Fatty Acid Prof iles of Ram's Sperm after Removing Some Fatty Acid Sources from the Diets and Persistency of Fatty Acids in Sperm [PDF]

International Journal of Fertility and Sterility, 2012
Background Mammalian spermatozoa are characterized by a high proportion of polyunsaturated fatty acids (PUFAs), but reliable data concerning dietary effects on fatty acid (FA) profile in ram's sperm and the persistency of FA in the ration to the FA in

Effects of tempol on renal medullary tissue hypoxia in an ovine model of Gram‐negative septic acute kidney injury

Experimental Physiology, EarlyView.
Abstract Renal arterial infusion of tempol (RAT) at the onset of Gram‐negative sepsis can prevent sepsis‐induced medullary tissue hypoxia and acute kidney injury (AKI). However, it is not known whether treatment with tempol at a clinically relevant time point of sepsis is similarly effective. Thus, we examined whether tempol can reverse renal medullary

A new approach to an old disease: Ageing, arrhythmogenic substrate and the role of risk‐factor modification in atrial fibrillation

Experimental Physiology, EarlyView.
Abstract Atrial fibrillation (AF) prevalence rises sharply with age due to two independent mechanisms. Ageing produces irreversible arrhythmogenic substrate changes through progressive fibrosis, cellular senescence and mitochondrial dysfunction, while modifiable risk factors such as obesity, hypertension, sleep apnoea, diabetes and alcohol use promote ...

Placental mitochondrial metabolic adaptation maintains cellular energy balance in pregnancy complicated by gestational hypoxia

The Journal of Physiology, EarlyView.
Abstract figure legend Placental mitochondrial adaptation to gestational hypoxia. Hypoxic pregnancy in sheep increases placental insulin like growth factor 2 (IGF2) signalling (1), which is associated with a shift in capacity away from β‐oxidation (2) and complex I‐mediated respiration (3), while maintaining total oxidative phosphorylation capacity (4).

A Porcine Model of Intervertebral Disc Injury Recapitulates Human Discogenic Pain Via Notochordal Cell Loss and Pain‐Inducing Nucleus Pulposus Cell Emergence

JOR SPINE, Volume 9, Issue 3, September 2026.
A porcine model of disc injury recapitulates key clinical, histological, and molecular features of human discogenic low back pain. Multi‐omics analyses identify a shift from notochordal cells to pain‐associated nucleus pulposus cells as a potential driver of disease progression. ABSTRACT Background Lower back pain (LBP) is one of the most common causes

Large Language Models in Preclinical Spine Research: A Scoping Review and Expert Perspective on Evidence‐Aware Experimental Workflows

JOR SPINE, Volume 9, Issue 3, September 2026.
ABSTRACT Background Preclinical spine research is limited by heterogeneous experimental reporting, fragmented documentation, and barriers to reproducibility and translational alignment. Large language models (LLMs) and related artificial intelligence (AI) technologies may support semantic interpretation, structured data extraction, and reasoning over ...

Spatial Investigation of Facet Joint Cartilage Properties Reveals Specific Structure–Function Relationships

JOR SPINE, Volume 9, Issue 3, September 2026.
The inferior facet of the L2 vertebra and the superior facet of the L3 vertebra were harvested from ovine lumbar spines. The spatial biomechanical properties of the facet cartilage surfaces were determined by indentation mapping. Cartilage structure was spatially analyzed on a macroscopic and microscopic level.

Characterization of Phylogroups, Virulence Factors and Antimicrobial Resistance in Canine Pyometra‐associated Escherichia coli

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.
This study characterized 56 Escherichia coli isolates obtained from canine pyometra, which predominantly belonged to phylogroup B2 and harboured multiple virulence genes, with high multidrug resistance rates indicating potential clinical and zoonotic risks. ABSTRACT The presence of multidrug‐resistant extraintestinal pathogenic Escherichia coli (ExPEC)

Unraveling the Evolutionary History of Snow Sheep (Ovis nivicola): Genome‐Wide Single Nucleotide Polymorphism Analysis Reveals Genetic Diversity and Clarifies Taxonomy

Ecology and Evolution, Volume 16, Issue 8, August 2026.
This study chronicles all described subspecies of snow sheep (Ovis nivicola) since 1829, reviewing taxonomic assessments by key systematists. Using genome‐wide SNP genotyping on 337 samples from 15 populations, we validate and refine subspecies classifications, revealing eight genetic clusters and proposing a new subspecies (O. n. ernsti).
