ConclusionsThis case series demonstrates that the use of a high frequency jet ventilator for cardiac MRI was feasible, safe, providing good quality cardiac imaging and avoiding anesthesia personnel to be inside the hazardous environment of MRI room. Future studies are needed to confirm its safety and efficiency in pediatric patients.ResumoJustificativa e objetivosA ressonância magnética (RM) cardíaca é uma técnica utilizada na avaliação de crianças com cardiopatias congênitas. A anestesia geral garante imobilidade, especialmente em pacientes não cooperador...

ChenAbstractA 42-year-old woman presented with a ten-day history of dysphagia, slight chest pain and occasional vomiting. With the performance of thoracic and abdominal enhanced computed tomography (CT) and upper gastrointestinal contrast, once esophageal cancer was suspected. Significant activity mass in esophagus and mediastinal lymph nodes could be found on the imaging of 18F-FDG PET/CT, which also supported malignancy. However, T...

Publication date: Available online 12 October 2019Source: Materials Today: ProceedingsAuthor(s): A. Saikiran, M. Vivekanand, M. Prahalad, S. Yuvan, N. RameshbabuAbstractMicrowave synthesis of nanocrystalline Zn/Mg substituted and Zn/Mg-F co-substituted hydroxyapatites is reported in this study. Substitution of Zn/Mg is expected to increase the bioactivity, whereas the fluorine substitution is aimed for the attainment of chemical and thermal stability of the hydroxyapatite. The thermal stability of the nanopowders was studied by annealing the samples at 900 °C for 2 h. The phase composition and crystallite size of t...

Dlamini, Zhenyu Cui, Jianxin LiAbstractPolysulfone (PSF) and Styrene Maleic Anhydride (SMA) were blended by thermally induced phase separation method in the preparation of membranes for water treatment. Dipropylene Glycol Dibenzoate (DPGDB) was used as a diluent which was extracted using ethanol. The increase in SMA concentration was positively confirmed by monitoring the intensity of the peak at 1779 cm−1 characteristic to CO in the Attenuated Total Reflectance Fourier Transform In...

ConclusionsPKD can be a manifestation of PFBC, and brain calcification may be a cause of secondary PKD. So thoroughly evaluation including head CT or genetic screening for paroxysmal dyskinesia and PFBC should be applied before the diagnosis of PKD or PFBC. Moreover, negative brain calcification may not exclude the possibility of PFBC. The possible pathogenesis of primary calcification lie in the dysfunction of the protein or defective signal transduction caused by the mutations.

However, existing research to date has focused on sex hormones associated with gonadarche. Given the role of the pituitary gland in hypothalamic-pituitary-adrenal (HPA) axis function, the present study investigated associations between PGV development and HPA hormones that play ...

ConclusionsThe current rapid, multi-slice acquisition and real-time implementation of temperature and displacement visualization may be useful in clinical practices. It may help defining operational safety margins, improving therapy precision and efficacy. Simulations were in good agreement with experimental data and may thus be used prior treatment for procedure planning.

Hubbard, Yuguang Zhao, Bart Rypma, Lars BäckmanAbstractFacial recognition ability declines in adult aging, but the neural basis for this decline remains unknown. Cortical areas involved in face recognition exhibit lower dopamine (DA) receptor availability and lower blood-oxygen-level-dependent (BOLD) signal during task performance with advancing adult age. We hypothesized that changes in the relationship between these two neural systems are related to age differences i...
