PURPOSE Melanoma is a solid tumor that is notoriously resistant to chemotherapy, and its incidence is rapidly increasing. Recently, several signaling pathways have been shown to contribute to melanoma tumorigenesis, including constitutive activation of mitogen-activated protein kinase, Akt, and Stat-3. The activation of multiple pathways may account in part for the difficulty in treatment of me...

Tubuloreticular inclusions (TRIs) are subcellular structures located within the cisternae of endoplasmic reticulum. Formation of TRIs has been linked to the exposure of excess interferon (IFN), either from endogenous or exogenous sources. In renal disease, TRIs have been most commonly associated with systemic lupus erythematosus (SLE), and human immunodeficiency virus-associated nephropathy (HI...

This study aimed to analyze the effect of Alpinia purpurata K. Schum rhizome extract (APRE) supplementation into tris-egg yolk extender on sperm quality Bali bull after freezing. used experimental method with a completely randomized design (CRD), consisting five treatments, denoted as P0 (semen diluted using 100% Tris-Egg Yolk (TEY)), P1 98% TEY and 2% APRE), P2 96% + 4% P3 94% 6% P4 92% 8% APR...

The influence of fluorinated substituents on the luminescent properties rhenium-oxo, osmium-nitrido, and gold triarylcorroles was studied via a comparison four ligands: triphenylcorrole (TPC), tris(p-trifluoromethylphenyl)corrole (TpCF3PC), tris{3,5-bis(trifluoromethyl)phenyl}corrole (T3,5-CF3PC), tris(pentafluorophenyl)corrole (TPFPC). For each metal series examined, were found to enhance prop...

the synthesis of smcl3(thf)3 from smcl3.6h2o is described. the reaction of smcl3(thf)3 with nabh4 in dry thf gave white microcrystalline tris (tetrahydroborato) tris (tetrahydrofuran) samarium (iii), sm(bh4)3(thf)3. the vibrational and magnetic properties of sm(bh4)3(thf)3 have been studied.

A number of new charge-neutral zwitterionic tris(methimazolyl)borate ligands have been synthesized, either by substitution of the dimethylamine group in the adduct (dimethylamine)tris(methimazolyl)borane (1) or by insertion into its B-N(dimethylamine) bond by an unsaturated Lewis base. Two new anionic ligands, (thiocyanato)tris(methimazolyl)borate and (cyano)tris(methimazolyl)borate, have also ...

Solutions of tris(hydroxymethyl)aminomethane (Tris) have been shown to be a convenient primary standard for the Kjeldahl analysis. This compound is readily available in analytical reagent grade and has all the desirable properties of a primary standard. It is unnecessary to protect the Tris solution from C02, as any reaction between Tris and this gas cannot be detected by the titrimetric proced...

The aims were to evaluate the suitability of a non-commercial TRIS-lecithin (LC) extender and the effect of different concentrations of catalase (CAT) on motility, capacitation status (Chlortetracycline-assay) and zona pellucida (ZP) binding capacity of canine spermatozoa stored at +5 degrees C for 4 days. The sperm-rich fractions of the ejaculates of four stud dogs were divided into four aliqu...

The orientation of facial (fac) tris-cyclometalated iridium complexes in doped films prepared by vacuum deposition is investigated altering the physical shape and electronic asymmetry molecular structure. Angle-dependent photoluminescence spectroscopy Fourier-plane imaging microscopy show that roughly spherical fac-tris(2-phenylpyridyl)iridium (Ir(ppy)3) isotropic, whereas are oblate spheroids,...
