Introduction: This report describes the synthesis of 2-Amino-2-deoxy(S-benzoylthioacetyl)-D-glucose (S-Bz-TA-DG), radiolabeled with [99mTc(CO)3(OH2)3]+ complex with a procedure including deprotection of the benzoyl group, characterization by HPLC using a C18 reverse phase column and preliminary biodistribution study in normal ...

there is a general rule in criminal law, principal of innocence. according to this rule, who asserts must prove. if she succeeds, ,this principal is replaced by pricipal of criminality, (as this pricipal is valid as far as the contrary is not proven). so, it is clear that the validity of this pricipal is based on the circumstances and reasonable inferences from these circumstances. if the situa...

Chemical-looped reverse water–gas shift reaction was investigated using transition metal/metal oxides as oxygen carriers. Iron is identified the only promising carrier that shows compelling CO 2 splitting reactivity. A chemically looped developed an iron-based carrier. Compared with conventional catalytic conversion processes, chemical looping method has advantage of high selectivity and cheap ...

With development of technology and science and continuous increase in productivity, product life cycles are shortened and customer demands are more personalized and diversified, which makes companies face with ever changing and unpredictable competitive environment. Therefore, rapid response to market competition has become one of the main focuses and the competitive advantages. Today, one of t...

We have analysed the reverse transcriptase (RT) activity of the human LINE retrotransposon and that of two retroviruses, using an in vivo assay within mammalian (murine and human) cells. The assay relies on transfection of the cells with expression vectors for the RT of the corresponding elements and PCR analysis of the DNA extracted 2-4 days post-transfection using primers bracketing the intro...

Proton-transfer kinetics in both ionic and neutral reverse micelles were studied by time-correlated single-photon counting investigations of the fluorescent photoacid 8-hydroxypyrene-1,3,6-trisulfonate (HPTS). Orientational dynamics of dissolved probe molecules in the water pools of the reverse micelles were also investigated by time-dependent fluorescence anisotropy measurements of MPTS, the m...

A triethylaluminium(TEAl)-modified Phillips ethylene polymerisation Cr/Ti/SiO2 catalyst has been developed with two distinct active regions positioned respectively in the inner core and outer shell of the catalyst particle. DRIFTS, EPR, UV-Vis-NIR DRS, STXM, SEM-EDX and GPC-IR studies revealed that the catalyst produces simultaneously two different polymers, i.e., low molecular weight linear-ch...

Integrated permeate channel (IPC) flat sheet membranes were examined for use as a reverse membrane bioreactor (rMBR) for lignocellulosic ethanol production. The fermenting organism, Saccharomyces cerevisiae (T0936), a genetically-modified strain with the ability to ferment xylose, was used inside the rMBR. The rMBR was evaluated for simultaneous glucose and xylose utilization as well as in situ...

To obtain a broad spectral response in the visible region, TiO2 film is co-sensitized with a porphyrin dye (FNE57 or FNE59) and an organic dye (FNE46). It is found that the stepwise co-sensitization in one single dye solution followed by in another single dye solution is better than the co-sensitization in a cocktail solution in terms of photovoltaic performance. The stepwise co-sensitization f...
