The fungal genus Stemphylium (Ascomycota) contains selfing species that evolved from outcrossing ancestors. To find out how selfing originated, we analyzed the Stemphylium MAT loci that regulate sexual reproduction in ascomycetes and compared MAT structures and phylogeny with a multigene Stemphylium species phylogeny. We found that some Stemphylium species' MAT loci contained a single gene, eit...

OBJECTIVE Determining Leptospira sp. antibody seroprevalence and prevalent serovars in human and canine populations from three municipalities in the Tolima Department of Colombia. MATERIALS AND METHODS This was a cross-sectional study (subjects being selected by convenience sampling in 62 districts). Samples were collected from 850 dogs and 850 people during June, July and August 2007; these ...

Spectral analysis of the cell free extracts of four mat samples colonizing a Great Artesian Bain (GAB) aquifer bore runoff channel suggested that Thermus was present in the 75 degrees C grey mat, Meiothermus was present in the 66 degrees C red mat, a mixed population of Meiothermus/Thermus and photosynthetic microbes were present in the 57 degrees C green mat and photosynthetic microbes were pr...

This paper describes an analytical study that was performed as part of the development of an externally deployable energy absorber (DEA) concept. The concept consists of a composite honeycomb structure that can be stowed until needed to provide energy attenuation during a crash event, much like an external airbag system. One goal of the DEA development project was to generate a robust and relia...

The anti-Tac mAb has been shown to bind to the p55 chain of the IL-2R, block IL-2 binding and inhibit T cell proliferation. A humanized form of anti-Tac (HAT) has been constructed that retains the binding properties of murine anti-Tac (MAT). These two mAb were evaluated in cynomolgus monkeys to compare relative immunogenicity and pharmacokinetic properties. Monkeys treated with HAT daily for 14...

The combined effects of matrine (Mat) and cisplatin on the survival and apoptosis of rhabdomyosarcoma (RMS) RD cells, as well as the possible mechanism of the synergistic effect of Mat and cisplatin were investigated in the present study. RMS RD cells were divided and treated as follows: control group, 5 mg/l cisplatin group, Mat groups (0.5, 1.0 and 1.5 g/l), and Mat (0.5, 1.0 and 1.5 g/l) com...

OBJECTIVES To perform a literature review and meta-analysis evaluating the effectiveness of medial and lateral meniscus allograft transplantation (MAT). METHODS The literature review and meta-analysis were conducted between August and October 2015 in the People's Hospital of China Three Gorges University, Yi Chang, China. A systematic search was performed in the Medline and EMBASE databases, ...

The common colonization factor of Escherichia coli, the Mat (also termed ECP) fimbria, functions to advance biofilm formation on inert surfaces as well as bacterial adherence to epithelial cells and subsequent colonization. We used global mini-Tn5 transposon mutagenesis to identify novel regulators of biofilm formation by the meningitic E. coli isolate IHE 3034. Of the 4,418 transformants, we f...

BACKGROUND Maternal uniparental disomy of chromosome 6 (upd(6)mat) is a rare finding and its clinical relevance is currently unclear. Based on clinical data from two new cases and patients from the literature, the pathogenetic significance of upd(6)mat is delineated. METHODS Own cases were molecularly characterized for isodisomic uniparental regions on chromosome 6. For further cases with upd...

To our knowledge, 22 cases of chromosome 14 maternal uniparental disomy (UPD(14)mat) have been reported so far. The majority of cases were ascertained because of an abnormal phenotype associated with a Robertsonian translocation involving chromosome 14. We report here on a child with UPD(14)mat detected prenatally and resulting from trisomy rescue in a maternal meiosis I non-disjunction trisomi...
