The Physical Condition and Mental Health of Chinese College Students 3 Months After COVID-19 Recovery.

The study was to evaluate the physical condition and mental health of Chinese college student COVID-19 survivors, and to perform severity clustering of physical symptoms. The study finally included 1912 Chinese college students. A total of 33 symptoms including general physical symptoms, cardiopulmonary system, digestive system, neurological system, mental health and other symptoms were investigated three months after recovery from COVID-19, and these symptoms are identified using latent class analysis.

Effects of functional defects in the NMD pathway on rice phenotype and transcriptome.

Nonsense-mediated mRNA decay (NMD) is an important RNA quality control pathway. It aids in degrading harmful erroneous mRNA, thereby preserving a stable and healthy internal environment. In this study, we employed CRISPR/Cas9 and amiRNA technology to generate knock out or knock down mutants of realted genes in the rice NMD pathway.

Prediction of positive pulmonary nodules based on machine learning algorithm combined with central carbon metabolism data.

Background: Lung cancer causes a huge disease burden, and early detection of positive pulmonary nodules (PPNs) as an early sign of lung cancer is extremely important for effective intervention. It is necessary to develop PPNs risk recognizer based on machine learning algorithm combined with central carbon metabolomics.

Methods: The study included 2248 participants at high risk for lung cancer from the Ma'anshan Community Lung Cancer Screening cohort.

Targeted metabolomics reveals the association between central carbon metabolism and pulmonary nodules.

With the widespread application of low-dose computed tomography (LDCT) technology, pulmonary nodules have aroused more attention. Significant alteration in plasma metabolite levels, mainly amino acid and lipid, have been observed in patients of PNs. However, evidence on the association between central carbon metabolism and PNs are largely unknown.

[Concurrent Collection of Ammonia Gas and Aerosol Ammonium in Urban Beijing During National Celebration Days Utilizing an Acid-Coated Honeycomb Denuder in Combination with a Filter System].

Since 2013, the Chinese government implemented the Air Pollution Prevention and Control Action Plan. As a result, the atmospheric concentrations of sulfate reduced significantly, whereas the nitrate concentrations remain relatively high due to the excess of ammonia (NH). To date, there is no official observation network monitoring NH concentrations in China.
