The effect of noradrenaline (NA) on mucociliary activity in the rabbit maxillary sinus was investigated in vivo by injecting it at increasing dosages (10(-11) to 10(-4) mol/kg) into the maxillary artery, the mucociliary response being recorded photoelectrically. NA increased mucociliary activity at a dosage of 10(-5) mol/kg, the maximal increase being 16.1 +/- 2.6%. The NA-induced stimulation of m
Över två generationer har Indien och Kina förändrats från slumrande jättar med stora problem till snabbt uppvaknande kontinenter med långtgående anspråk på en plats i världspolitiken och den globala ekonomin. Deras snabbt skiftande situation har naturligtvis förändrat våra bilder dramatiskt och med dem vad vi tror oss veta om utvecklingens drivkrafter i den moderna världen. Frågan är dock om vi ve
Moderate hyperhomocysteinemia, an independent cardiovascular risk factor, has been reported in renal transplant recipients. In the present study, plasma concentrations of total homocysteine were significantly increased in 120 renal transplant recipients as compared with 60 healthy controls (19.0 +/- 6.9 vs. 11.6 +/- 2.8 mumol/L, P < 0.0001) and as compared with 53 patients without a transplant but
In laser-assisted combustion diagnostics it is a recurring task to predict molecular transitions whose signal strength depends only weakly on variations in temperature. The signal strength is proportional to the Boltzmann fraction of the level probed and the amplitude of the absorption line profile. In the past investigations have been presented in which this task was attack by detailed numerical
Useful clinical tests are lacking for the controversial entity "cervical vertigo". In earlier studies patients assumed to suffer from cervical vertigo or dizziness manifested disturbed postural control as compared to healthy subjects, but were hard to distinguish from patients with other balance disorders. Using posturography in which stance was perturbed by a vibratory stimulus applied towards th
Background The aim of the Nordic Diltiazem (NORDIL) Study was to compare patients with essential hypertension receiving calcium-antagonist-based treatment with diltiazem and similar patients receiving conventional diuretic/beta-blocker-based treatment, with respect to cardiovascular morbidity and mortality. Objective To assess the influence of age, sex, severity of hypertension and heart rate on t
An entity is described which is characterized by low back pain and increased radionuclide uptake in the sacrum at bone scintigraphy in postmenopausal women having received radiotherapy towards the pelvis because of gynaecological malignancy. The findings stimulate bone metastases, but are in all likelihood caused by insufficiency fractures of the sacrum promoted by bone weakness induced by postmen
We have developed high-throughput tests for the detection of the insulin gene region SNPs -23HphI and -2221MspI. The potential of these markers to enhance the efficiency of type I diabetes risk screening was then evaluated by analyzing them in Finnish and Swedish populations. Blood spots on filter paper were analyzed using PCR followed by sequence- specific hybridization and time-resolved fluorome
Naturgas är ett rent bränsle som endast innehåller små mängder föroreningar, [1]. Jämfört med kol är föekomsten av föroreningar i naturgas vanligen 1000 ggr mindre. Man får därför inga problem med svaveldioxid, tungmetaller, klorerade föroreningar etc i avgaserna. Vid normal drift bildas mycket lite sot och de huvudsakliga förbränningsprodukterna är vatten och koldioxid. Vatten ställer normalt int
OBJECTIVE: To determine if the frequency of alpha 1AT deficiency (PiZ) is increased in patients with abdominal aortic aneurysm (AAA), and, to investigate whether aneurysmal stiffness and other clinical characteristics differ in AAA patients with and without alpha 1AT deficiency. METHODS: We identified alpha 1AT-deficient individuals by a monoclonal-antibody ELISA technique, in 102 consecutive pati
Biotechnological leaching has been proposed as a suitable method for extraction of vanadium from spent catalysts and oil ash. In the biological leaching process, the vanadium(V) can be reduced to vanadium(IV), which is a less toxic and more soluble form of the vanadium. The present investigation showed that Acidithiobacillus ferrooxidans efficiently reduced vanadium(V) in the form of vanadium pent
