Abstract Introduction Chlorinated paraffins (CPs) are important additives in a variety of chemical processing. Based on the lengths carbon chains, CPs classified into short-chain (SCCPs, C10-13), medium-chain (MCCPs, C14-17) and long-chain (LCCPs, C18-30) with chlorine content ranging from 30%-70%. SCCPs were listed persistent organic pollutants (POPs) by Stockholm Convention due to its toxicit...

Inhibition evoked from primary afferents in the electrosensory lateral line lobe of the weakly electric fish (Apteronotus leptorhynchus). J. Neurophysiol. 80: 3173-3196, 1998. The responses of two types of projection neurons of the electrosensory lateral line lobe, basilar (BP) and nonbasilar (NBP) pyramidal cells, to stimulation of primary electrosensory afferents were determined in the weakly...

in the GenBank non-redundant DNA database was examined. Two additional cases of ISAba1 associated with distinct ampC alleles were found in accession numbers EU604835 8 and AY325306. 3 In both of them, the IS was again in the same orientation and separated from the ATG initiation codon of ampC by 9 bp. The number of single nucleotide differences between the various ampC alleles is shown in Table...

UNLABELLED Codon usage bias (CUB) is an omnipresent phenomenon, which occurs in nearly all organisms. Previous studies of codon bias in Plasmodium species were based on a limited dataset. This study uses whole genome datasets for comparative genome analysis of six Plasmodium species using CUB and other related methods for the first time. Codon usage bias, compositional variation in translated a...

We revisit the notions of interface and component algebra proposed by de Alfaro and Henzinger in [7] for component-based design and put forward elements of a corresponding interface theory for service-oriented design. We view services as a layer that can be added over a component infrastructure and propose a notion of service interface for a component algebra that is an asynchronous version of ...

The vitamin D-binding protein, also known as groupspecific component (Gc) or Gc-globulin, is a 51.2-kDa polymorphic protein of the a2-macroglobulin fraction of human plasma (1 ). In human population, three common alleles (Gc1f, Gc1s, and Gc2) and .120 rare variant alleles have been classified by isoelectric focusing (2 ). Gc1f and Gc1s contain sialic acid residues, whereas Gc2 does not (2 ). Gc...

Sir, Worldwide, resistance to carbapenems, imipenem and meropenem is widespread among Acinetobacter causing infections and most resistant isolates are also resistant to many other antibiotic classes. Several class D b-lactamases can hydrolyse carbapenems, conferring resistance. The blaOXA-23 gene was the first to be found and was originally identified in a conjugative plasmid from a clinical Ac...

Vitamin D status is universally assessed by measuring circulating total 25-hydroxyvitamin D [25(OH)D], the sum of 25(OH)D3 and 25(OH)D2. However, despite the widespread acceptance of this biomarker of vitamin D status, studies have suggested that measurement of 25(OH)D alone may not be sufficient to understand the relationship between vitamin D exposure and certain health outcomes. As a result,...
