Background: Acute myocardial injury is defined by elevated cardiac troponin (cTn) levels with a rising and/or falling pattern, and is associated with increased mortality risk compared to patients without myocardial injury. The role of β-blockers in patients with acute myocardial injury remains unclear.
Methods: This multicenter, retrospective cohort study used data from the Tianjin Health and Medical Data Platform to assess the impact of early β-blocker use on 1-year all-cause mortality and major adverse cardiovascular events (MACE) in acute myocardial injury patients, employing a new user and target trial emulation design.
Urban flooding threatens residents and their property, necessitating timely and accurate flood simulations to enhance prevention measures. However, as a megacity, Shanghai presents a complex underlying surface that proves challenging to assess accurately in existing studies. To simulate the dynamic flooding caused by Typhoon In-Fa in Shanghai from July 23rd to 28th 2021, we employed the LISFLOOD hydrodynamic model with multi-source data and validated the flooded area using the S1FLOOD deep learning model with Sentinel-1 satellite imagery.

It remains unclear how long a CVD patient needs to live to potentially benefit from colchicine. Our study aimed to determine the time to benefit (TTB) of colchicine in individuals with CVD.

The typical inverse gradient-grained structure, which is composed of a hard central layer and a soft surface layer, can be obtained by laser surface heat treatment. A much narrower gradient layer leads to the highest yield strength by sacrificing ductility when the surface temperature of the laser-irradiated region remains at ~850 °C, whereas the fully recrystallized microstructure, which exists from the top surface layer to the ~1.

Prophenoloxidase (PPO) in the midgut of Plutella xylostella is activated by the CLIP domain serine protease (clip-SP) in response to Bacillus thuringiensis (Bt) infection, but the detailed signaling cascade following this activation is unknown. Here, we report that activation of clip-SP enhances PO activity in the P.

Enhanced immune response is an important factor in insect resistance to a variety of insecticides, and whether phenoloxidase (PO), an immune protein, is involved in resistance to Cry1Ac toxin in P. xylostella remains unclear.

The polycalin protein is one of the potential receptors for toxins, and previous studies have confirmed that the Cry1Ac toxin can bind to the polycalin protein of , but whether polycalin is associated with the resistance of toxins remains controversial.

This study intended to screen genes associated with Bt resistance in by comparing the midgut transcriptome of Cry1Ac-susceptible and -resistant strains together with two toxin-treated strains 24 h before sampling. A total of 12 samples were analyzed by BGISEQ-500, and each sample obtained an average of 6.

Plutella xylostella (L.) is a globally distributed lepidopteran pest of cruciferous vegetables and has developed severe field resistance to the Bt toxin.

Acupuncture is a recommended treatment option for stroke by the World Health Organization (WHO) and has been shown to improve the cognitive function of patients with poststroke cognitive impairment (PSCI).
Methods: In the present study, we assessed the efficacy of scalp acupuncture with cluster needling on PSCI patients.
Genistein, a major phytoestrogen of soy, is considered a potential drug for the prevention and treatment of post-menopausal osteoporosis. Mounting evidence suggested a positive correlation between genistein consumption and bone health both in vivo and in vitro. Earlier studies have revealed that genistein acted as a natural estrogen analogue which activated estrogen receptor and exerted anti-osteoporotic effect.
