Population differentiation in the banana leaf spot pathogen Mycosphaerella musicola, examined at a global scale

Single-copy restriction fragment length polymorphism (RFLP) markers were used to determine the genetic structure of the global population of Mycosphaerella musicola, the cause of Sigatoka (yellow Sigatoka) disease of banana. The isolates of M. musicola examined were grouped into four geographic populations representing Africa, Latin America and the Caribbean, Australia and Indonesia. Moderate levels of genetic diversity were observed for most of the populations (H = 0.22-0.44). The greatest genetic diversity was found in the Indonesian population (H = 0.44). Genotypic diversity was close to 50% in all populations. Population differentiation tests showed that the geographic populations of Africa, Latin America and the Caribbean, Australia and Indonesia were genetically different populations. Using F-ST tests, very high levels of genetic differentiation were detected between all the population pairs (F-ST > 0.40), with the exception of the Africa and Latin America-Caribbean population pair. These two populations differed by only 3% (F-ST = 0.03), and were significantly different (P < 0.05) from all other population pairs. The high level of genetic diversity detected in Indonesia in comparison to the other populations provides some support for the theory that M. musicola originated in South-east Asia and that M. musicola populations in other regions were founded by isolates from the South-east Asian region. The results also suggest the migration of M. musicola between Africa and the Latin America-Caribbean region.

Powered microdebridement treatment for recurrent respiratory papillomatosis

Laryngeal papillomatosis is a benign disease of lhe larynx caused by human papilloma virus. The disease has u variable clinical course and treatment focuses on debridement until clinical remission. The most common technique for removing the papilloma is by carbon dioxide laser ublution. Powered microdebridement. which is more familiar to endoscopic sinus surgeons, has been adapted for use in the larynx. We would like to report on this technique for removal of respiratory papillomas that we believe to be safer for both patients and staff. The cases of seven paediatric patients with recurrent respiratory papillomatosis treated with microdebridement of their papillomas have been retrospectively reviewed.

Hearing sensitivity and bone mineral density in older adults: the Health, Aging and Body Composition Study

Bone mineral density (BMD) may be associated with hearing loss in older adults. Demineralization of the cochlear capsule has been associated with hearing loss in those with Paget's disease of the bone and otosclerosis. Osteoporosis may also result in cochlear capsule demineralization. We hypothesized that lower hip BMD and lower heel ultrasound measurements would be associated with hearing loss in a population-based sample of 2,089 older black and white men and women. Bone parameters and hearing function were measured at the fourth clinical follow-up visit. Audiometric threshold testing was used to measure air- and bone-conduction hearing sensitivity. BMD of the hip and its subregions was measured using dual-energy X-ray absorptiometry. Calcaneal bone measurements [broadband ultrasound attenuation (BUA), speed of sound (SOS) and the quantitative ultrasound index (QUI)] were obtained using heel ultrasound. After adjusting for known hearing loss risk factors, no association was found between hearing and any of the bone measurements in whites and black women. In black men, however, lower hip BMD was associated with higher odds of hearing loss; for each standard deviation decrease in total hip BMD, the odds of hearing loss were 1.41 (95% confidence interval 1.08, 1.83), 1.39 (95% CI 1.07, 1.82) for femoral neck BMD and 1.65 (95% CI 1.26, 2.16) for trochanter BMD. Conductive hearing loss was associated with lower heel ultrasound measurements, though only among white men. The results of this study are mixed and inconclusive. Lower BMD of the hip and its subregions was associated with hearing loss among black men, but not among whites or black women. Lower measurements on heel ultrasound were associated with conductive hearing loss, though only among white men. These results suggest that axial and appendicular bone parameters may be modestly associated with hearing loss in older men, but not in women.

