Noninvasive ablation of cardiac arrhythmia by scanned particle radiotherapy is highly promising, but especially challenging due to cardiac and respiratory motion. Irradiations for catheter-free ablation in intact pigs were carried out at the GSI Helmholtz Center in Darmstadt using scanned carbon ions. Here, we present real-time electrocardiogram (ECG) data to estimate time-resolved (4D) delivered dose. For 11 animals, surface ECGs and temporal structure of beam delivery were acquired during irradiation. R waves were automatically detected from surface ECGs...

Drynariae Rhizoma is a kidney-tonifying herb that has a long history in clinical practice for the treatment of bone fractures and joint diseases in China. Flavonoids are considered to be its major active ingredients and are reported to ease bone loss in ovariectomized rats. However, the beneficial effects of the total flavonoids of Drynariae Rhizoma on osteoporosis caused by microgravity or mechanical inactivity remain unknown. This study assessed the effects of total Drynariae Rhizoma flavonoids (DRTF, Qihuang, Beijing, China, national medicine permit No...

Adolescents in sub-Saharan Africa are at risk for contracting HIV. Although media campaigns have educated the population as a whole, few studies are available about the time sub-Saharan African youth spend listening to and viewing sexual messages via the entertainment and informational media. The goals of this project were: 1) to investigate what programming Nairobi adolescents access; and 2) to investigate the association between frequency of access and level of focus on physical relationships with adolescents' perceptions of descriptive norms of peer sexual behaviour, and their attitudes regarding men as sex driven, women as sex objects, and dating as a sport...

As the number of elderly orthodontic patients increases, the impact of postmenopausal osteoporosis on orthodontic tooth movement (OTM) has attracted a great deal of attention because OTM relies on alveolar bone remodeling. The question of whether OTM causes subsequent alveolar bone loss and is harmful to alveolar bone health under osteoporotic conditions remains to be answered. The present study aimed to clarify the influences of OTM on alveolar bone in osteoporotic rats. OTM was accelerated in ovariectomized (OVX) rats as a result of increased bone resorption in the pressure area...

Sedentary behavior has emerged as an independent cardiovascular disease risk factor. Uncertainty exists about the behaviors of statin users, who may exhibit either a healthy adherer or a false reassurance effect. We conducted this study in order to assess and compare TV viewing among statin users and nonusers. We used data from a cross-sectional study of 12,754 participants, from south-east Poland, age 45 to 64 years in 2010-11. Statin use during last 30 days was recorded by trained nurses. Participants reported time spent viewing TV/week...

Entertainment persuasion theory was applied to investigate how an epilogue to a dramatic episode with an educational subtext about bipolar disorder affected viewer processing and response. In an experiment, viewers (N = 89) were randomly assigned to watch the episode either with or without an epilogue. Exposure to the epilogue increased recognition of the subtext. It also increased counterarguing against the subtext, but only among viewers less involved with the episode's story. The epilogue decreased social distance for people with bipolar disorder and decreased their belief that bipolar disorder is not treatable...

AIMS: Trichomonas vaginalis (TV) prevalence varies among different communities and peoples. The availability of robust molecular platforms for the detection of TV has advanced diagnosis; however, molecular tests are more costly than phenotypic methodologies, and testing all urogenital samples is costly. We recently replaced culture methods with the Aptima Trichomonas vaginalis nucleic acid amplification test on specific request and as reflex testing by the laboratory, and have audited this change...

PURPOSE: The authors recently developed a preconditioned alternating projection algorithm (PAPA) for solving the penalized-likelihood SPECT reconstruction problem. The proposed algorithm can solve a wide variety of non-differentiable optimization models. This work is dedicated to comparing the performance of PAPA with total variation (TV) regularization (TV-PAPA) and a novel forward-backward algorithm with nested expectation maximization (EM)-TV iteration scheme (FB-EM-TV). METHODS: Monte Carlo technique was used to simulate multiple noise realizations of the fan-beam collimated SPECT data for a piecewise constant phantom with warm background, and hot and cold spheres with uniform activities at two noise levels...
