Abordagens inovadoras para o desenvolvimento de vacinas
(Universidade Federal de São Paulo, 2021-01-29)O sistema imunológico é capaz de eliminar corpos estranhos, como patógenos, para manter a homeostasia do corpo. Contudo, alguns desses patógenos são capazes de escapar dos mecanismos das respostas imunológicas. Por isso, ... -
Biogenic nanoparticles: copper, copper oxides, copper sulphides, complex copper nanostructures and their applications
(Springer, 2013-09-01)Copper nanoparticles have been the focus of intensive study due to their potential applications in diverse fields including biomedicine, electronics, and optics. Copper-based nanostructured materials have been used in ... -
Characterization and evaluation of free and nanostructured ursolic acid incorporated in cosmetic formulation using thermal analysis
(Springer, 2014-03-01)The ursolic acid (UA) increases the skin's barrier function and acts in epidermal differentiation of keratinocytes in the epidermis, promoting cell renewal. Besides the mentioned properties UA also has antioxidant, ... -
Correlation between degree of crystallinity, morphology and mechanical properties of pps/carbon fiber laminates
(Univ fed sao carlos, dept engenharia materials, 2016)The crystallization degree in semi-crystalline thermoplastics plays an important role in determining the final properties of structural composite material (e.g. toughness, stiffness and solvent resistance). The main purpose ... -
Estudo da termodifusão e efeitos fototérmicos em nanopartículas metálicas e bimetálicas
(Universidade Federal de São Paulo, 2016-11-11)In this work, iron oxide nanoparticles (NPs) coated with several ligands and bimetallic NPs (Fe and Au) were produced following three methodologies: co-precipitation of iron salts, thermal decomposition of coordination ... -
Estudo Das Biointerações De Nanopartículas De Ouro Ultrapequenas: Influência Do Tamanho E Revestimento De Superfície Dissertação
(Universidade Federal de São Paulo (UNIFESP), 2017-03-31)Thus, it is possible to control the size, shape and surface chemistry of nanomaterials, aiming stable and inert structures, or even aiming to regulate the interactions of nanomaterials with proteins and cells. For example, ... -
Estudo de compósitos formados a partir de nanopartículas de fluoreto de lantânio
(Universidade Federal de São Paulo, 2015-10-16)The combination of materials to form hybrids with unique properties, different from those of the isolated components, is a strategy used to prepare functional materials with improved properties aiming to allow their ... -
Estudo de filmes híbridos de celulose e polímeros sintéticos para imobilização de nanopartículas de prata
(Universidade Federal de São Paulo, 2018-06-27)Microcrystalline cellulose and hydropropylmethylcellulose (HPMC) films, added with two synthetic polymers, polyvinylalcohol (PVA) and polyvinylpyrrolidone (PVP), were produced on the present study. The aim of PVA and PVP ... -
Estudo Prospectivo De Fase 1/2 Para Avaliação Da Maior Dose Tolerável, Toxicidade, Farmacocinética E Eficácia Do Lde-Etoposide No Condicionamento Do Transplante Alogênico De Células-Tronco Hematopoeticas De Pacientes Com Leucemia Mieloide Aguda Recaída / Refratária
