Abstract
The welding ability of Ti-6Al-4V alloy is weak due to their two-phase microstructure. On the other hand, friction welding methods lead to significant microstructural changes. In this research, for the first time, pure titanium was successfully joined to the Ti-6Al-4V alloy, without any change in the microstructure and mechanical properties of both alloys, by applying the SPW method. Further, the effects of temperature, pressure, and time of the SPW process on the microstructure and mechanical properties of commercial pure (C.P) titanium joined to the Ti-6Al-4V alloy were investigated. The results indicated that the effect of temperature and pressure on the SPW process was greater than that of time. Further, mechanical properties investigations showed that the yield strength of the joint interface was larger than that of the substrate metal, following which necking and fracture occurred in the pure titanium substrate metal. The alloy (Ti-Ti64) bonded at 800 °C, with a time of 10 min and pressure of 20 MPa, exhibited the superior bonding of 7-9 μm interface thickness, and excellent tensile strength (534 ± 13 MPa) and Vickers micro-hardness (190 ± 5 HV0.1). Investigation of the effect of pressure (normal stress) also showed that with an increase in pressure, because of the reduction of the chemical potential of diffusing species, the joint temperature would drop, and the joint could be created at a temperature below 800 °C.

Abstract
BACKGROUND Scleredema adultorum of Buschke is a rare disease characterized by firm and non-pitting edema of the skin. The condition is rare with unknown etiology. Diagnosis is made on the basis of clinical findings and skin biopsy. CASE PRESENTATION Here, we describe a 14-year-old Iranian girl presenting with non-pitting edema and woody thickening of the skin that progressed within a month. She was evaluated for possible underlying malignancy or connective tissue disorders, which were excluded by multiple laboratory workups. She underwent a skin biopsy which confirmed the diagnosis of scleredema, and she was successfully treated with intravenous immunoglobulin and mycophenolate mofetil. CONCLUSION While scleredema adultorum of Buschke is a rare disease with no definite treatment, our effort through this report was to highlight the possible benefits of treatment by intravenous immunoglobulin and mycophenolate mofetil.

Abstract
Seborrheic keratosis is a common benign epidermal lesion that typically occurs in the elderly population. Its occurrence in childhood and adolescence is rare and can pose a diagnostic challenge for clinicians and dermatopathologists. We report a case of a 16-year-old boy with multiple brown, black oval-shaped stuck-on lesions on his face, which were diagnosed as seborrheic keratosis based on histological findings. The patient had no significant medical history or family history of seborrheic keratosis. In this report, we discuss the differential diagnoses of seborrheic keratosis-like lesions in childhood and adolescence and explain why they were not compatible with our case. We also review the available treatment options. Our case emphasizes the need for dermatologists to consider seborrheic keratosis in the differential diagnosis of cutaneous lesions in young patients.

Abstract
Oncocytoma is a common benign kidney tumor. The size is often less than 5 cm. Oncocytomas may be misdiagnosed in clinic, radiology and histopathology for renal cell carcinoma. Different panels of immunohistochemistry (IHC) are suggested in the renal tumors with eosinophilic granular cytoplasm including oncocytoma, chromophobe and clear renal cell carcinoma. Here we report a large oncocytoma in a 64-year-old lady, that the mimickers ruled out by IHC.

Abstract
Background: Amplification of HER2 is an important factor in the diagnosis and treatment of breast cancer. Fluorescence in situ hybridization (FISH) is the gold standard for the detection of HER2-positive tumors. However, the Immunohistochemistry (IHC) assay for the detection of HER2 is more popular in the preclinical laboratory since it is faster and more economical compared to the FISH test. Materials and Methods: In this study, the status of HER2 amplification is determined by the FISH test using 44 formalin-fixed paraffin-embedded tissue samples and comparing the results with the IHC test to determine the reliability of the IHC test. Also, the relationship between HER2 amplification and estrogen, progesterone receptors, P53, age, menopausal status, family history of breast cancer, tumor size, and histological grade were determined. Results: Examination of HER2 in 44 samples by IHC showed 3 (6.8%) and 5 (11.4%) samples were positive (IHC 3+) and negative (IHC 0, 1+), respectively, and 36 (81.8%) samples were ambiguous (IHC 2 +), but examination by FISH showed 21 samples (47, 7%) were positive and 23 samples (52, 3%) were negative. There was a significant difference between IHC and FISH in the detection of HER2 amplification (P=0.019). Also, there was a significant difference between HER2 amplification and menopause in patients (P=0.035). Conclusion: This result demonstrated that the IHC test is not a reliable test to determine HER2 amplification. This study represented that FISH analysis is more reliable than IHC and must be preferentially performed for all cases, especially for HER2 +2 cases for whom the IHC result is 2+.

