Differentiating sensitivity of post-stimulus undershoot under diffusion weighting: implication of vascular and neuronal hierarchy.
(PLoS One, 2008-08-13)
The widely used blood oxygenation level dependent (BOLD) signal during brain activation, as measured in typical fMRI methods, is composed of several distinct phases, the last of which, and perhaps the least understood, is ...
Polyclonal B cell differentiation and loss of gastrointestinal tract germinal centers in the earliest stages of HIV-1 infection.
(PLoS Med, 2009-07-07)
BACKGROUND: The antibody response to HIV-1 does not appear in the plasma until approximately 2-5 weeks after transmission, and neutralizing antibodies to autologous HIV-1 generally do not become detectable until 12 weeks ...
Metronomic chemotherapy with daily, oral etoposide plus bevacizumab for recurrent malignant glioma: a phase II study.
(Br J Cancer, 2009-12-15)
BACKGROUND: We evaluated bevacizumab with metronomic etoposide among recurrent malignant glioma patients in a phase 2, open-label trial. METHODS: A total of 59 patients, including 27 with glioblastoma (GBM) and 32 with grade ...
Neuropeptide Y gene polymorphisms confer risk of early-onset atherosclerosis.
(PLoS Genet, 2009-01)
Neuropeptide Y (NPY) is a strong candidate gene for coronary artery disease (CAD). We have previously identified genetic linkage to familial CAD in the genomic region of NPY. We performed follow-up genetic, biostatistical, ...
In vivo visualization of abdominal malignancies with acoustic radiation force elastography.
(Phys Med Biol, 2008-01-07)
The utility of acoustic radiation force impulse (ARFI) imaging for real-time visualization of abdominal malignancies was investigated. Nine patients presenting with suspicious masses in the liver (n = 7) or kidney (n = 2) ...
Characterising phase variations in MALDI-TOF data and correcting them by peak alignment.
(Cancer Inform, 2005)
The use of MALDI-TOF mass spectrometry as a means of analyzing the proteome has been evaluated extensively in recent years. One of the limitations of this technique that has impeded the development of robust data analysis ...
A Vital Role for Interleukin-21 in the Control of a Chronic Viral Infection
Do smokers respond to health shocks?
(Review of Economics and Statistics, 2001-11-01)
This paper reports the first effort to use data to evaluate how new information, acquired through exogenous health shocks, affects people's longevity expectations. We find that smokers react differently to health shocks ...
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: ...
Micro-CT imaging of breast tumors in rodents using a liposomal, nanoparticle contrast agent.
(Int J Nanomedicine, 2009)
A long circulating liposomal, nanoscale blood pool agent encapsulating traditional iodinated contrast agent (65 mg I/mL) was used for micro-computed tomography (CT) imaging of rats implanted with R3230AC mammary carcinoma. ...