Diversity in the sunflower: Puccinia helianthi pathosystem in Australia

Sunflower rust caused by Puccinia helianthi is the most important disease of sunflower in Australia with the potential to cause significant yield losses in susceptible hybrids. Rapid and frequent virulence changes in the rust fungus population limit the effective lifespan of commercial cultivars and impose constant pressure on breeding programs to identify and deploy new sources of resistance. This paper contains a synopsis of virulence data accumulated over 25 years, and more recent studies of genotypic diversity and sexual recombination. We have used this synopsis, generated from both published and unpublished data, to propose the origin, evolution and distribution of new pathotypes of P. helianthi. Virulence surveys revealed that diverse pathotypes of P. helianthi evolve in wild sunflower populations, most likely because sexual recombination and subsequent selection of recombinant pathotypes occurs there. Wild sunflower populations provide a continuum of genetically heterogeneous hosts on which P. helianthi can potentially complete its sexual cycle under suitable environmental conditions. Population genetics analysis of a worldwide collection of P. helianthi indicated that Australian isolates of the pathogen are more diverse than non-Australian isolates. Additionally, the presence of the same pathotype in different genotypic backgrounds supported evidence from virulence data that sexual recombination has occurred in the Australian population of P. helianthi at some time. A primary aim of the work described was to apply our knowledge of pathotype evolution to improve resistance in sunflower to sunflower rust. Molecular markers were identified for a number of previously uncharacterised sunflower rust R-genes. These markers have been used to detect resistance genes in breeding lines and wild sunflower germplasm. A number of virulence loci that do not recombine were identified in P. helianthi. The resistance gene combinations corresponding to these virulence loci are currently being introgressed with breeding lines to generate hybrids with durable resistance to sunflower rust.

The renal cortical fibroblast in renal tubulointerstitial fibrosis

Renal cortical fibroblasts have key roles in mediating intercellular communication with neighboring/infiltrating cells and extracellular matrix (ECM) and maintenance of renal tissue architecture. They express a variety of cytokines, chemokines, growth factors and cell adhesion molecules, playing an active role in paracrine and autocrine interactions and regulating both fibrogenesis and the interstitial inflammatory response. They additionally have an endocrine function in the production of epoetin. Tubulointerstitial fibrosis, the common pathological consequence of renal injury, is characterized by the accumulation of extracellular matrix largely due to excessive production in parallel with reduced degradation, and activated fibroblasts characterized by a myofibroblastic phenotype. Fibroblasts in the kidney may derive from resident fibroblasts, from the circulating fibroblast population or from haemopoetic progenitor or stromal cells derived from the bone marrow. Cells exhibiting a myofibroblastic phenotype may derive from these sources and from tubular cells undergoing epithelial to mesenchymal transformation in response to renal injury. The number of interstitial myofibroblasts correlates closely with tubulointerstitial fibrosis and progressive renal failure. Hence inhibiting myofibroblast formation may be an effective strategy in attenuating the development of renal failure in kidney disease of diverse etiology. (c) 2005 Elsevier Ltd.

Interventions against obesity through increased lipolysis in adipose tissue

Obesity is a disease of excess adiposity affecting> 17% of men and >20% of women in Britain. Clinically, it is defined by a Body Mass Index (BMI, kg/m2) of 2:30. Obesity is a confounding factor that promotes insulin resistance, hyperinsulinaemia and type 2 diabetes. Type 2 diabetes accounts for >90% of all cases of diabetes, with a prevalence of 2-6% of adults in most western societies, a majority of which are overweight or obese. Weight loss in obese patients reduces the risk of developing diabetes by >50%. This thesis has investigated the first part of a two-stage therapeutic intervention against obesity in which adipose tissue lipolysis will be combined with increased energy expenditure: the approach is also designed to consider agents that will benefit glycaemic control in coexistent obesity and diabetes by improving insulin sensitivity. Rodent and human in vitro models of adipocyte biology and skeletal muscle have been developed, characterised and evaluated. They include isolated epididymal and parametrial adipocytes of lean and obese diabetic ob/ob mice, cultured 3T3-Ll preadipocytes, isolated human omental and subcutaneous adipocytes and rat L6 cultured muscle cells. Compounds investigated for anti-obesity and anti-diabetic properties include M2 (sibutramine metabolite), 3-guanidinopropionic acid and mazindol. In vivo studies were undertaken to investigate these compounds further in lean and ob/ob mice. In vivo studies indicated that M2 and 3-guanidinopropionic acid reduced body weight gain in ob/ob mice. The three compounds increased lipolysis in adipocytes isolated from lean and ob/ob mice and human adipose depots. The direct action of these compounds was mediated via a pathway involving the f3 adrenoceptors and components of the lipolytic signalling pathway, including protein kinase A and p38 MAP kinase. In addition, M2 and mazindol were capable of increasing glucose uptake into insulin sensitive tissues. M2 and mazindol can act directly on adipose tissue and skeletal muscle to increase glucose uptake via a pathway involving new protein synthesis and activation of the glucose transporters. The M2-stimulated pathway is activated by the conversion of phosphatidylinositol bisphosphate to phosphatidylinositol trisphosphate by phosphatidylinositol 3-kinase. Thus, M2, mazindol and 3-GPA showed pharmacodynamic properties which suggested they might be potential therapeutic treatments for obesity and diabetes.

