Ambiência , 2006,
Abstract: O Aspergillus flavus e a subespécie próxima relacionada parasiticus têm sido reconhecidas por muito tempo como contaminadores principais de produtos organicos e inorganicos. A. flavus, um fungo comum do solo, pode infestar uma larga escala de produtos agrícolas. Algumas variedades de A. flavus produzem as aflatoxinas, que s o toxinas neoplásicas capazes de induzir neoplasia hepática em animais de laboratório. O crescimento de A. flavus e a biossíntese da aflatoxina depende da carca a, da umidade, da temperatura, do pH, da aera o e da microflora competindo. As aflatoxinas s o consideradas contaminantes naturais; cuja aproxima o ideal de controle é a preven o do crescimento do fungo e produ o das aflatoxinas nos produtos. As aflatoxinas (B1, B2, G1 e G2) s o metabólitos secundários associados à toxicidade causada por alimenta es em animais. As aflatoxinas s o relatadas como sendo hepatotóxicas, mutagênicas, imunossupressora e neoplásicas. A exposi o as aflatoxinas dietéticas é considerada um fator de risco importante para o desenvolvimento de neoplasia hepatocelular em determinadas regi es do mundo. A indu o de adutos no DNA pela aflatoxina B1 no fígado foi revista extensivamente em uma avalia o quantitativa de fatores de risco a neoplasias por aflatoxinas. As aflatoxinas s o pró-neoplásicas, reagindo com o ácido desoxirribonucléico (DNA), ácido ribonucléico (RNA) e as proteínas. Atualmente, vários avan os científicos têm sido feitos a fim de compreender a toxicologia clínica das aflatoxinas.

Abstract: the aim of this study was to evaluate the detection of new cases of leprosy in prudentópolis, state of paraná, from 1998 to 2005. additionally, we investigated the age group and predominant clinical form of leprosy cases. data were obtained from clinical-epidemiological records of confirmed leprosy cases that were notified in the information system for notifiable diseases, between 1998 and 2005. over this period, 222 leprosy cases were notified, of which 63% presented the multibacillary form, with predominance of the virchow clinical form, thus indicating a process of intense disease transmission. among these leprosy cases, 35% of the patients were at an economically active age (31 to 45 years old). these indicators showed that there was a high level of bacillus circulation in the community, considering that one risk factor for infection by the bacillus mycobacterium leprae is contact with untreated individuals who have the multibacillary form. this is despite the drastic reduction in leprosy prevalence over the last two decades, through the implementation of polychemotherapy and other preventive measures.

Abstract: the most common infections in human beings are caused by intestinal parasites. they can lead to a number of harmful effects, which could include, among others, intestinal obstruction, malnutrition, iron deficiency anemia, diarrhea, and poor absorption. in brazil, enteroparasites are one of the main public health issues. the present study aims at analyzing the distribution and frequency of enteroparasite occurrence in 635 children from seven community schools in the city of guarapuava, paraná (pr). in addition, we used similarity and diversity indices to analyze the parasite community. we found 475 samples with at least one parasite showing that 75.27% of children had enteroparasites. a smaller fraction (26.73%) of children harbored several parasites (multiparasitism), especially giardia duodenalis (56%), and ascaris lumbricoides (18%). statistical analysis showed that three (out of seven) children communities had higher similarity in frequency and amount of parasites. our results suggest that the children studied were highly infected by enteroparasites. these levels of infestation could be related to several factors, such as climate, social and economic conditions and characteristics of the parasites.

Leone Francisco Amorim Curado, José de Souza Nogueira, Luciana Sanches, Marcelo Sacardis Biudes, Thiago Rangel Rodrigues
Atmospheric and Climate Sciences (ACS) , 2012, DOI: 10.4236/acs.2012.24046
Abstract: The energy balance partitions in wetlands have gained notoriety due to the dynamics and importance of these areas for regional and local climate. Thus, the study was conducted about seasonal and interannual behavior energy fluxes, as well as the influences of the conditions of atmospheric stability and instability. The results showed highest fluxes happened in instability atmospheric conditions. The fluxes of latent and sensible heat showed seasonal variation, indicating that the water availability in the atmosphere has influence on the site energy partition, but the interannual patterns remained similar during the two years of study.

Colloquium Exactarum , 2010, DOI: 10.5747/ce.2010.v02.n2.e018
Abstract: Nowadays, the practice of accessing computers remotely using an Internet connection has become increasingly more frequent, or for transferring files or technical support performed by companies. Due to the need to remotely access files or perform technical support quickly and effectively, emerged the idea to develop an application that needed to be present only on the server computer, ie the machine would make available its resources. The client computer, the one responsible for access, it is any computer regardless of operating system, which possessed an Internet connection and a web browser with JavaScript resources. The Web browser on the client side is responsible for the communication interface and use of server resources. The application uses the HTTP communication protocol, JSP and Servlets technologies for presentation and delivery of services respectively, and JavaScript to allow user interaction with the server using the Web browser. The way it was designed the application, allows greater flexibility to the user, allowing it to access resources or perform technical support at any location where the requirements for running the application.

