Randomized, split plot, double-blind, placebo controlled trial. Half of the wounds surface was applied daily with insulin and the other half with saline solution as placebo. Biopsy specimens of the two sides were obtained on days 0 and 14. Number of blood vessels will be evaluated as main outcome.
Angiogenesis increases in higher risk MDS patients and those with proliferative CMML. Angiogenesis is associated with increased risk of leukemic transformation and poorer prognoses. Low dose chemotherapy may have anti-angiogenic properties by targetting the genetically stable endothelial cells. Lenalidomide has been recently shown to be highly effective as monotherapy in low/low-intermediate risk MDS, particularly in the subgroup harboring a 5q- deletion. Lenalidomide has not been well studied in higher risk MDS although there are some reports of lenalidomide's efficacy in RAEB-T and AML. One potential mode of action of lenalidomide is inhibition of angiogenesis. The investigators hypothesize that by combining lenalidomide with low dose melphalan in higher risk MDS the investigators will more effectively block angiogenesis and achieve responses or hematologic improvement in MDS.
Fractalkine (FKN) is a chemoattractant and adhesion molecule for leukocytes. Angiogenic effect of FKN also has been reported. We investigate FKN-mediated angiogenesis in ocular angiogenic disorders.
Changes in major angiogenic proteins have been seen following initiation of tamoxifen and aromatase inhibitor therapy in women with breast cancer. One source of these proteins is the circulating platelet pool. The investigators hypothesize that in addition to their anti-platelet properties, agents such as aspirin can be used as targeted anti-angiogenesis therapy. The investigators will determine the influence of aspirin on the release of angiogenic proteins from platelets in 35 patients with breast cancer.
Purpose: L-[3-18F]-α-methyltyrosine (18F-FMT) is an amino-acid tracer for PET. We have conducted a clinicopathologic study to elucidate the correlation of angiogenesis with 18F-FMT and 18F-FDG uptake in the patients with non-small cell lung cancer (NSCLC). Method: Thirty-seven NSCLC patients were enrolled in this study, and a pair of PET study with 18F-FMT and 18F-FDG was performed. Uptake of PET tracers was evaluated with standardized uptake value. VEGF, CD31, CD34, LAT1 and Ki-67 labeling index of the resected tumors were analyzed by immunohistochemical staining, and correlated with the clinicopathologic variables and the uptake of PET tracers.
Diabetic foot ulcers are a major cause of morbidity and mortality, accounting for approximately two-thirds of all non-traumatic amputations performed in the United States. The cost of foot ulcers in diabetic patients averages almost $28,000 for the two years after diagnosis of the ulcer. Hyperbaric oxygen (HBO) serves as primary or adjunctive therapy for a diverse range of medical conditions. HBO also has been used as an adjunct to antibiotics, debridement, and revascularization in the therapy of chronic, nonhealing wounds associated with diabetes or non-diabetic vascular insufficiency. The aim of the study is to assess whether hyperoxia induced angiogenesis in diabetic patients with foot ulcers.
