    Full Text Available Excessive ineffective erythropoiesis in thalassemia intermedia may cause extramedullary hematopoiesis (EMH, resulting in spleen and liver enlargement or masses in several tissues, mainly paravertebrally. Other less frequent locations of diffuse compensatory EMH are kidneys, adrenal glands, breasts, spinal cord, pleura, pericardium, duramater, adipose tissue and skin, although intrathoracic extramedullary hematopoiesis is a rare condition. Management strategies have included radiation and transfusion therapy. Hydroxyurea with transfusion therapy has been associated with clinical regression of EMH in thalassemia. We report an uncommon case of intrathoracic EMH in a patient with beta-thalassemia intermedia, that showed significant recovery with HU therapy.A excessiva eritropoese ineficaz na talassemia pode causar hemato-poese extramedular (HEM, resultando em hepatomegalia, esplenomegalia e massas de tecido hematopoético em diversos tecidos. Localizações de HEM compensatória menos freqüentes são rins, glândulas adrenais, canal medular, pleura, pericárdio, duramáter, tecido adiposo e pele. Entretanto, HEM intratorácica é condição rara. Estratégias terapêuticas incluem radiação e transfusões sanguíneas. O uso de hidroxiuréia concomitante a terapêutica transfusional foi associado à regressão clínica da HEM na talassemia. Nós descrevemos um caso de HEM intratorácica em paciente portadora de talassemia intermédia, com significante regressão do quadro após terapêutica isolada com hidroxiuréia.

  16. [Current management of thalassemia intermedia].

    Thuret, I

    2014-11-01

    Thalassemia intermedia is a clinical entity where anemia is mild or moderate, requiring no or occasional transfusion. Non-transfusion-dependent thalassemia encompasses 3 main clinical forms: beta-thalassemia intermedia, hemoglobin E/beta-thalassemia and alpha-thalassemia intermedia (HbH disease). Clinical severity of thalassemia intermedia increases with age, with more severe anemia and more frequent complications such as extramedullary hematopoiesis and iron overload mainly related to increased intestinal absorption. Numerous adverse events including pulmonary hypertension and hypercoagulability have been associated with splenectomy, often performed in thalassemia intermedia patients. The potential preventive benefit of transfusion and chelation therapies on the occurrence of numerous complications supports the strategy of an earlier therapeutic intervention. Increasing knowledge about pathophysiological mechanisms involved in thalassemia erythropoiesis and related iron overload is currently translating in novel therapeutic approaches.

    Full Text Available Our understanding of the molecular and pathophysiological mechanisms underlying the disease process in patients with thalassaemia intermedia (TI has substantially increased over the past decade. TI encompasses a wide clinical spectrum of beta-thalassaemia phenotypes. Some TI patients are asymptomatic until adult life, whereas others are symptomatic from as young as 2 years of age. A number of clinical complications commonly associated with TI are rarely seen in thalassaemia major, including extramedullary hematopoiesis, leg ulcers, gallstones, thrombosis and pulmonary hypertension. There are a number of options currently available for managing patients with TI, including transfusion therapy, iron chelation therapy, modulation of foetal haemoglobin production and haematopoietic stem cell transplantation. However, at present, there are no clear guidelines for an orchestrated optimal treatment plan.

    Definición
    La terapia génica es el proceso por el cual se inserta material genético en una célula, con el fin de hacer que ésta produzca una proteína normal. Las utilidades van desde curar enfermedades unigénicas hasta modificar el equilibrio del sistema inmune, permitiendo la modulación de la respuesta contra cualquier antígeno. En esencia es cambiar la secuencia del genotipo de un organismo para que tenga implicaciones fenotípicas.

    Historia
    Desde el descubrimiento de las enzimas de restricción en el año de 1970 por Arber y Hamilton se sentaron las bases para transferir genes entre diferentes células u organismos, inclusive pertenecientes a diferentes especies. En 1978 se realizó la primera hormona recombinante insertando el gen de la insulina en una bacteria E. coli. De allí en adelante se afianzaron los conocimientos necesarios para transferir genes a células humanas con el fin de alterar el fenotipo patológico y generar una nueva forma terapéutica. La primera transferencia se realizó en el año de 1989 en un paciente con una inmunodeficiencia. Aunque no se encontraron efectos clínicos se explicitó que tampoco había efectos deletéreos como muchos apocalípticamente habían pronosticado. En 1990 se trató con terapia génica un paciente que padecía de la deficiencia de la enzima adenosin-deaminasa presentando infecciones bacterianas a repetición.

    Aunque la mejoría fue temporal, con este ensayo se comprobó que la terapia génica tenía posibilidades terapéuticas reales....

  10. Content-based intermedia synchronization

    Science.gov (United States)

    Oh, Dong-Young; Sampath-Kumar, Srihari; Rangan, P. Venkat

    1995-03-01

    Inter-media synchronization methods developed until now have been based on syntactic timestamping of video frames and audio samples. These methods are not fully appropriate for the synchronization of multimedia objects which may have to be accessed individually by their contents, e.g. content-base data retrieval. We propose a content-based multimedia synchronization scheme in which a media stream is viewed as hierarchial composition of smaller objects which are logically structured based on the contents, and the synchronization is achieved by deriving temporal relations among logical units of media object. content-based synchronization offers several advantages such as, elimination of the need for time stamping, freedom from limitations of jitter, synchronization of independently captured media objects in video editing, and compensation for inherent asynchronies in capture times of video and audio.

    1977-12-01

    Full Text Available A terapia da linguagem na afasia foi estudada em 15 pacientes, 8 do sexo masculino e 7 do sexo feminino; a idade variou de menos de 10 anos a mais de 50 anos; em 11 casos a afasia era sequela de acidente vascular cerebral e, em 4, de traumatismo crânio-encefálico. Quanto ao tipo de afasia, 5 pacientes apresentavam déficits predominantemente de expressão e 10 apresentavam déficits receptivos e expressivos em graus equiparáveis. Em 6 casos a terapia foi iniciada dentro dos 3 primeiros meses de instalação do quadro; nos restantes foi iniciada mais tardiamente. Dos 15 pacientes, 11 apresentaram evolução satisfatória, a qual não depndeu do grau de afasia, do tipo de afasia, da idade do paciente, do tipo de patologia e do intervalo entre a instalação do quadro afásico e o início da terapia. A terapia da linguagem no paciente afásico é efetiva, o prognóstico não pode ser feito a priori. Somente a evolução do caso com sua retestagem criteriosa poderá dar dados realmente úteis para se falar em evolução.

  15. Transfusion regimens in thalassemia intermedia

    Full Text Available Thalassemia intermedia (TI is a heterogeneous disease, in terms of both clinical manifestations and underlying molecular defects. Some TI patients are asymptomatic until adult life, whereas others are symptomatic from early childhood. In contrast with patients with Thalassemia major (TM, the severity of anemia is less and the patients do not require transfusions during at least the first few years of life. Many patients with TI, especially older ones, have been exposed to the multiple long-term effects of chronic anemia and tissue hypoxia and their compensatory reactions, including enhanced erythropoiesis and increased iron absorption. Bone marrow expansion and extramedullary hematopoiesis lead to bone deformities and liver and spleen enlargement. Therapeutic strategies in TI are not clear and different criteria are used to decide the initiation of transfusion and chelation therapy, modulation of fetal hemoglobin production, and hematopoietic stem cell transplantation on an individual basis. The clinical picture of well-treated TM patients with regular transfusionchelation therapy is better from TI patients who have not received adequate transfusion therapy. There is a significant role of early blood transfusion to prevent and treat complications commonly associated with TI, such as extramedullary erythropoiesis and bone deformities, autoimmune hemolytic anemia, leg ulcers, gallstones, pseudoxantoma elasticum, hyperuricosuria, gout and pulmonary hypertension, which are rarely seen in thalassemia major. Nowadays, indications of transfusion in patients with TI are chronic anemia (Hb < 7 g/dL, bone deformities, growth failure, extramedullary erythropoiesis, heart failure, pregnancy and preparation for surgical procedures. Conclusion: Adequate (regular or tailored transfusion therapy is an important treatment modality for increasing the quality of life in patients with thalassemia intermedia during childhood. 就临床表象和潜在的分子缺

    2012-01-01

    Our understanding of the molecular and pathophysiological mechanisms underlying the disease process in patients with β-thalassemia intermedia has substantially increased over the past decade. Earlier studies observed that patients with β-thalassemia intermedia experience a clinical-complications profile that is different from that in patients with β-thalassemia major. In this article, a variety of clinical morbidities are explored, and their associations with the underlying disease pathophysiology and risk factors are examined. These involve several organs and organ systems including the vasculature, heart, liver, endocrine glands, bone, and the extramedullary hematopoietic system. The effects of some therapeutic interventions on the development of clinical complications are also discussed. PMID:22762026

    Cardiac complications are among the most serious problems of thalassemia intermedia patients. The current study was initiated to address the latter issue through the study of the echocardiographic findings and correlate it with clinical characteristics of thalassemia intermedia patients in Duhok, Kurdistan region, Iraq. An echocardiographic assessment of 61 beta-thalassemia intermedia cases was performed. It included 30 males and 31 females, with a mean age 19.6 ± 7.5 years. The standard echostudy of two-dimension and M-mode measurements of cardiac chambers were done. The continuous doppler regurgitant jet of tricuspid and pulmonary valves were recorded. Left ventricle diastolic function was assessed by pulsed doppler of mitral valve inflow. To correlate the clinical with echocardiographic findings, patients were divided, according to tricuspid regurgitant velocity, into three groups (intermedia patients. Therapeutic trails targeting these complications are indicated, and echocardiographic assessment is necessary to be offered early for thalassemia intermedia.

    2017-01-01

    We report a case of ruptured massa intermedia (MI) as a sequela of hydrocephalus. A single case report is presented describing the sequelae of tumor bed hematoma after a posterior fossa hemangioblastoma resection in which the patient bled 3 days after surgery, resulting in secondary hydrocephalus and subsequently dilatation of the third ventricle, which resulted in rupture of the MI. The patient was managed on emergency basis with an external ventricular drain then endoscopically with a third ventriculostomy and clot extraction. Absent MI is not uncommon in hydrocephalic patients, and it is assumed to be the result of rupture from acute dilatation of the third ventricle. Our case report proves this assumption and documents the presence and absence of the MI before and after developing hydrocephalus. Copyright © 2016 Elsevier Inc. All rights reserved.

    β-Thalassemia intermedia is a clinical condition of intermediate gravity between β-thalassemia minor, the asymptomatic carrier, and β-thalassemia major, the transfusion-dependent severe anemia. It is characterized by a significant clinical polymorphism, which is attributable to its genetic heterogeneity. Ineffective erythropoiesis, chronic anemia, and iron overload contribute to the clinical complications of thalassemia intermedia through stepwise pathophysiological mechanisms. These complications, including splenomegaly, extramedullary erythropoiesis, iron accumulation, leg ulcers, thrombophilia, and bone abnormalities can be managed via fetal hemoglobin induction, occasional transfusions, chelation, and in some cases, stem cell transplantation. Given its clinical diversity, thalassemia intermedia patients require tailored approaches to therapy. Here we present an overview and novel approaches to the genetic basis, pathophysiological mechanisms, clinical complications, and optimal management of thalassemia intermedia.

    Full Text Available This study aimed to estimate the prevalence of depression in nursing staff working in Intensive Care Units of hospitals from a city in Northwestern São Paulo State - Brazil, examining its association with participants' socio-demographic characteristics. The Beck Depression Inventory was applied to a sample of 67 nursing workers from three general hospitals, showing an 28.4% prevalence of depression. The analysis based on the multiple model showed a significant association between depression and marital status (OR=1.52, night work (OR=1.46 and double shifts (OR=2.11. Also, there were significant percentages of workers who reported discouragement, sadness and hopelessness. In conclusion, the prevalence of depression is significant and more attention should be paid to this problem workers at these units face. Further studies are needed in the attempt to broaden knowledge on the subject, which can support strategies to guarantee attention to ICU nursing workers' physical and mental health needs.Este estudio fue realizado con el objetivo de estimar la prevalencia de depresión, en trabajadores de enfermería de Unidades de Terapia Intensiva (UTI de hospitales de una ciudad del Noroeste del estado de Sao Paulo, analizando su asociación con las características sociodemográficas de los participantes.

