Increased circulating level of interleukin-6 and CD8 T cell exhaustion are associated with progression of COVID-19.

Background: Coronavirus disease 2019 (COVID-19) is pandemic. It is critical to identify COVID-19 patients who are most likely to develop a severe disease. This study was designed to determine the clinical and epidemiological features of COVID-19 patients associated with the development of pneumonia and factors associated with disease progression.

Study on the correlation between KCNJ11 gene polymorphism and metabolic syndrome in the elderly.

The aim of the study was to examine the correlation between KCNJ11 gene polymorphism and metabolic syndrome in elderly patients. From January 2014 to January 2015, 54 elderly patients with metabolic syndrome were enrolled in this study as the observation group. During the same period, 46 healthy elderly individuals were enrolled in this study as the control group.

Molecular characterization of Tb, a new approach for an ancient Brucellaphage.

Tb (Tbilisi), the reference Brucellaphage strain, was classified as a member of the Podoviridae family with icosahedral capsids (57 +/- 2 nm diameter) and short tails (32 +/- 3 nm long). Brucellaphage DNA was double stranded and unmethylated; its molecular size was 34.5 kilobase pairs.

[Development of a model for the diagnosis and risk classification on anthrax through artificial neural network].

Objective: Based on data through clinical and epidemiological studies, a model regarding the diagnosis and risk classification on anthrax was developed by artificial neural network (ANN). The model could integrally diagnose anthrax cases, judge the risk tendency in time, and increase the ability of recognizing the anthrax accidents.

Methods: Clinical, laboratory and epidemiological data from anthrax cases was collected and analyzed.
