Cockayne syndrome (CS) is a human disease characterized by sensitivity to sunlight, severe neurological abnormalities and accelerated aging. CS has two complementation groups, CS-A and CS-B. The CSB gene encodes the CSB protein with 1493 amino acids. We

Every human cell has from a few dozen to several thousand mitochondria each of which contain mitochondrial DNA (mtDNA). The sequence of the entire human mtDNA (16,569 base pairs) was determined and published by Anderson et al. in 1981. A mtDNA standard
Tissue engineering is an emerging new area of biotechnology that will provide replacement tissues for patients, as well as complex, functional biological systems for research and testing in the pharmaceutical industry. However, a lack of a formal

8-oxoguanine (8-oxoG), ring-opened purines (formamidopyrimidines or Fapys), and other oxidized DNA base lesions generated by reactive oxygen species, are often mutagenic and toxic, and have been implicated in the etiology of many diseases including cancer

8,5'-Cyclopurine-2'-deoxynucleosides are among major lesions in DNA that are formed by attack of hydroxyl radical. These compounds represent a concomitant damage to both sugar and base moieties of the same nucleoside and thus can be considered tandem
Matrix-assisted laser desorption ionization time-of-flight mass spectrometry (MALDI-TOF MS)and ion pair-reverse phase high performance liquid chromatography (IP-RP HPLC) techniques were combined to determine the sequence identity of short single-stranded
The polysacharide gellan forms hydrogels if a divalent ion such as calcium is added at millimolar concentrations. The gel can be reversed to solution by adding EDTA, which makes it a promising candidate for preparative electrophoretic separation of

A DNA glycosylase specific for UV radiation-induced pyrimidine dimers has been identified from chlorella virus Paramecium bursaria chlorella virus-1. This enzyme (Chlorella virus Pyrimidine dimer glycosylase [cv-pdgl) exhibits a 41% amino acid identity

Endonuclease VIII from Escherichia coli is a DNA glycosylase/lyase that removes oxidatively damaged bases. EndoVIII is a functional homologue of endonuclease III, but a sequence homologue of formamidopyrimidine DNA glycosylase (Fpg). Using multiple

Polymer transport is central to many biological processes, including protein translocation, bacterial gene transduction and some modes of viral infection. To better understand the mechanisms of macromolecular transport, we are studying the ability of

Cockayne Syndrome (CS) is a human genetic disorder with two complementation groups, CS-A and CS-B. The CSB gene product is involved in transcription-coupled repair of DNA damage but may participate in other pathways of DNA metabolism. The present study

Y Chromosome short tandem repeat markers have a number of applications in human identity testing including typing the perpetrator of sexual assault cases without differential extraction and tracing paternal lineages for missing person investigations. In
Endonuclease VIII (Nei) is one of three enzymes in Escherichia coli that are involved in base-excision repair of oxidative damage to DNA. We investigated the substrate specificity and excision kinetics of this DNA glycosylase for bases in DNA that have

We have cloned a cya gene from a human pathogen Mycobacterium tuberculosis H37Rv by complementation of catabolic defect. (Accession No. AF017731, 1977). M. tuberculosis H37Rv genome sequence revealed five genes (Rv1264, Rv1318c, Rv1319c, Rv1320c, and
The Formamidopyrimidine N-DNA glycosylase (Fpg protein) of Escherichia coli is a DNA repair enzyme that is specific for the removal of purine-derived lesions from DNA damaged by free radicals and other oxidative processes. We investigated the effect of
8-Hydroxyadenine (8-OH-Ade) is one of the major lesions, which is formed in DNA by hydroxyl radical attack on the C-8 position of adenine followed by oxidation. We describe the measurement of the nucleoside form of this compound, 8-hydroxy-2'

This paper describes a microfluidic chip that enables the detection of viable Cryptosporidium parvum by detecting RNA amplified by nucleic-acid sequence-based amplification (NASBA). The mRNA serving as the template for NASBA is produced by viable C. parvum

Reliable amplification of short tandem repeat (STR) DNA markers with the polymerase chain reaction (PCR) is dependent on high quality PCR primers. The particular primer combinations and concentrations are especially important with multiplex amplification
Residual dipolar couplings can provide powerful restraints for determination and refinement of the solution structure of macromolecules. The application of these couplings in nucleic acid structure elucidation can have an especially dramatic impact since
Recent studies suggested that 8,5'-cyclo-2'-deoxyadenosine may play a role in diseases with defective nucleotide-excision repair. This compound is one of the major lesions formed in DNA by hydroxyl radical attack on sugar moiety of 2'-deoxyadenosine. It is
Mention has already been made, in Section 5.1. Of the use of DNA-based techniques for control of microbiological DNA. In parallel to the work of ATCC the USA National Institute of Standards and Technology (NIST) developed three Standard Reference Materials
