The crystal structure of ( E )-doxepin hydrochloride has been solved and refined using synchrotron X-ray powder diffraction data, optimized density functional techniques. crystallizes in space group P 2 1 / a (#14) with = 13.78488(7), b 8.96141(7), c 14.30886(9) Å, ? 96.5409(5)°, V 1756.097(12) Å 3 , Z 4. There is strong discrete hydrogen bond between the protonated nitrogen atom chloride anion...

We herein report a universal calibration curve for the UV-visible spectrophotometric determination of concentration polymerizable dyes in solution. The method has been successfully applied to construct methylene blue water that is applicable over wide range and chloride concentrations, regardless both aggregate distribution temperature. In addition, it was found molar fractions each species sol...

Vasoconstriction via alpha(2)-receptors is known to be sensitive to acidic pH, but little is known about the pH sensitivity of P2X receptors. ATP is a cotransmitter released with norepinephrine from the sympathetic nerves and causes vasoconstriction via P2X purinergic receptors on vascular smooth muscle. We hypothesized that reductions in pH would attenuate P2X-mediated vasoconstriction in ilio...

Background: Dichloromethane (a chlorinated hydrocarbon) is normally used as a solvent. Dichloromethane poisoning has been reported from occupational exposure and the common routes of dichloromethane poisoning are ingestion and inhalation. Case presentation: We described a case of 51-year-old man who received subcutaneous injection of dichloromethane and presented with local wound necrosis at hi...

A novel method for preparing α-norbornene methylene polystyrene macromonomer (NBMPSt) is reported. NBMPSt macromonomer ( Mn = 1.60 × 10 and PDI = 1.26) had glass transition temperature (Tg) of 107 C for polystyrene segment. Since the homopolymerization of NBMPSt macromonomer with number average molecular weight ( Mn ) 1.60 ×10 could not be carried out by ring-opening metathesis polymerization (...

Three types of adhesives, urea-formaldehyde (UF) resin, phenol-formaldehyde (PF) resin, and polymeric methylene bis(phenyl isocyanate) (pMDI), were used for investigating the effect of pressing variables on volatile organic compound (VOC) emissions. The variables examined included press temperature and time, mat moisture content and resin content, and board density. The VOCs emitted during part...

*Correspondence: Ben Stuart , 122 Stocker Center, Athens, OH, 45701, USA e-mail: [email protected] Microalgae are a favorable feedstock for bioproducts and biofuels due to their high oil content, fast growth rates, and low resource demands. Solvent lipid extraction efficiency from microalgae is dependent on algal strain and the extraction solvent. Four non-polar extraction solvents were evaluated...

The plant Geum japonicum Thunberg (GjT) has been used as a diuretic in traditional medicine. Herein, we report that the GjT extract blocks both the spread of human umbilical vein endothelial cells (HUVECs) on matrigel and the migration of B16 cells. We used various assays to test for cell attachment, spreading, wound healing and angiogenesis. A reverse transcription-polymerase chain reaction (R...
