A method of synovial fluid preparation giving optimal hydroxyapatite detection as well as definitions of the threshold masses of hydroxyapatite in viscous synovial fluid detectable by x ray diffraction and scanning electron microscopy with energy dispersive analysis is reported. Use of an equal volume of 100% hydrazine with the synovial fluid optimised detection of hydroxyapatite. By x ray diff...

in this study, hydroxyapatite (ha) nanocrystals have been synthesized via chemical precipitation technique. diammonium hydrogen phosphate and calcium nitrate 4-hydrate were used as starting materials and sodium hydroxide solution was used as the agent for ph adjustment. the powder sample was evaluated by techniques such as scanning electron microscope, transmission electron microscope, fourier ...

Hydroxyapatite is chemically related to the inorganic component of bone matrix as a complex structure with the formula of Ca10(OH)2(PO4)6. Previous studies have reported the application of microsized hydroxyapatite to bone regeneration, but the result is not satisfied. The limitation comes from the size of hydroxyapatite. In addition, the duration of treatment is very long. The advantages of hy...

BACKGROUND Nanomaterials have unique advantages in controlling stem cell function due to their biomimetic characteristics and special biological and mechanical properties. Controlling adhesion and differentiation of stem cells is critical for tissue regeneration. METHODS This in vitro study investigated the effects of nano-hydroxyapatite, nano-hydroxyapatite-polylactide- co-glycolide (PLGA) c...

Background: Fluor albus, also known as leucorrhoea, vaginal discharge, or leukorrhea, is the name given to fluids that are secreted from genitals not blood. Pathological fluor albus can be caused by an infection in lower genitalia areas more proximal. This study aimed determine pattern of microorganisms cause pathological at Dr. Mohammad Hoesin General Hospital, Palembang, Indonesia.
