Mechanisms of HAMLET-induced cancer cell death

HAMLET, a complex of α-lactalbumin and oleic acid, preferentially kills cancer cells and is also effective in vivo. HAMLET causes apoptosis but cells die even if this pathway is inhibited. Thus, the role of autophagy, an alternative cell death pathway, was examined. During autophagy double membrane-enclosed autophagosomes form around cellular material and deliver it to the lysosomes for degradatio

Association of maternal serum concentrations of 2,2 ', 4,4 ' 5,5 '-hexachlorobiphenyl (CB-153) and 1,1-dichloro-2,2-bis (p-chlorophenyl)-ethylene (p,p '-DDE) levels with birth weight, gestational age and preterm births in Inuit and European populations

Background: Epidemiological studies on the association between maternal exposure to persistent organic pollutants (POPs) and fetal growth alteration report inconsistent findings which weights in favor of additional studies. Methods: Blood samples were collected from interviewed pregnant women in Greenland (572), Kharkiv (611) and Warsaw (258) and were analyzed for CB-153 and p,p'-DDE by gas chroma

A simple one-step assay platform based on fluorescence quenching of macroporous silicon

We synthesized 3D macroporous silicon through a simple electrochemical dissolution process and systematically estimated its protein adsorption and effect on fluorescence emission. Compared with conventional 2D polystyrene plate, the macroporous silicon showed a superior protein adsorption capacity and significant fluorescence quenching effect. We developed a 3D macroporous silicon-based adenosine

The Swedish version of OMAS is a reliable and valid outcome measure for patients with ankle fractures

Background: The aim of this study was to evaluate the test-retest reliability and the validity of the self-reported questionnaire Olerud-Molander Ankle Score (OMAS) in subjects after an ankle fracture. Methods: When evaluating the test-retest reliability of the OMAS, 42 subjects surgically treated due to an ankle fracture participated 12 months after injury. OMAS was completed by the patients on t

CPU Resource Management and Noise Filtering for PID Control

The first part of the thesis deals with adaptive CPU resource management for multicore platforms. The work was done as a part of the resource manager component of the adaptive resource management framework implemented in the European ACTORS project. The framework dynamically allocates CPU resources for the applications. The key element of the framework is the resource manager that combines feedfor

Register studies of cancer in the Southern Health Care Region in Sweden

Popular Abstract in Swedish Södra Regionvårdsnämnden har önskat att få belyst om vi har en rättvis och jämlik cancervård i Södra sjukvårdsregionen. Därför har en populationsbaserad registerstudie med många olika etapper genomförts. Basinformationen har hämtats från Tumörregistret i Södra sjukvårdsregionen. Första diagnosdatum noterades och hemort (kommun, distrikt, län) samt sjukhus definierades eThe overall aim was to study different aspect of health care use and health care costs on a population based level for persons with cancer and their partners, and from an individual level to explore the impact of comorbidities in incidence and survival. In the beginning of the study all persons in the Southern Health Care Region in Sweden diagnosed with colon, rectal, breast, prostate and lung can

Explaining spatial patterns of innovation: analytical and synthetic modes of knowledge creation in the Medicon Valley life-science cluster

The authors address the dichotomy around 'proximate' and 'distant' learning processes by looking specifically at the characteristics of the knowledge-creation process. By way of suggesting an alternative conceptualization to the well-known tacit-codified knowledge dichotomy, they propose a distinction between 'analytical' and 'synthetic' modes of knowledge creation. Analytical knowledge creation r

Objective social outcomes index (SIX): a method to summarise objective indicators of social outcomes in mental health care

Objective: No method has yet been established to summarise different objective indicators of social outcomes into one score. The study aimed to develop and test a simple, brief and meaningful index of social outcomes that can be used across a broad range of mental health studies and is potentially obtainable from routine documentation. Method: An index capturing employment, accommodation and livin

Humidity sensing properties of bismuth phosphates

Cubic sillenite-type and monoclinic bismuth phosphates were synthesized via hydrothermal methods. Structure and morphology of cubic Bi13.1PO delta and monoclinic BiPO4 were characterized with a variety of analytical methods including powder X-ray diffraction, electron microscopy methods and surface area measurements. The humidity sensing properties of both bismuth phosphate types were investigated

An Interactive Mapping Tool to Assess Individual Mobility Patterns in Neighborhood Studies

As their most critical limitation, neighborhood and health studies published to date have not taken into account nonresidential activity places where individuals travel in their daily lives. However, identifying low-mobility populations residing in low-resource environments, assessing cumulative environmental exposures over multiple activity places, and identifying specific activity locations for

Systemoptimerad produktion av fordonsgas - En miljö- och energisystemanalys av Söderåsens biogasanläggning

Syftet med föreliggande studie är att presentera en energi- och miljösystemanalys för en specifik biogasanläggning samt att beskriva och kostnadsberäkna åtgärder för att optimera systemet. En övergripande målsättning är också att studien ska kunna fungera som modell för kommande energi- och miljösystemstudier av andra specifika biogasanläggningar. Analysen innefattar direkta effekter som energian

Tobacco use and caries risk among adolescents - a longitudinal study in Sweden

Background: Smoking and the use of smokeless tobacco have a detrimental impact on general and oral health. The relationship to dental caries is however still unclear. As caries is a multi-factorial disease with clear life-style, socio-economic and socio-demographic gradients, the tobacco use may be a co-variable in this complex rather than a direct etiological factor. Our aim was to analyze the im

Low-dose prednisolone treatment of early rheumatoid arthritis and late cardiovascular outcome and survival: 10-year follow-up of a 2-year randomised trial

Objective To examine the long-term effects of early low-dose prednisolone use in patients with rheumatoid arthritis (RA) on cardiovascular (CV) morbidity and mortality. Design Retrieval of data from a 2-year open randomised trial comparing prednisolone 7.5mg/day in addition to disease-modifying antirheumatic drugs (DMARDs) with DMARD therapy alone. Participants were followed for 10years since incl

Path Tracking with Obstacle Avoidance for Pseudo-Omnidirectional Mobile Robots Using Convex Optimization

We consider the problem of trajectory generation for time-optimal path tracking for the class of pseudo-omnidirectional mobile robots. An Euler-Lagrange model of the robot dynamics is derived, and by writing it on special form a convex reformulation of the path-tracking problem can be utilized. This enables the use and regeneration of time-optimal trajectories during runtime. The proposed approach

Fetal loss and maternal serum levels of 2,2 ',4,4 ',5,5 '-hexachlorbiphenyl (CB-153) and 1,1-dichloro-2,2-bis(p-chlorophenyl)ethylene (p,p '-DDE) exposure: a cohort study in Greenland and two European populations

Background: In the present study, the aim is to examine the risk of fetal loss related to environmental 2,2',4,4',5,5'-hexachlorobiphenyl (CB-153) or 1,1-dichloro-2,2-bis(p-chlorophenyl)ethylene (p,p'-DDE) exposure. Methods: We related LC/MS/MS measurements of CB-153 and p, p'-DDE in serum samples to interview-data on previous fetal loss in populations of pregnant women from Poland, Ukraine and Gr
