13. Semiconductor Nanocrystals-Reduced Graphene Composites for the Electrochemical Detection of Carbendazim
A new nanocomposite based on ZnCdTe semiconductor nanocrystals (NCs) synthesized in situ on reduced graphene oxide (rGO) was obtained. The heterostructure was characterized using UV-Vis emission and absorption spectroscopies, which provided evidences of the growth of the nanocrystals onto the rGO matrix. To evaluate the electrochemical performance, carbon pa

14. Standardization and quality assessment for clinical grade mesenchymal stem cells from human adipose tissue
Abstract Background Mesenchymal stem cells have immense potential in stem cell-based therapies, however there is a pre-requisite to develop a curative cell dose. Adipose tissue-derived mesenchymal stem cells are promising mainly due to their potential abundance, immunomodulatory effect and remarkable differentiation potential. Nevertheless, senescence may d

15. Progresso temporal da brusone do trigo em função do inóculo primário, da aplicação de fungicida e da resistência dos genótipos
RESUMO No Brasil, existem poucos estudos sobre a epidemiologia da brusone do trigo, consequentemente, pouca informação tem sido gerada sobre o progresso da doença. Este estudo avaliou o progresso temporal da brusone do trigo em quatro genótipos, submetidos ao controle químico e a diferentes quantidades de inóculo primário de Pyricularia textomediogram

16. Increased serum gastrin in patients with different clinical forms of Chagas disease coinfected with Helicobacter pylori
ABSTRACT Trypanosoma cruzi and Helicobacter pylori (HP) are pathogens that cause chronic diseases and have been associated with hypergastrinemia. The aim of this study was to evaluate the fasting gastrin levels in patients with different clinical forms of Chagas disease (CD), coinfected or not by HP. The enrolled individuals were outpatients attending at the

17. Potencial de transmissão de Pyricularia graminis-tritici planta-semente e semente-plântula em genótipos de trigo com graus diferentes de resistência a brusone
Resumo: Estudos da transmissão de Pyricularia graminis-tritici pela semente de trigo podem auxiliar no estabelecimento de padrões de tolerância do patógeno na cultura. Quatro genótipos diferentes quanto à reação à brusone foram inoculados com cinco volumes da suspensão fúngica (1,5x105 esporos.mL-1), de modo a obter 0, 5, 10, 20 e 30% de plantas i

18. Isolamento, cultura e caracterização de células tronco mesenquimais multipotentes provenientes do sangue do cordão umbilical caprino
RESUMO: As células tronco mesenquimais (MSC) residem em pequenas quantidades em muitos tecidos e órgãos adultos, desempenhando um papel ativo na homeostase destes locais. O isolamento de MSC já foi demonstrado em amostras de medula óssea, tecido adiposo e fluido amniótico de cabras. O sangue de cordão umbilical é considerado uma fonte importante dess

19. Analysis of various potential prognostic markers and survival data in clear cell renal cell carcinoma
ABSTRACT Purpose Clear cell renal cell cancers frequently harbor Von Hippel-Lindau gene mutations, leading to stabilization of the hypoxia-inducible factors (HIFs) and their target genes. In this study, we investigated the relationship between vascular endothelial growth factor (VEGF), HIF-1α, HIF-2α, p53 positivity, microvessel density, and Ki-67 rates

20. Evolution of hepatitis B serological markers in HIV coinfected patients: a case study
ABSTRACT OBJECTIVE To describe the evolution of serological markers among HIV and hepatitis B coinfected patients, with emphasis on evaluating the reactivation or seroreversion of these markers. METHODS The study population consisted of patients met in an AIDS Outpatient Clinic in São Paulo State, Brazil. We included in the analysis all HIV-infected and

21. Goat umbilical cord cells are permissive to small ruminant lentivirus infection in vitro
Abstract Small ruminant lentiviruses isolated from peripheral blood leukocytes and target organs can be propagated in vitro in fibroblasts derived from goat synovial membrane cells. These cells are obtained from tissues collected from embryos or fetuses and are necessary for the establishment of the fibroblast primary culture. A new alternative type of host

22. Osteogenic potential of periodontal ligament stem cells are unaffected after exposure to lipopolysaccharides
Abstract Periodontitis develops as a result of a continuous interaction between host cells and subgingival pathogenic bacteria. The periodontium has a limited capacity for regeneration, probably due to changes in periodontal ligament stem cells (PDLSCs) phenotype. The aim of this study was to evaluate the effects of lipopolysaccharides from Porphyromonas gin

23. Immunohistochemical angiogenic biomarkers in hepatocellular carcinoma and cirrhosis: correlation with pathological features
OBJECTIVE To investigate immunohistochemical markers of angiogenesis and their association with pathological prognostic features in hepatocellular carcinoma and cirrhotic liver. METHODS Vascular endothelial growth factor, CD105, and cyclooxygenase-2 were immunohistochemically detected in 52 hepatocellular carcinoma tissue samples and 48 cirrhotic liver tis

24. Investigation of modified platelet-rich plasma (mPRP) in promoting the proliferation and differentiation of dental pulp stem cells from deciduous teeth
Stem cells from human exfoliated deciduous teeth (SHEDs) have great potential to treat various dental-related diseases in regenerative medicine. They are usually maintained with 10% fetal bovine serum (FBS) in vitro. Modified platelet-rich plasma (mPRP) would be a safe alternative to 10% FBS during SHEDs culture. Therefore, our study aimed to compare the pro
