Lablab (Lablab Purpureus) is a legume of high nutritional value and broad social acceptance ranging from human food to soil fertility improvement to foarge. Information on genetic worth and diversity of lablab genotypes in Kenya is scanty and this is a great impediment to the improvement of the crop hence its utilization. This research was conducted to determine genetic diversity in lablab germ...

Background Elymus sibiricus is an important native grass in Qinghai-Tibetan Plateau. Seed shattering is a serious problem for E. sibiricus, especially at harvest time. Cross breeding is an effective way to create new varieties with beneficial characteristic or improved traits, and to broaden genetic base. Results In this study, we created five hybrid populations by crossing seven E. sibiricus...

SEVERINGHAUS, JOHN W. Blood gas calculator. J. Appl. Physiol. 21(3): I 108-1 I 16. 1966.-A slide rule is described whose scales yield direct solutions of the following blood gas problems: r) the whole blood oxygen dissociation curve of man with variable temperature, pH, and base excess; 2) the effect of anaerobic temperature change on blood Pea , Pcoz , and pH; 3) the true oxygen consumption fr...

BACKGROUND The operational taxonomic unit (OTU) is widely used in microbial ecology. Reproducibility in microbial ecology research depends on the reliability of OTU-based 16S ribosomal subunit RNA (rRNA) analyses. RESULTS Here, we report that many hierarchical and greedy clustering methods produce unstable OTUs, with membership that depends on the number of sequences clustered. If OTUs are re...

Currently there are no evidence-based ecological measures for prevention of overgrowth and subsequent infection by fungi in the oral cavity. The aim of this study was to increase our knowledge on fungal-bacterial ecological interactions. Salivary Candida abundance of 82 Dutch adults aged 58-80 years was established relative to the bacterial load by quantitative PCR analysis of the Internal Tran...

BACKGROUND Circulus arteriosus cerebri is the main source of blood supply to the brain; it connects the left and right hemispheres with anterior and posterior parts. Located at the interpenducular fossa at the base of the brain the circle of Willis is the most important source of collateral circulation in the presence of the disease in the carotid or vertebral artery. AIM The purpose of the r...

Increasing economic interest in Jatropha curcas requires a major research focus on the genetic background and geographic origin of this non-edible biofuel crop. To determine the worldwide genetic structure of this species, amplified fragment length polymorphisms, inter simple sequence repeats, and novel single nucleotide polymorphisms (SNPs) were employed for a large collection of 907 J. curcas...

BACKGROUND The nasopharynx is a reservoir for pathogens associated with respiratory illnesses, such as asthma. Next-generation sequencing (NGS) has been used to characterize the nasopharyngeal microbiome during health and disease. Most studies so far have surveyed the nasopharynx as a whole; however, less is known about spatial variation (biogeography) in nasal microenvironments and how samplin...

Aflatoxin contamination of peanut, due to infection by Aspergillus flavus, is a major problem of rain-fed agriculture in India. In the present study, molecular characterisation of 187 Aspergillus flavus isolates, which were sampled from the peanut fields of Gujarat state in India, was performed using AFLP markers. On a pooled cluster analysis, the markers could successfully discriminate among t...

An investigation was carried out on a collection of 23 blackgram genotypes involving 16 released varieties, six pre release cultures and one wild species Vigna mungo var. silvestris to study the genetic diversity using twelve ISSR primers. The number of alleles produced by different ISSR primers ranged from eight to 17 with an average of 11.5 per primer and the level of polymorphism was found t...
