The electrochemical oxidation behaviors of bilirubin (BR) at the bare glassy carbon electrode (GCE) were studied in dimethyl formamide (DMF) containing 1 vol.% of 1-butyl-3-methylimidazolium hexafluorophosphate ([bmim][PF6]) as the supporting electrolyte. Some electrochemical parameters of BR oxidation were investigated by cyclic voltammetry and chronocoulometry. The oxidation products were ide...

Most of the early identified brassinosteroid signaling and biosynthetic mutants are null mutants, exhibiting extremely dwarfed phenotypes and male sterility. These null mutants are usually unable to be directly transformed via a routinely used Agrobacterium-mediated gene transformation system and therefore are less useful for genetic characterization of the brassinosteroid (BR)-related pathways...

bacteriorhodopsin (br) is the light harvesting and photoactive proton pump found in the membrane of a salt marsh bacteria. this protein has significant potential to use in optical computing and memory devices due to unique intrinsic physical properties of photo and bioelectric. all these features make br one of the most promising protein candidates in protein memories. protein memory is a kind ...

A simultaneous injection effective mixing flow analysis (SIEMA) system was proposed for the spectrophotometric determination of palladium. The determination of palladium was based on its complexation reaction with 2-(5-bromo-2-pyridylazo)-5-[N-n-propyl-N-(3-sulfopropyl)amino]aniline (5-Br-PSAA) to form a blue complex, which has an absorption maximum at 612 nm. The analytical performances of the...

We report experimental and computational studies of the photolysis of atmospherically important 1,2-dibromoethanes (1,2-C(2)X(4)Br(2); X = H, F) in Ar matrixes at 5 K. Using the pulsed deposition method, we find that significant conformational relaxation occurs for 1,2-C(2)H(4)Br(2) (EDB; observed anti/gauche ratio =30:1) but not for 1,2-C(2)F(4)Br(2) (TFEDB; anti/gauche = 3:1), which is traced...

Dietary supplementation with beetroot juice (BR), containing approximately 5-8 mmol inorganic nitrate (NO3(-)), increases plasma nitrite concentration ([NO2(-)]), reduces blood pressure, and may positively influence the physiological responses to exercise. However, the dose-response relationship between the volume of BR ingested and the physiological effects invoked has not been investigated. I...

In order to study the interaction of genetic and hormonal factors during murine hepatocarcinogenesis, we compared the number of liver tumors induced by treatment of 12-day-old mice with N,N-diethylnitrosamine (DEN) (0.05 mumol/g body wt) in intact mice and animals gonadectomized at 8 weeks of age from the three inbred strains, C3H/HeJ (C3H), C57BL/6J (B6), and C57BR/cdJ (BR). At 50 weeks of age...

The most precise determinations of Vus comes from semileptonic kaon decays. The KLOE experiment at DAΦNE the Frascati φ factory , has measured all the experimental inputs to Vus for both neutral and charged kaons. Preliminary results for BR(K± → π0e±ν) and BR(K± → π0μ±ν), and for τ± are presented, together with measurements of the KLe3 and KLμ3 decay BR, the KSe3 decay BR and the KL lifetime τL...

UNLABELLED Bronchial responsiveness (BR) is an important risk factor for the development and outcome of asthma. This study assessed childhood risk factors for both the severity of BR in adulthood and either improvement or worsening of BR over time. Finally, we studied cross-sectional risk factors of BR in adulthood. Between 1966 and 1969, 119 allergic asthmatic children (5-14 yr of age) were st...

The purpose of this study was to assess the induced apoptosis of self-assembled iron oxide magnetic nanoparticles (MNPs) co-loaded with daunorubicin (DNR) and 5-bromotetrandrin (Br Tet) (DNR/Br Tet-MNPs), acting as a drug depot system for the sustained release of the loaded DNR and BrTet, in the drug resistant human leukemia K562/A02 cells and further to explore potential mechanisms. After bein...
