Human Leukocyte Antigen (HLA) loci widely known for their role in generation of immune responses are often considered to be effective in reconstructing human phylogenies due to high degree of polymorphism and rarity of recombination observed at HLA loci. In the present study, we have made an attempt to substantiate the phylogenetic potential of HLA class II loci by analyzing DRB1, DQA1 and DQB1...

Interest is arising in the possible use of higher plants as the source of naturally occurring antibiotic substances. The use of higher plants in the treatment of disease is as old as the art of healing itself. Isaiah of Biblical times suggested that a plaster of figs be placed on boils as a treatment of this form of infection. Hyssop and cedarwood were used in the cleansing of lepers. The Orien...

Although drinking alcohol is an established esophageal cancer risk factor, the mechanisms by which alcohol induces this high-mortality rate cancer are not clear. To help elucidate this problem and develop an implementable preventive strategy, this genetic epidemiological study focused on aldehyde dehydrogenase 2 (ALDH2), the key enzyme for elimination of acetaldehyde generated by alcohol consum...

Total and differential white cell counts were studied in 399 women living in the same community in Britain but drawn from four different ethnic groups. The groups were white (northern European), Indian, black (African and West Indian), and Oriental. The total white cell count and absolute neutrophil count were significantly lower in the black group than in each of the other groups. The absolute...

BACKGROUND Primary lymphoepithelial-like carcinoma of the parotid gland is a rare tumour with an increased incidence among Eskimos and Orientals. In these populations, it is usually associated with Epstein-Barr virus. In Western countries, salivary gland lymphoepithelial-like carcinomas are uncommon and only 14 cases have been described so far; among these, only five cases showed Epstein-Barr v...

Background: Cytochrome P450 2C19 (CYP2C19) is a polymorphically expressed enzyme that shows marked interindividual and interethnic variation. CYP2C19*2 and CYP2C19*3 are the most frequently identified defective alleles in Orientals and Caucasian poor metabolizers (PM). The aim of this study was to investigate the frequencies of CYP2C19*1, CYP2C19*2 and CYP2C19*3 alleles and CYP2C19 genotypes in...

Ancient trees are famous for their life spans of hundreds or even thousands years. These rare, a testament to history and important scientific research. Platycladus orientalis, with the longest span beautiful trunk, has become most widely planted tree species is believed be sacred in China. Extensive declines habitat area quality pose greatest threats loss genetic diversity ancient P. orientali...

Heritage trees are long-lived or notable with great historical significance, scientific value, commemorative importance. Many heritage have been preserved in Weifang City, Shandong Province, Northern China. In this paper, the origin, species diversity, age structure, health, surrounding habitats, distribution, genera floristic composition, and challenges of protecting were investigated using li...

In this study, soil obtained from a reclaimed coal gob pile was expected to be rapidly improved with the use of artificial vegetation restoration practices, such as forests, which increase taxonomic variety in microbial community and its functions. order successfully identify effect forest project on soil’s quality, field study conducted loess hilly area located Shanxi assess effects five commo...
