Abstract
BACKGROUND The wound-healing process in diabetic foot is affected by pro and anti-inflammatory markers, and any disruption in the inflammatory reaction interferes with tissue homeostasis, leading to chronic non-wound healing. AIM This study aimed to determine the diagnostic value and effect of CRP, IL-6, TNF, and HbA1c on initiation the and progression of diabetic foot ulcers. METHOD ELISA was used to quantify IL-6, TNF, CRP, and HbA1c in 205 patients with diabetes, and 105 were diabetic foot free. The prevalence and progression of diabetic foot were also evaluated. The area under the curve (AUC) was calculated using the receiver operating characteristic (ROC) curve to analyze the predictive values. Forward stepwise logistic regression analysis was used to compute the odds ratio (OR) and the corresponding 95% confidence intervals (CIs). RESULTS CRP, IL-6, and FBS were found to be significant predictors of diabetic foot (OR=1.717, 95% CI=1.250-2.358, P=0.001; OR=1.434, 95% CI=1.142-1.802, P=0.002; and OR=1.040, 95% CI=1.002-1.080, P=0.037), respectively. The AUCs for CRP, IL-6, and HbA1c in predicting diabetic foot were 0.839, 0.728, and 0.834, respectively, demonstrating a good predictive value for each diagnostic marker. CONCLUSION The current study demonstrated that IL-6, CRP, and HbA1c may be useful biomarkers to indicate diabetic foot progression. Furthermore, our findings showed a substantial relationship between CRP and HbA1c in individuals with diabetic foot conditions.

Abstract
BACKGROUND Leptin (LEP) is an anti-obesity hormone that regulates food intake, energy expenditure, and glucose metabolism. The genetic variants in LEP and the LEP receptor (LEPR) gene may play an important role in the pathogenesis of type 2 diabetes mellitus (T2DM) and obesity. The current study aimed to investigate the association of serum LEP levels, and LEP polymorphisms in LEP (rs7799039, 2548 G/A) with T2DM in Egyptian patients. METHODS A total of 205 subjects were included in the present case-control study, consisting of 100 T2DM patients and 105 healthy controls. The anthropometric, psychometric, and biochemical measurements were taken from all the subjects. The genotyping of LEP gene variants was carried out by polymerase chain reaction TaqMan technology. Serum LEP levels were measured by the ELISA technique. RESULTS T2DM patients had significantly elevated levels of glycated haemoglobin (HbA1c), fasting blood sugar (FBS), postprandial blood sugar (PPBS), international normalisation ratio (INR), creatinine, urea, cholesterol, triglyceride (TG), and low-density lipoproteins (LDL) and significantly decreased high-density lipoprotein (HDL) compared to healthy subjects. serum LEP levels were significantly decreased p (<0.001) as compared to the control group. LEP gene SNP rs7799039 was associated with an increased diabetic risk with A allele being more frequent in T2DM patients than control subjects. The distribution of the AA genotype and GA genotype of LEP SNP rs7799039 was higher in the diabetic group than control one. In addition, AA + GA genotype carriers had significantly elevated HbA1c, FBS, PPBS, TG, and LDL levels and on the contrary, decreased serum LEP levels compared to GG homozygotes. CONCLUSION The genetic polymorphism rs7799039 showed a highly significant correlation with blood LEP. The co-dominant and dominant models of the LEP genetic polymorphism (rs7799039, 2548 G/A) were shown to have a significant correlation with complicated and uncomplicated diabetes individuals, but we have found that serum LEP levels were inversely related with control and diabetes patients. A positive significant association was found between LEP genetic polymorphism (rs7799039, 2548 G/A) and serum LEP in patients and controls. LEP levels and its rs7799039 genetic variant may play a vital role in increasing T2DM susceptibility.

Abstract
BACKGROUND Up to date, a well-defined microRNAs (miRNAs) profile involved in hepatocellular carcinoma (HCC) pathogenesis remains indecisive. Thus, employing miRNAs for HCC diagnosis is demanded for early therapeutic interventions. We aimed to evaluate the usage of miRNAs set related to the SuperPath: miRNAs involved in DNA damage response pathway as effective biomarkers for HCV-related HCC diagnosis. RESULTS The study enrolled 97 patients with HCV-related HCC, 84 with hepatitis C virus (HCV), 97 with liver cirrhosis (LC), and 84 healthy individuals. Serum miRNA-23a, miRNA-203, miRNA-100-5p, and miRNA-16 were quantified using qRT-PCR experiments, AFP and routine LFTs were estimated via standard techniques. Pathway enrichment analysis along with the construction of miRNAs regulatory network were performed. With respect to healthy individuals, miRNA-203, miRNA-100-5p, and miRNA-16 were significantly downregulated in HCC, HCV, and LC groups, while miRNA-23a showed significant upregulation (p < 0.001). miRNAs exhibited significant correlations with AFP, ALT, AST, and albumin. Also, elevated levels of miRNA-23a were recognized in patients with multiple focal lesions and/or lesion size > 5 cm. Additionally, the diagnostic performance of miRNA-23a expression level at a selected cut-off value of 3.99 overtakes AFP, while expressions of miR-203, miRNA-100-5p, and miRNA-16 represent poor diagnostic outcomes. CONCLUSIONS Keeping in mind the individual variability and high level of heterogeneity in HCC, our data revealed the diagnostic value of miRNA-23a expression in HCV-related HCC patients. Further extra in silico HCC-specific microRNAs sets are demanded in diagnosis.

Abstract
Background & Aims This research aimed to determine how variations in the vitamin D receptor gene affected the response of H. pylori infections to eradication therapy. Patients and Methods On 105 adult H. Pylori-positive patients, a prospective cohort study was carried out. PCR was used to genotype all patients' VDR gene polymorphisms. The patients in the study received standard triple eradication medication (clarithromycin 500 mg, amoxicillin 1000 mg, and omeprazole 20 mg) twice daily for 14 days. A stool test for H. pylori Ag was conducted 4 weeks following the end of treatment. Results In our study, the usual triple therapy's H. pylori eradication rate was 75.2%. The successful eradication of H. pylori and VDR rs 2228570 gene polymorphisms was more prevalent in CT gene polymorphism (64.6%) compared to non-responders (19.2%), while treatment failure was more prevalent in CC gene polymorphism (73.1% in non-responders compared to responders 24.1%), which is statistically significant. In regards to the eradication of H. pylori and VDR rs7975232 gene polymorphisms, the success of eradication was more prevalent in AC gene polymorphism (54.4%) vs non-responders (30.4%), while all patients (14) with gene AA (17.7%) are responders to standard treatment, while the failure of treatment was more prevalent in CC gene polymorphism (69.2% in non-responder vs 27.8% in responders) which is statistically significant. Our findings demonstrated a strong correlation between patients' responses to H. pylori treatment and polymorphisms in the VDR gene (ApaI and TaqI) (P 0.05). Conclusion As far as we are aware, this is the first study to identify a potential link between the FokI and Apal VDR polymorphism and treatment response in H pylori-positive patients. To evaluate the findings, more research with larger number of patients and different population is required.

