Purpose: To investigate whether in diabetic cataract (DC), FoxO1 regulates high glucose (HG)-induced activation of NLRC4/IL-6 inflammatory mediators in human lens epithelial cells (SRA01/04) via the JAK1/STAT1 pathway, leading to cataract formation.
Methods: Expression levels of FoxO1, inflammatory factor IL-6 and inflammatory vesicle NLRC4 were examined in SRA01/04 under high glucose (HG) stress at 25-150 mM. Rat lenses were also cultured using HG medium with or without the addition of the FoxO1 inhibitor AS1842856 and the JAK1 agonist RO8191.

Context: Pachydermoperiostosis (primary hypertrophic osteoarthropathy, PHO) usually due to biallelic loss-of-function variants in HPGD and SLCO2A1, has some features overlapping with acromegaly and often referred to endocrinologists. A detailed endocrine assessment is not available for these patients.
Objective: To assess the genetic and endocrine characteristics of PHO patients referred to endocrine centres with a possible diagnosis of acromegaly.

Periparturient dairy cows experience metabolic adaptations to prepare for increased nutrient requirements of the fetus and the onset of lactation. Adaptations include increased peripheral tissue insulin resistance, which can be evaluated experimentally using intravenous glucose tolerance tests (IVGTT). The objective of this study was to determine if prepartum skeletal muscle reserves and supplementation of branched-chain volatile fatty acids (BCVFA) in the prepartum period affected blood glucose, β-hydroxybutyrate (BHB), and insulin concentrations 2 wk prepartum and 1 wk postpartum utilizing an IVGTT.

In this study, a thermostable β-galactosidase from OSU-PECh-4A has been isolated through diafiltration and size-exclusion chromatography. The enzyme consists of a heterodimer with a molecular mass of 110 kDa, with a small and large subunit of 36 and 74 kDa, respectively. The Michaelis constant (K) and maximum velocity (V) values for lactose and -nitrophenyl-β-d-galactopyranoside (NPG) hydrolysis were, respectively, 29.
