Targeted delivery of a selenium-sulfa compound via cationic starch microparticles: Modulation of oxidative stress and pain pathways in fibromyalgia-like symptoms in mice.

Cationic starch microparticles (CStMPs) loaded with 4-amino-3 -(phenylselenyl)benzenesulfonamide (4-APSB) were prepared and investigated in a model of fibromyalgia (FM) induced by intermittent cold stress (ICS) in male and female Swiss mice. The CStMPs/4-APSB were characterized by Fourier transform infrared (FTIR) spectroscopy, scanning electron microscopy (SEM), energy-dispersive X-ray (EDX) spectroscopy, zeta potential, and particle size measurements, providing information about their chemical composition, surface charge, morphology/microstructure, and size (1.50 ± 0.

Ohmic pasteurization of probiotic chocolate dairy desserts and its quality attributes.

The study evaluated the effects of conventional pasteurization and ohmic heating (OH) at different electric fields (12, 16, 20, or 24 V/cm) on probiotic chocolate dairy desserts' physicochemical, microbiological, sensory properties and volatile profiles. Both treatments were analyzed for parameters such as pH, syneresis, cream stability index, rheology, bioactive compounds (total phenolics and antioxidant capacity), and probiotic viability (Lactobacillus acidophilus LA-05) over a 28-day storage period. Ohmic heating at higher electric fields (20 and 24 V/cm) showed comparable results to pasteurization for most parameters, with non-significant differences or even higher values for some.

A chloro substituted organoselenium mitigates stress-associated memory impairment and hippocampal glutamatergic function in a repeated Forced Swim Stress Model.

Stress is triggered by a threatening event that alters the regulation of emotion, behavior, and cognition. The effects of stress on memory in animal models are well-documented. Firstly, this study aimed to determine whether the repeated forced swim stress (FSS) protocol induces memory impairment comparable to single prolonged stress (SPS) in the Y-maze test.

The 7-chloro-4-(phenylselanyl) quinoline (4-PSQ) shows promise for its antinociceptive and anti-inflammatory properties. Here, we explored the structure-activity relationship of 4-PSQ and its analogues: 7-chloro-4-[(4-fluorophenyl) selanyl]quinoline (a), 7-chloro-4-{[3-trifluoromethyl)phenyl] selanyl} quinoline (b), 4-((3,5-Bis(trifluoromethyl)phenyl) selanyl-7-chloroquinoline (c), 7-chloro-4-[(2,4,6-trimethyl)selanyl]quinolinic acid (d) and 7-chloroquinoline-4-selenium acid (e) in models of acute inflammation and chemical, thermal and mechanical nociception in mice, alongside in silico analysis. Compounds a (-F), b (-CF), c (-Bis-CF), d (-CH), e (-OOH), and 4-PSQ exhibited antinociceptive effects in chemical and thermal nociception models, except d (-CH) and e (-OOH) in the hot plate test.

Transcription factor HNF4α2 promotes osteogenesis and prevents bone abnormalities in mice with renal osteodystrophy.

Renal osteodystrophy (ROD) is a disorder of bone metabolism that affects virtually all patients with chronic kidney disease (CKD) and is associated with adverse clinical outcomes including fractures, cardiovascular events, and death. In this study, we showed that hepatocyte nuclear factor 4α (HNF4α), a transcription factor mostly expressed in the liver, is also expressed in bone, and that osseous HNF4α expression was dramatically reduced in patients and mice with ROD. Osteoblast-specific deletion of Hnf4α resulted in impaired osteogenesis in cells and mice.
