INTRODUCTION In Nepal, a number of private sector medical schools have opened recently; although sufficient numbers of doctors are graduating there continues to be a doctor shortage in rural areas. This article analysed the rural doctor shortage in Nepal and reviewed the international literature for strategies that may be suitable for use in Nepal. METHODS Original research articles, reviews,...

The goal is to show that an edge-reinforced random walk on a graph of bounded degree, with reinforcement weight function W taken from a general class of reciprocally summable reinforcement weight functions, traverses a random attracting edge at all large times. The statement of the main theorem is very close to settling a conjecture of Sellke [Technical Report 94-26 (1994) Purdue Univ.]. An imp...

Odorant receptor genes are expressed not only in the nose but also in testes, where they have been hypothesized to play a role in sperm chemotaxis. New data demonstrate that human odorant receptor hOR 17-4 may play similar roles in both tissues, lending support to the idea that chemical attraction is important for reproduction.

Some ascidians accumulate vanadium in vanadocytes, which are vanadium-containing blood cells, at high levels and with high selectivity. However, the mechanism and physiological significance of vanadium accumulation remain unknown. In this study, we isolated novel proteins with a striking homology to glutathione transferases (GSTs), designated AsGST-I and AsGST-II, from the digestive system of t...
