Alterations in Prefrontal Cortical Somatostatin Neurons in Schizophrenia: Evidence for Weaker Inhibition of Pyramidal Neuron Dendrites.

Biol Psychiatry

January 2025

Translational Neuroscience Program, Department of Psychiatry, School of Medicine, University of Pittsburgh; Department of Neuroscience, Dietrich School of Arts and Sciences, University of Pittsburgh; Center for the Neural Basis of Cognition, Carnegie Mellon University. Electronic address:

Background: Certain cognitive processes require inhibition provided by the somatostatin (SST) class of gamma-aminobutyric acid (GABA) neurons in the dorsolateral prefrontal cortex (DLPFC). This inhibition onto pyramidal neuron dendrites depends on both SST and GABA signaling. Although SST mRNA levels are lower in the DLPFC in schizophrenia, it is not known if SST neurons exhibit alterations in the capacity to synthesize GABA, principally via the 67-kilodalton isoform of glutamic acid decarboxylase (GAD67).

Placenta

January 2025

Mother Infant Research Institute, Tufts Medicine, Boston, MA, USA; Dept Obstetrics & Gynecology, Tufts University, Boston, MA, USA. Electronic address:

Hypothesis: Declines in insulin sensitivity during pregnancy important for fetal growth are associated with impairments in skeletal muscle post-receptor insulin signaling. The primary initiator of these changes is unknown but believed to originate in the placenta. We hypothesize that placental miRNAs are associated with maternal sensitivity changes and impact insulin-sensitive mechanisms in target tissues in vitro.

Lysosomal dysfunction and inflammatory sterol metabolism in pulmonary arterial hypertension.

Science

January 2025

Center for Pulmonary Vascular Biology and Medicine, Pittsburgh, Heart, Lung, and Blood Vascular Medicine Institute, University of Pittsburgh, Pittsburgh, PA, USA.

Vascular inflammation regulates endothelial pathophenotypes, particularly in pulmonary arterial hypertension (PAH). Dysregulated lysosomal activity and cholesterol metabolism activate pathogenic inflammation, but their relevance to PAH is unclear. Nuclear receptor coactivator 7 () deficiency in endothelium produced an oxysterol and bile acid signature through lysosomal dysregulation, promoting endothelial pathophenotypes.

Background: In previous efforts, health-related quality of life (HRQoL) improved for individuals at high risk of type 2 diabetes and cardiovascular disease after participation in community-based lifestyle interventions (LI) with a moderate-to-vigorous physical activity (MVPA) movement goal.

Purpose: It is unknown whether HRQoL improves with LI when the primary movement goal is to reduce sedentary behavior. HRQoL changes were examined among adults with overweight and prediabetes and/or metabolic syndrome randomized to a 12-month Diabetes Prevention Program-based Group Lifestyle Balance (DPP-GLB) community LI work with goals of weight-loss and either increasing MVPA (DPP-GLB) or reducing sedentary time (GLB-SED).

Purpose: Tendon-to-bone repair remains a surgical challenge. Although bone tunnel fixation is a common surgical technique whereby soft tissue is expected to heal against a bone tunnel interface, contemporary methods have yet to recapitulate biomechanical similarity to the native enthesis. In this study, we aimed to understand how inside-out longitudinal tendon inversion affects bone tunnel healing with the hypothesis that inversion removes the gliding epitenon surface to facilitate interface healing.
