Human touch samples represent a significant portion of forensic DNA casework. Yet, the generally low abundance genetic material combined with predominantly extracellular nature in these makes DNA-based analysis exceptionally challenging. proteins present same offer an abundant and environmentally-robust alternative. Proteogenomic methods, using protein sequence variants arising from nonsynonymo...

A 2-kilobase fragment containing the penicillin-binding protein 2 gene (penA) was amplified by using the polymerase chain reaction with DNA prepared from 35 penicillin-resistant strains of Neisseria meningitidis isolated in England, Ireland, and Spain (MICs, 0.16 to 1.28 micrograms of benzylpenicillin per ml) and from 10 penicillin-susceptible strains (MICs, less than or equal to 0.04 microgram...

In this study, a total of 24 Listeria spp. strains were analyzed. Twenty-two isolates were obtained in San Luis (Argentina) from human, animal, and food samples. Two types of strains, Listeria monocytogenes CLIP 22762 and Listeria innocua CLIP 74915, were included as reference strains. All isolates were biochemically identified and characterized by serotyping, phage typing, and amplification of...

DNA fingerprinting has been hailed by law-enforcement officials as the 20th century’s most important breakthrough in forensic science. They are eager to use the new technology to identify and prosecute violent criminals as well as to exonerate innocent persons who are suspects in criminal cases. Although DNA finger-printing has not yet been adequately tested in the courts, the State Attorney Ge...

Fingerprint-which have been used for about 100 years are the oldest biometric signs of identity. Humans have used fingerprints for personal identification for centuries and the validity of fingerprint identification has been well established. In fact, fingerprint technology is so common in Human Identification that it has almost become the synonym of biometrics. Fingerprints are believed to be ...

The unusual proportion of serotype D strains of Cryptococcus neoformans infecting patients diagnosed with cryptococcosis in some parts of France prompted the analysis of DNA fingerprints obtained with 26 clinical and 29 environmental isolates from the same area. Our results suggest that pigeon droppings are a potential source of pathogenic strains of C. neoformans serotype D, as previously demo...

ABSTRACT Both typical late season stem infections and atypical early season rosette infections of canola, a relatively new crop in the southeastern United States, were caused by Sclerotinia sclerotiorum. The 51 DNA fingerprints (from 71 isolates) did not match any fingerprints from previous studies of canola or other crops. Single locus haplotypes from nuclear DNA sequences included 18 in the i...

Complex microbial communities exhibit a large diversity, hampering differentiation by DNA fingerprinting. Herein, differential display-denaturing gradient gel electrophoresis is proposed. By adding a nucleotide to the 3' ends of PCR primers, 16 primer pairs and fingerprints were generated per community. Complexity reduction in each partial fingerprint facilitates sample comparison.

coronary artery disease (cad) is the most important cause of mortality and morbidity in the world. the knowledge of major risk factos can be useful in prevention of cad. there is no known major risk factof in many patients with myocardial infarction (mi). the dermatoglyphic pattern in patients with myocardial infarction is an interesting matter and little information is available about this rel...
