Dissolved Nitrogen Cycling in the Eastern Canadian Arctic Archipelago and Baffin Bay From Stable Isotopic Data.

Climate change is expected to alter the input of nitrogen (N) sources in the Eastern Canadian Arctic Archipelago and Baffin Bay due to increased discharge from glacial meltwater and permafrost thaw. Since dissolved inorganic N is generally depleted in surface waters, dissolved organic N (DON) could represent a significant N source fueling phytoplankton activity in Arctic ecosystems. Yet, few DON data for this region exist.

Uncovering Important Diagnostic Features for Alzheimer's, Parkinson's and Other Dementias Using Interpretable Association Mining Methods.

Alzheimer's Disease and Related Dementias (ADRD) afflict almost 7 million people in the USA alone. The majority of research in ADRD is conducted using post-mortem samples of brain tissue or carefully recruited clinical trial patients. While these resources are excellent, they suffer from lack of sex/gender, and racial/ethnic inclusiveness.

Individualized Coordination and Empowerment for Care Partners of Persons with Dementia (ICECaP): Feasibility and acceptability.

Background: Informal care partners (CPs) of persons with dementia (PWDs), who are at risk of negative health outcomes, benefit from psychosocial interventions. Individualized Coordination and Empowerment for CPs of PWDs (ICECaP) is a year-long, multi-component intervention comprised of in-person and telehealth psychoeducation and emotional support from dementia care coordinators (DCCs). ICECaP feasibility and acceptability were examined during a pilot randomized controlled trial.

Covalent Inhibitors of KEAP1 with Exquisite Selectivity.

The NRF2-KEAP1 interaction is central for cytoprotection against stresses, giving it high clinical significance. Covalent modification of KEAP1 is an efficient approach, but the covalent inhibitors used in the clinic carry undesired side effects originating in their moderate selectivity. Starting with a phenotypic screen, we identified a new covalent inhibitor chemotype that was optimized to deliver a series of potent and highly selective KEAP1 binders.