Abstract
Nowadays, academics have paid special attention to global warming, because it has several issues such as urban heat island (UHI) related to the quality of life. For this purpose, a spatial decision support system (SDSS) has been developed to investigate the effect of parcels' roof covering type on surface heat island (SHI) values and its variation at the neighborhood scale in Tehran, Iran. This SDSS, as the innovation of the present research, consists of two main steps including estimating the UHI value in the study area and adopting the optimum set of parcels to change their roofs' cover with three types of vegetation, high-albedo material, and flagstone. The first step is accomplished by aggregating various indices related to land cover obtained from Landsat 8 images. The aggregation is done by linear regression method (LRM) with an RMSE and R2 equal to 0.942 and 0.897, respectively. Then, the genetic algorithm was used to select the optimal subset, including 10% of the parcels in the area, to change their roof covering type based on minimizing the UHI's variation. The standard deviation obtained after the changes improved from 13.222 to 10.781 °C. The results indicate that to control UHI in the center of the region, it is necessary to inhibit UHI effects at the boundary of the study area with vegetation roof covering since flagstone and high-albedo materials have local effects on controlling the UHI effects.

Abstract
Background Thyroid cancer is the most common endocrine malignancy. Studies have observed an anti-cancer effect for vitamin D and found that polymorphisms of vitamin D receptors can influence the prevalence of various cancers. The present study investigated the serum level of vitamin D and FokI, BsmI and Tru9I polymorphisms of vitamin D receptors. Methods Forty patients with medullary thyroid cancer and 40 healthy controls were investigated. The genomic DNA of the subjects was extracted using saturated salt/proteinase K and investigated by PCR sequencing. Serum levels of vitamin D were evaluated by ELISA. The results were analyzed in SPSS and GraphPad Prism 5 software. Results The genotypic and allelic frequencies of FokI and BsmI polymorphisms showed no significant differences between test and control groups. For Tru9I polymorphism, Tt genotype and t allelic frequency in the test group were significantly different from those of the control group. Also, we found Tt genotype and t allelic frequency to be significantly associated with medullary thyroid cancer (MTC) type and the agressiveness of the disease. The average serum vitamin D level was 23.32 ng/mL and 18.95 ng/mL for patients and controls, respectively, and the difference between the two groups was statistically significant. Moreover, we found high serum vitamin D level to be associated with t allelic frequency. Conclusions Unexpectedly, the mean serum vitamin D level of the test group was significantly higher than that of the control group. Tru9I polymorphism was found to be significantly correlated with the prevalence of medullary thyroid carcinoma.

Abstract
Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) uses the angiotensin-converting enzyme 2 (ACE2) receptor of SARS-CoV for cell entry. We aimed to check the association between ACE2 and COVID-19 (coronavirus disease 2019) in a systematic review. Two databases (PubMed/Medline and Scopus) and bioRxiv were checked for retrieving all types of studies in relation to ACE2 and COVID-19 until March 18, 2020. Forty-one studies were entered to the systematic review. These studies included nineteen original, eight reviews, four letters to the editor, three research papers, one correspondence, one commentary, one mini review, two reports, one opinion, and one perspective. In summary, the results showed that the ACE2 receptor for COVID-19 is similar to that of SARS-CoV. However, its expression was different in various populations as well as in the two genders. ACE2 may be used as a therapeutic target. Patients who take ACE inhibitors may have benefit in severe disease outcomes. Finally, pangolins and snakes and turtles may act as the potential intermediate hosts transmitting disease to humans.

Abstract
Abstract
Background
Polycystic ovary syndrome (PCOS) is the most common endocrinopathy affecting women. The purpose of this study is to evaluate the effects of Stachys sylvatica hydroalcoholic extract on biochemical and histological parameters in a rat model of polycystic ovary syndrome. Thirty adult female Wistar rats with an average weight of 180 g were divided into five groups of six rats. Animals were divided into groups of control, PCOS (intramuscular injection of 2 mg estradiol valerate, Aburaihan Co., Iran/rat, once), and treated with hydroalcoholic extract of Stachys sylvatica. After 60 days of PCOS induction, 100, 250, and 500 mg/kg BW Stachys sylvatica hydroalcoholic extract were injected intraperitoneally. The control group was just injected with olive oil as a solvent. After 10 days of treatment, animals were weighed and then sacrificed and blood samples were taken from their heart for hormonal studies. Ovaries of all groups were cut for histological studies and fixed in formaldehyde, and 7-μm sections were prepared by microtome and stained using hematoxylin–eosin. The data were analyzed by one-way ANOVA and Tukey-Kramer post hoc test with the SPSS software. The significant level was p < 0.05.
Results
The Stachys sylvatica extract can improve obesity in the PCOS group. The histological and hormonal results showed that PCOS induction can decrease the number of preantral, antral, and Graafian follicles as well as corpus luteum in comparison with the control (p < 0.001), whereas the number of cystic follicles increased significantly (p < 0.001). After treatment with Stachys sylvatica hydroalcoholic extract (500 mg/kg), a significant increase was observed in all these parameters. In addition, the number of cystic follicles decreased significantly (p < 0.001). The level of LH and FSH hormones decreased significantly (p < 0.01) in the PCOS group compared with the control. In contrast, the estrogen level increased significantly (p < 0.01). In the 250 and 500 mg/kg group, treatment with the extract could increase FSH and decrease estrogen concentration significantly relative to the PCOS group (p < 0.01). Results of antral follicle morphometry indicated an increase in follicle diameter and theca thickness, but the thickness of the granulosa layer decreased significantly. An improvement in these measurements was observed in the treated PCOS groups with all doses.
Conclusions
It can be concluded that Stachys sylvatica hydroalcoholic extract can improve some symptoms of polycystic ovary syndrome because of components such as iridoids, flavonoids, and sesquiterpenes with antioxidant and anti-inflammatory effects. In this experiment, 500 mg/kg dose of extract was considered as the most effective dose.

