Effects of interesterified lipid design on the short/medium chain fatty acid hydrolysis rate and extent (in vitro).

Short/medium chain fatty acids have well known health effects such as gut immune regulation and ketogenesis. The ability to realise these health effects is potentially limited by their rapid gastro-intestinal lipolysis. It was proposed that synthesising novel interesterified lipids via an interesterification reaction to generate a combination of short/medium and long chain fatty acids would modulate their gastrointestinal digestion.

Hierarchically structured phase separated biopolymer hydrogels create tailorable delayed burst release during gastrointestinal digestion.

The on demand delivery of novel peptide actives, traditional pharmaceuticals, nutrients and/or vitamins is a ever present challenge due to the digestive and metabolic degradation of the active and the delivery vehicle. Biodegradable biopolymer hydrogels have long held promise as candidates for creating tailored release profiles due to the ability to control gel porosity. The present study describes the creation of novel hierarchical biopolymer hydrogels for the controlled release of lipids/lipophilic actives pharmaceutical ingredients (APIs), and mathematically describes the mechanisms that affect the timing of release.

Zoonotic Potential and Antibiotic Resistance of Escherichia coli in Neonatal Calves in Uruguay.

Escherichia coli is one of the main etiological agents of neonatal calf diarrhea (NCD). The objective of this study was to assess the presence of virulence genes, genetic diversity, and antibiotic resistance mechanisms in E. coli associated with NCD in Uruguay.

Prevalence of Escherichia coli adhesion-related genes in neonatal calf diarrhea in Uruguay.

Introduction: Neonatal calf diarrhea (NCD), one of the most important diseases of neonatal dairy and beef calves in Uruguay, has become relevant in association with intensive systems. This disease generates substantial economic losses every year worldwide as a result of increased morbidity and mortality. Escherichia coli, one of the pathogens associated with NCD, can express several fimbrial and afimbrial adhesins.
