A search has been performed for the Standard Model Higgs boson in the data sample collected with the ALEPH detector at LEP, at centre-of-mass energies up to 209 GeV. An excess of 3 σ beyond the background expectation is found, consistent with the production of the Higgs boson with a mass near 114 GeV/c 2. Much of this excess is seen in the four-jet(More)
Melanotic neuroectodermal tumor of infancy (MNTI) is a rare neoplasm that generally arises in the maxilla during the first year of life. Involvement of bones of the cranial vault or brain is extremely rare. We describe a 7-month-old black female who presented after falling out of bed onto a concrete floor. Subsequently, she developed an anterior frontal(More)
Copper deficiency adversely affects the extracellular matrix of the arterial wall, leading to cardiovascular lesions. To study the lesions resulting from copper deficiency, the composition of proteoglycans from aortas of copper-deficient rats was compared with proteoglycans of aortas from copper-supplemented rats. Copper deficiency in rats was verified by(More)
Proteoglycans from human atherosclerotic lesions and from uninvolved aortic intima were isolated and their composition was studied. The tissues were sequentially extracted by guanidine hydrochloride followed by hydrolysis of the tissue by elastase. Chondroitin sulfate/dermatan sulfate proteoglycans were predominant in guanidine hydrochloride extracts of the(More)
Heparin-like glycosaminoglycans (GAG) were isolated from commerical Vessel and their biologic properties studied. Vessel was found to be a mixture of chondroitin sulfates, dermatan sulfate and heparin-like GAG. Chondroitin sulfates and dermatan sulfate in Vessel were hydrolyzed by chondroitinase ABC and the residual Vessel was fractionated on a Dowex-1 Cl-(More)
Lymph nodes (mandibular, mesenteric, mediastinal, and subiliac; n = 68) and fecal (n = 68) and hide (n = 35) samples were collected from beef carcasses harvested in an abattoir in Mexico. Samples were analyzed for Salmonella, and presumptive colonies were subjected to latex agglutination. Of the isolates recovered, a subset of 91 was characterized by(More)