Abstract
BACKGROUND Psoriasis has a complex genetic background with a strong heritable component. Herein, the present meta-analysis aims to evaluate the association of ERAP1 polymorphisms with psoriasis susceptibility. METHODS PubMed, Web of Sciences, Scopus, and Cochrane Library databases were examined with no time limits up to March 2019, without language, age, and sex restrictions. The odds ratio (OR) and 95% confidence interval (CI) were calculated by CMA 2.0 software in a dichotomous analysis using computed effect sizes and having OR and confidence limits for each study. The subgroup analysis based on ethnicity, type of study, and genotyping method was performed. RESULTS Thirteen articles were involved in the meta-analysis, in details eight were cohort studies and five were case-control studies. The results showed an association between rs27524 [OR = 1.179; 95%CI: 1.081, 1.286; p < 0.001] and rs30187 [OR = 1.237; 95%CI: 1.133, 1.351; p < 0.001] polymorphisms and psoriasis susceptibility; whereas no association was detected with rs26653 [OR = 1.013; 95%CI: 0.798, 1.286; p = 0.914] and rs27044 [OR = 1.164; 95%CI: 0.982, 1.381; p = 0.080] polymorphisms. Psoriasis susceptibility in both Caucasian and Asian ethnicities was related to rs27524 polymorphism, while rs30187 and rs27044 polymorphisms were over-represented in patients belonging to Caucasian ethnicity. In addition, in cohort studies, psoriasis susceptibility was related to rs27524 polymorphism, while the associated polymorphisms were rs26653 and rs27044 in case-control studies, and rs30187 in both cohort and case-control studies. CONCLUSIONS These findings showed an association between rs27524 and rs30187 polymorphisms and susceptibility to psoriasis, while lack of association was obtained for rs26653 and rs27044 polymorphisms. In order to confirm our results, further studies are needed, also considering different factors, such as type of psoriasis and ethnicity.

Abstract
BACKGROUND Psoriasis is a multifactorial disorder, impacted by both genetic and environmental factors. Herein, a meta-analysis assessed the association of angiotensin-converting enzyme gene insertion/deletion (ACE I/D) polymorphism and psoriasis susceptibility. METHODS A systematic search was used in databases of PubMed/Medline, Scopus, Web of Science, and Cochrane Library up to January 2019 without language restriction. A dichotomous analysis was carried out by RevMan 5.3 using crude odds ratio (OR) and 95% confidence interval (CI) to investigate the association between ACE I/D polymorphisms and the risk of psoriasis. A funnel plot analysis was used by CMA 2.0 to estimate a significant existence of publication bias. RESULTS Out of 61 studies retrieved from the databases, 16 studies were included in the meta-analysis. The pooled ORs for models of D vs. I, DD vs. II, ID vs. II, ID + DD vs. II, and DD vs. II + ID genotypes were 0.96 [95%CI: 0.82, 1.12; P = 0.58], 0.99 [95%CI, 0.73, 1.36; P = 0.96], 0.81 [95%CI, 0.72, 0.91; p: 0.0003], 0.91 [95%CI, 0.73, 1.13; P = 0.40], and 1.05 [95%CI, 0.85, 1.30; P = 0.68], respectively. A significant difference between ACE polymorphisms in patients with/without family history for the disease [OR = 1.44; 95%CI: 1.24, 1.67; P < 0.001] and also in patients mild/severe psoriasis [OR = 0.70; 95%CI: 0.55, 0.88; P = 0.002] was identified. CONCLUSION The results of the meta-analysis showed that ACE I/D polymorphism may be associated with psoriasis susceptibility, while ID genotype seemed to have a protective role in Caucasian patients affected by psoriatic arthritis and in studies with hospital-based controls.