Abstract
Background and Aim: Non-alcoholic fatty liver (NAFLD) is one of the most common progressive metabolic disorders worldwide. There are increasing scientific interests nowadays for the association between vitamin D status and Non-alcoholic fatty liver. Earlier studies have revealed that vitamin D deficiency is highly prevalent in Non-alcoholic fatty liver patients that contributes to poor outcomes. Hence, the present study aimed to assess the efficacy and safety of oral cholecalciferol on Non-alcoholic fatty liver patients.Subjects and Methods: This study was conducted on 140 patients that were randomized either to group 1 that received the standard conventional therapy in addition to placebo or group 2 that received the standard conventional therapy in addition to cholecalciferol during the 4 months study period.Results: At the end of the study group 2 revealed significant decrease (p < 0.05) in the mean serum level of TG, LDL-C, TC, hsCRP as compared to their baseline results and group 1 results. Additionally, a significant improvement in the serum levels of ALT (p = 0.001) was seen in group 2 at the end of the study when compared to group 1. Whereas group 1 did not show any change in these parameters when compared to group 2 and their baseline results.Conclusion: Cholecalciferol was shown to have beneficial effects on serum ALT levels, hsCRP levels and lipid profile of NAFLD patients.Clinical Trial Registration:https://prsinfo.clinicaltrials.gov/prs-users-guide.html, identifier NCT05613192

Abstract
BACKGROUND & AIMS Coronavirus disease - 2019 (COVID-19) is a major pandemic that causes high morbidity and mortality rates. AIM OF THIS STUDY to detect the relations between many risk factors, ACE-2, MCP-1, Micro RNA 146 gene expression, and COVID-19 infection and disease severity. METHODS This study was carried out on 165 cases of COVID-19 and 138 controls. ACE2 and MCP1 levels were measured in COVID-19 cases and control by ELISA and micro-RNA-146 expression by PCR. RESULTS We found an increased blood level of ACE2 and MCP1 in COVID- 19 patients than in healthy persons and a significant down-regulation of micro-RNA 146 gene expression in cases than in controls. There was a significant correlation between increased blood level of ACE2, regulation of micro-RNA 146 gene expression and severity of lung affection, a significant correlation was found between increased blood level of MCP1 and thrombosis in COVID-19 patients. Neurological complications were significantly correlated with more viral load, more ACE2 blood level, and down regulation of micro RNA146 expression. CONCLUSION High viral load, increased blood level of ACE2, and down-regulation of micro-RNA 146 expression are associated with more severe lung injury and the presence of neurologic complications like convulsions and coma in COVID-19 Egyptian patients.

Abstract
In Egypt, hepatocellular carcinoma (HCC) ranks as the second largest cause of cancer mortality. PRDM1 is a tumor suppressor gene essential for the differentiation and regulation activity of plasma cells and T cells. It plays a vital role in T cell exhaustion of chronic viral infection and HCC. We aimed to study the role of PRDM1 gene polymorphism in HCV and HCC-related to hepatitis C virus (HCV) progress in Egyptians. The case-control study included 300 Egyptian patients divided into 100 HCC,100 cirrhosis, and 100 control. Laboratory investigations were done for some clinicopathological biomarkers, including liver function tests, complete blood picture, serum alpha-fetoprotein, and hepatitis markers (HBsAg, anti-HCV-Ab). TaqMan allelic discrimination assay technique was used to genotype PRDM1 gene polymorphism. Multivariant analysis (logistic regression) assessed the association between the polymorphisms with HCC progression and designed the suggested model for HCC prediction. The frequencies of the G allele and GG phenotype in the control group were significantly more than that of the HCC and cirrhosis group. However, GA genotypes and A allele frequencies significantly increased in the HCC patients than in cirrhosis and controls. In addition, by comparing the HCC group and the non-HCC group (controls and cirrhotic patients), the subjects carrying AA or GA have 2 times more risk to develop HCC than those carrying GG genotypes (odd ratio = 2.045% and 95% confidence interval are (1.123-3.722) p = 0.019). Multivariate analysis results suggested a model of Aspartate transaminase (AST), Albumin, and PRDM1 polymorphism to predict the risk of HCC in Egyptians. In addition, PRDM1 polymorphism has an association with HCC prognosis (tumor size). For PRDM1 polymorphism, the A allele and AA might be considered as HCC-related to the HCV risk factor. In addition, AST, Albumin, and PRDM1 polymorphism predict the risk of HCC in Egyptians Therefore, the polymorphism might help in identifying the susceptible Egyptians to HCC. In addition, polymorphism might have a role in HCC prognosis.

Abstract
BACKGROUND AND AIMS SARS-CoV-2 infection has been recorded in 230 countries to date. Obesity has a negative impact on one's quality of life and is one of the main causes of mortality globally. Obesity affects the immune system, making the host more susceptible to infectious infections. Also, obesity commonly provokes the severity of respiratory diseases so the correlation of LEP rs7799039 Polymorphism in corpulent patients with COVID-19 infection was clearly investigated in the current study. METHODS A total of 232 patients were recruited, 116 patients were obese with COVID-19 infection, and 116 patients were non obese COVID-19. Fasting blood glucose test (FBG), hemoglobin A1C (HbA1C), complete blood count (CBC), international normalized ratio (INR), urea, alanine transaminase (ALT), aspartate aminotransferase (AST), D dimer and C-reactive protein (CRP) were estimated. C.T. scan was performed for each patient, and C.T. severity score was calculated. Genotyping for the leptin rs7799039 SNPs was performed by TaqMan® (Applied Biosystems Step One TM Real-time PCR). RESULTS Regarding LEP polymorphism, all individuals of non-obese groups significantly had the homozygous allele GG (100%), whereas only 56% of obese groups had GG alleles (P = 0.001). The severity scores significantly (P = 0.001) varied regarding LEP polymorphism regarding Rs7799039, where the largest proportion of those with Grade IV had the homozygous allele AA (57.1%). CONCLUSION There was a correlation between the leptin gene allelic discrimination and COVID-19 CT brutality in obese patients. The A allele was considered a risk factor for severity in COVID-19 patients while the G allele contributes to decreasing that risk.

Abstract
Background & Aims:
The aim of the study was to evaluate serum c-reactive protein (CRP), ascitic procalcitonin (PCT) and monocyte chemotactic protein-1 (MCP-1) in the diagnosis of spontaneous bacterial peritonitis (SBP) in cirrhotic patients.
Methods:
A cross-sectional analytic study that included 199 patients with decompensated cirrhosis (101 with SBP and 98 without SBP). Patients were classified according to Child-Pugh criteria. Ascitic PCT and MCP-1 were measured by enzyme-linked immunosorbent assay. Serum CRP, liver and renal functions were assessed.
Results:
Three markers are significantly elevated in SBP patients than those without ascites. Using the ROC curve at AUC 0.883 and a cut-off value of >186 ng/ml, the diagnostic performance of ascitic MCP-1 level was higher than CRP (AUC 0.562) and ascitic fluid procalcitonin (AUC 0.751) in the diagnosis of SBP. The sensitivity and specificity were 86.15% and 79.59% at the cutoff of 186 ng/ml for MCP-1, 65.4 and 75.5 at ≥ 1 ng/ml for PCT, and 52.5 and 64.3, respectively for at 11.2 mg/dl CRP.
Conclusion:
Ascitic MCP-1 has a better diagnostic value with higher sensitivity and specificity in diagnosis SBP compared to CRP and procalcitonin which has higher diagnostic accuracy than CRP. Further studies with a large number will be necessary to evaluate the usefulness of these markers in diagnosis, follow-up and relation to morbidity and mortality of SBP patients.

Abstract
Background Vitamin D is a regulatory factor for skin immune functions through vitamin D receptor, which is expressed on many immune cells. Vitamin D receptor is located on chromosome 12q 13.11 and has many single nucleotide polymorphisms. Some of them were hypothesized to be associated with psoriasis. Psoriasis is a genetic disease that is greatly affected by environmental factors. Methods A total of 135 psoriasis patients and 114 healthy controls were recruited. Both had a measurement of serum vitamin D and two vitamin D receptor variants:, rs1544410: G > A (HGVS:NC_000012.12:g.47846052) and rs7975232: C > A (HGVS: NC_000012.12:g.47845054). We assessed the relationship between vitamin deficiency as well as the two gene polymorphisms with psoriasis susceptibility and severity. Results Serum vitamin D levels were not significantly different between cases and controls. However, a significant association between vitamin D levels and severity was observed. We attributed this to our finding that rs7975232 was more significantly polymorphic among cases than controls, while rs1544410 polymorphism did not show a significant difference among the 2 groups. Conclusion We did not find a significant difference in serum vitamin D levels between cases and controls. Yet, psoriasis severity was significantly associated with serum vitamin D levels. We attributed this to other findings that the vitamin D receptor rs7975232 gene is polymorphic in psoriasis patients. At the same time, rs1544410 was not significantly more polymorphic in psoriasis patients. Both genes’ polymorphisms were associated with severe psoriasis.

