We have examined mitochondrial DNA (mtDNA) restriction-site variation within and between populations of fall-adult field crickets across a narrow hybrid zone in Connecticut. Our analysis reveals two distinct mtDNA lineages, each consisting of a single common genotype together with one or more rare genotypes. Outside the hybrid zone, the association between mtDNA genotype and species designation...

Derma is progenitor cells sours, which are able to differentiate further in several mesodermal lineage and neural and endodermal lineage. Culture conditions, skin taking site and culture medium composition considerably contribute to it. Spheroid cultured mesenchymal dermal cells contribution to skin regeneration in granulating wound in rat model was estimated.

We walk on two legs, carry around enormous brains and have colonized every corner of the globe. Anthropologists and biologists have long sought to understand how our lineage came to differ so profoundly from the primate norm in these ways, and over the years all manner of hypotheses aimed at explaining each of these oddities have been put forth. But a growing body of evidence indicates that the...

We consider the view data lineage problem in a warehousing environment For a given data item in a materialized warehouse view we want to identify the set of source data items that produced the view item We formalize the problem and we present a lineage tracing algorithm for relational views with aggregation Based on our tracing algorithm we propose a number of schemes for storing auxiliary view...

GATA-3 expression is crucial for T cell development and peaks during commitment to the T cell lineage, midway through the CD4(-)CD8(-) (double-negative [DN]) stages 1-3. We used RNA interference and conditional deletion to reduce GATA-3 protein acutely at specific points during T cell differentiation in vitro. Even moderate GATA-3 reduction killed DN1 cells, delayed progression to the DN2 stage...

Regulation of irreversible cell lineage commitment depends on a delicate balance between positive and negative regulators, which comprise a sophisticated network of transcription factors. Receptor activator of NF-kappaB ligand (RANKL) stimulates the differentiation of bone-resorbing osteoclasts through the induction of nuclear factor of activated T cells c1 (NFATc1), the essential transcription...

The concept of ‘community’ has a deep genealogy, extending from the classical social science literature of the nineteenth century to its wide and confused employment in policy contexts and textual analyses discourses. This paper will focus on one aspect of community whose lineage extends theoretically from the communal concept of a ‘consciousness of kind’. In the desert community of Mt Liebig, ...

BACKGROUND In April 2009, an A(H1N1) influenza virus of swine lineage was detected in humans in the USA, and in just over a month has infected over 10,000 people in more than 40 countries. OBJECTIVES To determine the performance of the Binax Now, BD Directigen EZ, and the Quidel QuickVue influenza rapid point-of-care (POC) tests for the detection of the recently emerged swine lineage A(H1N1) ...

Most Plasmodium falciparum-detecting rapid diagnostic tests (RDTs) target histidine-rich protein 2 (PfHRP2). However, P. falciparum isolates with deletion of the pfhrp2 gene and its homolog gene, pfhrp3, have been detected. We carried out an extensive investigation on 365 P. falciparum dried blood samples collected from seven P. falciparum endemic sites in Colombia between 2003 and 2012 to gene...