Abstract
Abstract
Background: Meningiomas consist of 15%–30% of the primary intracranial tumors, and high-grade meningiomas have a higher recurrence after surgery. The human epidermal growth factor receptor 2 (HER2) status is important in the medical management of patients with various human cancers. This study aimed to evaluate HER2 expression in meningiomas and the correlation between this expression and age, gender, and grade. Materials and Methods: In a descriptive-analytic study, immunohistochemistry (IHC) with HER2 marker was done on confirmed cases of meningioma which were referred to the pathology laboratory from 2008 to 2015. The primary antihuman antibody against c-erbB-2 oncoprotein (DAKO Diagnostics) was used for IHC. Results: Of 117 patients, 68.4% were males. The mean age of the patients was 53.6 years. Grades I, II, and III tumors were 90.6%, 8.5%, and 0.9% of cases, respectively. Totally, 76 (65%) of patients were HER2 positive, with only 7.7% of highly expressed HER2. There was no significant correlation between the mean age (P = 0.672), age group (P = 0.256), sex (P = 0.574), and grade (P = 0.093) and HER2 expression status. Conclusions: We did not find a statistically significant correlation between age, sex, or grade and HER2 status; however, further studies with a higher number of Grades II and III meningiomas and using the fluorescent in situ hybridization in equivocal cases may be of benefit in this way.

Abstract
Agrobacterium rhizogenes-mediated transformation of sugar beet hairy roots expressing single-chain variable fragment (scFv) was exploited to evaluate the efficacy of four antibody-based constructs for interfering with the Beet necrotic yellow vein virus infection. The scFv specific to a major coat protein of virus, p21, was targeted to various cellular compartments including the cytosol (pIC and pICC constructs), apoplast (pIA), and mitochondrion (pIM). After mechanical virus inoculation, most of the hairy root clones expressing scFv in the cytosol displayed low virus titers while the majority of transgenic hairy root clones accumulated antibody in outer membrane of mitochondria or apoplast were infected. This hairy root system provided an efficient and rapid approach to initially investigating root disease resistance like rhizomania prior to transform whole recalcitrant plants such as sugar beet.

Abstract
Pulmonary alveolar microlithiasis (PAM) is a rare disease with autosomal recessive inheritance. Herein, a 20-year-old lady referred to the hospital with a dry cough for two years. The chest X-ray findings were bilateral reticulonodular opacities in both lungs and honeycomb appearance suspicious for miliary tuberculosis and idiopathic pulmonary fibrosis. A wedge biopsy of lung showed that there were several intraalveolar laminated concretions in the pathology report compatible with pulmonary alveolar microlithiasis and interstitial infiltration of lymphocytes and neutrophils compatible with interstitial pneumonitis. PAM is a rare progressive disease with the production of microliths in pulmonary alveoli. The pathologist, radiologist, and clinician should be familiar with this entity for diagnosis and appropriate management. The family of the patient especially siblings must be evaluated for earlier diagnosis.

Abstract
BACKGROUND Psoriasis is the prime example of psoriasiform tissue pattern and should be differentiated from other psoriasiform dermatoses both clinically and histopathologically. AIM To evaluate immunohistochemical expression of P53, Ki-67, and CD34 in psoriasis and psoriasiform dermatitis for diagnostic purposes. METHODS An analytical cross-sectional study was performed on the paraffin blocks of 60 psoriasis and 31 psoriasiform dermatitis patients between 2014 and 2017. The selected formalin-fixed paraffin-embedded tissues from each biopsy specimen were cut into 4-micron sections. Initial sections were stained by hematoxylin and eosin staining. Primary antihuman antibodies against P53, Ki-67, and CD34 were applied. Positive control samples for biomarkers were received from former strongly positive samples of papillary endothelial hyperplasia, high grade lymphoma, and breast ductal carcinoma for CD34, Ki-67, and P53, respectively. RESULTS Out of 60 psoriasis patients, 56.7% were men, with the mean age of 36.8 years. From 31 psoriasiform patients, 45.2% were men, with the mean age of 37.5 years. Both groups were matched in terms of sex and age. The mean staining of three markers was more significant in psoriasiform dermatitis than psoriasis. CONCLUSION In spite of some other researches, the present study showed expression of P53, Ki-67, and CD34 biomarkers were significantly higher in psoriasiform dermatitis than psoriasis.

Abstract
INTRODUCTION Rhinophyma is an uncommon subtype of rosacea, the clinical diagnosis of which is straightforward. However, localized, especially well-circumscribed, rhinophyma is a very rare condition, which requires a paraclinical assessment to be accurately diagnosed. CASE REPORT We report a 48-year-old male patient who presented with a well-circumscribed and dark red tumoral mass of 28 mm in diameter and smooth consistency in the right nasal ala. The patient had no former and concomitant characteristic skin lesions on the other part of his face. Histopathology and immunohistochemistry assessments documented the diagnosis of rhinophyma. CONCLUSION To the best of our knowledge, this is the first case report of well-circumscribed localized rhinophyma. This lesion can be treated by CO2 laser in a fast and efficient manner with esthetically satisfactory outcome and no significant complications.

