BACKGROUND AND OBJECTIVES Chronic lymphocytic leukemia (CLL) is the most common leukemia in the western world. Despite several advances in therapeutic options, the disease remains incurable. Recently, it was repeatedly demonstrated that statins, competitive inhibitors of 3-hydroxy-3-methyl glutaryl coenzyme A (HMG-CoA) reductase, have antineoplastic(More)
Therapeutic ultrasound (ULS) and the resulting cavitation process has been shown to induce irreversible cell damage. In this study, we wanted to further investigate the mechanism of ULS-induced cell death and to determine whether apoptosis is involved. High intensity focused pulsed ULS sonication at a frequency of 750 KHz was delivered to HL-60, K562, U937,(More)
BACKGROUND Pregnant women with breast cancer present with a more advanced disease compared with non-pregnant women. Nevertheless, breast cancer metastasis to the placenta is rare. Trophoblast/tumor implantations share the same biochemical mediators, while only the first is stringently controlled. We hypothesized that the same mechanisms that affect/restrain(More)
Cellular interactions with microenvironmental components are critical in multiple myeloma (MM) and impede effective disease treatment. Membranal-embedded tetraspanins, associated with metastasis suppression, are underexpressed in MM. We aimed to investigate the consequences of CD81/CD82 tetraspanins over-expression in MM cell lines. CAG and RPMI 8226 were(More)
BACKGROUND Accumulating reports indicate that statins widely prescribed for hypercholesteromia have antineoplastic activity. We hypothesized that because statins inhibit farnesylation of Ras that is often mutated in multiple myeloma (MM), as well as the production of interleukin (IL)-6, a key cytokine in MM, they may have antiproliferative and/or(More)
Lupus anticoagulants are closely related to systemic lupus erythemathosus (SLE) and to thrombotic events. We describe a 12 year-old girl with a bilateral intramuscular haemorrhage of the gastrocnemius muscles as her main initial presentation of juvenile SLE. Laboratory work-up revealed lupus anticoagulant-hypoprothrombinaemia syndrome (LAHS) with very low(More)
OBJECTIVES This study sought to evaluate expression of adhesion molecules on neutrophils and monocytes throughout the acute phase of myocardial infarction. BACKGROUND Neutrophil and monocyte counts increase within days from onset of acute myocardial infarction. Because leukocytes are recruited to the involved myocardial region, we postulated that these(More)
The role of tetraspanins is undefined, despite their detection in diverse cell types and functions. This study addresses the characterization of tetraspanin expression levels in normal peripheral blood leukocytes (PBL) and in patients with bacterial infection. Membranal and cytoplasmic expression of CD9, CD53, CD63, CD81, CD82 and CD151 in(More)
Recent studies reported reduced immunity in athletes following exercise. Physical activity affects both cellular and humoral immune functions. Scant information exists on exercise-induced changes in the immune system among children. The purpose of the present study was to investigate the effect of aerobic exercise on several aspects of cellular and humoral(More)
Large (L) activated platelets exhibit greater aggregability and express more activated glycoprotein IIb-IIIa (GPIIb-IIIa) per cell and per unit surface area than small (S) activated platelets. We studied the binding of CD61 monoclonal antibody to GPIIb-IIIa on resting platelets and developed a new method for determining platelet surface area by flow(More)
