Design of ()-3-(5-Thienyl)carboxamido-2-aminopropanoic Acid Derivatives as Novel NMDA Receptor Glycine Site Agonists: Variation in Molecular Geometry to Improve Potency and Augment GluN2 Subunit-Specific Activity.

NMDA receptor ligands have therapeutic potential in neurological and psychiatric disorders. We designed ()-3-(5-thienyl)carboxamido-2-aminopropanoic acid derivatives with nanomolar agonist potencies at NMDA receptor subtypes (GluN12/A-D). These compounds are superagonists at GluN1/2C compared to glycine and partial to full agonists at GluN1/2A and GluN1/2D but display functional antagonism at GluN1/2B due to low agonist efficacy.

Is Area-Level Social Vulnerability Index Associated With Patient-Level Health-Related Social Needs in Hand Surgery?

Background: Social drivers of health (SDOH) are area-level, nonmedical factors that affect health outcomes. By contrast, health-related social needs (HRSNs) are individual patient reported and are being deployed in some payment models. SDOH are often used to broadly represent health disparities of communities through metrics, such as the Social Vulnerability Index (SVI); however, the association of area-level SVI to individual HRSNs has not been well studied in hand surgery, which has implications for addressing social risks to improve health and in quality measurement.

Human cytomegalovirus gH/gL/gO binding to PDGFRα provides a regulatory signal activating the fusion protein gB that can be blocked by neutralizing antibodies.

Unlabelled: Herpesviruses require membrane fusion for entry and spread, a process facilitated by the fusion glycoprotein B (gB) and the regulatory factor gH/gL. The human cytomegalovirus (HCMV) gH/gL can be modified by the accessory protein gO, or the set of proteins UL128, UL130 and UL131. While the binding of the gH/gL/gO and gH/gL/UL128-131 complexes to cellular receptors including PDFGRα and NRP2 has been well-characterized structurally, the specific role of receptor engagements by the gH/gL/gO and gH/gL/UL128-131 in regulation of fusion has remained unclear.

BCAA interactions: how do they influence broiler performance, intestinal morphometry, lipid profile, and liver health?

An experiment was conducted to assess the effects of the BCAA and their interactions on performance, carcass composition, lipid metabolism, liver health, and intestinal morphometry in broiler chickens. Male chickens ( = 1080) were randomly assigned into floor pens in a 3 × 3 factorial design with 3 dietary ratios of SID Leu:Lys (110, 150, and 190%), and 3 dietary ratios of SID Ile-Val:Lys (68-77, 78-87, and 88-97%). Performance parameters were assessed from 1 to 35 days of age.

Elevated CO in dynamic controlled atmosphere storage: Impact on anaerobic metabolism and overall quality of 'Maxi Gala' apples.

Background: The present study investigated the effects of high CO partial pressures (pCO) in dynamic controlled atmosphere monitored by respiratory quotient (DCA-RQ 1.3) on the anaerobic metabolism compounds, physiological disorders and overall quality of 'Maxi Gala' apples after 9 months of storage (2.0 °C), plus 7 days of shelf life (20 °C).
