Disease burden of tuberculosis in China from 1990 to 2021 and its prediction to 2036.

Background: Tuberculosis (TB) is one of the oldest infectious diseases and continues to be a major killer of human beings. This paper was designed to provide insights into the disease burden of TB.

Methods: The data was retrieved and downloaded from the latest GBD database.

Current research trends, hotspots, and frontiers of medical nutrition therapy on cancer: a bibliometric analysis.

Background: There is a high prevalence of malnutrition in cancer patients, which seriously affects the anti-cancer therapy effect and outcomes, causing a huge disease burden worldwide. Appropriate nutritional support is important for cancer prevention and control. The aim of this study was to explore the development trends, hotspots, and frontiers of Medical Nutrition Therapy (MNT) on Cancer from a bibliometric perspective, and provide new insights for future research and clinic practices.

Simultaneous measurement of methyl tert-butyl ether and tert-butyl alcohol in human serum by headspace solid-phase microextraction gas chromatography-mass spectrometry.

The abundant production of methyl tert-butyl ether (MTBE) and its widespread use have led to an increase in the potential for human exposure. This work described a simple, fast, sensitive, reliable and low-cost method for the simultaneous measurement of MTBE and its metabolite, tert-butyl alcohol (TBA) in human serum by headspace solid-phase microextraction gas chromatography-mass spectrometry. Extraction conditions were optimized and 40 °C, 10 min, 250 rpm and 0.

Equalization filters for multiple-channel electromyogram arrays.

Multiple-channels of electromyogram activity are frequently transduced via electrodes, then combined electronically to form one electrophysiologic recording, e.g. bipolar, linear double difference and Laplacian montages.
