[ 1 ] - Effect of sub acute exposure of nano Zinc particles on oxidative stress parameters in rats
BACKGROUND: Zinc (Zn) is one of the most important essential elements in the body of animals and plants. Zinc plays a significant role in the structure of more than 300 different proteins and in many life supporting biochemical and metabolic processes such as cellular respiration and protection against free radicals. Nanoparticles of zinc are the new form of Zinc used in cosmetic and personal c...
[ 2 ] - Toxicity of manufactured copper nanoparticles - A review
The health effects of nanoparticles (NPs) are raising considerable and growing concerns from the public and government around the world. Nano-metals are new forms of metal with special properties, but are characterized by having a particle size of less than 100 nm. Copper is an essential trace element and its deficiency leads to different diseases in humans. In gen...
[ 3 ] - Investigation of hematotoxic effect of nano ZnO, nano Fe3O4 and nano SiO2 in vitro
Objective(s): Evaluation of nanomaterials interaction with blood ingredients is a part of preclinical risk assessment of newly-synthesized materials, especially for nano-sized pharmaceuticals which are intravenously administrated. The red blood cells (RBCs) are susceptible to oxidative stress damage. This study was designed to evaluate induced oxidative hematotoxic effect of na...
[ 4 ] - اندازه گیری باقیمانده نیتریت در انواع فراورده‌های گوشتی عرضه شده در تبریز به روش اسپکتروفتومتریک
نمک‌های نیتریت و نیترات از افزودنی‌های مورد استفاده در فرآورده‌های گوشتی می‌باشند که به عنوان نگهدارنده جهت جلوگیری از رشد باکتری‌های خطرناکی مانند کلستریدیوم بوتولینوم و ایجاد رنگ مطلوب در گوشت کاربرد دارند. استفاده از این نمک‌ها باعث تولید ترکیب نیتروز آمین و افزایش خطر سرطان‌زایی می شود. از این رو میزان مصرف آنها باید در حد استاندارد های مصوب (حداکثر ppm120 برپایه نیتریت) باشد. این مطالعه ت...
[ 5 ] - Investigation on the teratogenic and embryotoxic effects of nanozeolite on chick embryos model
Objective(s): In veterinary medicine, zeolites are used as toxin binder in animal feed, ammonia purification of aquatic pools, animal smell and moisture control. This study investigated on the risk assessment of nano zeolite on development of embryonic chicken models, anomalies, tetratogenic and embryotoxic effects. Methods: Eggs (120 = n) were accidentally di...
[ 6 ] - The Effect of Frying Process on the Level of Malondialdehyde in Different Meat Products
Background: Frying is one of the popular cooking methods for the preparation of food especially meat products. However, this process has some adverse effects, such as lipid oxidation that results in deterioration and rancidity of food during preparation and storage. Malondialdehyde (MDA) as a secondary product of oxidation is commonly used as an index of rancidity in food products. However...
