1. Photoprotective activity and increase of SPF in sunscreen formulation using lyophilized red propolis extracts from Alagoas
ABSTRACT The excessive sun exposure, coupled with lack of sun protection represents one of the biggest risks to the occurrence of skin cancer and photoaging. Recent strategies for photoprotection have included the incorporation of natural antioxidant and anti-inflammatory compounds, into sunscreens, and the oral administration of natural antioxidant extracts

2. Metronidazole concentration in the bloodstream following its topical application, at different concentration levels, on experimental skin wounds during healing by secondary intention
Abstract Purpose: To characterize qualitatively and quantitatively the absorption of metronidazole solution, in greater concentrations and for longer periods, when applied topically to an experimental open skin wound model. Methods: An open skin wound, 2 cm in diameter and total skin thickness was prepared, under anesthetic, in the dorsal region of 108 Wis

3. ÓXIDO DE ÍTRIO E ALUMÍNIO DOPADO COM Yb3+ E Er3+ INCORPORADO EM MEMBRANA DE POLIAMIDA
Lanthanide ions have special light emission, which can occur through descending and ascending energy conversion. Ascending energy conversion is especially interesting for bioapplications because excitation in the infrared region does not excite biomolecules and therefore does not interfere in detection, not to mention that it penetrates deeper in the skin. H

4. ELUCIDATION OF THE ELECTRONIC SPECTRUM CHANGES OF KA-Al3+ COMPLEX BY POTENTIOMETRIC TITRATION, FTIR, 13C RMN AND QUANTUM MECHANICS
Kojic acid (KA) is an organic acid widely used in pharmaceutical industry, mainly as a skin lightening agent. Based on the ability of KA to form complexes with ions, we found the most possible kind of complex formed with cation aluminum. KA-Al3+ complex structures were studied using potentiometric and spectrophotometric (UV) titrations, FTIR and 13C NMR. The

5. Evaluation of skin absorption of drugs from topical and transdermal formulations
ABSTRACT The skin barrier function has been attributed to the stratum corneum and represents a major challenge in clinical practice pertaining to cutaneous administration of drugs. Despite this, a large number of bioactive compounds have been successfully administered via cutaneous administration because of advances in the design of topical and transdermal f

6. Use of silicon for skin and hair care: an approach of chemical forms available and efficacy
Abstract Silicon is the second most abundant element on Earth, and the third most abundant trace element in human body. It is present in water, plant and animal sources. On the skin, it is suggested that silicon is important for optimal collagen synthesis and activation of hydroxylating enzymes, improving skin strength and elasticity. Regarding hair benefits

7. Effect of Genetic Strain and Sex on Water Absorption and Water-To-Protein Ratio in Chicken Meat
ABSTRACT The objectives of the present study were to evaluate the water and protein contents and the water-to-protein ratio of chicken parts before and after the pre-chilling process, to compare these results with the values officially recommended by the Brazilian Ministry of Agriculture, and to evaluate the effect of genetic strain and sex on these paramete

8. Bromelain: Methods of Extraction, Purification and Therapeutic Applications
Bromelain is a concoction of sulfhydryl proteolytic enzymes. Depending upon the site of extraction it can be regarded as either stem bromelain (SBM) (EC 3.4.22.32) or fruit bromelain (FBM) (EC 3.4.22.33). Bromelain remain enzymatic active over a broad spectrumand endure a range of pH (5.5 to 8.0) and temperature (35.5 to 71 ºC). It is one of the extensively

9. Aminoethoxyvinylglycine: isolated and combined with other growth regulators on quality of ‘Brookfield’ apples after storage
Growth regulators are used in the production of apples worldwide, especially to extend the harvest period and maintain postharvest quality. This study aimed to investigate the effects of applying aminoethoxyvinylglycine (AVG) in isolation as well as in combination with other growth regulators and postharvest techniques on the harvest quality and storage pote

10. Post-splenectomy infections in chronic schistosomiasis as a consequence of bacterial translocation
INTRODUCTION : Bacterial translocation is the invasion of indigenous intestinal bacteria through the gut mucosa to normally sterile tissues and internal organs. Schistosomiasis may cause alterations in the immune system and damage to the intestines, portal system and mesenteric lymph nodes. This study investigated bacterial translocation and alterations in

11. Properties of films obtained from biopolymers of different origins for skin lesions therapy
In this study, the effects of the origin of xanthan used, in combination with chitosan, to prepare films for the treatment of skin lesions were evaluated. The characteristics of the films obtained with xanthan commercially available for the food industry sector and xanthan originated from a fermentation process conducted in a pilot plant were compared.

12. Nutritional aspects of children and adolescents with epidermolysis bullosa: literature review
Epidermolysis Bullosa is a genetic disorder that affects mainly the skin, however, all others systems are influenced. The nutritional care of children and adolescents with Epidermolysis Bullosa is a key treatment strategy, since the energy needs are increased due to the disease's metabolism, burdening the immune system and cicatrization process, symptoms cau
