Progress in Cardiovascular Diseases

The management of patients with acute coronary syndromes (ACS) has evolved dramatically over the past decade and, in many respects, represents a rapidly moving target for the cardiologist and internist who seek to integrate these recent advances into contemporary clinical practice. Unstable angina and non-ST-segment elevation myocardial infarction (MI) comprise a growing percentage of patients with ACS and is emerging as a major public health problem worldwide, especially in Western countries, despite significant improvements and refinements in management over the past 20 years.

AIM OF THE STUDY: The aqueous extract of Terminalia chebular fruits was reported to have anti-hyperglycemia and anti-diabetic complication effects. The present study therefore investigated the protective mechanism of chebulic acid, a phenolcarboxylic acid compound isolated from the ripe fruits of Terminalia chebula against advanced glycation endproducts (AGEs)-induced endothelial cell dysfunction.

Terminalia chebula Retz. has been used in India for a long time to treat many diseases, and its extract was reported to have antidiabetic activity in vivo. In this study, T. chebula methanolic extract (TCE) containing 2.7 % chebulic acid was evaluated for its preventive effects against the formation of advanced glycation end products (AGEs) and endothelial cell dysfunction.

Human microvascular endothelial cells (HMVEC) from adult adipose tissue were cultured in MCDB 131 medium supplemented with 10% fetal bovine serum. Under these conditions, HMVEC from seven different donors had finite proliferative life spans ranging from 14.5 to 23.5 population doublings (PD), with a mean life span of 19 PD. Addition of 10% conditioned medium from activated human leukocyte cultures (BM Condimed) extended the life span of HMVEC to 31 to 41 PD, with a mean life span of 37 PD.

INTRODUCTION: Dental pulp stem cells (DPSCs) have received much attention as a promising population of stem cells in regenerative endodontics. Securing a good blood supply during regeneration is a challenging task because of the constricted apical canal opening, which allows only a limited blood supply. The aim of this study was to investigate any potential synergistic effects of dental pulp stem cells and endothelial cells (ECs) on osteo-/odontogenic and angiogenic differentiation in vitro.

Mechanisms of Ageing and Development

Oxidative damage by free radicals, which is the basis for the free radical theory of aging, has been well investigated within the context of oxidant/antioxidant balance. Age-associated disorders are believed to be associated with the time-dependent shift in the antioxidant/prooxidant balance in favor of oxidative stress. In this brief review, the importance of dietary antioxidant intervention on longevity and age-associated changes in bodily functions and diseases are discussed.

Current Opinion in Lipidology

Accumulating evidence suggests that oxidized fats and lipid oxidation products in the diet can contribute to the pathogenesis of atherosclerosis. The present review summarizes studies that show that oxidized fat and lipid oxidation products are present in human foods; that these compounds are absorbed by the intestine and appear in the blood circulation; and that these ingested substances can have deleterious cardiovascular effects in both humans and experimental animals.

Obesity promotes the development of several major cardiovascular risk factors. Moreover, excess adiposity may play a direct role in initiating atherosclerosis as fat cells are capable of affecting the systemic vasculature through a variety of mechanisms. Recent studies demonstrate that obesity per se may impair vascular endothelial function. This is important as endothelial dysfunction is a key factor in the pathogenesis of atherosclerosis and in triggering acute ischemic events.

The process of aging is accompanied by several modifications in the hemostatic system at different levels (blood coagulation, fibrinolysis, platelet activity, vascular endothelium). These changes may explain the higher incidence of arterial and venous thrombosis in the elderly compared to young people. Genetic and environmental factors modulate in different combinations the expression of proteins involved in the hemostatic process. Among the latter, diet and smoking habits play an important role, as well as physical exercise and, for women, hormonal status.

BACKGROUND: Nuclear factor-?B (NF-?B) signaling plays critical roles in physiological and pathological processes such as responses to inflammation and oxidative stress. METHODS AND RESULTS: To examine the role of endothelial NF-?B signaling in vivo, we generated transgenic mice expressing dominant-negative I?B under the Tie2 promoter/enhancer (E-DNI?B mice). These mice exhibited functional inhibition of NF-?B signaling specifically in endothelial cells.
