background: the memory impairment, obtained from intracerebroventricular (i.c.v.) infusion of streptozotocin (stz) in rats through activation of oxidative stress, is accepted as sporadic alzheimer’s disease (ad) model in most experimental studies. dimethyl sulfoxide (dmso) as a solvent is widely used in animal studies to have antioxidant effects as well. however, no report is available about dm...

background: cryopreservation of mammalian ovaries has been reported with different levels of success. cryopreservation of ovarian tissue may be a potential alternative for treatment of infertility and many attempts have been done to improve the efficiency of ovarian cryopreservation. the objective of the present study was to compare the direct cover vitrification (dcv) with ethylene glycol (eg)...

Solar cells incorporating metal-halide perovskite (MHP) semiconductors are continuing to break efficiency records for solution-processed solar cell devices. Scaling MHP-based devices larger area prototypes requires the development and optimization of scalable process technology ink formulations that enable reproducible coating results. It is demonstrated power conversion (PCE) small-area methyl...

In order to realize the anhydrous dyeing of linen fabric with reactive dyes in supercritical CO2, a CO2 ionic liquid reverse micelle system was constructed, and process this studied. system, can be dyed without special pretreatment. The results show that depth significantly improved by increasing amount surfactant. With increase temperature, first increases then decreases. pressure displays lit...

The photoexcited dynamics of a laser dye, 4-(dicyanomethylene)-2-methyl-6-(4-dimethylaminostyryl)-4H-pyran (DCM), in an acetonitrile solution and dimethyl sulfoxide (DMSO) were studied by pump–probe spectroscopy with 6-fs ultraviolet laser. UV light excites the DCM solved any or DMSO into locally excited (LE) state (via S0→S2 excitation), then LE relaxes to charge transfer state. In previous st...

Twenty rhesus monkeys were used to evaluate the effects of dexamethasone and dimethyl sulfoxide (DMSO) following experimental occlusion of the middle cerebral artery (MCA) for 17 hours. Animals were initially treated after four hours while the MCA remained occluded and a series of tests was used to evaluate the neurological and cerebral status of each monkey for seven days. The results show tha...

In the centrosymmetric dimeric title complex, [Fe(2)(C(14)H(10)N(2)O(4))(2)Cl(2)(C(2)H(6)OS)(2)]·2C(2)H(6)OS, two {Fe(L)Cl(DMSO)} units (L is the tridentate ligand 4-nitro-2-{[2-(oxidometh-yl)phen-yl]imino-meth-yl}phenolate; DMSO is dimethyl sulfoxide) are bridged by two O atoms, with an Fe⋯Fe separation of 3.1838 (8) Å. The coordination polyhedron of the Fe(III) atoms can be described as disto...

The expression of transgenes in a host plant may be low for a number of reasons. Both low expression and poor specificity of amplification were encountered during analysis of the expression of the Arabidopsis cytokinin oxidase/dehydrogenase (AtCKX1) gene in transgenic Centaurium erythraea. The optimization of the PCR protocol involved a gradient of annealing temperatures, as well as the applica...

Myeloperoxidase (MPO) synthesis is known to be associated with the promyelocyte stage of myeloid differentiation. In particular the downregulation of MPO gene transcription is associated with myeloid cell maturation. We examined the changes in the deoxyribonuclease I hypersensitive sites within the 5' end of the MPO gene and its 5' flanking region during dimethyl sulfoxide (DMSO)-induced differ...

Umbilical cord blood transplantation using nonmyeloablative conditioning is currently considered by many as a valid potential alternative for any patient who requires an unrelated donor allograft and who is without a suitably matched and readily available volunteer. Dimethyl sulfoxide (DMSO) has been used for years as a cryoprotectant agent; it acts by penetrating the cell and binding water mol...
