objective(s):transporters have an important role in pharmacokinetics of drugs. inhibition or induction of drug transporters activity can affect drug absorption, safety, and efficacy. p-glycoprotein (p-gp) is the most important membrane transporter that is responsible for active efflux of drugs. it is important to understand which drugs are substrates, inhibitors, or inducers of p-gp to minimize...

We study the absorption probability of minimally-coupled massive scalars by extremal p-branes. In particular, we find that the massive scalar wave equation under the self-dual string background has the same form as the massless scalar wave equation under the dyonic string background. Thus it can be cast into the form of a modified Mathieu equation and solved exactly. Another example that we can...

We search for sources and sinks of solar p-mode waves by creating absorption maps from Dopplergrams taken by the Michelson Doppler Interferometer (MDI) instrument on board SOHO. Although the maps are noisy, we present evidence for sources and sinks, of duration 0.5 { 1 hour or less, based on an autocorrelation analysis of maps made from sequential intervals of data. Emission and absorption near...

Fragility fractures, those fractures which result from low level trauma, have a large and growing socio-economic cost in countries with aging populations. Bone-density-based assessment techniques are vital for identifying populations that are at higher risk of fracture, but do not have high sensitivity when it comes to identifying individuals who will go on to have their first fragility fractur...

The absorption spectrum of light is known to be a "molecular fingerprint" that enables analysis of the molecular type and its amount. It would be useful to measure the absorption spectrum in single cell in order to investigate the cellular status. However, cells are too thin for their absorption spectrum to be measured. In this study, we developed an optical-cavity-enhanced absorption spectrosc...
