Abstract: The Psyllidae are sap-suckers insects, highly host and food specific, found mainly in sprouts, and are considered important guava pests. Large populations of these insects can be hazardous, since they cause plant weakness by the toxic action of the saliva injected during their feeding process. The objective of this work was to verify the population fluctuation of the psyllidae Trizoida limbata in guava trees in Londrina, Paraná, Brazil. The monitoring of an adult T.limbata population was carried out in areas of wild guava trees, using 10 yellow adhesive traps, 30 m far from each other. Collection took place monthly from March 2002 to May 2003. T.limbata populations were found during every month of the year, reaching their peak in October. Average and maximum temperatures showed a significant correlation with the psyllidae population fluctuation, affecting it positively. Heavy rain periods and low temperatures were not restricting, but they caused a reduction in population Os psilídeos s o insetos sugadores de seiva, muito específicos com rela o ao hospedeiro e alimenta o, ocorrendo principalmente em brota es, sendo considerados uma importante praga de goiabeira. Altas popula es podem tornar-se nocivas, pois provocam depauperamento das plantas pela a o tóxica da saliva injetada durante sua alimenta o. O objetivo deste trabalho foi conhecer a flutua o populacional do psilídeo Triozoida limbata em goiabeiras na regi o de Londrina, Paraná. Em áreas de ocorrência natural de plantas de goiaba foi realizado o monitoramento da popula o de adultos utilizando-se 10 armadilhas adesivas amarelas, colocadas uma por planta, distanciadas cerca de 30 metros entre si. As coletas foram realizadas mensalmente de mar o de 2002 a maio de 2003. Popula es de T. limbata ocorreram durante todos os meses do ano, com pico em outubro. Temperaturas médias e máximas apresentaram correla o significativa com a popula o do psilídeos, afetando-a positivamente.

Abstract: Insect pests of snap beans in northern Paraná state – Brazil were monitored during four growing seasons: March – May, May – June, August – September, September – November. Adults of leafhopper (Empoasca kraemeri), whiteffly (Bemisia tabaci) and corn rootworm (Diabrotica speciosa) were monitored weekly using a cone trap. Leafhoppers nymphs were counted in mid height trifoliate leaves. The productive parameters evaluated in harvesting were: number of pods / plant; number of marketable pods; number of damaged pods divided in bent pods, empty pods or bored pods. Insect infestation were lower in August – September growing period, which yielded higher percent of marketable pods. The highest population of leafhopper occurred in March – May period, when the percent of curved pods were also the highest. Maximum population of whitefly occurred in early season of March – May growing period. Leaf beetle (D. speciosa) population did not surpass de damage threshold in any growing period, but was higher in March – May season. Objetivou-se conhecer a flutua o populacional dos principais insetos que atacam a cultura do feij ovagem UEL-1 cultivado em diferentes épocas, e seu efeito sobre as características das vagens. Os plantios foram conduzidos na fazenda-escola da Universidade Estadual de Londrina, em quatro diferentes períodos: mar o-maio; maio-junho; agosto-setembro; setembro-novembro. Foram avaliados semanalmente os adultos da cigarrinha-verde (Empoasca kraemeri), mosca-branca (Bemisia tabaci) e vaquinha (Diabrotica speciosa) com auxílio de cone entomológico. Contagens de ninfas de E. kraemeri foram realizadas em trifólios do estrato médio da planta. Ao final de cada safra, avaliou-se o número de vagens/planta, de vagens com tamanho comercial, de vagens encurvadas, chochas e perfuradas. As menores popula es de insetos ocorreram no plantio de agosto-setembro, quando obteve-se maior porcentagem de vagens com qualidade comercial. Maior popula o de E. kraemeri ocorreu no plantio de mar o-maio, coincidindo com maiores porcentagens de vagens encurvadas. A maior infesta o de B. tabaci ocorreu no início do plantio de mar o-maio. As popula es de D. speciosa mantiveram-se em níveis baixos na maioria dos plantios, com maior incidência em mar o-maio.

