Applicability of phototherapeutic CO-releasing molecules (photoCORMs) is limited because they are activated by harmful and poorly tissue-penetrating near-ultraviolet light. Here, a strategy is demonstrated to activate classical photoCORM Mn2(CO)10 using red light (635 nm). By mixing in solution a triplet photosensitizer (PS) with the photoCORM and shining red light, energy transfer occurs from ...

As terahertz (THz) frequencies correspond to those of the intermolecular vibrational modes in a polymer, intense THz wave irradiation affects the macromolecular polymorph, which determines the polymer properties and functions. THz photon energy is quite low compared to the covalent bond energy; therefore, conformational changes can be induced "softly," without damaging the chemical structures. ...

Purpose : to describe a clinical case of successful application photodynamic therapy (PDT) in patient with leukoplakia the glans penis skin. Material and methods . For PDT, chlorin-type photosensitizer “Photolon” was used. The (lyophilized powder) diluted 200.0 ml 0.9 % sodium chloride solution, administered intravenously at dosage 1.5 mg/kg body weight. After 2.5 hours, intravenous laser blood...

The aim of this study was to investigate corneal enzymatic resistance following epithelium off and on riboflavin/UVA cross-linking (CXL). One hundred and fourteen porcine eyes were divided into four non-irradiated control groups and seven CXL groups. The latter comprised; (i) epithelium-off, 0.1% iso-osmolar riboflavin, 9 mW UVA irradiation for 10 min, (ii) disrupted epithelium, 0.1% hypo-osmol...

BACKGROUND Obesity has become a worldwide burden to public health in recent decades. Given that obesity is caused by an imbalance between caloric intake and expenditure, and that dietary fat is the most important energy source of all macronutrients (by providing the most calories), a valuable strategy for obesity treatment and prevention is to block fat absorption via the gastrointestinal pathw...

BACKGROUND Recent studies involving phototherapy applied prior to exercise have demonstrated positive results regarding the attenuation of muscle fatigue and the expression of biochemical markers associated with recovery. However, a number of factors remain unknown, such as the ideal dose and application parameters, mechanisms of action and long-term effects on muscle recovery. The aims of the ...

This is a comment on " The effect of low-level laser therapy on hearing. " [1] The first law of photochemistry, the Grotthuss-Draper law, states that light must be absorbed by a compound in order for a photochemical reaction to take place. Thus, when targeting the cochlea with laser light, it is essential to make sure that a sufficient amount of light reaches the target. Indeed, low-level laser...

Objective: The objective of the present review was to relate scientific production presented in last 5 years on effect photodynamic therapy using methylene blue photosensitizer microorganisms oral biofilm. Methods: systematic looking for research English primary studies such as randomized clinical trials and without randomization, individual case-control, qualitative descriptive studies, PubMed...

Aluminium was successfully extracted by treating an aluminium slag with aqueous NaOH under reflux conditions. This solution purified precipitation of silicon species addition HCl up to pH = 1, and used for preparing hydrocalumite (Ca2Al(OH)6Cl·2H2O) the coprecipitation method. The effect temperature on properties prepared microwave (MW) irradiation studied. Characterization obtained solid carri...
