Axial Chirality Control Through Palladium‐Catalyzed Alkenylation Reactions for the Atroposelective Synthesis of 4‐Arylquinolin‐2‐ones

European Journal of Organic Chemistry, EarlyView.
Palladium(II)‐catalyzed intramolecular C─H alkenylation of cinnamides allows the atroposelective synthesis of axially chiral 4‐arylquinolones, with the chirality being installed by ring formation. DFT studies have shown that the reaction proceeds by prior activation of the alkene and the enantioselectivity is determined during the β‐hydride elimination

Prenatal betamethasone–postnatal N‐methyl‐D‐aspartic acid model of spasms: Update on mechanisms and treatments

Epilepsia Open, EarlyView.
Abstract Infantile epilepsy spasms syndrome (IESS), formerly known as infantile spasms or West Syndrome, is a severe epilepsy syndrome affecting about 3 in 10,000 newborns in the United States. Characterized by clusters of epileptic spasms, interictal hypsarrhythmia, and developmental delays, IESS has diverse causes, including structural‐metabolic ...

The effects of acute exercise on plasma oxytocin [PDF]

, 2018
Oxytocin is a nine-amino acid peptide hormone and/or neuropeptide that has proposed mechanisms related to diminishing the effects of physical, psychological, and psychosocial stress. Exercise is often used in clinical trials to quantify stress because it

Age, embryo donor status, and insemination with chilled semen all predispose to persistent breeding‐induced endometritis in warmblood mares

Equine Veterinary Journal, EarlyView.
Abstract Background Persistent breeding‐induced endometritis (PBIE) is a common reason for mares failing to establish pregnancy. Objective To examine the hypothesis that advancing mare age and embryo donor status predispose to PBIE and compromise fertility.

Oxytocin alleviates liver fibrosis via hepatic macrophages

JHEP Reports
Background & Aims: Previous studies demonstrated oxytocin treatment effectiveness in reducing mortality and reversing liver fibrosis in mice. However, the underlying mechanism remains obscure, given the absence of oxytocin receptor expression in ...

Does induction or augmentation of labor increase the risk of postpartum hemorrhage in pregnant women with anemia? A multicenter prospective cohort study in India

International Journal of Gynecology &Obstetrics, Volume 169, Issue 1, Page 299-309, April 2025.
Abstract Objective To investigate whether induction/augmentation of labor in pregnant women with anemia increases the risk of postpartum hemorrhage (PPH) and whether this risk varied by indications for labor induction/augmentation and by anemia severity in pregnancy.

Network meta‐analysis of tocolytics in preterm labor: Establishing an evidence‐based treatment hierarchy

International Journal of Gynecology &Obstetrics, EarlyView.
Abstract Background The choice of tocolytic drugs is one of the most debated aspects of preterm birth management. Objective This network meta‐analysis aimed to establish an evidence‐based hierarchy for tocolytics used in preterm labor by evaluating their efficacy in delaying delivery, safety, and neonatal outcomes.

Oxytocin at physiological concentrations evokes adrenocorticotropin (ACTH) release from corticotrophs by increasing intracellular free calcium mobilized mainly from intracellular stores. Oxytocin displays synergistic or additive effects on ACTH-releasing factor or arginine vasopressin-induced ACTH secretion, respectively [PDF]

, 1992
The potency of oxytocin (OT) in evoking ACTH secretion by isolated, superfused rat adenohypophyseal corticotrophs and its enhancement by CRF and arginine vasopressin (AVP) were analyzed.

Chronic oxytocin administration stimulates the oxytocinergic system in children with autism

Nature Communications
Clinical efficacy of intranasal administration of oxytocin is increasingly explored in autism spectrum disorder, but to date, the biological effects of chronic administration regimes on endogenous oxytocinergic function are largely unknown.
