1. Blocking or enhancing effects of some basic emollients in UVA penetration
Abstract: Background: Topical agents used in combination with phototherapy or photochemotherapy may have both blocking or enhancing effects in ultraviolet rays. Objective: In this in vivo study, the effects of topical petrolatum, basis cream, glycerine, and olive oil on the transmission of ultraviolet A radiation were investigated. Methods: A test was per

2. Hyperpigmentation as a peculiar presentation of mycosis fungoides
Abstract Hyperpigmented mycosis fungoides is an extremely rare subtype of mycosis fungoides. It presents as multiple pigmented macules and patches without poikilodermatous changes and characterized by a CD8+ phenotype on immunohistochemistry. This report describes a typical case of hyperpigmented mycosis fungoides in a 62-year-old woman, who presented with a

3. C-reactive protein serum level in patients with psoriasis before and after treatment with narrow-band ultraviolet B
Abstract: Background: C-reactive protein is an inflammatory biomarker and its level increases in the serum of psoriatic patients. Its level is also associated with Psoriasis Area and Severity Index score. Objective: The aim of this study was to assess the decrement of serum C-reactive protein level with narrow-band ultraviolet B (NB-UVB) therapy. Methods:

4. Combination therapy of orally administered glycyrrhizin and UVB improved active-stage generalized vitiligo
Glycyrrhizin has been used clinically for several years due to its beneficial effect on immunoglobulin E (IgE)-induced allergic diseases, alopecia areata and psoriasis. In this study, glycyrrhizin, ultraviolet B light (UVB) or a combination of both were used to treat active-stage generalized vitiligo. One hundred and forty-four patients between the ages of 3

5. Low-level red laser therapy alters effects of ultraviolet C radiation on Escherichia coli cells
Low-level lasers are used at low power densities and doses according to clinical protocols supplied with laser devices or based on professional practice. Although use of these lasers is increasing in many countries, the molecular mechanisms involved in effects of low-level lasers, mainly on DNA, are controversial. In this study, we evaluated the effects of l

6. Evaluation of effects of photooxidized Vespa orientalis venom on memory and learning in rats
Wasp venom is mixture of complex proteins that have several physical and pharmacological properties. The photochemical detoxification of Vespa orientalis venom is expected to generate photooxidized venom sac extract (PVSE). Antigenically active PVSE is obtained by exposing the venom sac extract (VSE) of Vespa orientalis to ultraviolet radiation in the presen

7. Chromatic stability of acrylic resins of artificial eyes submitted to accelerated aging and polishing
Esthetics and durability of materials used to fabricate artificial eyes has been an important issue since artificial eyes are essential to restore esthetics and function, protect the remaining tissues and help with patients' psychological therapy. However, these materials are submitted to degrading effects of environmental agents on the physical properties o

8. Desenvolvimento de metodologia para monitorização terapêutica da azatioprina por cromatografia líquida de alta eficiência-UV (HPLC-UV) em transplantados renais / Development of a methodology for therapeutic drug monitoring of azathioprine by high performance liquid chromatography-UV (HPLC-UV) in renal transplant recipients
Azathioprine (AZA) is an immunosuppressant used in autoimmune pathologies like lupus erythematosus, Chrons disease, inflammatory bowel disease and against rejection in solid organs transplant. After more than 40 years of use, AZA continues exerting a central role in immunomodulatory regimens, due to the fact that it combines effectiveness, safety and low cos

9. Localized scleroderma: evaluation of the phototherapy therapeutic response / Esclerodermia cutânea: avaliação da resposta terapêutica à fototerapia
INTRODUÇÃO: A esclerodermia é uma doença auto-imune, de evolução crônica, caracterizada pela esclerose progressiva do tecido conjuntivo e alterações da microcirculação. A etiologia da doença ainda não está esclarecida. Em sua patogênese ocorre dano no endotélio vascular, com ativação inflamatória e imunológica, levando ao aumento da sínt

10. Evaluation of the effects of photooxidized Echis carinatus venom on learning, memory and stress
Snake venoms are a mixture of complex proteins, which have many physical and pharmacological properties. Photochemical detoxification has been suggested to generate photooxidized Echis carinatus venom product (POECVP). Antigenically-active photooxidized species of Echis carinatus venom could be obtained by exposing the venom to ultraviolet radiation (UVR) in

11. Glandula harderiana de ratos wistar como modelo para o estudo de efeitos fotodinamicos
The present work shows, experimentally, that the use of harderian glands of Wistar rats for the study of photodynamic applied to the diagnosis (PDD - of the English, Photo Dynamic Diagnosis) and medical treatment is possible (PDT - of the English, Photo Dynamic Therapy). In the case, the photodynamic action has as photo-sensitizer protoporphirin IX (PpIX), a

12. Estudo sobre a influencia do pH gastrico na absorção de metronidazol : implicações clinicas para a erradicação do Helicobacter Pylori
The addition of omeprazole to the classical triple therapy for eradication of He/icobacter pylori is suggested to enhance compliance through reducing ulcer symptoms and side effects, as well as overwhelming metronidazole resistance. The aim of this study was to investigate the effects af a tive day administration period of omeprazole on metronidazole pharmac
