Although information about the mechanism of apoptosis is rapidly increasing, critical roles of mitochondria in the regulation of cell death remain to be elucidated. Recent studies revealed that reactive oxygen species (ROS) in cells increase prior to the onset of DNA fragmentation, a late phase event in apoptosis. An overload of Ca 2 induces a classic type of membrane permeability transition (C...

Corneal decellularization has become an increasingly popular technique for generating scaffolds for corneal regeneration. Most decellularization procedures result in tissue swelling, thus limiting their application. Here, the use of a polysaccharide, dextran, to reduce swelling and conserve the native corneal structure during decellularization was investigated. Corneas were treated with 1% Trit...

due to the fact that many application processes take place at different temperature, better examining and understanding of swelling properties as a function of temperature is essential for such application. the temperature effect on the swelling properties of commercial polyacrylic acid (paa) hydrogel beads was investigated as a function of time and temperature. gel bead size, swelling equilibr...

Background Multicentric carpotarsal osteolysis (MCTO), a skeletal dysplasia presents in early childhood mimicking juvenile idiopathic arthritis (JIA). Recognition of this syndrome is essential to avoid unnecessary treatment with immunosuppressive agents because of different course and treatment. Case Report A 3-year-old boy presented with swelling and restriction of right wrist joint and left ...

The accuracy of joint angle measurement of the hand may be negatively influenced by joint swelling, deformation and other obstacles. We developed an alternative goniometer with clear ergonomic advantages, especially for the measurement of small joints. This new concept of goniometry is described and preliminary results on the reliability of the measurements are presented. The intraclass correla...

introduction: the aim of this study was to assess the effect of low-level laser therapy (lllt) on pain, swelling and maximum mouth opening in patients undergoing third molar surgery. methods: a prospective, randomized double-blind study was undertaken on 44 patients at the dental school, ahvaz jundishapur university of medical sciences, in 2015. a low-level laser was randomly applied on one of ...

Most studies on hydrogel swelling instability have been focused on a constrained boundary condition. In this paper, we studied the mechanical instability of a piece of disc-shaped hydrogel during free swelling. The fast swelling of the gel induces two swelling mismatches; a surface-inner layer mismatch and an annulus-disc mismatch, which lead to the formation of a surface crease pattern and a s...
