There has been minimal research into how to best obtain DNA from touch samples. Many forensic laboratories simply moisten a swab with water and use it for collecting cells/DNA from evidentiary samples. However, this and other methods have not been objectively studied in order to maximize DNA yields. In this study, fingerprints were collected using swabs moistened with water or laboratory or com...

introduction and aims: h. pylori has been implicated in peptic diseases, some with detrimental consequences such as ulcer or cancer. since considerable genetic heterogeneity has been observed within h. pylori population worldwide, it appears an ideal achievement to recruit pcr-based methods and design genetic markers which recognize isolates from normal and symptomatic individuals. in this stud...

Understanding recent biogeographic responses to climate change is fundamental for improving our predictions of likely future responses and guiding conservation planning at both local and global scales. Studies of observed biogeographic responses to 20th century climate change have principally examined effects related to ubiquitous increases in temperature - collectively termed a warming fingerp...

This paper describes an exploratory research project which creates a classifier to distinguish artifacts containing content specific to a known computer virus, given a training set of samples of variants of that virus and using local alignments between the artifacts as its information source. A bioinformatics tool, BLAST, finds the local alignments between a digital artifact and a repository of...

BACKGROUND Tuberculosis (TB) is an important public health problem in the Northwest Territories (NWT), particularly among Canadian Aboriginal people. OBJECTIVE To analyse the transmission patterns of tuberculosis among the population living in the NWT, a territorial jurisdiction located within Northern Canada. METHODS This population-based retrospective study examined the DNA fingerprints o...

This paper will discuss the major developments in the area of fingerprint identification that followed the publication of the National Research Council (NRC, of the US National Academies of Sciences) report in 2009 entitled: Strengthening Forensic Science in the United States: A Path Forward. The report portrayed an image of a field of expertise used for decades without the necessary scientific...
