Sentences with phrase «using trabecular»

One innovative aspect of the study was the measurement of bone texture of the lumbar spine using trabecular bone score (TBS)- the first use of this technique in adolescent athletes.

Not exact matches

When the team scanned hand bones from four members of A. africanus that lived in South Africa between 2 million and 3 million years ago, they found that the pattern of the trabecular bone was asymmetrical, as in modern humans and Neandertals that use tools frequently (as they also show in their study).

Trabecular architecture in the thumb of Pan and Homo: implications for investigating hand use, loading, and hand preference in the fossil record

The research, titled «Human - like hand use in Australopithecus africanus, shows that Australopithecus africanus,» a 3 - 2 million - year - old species from South Africa traditionally considered not to have engaged in habitual tool manufacture, has a human - like trabecular bone pattern in the bones of the thumb and palm (the metacarpals) consistent with forceful opposition of the thumb and fingers typically adopted during tool use.

Here we show that Australopithecus africanus (~ 3 to 2 million years ago) and several Pleistocene hominins, traditionally considered not to have engaged in habitual tool manufacture, have a human - like trabecular bone pattern in the metacarpals consistent with forceful opposition of the thumb and fingers typically adopted during tool use.

Using automated morphological filters, the cortical bone is defined and extracted from the underlying trabecular structure to create two 3D models, one of the cortex and one of the trabecular bone that can be analysed separately.

We test the sensitivity of the morphological parameters used to create these 3D models, demonstrating that the parameters defined here are robust and can provide accurate measures of cortical thickness, relative bone density, trabecular orientation, trabecular thickness and degree of anisotropy.

The effect of glucocorticoid treatment is most prominent on trabecular bone and is therefore likely to be larger on vertebral bone than on hip bone.3 Glucocorticoids are associated with an increased rate of fracture, and higher doses and longer use of glucocorticoids are associated with higher risks of fracture.4 Compared with patients not taking glucocorticoids, the risk of hip and vertebral fracture among patients taking glucocorticoids is increased by 60 % and 160 %, respectively.4 Among 80 - year - old patients, the hip fracture risk is increased by a magnitude of 2.1 and is independent of BMD.5 Most studies indicate that fracture risk is increased following at least 3 months of treatment with daily doses of 5 mg of prednisolone or more in older men and women.4

Our lab has recently shown that endogenous TGF - Î ² 2 expression can be markedly and significantly attenuated in human trabecular meshwork cells and porcine anterior segments using the compound XJB -5-131, a novel antioxidant that targets a cell's mitochondria.
