We report here on ethical considerations addressing the idiosyncratic needs of two Orthodox Jewish couples requesting sex selection through PGD. The patients' considerations stem from generally healthy concerns, are not based on any gender biases and have little chance of having any major societal impact, given the idiosyncratic nature of the situation. Halakhah, the legal and ethical system of rabbinic Orthodox Judaism, generally opposes sex selection through PGD for nonmedical reasons, but would approve the procedure in these cases. Meeting these needs within the context of the doctor-patient relationship necessitates reconsidering to some extent the ASRM Ethics Committee guidelines.

Skin cancers continue to present unresolved challenges, particularly regarding the association with sex hormones, which remains a topic of controversy. A systematic review is currently warranted to address these issues. To analyze if sex hormones result in a higher incidence of skin cancers (cutaneous melanoma, basal cell carcinoma, squamous cell carcinoma).

Background: Trait variation is shaped by functional roles of traits and the strength and direction of selection acting on the traits. We hypothesized that in butterflies, sexually selected colouration is more variable owing to condition-dependent nature and directional selection on sexual ornaments, whereas naturally selected colouration may be less variable because of stabilising selection. We measured reflectance spectra, and extracted colour parameters, to compare the amount of variation in sexually versus naturally selected colour patches across wing surfaces and sexes of 20 butterfly species across 4 families (Nymphalidae, Papilionidae, Pieridae, Lycaenidae).

Species that coexist in hybrid zones sexually isolate through reproductive character displacement, a mechanism that favours divergence between species. In Drosophila, behavioural and physiological traits discourage heterospecific mating between species. Recently, social network analysis revealed flies produce strain-specific and species-specific social structures.

Objectives: Proliferative lupus nephritis (LN) is not uncommon in individuals with proteinuria < 0.5 g/24h, highlighting the importance of predicting proliferative nephritis for effective clinical management. We aimed to develop a predictive model for proliferative nephritis in this population.

Chronological age is a major risk factor for numerous diseases. However, chronological age does not capture the complex biological aging process. the difference between the chronological age and biologically driven aging could be more informative in reflecting health status.
