Recent advances in cyclonucleosides: C-cyclonucleosides and spore photoproducts in damaged DNA.
Cyclonucleosides which are fixed in a specific conformation around the glycosyl bond by a carbon and heteroatom chain constitute a unique category of nucleoside derivatives. Because they are structural analogs, cyclonucleosides and oligodeoxynucleotides containing them would be useful tools for investigating the biological functions and conformations of DNA, RNA as well as their steric interact...
متن کاملpostnatal studies of bats (pipistrellus kuhlii and miniopterus schreibersii) & histomorphology and histochemistry studies of organs and diseases of (neurergus microspilotus and n. kaiseri)
1. to determine whether difference in birth body mass influenced growth performance in pipistrellus kuhlii we studied a total of 12 captive-born neonates. bats were assigned to two body mass groups: light birth body mass (lbw: 0.89 ± 0.05, n=8) and heavy birth body mass (hbw: 1.35 ± 0.08, n=4). heavier body mass at birth was associated with rapid postnatal growth (body mass and forearm length) ...
The purine nucleotide cycle. Studies of ammonia production and interconversions of adenine and hypoxanthine nucleotides and nucleosides by rat brain in situ.
Electrical shock treatment produces a rapid loss of high energy phosphates in rat brain. The [ATP]/[ADP] ratio decreases to one-third of its control value within 10 s. The ammonia content increases 3-fold during the first minute after starting the stimulus. The total adenine nucleotide plus adenosine content of brain decreases an equivalent amount of hypoxanthine-containing compounds appears. A...
متن کاملVolumetric and Viscometric Studies of Nucleosides, Nucleotides and Furanose Sugar in Aqueous Medium from 288.15 to 298.15K
Density (r/g cm-3) and viscosity (h/10-2gcm-1s-1=1centipoise,CP) of guanosine monophosphate (GMP) and adenosine triphosphate (ATP) referred to as nucleotide, and 2-deoxy adenosine (DOA) and thymidine (TMD) as nucleoside along with their integral furanose sugar, 2-deoxy ribose (DOR) from 0.0004 to 0.0014mol kg<su...
متن کاملInteraction of low-energy electrons with the purine bases, nucleosides, and nucleotides of DNA.
The authors report results from computational studies of the interaction of low-energy electrons with the purine bases of DNA, adenine and guanine, as well as with the associated nucleosides, deoxyadenosine and deoxyguanosine, and the nucleotide deoxyadenosine monophosphate. Their calculations focus on the characterization of the pi* shape resonances associated with the bases and also provide g...
