Rumen development is an important factor determining early solid feed intake and performance in cattle. A popular trend towards early weaning of newborn dairy calves necessitated looking for ways of accelerating the gastrointestinal tract (GIT) development. The present study aimed to determine the effect of sodium butyrate (NaB) supplementation in milk replacer and starter diet on rumen develop...

The present study aims at investigating muscle development and stress response in early stages of Siberian sturgeon when subjected to different rearing temperatures, by analysing growth and development of the muscle and by assessing the stress response of yolk-sac larvae. Siberian sturgeon larvae were reared at 16°C, 19°C and 22°C until the yolk-sac was completely absorbed. Sampling timepoints ...

Vertebrate red blood cells (RBCs) display a range of sizes, spanning orders of magnitude in volume in different clades [1]. The importance of this size variation to diffusion during exercise is reinforced by functional links between RBC and capillary diameters [2, 3]. Small RBCs, such as those of mammals (which lack nuclei) and birds, contribute to shorter diffusion distances and permit relativ...

The aim of the present study was to evaluate bone loss at implants connected to abutments coated with a soda-lime glass containing silver nanoparticles, subjected to experimental peri-implantitis. Also the aging and erosion of the coating in mouth was studied. Five beagle dogs were used in the experiments. Three implants were placed in each mandible quadrant: in 2 of them, Glass/n-Ag coated abu...

PURPOSE To evaluate bone healing in the extraction socket of the feline mandibular canine tooth after grafting. METHODS Eighteen adult cats were submitted to unilateral extraction of mandibular canine tooth and divided into three groups. In group 1 (n=6), control, the extraction socket was left empty. In group 2 (n=6), the extraction socket was filled with autogenous cancellous bone from the ...

Objective: To evaluate whether treatment with L-arginine influences the healing of skin flaps in rats exposed to nicotine. Methods: 40 male Wistar rats weighing 142.4 ± 10.1 g were separated into four groups: GC: treatment with 7.4 pH phosphate buffer, submitted to skin flap and observation for ten days; GN: exposure to nicotine for four weeks, submitted to skin flap and observation for ten day...

OBJECTIVES To examine the proportions of type 1 and type 2 muscle fibres and the degree of muscle fibre atrophy and hypertrophy in patients with chronic fatigue syndrome in relation to lactate responses to exercise, and to determine to what extent any abnormalities found might be due to inactivity. METHODS Quadriceps needle muscle biopsies were obtained from 105 patients with chronic fatigue ...

PURPOSE To evaluate the application of the maxillofacial miniplate 1.5 in the repair of unilateral mandibular osteotomies in cats. METHODS Twelve adult cats were divided into two groups. In group 1 (n=6), the osteotomy was performed in the body of the mandible, behind the 1(st) molar. In group 2 (n=6), the osteotomy was performed between the 4(th) premolar and 1(st) molar. The osteotomy was f...
