Apart from some misunderstandings of this summer, recent developments have led to considerable progress in this controversial but challenging field. Intermittency is now established as an effect in at least two dimensions, where it has turned out to be stronger and cleaner than in one. The effect is strongest in Ih and e+e~ collisions. In hh collisions, where the energy range covered is the lar...
Cyclophosphamide (CY) is a clinically used cytotoxic agent that is effective in a wide range of tumor types including breast and small cell lung cancers. However, by far not all patients benefit from CY therapy. We used patient tumor explants grown in nude mice as an experimental model system to identify a gene signature that, based on a tumor's gene expression profile, predicts its CY response...
Anthocyanins have multiple biological activities of benefit to human health. While a few studies have been conducted to evaluate the bioavailability of anthocyanins, the mechanisms of their absorption mechanism remain ill-defined. In the present study, we investigated the absorption mechanism of cyanidin-3-O-β-glucoside (Cy-3-G) in human intestinal epithelial (Caco-2) cells. Cy-3-G transport wa...
CD4(+)CD25(+)Foxp3(+) regulatory T (Treg) cells have been shown to play important roles in mediating cancer development. Although cyclophosphamide (CY) has shown promise as a drug to selectively target Treg cells with low-dose in vivo, the underlying molecular mechanism remains unclear. In this report, we provide evidence that ATP, the energy molecule and signal element, accounts for the select...
High-dose cyclophosphamide (Cy) has been promoted as curative therapy for severe aplastic anemia (SAA). However, our randomized trial comparing antithymocyte globulin (ATG) and Cy was terminated early because of excess morbidity/early mortality in the Cy arm. We now report analysis of secondary endpoints at a median of 38 months. Relapse occurred in 6 (46%) of 13 responders in the ATG arm versu...
CYSTS of the uveal tract have been classified clinically as congenital, parasitic, exudative or degenerative, traumatic implantation, and spontaneous or idiopathic (Duke-Elder, 1940). There is considerable overlap between the last two groups and many cases which one suspects of being traumatic in origin give no history of injury. The tissue forming the cyst in traumatic cases has been implanted...
آرتریت روماتوئید rheumatoid arthritis,(ra) یک بیماری خود ایمن است که یکی از معیارهای تشخیصی آن وجود فاکتور روماتوئید ( rheumatoid factor,rf ) در سرم بیماران می باشد. مطالعات نشان داده اند که بین بیماران آرتریت روماتوئید rf+ و rf- از نظر تظاهرات بافت شناسی ( histologic ) اختلافاتی وجود دارد. در این مطالعه میزان (crp) c-reactive protein و ایزوتیپهای iga rf و igm rf در 45 بیمار مبتلا به ra مورد سن...
Results from retrospective studies on the relationship between cytochrome P450 (P450) 2B6 (CYP2B6) genotype and cyclophosphamide (CY) efficacy and toxicity in adult cancer patients have been conflicting. We evaluated this relationship in children, who have faster CY clearance and receive different CY-based regimens than adults. These factors may influence the P450s metabolizing CY to 4-hydroxyc...
PURPOSE Granulocyte-macrophage colony-stimulating factor (GM-CSF) -secreting tumor vaccines have demonstrated bioactivity but may be limited by disease burdens and immune tolerance. We tested the hypothesis that cyclophosphamide (CY) and doxorubicin (DOX) can enhance vaccine-induced immunity in patients with breast cancer. PATIENTS AND METHODS We conducted a 3 x 3 factorial (response surface)...
In a murine bone-marrow transplant (BMT) model designed to determine risk factors for lung dysfunction in irradiated mice, we reported that cyclophosphamide (Cy)-induced injury and lethality depended on the infusion of donor spleen T cells. In the study reported here, we hypothesized that alveolar macrophage (AM)-derived reactive oxygen/nitrogen species are associated with lung dysfunction caus...
