nanoparticles of silver were treaeted as clinical trials in some broiler farms for its disinfecting characters in 4 broiler farms during growing period. the nanosilver were used orally and inhalatory in amount of 2 -4 ppm and 40 ppm respectively. some samples of breast muscle, femora muscle, heart, gizzard, liver, skin, spleen, lung, kidney and cloacal feces were collected randomly in slaughter...
poultry nutrition or inappropriate treatments by antibiotics can lead to production of eggs with antibiotic residues. the aim of the present study is to assess the prevalence of drug residues in eggs presented in kermanshah, iran. for this purpose, 120 eggs with the average weight of 60 grams were collected randomly from the supermarkets in kermanshah and later were tested for antibiotic residu...
Introduction: Human Serum Albumin (HSA) is one of the most important proteins in blood that can bind a wide range of components and different drugs such as Warfarin and is also circulated in the body by HSA. Therefore, studying HSA is very significant in pharmacology. In this research, dynamic behavior of residues of Warfain binding site of HSA has been investigated. Methods: Firstly, PDB form...
مروری برآلودگی فراورده های غذایی با منشا دامی به باقی ماندههای آنتی بیوتیکی طی سه دهه اخیر در ایران
Antibiotics residues in animal derived food products are a great concern for public health. The major risk associated with this problem is drug resistance in pathogenic bacteria in consumers.This survey is a comprehensive review of many studies carried out by scientists in Iran in food hygiene, livestock breeding and toxicology over the last thirty years. Food samples were examined by different...
Introduction: The presence of antibiotic residues in food products of animal origin, especially milk and meat, and their consumption can cause serious side effects for human health. The purpose of this study was to monitor antibiotics residues in raw and pasteurized milk produced in Elam province of Iran during the spring and summer of 2012. Material and Methods: For this purpose, 9 industrial ...
the chemical composition, ruminal degradability parameters, ruminal and post ruminal digestibility of saffron residues were determined using in situ and in vitro (gas production) methods. the harvested residues at late vegetative phase were compared with the residues harvested at the early dormant phase. the results showed that ndf and adf concentration of harvested residues at early dormant ph...
All US government pesticide residue datasets show that persistent organochlorine (OC) insecticide residues are surprisingly common in certain foods despite being off the market for over 20 years. Residues of dieldrin, in particular, pose substantial risks in certain root crops. About 60% of the samples of organic vegetables found to contain pesticides are contaminated with OCs. Government regul...
Proficiency test results from 5 countries involving 61 separate interlaboratory proficiency tests for pesticide residues were examined in this study. A total of 24 different matrixes and 869 relative standard deviations of the mean (or median) pesticide residue concentration were statistically evaluated in relation to the Horwitz function. The aim was to determine whether or not the concentrati...
The toxicological significance of exposures to synthetic chemicals is examined in the context of exposures to naturally occurring chemicals. We calculate that 99.99% (by weight) of the pesticides in the American diet are chemicals that plants produce to defend themselves. Only 52 natural pesticides have been tested in high-dose animal cancer tests, and about half (27) are rodent carcinogens; th...
Probabilistic techniques were used to characterize dietary exposure of consumers to pesticides found in twelve commodities implicated as having the greatest potential for pesticide residue contamination by a United States-based environmental advocacy group. Estimates of exposures were derived for the ten most frequently detected pesticide residues on each of the twelve commodities based upon re...
