1. Properties of Cu-Co Composite Catalysts for Synthesis of Aliphatic Alcohols
Cu-Co-containing cellulose-based carbon composite materials (Cu-Co/Cel) were formed by a matrix isolation method. Using X-ray diffraction (XRD), transmission electron microscopy (TEM), infrared-Fourier spectroscopy (IR-Fourier spectroscopy), and non-isothermal research methods, the physicochemical properties of the composites were established. The catalysts

2. Isolation, characterisation and continuous culture of Lactobacillus spp. and its potential use for lactic acid production from whey
Abstract Bioprospecting of microorganisms with the potential of exploiting agro-industrial wastes is an active field of biotechnological research. In this study, we aimed to isolate a microorganism adapted to the dairy matrix with specific characteristics to produce lactic acid from dairy industry wastes, such as whey. Whey was collected from the agricultura

4. O BARULHO INAUDÍVEL: ADOLESCÊNCIA, TÉDIO E RETRAIMENTO
RESUMO: Este artigo tem como objetivo refletir acerca da não comunicação reativa - conceito desenvolvido por D. W. Winnicott, que corresponde a uma reclusão patológica. Para tanto, traz o relato do atendimento psicanalítico a um adolescente que apresentava um estado de isolamento. O artigo se reporta ao modo de funcionamento psicopatológico apresentad

5. Isolation and characterization of a human cementocyte-like cell line, HCY-23
Abstract Cementum is the mineralized tissue covering the tooth root that functions in tooth attachment and post-eruptive adjustment of tooth position. It has been reported to be highly similar to bone in several respects but remains poorly understood in terms of development and regeneration. Here, we investigate whether cementocytes, the residing cells in ce

6. A Balanced-to-Single-Ended Wilkinson Power Divider
Abstract A balanced-to-single-ended (BTSE) Wilkinson power divider of planar microstrip structure is proposed in this paper. It has a balanced input and two single-ended outputs. Cascade of a balun and a conventional power divider can be replaced by this proposed structure. Based on the theory of mixed-mode S parameters and the admittance matrix method, the

7. Avian Communities in the Amazonian Cangas Vegetation: Biogeographic Affinities, Components of Beta-Diversity and Conservation
ABSTRACT The Amazonian cangas is a vegetation type distributed as patches of open vegetation embedded in a matrix of tropical forest and that grows over iron-rich soils in the Serra dos Carajás region. To characterize cangas avifauna, we surveyed birds in eight patches varying from 43 to 1,366 hectares. Cangas avifauna has compositional affinities with sava

8. Isolation of biologically active peptides from the venom of Japanese carpenter bee, Xylocopa appendiculata
Abstract Background Mass spectrometry-guided venom peptide profiling is a powerful tool to explore novel substances from venomous animals in a highly sensitive manner. In this study, this peptide profiling approach is successfully applied to explore the venom peptides of a Japanese solitary carpenter bee, Xylocopa appendiculata (Hymenoptera: Apoidea: Apida

9. Floristic and ecological characterization of habitat types on an inselberg in Minas Gerais, southeastern Brazil
ABSTRACT Inselbergs are granitic or gneissic rock outcrops, distributed mainly in tropical and subtropical regions. They are considered terrestrial islands because of their strong spatial and ecological isolation, thus harboring a set of distinct plant communities that differ from the surrounding matrix. In Brazil, inselbergs scattered in the Atlantic Forest

10. Isolation of Tiliroside from Spiranthera odoratissima as Inhibitor of Trypanosoma cruzi Glyceraldehyde-3-phosphate Dehydrogenase by Using Bioactivity-Guided Fractionation
Glyceraldehyde-3-phosphate dehydrogenase (GAPDH) is a key enzyme involved in the Trypanosoma cruzi glycolytic pathway, parasite that causes Chagas' disease. There are only few drugs available to treat this disease, most of which present strong side effects. Natural products constitute a prime source for the discovery of new scaffolds potentially useful for t

11. PF/CLAY hybrid materials: a simple method to modulate the optical properties
Abstract The aim of this work was modulate the emission properties and improve thermal stability of a conjugated polymer incorporated into an inorganic matrix. Hybrid material was prepared based on poly(9,9-dioctylfluorene-co-phenylene (PF) and montmorillonite (Na+Mt) clay using wet impregnation of 10, 30 and 50 wt.% of PF into Na+Mt and Na+Mt intercalated w

12. Influence of microbiome species in hard-to-heal wounds on disease severity and treatment duration
ABSTRACT BACKGROUND: Infections, mostly those associated with colonization of wound by different pathogenic microorganisms, are one of the most serious health complications during a medical treatment. Therefore, this study is focused on the isolation, characterization, and identification of microorganisms prevalent in superficial wounds of patients (n = 50
