Abstract: Carbon nanotubes (CNTs) are very common in medical research and are being highly studied in the fields of biosensing methods for disease treatment and efficient drug delivery and health monitoring. The transportation of open-end Single wall carbon nanotube (SWCNT) through the cell membrane widely investigated because of many advantages. In our recent study, extensive quantum mechanical (QM) calculation of electronic structure of open-end of SWCNT and transportation of single wall carbon nanotube through the cell me…

Abstract: Avian influenza (AI) outbreaks due to H9N2 subtype of avian influenza virus (AIV) occurred in poultry industry in Iran, throughout the past decade and caused serious economic losses as a result of decreased egg production, increased mortality and the cost of vaccination in Iranian poultry industry. Our aim was to find the phylogenic and genetic relationships among avian influenza viruses recently isolated from poultry in Iran with other Asian H9N2 lineages (1998-2007). The complete nucleotide sequences of the neura…

Abstract: Flowering is a complex morphological happening that occurs in apical meristem of stem. This investigation was carried out to study the effects of two hormones including gibberellin (GA) and benzyl adenine (BA) on calla cut flower production. The rhizomes were dipped in GA solution with concentrations include (0, 100, 200 and 500 ppm). BA with concentrations (0, 100, 200 and 500 ppm) was sprayed on flowering stems until flowering time. The results showed that maximum flower yield was obtained in GA solution with con…

Abstract: Arbuscular mycorrhizal fungi, namely, Glomus mosseae and Glomus intraradices, and an endophyte, Piriformospora indica was used to assess the growth of two varieties (JS 335 and TAMS 98-21) of soybean (Glycine max L.) subjected to drought stress. Chlorophyll a fluorescence was measured by Handy PEA (plant efficiency analyzer) and analyzed by Biolyzer programme. The JIP-test (Chlorophyll a fluorescence rise at J I and P steps) was applied to evaluate in vivo vitality based on in vivo biospectroscopy, which supplied i…

Abstract: The aim of this work was evaluate action of oregano (Origanum vulgare) essential oil in treatment of experimental vaginal candidiasis. A batch of 50 Wistar rats was randomly allocated into four experimental groups corresponding to treatments: T1, 1.5% oil; T2, 3% oil; T3, Nystatin and T4, control treatment (emulsion). Oil concentrations were emulsified in agar suspension at 0.8%. Vulvovaginal candidiasis was established in ovariectomized and estrus-induced rats by intravaginal inoculation of Candida albicans (106 c…

Abstract: The present study focuses on the improvement of limitations of the bioluminescent ATP assay. An attempt was made to improve on the following: non-selective detection, limited cell population density quantification, and to distinguish between bioluminescent noises data and cell ATP, as a suitable technique for coliforms and ESCHERICHIA COLI detection, as well as other cell strains. Results were achieved by combining growth kinetics of the cell population exponential phase, in 2% brilliant green lactose bile broth wi…

Abstract: The benefits of probiotic microorganisms have been tested in several studies and they show many positive effects on human health like reduction of serum cholesterol, stimulation of immune system and prevention or treatment of human infections. This study has shown the activity of Lactobacillus brevis and Lactobacillus plantarum isolated from Iranian traditional cheese on cutaneous wound and describes the difference in healing activity between these two Lactobacilli. Some strains of Lactobacillus isolated from tradi…

Abstract: Q fever, caused by COXIELLA BURNETII, is a worldwide zoonosis that affects not wild animals but domestic animals throughout the world, except in New Zealand. Domestic ruminants are considered to be a major infection source of Q fever in humans. However, few studies on the prevalence of Q fever in humans or animals in Korea have been conducted. Thus, the aim of this study was to investigate the seroprevalence of Q fever in meat cattle and deer. Blood samples were collected from 1634 ruminants: 1000 cattle, 604 wapit…

Abstract: The environmental conditions on planet earth are extremely diverse, with enormous variations in pressure, pH, temperature and salt concentration. All these environments are inhabited by living organisms, particularly microorganisms which have adapted to the different extremes of environments. Among various extreme environments, low temperature is very common both in natural and man-made environments. Low temperature environment is a source for the isolation of cold adapted enzymes of commercial and industrial impor…

Abstract: Chitosan is a deacetylated derivative of chitin, consisting mainly of glucosamine units, commercially obtained from crustacean waste. This natural compound is biodegradable and nontoxic and has diverse applications in agriculture, among which highlights the control of fungal diseases in crops of agricultural interest. This review focuses on some basic studies about the mode of action and the effect of chitosan on different phytopathogens fungi. In general, it is known that molecules of this polymer can act on extra…

Abstract: The genus Bartonella is comprised of 20 species and subspecies, in which 10 species are responsible for human infections. The identification of the causative agent of cat-scratch disease, bacillary angiomatosis, urban trench fever, and Carrion's disease has raised the emerging medical importance of Bartonella spp. This article provides an overview of bartonellosis with emphasis on its prevalence in China.[...]

Abstract: A parasitic copepods study of Algerian teleost fish, report 25 copepod species belonging to eight families harvested from the gills of 14 fish species. The analysis of species richness according to some ecological, biological and taxonomical variables (Diet, Displacement, Way of life, Family) of the whole of hosts are reported in this study, the differences between mean specific richness (MSR) of all variables is statically significant according to Kruskal-Walis test using sigma stat software. Parasitic specificity…

Abstract: The potential of biofilm formation of 16 Paenibacillus strains and their inhibitory effect against bacterial wilt of tomato seedlings were examined in this study. The crystal violet assay indicated that all strains of Paenibacillus except strain MB02-1202 formed biofilm after 96 and 144 h of incubation while there was not significant difference in biofilm formation between strains of Paenibacillus polymyxa and strains of Paenibacillus macerans. However, the increase level of biofilm formation was associated with th…

Abstract: Environmental change and socio-economic pressure are expected to have significant impacts on Northern Alborz vegetation, particularly along ecotone such as the treeline. Remote sensing may be well suited to monitoring recent changes across the treeline because it captures integrated changes of all vegetation life forms over large spatial extents. This research examines treeline vegetation composition and change along the Nojmeh treeline using a high resolution, ETM+ 2000. In this paper we investigate the use of sat…

Abstract: The research was on the determination of the effect of light and salt concentrations on Aphanocapsa algal population. Microbiological standards were observed in the isolation of Aphanocapsa sp from water sample collected from Shell Petroleum flow station. The effect of 5,000, 3500 and 2,000 lux light intensities and 10 g/L through 50 g/L salt concentrations on the growth and proliferation of Aphanocapsa sp was determined by a spectrophotometer at 340 nm. At Day 9, the algal species gave the highest optical density…
