Subjective cognitive decline and objective cognitive performance in older adults: A systematic review of longitudinal and cross-sectional studies.

Older adults with subjective cognitive decline (SCD) have a higher risk of developing future cognitive decline than those without SCD. However, the association between SCD and objective cognitive performance remains unclear. This PRISMA 2020-compliant systematic review aims to provide a qualitative assessment of the longitudinal and cross-sectional relationship between SCD and objective cognitive performance in different cognitive domains, in neuropsychologically healthy, community-dwelling older adults (average age of 55 or older).

Mental rotation, episodic memory, and executive control: Possible effects of biological sex and oral contraceptive use.

Oral contraceptives (OCs) are one of the most common forms of hormonal birth control. A small literature suggests that OC use may affect visuospatial ability, episodic memory, and executive control. However, previous studies have been criticized for small sample sizes and the use of different, single cognitive tests.

Building a national network of student leaders in gerontology: Reflections on the student representative program.

The Canadian Association on Gerontology's Student Connection facilitates a national Student Representative program to promote the field of gerontology at local post-secondary institutions. Student Representatives are expected to host professional development and networking events on their campus to bring together students interested in the field of aging. Student-run groups help foster interest in aging-related careers and research, yet few studies explore how these groups are developed and sustained.

Optical and electrochemical properties of ethynylaniline derivatives of phenothiazine, phenothiazine-5-oxide and phenothiazine-5,5-dioxide.

Three phenothiazine (PTZ) derivatives with varying degrees of sulfur oxidation states were synthesized as strong electron donors. The thioether, sulfoxide and sulfone PTZ-derivatives exhibited irreversible oxidation at 0.19 V, 0.
