Recognition of lameness and decisions to catch for inspection among sheep farmers and specialists in GB [PDF]

, 2008
Background: Epidemiological studies have used farmer estimates of the prevalence of lameness in their flocks. This assumes that farmers can identify lame sheep.

Pyrazole‐Derived Antibacterial Compounds Effectively Treat Methicillin‐Resistant Staphylococcus Aureus Infections by Inhibiting Aspartate Transcarbamoylase

Advanced Science, EarlyView.
This study unveils a novel antibacterial mechanism against MRSA, in which the compound Py‐27 selectively targets and inhibits aspartate transcarbamoylase (ATCase), a key enzyme in pyrimidine synthesis. This inhibition disrupts DNA replication, induces oxidative damage, leading to potent bactericidal activity.

Heat Stress Promotes Fibroblast‐Derived WNT5A Secretion Through m6A Modification to Activate Melanogenesis

Advanced Science, EarlyView.
Heat stress promotes WNT5A secretion from fibroblasts via METTL3/YTHDC1‐dependent m6A methylation. Subsequently, WNT5A binds to FZD10 on melanocytes, activating β‐catenin‐driven melanogenesis. ABSTRACT As the impact of global warming continues to intensify, the effects of heat stress on the skin are becoming increasingly evident.

Gene expression profiling en association with prion-related lesions in the medulla oblongata of symptomatic natural scrapie animals. [PDF]

, 2011
The pathogenesis of natural scrapie and other prion diseases remains unclear. Examining transcriptome variations in infected versus control animals may highlight new genes potentially involved in some of the molecular mechanisms of prion-induced ...

Performance Estimation and Ex Vivo Validation of Untethered Magnetic Robots in Soft Tissue

Advanced Science, EarlyView.
This study presents an empirical model that quantitatively predicts the step‐out frequency of screw‐type untethered magnetic robots (UMRs) in soft viscoelastic environments, including ex vivo brain tissue. By integrating key parameters into a dimensionless framework, the model enables estimation of robot performance across a range of biological ...

m6A‐Driven Pexophagy Triggers Placental Ferroptosis to Impair Fetal Growth Upon Environmental Stress

Advanced Science, EarlyView.
Prenatal environmental stress exposure promotes m6A modification to drive PEX2‐dependent pexophagy, thereby causing placental ferroptosis and FGR. ABSTRACT The role and underlying mechanisms of placental ferroptosis in fetal growth restriction (FGR) induced by environmental stress remain poorly understood.

Helicobacter pylori‐Induced Persistent IGF2BP1 Activation Promotes Ferroptosis Resistance in Gastric Tumorigenesis

Advanced Science, EarlyView.
Helicobacter pylori infection induces sustained upregulation of the RNA‐binding protein IGF2BP1 in gastric epithelial cells, establishing a persistent epitranscriptomic program. IGF2BP1 stabilizes SLC7A11 mRNA in an m6A‐dependent manner to suppress ferroptosis and promote epithelial survival under oxidative stress. Pharmacological inhibition of IGF2BP1

Experimental poisoning by Enterolobium contortisiliquum in sheep

Pesquisa Veterinária Brasileira
: Ingestion of Enterolobium contortisiliquum pods causes digestive disturbances, secondary hepatogenous photosensitization and abortions in ruminants. Pods were administered to sheep via a ruminal cannula to characterize acute poisoning. In Experiment 1,

Variability in disease phenotypes within a single PRNP genotype suggests the existence of multiple natural sheep scarpie strains within Europe [PDF]

, 2010
Variability of pathological phenotypes within classical sheep scrapie cases has been reported for some time, but in many instances it has been attributed to differences in the PRNP genotype of the host.
