Effect of remineralisation on the mechanical properties and tribological behaviour of human tooth dentine

open access: yesBiosurface and Biotribology, 2020
With ageing and pathological factors, dentine exposure becomes more and more commonplace in the clinic. The mechanical properties of dentine are far less than those of enamel. Once exposed, dentine exhibits a weak wear-resistance and then results in many

Amorphous calcium phosphates: synthesis, properties and uses in biomaterials [PDF]

open access: yes, 2010
This review paper on amorphous calcium phosphates (ACPs) provides an update on several aspects of these compounds which have led to many studies and some controversy since the 1970s, particularly because of the lack of irrefutable proof of the occurrence

Electrophoretic-deposited HAP nano-layer as a QCM-D sensor coating: effects of suspension concentration and electric-field strength

open access: yesBiosurface and Biotribology, 2018
This study investigates the fabrication of hydroxyapatite (HAP) nano-coating on a gold–quartz crystal sensor used for quartz crystal microbalance with dissipation (QCM-D) measurement using an electrophoretic deposition technique.

Meat and cancer: haemoglobin and haemin in a low calcium diet promote colorectal carcinogenesis at the aberrant crypt stage in rats [PDF]

open access: yes, 2003
High intake of red meat, but not of white meat, is associated with an increased risk of colon cancer. However, red meat does not promote cancer in rodents.

Automatic detection of calcium phosphate deposit plugs at the terminal ends of kidney tubules

open access: yesHealthcare Technology Letters, 2019
Kidney stones are a common urologic condition with a high amount of recurrence. Recurrence depends on a multitude of factors the incidence of precursors to kidney stones, plugs, and plaques. One method of characterising the stone precursors is endoscopic

Value of Calcium Hypophosphite and Other Calcium Compounds as Calcium Supplements in Calcium-Low Diets

open access: yesExperimental Biology and Medicine, 1949
SummaryCalcium hypophosphite is well suited to serve as a supplement for dietary calcium. To what extent the hypophosphite phosphorus is utilized by the organism remains uncertain. The ratio Ca/P in the diet may be varied within a wide range without affecting the calcification of the bones, provided the absolute quantities of each constituent are ...