Abstract
Background: Early detection and screening of breast cancer (BC) might help improve the prognosis of BC patients. This study evaluated the use of serum microRNAs (miRs) as non-invasive biomarkers in BC patients. Methods: Using quantitative real-time polymerase chain reaction, we evaluated the serum expression of four candidate miRs (miR-155, miR-373, miR-10b, and miR-34a) in 99 Egyptian BC patients and 40 healthy subjects (as a control). The miRs expression was correlated with clinicopathological data. In addition, the sensitivity and specificity of the miRs were determined using receiver operating characteristic (ROC) curve analysis. Results: Serum miR-155, miR-373, and miR-10b expression were significantly upregulated (p < 0.001), while serum miR-34a was downregulated (p < 0.00) in nonmetastatic (M0) BC patients compared to the control group. In addition, serum miR-155 and miR-10b were upregulated in BC patients with large tumor sizes and extensive nodal involvement (p < 0.001). ROC curve analysis showed high diagnostic accuracy (area under the curve = 1.0) when the four miRs were combined. Serum miR-373 was significantly upregulated in the human epidermal growth factor 2−negative (p < 0.001), estrogen receptor−positive (p < 0.005), and progesterone receptor (PR)-positive (p < 0.024) in BC patients, and serum miR-155 was significantly upregulated in PR-negative (p < 0.001) BC patients while both serum miR-155 and miR-373 were positively correlated with the tumor grade. Conclusions: Circulating serum miR-155, miR-373, miR-10b, and miR-34a are potential biomarkers for early BC detection in Egyptian patients and their combination shows high sensitivity and specificity.

Abstract
OBJECTIVE Spontaneous Bacterial Peritonitis (SBP) is one of the most serious liver cirrhosis with ascites complications. Vitamin D (Vit D) deficiency has been associated with a high risk of infection and mortality in cirrhotic patients. Herein, the assessment of Vit D level as a prognostic marker in SBP patients and the impact of Vit D supplementation on their treatment plan was studied as well. PATIENTS AND METHODS Ascetic patients with SBP and Vit D deficiency were divided randomly into treatment and control groups. The control group received standard treatment without Vit D and the treatment group received standard treatment plus Vit D. Clinical monitoring of Vit D was done over 6 months. RESULTS At baseline, all patients in both groups revealed an elevated serum and ascetic TLC, AST, ALT, total and direct bilirubin, in addition to elevation in INR and procalcitonin (PCT) level. Univariate regression analysis confirmed that deficiency of Vit D was an independent predictor of infection and mortality (p < 0.01; Crude Hazard Ratio: 0.951). Over 6 months, the study revealed significant improvement in serum Vit D level in the treatment group (34.6 ± 9.2 and 18.3 ± 10.0 ng/mL; p < 0.001). Moreover, a statistically significant increase in survival rate (64% vs. 42%; p < 0.05) and duration (199.5 days vs. 185.5 days; p < 0.05) were recorded as well. Univariate and multivariate regression analysis confirmed that Vit D supplementation was positively correlated to survival over 6 months (p < 0.001; Adjusted Hazard Ratio: 0.895). CONCLUSIONS Vit D deficiency is prevalent in SBP cirrhotic patients and is used as an independent predictor of infection and death. Therefore, Vit D supplementation revealed improvement in their response to treatment.

Abstract
Abstract
Background
Atopic dermatitis is characterized by impaired skin barrier and altered cutaneous innate immunity. The estimated prevalence among Egyptian children was 10–12%. Several studies suggest that it may be associated with systemic comorbidities other than the spectrum of atopy, such as metabolic syndrome and other inflammatory conditions. The aim of this study is to compare the profile of systemic conditions of diabetes, dyslipidemia, and multiple inflammatory markers in children with and without diagnosed atopic dermatitis.
Methods
One hundred atopic dermatitis patients and 101 normal controls were collected from outpatient clinic based on their clinical condition, both had measurement of body mass index, blood sugar, serum insulin, lipid profile, C reactive protein, and gamma-glutamyl transferase.
Results
Children diagnosed with atopic dermatitis had significantly higher levels of body mass index (34.7 ± 5.7 vs 26.1 ± 4.9), fasting glucose (143.2 ± 30.3 vs 100.8 ± 16.0), serum insulin (11.3 ± 4.4 vs. 4.6 ± 3.0), serum triglycerides (194.1 ± 38.1 vs 156.2 ± 31.6), total cholesterol (198.4 ± 27.7 vs 163.7 ± 27.7), alkaline phosphatase (229.4 ± 89.8 vs. 189.4 ± 46.8), and gamma-glutamyl transferase (54.7 ± 19.9 vs 34.3 ± 9.5), C-reactive protein level was approximately four times higher (19.9 ± 13.2 vs 5.1 ± 3.4) and the immunoglobulin E level was approximately 10 times higher (2050.3 ± 843.8 vs 252.7 ± 103.1) than in controls
Conclusion
We found a positive relationship of atopic dermatitis with both diabetes and hyperlipidemia among children, and positive dose-response relationship of several non-traditional biomarkers of C-reactive protein, gamma-glutamyl transferase, and alkaline phosphatase with the presence and severity of atopic dermatitis.

Abstract
BACKGROUND/OBJECTIVES The pathophysiology of obesity is multifactorial, including genetic and environmental factors. Previous studies had highlighted the association of the leptin gene/receptor with obesity. We aimed to study the leptin gene rs7799039 single nucleotide polymorphism (SNP) in children, and its association with the children's characteristics. METHODS A cross-sectional analytic study that included 143 children with obesity (cases) and a comparable group of 86 lean children as controls. The anthropometric measures, blood pressure, and biochemical testing were done for all participants. The real-time polymerase chain reaction was used to detect rs7799039 SNP variant alleles and ELISA for leptin level assessment. RESULTS The distribution of rs7799039 SNPs genotypes GG/GA/AA was comparable between both groups. Testing children regardless of their body mass index showed that the abnormalities in blood pressure, lipids values, insulin resistance, and hepatic insulin sensitivity were significantly associated with increased leptin levels. Among cases, the abnormal metabolic status was associated with higher leptin levels. CONCLUSIONS The genotype' distribution of leptin gene rs7799039 SNP was similar in both children with obesity and those with normal-weight. The high blood pressure, abnormal lipid profile, and metabolic disturbances, were significantly associated with higher leptin levels and not with leptin gene rs7799039 SNP.

Abstract
Esophagectomy causes postprandial symptoms associated with an exaggerated postprandial gut hormone response. This study aimed to compare the gastrointestinal transit time of patients 1 year after esophagectomy with unoperated controls, including its relation to satiety gut hormone release. In this cross-sectional study, consecutive, disease-free patients after esophagectomy with pyloroplasty were compared with unoperated control subjects to assess gastric emptying (GE) and cecal arrival time (CAT). Serial plasma samples were collected before, and for 300 minutes after, a mixed-meal challenge. Body composition was assessed, and symptom scores were calculated. Eleven patients 1 year post-esophagectomy (age: 62.6 ± 9.8, male: 82%) did not show a significantly different GE pattern compared with 10 control subjects (P = 0.245). Rather, patients could be categorized bimodally as exhibiting either rapid or slow GE relative to controls. Those with rapid GE trended toward a higher postprandial symptom burden (P = 0.084) without higher postprandial glucagon-like peptide-1 (GLP-1) secretion (P = 0.931). CAT was significantly shorter after esophagectomy (P = 0.043) but was not significantly associated with GE, GLP-1 secretion, or symptom burden. Neither early nutrient delivery to the proximal small intestine nor to the colon explains the exaggerated postprandial GLP-1 response after esophagectomy. GE varies significantly in these patients despite consistent pyloric management.