Neurodegeneration is an early event in diabetic retinopathy:therapeutic implications

Diabetic retinopathy (DR) remains the leading cause of blindness among working-age individuals in developed countries. Current treatments for DR are indicated in advanced stages of the disease and are associated with significant adverse effects. Therefore, new pharmacological treatments for the early stages of DR are needed. DR has been classically considered to be a microcirculatory disease of the retina. However, there is growing evidence to suggest that retinal neurodegeneration is an early event in the pathogenesis of DR, which participates in the microcirculatory abnormalities that occur in DR. Therefore, the study of the underlying mechanisms that lead to neurodegeneration will be essential for identifying new therapeutic targets. From the clinical point of view, the identification of those patients in whom retinal neurodegeneration appears will be crucial for implementing early treatment based on neuroprotective drugs. When the early stages of DR are the therapeutic target, it would be inconceivable to recommend an aggressive treatment such as intravitreous injections. By contrast, topical administration of neuroprotective drugs by using eye drops is a possible option. However, clinical trials to determine the safety and effectiveness of this non-invasive route, as well as a standardisation of the methods for monitoring neurodegeneration, are needed.

Silencing Agrobacterium oncogenes in transgenic grapevine results in strain-specific crown gall resistance

Crown gall disease of grapevine induced by Agrobacterium vitis or Agrobacterium tumefaciens causes serious economic losses in viticulture. To establish crown gall-resistant lines, somatic proembryos of Vitis berlandieri × V. rupestris cv. 'Richter 110' rootstock were transformed with an oncogene-silencing transgene based on iaaM and ipt oncogene sequences from octopine-type, tumor-inducing (Ti) plasmid pTiA6. Twentyone transgenic lines were selected, and their transgenic nature was confirmed by polymerase chain reaction (PCR). These lines were inoculated with two A. tumefaciens and three A. vitis strains. Eight lines showed resistance to octopine-type A. tumefaciens A348. Resistance correlated with the expression of the silencing genes. However, oncogene silencing was mostly sequence specific because these lines did not abolish tumorigenesis by A. vitis strains or nopaline-type A. tumefaciens C58.

O atendimento do enfermeiro aos acidentados de trânsito terrestre

Considered the disease of the 20th century, the trauma is still the main cause of mortality in the age group of one to forty-four years old in World, and among several possible etiologies, the terrestrial transit accident has a strong impact on these statistics. The operational essentiality of nurses in the organization and integration of this scenario of care to the terrestrial transit casualties and the recognition that the moments after the trauma are decisive in the victim's prognosis, justify this study. Thus, it was sought to evaluate the nurses´care to casualties of land transit in this crucial process in a public hospital in urgent and emergency reference. This is an normative evaluative study with qualitative approach, carried out at the Hospital Monsenhor Walfredo Gurgel, located in the municipality of Natal/RN. Data collection occurred in May 2014, with approval of the Ethics Committee in Research (CAAE 27971114.9.0000.5537). The target population of the study were the nurses who work in Politrauma area of the hospital, following the inclusion criteria: agree to be part of the study voluntarily and act in the mentioned area and, as exclusion: allocated professionals in other areas (eventually acting in the area) and professionals on vacation and/or medical license. A semi-structured interview and non-participant observation was held to obtain data submitted subsequently to the technique of Content Analysis based on Bardin. The lack of specific training for trauma care was identified, whose severity can be mitigated with proper and skilled care. Therefore, the urgent need of the nurses' training for qualification of care to the victims of traffic accidents on land was evidenced

