1. Reticular pattern detection in dermoscopy: an approach using Curvelet Transform
Abstract Introduction Dermoscopy is a non-invasive in vivo imaging technique, used in dermatology in feature identification, among pigmented melanocytic neoplasms, from suspicious skin lesions. Often, in the skin exam is possible to ascertain markers, whose identification and proper characterization is difficult, even when it is used a magnifying lens and a

2. Three-dimensional characterization of pores in Ti-6Al-4V alloy
The direct three-dimensional characterization of opaque materials through serial sectioning makes possible to visualize and better quantify a material microstructure, using classical metallographic techniques coupled with computer-aided reconstruction. Titanium alloys are used as biomaterials for bone implants because of its excellent mechanical properties,

6. The Escherichia coli NadR Regulator Is Endowed with Nicotinamide Mononucleotide Adenylyltransferase Activity
The first identification and characterization of a catalytic activity associated with NadR protein is reported. A computer-aided search for sequence similarity revealed the presence in NadR of a 29-residue region highly conserved among known nicotinamide mononucleotide adenylyltransferases. The Escherichia coli nadR gene was cloned into a T7-based vector and

7. Isolation and computer-aided characterization of MmeI, a type II restriction endonuclease from Methylophilus methylotrophus.
A Type II restriction endonuclease, MmeI, has been purified from the obligate methylotroph, Methylophilus methylotrophus. The enzyme was shown to have the non-palindromic recognition sequence 5'-T C C Pu A C (N)20-3', 3'-A G G Py T G (N)18-5' and to cleave (as indicated) on the 3' side, generating a two nucleotide 3' projection. Determination of the recognit

8. Computer-Aided Resolution of an Experimental Paradox in Bacterial Chemotaxis
Escherichia coli responds to its environment by means of a network of intracellular reactions which process signals from membrane-bound receptors and relay them to the flagellar motors. Although characterization of the reactions in the chemotaxis signaling pathway is sufficiently complete to construct computer simulations that predict the phenotypes of mutan

9. A new automated method for the segmentation and characterization of breast masses on ultrasound images
Segmentation is one of the first steps in most computer-aided diagnosis systems for characterization of masses as malignant or benign. In this study, the authors designed an automated method for segmentation of breast masses on ultrasound (US) images. The method automatically estimated an initial contour based on a manually identified point approximately at

10. Characterization of two related Epstein-Barr virus-encoded membrane proteins that are differentially expressed in Burkitt lymphoma and in vitro-transformed cell lines.
Two related but differentially expressed potential membrane proteins of Epstein-Barr virus are encoded by the same reading frame in the EcoRI D het region of the viral genome. Potential antigenic sites in the amino acid sequence of these proteins were selected by computer-aided prediction of the secondary structure and two oligopeptides corresponding to regi

11. Molecular structure of mammalian neuropeptide Y: analysis by molecular cloning and computer-aided comparison with crystal structure of avian homologue.
Identification and characterization of the cDNA encoding rat neuropeptide Y revealed the nucleotide sequence coding for a 98-amino acid precursor. The deduced amino acid sequence for rat neuropeptide Y is identical to the human peptide and is highly homologous to avian pancreatic polypeptide. The tertiary structure of avian pancreatic polypeptide has been pr

12. In Situ Characterization of Nitrospira-Like Nitrite-Oxidizing Bacteria Active in Wastewater Treatment Plants
Uncultivated Nitrospira-like bacteria in different biofilm and activated-sludge samples were investigated by cultivation-independent molecular approaches. Initially, the phylogenetic affiliation of Nitrospira-like bacteria in a nitrifying biofilm was determined by 16S rRNA gene sequence analysis. Subsequently, a phylogenetic consensus tree of the Nitrospira
