1. Stabilization effect of kraft lignin into PBAT:Thermal analyses approach
ABSTRACT Sterically hindered phenols are an important class of synthetic antioxidants for polymers, commonly incorporated to inhibit polyolefins or polyesters oxidation. However, synthetic antioxidants use is under restricted regulation due to their potential health risk and environmental impacts. Thus, great interest has been attracted to the phenol-based n

2. Extraction of matrine from Sophora flavescens Ait. and evaluation of its inhibitory effects on human nasopharyngeal carcinoma CNE-2 cells
Abstract The present study investigated the extraction and purification technology of matrine from Sophora flavescens Ait. and the inhibitory effects of matrine on human nasopharyngeal carcinoma (NPC) CNE-2 cells. The matrine was extracted from Sophora flavescens Ait. by decocting using ethanol-aqueous solution as the solvent, followed by purification using

3. Dependencia térmica de la salamandra endémica de Colombia Bolitoglossa ramosi (Caudata, Plethodontidae)
ABSTRACT Environmental temperature is a determining factor in the physiological and behavioral processes of amphibians because they are ectotherms and consequently depend on external heat sources to achieve optimal body temperatures. The aim of this study was to determine the thermal dependence of the Colombian endemic salamander Bolitoglossa ramosi Brame &

4. Algoritmos para o planejamento da operação de sistemas modernos de distribuição de energia elétrica = : Algorithms for operation planning of modern electric distribution power systems / Algorithms for operation planning of modern electric distribution power systems
The distribution system operation planning stage is concerned with the determination of capacitor bank, transformer and voltage regulator settings. This must be accomplished considering active and reactive power injections of distributed generators and at the main substation, as well as physical and regulatory issues in order to improve the network performan

5. Optimal regulation of oil fields under asymmetric information
Neste trabalho é analisada a relação entre um regulador e uma empresa petrolífera. Há várias incertezas inerentes à essa relação e o trabalho se concentra nos efeitos da assimetria de informação. Fazemos a caracterização da regulação ótima sob informação assimétrica, quando o regulador deve desenhar um mecanismo que induz a firma a revelar

6. Avaliação da deflexão elástica de fios ortodônticos de níquel-titânio, calibre 0,014 / Load-deflection study of caliber 0.014 nickel-titanium orthodontic wires
OBJECTIVE: The purpose of this study was to present the magnitude and the constancy of the forces released by nickel-titanium orthodontic wires, used to treat dental crowding. Another purpose was to compare the most usual types of bending tests used to evaluate these wires: 3-point test and clinical simulation device. MATERIAL AND METHODS: Eleven groups of o

7. Differential gene expression between wild-type and Gulo-deficient mice supplied with vitamin C
The aim of this study was to test the hypothesis that hepatic vitamin C (VC) levels in VC deficient mice rescued with high doses of VC supplements still do not reach the optimal levels present in wild-type mice. For this, we used a mouse scurvy model (sfx) in which the L-gulonolactone oxidase gene (Gulo) is deleted. Six age- (6 weeks old) and gender- (female

8. Physiological implications of the regulation of vacuolar H+-ATPase by chloride ions
Vacuolar H+-ATPase is a large multi-subunit protein that mediates ATP-driven vectorial H+ transport across the membranes. It is widely distributed and present in virtually all eukaryotic cells in intracellular membranes or in the plasma membrane of specialized cells. In subcellular organelles, ATPase is responsible for the acidification of the vesicular inte

10. Análise da expressão gênica no dermatófito Trichophyton rubrum mimetizando a infecção in vitro: pH e diferentes fontes de carbono regulando genes / Analysis of gene expression in the dermatophyte Trichophyton rubrum during the mimetic infection in vitro: pH and carboun sources are regulating genes
Dermatophytes are a group of fungi filamentous that have the ability to invade keratinized substrates, causing dermatophytosis in humans and animals and only penetrate deeper if the host is immunocompromised. Trichophyton rubrum is an anthropophilic and cosmopolitan fungi, the most common agent of superficial mycoses, which uses cell components such as prote

12. Analysis of genomic sequence features related to alternative splicing events (intron retention) in the human transcriptome / Análise de características das seqüencias genômicas relacionadas a eventos de splicing alternativo do tipo retenção de intron no transcriptoma humano
Most eukaryotic genes are split in exons and introns, requiring mRNA processing to remove intervening sequences and join exons (splicing). Exon/intron borders are defined by splice sites that are normally recognized with high fidelity, yielding the same processed mRNA each time. Notwithstanding such precise recognition, alternative joining of exons has been
