We study the efficacy of bone regeneration by using two differently sized allogeneic cancellous bone granules loaded with autologous cultured osteoblasts in a rabbit model. Critical-sized bone defects of the radial shaft were made in 40 New Zealand White rabbits. Small allogeneic bone granules (150–300 μm in diameter) loaded with cultured differentiated(More)
In this paper, we propose a novel postprocessing technique, based on the theory of projections onto convex sets (POCS), to reduce the blocking artifacts in transform-coded images. It is assumed, in our approach, that the original image is highly correlated. Thus, the global frequency characteristics in two adjacent blocks are similar to the local ones in(More)
In this paper, we propose a multi-bit watermarking technique for video sequences. An N-bit message is embedded in one unit of video fragment, in which a scene is employed as a watermarking unit. The proposed algorithm is fundamentally based on the three-dimensional discrete Fourier transform (DFT). In order to generate a watermark with optimum weighting(More)
Calcium phosphate-reinforced photosensitizer-loaded polymer nanoparticles have been developed for photodynamic therapy. Chlorin e6 (Ce6)-loaded core-shell-corona polymer micelles of poly(ethylene glycol)-b-poly(L-aspartic acid)-b-poly(L-phenylalanine) (PEG-PAsp-PPhe) were employed as template nanoparticles for mineralization with calcium phosphate (CaP).(More)
Isolated fractures of the greater trochanter (GT) are relatively rare. The diagnosis can be done on routine radiographs, but it is difficult to fully define the geographic extent of these injuries. This study examined the pattern and extent of an injury shown by magnetic resonance imaging (MRI) and radionuclide bone scan (RBS) in patients whose plain(More)
Oxidative stress and neuroinflammation are hallmarks of neurodegenerative diseases, which do not play independently but work synergistically through complex interactions exacerbating neurodegeneration. Therefore, the mechanism that is directly implicated in controlling oxidative stress and inflammatory response could be an attractive strategy to prevent the(More)
Nitric oxide (NO) is emerging as a key regulator of diverse plant cellular processes. A major route for the transfer of NO bioactivity is S-nitrosylation, the addition of an NO moiety to a protein cysteine thiol forming an S-nitrosothiol (SNO). Total cellular levels of protein S-nitrosylation are controlled predominantly by S-nitrosoglutathione reductase 1(More)
Imbalance between the accumulation and removal of nitric oxide and its derivatives is a challenge faced by all plants at the cellular level, and is especially important under stress conditions. Exposure of plants to various biotic and abiotic stresses causes rapid changes in cellular redox tone potentiated by the rise in reactive nitrogen species that serve(More)
Reports of coexisting avascular necrosis of more than one carpal bone are rare. We report coexisting avascular necrosis of the scaphoid and lunate in a 56-year-old woman with no history of using steroids or injury. We treated her with a radioscapholunate fusion with two angled 2.4 mm distal radius plates to stabilise the locking plate. At her 12-month(More)
Thenar muscle atrophy is a common finding in long-standing severe carpal tunnel syndrome (CTS). Combination of carpal tunnel release and Camitz opponensplasty has been used to treat severe CTS with thenar muscle atrophy. Camitz opponensplasty is beneficial for abduction, but provides little benefit to thumb flexion and pronation. This problem could be(More)
