Wires with Quantum Memory (2008)
Chryssomalakos, C., Hernandez, H., Gelbwaser-Klimovsky, D., Okon, E.
We show that quantum particles constrained to move along curves undergoing cyclic deformations acquire, in general, geometric phases. We treat explicitly an example, involving particular deformations...
Generalized Quantum Relativistic Kinematics: a Stability Point of View (2004)
We apply Lie algebra deformation theory to the problem of identifying the stable form of the quantum relativistic kinematical algebra. As a warm up, given Galileo's conception of spacetime as input,...
Linear Form of 3-scale Relativity Algebra and the Relevance of Stability (2004)
We show that the algebra of the recently proposed Triply Special Relativity can be brought to a linear (ie, Lie) form by a correct identification of its generators. The resulting Lie algebra is the...
Aspergillus quadrilineatus, a new causative agent of fungal sinusitis.
Polacheck, I, Nagler, A, Okon, E, Drakos, P, Plaskowitz, J, Kwon-Chung, K J
Aspergillus quadrilineatus was found to be the etiologic agent of pansinusitis in a patient suffering from acute nonlymphoblastic leukemia and who had undergone allogeneic bone marrow...
Eliakim, R, Gilead, L, Ligumsky, M, Okon, E, Rachmilewitz, D, Razin, E
An association between the release of histamine and chondroitin sulfate E proteoglycan (PG) was demonstrated in human colonic mucosa (HCM). Colonic biopsy samples incorporated [35S]sulfate (2.7 X...
Peled-Kamar, M, Lotem, J, Okon, E, Sachs, L, Groner, Y
The copper-zinc superoxide dismutase (CuZnSOD) gene resides on chromosome 21 and is overexpressed in Down syndrome (DS) patients. Transgenic CuZnSOD mice with elevated levels of CuZnSOD were used to...

Human gastric mucosal mast cells are chondroitin sulphate E-containing mast cells.
Gilead, L, Livni, N, Eliakim, R, Ligumsky, M, Fich, A, Okon, E, ...
Our recent identification of chondroitin sulphate E-containing mast cells (E-MC) in the human colonic mucosa is extended here to the human gastric mucosa by using a combination of both biochemical...
Ben-Chetrit, E, Flusser, D, Okon, E, Ackerman, Z, Rubinow, A
A patient with seropositive rheumatoid arthritis and a carrier of hepatitis B surface antigen developed angiofollicular hyperplasia (multicentric Castleman's disease). The hepatitis B virus and the...
Mixed connective tissue disease presenting as a left sided pleural effusion.
Ilan, Y, Ben-Yehuda, A, Okon, E, Breuer, R
Mixed connective tissue disease (MCTD) usually occurs in women aged 13-50 years. Pleural effusion is rarely the presenting feature of this disease. The case is reported here of a male patient with...
Octreotide effectively decreases mucosal damage in experimental colitis.
Eliakim, R, Karmeli, F, Okon, E, Rachmilewitz, D
The effect of octreotide, a synthetic analogue of somatostatin, on the modulation of the acetic acid model of experimental colitis was examined. Colitis was induced by intracolonic administration of...
A novel antiulcerogenic stable radical prevents gastric mucosal lesions in rats.
Rachmilewitz, D, Karmeli, F, Okon, E, Samuni, A
The pathogenesis of gastric mucosal injury is still poorly understood. Recent reports implicate redox active metals and reactive oxygen species as mediators of gastric damage induced by ethanol or...
Ketotifen effectively prevents mucosal damage in experimental colitis.
Eliakim, R, Karmeli, F, Okon, E, Rachmilewitz, D
The effects of ketotifen, a 'mast cell stabiliser,' on two models of experimental colitis were examined. The inflammatory response elicited by either trinitrobenzene sulphonic acid or acetic acid...
Experimental colitis is ameliorated by inhibition of nitric oxide synthase activity.
Rachmilewitz, D, Karmeli, F, Okon, E, Bursztyn, M
Enhanced nitric oxide (NO) generation by stimulated NO synthase (NOS) activity may, through its oxidative metabolism contribute to tissue injury in experimental colitis. In this study the possible...
A stable nitroxide radical effectively decreases mucosal damage in experimental colitis.
Karmeli, F, Eliakim, R, Okon, E, Samuni, A, Rachmilewitz, D
TEMPOL, a cyclic nitroxide stable radical blocks biological damage by breaking chain reactions through termination reaction with free radicals, and by inhibiting the catalytic effect of transition...
Sulphydryl blocker induced gastric damage is ameliorated by scavenging of free radicals.
Karmeli, F, Okon, E, Rachmilewitz, D
BACKGROUND: Sulphydryl compounds and nitric oxide are essential in maintaining gastric mucosal integrity. AIMS: To characterise the gastric damage induced by a sulphydryl blocker, to evaluate the...

Malignant fibrous histiocytoma of the conjunctiva.
Pe'er, J., Levinger, S., Ilsar, M., Climenhaga, H., Okon, E.
Malignant fibrous histiocytoma (MFH) of the conjunctiva is an extremely rare tumour, and only three previous cases have been reported. We describe two patients with MFH of the conjunctiva: a...
