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...

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...

Haponiuk, Sreeraj GopiAbstractBionanocomposites prepared from green sources are a promising research area and cellulose nanofibers obtained from agro-waste of ginger rhizomes and their different composites with starch, chitosan (CS) and polyvinyl alcohol (PVA) have exhibited enormous mechanical as well as antimicrobial properties. This paper reports the synthesis of magnetic ginger nanofiber (M-GNF) reinforced composite films with CS, PVA and potato starch (PS) by Fe3O4 ...

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 ...

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...

The main objective of this study was to assess the long-term consistency of rsfMRI connectivity maps derived at multiple sites and vendors using the Canadian Dementia Imaging Protocol (CDIP, www.cdip-pcid.ca...

JonesAbstractBreathing rate and depth influence the concentration of carbon dioxide in the blood, altering cerebral blood flow and thus functional magnetic resonance imaging (fMRI) signals. Such respiratory fluctuations can have substantial influence in studies of fMRI signal covariance in subjects at rest, the so-called “resting state functional connectivity” technique. If respiration is monitored during fMRI scanning, it is typically done...

Despite the dynamic nature of the brain's functional architecture, characterizing its temporal stability within a continuous state has been largely neglected. Here we characterized stability of functional architecture at a dynamic timescale (∼1 min) for each brain voxel by measuring the concordance of dynamic functional connectivity (DFC) over time, compared between association and u...

Current ex vivo methods employed to provide 3D fiber orientations have limitations, including tissue-distorting sample preparation, small field of view or inability to quantify 3D fiber orienta...
