Regulation of the Sodium-Phosphate Cotransporter Pit-1 and its Role in Vascular Calcification.
Authors: Gonzalez M, Martínez R, Amador C, Michea L
Vascular calcification is caused by the deposition of basic calcium phosphate crystals in blood vessels, myocardium, and/or cardiac valves. Calcification decreases artery wall compliance, and arterial calcification is associated to mortality in hyperphosphatemic renal failure and diabetes mellitus. The calcification of the tunica media characterizes the arteriosclerosis observed with age, diabetes and end stage-renal disease, and it can develop independently from intima calcification. As part of the vascular calcification mechanism, vascular smooth muscle cells (VSMC) experience a transition from a contractile to an osteochondrogenic phenotype and a sequence of molecular events that are typical of endochondral ossification. The c......

Collateral theory and vascular lesion treatment.
Authors: Wu Y
The correlation between the collateral system of traditional Chinese medicine (TCM) and the vascular system of Western medicine was approached and the conception of "Mai" was analyzed. It was pointed out that "Mai" is an independent viscera with certain structure, function, and characteristics in metabolism. Ancient TCM physicians basically share the same knowledge on the vascular system with biomedicine in terms of its anatomical structure, but the distinctive TCM theory on qi-blood correlation can enrich the contents of the vascular system. The concept of "collateral-vascular system disease" was proposed based on ancient TCM literature and a clinical epidemiology survey on 3,469 cases with arteriosclerosis, approached by common pathological steps. The pathogenesis of ve......

Quick Identification of acute Chest pain patients - Study (QICS)
Background:
Often patients with acute chest pain are admitted and extensively investigated. Investigations are costly and could induce unnecessary complications, especially with invasive diagnostics. Nevertheless, chest pain patients have high mortalities. Fast identification of high-risk patients is crucial. Therefore several strategies have been developed including specific symptoms, signs, laboratory measurements, and imaging.Study designThe Quick Identification of acute Chest pain Study (QICS) will investigate whether a combined use of specific symptoms and signs, electrocardiography, routine and new laboratory measures, adjunctive imaging including electron beam (EBT) computed tomography (CT) and contrast Multislice CT will have a high diagnostic yield for patients with acute chest pa......

Association between circulating osteoprogenitor cell numbers and bone mineral density in postmenopausal osteoporosis
Conclusion In postmenopausal osteoporotic women, a reduced number of circulating AP+ cells and increased levels of AP+/CD34+, OCN+, and
OCN+/CD34+ cells are associated with reduced bone mineral density, the interpretation of such a cellular imbalance needing
exploration.

Oregano helps stop inflammation and bone degeneration
Chronic inflammation is known to be associated with increased episodes of heart attacks and with such autoimmune disorders as diabetes, lupus, rheumatoid arthritis and multiple sclerosis among others. One way to fight such inflammation is through nutrition - and specifically, as researchers from the University of Bonn and the ETH Zurich have discovered, by including oregano in our diets. According to a study conducted by the Swiss researchers, oregano is the "ultimate inflammation fighter" thanks to its active ingredient betacaryophyllin (E-BCP). The researchers experimented on mice by administering them with E-BCP. They found that E-BCP helped 7 out of every 10 mice recover from inflamed paws. "Our results have revealed that E-BCP inhibits inflammation," says Professor Dr. Andreas Zimm......

Smooth muscle progenitor cells: friend or foe in vascular disease?
Authors: van Oostrom O, Fledderus JO, de Kleijn D, Pasterkamp G, Verhaar MC
The origin of vascular smooth muscle cells that accumulate in the neointima in vascular diseases such as transplant arteriosclerosis, atherosclerosis and restenosis remains subject to much debate. Smooth muscle cells are a highly heterogeneous cell population with different characteristics and markers, and distinct phenotypes in physiological and pathological conditions. Several studies have reported a role for bone marrow-derived progenitor cells in vascular maintenance and repair. Moreover, bone marrow-derived smooth muscle progenitor cells have been detected in human atherosclerotic tissue as well as in in vivo mouse models of vascular disease. However, it is not clear whether smooth muscle progenitor cells ......

Diabetes, oxidative stress, nitric oxide and mitochondria function.
Authors: Friederich M, Hansell P, Palm F
The role of altered mitochondria function has recently emerged as an important mechanism for the development of diabetic complications. Altered mitochondria function has also been implicated in the ageing process, defective insulin secretion, hypertension, arteriosclerosis, ischemia-reperfusion injury and apoptosis. Normally, the mitochondria are associated with ATP production using primarily pyruvate as the substrate, but recent reports indicate that tissue specific preferences exist. Also, the mitochondria are a substantial source of superoxide production, preferentially during states of elevated intracellular glucose concentrations. The mitochondria function is regulated by several factors including nitric oxide, oxidative stress, mammalian t......

[Biology of arterial ageing and arteriosclerosis.]
Authors: Cottart CH, Laguillier C, Nivet-Antoine V, Klimczak C, Sebban C, Beaudeux JL
Arterial ageing - arteriosclerosis - is characterised by both thickening and stiffening of the walls of large and medium arteries. The molecular and cellular mechanisms (i.e. endothelial dysfunction, matrix remodelling, ...) involved in this process are complex, and at least in part common to atherosclerotic injury. Arterial stiffness is strongly associated with cardiovascular disease and an increased risk of morbidity and mortality. The aim of this review is to provide an update on the pathophysiology and the biological process of arterial ageing and to underline the main difference with atherosclerosis damage process in particularly during the calcification step.

Better Targeting Of Stem Cells As Medication: Arteriosclerosis May Soon Be A Thing Of The Past
Until now, it has been extremely difficult to control stem cells in such a way that they grow into new blood vessels outside the body, or -- when injected into an organ -- lead to the creation of new small blood vessels and tissue repair. New research has resulted in a method whereby the cells can be instructed. This is a great advance towards curing numerous life-threatening diseases. (Source: ScienceDaily Headlines)...

Quiz Page May 2009: Nephrotic-Range Proteinuria Without Extensive Glomerular Disease
A 47-year-old Haitian woman of African decent was referred for nephrotic-range proteinuria and microscopic hematuria. Her blood pressure was 100/70 mm Hg, and physical examination findings were within normal limits, with no evidence of pedal edema. Laboratory testing showed the following values: creatinine, 0.7 mg/dL [62 μmol/L]; estimated glomerular filtration rate, greater than 60 mL/min/1.73 m2 (>1.0 mL/s/1.73 m2); total serum protein, 5.9 g/dL (59 g/L); and albumin, 3.0 g/dL (30 g/L). Urinalysis showed normal-colored urine with protein (3+) and blood (3+), with no red blood cells, white blood cells, fat bodies, or fatty casts. A 24-hour urine collection measured 7,030 mg of protein. A kidney biopsy showed only focal and mild effacement of the visceral epithelial cell foot processes wi......
