Black skin, compared with white skin, is generally assumed to be more resistant to the consequences of sun exposure due to its epidermal melanin content. However, recent scientific evidence shows that black skin is not completely impervious to sunlight. Both clinical and -experimental data have reported sun-induced effects on black skin. Black skin can warm, burn and peel when -exposed to the sun. Exposure to the sun can also cause hyperpigmentation and photoageing manifestations. The current misconceptions expressed by most black individuals about their resistance to sun-induced effects prevent their engagement in sun safe behaviours. Therefore, the demystification of the harmful effects of the sun needs to be supported by more research studies showing the effectiveness of sun protection strategies for the black population.

In this study, residue depletion and withdrawal time estimation of tilmicosin were examined in Taihe black-bone silky fowls (TBSFs) after oral administration for three consecutive days at a dose of 75 mg/L in water. The tilmicosin concentrations in liver, kidney, muscle, and skin/fat of TBSFs collected from different time points (0.16, 1, 3, 5, 7, 9, 12, 20, 30, 40 days after last administration) were determined by UPLC-MS/MS.

With the rapid advance of technology, human interactions with virtual avatars in simulated social environments are becoming increasingly common. The aim of the current study was to examine users' perception of social traits and emotions of "neutral," expressionless avatars using an open-source collection. These avatars represented different ethnicities, genders, and occupations via visual features including skin tone, facial structure, and apparel.

Young Black women in the southern US face a high HIV burden. While daily oral HIV pre-exposure prophylaxis (PrEP) can effectively prevent HIV, its use is low among Black women. The acceptability of and perceived intention to use emerging PrEP products among young Black women in the southern US are not well understood.
