Temoporfin (Foscan®, 5,10,15,20‐Tetra(m‐hydroxyphenyl)chlorin), a Second Generation Photosensitizer†,‡
16-08-2011 | Mathias O. Senge; Johan C. Brandt, Photochemistry and Photobiology, 2011
Abstract This review traces the development and study of the second generation photosensitizer 5,10,15,20‐tetra(m‐hydroxyphenyl)chlorin through to its acceptance and clinical use in modern photodynamic (cancer) therapy (PDT). The literature has been covered up to early 2011.
An In Vitro Comparison of the Effects of the Iron Chelating Agents, CP94 and Dexrazoxane, on Protoporphyrin IX Accumulation for Photodynamic Therapy and/or Fluorescence Guided Resection
12-08-2011 | Blake, Emma; Allen, James; Curnow, Alison, Photochemistry and Photobiology, 2011
Abstract Photodynamic therapy (PDT) utilizes the combined interaction of a photosensitizer, light and molecular oxygen to ablate tumor tissue. Maximizing the accumulation of the photosensitizer protoporphyrin IX (PpIX) within different cell types would be clinically useful. Dermatological ...
A Non‐ionic Porphyrin as a Non Interfering DNA Anti‐Bacterial Agent
12-08-2011 | Sónia Mendes; Fábio Camacho; Tito Silva; Cecília R. C. Calado; Arménio Coimbra Serra; António M. d’A. Rocha Gonsalve ..., Photochemistry and Photobiology, 2011
Abstract The increasing interest in clinical bacterial photodynamic inactivation (PDI) has led to the search for photosensitizers with higher bactericidal efficiency and less side effects on the surrounding tissues. We present a novel non‐ionic porphyrin, the ...
Wheat Germ Agglutinin Modified Liposomes for the Photodynamic Inactivation of Bacteria†
12-08-2011 | Kewei Yang; Burkhard Gitter; Ronny Rüger; Volker Albrecht; Gerhard D. Wieland; Alfred Fahr, Photochemistry and Photobiology, 2011
Abstract Photodynamic inactivation (PDI) of bacteria is a promising approach for combating the increasing emergence of antibiotic resistance in pathogenic bacteria. To further improve the PDI efficiency on bacteria, a bacteria‐targeting liposomal formulation was investigated. A generation ...
Thermal Effectiveness of Different Infrared Radiators Employed in Rheumatoid Hand Therapy as Assessed by Thermovisual Examination
10-08-2011 | Radosław Rutkowski; Anna Straburzyńska‐Lupa; Paweł Korman; Wojciech Romanowski; Małgorzata Gizińska, Photochemistry and Photobiology, 2011
Abstract We conducted a thermovisual comparison of mean hand surface temperature changes upon local heating with two different IR sources. Sixty‐six patients with rheumatoid arthritis (47 women and 19 men; average age, 56.1 ± 8.6 years) were subjected to topical heat therapy for one hand ...
Clastogenic Plasma Factors in Psoriasis – Comparison of phototherapy and anti‐TNFα treatments
09-08-2011 | Ingrid Emerit; Joana Antunes; João Maia Silva; João Freitas; Teresa Pinheiro; Paulo Filipe, Photochemistry and Photobiology, 2011
Abstract As previously described, PUVA therapy induces chromosomal damage‐effects in psoriatic patients. This study evaluates whether these effects are transitory or persistent. In addition, we studied these effects after nUVB and anti‐TNFα treatments. Among forty responder patients, 10 ...
Temperature Correction of UV Spectral Solar Measurements for ICEPURE Project
30-07-2011 | Katarzyna Baczynska; John B O’Hagan; Andy J Pearson; Paul Eriksen; John B. O’Hagan; Andy J. Pearson, Photochemistry and Photobiology, 2011
Abstract UV solar spectra have been measured, using a double‐grating spectroradiometer, during population studies carried out across Europe for the EC Framework 7 funded ICEPURE project on the impact of climatic and environmental factors on personal UV radiation exposure and human health. ...
He‐Ne Laser‐Induced Improvement in Biochemical, Physiological, Growth and Yield Characteristics in Sunflower (Helianthus annuus L.)
25-07-2011 | Rashida Perveen; Yasir Jamil; Muhammad Ashraf; Qasim Ali; Munawar I qbal; Muhammad Raza Ahmad; Munawar Iqbal, Photochemistry and Photobiology, 2011
Abstract The water‐soaked seeds of sunflower were exposed to low power continuous wave He‐Ne laser irradiation of energies 0, 100, 300 and 500 mJ to evaluate the effect on various biochemical, physiological, growth and yield parameters of sunflower. The experiments which consisted of four ...
Design of a Coupled Bioluminescent Assay for a Recombinant Pyruvate Kinase from a Thermophilic Geobacillus
25-07-2011 | Soheila Mohammadi; Maryam Nikkhah; Mahboobeh Nazari; Saman Hzosseinkhani; Saman Hosseinkhani, Photochemistry and Photobiology, 2011
ABSTRACT A simple and rapid method using coupled bioluminescent assay was developed to determine level of ADP. ADP is involved in many biological reactions and ADP assay can be used for assaying some reactions universally by monitoring ADP formation or depletion. ADP analysis involves ...
Effects of Photoactivated Titanium Dioxide Nanopowders and Coating on Planktonic and Biofilm Growth of Pseudomonas aeruginosa
25-07-2011 | Andrea Polo; Maria Vittoria Diamanti; Thomas Bjarnsholt; Niels Høiby; Federica Villa; Maria Pia Pedeferri; Francesca ..., Photochemistry and Photobiology, 2011
Abstract We exploited the ability of photocatalytic titanium dioxide (TiO2) as an agent for the biofilm control. Two photocatalytic systems were investigated: a 3 g L−1 suspension of TiO2 nanopowder in demineralized water and glass slides coated with a TiO2 thin film, achieved by sol‐gel ...
