1. The protective effects of β-sitosterol and vermicularin from Thamnolia vermicularis (Sw.) Ach. against skin aging in vitro
Abstract: Aged skin, featured with dryness and wrinkles, has received mounting attention due to its adverse influences on beauty. β-Sitosterol and vermicularin are two common active ingredients of Thamnolia vermicularis (Sw.) Ach., a traditional Chinese medicine, of which the anti-aging effect has been discovered. Their protective performance against skin a

2. Avaliação de diferentes fatores na remoção de remazol brilliant blue de soluções aquosas por adsorção em fibras de cana de açúcar e coco verde
RESUMO As indústrias têxteis, durante o processo de tingimento, liberam uma grande quantidade de corantes na água. Além do seu efeito visual e seus impactos adversos em relação à fotossíntese e demanda química de oxigênio, muitos corantes sintéticos são tóxicos, recalcitrantes, mutagênicos e carcinogênicos. Dessa forma, novas alternativas de t

4. Ecotoxicology assay for the evaluation of environmental water quality in a tropical urban estuary
Abstract Most studies evaluating the impacts of river pollution in the semi-arid region of Brazil have been geared towards physiochemical analyses, and investigations of the adverse effects of water pollution on associated organisms are scarce. This study aimed to evaluate the water quality in the Poxim river estuary in Aracaju, Sergipe throughout the dry an

5. In vitro Evaluation of Oxidative Stress Caused by Fine Particles (PM2.5) Exhausted from Heavy-Duty Vehicles Using Diesel/Biodiesel Blends under Real World Conditions
In this work, the redox activity of fine diesel/biodiesel particulate matter (PM2.5) was studied in order to approach its toxicity from reactive oxygen species, due to adverse effects it may cause to human health. The oxidative potential was measured by the dithiothreitol (DTT) assay in order to study the relative contribution of water-soluble transition met

6. Physical training for asthma
BACKGROUND: People with asthma may show less tolerance to exercise due to worsening asthma symptoms during exercise or other reasons such as deconditioning as a consequence of inactivity. Some may restrict activities as per medical advice or family influence and this might result in reduced physical fitness. Physical training programs aim to improve physical

7. EFEITO in vitro DE Paullinia cupana NO METABOLISMO OXIDATIVO DE ESPERMATOZÓIDES HUMANOS EXPOSTOS AO CLORETO DE METILMERCÚRIO / EFFECT OF Paullinia cupana in vitro oxidative metabolism HUMAN SPERM EXPOSED TO CHLORIDE METHYLMERCURY
Investigations suggests that methylmercury (MeHg) toxicitiy is related to oxidative stress promotion caused by lipid peroxidation of cell membranes as well as genotoxicity. The methylmercury (MeHg) exposition causes production of adverse effects as deterioration of semen quality, testicular degeneration, and male reproductive failure. Since human sperm is a

8. Efeitos biomoleculares do JB-1 (um peptídeo análogo do IGF-1) em um modelo experimental de retinopatia induzida por oxigênio em ratos / Biomolecular effects of jb-1 (an igf-1 peptide analog) in a Rat model of oxygen-induced retinopathy
INTRODUCTION: Low serum insulin growth factor (IGF-1) levels at birth is a risk factor for the development of retinopathy of prematurity in extremely low birth weight infants. This may be due to its role as a permissive factor for vascular endothelial growth factor (VEGF) function in normal and pathologic vascular development. OBJECTIVE: To test the hypothes

9. Caracterização do módulo elástico por espectroscopia mecânica da liga Ti-13Nb-13Zr
In the present time the titanium and their alloys are begin widely studied in the field of biomaterials because of its suitable mechanical properties such as low elastic modulus, excellent corrosion resistance and high biocompatibility. Recent studies are being focused on alloys free of toxic elements as Al and V, which are contained in the alloy Ti-6Al-4V t

10. Papel dos leucócitos na fisiopatologia da anemia falciforme / Role of leukocytes in sickle cell anemia pathophysiology
Sickle Cell Disease (SCD) is a disorder of hemoglobin synthesis, caused by a point mutation, and resulting in the production of abnormal sickle hemoglobin, HbS. The consequence of low oxygen levels is HbS polymerization, which is responsible for the vaso-occlusive phenomenon that is the hallmark of the disease. SCD is a chronic inflammatory disease character

11. ProduÃÃo de Ãcido CÃtrico utilizando glicerol residual da produÃÃo de biodiesel como substrato / Production of citric acid using residual glycerol from biodiesel production as a substrate
Due to government financial incentives, which boost the production of biodiesel, there has been a large scale production of this fuel. However, this growth has proved to be exaggerated, rising a worrying factor: the destination of the glycerol excess from biodiesel production. Such concern is clearly shown to prove an important fact: for every ton of biodies

12. Avaliação dos efeitos de protocolos de manuseio mínimo em parâmetros fisiológicos de recém-nascidos pré-termo com doença de membrana hialina em ventilação mecânica
The literature recommends the practice of minimal handling during the first 72 hours of life to preterm newborn due to the risk of periventricular and intraventricular hemorrhage (PIVH) in the first days of life. However, there are few published studies that evaluate the effects of the use of minimal handling protocol in the group of preterm infants and the
