objective(s):multidrug resistance (mdr) of cancer cells is a major obstacle to successful chemotherapy. overexpression of breast cancer resistance protein (bcrp) is one of the major causes of mdr. in addition, it has been shown that pi3k/akt signaling pathway involves in drug resistance. therefore, we evaluated the effects of novel approaches including sirna directed against bcrp and targeted t...

The combination trimethoprim-sulfamethoxazole had no greater activity in a murine model of toxoplasmosis than did sulfamethoxazole alone.

Organic-inorganic hybrid sols (Ti-O-Si precursor) were first synthesized by the sol-gel method at low addition of water, and were then employed to prepare a highly refractive hybrid optical film. This film was obtained by blending the Ti-O-Si precursor with 2-phenylphenoxyethyl acrylate (OPPEA) to perform photo-polymerization by ultraviolet (UV) irradiation. Results show that the film transpare...

A smart and reversible chemo-mechanical switch was developed by synthesis of a thermally responsive block copolymer brush poly(N-isopropylacrylamide-co-hexafluoroisopropyl acrylate) (P(NIPAAm-co-HFIPA)) on a capillary plate. With the temperature changing around lower critical solution temperature (LCST), the designed chemo-mechanical switch exhibited excellent "ON-OFF" behavior for water transp...

We characterise the integrability of any co-CR quaternionic structure in terms of the curvature and a generalized torsion of the

Urinary tract infections caused by staphylococci are usually attributed to Staphylococcus epidermidis or S. saprophyticus. The case study reported here describes a persistent urinary tract infection caused by S. haemolyticus in a 38-year-old male whose infection was ultimately resolved through the use of the antibiotic trimethoprim-sulfamethoxazole.

The bond parameters and conformations of the N-H and C=O bonds of the SO(2)-NH-CO-C group in the title compound, C(12)H(17)NO(3)S, anti to each other, are similar to what has been observed in related structures. The benzene ring and the SO(2)-NH-CO-C group make a dihedral angle of 71.2 (1)°. Inter-molecular N-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers.
