Background: Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) can cause repeated infections. China experienced an outbreak of COVID-19 (coronavirus disease 2019) after the Chinese government changed its COVID-19 policy in December 2022. However, little is known about the influencing factors, such as a history of previous infection and vaccine dose, and whether these factors affect the time at which the antigen test results become negative for SARS-CoV-2.

Characterizing the structure and function of cerebral arteries may facilitate the understanding of hypertension-related pathological mechanisms and lead to the development of new indicators for cognitive impairment.
Purpose: To investigate the associations between morphological features of the intracranial arteries distal to the circle of Willis on time-of-flight MRA (TOF-MRA) and cognitive performance in a hypertensive cohort.
The extensive consumption of fossil fuels increases CO concentration in the atmosphere, resulting in serious global warming problems. Meanwhile, the problem of water contamination by organic substances is another significant global challenge. We have successfully synthesized ZnGaTe/g-CN (ZGT/GCN) composites for the first time as effective photocatalysts for both pollutant degradation and CO reduction.

Isothermal studies and MD simulations suggested that MPs have a stronger affinity for aromatic hydrocarbons in seawater. To uncover the mechanism, MPs' surface characteristics and their intermolecular interactions with aromatic hydrocarbons were examined.

Pesticides are extensively used in agricultural production, and their residues in soil, water, and agricultural products have become a threat to aquatic ecosystem. In this study, the toxicity of haloxyfop-p-methyl, an aryloxyphenoxypropionate herbicide was studied using the model animal zebrafish. The development of zebrafish larvae was affected by haloxyfop-p-methyl including spinal deformities, decreased body length, slow heart rate, and large yolk sac area.

AgNbO was characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS), UV-visible diffuse reflectance spectroscopy (DRS), and Brunauer-Emmett-Teller (BET) measurement. The photocatalytic activity of AgNbO was investigated in degradation of sulfamethoxazole (SMX) under visible light, which is a widely used antibiotic with significant threats towards health and aquatic organisms.

Our previous study demonstrated that the KLF5 transcription factor promotes BLBC cell proliferation and tumor growth. In this study, we demonstrated that the histone deacetylase inhibitors (HDACi), suberoylanilide hydroxamic acid (SAHA), and trichostatin A (TSA), increased KLF5 acetylation at lysine 369 (K369), downregulated KLF5 protein expression levels, and decreased cell viability in BLBC cell lines.

Although ambulatory brachial BP is recognized as the most reliable BP measurement in the dialysis population, there is no comparison of office central BP with ambulatory BP regarding risk stratification in these patients.
Methods: In a multicenter prospective study of dialysis patients, central BP was measured noninvasively on a midweek nondialysis day, with interdialytic ambulatory BP and predialysis BP also collected.
