Diverse sex determination mechanisms have been reported in eukaryotes, but little is known about the genetic pathways leading to sex determination in red algae. Sex-specific genes that could be involved in sex determination and sexual differentiation were investigated in the red alga Bostrychia moritziana by analyzing the transcriptomes of various phases including males, females, and tetrasporophytes. Sex dominantly expressed genes which showed >10-fold difference between sexes was isolated using comparative RNA-seq analysis. We found 19 gene homologues, 10 from males, and nine from females, that were found only in one sex in genomic amplification using strains collected from five different localities. Most of the sex-specific genes are involved in important cellular processes including chromosome segregation, nucleo-cytoplasmic protein shuttling, or tRNA modification. Quantitative PCR analysis showed that some sex-specific genes were differently regulated during critical events of sexual reproduction like fertilization and carposporophyte development. We could localize the expression of a male-specific gene in spermatia before and after gamete binding using RNA in situ hybridization. Amino acid sequence identity between male and female homologues of importin alpha gene and PreQ(0) reductase were highly divergent (75% and 74%, respectively), suggesting that these divergent homologues are on non-recombining UV-type chromosomes in their respective sexes. Another set of transcripts were found that were sex dominantly expressed, but not sex-specific. Nineteen out of 39 sex dominantly expressed transcripts were annotated to transposable elements. Our results suggest that sexual differentiation in B. moritziana may be achieved by multi-level regulation of cellular processes, both from genes present only in one sex and differential expression of shared genes.
Donor selection criteria (DSC) are a vital link in the chain of supply of Substances of Human Origin (SoHO) but are also subject to controversy and differences of opinion. Traditionally, DSC have been based on application of the precautionary principle.

From 2017 to 2020, TRANSPOSE (TRANSfusion and transplantation PrOtection and SElection of donors), a European research project, aimed to identify discrepancies between current DSC by proposing a standardized risk assessment method for all SoHO (solid organs excluded) and all levels of evidence.

The current DSC were assessed using a modified risk assessment method based on the Alliance of Blood Operators' Risk-based decision-making framework for blood safety. It was found that with limited or diverging scientific evidence, it was difficult to reach consensus and an international standardized method for decision-making was lacking. Furthermore, participants found it hard to disregard their local guidelines when providing expert opinion, which resulted in substantial influence on the consensus-based decision-making process.

While the field of donation-safety research is expanding rapidly, there is an urgent need to formalize the decision-making process regarding DSC. This includes the need for standardized methods to increase transparency in the international decision-making process and to ensure that this is performed consistently. Our framework provides an easy-to-implement approach for standardizing risk assessments, especially in the context of limited scientific evidence.

Sex selective TGP, via specific lineages or to only male or female descendants, has been underexplored in natural systems, and may be adaptive if it allows past generations to fine-tune the phenotypes of future generations in response to sex-specific life-history strategies. We sought to understand if exposing males to predation risk can influence grandoffspring via sperm in three-spined stickleback Gasterosteus aculeatus. We specifically tested the hypothesis that grandparental effects are transmitted in a sex-specific way down the male lineage, from paternal grandfathers to F2 males. We reared F1 offspring of unexposed and predator-exposed F0 males under 'control' conditions and used them to generate F2s with control grandfathers, a predator-exposed maternal grandfather (i.e. predator-exposed F0 males to F1 daughters to F2s), a predator-elineages. If sex-specific and lineage effects are common, then grandparental effects are likely underestimated in the literature. These results draw attention to the importance of sex-selective inheritance of environmental effects and raise new questions about the proximate and ultimate causes of selective transmission across generations.
The Eating Disorder Inventory provides a theoretically informed multidimensional assessment of eating disorder symptoms and associated psychological factors widely used to examine the development and maintenance of eating disorders. Yet, mixed findings for some factors raise questions about whether their prognostic value varies as a function of duration of follow-up or type of eating pathology studied.

The current study compared prognostic value of perfectionism, maturity fears, and interpersonal distrust as predictors of restrictive versus bulimic symptom patterns at 10-, 20-, and 30-year follow-up in N = 127 individuals diagnosed with eating disorders at baseline. Pifithrin-μ p53 inhibitor Multivariable regression analyses and statistical comparison of effect sizes were used.

Drive for Thinness at 10- and 30-year follow-up was predicted by higher Perfectionism and higher Maturity Fears at baseline. Baseline Maturity Fears also predicted higher Drive for Thinness at 20-year follow-up and higher Bulimia at 10- and 20-year follow-up.
