The regulatory functions of glycosaminoglycan hyaluronan (HA) are suggested to be dependent on its molecular weight (MW). Proinflammatory and stimulatory effects are proposed mainly for the low MW HA. However, the complex response of blood phagocytes to HA of different MW is unclear. Herein, the effects of highly purified HA of precisely defined MW (52, 250, and 970  kDa) on human blood phagocy...

Several studies suggest that mind wandering (MW) benefits creativity when the MW occurs in the incubation period of creative problem solving. The aim of present study was to examine the effects of MW that occurs in the course of creative idea generation. Participants received an Alternative Uses Task (AUT) and were asked to generate ideas for 20min. Their MW frequencies as time passed were meas...

Problem: Low MW peptides many of them N-substituted, have growth inhibitory effects. Are the peptide levels different in malignant cells from normal cells? Method: Deprimerones dissociated from DNA at pH 9.5 was measured in normal and malignant cells. The level of Low MW compounds was also compared to large MW compounds [ratios] after gel filtration. Result: Chalones and some other low MW compo...

In 1997 each LEP experiment collected approximately 55 pb −1 of data at a center-of-mass energy of 183 GeV. These data yield a sample of candidate e + e − → W + W − events from which the mass of the W boson, MW, is measured. The LEP combined result, including data taken at √ s = 161 and 172 GeV and assuming the Standard Model relation between the W decay width and mass, is MW = 80.35 ± 0.07(exp...

This study investigated mind-wandering (MW) in children during a laboratory task, and explored the influence of children's attitudes towards MW on the accuracy of their subjective reports. Children's MW experiences were probed during the adapted Sustained-Attention-to-Response-Task (SART), and their attitudes was measured by a questionnaire, according to which children were divided into positiv...

We have performed molecular dynamics (MD) simulations of zeolite-guest systems driven by microwaves (MW), to study how energy is distributed in these systems as a function of guest loading. Expanding on a previously published communication [Blanco, C.; Auerbach, S. M. J. Am. Chem. Soc. 2002, 124, 6250.], we have found that MW-driven MD with the Andersen thermostat gives robust steady states, wh...

It has recently been argued that researchers should distinguish between mind wandering (MW) that is engaged with and without intention. Supporting this argument, studies have found that intentional and unintentional MW have behavioral/neural differences, and that they are differentially associated with certain variables of theoretical interest. Although there have been considerable inroads made...

Antihemophilic factor (AHF, factor VIII) is a macromolecule that can be dissociated into two subcomponents. One, of high molecular weight (MW), forms precipitates with heterologous antiserum against AHF and supports ristocetin-induced aggregation of platelets. The other, of lower MW, has procoagulant activity. The plasma of patients with classic hemophilia contains a form of AHF with properties...

Poly(methyl methacrylate)s containing pendant octamethylcalix[4]pyrrole subunits were prepared and demonstrated to be capable of extracting tetrabutylammonium chloride and fluoride salts from aqueous media.

In this work, we describe laser modification of poly(methyl methacrylate) films doped with Fast Red ITR, followed by dopant exclusion from the bulk polymer. By this procedure, the polymer can be modified under extremely mild conditions. Creation of surface ordered structure was observed already after application of 15 pulses and 12 mJ cm(-2) fluence. Formation of grating begins in the hottest p...
