A characterization of inflammatory and structural markers within the rumen epithelium during grain-induced ruminal acidosis in lactating dairy cattle
Download2012
Steele, Michael A., Plaizier, Jan C., AlZahal, Ousama, Dionissopoulos, Louis, McBride, Brian W.
The objective of this study was to characterize the mRNA and protein expression of inflammatory and structural genes in the rumen epithelium during grain-induced ruminal acidosis in lactating dairy cattle. A total of 16 rumen-fistulated, lactating Holstein dairy cattle (618±35 kg of body weight,...

Adaptation to high grain diets proceeds through minimal immune system stimulation and differences in extracellular matrix protein expression in a model of subacute ruminal acidosis in non-lactating dairy cows

AlZahal, Ousama, McBride, Brian W., Dionissopoulos, Louis, Steele, Michael A.
Problem statement: Subacute Ruminal Acidosis (SARA) is a metabolic disorder affecting approximately 20% of all dairy cattle in North America. Although the presence of SARA has been described for some time, the etiology of the disorder remains uncertain. For example, many animals diagnosed with...

Altered ganglioside metabolism in inflammatory bowel disease and the impact of dietary ganglioside intake
DownloadFall 2014
Gangliosides are integral to the structure and function of the plasma membrane. Ganglioside composition of the small intestinal brush border membrane and apical surface of the colon influence numerous cell processes including microbial attachment, cell division, differentiation, and signaling....

Crohn’s disease (CD) is one of the chronic inflammatory bowel diseases (IBD) with a complex etiology involving genetic factors, priming by enteric microflora, environmental factors and a change in the immune-mediated response, the other IBD is ulcerative colitis. The diagnosis of CD has...

Cardiovascular diseases (CVD) such as myocardial infarction and stroke are a major cause of morbidity and mortality worldwide. Impairment of the normal vasorelaxant functions of the vascular endothelium, termed endothelial dysfunction; appear to underlie the pathogenesis of CVD. Endothelial...

Abstract: Introduction: Partial bladder outlet obstruction (pBOO) is a ubiquitous problem that results in renal damage. We hypothesize that change in the bladder progresses over time. Methods: Fischer rats underwent surgical pBOO for 2, 4, 8, or 13 weeks and were compared to shams. Urodynamic...

Chronic systemic inflammatory conditions, such as atherosclerosis, diabetes and obesity are associated with increased risk of stroke, which suggests that systemic inflammation may contribute to the development of stroke in humans. The hypothesis that systemic inflammation may induce brain...

Butyrate-mediated genomic changes involved in the non-specific host defenses, matrix remodelling and the immune response in the rumen epithelium of cows afflicted with subacute ruminal acidosis
Download2013
Steele, Michael A., Greenwood, Sabrina L., Plaizier, Jan C., McBride, Brian W., Matthews, James C., Laarman, Anne H., AlZahal, Ousama, Dionissopoulos, Louis
Subacute Ruminal Acidosis (SARA) is a disorder in cattle which can lead to chronic inflammation in the rumen epithelium, known as rumenitis. Butyrate has been shown to attenuate some of the detrimental effects of inflammatory gastroenteral disorders but the molecular mechanisms mediated by...

Changes in the rumen papillae during the periparturient transition in Holstein dairy cows are accompanied by changes in abundance of proteins involved in intracellular pH regulation, but not SCFA transport

McBride, Brian W., Laarman, Anne H., Steele, Michael A., AlZahal, Ousama, Kleinberg, Adam
The objective of this study was to examine changes in SCFA transportcapacity in the rumen epithelium during the parturition transition period.Twelve pregnant, cannulated primiparous and multiparous cows were fed astandard Total Mixed Ration (TMR) for the duration of the dry period; aftercalving,...

Characterization of Spinal Cord Microglia. Previous studies suggest that the functional response properties of activated brain microglia varied according to the brain region they were derived from, suggesting that these activation profiles are a function of their local environment. CNS microglia...
