The silicate layers revealed a much higher orientation into the flow direction in the uniaxially stretched films compared to the biaxially drawn samples. In addition, the orientation of the 001 plane of nanoclays was significantly
greater in the PLA compared to the PP nanoclay composite films probably due to a better intercalation and stress transfer in the former. Morphological pictograms illustrating the effects of uniaxial and biaxial stretching on the clay orientation are proposed. (c) 2011 Wiley Periodicals, Inc. J Appl Polym Sci, 2011″
“Anthracnose is a common Camellia oleifera disease caused by Colletetrichum Selleckchem Quisinostat gloeosporioide. This study was to isolate antagonistic bacteria from Camellia oleifera tissues LY3023414 concentration to control the anthracnose. Antagonistic bacteria was screened from 175 endophytic bacteria with confront culture method. The results of the study showed that the antagonistic effect of YB128 strain was the best with 86.1% inhibitory rate. According to the results of the researching on morphology, cultural characteristics, physiological and biochemical propertices, 16S gene sequence and molecular phylogenetic tree, YB128 was identified
as Bacillus licheniformis.”
“Background: The aim of this study was to consider the impact that multi-clone, complex infections have on a parasite population structure in a low transmission setting. In general, complexity of infection (minimum number of clones within an infection) and the overall population level diversity is expected to be minimal in low transmission settings. Additionally, the parasite population structure is predicted to be clonal, rather than sexual due to infrequent parasite inoculation and lack of
recombination between genetically distinct clones. However, in this low transmission of the Peruvian Amazon, complex infections are becoming more frequent, in spite of decreasing infection prevalence. In this study, it was hypothesized that sexual recombination between distinct clonal lineages of Plasmodium Selleck Quizartinib falciparum parasites were altering the subpopulation structure and effectively maintaining the population-level diversity.
Methods: Fourteen microsatellite markers were chosen to describe the genetic diversity in 313 naturally occurring P. falciparum infections from Peruvian Amazon. The population and subpopulation structure was characterized by measuring: clusteredness, expected heterozygosity (He), allelic richness, private allelic richness, and linkage disequilibrium. Next, microsatellite haplotypes and alleles were correlated with P. falciparum merozoite surface protein 1 Block 2 (Pfmsp1-B2) to examine the presence of recombinant microsatellite haplotypes.
Results: The parasite population structure consists of six genetically diverse subpopulations of clones, called “”clusters”".