    Prevotella intermedia, a major periodontopathogen, has been shown to be resistant to many antibiotics. In the present study, we examined the effect of the FDA-approved iron chelators deferoxamine (DFO) and deferasirox (DFRA) against planktonic and biofilm cells of P. intermedia in order to evaluate the possibility of using these iron chelators as alternative control agents against P. intermedia. DFRA showed strong antimicrobial activity (MIC and MBC values of 0.16 mg ml(-1)) against planktonic P. intermedia. At subMICs, DFRA partially inhibited the bacterial growth and considerably prolonged the bacterial doubling time. DFO was unable to completely inhibit the bacterial growth in the concentration range tested and was not bactericidal. Crystal violet binding assay for the assessment of biofilm formation by P. intermedia showed that DFRA significantly decreased the biofilm-forming activity as well as the biofilm formation, while DFO was less effective. DFRA was chosen for further study. In the ATP-bioluminescent assay, which reflects viable cell counts, subMICs of DFRA significantly decreased the bioactivity of biofilms in a concentration-dependent manner. Under the scanning electron microscope, P. intermedia cells in DFRA-treated biofilm were significantly elongated compared to those in untreated biofilm. Further experiments are necessary to show that iron chelators may be used as a therapeutic agent for periodontal disease.

  13. Prevotella intermedia induces prostaglandin E2 via multiple signaling pathways.

    Prostaglandin E(2) (PGE(2)) plays important roles in the bone resorption of inflammatory diseases such as rheumatoid arthritis and periodontitis via specific prostaglandin receptors (i.e., EP1-EP4). In this study, the authors examined whether Prevotella intermedia regulates PGE(2) production and EP expression in human periodontal ligament fibroblasts (hPDLs); they also explored the potential signaling pathways involved in PGE(2) production. P. intermedia induced PGE(2) production and cyclooxygenase-2 (COX-2) expression in a dose- and time-dependent manner. Indomethacin and NS-398 completely abrogated the P. intermedia-induced PGE(2) production without modulating COX-2 expression. Specific inhibitors of extracellular signal-regulated kinase, c-Jun N-terminal kinase, p38, phosphatidylinositol 3-kinase, and protein kinase C--but not c-AMP and protein kinase A--significantly attenuated the P. intermedia-induced COX-2 and PGE(2) expression. P. intermedia reduced EP1 expression in a concentration- and time-dependent manner. The results indicate that the COX-2-dependent induction of PGE(2) by P. intermedia in hPDLs is mediated by multiple signaling pathways.

    Invasion of oral epithelial cells by pathogenic oral bacteria may represent an important virulence factor in the progression of periodontal disease. Here we report that a clinical isolate of Prevotella intermedia, strain 17, was found to invade a human oral epithelial cell line (KB), whereas P. intermedia 27, another clinical isolate, and P. intermedia 25611, the type strain, were not found to invade the cell line. Invasion was quantified by the recovery of viable bacteria following a standard antibiotic protection assay and observed by electron microscopy. Cytochalasin D, cycloheximide, monodansylcadaverine, and low temperature (4°C) inhibited the internalization of P. intermedia 17. Antibodies raised against P. intermedia type C fimbriae and against whole cells inhibited invasion, but the anti-type-C-fimbria antibody inhibited invasion to a greater extent than the anti-whole-cell antibody. This work provides evidence that at least one strain of P. intermedia can invade an oral epithelial cell line and that the type C fimbriae and a cytoskeletal rearrangement are required for this invasion.

    Full Text Available El reto de mejorar el tratamiento actual de los gliomas de alto grado ha sido abordado con inmensa creatividad, desarrollándose una gran variedad de estrategias para este fin. El análisis interino de un estudio fase III mostró que el beneficio de la terapia standard mejora al complementarla con terapia de campos eléctricos alternantes (Novo TTF-100 A; dadas las limitaciones de un análisis interino, queda por establecer la real magnitud y relevancia clínica de esta mejoría. El presunto beneficio de usar tratamiento antiviral contra citomegalovirus es muy controvertido y su utilidad no se ha demostrado en forma fehaciente. Las terapias antiangiogénicas han mostrado ser útiles para el manejo de las recurrencias, al menos como tratamiento sintomático, pero no han demostrado mejorar la sobrevida en pacientes de novo. La terapia dirigida contra señales intracelulares de crecimiento, conceptualmente muy atractiva, todavía no ha logrado resultados clínicos exitosos. Hay datos preliminares promisorios respecto al uso clínico de vacunas antitumorales y de inmunomodulación con inhibidores de “checkpoints”; también hay algunos datos preliminares a favor del uso de virus oncolíticos. La terapia genética parece estar en etapas aún muy tempranas de su desarrollo y probablemente demore más tiempo en llegar a demostrar utilidad clínica.

    Blanca Lilia Reyes-Rocha

    Full Text Available Actualmente, ha cobrado relevancia el uso de la terapia húmeda en la cura de las heridas crónicas; sin embargo, persiste el uso de la terapia tradicional como técnica para lograr la cicatrización de las mismas. El caso que presentamos tiene como propósito determinar el costo-beneficio del empleo de apósitos de cura en ambiente húmedo versus cura tradicional en un paciente con úlcera en la extremidad inferior. Los resultados muestran que el coste es mayor con la terapia en ambiente húmedo; sin embargo, el periodo de cicatrización de la herida es menor en comparación con el tiempo de cicatrización que conlleva la cura tradicional; esto redunda en un beneficio para el paciente al alcanzar su recuperación en un menor tiempo. Estos hallazgos permiten proponer hipótesis para estudios posteriores bajo otro diseño metodológico, a fin de generar evidencia científica que coadyuve en la mejora de los procesos de atención en beneficio de la población con este tipo de padecimiento.

As diferentes modalidades de alimentação do recém-nascido prematuro - especialmente para aqueles de muito baixo peso - e seu efeito protetor na diminuição de complicações (mormente as infecciosas foram analisadas. A utilização preferencial do leite materno na nutrição enteral, o controle das ofertas energético-protéicas, o início precoce da nutrição enteral mínima, a introdução precoce da alimentação parenteral - nas primeiras 24 horas - e a utilização dos imunonutrientes que tenham estudos suficientes para fundamentar sua indicação podem se constituir em boas diretrizes adjuvantes na prevenção da sepse neonatal e da enterocolite necrosante. Sem embargo, percebe-se a necessidade de mais estudos - preferencialmente multicêntricos, controlados e randomizados - para esclarecer o papel protetor da nutrição no RNPT, não somente na prevenção de infecções, mas também para auxiliar o desenvolvimento neural e a prevenção de consequências deletérias futuras.

  2. Morphometric and genetic analysis of Arcella intermedia and Arcella intermedia laevis (Amoebozoa, Arcellinida) illuminate phenotypic plasticity in microbial eukaryotes.

    Porfírio-Sousa, Alfredo L; Ribeiro, Giulia M; Lahr, Daniel J G

    2017-04-01

    Testate amoebae are eukaryotic microorganisms characterized by the presence of an external shell (test). The shell morphology is used as a diagnostic character, but discordance between morphological and molecular data has been demonstrated in groups of arcellinids (Amoebozoa), one of the principal groups of testate amoebae. Morphology of the test is supposed to differentiate genera and species and it is applied in ecological, monitoring and paleontological studies. However, if phenotype does not reflect genotype, conclusions in these types of studies become severely impaired. The objective of this work is to evaluate the morphometrical and morphological variation of the closely related and morphologically similar taxa Arcella intermedia laevis Tsyganov and Mazei, 2006 and Arcella intermedia (Deflandre 1928) Tsyganov and Mazei, 2006 in nature and in cultured individuals and see how these are correlated with molecular data. Our results demonstrate that phenotypic plasticity in Arcella intermedia make morphological distinctions impossible in both taxa. Arcella intermedia and Arcella intermedia laevis are molecularly identical for SSU rDNA and a mitochondrial molecular marker (NAD9/7). We conclude that morphological techniques alone cannot identify phenotypic plasticity from natural populations. More work is clearly needed to better understand the morphological, morphometric and molecular variability in these organisms. Copyright © 2016 Elsevier GmbH. All rights reserved.

    To investigate the effect of thalidomide in patients with thalassemia intermedia. We observed the effect of thalidomide in seven patients with thalassemia intermedia requiring blood transfusion. Four of the patients were transfusion-independent, and three patients were transfusion-dependent. For the four transfusion-independent patients, hemoglobin concentration increased significantly (≥2 g/dl) in three and moderately (1-2 g/dl) in one. After 3 months of treatment, hemoglobin concentration increased 3.2 ± 1.2 g/dl compared to pretreatment. Among the three transfusion-dependent patients, transfusion was terminated after one month of treatment in one patient and decreased >50% in the other two patients, accompanied by an increase in the average hemoglobin concentration. Thalidomide had a significant effect in patients with thalassemia intermedia. Further studies of a larger scale and more rigorous design are warranted.

    Full Text Available Se han propuesto muchos tratamientos psicológicos para el abordaje de los trastornos de personalidad, realizándose gran variedad de estudios para comprobar la eficacia de los mismos. Y aunque hasta la fecha no se ha podido demostrar empíricamente que exista ningún tratamiento establecido como eficaz, si se ha demostrado que los tratamientos cognitivo conductuales y conductuales resultan probablemente eficaces para el tratamiento de estos trastornos, en concreto y de forma más específica para el Trastorno Límite de Personalidad. El objetivo de este trabajo es ofrecer una revisión a nivel teórico y empírico de los tres modelos de tratamiento considerados actualmente de mayor eficacia: Terapia Dialéctica Conductual, Terapia de Aceptación y Compromiso y Psicoterapia Analítico Funcional, incluidas dentro de las llamadas Terapias de conducta de tercera generación.

    Full Text Available Si queremos evaluar el grado de desarrollo local que aporta el Tren de Alta Velocidad (TAV en una ciudad es primordial observar la capacidad de los actores del territorio de organizarse para aprovechar sus recursos endógenos. Mediante la elaboración de una nueva metodología, se propone el estudio del proceso de desarrollo de tres ciudades intermedias con TAV, Lérida (España, Aviñón (Francia y Novara (Italia. En las conclusiones se ponen de manifiesto ciertos problemas propios de la ciudad intermedia en la ejecución de su proyecto local, básicamente la existencia de una relación multiescalar conflictiva y de una débil red de actores locales. La fragilidad de este contexto urbano es debida a la falta de correctos procesos de gobernanza interna y externa.

Entre los pacientes que completaron el tratamiento (n= 152 la TCC/I+PN mostró tasas de abstinencia a los 6 meses y al año, mayores que la TCC/NI+PN, mientras que la TCC/I mostró tasas de abstinencia que no eran significativamente diferentes de las de los otros dos tratamientos. Estos resultados sugieren que los parches de nicotina se deberían utilizar siempre con una terapia cognitiva conductual lo más intensiva posible y que la utilización de esta última terapia en solitario debería gozar de mayor relevancia en las guías clínicas para dejar de fumar.

    Periodontitis is an inflammatory disease caused by periodontal bacteria in subgingival plaque. These bacteria are able to colonize the periodontal region by evading the host immune response. Neutrophils, the host's first line of defense against infection, use various strategies to kill invading pathogens, including neutrophil extracellular traps (NETs). These are extracellular net-like fibers comprising DNA and antimicrobial components such as histones, LL-37, defensins, myeloperoxidase, and neutrophil elastase from neutrophils that disarm and kill bacteria extracellularly. Bacterial nuclease degrades the NETs to escape NET killing. It has now been shown that extracellular nucleases enable bacteria to evade this host antimicrobial mechanism, leading to increased pathogenicity. Here, we compared the DNA degradation activity of major Gram-negative periodontopathogenic bacteria, Porphyromonas gingivalis, Prevotella intermedia, Fusobacterium nucleatum, and Aggregatibacter actinomycetemcomitans. We found that Pr. intermedia showed the highest DNA degradation activity. A genome search of Pr. intermedia revealed the presence of two genes, nucA and nucD, putatively encoding secreted nucleases, although their enzymatic and biological activities are unknown. We cloned nucA- and nucD-encoding nucleases from Pr. intermedia ATCC 25611 and characterized their gene products. Recombinant NucA and NucD digested DNA and RNA, which required both Mg 2+ and Ca 2+ for optimal activity. In addition, NucA and NucD were able to degrade the DNA matrix comprising NETs. © 2016 The Authors Molecular Oral Microbiology Published by John Wiley & Sons Ltd.

