question:
The purpose of the present study was to evaluate the detection rate of genomic aberrations in haematological malignancies using oligobased array-CGH (oaCGH) analysis in combination with karyotyping and fluorescence in situ hybridization (FISH) analyses, and its feasibility in a clinical pragmatic approach.', 'The 4x180K Cancer Cytochip array was applied in 96 patients with various haematological malignancies in a prospective setting and in 41 acute myeloid leukemia (AML) patients retrospectively.', 'Combined use of oaCGH analysis and karyotyping improved the overall detection rate in comparison to karyotyping-alone and vice versa. In cases with normal karyotypes oaCGH analysis detected genomic aberrations in 66% (39/60) of cases. In the group of simple karyotypes oaCGH analysis extended karyotypic findings in 39% (12/31) while oaCGH analysis extended the karyotypic findings in 89% (39/44) of cases with complex karyotypes. In 7% (5/75) of cases oaCGH analysis failed in detecting the observed abnormalities by karyotyping.
answer:
Does oligo-based High-resolution aCGH Analysis enhance Routine Cytogenetic Diagnostics in Haematological Malignancies?


question:
The C57BL/6J-Min/+ (Min/+) mouse bears a germline mutation in Apc and is therefore a model for familial adenomatous polyposis and sporadic colorectal cancer. Min/+ intestinal mucosa exhibits a marked tendency for spontaneous adenoma formation. Curcumin is a phenolic antioxidant known for its antitumor and immune modulatory functions in vitro. Curcumin prevents adenoma formation in Min/+ mice, through a mechanism that may be related to its immunomodulatory properties.', 'To study the relationship between intestinal immunity and curcumin-induced antitumor response, we used immunohistochemistry to characterize the effect of curcumin treatment on resident intestinal immune effector cells in Min/+ mice.
answer:
Is inhibition of intestinal tumors by curcumin associated with changes in the intestinal immune cell profile?


question:
To examine the inhibition of nitric oxide (NO) synthesis during ischemic preconditioning (IP) upon the induction of heat-shock protein 72 (HSP72) and the size-limiting effect of the second window of protection on infarction.', 'Rabbits were subjected to either 4 cycles of 5-min long coronary artery occlusion separated by 10 min of reperfusion, or a sham operation. During this procedure, we administered 10 mg/kg of N(G)-nitro-L-arginine methyl ester (L-NAME, an inhibitor of NO synthase) intravenously 5 min before IP followed by its continuous infusion (1.5 mg/kg/min). Twenty-four hours after IP or the sham operation, the hearts were rapidly excised for assay of HSP72 expression or were subjected to 30 min of coronary artery occlusion followed by 120 min of reperfusion, at which point infarct size (IS) was measured.', 'Twenty-four hours after IP or the sham operation, there was no difference in heart rate or mean arterial pressure between the groups. Immunoblotting revealed an increase in HSP72 protein levels in the IP group, which was blocked by L-NAME. IS in the IP rabbits was reduced compared with controls (29.8 +/- 3.7% vs. 50.8 +/- 4.3%, P < 0.01). IS in the IP rabbits was elevated as a result of L-NAME treatment (46.0 +/- 5.1%). Administration of L-arginine reversed the effects of L-NAME on the induction of HSP72 and IS (33.5 +/- 4.0%). The intravenous administration of S-nitroso-N-acetylpenicillamine (an NO donor, 15 microg/kg/min) over 20 min increased the induction of HSP72 and reduced IS (31.3 +/- 5.7%, P < 0.01 vs. control) 24 h later.
answer:

Does nitric oxide open second window of protection in ischemic preconditioning via induction of heat-shock protein 72?
