Differential isoform expression and alternative splicing in sex determination in mice

BMC Genomics, 2019
Background Alternative splicing (AS) may play an important role in gonadal sex determination (GSD) in mammals. The present study was designed to identify differentially expressed isoforms and AS modifications accompanying GSD in mice.

Molecular Regulation of Post‐Hatching Embryo Development: Implications for Early Pregnancy Losses in Livestock Species

Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.
ABSTRACT Pregnancy loss (PL) remains a major limitation to reproductive efficiency in livestock, with a substantial proportion originating during early embryo development, particularly between blastocyst hatching and implantation. This developmental window encompasses complex processes of lineage differentiation and morphogenesis. Accumulating evidence

Population dynamics of potentially harmful haplotypes: a pedigree analysis

BMC Genomics
Background The identification of low-frequency haplotypes, never observed in homozygous state in a population, is considered informative on the presence of potentially harmful alleles (candidate alleles), putatively involved in inbreeding depression ...

Functional and Fertility Outcomes of Two Milk‐Based Extenders for Short‐Term Storage of Ram Semen at 15°C

Reproduction in Domestic Animals, Volume 61, Issue S3, October 2026.
ABSTRACT The efficiency of AI in sheep depends partly on maintaining sperm function during storage. This study compared INRA 96 and a skim milk‐based formulation for storing ram semen at 15°C for 6 h, evaluating sperm quality and IVF and field fertility outcomes. INRA 96 showed higher VCL, ALH, and sperm viability after 6 h of storage.

Social isolation does not inhibit sexual behaviour and testosterone secretion in sexually inexperienced photo-stimulated bucks in contact with seasonally anoestrous goats

Italian Journal of Animal Science, 2020
The aims of this study were to determine: (i) whether sexually inexperienced photo-stimulated males housed individually in pens display less intense sexual behaviour than sexually inexperienced photo-stimulated males housed in a group, and (ii) whether ...

Framing Displacement, Forcing Perspective: Black Visual Geographies and the Crisis of Homelessness in Oakland

Antipode, Volume 58, Issue 5, September 2026.
ABSTRACT While Black and visual geographies have examined the image's racial and spatial power, more work is needed to analyze how racial frames of view become spatially embedded. This paper advances such a practice by analyzing news images of homelessness in Oakland.

Ephemeral Earthmoving Labour Versus the Great Acceleration: (Re)producing the Flux Urban Political Ecologies of Bolivian Amazonia

Antipode, Volume 58, Issue 5, September 2026.
ABSTRACT The article investigates how Indigenous labour interacts with powerful sediment movements and flooding cycles in 23 riverine communities in Bolivian Amazonia. These interactions, we argue, transcend the binary between human labour and biophysical processes in shaping flux urban political ecologies, landscapes and human settlements that ...
