65 cm(2)/m(2)) and dysfunctional (EOA(i) < 0.65 cm(2)/m(2)) AVRs were compared.

Results:

AVA at CT correlated highly to EOA at TTE (r = 0.93, P < .001) but was significantly larger (1.2 cm(2) +/- 0.4 vs 1.1 cm(2) +/- 0.3, P < .001) than EOA at TTE. In dysfunctional bioprostheses (n = 34), CT results showed a variety of morphologic abnormalities, such as leaflet thickening (n = 9), presumed thrombotic material (n = 6), and leaflet calcification (n = 1). Multidetector CT results demonstrated restriction of leaflet motion indicated by lower OA (64 degrees +/- 5 vs 79 degrees +/- 3, P < .0001) in dysfunctional AVRs than in normally functioning AVRs (n = 11).

fluid to plasma glycine ratio are considered pathognomonic of nonketotic hyperglycinemia. To evaluate the significance of cerebrospinal fluid hyperglycinemia and elevated cerebrospinal fluid to plasma glycine ratio in acutely encephalopathic infants, a retrospective chart review of all cases of isolated elevation of cerebrospinal fluid glycine levels at Arkansas Children’s Hospital from January 1995 to December 2000 was performed. Twenty-two patients (14 males) were included. The most common diagnosis was hypoxic ischemic encephalopathy (n = 8). Nine patients had elevated cerebrospinal fluid to plasma glycine ratio, which was transient in 7 patients. This study shows that elevated cerebrospinal fluid to plasma glycine ratio can be encountered in a variety of clinical conditions. The significance of this observation in light of the poor prognosis of nonketotic hyperglycinemia and

the possible role of glycine in the mechanism of ischemic neuronal injury is addressed.”
“Pd nanoparticles (NPs) were Salubrinal mw prepared by focused femtosecond laser irradiation of PdCl2 dissolved in ethanol. Transmission electron microscopy (TEM) analysis revealed that Pd NPs show certain crystalline microstructure, and the average diameter is 3.4 nm with narrow size distribution from 2.0 to 6.0 nm. The nonlinear optical absorption and refraction of Pd NPs solution were investigated with nanosecond laser pulses at 532 nm. The nonlinear absorption of Pd NPs is saturable at low intensity of 3.28 X 10(11) W/m(2) but it is changed to reverse saturable with the intensity increased to 7.96 X 10(11) W/m(2), which accordingly indicates the nonlinear refraction is changed from self-defocusing to self-focusing. The transition of the nonlinear absorption with the increase in pulse intensity is analyzed by an empirical model which includes mostly saturable absorption (SA) and two-photon absorption (TPA).
