Recovery of adenosine triphosphate after myocardial ischemia is limited by the slow adenine nucleotide de novo synthesis and the availability of precursors of the nucleotide salvage pathways. We determined the adenine nucleotide de novo synthesis in the dog by infusion of [C]glycine and the acceleration of adenine nucleotide built up by intracoronary infusion of ribose together with [C]glycine ...
Nucleotide sequences of nine 5' upstream gene regions for human, chimpanzee, gorilla, and orangutan were determined. We estimated nucleotide differences (d) for each region between human and great apes. The overall d was 0.027 (ranged from 0.004 to 0.052). Rates of nucleotide substitution were estimated by using d and divergence times of human, chimpanzee, gorilla, and orangutan. The overall ra...
Uterine infection is one of the reproductive diseases that can have disturbing postpartum uterine health in cattle. Therefore, identification of resistant genotypes to uterine infection is important. Lactoferrin (LF) is one of the major antimicrobial compounds in the normal uterine discharges of cows. We hypothesized that allelic diversity in LF gene may contribute to susceptibility or resistan...
The regular echinoids were recorded from Chennai Coast,Tamilnadu, South India and the animals were belong to 4 families, 5 genera and 5 species. An identification key to generic level and synoptic description are provided. Temnopleurid sea urchin Salmaciella oligopora (Clark, 1916) was recorded for the first time in 20-30m depth between Chennai and Pondicherry Coasts, South East Coast of India....
28, 36, and 41 kDa, On the other hand, Kurosawa et al.4) found an alkaline RNase in addition to three acid nucleases in frcsh fruit bodies of L, edodes confirming the results of Endo et aLi) To establish more precise information on these enzymes, we tried to isolate and characterize each nuclease or RNase in L. edodes. First, we isolated an acid RNase, RNase Le2, and established the prirnary st...
Two molecular species of repressible extracellular phosphodiesterases showing cyclic 2',3'and cyclic 3',5'-nucleotide phosphodiesterase activities were detected in mycelial culture media of wild-type Neurospora crassa and purified. The two molecular species were found to be monomeric and polymeric forms of an enzyme constituted of identical subunits having molecular weights of 50,000. This enzy...
Sites of transcription of polyadenylated and nonpolyadenylated RNAs for 10 human chromosomes were mapped at 5-base pair resolution in eight cell lines. Unannotated, nonpolyadenylated transcripts comprise the major proportion of the transcriptional output of the human genome. Of all transcribed sequences, 19.4, 43.7, and 36.9% were observed to be polyadenylated, nonpolyadenylated, and bimorphic,...
PDEs belong to a large superfamily [11 different gene families (PDEs 1–11)] of structurally related, functionally distinct, and highly regulated enzymes (Francis et al., 2001). Most PDE families comprise more than one gene ( 20 PDE genes), which generate multiple protein products ( 50 PDE proteins) via alternative mRNA splicing or use of different promoters/transcription initiation sites. Most ...
