Background: The lifting of the regional blockade in early December 2022 in Shanxi Province, China, caused an epidemic of Coronavirus disease 2019 (COVID-19). And the high allergy season from July to September each year.
Purpose: To investigate the effect of the COVID-19 epidemic on the respiratory sensitivity status of the population, to provide a scientific and effective basis for the prevention, diagnosis, condition assessment, and treatment of allergic respiratory diseases.
Aim: Ginsenosides have notable bioactivity in treating cardiovascular diseases, but the mechanisms of their combined use with Peroxiredoxin 6 (PRDX6) in myocardial injury remain unclear. This study explores the synergistic effects of Ginsenoside Rb1 (Gs-Rb1) and PRDX6, aiming to provide a theoretical foundation for their therapeutic potential.
Methods: We established a rat model of isoproterenol (ISO)-induced myocardial injury and observed that combination therapy was more effective than single-drug treatments, as shown by ECG monitoring and Masson staining.
Porcine epidemic diarrhea virus (PEDV), a swine enteropathogenic coronavirus, causing acute diarrhea, dehydration, and up to 100 % mortality in neonatal suckling piglets, leading to huge economic losses in the global swine industry. Vaccination remains the most promising and effective way to prevent and control PEDV. In this study, we produced PEDV virus-like particles (VLPs) composed of S, M, and E proteins with a baculovirus expression system and a mammalian expression system.

The required procedure of introducing hydrogen peroxide (HO) directly into the colorimetric reaction systems in traditional biothiols array analysis limits its applicability due to its poor stability and inhibition in biomolecular activity by using the high-concentration HO. Herein, we carried out a "green" and convenient approach to propose for the biothiol detection and disease discrimination through nanozymes-based colorimetric sensor technique without adding the high-concentration HO for the first time.

However, current treatment is limited and does not distinguish different disease stages. Here, we aimed to study the differential functions of Axl, a receptor tyrosine kinase expressing on both macrophages and fibroblasts, in the whole course of pulmonary fibrosis.

There is increasing evidence that astrocytes are the primary targets of A. A can cause abnormal synaptic glutamate, aberrant extrasynaptic glutamate, and astrocytic calcium dysregulation through astrocyte glutamate transporters facing the synaptic cleft (GLT-syn), astrocyte glutamate transporters facing the extrasynaptic space (GLT-ess), metabotropic glutamate receptors in astrocytes (mGluR), N-methyl-D-aspartate receptors in astrocytes (NMDAR), and glutamatergic gliotransmitter release (Glio-Rel).

However, cross-protection between epidemic G2a and G2b subtype strains has not been observed, and there is currently no vaccine against both G2a and G2b strains. In this study, we demonstrate the low cross-protection between G2a and G2b strains with piglet immunization and challenge tests.

Stomata are epidermal openings that facilitate plant-atmosphere gas and water exchange during photosynthesis, respiration and water evaporation. SPEECHLESS (SPCH) is a master basic helix-loop-helix (bHLH) transcription factor that determines the initiation of stomatal development. It is known that blue light promotes stomatal development through the blue light photoreceptor cryptochromes (CRYs, CRY1 and CRY2).

The aim of this study was to investigate sequence variation and recombination events in the spike (S) gene of PEDV isolates from China. Thirty complete S gene sequences were obtained from PEDV-positive samples collected in six provinces in China from 2020 to 2023.

Starting from BTX-A51, a CK1α inhibitor that also targets CDK7 and CDK9, we designed and synthesized a series of 2,4-diaminopyrimidine derivatives as potent CDK7 inhibitors. The representative compound, , displayed significant enzymatic inhibitory activity and demonstrated a remarkable selectivity profile against a panel of kinases, including seven CDK subtypes.

Previous research has examined the microbiota of diarrhetic yaks; however, the structural changes in gut bacterial community and microbial interactions in yaks with grassland alteration-induced diarrhea remain poorly understood. To explore variations in gut microbiota homeostasis among yaks suffering from diarrhea, fecal microbiota diversity and composition were analyzed using 16 S rRNA amplicon sequencing.

We tested the wear loss weight and analyzed the surface morphology of the shoulder surfaces after welding for 200 m. This study found that as the distance between the concave pits decreased and the number of concave pits increased, the maximum downforce, torque, and temperature in the welding process showed a decreasing trend.

DNA addition products (DNA adducts) caused by cigarette smoking are critical factors in its mechanism of carcinogenesis. However, most DNA adducts detected to date in humans cannot be specifically ascribed to smoking but rather have multiple exogenous and endogenous sources.

Chinese pine ( Carr) is an important native timber tree species widely distributed in northern China, but it is unclear exactly where germplasm of the main Chinese pine plantation populations originated. Here, using two mtDNA markers, we analyzed 796 individuals representing 35 populations (matR marker), and 873 individuals representing 38 populations (nad5-1 marker) of the major natural and artificial populations in northern China, respectively (Shanxi, Hebei and Liaoning provinces).
