We have studied the effects of lipoxygenase inhibition and metabolite addition of HL-60 cells induced to differentiate. When HL-60 are induced by dimethyl sulfoxide (DMSO) in the presence of an inhibitor of lipoxygenase, caffeic acid, there is a marked change from the expected phenotype of mature granulocytes to a population composed predominantly of mature monocytes. (DMSO alone: 54% granulocy...

A wide range of primary pharmacological actions of dimethyl sulfoxide (DMSO) has been documented in laboratory studies: membrane penetration, membrane transport, effects on connective tissue, anti-inflammation, nerve blockade (analgesia), bacteriostasis, diuresis, enhancement or reduction of the effectiveness of other drugs, cholinesterase inhibition, nonspecific enhancement of resistance to in...

In a previous study, we found that crocidolite (an asbestos fiber) had an inhibitory effect on the differentiation process of HL-60 cells induced by dimethyl sulfoxide (DMSO). Here we describe the cathepsin B-like enzyme HL-60 cells and the changes of its activity during cell differentiation with or without crocidolite treatment. The cathepsin B-like enzyme in HL-60 cell extracts had almost the...

Here, we present the first observation of a smectic B (Sm(B)) phase in a system of charged colloidal gibbsite platelets suspended in dimethyl sulfoxide (DMSO). The use of DMSO, a polar aprotic solvent, leads to a long range of the electrostatic Coulomb repulsion between platelets. We believe this to be responsible for the formation of the layered liquid crystalline phase consisting of hexagonal...

Activation of the c-ablprotooncogene occurs during the generation of both the Abelson murine leukemia virus and the bcrablfusion gene. To further dissect the biological properties of these proteins, we studied their effect on apoptosis. Using dimethyl sulfoxide (DMSO) to induce apoptosis in the murine myeloid progenitor cell line 32Dc13, we examined the effect of expression of both v-ab1 and bc...

Dimethyl sulfoxide (DMSO) has been shown to induce the differentiation of primary hepatocytes in vitro. When actively dividing poorly differentiated human hepatoma-derived (Huh7) cells were cultured in the presence of 1% DMSO, cells became cytologically differentiated and transitioned into a nondividing state, characterized by the induction of hepatocyte-specific genes. Moreover, these cells we...

Decreasing amount chemically reacted solution Non-aqueous amine systems have been suggested as energy-efficient alternatives to conventional aqueous post-combustion carbon capture, low regeneration temperatures can be achieved. solubility non-...

The title compound, [CoH(C(18)H(15)P)(2)(C(2)H(6)OS)(2)], was synthesized by the reaction of chloridotris(triphenyl-phosphane)cobalt(I), [ClCo(PPh(3))(3)], in the presence of one equivalent potassium hydridotris(pyrazol-yl)borate in dimethyl sulfoxide. The structure displays a distorted trigonal-pyramidally coordinated cobalt(I) atom, with two phosphane ligands and one DMSO ligand in the equato...

We proposed and demonstrated a “refreshable microfluidic channel.” This channel was constructed between two stacked glass slides with a 100 m thick spacer. Each surface of the slides was frosted by being ground with an abrasive and made hydrophobic due to the treatment with 1,1,1,3,3,3-hexamethyldisilazane. A line was drawn on the surface using dimethyl sulfoxide (DMSO) as the ink. Because this...

A direct injection gas chromatography method was developed for the determination of triethylamine and dimethyl sulfoxide (DMSO) in a drug substance (ML-189). Matrix effects were found to result in the overestimation of DMSO when methanol was used as diluent. Multiple approaches to eliminate matrix effects were unsuccessful; these included changes in sample size, split ratio, injector temperatur...
