Investigating adaptive sport participation for adults aged 50 years or older with spinal cord injury or disease: A descriptive cross-sectional survey.

Context: Spinal cord injury or disease (SCI/D) can lead to health challenges that are exacerbated with aging. Adaptive sport is understood to provide health benefits for the SCI/D population. Prior literature investigating adaptive sport in this population pertains to adults with SCI/D who are <50 years of age.

The phosphodiesterase 3 inhibitor ORG 9935 inhibits oocyte maturation during gonadotropin-stimulated ovarian cycles in rhesus macaques.

To determine whether phosphodiesterase (PDE) 3 inhibitors prevent the resumption of meiosis by primate oocytes in vivo, rhesus macaques were stimulated to develop multiple preovulatory follicles by administering human recombinant gonadotropins, and follicles were aspirated 34 h after an ovulatory stimulus (human chorionic gonadotropin [hCG]). Monkeys received no further treatment (controls) or the PDE3 inhibitor ORG 9935 (a) exclusively in the periovulatory interval beginning 6-12 h prior to receiving hCG at 200 mg/kg every 12 h orally (PER200) or a 200 mg/kg oral loading dose followed by 50 mg/kg sc every 6 h (PER50) or (b) throughout the ovarian stimulation protocol with daily increases until a dose of 200 mg/kg bid was administered onward from the eighth day of ovarian stimulation (EXT200). The primary outcome was the number of oocytes that had resumed meiosis (germinal vesicle breakdown [GVBD]) at collection.

Identification and characterization of an ovary-selective isoform of epoxide hydrolase.

A novel ovary-selective gene was identified by suppression subtractive hybridization (SSH) that is expressed only during the mouse periovulatory phase of a stimulated estrous cycle. Analysis of the protein encoded by the full-length cDNA revealed that the majority of it, with the exception of the first 44 amino acids, matched soluble epoxide hydrolase (Ephx2, referred to as Ephx2A). By comparing the cDNA sequence of this newly identified variant of soluble epoxide hydrolase (referred to as Ephx2B) with the mouse genome database, an exon was identified that corresponds to its unique 5' cDNA sequence.