Abstract
Background and objective: Cortisol, as the main human glucocorticoid, is considered to be a biological marker of stress and anxiety. Since it is known that oral lichen planus (OLP) can appear and worsen during stressful events, cortisol levels have been previously studied in OLP patients. The present meta-analysis aims to assess the salivary concentration of cortisol in OLP patients compared to healthy controls. Materials and methods: Web of Science, PubMed, Cochrane Library, and Scopus databases were searched up to October 2018. The RevMan 5.3 software was used with the mean difference (MD) and 95% confidence intervals (CIs). The CMA 2.0 Software was used to evaluate the publication bias, sensitivity analysis, and meta-regression as possible sources of heterogeneity. Results: 10 studies were analyzed and a total of 269 OLP patients and 268 controls were included. The pooled MD of the salivary levels of cortisol in OLP patients compared with controls was 4.27 ng/mL (95% CI: 2.33, 6.21; P < 0.0001), thus, the salivary level of cortisol in OLP patients was significantly higher than in controls. In Indian-based population studies, a significant difference in the salivary cortisol levels in OLP patients compared with controls was detected (MD = 5.62 ng/mL; 95% CI: 2.67, 8.56; P = 0.0002). In addition, a significant difference in the salivary cortisol levels in the OLP patients compared with the controls was obtained in studies performed with enzyme-linked immunosorbent assay (ELISA) method (MD = 5.33 ng/mL; 95% CI: 2.72, 7.93; P < 0.0001). Conclusion: We suggest that supportive psychological treatment together with the conventional therapy could increase patients' capability to prevent stress, anxiety, and depression.

Abstract
Gastrointestinal (GI) metastasis is very rare in patients with breast cancer (BC). This study reports a case with colon carcinoma metastasis originated from breast cancer in Western Iran. A 37-yearold female was diagnosed with infiltrating ductal carcinoma. Immunohistochemistry (IHC) results showed positive estrogen receptor, progesterone receptor, HER2 scored 2 out of 3, Ki-67 in 30% of tumor cells and P53. The patient was re-admitted two times with urinary and GI symptoms, positive tumor markers and thick colon wall. Samples from the colon were collected to test for metastasis. The pathologist reported metastatic breast ductal carcinoma spread to the colon. The IHC showed CK7, CK20, GCDFP15, ER and PR positivity. In conclusion, this IHC panel can be considered as the differential and diagnostic markers for malignant GI lesion originated from breast cancer.

Abstract
Chromophobe renal cell carcinoma (RCC) is a rare type of kidney neoplasm that is diagnosed in the 6th decade of life with similar incidence in male and female. We reported a case of 73-year-old man with a chief complaint of nocturia, frequency, dribbling and urinary retention with renal mass in ultrasound examination. Histologic examination and immunohistochemistry study revealed the diagnosis of chromophobe RCC which initially was mistaken for oncocytoma in frozen section diagnosis. The pathologist should be aware of this malignant entity and be cautious in diagnosing oncocytoma in frozen section and routine H & E staining.

Abstract
Background: Saliva is a fluid with the complex compound which can be used as diagnostic markers for type 2 diabetes (T2D). This meta-analysis evaluated salivary glucose, immunoglobulin A (IgA), total protein, and amylase levels in adult T2D compared with the controls as well as the correlation of salivary glucose levels with serum glucose and hemoglobin A1C (HbA1c) levels in both groups. Materials and Methods: Web of Science, Scopus, PubMed, and Cochrane Library databases were searched up to July 2017. A random-effects analysis was performed using the mean difference (MD) and 95% confidence intervals. The search terms were “T2D, IgA, amylase, total protein, or glucose” combination with “saliva.” The studied variables were the sample size, the percentage of male, the mean age, the condition of saliva sampling, and the salivary levels of mentioned factors. Results: A total of 25 studies were included in this meta-analysis with 1432 and 900 diabetic patients and healthy controls, respectively. MD of salivary glucose level in patients with T2D, compared with the healthy controls, in fasting and nonfasting conditions were 6.23 mg/dL (P = 0.0002) and 6.70 mg/dL (P < 0.00001), respectively. Furthermore, the fasting salivary total protein in the patients was significantly higher than the controls (MD = 167.96 mg/dL; P = 0.03). Non-fasting salivary amylase and secretory IgA levels were significantly lower in the patients (MD = −48.61 IU/mL; P < 0.00001) than in the controls (MD = −9.42 IU/mL; P = 0.0006), respectively. The pooled estimate showed a significant correlation between salivary and serum glucose in the patients (r = 0.765; P < 0.001) and the controls (r = 0.646; P < 0.001) and between salivary glucose and serum glycated hemoglobin in the patients (r = 0.721; P < 0.001). Conclusion: Measurement of these salivary factors can be helpful for diagnostic and monitoring purposes of T2D. In addition, salivary glucose as a diagnostic tool can evaluate serum glucose and HbA1c levels in the diabetic patients.

