2. Effects of gamma radiation on the stability and degradation kinetics of phenolic compounds and antioxidant activity during storage of (Oryza sativa L.) black rice flour
Abstract The effects of gamma radiation (0, 1, 2 and 3 kGy) were used to evaluate the stability and thermal degradation kinetics of anthocyanins, as well as the stability of total phenolic compounds (TPC) and antioxidant activity at different temperatures (4, 25, 35 and 45 °C) during the storage (0, 30, 60, 90 and 120 days) of black rice flour. This flour c

3. RADIOACTIVE CEMENT OF PMMA AND HAP-Sm-153, Ho-166, OR RE-188 FOR BONE METASTASIS TREATMENT
RESUMO Polymethylmetacrylte (PMMA) é um composto utilizado na indústria e desde os anos 80's também tem sido empregado nas áreas odontológica e biomédica como constituinte de cimentos ósseos. A hydroxyapatite (HAp) é uma biocerâmica produzida naturalmente nos ossos. Esses dois componentes são constituintes fundamentais no preparo de cimentos ósseo

4. Alterations in Biomarkers Associated with Sterility in Pectinophora gossypiella (Saunders) Induced by Gamma Irradiation
ABSTRACT Nowadays, radiation technology is widely used to produce changes in Biosystems. The goal of this work is to determine the variation induced male Pectinophora gossypiella in gamma-irradiated as pupae using 50Gy and 150Gy. Comparing elements composition and DNA (using RAPD-PCR) between substerile 50Gy and the sterile dose 150Gy in P. gossypiella showe

5. Tazarotene gel with narrow-band UVB phototherapy: a synergistic combination in psoriasis
Abstract: BACKGROUND: Narrow-band UVB (NB-UVB) has been shown to be one of the most effective treatment modalities for psoriasis. Tazarotene, a known effective anti-psoriatic modality, when combined with NB-UVB may enhance the therapeutic success. OBJECTIVE: To study clinical efficacy and safety of combination of NB-UVB with topical tazarotene 0.05% gel in

6. Uso combinado de radiación UV-C y biorecubrimiento de quitosán con aceites esenciales para el control de hongos en papaya Maradol
Abstract Anthracnose and soft rot cause deterioration of quality as well as large losses during post-harvest handling of papaya fruits. The single strategies for disease control is little efficient. We analyzed the effect of to integrate control strategies on the incidence of disease caused by the inoculation of spores of the fungi Colletotrichum gloeospori

7. Use of photodynamic inactivation for in vitro reduction of prevalent bacteria in Fournier's Gangrene
ABSTRACT Fournier's Gangrene (FG) is an infectious disease caused by several synergic microbes, with high morbidity and mortality rates; therefore, the search for new less invasive and mutilating treatments, with faster recovery, has been proposed. Surgical intervention, the use of several systemic and topic antibiotics, and hyperbaric oxygen therapy are cur

8. Radiation-induced Changes in the Electrophoretic Profile of Serum Albumin
ABSTRACT Albumin protein profiles were investigated in electrophoresis system in relation to the whole body exposition to the radiation. Two groups of rats Wistar were set up as the control (CG) and the irradiated one (IG). The IG was exposed to Co-60 at a dose of 5 Gy. After a 72-hour exposition, 300 μL of blood was collected in the inferior vena cava, ren

10. The effects of ultraviolet B (UV-B) irradiation on color quality and decay rate of Capia pepper during postharvest storage
Abstract The current study demonstrates that the ultraviolet-B (UV-B) irradiation not only helps in improvement of the red color of the peppers but also reduces their rate of decay. The Capia peppers were harvested at their full red ripe stage and subjected to the UV-B treatment at doses 4.46 kJ m–2 (UV-B 15) and 8.93 kJ m–2 (UV-B 30). Post irradiation,

11. Automated and observer based light field indicator edge evaluation in diagnostic X-ray equipment
Abstract Introduction To analyze edge detection and optical contrast calculation of light field-indicators used in X-ray via automated- and observer-based methods, and comparison with current standard approaches, which do not give exact definition for light field edge determination. Methods Automated light sensor array was used to measure the penumbra zone

12. Biological X-ray irradiator characterization for use with small animals and cells
This study presents the characterization of an X-ray irradiator through dosimetric tests, which confirms the actual dose rate that small animals and cells will be exposed to during radiobiological experiments. We evaluated the linearity, consistency, repeatability, and dose distribution in the positions in which the animals or cells are placed during irradia
