Analysis of XX SRY-Negative Sex Reversal Dogs

open access: yesAnimals, 2020
Impaired fertility associated with disorders of sex development (DSDs) due to genetic causes in dogs are more and more frequently reported. Affected dogs are usually of specific breeds thus representing a cause of economic losses for breeders. The aim of

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

GROWTH PERFORMANCE, FEED UTILIZATION AND CARCASS COMPOSITION COMPARISONS OF MONOSEX TILAPIA (Oreochromis niloticus) PRODUCED BY VARIOUS TECHNIQUES. [PDF]

open access: yesJournal of Animal and Poultry Production, 2004
The present study was conducted to compare growth, feed utilization and carcass composition (Oreochromis niloficus) monosex, produced through separation of sexes (male or female) and hormonal sex reversal techniques with (0,20,40,60 and 80 %) female ...

Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

Sex reversal, growth, and survival in the guppy Poecilia reticulata (Cyprinodontiformes: Poeciliidae) under laboratory conditions

open access: yesCuadernos de investigación UNED, 2013
Just like it is important to obtain robust and heavy fish in short periods in aquaculture, in aquariology it is important to efficiently obtain colorful fish, which are usually males, and this makes sex reversal important.

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

open access: yesFEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Transcriptome analysis of four types of gonadal tissues in largemouth bass (Micropterus salmoides) to reveal its sex-related genes

open access: yesFrontiers in Genetics
The sex determination system of largemouth bass (Micropterus salmoides, LMB) is XX/XY; however, the underlying molecular mechanisms involved in early sex differentiation, gonadal development, and exogenous hormone-induced sex reversal remain unknown.

Dynamics of a sex-linked deleterious mutation in populations subject to sex reversal.

open access: yesPLoS ONE, 2011
The heterogametic sex chromosomes (i.e. mammalian Y and avian W) do not usually recombine with the homogametic sex chromosomes which is known to lead into rapid degeneration of Y and W due to accumulation of deleterious mutations. On the other hand, some

Sex-dependent effects of chronic intermittent voluntary alcohol consumption on attentional, not motivational, measures during probabilistic learning and reversal.

open access: yesPLoS ONE, 2020
BackgroundForced alcohol (ethanol, EtOH) exposure has been shown to cause significant impairments on reversal learning, a widely-used assay of cognitive flexibility, specifically on fully-predictive, deterministic versions of this task. However, previous

Sex chromosome and sex locus characterization in goldfish, Carassius auratus (Linnaeus, 1758)

open access: yesBMC Genomics, 2020
Background Goldfish is an important model for various areas of research, including neural development and behavior and a species of significant importance in aquaculture, especially as an ornamental species.
