We have performed large-scale molecular dynamics simulations of coexisting solid and liquid phases using 4e(s/r) interactions for n59 and n512, and for Lennard-Jones systems, in order to calculate the equilibrium melting curve. The coexisting systems evolve rapidly toward the melting temperature. The P – T melting curves agree well with previous calculations, as do the other bulk phase properti...

BACKGROUND DNA melting analysis for genotyping and mutation scanning of PCR products by use of high-resolution instruments with special "saturation" dyes has recently been reported. The comparative performance of other instruments and dyes has not been evaluated. METHODS A 110-bp fragment of the beta-globin gene including the sickle cell anemia locus (A17T) was amplified by PCR in the presenc...

The ABO blood group is the most important blood group system in transfusion medicine. In addition to the normal levels of ABO antigen expression, Ael and Bel represent the two major blood types that have a weak expression of the A or B antigens on red blood cells. Due to the fact that typing of Ael and Bel by conventional serological methods is time consuming and sometimes gives false-positive ...

BACKGROUND Previous studies have shown an association between the TaqIB polymorphism of the cholesteryl ester transfer protein (CETP) gene with plasma CETP and HDL concentrations and the progression of coronary artery disease (CAD). The aim of the present study was to determine the performance of two new fluorescence-based detection systems in the analysis of the TaqIB genotype. METHODS CAD p...

The X-ray fluorescence spectrometry and the MA.BM.006 reference spectrophotometric methods were used to determine the content of SiO2 (%) in bauxites from different deposits. The treatment of samples prior to the analysis involved the following steps: annealing, melting using the borax method,  and the formation of beads. Certified reference bauxite samples were used for the cali...

In recent years, Fluorescent Melting Curve Analysis (FMCA) has become an almost ubiquitous feature of commercial quantitative PCR (qPCR) thermal cyclers. Here a micro-fluidic device is presented capable of performing FMCA within a microchannel. The device consists of modular thermally conductive blocks which can sandwich a microfluidic substrate. Opposing ends of the blocks are held at differin...

Major histocompatibility complex (MHC) represents an important genetic marker for manipulation to improve the health and productivity of cattle. It is closely associated with numerous disease susceptibilities and immune responses. Bovine MHC, also called bovine leukocyte antigen (BoLA), is considered as a suitable marker for genetic diversity studies. In cattle, most of the polymorphisms are lo...

Walter Kauzmann's classic 1948 review of liquid supercooling and glass formation drew attention to the temperatures at which (by extrapolation) enthalpies and entropies of liquid and crystal phases would appear to become equal. In the temperature-pressure (T, p) plane, the collection of such 'Kauzmann temperatures' generate characteristic curves. The present study examines the connection of tho...
