLUSIONS Our results are concordant with international published results for detection of this mutation. It is unequivocal now that V617F is met in many MPDs especially PRV. Finding this mutation in those patients is thought to have a big impact on the diagnosis and treatment of these disorders.

Abstract
BACKGROUND AND OBJECTIVES Total thyroidectomy is indicated in most cases with postcricoid carcinoma, circumferential hypopharyngeal carcinoma and in advanced laryngeal carcinoma. Persistent hypoparathyroidism is a frequent complication after total thyroidectomy which is difficult to manage unlike hypothyroidism. This study was to assess the feasibility of parathyroid gland autotranplantation after total thyroidectomy in advanced carcinomas and their effectiveness in preventing persistent hypoparathyroidism. METHODS This study included 26 patients with hypopharyngeal and laryngeal carcinoma presented to National Cancer Institute, Cairo University. Total thyroidectomy and total parathyroid gland excision were performed as a part of adequate oncologic surgical procedure. The parathyroid glands were identified, resected and stored in iced saline. Histological confirmation was necessary before implantation into separated muscle pockets in the anterior forearm muscles. Regular samples were drawn to assess serum parathormone and calcium levels. RESULTS All patients experienced hypocalcaemia within 1-5 days after operation. Only one patient experienced parathyroid graft failure while the remaining patients were normocalcemic during follow up after surgery, indicating functioning parathyroid grafts. CONCLUSIONS Parathyroid gland autotranplantation is a simple safe technique with high success rate in preventing persistent hypoparathyroidism after total thyroidectomy in surgical management of advanced hypopharyngeal and laryngeal carcinomas.

Abstract
BACKGROUND Type 1 diabetes mellitus (TIDM) results from an immune-mediated destruction of insulin-producing-cells in the pancreatic islets of Langerhans. There are clear differences in immunogenetic predisposition to type1 diabetes among countries. Studies have indicated that vitamin D supplementation in early childhood decreases the risk of TIDM. Vitamin D exerts its action via the nuclear vitamin D receptor (VDR), which shows an extensive polymorphism. VDR gene polymorphisms have been associated with altered gene expression or gene function. Four single nucleotide polymorphisms (SNPs) in the VDR gene produce variation in four recognition sites. These recognition sites variants include Fok I, Bsm I, Apa I and Taq I. AIM OF THE STUDY TO investigate the relationship between VDR gene polymorphisms (at positions Taq I and Apa I) and the incidence of TIDM in Egyptian peoples. SUBJECTS AND METHODS This study included 74 patients with type 1 DM in addition to 28 healthy age and sex matched control subjects. All of them were subjected to full history taking and clinical examination. Three ml of venous blood were withdrawn from each patient at fasting and postprandial times and used for genomic DNA extraction, estimation of Hb A1C, as well as, fasting and postprandial C-peptide and blood glucose levels. RESULTS Apa I recognition site was found in low frequency in diabetic patients (14/74) 18.9% while, its frequency was high (16/28) 57.1% among normal subjects. Taq I has two recognition sites. The first was found at nucleotide number 293 that was found in a frequency of (2/28) 7.1% in normal non-diabetic individuals while it was detected in (14/74) 18.9% in diabetic patients. The second Taq I recognition site was found at nucleotide number 494 without any differences between diabetic and normal individuals. CONCLUSION This study indicates that there is an association between VDR genetic polymorphism and incidence of TIDM in Egyptian patients.

Abstract
Background Hepatitis C virus (HCV) and Schistosoma mansoni are major causes of chronic liver disease (CLD) in which immune alteration is common. Recent studies suggested that certain platelets and lymphocytes activation markers may have an impact on progression of CLD. This study aimed to evaluate the potential of platelets and lymphocytes activation molecules expression on the pathogenesis of CLD in distinct or concomitant chronic HCV and schistosomiasis mansoni infections. Methods The study populations were divided into group-I: patients with chronic schistosomiasis mansoni, group-II: HCV patients without cirrhosis, group-III: patients with combined liver diseases without cirrhosis, group-IV: patients with chronic HCV and liver cirrhosis and group-V: Age and sex matched healthy individuals as normal controls. All groups were subjected to full clinical evaluation, ELISA anti-HCV antibodies screening, parasitological examination for diagnosing S. mansoni and flow cytometry for lymphocyte (CD3, CD4, CD8, CD19, CD22, & CD56) and platelets activation (CD41, CD42 & CD62P (P- selectins)) markers. Results The platelet count was significantly decreased in HCV and/or S. mansoni patients. The total T-lymphocytes and T-helper cells were significantly reduced, while T-cytotoxics were increased. The patients possessed a significantly higher platelets activation marker; CD62P (P-selectins) and higher mean fluorescent intensity (MFI) positivity. There were considerable correlations between platelets count and both of CD62P and MFI. Conclusion Our Findings suggest an increased expression of certain platelets and lymphocytes activation markers in chronic HCV and S. mansoni induced CLD that may have a role in disease progression.

Abstract
Hepatitis C virus (HCV) and Schistosoma mansoni are two major causes of chronic liver disease (CLD). Both immune alteration and thrombocytopenia are common complications in the majority of cirrhotic patients. The current study aimed to monitor the effect of T cell profile and platelets activation on the pathogenesis of liver cirrhosis in patients suffered from single or concomitant schistosomiasis and HCV infections. The subjects were divided into 4 groups: Group I, patients infected with schistosomiasis; Group II, patients infected with HCV; Group III, patients with combined liver diseases and Group IV: healthy individuals. All groups were subjected to full clinical evaluation as well as laboratory examination including ELISA anti-HCV antibodies screening, parasitological examination, and complete blood picture as well as flow cytometry for CD41, CD42, CD62P (P selectin), CD63, CD4 and CD8. The platelets count was significantly decreased in HCV and/or schistosoma infected patients compared to controls. The percentage of the total T-lymphocytes and T-helper was significantly reduced in all infected groups, while the percentage of T-cytotoxic was increased. The patients possessed a significantly higher percentage of the platelets activation markers than control group. There were considerable correlations between the platelets counts and P selectin and MFI. Thrombocytopenia was a common finding in patients with CLD. Patients with CLD showed increased platelets activation which may contribute to the occurrence of thrombocytopenia and play a role in the pathogenesis of CLD. Infected patient showed reduction in the cell-mediated-immunity as evidenced by low T -helper cells.
