BACKGROUND This study aimed to compare the prevalence of Mycobacterium tuberculosis complex (MTBc) lineages between direct genotyping (on sputum) and indirect genotyping (on culture), to characterize potential culture bias against difficult growers. METHODOLOGY/PRINCIPAL FINDINGS Smear-positive sputa from consecutive new tuberculosis patients diagnosed in Cotonou, (Benin) were included, befor...

the effect of cocl2 as an ethylene synthesis inhibitor on changes of protein pattern was investigated in potato (solanum tuberosum l.) plants cultivar white desiree. in vitro grown plants were subjected to ms medium containing 0, 5, 10, 15, 20, 30, 40 and 60 mg/l cocl2 for 4 weeks. different concentrations of cocl2 showed significant effect on the total soluble proteins. among different concent...

The geographical environment, food culture, and dietary habits are substantially different between the southern and northern regions in China. We investigated the associations with dietary patterns and metabolic syndrome between Chinese adult from the southern and northern regions (North: 1249; South: 1849) using data from the Chinese Health and Nutrition 2009 survey. Respectively, four dietary...

In a joint research project – Human Factors in Air Navigation Services, HUFA – between the Swedish Civil Aviation Administration and Lund University the focus is on human and organizational factors and safety in air traffic control. The Swedish Air Navigation Services (ANS) are undergoing major organizational changes in order to adapt to changing demands on efficiency and technical development ...

introduction: the purpose of this study was to cultivate bone marrow cells from two different mouse strains (nmri and balb/c) and to examine them in terms of expression of ten surface antigens from primary culture to passage 3. material and methods: 6-8 weeks old either nmri or balb/c mice were sacrificed and their bone marrows were harvested and cultivated .two weeks after culture initiation, ...

The ability of a bacterial culture to manifest more than one set of culture characters is now recognized as a general phenomenon. Since the pioneer studies of Stryker,2" Baerthlein,3 Arkwright,2 and de Kruif6 two or more rather stable culture complexes, which, however, are capable of intertransition in a seemingly orderly manner under certain circumstances, have been described as occurring in m...

abstractone of the methods for communications with various people's culture and art is to understand their views and beliefs as well as possible. in many cases, such beliefs appear in the forms of motifs and pictures drawn on artworks and historical-cultural artifacts; therefore, recognition of these patterns is of great importance in this regard. the meander pattern is one of such motifs ...

the potential mycoherbicide alternaria alternata was isolated from one lesion on a leaf of amaranthus retroflexus which had been inoculated with conidia of the fungus. the isolate was cultured on v-8 agar medium. hyphal tip isolates (hti) were derived from young germ tubes of single spores and cultured on a semidefined culture medium with a c:n ratio of 15:1. amplified fragment length polymorph...

cellular and tissue activities highly depend on environmental ph. murine lung tissue, when cultured properly in-vitro, is a potent producer of hematopoietic growth factors. we have studied the effect of ph on the production of hematopoietic growth factors and protein synthesis by the murine lung in-vitro. various concentrations of nahc03 were used to adjust the ph of the culture medium under co...

Recent experimental and theoretical studies suggest that crystallization and glass-like solidification are useful analogies for understanding cell ordering in confluent biological tissues. It remains unexplored how cellular ordering contributes to pattern formation during morphogenesis. With a computational model we show that a system of elongated, cohering biological cells can get dynamically ...
