Abstract The objective of the study was to compare production results andtechnological meat quality for pigs born outdoors and reared indoors or outdoors during the summerperiod. A total of 279 pigs was reared in a large pen on deep litter, or outdoors. Daily weight gainand lean meat percentage were higher for pigs outdoors than indoors during year one (864 vs. 841g;56.9 vs. 55.9%), (more…)

Abstract Blunt carotid artery injuries occur in 0.3% of blunt injured patients and maylead to devastating neurological consequences. However, arterial mechanics leading to internallayer subfailure have not been quantified. Twenty-two human carotid artery segments and 18 porcinethoracic aorta segments were opened to expose the intimal side and longitudinally distracted tofailure. (more…)

Abstract It is believed that some Finnish farmed “Wild Boars” may not originate fromgenuine European Wild Boar. To test this the D-loop mitochondrial sequence and nuclearglucosephosphate isomerase processed pseudogene (GPIP) and melanocortin receptor 1 (MC1R) genes wereanalysed in 41 Finnish farmed Wild Boar from two farms in order to determine if there was anyevidence of hybrid origins.

Contributions of the active and passive components of the cytoskeletalprestress to stiffening of airway smooth muscle cells.

Rosenblatt,N; Hu,S; Suki,B; Wang,N; Stamenovic,D

Abstract Airway smooth muscle cells exhibit stiffening during contractile activation.This stiffening may be interpreted as a result of the stabilizing influence of the mechanicalprestress stored within the cytoskeleton (CSK). However, in vivo, airway smooth muscle cellscontract while simultaneously experiencing breathing-induced stretching. Excessive stretching ofcells could cause actin-myosin crosslinks, and possibly other cytoskeletal filaments, (more…)

Abstract Print and broadcast journalists follow a general set of guidelines in deciding what to report. This article shows how you can increase your chances of drawing media attention simply by understanding and using the system. A fictional certifid personal trainer with a new business called Train with Wayne manages to catch the eye of the media. (more…)

Hahn,MS; McHale,MK; Wang,E; Schmedlen,RH; West,JL

Abstract Mechanical conditioning represents a potential means to enhance thebiochemical and biomechanical properties of tissue engineered vascular grafts (TEVGs). (more…)

A Nutritionist’s View

March 11, 2008 By: admin Category: Health Sciences, Pharmacology, Toxicology and Pharmaceutical Science

Abstract Many athletes do not know the importance of hearty eating to achieve their maximum performance. Add to this gastrointestinal problems that many experience, and the outcome is likely to be a diet with not enough of the right foods at the right time (more…)

The impact of breathing pattern and lung size on the alcohol breath test

March 11, 2008 By: admin Category: Health Sciences, Veterinary Medicine

Hlastala,MP; Anderson,JC

Abstract Highly soluble gases exchange primarily with the bronchial circulationthrough pulmonary airway tissue. Because of this airway exchange, the assumption that end-exhaledalcohol concentration (EEAC) is equal to alveolar alcohol concentration (AAC) cannot be true. Duringexhalation, (more…)
