Photodynamic therapy in the treatment of microbial infections: Basic principles and perspective applications
Lasers in Surgery and Medicine - Tập 38 Số 5 - Trang 468-481 - 2006
Giulio Jori, Clara Fabris, Marina Soncin, Stefania Ferro, Olimpia Coppellotti, Donata Dei, Lia Fantetti, Giacomo Chiti, Gabrio Roncucci
AbstractBackground and ObjectivesPhotodynamic therapy (PDT) appears to be endowed with several favorable features for the treatment of infections originated by microbial pathogens, including a broad spectrum of action, the efficient inactivation of antibiotic‐resistant strains, the low mutagenic potential, and the lack of selectio...... hiện toàn bộ
Initiation of apoptosis and autophagy by photodynamic therapy
Lasers in Surgery and Medicine - Tập 38 Số 5 - Trang 482-488 - 2006
David Kessel, M. Graça H. Vicente, John J. Reiners
AbstractBackground and ObjectivesThis study was designed to examine modes of cell death after photodynamic therapy (PDT).Study DesignMurine leukemia L1210 cells and human prostate Bax‐deficient DU145 cells were examined after PDT‐induced photodamage to the endoplasmic ...... hiện toàn bộ
Cultured epithelial cells response to phototherapy with low intensity laser
Lasers in Surgery and Medicine - Tập 39 Số 4 - Trang 365-372 - 2007
Fernanda de Paula Eduardo, Dolores Úrsula Mehnert, Telma Alves Monezi, Denise Maria Zezéll, Mark M. Schubert, Carlos Eduardo, Márcia Martins Marques
AbstractBackground and ObjectivesLittle is known about the intracellular response of epithelial cells to phototherapy. The aim of this in vitro study was to analyze the effect of phototherapy with low‐energy lasers with different wavelengths and powers on cultured epithelial cell growth under different nutritional conditions.... hiện toàn bộ
Treatment of experimentally induced transient cerebral ischemia with low energy laser inhibits nitric oxide synthase activity and up‐regulates the expression of transforming growth factor‐beta 1
Lasers in Surgery and Medicine - Tập 31 Số 4 - Trang 283-288 - 2002
Mason C.P. Leung, Samuel Chun‐Lap Lo, Flora K.W. Siu, Kwok–Fai So
AbstractBackground and ObjectivesNitric oxide (NO) has been shown to be neurotoxic while transforming growth factor‐beta 1 (TGF‐β1) is neuroprotective in the stroke model. The present study investigates the effects of low energy laser on nitric oxide synthase (NOS) and TGF‐β1 activities after cerebral ischemia and reperfusion inju...... hiện toàn bộ
In vivo effects of low level laser therapy on inducible nitric oxide synthase
Lasers in Surgery and Medicine - Tập 41 Số 3 - Trang 227-231 - 2009
Yumi Moriyama, Jacqueline Nguyen, Margarete K. Akens, Eduardo H. Moriyama, Lothar Lilge
AbstractBackground and ObjectiveLow level laser therapy (LLLT) has been demonstrated to modulate inflammatory processes with evidence suggesting that treatment protocol, such as wavelength, total energy, and number of treatments determine the clinical efficacy. In this study, the effects of LLLT mediated by different wavelengths a...... hiện toàn bộ
Stem cell proliferation under low intensity laser irradiation: A preliminary study
Lasers in Surgery and Medicine - Tập 40 Số 6 - Trang 433-438 - 2008
Fernanda de Paula Eduardo, Daniela Franco Bueno, Patrícia Moreira de Freitas, Márcia Martins Marques, Maria Rita Passos‐Bueno, Carlos Eduardo, Mayana Zatz
AbstractBackground and ObjectivesPhototherapy with low intensity laser irradiation has shown to be effective in promoting the proliferation of different cells. The aim of this in vitro study was to evaluate the potential effect of laser phototherapy (660 nm) on human dental pulp stem cell (hDPSC) proliferation....... hiện toàn bộ
Irradiation at 780 nm increases proliferation rate of osteoblasts independently of dexamethasone presence
Lasers in Surgery and Medicine - Tập 38 Số 4 - Trang 332-336 - 2006
Neusa A. Fujihara, Karen Renata Nakamura Hiraki, Márcia Martins Marques
Transcranial application of low‐energy laser irradiation improves neurological deficits in rats following acute stroke
Lasers in Surgery and Medicine - Tập 38 Số 1 - Trang 70-73 - 2006
Luis De Taboada, Vera Celic, Sandra Leichliter‐Martha, Uri Oron, Amir Oron, Jackson Streeter
AbstractBackground and ObjectivesLow‐level laser therapy (LLLT) has been shown to have beneficial effects on ischemic skeletal and heart muscles tissues. The aim of the present study was to approve the effectiveness of LLLT treatment at different locations on the brain in acute stroked rats.... hiện toàn bộ
Modulations of VEGF and iNOS in the rat heart by low level laser therapy are associated with cardioprotection and enhanced angiogenesis
Lasers in Surgery and Medicine - Tập 38 Số 7 - Trang 682-688 - 2006
Hana Tuby, Lidya Maltz, Uri Oron
AbstractBackground and ObjectivesIt has been shown previously that low‐level laser therapy (LLLT) significantly reduces infarct size following induction of myocardial infarction in rats and dogs. The aim of the present study was to investigate the effect of LLLT on the expression of vascular endothelial growth factor (VEGF) and in...... hiện toàn bộ
Anti‐Inflammatory effects of low‐level laser therapy (660 nm) in the early phase in carrageenan‐induced pleurisy in rat
Lasers in Surgery and Medicine - Tập 40 Số 7 - Trang 500-508 - 2008
Emerson Soldateli Boschi, Carlos Eduardo Leite, Vasyl Custódio Saciura, Eduardo Caberlon, Adroaldo Lunardelli, Shanna Bitencourt, Denizar Alberto da Silva Melo, Jarbas Rodrigues de Oliveira
AbstractBackground and ObjectiveIn the classic model of pleurisy there is little evidence about the anti‐inflammatory effects of low‐level laser therapy (LLLT) as well the dosage characteristics, such as wavelength, total energy, number and pattern of treatment. In this study we investigated the potential effects of LLLT on modula...... hiện toàn bộ
