1. Validação do consumo de ácidos graxos dietéticos com uso de biomarcadores e aplicação do método das tríades
Objetivo: Validar o consumo de ácidos graxos dietéticos obtido por meio de um questionário de freqüência alimentar (Q) em relação a múltiplos recordatórios de 24 horas (R) e um biomarcador sangüíneo, em uma população acima de 17 anos do Distrito Federal. Método: O estudo foi realizado com 81 indivíduos selecionados aleatoriamente em duas regi�

3. Solid-phase assembly of cow colostrum trypsin inhibitor gene.
A gene for cow colostrum trypsin inhibitor (CTI) was constructed from synthetic oligonucleotides using a novel method of solid-phase gene assembly. In the first step an anchor oligonucleotide was covalently bound to the CNBr-activated Sephacryl S-500 support. Next, triads or tetrads of separately annealed oligonucleotides were stepwise hybridized to the immo

4. Using Cases and Parents to Study Multiplicative Gene-by-Environment Interaction
With case-parent triads, one can estimate genotype relative risks by measuring the apparent overtransmission of susceptibility genotypes from parents to affected offspring. Results obtained using such designs, properly analyzed, resist both bias due to population structure and bias due to self-selection. Most diseases are not purely genetic, and environmenta

5. Estimation and inference for case–control studies with multiple non–gold standard exposure assessments: with an occupational health application
In occupational case–control studies, work-related exposure assessments are often fallible measures of the true underlying exposure. In lieu of a gold standard, often more than 2 imperfect measurements (e.g. triads) are used to assess exposure. While methods exist to assess the diagnostic accuracy in the absence of a gold standard, these methods are infreq

6. The giant cardiac membrane patch method: stimulation of outward Na(+)-Ca2+ exchange current by MgATP.
1. A giant patch method was used to study the stimulatory effect of cytoplasmic MgATP on outward Na(+)-Ca2+ exchange current in inside-out cardiac membrane patches (1-10 G omega seals with 14-24 microns pipette tip diameters) excised from guinea-pig, rabbit and mouse myocytes. 2. To establish the validity of the method with respect to structure, bleb formati
