1. Ewes of the Booroola x Romney genotype carrying triplet lambs were given fresh forages ad lib. in late pregnancy. In Expt 1, groups of three ewes were given kale (Brassica oleracea), perennial ryegrass (Loliumperenne) or perennial ryegrass (0.75)–barley (0.25). In Expt 2, groups of two or three ewes were given fresh perennial ryegrass and infused into the abomasum with iso-energetic quantities of casein and glucose in a 2 x 2 factorial arrangement. Post-lambing ewe live weights were 40–50 kg. Glucose irreversible loss (GIL) was determined from dilution of D-[U-14C]glucose.2. For ewes given

Resumen
Congenital hyperinsulinism (CHI) characterised by inappropriate secretion of insulin despite low blood glucose can result in irreversible brain damage if not promptly treated. The most common genetic cause of hyperinsulinism is the pathogenic variants in ABCC8 and KCNJ11, causing dysregulated insulin secretion. Rapid testing is crucial for all patients because finding a mutation significantly impacts this condition’s clinical management. We report a rare case of focal CHI after a homozygous KCNJ11 mutation who underwent a selective lesionectomy and required octreotide for euglycaemia.

Increased proportions of CD8+CD28 T cells, seen in HIV infection and aging, correlate with decreased vaccine responsiveness and early mortality. CD28 expression is also lost in chronically stimulated cultures of CD8 T cells as they approach replicative senescence, a state of irreversible cell cycle arrest, associated with shortened telomeres and increased levels of TNFα.

A feeding experiment (47 days) was undertaken to evaluate the role of protein meal supplements for Hereford cows given a low quality subtropical grass hay and suckling calves (mean age 37 � 2.2 days). The rates of supplementation were 0, 5.25, 10.5, 15.75, and 21.0 g pelleted protein meal /kg liveweight W0.75. The consumption of grass hay, and the estimated total metabolizable energy intake (MEI) by cows, were significantly (P < 0.01) increased by supplements of protein meal, and their rate of liveweight loss was reduced (P < 0.01). Unsupplemented cows lost 2.56 kg/day compared with a 0.

In gray matter (GM), anoxia induces prominent extracellular ionic changes that are important in understanding the pathophysiology of this insult. White matter (WM) is also injured by anoxia but the accompanying changes in extracellular ions have not been studied. To provide such information, the time course and magnitude of anoxia-induced changes in extracellular K+ concentration ([K+]o) and extracellular pH (pHo) were measured in the isolated rat optic nerve, a representative central WM tract, using ion-selective microelectrodes.

Resumen
Cancer cachexia is a complex multifactorial syndrome marked by a continuous depletion of skeletal muscle mass associated, in some cases, with a reduction in fat mass. It is irreversible by nutritional support alone and affects up to 74% of patients with cancer—dependent on the underlying type of cancer—and is associated with physical function impairment, reduced response to cancer-related therapy, and higher mortality. Organs, like muscle, adipose tissue, and liver, play an important role in the progression of cancer cachexia by exacerbating the pro- and anti-inflammatory response initially ac

Axonal injury and dysfunction in white matter (WM) are caused by many neurologic diseases including ischemia. We characterized ischemic injury and the role of glutamate-mediated excitotoxicity in a purely myelinated WM tract, the mouse optic nerve (MON). For the first time, excitotoxic WM injury was directly correlated with glutamate release. Oxygen and glucose deprivation (OGD) caused duration-dependent loss of axon function in optic nerves from young adult mice. Protection of axon function required blockade of both α-amino-3-hydroxy-5-methylisoxazole-4-propionic acid (AMPA) and kainate recep

ABSTRACT Anaerobic ammonium oxidation (anammox) is a recently discovered microbial pathway and a cost-effective way to remove ammonium from wastewater. Anammox bacteria have been described as obligate chemolithoautotrophs. However, many chemolithoautotrophs (i.e., nitrifiers) can use organic compounds as a supplementary carbon source. In this study, the effect of organic compounds on anammox bacteria was investigated. It was shown that alcohols inhibited anammox bacteria, while organic acids were converted by them.

Long-term use of the peritoneum as a dialysis membrane results in progressive irreversible dysfunction, described as peritoneal fibrosis. Oxidative stress during peritoneal dialysis has been established in many studies. Generation of reactive oxygen species (ROS) by conventional peritoneal dialysis solutions, regardless of whether produced by high glucose, angiotensin II, or glucose degradation products may be responsible for progressive membrane dysfunction. The well-known antioxidant molecule N-acetylcysteine (NAC) is capable of direct scavenging of ROS. The aim of the present study was to i

Focal ischemia evokes a sudden loss of membrane potential in neurons and glia of the ischemic core termed the anoxic depolarization (AD). In metabolically compromised regions with partial blood flow, peri-infarct depolarizations (PIDs) further drain energy reserves, promoting acute and delayed neuronal damage. Visualizing and quantifying the AD and PIDs and their acute deleterious effects are difficult in the intact animal. In the present study, we imaged intrinsic optical signals to measure changes in light transmittance in the mouse coronal hemi-brain slice during AD generation. The AD was i

Abstract The irreversible loss of expression of the CD28 costimulatory receptor is one of the signature changes in human T cells that are driven to the end stage of replicative senescence by chronic stimulation in cell culture. Besides activation, CD28 is also required for glucose metabolism, stabilization of various cytokine mRNAs, and, importantly, for optimal upregulation of telomerase, the enzyme that stabilizes telomeres. Increased proportions of senescent CD8 T cells are associated with decreased vaccine responsiveness and early mortality in the elderly, and, during HIV disease, with mor

In contrast, encapsulating peritoneal sclerosis is a life threatening and usually irreversible condition, associated with bowel obstruction, malnutrition and death. It is unknown whether common etiological factors underlie the development of these 2 clinically and pathologically distinct forms of peritoneal sclerosis.

Abstract Mature erythrocytes are unable to synthesize AMP from IMP due to the developmental loss of adenylosuccinate synthetase, which also effectively prevents the synthesis of adenine nucleotides from circulating hypoxanthine, the major salvageable purine compound. Consequently, AMP deaminase (AMPD) activity must be tightly regulated in order to avoid irreversible depletion of the erythrocyte adenine nucleotide pool during periods of energy imbalance. However, increased intracellular calcium promotes activation of erythrocyte AMPD (AMPD3) through a protein-protein interaction with calmodulin

In wheat (Triticum aestivum L.) drought-induced pollen sterility is a major contributor to grain yield loss and is caused by the downregulation of the cell wall invertase gene IVR1. The IVR1 gene catalyses the irreversible hydrolysis of sucrose to glucose and fructose, the essential energy substrates which support pollen development. Downregulation of IVR1 in response to drought is isoform specific and shows variation in temporal and tissue-specific expression. IVR1 is now prompting interest as a candidate gene for molecular marker development to screen wheat germplasm for improved drought tol
