This article is also accessible online at: http://BioMedNet.com/karger Dear Sir, A recent study of corneal swelling by Aakre and Doughty [1] found two regimes in the time course of tissue fluid imbibition. We are pleased to note that this confirms our discovery made over 10 years ago at the University of New South Wales, Sydney [2, 3]. We first reported these results in 1986–1988 to meetings of...

Abstract The wood-water interactions of modified beech wood ( Fagus sylvatica L.) were studied. Specimens thermally at 180 (TM 1 ), 200 2 ) and 220 °C 3 acetylated (Acet), melamine formaldehyde (MF) resin (Mel) modified. Afterwards, the water vapour characteristics, i.e. sorption isotherms, equilibrium moisture content (EMC), dimensional stability specimens conditioned 30, 65 90% RH liquid abso...

Treatment of diseases on the molecular level by genetic material is limited by effective delivery mechanisms. We focused on the synthesis of a pH-sensitive gene delivery vehicle based on dimethylaminoethyl methacrylate (DMAEMA) with tunable swelling, cross-linking density, and DNA release kinetics within the endosomal pH range. Our strategy, which utilized a single step for DNA encapsulation, e...

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...

Berbamine loaded chitosan-agarose microspheres were prepared using a water-in-oil emulsion technique. Optimum preparing parameters were determined by orthogonal experiments as follows: ratio of berbamine to chitosan (w/w) is 1:10; percentage of emulsifier (span 80, v/v) is 6%; volume of glutaraldehyde is 2 mL; and reaction temperature is 70 °C. Under these optimal conditions, the encapsulation ...

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...