Abstract
Introduction: The aim of this prospective study was to evaluate the correlation of primary (1ry)tumor metabolic activity parameters maximum standardized uptake value (SUVmax) and tumor SUVmax/liver average SUV ratio (TLR) in initial staging 18F-fluorodeoxyglucose (FDG) positron emission tomography / computerized tomography (PET/CT) scan with clinical, histopathological and molecular characteristics of breast cancer (BC) patients. Material and Methods: Initial staging PET/CT was performed in 40 cases with different stages of BC in the supine position. Tumor FDG uptake was qualitatively evaluated and quantitatively assessed using SUVmax and TLR. Results: Forty female patients with newly diagnosed BC were enrolled in our study, age range from 31-78 (mean 50.5 +/- SD11.7). All the 1ry tumors were detected with mean SUVmax 10.8(+/-SD 7.9). The mean /median SUVmax values of 1ry tumor was higher in premenopausal, stage III& IV, Estrogen Receptors negative(ER-), Progesteron Receptors negative(PR-), Her2neu positive patients, high nuclear grade (GIII), in triple negative molecular subgroup (TN), positive axillary nodal (ALNs)metastases, and (P value = 0.003, 0.017, 0.113, 0.089 0.01,0.002, 0.007 & 0.016 respectively). The mean/median TLR values was higher in premenopausal and Her2neu positive, GIII, TN molecular subtype patients, stage III& IV and in patients with positive ALNs, ER- &PR - patients (P value = 0.002, 0.0476, 0.005, 0.018, 0.039 and 0.022, 0.095 & 0.129 respectively). SUVmax of the 1ry lesion and TLR were moderately negatively correlated with the age of the patients (P value = 0.005 and 0.008 respectively), also they were moderately positively correlated with the size of the1ry tumor (P value = 0.019 and 0.036 respectively). Conclusion: The SUVmax of the 1ry tumor and TLR values had similar significant associations with different prognostic factors in BC

AIM This study is aimed at characterization of both antimicrobial and anti-biofilm activity of R-pyocin from clinical Pseudomonas aeruginosa against Gram-positive pathogens including Staphylococcus aureus. METHODS AND RESULTS Pyocinogenic P. aeruginosa was detected using reverse-side method, and pyocinogeny typing was confirmed using revised-spotting method. Transmission electron microscopy (TEM) was used for morphological characterization of R-pyocin and for detection of changes in membrane of R-pyocin-treated S. aureus. SDS-PAGE analysis was used for detection of the molecular weight of R-pyocin protein-subunits and Poisson-killing-distribution assay for burst-size calculation. Lipotechoic-acid (LTA) adsorption-assay was used to confirm whether LTA in Gram-positive bacteria served as R-pyocin receptor. Moreover, R-pyocin production at 10-60°C was assessed herein. Host-range of activity of R-pyocin was tested against antimicrobial resistant (AMR) pathogens. The anti-biofilm activity of R-pyocin was detected against sensitive bacterial strains. Chemical, enzymatic, pH and thermo-stability of R-pyocin were evaluated. TEM micrographs revealed a typical morphology of myotailocins indicating the production of R-pyocin designated as RPU15. TEM revealed pores formation in S. aureus membrane, and bacteriophage-like plaques were obvious on plates of R-pyocin-treated S. aureus. R-pyocin activity was neutralized by LTA of S. aureus and Listeria monocytogenes. Pseudomonas aeruginosa PU15 produced ~428 non-inducible R-pyocin particles. RPU15 sheath and tube protein-subunits exhibited a molecular weight of 38 and 23 kDa, respectively. RPU15 possessed activity against S. aureus, L. monocytogenes, Bacillus cereus and Candida albicans and reduced biofilm-biomasses of tested AMR strains. CONCLUSION Our results show the potential therapeutic use of R-pyocin due to its effectiveness on tested bacterial biofilms. SIGNIFICANCE AND IMPACT OF THE STUDY This is the first study that investigates antimicrobial and anti-biofilm activity of R-pyocin activity against S. aureus. R-pyocin shows new phenomenon of bacteriophage-like plaques. Our findings represent a future therapeutic agent targeting both methicillin-resistant and vancomycin-resistant S. aureus.

Abstract
Background & Aims:
The aim of this study was to assess IGF-1 in chronic liver diseases associated with HBV infection and describe the impact of liver status on IGF-1 variables.
Methods:
This cohort study included 348 subjects and conducted between December 2018 and December 2019 at El-Sahel Teaching Hospital, Cairo, Egypt. Subjects were divided into 4 groups: group I included HBV positive hepatocellular carcinoma patients “HCC” (n= 87), group II included HBV positive patients with liver cirrhosis “LC” (n = 87), group III included chronic hepatitis B (CHB) patients with neither HCC nor cirrhosis “CHB” (n = 87) and group IV of healthy volunteers as controls (n = 87). Serum IGF-1 was measured quantitatively using a commercially available enzyme immunoassay.
Results:
Serum levels of IGF-1 were measured in each of the 4 groups. The comparison showed marked differences in IGF1-related measures. It was found to be significantly reduced in HCC patients (32.08 ± 9.2 ng/ml), LC patients (50.6±14.1ng/ml) and CHB patients (61.4±14.3 ng/ml) in comparison to healthy subjects (140.4±49.9 ng/ml). The reduction of IGF-1 levels was also statistically significant between both HCC and LC patients and CHB patients also between HCC and LC patients.
Conclusion:
Serum IGF-1 levels are significantly reduced with the progression of hepatic disease in HBV patients and it may be a promising serological marker alone or in association with others for prediction of development of liver cirrhosis and HCC in chronic HBV patients.

Abstract
OBJECTIVE This review was conducted to systematically analyze the effects of aerobic exercise on immunological biomarkers to provide safe aerobic exercise recommendations and specifications for patients with COVID-19. MATERIALS AND METHODS A systematic search was conducted through MEDLINE (PubMed), Science Direct, Web of Science, Scopus, Cochrane Library, and SciELO databases. The search included the following keywords "immune system", "immune cell", or "immune function"; "aerobic training", "aerobic exercise", or "physical activity"; "human" or "adult"; and "cytokine", "killer cell", "T cell", "interleukin", "lymphocyte", "leukocyte" or "adhesion molecule". RESULTS Eleven studies met the inclusion and exclusion criteria of this search. The most used exercise prescriptions included walking, cycling, or running. The duration of exercise ranged from 18 to 60 min with an intensity of 55% to 80% of VO2max or 60%-80% of maximum heart rate. The frequency range was 1 to 3 times/week. The mainly increased immunological biomarkers included leukocytes, lymphocytes, neutrophils, monocytes, eosinophils, IL-6, CD16-56, CD16, CD4, CD3, CD8, and CD19. CONCLUSIONS This review demonstrated that patients with COVID-19 should follow a regular program of aerobic exercise for 20-60 min. This program should be in the form of cycling or walking with an intensity of 55%-80% VO2max or 60%-80% of maximum heart rate. This program should be repeated 2-3 sessions/week. These previous parameters could safely enhance immune functions without producing any exhaustion.

Abstract
BACKGROUND HCV treatment showed dramatical change due to the introduction of potent, strong, direct antiviral drugs. Before the appearance of Direct-acting antivirals, multiple therapeutic interventions were used for hepatitis C, but none of these interventions were effective on patient-centered outcomes. Direct-acting antivirals cause disruption of viral replication because they target specific nonstructural viral proteins. AIM To review the advantages of efficient HCV therapy and its long term drawbacks. METHODS A search of the literature published in indexed databases (PubMed, Medline In-Process, and Embase) within the last 5 years was conducted. Any duplicated citations were excluded before first-pass screening. Citations (titles and abstracts) were screened for eligibility by a single reviewer. Full texts (including congress abstracts, posters and other congress communications) of citations deemed relevant during title and abstract screening were retrieved for second-pass review. RESULTS Studies on the clinical effects of DAAs for hepatitis C show better tolerance, improved survival and fewer complications when compared to previous interferon therapy. CONCLUSION HCV treatment has improved dramatically. Since that time, there are multiple approved oral therapies all with high efficacy. The most important factor which should be considered during choosing appropriate therapy is to ensure that it covers the viral genotype of the infected patients.

