1. Dextran Sulfate/Pramlintide Polyelectrolyte Nanoparticles as a Promising Delivery System: Optimization, Evaluation of Supramolecular Interactions and Effect on Conformational Stability of the Peptide Drug
In this study, we investigated the feasibility to obtain nanoparticles (NPs) by assembling pramlintide (Pram) with dextran sulfate (DexS), as a new approach for mucosal peptide delivery. DexS/Pram NPs were prepared by dropwise addition of a Pram solution to a DexS solution under magnetic stirring. The physicochemical characteristics of NPs and molecular inte

2. Genetic parameters and selection of macaw palm (Acrocomia aculeata) accessions: an alternative crop for biofuels
Abstract This study aimed to estimate the parameters related to the genetic control of the physical characteristics of the fruits, oil content, and oil yield, and to proceed with the selection of macaw palm accessions. Forty-four macaw palm accessions of the active germplasm collection of the Federal University of Viçosa were collected for the evaluation of

3. Soils Developed on Geomorphic Surfaces in the Mountain Region of the State of Rio de Janeiro
ABSTRACT: The evaluation of soils in representative landscapes constitutes an opportunity to evaluate spatial distribution, discuss formation processes, and apply this knowledge to land use and management. In this sense, from the perspective of an environmentally diversified region, the aim of the present study is to evaluate the occurrence and understand th

4. Biochemical and physical kernel properties of a standard maize hybrid in different TopCross™ Blends
ABSTRACT A pilot experiment was undertaken in order to examine high oil populations of maize (Zea mays L.) to be used as pollinators in TopCross blends with commercial ZP341 standard hybrid. Five high oil populations (HOPs) from the Maize Research Institute (MRI) gene bank were chosen for this research, according to their high grain oil content, synchrony be

5. Effect of Ferrite on the Precipitation of σ Phase in Cast Austenitic Stainless Steel Used for Primary Coolant Pipes of Nuclear Power Plants
The effect of ferrite phase on the precipitation of σ phase in a Z3CN20.09M cast austenitic stainless steel (CASS) used for primary coolant pipes of pressurized water reactor (PWR) nuclear power plants was investigated by using isothermal heat-treatment, optical microscopy (OM), transmission electron microscopy (TEM) and electron probe microanalysis (EPMA)

6. Preparation and characterization of alginate and gelatin microcapsules containing Lactobacillus rhamnosus
ABSTRACT This paper describes the preparation and characterization of alginate beads coated with gelatin and containing Lactobacillus rhamnosus. Capsules were obtained by extrusion method using CaCl2 as cross linker. An experimental design was performed using alginate and gelatin concentrations as the variables investigated, while the response variable was t

7. Intranasal mucoadhesivemicroemulsion for neuroprotective effect of curcuminin mptp induced Parkinson model
ABSTRACT This study was to investigate the neuroprotective effect of curcumin against inflammation-mediated dopaminergic neurodegeneration in 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) mice model of Parkinson's disease (PD). Curcumin loaded sodium hyaluronate based mucoadhesive microemulsion (CMME) was developed by using Box Behnken design of Respon

8. NOVOS HÍBRIDOS BASEADOS EM OXIHIDRÓXIDO DE FERRO(III) E NANOPARTÍCULAS DE OURO (AuNPs/FeOOH) COMO CATALISADORES PARA A REDUÇÃO DE POLUENTES ORGÂNICOS AMBIENTAIS
A new δ-FeOOH supported nano-Au catalyst was prepared by a facile method using HAuCl4 as the gold source and NaBH4 as the reducing agent. The samples (denoted as AuNPs/FeOOH) were characterized by means of X-ray diffraction (XRD), UV-vis and infrared spectroscopies and scanning electron microscope (SEM). The obtained characterization data confirmed the form

9. Fast detection of deletion breakpoints using quantitative PCR
Abstract The routine detection of large and medium copy number variants (CNVs) is well established. Hemizygotic deletions or duplications in the large Duchenne muscular dystrophy DMD gene responsible for Duchenne and Becker muscular dystrophies are routinely identified using multiple ligation probe amplification and array-based comparative genomic hybridizat

10. Genetic diversity assessed by microsatellite markers in sweet corn cultivars
Information on genetic diversity is essential to the characterization and utilization of germplasm. The genetic diversity of twenty-two sweet corn cultivars (seventeen open-pollinated varieties, OPV, and five hybrids, H) was investigated by applying simple sequence repeat markers. A total of 257 primers were tested, of which 160 were found to be usable in te

11. UMA TEORÍA CAUSAL PARA LOS CASOS FREGE
Fodor argues for two theses that can be characterized as forming a dilemma: On one side, if we endorse a functional theory of concepts, we explain Frege cases in semantic terms but we cannot avoid semantic holism. On the other side, if we endorse a causal/informational approach, we avoid semantic holism but we cannot explain Frege cases in semantic terms. Fo
