AFITbin: a metagenomic contig binning method using aggregate l-mer frequency based on initial and terminal nucleotides.

Background: Using next-generation sequencing technologies, scientists can sequence complex microbial communities directly from the environment. Significant insights into the structure, diversity, and ecology of microbial communities have resulted from the study of metagenomics. The assembly of reads into longer contigs, which are then binned into groups of contigs that correspond to different species in the metagenomic sample, is a crucial step in the analysis of metagenomics.

A dual functional turn off florescence sensor using metal-organic framework for sensitive detection of aluminum(III) in aqueous solution.

Aluminum, classified as one of the toxic heavy metals, has a recommended daily consumption limit of 3-10 mg, as specified by the World Health Organization (WHO). Herein, the selective and sensitive aluminum(III) fluorescence sensor based on TMU-16 metal-organic frameworks (MOFs) in aqueous medium, is reported. A sensing pathway was found via the cation exchange between aluminum(III) and zinc(II) ions, and caused selectivity and sensitivity detection of aluminum(III) with a 5-100 ppm linear range and 1.

The -514C/T Polymorphism of Hepatic Lipase Gene among Iranian Patients with Coronary Heart Disease.

Background: The T allele of the hepatic lipase (HL) C-514T polymorphism was previously found to be associated with lower plasma HL activity. Here, we examined the association between this polymorphism and plasma HDL-cholesterol concentrations in patients with coronary arteries stenosis.

Methods: We studied 342 subjects undergoing coronary angiography in two groups of non CAD (n=146) and CAD (n=196).
