Exploring the impacts of fescue toxicosis on the pulmonary arterial pressure of angus cows.

Vasoconstriction of peripheral blood vessels is one of the hallmark symptoms of fescue toxicosis in cattle. Thus, it was hypothesized that exposure to ergot alkaloids would increase the pulmonary arterial pressure (PAP). The objectives of this study were to examine the relationship between PAP and different physiological parameters of cows grazing either endophyte-infected (EI) or novel-endophyte (EN) fescue, then evaluate changes in PAP and other physiological measurements in cows exposed to EI pastures and deemed as susceptible or tolerant based on animal performance.

Virtually delivered Mindfulness-Oriented Recovery Enhancement (MORE) reduces daily pain intensity in patients with lumbosacral radiculopathy: a randomized controlled trial.

Introduction: Lumbosacral radiculopathy (LR), also known as sciatica, is a common type of radiating neurologic pain involving burning, tingling, and numbness in the lower extremities. It has an estimated lifetime prevalence as high as 43%.

Objectives: The objective of this randomized controlled trial was to evaluate the impact of virtually delivered Mindfulness-Oriented Recovery Enhancement (MORE) on patients with LR during the COVID-19 pandemic.

Protocol for mindfulness-oriented recovery enhancement (MORE) in the management of lumbosacral radiculopathy/radiculitis symptoms: A randomized controlled trial.

Introduction: Lumbosacral radiculopathy/radiculitis (LR) or "sciatica" is a commonly intractable sequelae of chronic low back pain (LBP), and challenges in the treatment of LR indicate that persistent pain may have both mechanical and neuropathic origins. Mindfulness-based interventions have been demonstrated to be effective tools in mitigating self-reported pain in LBP patients. This paper describes the protocol for a randomized controlled trial (RCT) evaluating the effects of the specific mindfulness-based intervention Mindfulness-Oriented Recovery Enhancement (MORE) on LR symptoms and sequelae, including mental health and physical function.

Autophagy modulates endothelial junctions to restrain neutrophil diapedesis during inflammation.

The migration of neutrophils from the blood circulation to sites of infection or injury is a key immune response and requires the breaching of endothelial cells (ECs) that line the inner aspect of blood vessels. Unregulated neutrophil transendothelial cell migration (TEM) is pathogenic, but the molecular basis of its physiological termination remains unknown. Here, we demonstrated that ECs of venules in inflamed tissues exhibited a robust autophagic response that was aligned temporally with the peak of neutrophil trafficking and was strictly localized to EC contacts.

Influence of weaning strategy on behavior, humoral indicators of stress, growth, and carcass characteristics.

Weaning is one of the most stressful events a calf experiences in our current beef production system. Its effects may include reduced feed intake, increased activity, slower growth, and increased susceptibility to disease. This study was designed to evaluate weaning after a 7-d placement of nose flaps at 7 mo (, = 40) and delaying weaning by 49 d relative to 7-mo weaning (, = 39) as alternatives to the industry standard; abrupt weaning at 7 mo of age (, = 39).
