A patient with maculopapular reactions to iopamidol needed to undergo angiography for a cerebral arteriovenous malformation. In vivo and in vitro tests were performed with ionic and nonionic contrast media, including iopamidol and iobitridol. All results were positive, demonstrating delayed hypersensitivity. The patient received 6-alpha-methylprednisolone(More)
We investigated the mechanisms that regulate the efficacy of agonists in the arginine-vasopressin (AVP)/oxytocin (OT) receptor system. In this paper, we present evidence that AVP, a full agonist of the vasopressin receptors, acts as a partial agonist on the oxytocin receptor. We also found that AVP becomes a full agonist when two aromatic residues of the(More)
We previously produced evidence that the human mammary-carcinoma cell line 8701-BC expresses several metalloproteinases (MMP-1, -2, -9, and -10) and their tissue inhibitors). In order to obtain a better understanding of the environmental control over gelatinolytic activities, we have tested the enzyme production of 8701-BC cells, at time intervals after(More)
Human breast and colon carcinoma tissues contain a form of collagen, not described before, composed of alpha 1 chains of similar size (approximately 100 kDa) but different charge. The three constitutive chains, separated by two-dimensional electrophoresis, are a unique acidic component, undetectable in other collagen types, with an apparent isoelectric(More)
Aromatic antiepileptic drugs (phenytoin, carbamazepine, oxcarbazepine, and phenobarbital) are frequently associated with cutaneous eruptions. A cell-mediated pathogenic mechanism has been demonstrated in most of such reactions on the basis of positive responses to patch tests and/or lymphocyte transformation tests. Therefore, such tests are useful tools for(More)
Brain-derived neurotrophic factor (BDNF) is a neurotrophin that influences neuronal plasticity throughout life. Emergence from a vegetative state (VS) after a traumatic brain injury (TBI) implies that the brain undergoes plastic changes. A common polymorphism in the BDNF gene--BDNF Val66Met (referred to herein as BDNF(Met))--impairs cognitive function in(More)
We have recently identified an oncofetal-laminin binding collagen (OF/LB) composed of three alpha chains, with the apparent molecular mass of about 100 kDa each, but bearing different pI. One of the chains appears markedly acidic in a bidimensional electrophoretic system, where the NEPHGE is used as first dimension separating gel, while the two more basic(More)
BACKGROUND A cell-mediated immunopathogenic mechanism has been demonstrated in only a few cases of cutaneous reactions to systemically administered cephalosporins. OBJECTIVE The aim was to investigate the pathogenic mechanism of a maculopapular rash experienced by a subject during cefazolin therapy. METHODS AND RESULTS Prick, intradermal, and patch(More)
