Abstract Background and Objective Whereas the biostimulative effect on tissues using low intensity laser therapy for treating many diseases has been described, photobiological basis adverse effects are not well understood. The aim of this study, experimental models, is to observe combined physical damage (laser) a chemical agent (hydrogen peroxide) Escherichia coli cultures bacterial plasmids. Materials Methods Survival E. AB1157 (wild type) BW9091 (xth − ) were used as an model assess...
Low intensity continuous wave and pulsed emission modes laser is used in treating many diseases the resulting biostimulative effect on tissues has been described, yet photobiological basis not well understood. The aim of this wok was to evaluate, using bacterial filamentation assay, effects Escherichia coli cultures exponential stationary growth phase. E. cultures, proficient deficient DNA repair, phase, were exposed low infrared laser, aliquots spread onto microscopic slides, stained by...
Biostimulation of tissues by low intensity lasers has been described on a photobiological basis and clinical protocols are recommended for treatment various diseases, but their effects DNA controversial. The objective this work was to evaluate infrared laser exposure survival bacterial filamentation in Escherichia coli cultures, induction lesions plasmids. In E. cultures plasmids exposed an at fluences used treat pain, were evaluated electrophoretic profile. Data indicate that the (i)...
Biostimulative effect of low intensity laser in tissues has been described on a photobiological basis and clinical protocols are recommended for treatment various diseases. The aim this work was to evaluate effects exposure the survival Escherichia coli cultures plasmid topological forms. plasmids were exposed infrared study bacterial electrophoretic profile, respectively. Data indicate laser: (i) had no E. wild type, endonuclease IV, exonuclease III, formamidopyrimidine DNA glycosylase/MutM...
In regenerative medicine, there are increasing applications of low-level lasers in therapeutic protocols for treatment diseases soft and bone tissues. However, doubts about effects on DNA, an adequate dosimetry could improve the safety clinical these lasers. This work aimed to evaluate DNA damage peripheral blood cells Wistar rats induced by red infrared at different fluences, powers, emission modes according protocols.Peripheral samples were exposed was accessed comet assay. other...
Semiconductor laser devices are readily available and practical radiation sources providing wavelength tenability high monochromaticity. Low-intensity red near-infrared lasers considered safe for use in clinical applications. However, adverse effects can occur via free radical generation, the biological of these from unusually fluences or doses have not yet been evaluated. Here, we evaluated survival, filamentation induction morphology Escherichia coli cells deficient repair oxidative DNA...
Laser devices emit monochromatic, coherent, and highly collimated intense beams of light that are useful for a number biomedical applications. However, low-intensity lasers, possible adverse effects laser on DNA still controversial. In this work, the expression XPA XPC genes in skin muscle tissue exposed to red infrared lasers was evaluated. Skin Wistar rats were at different fluences continuous mode emission. samples withdrawn total RNA extraction, cDNA synthesis, evaluation actin gene by...
Abnormalities in lungs caused by emphysema might alter their response to sepsis and the occurrence of acute lung injury (ALI). This study compared extension ALI intraperitoneal lipopolysaccharide (LPS) injection Wistar rats with without induced elastase. Adult male were randomized into four groups: control, sepsis, normal sepsis. Sepsis was induced, 24 h later euthanised. The following analysis performed: blood gas measurements, bronchoalveolar lavage (BAL), permeability histology. Animals...
