The genus Phaseolus (Fabaceae) consists of some 50 species, all of which are distributed in the Americas. Four of these contain cultigens. P. vulgaris (common bean), P. lunatus (lima bean), P. acutifolius (tepary bean), P. coccineus subsp. coccineus (runner bean); and P. coccineus subsp, polyanthus (no English vernacular name). Biochemical markers--phaseolin seed storage protein and isozymes--h...

Rhodobacter sphaeroides is the first reported multiple chromosomal bacteria, a rod-shaped, Gram-negative bacterium [1]. The researchers provide a complete physical map of the Rhodobacter sphaeroides genome by obtaining chromosomal DNA fragments through restriction digestion with endonuclease from the genomic DNA, which support in establishing the existence of more than one chromosome [1]. Chrom...

The Noir Marron communities are the direct descendants of African slaves brought to the Guianas during the four centuries (16th to 19th) of the Atlantic slave trade. Among them, three major ethnic groups have been studied: the Aluku, the Ndjuka and the Saramaka. Their history led them to share close relationships with Europeans and Amerindians, as largely documented in their cultural records. T...

this study assessed the chemical and microbial contents in the water of public swimming pools in akwa ibom state, nigeria. a total of 16 public pools were selected through probability sampling from the 32 pools that existed in the five urban areas of akwa ibom state. water samples were collected from the sampled pools and tested in the laboratory for chemical and microbial contents. results sho...

background: using public swimming pools during different seasons and poor health behavior could be responsible in transmis­sion of fungal disease through pool water and its environment. therefore, this research was conducted to investi­gate fungal agents of indoor public swimming pools of ahwaz, capital city of khouzestan province, south-west of iran. methods : ten indoor swimming pools of ahwa...

BACKGROUND Genotyping error can increase both type I and II errors. In order to elucidate potential genotyping errors, data quality control often includes testing genotype data for deviations from Hardy-Weinberg Equilibrium (HWE). METHODS The Hardy-Weinberg Disequilibrium (HWD) coefficient and the ability to reject the null hypothesis of HWE were calculated analytically for genotype data from...

Hyperpolarization-activated cyclic nucleotide-modulated (HCN) channels and cyclic nucleotide-gated (CNG) channels are activated by the direct binding of cyclic nucleotides. The intracellular COOH-terminal regions exhibit high sequence similarity in all HCN and CNG channels. This region contains the cyclic nucleotide-binding domain (CNBD) and the C-linker region, which connects the CNBD to the p...

Background: Anthropological studies based on highly polymorphic HLA genes pro-vide useful information for bone marrow donor registry, forensic medicine, disease as-sociation studies, as well as designing peptide vaccines against tumors, and infectious or autoimmune diseases. Objective: This study was designed to investigate the genetic relationship of Iranian Arabs and Jews using HLA-class II g...
