Multivariate optimization approach for chiral resolution of drugs using human serum albumin in affinity electrokinetic chromatography-partial filling…
2005
The enantiomeric resolution of chiral compounds using HSA by means of affinity EKC (AEKC)-partial filling technique is the result of a delicate balance between different experimental variables such as protein concentration, running pH (background electrophoretic buffer, protein and compound solutions) and protein solution plug length. In this paper multivariate optimization approaches for chiral separation of four basic drugs (alprenolol, oxprenolol, promethazine and propranolol) using HSA as chiral selector in AEKC-partial filling technique are studied. The experimental conditions to achieve maximum resolution are optimized using the Box-Behnken experimental design. Partial least squares a…
Prognostisch relevante Faktoren beim Carcinom der Papilla Vateri
1989
In order to evaluate the relevant factors for prognosis for patients with cancer of Vater's papilla our own patient material between 1. 1. 1978 and 31. 12. 1987 was studied retrospectively. The influence of age, sex, duration of anamnesis, tumor size, tumor morphology and tumor stage on the prognosis were analyzed in 32 patients with cancer of Vater's papilla. The 5 year survival rate after Whipple procedure was 56.1%. Statistically significant factors for prognosis were tumor size, lymph node metastases and tumor stage.
Ancestral Reconstruction and Investigations of Genomic Recombination on some Pentapetalae Chloroplasts
2019
Abstract In this article, we propose a semi-automated method to rebuild genome ancestors of chloroplasts by taking into account gene duplication. Two methods have been used in order to achieve this work: a naked eye investigation using homemade scripts, whose results are considered as a basis of knowledge, and a dynamic programming based approach similar to Needleman-Wunsch. The latter fundamentally uses the Gestalt pattern matching method of sequence matcher to evaluate the occurrences probability of each gene in the last common ancestor of two given genomes. The two approaches have been applied on chloroplastic genomes from Apiales, Asterales, and Fabids orders, the latter belonging to Pe…
Informatīvā paneļa "InfoDesk" izstrāde
2015
Darbā ir aprakstīts slīdrādes rīka „InfoDesk” funkcionalitātes paplašināšana, atkļūdojot un papildinot to. „InfoDesk” nodrošina slaidu veidošanu, konfigurējamību un slīdrādi uz Android ierīcēm ar API līmeni 14 vai augstāk. Pirms kvalifikācijas darbā aprakstītajām izmaiņām „InfoDesk” spēja izveidot slaidus, tos atskaņot, kā arī konfigurēt tos, bet katrā no šīm darbībām programma varēja pātraukt darboties. „InfoDesk” klāt pievienotā funkcionalitātē ietilpst plašāka slaidā pievienoto elementu kontrole, saglabāšana uz ārējas atmiņas ierīces, labāka atmiņas lietošana, vispārēja programmatūras stabilitāte. Sistēma realizēta Java programmēšanas valodā, izstrādes vidēs Eclipse un Android Studio.
Reporting, Reflecting and Recognising Emotions in Therapeutic Work with Domestic Violence Perpetrators : Experiences of the Jyväskylä Group Model
2020
Emotions are central in therapeutic work, but interventions for violence vary in how they address emotions. While emotional work with perpetrators is often associated with ‘anger management’ and behavioural elements, a more comprehensive view of emotions might be beneficial in efforts to stop and prevent violent behaviour. Perpetrators’ self-regulation can be promoted by recognising and addressing primary feelings (vulnerability, fear, jealousy, etc.) that may manifest as anger and aggressive behaviour. However, this kind of therapeutic work with perpetrators of violence is also challenging for professionals. For example, when working towards ending violence, it is crucial to differentiate …

Characterization of poly(4-vinylpyridine 1-oxide) by free-solution capillary electrophoresis and micellar electrokinetic chromatography
2008
The migration characteristics of poly(4-vinylpyridine 1-oxide) (PVP-NO) in phosphate buffers of acidic pH (20 mM H 3 PO 4 or NaH 2 PO 4 ) have been studied using both free-solution capillary electrophoresis (FSCE) and MEKC. To inhibit adsorption, 250 mM o-phosphoethanolamine (2-aminoethyl dihydrogen phosphate) was used. In FSCE, PVP-NO showed a narrow peak and a broader band, both having anionic behavior. These peak and band were attributed to the free and aggregated or micellized PVP-NO forms, respectively. According to surface tension measurements, the CMC of SDS in the BGE was 1.8 and 0.48 mM in the absence and in the presence of 1000 μpg/mL PVP-NO, respectively, and the association of t…
Characterization and determination of poly(vinylpyrrolidone) by complexation with an anionic azo-dye and nonequilibrium capillary electrophoresis
2009
Using capillary zone electrophoresis in nonequilibrium conditions, the complexes of poly(vinylpyrrolidone) (PVP) with anionic azo-dyes dissociate following a first-order kinetics. Two peaks due to the remaining PVP-dye complexes and the equilibrium concentration of the free dye, plus an exponential region due to the dye liberated by the complexes during the electrophoretic run, are obtained. This behaviour was closely similar to that described in the literature for protein-probe and DNA-protein mixtures, upon application of the technique known as nonequilibrium capillary electrophoresis of equilibrium mixtures or NECEEM. Using Congo Red and Acid Blue 113, information about the maximal stoic…
