The freezing behavior of dimethylsulfoxide (DMSO) and sorbitol solutions and periwinkle (Catharanthus roseus) cells treated with DMSO and sorbitol alone and in combination was examined by nuclear magnetic resonance and differential thermal analysis. Incorporation of DMSO or sorbitol into the liquid growth medium had a significant effect in the temperature range for initiation to completion of i...

The study aimed to investigate the effect of intrathecal injections of Tanshinone IIA on thermal hyperalgesia in a mouse model of bone cancer-pain. Spinal IL-1β, IL-6, TNF-α expression levels were analyzed. C3H/HeNCrlVr male mice were assigned to groups that either received dose-dependent injections of Tanshinone IIA, or the DMSO + Sham, Tanshinone IIA + Sham, DMSO + Tumor, and Control groups. ...

The solvent effects were studied in fluorescence resonance energy transfer (FRET) from a cationic polyfluorene copolymer (FHQ, FPQ) to a fluorescein (Fl)-labelled oligonucleotide (ssDNA-Fl). Upon addition of dimethyl sulfoxide (DMSO), the optical properties of polymers and the probe dye were substantially modified and the FRET-induced PL signal was enhanced 3.8-37 times, relative to that in pho...

The Ru(II) complex fac-[RuCl(dmso-S)(3)(dmso-O)(2)][PF(6)] (P2) was found to be an excellent precursor for the facile preparation in high yield of half sandwich-type compounds of the general formula fac-[RuCl(dmso-S)(3)(N)(2)][PF(6)] (e.g. (N)(2) = 1,2-diaminoethane (en, 4), trans-1,2-diaminocyclohexane (dach, 5), or 2 NH(3) (6)). Neutral half sandwich-type compounds of the general formula fac-...

The authors point out that dimethyl sulfoxide (DMSO) increases tissue perfusion and may effectively treat or prevent ischemia in flaps. They recommend application of topical DMSO every 4 to 6 hours, until blood flow improves, to areas that show signs of ischemia or less than adequate perfusion. Other potential cosmetic surgery uses of DMSO include areas of skin care, pain relief, and treatment ...

A phenol-catalyzed aerobic oxidative styryl ether formation method was developed with benzyl alcohol under basic DMSO. Styryl ether was obtained after 12 hours of heating at 60-80 °C where DMSO was involved in the reaction as the extra carbon source. Control experiments indicated that both phenol and DMSO are crucial for the success of the reaction. A variety of styryl ethers were prepared smoo...

Complexes [MII(2-pytz)Cl2] (M(II) = Pt, Pd; 2-pytz 2-(tetrazol-1-yl)pyridine) were synthesised via direct interaction of the corresponding metal chlorides (K2PtCl4 or PdCl2) with under ambient conditions. RuCl3 does not react reflux in protic media, while N, N-dimethylformamide presence LiCl, decomposition tetrazole cycle occurred leading to formation Ru(III)-coordinated N-dimethyl-N ′-(pyridin...

Effect of addition of a permeabilizing agent dimethyl sulfoxide (DMSO) and a solid adsorbent, XAD -7, on growth and coumarin production in hairy root cultures of C. intybus was studied. Continuous permeabilization of the hairy root cultures of C. intybus with DMSO has been shown to be an effective strategy for enhanced release of coumarins while preserving the root viability. DMSO at 0.2% (v/v)...

PURPOSE The universal organic solvent dimethyl sulfoxide (DMSO) can be used as a differentiation inducer of many cancer cells and has been widely used as a solvent in laboratories. However, its effects on breast cancer cells are not well understood. The aim of this study is to investigate the effect and associated mechanisms of DMSO on mouse breast cancer. METHODS We applied DMSO to observe t...
