A mesoscale model of DNA interaction with functionalized nanopore
(Copyright American Physical Society,, 2009-11-30)
Functionalized nanopores have been used recently for the detection of specific DNA. The
interactions between the DNA and the nanopore are not well understood due to the small size of
DNA/nanopore and dynamic translocation ...
Direct current electrical characterization of ds-DNA in nanogap junctions
(Copyright American Institute of Physics;, 2005-04-05)
Measurements of DNA conductivity, hybridization, and melting using electronic means can have wide applications in molecular electronics and biological sensors. We have fabricated nanogap break-junctions by electromigration ...
Effects of education, vaccination and treatment on HIV transmission in homosexuals with genetic heterogeneity
(2004)
Genetic studies report the existence of a mutant allele Δ32 of CC R5 chemokine receptor gene at high allele frequencies ( 10%) in Caucasian populations. The presence of the allele is believed to provide partial or full ...
A simple vaccination model with multiple endemic states
(Elsevier, 2000)
A simple two-dimensional SIS model with vaccination exhibits a backward bifurcation for some parameter values. A two-population version of the model leads to the consideration of vaccination policies in paired border towns. ...
Vector consumption and contact process saturation in sylvatic transmission of T. cruzi
(Taylor & Francis, 2006)
Recent research in the transmission of the protozoan parasite Trypanosoma cruzi,
some strains of which cause Chagas’ disease, suggests that consumption of vectors
by sylvatic hosts such as raccoons may play a role in ...
Am I too fat? Bulimia as an epidemic
(Elsevier, 2003)
For at least the past ten years, eating disorders have had a major impact in the
physical and mental health of women, particularly young women. Anorexia and bulimia
nervosa are closely linked eating disorders. Anorexia ...
Vaccination strategies and backward bifurcation in age-since-infection structured model
(Elsevier, 2002)
We consider models for a disease with acute and chronic infective stages, and variable infectivity
and recovery rates, within the context of a vaccination campaign. Models for SIRS and SIS
disease cycles exhibit backward ...
Strategies and policies for literacy
(UNESCO, 2004-05-31)
Executive Summary
Despite the existence of about one billion illiterates in the world, adult literacy programs
make up 1–5 percent of government or donor budgets, and they remain severely underfunded in
comparison to ...
The impact of vaccination and boinfection on HPV and cervical cancer
(American Institute of Mathematical Sciences, 2009-09)
Understanding the relationship between coinfection with multiple strains of human papillomavirus and cervical cancer may play a key role in vaccination strategies for the virus. In this article we formulate a model with ...
Criticisms of the Biopsychosocial Model in Spine Care: Creating and Then Attacking a Straw Person
(Lippincott Williams & Wilkins, Inc., 2008-12)
A previous article in Spine provided an erroneous and illogical critique of the biopsychosocial model. Evidence is used to refute concerns raised. We describe an evolving literature demonstrating the heuristic value of the ...
