The physical properties of fish liver and rat liver mitochondria were compared as a function of temperature and osmotic pressure. The data indicate that fish mitochondria are more flexible and swell at a more rapid rate over a 0 to 30 degrees C temperature range, whereas the rates of swelling at 30 to 40 degrees C are comparable. The swelling rates of both fish and rat mitochondria vary with te...

DNA-polyacrylamide hybrid hydrogels designed with covalent and double-stranded (dsDNA) crosslinks respond to specific single-stranded DNA (ssDNA) probes by adapting new equilibrium swelling volume. The ssDNA probes need to be designed with a base pair sequence that is complementary to one of the strands in a dsDNA supported network junction. This work focuses on tuning the hydrogel swelling kin...

PURPOSE To investigate the etiology of bilateral disc swelling in Japanese. METHODS Using Kitasato University's Department of Neuro-Ophthalmology medical records and fundus photographs of the period December 1977 through November 2010, we retrospectively identified 121 outpatients who had been initially confirmed with bilateral disc swelling. RESULTS The most common cause of the bilateral d...

OBJECTIVE The aim was to apply various maneuvers to perturb the volume of cultured chick cardiac myocytes and to evaluate the association between the swelling-activated chloride conductance and membrane distention. METHODS Swelling of single chick heart cells was induced by (1) reduction of external osmolarity; (2) elevation of intracellular osmolarity; (3) isosmotic urea uptake; and (4) posi...

and one observes that the vapor pressure is lowered correspondingly. If water is added, the matrix swells by the same pressure. The fact that water can be pressed out of a gel, and that the swelling pressure has been found to be equivalent to the lowering of its vapor pressure, suggests that the mechanism is the same as in the capillary system, i.e., that the hydrostatic pressure is equivalent ...

Biological tissues like intervertebral discs and articular cartilage primarily consist of interstitial fluid, collagen fibrils and negatively charged proteoglycans. Due to the fixed charges of the proteoglycans, the total ion concentration inside the tissue is higher than in the surrounding synovial fluid (cation concentration is higher and the anion concentration is lower). This excess of ion ...

Swelling soil leads to many types of constructional damages, deformations, and failures in the constructions’ roads, shoulders, foundations. Depending on amount swell, they can be insignificant, moderate, or massive. This paper presents a method for swelling stabilization by adding rice husk powder (RHP) variable percentages 0, 5, 10, 15, 20, 25 weight dry soil. The properties were investigated...

The purpose of this work was to study the relationship between water absorption, dimensional change (swelling) under cavity constraint and radial stress generation in resin matrix dental restorative materials. Water absorption was determined on disc specimens whilst swelling was determined on samples of materials restrained within cavities cut in cast polymethylmethacrylate and pressure generat...
