Polysaccharides from many sources, catching more and more attention because of their multiple pharmacological activities [1-4], can be extracted by hot water, alkali, and enzyme and so on. In traditional viewpoint, polysaccharides are soluble in water for their hydroxyl and the solubility is the base of its bioactivities while insoluble polysaccharides have low or no bioactivities. The predomin...

INTRODUCTION This study compared simulated temperature distributions of intraluminal heating devices, concerning penetration and homogeneity. A hot water balloon, a 434-MHz monopole and a 915-MHz dipole antenna, both with incorporated cooling, and a 27-MHz applicator were investigated. METHODS The hot water balloon had an inlet temperature of 45 degrees C and a flow rate of 7.85 ml s(-1). The...

In the yeast, meiotic recombination is initiated by double-strand DNA breaks (DSBs) which occur at relatively high frequencies in some genomic regions (hotspots) and relatively low frequencies in others (coldspots). Although observations concerning individual hot/cold spots have given clues as to the mechanism of recombination initiation, the prediction of hot/cold spots from DNA sequence infor...

Abstract A non-isothermal vacuum assisted hot-forming process using tailored laminate temperature is introduced. By simulation and manufacturing experiments, improved quality achieved compared to the standard process. Furthermore, it also shown that time in clean room can be reduced one tenth of time. In this study 8.4 mm thick quasi-isotropic laminates from unidirectional prepreg were laid up ...

Homeostatic sensory systems detect small deviations in temperature, water balance, pH, and energy needs to regulate adaptive behavior and physiology. In C. elegans, a homeostatic preference for intermediate oxygen (O2) levels requires cGMP signaling through soluble guanylate cyclases (sGCs), proteins that bind gases through an associated heme group. Here we use behavioral analysis, functional i...

An increased number of intermittent renewables poses a threat to the system balance. As a result, new tools and concepts, like advanced demand-side management and smart grid technologies, are required for the demand to meet supply. There is a need for higher consumer awareness and automatic response to a shortage or surplus of electricity. The distributed water heater can be considered as one o...

Jakrem hot water spring is located in the West Khasi Hill District of the state of Meghalaya, and is one of the most popular hot springs of the state. There is a populist belief among the inhabitants and people that the hot spring water has got curative properties against various skin ailments. This is the first report on V3 hyper-variable region of 16S rDNA metagenome sequence employing Illumi...

The effect of hot water on aspen chips has been evaluated using time-domain low-field nuclear magnetic resonance (NMR) spectroscopy. At moisture contents above fiber saturation point, treated chips exhibit relaxation times of free water longer than for the control. This is consistent with the removal of hemicelluloses given the hydrophilicity of these polysaccharides. The rate of decrease in fr...

Wild, liquid state culture and solid state culture of Taiwanofungus camphoratus (Chang-chih) were sequentially extracted with cold water, methanol, and hot water to get cold water soluble, methanol soluble, and hot water soluble extracts respectively. The extracts from three Chang-chih were used to determine 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging, semicarbazide sensitive amine ...

Antimicrobial activities of the leaf extracts of Cymbopogon citatrus (lemongrass) and Vernonia amygdalina (bitter leaf) and the seed extracts of Garcinia kola (bitter kola) were carried out. G. kola had effect only on Staphylococcus aureus and Escherichia coli with no inhibition on Candida albicans. Ethanol, cold water and hot water extracts of Vernonia amygdalina and Cymbopogon citratus showed...
