The measured epsilon(E) spectra reveal distinct structures at several interband critical points in the Brillouin zone of beta-Sn. These spectra are analyzed on the basis of a simplified model of the interband transitions, including the free-carrier absorption between the filled and empty electronic states. Dielectric-related optical constants, such as the complex refractive index, absorption coefficient, and normal-incidence
reflectivity, of bulk beta-Sn films are also presented. (C) 2009 American Institute of Physics. [DOI:10.1063/1.3106528]“
“Objective. Migraine is a common type of headache accompanied or preceded by signs of central and autonomic nervous system dysfunction. Autonomic dysfunction click here has been suggested to be a potential contributor to impaired cardiac diastolic function. Cardiac diastolic dysfunction
is characterized by normal left ventricular contractility but impaired ventricular relaxation. It is a growing clinical entity implicated in morbidity and mortality due to heart failure. The aim of this study was to determine if any relationship exists between migraine and diastolic dysfunction.
Methods. Migraineurs (N = 55), and age- and sex-matched healthy controls (N CP456773 = 52) were evaluated by conventional and tissue Doppler echocardiography. Migraine-related disability in the previous 3 months was assessed by the Migraine Disability Assessment questionnaire. Baseline characteristics were recorded, and blood samples were collected.
Results. The groups did not differ in terms of sex or age. The migraine group had higher lipid levels compared with the control group. Diastolic dysfunction was significantly higher among the 30 migraineurs with a history of migraine of 10 years or more compared with the 25 migraineurs with a history of less than 10 years, (P = 0.003). In logistic regression analysis, migraine duration was
shown to be an independent predictor of diastolic dysfunction (odds ratio 1.130, 95% confidence interval, P = 0.044).
Conclusions. Cardiac diastolic dysfunction is associated with migraine. A long history of migraine is an independent predictor of diastolic dysfunction.”
“This present study was performed to investigate estrogenic activity of Korean edible wild plants for alternative of estrogen replacement SN-38 nmr therapy in postmenopausal women. When the estrogenic activity was measured by estrogen induced proliferation of MCF-7 cells, of investigated 29 extracts, 3 samples of kudzu vine (Pueraria thunbergiana), Cardamine leucantha, and David Vetchling (Lathyrus davidii) exhibited a significant proliferation of above 20% at concentration of 100 mu g/mL. This stimulation of MCF-7 cell proliferation could be completely blocked by addition of estrogen antagonist ICI 182,780 (100 nM), indicating estrogen receptor-dependent mechanism of these estrogenic effects on MCF-7 cell proliferation.
