Piracetam was subjected to the hydrolytic, oxidative, thermal and photolytic stress, according to ICH guideline Q1A (R2). The drug depicted degradation only in basic conditions, while it was stable to other stress conditions (acidic, neutral hydrolysis, thermal and photolytic conditions). A total of one degradation product was formed, which were separated on a BEH column employing an isocratic ...
Atypical or idiosyncratic language is a characteristic of autism spectrum disorder (ASD). In this paper, we discuss previous work identifying language errors associated with atypical language in ASD and describe a procedure for reproducing those results. We describe our data set, which consists of transcribed data from a widely used clinical diagnostic instrument (the ADOS) for children with au...
Thiol-containing compounds such as glutathione, cysteine and homocysteine react with selenite under specific conditions to form selenotrisulfides of significance in cellular systems. This study describes the synthesis and mass spectrometric characterization of selenotrisulfides of glutathione (GSH), cysteine (Cys) and homocysteine (HCys) by electrospray-MS (ESI-MS). The synthesized species are ...
BACKGROUND Multiple Sclerosis (MS) is one of the autoimmune diseases with an unknown cause. The aim of this study was to explore the link between air quality and MS relapses in patients who suffer from MS. METHODS This time-series study was conducted on patients registered at the Iranian Multiple Sclerosis Society in 2011-2012. They were randomly selected from patients lived in Tehran in the ...
Curcuma longa (turmeric) has been used in Chinese traditional medicine and Ayurvedic medicine for many years. METHODS The leaf essential oil of C. longa from southern Nigeria was obtained by hydrodistillation and analyzed by gas chromatography-mass spectrometry (GC-MS). The essential oil was screened for in vitro antibacterial, antifungal, and cytotoxic activities. The major components in C. ...
Patients —Texas, Arkansas, and Florida, 2008–2013 Anne Purfield, PhD; Snigdha Vallabhaneni, MD, MPH; Kaitlin Benedict, MPH; Shawn Lockhart, PhD; Cau Pham, PhD; Ulzii Luvsansharav, MD, PhD; Wendy Chung, MD, MSPH; Emily Hall, MPH; Jordan Peart; Neil Pascoe RN, BSN; Gary Heseltine, MD, MPH; Charlotte Wheeler, RN; Karen Brust, MD; Sharon Holmes, MPH; Prinu Gabriel, MS; Justin Groves, MPH; Craig Gil...
minutes after completing the submaximal test. Predicted VO2 was calculated from a submaximal treadmill test. An SVR exercise response coefficient (ERC) was derived and subjects were then categorized as normal response (NR) to exercise or abnormal response (AR) to exercise. Comparisons between groups were determined using ANOVA. RESULTS: The AR group indicated a significant blunted or even eleva...
An improved method to interpret triple quadrupole MS/MS experiments of complexes of large ions is presented and applied to a study of the complex formed by the proteins cytochrome c and cytochrome b5. Modeling of the activation and dissociation process shows that most of the reaction occurs near the collision cell exit where ions have the highest internal energies. Experiments at different coll...
An inversion procedure is used to obtain from the extended principle of corresponding - states the pair interaction potentials for argon, krypton and its mixture over a tetnperature range from absolute zero to the onset of ionization. The experimentally-reduced viscosity collision integrals obtained from the corresponding - states correlation have been inverted directly to give the reduced...
The aim of this investigation was to assess average Class III craniofacial growth in Japanese males and females, using cross-sectional data from infancy to adulthood. Growth was analysed using the centroid method. Centroid G was geometrically calculated from the triangle Delta abc, which comprised the palatal, articulare-gnathion (Ar-Gn), and A-B planes. Lateral cephalograms were obtained of 32...
