Oral ATP treatment in alternating hemiplegia of childhood: a case report and review.

Alternating hemiplegia of childhood (AHC) is a rare neurological disorder that usually manifests before 18 months of age and is characterized by recurrent, alternating episodes of hemiparesis with variable frequency and can last from a few minutes to several days. We present a case of AHC in a little girl carrying a sporadic mutation in the ATP1A3 gene (p.Glu815Lys) refractory to flunarizine and non-compliant to topiramate due to adverse effects treated with oral compound of adenosine-5'-triphosphate (ATP) capsules.

Capillary Electrophoresis of Mono- and Oligosaccharides.

This chapter reports an overview of the recent advances in the analysis of mono- and oligosaccharides by capillary electrophoresis (CE); furthermore, relevant reviews and research articles recently published in the field are tabulated. Additionally, pretreatments and procedures applied to uncharged and acidic carbohydrates (i.e.

Capillary electrophoresis of sugar acids.

This chapter illustrates the usefulness of capillary electrophoresis (CE) for the analysis of sugar acids, that is, monosaccharides and lower oligosaccharides carrying carboxylate, sulphate or phosphate groups. In order to provide a general description of the main results and challenges in the field, some relevant applications and reviews on CE of such saccharidic compounds are tabulated. Furthermore, some detailed experimental procedures are shown, regarding the CE analysis of sugar acids released upon hydrolysis of acidic polysaccharides and of glycans linked to glycoproteins.

Overview on advances in capillary electrophoresis-mass spectrometry of carbohydrates: a tabulated review.

The increasing interest for carbohydrates as holder of essential bioinformations has boosted their full characterization through analytical techniques. The intent of this review is to summarize the recent trends regarding on-line and off-line CE-MS coupling for carbohydrate analysis. A statistical survey on the articles that use derivatizing agents as well as on the analyzer and type of instrument coupling (i.

Analysis of gadobenate dimeglumine by capillary zone electrophoresis coupled with electrospray-mass spectrometry.

Highly reliable and accurate analytical methods are needed for the determination of magnetic resonance imaging (MRI) contrast agents in complex matrices of clinical interest. We demonstrate the reliability of capillary zone electrophoresis (CZE) coupled with electrospray ionization-mass spectrometry (ESI-MS) for the analysis of MultiHance (gadobenate dimeglumine), a gadolinium-based MRI agent. A sheath liquid interface connected the CE system with an electrospray mass spectrometer equipped with an ion-trap analyzer.

Structure-dependent in vitro cytotoxicity of the isomeric complexes [Ru(L)2Cl2] (L= o-tolylazopyridine and 4-methyl-2-phenylazopyridine) in comparison to [Ru(azpy)2Cl2].

The dichlorobis(2-phenylazopyridine)ruthenium(II) complexes, [Ru(azpy)(2)Cl(2)], are under renewed investigation due to their potential anticancer activity. The three most common isomers alpha-, beta- and gamma-[RuL(2)Cl(2)] with L= o-tolylazopyridine (tazpy) and 4-methyl-2-phenylazopyridine (mazpy) (alpha indicating the coordinating Cl, N(pyridine) and Nazo atoms in mutual cis, trans, cis positions, beta indicating the coordinating Cl, N(pyridine) and Nazo atoms in mutual cis, cis, cis positions, and gamma indicating the coordinating Cl, N(pyridine) and Nazo atoms in mutual trans, cis, cis positions) are synthesized and characterized by NMR spectroscopy. The molecular structures of gamma-[Ru(tazpy)(2)Cl(2)] and alpha-[Ru(mazpy)(2)Cl(2)] are determined by X-ray diffraction analysis.

Automated parallel solid-phase synthesis and anticancer screening of a library of peptide-tethered platinum(II) complexes.

The automated parallel solid-phase synthesis of a 36-member library of peptide-tethered platinum(II) complexes is described. The identity and quality of each product were confirmed by mass spectrometry and (1)H NMR. Subsequently, each compound was screened for in vitro anticancer activity by treating the A2780 (human ovarian carcinoma) cell line with two concentrations of the drugs (100 and 10 microM) in quadruplicate.
