Let Un; r be a uniform oriented matroid having as bases, B, all r-subsets (resp. as circuits, C, all (r + 1)-subsets) of {1; : : : ; n}. We say that C1 ⊆ C is a covering, of Un; r , if for any base B∈B there is a circuit C ∈C1 such that B ⊂ C. Let G(C1) be the graph having as set of vertices the elements of C1 and where two vertices are joined if they have one base in common. We say that C1 ⊆ C...

C1 catecholamine neurons reside within the rostroventrolateral medulla (RVLM), an area that plays an integral role in blood pressure regulation through reticulospinal projections to sympathetic preganglionic neurons in the thoracic spinal cord. In a previous investigation we mapped the efferent projections of C1 neurons, documenting supraspinal projections to cell groups in the preautonomic net...

background: the protein of niemann-pick type c1 (npc1) gene promotes the egress of cholesterol from late endosomes and lysosomes to other cellular compartments and contributes to a process known as reverse cholesterol transport. this study aimed to examine whether promoter methylation of npc1 is associated with risk of cardiovascular disease (cvd). methods: fifty cvd patients and 50 healthy sub...

the methylotrophic thermo tolerant actinomycete strain 381, was isolated from a compost sample, assimilated methanol during growth. methanol dehydrogenase could not be detected in cell extracts using dye-linked assays in the absence of nad+. dichlorophenol-indophenol-linked methanol oxidation was detected in broken cell suspensions in the presence of nad+ and the absence of cyanide. taxonomic s...

The aim of this study was to explore the cytochrome P450 2E1 (CYP2E1) RsaI/PstI polymorphism and risk of esophageal cancer (EC) in mainland Chinese populations. A systematic search of PubMed, EMBASE, Web of Science, CBM, CNKI and VIP databases for publications on the CYP2E1 RsaI/PstI polymorphism and risk of EC was performed. and the genotype data were analyzed in a meta-analysis. Odds ratios (...

Let M be a point set, C1 and C2 mutually exclusive closed subsets of M, and K a connected subset of M such that (1) K contains no points of the set C1 + C2 and (2) both C1 and C2 contain limit points of K. Then K, together with its limit points in C1 + C2, will be caUed a set K(C1,C2)M. If M has the property that for every two of its mutually exclusive closed subsets Cl, C2 and every connected ...
