Circulating angiogenic cells (CAC) influence vascular repair through the secretion of proangiogenic factors and cytokines. While CAC are deficient in patients with diabetes and exercise has a beneficial effect on CACs, the impact of these factors on paracrine secretion from CAC is unknown. We aimed to determine whether the in vitro secretion of selected cytokines and nitric oxide (NO) from CAC ...

OBJECTIVES This study sought to identify loci for coronary artery calcification (CAC) in patients with chronic kidney disease (CKD). BACKGROUND CKD is associated with increased CAC and subsequent coronary heart disease (CHD), but the mechanisms remain poorly defined. Genetic studies of CAC in CKD may provide a useful strategy for identifying novel pathways in CHD. METHODS We performed a can...

BACKGROUND Data regarding coronary artery calcification (CAC) prognosis in diabetic individuals are limited to 5-years follow-up. We investigated the long-term risk stratification of CAC among diabetic compared with nondiabetic individuals. METHODS AND RESULTS Nine thousand seven hundred and fifteen asymptomatic individuals undergoing CAC scoring were followed for a median (interquartile rang...

D espite the high prevalence and morbidity of atrial fibril-lation (AF), the mechanisms of the disease are multi-factorial and remain poorly understood. The initiation of AF requires a trigger, and abnormal atrial substrate is necessary to sustain the arrhythmia. Although there are genetic predispositions to AF, 1 more traditional cardiovascular risk factors such as age, diabetes mellitus, hype...

The tumor line CAC-8, is a serially transplantable adenocarcinoma maintained in nude mice which originated from a hypercalcemic dog. Nude mice with CAC-8 developed a syndrome of humoral hypercalcemia of malignancy. CAC-8 contained a protein factor which stimulated adenylate cyclase of bone and kidney cells in vitro. The adenylate cyclase (AC) of rat osteosarcoma cell lines, ROS 17/2.8 (ROS) and...

BACKGROUND The use of atherosclerotic cardiovascular disease (ASCVD) risk to personalize systolic blood pressure (SBP) treatment goals is a topic of increasing interest. Therefore, we studied whether coronary artery calcium (CAC) can further guide the allocation of anti-hypertensive treatment intensity. METHODS We included 3733 participants from the Multi-Ethnic Study of Atherosclerosis (MESA...

Adsorption of gold cyanide on three types of Activated Carbons (ACs) has been investigated in batch and column adsorption conditions. Applied ACs have been derived from different crops precursors i.e., coconut shell (CAC), peach stone (PAC), and walnut shell (WAC). As peach stone and walnut shells are abundant agricultural residues in Iran, the activated carbons produced from these precurso...

Variations in the cerebral arterial circle (CAC) correlate with incidence of some cerebrovascular diseases and must be considered during surgical operations (1, 2). It also seems that different distribution of variations of the CAC is related to the race. This issue may partially explain the different incidences of some of the cerebrovascular diseases in different ethnic or racial groups (3-5)....

OBJECTIVE The goal of this study was to compare and contrast coronary artery calcium (CAC) with abdominal aortic calcium (AAC) in terms of their associations with traditional and novel cardiovascular disease (CVD) risk factors. METHODS AND RESULTS We measured both AAC and CAC using computed tomography scans in 1974 men and women aged 45 to 84 years from a multiethnic cohort. Traditional and n...
