Sila- and germafluorenes containing alkynyl(aryl) substituents at the 2,7- position are strongly emissive with high quantum yields in organic solvents. Provided they sufficiently soluble water, their hydrophobic structures have potential for many biological industrial applications detection characterization of lipophilic structures. To that end, emission behaviors previously synthesized bis[alk...

introduction:  the  advent  of  dual-modality  pet/ct  scanners  has  revolutionized  clinical  oncology  by  improving lesion localization and facilitating treatment planning for radiotherapy. in addition, the use of  ct images for ct-based attenuation correction (ctac) decreases the overall scanning time and creates  a noise-free  attenuation  map  (6map).  ctac  methods  include  scaling,  s...

Dye sensitization on semiconductor catalyst TiO2 was performed with four different metallophthalocyanine (MPc) derivates (M: Zn, Cu, Co, and Si) using a modified sol-gel method. MPc derivatives were loaded at 1% mass ratio aiming to increase its photocatalytic action shift the light absorption higher UV region (365 nm). Non-ionic surfactant Triton X-100 (TX-100) used obtain homogenous mesa pore...

Surfactants can be extremely toxic to aquatic species and are introduced to the environment in a variety of ways. It is thus important to understand how other environmental constituents, in this case humic acids (HAs), may alter the toxicity of anthropogenic surfactants. Hatching and mortality assays of Artemia Franciscana were performed for three different toxic surfactants: Triton X-100 (Tx-1...

Solvation dynamics in a neat ionic liquid, 1-pentyl-3-methyl-imidazolium tetra-flouroborate ([pmim][BF4]) and its microemulsion in Triton X-100 (TX-100)/benzene is studied using femtosecond up-conversion. In both the neat ionic liquid and the microemulsion, the solvation dynamics is found to depend on excitation wavelength (lambda(ex)). The lambda(ex) dependence is attributed to structural hete...

Proteomics is a powerful tool for analysing differences in gene expression between bacterial strains with alternate phenotypes. Staphylococcus aureus strains are grouped on the basis of their sensitivity to methicillin. Two-dimensional gel electrophoresis was combined with MS to compare the protein profiles of S. aureus strains COL (methicillin-resistant) and 8325 (methicillin-sensitive). Refer...

Analysis of human platelet membrane proteins by crossed immunoelectrophoresis (CIE) in the presence of Triton X-100 (TX-100) has previously shown that glycoproteins (GP) IIb and IIIa are located in a single immunoprecipitate, band 16.2 To investigate whether IIb and IIIa are associated in a complex, we have analyzed TX-100-solubilized 125I-labeled membrane proteins by density gradient ultracent...

The aim of this study was to provide a preliminary examination of a disorder-specific treatment program for children with generalised anxiety disorder (GAD) that employed strategies targeting underlying cognitive factors. Forty-two children with a primary diagnosis of GAD, aged between 7 and 12 years, were randomly assigned to either a treatment (TX) or waitlist (WLC) condition. Clinical diagno...

The effect of thyroxine (T4) on phosphorylation of non-histone proteins in rat liver nuclei was studied. Non-histone proteins obtained by extracting liver nuclei with 0.4 mol X l-1 KCl from normal (N), hypothyroid (Tx) and Tx rats treated with T4 (100 micrograms kg-1 B.W.), respectively, were incubated with 32P-ATP at 30 degrees C for 5 min followed by sodium dodecyl sulfate-gradient polyacryla...

Femtosecond fluorescence upconversion experiments were performed on the naturally occurring medicinal pigment, curcumin, in anionic, cationic, and neutral micelles. In our studies, the micelles are composed of sodium dodecyl sulfate (SDS), dodecyl trimethyl ammonium bromide (DTAB), and triton X-100 (TX-100). We demonstrate that the excited-state kinetics of curcumin in micelles have a fast (3-8...
