Chondrocalcinosis, osteophytes and osteoarthritis.
An association between osteoarthritis (OA) and radiographic evidence of chon-drocalcinosis (CC) has been recognised for years. Crystals of calcium pyrophos-phate dihydrate (CPPD) may be found in synovial fluid from patients with OA who are relatively asymptomatic as well as from those who are experiencing an acute flare up of joint pain due to an attack of pseudogout. Whether CC is the cause of...
متن کاملOsteophytes, Enthesophytes, and High Bone Mass: A Bone-Forming Triad With Potential Relevance in Osteoarthritis
OBJECTIVE Previous studies of skeletal remains have suggested that both enthesophytes and osteophytes are manifestations of an underlying bone-forming tendency. A greater prevalence of osteophytes has been observed among individuals with high bone mass (HBM) compared with controls. This study was undertaken to examine the possible interrelationships between bone mass, enthesophytes, and osteoph...
متن کاملCRISPR-Cas: biology, mechanisms and relevance
Prokaryotes have evolved several defence mechanisms to protect themselves from viral predators. Clustered regularly interspaced short palindromic repeats (CRISPR) and their associated proteins (Cas) display a prokaryotic adaptive immune system that memorizes previous infections by integrating short sequences of invading genomes-termed spacers-into the CRISPR locus. The spacers interspaced with ...

متن کاملOsteophytes and the osteoarthritic femoral head.
The study describes the topography, morphology and growth of osteophytes in forty femoral heads removed from patients presenting with advanced osteoarthritis of the hip. In addition to standard histological techniques, radiography of serial bone slices in vivo bone labelling with tetracycline and 32P were used. The pattern of major osteophyte formation appeared to be influenced by the direction...
