The current study was undertaken to investigate the effect of feeding diets varying in sugar concentration to postpartum transition cows on productivity, ruminal fermentation, and nutrient digestibility. We hypothesized that the high-sugar diet would increase dry matter intake and lactation performance. The secondary objective was to characterize changes in ruminal fermentation and nutrient dig...

BACKGROUND Delayed onset muscle soreness (DOMS) occurs after unaccustomed exercise and has been suggested to be attributable to reactive oxygen species (ROS). Previous studies have shown increased ROS after lengthening contractions, attributable to invading phagocytes. Plasma glucose is a vital fuel for phagocytes, therefore carbohydrate (CHO) status before exercise may influence ROS production...

The neutral lipids of Acholeplasma axanthum contain carotenoid pigments, as evidenced by spectral characteristics, visual color, color reactions, and labeling with [2-14C-A1mevalonic acid. Approximately 80% of the label from [2-14C]mevalonic acid appeared in esterified fatty acids of the glycolipids and polar lipids. These carboxylic acids behaved as hydroxy acids of varying chain length.

Mycobacterium bovis BCG produces a variety of methyl-branched fatty acids. They include C28 to C32 mycocerosic acids esterified to phthiocerol and phenolphthiocerol and the shorter (C22 to C26) mycocerosic acids esterified to phthiocerol. A mycocerosic acid synthase gene-disrupted mutant was still able to produce the shorter mycocerosic acids. The enzyme short chain mycocerosic acid synthase (S...

A simplified scheme of analysis is presented for the determination of free and esterified cholesterol, the phospholipids, and the neutral fats (triglycerides) of blood serum. The hydroxamic acid reaction is used to determine total esterified fatty acids. The phospholipids are determined after acid digestion of a trichloroacetic acid precipitate of protein-phospholipid, and both total and free c...

A highly purified lipase was prepared from the particulate fraction of rat adipose tissue. Although the lipase catalyzes the hydrolysis of diglycerides and triglycerides of both long and short chain fatty acids, monoglycerides are not hydrolyzed. The enzyme has a marked specificity toward fatty acids esterified to the primary hydroxyl groups and hydrolyzes a,-diglycerides 10 times more rapidly ...

Bovine heart cytochrome-c oxidase was reconstituted in liposomes (asolectin) and the activity measured in the presence and absence of uncoupler at increasing concentrations of non-esterified fatty acids. Palmitic and stearic acids resulted in a decrease of about 40% in the respiratory control ratio at a concentration of 1 microM, when measured using a spectrophotometric procedure but not with a...

Background: Cardiovascular disease (CVD) is the leading cause of mortality worldwide. Omega-3 fatty acids have been shown to have both anti-atherogenic and anti-inflammatory effects through inducing the expression and production of adipokines. Adipokines such as apelin, have been observed to play a protective role in the incidence and progression of CVD. The aim of this study was to assess the ...

the aim of the study was to investigate the improving effect of garcinia cambogia extract on performance metrics, and serum non-esterified fatty acids (nefa) and c-reactive protein (crp) levels in rats fed with atherogenic diet. thirty, one-year-old, female sprague-dawley rats were randomly assigned to threeexperimental groups of ten animals each. control group was fed with basal diet (2% liqui...
