Background and purpose: Nitrate and nitrite salts to prevent the growth of Çlostridium specie can be added to meat products.Âccording to carcinogenetic properties of this ions, aim of this study was to measurement of nitrate and nitrite content in meat product in Mazandaran. Materials and methods: Â cross sectional study on 42 sample of red Meat Products (sausages with 40% and 60% meat, ha...
angiotensin-ii is a multifunctional hormone that regulates blood pressure, plasma volume, neuronal functions, electrolyte balance, thrust and various other vital mechanisms. it acts through its receptors at 1 and at 2 . the involvement of angiotensin-ii and its receptors in cognition is still ambiguous. therefore, the present study was designed to investigate the effect of angiotensin-ii (2 μg/...
QUESTIONS Is the novel in-vitro diagnostic device U-Test(®) reliable and secure for urine collection in diaper-wearing children and simultaneous evaluation of the urine collected for the presence of leucocytes and nitrite? METHODS The qualitative and functional performance of U-Test(®) was evaluated in a multicentre prospective clinical trial. The diagnostic performance of the novel in-vitro ...
We compared the sensitivity, specificity, and predictive values of the 1-min leukocyte esterase test and the test for urinary nitrite alone and in combination as screening tests for bacteriuria in over 5,000 clinical urine specimens. The leukocyte esterase-nitrite combination had a sensitivity of 79.2%, a specificity of 81%, and a negative predictive value of a negative test of 94.5% for specim...
Background and aims: Nitrite and nitrate are preservatives that have been used in meat products (sausages) and include carcinogenic effects. The aim of this study was determining the mount of nitrite and nitrate in different types of meat products marketed in Kermanshah. Methods: The method of study is descriptive – cross-sectional. 100 samples were taken from meat products factories (19 fact...
We carried out an integrated environmental/biological monitoring program to evaluate cancer hazards among metal industry workers exposed to cutting fluids. Several cutting fluids were sampled according to response to a semiquantitative nitrite rapid test in metal factories in central Italy. The nitrite-positive samples were analyzed for nitrite and nitrosodiethanolamine (NDELA) content and muta...
The nitrite anion is reduced to nitric oxide (NO*) as oxygen tension decreases. Whereas this pathway modulates hypoxic NO* signaling and mitochondrial respiration and limits myocardial infarction in mammalian species, the pathways to nitrite bioactivation remain uncertain. Studies suggest that hemoglobin and myoglobin may subserve a fundamental physiological function as hypoxia dependent nitrit...
background: spinach is one of the vegetables with a high concentration of nitrate which is affected by various processes such as cooking and refrigeration before consumption. the present study aimed to investigate the effect of home cooking method, which has not been studied before, on the level of nitrate and nitrite in spinach. the effect of refrigeration was studied, as well. methods: afte...
