objective(s): abc transporters comprise a large family of transmembrane proteins that use the energy provided by atp hydrolysis to translocate a variety of substrates across biological membranes. all members of the human abcg subfamily, except for abcg2, are cholesterol-transporter. the aim of this study was to determine the liver, the small intestine and kidney abcg5 relative gene expression i...

Stephanuriosis is a disease of the urinary tract both domestic pigs and wild boars occurring in tropical subtropical regions, with tendency to spread other geographical areas. In endemic areas, occurs more often extensively bred herds, normally nonspecific clinical picture. As result larval stage migrations parasitism adult forms nematode Stephanurus dentatus, damage liver, kidneys, ureters, lu...

An experiment was conducted to evaluate the effect of form and particle size of feed supplemented with L- threonine on growth performance, carcass characteristic and blood biochemical parameters of broiler chickens. The experimental design was a 2 × 2 × 2 factorial arrangement of treatments evaluating two feed forms (pellet or mash), two feed particle sizes (fine or course), and two inclusion r...

The goal of this research was to study the curing behavior and biodegradability DER 736 modified with epoxidized oleic acid. In this paper we demonstrate the efficient epoxidation of oleic acid with performic acid generated in situ from formic acid and hydrogen peroxide in the presence of H2SO4 as catalyst. The highest relative epoxy yield of 61% was achieved at 40 ͦC after 10 h. DER 736 modifie...

I. Weanling (24-d-old) male rats were maintained at their body-weight for I month by restricting the intake of their normal diet. The animals were then rehabilitated for 0, 3 , 7 , 1 0 or 16 d. Control animals weregiven anunrestricted diet and some killed at the same body-weight as the experimental animals and others at the same age. 2. The forebrain, cerebellum, brain stem, heart, lungs, liver...

Ecotoxicological data in reptiles are mainly represented by field studies reporting the tissue burden of wild-captured individuals but much less is known regarding the processes of uptake, depuration, accumulation and the effects of inorganic contaminants in these species. In the present study, the accumulation, the path and the effects of exposure to cadmium (Cd) through diet intake were inves...

The NRC selenium (Se) requirement for broiler chicks is 0.15 μg Se/g diet, based primarily on weight gain and feed intake studies reported in 1986. To determine Se requirements in today's rapidly growing broiler chick, day-old male chicks were fed Se-deficient basal diets supplemented with graded levels of Se (0, 0.025, 0.05, 0.075, 0.1, 0.2, 0.3, 0.5, 0.75, and 1.0 μg Se/g) as Na2SeO3 (5/treat...

Recent epidemiological studies in people whose birth weights were recorded many years ago suggest links between impaired growth during early life and the development of diseases, including diabetes, much later in life. The long-term effects of retarded early growth are proposed to result from malnutrition at critical periods of fetal or infant development leading to reduction in the growth of o...
