13. Aspects of Langerhans cells and TNF-α in the cutaneous immunity of anogenital warts,
Abstract Background: Anogenital warts are the leading sexually transmitted infection in patients seeking care at specialized clinics. They may display a vast array of forms, according to the interaction of the virus with the host's immunity. Cellular immunity is the epithelium's main form of defense against the virus, involving an active participation of th

14. Engineered scPDL1-DM1 drug conjugate with improved in vitro analysis to target PD-L1 positive cancer cells and intracellular trafficking studies in cancer therapy
Abstract Antibody-drug conjugates (ADC), precisely deliver a cytotoxic agent to antigen-expressing tumor cells by using specific binding strategies of antibodies. The ADC has shown the ability of potent bio-therapeutics development but indefinite stoichiometric linkage and full-length antibody penetration compromised the field of its advancement. Single chai

15. Atomic force microscopy evidences of bacterial cell damage caused by propolis extracts on E. coli and S. aureus
Abstract The interaction of the aqueous extract of green propolis with the bacterial envelope was investigated using atomic force microscopy on E. coli and S. aureus, as Gram-negative and Gram-positive model microorganisms. The bacteria were incubated in the extracts with variable proportions of water/ethanol, i.e., in different concentrations of total pheno

17. Identification of the molecular mechanisms associated with acute type A aortic dissection through bioinformatics methods
Aortic dissection is characterized by the redirection of blood flow, which flows through an intimal tear into the aortic media. The purpose of this study was to find potential acute type A aortic dissection (AAAD)-related genes and molecular mechanisms by bioinformatics. The gene expression profiles of GSE52093 were obtained from Gene Expression Omnibus (GEO

18. Campylobacter jejuni and Campylobacter coli originated from chicken carcasses modulate their transcriptome to translate virulence genes in human cells
RESUMO: O objetivo foi determinar a disseminação de perfis geneticamente semelhantes de Campylobacter em carcaças de frango e avaliar sua capacidade de produzir transcritos para os genes ciaB, dnaJ, p19 e sodB, antes e após o cultivo em células Caco-2. As cepas utilizadas foram isoladas de 420 amostras de carcaças de frango resfriadas e congeladas pron

19. Metabolism of carbohydrates in Estilosantes cv. Campo Grande under different systems of cultivation and nitrogen fertilization
ABSTRACT. The objective of this study was to verify the activity of invertases in Estilosantes under the influence of cultivation systems and nitrogen fertilization in two seasons. The experiment was conducted in the Xaraés area, where Estilosantes was planted according to a 2 x 2 factorial scheme with two cultivation systems (monoculture and mixed pasture)

20. BINARY CO-CULTURE SELECTION FROM MARINE-DERIVED MICROORGANISMS FOR DIFFERENTIAL PRODUCTION OF SPECIALIZED METABOLITES
Nowadays the discovery of new compounds from microorganisms has substantially decreased. Genomic studies have shown that certain genes are not expressed under standard laboratory conditions. In order to overcome this problem, several methods including microorganism co-culture have been developed. The aim of this work was to select binary co-cultures of marin

21. Endophytic interaction of Bacillus sp. in micropropagated banana plantlets
Abstract: The banana tree is associated with different species of endophytic bacteria that can stimulate plant growth. However, further studies are needed to better understand the relationships between this group of bacteria and the host plant. The objective of this study was to investigate the localization of the EB-40 (Bacillus sp.) through anatomical and

22. Variability in the virulence of specific Mycobacterium tuberculosis clinical isolates alters the capacity of human dendritic cells to signal for T cells
BACKGROUND Once in the pulmonary alveoli, Mycobacterium tuberculosis (Mtb) enters into contact with alveolar macrophages and dendritic cells (DCs). DCs represent the link between the innate and adaptive immune system owing to their capacity to be both a sentinel and an orchestrator of the antigen-specific immune responses against Mtb. The effect that the v

23. Food insecurity and social support in families of children with sickle-cell disease,
Resumo Objetivo: Avaliar as associações entre insegurança alimentar (IA) e apoio social em famílias de crianças com doença falciforme (DF). Métodos: Estudo transversal feito com as famílias de 190 crianças, de cinco a nove anos, atendidas em um hospital de referência em hematologia no Estado do Rio de Janeiro. A IA foi medida com a escala brasile

24. Composite-derived monomers affect cell viability and cytokine expression in human leukocytes stimulated with Porphyromonas gingivalis
Abstract Objectives: Dental composites release unreacted resin monomers into the oral environment, even after polymerization. Periodontal cells are, therefore, exposed to substances that potentially elicit the immune inflammatory response. The underlying molecular mechanisms associated with the interaction between resin monomers and human immune cells found
