Physiologic Calcification of the Pineal Gland in Children on Computed Tomography: Prevalence, Observer Reliability and Association with Choroid Plexus Calcification

Academic Radiology, 2006
To evaluate the prevalence of physiologic pineal calcification, estimate observer variability, and examine the association with choroid plexus calcification.A retrospective review of hard copy head computed tomography films of 242 patients age younger than 16 years by two independent observers.Physiologic pineal calcification was present in 20% of the ...

[Intracranial physiological calcification on computed tomography (Part 1): Calcification of the pineal region].

No to shinkei = Brain and nerve, 1989
Of intracranial physiological calcification, common calcification of pineal region, choroid plexus of lateral ventricles and of basal ganglia was examined based on the frequency of occurrence of age and sex and type of CT scanners. Consecutive cases of 2877 (1450 males and 1427 females) underwent plain CT scanning were studied.

[Hydroxyapatite. 3. Physiology of hydroxyapatite and bone calcification].

Archivio stomatologico, 1990
The authors give a wide review of literature about the precipitation of hydroxyapatite, with particular attention to the latter studies about the collagene X and its leading role during this process.

An improved 45Ca protocol for investigating physiological mechanisms in coral calcification

Marine Biology, 1995
A sensitive experimental protocol using cloned corals (hereafter “microcolonies”) of the branching scleractinian coral Stylophora pistillata and 45Ca has been developed to enable reproducible measurements of physiological and biochemical mechanisms involved in calcium transport and compartmentalization during coral calcification. Cloned S.

Environmental and physiological conditions that led to the emergence of intracellular calcification

The emergence of intracellular calcification among marine unicellular eukaryotes in the Late Triassic (237-201 Ma) had profound consequences for the carbonate buffering capacity of the ocean. Research on the appearance of calcification typically focuses on the reasons that made this process successful on a global scale. The underlying environmental and

The physiological calcification process is replicated in a rat embryonic calvarial culture

2010
The present study was designed to investigate the progress of physiological calcification in the bone matrix by using a rat embryonic calvarial organ culture. We analyzed the content and concentration of calcium in the cultured bone matrix for assessing the organ culture system to replicate the progress in calcification.

[Intracranial physiological calcification on computed tomography (Part 2): Calcification in the choroid plexus of the lateral ventricles].

No to shinkei = Brain and nerve, 1988
In this paper, we describe calcification in the choroid plexus of lateral ventricles with a discussion of the frequency of occurrence in categories of age, sex, and laterality, and its correlation with pineal calcification. The study was conducted on 2877 consecutive cases (1450 males and 1427 females) that had plain CT scanning.