Con el fin de contribuir de manera flexible desde la Formación Laboral y Profesional a que los estudiantes definan su trayectoria formativa, en este trabajo se analizan las ventajas de las salidas intermedias en una carrera universitaria, sin afectar la continuidad de los estudios superiores ni la calidad en la formación del egresado universitario. Estas permiten a los estudiantes obtener un título de nivel medio que los pone en condiciones de salir al mercado laboral con un perfil ocupacional relacionado con la carrera universitaria que estudia. Desde la perspectiva curricular la propuesta realizada se basa en currículos flexibles con salidas intermedias donde pueden ser de gran utilidad los cursos optativos y/o electivos.PALABRAS CLAVE: currículo; salidas intermedias; asignaturas optativasTOWARDS A FLEXIBLE CURRICULUM: INTERMEDIATE EXITS AND OPTIONAL COURSES ABSTRACTTraditionally, the curricula of the university degree courses have been focused on the formation of professionals within the required period for their graduation (5-6 years, with a single exit to the labour market. This research is aimed at contributing, from the Labour and Professional Formation of the students, to the definition of their formative process, according to their needs and interests. This paper also analyses the advantages of the intermediate exits in a university degree course, and how they allow students to obtain a college degree without affecting the continuation of the higher education studies or the quality of the formation of the university graduate. Such reality favours the insertion of the students in the labour market under conditions that suit the qualifications and experience related to the degree they are doing.

    Full Text Available Beta-thalassemia is due to a defect in the synthesis of the beta-globin chains, leading to alpha/beta imbalance, ineffective erythropoiesis, and chronic anemia. The spectrum of thalassemias is wide, with one end comprising thalassemia minor, which consists of a mild hypochromic microcytic anemia with no obvious clinical manifestations, while on the other end is thalassemia major, characterized by patients who present in their first years of life with profound anemia and regular transfusion requirements for survival. Along the spectrum lies thalassemia intermedia, a term developed to describe patients with manifestations that are neither mild enough nor severe enough to be classified in the spectrum’s extremes. Over the past decade, our understanding of β-thalassemia intermedia has increased tremendously with regards to molecular information as well as pathophysiology. It is now clear that β-thalassemia intermedia has a clinical presentation as well as complications associated with the disease that are different from those of β-thalassemia major. This review is designed to tackle issues related to β-thalassemia intermedia from the basic definition of the disease to paramedical issues, namely the quality of life in these patients. Genetics and pathophysiology are revisited, as well as the complications specific to this disease. These complications include effects on several organ systems, including the cardiovascular, hepatic, endocrine, renal, brain, and skeletal systems. Extramedullary hematopoiesis is also discussed in this article. Risk factors are highlighted and cutoffs are identified to minimize morbidities in β-thalassemia intermedia. Several treatment modalities are considered by shining a light on the pros and cons of each modality, as well as the role of special pharmacological agents in the progress of the disease and its morbidities.

    Full Text Available En este artículo se presenta una revisión de la literatura sobre las células madre como terapia para la cirrosis hepática, con énfasis en describir la situación científica actual y las implicaciones clínicas de los avances. Se ha propuesto la terapia celular en cirrosis por la escasez de donantes de hígado y las complicaciones derivadas de la terapia inmunosupresora. Las células madre se pueden obtener de diferentes fuentes como el blastocisto, la médula ósea e incluso hepatocitos maduros; pero la capacidad de proliferación y diferenciación de cada uno de estos tipos celulares es distinta y, entre otras consideraciones, es lo que va a definir su utilidad clínica final. En la literatura se encuentran varios estudios en modelos animales y en seres humanos que evalúan la seguridad y factibilidad de esta técnica en cuanto a la mejoría de la fibrosis, la capacidad de diferenciación y replicación celulares y algunos parámetros clínicos. Los resultados, aunque alentadores, se deben interpretar con cuidado. En conclusión, antes de aceptar esta modalidad terapéutica se requieren estudios de mejor calidad y con homogeneidad metodológica porque su uso aún es controversial.

    Olano, C.; Lemarchand, G.; Sanz, A. J.; Bava, J. A.

    El objetivo principal de este proyecto consiste en el estudio de la distribución y abundancia del CH en nubes interestelares a través de la observación de las líneas hiperfinas del CH en 3,3 GHz. El CH es una molécula de amplia distribución en el espacio interestelar y una de las pocas especies que han sido observadas tanto con técnicas de radio como ópticas. Desde el punto de vista tecnológico se ha desarrollado un cabezal de receptor que permitirá la realización de observaciones polarimétricas en la frecuencia de 3,3 GHz, con una temperatura del sistema de 60 K y un ancho de banda de 140 MHz, y que será instalado en el foco primario de la antena parabólica del IAR. El cabezal del receptor es capaz de detectar señales polarizadas, separando las componentes de polarización circular derecha e izquierda. Para tal fin el cabezal consta de dos ramas receptoras que amplificarán la señal y la trasladarán a una frecuencia más baja (frecuencia intermedia), permitiendo de esa forma un mejor transporte de la señal a la sala de control para su posterior procesamiento. El receptor además de tener características polarimétricas, podrá ser usado en el continuo y en la línea, utilizando las ventajas observacionales y de procesamiento de señal que actualmente posee el IAR.

    Full Text Available Terapia gênica é um procedimento médico que envolve a modificação genética de células como forma de tratar doenças. Os genes influenciam praticamente todas as doenças humanas, seja pela codificação de proteínas anormais diretamente responsáveis pela doença, seja por determinar suscetibilidade a agentes ambientais que a induzem. A terapia gênica é ainda experimental, e está sendo estudada em protocolos clínicos para diferentes tipos de doenças. O desenvolvimento de métodos seguros e eficientes de transferência gênica para células humanas é um dos pontos mais importantes na terapia gênica. Apesar do grande esforço dirigido na última década para o aperfeiçoamento dos protocolos de terapia gênica humana, e dos avanços importantes na pesquisa básica, as aplicações terapêuticas da tecnologia de transferência gênica continuam ainda em grande parte teóricas. O potencial da terapia gênica é muito grande, devendo ainda causar grande impacto em todos os aspectos da medicina.Gene therapy is a medical intervention that involves modifying the genetic material of living cells to fight disease. Genes influence virtually every human disease, either by encoding for abnormal proteins, which are directly responsible for the disease, or by causing a susceptibility to environmental agents which induce it. Gene therapy is still experimental, and is being studied in clinical trials for many different types of diseases. The development of safe and effective methods of implanting normal genes into the human cell is one of the most important technical issues in gene therapy. Although much effort has been directed in the last decade toward improvement of protocols in human gene therapy, and in spite of many considerable achievements in basic research, the therapeutic applications of gene transfer technology still remain mostly theoretical. The potential for gene therapy is huge and likely to impact on all aspects of medicine.

    Discula betulina is a foliar pathogen on birch (Betula) and Gnomonia intermedia is found on overwintered birch leaves. Perithecia of G. intermedia developed in vitro on colonies of D. betulina isolated from birch tissues in late summer, and single ascospores of G. intermedia consistently developed into colonies similar to D. betulina, producing typical D. betulina conidia. Isolates of D. betulina could be grouped into two mating types, which produced fertile perithecia of G. intermedia when mated with each other. Mycelia from single-ascospore and single-conidial isolates were inoculated onto shoots of downy birch, causing lesions and die-back from which D. betulina was consistently isolated. ITS region ribosomal DNA sequence analysis confirmed the results of the morphological and mating studies, and found that the closest known relatives of G. intermedia/D. betulina are Gnomoniella nana and Sirococcus clavigignenti-juglandacearum. The conclusion from these studies is that D. betulina is the anamorph of G. intermedia.

    Research objective is to study the efficacy of recombinant erythropoietin (epoetin alfa) as alternative method of treatment beta-thalassemia intermedia. Study involved 58 patients with beta-thalassemia intermedia (23 women and 35 men). In all observed patients was defined levels of hemoglobin (Hb), red blood cells (RBC), erythrocyte indexes (MCV, MCH, MCHC), hemoglobin fractions (HbA, HbA2, HbF), serum ferritin, serum erythropoietin before and after administrated rEPO. All patients received rEPO during 6 month at the dose - 10000 IU subcutaneously. The majority of patients - 39 (67%) had a good response to rEPO (increase in hemoglobin level more than 20 g/l); 16 patients (28%) had a mean response (increase in Hb 10 - 20 g/l); in 3 (5%) patients occurred poor response to rEPO therapy (increase in Hb intermedia patients there was a statistically significant change in the number of RBC, levels of HbF and sEPO. The evaluation of interdependence between the indices of the baseline sEPO and increased Hb values in patients after rEPO treatment revealed the presence of the reverse direct relationship (r=-0.67). Based on the results, it can be concluded that the use of rEPO in complex therapy of beta-thalassemia intermedia leads to increased levels of Hb and consequently reducing the need for blood transfusions, and accordingly expected to prevent severe complications of blood transfusion (alloimmunization, hypersplenism, iron overload, contamination transmissible infections) facilitating normal growth and development, and a better quality of life.

    Full Text Available The production of pigments by edible filamentous fungi is gaining attention as a result of the increased interest in natural sources with added functionality in the food, feed, cosmetic, pharmaceutical and textile industries. The filamentous fungus Neurospora intermedia, used for production of the Indonesian food “oncom”, is one potential source of pigments. The objective of the study was to evaluate the fungus’ pigment production. The joint effect from different factors (carbon and nitrogen source, ZnCl2, MgCl2 and MnCl2 on pigment production by N. intermedia is reported for the first time. The scale-up to 4.5 L bubble column bioreactors was also performed to investigate the effect of pH and aeration. Pigment production of the fungus was successfully manipulated by varying several factors. The results showed that the formation of pigments was strongly influenced by light, carbon, pH, the co-factor Zn2+ and first- to fourth-order interactions between factors. The highest pigmentation (1.19 ± 0.08 mg carotenoids/g dry weight biomass was achieved in a bubble column reactor. This study provides important insights into pigmentation of this biotechnologically important fungus and lays a foundation for future utilizations of N. intermedia for pigment production.

    The massa intermedia is an inconstant parenchymal band connecting the medial thalami. It may be thickened in various disease processes such as Chiari II malformation or absent in other disease states. However, the massa intermedia may also be absent in up to 30% of normal human brains. To the best of my knowledge, detailed imaging findings of massa intermedia duplication have only been described in a single case report. An additional case of thalamic massa intermedia duplication discovered on a routine brain MR performed for dysmorphic facial features is reported herein.

    Prevotella intermedia/nigrescens is one of the well-known pathogens causing periodontal diseases, and the red florescence excited by the visible blue light caused by the protoporphyrin IX in the bacterial cells could be useful for the chair-side detection. The aim of this study was to evaluated levels of periodontal pathogen, especially P. intermedia in clinical samples of red fluorescent dental plaque. Thirty two supra gingival plaque samples from six individuals were measured its fluorescence at 640nm wavelength excited by 409nm. Periodontopathic bacteria were counted by the Invader PLUS PCR assay. Co-relations the fluorescence intensity and bacterial counts were analyzed by Person's correlation coefficient and simple and multiple regression analysis. Positive and negative predictive values of the fluorescence intensities for with or without P. intermedia in supragingival plaque was calculated. When relative fluorescence unit (RFU) were logarithmic transformed, statistically significant linear relations between RFU and bacterial counts were obtained for P. intermedia, Porphyromonas gingivalis and Tannerella forsythia. By the multiple regression analysis, only P. intermedia had statistically significant co-relation with fluorescence intensities. All of the fluorescent dental plaque contained P. intermedia m. In contrast, 28% of non-fluorescent plaques contained P. intermedia. To check the fluorescence dental plaque in the oral cavity could be the simple chair-side screening of the mature dental plaque before examining the periodontal pathogens especially P. intermedia by the PCR method.

    Prevotella intermedia and Prevotella nigrescens, which are often isolated from periodontal sites, were once considered two different genotypes of P. intermedia. Although the genomic sequence of P. intermedia was determined recently, little is known about the genetic differences between P. intermedia and P. nigrescens. The subtractive hybridization technique is a powerful method for generating a set of DNA fragments differing between two closely related bacterial strains or species. We used subtractive hybridization to identify the DNA regions specific to P. intermedia ATCC 25611 and P. nigrescens ATCC 25261. Using this method, four P. intermedia ATCC 25611-specific and three P. nigrescens ATCC 25261-specific regions were determined. From the species-specific regions, insertion sequence (IS) elements were isolated for P. intermedia. IS elements play an important role in the pathogenicity of bacteria. For the P. intermedia-specific regions, the genes adenine-specific DNA-methyltransferase and 8-amino-7-oxononanoate synthase were isolated. The P. nigrescens-specific region contained a Flavobacterium psychrophilum SprA homologue, a cell-surface protein involved in gliding motility, Prevotella melaninogenica ATCC 25845 glutathione peroxide, and Porphyromonas gingivalis ATCC 33277 leucyl-tRNA synthetase. The results demonstrate that the subtractive hybridization technique was useful for distinguishing between the two closely related species. Furthermore, this technique will contribute to our understanding of the virulence of these species. 2009 Elsevier Ltd. All rights reserved.

