[ 1 ] - بررسی غلظت بنزوات و سوربات در مواد غذایی مختلف در آذربایجان شرقی

مقدمه: بنزوات و سوربات برای جلوگیری از رشد میکروارگانیسمها و برای افزایش ماندگاری مواد غذایی در اکثر محصولات غذایی استفادهمیشوند. هدف از این مطالعه ارزیابی وضعیت آلودگی نمونههای موادغذایی به این دو نگهدارنده باا تکنیا میکرواساتررا ماایع – ماایعپرشی و کروماتوگرافی مایع با کارایی بالا بود. بنابراین در بین اقلام غذایی سعی شد که پرمصرفترین آنهاا، همنناین ماواد غاذایی کاهمصرف بنزوات و سوربات در آنها...

[ 2 ] - Solid-Phase Extraction and Simultaneous Determination of Tetracycline Residues in Edible Cattle Tissues Using an HPLC-FL Method

In this assay, edible cattle tissues from local markets of Ardabil, a Province of Iran, were examined for residues of tetracycline antibiotics (tetracycline, oxytetracycline and chlortetracycline). In total, 110 samples of triceps, gluteal muscle, diaphragm, kidney and liver were randomly obtained from the local markets of the city of Ardabil. Solid-phase extraction (SPE) and high-performance l...

[ 5 ] - Effect of Ketotifen and Cyproheptadine on Appetite and Weight Changes in Mice

Ketotifen is a potent, safe and long acting antihistamine that is effective in treatment of asthma and its use is believed to causes weight gain and drowsiness. Cyproheptadine, an antihistamine, has anticholinergic and antiserotonergic effects, and causes increases of the appetite and weight gain. In this study the effects of different doses of ketotifen and/or cyproheptadine on the appeti...

[ 6 ] - Determination of Enrofloxacin and Ciprofloxacin residues in five different kind of chicken tissues by dispersive liquid–liquid microextraction coupled with HPLC

Contamination of food producing animals by veterinary drug residues, particularly quinolones, is an essential issue in food safety that causes increasing concern in consumers. The aim of this study was to investigate the occurrence of enrofloxacin and its main metabolite, ciprofloxacin, in chicken tissue samples slaughtered in Tabriz, Iran. Totally 250 samples including liver, muscle, gizzard, ...

[ 8 ] - A Dispersive Liquid–Liquid Micro–Extraction Technique for the Pre–concentration and Quantification of Vitamin D3 in Milk and Yogurt Samples Using a Non-Aqueous HPLC Method

In present study, a DLLME-HPLC-UV method was developed and validated for the extraction, pre–concentration, and subsequently quantification of vitamin D3 (Vit D3) in milk and yogurt samples. In order to be able to extract Vit D3 from studied samples efficiently, the DLLME procedure was optimized with respect to the parameters affecting the extraction efficacy, w...

[ 10 ] - Protection of renal damage by HMG-CoA inhibitors: A comparative study between atorvastatin and rosuvastatin

Objective(s): Hypercholesterolemia is a common metabolic disorder in developing and developed countries and is associated with the increased rates of chronic kidney disease (CKD). Statin therapy could reduce cholesterol synthesis as well as progression of CKD. Diversity between statins causes variety in pharmacokinetics and pharmacodynamics and also their pleiotropic e...
