1. Cutaneous polyarteritis nodosa causing refractory skin deformation and pigmentation as sequel
Abstract: A 39-year-old woman presented with prominent and painful livedo reticularis lesions spreading on her upper and lower extremities. Histopathologically, the small-to medium-sized arteries in the deep dermis and subcutis showed necrotizing vasculitis with cellular infiltration, suggesting cutaneous polyarteritis nodosa. The serum levels of inflammator

2. Dynamics of the interaction between body fluid and Ti cp: the influence of surface functionalization in the first stages of osseointegration
INTRODUCTION: Regenerative therapies using biomaterials require accurate information on interactions between the implanted material and the human body. To improve the process of bone regeneration it is necessary to obtain a better understanding of the influence of the surfaces on the early stages of osseointegration. This work aims to investigate the dynamic

3. Porous stainless steel for biomedical applications
Porous 316L austenitic stainless steel was synthesized by powder metallurgy with relative density of 0.50 and 0.30 using 15 and 30 wt. (%) respectively of ammonium carbonate and ammonium bicarbonate as foaming agents. The powders were mixed in a planetary ball mill at 60 rpm for 10 minutes. The samples were uniaxially pressed at 287 MPa and subsequently vacu

4. Um modelo multiescalas de autômatos celulares para pandemia da dengue / A multiscale cellular automata model for the pandemic of Dengue
The dramatic resurgence and emergence of epidemic dengue and dengue hemorragic fever in the last two decades neatly define a global pandemic. The dispersion of dengue viruses combines local infections of humans bited by infective mosquitoes inside a city with long-range transmissions to non-infective vectors that feed the blood of infected people arriving fr

5. Identificando regras de transição de autômato celular probabilista via algoritmo genético em sistemas epidemiológicos / Identificando regras de transição de autômato celular probabilista via algoritmo genético em sistemas epidemiológicos
Probabilistic cellular automata can be used to model the spreading of contagious diseases in a population composed by susceptible, infected and recovered individuals. At each time step, a susceptible individual can either remain susceptible or contract the disease from infected individuals, where the probability related to the contagion depends on the number

6. A micro-spreading improvement for spermatogenic chromosomes from Triatominae (Hemiptera-Reduviidae)
Cytogenetics of triatomines have been a valuable biological tool for the study of evolution, taxonomy, and epidemiology of these vectors of Trypanosoma cruzi. Here we present a single microtube protocol that combines micro-centrifugation and micro-spreading, allowing high quality cytogenetic preparations from male gonadal material of Rhodnius prolixus and Tr

7. Damage spreading in a model of gene regulation in scale-free networks / Damage spreading in a model of gene regulation in scale-free networks / Propagação de danos em um modelo de regulação gênica em redes livres de escalas / Propagação de danos em um modelo de regulação gênica em redes livres de escalas
A compreensão de todos os elementos funcionais que controlam a expressão gênica é um desafio da biologia molecular moderna. Vários avanços no entendimento do funcionamento das redes de genes foram feitos com a descrição desse sistema complexo por meio de modelos de redes. A caracterização dessas redes permite conhecer como tais sistemas são organi

8. AlteraÃÃes hematolÃgicas e funcionais causadas por venenos de subespÃcies brasileiras de Crotalus durissus e suas fraÃÃes isoladas / HematolÃgicas and functional alterations caused by venom of Brazilian subspecies of Crotalus durissus and its isolated fractions
Os acidentes ofÃdicos de serpentes representam um sÃrio problema de SaÃde PÃblica nos paÃses tropicais, tanto pela freqÃÃncia com que ocorrem e/ou pela morbi-mortalidade que ocasionam. As serpentes do gÃnero Crotalus estÃo representadas no Brasil pela espÃcie Crotalus durissus, a qual se divide em seis subespÃcies. Nosso trabalho teve como objetiv

9. The human immunodeficiency virus preventive vaccine research at the French National Agency for acquired immunodeficiency syndrome research
The human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) epidemic is of unprecedented gravity and is spreading rapidly, notably in the most disadvantaged regions of the world. The search for a preventive vaccine is thus an absolute priority. For over 10 years the French National Agency for AIDS research (ANRS) has been committed to an o

10. Selection algorithm of spreading sequences for CDMA systems with space-time coding and antenna array / Algoritmo de escolha de sequencias de espalhamento em sistemas CDMA com codificação espaço-temporal e arranjo de antenas
The performance of mobile communication systems based on the CDMA technique is limited by interference. In this thesis, we propose a selection algorithm of spreading sequences with fixed length for interference mitigation on CDMA systems over frequency-selective fading channels, that is based on the minimization of the overall mean bit error probability of t

11. Stochastic dynamics of coupled systems and damage spreading
We study the damage spreading in the one-dimensional Ising model by means of the stochastic dynamics resulting from coupling the system and its replica by a family of algorithms that interpolate between the heat bath and the Hinrichsen-Domany algorithms. At high temperatures the dynamics is exactly mapped to the Domany-Kinzel probabilistic cellular automaton

12. Evaluation of phagocytes from healthy buffaloes (Bubalus bubalis) milk bred in Sao Paulo state / Avaliação dos fagócitos no leite de búfalas (Bubalus bubalis) hígidas criadas no Estado de São Paulo
The aim of this study was to make a quantitative and a qualitative evaluation of phagocytes from healthy buffaloes (Bubalus bubalis) milk bred in Sao Paulo state. For this purpose, the experiment was divided in three parts, called chapters, as specific objectives: (1) establish and study the cellularity of healthy buffaloes milk; (2) establish an adequate me
