Perceived stress and willingness to quit smoking among patients with depressive and anxiety disorders seeking treatment.

Rationale And Objectives: Little are known about nicotine dependence (ND), perceived stress, and willingness to quit smoking at different treatment stages in patient with affective disorders (AD). This study aimed to evaluate the association between ND and perceived stress among patients with AD presenting with psychiatric treatment at different clinical stages (first visit or follow-up), and in different nicotine type users (cigarette and waterpipe smokers). We also aimed to evaluate the willingness to quit smoking and its association with barriers to quitting.

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.

Human Papillomavirus-Associated Cancers.

Human Papillomavirus (HPV) is the causative agent in the majority of anal, head and neck, oral, oropharyngeal, penile, vaginal, vulvar, and cervical cancers. Cervical cancer is the fourth most common cancer among women worldwide. Of all diagnosed human malignant neoplasms, approximately 4.

Gene Expression and Transcriptome Profiling of Changes in a Cancer Cell Line Post-Exposure to Cadmium Telluride Quantum Dots: Possible Implications in Oncogenesis.

Cadmium telluride quantum dots (CdTe-QDs) are acquiring great interest in terms of their applications in biomedical sciences. Despite earlier sporadic studies on possible oncogenic roles and anticancer properties of CdTe-QDs, there is limited information regarding the oncogenic potential of CdTe-QDs in cancer progression. Here, we investigated the oncogenic effects of CdTe-QDs on the gene expression profiles of Chang cancer cells.

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.
