ABSTRACT: Candidiasis is a fungal infection caused by Candida albicans. Allium sativum (garlic) and Curcuma longa (turmeric) have been used as antifungal agents. The main aim of this study was to identify the effectiveness of these natural products towards C. albicans and on their pharmacological and toxicity aspects. Thus, agar disc diffusion method was used to study the antifungal activity of...

Adult female western flower thrips (Frankliniella occidentalis) were exposed 12-24h to bean (Phaseolus vulgaris) and impatiens (Impatiens wallerana) leaf disks treated with Beauveria bassiana conidia and then transferred to clean bean or impatiens at various times post-treatment. Significantly greater levels of fungal infection were observed when thrips were treated on bean versus impatiens, bu...

Soil contamination by silver nanoparticles (AgNP) is of potential environmental concern but little work has been carried out on the effect of such contamination on ectomycorrhizal fungi (EMF). EMF are essential to forest ecosystem functions as they are known to enhance growth of trees by nutrient transfer. In this study, soil was experimentally contaminated with AgNP (0, 350 and 790 mg Ag/kg) a...

The presence of autoreactive CD4(+) T cells in the peripheral blood of healthy human subjects was investigated after removal of CD4(+)CD25(+) regulatory T cells (Treg). CD4(+) T cells that were directed against the type 1 diabetes-associated autoantigen glutamic acid decarboxylase 65, the melanocyte differentiation Ag tyrosinase, and the cancer/testis tumor Ag NY-ESO-1 were readily derived from...

Background: In 1997, a novel DNA virus was isolated from the serum of a patient in Japan, and it was named TT virus (TTV). As the virus is replicated in liver and has the ability to induce apoptosis in hepatocytes (Hepatocellular carcinoma cells) it is hypothesized that TTV is an opportunistic virus and in certain conditions causes liver damage. In this study the frequency of infection with TTV...

the purpose of this study was to analyze biotechnology experts’ attitude in university centers of tehran province towards use of transgenic plants. the design of the study was descriptive, and it was carried out through a survey method. the target population consisted of biotechnology experts in university centers of tehran province (n=75). though kerjcie and morgan sample size table and ratio ...

Armillaria genus represents one of the most common causes chronic root rot disease in woody plants. Prompt recognition diseased plants is crucial to control pathogen. However, current detection methods are limited at a field scale. Therefore, an alternative approach needed. In this study, we investigated potential hyperspectral techniques identify fungi-infected vs. healthy Vitis vinifera. We u...

Background and aim: From long time ago, traditional medicine was integrated with popular culture and various aspects of treatment have been allocated to it. At the present time, the use rate of this method depends on people’s belief and recognition. Experimental: The research was conducted in the region Mobarakeh, Iran, in order to identify the priorities for application of medicinal plants by...

The effects of different coating time of PANI/Silver onto polysulfone (PSf) membrane surface were investigated based on the morphology, contact angle, surface roughness and rejection towards BSA, pepsin and trypsin. The membrane was prepared by employing the pressure deposition method toward phase inversed membrane. Thus, PANI particles were forced to adhere on membrane surface by pressure driv...
