This paper mainly reports an experimental investigation on the residual mechanical and fracture properties of polystyrene aggregate concrete (PAC) after exposure to high temperatures up to 800 degrees Celsius. The fracture properties namely, the critical stress intensity factor ( K I C S ), the critical crack tip opening displacement (CTODC) for the Two-Parameter Model, and the fracture energy ...

Two genes encoding transcriptional regulators involved in sulfur assimilation pathways in Burkholderia cenocepacia strain 715j have been identified and characterized functionally. Knockout mutations in each of the B. cenocepacia genes were constructed and introduced into the genome of 715j by allelic replacement. Studies on the utilization of various sulfur sources by 715j and the obtained muta...

Photodynamic therapy (PDT) using a dihematoporphyrin ether (DHE) sensitizes malignant cells to damage by 630-nm light. This study investigated in vitro PDT sensitivity of human lung cancer cells (A549) and those factors which influence cell survival as determined by the colony formation assay. After incubation for 2, 4, or 6 hr with [DHE] of 2.5, 25, or 50 micrograms/ml, A549 received red light...

Methods In this two-stage crossover trial, seven females (mean age 26±4 years) were randomlyassigned to a sequence of two treatments (Rescue remedy and placebo) with a onemonth wash-out period. The Rescue remedy consisted of four drops of five flower essences (cherry plum, clematis, impatiens, rock rose and Star of Bethlehem) dissolved in brandy and 250 ml of distilled water. The placebo consis...

There is epidemiological evidence for a protective property of oestrogen on vasculature which may be linked to an ability to relax vascular smooth muscle [I]. 170 oestradiol was shown to relax rabbit aorta and coronary arteries [2,3] and dilate rat tail artery [4]. The biochemical target for this action is unclear, although effects on calcium flux have been implicated. Activation of protein kin...

The objective of this Phase I study was to evaluate the safety, tolerance, and pharmacokinetics of BMY-28100 in 36 male subjects after the administration of single oral doses of 250, 500, and 1,000 mg. The subjects were divided into groups of 12 per dose group. All subjects completed the study, and BMY-28100 was well tolerated at all doses. The maximum concentration of the drug in plasma ranged...
