In order to support the creation of both artificial living organisms in the USA LANL "Protocell Assembly" project and programmable nano-biorobots in the EU "Programmable Artificial Cell Evolution" project, we used quantum mechanical (QM), density functional theory (DFT), the semiempirical PM3 method, and molecular mechanics (MM) software to investigate various complex photosynthetic systems bas...

Because solar energy is the most abundant renewable energy resource, the clear connection between human activity and global warming has strengthened the interest in photovoltaic science. Dye-sensitized solar cells (DSSCs) provide a promising low-cost technology for harnessing this energy source. Until recently, much of the research surrounding DSSCs had been focused on the sensitization of n-ty...

PURPOSE OF REVIEW In this article we consider the characteristics that are associated with chemical respiratory allergens, and that may be essential for effective sensitization of the respiratory tract. RECENT FINDINGS Chemical respiratory allergens share some characteristics with other chemical allergens, specifically chemical allergens that cause skin sensitization and allergic contact derm...

Ž . 2q Objective: To define the electrophysiologic mechanism s by which MCI-154, a putative Ca sensitizer, produces a positive inotropic response without a positive chronotropic response, we examined effects of MCI-154 on the action potential of atrial preparations and the membrane currents of atrial myocytes. Methods: The action potentias were recorded from left atrial and sinoatrial node prep...

Four photosensitizers were used to test inhibitory effect of Helicobacter pylori bacteria using low power helium: neon red laser radiation. Biopsies were collected from 176 patients and H. pylori were isolated, identified and bacterial suspension was prepared. Samples of this suspension were mixed with various low concentrations of the test sensitizer. The mixture samples were exposed to differ...

J Phys Org Chem. 2018;e3807. https://doi.org/10.1002/poc.3807 Abstract A physical‐organic study is described on the photodecomposition of dicumyl peroxide co‐adsorbed with the sensitizers 4,4′‐dimethylbenzil or chlorin e6 on fumed (nonporous) silica. Dicumyl peroxide was decomposed by the heterogeneous photosensitization and monitored by the desorption of products acetophenone, 2‐phenylpropan‐2...

A system for interstitial photodynamic therapy is used in the treatment of thick skin tumors. The system allows simultaneous measurements of light fluence rate, sensitizer fluorescence, and tissue oxygen saturation by using the same fibers as for therapeutic light delivery. Results from ten tumor treatments using delta-aminolevulinic acid (ALA)-induced protoporphyrin IX show a significant, trea...
