A roller coaster ride comes to an end. Magnets on the train induce eddy currents in the braking fins, giving a smooth rise in braking force as the remaining kinetic energy is absorbed by the brakes and converted to thermal energy. In this paper an IR camera was used to monitor the temperature of the first braking fin, before, during and after the passage of a train. In addition, the resulting acce
Osteoporosis is common in the elderly, and it is associated with lifetime exposure to endogenous hormones and vitamin D intake, both of which are associated with cancer development. The association of osteoporosis with subsequent cancer has not been established, and hence we examined here the overall and site-specific cancer risks among Swedish individuals after hospitalization for osteoporosis. P
Previous research has shown -125 mmHg to be the optimal negative pressure for creating an environment that promotes wound healing, and this has therefore been adopted as a standard pressure for patients with deep sternal wound infection. However, it has not yet been clearly shown that -125 mmHg is the optimal pressure from a haemodynamic point of view. Furthermore, there have been reports of cardi
Summary Background, objectives and methods: An accurate, sensitive and precise assay for reliable determination of the ristocetin cofactor activity of von Willebrand factor (VWF:RCo) in plasma and von Willebrand Factor (VWF)-containing concentrates has been evaluated. The assay is based on a commercially available automated protocol with modifications including a combination of adding additional r
PURPOSE: Endothelin (ET)-1 has been implicated in the atherosclerotic process and during inflammation. Similarity in the development process of giant cell arteritis (GCA) and atherosclerosis exists. Several ET receptor antagonists have been developed, principally to target cardiovascular disease states. High doses of corticosteroids currently are used in the treatment of GCA, whereas other treatme
PURPOSE: Randomized multiple myeloma (MM) studies show improved response rates and better progression-free survival for newer therapies. However, a less pronounced effect has been found for overall survival (OS). Using population-based data including detailed treatment information for individual patients, we assessed survival patterns for all patients diagnosed with MM in Malmö, Sweden from 1950 t
The fifth harmonic of a 60-fs 10-Hz terawatt titanium:sapphire laser generated in Xe gas is used to ionize Xe and Kr atoms by nonresonant two-photon absorption and At atoms through a quasiresonant three-photon process. At relatively low harmonic yields, the variation of the number of Kr and Xe ions with the number of harmonic photons is quadratic. At high harmonic yields, it deviates from a quadra
The nonrandom behavior of the outputs of a random S-box can be exploited when constructing distinguishers for cryptographic primitives. Different methods of constructing samples from the outputs have been used in the literature. However, it has been unclear exactly how these methods differ and which method is optimal. We analyze four different sampling techniques. We prove that two of these sampli
We compared the incidence of cancer among Turkish, Chilean, and North African (NA) first-generation immigrants with residents in their countries of origin and native Swedes. The Swedish Family-Cancer Database was used to calculate age-standardized incidence rates. We compared the age-standardized incidence rates for immigrants with those in the Cancer Incidence in Five Continents report. All-cance
Phthalates, a class of chemicals used as plasticizers, are economically important due to several industrial applications. Di-(2-ethylhexyl) phthalate (DEHP) is the most commonly used phthalate plasticizer, and it has been described as a potent antiandrogen in males. In this study, lactating dams were exposed via oral gavage to corn oil (vehicle) and DEHP (1, 10, and 100 mg/kg body weight) from pos
Activation of microglia and inflammation-mediated neurotoxicity are suggested to play a decisive role in the pathogenesis of several neurodegenerative disorders. Activated microglia release pro-inflammatory factors that may be neurotoxic. Here we show that the orderly activation of caspase-8 and caspase-3/7, known executioners of apoptotic cell death, regulate microglia activation through a protei
Abstract Purpose: To explore the early reactions of the retinal Müller glia in response to retinal insult prior to gliotic remodeling and the sustained upregulation of intermediate filament glial fibrillary acidic protein (GFAP), which has traditionally been considered the most sensitive early indicator of reactive gliosis. Methods: To study pre-gliotic events, we used a model of adult rat retinal

There is ample evidence for intra-patient evolution of the human immunodeficiency virus type 1 (HIV-1) biological phenotype during the pathogenic process. Evolution often involves switch of coreceptor use from CCR5 to CXCR4, but change to more flexible use of CCR5 occurs over time even in patients with maintained CCR5 use. The increasing use of entry inhibitors in the clinic, often specific for on
