These data have suggested that high blood pressure led to compromised bone structure and mechanics, which might, in turn, result in a greater incidence of fracture. Previous studies were often carried out using male SHR particularly when characterizing bone phenotypes. Less is known about bone ...
Osteoarthritis comprises several joint disorders characterized by articular cartilage degeneration and persistent pain, causing disability and economic burden. The incidence of osteoarthritis is rapidly increasing worldwide due to aging and obesity trend
Creating template of object e.g. for making bone fracture healing plate by generating volume data set from x-ray examinationThe method involves producing a volume data set of the object (SB) using an x-ray system (8 to 10) that rotates around the object automatically, and producing the ...
The region where a long bone flares between the cylindrical shaft to the broadened epiphysis that containstrabecular boneand is a site ofmetabolic activity; also called the primary spongiosa. osteoblast Bone-synthesizing cell residing on thesurfaceof bone and secreting type I collagen-richprotein matri...
5 A, the bone collar that forms in the perichondrium is the precursor of the cortical region of long bones. Hypertrophic chondrocytes have been proposed to play a critical role in coordinating growth plate chondrogenesis and perichondrial osteogenesis, although the molecular parameters that regulate...
The primary aspect of the irradiation-induced loss of fracture resistance could be due to complete loss of plastic deformation (intrinsic toughness) after irradiation [7]. In addition, the increased plastic (residual) strain during the post-yield deformation was mostly related to the collagen phase...
Using these data, a data set was constructed as follows. (1) The radius and ulna on the X-ray (Fig. 2b) and CT images were manually segmented to extract 3D labels. The extraction of the region of interest allowed the objective anatomical features of the radius and ulna to be ...
X-ray images at 4 and 6 weeks after surgery showed that fracture recovery rate was much faster in patients with fracture and TBI than in patients with fracture only (Fig. 1a and Supplementary Fig. 1). Volumes of fracture callus, which is an important index of bone fracture healing, were ...
The fibula was removed using a semi-automatic script developed in-house that creates two disconnections near the tibio-fibular proximal growth plate and the tibio-fibular joint, and detecting the largest connected region (MATLAB 2018A, The MathWorks Inc., Natick MA, USA). For cases where the...
The central region of the scaffold (6 mm × 6 mm x 6 mm) was considered as representative volume and compared with the 3D theoretical design of the porous structure using a custom MATLAB® program to quantitatively evaluate the percent agreement between the design and the printed parameters. ...