    To investigate the genetic relationship of Ephedra intermedia from different habitats in Gansu. The genetic diversity and genetic relationship of E. intermedia from different habitats in Gansu were studied by ISSR molecular marker technique. Twelve ISSR primers were selected from 70 ISSR primers and used for ISSR amplification. Total 112 loci were amplified, in which 81 were polymorphic loci, the average percentage of polymorphie bands (PPB) was 72.32%. Clustering results indicated that the wild species and cultivating species were clustered into different group. The wild species, which had closer distance, were clustered into a group. E. intermedia of different habitats in Gansu have rich genetic diversities among species, it is the reason that E. intermedia has strong adaptability and wide distribution. Further, the genetic distance of E. intermedia is associated with geographical distance, the further distance can hinder the gene flow.

    Pellet formation of filamentous fungi in submerged culture is an imperative topic of fermentation research. In this study, we report for the first time the growth of filamentous ascomycete fungus, Neurospora intermedia in its mycelial pellet form. In submerged culture, the growth morphology of the fungus was successfully manipulated into growing as pellets by modifying various cultivation conditions. Factors such as pH (2.0-10.0), agitation rate (100-150 rpm), carbon source (glucose, arabinose, sucrose, and galactose), the presence of additive agents (glycerol and calcium chloride) and trace metals were investigated for their effect on the pellet formation. Of the various factors screened, uniform pellets were formed only at pH range 3.0-4.0, signifying it as the most influential factor for N. intermedia pellet formation. The average pellet size ranged from 2.38 ± 0.12 to 2.86 ± 0.38 mm. The pellet formation remained unaffected by the inoculum type used and its size showed an inverse correlation with the agitation rate of the culture. Efficient glucose utilization was observed with fungal pellets, as opposed to the freely suspended mycelium, proving its viability for fast-fermentation processes. Scale up of the pelletization process was also carried out in bench-scale airlift and bubble column reactors (4.5 L).

    The pars intermedia is an area of the vulva that has been inconsistently described in the literature. We conducted anatomic studies to better describe the tissues and vascular structures of the pars intermedia and proposed a functional rationale of the pars intermedia in the female sexual response. Nine cadaveric vulvectomy specimens were used. Each was serially sectioned and stained with hematoxylin and eosin and Masson's trichrome. Histologic ultrastructural description of the pars intermedia. The pars intermedia contains veins traveling longitudinally in the angle of the clitoris, supported by collagen-rich stromal tissues. These veins drain the different vascular compartments of the vulva, including the clitoris, the bulbs, and labia minora; also, the interconnecting veins link the different vascular compartments. The pars intermedia is not composed of erectile tissue, distinguishing it from the erectile tissues of the corpora cavernosa of the clitoris as well as the corpus spongiosum of the clitoral (vestibular) bulbs. The venous communications of the pars intermedia, linking the erectile tissues with the other vascular compartments of the vulva, appear to provide the anatomic basis for a coordinated vascular response during female sexual arousal. © 2012 International Society for Sexual Medicine.

    A study was conducted to identify volatile organic compounds or volatiles produced by Candida intermedia strain C410 using gas chromatography-mass spectrometry, and to determine efficacy of the volatiles of C. intermedia in suppression of conidial germination and mycelial growth of Botrytis cinerea and control of Botrytis fruit rot of strawberry. Results showed that, among 49 volatiles (esters, alcohols, alkenes, alkanes, alkynes, organic acids, ketones, and aldehydes) identified from C. intermedia cultures on yeast extract peptone dextrose agar, two compounds, 1,3,5,7-cyclooctatetraene and 3-methyl-1-butanol, were the most abundant. Synthetic chemicals of 1,3,5,7-cyclooctatetraene; 3-methyl-1-butanol; 2-nonanone; pentanoic acid, 4-methyl-, ethyl ester; 3-methyl-1-butanol, acetate; acetic acid, pentyl ester; and hexanoic acid, ethyl ester were highly inhibitory to conidial germination and mycelial growth of B. cinerea. Inhibition of conidial germination and mycelial growth of B. cinerea by volatiles of C. intermedia was also observed. Meanwhile, results showed that incidence and severity of Botrytis fruit rot of strawberry was significantly (P intermedia cultures or C. intermedia-infested strawberry fruit. These results suggest that the volatiles of C. intermedia C410 are promising biofumigants for control of Botrytis fruit rot of strawberry.

    Science.gov (United States)

    Demkiv, O. T.; Kyjak, N. Y.; Khorkavtsiv, Y. D.; Kit, N. A.

    The protonemata development proceeds in the process of gradual differentiation of growing apical cells and intercalar cells the shortened lateral branches of the latters being transformed into three-dimensional gametophore buds (Demkiv et al., 1991). Normal course of plant development needs favourable external conditions. Sometimes, however, external environment agents can accelerate the development of organism. So, apical protonema cells of darkgrown gravitropic P. intermedia differentiate gametophore-buds in light of low intensity (Ripetskyj, 1999). We investigate the influence of gravistimulation on bud formation in haploid and diploid P. intermedia protonema. Diploid protonema was found to react on light weaker than haploid one. Under the influence of light the darkgrown apical cells and lateral branches of haploid protonema were directly transformed into buds, while in diploid protonema at first the formation of bundles of rhizoid type filaments takes place on the tips of caulonema and buds appeared in center of such bundles. The participation of gravity in gametophore bud formation was assessed by clinorotating protonema in darkness. Being illuminated such protonema also developed buds quickly the latters being formed along all stolon. It can be suggested that at 1g the growth zone of apical cells actively attract inductors of bud formation. During clinorotation the inductors probably are transferred much more slower than under stationary state and that is why the buds arised not only at the tips of stolons but along all their length. It is known that gametophore bud formation can be stimulated by exogenous phytohormones. As M. Bopp (1980) has shown, that kinetin selectively promotes bud formation on moss protonema. Our observations have shown 0,5 -- 50 μ M of kinetin stimulate the bud formation on diploid aposporic protonema much more effectively that on haploid one. It can be concluded that the amount of endogenous cytokinins in haploid protonemal cells is

    Full Text Available La enfermedad mental afecta no solo al paciente sino también a su familia, dificulta la comunicación intrafamiliar, puede generar patologías adicionales en los familiares y todo ello empeorar la evolución del trastorno. Las terapias familiares de tipo psicoeducativo mejoran el pronóstico de la enfermedad y además previenen la aparición de otros trastornos en los familiares. Los elementos más importantes de estas intervenciones son la psicoeducación sobre el trastorno, el re-establecimiento de una relación sana entre paciente-familia, el establecimiento de límites, la mejora de la comunicación familiar y el establecimiento de relaciones con la red social extensa, para evitar el aislamiento tanto de la familia como del paciente. Las intervenciones mixtas, individuales y familiares, han demostrado ser muy útiles en el caso de los trastornos de personalidad, en concreto en el Trastorno Límite de Personalidad (TLP.

  16. Paraspinal extramedullary hematopoiesis in patients with thalassemia intermedia.

    2010-06-01

    Ineffective erythropoiesis in patients with thalassemia intermedia drives extramedullary hematopoietic tumor formation in several parts of the body. Paraspinal involvement has received increasing attention due to the associated morbidity secondary to spinal cord compression. Although the history and physical examination may help narrow the differential diagnosis, radiographic imaging remains essential to confirm the existence of hematopoietic tissue. Characteristic appearance has been observed mainly on magnetic resonance imaging. Several treatment options have been described, including transfusion therapy, laminectomy, radiotherapy, and the use of fetal hemoglobin inducing agents that decrease the hematopoietic drive. However, the ideal management scheme remains controversial. Until large prospective trials evaluate the efficacy and safety of the available treatment options, both in single and in combination therapy, an individualized approach should be entertained.

    Linalool acetate, one of the major constituent of several essential oils, is heat-labile and decomposes upon exposure to the high injector temperature during gas chromatography. Here we report the development of an improved method for detection of this compound by gas chromatography mass spectrometry (GCMS) using cold on-column injection of the sample. By using this sensitive method, it has been demonstrated that a lavandin (L. x intermedia) mutant accumulates trace quantities of linalool acetate and camphor and higher amounts of cineole and borneol compared to its parent. This plant, which very likely carries a point mutation in one or more of the genes involved in essential oil production, provides a unique tool for investigating regulation of essential oil biogenesis in plants.

    A broth microdilution method was used to determine the antimicrobial susceptibility of 20 Brachyspira intermedia isolates obtained from different layer flocks in Belgium and The Netherlands between 2008 and 2010. The antimicrobial agents used were tylosin, tilmicosin, tiamulin, valnemulin, doxycycline, and lincomycin. The minimal inhibitory concentration (MIC) distribution patterns of tylosin, tilmicosin, lincomycin, and doxycycline were bimodal, demonstrating acquired resistance against doxycycline in three strains, against the macrolides in two strains, and against lincomycin in one strain. The MICs of tiamulin and valnemulin showed a monomodal distribution, but with tailing toward the higher MIC values, possibly suggesting low-level acquired resistance in six isolates. Sequencing revealed a G1058C mutation in the 16S rRNA gene in all doxycycline-resistant strains. The strain resistant to tylosin, tilmicosin, and lincomycin had an A2058T mutation in the 23S rRNA gene.

    2013-03-01

    Full Text Available Thalassemia intermedia is a genetically diverse group of diseases that is the result of an imbalance in the production of the alpha and beta chains with ensuing chronic hemolysis, ineffective erythropoiesis, and iron overload.Resulting complications include bone changes, hypercoagulability, and end-organ damage due to iron overload. This decade has witnessed major breakthroughs in the management of thalassemia. In this article, we examine these novelties in therapy including iron chelation therapy, stem cell transplant, and gene therapy.Iron chelation therapy has been revolutionized with the advent of deferasirox, a once-daily oral iron chelator, that has been shown to be safe and efficacious.Gene therapy was also at the core of this revolution with the discovery of novel gene elements and viral vectors allowing for better control and improved outcomes.

    Thalassaemia is a genetic disease of the haemoglobin protein in red blood cells. It is classified into thalassaemia minor, intermedia and major, depending on the severity of the disease and the genetic defect. Thalassaemia major and intermedia require frequent blood transfusions to compensate for the lack of well-functioning red blood cells, although this need is significantly less in thalassaemia intermedia.Damaged or defective red blood cells are normally eliminated in the spleen. In people with thalassaemia there is a large quantity of defective red blood cells which results in an enlarged hyperfunctioning spleen (splenomegaly). Removal of the spleen may thus prolong red blood cell survival by reducing the amount of red blood cells removed from circulation and may ultimately result in the reduced need for blood transfusions. To assess the efficacy and safety of splenectomy in people with beta-thalassaemia major or intermedia. We searched the Cochrane Cystic Fibrosis and Genetic Disorders Review Group's Haemoglobinopathies Trials Register, compiled from searches of electronic databases and the handsearching of journals and conference abstract books. We also searched the reference lists of relevant articles and reviews.Date of the most recent search: 25 April 2016. We included randomised controlled studies and quasi-randomised controlled studies of people of any age with thalassaemia major or intermedia, evaluating splenectomy in comparison to conservative treatment (transfusion therapy and iron chelation) or other forms of splenectomy compared to each other (laparoscopic, open, radio-frequency). Two authors independently selected and extracted data from the single included study using a customised data extraction form and assessed the risk of bias. One study, including 28 participants was included in the review; the results were described, primarily, in a narrative manner. The study assessed the feasibility of splenectomy using laparoscopy in comparison to open

    Full Text Available The objective of this research was to evaluate, in laboratory, the development of Lutzomyia intermedia and Lutzomyia longipalpis (Diptera: Psychodidae: Phlebotominae larvae, vectors of leishmaniasis in Brazil, in the following diets: industrialized food for rabbits, dogs, hamsters and aquarium fishes, besides liver powder, cooked lettuce, wheat germ, beer yeast, oat, wheat bran and a diet denominated aged food. Except wheat bran for L. intermedia, all diets provided adequate development for both species, which showed that any of them can be used in laboratory insectaries for these insects. L. intermedia showed better development with most nutritious diets and both species presented better development with aged food. Fungi as an additional nutrient source for L. intermedia and L. longipalpis is suggested.

