Abstract: Fig latex has been a typical component in the health -promoting Mediterranean diet for millennia. To study its potential constituents, two varieties differing in color of fruit [Bidhi Bither: (BB); Kahli Bither: (KB)] and their growth area were analyzed for their organic extracts against sixteen microbes. The capacity of extracts was evaluated based on the inhibition zone, using the disc-diffusion assay, minimal inhibition concentration (MIC) for bacteria and yeasts, the method of calculating the inhibition percent…

Abstract: A great deal of works has been carried out assessing dye-decolorization capabilities of fungi, but only few species were investigated. In this present study, ten fungal species were screened for laccase activity by indicator plate method, of which five species were found to be laccase-positive. Laccase activity varied during growth and maximal laccase activity was observed during the 9th day, except for Agaricus bisporus. Pleurotus ostreatus gave the highest laccase activities, showing average value around 570 U/L…

Abstract: Successful utilization of Pleurotus ostreatus (Jacq.) P. Kumm. (type NRRL-0366) mushroom as a type of edible locally isolated mushroom in Egypt at the Mushroom Research Center (Mubarak City for Scientific Research and Technology Applications), to produce extensive hydrolyzing cellulase complex enzymes. This hydrolysis was approached in submerged culture supplemented with avicel PH101 as a substrate for endo-,exoglucanase production. The avicel concentration 6% yielded the maximum enzyme activities (2.46, 1.80 U/ml)…

Abstract: Eukaryotic expression plasmid (PVAX 1/E0) of E0 gene was constructed from an isolated strain of bovine viral diarrhea virus (BVDV) from sika deer and transfected into the BHK-21 cells to detect E0 gene transcription expression level and protein expression level. It was found that E0 gene could express in BHK-21 cells by RT-PCR and ELESA results. The humoral and cellular immune response levels were detected in rabbits immunized with PAVX1/E0 and inactivated vaccine by ELESA technology, which reached the peak after 4…

Abstract: In human, certain serological and molecular trials estimated an association between psychiatric diseases, particularly schizophrenia, mood disorders and borna disease virus (BDV). The purpose of this study was to investigate whether BDV has association with etiopathogenesis of schizophrenia. A total of 207 patients who were diagnosed with residual schizophrenia and 51 patient control grop with 134 healthy control group were included in the study. RNA of borna disease virus (BDV p24 and p40) in the peripheral blood…

Abstract: Cryptococcosis is a life-threatening fungal disease that usually presents as an opportunist infection in immunocompromised hosts, and Cryptococcus neoformans is the major opportunistic pathogen of cryptococcosis. Rapid diagnosis of C. neoformans and other opportunistic Cryptococcus pathogens is required to meet the clinical need for immediate treatment. Historically, negative staining with India ink has been used to identify Cryptococcus. Another staining method utilizes Alcian blue, a dye that reacts selectively w…

Abstract: Stochastic evolutionary game dynamics in hierarchy are very popular in economics and in management sciences. This study extends the model of stochastic evolutionary game dynamics. This paper highlights hierarchy selection model and we show that the hierarchy selection games are more stable without structures in this paper. Furthermore, an example in industrial organization is given to rationally explain the theory in this work.[...]

Abstract: Three Pleurotus spp., Pleurotus florida, Pleurotus ostreatus and Pleurotus sajar-caju, were screened for cellulolytic enzyme production under submerged fermentation conditions. Of these, P. florida, was studied for optimizing medium composition, incubation period, initial pH and incubation temperature to maximize cellulolytic enzyme production. Malt extract at 0.5%, 12 day of incubation period and 1% CMC as carbon source supported maximum production of cellulases. The optimum temperature and pH for maximum producti…

Abstract: To investigate the intercellular adhesion molecule-1 (ICAM-1) expression in the liver and serum hepatitis B virus (HBV) DNA level in chronic hepatitis B (CHB) patients before and after interferon (IFN) treatment, a total of 51 CHB patients were recruited and treated with IFN- 1b for 6 months. The expressions of ICAM-1 and serum HBV DNA were determined at baseline and after 6-month treatment by using immunohistochemistry and real time fluorescence polymerase chain reaction (PCR). The expression of ICAM-1 in the pati…

Abstract: The phytochemical screening and comparative study of antimicrobial activity of Aloe vera extracts was carried out. The phytochemical screening revealed the following metabolites: saponins, alkaloids, glycosides, tannins, protein, and flavonoids. While cardiac glyocosides and steroids were absent. The antimicrobial activities of the gel in 10% DMSO, methanol and aqueous extracts of green rind and leaf pulp were carried against some pathogenic clinical isolates, namely, Bacillus subtilis, Staphylococcus aureus, Prote…

Abstract: Forty seven fungal strains were isolated from plant debris in the tropical regions of Mexico, where fifteen of them were identified to species and twenty two to genus level. All isolates were grown in fermented rice and their EtOAc extracts screened against ten targets, four bacteria (Bacillus subtilis, Erwinia carotovora, Staphylococcus aureus and Xanthomonas campestris), the yeast Candida albicans, three phytopathogenic fungi (Alternaria tagetica, Colletotrichum gloeosporioides and Fusarium oxysporum), the Oomyce…

Abstract: Humankind has always been engaged in a relentless quest for energy to drive daily activities. However, most of the existing conventional strategies of tapping the environment are expensive and polluting. A nascent microbial fuel cell technology, relying on the degradation of wastewater such as cheese whey with the subsequent release of electricity, is thus the focus for sustainable energy. It is therefore important to gain an in-depth knowledge of the biology in these devices and possible avenues of enhancing power…

Abstract: Citrus tristeza virus (CTV) is the most important viral disease of Citrus spp. and has a worldwide distribution. Results of ELISA and PCR showed that all Citrus varieties including Fortunella sp., Citrofortunella microcarpa and Citromelo in major citrus growing areas of Malaysia had a high infection rate with CTV. In most areas, pomelo however was free of infection, but in Cameron Highlands, we found some strains of CTV that were severe to Citromelo and pomelo. Phylogeny studies revealed that these strains were sim…

Abstract: Honey, a natural product of very high nutritive value is made when the nectar (floral) and sweet deposits from plants (non floral) are gathered, modified and stored in the honeycombs by honeybees of the genera Apis and Meliponini. Its composition and quality vary greatly with the botanical source of nectar as well as environmental and climatic conditions. Depending on its quality, honey can contribute to the health and nutritional status of humans. These beneficial actions have been ascribed to its antimicrobial, a…

Abstract: In this study, we incubated four strains of Shigella in seawater microcosms (at room temperature and at 4°C) for eight months and we studied the alteration of their morphologic and outer membranes proteins. The starved cells showed an evolution to the filterable minicells state capable to pass membrane pore size 0.45 µm. In addition, the atomic force micrographs showed a reduction of the cells size and an evolution to coccoid-shapes. Outer membrane proteins patterns of stressed bacteria did not changed too much and…
