Three subspecies of Artemisia tridentata occupy distinct habitats in the Great Basin of North America: ssp. wyomingensis in low, arid elevations; ssp. vaseyana in high, mesic elevations; and ssp. tridentata in intermediate zones. We evaluated differences in the drought experienced and drought tolerance among the subspecies. Drought tolerance was measured by two traits: the xylem pressure (Cx) c...

UNLABELLED The rodent arenavirus glycoprotein complex encodes a stable signal peptide (SSP) that is an essential structural component of mature virions. The SSP, GP1, and GP2 subunits of the trimeric glycoprotein complex noncovalently interact to stud the surface of virions and initiate arenavirus infectivity. Nascent glycoprotein production undergoes two proteolytic cleavage events: first with...

Actinomycetes are an uncommon agent of human infections and its pathogenic factors are not known. The present study reports a rare case isolation of an actinomycete from a woman pleural fluid; the strain was identified by 16S rRNA gene sequence analysis. This strain was tested to produce an extracellular protease that hydrolysis gelatin, casein and hemoglobin on agar mediums. The purification o...

In high-consequence systems, there is a high cost associated with failure. Thus, there should be strong evidence that the systems will not fail in the field. Such evidence cannot be obtained by traditional verification methods such as testing. Transformation-oriented programming (TOP) is a promising formal software development technique. In TOP, a source file that represents a correct formal sp...

This paper presents a kinetic model for the calculation of polymer chain sequence length distribution in a multi-component step-growth polymerization toward the synthesis of bisphenol A co-polycarbonate. The polymerization system consists of three different types of monomers with two kinds of reactive end groups (e.g. A = phenyl carbonate group, B = hydroxyl group), AR1A, BR2B, and BR3B. The ki...

Two types of molecular markers, random amplified polymorphic DNA (RAPD) and inter-simple sequence repeat (ISSR), were assayed to determine the genetic diversity of 46 barley accessions, including 27 landraces of H. vulgare ssp vulgare (HV), 6 accessions of H. vulgare ssp. spontaneum (HS) and 13 accessions of H. vulgare ssp. agriocrithon (HA), from west China. A high level of polymorphism was fo...

It is widely accepted that donor leukocytes survive within the recipient periphery after blood transfusion or solid organ transplantation. The significance of this microchimerism remains unclear, partially because of the insecurity of assays used to detect the donor-derived material. The techniques used to detect donor-derived DNA within recipient peripheral blood rely largely on major histocom...

To study the D-genome of the wild wheat relative Aegilops tauschii Cosson at the hexaploid level, we developed a synthetic doubled-haploid (DH) hexaploid wheat population, SynDH3. This population was derived from the spontaneous chromosome doubling of triploid F1 hybrid plants obtained from a cross between Triticum turgidum ssp. dicoccon PI377655 and A. tauschii ssp. strangulata AS66 × ssp. tau...

BACKGROUND Duffy (FY) blood group genotyping is important in transfusion medicine because Duffy alloantibodies are associated with delayed hemolytic transfusion reactions and hemolytic disease of the fetus and newborn. In this study, FY allele frequencies in Thai blood donors were determined by in-house PCR with sequence-specific primers (PCR-SSP), and the probability of obtaining compatible bl...
