1. 7.0T ultrahigh-field MRI directly visualized the pedunculopontine nucleus in Parkinson’s disease patients
OBJECTIVES: The pedunculopontine nucleus (PPN) is considered a promising new target for neurostimulation in Parkinson’s disease (PD) patients with postural instability and gait disturbance that is refractory to other treatment modalities. However, the PPN is typically difficult to visualize with magnetic resonance imaging (MRI) at clinical field strengths

2. Development of a computer assisted gantry system for gaining rapid and accurate calyceal access during percutaneous nephrolithotomy
PURPOSE: To design a simple, cost-effective system for gaining rapid and accurate calyceal access during percutaneous nephrolithotomy (PCNL). MATERIALS AND METHODS: The design consists of a low-cost, light-weight, portable mechanical gantry with a needle guiding device. Using C-arm fluoroscopy, two images of the contrast-filled renal collecting system are ob

3. Impacto da utilização de tecnicas de lifting explorando diferença entre ferramentas interpretada e compilada na velocidade computacional da codificação wavelet de imagens estaticas / Impact of using lifting techniques to explore the differences between interpreted and compiled tools in the computational speed of wavelet static image coding
The field of analysis and compression of images has been received special attention of the scientific community because of including in the main systems of digital TV, satellite communications and mobile communications. In this context, the Discrete Transform Wavelet (TWD) arise how a powerful tool and its many advantages allowed your insertion in important

4. SEGMENTING TECHNIQUES OF IMAGES IN THE GENERATION OF PROGRAMS FOR MACHINERY OF COMMAND NUMERICAL / TÉCNICAS DE SEGMENTAÇÃO DE IMAGENS NA GERAÇÃO DE PROGRAMAS PARA MÁQUINAS DE COMANDO NUMÉRICO
This work describes a tool for extraction of features in 2D images applied to industrial automation. The method uses techniques implemented targeting of images into pieces model as detection of edges in the extraction of spatial coordinates of the image and import applications in CAD (Computer-Aided Design) for the generation of programmers for Computer Nume

5. Processamento de vídeo estereoscópico em tempo real para extração de mapa de disparidades / Real-time disparity map extraction in a dual head stereo vision system
Real-time analysis of stereo images for extraction of dimensional features has been focus of great interest, providing means for autonomous robot navigation and identification of objects in dynamic environments. This work describes a method based in pixel-to-pixel and windows based matching analysis, in stereo images, for constructing dense disparity maps. T

6. Generic Features of Tertiary Chromatin Structure as Detected in Natural Chromosomes
Knowledge of tertiary chromatin structure in mammalian interphase chromosomes is largely derived from artificial tandem arrays. In these model systems, light microscope images reveal fibers or beaded fibers after high-density targeting of transactivators to insertional domains spanning several megabases. These images of fibers have lent support to chromonema

7. Drug targeting of a peptide radiopharmaceutical through the primate blood-brain barrier in vivo with a monoclonal antibody to the human insulin receptor.
Peptide radiopharmaceuticals are potential imaging agents for brain disorders, should these agents be enabled to undergo transport through the blood-brain barrier (BBB) in vivo. Radiolabeled Abeta1-40 images brain amyloid in tissue sections of Alzheimer's disease autopsy brain, but this peptide radiopharmaceutical cannot be used to image brain amyloid in viv

8. Membrane association induces a conformational change in the Ebola virus matrix protein
The matrix protein VP40 from Ebola virus is targeted to the plasma membrane, where it is thought to induce assembly and budding of virions through its association with the lipid bilayer. Ebola virus VP40 is expressed as a monomeric molecule in solution, consisting of two loosely associated domains. Here we show that a C-terminal truncation of seven residues

9. Neighborhood-based tobacco advertising targeting adolescents.
Adolescent tobacco use remains a serious problem, and adolescents may be particularly receptive to the glamorous images tobacco companies use in advertisements. A relatively new form of neighborhood-based outdoor advertising, the illuminated bus-stop-shelter billboard, was studied to determine tobacco companies' use of this medium. We hypothesized that in 2

10. FtsZ Dynamics during the Division Cycle of Live Escherichia coli Cells
The dynamics and assembly of bacterial cell division protein FtsZ were monitored in individual, growing and dividing Escherichia coli cells in real time by microculture of a merodiploid strain expressing green fluorescent protein (GFP)-tagged FtsZ. Cells expressing FtsZ-GFP at levels less than or equivalent to that of wild-type FtsZ were able to grow and div

11. Microtubule-dependent Organization of Vaccinia Virus Core–derivd Early mRNAs into Distinct Cytoplasmic Structures
Vaccinia virus (vv) early transcription can be reconstituted in vitro from purified virions; in this assay mRNAs are made inside the viral core and subsequently extruded. Although the in vitro process has been extensively characterized, relatively little is known about vv early transcription in vivo. In the present study the fate of vv early mRNAs in infecte
