ABSTRACT BACKGROUND: Package leaflets of medicines need to be intelligible, but tools for their evaluation are scarce. OBJECTIVE: To validate a new tool for assessing subjects’ satisfaction with medicine package leaflets (LiS-RPL). DESIGN AND SETTING: Cross-sectional descri...

Abstract Purpose Factor analysis is the most used tool in organizational research and its widespread use in scale validations contribute to decision-making in management. However, standard factor analysis is not always applied correctly mainly due to the misuse of ordinal data a...

ABSTRACT In this study, the influence of carcass parts weights (thigh, breast, wing, back weight, gizzard, heart, and feet) on whole carcass weight of white turkeys (Big-6) was analyzed by regression analysis based on ridge regression and factor analysis scores. For this purpose,...

The formation, crystallization and preliminary X-ray diffraction analysis of the tumour necrosis factor α (TNF)–tumour necrosis factor receptor type 2 (TNFR2) complex are described. The initial electron-density map, which was calculated using only the phases of refined TNF trimer...

Salmonella zuerich [1,9,27,(46)] has been shown to exhibit two levels of structural heterogeneity. The bacterium carries two distinct O-polysaccharide molecules with and without O:factor 1. Both sets of molecules (1+ and 1-) carry the two O:factors 27 and 46 on the same O chain, ...

We previously identified two genes, mfm1 and mfm2, with the potential to encode the M-factor mating pheromone of the fission yeast Schizosaccharomyces pombe (J. Davey, EMBO J. 11:951-960, 1992), but further analysis revealed that a mutant strain lacking both genes still produced ...

ABSTRACT. This study was realized to evaluate the monthly production, composition and quality of milk (total and defatted dry extract, lactose, fat and protein) and their relation to somatic cell count (SCC) and total bacterial count (TBC) using multivariate statistical analyses....

The analysis of regulatory regions in genome sequences is strongly based on the detection of potential transcription factor binding sites. The preferred models for representation of transcription factor binding specificity have been termed position-specific scoring matrices. JASP...

The Factor VIII antigen molecules in the plasma of patients with classical type 1 and variant type 2A von Willebrand disease were compared to the Factor VIII antigen molecules in normal plasma. Factor VIII antigen was isolated from plasma by solid-phase immunoprecipitation and an...

Translate the Penn State Worry Questionnaire (PSWQ) to Portuguese and evaluate the psychometric properties and the latent structure of the translated version in a large Brazilian college student sample to determine its psychometric reliability and validity. A first study employed...

Multiple factor analysis was used to interpret geographical variation of gene frequencies. Allelic frequencies at three loci (two esterase loci, Esr and Esh, and a malic dehydrogenase locus) from ants (Pogonomyrmex barbatus) collected throughout Texas and reported by Johnson et a...

Objective: To translate, adapt, and examine the factor structure and internal consistency of a Brazilian Portuguese version of the Smartphone Addiction Scale (SAS-BR) among university students. Methods: The SAS was translated and adapted for use with Brazilian samples. The resu...

The psychometric properties of the Portuguese version of the trait form of the State-Trait Anxiety Inventory (STAI-T) and its relation to the Beck Depression Inventory (BDI) were evaluated in a large Brazilian college student sample containing 845 women and 235 men. STAI-T scores...

It is now well established in case-control studies with individual matching that the statistical analysis must take the fact of individual matching into account. The problems of so doing have been thoroughly dealt with for the situation of the factor of interest being a two-level...

Degenerate oligonucleotide probes corresponding to a highly conserved region common to epidermal growth factor, transforming growth factor alpha, and vaccinia growth factor were used to identify a novel growth factor gene in the Shope fibroma virus genome. Sequence analysis indic...

ABSTRACT In the present study it is hypothesized that the germplasm of popcorn of tropical regions shows resistance to FAW, and the multivariate analysis can characterize the main traits of this resistance. Thus, the aim of this study was to identify key traits used to select fal...

Stress construct has been seen as one of the most important factors that generate different types and levels of disease in modern society. For this reason, it is important to construct and validate instruments able to measure stress and all aspects that involve this concept. It w...

Hemophilia B Chapel Hill is a mild hereditary hemorrhagic disorder in which the factor IX antigen is present in normal amounts but factor IX biological activity is markedly reduced. Previous studies have demonstrated that purified factor IX Chapel Hill has 8% of the activity of n...

Clinical data from 624 asbestos exposed workers were analysed by factor analysis. Fifteen clinical variables were found to reflect several underlying factors: "obstruction," "interstitial disorder," "x ray change," "air tapping," and "age/exposure." Scoring individual subjects al...
