Effectiveness of Methenamine for UTI Prevention in Older Adults.

Methenamine is a drug used for the prevention of lower urinary tract infections (UTIs). However, efficacy has not been established in older adults or patients with varying degrees of kidney function. To evaluate the effectiveness of methenamine for the prevention of UTI in adults 60 years and older.

Enhanced detection of nanostructures by scanning electron microscopy using insulating materials.

We report a simple method by which 1D conducting structures with sub-micron diameters can be detected in a scanning electron microscope at magnifications more than an order of magnitude less than would be expected for their size. This enhanced detection was possible under normal operating conditions using a standard secondary electron detector. The technique requires only that the 1D samples must be in good physical contact with an insulating material.

Synthesis of freestanding HfO2 nanostructures.

Two new methods for synthesizing nanostructured HfO2 have been developed. The first method entails exposing HfTe2 powders to air. This simple process resulted in the formation of nanometer scale crystallites of HfO2.

The economic impact of a college of pharmacy.

Objectives: To quantify the dollar value of economic returns to a community when a college of pharmacy attains its fourfold mission of research, service, patient care, and education.

Methods: United States Bureau of Economic Analyses (BEA) RIMS II input/output analysis and data from student and faculty surveys were used to quantify the economic impact of the University of Tennessee's College of Pharmacy (UTCOP).

Results: The UTCOP's revenue of $22.
