To ascertain the effectiveness of topical antioxidant therapy on acute corneal inflammation, we have studied the effectiveness of topical treatment with a saline solution and with antioxidants such as 0.2% superoxide dismutase and 0.5% dimethylthiourea (DMTU) in a controlled experimental study. The evolution of the inflammatory process was evaluated by a(More)
An extracapsular cataract extraction was performed on both eyes of 24 rabbits. Irrigation for 10 min of the capsular bag of the left (test) eye with 8-12 cm3 of 1 litre of BSS-plus to which had been added 50 mg of 5-fluorouracil significantly inhibited proliferation of the anterior capsular epithelium as compared with the right (control) eyes identically(More)
Free radicals, especially the hydroxyl radical (OH.), are known to be toxic for several ocular structures including the cornea, lens, iris and retina through the initiation of lipid peroxidation of cell membranes. The oxidative damage to the iris epithelial-cell membranes, induced by the injection of hydrogen peroxide (H2O2) at different concentrations into(More)
Hydrogen peroxide (H2O2) has potent oxidant properties due to the action of free radicals (OH.) induced from its degradation. The free radicals specie derived from H2O2 are extremely toxic to the corneal endothelium and quickly induce corneal edema. In the present work, in order to ascertain the endothelial cell protection from viscoelastic substances, we(More)
The need to declare channels as global objects of the applications implemented according to the Distributed Programming Occam-CSP model, limits the desirable reusability of the software-modules of the said applications. The integration of other languages that follow the OO paradigm is not easy either. In this paper, easy solutions are proposed to augment(More)
CSP distributed programming model ooers formal bases that allow the development of high quality and secure distributed software for multicomputers. However, the model imposes restrictions that make it complicated to reuse software components developed with languages that follow the model. This problem is mainly due to each component in the application(More)
A component-based methodological approach to derive distributed implementations of parallel ODE solvers is proposed. The proposal is based on the incorporation of explicit constructs for performance polymorphism into a methodology to derive group parallel programs of numerical methods from SPMD modules. These constructs enable the structuring of the(More)
The work proposes a new classiication of parallel algorithm schemes to program multicomputer systems, these schemes being called paradigms. The proposed classiication is intended to improve the programmabil-ity and portability of distributed parallel algorithms derived with these paradigms. In order to design algorithms and to implement applications based(More)
A component-based methodology to derive parallel stiff Ordinary Differential Equation (ODE) solvers for multi-computers is presented. The methodology allows the exploitation of the multilevel parallelism of this kind of numerical algorithms and the particular structure of ODE systems by using parallel linear algebra modules. The approach furthers the(More)
Top choices and rankings are applied in situations where a fixed set of choice alternatives (products, candidates) is offered to a group of decision makers, each of whom is requested to pick or rank, respectively, a subset containing some number of preferred alternatives. In this framework, random utility models are used for modelling choice and ranking(More)