    The genus Kluyvera comprises potential pathogens that can cause many infections. This study reports a Kluyvera intermedia strain (FOSA7093) from a pancreatic cyst specimen from a long-term hospitalised patient. Whole-genome sequencing (WGS) of the K. intermedia isolate was performed and the strain was reported as sensitive to Danish-registered antibiotics although it had a fosA-like gene in the genome. There were nine contigs that aligned to a plasmid, and these contigs contained several heavy metal resistance gene homologues. Furthermore, a prophage was discovered in the genome. WGS represents an efficient tool for monitoring Kluyvera spp. and its role as a reservoir of multidrug resistance. Therefore, this susceptible K. intermedia genome has many characteristics that allow comparison of resistant K. intermedia that might be discovered in the future.

    To determine the sensitivity of Porphyromonas gingivalis, Prevotella intermedia, and Tannerella forsythia to triclosan, and determine if these bacteria develop resistance to triclosan upon prolonged exposure. Susceptibility to triclosan was tested against three periodontal pathogens P. gingivalis, P. intermedia, and T. forsythia. Escherichia coli strains sensitive and resistant to triclosan were used as biological controls to confirm the efficacy of triclosan in the assays. Agar plates were prepared locally with vitamin K and hemin-supplemented medium. Porphyromonas gingivalis and P. intermedia did not grow on plates containing ≥ 2 μg/ml triclosan, while T. forsythia did not grow on ≥ 1.66 μg/ml. Colonies of P. intermedia resistant to triclosan developed after prolonged incubation at 2 μg/ml, but this resistance disappeared during subculture in the absence of triclosan. No significant resistance to triclosan was detected for these species. Dental products containing triclosan can be beneficial in controlling periodontal disease.

    To investigate the effects of an egg yolk-derived immunoglobulin (IgY) specific to Prevotella intermedia in vitro and in vivo. An IgY specific to P. intermedia was produced by immunizing hens with formaldehyde-inactivated P. intermedia and showed high titres when subjected to an ELISA. The obtained IgY inhibited the growth of P. intermedia in a dose-dependent manner at concentrations from 1 to 20 mg ml(-1) in Center for Disease Control and Prevention liquid medium. Forty rats were challenged with P. intermedia on gingivae and then randomly divided into four groups, which were syringed respectively with phosphate-buffered saline, 1 mg ml(-1) of tinidazole, 20 mg ml(-1) of nonspecific IgY and 20 mg ml(-1) of the IgY specific to P. intermedia at a dosage of 300 μl per day. Gingival index (GI), plaque index (PI), bleeding on probing (BOP), counts of white blood cell (WBC) and histopathological slide of the gums were measured after treatment for 15 days. The gingivitis rats treated with the IgY specific to P. intermedia showed significantly decreased GI, PI, BOP and WBC (P intermedia-mediated gingivitis. A new immunoglobulin specific to P. intermedia was developed from egg yolk. This specific IgY can dose-dependently inhibit the growth of P. intermedia and protect rats from gingivitis induced by P. intermedia. The new IgY has potential for the treatment of P. intermedia-mediated gingivitis. © 2013 The Society for Applied Microbiology.

    Polyphosphate (polyP) has gained a wide interest in the food industry due to its potential as a decontaminating agent. In this study, we examined the effect of sodium tripolyphosphate (polyP3; Na5P3O10) against planktonic and biofilm cells of Prevotella intermedia, a major oral pathogen. The MIC of polyP3 against P. intermedia ATCC 49046 determined by agar dilution method was 0.075%, while 0.05% polyP3 was bactericidal against P. intermedia in time-kill analysis performed using liquid medium. A crystal violet binding assay for the assessment of biofilm formation by P. intermedia showed that sub-MICs of polyP3 significantly decreased biofilm formation. Under the scanning electron microscope, decreased numbers of P. intermedia cells forming the biofilms were observed when the bacterial cells were incubated with 0.025% or higher concentrations of polyP3. Assessment of biofilm viability with LIVE/DEAD staining and viable cell count methods showed that 0.05% or higher concentrations of polyP3 significantly decreased the viability of the preformed biofilms in a concentration-dependent manner. The zone sizes of alpha-hemolysis formed on horse blood agar produced by P. intermedia were decreased in the presence of polyP3. The expression of the genes encoding hemolysins and the genes of the hemin uptake (hmu) locus was downregulated by polyP3. Collectively, our results show that polyP is an effective antimicrobial agent against P. intermedia in biofilms as well as planktonic phase, interfering with the process of hemin acquisition by the bacterium.

    We established a typing system for Prevotella intermedia and Prevotella nigrescens using the combination of PCR ribotyping and arbitrarily primed PCR (AP-PCR) fingerprinting and applied this system to the study of intrafamilial incidence of these species in the oral cavity. PCR ribotyping followed by subtyping by AP-PCR fingerprinting was applied to each type strain of P. intermedia and P. nigrescens and 54 isolates (32 isolates of P. intermedia and 24 isolates of P. nigrescens) from extraoral infections, resulting in an excellent discriminatory power (discrimination index, 0.99) for both species. A total of 18 subjects from six families, with the subjects from each family comprising the mother, the father, and a child who had subclinical early-stage to moderate adult periodontitis or simple gingivitis and who carried P. intermedia or P. nigrescens, or both, were enrolled in the study of intrafamilial carriage. When 20 colonies per specimen of subgingival plaque, if available, were picked from primary culture, 115 P. intermedia and 178 P. nigrescens isolates were recovered from the 18 subjects. Among the subjects studied, family members shared the same subtype strain(s) but non-family members did not. Multiple subtypes were found in 8 (57%) of the 14 P. nigrescens-positive subjects but in only 3 (27%) of the 11 P. intermedia-positive subjects; the difference was, however, not statistically significant (P = 0.14). These results suggest that the combination of PCR ribotyping and AP-PCR fingerprinting is well suited for the epidemiological study of P. intermedia and P. nigrescens and that each family seems to carry a distinct subtype(s) of these species.

    2009-01-01

    The species Yersinia intermedia is a member of the genus Yersinia which belongs to the Enterobacteriaceae family. This species is divided into eight biotypes, according to Brenner's biotyping scheme. This scheme relies on five tests (utilization of Simmons citrate and acid production from d-melibiose, d-raffinose, α-methyl-d-glucoside [αMG], and l-rhamnose). The collection of the French Yersinia Reference Laboratory (Institut Pasteur, Paris, France) contained 44 strains that were originally identified as Y. intermedia but whose characteristics did not fit into the biotyping scheme. These 44 strains were separated into two biochemical groups: variant 1 (positive for acid production from l-rhamnose and αMG and positive for Simmons citrate utlization) and variant 2 (positive for acid production from l-rhamnose and αMG). These atypical strains could correspond to new biotypes of Y. intermedia, to Y. frederiksenii strains having the atypical property of fermenting αMG, or to new Yersinia species. These strains did not exhibit growth or phenotypic properties different from those of Y. intermedia and Y. frederiksenii and did not harbor any of the virulence traits usually found in pathogenic species. DNA-DNA hybridizations performed between one strain each of variants 1 and 2 and the Y. intermedia and Y. frederiksenii type strains demonstrated that these variants do belong to the Y. intermedia species. We thus propose that Brenner's biotyping scheme be updated by adding two new biotypes: 9 (for variant 1) and 10 (for variant 2) to the species Y. intermedia. PMID:19494062

    The gravitropism of caulonemata of Pottia intermedia is described and compared with that of other mosses. Spore germination produces primary protonemata including caulonemata which give rise to buds that form the leafy moss plant, the gametophore. Primary caulonemata are negatively gravitropic but their growth and the number of filaments are limited in the dark. Axenic culture of gametophores results in the production of secondary caulonemata that usually arise near the leaf base. Secondary protonemata that form in the light are agravitropic. Secondary caulonemata that form when gametophores are placed in the dark for several days show strong negative gravitropism and grow well in the dark. When upright caulonemata are reorientated to the horizontal or are inverted, upward bending can be detected after 1 h and caulonemata reach the vertical within 1-2 d. Clear amyloplast sedimentation occurs 10-15 minutes after horizontal placement and before the start of upward curvature. This sedimentation takes place in a sub-apical zone. Amyloplast sedimentation also takes place along the length of upright and inverted Pottia protonemata. These results support the hypothesis that amyloplast sedimentation functions in gravitropic sensing since sedimentation occurs before gravitropism in Pottia and since the location and presence of a unique sedimentation zone is conserved in all four mosses known to gravitropic protonomata.

    Full Text Available Este artículo describe el proceso de desafiliación (Castel, 1995 juvenil, tomando como caso de estudio un barrio desfavorecido de Madrid. A través de una metodología etnográfica examina el efecto de las estructuras intermedias (la familia, la comunidad local y las asociaciones civiles en la reinserción educativa y laboral de los jóvenes de origen marroquí, dominicano y ecuatoriano. La investigación señala como elemento más determinante de dicha reinserción el capital humano de los padres, confi rmando los hallazgos de la sociología de la educación (Bourdieu, 1970. Además, advierte del doble efecto (positivo y negativo que provoca la influencia de las comunidades étnicas en los jóvenes más vulnerables y demuestra el rol crucial que cumple el tejido asociativo. Estas organizaciones, herederas de las movilizaciones de los años 70, tienen la capacidad de abrir nuevas vías de inserción a través de la colaboración con las administraciones, los grupos étnicos y las familias.

    Alterations in the quantity and quality of biofilms at gingival margin are considered to play a role in the initiation and development of pregnancy-related gingivitis. Prevotella intermedia sensu lato is able to consume estradiol, the major sex hormone secreted during pregnancy, in the absence of vitamin K. The aim of the study was to examine the effect of estradiol on the planktonic growth, coaggregation, polysaccharide production, and biofilm formation of the P. intermedia group bacteria, namely P. intermedia, Prevotella nigrescens, and Prevotella pallens. In all experiments, the type strain (ATCC) and a clinical strain (AHN) of P. intermedia, P. nigrescens, and P. pallens were incubated with the concentrations of 0, 30, 90, and 120 nmol/L of estradiol. Planktonic growth was assessed by means of the colony forming unit method, while coaggregation and biofilm formation were assessed by spectrophotometric methods. In the determination of protein and polysaccharide levels, the Bradford and phenol-sulfuric acid methods were used, respectively. P. pallens AHN 9283 and P. nigrescens ATCC 33563 increased their numbers at planktonic stage with increasing estradiol concentrations. In 48-h biofilm tests, elevated protein levels were found for both strains of P. intermedia, and the strains P. nigrescens ATCC 33563 and P. pallens AHN 9283 in the presence of estradiol. The P. intermedia strains also increased the levels of polysaccharide formation in the biofilm. Coaggregation of the P. intermedia group organisms with Fusobacterium nucleatum was enhanced only in P. intermedia AHN 8290. In conclusion, our in vitro experiments indicate that estradiol regulates planktonic growth, coaggregation, polysaccharide production, and biofilm formation characteristics of P. intermedia, P. nigrescens, and P. pallens differently. These results may, at least partly, explain the differences seen in their contribution to the pathogenesis of pregnancy-related gingivitis

    Full Text Available Brown spiders (Loxosceles spp. are venomous arachnids, successfully adapted to urban habitats in Brazil. Loxoscelism became a serious public health problem in Paraná State, especially at the capital Curitiba, where the most abundant species is Loxosceles intermedia. Hemidactylus mabouia (Gekkonidae lizards are synanthropic predators of arthropods. In this paper, we describe the predatory behavior of the Tropical House Gecko H. mabouia on L. intermedia under laboratory conditions. Twelve geckos were observed, and all of them fed on brown spiders (n=123 observations. The attack consisted of a fast run followed by one bite on the spider’s abdomen or legs. The geckos did not attack L. intermedia anterior body parts, probably due to the fangs present in this region. Two Hemidactylus individuals were killed by L. intermedia bites: during a predatory encounter, and by an induced bite on a restrained lizard. The observations summarized in this paper show that H. mabouia could be used in the biological control of Loxosceles populations in human dwellings. However, additional field studies are necessary to quantify the impact of H. mabouia predation on urban populations of L. intermedia and other species of the same genus.

