In this paper, we discuss the construction of classifying spaces of fibre sequences in model categories of simplicial sheaves. One construction proceeds via Brown representability and provides a classification in the pointed model category. The second construction is given by the classifying space of the monoid of homotopy self-equivalences of a simplicial(More)
OBJECTIVE Activation and suppression of immune responses are crucial events during sepsis. Based on substantial new data, a complex picture of differential immune-enhancing and immunosuppressive actions of adrenocortical steroids is emerging. The adrenal androgen dehydroepiandrosterone and its precursor, dehydroepiandrosterone-sulfate, show a considerable(More)
A strictly anaerobic, dichloromethane-utilizing bacterium was isolated from a previously described dichloromethane-fermenting, two-component mixed culture. In a mineral medium with vitamins, the organism converted 5 mM dichloromethane within 7 days to formate plus acetate in a molar ratio of 2:1 and to biomass and traces of pyruvate. Of 50 potential(More)
In congenital myasthenic syndrome with DOK7 mutations ephedrine was reported to be beneficial in single patients. We carried out a small, open and prospective cohort study in eight European patients manifesting from birth to 12 years. Five patients showed limb-girdle and facial weakness, three a floppy infant syndrome with bulbar symptoms and/or respiratory(More)
IMPORTANCE The effectiveness of intravenous thrombolysis in acute ischemic stroke is time dependent. The effects are likely to be highest if the time from symptom onset to treatment is within 60 minutes, termed the golden hour. OBJECTIVE To determine the achievable rate of golden hour thrombolysis in prehospital care and its effect on outcome. DESIGN,(More)
IMPORTANCE Time to thrombolysis is crucial for outcome in acute ischemic stroke. OBJECTIVE To determine if starting thrombolysis in a specialized ambulance reduces delays. DESIGN, SETTING, AND PARTICIPANTS In the Prehospital Acute Neurological Treatment and Optimization of Medical care in Stroke Study (PHANTOM-S), conducted in Berlin, Germany, we(More)
OBJECTIVE Beneficial effects of IV tissue plasminogen activator (tPA) in acute ischemic stroke are strongly time-dependent. In the Pre-Hospital Acute Neurological Treatment and Optimization of Medical care in Stroke (PHANTOM-S) study, we undertook stroke treatment using a specialized ambulance, the stroke emergency mobile unit (STEMO), to shorten(More)
May 2, 2017 1765 CORRPONDENCE The effects of intravenous thrombolysis (IVT) in ischemic stroke are time dependent.1,2 Because of delays in conventional stroke workup, previous randomized IVT trials were unable to include patients with onset-to-treatment time (OTT) ≤60 minutes of symptom onset. With the invention of computed tomography–equipped mobile stroke(More)