Abstract: The development of novel drug delivery systems is an essential step toward controlled site-specific administration of therapeutics within the body. It is desirable for delivery vehicles to be introduced into the body through minimally invasive means and, these vehicles should be capable of releasing drug to their intended location at a controlled rate. Furthermore, it is desirable to develop drug delivery systems that are capable of in vivo to suffer degradation and to deliver the drug completely, avoiding the need to surgically remove the vehicle at the end of its useful lifetime. Hydrogels are of particular interest for drug delivery applications due to their ability to address these needs in addition to their good biocompatibility, tunable network structure to control the diffusion of drugs and, tunable affinity for drugs. However, hydrogels are also limited for drug delivery applications due to the often quick elution of drug from their highly swollen polymer matrices as well as the difficulty inherent in the injection of macroscopic hydrogels into the body. This paper presents an overview to the advances in hydrogels based drug delivery. Different types of hydrogels can be used for drug delivery to specific sites in the gastrointestinal tract ranging from the oral cavity to the colon. These novel systems exhibit a range of several peculiar properties which make them attractive as controlled drug release formulations. Moreover, such materials are biocompatible and can be formulated to give controlled, pulsed, and triggered drug release profiles in a variety of tissues.

Abstract: Septic arthritis is a rheumatological emergency due to its potential for rapid articular destruction and permanent functional loss. Its incidence ranges between 4 and 29 cases per 100,000 person-years, and depends on population variables and preexisting structural joint abnormalities. Clinical manifestations, severity, treatment and prognosis depend on the aetiologic agent, patient basal status and articulation involved. The sternoclavicular and condrosternal articulations are rarely affected. A 24 years old man presented with fever and right shoulder pain. Physical examination revealed swelling, redness, increased local heat, intense pain and functional impairment of the patient’s right shoulder. Laboratory inflammatory markers were elevated. Right sternoclavicular articulation ultrasound, right sternoclavicular articulation X-ray, and galium bone scan have shown sternoclavicular arthritis and medial clavicular osteomyelitis. Blood cultures identified Staphylococcus aureus methicillin sensitive. The patient completed a six week antibiotic regimen and physical rehabilitation program. Herein, the authors report a case of sternoclavicular septic arthritis complicated with osteomyelitis and review aetiology, diagnosis, treatment and prognosis of this rare medical condition.

O pensamento político de éric Weil
Cardoso Simes,Mauro;
Enfoques , 2010,
Abstract: my puropose is to analyze the peculiar thinking of weil, according to the categories of reasoning, as a choice to avoid violence. in his definition of man, weil recovers the notion of realization, with which man is redefined in terms of what he must be and not merely for what he is. thereto, man is interpreted as formed by a political and social dimension. through language, men is capable of projecting and skipping his present reality towards the other temporal dimensions, since it is only there where he can express what he has not yet become and what he is not anymore, his own history. man is violent because he is not essentially reason. on this basis, the aim of philosophical reflection is to turn him, reasonably, into a less violent person.
Epistemología, ética y política según Karl Popper
Cardoso Simes,Mauro;
Enfoques , 2009,
Abstract: this paper looks to examine popper’s view of the critical discussion which, ultimately, is responsible for the creation of daring speculations both in epistemology and in the political and social fields. the author introduces the fallibilist presupposition of our assertions regarding truth. this popperian concern, according to the testability of our hypotheses, moved him to suggest a method which includes the natural and social sciences. for popper, the fundamental principle of unity in science was that the testing of hypotheses in social sciences had to be applied using the same method than in natural science. it is out of these popperian assertions supporting a methodological unity, the principle of fallibility, a sensible discussion and the search for truth-considered by popper both epistemological and ethical principles-that we suggest an analysis of these principles, thus linking epistemology and ethics in popper’s thought.
Redescription of Tijubina pontei, an Early Cretaceous lizard (Reptilia; Squamata) from the Crato Formation of Brazil
Simes, Tiago R.;
Anais da Academia Brasileira de Ciências , 2012, DOI: 10.1590/S0001-37652012000100008
Abstract: the record of gondwanan mesozoic lizards is very poor. among the few species described for this region there is tijubina pontei, an early cretaceous lizard from the crato formation (late aptian) of northeast brazil. its description is very brief and lacks most of its diagnostic characters and clear delimitation from other lizard species. here, a full redescription of the holotype is provided. t. pontei is demonstrated to be a valid species and a new diagnosis is provided with reference to olindalacerta brasiliensis, a contemporary species of the crato formation. it lacks the posteroventral and posterodorsal processes of the dentary; the tibial/fibular length equals the femoral length and its posterior dentary teeth are robust, cylindrically based, unsculptured and bear no cuspids. the systematic position of t. pontei still needs further clarification, but preliminary analyses indicate that it lies in a rather basal position among the squamata, similarly to o. brasiliensis.
