The microfilaments in the acinar cell of the exocrine pancreas are essentially located in the apical part of the cell: thin microfilaments (50 A), cytochalasin B (CB)-sensitive, form the axis of the microvilli and a network lying beneath the apical membrane; thicker filaments (100 A), at least partly CB-insensitive, form bundles parallel to the plasma cell(More)
The critical role for ADP in arterial thrombogenesis was established by the clinical success of P2Y12 antagonists, currently used at doses that block 40-50% of the P2Y12 on platelets. This study was designed to determine the role of P2Y12 in platelet thrombosis and how its complete absence affects the thrombotic process. P2Y12-null mice were generated by a(More)
BACKGROUND This study was designed to determine whether (1) P2Y12 antagonism synergizes with other antithrombotics and (2) anticoagulants (thrombin inhibitors) affect the antithrombotic activity elicited by P2Y12 antagonism. METHODS AND RESULTS Thrombosis was achieved by perfusion of human and murine blood through type III collagen-coated capillaries at(More)
The relationship between asthma and gastro-oesophageal reflux (GER) is controversial. In an allergy department, GER prevalence was evaluated in asthmatics, with a view to judging the potential influence of GER on asthma. One hundred and five asthmatics were recruited and co-investigated for GER and lung function. Descriptive analysis was performed, patients(More)
The gastric antisecretory effects of oxmetidine, a new H2-receptor antagonist, have been studied in 33 healthy subjects. The relative potency of oxmetidine compared with that of cimetidine depended on the route of administration and the experimental conditions. Oxmetidine intravenously infused was approximately four times as potent as cimetidine, weight for(More)
Forty-three cases of peripheral neuropathy (PN) have been reported in the literature with a proven mitochondria (mt) DNA mutation, and 21 had a peripheral nerve biopsy (PNB). We studied 8 patients, 1 of whom had severe sensory PN, 3 mild PN, and 4 subclinical PN. Nerve biopsy was performed in every case; all patients showed axonal degeneration and 4 showed(More)
Airway inflammation is a major component of asthma. Food intake of N-3 fatty acids (FA) is associated with a low incidence of inflammatory diseases, such as asthma. We treated 12 asthmatic patients with FA and report the positive results of this 1-year double-blind study. A positive effect on forced expiratory volume in 1 s was observed after the 9 month of(More)
Controlled studies of nonsteroidal antiinflammatory drugs (NSAIDs) for the management of migraine attacks or for the prophylactic long-term treatment of migraine are reviewed herein. A large number of NSAIDs have been tested against a placebo or reference drug, including aspirin, indomethacin, mefenamic acid, tolfenamic acid, flufenamic acid, ibuprofen,(More)
