Ca2+ signaling is central to plant development and acclimation. While Ca2+-responsive proteins have been investigated intensely in plants, only a few Ca2+-permeable channels have been identified, and our understanding of how intracellular Ca2+ fluxes is facilitated remains limited. Arabidopsis thaliana homologs of the mammalian channel-forming mitochondrial calcium uniporter (MCU) protein showed Ca2+ transport activity in vitro.

Sacubitril/valsartan, simultaneously inhibits neprilysin and angiotensin II receptor, showed an effect in reducing blood pressure (BP). The authors aimed to study whether it can be used as an antihypertensive agent in patients with refractory hypertension who have already been treated. A total of 66 Chinese patients with refractory hypertension were enrolled.

Three new andrastin derivatives, 10-formyl andrastone A (), 10-demethylated andrastone A () and andrastin G (), together with four known andrastin analogues (-) were isolated from an endophytic fungus . Their structures were determined by 1 D, 2 D NMR, and the absolute configurations were further determined by experimental and calculated ECD spectra. Compound exhibited significant antibacterial activity against B with an MIC value of 6.

Acute coronary syndrome caused by the rupture of atherosclerotic plaques is one of the primary causes of cerebrovascular and cardiovascular events. Neovascularization within the plaque is closely associated with its stability. Long non-coding RNA (lncRNA) serves a crucial role in regulating vascular endothelial cells (VECs) proliferation and angiogenesis.

Ca play a key role in cell signaling across organisms. The question of how a simple ion can mediate specific outcomes has spurred research into the role of Ca signatures and their encoding and decoding machinery. Such studies have frequently focused on Ca alone and our understanding of how Ca signaling is integrated with other responses is poor.

Plant WRKY transcription factors (TFs) are active guardians against pathogens' insurgency, key components in developmental processes, contributors in signal transduction pathways, and regulators of diverse biotic and abiotic stress responses. In this research, we isolated, cloned, and functionally characterized a new WRKY TF GmWRKY49 from soybean. GmWRKY49 is a nuclear protein which contains two highly conserved WRKY domains and a CH-type zinc-finger structure.

Background: Preexcitation syndrome is characterized by a dominant delta wave on the baseline electrocardiogram (ECG), resulting from the change in QRS initial vector by the accessory pathway (AP). This study is to explore the effect of ventricular preexcitation on the QRS initial, maximal and terminal vector in an experimental rabbit with preexcitation syndrome induced by programmed electrical stimulation.

Methods: Rabbits (n = 10) were randomized for the experimental model of ventricular preexcitation.

Introduction: Salt stress is one of the most important abiotic stress factors which severely affect agricultural production. Osmotins and OLPs (osmotin like proteins) are kinds of proteins which were produced during plant adapting to the environmental stress.

Objective: These proteins were closely related to osmotic regulation and resistance stress.

Aquaporins (AQPs) are transmembrane protein channels that are members of Major Intrinsic Proteins (MIP) superfamily. AQPs play important roles in plant reproduction, cell elongation, osmoregulation, influence leaf physiology and are responsive to drought and salt tolerance. Small intrinsic proteins (SIPs)belongs to one of the groups of AQPs, which are mainly localized to endoplasmic reticulum(ER).
