1. Electromagnetic Characterization of Aircraft Composite Materials and its Effects on the Antenna Performance
Abstract This paper presents an electromagnetic characterization of aircraft composite materials, as well as numerical and experimental analyses of its effects on the antenna performance. Two uncalibrated S-parameters characterization methods have been applied for retrieving the complex electrical permittivity in the L- and C-band, namely: Air-region method

2. Investigação dos mecanismos de ação do Amblyomin-X sobre a angiogênese in vivo induzida pelo VEGF / Investigation of mechanisms of action of Amblyomin-X on in vivo on VEGF-induced angiogenesis
Amblyomin-X é um inibidor de serinoprotease do tipo kunitz obtido de uma biblioteca de cDNA das glândulas salivares do carrapato Amblyomma cajannense. Dados preliminares mostraram que a injeção in vivo de Amblyomin-X reduziu a formação de massa tumoral induzida por células de melanoma B16F10 em camundongos. Com base neste dado e na ação de inibidore

3. Intensificação da terapia fotodinamica do cancer pela variação da pressão parcial do oxigenio no tecido : efeitos fisicos e biologicos
Photodynamic therapy is based on simultaneous involvement of three factors, namely: tumor tissue retention of an specific photosensitizer; local illumination of the lesion and occurrence of oxygen in the triplet state. Theoretically, changes in any one of these factors may be compensated by a change in the other factors, leading to the same therapeutic resul

4. Axonal transport of herpes simplex virions to epidermal cells: evidence for a specialized mode of virus transport and assembly.
To examine the transmission of herpes simplex virus (HSV) from axon to epidermal cell, an in vitro model was constructed consisting of human fetal dorsal root ganglia cultured in the central chamber of a dual-chamber tissue culture system separated from autologous skin explants in an exterior chamber by concentric steel cylinders adhering to the substratum t

5. Neutralizing Antibodies Inhibit Axonal Spread of Herpes Simplex Virus Type 1 to Epidermal Cells In Vitro
The ability of antibodies to interfere with anterograde transmission of herpes simplex virus (HSV) from neuronal axons to the epidermis was investigated in an in vitro model consisting of human fetal dorsal root ganglia innervating autologous skin explants in a dual-chamber tissue culture system. The number and size of viral cytopathic plaques in epidermal c

6. Anterograde Transport of Herpes Simplex Virus Proteins in Axons of Peripheral Human Fetal Neurons: an Immunoelectron Microscopy Study
Herpes simplex virus (HSV) reactivates from latency in the neurons of dorsal root ganglia (DRG) and is subsequently transported anterogradely along the axon to be shed at the skin or mucosa. Although we have previously shown that only unenveloped nucleocapsids are present in axons during anterograde transport, the mode of transport of tegument proteins and g

7. Control in time and space: Tramtrack69 cooperates with Notch and Ecdysone to repress ectopic fate and shape changes during Drosophila egg chamber maturation
Organ morphogenesis requires cooperation between cells, which determine their course of action based upon location within a tissue. Just as important, cells must synchronize their activities, which requires awareness of developmental time. To understand how cells coordinate behaviors in time and space, we analyzed Drosophila egg chamber development. We found

8. Reduced fear expression after lesions of the ventral hippocampus
The hippocampus has a critical role in several fundamental memory operations, including the conditioning of fear to contextual information. We show that the hippocampus is necessary also for unconditioned fear, and that the involved circuitry is at the ventral pole of the hippocampus. Rats with selective hippocampal lesions failed to avoid open arms in an el

9. The first tunicate from the Early Cambrian of South China
Here we report the discovery of eight specimens of an Early Cambrian fossil tunicate Shankouclava near Kunming (South China). The tunicate identity of this organism is supported by the presence of a large and perforated branchial basket, a sac-like peri-pharyngeal atrium, an oral siphon with apparent oral tentacles at the basal end of the siphonal chambe

10. Alpha and Gamma Interferons Inhibit Herpes Simplex Virus Type 1 Infection and Spread in Epidermal Cells after Axonal Transmission
The ability of alpha interferon (IFN-α) and IFN-γ to inhibit transmission of herpes simplex virus type 1 (HSV-1) from neuronal axon to epidermal cells (ECs), and subsequent spread in these cells was investigated in an in vitro dual-chamber model consisting of human fetal dorsal root ganglia (DRG) innervating autologous skin explants and compared with direc

11. Blockade of TGF-β inhibits mammary tumor cell viability, migration, and metastases
TGF-βs are potent inhibitors of epithelial cell proliferation. However, in established carcinomas, autocrine/paracrine TGF-β interactions can enhance tumor cell viability and progression. Thus, we studied the effect of a soluble Fc:TGF-β type II receptor fusion protein (Fc:TβRII) on transgenic and transplantable models of breast cancer metastases. System

12. Improved Model of Fluorescence Recovery Expands the Application of Multiphoton Fluorescence Recovery after Photobleaching in Vivo
Multiphoton fluorescence recovery after photobleaching is a well-established microscopy technique used to measure the diffusion of macromolecules in biological systems. We have developed an improved model of the fluorescence recovery that includes the effects of convective flows within a system. We demonstrate the validity of this two-component diffusion-con
