Self-calcifying, self-replicating nanoparticles have been isolated from calcified human tissues. However, it is unclear if these nanoparticles participate in disease processes. Therefore, this study was designed to preliminarily test the hypothesis that human-derived nanoparticles are causal to arterial disease processes. One carotid artery of 3 kg male rabbits was denuded of endothelium; the c...

BACKGROUND Unknown cell-culture contaminants were described by Kajander and Ciftçioğlu in 1998. These contaminants were called nanobacteria initially and later calcifying nanoparticles (CNPs). Their exact nature is unclear and controversial. CNPs have unique and unusual characteristics, which preclude placing them into any established evolutionary branch of life. AIM The aim of this systemati...

Pathological calcification is becoming recognized as an important feature in the dynamics of a variety of diseases, such as renal stone, atherosclerosis, pulp stones, scleroderma and arthritis, etc. from which millions of human beings suffer in all ages. Nanobacterium sanguineum is the first calcium phosphate mineral containing nanoorganism isolated from human blood that causes pathological dis...

Present review article describes main causes of chronic kidney disease a major health problem public health problem round the globe. Disease has multiple etiologies related to sequential pathophysiological stages. It has major concern with chronic changes in renal structure and that severely alter glomerular filtration rate in patients. This article explains CKD biomarkers in brief i.e., serum ...

Biologists typically define living organisms as carbon and water-based cellular forms with “selfreplication” as the fundamental trait of the life process. However, this standard dictionary definition of life does not help scientists to categorize self-replicators like viruses, prions, proteons and artificial life. CNP also named nanobacteria were discovered in early 1990s as about 100 nanometer...

The etiology of dental pulp stones, one type of extraskeletal calcification disease, remains elusive to date. Calcifying nanoparticles (CNPs), formerly referred to as nanobacteria, were reported to be one etiological factor in a number of extraskeletal calcification diseases. We hypothesized that CNPs are involved in the calcification of the dental pulp tissue, and therefore investigated the li...

Calcifying odontogenic cyst is a developmental odontogenic cyst first described by Gorlin in 1962. It is considered as an extremely rare condition and shows extensive diversity in its clinicopathological appearances and biologic behavior. In this report a rare case of calcifying odontogenic cyst with ameloblastic proliferation (an extremely rare histologic variant) with one year follow – up is ...
