Abstract Frailty is a common comorbidity associated with adverse events in patients heart failure, and early recognition key to improving its management. We hypothesized that the AST ALT ratio (AAR) could be marker of frailty failure. Data from FRAGILE-HF study were analyzed. A total 1327 aged ? 65 years hospitalized failure categorized into three groups based on their AAR at discharge: low (AA...

We tested an immunomarking system that used egg white as marker and enzyme-linked immunosorbent assay as a detection assay to characterize face fly (Musca autumnalis DeGeer) dispersal from cow pats in a pastured beef cattle operation. In microcage assays, adult flies acquired marker after contact with cow pats that were treated with marker and field aged up to 11 d. In arena assays on sprayed f...

The recombination rate in meiosis between the mouse X and Y chromosomes was analyzed. Mice heterozygous at two pseudoautosomal alleles, the steroid sulfatase gene and the Mov-15 provirus marker, were crossed. The provirus in the Mov-15 transgenic mouse strain had been previously shown to be carried in the pseudoautosomal region of the sex chromosomes. Recombination frequencies were shown to be ...

conclusions the current study revealed that a significant difference existed in hgs among the low, medium, and high bmi groups. a positive correlation existed between hgs and weight and height, while sex was the most significant factor affecting hgs. these findings can serve as a reference to assess hgs prediction, whereby the sex effect should be considered. results the results showed that the...

An approach to the optimal utilization of marker and pedigree information in minimizing the rates of inbreeding and genetic drift at the average locus of the genome (not just the marked loci) in a small diploid population is proposed, and its efficiency is investigated by stochastic simulations. The approach is based on estimating the expected pedigree of each chromosome by using marker and ind...

In Drosophila, the sex of XX germ cells is determined by somatic signals. Whether sex-specific genes, however, are activated or repressed by somatic signals is not known. We have used mgm1, a germline-marker which is specifically expressed in male germ cells to analyze sex-specific gene expression of embryonic germ cells. We found that XX and XY germ cells that do not contact gonadal tissue can...

The nature of the cells which proliferate in response to allogeneic histoincompatible lymphocytes in human mixed leukocyte cultures (MLC) was investigated. Direct information on the differentiation of proliferating cells was obtained in an in vitro chimeric system with T- and B-cell sex chromosome markers. Highly purified T and B cells were prepared from the peripheral blood of three pairs of H...

Sex differences in cognition and emotion are particularly active areas of research. Much of this work, however, focuses on mean-level differences between the sexes on cognitive and/or emotional variables in isolation. In this article, we are primarily concerned with how sex affects associations between cognition and emotion, or cognition-emotion interactions. Specifically, the purpose of this p...

Juvenile sex ratios are often assumed to be equal for many species with genetic sex determination, but this has rarely been tested in fish embryos due to their small size and absence of sex-specific markers. We artificially crossed three populations of brown trout and used a recently developed genetic marker for sexing the offspring of both pure and hybrid crosses. Sex ratios (SR = proportion o...

Experimental and field studies of different turtle species suggest that moisture influences embryonic development and sex ratios, wetter substrates tend to produce more males, and drier substrates produce more females. In this study, we used Trachemys scripta elegans to test the effect of moisture on embryonic development and sex ratios. T. s. elegans eggs were incubated under different tempera...