    Prevotella intermedia, a major periodontal pathogen, is increasingly implicated in human respiratory tract and cystic fibrosis lung infections. Nevertheless, the specific mechanisms employed by this pathogen remain only partially characterized and poorly understood, largely due to its total lack of genetic accessibility. Here, using Single Molecule, Real-Time (SMRT) genome and methylome sequencing, bisulfite sequencing, in addition to cloning and restriction analysis, we define the specific genetic barriers to exogenous DNA present in two of the most widespread laboratory strains, P. intermedia ATCC 25611 and P. intermedia Strain 17. We identified and characterized multiple restriction-modification (R-M) systems, some of which are considerably divergent between the two strains. We propose that these R-M systems are the root cause of the P. intermedia transformation barrier. Additionally, we note the presence of conserved Clustered Regularly Interspaced Short Palindromic Repeat (CRISPR) systems in both strains, which could provide a further barrier to exogenous DNA uptake and incorporation. This work will provide a valuable resource during the development of a genetic system for P. intermedia, which will be required for fundamental investigation of this organism's physiology, metabolism, and pathogenesis in human disease.

    2011-05-01

    Full Text Available Abstract Background Acoustic signals are part of the courtship of many insects and they often act as species-specific signals that are important in the reproductive isolation of closely related species. Here we report the courtship songs of the sand fly Lutzomyia (Nyssomyia intermedia, one of the main vectors of cutaneous leishmaniasis in Brazil. Findings Recordings were performed using insects from three localities from Eastern Brazil: Posse and Jacarepaguá in Rio de Janeiro State and Corte de Pedra in Bahia State. The three areas have remnants of the Brazilian Atlantic forest, they are endemic for cutaneous leishmaniasis and L. intermedia is the predominant sand fly species. We observed that during courtship L. intermedia males from all populations produced pulse songs consisting of short trains. No significant differences in song parameters were observed between the males of the three localities. Conclusions L. intermedia males produce acoustic signals as reported for some other sand flies such as the sibling species of the Lutzomyia longipalpis complex. The lack of differences between the males from the three localities is consistent with previous molecular studies of the period gene carried out in the same populations, reinforcing the idea that L. intermedia is not a species complex in the studied areas and that the three populations are likely to have similar vectorial capacities.

    Full Text Available La heterogeneidad del suelo influye ampliamente en el contenido de humedad, dificultando la precisa determinación de este parámetro en estudios con fines hidrológicos y ecológicos que requieren de mediciones continuas y representativas para escalas intermedias (~1 km. En este contexto un sensor de neutrón de rayo cósmico The COsmic-ray Soil Moisture Observing System (COSMOS permite cuantificar humedad del suelo de manera continua y a escalas espaciales de cientos de metros. El objetivo de este estudio fue evaluar un esquema de calibración para un sensor COSMOS CRS-1000. El estudio se realizó en una sabana de zacate buffel (Pennisetum ciliare en Rayón Sonora, México. En este sitio se instaló el COSMOS CRS-1000 y para su calibración se realizaron muestreos de suelo en dos etapas. A estas muestras se les determinó el contenido de humedad y su densidad aparente por técnicas gravimétricas. Con el contenido de humedad de estas muestras, expresado en términos volumétricos, se obtuvo por aproximación el parámetro de calibración para el COSMOS CRS-1000. El valor obtenido para este parámetro fue de 4121 conteos por hora (tasa de conteo del neutrón sobre suelo. Con este valor se realizó la corrección a los valores estimados originalmente por el sensor COSMOS CRS-1000. Al realizar esta corrección, se observó un incremento en el contenido de humedad del suelo de 1 a 2 % con respecto a los valores estimados con el COSMOS CRS-1000 en todo el periodo de análisis. A pesar de la variabilidad espacial en el contenido de humedad del suelo bajo estudio, se observó que el sensor COSMOS CRS-1000 tiene la capacidad de proveer estimaciones razonables del contenido de la humedad del suelo de manera continua a una profundidad de 0 a 40 cm, en una superficie de alrededor de 30 ha.

    Althaus, L. G.; Benvenuto, O. G.

    Numerosas observaciones realizadas particularmente en los últimos dos años parecen confirmar que las enanas blancas (EB) de helio de masa baja e intermedia son el resultado de la evolución de sistemas binarios cercanos. Con el objeto de realizar una adecuada interpretación de estos objetos son necesarios modelos de EBs de helio lo más detallado posibles. En este estudio presentamos cálculos detallados de la evolución de EBs de helio con masas entre M=0.1Msolar y M=0.5Msolar a intervalos de 0.05Msolar . Para ello, hemos tenido en cuenta los efectos de temperatura finita mediante un código de evolución estelar lo más actualizado posible. En particular, el transporte de energía es descripto en el marco del nuevo modelo para la convección turbulenta desarrollado por Canuto - Mazzitelli. Además hemos considerado la nueva ecuación de estado para plasmas de helio de Saumon et al. y nuevas opacidades radiativas OPAL. Las pérdidas por neutrinos fueron asimismo tenidas en cuenta. Excepto para las EBs más masivas, nuestros modelos iniciales están ubicados en las cercanías de la correspondiente línea de Hayashi para configuraciones de helio. Nuestros resultados muestran que existe una región prohibida en el diagrama observacional HR donde ninguna EB de helio puede encontrarse. Dicha región es para log{(L/Lsolar )}>= -0.25 and log{Teff} >= 4.45. Hemos encontrado también que los tracks evolutivos en el diagrama HR en el dominio de alta luminosidad (pre - EB) son fuertemente afectados por la eficiencia convectiva y que las pérdidas por neutrinos son importantes en los modelos más masivos. Finalmente hemos analizado la estructura de la zona convectiva externa encontrando que la teoría de Canuto - Mazzitelli conduce a un perfil convectivo muy diferente del dado por cualquier versión de la popular teoría de la mixing length. Si bién este comportamiento es decisivo en el contexto de las inestabilides pulsacionales, los radios y gravedades superficiales de

    Full Text Available Background: Dental caries with necrotic pulp is a multifactorial disease that attacks enamel involving tooth pulp. The anaerobic bacteria infection in the pulp chamber could induce the formation of periapical granuloma. However, the presence of the most frequently anaerobic bacteria identified in apical periodontitis, Porphyromonas gingivalis and Prevotella intermedia, in periapical granuloma have not been confirmed. Purpose: The aims of study were to determine the presence of Porphyromonas gingivalis and Prevotella intermedia in dental caries with necrotic pulp and to determine its relation to periapical granuloma. Methods: Thirty-six patients of dental caries with necrotic pulp in Dr. Moewardi General Hospital in Surakarta, Indonesia were involved and classified into two groups, the group of patients with periapical granuloma and the group of patients without periapical granuloma. The caries tooth was extracted, and the chronic periapical tissue was swabbed and cultured on blood agar medium in anaerobic condition. The bacterial DNA was extracted from the positive cultures and subjected for Polymerase Chain Reaction (PCR. Results: Periapical granuloma was more likely found in women (OR 5.5, 95% CI=1.277-23.693; RR 2.5, 95% CI= 1.025-6.100. Black colonies bacteria were associated with periapical granuloma (OR 2.2, 95% CI=0.517-9.594; RR 1.5, 95% CI=0.655-3.623. Porphyromonas gingivalis and Prevotella intermedia were detected in group with or without periapical granuloma, however, only Prevotella intermedia was associated with periapical granuloma (OR 1.6, 95% CI=0.418-5.903; RR 1.3, 95% CI=0.653-2.393. Conclusion: The presence of Porphyromonas gingivalis and Prevotella intermedia in periapical granuloma were confirmed, however, only Prevotella intermedia were associated with periapical granuloma.Latar belakang: Karies gigi dengan pulpa nekrosis adalah penyakit multifaktorial yang menyerang enamel hingga ruang pulpa gigi.

    The Digital Distribution of Advertising for Publications (DDAP) is a graphic arts industry prototype of Electronic Intermedia Publishing (EIP). EIP is a strategic, multi- industrial concept that seeks to enable the capture and input of volumes of data (i.e., both raster and object oriented data -- as well as the latter's antecedent which is vector data -- color data and black-and-white data) from a multiplicity of devices; then flowing, controlling, manipulating, modifying, storing, retrieving, transmitting, and shipping, that data through an industrial process for output to a multiplicity of output devices (e.g., ink on paper, toner on paper, bits and bytes on CD ROM, Internet, Multimedia, HDTV, etc.). As the technical requirements of the print medium are among the most rigorous in the Intermedia milieu the DDAP prototype addresses some of the most challenging issues faced in Electronic Intermedia Publishing (EIP).

    Full Text Available Until very recently, phenomena like delinquency were only considered dysfunctions of the system. However, nowadays this phenomenon has become inherent to its way of functioning. This dynamic is influenced by factors such as the increasing polarization of developed economies or the enormous masses of displaced people, due to either economic or political reasons, from developing countries who, in rich countries, often fall in situations of precariousness. In the following text we will see how all these pieces are interrelated in an intermediate city, and we will analyse the fluctuation of violent or intimidating thefts, as well as the most common places where these are committed.Si hasta hace bien poco se había considerado que fenómenos como la delincuencia no eran más que disfunciones del sistema, en el mundo en el que vivimos este fenómeno se ha convertido en inherente a su manera de funcionar. Influyen en esta dinámica factores como la polarización creciente de las economías desarrolladas o las ingentes masas de desplazados, ya sea por razones económicas o políticas, de países en vías de desarrollo que, en los países ricos, caen las más de las veces en la precariedad. En el texto que sigue se verá como se engarzan todas estas piezas en una ciudad intermedia y se analizará la fluctuación de los robos con violencia o intimidación, así como los lugares típicos en los que éstos se cometen.DOWNLOAD THIS PAPER FROM SSRN: http://ssrn.com/abstract=1739302

    Full Text Available Periodontitis is an inflammatory disease of the supporting structures of the teeth caused by, among other pathogens, Prevotella intermedia. Many strains of P. intermedia are resistant to killing by the human complement system, which is present at up to 70% of serum concentration in gingival crevicular fluid. Incubation of human serum with recombinant cysteine protease of P. intermedia (interpain A resulted in a drastic decrease in bactericidal activity of the serum. Furthermore, a clinical strain 59 expressing interpain A was more serum-resistant than another clinical strain 57, which did not express interpain A, as determined by Western blotting. Moreover, in the presence of the cysteine protease inhibitor E64, the killing of strain 59 by human serum was enhanced. Importantly, we found that the majority of P. intermedia strains isolated from chronic and aggressive periodontitis carry and express the interpain A gene. The protective effect of interpain A against serum bactericidal activity was found to be attributable to its ability to inhibit all three complement pathways through the efficient degradation of the alpha-chain of C3 -- the major complement factor common to all three pathways. P. intermedia has been known to co-aggregate with P. gingivalis, which produce gingipains to efficiently degrade complement factors. Here, interpain A was found to have a synergistic effect with gingipains on complement degradation. In addition, interpain A was able to activate the C1 complex in serum, causing deposition of C1q on inert and bacterial surfaces, which may be important at initial stages of infection when local inflammatory reaction may be beneficial for a pathogen. Taken together, the newly characterized interpain A proteinase appears to be an important virulence factor of P. intermedia.

    Extramedullary hematopoiesis (EMH) is the production of blood cell precursors outside the bone marrow that occur in various hematological diseases. In patients with thalassemia intermedia, ineffective erythropoiesis drives compensatory EMH in the liver, pancreas, pleura, spleen, ribs and spine. We describe a patient with thalassemia intermedia who presented with acute neurological symptoms caused by paraspinal EMH, which responded well to combination therapy of steroid, hypertransfusion, laminectomy and excision of pseudotumor and hydroxyurea therapy to boost the formation of fetal haemoglobin. Prompt recognition of EMH based on clinical presentation and typical radiological findings should be made. Early treatment is recommended to prevent irreversible damage to the spinal cord.

