Has the polypill finally proven its worth?

Bioimpedance: Has Its Time Finally Come?

Bioimpedance, themeasurement of the frequency-dependent resistance to the flow of low energy electrical currents between two electrodes on or within the body, has been investigated for various medical applications for over 50 years. Applications in cardiology date back to at least 1966 and have included attempts to estimate stroke volume, cardiac output, cardiac contractility and lung fluid vol...

Neo-oogenesis: Has its existence been proven?

It was long believed that mammals are born with a fixed number of primordial follicles, each of which encloses an oocyte arrested at the diplotene step of meiotic prophase. Arising at or after birth, small numbers of primordial follicles become activated each day and enter a folliculogenic growth phase during which follicles either degenerate by atresia or complete maturation, resulting in ovul...

Modeling and Simulation in Mining - Its Time Has Finally Arrived

Finally neutrino has mass ?

The present status of the problem of neutrino mass, mixing and neutrino oscillations is briefly summarized. The evidence for oscillations of atmospheric neutrinos found recently in the Super-Kamiokande experiment is discussed together with the results of the solar neutrino experiments and the accelerator LSND experiment.

The Sodium “Leak” Has Finally Been Plugged

Most electrophysiologists generally do not speak highly of leak currents. In reality, these conductances represent a crucial functional mechanism by which neurons control resting membrane potentials. A new study in Cell by Lu et al. has surprisingly confirmed the identity of the long-sought voltage-insensitive sodium leak conductance to be encoded by the third branch of the voltage-gated sodium...
