Effect of Restricting Access to a Suicide Jumping Site

Australian & New Zealand Journal of Psychiatry, 2009
Objective: The road to a headland that had become a suicide jumping hotspot was temporarily closed because of construction work. This created an opportunity to assess whether loss of vehicular access would lead to a reduction in suicides and emergency police callouts for threatened suicide at the site.

Restriction sites as identification tags for lymphocyte cDNAs

ELECTROPHORESIS, 1997
AbstractA cDNA library was prepared from BW 5147 murine lymphoma cells in λ ecc III phage and randomly partitioned into 291 sectors, each with 800–1000 recombinant phage plaques. One sector was chosen for further characterization in terms of sensitivity to restriction endonuclease cutting. Aliquots of DNA preparations from this sector were treated with

Regular arrangement of restriction sites in drosophila DNA

Cell, 1975
When DNA of Drosophila melanogaster is digested to completion with Hemophilus aegyptius restriction endonuclease, the majority of the products are DNA segments whose lengths fits a random distribution with an average of 350 base pairs. However, some 10% of the DNA is recovered as various segments of discrete lengths, ranging from 30,000 to 365 base ...

Restriction site mapping for three or more enzymes

Bioinformatics, 1990
Restriction site mapping requires a generator to put forward possible maps and a constraint checker to reject false maps. Ideally these combine to give an algorithm which calculates a sound and complete solution set. Three algorithms for generation are presented and compared.

DNA fingerprinting by infrequent-restriction-site amplification

Journal of Clinical Microbiology, 1996
Identification of bacterial strains by DNA fingerprinting facilitates epidemiologic studies and improves disease control. For some species of organisms, no typing method is available; for others, typing methods are tedious. We developed a method of amplifying DNA sequences flanking infrequent restriction sites by PCR and used the method to produce ...

Differentiation of restriction sites in ribosomal DNA in the genusApodemus

Biochemical Genetics, 1990
Southern blot analysis of ribosomal DNA (rDNA) from seven species of Apodemus was carried out in order to examine the genetic relationships between the species. Analysis of heterogeneity in rDNA spacers in A. sylvaticus, A. flavicollis, A. semotus, A. agrarius, A. argenteus, A. speciosus, and A.

Phylogeny of tribe brassiceae (Brassicaceae) based on chloroplast restriction site polymorphisms and nuclear ribosomal internal transcribed spacer and chloroplast trnL intron sequences

, 2005
Using sequence data from the ITS region (internal transcribed spacers ITS-1 and ITS-2 of nuclear DNA and the 5.8 rRNA gene), chloroplast DNA (cpDNA) sequence data from the trnL intron, and cpDNA restriction site polymorphism data, we examined the ...

The site of the ion restricting membranes in the toad lens

Experimental Eye Research, 1969
Two experimental approaches have been used to determine whether the internal fibres of the amphibian lens have intact membranes. One approach involves an analysis of the potential transients obtained when potassium is substituted for sodium in the external medium and the other involves a correlation of lens electrical resistance with depth of ...

Determination of restriction sites and the nucleotide sequence surrounding the relaxation site of ColE1

Journal of Molecular Biology, 1978
Abstract The relaxation site of ColE1 has been located within the restriction fragment HpaII L, which is 148 base-pairs in length. Restriction mapping data indicate that the relaxation nick (the presumptive origin of transfer) of ColE1 is located at a distance of 250 to 300 nucleotides away from the replication origin, downstream in the direction of ...
