The sensitivity and specificity of novel UL37 exon 3 (UL37x3) and US3 immediate-early (IE) gene PCR primers to detect human cytomegalovirus (HCMV) DNA in clinical specimens are comparable to those of HCMV DNA polymerase (UL54) primers. The use of these IE primers increases the diagnostic performance of HCMV PCR.
The chemical syntheses of RNA oligomers containing modifications on the 5'-carbon of the 5'-terminal nucleoside for crystallographic and mechanistic studies of the hairpin ribozyme are reported. Phosphoramidites 4 and 8 were prepared and used in solid phase syntheses of RNA oligomers containing the sequence 5'-N'UCCUCUCC, where N' indicates either 5'-chloro-5'-deoxyguanosine or 5'-amino-5'-deox...
L-5-hydroxytryptophan (5-HTP) is the immediate precursor of serotonin. It is readily synthesized into serotonin without biochemical feedback. This nutrient has a large and strong following who advocate exaggerated and inaccurate claims relating to its effectiveness in the treatment of depression and a number of other serotonin-related diseases. These assertions are not supported by the science....
In mammalian genomes a sixth base, 5-hydroxymethylcytosine ((hm)C), is generated by enzymatic oxidation of 5-methylcytosine ((m)C). This discovery has raised fundamental questions about the functional relevance of (hm)C in mammalian genomes. Due to their very similar chemical structure, discrimination of the rare (hm)C against the far more abundant (m)C is technically challenging and to date no...
An artificial phosphopeptide recognized the difference between methylated and hydroxymethylated cytosines in DNA. The Sp1 zinc finger peptide substituted by phosphotyrosine effectively discriminated between 5-methylcytosine, 5-hydroxymethylcytosine ((hm)C) and unmethylated cytosine. The DNA recognition properties of the peptide differ from those of other chemicals that detect (hm)C.
Introduction: Nowadays, spinal anesthesia is associated with few complications in many surgical practices especially the elective caesarean which is taken as a suitable replacement for general anesthesia. Different drugs are used for spinal anesthesia. This study aims to compare lidocaine 5% in combination with meperidine 5% plus lidocaine 5% for spinal anesthesia in non-emergency cesarean pati...
