Numerical assessment of radiation binary targeted therapy for HER-2 positive breast cancers: advanced calculations and radiation dosimetry

In our previous publication (Mundy et al 2006 Phys. Med. Biol. 51 1377) we have described the theoretical assessment of our novel approach in radiation binary targeted therapy for HER-2 positive breast cancers and summarized the future directions in this area of research. In this paper we advanced the numerical analysis to show the detailed radiation dose distribution for various neutron sources in combination with the required boron concentration and allowed radiation skin doses. We once again proved the feasibility of the concept and will use these data and conclusions to start with the experimental verifications.     

Seroepidemiology of hepatitis E in patients on haemodialysis in Croatia

International Urology and Nephrology - Data on the seroprevalence of hepatitis E virus (HEV) in heamodialysis (HD) patients are conflicting, ranging from 0 to 44%. The aim of this study was to...     

Facial landmark localization by curvature maps and profile analysis

Over the last years, electronic cigarettes (ECs) have become more popular, particularly in individuals who want to give up smoking tobacco. The aim of the present study was to assess the influence of the different e-smoking liquids on the viability and proliferation of human periodontal ligament fibroblasts. For this study six test solutions with components from ECs were selected: lime-, hazelnut- and menthol-flavored liquids, nicotine, propylene glycol, and PBS as control group. The fibroblasts were incubated up to 96 h with the different liquids, and cell viability was measured by using the PrestoBlue® reagent, the ATP detection and the migration assay. Fluorescence staining was carried out to visualize cell growth and morphology. Data were statistically analyzed by two-tailed one-way ANOVA. The cell viability assay showed that the proliferation rates of the cells incubated with nicotine or the various flavored liquids of the e-cigarettes were reduced in comparison to the controls, though not all reductions were statistically significant. After an incubation of 96 h with the menthol-flavored liquid the fibroblasts were statistically significant reduced (p?相似文献   

In defense of psychosomatic theory: A critical analysis of Allison and Heshka's critical analysis

This article analyses Allison and Heshka's (International Journal of Eating Disorders, 13, 289–295, 1993.) critical analysis of studies supporting psychosomatic theory. Questionned first is, Allison and Heshka's contention that the obese overreport emotional eating as a result of effects of demand characteristics, social desirability, and interpersonal expectancies. These effects, however, indicate that a more plausible response would be an underreport of emotional eating. Also addressed is Allison and Heshka's (Eating Disorders: The Journal of Treatment and Prevention, 1, 31–38, 1993.) contention that a high correlation between a measurement instrument and a measure of social desirability invalidates that measurement instrument. Finally, in a rebuttal of Allison and Heshka's critical analysis of studies supporting psychosomatic theory, it is elaborated why emotional eating explains so little variance in weight gain and obesity. © 1995 by John Wiley & Sons, Inc.     

Guanidinoacetate–creatine in secondary progressive multiple sclerosis: a case report

Acute secondary progressive multiple sclerosis (SPMS) is characterized by escalating neurological disability, with limited disease-modifying therapeutic options. A 48-year-old woman with acute SPMS being treated with interferon beta-1a and oral corticosteroids presented as a clinical outpatient with no disease-modifying effects after treatment. A decision was made to treat her with a combination of guanidinoacetate and creatine for 21 days. She had made clinical progress at follow-up, with the intensity of fatigue dropping from severe to mild. Magnetic resonance spectroscopy revealed increased brain choline, creatine, N-acetylaspartate, and glutathione. Patients with SPMS may benefit from guanidinoacetate–creatine treatment in terms of patient- and clinician-reported outcomes; this requires additional study.
