The objective of this work was to develop and characterize liposomes loaded with silver nanoparticles (LAgNPs) to show improvement in stability characteristics. AgNPs were prepared by the green synthesis method with Aloe vera gel extract and exposure to sunlight. Liposomes were prepared by the modified r...
Objetivou-se avaliar o perfilhamento da Brachiaria brizantha cv. Piatã, como base para identificação das frequências e alturas pós-corte mais adequadas para essa gramínea forrageira. Em um esquema fatorial 2 x 2, foram estudadas combinações entre duas frequências de corte (95% e máxima intercep...

El objetivo de este trabajo fue determinar la prevalencia de valores inadecuados de esta vitamina en jóvenes sanos de Asunción e identificar los posibles fact...
Abstract: Solar urticaria is a rare form of physical urticaria mediated by immunoglobulin E. The lesions appear immediately after the sun exposure, interfering with the patient's normal daily life. Omalizumab, a monoclonal anti-IgE antibody, has been recently approved for the treatment of chronic spontan...
Abstract: Background: Exposure to UVR provides benefits related to vitamin D synthesis, but also causes harms, since UVB is considered a complete carcinogen. There is no definition of the level of sun exposure and the proportion of exposed body required for proper synthesis of vitamin D in the skin with...

Abstract BACKGROUND: Excessive sun exposure is the major risk factor for skin cancer. Thus, sun exposure behavior is the major focus for prevention of this disease, since it is potentially modifiable. Increasing the knowledge on sun related habits and other skin cancer risk factors is fundamental in the...

Abstract: Background: Most of the organism's vitamin D (VD) is obtained through the cutaneous synthesis after exposure to the sun's UVB radiation. Sunscreens are indicated for the prevention of actinic damage to the skin, however, there are few clinical trials assessing the synthesis of cutaneous VD in ...
