Phasic dopamine release in two different rat models of attention-deficit/hyperactivity disorder: Spontaneously hypertensive rats (SHR) versus Lphn3 knockout rats.

We examined DA activity in the medial prefrontal cortex (mPFC) and nucleus accumbens core (NAcc) in two Different Rat Models of Attention-Deficit/Hyperactivity Disorder: Spontaneously Hypertensive Rats (SHR) Versus Lphn3 Knockout Rats. We examined baseline stimulation-evoked phasic DA release, half-life, and DA autoreceptor (DAR) functioning in the mPFC and NAcc, as well as the response to nomifensine (10 mg/kg, IP), a DA transporter (DAT) blocker, on these measures in the NAcc. Both rat models were hypodopaminergic, with notable regional and mechanistic differences.

Modifies Chronic Airway Infection Risk in Cystic Fibrosis.

Rationale: Chronic () airway infection is common and a key contributor to diminished lung function and early mortality in persons with cystic fibrosis (PwCF). Risk factors for chronic among PwCF include cystic fibrosis transmembrane conductance regulator genotype, genetic modifiers, and environmental factors. Intensive antibiotic therapy and highly effective modulators do not eradicate in most adolescents and adults with cystic fibrosis.

The First Nations Community Experiences With the SOAR Research Program: Improving Type 2 Diabetes Prevention and Management.

Objectives: Indigenous peoples in Canada are considered the highest risk populations for type 2 diabetes mellitus (T2DM). Quality improvement (QI) strategies may be considered effective interventions for improving T2DM health outcomes. The purpose of this study was to understand experiences associated with implementation of the SOAR QI program to improve prevention and management of T2DM.

A bioinspired water oxidation catalyst that is ∼1/10 as active as the photosystem II oxygen evolving center at pH 7: a study of activity and stability factors.

The activity and stability of a heterogeneous water oxidation catalyst inspired by the Photosystem II - Oxygen Evolving Center (PSII-OEC) is reported. Ca-doped birnessite MnO supported on a liquid crystalline reduced graphene oxide (LCrGO) substrate exhibited unprecedented performance for an abiological catalyst at pH 7, including an exceedingly low onset overpotential of 0.52 V (.

Associations between SARS-CoV-2 Infection or COVID-19 Vaccination and Human Milk Composition: A Multi-Omics Approach.

Background: The risk of contracting severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) via human milk-feeding is virtually nonexistent. Adverse effects of coronavirus disease 2019 (COVID-19) vaccination for lactating individuals are not different from the general population, and no evidence has been found that their infants exhibit adverse effects. Yet, there remains substantial hesitation among this population globally regarding the safety of these vaccines.
