The use of antibiotics in the preparation of amphibian cell cultures from highly contaminated material.

Antibiotic Resistance of the Isolated Bacteria from Blood Cultures of Cancer Patients

Abstract Background and Objective: One of the main causes of increased mortality in cancer patients is bacteremia. On the other hand, antibiotic resistance is the major cause of treatment failure in malignant diseases especially in hematological malignancies. The aim of this study was to diagnose the bacterial strains isolated from blood specimens of cancer patients and to determine their antib...

جداسازی لیستریا مونوسیتوژن از پنیر با استفاده از روش غنی سازی در سرما و مشاهده باکتری در کشت سلولی هلا

Background: Listeria monocytogenes is frequently transmitted from contaminated food such as cheese, raw vegetables, prepacked salad and etc, to humans. This bacteria can grow inter and extracellular. The aim of this study was to present a simple practical method for isolation of this bacteria from cheese, and detection of it in Hela cell culture by light microscopy Materials and Methods: In ...

گندزدایی آبهای آلوده به کلیفرم مدفوعی با استفاده از ازن: بررسی تاثیر غلظت ازن و زمان تماس

Introduction & Purpose:Chlorine is the most important matter to water disinfection due to a residual effect. But by formation of by-products could be harmful to consumers’ health ,The researchers decided to use the method or other material. For this reason, in this study ozone used to water disinfection and its performance to disinfect of contaminated water with Escherichia coli was investigate...

Preparation of Nitrogen-Doped Graphene By Solvothermal Process as Supporting Material for Fuel Cell Catalysts

Development of efficient electrocatalysts for oxygen reduction reaction (ORR) is one of the most important issues for optimizing the performance of fuel cells and metal-air batteries. The introduction of nitrogen into carbon nanostructures has created new pathways for the development of non-precious electrocatalysts in fuel cells. In this work, nitrogen-doped graphene (NG) was synthesized by a ...
