13. Developments in the use of nanocapsules in oncology
The application of nanotechnology to medicine can provide important benefits, especially in oncology, a fact that has resulted in the emergence of a new field called Nanooncology. Nanoparticles can be engineered to incorporate a wide variety of chemotherapeutic or diagnostic agents. A nanocapsule is a vesicular system that exhibits a typical core-shell struc

14. Alelopatia e bioprospecção em Rapanea ferruginea e Rapanea umbellata
Allelopathy is a process that involves primary or secondary metabolites produced by plants and microorganisms, which influences the growth and development of agricultural and biological systems. The intensity of plant allelopathic effects may depend on the hábitat, age and the biotic and abiotic conditions during the seasons in which they were collected. Wh

15. Pharmaceutical use of galactomannans
The pharmaceutical use of galactomannans from different sources, commercial and noncommercial, has been extensively studied over the past decade. Galactomannans show potential in the global trend towards the use of more plant-based products for ecological motives, and their production and application do not cause pollution or disturb the ecosystem. There is

16. International partnership for rice improvement in Latin America: CIRAD, a case study.
In Latin America and the Caribbean (LAC), rice is an important staple food. A significant increase in rice production has bean achieved mainly through the release and adoption of high yielding varieties. during the last 40 years, about 300 varieties were released. They were developed by national and international rice research institutions. The Centre for In

19. Incorporação e liberação de resveratrol em hidrogéis poliméricos / Resveratrol immobilization and release in polymeric hydrogels
Resveratrol (3, 4, 5-trihydroxystilbene) is a polyphenolic produced by a wide variety of plants in response to injury and found predominantly in grape skins. This active ingredient has been shown to possess benefits for the health, such as the antioxidant capacity which is related to the prevention of several types of cancer and skin aging. However, the oral

20. Aplicação de ciclodextrinas em processos têxteis
Cyclodextrins (CDs) are water soluble cyclic sugars with a hydrophobic nanometric cavity that permits the formation of host/guest inclusion complexes with a large variety of molecules, alternating their physical-chemical properties. In the present review CD research related to the processing of textiles is revised and discussed. CDs may function as encapsula

21. Endossimbiose de Tetranychus evansi Baker e Pritchard (Acari: Tetranychidae) e a resposta de defesa induzida em tomateiro / Endosymbioses of Tetranychus evansi Baker and Pritchard (Acari: Tetranychidae) and tomato induced defence response
Interactions between arthropods and microorganisms have been receiving more attention due to the impact that these symbiotic associations causes on their macrosymbionts. Reproduction is the main biological parameters affected with cytoplasmic incompatibility and thelytokous parthenogenesis; however, endosymbionts can help arthropods to exploit host plants. I

22. Peptídeos antimicrobianos: síntese, ensaios biológicos, estudos termodinâmicos e análise estrutural por RMN em meios biomiméticos
Many organisms employ noxious chemicals (e.g., amines, steroid derivatives, alkaloids and peptides) to defend themselves against predators and pathogenic microrganisms. Among these chemical agents stand out peptides that can be found in a wide variety of organisms including bacteria, fungi, plants, insects, fish, amphibians,arachnids and mammals. The vast ma

23. Purine nucleotides reduce superoxide production by nitric oxide synthase in a murine sepsis model
Sepsis involves a systemic inflammatory response of multiple endogenous mediators, resulting in many of the injurious and sometimes fatal physiological symptoms of the disease. This systemic activation leads to a compromised vascular response and endothelial dysfunction. Purine nucleotides interact with purinoceptors and initiate a variety of physiological p

24. Oocyst wall formation and composition in coccidian parasites
The oocyst wall of coccidian parasites is a robust structure that is resistant to a variety of environmental and chemical insults. This resilience allows oocysts to survive for long periods, facilitating transmission from host to host. The wall is bilayered and is formed by the sequential release of the contents of two specialized organelles - wall forming b
