Intentional Strategic Changes in the National Institute on Aging's RCMAR Program: Broadening its Scope and Reach to Strengthen its Impact.

Since 1997, the Resource Centers for Minority Aging Research (RCMAR) program, supported by the Division of Behavioral and Social Research (BSR) at the National Institute on Aging (NIA), has served as BSR's flagship mentoring program for early-career scientists from diverse backgrounds. The program has undergone significant changes over time, adapting to meet institutional and societal needs. This article highlights the motivations behind programmatic shifts in the fifth funding cycle (2018-2023) and the guiding principles for RCMAR VI (2023-present).

Ambient Stability of Sodium-Doped Copper Oxide Obtained through Thermal Oxidation.

The ambient stability of copper oxide layers produced through thermal oxidation is a critical factor for their application in advanced photovoltaic devices. This study investigates the long-term stability of thermally grown sodium-doped copper oxides fabricated at 300 °C, 500 °C, and 700 °C. The structural, optical, and electronic properties of these oxide layers were examined after a 30-day period to understand how thermal oxidation temperature and sodium doping influence the durability and properties of copper oxide films.

Potential Teratogenicity Effects of Metals on Avian Embryos.

Agricultural areas can provide sources of food and hiding and nesting places for wild birds. Thus, the chemical load of potentially toxic elements (Cd, Cu, Pb) due to industrial and agricultural activities can affect not only the adult birds but also the embryos developing in the egg. The toxic effects of heavy metals applied alone were investigated on chicken embryos in the early and late stages of embryonic development using injection and immersion treatment methods.

Revisiting the dipeptidyl carboxypeptidase inhibitor captopril as a source of pan anti-trypanosomatid agents.

The protozoan parasites Trypanosoma brucei, Trypanosoma cruzi and Leishmania spp. are responsible for continued propagation of neglected tropical diseases such as African sleeping sickness, Chagas disease and leishmaniasis respectively. Following a report that captopril targets Leishmania donovani dipeptidyl carboxypeptidase, a series of simple proline amides and captopril analogues were synthesized and found to exhibit 1-2 μM in vitro inhibition and selectivity against Trypanosoma brucei, Trypanosoma cruzi and Leishmania spp.
