Elevated postprandial glycaemia has been linked to CVD in a number of different epidemiological studies involving predominantly non-diabetic volunteers. The MiniMed continuous glucose monitor, which measures blood glucose every 5 min, over a 24 h period, was used to investigate changes in blood glucose readings before and after instigating a diet with low glycaemic index (GI) for 1 week in free...

introduction: the purpose of this study was to evaluate the morphologic surface of gutta­percha cones after cutting with different methods. materials and methods: the apical 3 millimeters of forty standardized, gutta-percha cones size 40 were cut off using scissors or a scalpel against a glass slab. the samples were then examined under scanning electron microscopy (sem) for topographic deformit...

symptoms of the leaf scorch disease on the leaves of oleander infected by xylella fastidiosa appearing for the first time in lebanon were confirmed by elisa tests and anatomical observations of sections of petioles by a scanning electron microscope. xylella fastidiosa was detected in the xylem forming bacterial aggregates in the lumen of tracheary elements. the bacterium colonizes and invades t...

INTRODUCTION Investigations of patterns of sexual arousal to certain groups of sexually explicit media (SEM) in the general population in non-laboratory settings are rare. Such knowledge could be important to understand more about the relative specificity of sexual arousal in different SEM users. AIMS (i) To investigate whether sexual arousal to non-mainstream vs mainstream SEM contents could...

In disciplines other than IS, the use of covariance-based structural equation modelling (SEM) is the mainstream method for SEM analysis, and for confirmatory factor analysis (CFA). Yet a body of IS literature has developed arguing that PLS regression is a superior tool for these analyses, and for establishing reliability and validity. Despite these claims, the views underlying this PLS literatu...

Nanomanipulators, whilst commonly used to lift out TEM samples prepared in the FIB, have a number of other potential applications and can aid in the chemical and crystallographic analysis of samples. Here, we discuss some of these alternative uses of nanomanipulators and show how they enable the EDS and EBSD analysis of thin samples in the FIB-SEM as well as serve as electrical probes and enabl...

Infections of F plasmid-containing strains of Escherichia coli by bacteriophage T7 result in membrane damage that allows nucleotides to exude from the infected cell into the culture medium. Only pifA of the F pif operon is necessary for "leakiness" of the T7-infected cell. Expression of either T7 gene 1.2 or gene 10 is sufficient to cause leakiness, since infections by phage containing null mut...

Colorectal cancer is the fourth commonest malignancy and the second leading cause of cancer related deaths in the United States. In the year 2001, there were an estimated total of 135.400 new cases of colorectal cancer. In terms of cancer deaths, this disease was estimated to account for 56,700 deaths in the United States. The lifetime risk of developing colorectal cancer for the American popul...
