Two methods for volume flow calculation from images of methane leakages to the atmosphere are presented. The images contain calibrated gas concentration x path length pixel information, and are processed with a block matching method and a theoretical velocity field method. Results from known methane flow in two laboratory setups and one unknown real leakage from a gas processing plant are compared
Recent technological advances open exciting avenues for improving the understanding of mechanisms in a broad range of epilepsies. This chapter focuses on the development of optogenetics and on-demand technologies for the study of epilepsy and the control of seizures. Optogenetics is a technique which, through cell-type selective expression of light-sensitive proteins called opsins, allows temporal
BACKGROUND: Molecular evolution of carbohydrate binding modules (CBM) is a new approach for the generation of glycan-specific molecular probes. To date, the possibility of performing affinity maturation on CBM has not been investigated. In this study we show that binding characteristics such as affinity can be improved for CBM generated from the CBM4-2 scaffold by using random mutagenesis in combi
Popular Abstract in Swedish Diabetes är en folksjukdom där c:a 350000 människor i Sverige är drabbade. Fotsår är en vanlig komplikation vid diabetes, och sådana svårläkta sår leder till c:a 700 diabetesrelaterade amputationer årligen. Såväl såren som amputationssituationen orsakar funktionshinder, smärta, sociala bekymmer samt psykisk stress för dem som drabbas. Att utveckla nya och förbättrade beDiabetes wounds result in significant morbidity, prolonged hospitalization and huge health care expenses. As of yet, no optimal animal models of diabetic wound healing exist to study potential beneficial therapies. Porcine wound healing is very similar to human wound healing. We stipulated that by inducing diabetes in yorkshire pigs, wound healing would be delayed and exhibit abnormalities similar
Background: Studies have shown that lifestyle interventions are effective in preventing or delaying the onset of type 2 diabetes in high-risk patients. However, research on the effectiveness of lifestyle interventions in high-risk immigrant populations with different cultural and socioeconomic backgrounds is scarce. The aim was to design a culturally adapted lifestyle intervention for an immigrant
Double-stranded DNA in many bacterial viruses (phage) is strongly confined, which results in internal genome pressures of tens of atmospheres. This pressure is strongly dependent on local ion concentration and distribution within the viral capsid. Here, we have used electron energy loss spectroscopy (EELS), energy-filtered TEM (EFTEM) and X-ray energy dispersive spectroscopy to provide such chemic
The myeloid translocation gene 16 product MTG16 is found in multiple transcription factor-containing complexes as a regulator of gene expression implicated in development and tumorigenesis. A stable Tet-On system for doxycycline-dependent expression of MTG16 was established in B-lymphoblastoid Raji cells to unravel its molecular functions in transformed cells. A noticeable finding was that express
Objective: To evaluate the results of the expanded National Venous Screening Program (NVSP) as administered by the American Venous Forum. Methods. Eighty-three physicians across 40 states participated in screening Americans for venous disease. The NVSP instrument included demographics, venous thromboembolism (VTE) risk assessment, quality-of-life (QOL) assessment, duplex ultrasound scan for reflux
Detailed analyses of the biometrics of white-spotted bluethroats captured in the Iberian Peninsula and sub-Saharan Africa show that previous criteria for diagnosing subspecies are inadequate. This deficiency seems to result from feather wear during the breeding period and so new criteria are proposed for the migratory and wintering periods. Foreign recoveries in Portugal indicate that the new crit
Aim: To evaluate the efficacy of various echocardiographic markers in predicting a patent ductus arteriosus (PDA) in need of treatment. Methods: Forty-five preterm infants with a mean (SD) gestational age of 27.7 (1.9) weeks underwent echocardiography at a postnatal age of 24 +/- 6 and 72 +/- 6 h. Four echocardiographic markers were studied: ductus diameter, ductal flow Doppler curves, the left at
The aim was to assess long-term cognitive performance after substantial recovery from work-stress-related exhaustion, in relation to subjective cognitive complaints and return to active work. In total, 54 patients previously diagnosed with work-stress-related exhaustion participated in a neuropsychological examination similar to 2 years after initial sick leave. Most participants were substantiall
ABR-215757 (5757) is a quinoline-3-carboxamide (Q-compound) currently in clinical development for systemic sclerosis. Q-compounds have shown efficacy in several different models of autoimmune diseases such as experimental autoimmune encephalomyelitis (EAE) and collagen induced arthritis. However, the mechanism of action is still poorly understood. In this thesis we have tried to find the mechanism
There is increasing theoretical and empirical evidence that genetic compatibility among partners is an important determinant of fertilization success and offspring viability. In amphibians, females often actively choose partners from among a variety of males and polyandry is common. Genetic compatibility among partners may therefore be an important determinant of fertilization success and offsprin