Gravidade do olho seco em pacientes internados em unidade de terapia intensiva: análise de conceito e construção de definições

Dry eye syndrome is a multifactorial disease of the tear film, resulting from the instability of the lacrimal functional unit that produces volume change, up or tear distribution. In patients in intensive care the cause is enhanced due to various risk factors, such as mechanical ventilation, sedation, lagophthalmos, low temperatures, among others. The study's purpose is to build an assessment tool of Dry Eye Severity in patients in intensive care units based on the systematization of nursing care and their classification systems. The aim of this study is to build an assessment tool of Dry Eye Severity in hospitalized patients in Care Unit Intensiva.Trata is a methodological study conducted in three stages, namely: context analysis, concept analysis, construction of operational definitions and magnitudes of nursing outcome. For the first step we used the methodological framework for Hinds, Chaves and Cypress (1992). For the second step we used the model of Walker and Avant and an integrative review Whitemore seconds, Knalf (2005). This step enabled the identification of the concept of attributes, background and consequent ground and the construction of the settings for the result of nursing severity of dry eye. For the construction of settings and operational magnitudes, it was used Psicometria proposed by Pasquali (1999). As a result of context analysis, visualized from the reflection that the matter should be discussed and that nursing needs to pay attention to the problem of eye injury, so minimizing strategies are created this event with a high prevalence. With the integrative review were located from the crosses 19 853 titles, selected 215, and from the abstracts 96 articles were read in full. From reading 10 were excluded culminating in the sample of 86 articles that were used to analyze the concept and construction of settings. Selected articles were found in greater numbers in the Scopus database (55.82%), performed in the United States (39.53%), and published mainly in the last five years (48.82). Regarding the concept of analysis were identified as antecedents: age, lagophthalmos, environmental factors, medication use, systemic diseases, mechanical ventilation and ophthalmic surgery. As attributes: TBUT <10s, Schimer I test <5 mm in Schimer II test <10mm, reduced osmolarity. As consequential: the ocular surface damage, ocular discomfort, visual instability. The settings were built and added indicators such as: decreased blink mechanism and eyestrain.

A atuação do enfermeiro no combate à dengue e a febre chikungunya: estudo comparativo nos municípios de Parnamirim e Santa Cruz/RN

The research aimed to analyze the role of nurses in the Family Health Strategy (FHS) in the control of Dengue and Chikungunya fever in the cities of Parnamirim and Santa Cruz. It is exploratory and descriptive nature of research, with a qualitative approach, which was developed with nurses of the Family Health Strategy in the municipalities of Parnamirim and Santa Cruz. All research process followed the ethical standards laid out research in Resolution No. 466/2012 of the National Health Council about research involving human beings. Data collection was performed using a semi-structured questionnaire with open and closed questions, organized into three parts: the profile of respondents, knowledge of the disease (transmission, prevention, control) and description of practices. The actions performed by nurses are punctual performed when there is growing disease of the number of cases in order to try to reduce the number of cases. The principal methodology used for them is to talk and guidelines resulting from campaigns and home visits, using leaflets and social networks. Regarding knowledge of nurses in the city of Santa Cruz on Dengue Fever and Chikungunya, is clearly some gaps. Nursing professionals know recognize a suspected case of dengue, but get confused when trying to explain to the Chikungunya fever, exhibiting the same symptoms of dengue. Although everybody had participated in a training on Chikungunya Fever and Dengue, a very limited knowledge of nurses regarding the clinical management. It is suggested that further studies are developed on the ground a few nurses have accepted to participate in the study, so that we can identify strategies, interventions, activities and nursing actions that are consistent with the reality of working in favor of coping Aedes epidemics aegypti that have positive impact on reducing the infestation rates and may be suitable and applied in other regions.

