Intraparticle diffusion processes during acid dye adsorption onto chitosan.
The adsorption of five acid dyes onto chitosan was studied. The equilibrium capacities based on the Langmuir analysis were 1.54, 2.66, 1.11, 1.25 and 1.03 mmol/g chitosan for Orange 10 (AO10), AcidExpand

Enhancing the adsorption capacities of acid dyes by chitosan nano particles.
In the present study, nanochitosan emulsion has been produced in a suspension form by adding tripolyphosphate solution into a chitosan solution drop-wise. The adsorption capacities of four acid dyes,Expand

Secondary prevention of fragility fractures: instrumental role of a fracture liaison service to tackle the risk of imminent fracture.
The occurrence of fragility fractures is strongly associated with significant morbidity and mortality. Effective recommendations should be set to treat these patients punctually for secondaryExpand

Growth plate chondrocytes inhibit neo-angiogenesis -- a possible mechanism for tumor control.
Clinically, tumors seldom grow across the articular cartilage and physeal plate. It is believed that avascular cartilage may inhibit the neo-vascularization of tumor spread. The conditioned medium ofExpand

TGF-beta1 is the factor secreted by proliferative chondrocytes to inhibit neo-angiogenesis.
Growth plate is an avascular tissue, which has been reported to be capable of retarding tumor spread. It is believed that angiogenic inhibitor(s) exist to inhibit the neo-vascularization of tumor,Expand

Application of terahertz imaging to osteoarthritis
Osteoarthritis (OA) is the most common form of arthritis, caused by the breakdown of cartilage. A quantitative approach to monitor articular cartilage is a pressing need. Here, using a rabbit model,Expand

Terahertz pulsed imaging of osteoarthritis
Osteoarthritis (OA) is a common form of arthritis caused by the breakdown of cartilage. A non-destructive approach is needed for quantitative diagnosis of OA. Here, we demonstrate how terahertz imageExpand

Imaging of osteoarthritis using a hand-held terahertz probe
A hand-held terahertz (THz) probe system is being developed for medical use by Teraview Ltd. We use this prototype system to investigate the terahertz characteristics of osteoarthritis (OA). ExcisedExpand
