Is Butyrate Concentration in the Equine Gastrointestinal Tract Altered During and After Surgery for Treatment of Large Colon Obstruction?

A major cause of morbidity and mortality in horses with large colon obstructive lesions is injury to the colonic mucosal barrier from ischemic injury. Since butyrate has been shown to play a critical role in the maintenance of a healthy mucosal barrier, it may play a role in the recovery process. This study's objective was to determine whether the differences in butyrate concentrations existed between horses with surgical large colon obstructive lesions and healthy horses both during and after surgery.

Leveraging chromatin state transitions for the identification of regulatory networks orchestrating heart regeneration.

The limited regenerative capacity of the human heart contributes to high morbidity and mortality worldwide. In contrast, zebrafish exhibit robust regenerative capacity, providing a powerful model for studying how to overcome intrinsic epigenetic barriers maintaining cardiac homeostasis and initiate regeneration. Here, we present a comprehensive analysis of the histone modifications H3K4me1, H3K4me3, H3K27me3 and H3K27ac during various stages of zebrafish heart regeneration.

Natural genetic variation quantitatively regulates heart rate and dimension.

The polygenic contribution to heart development and function along the health-disease continuum remains unresolved. To gain insight into the genetic basis of quantitative cardiac phenotypes, we utilize highly inbred Japanese rice fish models, , and . Employing automated quantification of embryonic heart rates as core metric, we profiled phenotype variability across five inbred strains.

SmartWoodID-an image collection of large end-grain surfaces to support wood identification systems.

Wood identification is a key step in the enforcement of laws and regulations aimed at combatting illegal timber trade. Robust wood identification tools, capable of distinguishing a large number of timbers, depend on a solid database of reference material. Reference material for wood identification is typically curated in botanical collections dedicated to wood consisting of samples of secondary xylem of lignified plants.

Critical Care of the Colic Patient: Monitoring, Fluid Therapy, and More.

A successful outcome to management of the critical colic patient is highly dependent on how the patient is monitored and treated, particularly, in the perioperative period. In this article, we will provide an update on monitoring techniques, advances in fluid therapy, nutrition management and pharmacotherapeutic agents, inclusive of pain monitoring and management, prokinetics, and management of systemic inflammatory response syndrome and the hypercoagulable state.
