Objective: To investigate the effects of sex disparities on clinicopathological characteristics and prognosis of 3937 Chinese gastric cancer (GC) patients.Materials and methods: A total of 3937 Chinese patients, including 3098 males (78.7%) and 839 females (21.3%), diagnosed with GC at the General Hospital of Ningxia Medical University of China were selected through inclusion and exclusion criteria, and the prognosis of the patients was followed up. Clinicopathological features were assessed, and univariate and multivariate survival analyses were performed.Results: The ratio of male to female was approximately 3.7:1. Compared to females, male patients were relatively older and had more cigarette smoking and alcohol consumption history, higher percentage of late-stage GC, more proximal tumors, and better differentiation of cancer (p<0.05). There was no significant difference between the male and female patient groups in terms of the cumulative overall survival rate (62.1% vs. 64.8%), 1-year survival rate (69.7% vs. 71.6%), 3-year survival rate (46.6% vs. 48.5%)and 5-year survival rate (20.8% vs. 15.8%). Female patients with cigarette smoking history and male patients in stage IV or without treatment had a poorer prognosis (p&...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.
