Specific IgE to proteins from Tribolium confusum (TC), a flour beetle, was detected in 9/125 sera of subjects exposed to rye and wheat flour. TC RAST was not inhibited by Dermatophagoides pteronyssinus, rye or wheat flour. Immunoblot experiments showed specific binding to three proteins from adult TC or pupae, not present in rye or wheat flour. These findings suggest that TC might act as an occ...

Selenium, an essential trace element possessing anticarcinogenic properties, can induce apoptosis in cancer cells. Our goal was to investigate the enhanced antitumor effects of photodynamic therapy (PDT) plus selenium in TC-1 tumor cells and implanted mice. Cell viability was evaluated at various time intervals after PDT treatment and/or selenium by methyl thiazolyl tetrazolium (MTT) assay. Whe...

El sangrado gastrointestinal es frecuente, resolviendose  en la mayoria de los casos forma espontanea. Sin embargo, este puede ser intermitente y en algunos masivo, con compromiso hemodinamico del paciente riesgo vital. En sentido muy importante realizar un diagnostico rapido certero sitio causa sangrado, para poder tratarlo adecuada. ocasiones dificil dada longitud tubo digestivo intermitencia...

BACKGROUND To investigative the association of triglycerides (TG) and total cholesterol (TC) concentrations with impaired fasting glucose/ impaired glucose tolerance (IFG/IGT) in Chinese adults. METHODS The population-based cross-sectional diabetes survey was conducted in 2006 and 2009 in Qingdao, separately. 4400 participants (1 793 men and 2607 women) were include in current analysis. IFG/I...

Two kinds of novel thymidine derivatives, N-thymidine-yl-N′-methyl-N′-{N′′-[2-sulfanyl-(ethylamino)acetyl]-2-aminoethylsulfanyl-1-hexanamide}-ethanediamine (TMHEA) and N-thymidine-yl-N′-methyl-N′-{N′′-[2-sulfanyl-(ethylamino)acetyl]-2-aminoethylsulfanyl-1-hexanamide}-hexanediamine (TMHHA) were prepared and successfully labeled with (99m)Tc in high labeling yields. The in vitro stability and in ...

Technetium-99m hexakis 2-methoxy-2-isobutyl isonitrile (Tc-MIBI) and thallium-201 extraction, washout, and retention were investigated and compared in 20 isolated, isovolumic, retrograde blood-perfused rabbit hearts at flow rates ranging from 0.5 to 3.5 ml/g wet wt min-1 in the absence of tracer recirculation. Mean Tc-MIBI peak instantaneous extraction was lower (0.55 +/- 0.10, p less than 0.00...

1. Materials and sample preparation High-quality single crystals of Sr2RuO4 used in this work were grown by the floatingzone technique and characterized in detail by standard techniques (S1). We found in the course of this work that crystals with an optimal superconducting transition temperature (Tc) around 1.5 K typically have more Ru inclusions than those with slightly lower Tc. However, thos...

A growing inefficacy of antimicrobial agents to treat infectious diseases has stimulated research on the development of antibiotic resistance in bacteria in the environment. Sustained exposure of soil microorganisms to tetracycline (TC) in flow-through columns (50mg/L influent) significantly decreased the effluent concentration of total heterotrophs and selected for TC-resistant (Tet(r)) soil b...
