Metagenomic insight into the diffusion signal factor mediated social traits of anammox consortia after starvation.

Biomass starvation is common in biological wastewater treatment. As a social trait of microbial community, how quorum sensing (QS) regulated bacterial trade-off through interactions after starvation remains unclear. This study deciphered the mechanism of anaerobic ammonium oxidation (anammox) consortia in response to starvation, including reducing extracellular electron transfer (EET), adenosine 5'-triphosphate (ATP) content and amino acid metabolism.

OXCT1 succinylation and activation by SUCLA2 promotes ketolysis and liver tumor growth.

Ketone bodies generated in hepatocytes in the adult liver are used for nonhepatic tissues as an energy source. However, ketolysis is reactivated in hepatocellular carcinoma (HCC) cells with largely unelucidated mechanisms. Here, we demonstrate that 3-oxoacid CoA-transferase 1 (OXCT1), a rate-limiting enzyme in ketolysis, interacts with SUCLA2 upon IGF1 stimulation in HCC cells.

Safety and Intranasal Retention of a Broad-Spectrum Anti-SARS-CoV-2 Monoclonal Antibody SA55 Nasal Spray in Healthy Volunteers: A Phase I Clinical Trial.

Background: A broad-spectrum anti-SARS-CoV-2 monoclonal antibody (mAb), SA55, is highly effective against SARS-CoV-2 variants. This trial aimed at demonstrating the safety, tolerability, local drug retention and neutralizing activity, systemic exposure level, and immunogenicity of the SA55 nasal spray in healthy individuals.

Methods: This phase I, dose-escalation clinical trial combined an open-label design with a randomized, controlled, double-blind design.

SiC MOSFET with Integrated SBD Device Performance Prediction Method Based on Neural Network.

The SiC MOSFET with an integrated SBD (SBD-MOSFET) exhibits excellent performance in power electronics. However, the static and dynamic characteristics of this device are influenced by a multitude of parameters, and traditional TCAD simulation methods are often characterized by their complexity. Due to the increasing research on neural networks in recent years, such as the application of neural networks to the prediction of GaN JBS and Finfet devices, this paper considers the application of neural networks to the performance prediction of SiC MOSFET devices with an integrated SBD.

Unraveling Ferroptosis: A New Frontier in Combating Renal Fibrosis and CKD Progression.

Chronic kidney disease (CKD) is a global health concern caused by conditions such as hypertension, diabetes, hyperlipidemia, and chronic nephritis, leading to structural and functional kidney injury. Kidney fibrosis is a common outcome of CKD progression, with abnormal fatty acid oxidation (FAO) disrupting renal energy homeostasis and leading to functional impairments. This results in maladaptive repair mechanisms and the secretion of profibrotic factors, and exacerbates renal fibrosis.
