Dl-lsoleucine was complexed with Thioglycolic acid in the presence of Stannous ions to label with TC99m-Pertechnetate. Percentage labeling was determined by paper chromatography. Preparations of more than 95% labeled with Tc99m were injected to rabbits for imaging and tissue distribution studies. Tc99m.TGA.l LEU complex was investigated as a myocardial imaging agent with respect to its kinetics...

C-1 carriers are essential cofactors in all domains of life, and in Archaea, these can be derivatives of tetrahydromethanopterin (H(4)-MPT) or tetrahydrofolate (H(4)-folate). Their synthesis requires 6-hydroxymethyl-7,8-dihydropterin diphosphate (6-HMDP) as the precursor, but the nature of pathways that lead to its formation were unknown until the recent discovery of the GTP cyclohydrolase IB/M...

The problem of inferring the population structure, linkage disequilibrium pattern, and chromosomal recombination hotspots from genetic polymorphism data is essential for understanding the origin and characteristics of genome variations, with important applications to the genetic analysis of disease propensities and other complex traits. Statistical genetic methodologies developed so far mostly ...

Four patients with sonographic suggestion of hepatic hemangioma are studied with Tc99m-labeled RBC scan. The scan findings are compaired with other imaging modalities. Lesions as small as 36 mm could be detected by this method. Tc99m labeled RBC scan is a valuable tool to differentiate hepatic hemangioma from other space occupying lesion of the liver.

The hybrid mouse diversity panel (HMDP), a panel of 100 strains, has been employed in genome wide association studies (GWAS) to study complex traits in mice. Hearing is a complex trait and the CBA/CaJ mouse strain is a widely used model for age-related hearing loss (ARHI) and noise induced hearing loss (NIHL). The CBA/CaJ strain's youthful sensitivity to noise and limited age-related loss led u...

We present a new statistical framework called hidden Markov Dirichlet process (HMDP) to jointly model the genetic recombinations among possibly infinite number of founders and the coalescence-with-mutation events in the resulting genealogies. The HMDP posits that a haplotype of genetic markers is generated by a sequence of recombination events that select an ancestor for each locus from an unbo...

Previous studies had shown that the integration of genome wide expression profiles, in metabolic tissues, with genetic and phenotypic variance, provided valuable insight into the underlying molecular mechanisms. We used RNA-Seq to characterize hypothalamic transcriptome in 99 inbred strains of mice from the Hybrid Mouse Diversity Panel (HMDP), a reference resource population for cardiovascular ...

Technetium labelled Sucralphate has been used as an ulcer scanning agent in the gastrointestinal tract. The labelling described in the literature involves incubation of Tc99m-HSA (Human serum albumin) with Sucralphate. Due to difficulty in obtaining HSA we used bovine serum albumin (BSA) to tag radioactivity with Sucralphate. The radioactive yields (Tagged Sucraiphate and Tc99m-BSA) obtained af...

We describe a case of a 58-year-old male with longstanding hypertension and Type 2 diabetes mellitus who developed sudden onset renal impairment. The first clue to the possible presence of amyloidosis in this case was provided by the radionuclide renal cortical scan performed with trivalent dimercapto succinic acid (Tc99m-DMSA-3), which revealed intense tracer uptake in the spleen suggesting am...
