In 1999, Medicare implemented a resource-based relative value unit (RVU) system for physician practice expense payments, and increased the number of services for which practice expense payments differ by site. Using 1998-2004 data, we examined RVU growth and decomposed that growth into resource-based RVUs, site of service, and service quantity and mix. We found that the number services with sit...

objective(s):some pathologic situations such as diabetes and metabolic syndrome are associated with alternation in nitric oxide level. incidence of these condition increases with aging. on the other hand, insulin secretion is modulated by nitric oxide, and nitric oxide synthase (nos) activity is also altered in diabetes. in this study, modification in the enzyme activity associated with aging a...

Akin to other mineralized tissues, human cortical bone can resist deformation and fracture due to the nature of its hierarchical structure, which spans the molecular to macroscopic length scales. Deformation at the smallest scales, mainly through the composite action of the mineral and collagen, contributes to bone’s strength or intrinsic fracture resistance, while crack-tip shielding mechanism...

objective(s): in the current study, the effects of selected folk medicinal herbs were evaluated in d-galactose-induced aging in male mice.   materials and methods: male balb/c mice were randomly divided into 12 groups composing sham, control, and treated groups. aging was induced by administration of d-galactose (500 mg/kg/day for 6 weeks). a positive control group was assigned that received vi...

objective: antioxidants are essential for sperm motility. calligonum extract possesses the important antioxidants catechin and quercetin. this study investigates the effects of calligonum extract on sperm parameters and the rate of apoptosis in testes of aging male mice. methods: we initially performed a dose response test with using three doses of calligonum (10 mg/kg, 30 mg/kg and 50 mg/kg). ...

A descriptive information form, adult scale, scale were used for data collection. Results. levels low, ...

PURPOSE This study describes the development of a short version of the Expectations Regarding Aging Survey (ERA-38), a 38-item survey measuring expectations regarding aging. DESIGN AND METHODS In 1999, surveys containing the ERA-38 were mailed to 588 adults aged > or = 65 years who were recruited through physicians; 429 individuals (73%) returned completed surveys. The mean age of participant...