Abstract
AIM OF THE STUDY This meta-analysis evaluated serum interleukin-6 (IL-6) levels in hepatocellular carcinoma (HCC) patients compared with healthy controls and hepatitis and cirrhotic patients. MATERIAL AND METHODS The three databases PubMed, Scopus, and Web of Science were searched for assessment of IL-6 levels in HCC patients (without cirrhosis and hepatitis) compared with healthy controls (without HCC, cirrhosis and hepatitis) and the studies were selected based on inclusion and exclusion criteria. A random-effect meta-analysis was performed with RevMan 5.3 software, using mean difference (MD) and 95% confidence intervals (CIs). RESULTS Out of 503 studies searched in databases, 18 studies were included in the meta-analysis. The pooled analysis with continuous data demonstrated that the IL-6 level in HCC patients was significantly higher than that in healthy controls (MD = 12.44; 95% CI: 9.02-15.85; p < 0.00001). Also, the pooled analysis demonstrated that the IL-6 levels in cirrhotic patients (MD = -6.98; 95% CI: -12.91-1.05; p < 0.02) and patients with hepatitis (MD = -8.43; 95% CI: -11.91-4.95; p < 0.00001) were significantly lower than the level in HCC patients, and the subgroup analyses had high heterogeneity. CONCLUSIONS The elevated IL-6 levels in HCC patients compared with hepatitis and cirrhosis patients and healthy controls may show a significant association of this cytokine with increased risk of HCC and its potential as a diagnostic marker for HCC in future diagnostic and therapeutic strategies.

Abstract
A fluctuation relation for the heat exchange of an open quantum system under a thermalizing Markovian dynamics is derived. We show that the probability that the system absorbs an amount of heat from its bath, at a given time interval, divided by the probability of the reverse process (releasing the same amount of heat to the bath) is given by an exponential factor which depends on the amount of heat and the difference between the temperatures of the system and the bath. Interestingly, this relation is akin to the standard form of the fluctuation relation (for forward-backward dynamics). We also argue that the probability of the violation of the second law of thermodynamics in the form of the Clausius statement (i.e., net heat transfer from a cold system to its hot bath) drops exponentially with both the amount of heat and the temperature differences of the baths.

Abstract
As a prophylactic cancer vaccine, human amniotic membrane epithelial cells (hAECs) conferred effective protection in a murine model of colon cancer. The immunized mice mounted strong cross-protective CTL and antibody responses. Tumor burden was significantly reduced in tumor-bearing mice after immunization with hAECs. Placental cancer immunotherapy could be a promising approach for primary prevention of cancer. In spite of being the star of therapeutic strategies for cancer treatment, the results of immunotherapeutic approaches are still far from expectations. In this regard, primary prevention of cancer using prophylactic cancer vaccines has gained considerable attention. The immunologic similarities between cancer development and placentation have helped researchers to unravel molecular mechanisms responsible for carcinogenesis and to take advantage of stem cells from reproductive organs to elicit robust anti-cancer immune responses. Here, we showed that vaccination of mice with human amniotic membrane epithelial cells (hAECs) conferred effective protection against colon cancer and led to expansion of systemic and splenic cytotoxic T cell population and induction of cross-protective cytotoxic responses against tumor cells. Vaccinated mice mounted tumor-specific Th1 responses and produced cross-reactive antibodies against cell surface markers of cancer cells. Tumor burden was also significantly reduced in tumor-bearing mice immunized with hAECs. Our findings pave the way for potential future application of hAECs as an effective prophylactic cancer vaccine.

Abstract
Oral mucositis (OM) is one of the most common side effects after hematopoietic stem cell transplantation (HSCT) and palifermin is used for prophylactic use to prevent OM. We conducted a meta-analysis study that evaluates the efficacy of palifermin on OM after HSCT in hematologic malignancy patients. Databases of PubMed/Medline, Web of Science and Cochrane Library for English-language publications were searched for finding the relevant studies. The RevMan 5.3 software with random-effects models (odds ratio (ORs) and 95% confidence intervals (CIs)) was used for to estimate of the efficacy of palifermin in palifermin group compared with control group. Begg's and Egger's tests were used for assessment of bias between the studies. Ten studies were included in the meta-analysis study. The results of the meta-analyses showed that there were significant differences in OM (grade 1-4) [odds ratio (OR) = 0.17; 95%CI= 0.10,0.29; p <0.00001], OM (grade 2-4) [OR= 0.11; 95%CI= 0.05,0.24; p <0.00001], OM (grade 3-4) [OR= 0.22; 95%CI= 0.15,0.33; p <0.00001], after auto-HSCT for OM (grade 1-4) [OR= 0.13; 95%CI= 0.04, 0.35; p <0.0001], OM (grade 2-4) [OR= 0.03; 95%CI= 0.00, 0.21; p =0.0006] or OM (grade 3-4) [OR= 0.25; 95%CI= 0.13, 0.48; p <0.0001], after allo-HSCT for OM (grade 1-4) [OR= 0.23; 95%CI= 0.11, 0.51; p =0.0002], OM (grade 2-4) [OR= 0.14; 95%CI= 0.03, 0.74; p =0.012] or OM (grade 3-4) [OR= 0.19; 95%CI= 0.08, 0.46; p =0.0002] and fever [OR=0.51; 95%CI=0.29, 0.87; p = 0.01], but there were no significant differences in acute graft versus host disease (aGVHD) grades, infection and blood stream infection between two groups. The meta-analysis showed that palifermin was associated with reductions in the incidence and severity of OM and also was effective and safe on OM after allo- or auto-HSCT, but did not seem to effect on the incidence and severity of aGVHD.

