Joint Bone Spine, 2005
Apart from clinical parallels, similarities in the pathogenesis of arterial and articular cartilage calcification have come to light in recent years. These include the roles of aging, of chronic low-grade inflammation and of genetic and acquired dysregulation of inorganic pyrophosphate (PP(i)) metabolism.

Physiologic and Pathologic Calcifications of Head and Neck Significant to the Dentist
Dental Clinics of North America, 2021This article aims to help the practitioner identify structures found in routine three-dimensional imaging studies of the head and neck region and understand their significance and possible need for intervention. The prevalence of advanced imaging in dental practice, especially cone beam computed tomography, highlights the need to recognize and identify

Physiological and Pharmacological Regulation of Biological Calcification
1991Biological calcification is a highly regulated process which occurs in diverse species of microorganisms, plants, and animals. Calcification provides tissues with structural rigidity to function in support and protection, supplies the organism with a reservoir for physiologically important ions, and also serves in a variety of specialized functions. In

Recent Advances in Physiology of Calcification
The Journal of Bone & Joint Surgery, 1964The biochemistry and physiology of the local mechanism of calcification is one of the most important unsolved problems in orthopaedics and medicine. Current studies suggest that the calcifying substrate of matrix consists of a mixture of fibrous and globular proteins, protein-protein complexes, mucoproteins, lipoproteins, and other substances in the ...

Physiological variables involved in heart valve substitute calcification
Expert Opinion on Biological Therapy, 2009Biochemical, histological and genetic studies using in vitro/in vivo models have demonstrated that pathological calcification of bioprosthetic heart valves (BHV) is regulated by various mechanisms associated with physiological variables. The major objective of this review is to characterize physiological variables involved in BHV calcification.

Physiologic and pathologic calcifications and ossifications in the face and neck
European Radiology, 2007The aim was to give a systematic presentation of physiologic and pathologic calcifications and ossifications in the face and neck with a special emphasis on clinical relevance. In a sometimes subacute setting one should recognize specific calcifications which often lead to important diagnoses such as fungal sinusitis or sclerosing labyrinthitis.

Current Concepts of the Physiology and Biochemistry of Calcification
Clinical Orthopaedics and Related Research, 1981The current picture of the process of biological calcifications portrays the cells within the calcifying tissues as central factors controlling the deposition of mineral crystals in the extracellular matrix. The cell responds to hormones and second messengers, and other changes in its environment, regulating the concentration of ions within the ...

The Biochemistry and Physiology of Bone, vol 4: Calcification and Physiology
JAMA: The Journal of the American Medical Association, 1977The latest volume in this excellent series fulfills a stated desire of the editor to produce a relatively complete treatise on bone. Although not originally planned, volume 4 became an obvious necessity to cover several important topics omitted from preceding issues.

Basal Ganglia: Physiologic Calcifications
2017Basal ganglia (BG) calcifications are a common cause of either confusion or misinterpretation, particularly when the degree of calcification is only mild or unilateral. In general, although there is no landmark recent literature regarding the incidence of idiopathic, incidence BG calcifications on CT, the incidence is thought to be less than 2 % in the

Increased signal intensity on T1-weighted MR image of physiologic intracranial calcifications
Computerized Medical Imaging and Graphics, 1991Among 1500 MR studies of the brain, performed during 1 year, there were six cases of physiologic calcifications (four in the falx cerebri, two in the deep gray matter) that revealed high signal intensity on T1- and variable signal on T2-weighted images.