Abstract
Abstract
Background
Viral hepatitis is the seventh leading cause of mortality globally, and half of this mortality is attributed to hepatitis C virus (HCV). Egypt has the highest HCV prevalence worldwide, with an estimated 14.7% of the population being HCV-positive. HCV infection is the primary cause of liver fibrosis, cirrhosis, and hepatocellular carcinoma. Liver fibrosis varies in severity during chronic HCV infection, and 10–20% of chronic hepatitis C (CHC) patients with severe fibrosis develop cirrhosis. The goal of this work was to assess the clinico-demographic predictors of severity of HCV-induced fibrosis in a cohort of Egyptian patients.
Results
A cohort of Egyptian patients with chronic HCV genotype 4a infection showed significant association between severe fibrosis stages and obesity, represented by a higher body mass index (BMI), low albumin level, high alpha-fetoprotein (AFP) level, low thyroid-stimulating hormone (TSH) level, and high alkaline phosphatase (ALP) level. Multivariate analysis delineated BMI, TSH, and ALP as independent significant variables that could predict the risk of fibrosis severity in HCV infections.
Conclusion
This study argues in favor of using the biomarker profile of CHC patients infected with HCV genotype 4a to identify patients at higher risk of developing severe fibrosis, which is a necessary first step towards precision medicine via patient stratification.

Abstract
Vitamin D supplementation with standard treatment yielded positive clinical outcomes in mild and moderate atopic dermatitis; however, the potential benefit of vitamin D in severe cases remains unclear. This study aimed to evaluate the impact of vitamin D supplementation on response to standard treatment in pediatrics with severe atopic dermatitis. The patients were randomized to receive either vitamin D 3 1600 IU/day or placebo, plus baseline therapy of topical 1% hydrocortisone cream twice daily for 12 weeks. The primary endpoints were the change in mean Eczema Area and Severity Index (EASI) score at the end of the study and the mean percent change in EASI score from baseline to week 12. Eighty-six subjects completed the study. The treated group achieved a significant higher level of 25 hydroxy vitamin D (P < .001) compared to control group at week 12. The mean EASI score was significantly lower in the treatment group compared to placebo group (P = .035). The percent change in EASI score from baseline differed significantly between the supplementation (56.44 ± 29.33) and placebo (42.09 ± 19.22) groups after intervention (P = .039). Vitamin D supplementation could be an effective adjuvant treatment that improves the clinical outcomes in severe atopic dermatitis.

Abstract
BACKGROUND Hepatitis B and C viruses are leading causes of liver cirrhosis and hepatocellular carcinoma (HCC). Toll-like receptor 7 (TLR-7) has been implicated in the pathogenesis of HCC linked to hepatitis B. We hypothesised a role of leukocyte TLR-7 mRNA in hepatitis C related liver cirrhosis and HCC, using alpha-fetoprotein (AFP) and liver function tests as comparators. METHODS We recruited 102 patients with HCV-related HCC, 97 with HCV-related liver cirrhosis and 60 healthy controls. Quantification of TLR-7 mRNA was performed using real-time PCR, AFP and routine LFTs by standard techniques. RESULTS TLR-7 mRNA levels were significantly lower in HCC patients compared to cirrhotic patients and lower again in healthy controls (p < 0.001 for trend). In multivariate analysis, age, aspartate transaminase (AST), AFP, and TLR-7 mRNA were significant predictors of HCC. The ROCC/AUC for age, AST and TLR-7 mRNA were all between 0.64 and 0.78 (all P < 0.01), but for AFP was 0.57 (95% CI 0.48-0.65, P = 0.09). We derived an index score using age, AST and TLR-7 mRNA for the diagnosis of HCC. The ROCC/AUC for the index was superior to all three root indices in the prediction of HCC. The index linked significantly with the Tokyo and Vienna liver cancer staging systems, but not with those of the CLIP and Okuda systems, in distinguishing HCC from liver cirrhosis. CONCLUSION The combination of TLR-7 mRNA levels with age and AST improves the performance of TLR-7 in HCC diagnosis, out-performs alpha-fetoprotein and predicts early HCC.

Abstract
BACKGROUND Gestational diabetes mellitus (GDM) is a serious health problem associated with both foetal and maternal complications. New biomarkers that can predict or help in the early diagnosis of GDM are needed to minimize the hazards of hyperglycaemia in pregnant women and their offspring. We hypothesised a link between levels of microRNA-223 (miRNA-223) and Angiopoietin-Like Protein 8 (ANGPTL8) and GDM. MATERIALS AND METHODS The study included 109 patients with confirmed early diagnosed GDM and 103 healthy control pregnant women in their second or third trimester. miRNA-223 and ANGPTL8 blood levels were assessed by real-time RT-PCR and sandwich ELISA, respectively, laboratory markers by standard methods. RESULTS There was a significant increase in mean [SD] miRNA-223 and ANGPTL8 in GDM (0.31 [0.06] relative units) and (692 [199] pg/ml), respectively, in the GDM women compared to healthy pregnant women (0.17[0.05] relative units) and (261 [127] pg/ml), respectively, P < 0.001. miRNA-223 and ANGPTL8 correlated significantly with each other (r = 0.38, P < 0.001) and with fasting, 1-h and 2-h postprandial blood glucose levels (all P ≤ 0.002) HbA1 c (P < 0.025), total cholesterol (P < 0.01), LDL-C and triglycerides (both P ≤ 0.005). The ROC area under curve (AUC) (95%CI) was 0.94 (0.91-0.97) for ANGPTL8, 0.92 (0.88-0.96) for miRNA-223 and 0.97 (0.95 - 0.99) for their combination. CONCLUSIONS These findings support the hypothesis of involvement of both miRNA-223 and ANGPTL8 in the pathogenesis of GDM. The difference between levels in GDM patients and in control pregnant women indicates potential use for early diagnosis or prediction of GDM.

Abstract
Background: Chronic spontaneous urticaria (CSU) is a common skin disorder affecting negatively patients' lives. Vitamin D deficiency has been reported to be associated to many allergic skin disorders.Objective: This study aimed to evaluate the association between the serum level of 25 hydroxy vitamin D and CSU and to assess the efficacy and safety of active vitamin D in management of CSU.Methods: The study was conducted on 77 patients with CSU and 67 healthy controls, then the 77 CSU patients were randomized to either the study group that received 0.25 µg alfacalcidol daily or the placebo group that received oral placebo for 12 weeks.Results: Serum 25(OH) D was significantly lower in CSU as compared to healthy controls and was negatively correlated to the urticarial severity. After alfacalcidol administration, the study group showed significant higher level of 25(OH) D compared to the placebo group. In addition, the mean serum level of IL6, hsCRP and TNFα significantly decreased in the study group in comparison to the placebo group and as compared to their baseline results.Conclusion: Vitamin D deficiency is more common in CSU patients as compared to healthy people and hence, alfacalcidol might have a beneficial role as add on therapy in CSU management with no reported side effects.

Abstract
Acne vulgaris is one of the most common chronic inflammatory skin disorder affecting millions of people worldwide. Vitamin D deficiency has a role in various inflammatory skin diseases as acne. This study aimed to investigate the serum level of 25 hydroxy vitamin D in acne patients and to assess the efficacy and safety of active vitamin D in management of acne. This study was conducted on 100 patients with acne and 100 healthy controls, then the 100 acne patients were randomized to either the study group that received 0.25ug alfacalcidol daily or the placebo group that received oral placebo during the 3 months study period. Serum levels of 25-hydroxy-vitamin D were significantly lower in acne patients than in healthy control and were inversely correlated to the severity of acne. After alfacalcidol administration, the study group showed significant higher level of 25(OH) D levels (p < .05) compared to placebo group. In addition, median serum level of IL6 and TNFα significantly decreased (p < .05) in the study group in comparison to placebo group and as compared to their baseline results. Acne patients are more commonly to have vitamin D deficiency as compared to healthy people and hence, alfacalcidol might have a beneficial role in the acne management with no reported side effects.

