Prognostic impact of human papillomavirus infection on cervical dysplasia, cancer, and patient survival in Saudi Arabia: A 10-year retrospective analysis.

Background: Data on human papillomavirus (HPV) prevalence and survival rates among HPV-infected women are scarce in Saudi Arabia.

Objective: Assess the prevalence of HPV genotypes in cervical biopsy specimens and its effect on survival over a 10-year timeframe.

Design: Retrospective, cross-sectional.

Virus sensing receptors in cellular infectivity of influenza A virus.

An innate immune response is essential to mobilize protective immunity upon the infection of respiratory epithelial cells with influenza A virus (IAV). The response is classified as early (nonspecific effectors), local systematic (effector cells recruitment) and late (antigen to lymphoid organ transport, naive B and T cells recognition, effector cells clonal expansion and differentiation). Virus particles are detected by the host cells as non-self by various sensors that are present on the cell surface, endosomes and cytosol.

Human papillomavirus epidemiology in populations with normal or abnormal cervical cytology or cervical cancer in the Middle East and North Africa: A systematic review and meta-analysis.

Background: Human papillomavirus (HPV), one of the most common sexually transmitted viral infections worldwide, is the leading cause of cervical cancer. In Middle East and North Africa (MENA) Region HPV data is at scarce, and most of the countries haven't implemented any vaccination programs. This present meta-analysis and systematic review aimed to describe human papillomavirus (HPV) epidemiology by clinical subgroups in the (MENA) region.

Development of a Simple, Fast, and Cost-Effective Nanobased Immunoassay Method for Detecting Norovirus in Food Samples.

This study presents a quick, low-cost, and easy technique for the detection of norovirus in several food samples, including cucumber, lettuce, and chicken. The developed sandwich immunoassay method depends on employing nanotechnology for the detection step. Lactoferrin immobilized on activated Q-tips cotton swabs was used as a general capturing reagent to bind viruses from the sample surface.

Human papillomavirus type 16 and 18 viral loads as predictors associated with abnormal cervical cytology among women in Saudi Arabia.

The detection of HPV viral DNA is regularly conducted with cervical screening. However, using a molecular marker such as the viral load may serve as a predictor associated with disease detection and progression. The present study aimed to screen for and genotype HPV among women in Saudi Arabia, develop and validate sensitive quantitative polymerase chain reaction (qPCR) assays to detect viral load for the two most common HPV types, namely 16 and 18, and assess whether HPV viral load could be used as a marker for cervical abnormality and disease progression.
