Relationship of opioid use and dosage levels to fractures in older chronic pain patients.

Abstract: Background Opioids have been linked to increased risk of fractures, but little is known about how opioid dose affects fracture risk.

Overview of GridRPC: A Remote Procedure Call API for Grid Computing

Abstract: This paper discusses preliminary work on standardizing and implementing a remote procedure call (RPC) mechanism for grid computing. The GridRPC API is designed to address the lack of a standardized, portable, and simple programming interface. Our initial work on GridRPC shows that client access to existing grid computing systems such as NetSolve and Ninf can be unified via a common API, a task that has proven to be problematic in the past.

Optical coherence domain reflectometry guidewire

Abstract: A guidewire with optical sensing capabilities is based on a multiplexed optical coherence domain reflectometer (OCDR), which allows it to sense location, thickness, and structure of the arterial walls or other intra-cavity regions as it travels through the body during minimally invasive medical procedures. This information will be used both to direct the guidewire through the body by detecting vascular junctions and to evaluate the nearby tissue. The guidewire contains multiple optical fibers which couple light from the proximal to distal end. Light from the fibers at the distal end of the guidewire is directed onto interior cavity walls via small diameter optics such as gradient index lenses and mirrored corner cubes. Both forward viewing and side viewing fibers can be included. The light reflected or scattered from the cavity walls is then collected by the fibers, which are multiplexed at the proximal end to the sample arm of an optical low coherence reflectometer. The guidewire can also be used in nonmedical applications.

Durable carbon-coated li2s core-shell materials for high performance lithium/sulfur cells

Abstract: The disclosure provides methods for producing uniformly sized lithium sulfide materials which are coated with one or more durable and conductive carbon shells that impede the polysulfide shuttle. The disclosure further provides for the carbon coated lithium sulfide materials made therefrom, and the use of these materials in lithium sulfide batteries.

Herbal remedies of the Luo of Siaya District, Kenya: Establishing quantitative criteria for consensus

Abstract: Data based on independent interviews with 45 herbalists of the Luo of Siaya District, Kenya, comprised 1129 remedy reports and related to 330 species of plants. While 49% of the remedies were encountered only once we list here 66 remedies (49 taxa) that were confirmed through independent reports from three or more individuals. A log-linear model was applied to these data in order to establish criteria for evaluating the likely efficacy of specific remedies. A quantitative interaction effect was calculated for each remedy as a measure of its degree of confirmation. The validity of the values derived from the mathematical model is considered in relation to classical criteria for evaluating ethnomedicinal reports.
