2. Psychometric properties of the modified Yale Food Addiction Scale 2.0 in a large Brazilian sample
Objective: The field of food addiction has attracted growing research attention. The modified Yale Food Addiction Scale 2.0 (mYFAS 2.0) is a screening tool based on DSM-5 criteria for substance use disorders. However, there is no validated instrument to assess food addiction. Methods: The mYFAS 2.0 has been transculturally adapted to Brazilian Portuguese.

4. O efeito de estados de estrutura alfa no espalhamento 16O+12C e na reação de captura astrofísica 12C()16O / Effect of alfa states in the 16O+12C scattering and in the 12C+alfa, 8)16O capture reaction of astrophysical interest
Neste trabalho, investigou-se o espalhamento elástico 16O+12C, considerando o efeito da troca de uma partícula alfa entre o projétil e o alvo que conduz aos mesmos núcleos do canal de entrada (transferência elástica). Foram analisadas distribuições angulares em uma faixa de energias que, no referencial de centro de massa, vai de 8,55 MeV até 56,57 M

5. Crenças e atitudes sobre epilepsia infantil adaptação transcultural do instrumento the epilepsy beliefs and attitudes scale
The childhood epilepsy is a chronic neurological disorder, most common in childhood, associated with profound psychosocial limitations in daily life in epileptic children. These limitations may be related to the characteristics of the disease as the age of onset, severity and type of epilepsy and the lack of information that is still as one of the factors th

6. Validation of the Social Phobia and Anxiety Inventory for Children (SPAI-C) in a sample of Brazilian children
The purpose of the present study was to examine the factor structure and psychometric properties of the Social Phobia and Anxiety Inventory for Children (SPAI-C), an instrument developed in the United States and applied to a sample of Brazilian schoolchildren. The process included the translation of the original material from English into Portuguese by two b

7. Effect of urea on bovine serum albumin in aqueous and reverse micelle environments investigated by small angle X-ray scattering, fluorescence and circular dichroism
The influence that urea has on the conformation of water-soluble globular protein, bovine serum albumin (BSA), exposed directly to the aqueous solution as compared to the condition where the macromolecule is confined in the Aerosol-OT (AOT - sodium bis-2-ethylhexyl sulfosuccinate)/n-hexane/water reverse micelle (RM) is addressed. Small angle X-ray scattering

8. Factor structure of Bech's version of the Brief Psychiatric Rating Scale in Brazilian patients
The objective of the present study was to evaluate the factor structure of Bech's version of the Brief Psychiatric Rating Scale (BPRS), translated into Portuguese. The BPRS was administered to a heterogeneous group of psychiatric inpatients (N = 98) and outpatients (N = 62) in a University Hospital. Each patient was evaluated from one to eight times. The int

9. Glycosylation and structure of the yeast MF alpha 1 alpha-factor precursor is important for efficient transport through the secretory pathway.
The MF alpha 1 gene encodes a precursor, prepro-alpha-factor, that undergoes several proteolytic processing steps within the classical secretory pathway to produce the mature peptide pheromone, alpha-factor. To investigate the role of structural features of the MF alpha 1 precursor in alpha-factor production, we analyzed the effect of mf alpha 1 mutations th

10. Different structure-function relationships for alpha-factor-induced morphogenesis and agglutination in Saccharomyces cerevisiae.
Eight synthetic analogs of the mating pheromone alpha-factor-induced morphogenesis and increased agglutinability in a cells. Most analogs induced increased agglutinability at lower concentrations than those at which they induced morphogenesis, but the ratio of the potencies for the two effects varied 140-fold among different analogs. Morphological response t

11. Structure of cell wall mannan of Candida kefyr IFO 0586.
We conducted a structural analysis of the antigenic cell wall mannoprotein (mannan) isolated from Candida kefyr (formerly Candida pseudotropicalis) IFO 0586. The result of two-dimensional homonuclear Hartmann-Hahn analysis of this mannan indicates that the molecule is constructed from alpha-1,2- and alpha-1,6-linked mannopyranose residues. Upon alkali treatm

12. Three-dimensional crystal structure of recombinant murine interferon-beta.
The crystal structure of recombinant murine interferon-beta (IFN-beta) has been solved by the multiple isomorphous replacement method and refined to an R-factor of 20.5% against 2.6 A X-ray diffraction data. The structure shows a variant of the alpha-helix bundle with a new chain-folding topology, which seems to represent a basic structural framework of all
