Calves weaned on cow­calf operations throughout Arkansas even­ tually move on to stocker, feedlot and packer operations. Wide variations in carcass uniformity and consistency exist among these calves. Potential carcass problems can include inappro­ priate carcass size and weight, i nadequate tenderness, insufficient intramuscular fat (marbling) and excess external fat cover. Many of these quali...

METHODS: Immunocompromised nude-mice underwent external beam irradiation of the scalp. Five weeks later, mice either received seven deferoxamine treatments (1mg in 100ul) or saline subcutaneously to the irradiated area every other day. Laser Doppler analysis (LDA) was recorded prior to irradiation, following irradiation, and 24 hours following each treatment. Human fat grafts were then injected...

background and objective : mozzarella is a soft cheese belonging to the pasta filata family, containing 18-24 % fat. the objective of this study was to determine the effect lowering mozarella fat content to 6% and adding whey protein concentrate on the rheological properties of the low-fat cheese. materials and methods : low-fat mozzarella was produced using 3 fat replacers ( dairy-lo, 35% prot...

BACKGROUND Knee osteoarthritis is a major cause of disability in the aging population. Based on pathological, magnetic resonance imaging (MRI) and arthroscopy studies, progressive osteoarthritis involves all tissues of the joint and includes bone marrow lesions, synovial proliferation, fat pad inflammation, and high subchondral bone turnover. Recent research suggests that abnormal perfusion in ...

An opportunity to study pure pancreatic secretion in man is extremely rare. Wohlgemuth (1) reported his observations in a young man with an external pancreatic fistula. He found that the rate of secretion varied considerably with the diet, that no flow was observed with a high fat diet, that there was an increased rate of secretion with Quantitative studies of the composition of the pancreatic ...

The purpose of the study was to investigate the measurement properties of questionnaires associated with the Youth Physical Activity Promotion (YPAP) model. Data were collected from 296 children in Grades 5-8 using several existing questionnaires corresponding to YPAP model components, a physical activity questionnaire, and 6 consecutive days of pedometer data. Internal validity of the question...

The regulation of energy balance involves an intricate interplay between neural mechanisms that respond to internal and external cues of energy demand and food availability. Compelling data have implicated the neurotransmitter dopamine as an important part of body weight regulation. However, the precise mechanisms through which dopamine regulates energy homeostasis remain poorly understood. Her...

The objective of this research was to study the effect of water activity and glass transition temperature on the fat hydrolysis in a food model system. The model system was prepared with tapioca starch, casein, palm oil and sugar as 58, 14, 16 and 12 g/100 g model matrix, respectively. Hydrolysis reaction was accelerated by commercial lipase at six levels of water content and water activity. Mo...

genetic trend for production traits were estimated in iranian holstein cattle using the first lactation data recorded by cattle breeding and dairy product improvement center of the state from 1991 to 2006. effect of some factors on genetic trend was investigated using data from 18 large herds. (co) variance components and genetic parameters were estimated, using five trait animal model and em-a...

BACKGROUND Liposuction is a procedure to reduce the volume of subcutaneous fat by physical force. Intracellular storage fat is composed of triglyceride, whereas circulating fat particles exist as cholesterol or triglycerol bound to carrier proteins. It is unavoidable that the storage form of fat particles enters the circulation system after these particles are physiologically destroyed. To date...
