BACKGROUND Herpes zoster (HZ), or shingles, results from reactivation of latent varicella zoster virus in the sensory ganglia of adults, and results in significant morbidity in the elderly, including the development of post-herpetic neuralgia (PHN). The lifetime risk of HZ is about 20-30% and the incidence increases with age. The protective effect of the HZ vaccine has been shown in a large cli...

In a recent issue of the Proceedings, Jennings & Smyth (1990) investigated a critical aspect of the Holocene coastal evolution of much of Britain; namely gravel (or shingle) sediment supply and beach morphodynamics through time. Their study area is the coastline of East Sussex, and it should be noted that it is only a component of the larger coastal unit (or 'master cell') between Selsey Bill a...

G alvanized by rising costs, increased calls for greater accountability, and an Institute of Medicine (Washington, D. C., United States) report suggesting that medical errors may kill nearly 100,000 Americans every year [1], United States health care experts have tried to boost the quality of patient care by focusing on the speed and precision of service delivery. Several insurance companies ha...

South-Marutea Atoll is located at the south-eastern end of Tuamotu Archipelago, French Polynesia, central South Pacific. Understanding modalities islet building from low-lying atolls over mid to late Holocene, in relation sea-level changes and cycles marine hazard events, a prerequisite for better anticipate future geomorphic which islets will likely be faced next decades under global climate w...

Interpreters are routinely required to develop a continuous model of the subsurface through the integration of available data. One of the issues commonly encountered is how best to “fill in” the region between data points, or describe the region at a scale less than the scale of the sampling. We take this opportunity, as part of the Near-Surface Geophysics issue, to describe research currently ...

A 1999 autopsy study of young adults in the US between the ages of 17 and 34 years of who died from accidents, suicides, and homicides confirmed that coronary artery disease (CAD) is ubiquitous in this age group. The disease process at this stage is too early to cause coronary events but heralds their onset in the decades to follow. These data are similar to those reported in an earlier postmor...

The electron microscope was used to study the structure and three dimensional relationships of the components of the body cortex in thin sections of Paramecium multimicronucleatum. Micrographs of sections show that the cortex is covered externally by two closely apposed membranes (together approximately 250 A thick) constituting the pellicle. Beneath the pellicle the surface of the animal is mo...