Abstract
OBJECTIVE Tumor necrosis factor-α (TNF-α) has a role in the progression of the oral lichen planus (OLP). The aim of this meta-analysis study was to evaluate the salivary and serum TNF-α levels in patients with OLP. STUDY DESIGN We searched in the databases of PubMed/Medline, Science direct, Scopus, Web of Science, and Cochrane Library for studies reported from 1983 to 2016. All studies were checked for evaluation of salivary and serum levels of TNF-α in patients with OLP compared with healthy controls. RESULTS Twelve studies were included in the meta-analysis. The mean difference of 7 studies reporting salivary TNF-α levels in patients with OLP versus healthy controls was 25.90 pg/mL (95% confidence interval [CI] 15.31-36.49; P < .00001) and 7 studies reporting serum TNF-α levels was 1.65 pg/mL (95% CI -0.82 to 4.11; P = .19). CONCLUSIONS In patients with OLP, the higher levels of TNF-α in saliva compared with serum suggest that measurement of this marker in saliva may be more useful than in serum for determining diagnostic and therapeutic aims.

Abstract
Background Although many factors are involved in the etiology of xanthelasma palpebrum,
lipid disorder is strongly associated with its induction. Xanthelasma
palpebrum, the most common type of xanthoma, usually presents in middle-aged
females and results in aesthetic problems. Objective To evaluate thelipid profile and important clinical aspects of xanthelasma
palpebrum patients. Methods In this descriptive study, we enrolled 42xanthelasma palpebrumpatients, and
42 cases of non-inflammatory skin disorders as thecontrol group, matched for
age and gender.The clinical characteristics of the patients and fasting
serum lipid profile were recorded for both groups. The data obtained were
analyzed using SPSS-16. Results Xanthelasma palpebrum was found more commonly in middle-aged females with
disease onset of less than 1 year, and without significant familial history
of xanthoma. Furthermore,xanthelasma lesionswere most often seen in the
upper lid with mild extension and was rarely associated with systemic
disease. There was no statistically significant difference between two
groups regarding hypertriglyceridemia (p= 0.231) and hypercholesterolemia
(p= 0.302). The mean serum levels of cholesterol (221.51±60.4 mg/dl),
triglyceride (185.98±71.1 mg/dl) and VLDL (37.7±17.6 mg/dl)
were significantly higher and themedian HDL (36.2 (31, 41) mg/dl) level was
lower in thepatient group. Conclusion In our study, hypercholesterolemia and hypertriglyceridemia did not reveal a
significant difference between thepatient and control groups; however, mean
serum values for cholesterol, triglyceride, VLDL and HDL showed a
significant difference between the two groups. Therefore, in addition to
lipid abnormality, other factors could be involved in the pathogenesis of
xanthelasma palpebrum.

Abstract
Background: Salivary gland tumors are rare head and neck tumors with lymphoepithelial carcinoma (LEC) as a particularly infrequent variant. This study was an evaluation of the incidence of EBV infection in malignant salivary gland tumors with the emphasis on tumor type and geographical area. Methods: Five databases (PubMed, ScienceDirect, Scopus, Web of Science and Cochrane library) were searched for data on the prevalence of EBV in malignant salivary gland tumors. A random-effects meta-analysis was conducted with Comprehensive Meta-Analysis software version 2.0 (CMA 2.0) using the event rate (ER) for estimation of the incidence of EBV in the salivary gland tumor patients. Publication bias was lacking as assessed through funnel plot analysis with the Begg’s and Egger’s tests (P>0.05). Results: Out of 618 studies searched in databases, 19 reported the prevalence of EBV in malignant salivary gland tumors and were included in the present meta-analysis. The pooled ER of all studies was 44% [95%CI=21.5-69.2%] with extreme heterogeneity that for the studies in America was 44.2% [95%CI=4.1-93.6%], in Asia (249 patients) was 70% [95%CI= 33.4-91.6%] and in Europe was 11.8% [95%CI=7.4-85.5%] with extreme heterogeneity for three subgroups. The pooled ER for patients with undifferentiated carcinoma was 86.7% [95%CI=71.5-94.4%] compared with 6.6% [95%CI=2.5-16.5%] for other carcinomas. Conclusions: The incidence of EBV infection in malignant salivary gland tumors in Asia was greater than in Europe and America and the higher presence of EBV infection in LEC cases implies that EBV may be a major factor in its etiology or pathogenesis. Genetic, environmental and other geographic factors may also be involved.

