Iridencleisis?

A 74- year-old woman was evaluated for progressive reduction of visual acuity in her left eye (OS). She had been submitted to glaucoma surgery in both eyes (OU) 7 years ago and to cataract surgery in OS 1 and a half years ago in another Institution. Current examination showed a visual acuity of no light perception in her right eye (OD) and 1/10 in OS, intraocular pressure (IOP) of 24 mmHg in OD and 2 mmHg in OS...

Immunoglobulin genes implicated in glioma risk

Both genetic and environmental factors are thought to be causal in gliomagenesis. Several genes have been implicated in glioma development, but the putative role of a major immunity-related gene complex member, immunoglobulin heavy chain γ (IGHG) has not been evaluated. Prior observations that IGHG-encoded γ marker (GM) allotypes exhibit differential sensitivity to an immunoevasion strategy of cytomegalovirus...

A novel modified acrylic bone cement matrix. A step forward on antibiotic deliv...

Currently the safe and responsible use of antibiotics is a world-wide concern as it promotes prevention of the increasing emergence of multiresistant bacterial strains. Considering that there is a noticeable decline of the available antibiotic pipeline able to combat emerging resistance in serious infection a major concern grows around the prosthetic joint infections once the available commercial antibiotic loa...

Laser fototérmico e sua interacção com a retina humana

Há vários efeitos resultantes da interacção da luz laser com os tecidos biológicos que podemos classificar em 5 tipos: efeito fotoquímico, fototérmico, fotoablativo, fotoablação induzida por plasma e fotodisrupção. Estes efeitos biológicos são modelados pelas propriedades ópticas dos tecidos: reflexão, absorção e dispersão e pelas características do feixe laser, nomeadamente o seu comprimento de onda (cdo) que ...

Displacement and strain field assessment of PDMS using digital image correlation

The main goal of this work is the characterization of the hyper-elastic mechanical behaviour of PDMS. The special specimens of PDMS (Sylgard® 184) were tested in a bi-axial tensile machine. The displacement and strain fields were measured using a commercial digital image correlation system (ARAMIS of GOM) during the tensile test. The experimental measurements are compared with numerical simulations, which use t...

Displacement and strain field assessment of PDMS using digital image correlation

The main goal of this work is to characterize the hyper-elastic mechanical behaviour of PDMS. For that, were made-up special specimens of PDMS (Sylgard® 184) for test them in bi-axial tensile machine. During the tensile test was used a commercial digital image correlation system (ARAMIS of GOM) to obtain de displacement and strain fields. These measurements are compared with numerical simulations which uses the...
