Alterations of lung and gut microbiota in sodium butyrate alleviating heat stress-induced lung injury of broilers.

Heat-induced stress has a significant impact on the health of broilers. It induces panting behavior and elevates oxygen consumption, leading to considerable strain on the broiler lungs. However, the precise effects of heat stress on lung injury, along with changes in the lung and gut microbiota, are not yet fully understood.

Quantitative Proteomic and Phosphoproteomic Profiling of Lung Tissues from Pulmonary Arterial Hypertension Rat Model.

Pulmonary arterial hypertension (PAH) is a rare but fatal disease characterized by elevated pulmonary vascular resistance and increased pressure in the distal pulmonary arteries. Systematic analysis of the proteins and pathways involved in the progression of PAH is crucial for understanding the underlying molecular mechanism. In this study, we performed tandem mass tags (TMT)-based relative quantitative proteomic profiling of lung tissues from rats treated with monocrotaline (MCT) for 1, 2, 3 and 4 weeks.

Hydrogen sulfide improves salt tolerance through persulfidation of PMA1 in Arabidopsis.

A new interaction was found between PMA1 and GRF4. HS promotes the interaction through persulfidated Cys446 of PMA1. HS activates PMA1 to maintain K/Na homeostasis through persulfidation under salt stress.

Nitric oxide induces S-nitrosylation of CESA1 and CESA9 and increases cellulose content in Arabidopsis hypocotyls.

Nitric oxide (NO), a small signaling gas molecule, participates in several growth and developmental processes in plants. However, how NO regulates cell wall biosynthesis remains unclear. Here, we demonstrate a positive effect of NO on cellulose content that may be related to S-nitrosylation of cellulose synthase 1 (CESA1) and CESA9.

One-dimensional nitrogen doped porous carbon nano-array arranged by carbon nanotubes for electrochemical sensing ascorbic acid, dopamine and uric acid simultaneously.

In this work, one-dimensional nitrogen doped porous carbon nano-arrays arranged by carbon nanotube (1D CNTs@NPC) were first constructed, using a coating technology at room temperature and followed by high temperature carbonization. It was expected that the resulting glassy carbon electrodes modified by 1D CNTs@NPC (CNTs@NPC/GCE) could express different electrochemical responses to ascorbic acid (AA), dopamine (DA), uric acid (UA), by virtue of the synergistic-improved effect between CNTs and NPC. Under the optimized conditions, there were excellent analytical parameters for CNTs@NPC/GCE to detect AA, DA and UA, i.

Hydrogen Sulfide Positively Regulates Abscisic Acid Signaling through Persulfidation of SnRK2.6 in Guard Cells.

The phytohormone abscisic acid (ABA) plays pivotal roles in triggering stomatal closure and facilitating adaptation of plants to drought stress. Hydrogen sulfide (HS), a small signaling gas molecule, is involved in ABA-dependent stomatal closure. However, how HS regulates ABA signaling remains largely unclear.

Expression, Localization, and Effect of High Salt Intake on Electroneutral Na/HCO Cotransporter NBCn2 in Rat Small Intestine: Implication in Intestinal NaCl Absorption.

The electroneutral Na/HCO cotransporter NBCn2 (SLC4A10) of solute carrier family 4 (SLC4) plays important physiological and pathological roles in the body. Our previous study showed that NBCn2 is expressed on the protein level in the small intestine of rat. Here, by reverse-transcription polymerase chain reaction (PCR), we identified a novel full-length NBCn2 variant, i.

Ethylene-Induced Hydrogen Sulfide Negatively Regulates Ethylene Biosynthesis by Persulfidation of ACO in Tomato Under Osmotic Stress.

A number of recent studies identified hydrogen sulfide (HS) as an important signal in plant development and adaptation to environmental stress. HS has been proven to participate in ethylene-induced stomatal closure, but how the signaling pathways of HS and ethylene interact is still unclear. Here, we reveal how HS controls the feedback-regulation of ethylene biosynthesis in tomato () under osmotic stress.

The Balance of [Formula: see text] Secretion vs. Reabsorption in the Endometrial Epithelium Regulates Uterine Fluid pH.

Uterine fluid contains a high concentration of [Formula: see text] which plays an essential role in sperm capacitation and fertilization. In addition, the [Formula: see text] concentration in uterine fluid changes periodically during the estrous cycle. It is well-known that the endometrial epithelium contains machineries involving the apical SLC26 family anion exchangers for secreting [Formula: see text] into the uterine fluid.
