Six patients with Cushing's disease and a radiologically normal sella turcica have been treated by transsphenoidal hypophysectomy. Microadenomas were found and removed in five. One patient was in complete remission by 2 months and three by 6 months post-operatively. Two of the remaining patients (one with and the other without a surgically demonstrable(More)
Leukocytes play a primary role in vascular inflammation, and thus an understanding of the pathways involved in the activation of these cells and means to inhibit their consequent adhesion to the vessel wall is of significant interest. This study aimed to determine whether statins have a direct effect upon neutrophil adhesive properties under inflammatory(More)
Intravascular hemolysis, or the destruction of red blood cells in the circulation, can occur in numerous diseases, including the acquired hemolytic anemias, sickle cell disease and β-thalassemia, as well as during some transfusion reactions, preeclampsia and infections, such as those caused by malaria or Clostridium perfringens. Hemolysis results in the(More)
The effects of prolonged treatment with glyclazide [methyl-4-fenyl sulfonyl-1(perhydrocyclopenta(c) pyrrolyl-2)-3 urea] on blood glucose and plasma insulin responses to meals was studied in 8 obese patients with maturity-onset diabetes. Blood sampling was done 1 hr after meals for 2 consecutive days, on days 10 and 90 of therapy. Lower blood glucose curves(More)
Hydroxyurea (HU), or hydroxycarbamide, is used for the treatment of some myeloproliferative and neoplastic diseases, and is currently the only drug approved by the FDA for use in sickle cell disease (SCD). Despite the relative success of HU therapy for SCD, a genetic disorder of the hemoglobin β chain that results in red-cell sickling, hemolysis, vascular(More)
Although essential for inflammatory responses, leukocyte recruitment to blood vessel walls in response to inflammatory stimuli, such as TNF-α, can contribute to vascular occlusion in inflammatory diseases, including atherosclerosis. We aimed to further characterize the mechanisms by which TNF stimulates adhesive and morphologic alterations in neutrophils.(More)
Enterocromaffin-like cells (ECL) are specialized endocrine gastric cells able to release histamine, which in turn controls gastric acid production by parietal cells. Helicobacter pylori infection and other conditions signal in the gastrointestinal tract via Toll-like receptors (TLRs) and modify gastric acid production, but there is no evidence of expression(More)
