Stability of a Multiresponsive Sulfonium Vinyl Sulfide Linker toward Nucleophilic/Radical Thiols, Reactive Nitrogen Species, and in Cells under Pro-inflammatory Stimulation.

Chemical linkages that respond to biological stimuli are important for many pharmaceutical and biotechnological applications, making it relevant to explore new variants with different responsivity profiles. This work explores the responsiveness of a TAT peptide-based sulfonium vinyl sulfide probe that responds to nucleophilic thiols, radical thiol species (RTS), and reactive nitrogen species (RNS). Under model conditions, response to nucleophilic thiols was very slow (hours/days), though fast with down to molar equivalents of either RTS or RNS (minutes).

Vagus Nerve Stimulation Modulates Inflammation in Treatment-Resistant Depression Patients: A Pilot Study.

Vagal neurostimulation (VNS) is used for the treatment of epilepsy and major medical-refractory depression. VNS has neuropsychiatric functions and systemic anti-inflammatory activity. The objective of this study is to measure the clinical efficacy and impact of VNS modulation in depressive patients.

NRF2 Deficiency Attenuates Diabetic Kidney Disease in Db/Db Mice via Down-Regulation of Angiotensinogen, SGLT2, CD36, and FABP4 Expression and Lipid Accumulation in Renal Proximal Tubular Cells.

The role(s) of nuclear factor erythroid 2-related factor 2 (NRF2) in diabetic kidney disease (DKD) is/are controversial. We hypothesized that Nrf2 deficiency in type 2 diabetes (T2D) db/db mice (db/db knockout (KO)) attenuates DKD progression through the down-regulation of angiotensinogen (AGT), sodium-glucose cotransporter-2 (SGLT2), scavenger receptor CD36, and fatty -acid-binding protein 4 (FABP4), and lipid accumulation in renal proximal tubular cells (RPTCs). Db/db KO mice were studied at 16 weeks of age.

Suspected medullary washout leading to severe polyuria following delayed cerebral ischemia: a case report.

Background: Delayed cerebral ischemia is a clinical entity commonly encountered in patients presenting with acute neurological injury and is often complicated by dysnatremias, such as the cerebral salt wasting syndrome. In this case report, we described an exceptional case of polyuria attributed to an initial cerebral salt wasting phenomenon and iatrogenic-induced medullary washout.

Case Presentation: A 53-year-old woman was admitted to our hospital for the management of a Modified Fisher scale grade 4 subarachnoid hemorrhage due to a ruptured posterior communicating aneurysm.