Atmospheric and Climate Sciences (ACS) , 2014, DOI: 10.4236/acs.2014.42025
Abstract:

Dynamics of flows of matter and energy these biomes are relevant to understanding of environmental processes that govern the biosphere-atmosphere interactions and between ecosystems. This study analyzed inter season and season of energy fluxes in Brazilian Savana through Bowen Ration Method. Results show differences in patterns LE in all season, LE predominant in wet while H in dry. This inversion in patterns of predominant components of the energy balance in wet and dry season because in wet season increase water content in soil and atmosphere due precipitation in this season providing more lost energy for atmosphere in shape LE through soil evaporation and plant transpiration, this results in LE and H in all season of the Brazilian Savana show higher variation in dynamics energy fluxes between surface and atmosphere, as well as energy partition in this biome. Statistics analyses presents than many climate variables influences LE and H in each season indicating complexity in this fluxes. More study is necessary to higher understand patterns energies fluxes in Brazilian Savana.

Abstract: OBJECTIVE: To evaluate and compare the biomechanical behavior of two different suture configurations: "X" and "Loop" in the preparation of tendons for knee ligament reconstruction. METHODS: We used common digital extensor tendons of bovine that can replace the human flexor tendons in experimental studies of traction. In the first group, point "X" suture with Ethibond (r) No. 5 began in the distal graft points transfixing, with spacing of 7.5 mm points to reach 03 cm distal to the beginning of the suture, returning suture in the same manner, transfixing the tendon in open spaces across the suture configuration "X". The second group, the point "Loop" was prepared with the same type Ethibond (r) No. 5 of the needle wire was removed for use only of the wire was mounted in a twofold manner in a single piece forming a needle loop. Started the suture 3 cm from the end of the graft through loops and transfixing points throughout the tendon substance, with spacing between dots of 7.5 mm. RESULT: The Maximum Force of Rupture suture in "Loop" was 444.45 N and the suture in "X" was 407.59 N with statistical significance (p = 0.030). The average Tension obtained at the suture in "Loop" was 27.67 MPa and at the suture in "X" was 25.73 MPa with a statistically significant difference (p = 0.036). The stiffness showed no statistical differences (p = 0.350) at 11.804 N / mm at the point where "Loop" and 11.570 N / mm at the suture "X". CONCLUSION: The suture in "Loop" had a higher biomechanical behavior to the suture "X", considering the Maximum Force and Tension. OBJETIVO: Avaliar e comparar o comportamento biomecanico de duas diferentes configura es de sutura, em "X" e em "La ada", no preparo dos tend es para reconstru o ligamentar no joelho. MéTODOS: Usaram-se tend es extensores digitais comuns bovinos que podem substituir os tend es flexores humanos em estudos experimentais de tra o. No primeiro grupo, ponto em "X", a sutura com fio Ethibond(r) no 5 iniciou-se na por o distal do enxerto, com pontos transfixantes e com espa amento entre os pontos de 7,5 mm até alcan ar 3 cm distal ao início da sutura, retornando a sutura da mesma maneira, transfixando o tend o nos espa os livres e cruzando a sutura em configura o de "X". O segundo grupo, ponto em "La ada", foi preparado com o mesmo tipo de fio Ethibond(r) no 5, a agulha do fio foi retirada para uso somente do fio, que foi montado de maneira dupla em uma agulha avulsa formando um la o. Iniciou-se a sutura a 3 cm da extremidade do enxerto por meio de la adas e pontos transfixantes em toda a substancia do tend o, co
Can Digital Games Be a Way of Improving the Neuroplasticity in Stroke Damage? Can the Adult Brain Grow New Cells or Rewire Itself in Response to a New Experience?  [PDF]

Abstract: Exploratory studies developed at several neurosciences laboratories at universities around the world show us through the experience that there is a biological process called neuroplasticity. Because of this oldest concept about the neuronal formation, scientists also thought that if a particular area of the adult brain was damaged, the nerve cells could not form new connections and the functions controlled by this field of the brain would be permanently lost or could not be regenerate. However, studies have overturned this old view, and currently, scientists recognize that the brain continues to reorganize itself by forming new neural connections during the life. This phenomenon is called neuroplasticity that refers to the potential which the brain should be reorganized by creating new neural pathways to adapt, as it needs.