Abstract
Millet flour (water washed or alkali washed) was replaced with wheat flour (WF) at 0, 25, 50, 75, and 100% levels. Objectives of the research were to characterize the flour blends for their technical properties and to produce cookies with less or no gluten contents. All types of flour blends were evaluated for their pasting properties. The cookies were baked and evaluated for their textural and physical attributes. Inclusion of millet flour (both types) in wheat flour resulted in significant reduction in peak and final viscosities while setback viscosities were affected non-significantly. Pasting temperature was increased from 65 ℃ (100% wheat flour) to 91 ℃ (100% millet flour). The hardness of cookies was reduced in the presence of millet flour. Fracturability values of cookies with higher millet flour were higher as compared to control cookies (prepared from 100% wheat flour). Cookies prepared from blends having more that 50% millet flour were not much liked by sensory panelists. The phenolic contents of cookies containing higher levels of either water washed or alkali washed millet flour were found to be higher when compared to cookies prepared from plain WF (1.90 ± 0.14 mg gallic acid/g sample). The 2,2-diphenyl-1-picrylhydrazyl activity (%) of cookies ranged from 16.39 ± 0.34 (100% water washed millet flour) to 10.39 ± 0.26 (100% WF; control).

Abstract
BACKGROUND Vitamin D is a regulatory factor for immunity and skin barrier functions. It is hypothesized to be linked to atopic dermatitis (AD) which is characterized by interaction between epidermal barrier dysfunction and dysregulation of skin immune functions. METHODS One hundred AD patients and one hundred and one normal controls were collected from outpatient clinic based on their clinical condition, both had measurement of 25-hydroxyvitamin D [25(OH)D]. We assessed the relationship between 25(OH)D deficiency and AD prevalence using adjusted Poisson regression model. RESULTS Serum 25(OH)D levels were significantly lower in cases than controls (mean 35.1 versus 22.6 ng/mL, p < .001). The unadjusted prevalence ratios (PRs) (95% CI) for AD for comparing participants with intermediate and deficient vitamin D levels to those with optimal levels were 3.11 (1.91, 5.06) and 4.77 (2.99, 7.60), respectively. The association did not materially change after adjusting for potential confounders. In the fully adjusted analysis stratified by gender, PRs for AD for comparing male participants with intermediate and deficient vitamin D levels to those with optimal levels were 3.38 (1.21, 9.40) and 5.20 (1.91, 14.13), respectively, whereas in the female participants were 1.32 (0.96, 1.83) and 1.49 (1.04, 2.14), respectively (p-interaction <.001). CONCLUSION In this case-control study in children, we found a statistically significant dose-response association between vitamin D deficiency and AD. We also observed a statistically significant effect modification of this association by gender. Further research is recommended to study this association longitudinally, and to examine whether treating vitamin D deficiency may potentially improve AD. Key points Question: Can atopic dermatitis be associated with vitamin D deficiency? Finding: Serum 25(OH)D levels were significantly lower in cases with AD than in controls. Prevalence ratios for comparing male participants with intermediate and deficient vitamin D levels to those with optimal levels were 3.38 (1.21, 9.40) and 5.20 (1.91, 14.13), respectively, whereas in the female participants were 1.32 (0.96, 1.83) and 1.49 (1.04, 2.14), respectively (p-interaction <.001). Meaning: vitamin D deficiency is associated with AD in children, effect modification of this association by gender was also observed.

Abstract
Introduction: Adiponectin is anti-inflammatory and anti-tumor cytokine secreted exclusively from adipocytes. There
is a growing evidence of association between adiponectin gene polymorphism and development of pancreatic cancer.
The current study aimed at evaluation of the possible association between selected adiponectin gene polymorphism and
the risk of pancreatic cancer. Methods: Prospective case-control study included 77 patients (29 women and 48 men)
with biopsy-proven pancreatic adenocarcinoma and 97 healthy control. Blood samples from all included participants
were genotyped for 3 single nucleotide polymorphism (SNPs) of adiponectin genes (rs1501299C>A, rs266729C>G and
rs2241766G>T) by PCR. Clinical, biochemical, and radiological data analyzed. Results: We demonstrated a significant
association between the three studied SNPs (rs1501299, rs266729, and rs2241766) and increased risk of pancreatic
adenocarcinoma (p<0.001). Furthermore, in clinical correlation analysis, Patients with rs2241766 polymorphism
have a lower frequency of lymph node involvement (p 0.05). Smoking and older age were independent predictors of
pancreatic adenocarcinoma. Conclusion: We provided evidence that variants in adiponectin gene might influence the
development and progression of pancreatic cancer.

Abstract
BACKGROUND Licensure of ledipasvir/sofosbuvir for chronic hepatitis C virus (HCV) infection in adolescents was based on clinical trials on patients mainly with genotype 1. We aimed to evaluate the effectiveness and short-term safety of this newly approved antiviral in adolescents with HCV genotype 4. METHODS This was a study of 51 HCV-infected adolescents, who received the adult dose of ledipasvir/sofosbuvir, once daily for 12 weeks, and were followed-up for 12 weeks post-treatment. Laboratory tests, quantitation of HCV RNA, HCV genotyping, IL-28rs gene polymorphism and transient elastography were performed at baseline. Follow-up visits were done for blood testing and adverse events recording. RESULTS The mean age was 14.7 ± 1.5 years (11-17.5), with a male to female ratio of 1.7:1. All patients were genotype 4a, and 76.5% had the CC IL-28 gene polymorphism. About 50% gave a history of HCV-infected mother, and 31% were treatment-experienced. Liver stiffness was F0 in 72.5%, F0-F1 in 13.7% and F1-F2 in 13.7%. Adverse events were mainly abdominal pain in 72.5%, headache in 64.7% and diarrhea in 53% of patients; these were mild. A reversible increase in creatinine level with a concomitant decline in estimated glomerular filtration rate was observed in the first month of treatment. By the end of week 12, a significant decline in liver enzymes was observed. All patients achieved an early, end of treatment, and a sustained virologic response. CONCLUSIONS Adolescent patients with genotype 4 chronic HCV infection achieved a good response rate with good ontreatment tolerability for ledipasvir/sofosbuvir therapy.

Abstract
The current study was aimed to evaluate the protective effect of Holothurian atra (HA) extract; naturally occurring marine resource, against methotrexate (MTX) induced testicular dysfunction. Mature rats received either MTX (20 mg/kg, intraperitoneally) or saline on the 7th day of experiment al design. Seven days prior and after MTX-injection, rats received HA at dose of 300 mg/kg intragastrically (HA + MTX group; HA group alone). Serum was extracted and testicular tissues were examined for the changes in serum biochemistry (liver & kidney biomarkers, testicular hormones and antioxidants), molecular and histopthological alterations using RT-PCR and immunohistochemistry. MTX-injected rats induced alteration in all testicular parameters. Prior administration of HA ameliorated the MTX-induced oxidative stress. HA administration normalised MTX-induced decrease in serum levels of interleukin-6 (IL-6), tumour necrosis factor alpha (TNF-α), interferon-gamma (IFN-γ), reproductive hormones (FSH, LH and testosterone) and antioxidants GST, SOD and catalase. MTX-injected rats down-regulated mRNA expression of GST, SOD, steroidogenesis associated genes, IFN-γ, Bcl2 and NFKB. MTX up-regulated BAX expression and caspase 9 immunoreactivity that were ameliorated in HA + MTX group. Collectively, HA ameliorated and restored all altered genes. In conclusion, HA is a promising supplement that is helpful in protection against testicular cytotoxicity and dysfunction induced by methotrexate.

