Abstract

BACKGROUND: Metabolic syndrome (MetS) and nephrolithiasis (NL) are quite common disorders. While some of the components of MetS have been proposed as precursors of NL in population studies, no data are available about the possible association between NL and MetS as such. The primary objective of the study was to evaluate the relationship between MetS and NL. The secondary outcome was to examine the relationship between MetS single constitutive elements and NL considering the strict correlation occurring among these factors. METHODS: We studied 2132 Caucasian inpatients of the 'Spinelli' Hospital in southern Italy (males/females = 0.95; mean age 63.8 +/- 15.8 years; body mass index 26.1 +/- 3.9 kg/m(2)). The MetS diagnosis was performed according to the Heart Association/National Heart, Lung, and Blood Institute criteria. The presence of NL was assessed by ultrasound examination of the kidneys and upper urinary tract. RESULTS: Seven hundred twenty-five subjects (34.0%) had a positive diagnosis of MetS. Two hundred twenty subjects (10.3%) had echographic evidence of NL, while 199 subjects reported a past history of NL (9.3%). The presence of MetS, as well as the male sex, and the occurrence of a previous episode of NL (in male subjects only) were each independently related to echographic evidence of NL. Among the individual components of MetS, high blood pressure and abdominal obesity (in female individuals only) were also independently related to echographic evidence of NL. CONCLUSIONS: MetS is significantly associated with echographic evidence of NL. A gender-related difference in the clinical expression of NL was also observed.

7. Luminescent rise times of inorganic phosphors excited by high intensity ultraviolet light.

Author

Anderson RJ and Ricchio SG

Abstract

The relative delay between excitation and luminescence was measured for a number of common inorganic phosphors using short, high intensity excitation pulses. The delays were found to be much shorter than anticipated; on the basis of low intensity pulsed luminescence measurements and were found to be extremely intensity-dependent. Both the luminescence rise and decay times were found to be intensitydependent as well, with the luminescence pulse waveform tending to approach the exciting pulse at the higher excitation intensities.
