Carbon nanotubes (CNTs) have been introduced recently as a novel carrier system for both small and large therapeutic molecules. CNTs can be functionalized (i.e., surface engineered) with certain functional groups in order to manipulate their physical or biological properties. In addition to the ability of CNTs to act as carriers for a wide range of therapeutic molecules, their large surface are...
The magnetic phase diagrams, and other physical characteristics, of the hole– doped La2−xSrxCuO4 and electron–doped Nd2−xCexCuO4 high–temperature superconductors are profoundly different. Given that it is envisaged that the simplest Hamiltonians describing these systems are the same, viz. the t − t − J model, this is surprising. Here we relate these physical differences to their ground states’ ...
The optimal method for early detection of breast cancer in premenopausal women is not known. To date, mammographic screening and physical exam are the best available approaches for early detection in the general population. However, these methods may not be sufficient in young women. Therefore, there is an urgent need for new approaches that can augment mammographic screening and physical exam,...

hepatitis c virus (hcv) infection causes chronic hepatitis, which frequently leads to hepatic fibrosis and hepatocellular carcinoma (hcc). alanine aminotransferase (alt) is a biomarker of hepatocyte injury and is associated with the progression of hepatic fibrosis. advanced hepatic fibrosis also predisposes hcv carriers to a risk of hcc. in contrast, some cases with persistent hcv infection hav...
Medical liability coverage has become increasingly expensive and scarce since 2001, especially for obstetrics and other high-risk specialties. Physicians, whose own fees are constrained, see this as a crisis needing tort reform to cap payouts. Plaintiffs' lawyers fight caps; they blame insurance trends and call for stronger regulation of insurers and physicians. Doctors' arguments are somewhat ...
ABSTRACT More than 500 diffuse interstellar bands (DIBs) have been observed in astronomical spectra, and their signatures correlations different environments studied over the past decades to reveal clues about nature of carriers. We compare equivalent widths DIBs, normalized amount reddening, EB-V, search for anticorrelated DIB pairs using a data sample containing 54 DIBs measured 25 sightlines...
BACKGROUND Women with highly penetrant BRCA mutations have a 55-60 % lifetime risk for breast cancer and a 16-59 % lifetime risk of developing ovarian cancer. However, penetrance differs interindividually, indicating that environmental and behavioral factors may modify this risk. It is well documented that the risk for sporadic breast cancer disease can be modified by changing lifestyle factors...
BACKGROUND Lifestyle factors such as diet and physical activity have been shown to modify the association between fat mass and obesity-associated (FTO) gene variants and metabolic traits in several populations; however, there are no gene-lifestyle interaction studies, to date, among Asian Indians living in India. In this study, we examined whether dietary factors and physical activity modified ...
