The reactions of two diazabutadiene ligands, Ar-DAB [(ArN CH)2, Ar = 2,6-Pr2C6H3] and Bu-DAB [(BuN CH)2] with either GaI or an AlI3/Al mixture have afforded the paramagnetic compounds, [{IGa (Bu-DAB)}2], [I2Ga (Bu-DAB)] and [I2Al (Ar-DAB)] which have been characterised by X-ray crystallography and EPR spectroscopy. In addition, the diamagnetic, ionic complex, [I2Al (Ar-DAB)]I, has been prepared...

The cytochrome content of liver mitochondria and microsomes during the carcinogenesis of rat liver by both 3'-methyl-4-dimethylaminoazobenzene (3'-DAB) and 4'methyl-4-dimethylaminoazobenzene (4'-DAB), and of 3'DAB-induced hepatomas, was determined spectrophotometrically at room and liquid nitrogen temperatures and was compared with that of normal liver. The cyto chrome a + a3 content in the liv...

Digital Audio Broadcasting (DAB) is a digital method of delivering radio services from base station to the receiver. The main aim of this paper is to get better reliability of DAB reception in mobile (moving) environment. DAB is very forceful in mobile environment, but in some situations, reception fails in certain spots due to undesired audio interruptions. Antenna diversity systems are consid...

Dab (Limanda limanda) and haddock (Melanogrammus aeglefinus) were collected from coastal and offshore locations in the Baltic (dab only), North Sea (haddock from one location only) and Iceland. Blood was analysed for DNA strand breaks using the comet assay and liver samples for DNA adduct concentrations. DNA strand breaks were at background levels in dab from the two Iceland locations and from ...

Nowadays, most nucleic acid detections using fluorescent probes rely on quenching of fluorescence by energy transfer from one fluorophore to another or to a non-fluorescent molecule (quencher). The most widely used quencher in fluorescent probes is 4-((4-(dimethylamino)phenyl)azo)benzoic acid (DABCYL). We targeted a nucleoside-DABCYL analogue which could be incorporated anywhere in an oligonucl...

4-Dimethylaminoazobenzene (DAB, methyl yellow, or butter yellow), a human carcinogen, has been banned for use in foods since 1988. In 2014, DAB adulteration in Tofu occurred in Taiwan. We hypothesize that DAB can form [DAB•SBP]adduct adduct with soybean protein (SBP) which could damage Gastro-Duodenal-Hepatic axis. Sprague-Dawley rats gavage fed [DAB•SBP]adduct adduct revealed severely reduced ...

1,4-Dideoxy-1,4-imino-d-arabinitol (DAB) was identified previously as a potent inhibitor of both the phosphorylated and non-phosphorylated forms of glycogen phosphorylase (EC 2.4.1.1). In the present study, the effects of DAB were investigated in primary cultured rat hepatocytes. The transport of DAB into hepatocytes was dependent on time and DAB concentration. The rate of DAB transport was 192...

The ribonucleoprotein particles were isolated from livers of rats fed basal and 4-dimethylaminoazobenzene (DAB) diets, from DAB-induced primary tumors and from Novikoff hepatoma. The results showed that the protein and ribonueleic acid contents of the ribosomal fraction decreased equally in both basaland DAB-fed rats after seven weeks of feeding, and returned to normal levels after 23 weeks. Th...
