The genomic analysis of erythrocyte microRNA expression in sickle cell diseases.
(PLoS One, 2008-06-04)
BACKGROUND: Since mature erythrocytes are terminally differentiated cells without nuclei and organelles, it is commonly thought that they do not contain nucleic acids. In this study, we have re-examined this issue by analyzing ...
Yeast screens identify the RNA polymerase II CTD and SPT5 as relevant targets of BRCA1 interaction.
(PLoS One, 2008-01-16)
BRCA1 has been implicated in numerous DNA repair pathways that maintain genome integrity, however the function responsible for its tumor suppressor activity in breast cancer remains obscure. To identify the most highly conserved ...
Reported lifetime aberrant drug-taking behaviors are predictive of current substance use and mental health problems in primary care patients.
(Pain Med, 2008-11)
BACKGROUND: The aim of this report is to determine the frequency of aberrant drug behaviors and their relationship to substance abuse disorders in a large primary sample of patients receiving opioids for chronic pain. METHODS: ...
Optimized, unequal pulse spacing in multiple echo sequences improves refocusing in magnetic resonance.
(J Chem Phys, 2009-11-28)
A recent quantum computing paper (G. S. Uhrig, Phys. Rev. Lett. 98, 100504 (2007)) analytically derived optimal pulse spacings for a multiple spin echo sequence designed to remove decoherence in a two-level system coupled ...
Development of universal antidotes to control aptamer activity.
(Nat Med, 2009-10)
With an ever increasing number of people taking numerous medications, the need to safely administer drugs and limit unintended side effects has never been greater. Antidote control remains the most direct means to counteract ...
An immunoglobulin C kappa-reactive single chain antibody fusion protein induces tolerance through receptor editing in a normal polyclonal immune system.
(J Exp Med, 2005-03-07)
Understanding immune tolerance mechanisms is a major goal of immunology research, but mechanistic studies have generally required the use of mouse models carrying untargeted or targeted antigen receptor transgenes, which ...
HLA-B-associated transcript 3 (Bat3)/Scythe is essential for p300-mediated acetylation of p53.
(Genes Dev, 2007-04-01)
In response to DNA damage, p53 undergoes post-translational modifications (including acetylation) that are critical for its transcriptional activity. However, the mechanism by which p53 acetylation is regulated is still ...
Cdc25 and Wee1: Analogous opposites?
(Cell Division, 2007-05-04)
Movement through the cell cycle is controlled by the temporally and spatially ordered activation of cyclin-dependent kinases paired with their respective cyclin binding partners. Cell cycle events occur in a stepwise fashion ...
Substance abuse, treatment needs and access among female sex workers and non-sex workers in Pretoria, South Africa.
(Subst Abuse Treat Prev Policy, 2009-05-27)
BACKGROUND: This study examined cross-sectional data collected from substance-using female sex workers (FSW) and non-sex workers (non-SW) in Pretoria, South Africa, who entered a randomized controlled trial. METHODS: Women ...
