Salivirus infection: Systematic review and meta-analysis of association with gastrointestinal symptoms in children.

Salivirus (SaV) is a newly described member of the family Picornaviridae that has been associated with gastrointestinal (GI) symptoms, particularly in children. The aim of the present study was to evaluate the prevalence of SaV in symptomatic children and its potential association with GI complications. A systematic search was conducted from 01 December 2009 to 10 December 2020, in three major English databases, including Scopus, PubMed and Web of Science as well as Google scholar search engine.

Possible role of HPV/EBV coinfection in anoikis resistance and development in prostate cancer.

Background: This study aimed to evaluate the possible role of human papillomavirus (HPV) and Epstein-Barr virus (EBV) coinfection as an etiological factor for prostate cancer (PCa) development.

Methods: This case-control study was conducted on 67 patients with PCa and 40 control subjects. The expression levels of cellular and viral factors involved in inflammation, tumor progression, and metastasis were quantified, using the enzyme-linked immunosorbent assay (ELISA) and quantitative real-time polymerase chain reaction (qRT-PCR) assay.

Serum B cell activating factor (BAFF) and sarcoidosis activity.

Objectives: This study aims to determine the relationship between the severity of sarcoidosis and serum B-cell activating factor (BAFF) concentrations.

Patients And Methods: This cross-sectional study was conducted between December 2015 and March 2018 on 55 patients with sarcoidosis (16 males, 39 females; mean age, 39.9; range 25 to 60 years) and 28 healthy subjects (7 males, 20 females; mean age, 39; range 25 to 60 years).

Human papillomavirus and prostate cancer: The role of viral expressed proteins in the inhibition of anoikis and induction of metastasis.

Background: The aim of this study is to address the role of HPV in prostate cancer (PCa) development through the inducement of resistance to anoikis.

Methods: In this case-control study, prostate tissues and blood samples were collected from 116 individuals, including 72 cases with PCa and 44 non-malignant prostate tissue samples as a control group. The expression level of HPV genes (E2, E6, and E7) and cellular genes including anti-apoptotic mediators (Bcl-2 and survivin), tumor suppressor proteins (Rb and p53), and some mediators involved in anoikis resistance and invasiveness (E-cadherin, N-cadherin, Twist, PTPN13 and SLUG) were evaluated.

The role of miR-146a in viral infection.

Cellular microRNAs (miRNAs) were identified as a key player in the posttranscriptional regulation of cellular-genes regulatory pathways. They also emerged as a significant regulator of the immune response. In particular, miR-146a acts as an importance modulator of function and differentiation cells of the innate and adaptive immunity.

Evaluation of STAT3 rs1053004 single nucleotide polymorphism in patients with chronic hepatitis B and hepatocellular carcinoma.

Chronic infection with hepatitis B (CHB) virus is one of the most important risk factors for Hepatocellular carcinoma (HCC). Hepatitis B virus (HBV) causes liver cancer in various ways. One of these ways is increasing the expression of the signal transducer and activator of transcription 3 (STAT3) in Hepatocytes by HBV.
