1. RET proto-oncogene mutations screening and detection in patients with multiple endocrine neoplasia type 2 using conformation sensitive gel electrophoresis / Detecção e rastreamento de mutações no proto-oncogene RET em pacientes com neoplasia endócrina múltipla tipo 2 por meio de eletroforese em gel sensível à conformação
A neoplasia endócrina múltipla tipo 2 (NEM-2) é uma síndrome tumoral herdada por mutações germinativas no proto-oncogene RET (RET) e transmitida por herança autossômica dominante. Atualmente, a indicação de tireoidectomia total preventiva é recomendada a indivíduos portadores de mutações no RET. Analisamos a aplicação do método Eletroforese

2. DNA sequence support for a close phylogenetic relationship between some storks and New World vultures.
Nucleotide sequences from the mitochondrial cytochrome b gene were used to address a controversial suggestion that New World vultures are related more closely to storks than to Old World vultures. Phylogenetic analyses of 1-kb sequences from 18 relevant avian species indicate that the similarities in morphology and behavior between New World and Old World vu

3. Detection of mutations in transgenic fish carrying a bacteriophage λcII transgene target
To address the dual needs for improved methods to assess potential health risks associated with chemical exposure in aquatic environments and for new models for in vivo mutagenesis studies, we developed transgenic fish that carry multiple copies of a bacteriophage λ vector that harbors the cII gene as a mutational target. We adapted a forward mutation

4. Genetic Analysis of nif Regulatory Genes by Utilizing the Yeast Two-Hybrid System Detected Formation of a NifL-NifA Complex That Is Implicated in Regulated Expression of nif Genes
In diazotrophic organisms, nitrogenase synthesis and activity are tightly regulated. Two genes, nifL and nifA, are implicated as playing a major role in this regulation. NifA is a transcriptional activator, and its activity is inhibited by NifL in response to availability of excess fixed nitrogen and high O2 tension. It was postulated that NifL binds to NifA