This article reports on the synthesis and full characterization of innovative silica-based nanoparticle composed of fumed silica as a core decorated with polyethylenimine (PEI) with different molecular weights (25, 10 and 1.8 kDa). Wide range of analytical, spectroscopic, and microscopic methods (TEM, DLS, ζ potential, elemental analysis (EA), TNBS and FTIR) were used to characterize the nanoparticles. Furthermore, transfection efficiency of these nanoparticles as non-viral vector was examined. The silica-PEI conjugates retained both the ability of PEI to fully condense plasmid DNA at low N/P ratios and suitable buffering capacity at the endosomal pH range. PEI-functionalized silica remarkably enhanced EGFP-N1 gene expression in murine neuroblastoma (Neuro-2A) cells up to 38 folds compared to PEI 25 kDa. Meanwhile the results of the cytotoxicity assays indicated that these silica-PEI conjugates have acceptable level of viability.

Abstract
BACKGROUND Basal and squamous cell carcinoma (BCC and SCC) are the most common skin cancers worldwide and distinction between the two may sometimes be very difficult in routine histopathology. The present study was aimed to evaluate a reliable diagnostic method for these cancers based on immunohistochemistry (IHC). MATERIALS AND METHODS IHC was used with antibodies to Bcl-2, CD10, CEA, and EMA biomarkers, which despite non-specificity are easily available for detection of various types of tumors in pathology sections and can be used as a panel for differentiation. In this descriptive and analytic study, paraffin- embedded blocks of 29 SCC patients and 29 BCC patients were collected and sectioned for IHC staining. The results were analyzed by the STATA (version 8) statistical package using the Chi-square test. RESULTS BCC patients were 100%, 75.8%, 0% and 0% positive for Bcl-2, CD10, CEA and EMA markers, respectively, and for SCC patients were 3.5%, 0%, 34.5% and 82.7% positive, respectively. Using simultaneously Bcl-2 and CD10 as positive markers, detection of BCC with 88% accuracy and 100% specificity was possible, while application of CEA and EMA positivity could detect SCC with 67% accuracy and 100% specificity. CONCLUSIONS SCC and BCC have different immunostaining profiles; therefore, Bcl-2, CD10, CEA and EMA markers can be helpful to distinguish between them.

Abstract
BACKGROUND Androgen receptors (ARs) are expressed in more than 70% of breast cancers (BCs) and have been implicated in BC pathogenesis. Some triple negative (TN)BC tumors express AR and may benefit from ARtargeted therapies. The aim of this study was to evaluate survival and the prevalence of AR expression and its correlation with other risk factors in triple negative BCs in women from Western Iran. MATERIALS AND METHODS In a retrospective study between 20092015, 41 patients with TNBC were referred to the Private Clinic of Oncology, Kermanshah city, Iran. ER, PR and ARpositive expression was defined as ≥10% nuclear staining and also HER2 (2+), FISH was performed. Nuclear staining was considered representative for Ki67 and P53. The mean followup for the patients was 25 months. In this time, 5 patients died and 4 lost to followup were censored from survival analysis. RESULTS The mean age at diagnosis was 46.9 years (range, 2471 years) and all patients were female. The OS rates for ARpositive and ARnegative patients were 90% and 85.1%, respectively, and the mean OS was 26.3 and 23.2 months. Therefore, there was no significant difference between the two groups (Hazard ratio: 0.580, 95% CI: 0.0863.893, P=0.575). CONCLUSIONS In TNBC patients, evaluation of AR status may provide additional information on prognosis and treatment. The results of studies showed that the prevalence AR expression may differ in the world and probably ethnicity can be an influencing factor.

Abstract
AIM Diazinon (DZN) is one of the most important organophosphorus compounds used to control pests in agriculture in many countries. Several studies have shown that exposure to DZN may alter protein expression in the liver. In order to further investigate the mechanism of DZN toxicity, differentially expressed ATP-interacting proteins, following subacute exposure to toxin, were separated and identified in rat liver. MAIN METHODS Male rats were equally divided into four groups: control (corn oil) and DZN (15 mg/kg) by gavage once a day for 4 weeks. After homogenization of liver tissue, lysates were incubated ATP-sepharose beads. After several washes, ATP-interacting proteins were eluted and separated on 2-D polyacrylamide gels. Deferentially expressed proteins were cut and identified using matrix-assisted laser desorption/ionization/time-of-flight and Mascot database. Identified proteins were classified according to their biological process using protein analysis through evolutionary relationships (PANTHER) Web site. KEY FINDING In this work, we showed that several key proteins involved in biological processes such as antioxidant system, oxidative stress, apoptosis, and metabolism were differentially expressed after subacute exposure to DZN.