Pollen and macrofossil profiles from six cores in Illinois, U.S.A

Pollen analysis of Wisconsinan sediments from eleven localities in northern and central Illinois, combined with the results of older studies, allows a first general survey of the vegetational changes in Illinois during the last glaciation. In the late Altonian (after 40,000 B.P.), pine was already the most prevalent tree type in northern Illinois. Probably because of the influence of the last Altonian ice advance to northern Illinois, pine migrated to the south and reached south-central Illinois, which was at that time a region of prairie, with oak and hickory trees in favorable sites. Likewise in the late Altonian, spruce appeared in northern Illinois. Spruce also expanded its area to the south during the Wisconsinan, reaching south-central Illinois only after 21,000 B.P., in the early Woodfordian. Deciduous trees (predominantly oak) were present in south-central Illinois throughout the Wisconsinan. Their prevalence decreased to the north. The vegetation during the different subdivisions of the last glacial period in Illinois was approximately as follows: Late Altonian: Pine/spruce forest with some deciduous trees in northern and central Illinois; prairie and oak/hickory stands in south-central Illinois; immigration of pine. Farmdalian: Pine/spruce forest in central Illinois; deciduous trees and pine in south-central Illinois, with areas of open vegetation, perhaps similar to the present-day transition of prairie to forest in the northern Great Plains. Woodfordian: Northern and central Illinois ice covered; in south central Illinois, spruce and oak as dominant tree types, but also pine and grassland. During the Woodfordian, pine and spruce disappeared again from south-central Illinois, and oak/hickory forest and prairie again prevailed. The ice-free areas of northern Illinois become populated temporarily with spruce, but later there is proof of deciduous forest in this region. Pollen investigations in south-central Illinois have shown convincingly that deciduous trees could survive relatively close (less than 60 km) to the ice margin. Therefore the frequently presented view that arctic climatic conditions prevailed in North America during the last glaciation far south of the ice margin can be refuted for the Illinois area, confirming the opinion of other authors resulting from investigations of fossil mollusks and frost-soil features. The small number of localities investigated still permits no complete reconstruction of the vegetation zones and their possible movements in Illinois. During the Altonian and Farmdalian in Illinois, a vegetational zonation probably existed similar to that of today in North America. As the ice pushed southward as far as 39° 20' N. lat in the early Woodfordian, this zonation was apparently broken up under the influence of a relatively moderate climate. In any case, the Vandalia area, which was only about 60 km south of the ice, was at that time neither in a tundra zone nor in a zone of boreal coniferous forest.

Sarcoidosis, alveolar β-actin and pulmonary fibrosis

BACKGROUND: Sarcoidosis is a multisystem granulomatous disease of unknown aetiology. Proteins present within the alveolar space early in sarcoidosis disease may provide an insight into novel mechanisms for the development of fibrotic disease and in particular pulmonary fibrosis.

METHODS: A modified two-dimensional difference gel electrophoresis protocol was applied to the human bronchoalveolar lavage fluid (hBALF) of four patients with non-persistent pulmonary interstitial disease at 4-year follow-up (defined as mild disease) and four patients who developed pulmonary interstitial disease at 4-year follow-up (defined as severe disease). The protein β-actin was identified by LC-MS/MS from a preparative gel and found to be significantly elevated in early lavages from the severe disease group. To look at the potential pro-fibrotic effects of this protein, primary human pulmonary fibroblasts (CCD-19Lu) were treated with recombinant β-actin following which qPCR and ELISA assays were used to measure any effects.

RESULTS: We found that β-actin levels were significantly elevated in early hBALF samples in patients who subsequently developed severe disease when compared to the mild group. Treating primary human pulmonary fibroblasts with recombinant β-actin led to enhanced gene expression of the pro-fibrotic markers alpha smooth muscle actin and collagen 1 as well as the increased secretion of interleukin-13 and metalloproteinases 3 and 9.

