1. Evaluation of the cytotoxicity of polyurethane and non-latex orthodontic chain elastics
Allergy caused by latex proteins has been well documented. Thus, the study of non-latex materials, is necessary. The aim of this study is to evaluate the cytotoxicity of silver-coloured orthodontic chain elastics, of polyurethane and latex-free. Nine chain elastics from different manufactures (3 latex-free and 6 polyurethane) were divided into 9 groups of 10

2. Fontes de antioxidantes do cerrado brasileiro: citotoxicidade e fototoxicidade in vitro
Annona crassiflora (araticum), Eugenia dysenterica (cagaita) e Caryocar brasiliense (pequi) são frutas do segundo maior bioma brasileiro: o cerrado. Atualmente, o cerrado enfrenta duas realidades diferentes: 1) a grande possibilidade de produção de alimentos, sendo considerado o maior celeiro do mundo; e 2) a riquíssima biodiversidade recentemente descob

3. Flavins promote changes in the extracellular matrix, signal transduction, antioxidant enzymes and metalloproteinases during osteoblast differentiation / Flavinas promovem mudanças na matriz extracelular, vias de transdução de sinal, enzimas antioxidantes e metaloproteinases durante a diferenciação de osteoblastos
Riboflavin (Rb-Vitamin B2) is the precursor of essential flavocoenzymes, flavin mononucleotide (FMN) and flavin adenine dinucleotide (FAD). These coenzymes participate in numerous enzymatic processes dependent on electron transfer reactions that occur in energyproducing, biosynthetic, and detoxifying and electron-scavenging pathways. Increase dietary ribofla

4. Estudo in vitro da compatibilidade do osso bovino misto quimicamente tratado
Biomaterials have been developed and investigated aiming to help bone regeneration. Xenografts of bovine origin stand out due to their biocompatibility, low cost and availability. Some protocols have been tested to develop a chemically treated material containing the anorganic (hydroxiapatite) and the organic (collagen) components of bovine boned: the mixed

5. In vitro citotoxicity test as an alternative to in vivo Draize test for the evaluation of cosmetic / Teste de citotoxicidade in vitrocomo alternativa ao teste in vivode Draize na avaliação de produtos cosméticos
The procedures described by Draize are the basis of both ocular and cutaneous irritation tests and have been adopted internationally for in vivo evaluation of products and substances. However, they have been criticized for ethical reasons, due to their cruelty towards animals. Therefore, alternative methodologies are being studied to evaluate the toxicity of

6. Induction of Specific Cytotoxic Lymphocytes in Mice Vaccinated with Brucella abortus RB51
A safe, more sensitive, nonradioactive, neutral red uptake assay was adopted to replace the traditional 51Cr release assay for detection of Brucella-specific cytotoxic T lymphocyte (CTL) activity. Our studies indicated that Brucella abortus strain RB51 vaccination of mice induced specific CTLs against both strain RB51- and strain 2308-infected J774.A1 macrop

7. Validity of Eucaryote Inhibitors for Assessing Production and Grazing Mortality of Marine Bacterioplankton †
Application of eucaryote inhibitors to the estimation of production and grazing mortality of bacterioplankton was evaluated. Exposure to a range of concentrations of thiram, cycloheximide, and neutral red (0.4 to 210, 36 to 1,777, 4 to 346 μM, respectively) was 98 to 100% effective at inhibiting growth of a chrysomonad in culture. Exposure to colchicine and
