Using two-pulse photon echo excitation a strong resonance in the measured homogeneous dephasing time as a function of magnetic field is observed in the H-3(4)-D-1(2) transition of Pr3+:YAlO3. The resonance could only be observed at low excitation energies since it otherwise was masked by excitation intensity dependent extra dephasing processes in the crystal. Thus intensity dependent dephasing pro

The serine protease tissue-type plasminogen activator (t-PA) is involved in both vital physiological brain processes, such as synaptic plasticity, and pathophysiological conditions, such as neurodegeneration and ischemic stroke. Recent data suggest that epigenetic mechanisms play an important role in the regulation of t-PA in human endothelial cells. However, there are limited data on epigenetic r

Objective. To study the prevalence of fatigue and daytime sleepiness in primary SS (pSS) and analyse predicting sleep disturbing factors and other potential determinants of fatigue and sleepiness. Method. Seventy-two consecutive pSS patients and 59 age-matched healthy controls were compared. Assessment instruments were profile of fatigue (ProF), visual analogue scale fatigue, Epworth Sleepiness Sc

Abstract Background. Complementary and alternative medicine (CAM) use is common among breast cancer patients. Several CAM therapies may have negative side effects or interact with conventional therapies. We studied biologically based CAM use with and without vitamins/minerals in relation to patient and tumor characteristics as well as treatment in an ongoing prospective cohort of 855 primary breas

Benchmarking is an effective tool to compare the performance of full-scale wastewater treatment plant operation. In this study, 29 wastewater treatment plants from eight countries were surveyed with the aim of developing some key performance indicators, which may be used for benchmarking purposes. The level of utilisation of instrumentation, control and automation (ICA) has also been measured. The

The aim of this study is to assess mortality risk and the excess of risk in patients with diabetes. Patients were 15-34 years old at diagnosis of diabetes mellitus (n = 879) in 1992 and 1993 in this national cohort from Sweden. Healthy controls were matched for gender and birth on the same day as the index cases (n = 837). The civic registration number was used to link patients and controls to the

De arkeologiska utgrävningarna är den historiska forskningsinstitution som är starkast reglerat i lag, till och med fastare än historieämnets plats i skolundervisningen. Om en exploatör vill utnyttja mark där fornminne finns är det ett ovillkorat krav att platsen ska grävas ut och resultaten dokumenteras. I tider av expansion för bebyggelse och infrastruktur utvecklas därför institutionerna kring

Cerebral malaria (CM) is a life-threatening complication of Plasmodium falciparum infection. The pathogenesis of CM is complex. Cerebral metabolic dysfunction is implicated in CM, which may be caused by both an impaired cerebral microcirculation and a dysregulated inflammatory response affecting cellular respiration of mitochondria. Recombinant human erythropoietin (rhEPO) is a promising new thera
