Extra-Virgin Olive Oil from Apulian Cultivars and Intestinal Inflammation.

Inflammatory bowel disease (IBD) is a multifactorial intestinal disorder characterized by chronic intestinal inflammation. The etiology of IBD is still unclear, although genetic, environmental and host factors have been associated to the disease. Extra-virgin olive oil (EVO) is a central component of the Mediterranean diet and it decreases chronic inflammation by interfering with arachidonic acid and NF-κB signaling pathways.

Platelet-Specific Deletion of Cyclooxygenase-1 Ameliorates Dextran Sulfate Sodium-Induced Colitis in Mice.

Inflammatory bowel disease (IBD) is associated with an increased risk for thromboembolism, platelet activation, and abnormalities in platelet number and size. In colitis, platelets can extravasate into the colonic interstitium. We generated a mouse with a specific deletion of cyclooxygenase (COX)-1 in megakaryocytes/platelets [(COX-1 conditional knockout (cKO)] to clarify the role of platelet activation in the development of inflammation and fibrosis in dextran sodium sulfate (DSS)-induced colitis.

Aspirin and Cancer.

The place of aspirin in primary prevention remains controversial, with North American and European organizations issuing contradictory treatment guidelines. More recently, the U.S.

Telelap Alf-X: a novel telesurgical system for the 21st century.

Objective: To introduce a new telesurgical concept and system, we describe the TELELAP Alf-X system and report the results of the preliminary laboratory experiments on dry lab skill exercises.

Methods: The TELELAP Alf-X system offers a novel approach to remotely operated 3-dimension endoscopy by adding haptic sensation, an eye-tracking system, and a high degree of configuration versatility. The Alf-X system consists of a remote control unit, manipulator arms, connection node, and reusable endoscopic instruments.

Short communication: proangiogenic hematopoietic cells in acute HIV infection.

Chronic HIV infection induces significant changes in the trafficking of circulating endothelial progenitor cells (EPCs). Specifically, it causes marked depletion of proangiogenic hematopoietic cells, the so-called colony-forming unit-endothelial cells (CFU-ECs). In this study we evaluated CFU-ECs in two subjects with acute HIV infection.

Effects of celecoxib on prostanoid biosynthesis and circulating angiogenesis proteins in familial adenomatous polyposis.

Vascular cyclooxygenase (COX)-2-dependent prostacyclin (PGI(2)) may affect angiogenesis by preventing endothelial activation and platelet release of angiogenic factors present in platelet α-granules. Thus, a profound inhibition of COX-2-dependent PGI(2) might be associated with changes in circulating markers of angiogenesis. We aimed to address this issue by performing a clinical study with celecoxib in familial adenomatous polyposis (FAP).

Antihypertensive and metabolic effects of telmisartan in hypertensive HIV-positive patients.

Background: Hypertension is more prevalent among HIV-infected individuals than in the general population and contributes to increased cardiovascular risk. The angiotensin II receptor blocker telmisartan is also a partial peroxisome proliferator activated receptor-γ agonist with documented effects on glucose and lipid homeostasis. The aim of this study was to evaluate the antihypertensive and metabolic effects of telmisartan in hypertensive HIV-positive patients.
