Overexpression of AspAT alleviates the inhibitory effects of ammonium on root development in Populus tomentosa.

Ammonium toxicity, resulting from prolonged use of ammonium as the sole nitrogen source, can lead to physiological and morphological disorders, ultimately stunting plant growth. Enhancing ammonium assimilation efficiency has been extensively explored as a strategy to mitigate ammonium toxicity. However, the role of AspAT, a key enzyme in nitrogen assimilation, remains underexplored.

The aim of this review was to assess the outcomes of failed PFNAs converted to a UTA or CTA device in elderly individuals with intertrochanteric femoral fractures (IFFs).

Methods: Two hundred fifty-eight elderly individuals (258 hips) with IFFs who underwent a conversion to a UTA or CTA device following failed PFNAs during 2007-2017 were retrospectively identified from the China Southern Medical Centre (CSMC) database.

Favourable clinical outcomes following cemented arthroplasty after metal-on-metal total hip replacement: a retrospective study with a mean follow-up of 10 years.

Background: Given the unexpected high rate of failure following metal-on-metal total hip replacement (MoM-THR), it is expected that more MoM-THR patients will experience revision. The long-term outcomes regarding the primary MoM-THR revised to cemented THR (CTHR) remain controversial. The purpose of this retrospective review was to evaluate the long-term outcomes of patients who underwent conversion from MoM-THR to CTHR.

Data Analysis-Driven Precise Asthmatic Treatment by Targeting Mast Cells.

Background: Although the importance of mast cells in asthma has been studied, mast cellsinduced global changes in lungs are largely unknown. Data-driven identification contributes to discovering significant biomarkers or therapeutic targets, which are the basis of effective clinical medications.

Objective: This study aims to explore the effects of mast cells on gene expression in asthmatic lungs, and to assess the curative effects of inhaled budesonide (BUD).

Hydrogen sulfide primes diabetic wound to close through inhibition of NETosis.

Diabetes-induced neutrophil NETosis impairs wound healing through neutrophil extracellular traps (NETs). Reactive oxygen species (ROS)-triggered activation of mitogen-activated protein kinase (MAPK) ERK1/2 and p38 is involved in NETosis. Hydrogen sulfide (HS), an endogenous signaling molecule, accelerates diabetic wound healing (DWH), and inhibits ROS production, ERK1/2 and p38 activation, while its level is decreased in diabetes.

[Interaction between glycogen synthase kinase-3β and endoplasmic reticulum stress is involved in high glucose-induced injury in human umbilical vein endothelial cells].

Objective: To explore the role of the interaction between glycogen synthase kinase-3β (GSK-3β) and endoplasmic reticulum stress (ERS) in the high glucose (HG)-induced injury in human umbilical vein endothelial cells (HUVECs).

Methods: HUVECs treated with 40 mmol/L glucose for 24 h were examined for expression levels of GSK-3β, GRP78, CHOP and cleaved caspase-3 protein using Western blotting. The cell viability was examined using CCK-8 assay and cell apoptosis was detected with Hoechst 33258 nuclear staining and photofluorography.

Exogenous hydrogen sulfide protects human umbilical vein endothelial cells against high glucose‑induced injury by inhibiting the necroptosis pathway.

Hyperglycemia is a key factor in the development of diabetic complications, including the processes of atherosclerosis. Receptor‑interacting protein 3 (RIP3), a mediator of necroptosis, is implicated in atherosclerosis development. Additionally, hydrogen sulfide (H2S) protects the vascular endothelium against hyperglycemia‑induced injury and attenuates atherosclerosis.

[Angiotensin-(1-7) protects cardiac myocytes against high glucose-induced injury by inhibiting ClC-3 chloride channels].

Objective: To explore whether angiotensin-(1-7) [Ang-(1-7)] protects cardiac myocytes against high glucose (HG)-induced injury by inhibiting ClC-3 chloride channels.

Method: H9c2 cardiac cells were exposed to 35 mmol/L glucose for 24 h to establish a cell injury model. The cells were treated with Ang-(1-7) or the inhibitor of chloride channel (NPPB) in the presence of HG for 24 h to observe the changes in HG-induced cell injury.

A novel damage mechanism: Contribution of the interaction between necroptosis and ROS to high glucose-induced injury and inflammation in H9c2 cardiac cells.

Recently, a novel mechanism known as 'programmed necrosis' or necroptosis has been shown to be another important mechanism of cell death in the heart. In this study, we investigated the role of necroptosis in high glucose (HG)-induced injury and inflammation, as well as the underlying mechanisms. In particular, we focused on the interaction between necroptosis and reactive oxygen species (ROS) in H9c2 cardiac cells.

The Opening of ATP-Sensitive K+ Channels Protects H9c2 Cardiac Cells Against the High Glucose-Induced Injury and Inflammation by Inhibiting the ROS-TLR4-Necroptosis Pathway.

Background/aims: Hyperglycemia activates multiple signaling molecules, including reactive oxygen species (ROS), toll-like receptor 4 (TLR4), receptor-interacting protein 3 (RIP3, a kinase promoting necroptosis), which mediate hyperglycemia-induced cardiac injury. This study explored whether inhibition of ROS-TLR4-necroptosis pathway contributed to the protection of ATP-sensitive K+ (KATP) channel opening against high glucose-induced cardiac injury and inflammation.

Methods: H9c2 cardiac cells were treated with 35 mM glucose (HG) to establish a model of HG-induced insults.