CONCLUSION: Free β-actin within the lungs of sarcoidosis patients potentially may contribute to disease pathogenesis particularly in the context of abnormal remodelling and the development of pulmonary fibrosis.

Stress e Emergência Médica: níveis e factores de stress em profissionais de emergência pré–hospitalar

O stress é a doença da actualidade, devido à exigência e à pressão emocional que o meio pode exercer sobre todas as pessoas, quer no seu ambiente pessoal quer no ambiente profissional. O termo stress serve cada vez mais como justificação ou forma de expressão de irritações, mal-estar físico e mental, cansaço, ansiedade e depressões. Todavia torna-se pertinente percebermos a evolução do stress enquanto conceito e enquanto doença. Neste trabalho contextualizamos o stress no âmbito da Emergência Pré – Hospitalar, explorando-o, avaliando-o e analisando-o, de modo a podermos perceber os níveis de stress e de que forma os Profissionais de Emergência a ele estão sujeitos. Considerando a base teórica deste estudo definimos, como objectivo geral do trabalho, a avaliação de níveis e factores de stress percepcionados pelos profissionais de emergência médica e como objectivos específicos do estudo a descrever e caracterizar, a nível da região centro, os indivíduos que desempenham funções na emergência préhospitalar, verificar a percepção dos mesmos no que respeita ao stress na sua vida profissional, conhecer como percepcionam os níveis de stress em situações profissionais de emergência e identificar a sua percepção no que concerne aos níveis de stress diário no seu quotidiano. Com estes objectivos, utilizamos uma amostra de 184 profissionais de Emergência Médica divididos por quatro profissões [Médicos, Enfermeiros, Técnicos de Ambulância de Emergência (TAE) e Operadores de Central de Emergência Médica(OPCEM)], com idades compreendidas entre os 20 e os 56 anos. Realizámos ainda um estudo descritivo explorando os questionários de stress no INEM (Instituto Nacional de Emergência Médica) e o Questionário de Vulnerabilidade do Stress com variáveis do estudo demográfico. Podemos concluir que o stress está presente nas actividades de emergência. A sua presença relaciona-se, por um lado, com uma maior ou menor discriminação dos factores stressantes e, por outro, numa maior ou menor centração no sujeito, nomeadamente, um maior perfeccionismo e intolerância à frustração que se apresentam como distressantes para a actividade profissional de emergência. Os aspectos estudados permitem-nos clarificar o sentido e a utilidade do conceito, a sua operacionalidade e a sua importância nos profissionais de emergência. / Stress is the disease of our time, due to the requirement and emotional pressure that the media can have on all people, both in their personal environment and in the professional environment. The word stress increasingly serves as a justification or form of expression of irritation, physical discomfort and mental fatigue, anxiety and depression. However it is pertinent to realize the evolution of stress as a concept and as a disease. In this work, we contextualize under the stress of the Pre - Hospital Emergency, exploring it, assessing it and analyzing it, so you can see the stress levels and how the Emergency Professionals are subject to it. Whereas the theoretical basis of this study as a strategic objective of the work, the assessment of levels and stress factors perceived by medical emergency professionals and specific objectives of the study description and characterization, the level of the center, individuals who perform functions in pre-hospital emergency, check their perception with regard to the stress in your life, know how they experience the stress levels of professionals in emergency situations and identify the perceptions of individuals regarding the levels of daily stress in their daily lives. For this we used a sample of 184 professionals of Medical Emergency divided by four professions [(Doctors, Nurses, Technicians Ambulance Emergency (TAE), Operators of Emergency Medical Center (OPCEM)], aged 20 to 56 years. We conducted a descriptive study also exploring the questionnaires of stress in INEM(National Institute of Medical Emergency) and Vulnerability Questionnaire Stress with variables of the study population. We can conclude that stress is present in emergency activities. Its presence is related to, first, with more or less stressful factors of discrimination and, secondly, a greater or lesser concentration on the subject, in particular, greater perfectionism and intolerance to frustration that stand as unstressed for the activity of emergency professionals. The areas studied will clarify the meaning and usefulness of the concept, its operation and its importance in day-to-day occupation of emergency.
