1. Echotextural characteristics of the mammary gland during early lactation in two breeds of sheep varying in milk yields
Abstract The main goal of this preliminary study was to determine and compare ultrasonographic characteristics of the mammary gland in two genotypes of ewes varying in milk productivity at 2, 3 and 4 weeks after lambing. Ultrasonographic images of the udder were obtained using the 5.0- and 7.5-MHz transducers, in axial and coronal planes, in four low milk-yi

2. IMUNOMARCAÇÃO DE TGF-β EM PRÓSTATAS CANINAS NORMAIS E COM LESÕES PROLIFERATIVAS
Resumo O fator de crescimento transformador-β (TGF-β), um mediador do crescimento prostático, induz a angiogênese e inibe a proliferação celular. Neste estudo, esse marcador foi utilizado com o objetivo de avaliar sua imunomarcação no tecido normal e com lesões proliferativas benignas, pré-neoplásicas e neoplásicas da próstata canina. Para isso,

3. Effects of in ovo injection of lysine and methionine into fertile broiler (parent stock) eggs on hatchability, growth performance, caecum microbiota, and ileum histomorphology
ABSTRACT We investigated the effect of in ovo injection of lysine, methionine, or their mixture into fertile broiler eggs on hatchability, chick weight, growth performance, inner organ development, caecum total aerobic bacteria, E. coli, coliforms, Enterobactericaea, and ileal histomorphology of broilers. Three hundred fertile eggs obtained from 60-week-old

4. Breed and Sex Differences in the Gross Anatomy, Digesta pH and Histomorphology of the Gastrointestinal Tract of Gallus Gallus Domesticus
ABSTRACT A study was conducted to investigate the influence of breed and sex in the gross anatomy, digesta and histology of Ross 308 broiler and Venda chickens. Chickens were slaughtered at 90 days of age and the pH of the digestive organs was measured immediately after slaughter. The digestive organ weights and lengths of Ross 308 broiler and Venda chickens

5. Effect of Zinc Level and Source (Zinc Oxide Vs. Zinc Glycine) on Bone Mechanical and Geometric Parameters, and Histomorphology in Male Ross 308 Broiler Chicken
ABSTRACT The aim of this study was to evaluate the effect of adding zinc (Zn) mineral supplements from organic (ZnGly) and inorganic (ZnO) sources to growing male Ross 308 chickens on the mechanical, geometric, and histomorphometrical parameters of long bones. A corn-soybean meal basal diet was supplemented with Zn at 50 or 100 mg·kg-1 of a premix, except t

6. Hydrogen sulfide in posthemorrhagic shock mesenteric lymph drainage alleviates kidney injury in rats
Posthemorrhagic shock mesenteric lymph (PHSML) is a key factor in multiple organ injury following hemorrhagic shock. We investigated the role of hydrogen sulfide (H2S) in PHSML drainage in alleviating acute kidney injury (AKI) by administering D,L-propargylglycine (PPG) and sodium hydrosulfide hydrate (NaHS) to 12 specific pathogen-free male Wistar rats with

7. Exogenous normal lymph alleviates lipopolysaccharide-induced acute lung injury through lessening the adhesion molecules
PURPOSE: To evaluate the role of exogenous normal lymph (ENL) on lipopolysaccharide (LPS)-induced acute lung injury (ALI) in rats.METHODS:ALI was induced by the jugular vein injection of LPS (iv, 15 mg/kg) in rats of the LPS and LPS+ENL groups within 15 min, then, ENL without cell components (5 ml/kg) was infused at the speed of 0.5 ml per minute in the LPS+

8. Exogenous normal lymph reduces liver injury induced by lipopolysaccharides in rats
The liver is one of the target organs damaged by septic shock, wherein the spread of endotoxins begins. This study aimed to investigate the effects of exogenous normal lymph (ENL) on lipopolysaccharide (LPS)-induced liver injury in rats. Male Wistar rats were randomly divided into sham, LPS, and LPS+ENL groups. LPS (15 mg/kg) was administered intravenously v

9. The effect of n-acetylcysteine on hepatic histomorphology during hypothermic preservation
PURPOSE: To evaluate the NAC effects on liver hypothermic preservation at different time intervals. METHODS: For this, we used livers of male Wistar rats weighing between 250 and 300g, undergoing preservation in Ringer solution at 4°C for up to 24 hours. Tissue samples were obtained at four moments of preservation for histological examination by hematoxyli

10. Ischemic preconditioning attenuates remote pulmonary inflammatory infiltration of diabetic rats with an intestinal and hepatic ischemia-reperfusion injury
PURPOSE: To assess ischemic preconditioning (IPC) effects in pulmonary lesion in intestinal and hepatic ischemia-reperfusion (IR) injury models using diabetic rats. METHODS: Diabetes (DM) was induced in 28 male Wistar rats by alloxan (42 mg/kg, IV). After 28 days, severe DM rats were submitted to intestinal or hepatic IR injury with or without IPC. Intestina

11. The termal influence on the dynamics of cell membranes: a contribution to the conservation of Steindachneridion parahybae (Siluriformes: Pimelodidae), a threatened species of fish / A influência térmica na dinâmica das membranas celulares: uma contribuição na conservação de Steindachneridion parahybae (Siluriformes: Pimelodidae), uma espécie de peixe ameaçada de extinção
Temperature is the most important environmental factor affecting the activity of ectothermic animals such as fish. Compensatory adjustments to temperature occur with time courses ranging from less than a minute to more than a month, and membranes are the first targets affected by change of temperature, and their lipid components respond immediately to this c

12. VINHO TINTO, SUCO DE UVA E ETANOL EM RATOS ADULTOS SUBMETIDOS À DIETA HIPERLIPIDÊMICA
Special attention has been focused on protection against diseases associated with oxidative stress such as cancers, diabetes, cardiovascular diseases, aging and neurodegenerative disease in the last years. Previous reports indicate that highcholesterol diets induced oxidative stress and hypercholesterolemia in rats. Some dietary compounds such as polyphenols
