Subtle modifications to oxytocin produce ligands that retain potency and improved selectivity across species
In conclusion, [Se-Se]-oxytocin-OH is a novel probe for validating OTR as a therapeutic target in various biological systems and is a promising new lead for therapeutic development. Our medicinal chemistry approach may also be applicable to other peptidergic signaling systems with similar selectivity issues.
This study was designed to test the hypothesis that induced maternal noninfectious fever alters neonatal neural progenitor cell proliferation and enhances microglial activation in the rat dentate gyrus of the hippocampus. METHODS: Systemic vehicle or IL-6 was given 3 times to near-term pregnant rats (n = 7/group) every 90 minutes, and maternal core temperature was recorded. Neonatal brains were processed and analyzed for dentate gyrus cell proliferation (using Ki-67, n = 10/group, and glial fibrillary acidic protein, n = 6/group) and resident microglia activation (using ionized calcium-binding adaptor protein-1 [Iba-1...
ConclusionsIN-associated AEs were identified among patients with UC, with liver dysfunction often being reversible, while surgical resection was required in a high proportion of patients who developed intussusception. Both healthcare workers and patients should adequately recognize the potential for AEs with the use of IN.
ConclusionsChildren born early term are at increased risk of cognitive deficits, poorer school performance, and behavioral problems compared to children born full term.This article is protected by copyright. All rights reserved.

Shelton, Dehui Mi, Paige Vinson, Jennifer Condon, Bibhash C. Paria, Jeff Reese, Quanhu Sheng, Jennifer L. HeringtonAbstractNovel therapeutic regulators of uterine contractility are needed to manage preterm labor, induce labor and control postpartum hemorrhage. Therefore, we previously developed a high-throughput assay for large-scale screening of small molecular compounds to regulate calcium-mobilization in primary mouse uterine myometrial cells. The goal o...
Despite women's preference for induction of labor (IOL) or dilation and evacuation (D&E) for pregnancy termination in the setting of second trimester fetal or pregnancy abnormality, many women are not given a choice between delivery methods. We investigated patient and clinical related factors associated with selecting IOL or D&E.
dsDNA breaks (DSBs) are resected in a 5′→3′ direction, generating single-stranded DNA (ssDNA). This promotes DNA repair by homologous recombination and also assembly of signaling complexes that activate the DNA damage checkpoint effector kinase Chk1. In fission yeast (Schizosaccharomyces pombe), genetic screens have previously uncovered a family of three xeroderma pigmentosum G (XPG)–related nucleases (XRNs), known as Ast1, Exo1, and Rad2. Collectively, these XRNs are recruited to a euchromatic DSB and are required for ssDNA production and end resection across the genome. Here, we studied why there a...

CONCLUSIONS: The most cost-effective policy for detection and management of fetal macrosomia is selective ultrasound scanning coupled with induction of labour for all suspected cases of macrosomia. Universal ultrasound scanning for macrosomia in late-stage pregnancy is not cost-effective. This article is protected by copyright. All rights reserved.

ConclusionsIOL in GDM mothers at term does not reduce CS rate and may be associated with increased CS rate among nulliparous women at 38 weeks. It is also associated with increased risk for adverse composite neonatal outcome or NICU admission when done prior to 390/7 weeks.
