Bovine tuberculosis is an important zoonotic infectious disease that presents a risk to human health, livestock, and wildlife. We report the complete genome sequence of a new strain that caused a bovine tuberculosis outbreak on a cattle farm in Saskatchewan, Canada, in 2023.

Article Synopsis
  • Oxylipins, which are lipid mediators derived from fatty acids, play crucial roles in respiratory health, but their profiles in lung structural cells are not fully understood.
  • The study measured 162 oxylipins in airway smooth muscle, lung fibroblasts, and epithelial cells, both at baseline and after exposure to various stimuli.
  • Results showed that airway smooth muscle and lung fibroblasts had similar oxylipin profiles dominated by CYP450 metabolites, while epithelial cells had a unique profile rich in COX-derived oxylipins, with distinct changes noted upon stimulation that could impact respiratory function.

Acute electrical stimulation of the common peroneal nerve (cPNS) has been shown to cause an immediate reduction in systolic blood pressure (SBP) in spontaneous hypertense rats (SHR), but the effect of this treatment in sub-chronic ambulatory SBP is unknown. Here we developed an implantable wireless WNClip neural stimulator to test the efficacy of 5-week cPNS as a treatment for hypertension. Daily cPNS 2 Hz monophasic stimulation at threshold for 8 minutes every day for five weeks, reduced SBP in WKY animals by -4 mm Hg, and in SHR animals by -21 mmHg in week 5 (p < 0.

Summary: Machine learning-derived embeddings are a compressed representation of high content data modalities. Embeddings can capture detailed information about disease states and have been qualitatively shown to be useful in genetic discovery. Despite their promise, embeddings have a major limitation: it is unclear if genetic variants associated with embeddings are relevant to the disease or trait of interest.