    There are various clinical symptoms of thalassemia intermedia, and they lie roughly between those of major and minor forms of the disease. Patients with thalassemia intermedia occasionally require blood transfusions. This renders them susceptible to pulmonary arterial hypertension (PAH) syndrome, which is one of the most significant complications in patients with thalassemia intermedia. PAH is more common in in thalassemia intermedia than in thalassemia major, and it may cause cardiac complications in patients who are older than 30. The objective of this study was to estimate the prevalence of PAH in thalassemia intermedia patients so that they can be referred expeditiously for treatment, thereby preventing the complications that occur later. This cross sectional study was conducted under the supervision of hematology department of Mashhad Medical University. Forty-one patients with thalassemia intermedia were examined at the Sarvar Thalassemia and Hemophilia Clinic of Mashhad. Electrocardiography, chest radiography, and echocardiography tests were performed for all of the patients by the same pediatric cardiologist. The data were processed by SPSS software, version 11.5, and the results were analyzed using chi-squared, Student's t, and Mann-Whitney tests. The mean age of the patients was 21.93±8.34. They had been under pediatric heart specialists' constant examination and treatment since their childhood when they were diagnosed with TI, and continue to receive regular follow-up care. The prevalence of pulmonary hypertension was 24% in our study population. In patients with thalassemia intermedia, the left ventricular (LV) mass indices were about 3-5 times higher than would be expected in a normal population. Patients with higher LV mass indices have a greater risk of developing pulmonary hypertension, and those with serum ferritin levels below 1000 ng/ml are less susceptible to diastolic dysfunction. Pulmonary hypertension is common in patients with thalassemia

    The goal of this study was to compare heart function and arrhythmia in clinically asymptomatic patients with beta thalassemia intermedia and beta thalassemia major. In this cross-sectional study, 60 patients with beta thalassemia major and 60 patients with beta thalassemia intermedia who had clinically no symptoms of arrhythmia and clinically normal heart function were evaluated using 24-hour ambulatory electrocardiogram monitoring and echocardiography. For data analysis SPSS ver.20 software was used. A P-value of less than 0.05 was considered statistically significant. The mean age of the beta thalassemia intermedia patients was 24.18 ± 7.9 years and the mean age in beta thalassemia major was 24.38 ± 7.7 years (P>0.05). Premature atrial contractions (PACs) were observed in 14 (23.3%) patients with beta thalassemia intermedia and in 22 (36.6%) beta thalassemia major patients. Premature ventricular contractions (PVCs) were detected in 8 (13.3%) patients in the beta thalassemia intermediate group and 16 (26.6) patients in the beta thalassemia major group, respectively. The left ventricular diastolic dimension, end-diastolic volume, and stroke volume were significantly higher in beta thalassemia intermedia group (Pintermedia group. Both atrial and ventricular arrhythmias were more common in the beta thalassemia major group. Higher end-diastolic volume and stroke volume were detected in the beta thalassemia intermedia group. Pulmonary acceleration time was lower in the beta thalassemia intermedia group, which can be an indicator of higher pulmonary pressure.

    Evidence in the literature suggests that exopolysaccharides (EPS) produced by bacterial cells are essential for the expression of virulence in these organisms. Secreted EPSs form the framework in which microbial biofilms are built. This study evaluates the role of EPS in Prevotella intermedia for the expression of virulence. This evaluation was accomplished by comparing EPS-producing P. intermedia strains 17 and OD1-16 with non-producing P. intermedia ATCC 25611 and Porphyromonas gingivalis strains ATCC 33277, 381 and W83 for their ability to induce abscess formation in mice and evade phagocytosis. EPS-producing P. intermedia strains 17 and OD1-16 induced highly noticeable abscess lesions in mice at 107 colony-forming units (CFU). In comparison, P. intermedia ATCC 25611 and P. gingivalis ATCC 33277, 381 and W83, which all lacked the ability to produce viscous materials, required 100-fold more bacteria (109 CFU) in order to induce detectable abscess lesions in mice. Regarding antiphagocytic activity, P. intermedia strains 17 and OD1-16 were rarely internalized by human polymorphonuclear leukocytes, but other strains were readily engulfed and detected in the phagosomes of these phagocytes. These results demonstrate that the production of EPS by P. intermedia strains 17 and OD1-16 could contribute to the pathogenicity of this organism by conferring their ability to evade the host's innate defence response.

    The aim of this study was to develop Prevotella intermedia-specific PCR primers based on the P. intermedia-specific DNA probe. The P. intermedia-specific DNA probe was screened by inverted dot blot hybridization and confirmed by Southern blot hybridization. The nucleotide sequences of the species-specific DNA probes were determined using a chain termination method. Southern blot analysis showed that the DNA probe, Pig27, detected only the genomic DNA of P. intermedia strains. PCR showed that the PCR primers, Pin-F1/Pin-R1, had species-specificity for P. intermedia. The detection limits of the PCR primer sets were 0.4pg of the purified genomic DNA of P. intermedia ATCC 49046. These results suggest that the PCR primers, Pin-F1/Pin-R1, could be useful in the detection of P. intermedia as well as in the development of a PCR kit in epidemiological studies related to periodontal diseases.

    Both Salvia akiensis and S. lutescens (Lamiaceae) are endemic to Japan. Salvia akiensis was recently described in 2014 in the Chugoku (= SW Honshu) region, and each four varieties of S. lutescens distributed allopatrically. Among varieties in S. lutescens , var. intermedia show a disjunctive distribution in the Kanto (=E Honshu) and Kinki (= W Honshu) regions. Recent field studies of S. lutescens var. intermedia revealed several morphological differences between the Kanto and Kinki populations. Here, I evaluated these differences among Salvia lutescens var. intermedia and its allies with morphological analysis and molecular phylogenetic analyses of nuclear ribosomal DNA (internal and external transcribed spacer regions) and plastid DNA ( ycf1-rps15 spacer, rbcL , and trnL-F ) sequences. Both morphological analysis and molecular phylogenetic analyses showed that S. lutescens var. intermedia from the Kinki region and var. lutescens were closely related to each other. However, var. intermedia from the Kanto region exhibited an association with S. lutescens var. crenata and var. stolonifera, which also grew in eastern Japan, rather than var. intermedia in the Kinki region. These results indicated that S. lutescens var. intermedia is not a taxon with a disjunctive distribution, but a combination of two or more allopatric taxa. Present study also suggested that S. akiensis was most closely related to S. omerocalyx .

    Full Text Available The use of jute matting in managing the invasive aquatic macrophyte species Elodea nuttallii (Planch. H. St. John and Najas marina ssp. intermedia (Wolfg. ex Gorski Casper (Najas intermedia was studied in laboratory experiments and field trials. Four German lakes with predominant population of Najas intermedia or Elodea nuttalli were chosen for the experiment and areas between 150 and 300 m² were covered with jute textile. The effect of the matting on the growth of invasive and non-invasive macrophytes was determined through comparison with control transects. Biodegradable jute matting successfully suppressed the invasive macrophyte Najas intermedia and significantly reduced the growth of Elodea nuttalli in lakes. The results indicate that the capability of the matting to inhibit the growth of Elodea nuttallii and Najas intermedia depends on the mesh size of the jute weaving and that environmental conditions can affect its efficiency. Various indigenous species like Charales or Potamogeton pusillus L. were able to grow through the jute fabric and populate the treated areas. Until the end of the vegetation period, none of the invasive species were able to penetrate the covering and establish a stable population; in fact, in the subsequent year the jute matting affected only the spread of Najas intermedia. Jute matting proved to be an easy-to-use and cheap method to control the growth of Elodea nuttallii and Najas intermedia.

    Full Text Available Some venomous spiders of the genus Loxosceles can reach high population densities inside and around houses. In Brazil, most spider accidents are related to Loxosceles intermedia. Control of loxoscelism should utilize integrated pest management tools, such as vacuum cleaners, to eliminate egg sacs, webs and spiders. The present study tested the efficacy of one type of vacuum cleaner (for professional and domestic use in the control of L. intermedia populations. Cockroaches (Pycnoscelus surinamensis were used in some tests for comparison. Vacuuming using standard accessories or a paper tube resulted in the death of all female (n=60, male (n=60, young (n=60 and just-hatched (n=60 L. intermedia, and all egg sacs (n=5 were destroyed. The removal of the plastic plate present at the bottom of the vacuuming tube inside the machine allowed some spiders to survive the vacuuming process. When kept inside a vacuum bag full of dust and debris, adult females (n=10 survived for 10 days; however, significant mortality was observed among male (n=10 and young individuals (n=10. Addition of cornstarch to the vacuum bag did not affect the spiders (n=20. Vacuum cleaners, such as the one used in the present investigation, are promising tools for integrated management of L. intermedia and other spiders in domestic environments.

    In vivo labeling experiments of Forsythia intermedia plant tissue with [8-(C-14)]- and [9,9-(2)H2,OC(2)H3]coniferyl alcohols revealed that the lignans, (-)-secoisolariciresinol and (-)-matairesinol, were derived from two coniferyl alcohol molecules; no evidence for the formation of the corresponding (+)-enantiomers was found. Administration of (+/-)-[Ar-(H-3)] secoisolariciresinols to excised shoots of F.intermedia resulted in a significant conversion into (-)-matairesinol; again, the (+)-antipode was not detected. Experiments using cell-free extracts of F.intermedia confirmed and extended these findings. In the presence of NAD(P)H and H2O2, the cell-free extracts catalyzed the formation of (-)- secoisolariciresinol, with either [8-(C-14)]- or [9,9-(2)H2,OC(2)H3]coniferyl alcohols as substrates. The (+)- enantiomer was not formed. Finally, when either (-)-[Ar-(H-3)] or (+/-)-[Ar-(H-2)]secoisolariciresinols were used as substrates, in the presence of NAD(P), only (-)- and not (+)-matairesinol formation occurred. The other antipode, (+)-secoisolariciresinol, did not serve as a substrate for the formation of either (+)- or (-)-matairesinol. Thus, in F.intermedia, the formation of the lignan, (-)-secoisolariciresinol, occurs under strict stereochemical control, in a reaction or reactions requiring NAD(P)H and H2O2 as cofactors. This stereoselectivity is retained in the subsequent conversion into (-)-matairesinol, since (+)-secoisolariciresinol is not a substrate. These are the first two enzymes to be discovered in lignan formation.

    The monophyletic duckweeds comprising five genera within the monocot order Alismatales are neotenic, free-floating, aquatic organisms with fast vegetative propagation. Some species are considered for efficient biomass production, for life stock feeding, and for (simultaneous) wastewater phytoremediation. The ancestral genus Spirodela consists of only two species, Spirodela polyrhiza and Spirodela intermedia, both with a similar small genome (~160 Mbp/1C). Reference genome drafts and a physical map of 96 BACs on the 20 chromosome pairs of S. polyrhiza strain 7498 are available and provide useful tools for further evolutionary studies within and between duckweed genera. Here we applied sequential comparative multicolor fluorescence in situ hybridization (mcFISH) to address homeologous chromosomes in S. intermedia (2n = 36), to detect chromosome rearrangements between both species and to elucidate the mechanisms which may have led to the chromosome number alteration after their evolutionary separation. Ten chromosome pairs proved to be conserved between S. polyrhiza and S. intermedia, the remaining ones experienced, depending on the assumed direction of evolution, translocations, inversion, and fissions, respectively. These results represent a first step to unravel karyotype evolution among duckweeds and are anchor points for future genome assembly of S. intermedia.

    Fructanase enzymes hydrolyze the β-2,6 and β-2,1 linkages of levan and inulin fructans, respectively. We analyzed the influence of fructan on the growth of Prevotella intermedia. The growth of P. intermedia was enhanced by addition of inulin, implying that P. intermedia could also use inulin. Based on this finding, we identified and analyzed the genes encoding a putative fructanase (FruA), sugar transporter (FruB), and fructokinase (FruK) in the genome of strain ATCC25611. Transcript analysis by RT-PCR showed that the fruABK genes were co-transcribed as a single mRNA and semi-quantitative analysis confirmed that the fruA gene was induced in response to fructose and inulin. Recombinant FruA and FruK were purified and characterized biochemically. FruA strongly hydrolyzed inulin, with slight degradation of levan via an exo-type mechanism, revealing that FruA is an exo-β-d-fructanase. FruK converted fructose to fructose-6-phosphate in the presence of ATP, confirming that FruK is an ATP-dependent fructokinase. These results suggest that P. intermedia can utilize fructan as a carbon source for growth, and that the fructanase, sugar transporter, and fructokinase proteins we identified are involved in this fructan utilization.

    Patients with cystic fibrosis (CF) with Pseudomonas aeruginosa lung infections produce endobronchial mucus plugs allowing growth of obligate anaerobes including Prevotella spp. Whether obligate anaerobes contribute to the pathophysiology of CF lung disease is unknown. The virulence of Prevotella intermedia and Ps aeruginosa was investigated in vitro and in mice, antibodies against P intermedia in CF sera were assessed and a culture-independent detection method for P intermedia/P nigrescens in CF sputum was tested. P intermedia reached cell numbers of >10(5)->10(7) colony-forming units (CFU)/ml sputum. The majority of patients with CF (16/17; 94.1%) produced antibodies against two immunoreactive antigens of P intermedia. Culture supernatant fluids, collected from 10(9) P intermedia cells, were more cytotoxic to respiratory epithelial cells in vitro and inflammatory in mouse lungs than respective fluids from anaerobically grown Ps aeruginosa, while fluids from aerobically grown Ps aeruginosa had the highest cytotoxicity and inflammation. Both pathological effects were largely reduced when culture supernatant fluids from 10(7) cells of either species were used. P intermedia cells (∼10(6)CFU/lung) did not induce mortality in the agar beads lung infection mouse model, while Ps aeruginosa cells caused death in 30% of mice due to rapid multiplication. A P intermedia/P nigrescens-specific PNA probe was significantly more sensitive than culture-dependent diagnostic assays to detect these strict anaerobes. Ps aeruginosa and P intermedia become significantly virulent in vitro and in vivo when cell numbers exceed 10(8) CFU/lung.

