We investigated the effects of high protein intake on host resistance to Paracoccidioides brasiliensis. Two-d fasted mice were infected with P. brasiliensis and refed on diets with three different levels (54%, 20%, and 5%) of casein. The mice refed the 54% casein diet showed reduced antifungal activity in the spleen and liver as compared with the mice refed the 5% or the 20% casein diet. After ...
The purpose of this work was to assess the quality of pacu (Piaractus mesopotamicus) and tambaqui (Colossoma macropomum) gutted and stored on ice for a period of 19 days. Color, texture, pH, acid value, peroxide value, thiobarbituric acid reactive substances, total volatile bases and counts of aerobic mesophilic heterotrophic and psychrotrophic bacteria assessments were performed in the meat of...
INTRODUCTION Salivary TBARS are a potential marker of oxidative stress in the oral cavity. Previous studies have found increased levels of salivary TBARS in various diseases. The aim of this study was to assess the variability of salivary TBARS in both genders. SUBJECTS & METHODS Saliva samples from thirty-eight healthy volunteers (18F & 20M) were collected every day during 30 day period. TBA...
The paper covers the study of the effects of silver (Ag) and copper (Cu) nanoparticles on wheat-Pseudocercosporella herpotrichoides pathosystem in general and, separately, on their interaction both with the plant and with the pathogen. Plants, treated with nonionic colloidal solutions of biogenic metal nanoparticles of Ag and Cu, have taken seed treatment as stress and have demonstrated the sam...
This study investigated whether an acute session of high-intensity interval training (HIIT) is sufficient to alter lymphocyte function and redox status. Sixteen young healthy men underwent a HIIT session on a cycloergometer, consisting of eight bouts of 1 min at 90-100% of peak power, with 75 seconds of active recovery at 30 W between bouts. Venous blood was collected before, immediately after,...
The binuclear zinc(II) complex, [Zn2(HPTP)(CH3COO)]2+ was found highly active to cleave DNA (double-strand super-coiled DNA, pBR322 and phix174) in the presence of hydrogen peroxide. However, no TBARS (2-thiobarbituric acid reactive substance) formation was detected in a solution containing 2-deoxyribose (or 2'-deoxyguanosine, etc); where (HPTP) represents N,N,N'-N'-tetrakis(2-pyridylmethyl)-1,...
The studies were undertaken on examining the influence of different linoleic/linolenic acid ratios in the diet of pregnant cows on some parameters which are involved in metabolism of prostaglandins in their placentas. Phospholipase A2 (PLA2) which provides arachidonic acid (AA), superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) the two being involved in neutralization of reactive oxyg...
Studies have shown that reactive oxygen metabolites and lipid peroxidation play important roles in ischemia-reperfusion injury in many organs such as heart, brain and stomach. The aim of this study is to evaluate the antioxidant effect of L-carnitine on gastric mucosal barrier, lipid peroxidation and the activities of antioxidant enzymes in rat gastric mucosa subjected to ischemia-reperfusion i...
