Incidence and severity of SARS-CoV-2 reinfection, a multicenter cohort study in Shanghai, China.

During March 2022 to January 2023, two Omicron waves hit Shanghai and caused a massive number of reinfections. To better understand the incidence and clinical characteristics of SARS-CoV-2 reinfection in Shanghai, China, we conducted a multicenter cohort study. COVID-19 patients first infected with BA.

Programmed Degradation of Pericarp Cells in Wheat Grains Depends on Autophagy.

Wheat is one of the most important food crops in the world, with development of the grains directly determining yield and quality. Understanding grain development and the underlying regulatory mechanisms is therefore essential in improving the yield and quality of wheat. In this study, the developmental characteristics of the pericarp was examined in developing wheat grains of the new variety Jimai 70.

Zinc in Wheat Grain, Processing, and Food.

Improving zinc (Zn) content in wheat and its processed foods is an effective way to solve human Zn deficiency, which can cause a variety of diseases. This article summarizes the works on Zn in wheat grain, wheat processing, and wheat-derived foods. Grain Zn content in wheat was 31.

Autophagic Survival Precedes Programmed Cell Death in Wheat Seedlings Exposed to Drought Stress.

Although studies have shown the concomitant occurrence of autophagic and programmed cell death (PCD) in plants, the relationship between autophagy and PCD and the factors determining this relationship remain unclear. In this study, seedlings of the wheat cultivar Jimai 22 were used to examine the occurrence of autophagy and PCD during polyethylene glycol (PEG)-8000-induced drought stress. Autophagy and PCD occurred sequentially, with autophagy at a relatively early stage and PCD at a much later stage.

Controlled attenuation parameter for assessment of hepatic steatosis grades: a diagnostic meta-analysis.

Aim: to evaluate the performance and accuracy of Controlled attenuation parameter CAP for hepatic steatosis detection.

Methods: PubMed, EBSCO, Elsevier Science, Ovid, and Wiley were selected to search studies until August 31, 2014. Quality Assessment of Diagnostic Accuracy Studies checklist was used to assess the quality of included studies.

Transcriptome characterization and differential expression analysis of cold-responsive genes in young spikes of common wheat.

With the frequent occurrence of climatic anomalies, spring frost has become a significant limiting factor on wheat production, especially during the reproductive growth stage. A high-throughput sequencing technology was applied and a total of 54 million clean reads that corresponded to 7.44 Gb of total nucleotides were generated.
