Propositional reasoning is the ability to draw conclusions on the basis of sentence connectives such as and, if, or, and not. A psychological theory of prepositional reasoning explains the mental operations that underlie this ability. The ANDS (A Natural Deduction System) model, described in the following pages, is one such theory that makes explicit(More)
PURPOSE OF THE STUDY The aim of this study was to present the results of treatment of deep chondral defects of the patella by transplantation of a solid chondral graft formed by autologous cultured chondrocytes. MATERIAL AND METHODS Indications for autologous chondrocyte implantation most frequently included acute trauma to the knee, particularly the(More)
PURPOSE OF THE STUDY The authors present the results of surgical treatment of talar dome cartilage defects. They used the transplantation of autologous cultured chondrocytes in the form of a solid chondral graft. MATERIAL AND METHODS Patients with chondral lesions categorized as grades II to IV by the Anderson classification or as grades II to IV by the(More)
1. In this investigation the NO production rate is quantified in the pig during normotensive endotoxin-induced shock with increased cardiac output and during subsequent treatment with the NO synthase inhibitor N omega-monomethy-L-arginine (L-NMMA). NO production rate was derived from the plasma isotope-enrichment of 15N-labelled nitrate (15NO3-). 2. Three(More)
OBJECTIVES To compare the effects of norepinephrine (NOR) and the nonselective nitric oxide synthase inhibitor, N(G)-monomethyl-L-arginine (L-NMMA), on intestinal blood flow, oxygen exchange, and energy metabolism over 24 hrs of hyperdynamic, normotensive porcine endotoxic shock. DESIGN Prospective, randomized, experimental study with repeated measures.(More)
PURPOSE OF THE STUDY The treatment of deep chondral defects is one of the key issues in current orthopedics and traumatology. We developed a new technique that greatly improved the outcome of treatment in young active patients. The method is based on transplantation of in vitro cultured autologous chondrocytes carried on the fibrin glue Tissucol. MATERIAL(More)
The paper summarizes the experience with the application of cultured epidermal allografts in the treatment of deep dermal burns. In a series of patients, including 10 adults and 32 children this method allowed to attain an epithelialization in 90% of deep dermal burns. The advantages of this therapeutic method consist particularly in the early(More)
The local oxygen supply to the skin immediately before and after withdrawal of blood was appraised in 18 healthy test subjects by measuring the intracapillary hemoglobin oxygenation (HbO2). The investigation was carried out with the Erlanger Microlightguide Photometer (EMPHO). EMPHO measurements are based on the registration of tissue remission spectra from(More)
Two cases of subcutaneous dirofilariasis acquired in Ontario and Vermont are reported. The parasites in these and eight cases previously reported from the northern United States and Canada are classified as resembling Dirofilaria ursi, a primarily subcutaneous parasite of bears, or D. subdermata of porcupines, in the same region. A distinguishing(More)
We compared the effects of norepinephrine (NOR; n = 11) and the nonselective nitric oxide synthase inhibitor Nomega-monomethyl-L-arginine (L-NMMA; n = 11) on hepatic blood flow (Q liv), O2 exchange, and energy metabolism over 24 h of hyperdynamic, normotensive porcine endotoxic shock. Endotoxin (ETX; n = 8) caused a continuous fall in mean arterial pressure(More)