Abstract
Cryptosporidiosis has been identified as a significant underlying cause of morbidity and mortality worldwide. Studies in high and low income countries have recognized the importance of Cryptosporidium as a cause of diarrhea. The objectives of the current study were to determine the prevalence rate and genotypes of Cryptosporidiumin in diarrheic children in Makkah Region. A total of 1,380 fecal samples were collected from children aged up to 14 years attending 3 major hospitals of Makkah between March 2015 and March 2016. Stool collected were subjected to direct microscopic examination and crypto antigen detection using ImmunoCard STAT, Cryptosporidium/Giardia rapid test. Part of each positive stool sample was kept frozen at -20ºC for molecular characterization. Initial screening by immunochromatographic detection kit revealed 23 positive cases. PCR was performed for positive cases by amplification of a piece of the gene encoding the small (18S) subunit of rRNA producing a 435-438 bp product. Cryptosporidium genotyping was performed by RFLP analysis of PCR products. Genotyping revealed 18 cases C. hominis genotype, 4 cases C. parvaum genotype and one sample failed to be amplified. The data revealed a higher incidence of the common human species C. hominis (81.8%). The detection of both C. hominis and C. parvaum genotypes point to the possibility of both anthroponotic and zoonotic transmission routes occurring in Makkah region. Further studies are needed to verify the subgenotypes of Cryptosporidium to elucidate the real transmission modes and hence plan for effective control strategies.

Abstract
AIM To assess the role of some circulating miRNAs (miR-23a, miR-203, miR338, miR-34, and miR-16) as tumor markers for diagnosis of hepatocellular carcinoma (HCC).
METHODS One hundred and seventy-one subjects were enrolled, 57 patients with HCC, 57 patients with liver cirrhosis (LC) and 57 healthy subjects as control group. Severity of liver disease was assessed by Child Pugh score. Tumor staging was done using Okuda staging system. Quantification of Micro RNA (miR-23a, miR-203, miR338, miR-34, and miR-16) was performed.
RESULTS All studied miRNA showed significant difference between HCC and cirrhotic patients in comparison to healthy control. miR-23a showed statistically significant difference between HCC and cirrhotic patients being higher in HCC group than cirrhotic. miR-23a is significantly higher in HCC patients with focal lesion size equal or more than 5 cm, patients with multiple focal lesions and Okuda stage III. At cutoff value ≥ 210, miR-23a showed accuracy 79.3% to diagnose HCC patients with sensitivity 89.47% and specificity about 64.91%. At cut off level ≥ 200 ng/mL, serum alpha fetoprotein had 73.68% sensitivity, 52.63% specificity, 43.75% PPV, 80% NPV for diagnosis of HCC.
CONCLUSION MicroRNA 23a can be used as a screening test for early detection of HCC. Also, it is related to larger size of tumour, late Okuda staging and multiple hepatic focal lesions, so it might be a prognostic biomarker.

Abstract
A new approach for removal of indigo carmine blue (IC) dye which is extensively used in jeans manufacture was successfully performed on novel mesoporous [LDH] nanoparticles prepared by sol-gel route using CTAB as shape and pore directing agent. The physicochemical features were monitored by X-ray diffraction (XRD), Fourier transformer infra-red (FTIR), N2 adsorption-desorption isotherm, Field emission electron microscope (FESEM) and high resolution transmission electron microscope (HRTEM). The influence of reaction parameters affecting dye adsorption including contact time, initial dye concentration, pH and temperature were investigated. Textural analysis and HRTEM images indicate the existence of mesoporous spherical nanoparticles of size = 26 nm connected to each other's and embedded large numbers of mesopores of average pore radius = 43.5 Å. A successful adsorption of IC on LDH nanoparticles of surface area = 85.6 m2/g at various pH with maximum adsorption capacity = 62.8 mg/g at pH = 9.5. Langmuir model is more favorable to describe the adsorption of IC rather than Freundlich model which reflecting the preferential formation of monolayer on the surface of LDH. Both film diffusion and the intraparticle diffusion affect the dye adsorption. The values of enthalpy change (ΔH) for and (ΔS) are + 28.18 and + 0.118 kJ/mol, respectively indicating that the removal process is endothermic. The results indicated that LDH nanoparticles conserved a good activity even after five consecutive cycles of reuse. Our results suggest that mesoporous LDH nanoparticles are considered a potential novel adsorbent for remediation of wastewater containing IC.

Abstract
Background The growing obesity pandemic is the leading cause for increasing prevalence of nonalcoholic fatty liver disease (NAFLD) in children. Histopathological evaluation of the liver remains the gold standard for NAFLD diagnosis, but it is an invasive procedure with a low but real risk of morbidity and mortality. The current study evaluated circulating chemerin and adiponectin as possible noninvasive diagnostic markers for NAFLD in obese non-diabetic children. Methods A prospective case-control study was conducted, which included 101 obese children with biopsy-proven NAFLD and 57 age- and sex-matched controls. The overall mean age of the children was 10.08±3.12 years. All underwent a full clinical assessment, routine laboratory investigation, and abdominal ultrasound. Homeostatic model assessment-insulin resistance was calculated and circulating chemerin and adiponectin were evaluated using ELISA. Results Elevated serum chemerin and decreased serum adiponectin were significantly associated with an increased likelihood of exhibiting NAFLD. Receiver operator characteristic curve analysis for differentiation of NAFLD patients from those in the control group demonstrated that chemerin, at a cutoff value of 186.7 ng/mL, yielded a sensitivity and specificity of 56.44% and 87.72% respectively (P<0.001), whereas adiponectin, at a cutoff value of 2.4 µg/mL, had a sensitivity and specificity of 74.26% and 3.51% respectively (P<0.001). Furthermore, body mass index, aspartate transaminase, alanine transaminase, triglycerides, and gamma-glutamyl transferase had significant positive correlations with chemerin and significant negative correlations with adiponectin (P≤0.001). Conclusion Circulating chemerin and adiponectin could serve as simple noninvasive diagnostic markers for NAFLD in non-diabetic obese children.

Abstract
OBJECTIVE To evaluate the efficacy of intrathecal dexmedetomidine at improving the quality of the operative field, and prolonging the duration of sensory block, motor block, and postoperative analgesia during spinal surgery PATIENTS AND METHODS This prospective, double-blinded, randomized controlled study included 52 patients undergoing an instrumented one-level posterolateral lumbar spine fusion for lumbar spondylolisthesis under spinal anesthesia. The patients were randomized into two groups: group D (n = 26) received 15 mg of hyperbaric bupivacaine with 5 μg of dexmedetomidine, while group P (n = 26) received 15 mg of hyperbaric bupivacaine only. The operative field quality score, blood loss volume, and the surgeon's satisfaction with the procedure were recorded. The onset time of the sensory block, time to reach peak sensory level, sensory and motor regression times, time to the first requirement of analgesia, sedation level, hemodynamics, and all postoperative complications were also recorded. RESULTS The operative field quality and the surgeon's satisfaction scores (rated excellent) were significantly better in group D than in group P (p < 0.0001 and p = 0.003, respectively). Patients in group D had significantly longer sensory and motor regression times than patients in group P (p < 0.0001). The time to the first requirement of analgesia and the total dose of ketorolac was significantly longer and smaller, respectively, in group D than in group P (p < 0.0001). CONCLUSIONS Intrathecal bupivacaine-dexmedetomidine improved the quality of the operative field, prolonged the duration of the sensory and motor block, prolonged postoperative analgesia, and produced minimal side effects.

Abstract
Hepatitis C virus (HCV) is a global challenge; 130-175 million are chronically infected. Over 350000 die each year from HCV. Chronic HCV is the primary cause of cirrhosis, hepatocellular carcinoma (HCC), and end-stage liver disease. Management of chronic HCV is aimed at preventing cirrhosis, reducing the risk of HCC, and treating extra hepatic complications. New treatments for chronic HCV has been devoted based on direct-acting antivirals, as pegylated interferon (peginterferon) is responsible for many side effects and limits treatment access. Sofosbuvir is the first compound to enter the market with Peginterferon-free combination regimens.

