Densities of aqueous solutions sulfuric acid (H2SO4) have been measured by vibrating tube densimetry at molalities m varying from 0.02 to 3.0 mol·kg–1, temperatures over the range 323.15 ≤ T/K 523.15 10 MPa pressure. These results were used calculate corresponding apparent molar volumes Vϕ(H2SO4,aq) and appear be first-ever systematic study volumetric properties this important elevated temperat...

OBJECTIVE To evaluate the reliability and accuracy of arcuate fasciculus (AF) navigation for AF localization and reconstruction. METHODS Reconstruction of the AF and assessment of the aphasia quotient (AQ) were performed in 43 cases before and after surgical removal of lesions in the language area of the brain. The minimal distance between the AF and the lesion (D(1)), preoperative AQ (AQ(1))...

The release of anthraquinone dyes from β-cyclodextrin modified, hyperbranched polyethylenimine (PEI-CD) was investigated. 5,8-Dichloro-1,4-dihydroxyanthraquinone (AQ-OH) was enclosed simply by ionic attraction between the phenolate groups of AQ-OH and the protonated amino groups of polyethylenimine (PEI). Additionally, the adamantyl moieties of 1,4-bis-N-adamantylaminoanthraquinone (AQ-Ada) wer...

This study measures the distribution of autistic traits, using the autism-spectrum quotient (AQ), in siblings of individuals with autism spectrum conditions (ASC). Total AQ scores, along with AQ subscales, were collected from child, adolescent and adult controls, siblings, and volunteers with ASC using one of the three age-appropriate versions of the instrument: the AQ (adult self-report), the ...

Densities of fifteen aqueous solutions sulfuric acid (H2SO4) have been measured by vibrating-tube densimetry at solute molalities (m) from (0.01 to 3.0) mol·kg−1 over the temperature range 293.15 ≤ T/K 343.15. These data used calculate corresponding apparent molar volumes Vϕ(H2SO4,aq), which represent a significant expansion volumetric database for this industrially-important acid. At 298.15 K ...

Amodiaquine (AQ) is an antimalarial which is effective against chloroquino-resistant strains of Plasmodium falciparum but whose clinical use is severely restricted because of associated hepatotoxicity and agranulocytosis. "One-pot" synthesis of formamidines likely to be transformed into AQ derivatives is reported. Compared with AQ, the new compounds were devoid of in vitro cytotoxicity upon hum...

OBJECTIVES Several products of artesunate plus amodiaquine (AS + AQ) are being deployed in malaria-endemic countries for treating uncomplicated falciparum malaria but dosing accuracy and consequential effects on efficacy and tolerability have not been examined. METHODS Patients with parasitologically confirmed, uncomplicated falciparum malaria were treated and followed by research teams or lo...

Resistance in Plasmodium falciparum to amodiaquine (AQ) can be reversed in vitro with with antihistaminic and tricyclic antidepressant compounds, but its significance in vivo is unclear. The present report presents the enhancement of the antimalarial efficacy of AQ by chlorpheniramine, an H1 receptor antagonist that reverses chloroquine (CQ) resistance in vitro and enhances its efficacy in vivo...

The Autism Spectrum Quotient-Children's Version (AQ-Child) is a parent-report questionnaire that aims to quantify autistic traits in children 4-11 years old. The range of scores on the AQ-Child is 0-150. It was administered to children with an autism spectrum condition (ASC) (n = 540) and a general population sample (n = 1,225). Results showed a significant difference in scores between those wi...

Using UV-vis spectrophotometic method, the formation constants for interaction of Cd2+(aq) andCo2+(aq) ions with L-Alanine were experimentally studied at pH = 4.1 ± 0.01 (50mM of potassiumhydrogen phthalate buffer), ionic strength of 0.1M potassium nitrate and at 5 differenttemperatures 15,20, 25,30 and 35°C. The optical absorption spectra of mixtures containingconsidered cations and L-Alanine ...
