13. TNF-alpha increases angiogenic potential in a co-culture system of dental pulp cells and endothelial cells
Abstract We recently demonstrated that a co-culture system of human umbilical vein endothelial cells (HUVECs) and human dental pulp stem cells (hDPSCs) could enhance angiogenesis ability in vitro. However, whether tumor necrosis factor α (TNF-α) could promote blood vessel formation during pulp regeneration remained unknown. The aim of this study was to inv

14. Linear Peptide Analogues from Jatropha’s Orbitides Promote Migration of Human Neonatal Foreskin Fibroblasts in vitro and Collagen Deposition
Orbitides are a class of small naturally occurring cyclic peptides with structural and functional diversities. Their chemical properties make this class feasible to be obtained by solid phase peptide synthesis (SPPS). Therefore, this synthetic accessibility enables useful application and facilitates the identification of analogues, bioactivity studies, and t

15. The Age of Migration Crisis
Resumo: O artigo analisa as transformações históricas na formulação de políticas migratórias entre os séculos XIX e XXI, sintetizando a emergência de uma “era da crise migratória”. A primeira seção discute por que a migração internacional constitui um problema para as concepções políticas dos Estados nacionais. A segunda seção enfatiza

16. Genetic diversity of Echinococcus vogeli in the western Brazilian Amazon
Human polycystic echinococcosis is a parasitic infection caused by the larval stage of Echinococcus vogeli, which occurs in rural areas of Central and South America. Until now, little information on the genetic variability of E. vogeli is available. Here, 32 samples from human-excised E. vogeli cysts had a 396-bp sequence of the mitochondrial cytochrome oxid

17. Cross-border healthcare and prognosis of HIV infection in the triple border Brazil-Paraguay-Argentina
Resumo: O ato de atravessar uma fronteira internacional para receber cuidados de saúde é uma realidade nas áreas fronteiriças. O fluxo tende a ser em direção à cidade com os melhores recursos humanos e melhor infraestrutura em saúde. Embora sejam conhecidos os fatores prognósticos relacionados à infecção pelo HIV, o valor prognóstico desse tipo

18. Ecologia, doença e desenvolvimento na Amazônia dos anos 1950: Harald Sioli e a esquistossomose na Fordlândia
Resumo O artigo trata dos estudos do biólogo alemão Harald Sioli sobre a esquistossomose na região de Fordlândia, às margens do rio Tapajós, no Pará, realizados no início dos anos 1950, quando integrou a equipe do Instituto Agronômico do Norte (IAN). O IAN foi criado em 1939, no bojo de uma série de iniciativas destinadas a promover o desenvolvimen

19. Curcumin combining with si-MALAT1 inhibits the invasion and migration of colon cancer SW480 cells
To study the effect of small interfering RNA targeting metastasis-associated lung adenocarcinoma transcript1 (si-MALAT1) combining with curcumin on the invasion and migration abilities of human colon cancer SW480 cells, and to explore the involved molecular mechanism. The recombinant lentiviral vector expressing si-MALAT1 was constructed, and its titer was d

20. Imported malaria in Rio de Janeiro state between 2007 and 2015: an epidemiologic approach
Imported malaria is a malaria infection diagnosed outside the area where it was acquired and is induced by human migration and mobility. This retrospective study was performed based on secondary data from 2007 to 2015. In total, 736 cases of imported malaria (79.7% of 923 cases) were recorded in Rio de Janeiro state. Of the imported cases, 55.3% came from ab

21. Effects of Calcium Hypochlorite and Octenidine Hydrochloride on L929 And Human Periodontal Ligament Cells
Resumo Para a seleção do irrigante endodôntico deve-se considerar os possíveis efeitos citotóxicos. O objetivo foi avaliar os efeitos do hipoclorito de cálcio [Ca(OCl)2] e do cloridrato de octenidina (OCT) em células L929 e do ligamento periodontal humano (hPDL). As células foram expostas a diferentes doses das soluções: Ca(OCl)2 2,5% e 5%, OCT 0,1

22. Benzyl isothiocyanate inhibits invasion and induces apoptosis via reducing S100A4 expression and increases PUMA expression in oral squamous cell carcinoma cells
Benzyl isothiocyanate (BITC) has been shown to inhibit invasion and induce apoptosis of various types of cancer. However, its role on human oral squamous cell carcinoma (OSCC) cells is still not well elucidated. In the present study, we investigated the effect of BITC on apoptosis and invasion of SCC9 cells, and its underlying mechanisms in vitro and in vivo

23. Differential expression of microRNA-411 and 376c is associated with hypertension in pregnancy
Preeclampsia is a major reason of morbidity and mortality in pregnant women and perinatal fetus. Hence, it is of prime importance that diagnostic markers are defined to predict chances of preeclampsia in pregnant women. It has been previously shown that microRNA (miRNA)-376c expression is decreased in the placenta of preeclampsia patients at term. Even thoug

24. Synthesis of Nerol Derivatives Containing a 1,2,3-Triazole Moiety and Evaluation of Their Activities against Cancer Cell Lines
In the present investigation, a collection of twenty two nerol derivatives, containing 1,2,3-triazolic appendages, was synthesized and screened in vitro for their cytotoxic activity against HL60, Nalm6, and Jurkat human leukemia cells as well as against B16F10 (melanoma cell line). In most cases, derivatives were able to reduce cell viability. The most poten
