1. Validation of the Family Health Behavior Scale for the Brazilian population
Abstract Objective: To validate the Family Health Behavior Scale (FHBS) for Brazilian families. Methods: The sample included 272 children aged 5 to 12 years old. Caregivers and their healthy answered the FHBS and questions about physical activity. In addition, anthropometric measurements of the children’s weight and height were performed, as well as the

2. Elevated Lipoprotein(A) in Children and Adolescents: Early Identification is Key for Successful Intervention
The usefulness of molecularly imprinted polymer assisted paper spray ionization mass spectrometry (MIP-PSI-MS) for the determination of methamphetamine in urine has been demonstrated. MIP-PSI-MS is a method in which a MIP is synthesized on the surface of a paper, producing a chemically selective paper surface with molecular recognition sites for a target ana

3. In Vitro additive effect on griseofulvin and terbinafine combinations against multidrug-resistant dermatophytes
ABSTRACT Griseofulvin (GF) and terbinafine (TF) are commonly used drugs to treat dermatophytosis, a fungal infection of the skin. Today there is an increase in drug resistance to these antifungals which highlight the need for alternative synergistic therapies. Minimum Inhibitory Concentration (MIC) of GF and TF were determined against fungi clinical isolates

4. Study of Mechanical and Wear Behaviour of Hyper-Eutectic Al-Si Automotive Alloy Through Fe, Ni and Cr Addition
Effect of Fe, Ni and Cr addition on the wear behavior of hyper-eutectic Al-Si automotive alloy has been studied. Dry sliding wear tests have been conducted using pin-on-disc wear testing machine under normal loads of 20N and constant sliding speed of 0.64 ms-1. Influence of Fe addition to the base alloy increases the wear rate due to the formation of needle

5. Acoustic Emission Analysis of Cement Mortar Specimens During Three Point Bending Tests
Abstract This work discusses the experimental results of Acoustic Emission (AE) recordings during repetitive loading/unloading loops of cement mortar beams subjected to three point bending. Six repetitive loading cycles were conducted at a gradually higher load level until the failure of the specimens. The experimental results clearly show the existence and

6. Cat's claw oxindole alkaloid isomerization induced by common extraction methods
Cat's claw oxindole alkaloids are prone to isomerization in aqueous solution. However, studies on their behavior in extraction processes are scarce. This paper addressed the issue by considering five commonly used extraction processes. Unlike dynamic maceration (DM) and ultrasound-assisted extraction, substantial isomerization was induced by static maceratio

7. Estudo de mecanismos de deformação lenta da gipsita bandada da Chapada do Araripe em ensaios de fluência monitorados por emissão acústica / Study of slow deformation mechanisms of the banded gypsum rock of the Chapada do Araripe in creep tests monitored by acoustic emission
Experimental studies by several authors have shown some of the key deformation mechanisms in gypsum, such as plastic flow and pressure dissolution. Even so, there is still sparse knowledge about the mechanical behavior of natural gypsum rocks. Creep mechanisms of the banded gypsum rock of Santana Formation from the Chapada do Araripe (Santana Formation) in c

8. Estudos de RMN de 1H e de 13C de derivados da 1,7,7-trimetilbiciclo [2.2.1] heptano-2-ona 3-substituida
This work aimed to evaluate the empirical substituents effects on the Carbon-13 chemical shifts of 3-substituted 1,7,7 -trimethylbicyclo[2.2.1]heptan-2-one derivatives (or 3-substituted camphor) and their contingent dependence on electronic and steric transmission mechanisms. A literature survey had shown that, besides other things, there was controversy on

9. Light-Dark Regulation of Starch Metabolism in Chloroplasts: II. Effect of Chloroplastic Metabolite Levels on the Formation of ADP-Glucose by Chloroplast Extracts 1
The rate of ADP-glucose formation from [14C]glucose 6-phosphate and ATP by the soluble fraction of lysed chloroplasts is studied as a function of the levels of metabolites (3-phosphoglycerate, orthophosphate, hexose monophosphate, and ATP) as determined in whole chloroplasts of Spinacia oleracea in light and dark.

10. Effect of mechanical removal of pili on gliding motility of Myxococcus xanthus.
Gliding motility of Myxococcus xanthus is governed by both the adventurous (A) and the social (S) motility gene systems. The presence of pili has previously been shown to be correlated with a genetically intact S-motility system (D. Kaiser, Proc. Natl. Acad. Sci. USA 76:5952-5956, 1979). The purpose of the present work was to study the direct effect of mecha

11. EFFECT OF D2O ON THE CARBOXYPEPTIDASE-CATALYZED HYDROLYSIS OF O-(trans-CINNAMOYL)-L-β-PHENYLLACTATE AND N-(N-BENZOYLGLYCYL)-L-PHENYLALANINE*
Solvent isotope effects have been examined for the action of the zinc-containing metalloenzyme carboxypeptidase A on ester and peptide substrates. The kinetic parameters for the carboxypeptidase-catalyzed hydrolysis of an ester, O-(trans-cinnamoyl)-L-β-phenyllactate, in 0.05 M Tris-DCl buffer containing 0.5 M NaCl at pD 8.07 and 25° were compared with thos

12. Purification of the bacteriocin bavaricin MN and characterization of its mode of action against Listeria monocytogenes Scott A cells and lipid vesicles.
Bavaricin MN was purified from Lactobacillus sake culture supernatant 135-fold with a final yield of 11%. Sequence analysis revealed bavaricin MN to be a 42-amino-acid peptide having a molecular weight of 4,769 and a calculated pI of 10.0. Computer analysis indicated that the C-terminal region may form an alpha-helical structure with an amphipathic nature de
