4-Amino-3,5-di-chloro-pyridine.

The title compound, CHClN, crystallizes with one mol-ecule in the asymmetric unit. In the crystal, the mol-ecular entities are assembled through strong N-H⋯N hydrogen bonding, forming supra-molecular chains extending along the axis direction. These chains are inter-connected by offset π-π stacking inter-actions and consolidated by halogen-π inter-actions.

Cooperative Atomically Dispersed Fe-N and Sn-N Moieties for Durable and More Active Oxygen Electroreduction in Fuel Cells.

One grand challenge for deploying porous carbons with embedded metal-nitrogen-carbon (M-N-C) moieties as platinum group metal (PGM)-free electrocatalysts in proton-exchange membrane fuel cells is their fast degradation and inferior activity. Here, we report the modulation of the local environment at Fe-N sites via the application of atomic Sn-N sites for simultaneously improved durability and activity. We discovered that Sn-N sites not only promote the formation of the more stable D2 FeNC sites but also invoke a unique D3 SnN-FeN site that is characterized by having atomically dispersed bridged Sn-N and Fe-N.

Satisfaction With Virtual Consultation Services and Associated Factors Among Health Care Providers in Government Health Clinics in Selangor, Malaysia.

Background:  In Malaysia, virtual consultation services (VCSs) have been implemented by the Ministry of Health (MOH) since 2019 to complement current healthcare service delivery in government health clinics. Although the services have been proven to benefit patients, little is known about the satisfaction of healthcare providers (HCPs) who run the services. This study utilizes the extended Technology Acceptance Model to evaluate the satisfaction of HCPs with VCS and identify associated factors to further improve these services.

Dietary menhaden fish oil supplementation suppresses lipopolysaccharide-induced neuroinflammation and cognitive impairment in diabetic rats.

Context: Menhaden fish oil (FO) is widely recognized for inhibiting neuroinflammatory responses and preserving brain function. Nevertheless, the mechanisms of FO influencing brain cognitive function in diabetic states remain unclear.

Objective: This study examines the potential role of FO in suppressing LPS-induced neuroinflammation and cognitive impairment in diabetic animals (DA).
