, a Pepper ( L.) Dehydrin Gene Enhances the Tolerance against Salt and Drought Stresses by Reducing ROS Accumulation.

Dehydrins (DHNs) play an important role in abiotic stress tolerance in a large number of plants, but very little is known about the function of DHNs in pepper plants. Here, we isolated a YSK-type DHN gene "" from pepper. To authenticate the function of in salt and drought stresses, it was overexpressed in Arabidopsis and silenced in pepper through virus-induced gene silencing (VIGS).

Regulation of Sirtuin 3-Mediated Deacetylation of Cyclophilin D Attenuated Cognitive Dysfunction Induced by Sepsis-Associated Encephalopathy in Mice.

The present study aimed to investigate cognitive dysfunction in the hippocampus induced by sepsis-associated encephalopathy (SAE) via acetylation of cyclophilin D (CypD) and opening of mitochondrial permeability transition pore. It also explored whether activating sirtuin 3 (SIRT3) can mediate deacetylation of CypD and prevent the development of SAE. Male mice were randomly assigned to six groups: sham group, cecal ligation puncture group, CypD siRNA transfection (CypD-si) group, CypD control siRNA transfection (CypD-c) group, SIRT3 overexpression vector pcDNA3.

[Effects of dexmedetomidine on microcirculatory perfusion in rabbits with renal ischemia/reperfusion injury: quantitative evaluation with contrast-enhanced ultrasound].

Objective: To investigate the effects of dexmedetomidine on renal microcirculatory perfusion in rabbits with renal ischemia/reperfusion (I/R) injury rabbit by quantitative analysis of contrast-enhanced ultrasound (CEUS).

Methods: Twenty- four New Zealand rabbits were randomly divided into 3 groups (8 in each), including a control group, renal I/R injury group and dexmedetomidine group. In the latter two groups, the right kidney of the rabbits was resected and I/R injury was induced in the left kidney.
