Lúcia Helena Pinheiro Martins, Hiroshi Noda, Maria Teresa Gomes Lopes, Maria Silvesnizia Paiva Mendona, Ayrton Luiz Urizzi Martins
Agricultural Sciences (AS) , 2016, DOI: 10.4236/as.2016.712075
Abstract: The family farm of the Upper Solim?es region has maintained the great genetic variability of the pumpkin (Cucurbita maxima Duchesne) by the in situ conservation of the landraces which are widely used as human food. The aim of this study was to estimate the current level of genetic variability of pumpkin landraces by means of estimation techniques of genetic parameters. Landraces areas samples were the family farming production units located in floodplains ecosystems of Benjamin Constant (Upper Solim?es River) and Iranduba (Lower Solim?es River), Amazonas. The split-plot designs were adopted at the treatments where the main plots were the five pumpkin landraces and one commercial cultivar. Each landrace was obtained six half sib families distributed in the sub-plots. Among the results of this study, it can be concluded that the genetic variation within the each landrace is greater than the genetic variation among the landraces. The qualitative morphological characteristics bring together half-sib families collected in geographically distant locations. It can be concluded that, through the estimation of genetic parameters, there is genetic variability among local cultivars collected in family farming of Benjamin Constant and Iranduba, Amazonas.

Revista Eletr?nica de Enfermagem , 2010,
Abstract: A pastilha de paraformaldeído é um agente esterilizante de artigos odonto-médico-hospitalares termossensíveis que tem sido questionado pelo seu alto poder carcinogênico e dificuldade de manuten o nos parametros definidos para sua utiliza o. Os objetivos deste estudo foram identificar e caracterizar a utiliza o do paraformaldeído na prática odontológica. O estudo foi realizado no município de Goiania no período de julho de 2005 a abril de 2006. Utilizou-se para a coleta de dados, um questionário previamente validado, aplicado aos responsáveis operacionais pelo reprocessamento de artigos em consultórios odontológicos. Participaram do estudo 204 profissionais e destes, 17 (8,3%) faziam uso de pastilhas de paraformaldeído. Embora estes profissionais tivessem ao seu alcance pelo menosum método físico de esteriliza o, as pastilhas de paraformaldeído foram utilizadas para o reprocessamento de artigos críticos e semicríticos, dentre estes alguns termorresistentes e descartáveis. Alguns profissionais indicaram a utiliza o de pastilhas de paraformaldeído com a finalidade de conserva o e/ou esteriliza o, mas o seu uso tornou-se proibido pelo Ministério da Saúde do Brasil em 2008.

Abstract: the hepatitis b virus (hbv) has been considered the major occupational risk agent for dentists. the central west region of brazil is considered an intermediate endemic pattern area, but currently there is no information about the hbv prevalence in dentists of goiania, goiás. this study aimed at the detection of the hbv infection rate and risk factors for dentists of goiania and the comparison of the obtained data with the general population and other groups. a randomized sample of 680 professionals participated in this study. all dentists gave written consent for the procedure and filled out a questionnaire about risk factors. the hbv serological markers were analyzed using elisa test and the presence of anti-hbc was observed in 41 (6.0%) of the dentists. none of them was hbsag positive. significant relationships with hbv positivity were observed with gender, the time working as a dentist and the use of incomplete personal protective equipment (ppe). the hbv prevalence found in this group of dentists was lower than the endemic pattern of the general population, other health care workers of the region and the dentists from other regions in brazil. these results may indicate a positive impact of vaccination considering the high adherence of the dentists to the immunization program (98.4%). finally, the use of complete ppe by the majority as well as other standard precautions recommended for health care workers could be responsible for the low hbv seroprevalence.

Abstract: the prevalence of antibodies against yersinia pestis in domestic carnivores (dogs and cats), in plague areas in the state of ceará, was analyzed to establish the importance of monitoring these animals within the routine practice of the plague control program. over the decade 1997-2006, 146,732 serum samples were examined (95,883 from dogs and 50,849 from cats), of which 2,629 (2,234 from dogs and 395 from cats) proved to be positive. the prevalence among dogs (85%) was higher than among cats (15%) throughout the decade and in all places, except in ibiapina in 1998. the significance of these findings has not yet been determined. studies on this zoonosis in brazil have been based on paradigms that did not cover all the elements involved in the zoonosis, thus making it impossible to properly understand the role of these carnivores. monitoring of plague foci conducted exclusively by means of dog surveys may result in progressive lack of knowledge of the epidemiological situation of plague, if supplementary inter-institutional research is not developed.

