Capillary electrophoresis method for the determination of (R)-dapoxetine, (3S)-3-(dimethylamino)-3-phenyl-1-propanol, (S)-3-amino-3-phenyl-1-propanol and 1-naphthol as impurities of dapoxetine hydrochloride.

A capillary electrophoresis method was developed and validated for the determination of the purity of dapoxetine with regard to the related substances (3S)-3-amino-3-phenylpropan-1-ol, (3S)-3-(dimethylamino)-3-phenylpropan-1-ol, 1-naphthol and the enantiomer (R)-dapoxetine. The separation was based on a dual selector system, which was optimized by a fractional factorial resolution V + design followed by a central composite face centered design with star distance 1 and Monte Carlo simulations for defining the design space. The optimized background electrolyte consisted of a 50 mM sodium phosphate buffer, pH 6.

How 'The Urge to Kill' Feels: Articulations of Emic 'Appetitive Aggression' Experiences Among Former Forcefully Recruited Children and Youth in the Acholi Region of Northern Uganda.

Based on 10 months of fieldwork in the Acholi region of northern Uganda among youth and adults who were forcefully recruited into the Lord's Resistance Army (LRA) during the war, this article provides qualitative details to research on 'appetitive aggression.' Through two case-stories the article unfolds first person articulations of how 'appetitive aggression' is experienced as 'the urge to kill' and how it relates to the emic Acholi spiritual concept of 'cen'; a local Luo expression used to describe places and human beings possessed by evil spirits. The analysis illuminates what the individual and social implications of 'the urge to kill' and 'cen' entail for two Acholi men; first in a militia and then in a civil post-war context.

"What kept me going": A qualitative study of avoidant responses to war-related adversity and perpetration of violence by former forcibly recruited children and youth in the Acholi region of northern Uganda.

This qualitative study investigates what, according to 36 former forcibly recruited women and men, enabled them to "keep on going" during and after their forced recruitment in the twenty-year-long civil war in northern Uganda. Furthermore, the study conveys the ways most of the former forcibly recruited kept on going and today cope with ongoing war-related adversity and difficult reintegration processes without relying on psycho-social intervention. Thirty-five of the 36 women and men were forcibly recruited when they were children by the Lord's Resistance Army (LRA) from the Acholi region of northern Uganda.

Development and validation of a capillary electrophoresis method for the characterization of sulfoethyl cellulose.

To characterize sulfoethyl cellulose el samples, a capillary electrophoresis method was developed and validated sulfoethyl cellulose el was hydrolyzed, and the resulting d-glucose derivatives were analyzed after reductive amination with 4-aminobenzoic acid using 150 mM boric acid, pH 9.5, as background electrolyte at 20°C and a voltage of 28 kV. Peak identification was derived from capillary electrophoresis with mass spectrometry using 25 mM ammonia adjusted to pH 6.

Enantiomer Separations by Capillary Electrophoresis.

Capillary electrophoresis (CE) is a versatile and flexible technique for analytical enantioseparations. This is due to the large variety of chiral selectors as well as the different operation modes including electrokinetic chromatography, micellar electrokinetic chromatography, and microemulsion electrokinetic chromatography. The chiral selector, which is added to the background electrolyte, represents a pseudostationary phase with its own electrophoretic mobility allowing a variety of different separation protocols.

A retrospective analysis of patients referred for implant placement to a specialty clinic: indications, surgical procedures, and early failures.

Purpose: This retrospective study analyzed the pool of patients referred for treatment with dental implants over a 3-year period in a referral specialty clinic.

Materials And Methods: All patients receiving dental implants between 2002 and 2004 in the Department of Oral Surgery and Stomatology, University of Bern, were included in this retrospective study. Patients were analyzed according to age, gender, indications for implant therapy, location of implants, and type and length of implants placed.

Clinical performance of wide-body implants with a sandblasted and acid-etched (SLA) surface: results of a 3-year follow-up study in a referral clinic.

Purpose: The aim of this study was to evaluate the 3-year success rates of wide-body implants with a regular- or wide-neck configuration and a sandblasted, large grit, acid-etched (SLA) surface.

Materials And Methods: A total of 151 implants were consecutively placed in posterior sites of 116 partially edentulous patients in a referral clinic at the School of Dental Medicine, University of Bern. All implants were restored with cemented crowns or fixed partial dentures after a healing period of 6 to 8 weeks (for implants placed without simultaneous bone augmentation) or 10 to 14 weeks (for implants with simultaneous bone augmentation).

[Intraoral lipoma in the region of the mental nerve--report of a case and review of the literature].

The intraoral lipoma is a benign, slowly growing, painless soft tissue neoplasia, which can cause esthetic or functional problems for the patient, depending on its size. All parts of the body can be affected, whereas the oral cavity is rarely involved. Clinically, the tumour often exhibits an exophytic growth pattern, a soft consistency, a broad base connected to the underlying tissue, and frequently has a reddish-yellowish colour.

[White sponge naevus. Report of a family with respect to histopathologic, cytopathologic and DNA-cytometric aspects].

The white sponge naevus is a rare benign, hereditary autosomal dominant disorder of the mucosa. The oral mucosa is most often affected, but vaginal and anal mucosal surfaces may also be involved. Clinically, a whitish-grey, ragged, and folded surface that has no clear demarcation and appears sponge-like is characteristic, often creating problems in differential diagnosis.

[Purification and various properties of NADP+-dependent alcohol dehydrogenase from Acinetobacter calcoaceticus].

The constitutive NADP+-dependent alcohol dehydrogenase from Acinetobacter calcoaceticus can be accumulated about 50 fold in 3 purification steps. The end-product shows in the analytical polyacrylamide gel electrophoresis only one active enzyme band. The molecular weight of the enzyme was determined to be 235,000 by gel chromatography on Sephadex G 200, the smallest subunit shows a molecular weight of 61 000 on SDS electrophoresis.
