Purified Membrane-Containing Procapsids of Bacteriophage PRD1 Package the Viral Genome
2009
Icosahedral-tailed double-stranded DNA (dsDNA) bacteriophages and herpesviruses translocate viral DNA into a preformed procapsid in an ATP-driven reaction by a packaging complex that operates at a portal vertex. A similar packaging system operates in the tailless dsDNA phage PRD1 (Tectiviridae family), except that there is an internal membrane vesicle in the procapsid. The unit-length linear dsDNA genome with covalently linked 5'-terminal proteins enters the procapsid through a unique vertex. Two small integral membrane proteins, P20 and P22, provide a conduit for DNA translocation. The packaging machinery also contains the packaging ATPase P9 and the packaging efficiency factor P6. Here we…
Kosteneffektivitätsanalyse der Versorgung von Kataraktpatienten mit monofokalen Intraokularlinsen aus Sicht der Leistungserstatter
2003
BACKGROUND Data on the cost effectiveness of cataract surgery with respect to the German statutory health insurance system are hardly available. Hence the increase in visual acuity as primary efficacy endpoint, order of posterior capsule opacification as primary complication endpoint and direct cost for supplementation with monofocal intraocular lenses have been assessed via meta-analyses to evaluate the procedure's cost effectiveness from the perspective of the German statutory health insurance system. MATERIAL AND METHODS Using the medical internet database MEDLINE two meta-analyses on publications between 1995 and 2002 were carried out, one estimating the gained increase in visual acuity…
A novel alpha-amylase-lipase formulation as anti-staling agent in durum wheat bread
2016
The aim of this work has been to evaluate the anti-staling effect exerted by a novel α-amylase-lipase enzyme formulation on durum wheat bread, in comparison with four different commercial amylase preparations and with control without added enzymes. Bread-making trials were carried out at industrial level. Sliced bread, packed under modified atmosphere, was analyzed for texture profile, moisture content, and water activity during 90 days. Crumb sections were submitted to environmental scanning electron microscopy at the end of the storage period. The α-amylase-lipase enzyme preparation showed synergistic interactions in preventing staling. In particular, bread added of these two enzymes in m…

Breeding on man made structures has never been cited in literature for this species. First records of breeding in windmill in the saltpans of Trapani are here reported.
Creatine kinase is the main target of reactive oxygen species in cardiac myofibrils.
1996
Abstract Reactive oxygen species (ROS) have been reported to alter cardiac myofibrillar function as well as myofibrillar enzymes such as myosin ATPase and creatine kinase (CK). To understand their precise mode and site of action in myofibrils, the effects of the xanthine/xanthine oxidase (X/XO) system or of hydrogen peroxide (H 2 O 2 ) have been studied in the presence and in the absence of phosphocreatine (PCr) in Triton X-100–treated cardiac fibers. We found that xanthine oxidase (XO), with or without xanthine, induced a decrease in maximal Ca 2+ -activated tension. We attributed this effect to the high contaminating proteolytic activity in commercial XO preparations, since it could be p…
Kinetic modelling of the Zymomonas mobilis Entner-Doudoroff pathway: insights into control and functionality.
2013
Zymomonas mobilis, an ethanol-producing bacterium, possesses the Entner-Doudoroff (E-D) pathway, pyruvate decarboxylase and two alcohol dehydrogenase isoenzymes for the fermentative production of ethanol and carbon dioxide from glucose. Using available kinetic parameters, we have developed a kinetic model that incorporates the enzymic reactions of the E-D pathway, both alcohol dehydrogenases, transport reactions and reactions related to ATP metabolism. After optimizing the reaction parameters within likely physiological limits, the resulting kinetic model was capable of simulating glycolysis in vivo and in cell-free extracts with good agreement with the fluxes and steady-state intermediate …
Somu zīmolu atpazīstamība Latvijas iedzīvotāju vidū
2021
Bakalaura darba tēma ir “Somu zīmolu atpazīstamība Latvijas iedzīvotāju vidū”. Pētījuma mērķis ir noskaidrot patērētāju viedokli par zīmoliem Fazer un Lumene un novērtēt to atpazīstamību Lavijas iedzīvotāju vidū. Bakalaura darbs sastāv no trīs daļām: teorētiskās daļas, metodoloģiskās daļas un empīriskās daļas. Teorētiskā daļa sastāv no divām galvenajām nodaļām: zīmols un tā atpazīstamība, somu zīmoli Fazer un Lumene. Kā pētniecības metode tiek izmantota aptauja interneta vidē. Apkopotie empīriskās daļas rezultāti sniedz informāciju par patērētāja attieksmi pret somu zīmoliem Fazer un Lumene un sniedz informāciju par šo zīmolu atpazīstamību Latvijas iedzīvotāju vidū. Galvenais pētījuma rezul…

cIAP1 oncogenic properties analysis : contribution of its partners cdc42 and E2F1
2014
The inhibitor of apoptosis protein cIAP1 (cellular inhibitor of apoptosis protein-1) from the IAP family (Inhibitor of Apoptosis Protein) is an oncogene with an E3 ubiquitin ligase activity. cIAP1 is relocalized from the nucleus to the cytoplasm during the differentiation of many kind of cellular models (macrophages, dendritic cells, colon epithelial cells, hematopoietic stem cells, cardiomyocytes) and this relocalization is associated with a proliferation arrest. The well-known functions of cIAP1 are associated with its cytoplasmic localization, where it regulates the TNFa receptors and NF-?B signaling pathways. However, cIAP1 is mainly expressed in the nucleus on many cell types which is …