Complementary and Alternative Medicine in the Treatment of Chronic Pelvic Pain in Women: What Is the Evidence?
Sara Paiva,Márcia Mendona Carneiro
ISRN Pain , 2013, DOI: 10.1155/2013/469575
Abstract: Chronic pelvic pain (CPP) is defined as pain of at least 6 months’ duration that occurs in the lower abdomen or below the umbilicus and has resulted in functional or psychological disability or required intervention and treatment. Therapeutic interventions center around the treatment of CPP as a diagnosis in and of itself, and treatment of specific disorders that may be related to CPP. A multidisciplinary approach for diagnosis and treatment seems to be most effective for symptomatic relief. This paper reviews the evidence for such interventions as psychological treatments including the use of complementary and alternative medicine techniques for CPP in women. Unfortunately, finding the best evidence in this setting is difficult as only very few randomized controlled trials are available. A combination of treatments is usually required over time for the treatment of refractory CPP. The multifactorial nature of CPP needs to be discussed with the patient and a good rapport as well as a partnership needs to be developed to plan a management program with regular followup. Promotion of a multidisciplinary approach which includes complementary and alternative medicine techniques in managing CPP in women seems to yield the best results. 1. Introduction 1.1. Definition and Epidemiology An estimated one in three people suffer from chronic pain, a condition frequently associated with decreased health-related quality of life (HRQoL) and high levels of psychological distress [1]. Despite conventional healthcare utilization, nearly half of patients with chronic pain report their pain as not under control [2]. Limitations of drug therapy for chronic pain reflect the complex pathophysiology of the condition as well as the profound contribution of psychosocial factors to the perpetuation of pain and suffering [3, 4]. Chronic pelvic pain (CPP) is defined as pain of at least 6 months’ duration that occurs in the lower abdomen or below the umbilicus and has resulted in functional or psychological disability or required intervention and treatment. The pain may be recurring or constant [5]. Estimating the prevalence of CPP in women is challenging in part due to lack of consensus in the definition of CPP among investigators, and to the fact that only one third of women with CPP seek medical care [6–8]. Studies have quoted the range to be anywhere from 4% to 40% [6–9]. Even with a likely underestimation of prevalence, CPP accounts for 10% of indications for hysterectomy [10]. This yields 881.5 billion dollars in health care costs in the United States per year [9]. Although

Abstract: Background Paracoccin (PCN) is an N-acetylglucosamine-binding lectin from the human pathogenic fungus Paracoccidioides brasiliensis. Recombinant PCN (rPCN) induces a T helper (Th) 1 immune response when prophylactically administered to BALB/c mice, protecting them against subsequent challenge with P. brasiliensis. In this study, we investigated the therapeutic effect of rPCN in experimental paracoccidioidomycosis (PCM) and the mechanism accounting for its beneficial action. Methodology/Principal Findings Four distinct regimens of rPCN administration were assayed to identify which was the most protective, relative to vehicle administration. In all rPCN-treated mice, pulmonary granulomas were less numerous and more compact. Moreover, fewer colony-forming units were recovered from the lungs of rPCN-treated mice. Although all therapeutic regimens of rPCN were protective, maximal efficacy was obtained with two subcutaneous injections of 0.5 μg rPCN at 3 and 10 days after infection. The rPCN treatment was also associated with higher pulmonary levels of IL-12, IFN-γ, TNF-α, nitric oxide (NO), and IL-10, without IL-4 augmentation. Encouraged by the pulmonary cytokine profile of treated mice and by the fact that in vitro rPCN-stimulated macrophages released high levels of IL-12, we investigated the interaction of rPCN with Toll-like receptors (TLRs). Using a reporter assay in transfected HEK293T cells, we verified that rPCN activated TLR2 and TLR4. The activation occurred independently of TLR2 heterodimerization with TLR1 or TLR6 and did not require the presence of the CD14 or CD36 co-receptors. The interaction between rPCN and TLR2 depended on carbohydrate recognition because it was affected by mutation of the receptor's N-glycosylation sites. The fourth TLR2 N-glycan was especially critical for the rPCN-TLR2 interaction. Conclusions/Significance Based on our results, we propose that PCN acts as a TLR agonist. PCN binds to N-glycans on TLRs, triggers regulated Th1 immunity, and exerts a therapeutic effect against P. brasiliensis infection.