Abstract
BACKGROUND/AIM Vitamin D has been shown to play an important immunomodulatory role. Deficiency of vitamin D has been recently associated to the lack of response to interferon therapy in Hepatitis C virus genotype 1 infected patients. This study aims to evaluate serum level of vitamin D and verify whether circulating vitamin D has any independent role in predicting the rates of HCV virologic response after the administration of pegylated interferon to Egyptian patients infected with genotype 4 HCV. METHODS Fifty patients infected with HCV genotype 4 and not co-infected with neither Hepatitis B virus nor Human Immunodeffiency Virus were recruited for the study. They were treated with ribavirin-pegylated interferon alpha 2a. Viral titer was determined at baseline, at 12 weeks and at end of treatment (48 weeks). Vitamin D levels and a biochemical profile were obtained for the patients at baseline and at end of treatment. Vitamin D control group consisting of 20 healthy patients of similar age and weight to the study group were recruited to obtain vitamin D levels. RESULTS Vitamin D levels in HCV infected patients were significantly lower than in healthy subjects. Responders to ribavirin plus pegylated interferon alpha 2a therapy had significantly higher vitamin D levels than non-responders. CONCLUSION Vitamin D deficiency predicts an unfavorable response to interferon-based treatment of HCV.

Abstract
UNLABELLED Acute myeloid leukemia (AML) describes a heterogenous group of hematological disorders. Cytogenetic and molecular assays have allowed patients' follow up aiming for detection of minimal residual disease, prediction of patients' outcome, in addition to providing the rationale for designing novel molecular-targeted therapeutic strategies. Human telomerase reverse transcriptase (hTERT), encoded by the hTERT gene and the telomerase RNA component (hTERC) genes are frequently amplified in human tumors, which may indicate that the hTERT and the hTERC genes may be target for amplification during the transformation of human malignancies including hematological malignancies. This genetic event has implications in diagnosis, prognosis and therapeutics of cancer. To evaluate the hTERC and hTERT genes as a prognostic marker in patients with AML, hTERC and hTERT gene amplification was studied in 20 adult AML patients using a commercial FISH probes (Kreatech) designated to detect the copy numbers of the genes. They were 12 males and 8 females. Their ages ranged from 16 to 67 years. The patients were further divided into two groups; group I (12 patients) includes newly diagnosed AML patients and group II (8 patients) includes patients taken at 28th day of chemotherapy. The hTERC amplification was detected in 19/21 cases (90.5%). The copy number of the gene ranged from 2-5 copies per interphase cell. For the hTERT gene, the amplification was found in the same percent of the patients. The copy number of the gene ranged from 2-9 copies per interphase cell. On comparing the group I with group II there was a highly statistical significant difference regarding the percent of amplification of both genes. The percent of amplification of hTERT gene was found to be higher among patients with poor outcome of the disease than in patients with good outcome. On the contrary the hTERC gene amplification did not exhibit such a correlation. In conclusion, hTERT and hTERC genes amplification were detected in patients with AML; therefore telomerase can be a good cancer marker which may be involved in carcinogenesis of leukemia. Higher amplification was found in de novo cases than cases in remission which emphasize its role in clinical analysis, disease monitoring and detection of minimal residual disease. KEYWORDS Acute Myeloid leukemia, telomerase amplification, hTERC gene, hTERT gene.

Abstract
Mitral regurgitation (MR) is defined as the loss of the smooth and adequate trimming closure of the mitral valve, which results in the reflux of blood from the left ventricle into the left atrium during systole. The functional competence of the mitral valve relies on the proper and coordinated interaction of the following structures: the mitral annulus, and leaflets, chordate tendineae, papillary muscles, left atrium and the left ventricles. This article will describe the echocardiography assessment of the mitral valve regurgitation with special emphasis on the trans-esophageal and 3D echocardiography. The echocardiography images were all original with special attention to the unique surgical view of the images.

Abstract
Echocardiography plays a major role in diagnosis, etiology and severity of Mitral Stenosis (MS), analysis of valve anatomy and decision-making for intervention. This technique has also a crucial role to assess consequences of MS and follow up of patients after medical or surgical intervention. In this article we review the role of conventional echocardiography in assessment of mitral stenosis and future direction of this modality using 3D echocardiography.

Abstract
This study was carried out in a governmental school for mentally disabled children in El Minia. We assessed maternal adaptation and the relationship between maternal sociodemographic factors and adaptation as well as examining maternal distress. All 100 mothers with children aged 6-18 years attending the school were recruited in the study. Three tools were used: demographic data sheet, adaptation scale to assess the nature of mothers' interaction and patterns of psychosocial adaptation and depression scale to detect the presence of psychiatric disorders among the mothers. Only 35.0% of the mothers adapted positively to their child's condition; 62.9% of those had female children. Negatively adapted mothers were slightly older than positively adapted mothers and had more children. Maternal education and occupation were significantly associated with psychosocial adaptation. Knowledge of mothers about their child's condition significantly affected adaptation as well as the dependency of children in eating, drinking and sleeping. Two-thirds of mothers had high levels of psychopathology.

Abstract
Gene fusions prevalent in prostate cancer (CaP) lead to the elevated expression of the ERG proto-oncogene. ERG activation present in 50–70% of prostate tumors underscores one of the most common oncogenic alterations in CaP. Despite numerous reports of gene fusions and mRNA expression, ERG oncoprotein status in CaP still remains to be defined. Furthermore, development of ERG protein-based assays may provide a new dimension to evaluation of gene fusions involving diverse androgen-regulated promoters and the ERG protein-coding sequence. Through exhaustive evaluations of 132 whole-mount prostates (261 tumor foci and over 200 000 benign glands) for the ERG oncoprotein nuclear expression, we demonstrated 99.9% specificity for detecting prostate tumor cells using a highly specific anti-ERG monoclonal antibody. The ERG oncoprotein expression correlated well with fusion transcript or gene fusion in randomly selected specimens. Strong concordance of ERG-positive foci of prostatic intraepithelial neoplasia (PIN) with ERG-positive carcinoma (82 out of 85 sections with PIN, 96.5%) affirms the biological role of ERG in clonal selection of prostate tumors in 65% (86 out of 132) of patients. Conversely, ERG negative PINs were associated with ERG-negative carcinoma. Taken together, the homogeneous and strong ERG expression detected in individual tumors establishes the potential for ERG oncoprotein-based stratification of CaP.

Abstract
OBJECTIVES To provide information about preventive measures and treatment seeking behaviour as well as an estimate of the malaria burden in different epidemiological settings for effective monitoring and evaluation of the ongoing efforts. METHODS Cross-sectional survey carried out in four areas representing different levels of transmission to explore the use of preventive measures, care-seeking behaviour and accessibility in addition to point prevalence was followed by a follow-up phase in which the health workers registered and reported all fever cases including malaria. The relation between the reported malaria incidence, the product of symptomatic/asymptomatic ratio and the prevalence of confirmed malaria cases was used to develop the equation that could predict the true malaria incidence. RESULTS Thousand households and 3628 individuals were surveyed. The presence of any net varied between 6.6% and 40%; the percentage of people who reportedly slept under mosquito nets in the previous night varied between 35 and 80. Prompt use of medications ranged between 14 and 48% with a delay of more than 24 h noticed in different areas. The mean number of individuals per household who reported use of anti-malarial drugs in the last 2 weeks ranged between 0.6 (SD = 0.92) and 1.2 (SD = 1.1), with variable cost per treatment and affordability. The prevalence of asymptomatic parasitaemia, fever and confirmed malaria at time of the survey differed by area. The incidence of malaria during the follow-up period was estimated to be 8.5, 178.6, 23.7 and 10.3 episodes per 1000 population in Malakal, Elrank, Elhosh and El Matama, respectively. Based on this, a prediction equation was developed. CONCLUSION We found suboptimal health care seeking behaviour, coverage and use of preventive measures with a high malaria burden. We developed a model for future estimation of malaria episodes.