    Phytate is an anti-nutritional factor in plants, which catches the most phosphorus contents and some vital minerals. Therefore, Phytase is added mainly as an additive to the monogastric animals' foods to hydrolyze phytate and increase absorption of phosphorus. Y. intermedia phytase is a new phytase with special characteristics such as high specific activity, pH stability, and thermostability. Our aim was to clone, express, and characterizea codon optimized Y. intermedia phytase gene in E. coli . The Y. intermedia phytase gene was optimized according to the codon usage in E. coli . The sequence was synthesized and sub-cloned in pET-22b (+) vector and transformed into E. coli Bl21 (DE3). The protein was expressed in the presence of IPTG at a final concentration of 1 mM at 30°C. The purification of recombinant protein was performed by Ni 2+ affinity chromatography. Phytase activity and stability were determined in various pH and temperatures. The codon optimized Y. intermedia phytase gene was sub-cloned successfully.The expression was confirmed by SDS-PAGE and Western blot analysis. The recombinant enzyme (approximately 45 kDa) was purified. Specific activity of enzyme was 3849 (U.mg -1 ) with optimal pH 5 and optimal temperature of 55°C. Thermostability (80°C for 15 min) and pH stability (3-6) of the enzyme were 56 and more than 80%, respectively. The results of the expression and enzyme characterization revealed that the optimized Y. intermedia phytase gene has a good potential to be produced commercially andto be applied in animals' foodsindustry.

    Prevotella intermedia is a periodontal pathogen that requires iron for its growth. Although this organism has hemolytic activity, the precise nature of its hemolytic substances and their associated hemolytic actions are yet to be fully determined. In the present study, we identified and characterized several putative hly genes in P. intermedia ATCC25611 which appear to encode hemolysins. Six hly genes (hlyA, B, C, D, E, and hlyI) of P. intermedia were identified by comparing their nucleotide sequences to those of known hly genes of Bacteroides fragilis NCTC9343. The hlyA-E, and hlyI genes were overexpressed individually in the non-hemolytic Escherichia coli strain JW5181 and examined its contribution to the hemolytic activity on sheep blood agar plates. E. coli cells expressing the hlyA and hlyI genes exhibited hemolytic activity under anaerobic conditions. On the other hand, only E. coli cells stably expressing the hlyA gene were able to lyse the red blood cells when cultured under aerobic conditions. In addition, expression of the hlyA and hlyI genes was significantly upregulated in the presence of red blood cells. Furthermore, we found that the growth of P. intermedia was similar in an iron-limited medium supplemented with either red blood cells or heme. Taken together, our results indicate that the hlyA and hlyI genes of P. intermedia encode putative hemolysins that appear to be involved in the lysis of red blood cells, and suggest that these hemolysins might play important roles in the iron-dependent growth of this organism.

    Interleukin-6 (IL-6) is a key proinflammatory cytokine which plays a central role in the pathogenesis of periodontal disease. Host modulatory agents targeting at inhibiting IL-6, therefore, appear to be beneficial in slowing the progression of periodontal disease and potentially reducing destructive aspects of the host response. The present study was designed to investigate the effect of the macrolide antibiotic azithromycin on IL-6 generation in murine macrophages treated with lipopolysaccharide (LPS) from Prevotella intermedia, a pathogen implicated in inflammatory periodontal disease, and its mechanisms of action. Azithromycin significantly suppressed IL-6 production as well as its mRNA expression in P. intermedia LPS-activated RAW264.7 cells. LPS-induced activation of JNK and p38 was not affected by azithromycin treatment. Azithromycin failed to prevent P. intermedia LPS from degrading IκB-α. Instead, azithromycin significantly diminished nuclear translocation and DNA binding activity of NF-κB p50 subunit induced with LPS. Azithromycin inhibited P. intermedia LPS-induced STAT1 and STAT3 phosphorylation. In addition, azithromycin up-regulated the mRNA level of SOCS1 in cells treated with LPS. In conclusion, azithromycin significantly attenuated P. intermedia LPS-induced production of IL-6 in murine macrophages via inhibition of NF-κB, STAT1 and STAT3 activation, which is possibly related to the activation of SOCS1 signaling. Further in vivo studies are required to better evaluate the potential of azithromycin in the treatment of periodontal disease. Copyright © 2014 Elsevier B.V. All rights reserved.

    Many species of the genus Prevotella are pathogens that cause oral diseases. Prevotella intermedia is known to cause various oral disorders e.g. periodontal disease, periapical periodontitis and noma as well as colonize in the respiratory tract and be associated with cystic fibrosis and chronic bronchitis. It is of clinical significance to identify the main drive of its various adaptation and pathogenicity. In order to explore the intra-species genetic differences among strains of Prevotella intermedia of different niches, we isolated a strain Prevotella intermedia ZT from the infected root canal of a Chinese patient with periapical periodontitis and gained a draft genome sequence. We annotated the genome and compared it with the genomes of other taxa in the genus Prevotella. The raw data set, consisting of approximately 65X-coverage reads, was trimmed and assembled into contigs from which 2165 ORFs were predicted. The comparison of the Prevotella intermedia ZT genome sequence with the published genome sequence of Prevotella intermedia 17 and Prevotella intermedia ATCC25611 revealed that ~14% of the genes were strain-specific. The Preveotella intermedia strains share a set of conserved genes contributing to its adaptation and pathogenic and possess strain-specific genes especially those involved in adhesion and secreting bacteriocin. The Prevotella intermedia ZT shares similar gene content with other taxa of genus Prevotella. The genomes of the genus Prevotella is highly dynamic with relative conserved parts: on average, about half of the genes in one Prevotella genome were not included in another genome of the different Prevotella species. The degree of conservation varied with different pathways: the ability of amino acid biosynthesis varied greatly with species but the pathway of cell wall components biosynthesis were nearly constant. Phylogenetic tree shows that the taxa from different niches are scarcely distributed among clades. Prevotella intermedia ZT

    In addition to regulating body weight, leptin is also recognized for its role in the regulation of immune function and inflammation. The purpose of this study was to investigate the effect of leptin on Prevotella (P.) intermedia lipopolysaccharide (LPS)-induced tumor necrosis factor (TNF)-alpha production in differentiated THP-1 cells, a human monocytic cell line. LPS from P. intermedia ATCC 25611 was prepared by the standard hot phenol-water method. THP-1 cells were incubated in the medium supplemented with phorbol myristate acetate to induce differentiation into macrophage-like cells. The amount of TNF-alpha and interleukin-8 secreted into the culture medium was determined by enzyme-linked immunosorbent assay (ELISA). TNF-alpha and Ob-R mRNA expression levels were determined by semi-quantitative reverse transcription-polymerase chain reaction analysis. Leptin enhanced P. intermedia LPS-induced TNF-alpha production in a dose-dependent manner. Leptin modulated P. intermedia LPS-induced TNF-alpha expression predominantly at the transcriptional level. Effect of leptin on P. intermedia LPS-induced TNF-alpha production was not mediated by the leptin receptor. The ability of leptin to enhance P. intermedia LPS-induced TNF-alpha production may be important in the establishment of chronic lesion accompanied by osseous tissue destruction observed in inflammatory periodontal disease.

    Spinal cord compression due to extramedullary hematopoiesis is an extremely rare complication of thalassemia intermedia. No cases with this complication have been reported in the first decade of life, because masses of heterotropic marrow developed in patients as a result of continuous erythropoiesis. We report the 9-year-old patient suffering from thalassemia intermedia and presenting spinal cord compression. We also review the literature about treatment options, because there is no consensus about the optimal treatment of these patients. Our patient was successfully treated with radiation therapy followed by hydroxyurea. With this combination therapy, he had no recurrence during the 4-year follow-up period. Clinical awareness of this phenomenon with the early treatment is essential for optimizing the successful outcome.

    It has been shown that a full vector measurement of the total field allows one to uniquely distinguish the incident and reflected waves at each observation point without the use of a spatial difference based on an analysis of the polarization structure of the interference pattern which arises during reflection of electromagnetic waves from an intermedia boundary. We have investigated the stability of these procedures with respect to measurement noise by means of numerical modeling.

    Several reports have indicated that dietary intake of DHA is associated with lower prevalence of periodontitis. In the present study, we investigated the effect of DHA on the production of proinflammatory mediators in murine macrophage-like RAW264.7 cells stimulated with lipopolysaccharide (LPS) isolated from Prevotella intermedia, a pathogen implicated in inflammatory periodontal disease, and its mechanisms of action. LPS was isolated from lyophilised P. intermedia ATCC 25,611 cells using the standard hot-phenol-water protocol. Culture supernatants were collected and assayed for NO, IL-1β and IL-6. Real-time PCR analysis was carried out to detect the expression of inducible NO synthase (iNOS), IL-1β, IL-6 and haeme oxygenase-1 (HO-1) mRNA. Immunoblot analysis was carried out to quantify the expression of iNOS and HO-1 protein and concentrations of signalling proteins. DNA-binding activities of NF-κB subunits were determined using an ELISA-based assay kit. DHA significantly attenuated the production of NO, IL-1β and IL-6 at both gene transcription and translation levels in P. intermedia LPS-activated RAW264.7 cells. DHA induced the expression of HO-1 in cells treated with P. intermedia LPS. Selective inhibition of HO-1 activity by tin protoporphyrin IX significantly mitigated the inhibitory effects of DHA on LPS-induced NO production. DHA significantly attenuated the phosphorylation of c-Jun N-terminal kinase induced by LPS. In addition, DHA suppressed the transcriptional activity of NF-κB by regulating the nuclear translocation and DNA-binding activity of NF-κB p50 subunit and inhibited the phosphorylation of signal transducer and activator of transcription 1. Further in vivo studies are needed to better evaluate the potential of DHA in humans as a therapeutic agent to treat periodontal disease.

    Full Text Available Los contrastes territoriales se ha incrementado desde el inicio de los procesos de globalización e integración, pero, al mismo tiempo, las ciudades están mostrando diferente capacidad de respuesta ante esas transformaciones. Dentro de la Unión Europea, el policentrismo y el papel de las ciudades intermedias han cobrado creciente importancia en la actual agenda política, especialmente en el caso de las regiones periféricas con problemas estructurales que dificultan su desarrollo. El artículo hace una revisión crítica del paradigma de los distritos industriales y los ambientes innovadores para centrarse en su posible utilidad en la búsqueda de las claves para la construcción de ciudades intermedias innovadoras. Se concede especial importancia a los actores locales, las redes institucionales, la organización de sistemas productivos locales y la gobernabilidad territorial. Por último, se plantean algunas propuestas para apoyar la consolidación de procesos innovativos en ciudades intermedias.

    A distinct population of Anteholosticha intermedia was isolated from soil in the Great Smoky Mountains of North Carolina, USA, and its morphology, morphogenesis and molecular phylogeny investigated by microscopic observations of live and protargol-prepared specimens and analyses of the sequence of small subunit (SSU) rDNA. Our population closely resembles the populations from Austria and Korea. Members of the genus Anteholosticha have been regarded as ontogenetically diverse, which is confirmed by the present work. The most noteworthy ontogenetic feature of the American population of A. intermedia is that the oral primordium in the proter appears apokinetally at the posterior end of the undulating membranes anlage at the beginning of division and then dedifferentiates midway through morphogenesis. Molecular phylogenetic analyses demonstrate, with high support, that the American population of A. intermedia is clearly distinct from congeners and branches as part of a sister lineage to the Bakuella-Urostyla clade that belongs to the major clade comprising the order Urostylida.

    Spikes of Eltrigia intermedia were radiated with 5-100 Gy γ-ray during anthesis, and then their pollens were collected to pollinate to the common wheat 'J-11' and 'Chinese Spring'. The effects of pollen irradiation on the seed setting, embryo development, embryo culture and plantlet rate were studied. The results showed that low dose (5-9 Gy) of irradiation enhanced the seed setting for Chinese spring x E. intermedia, but no such effect for J-11xE. intermedia. Irradiation with all doses damaged embryo development, percentage of seeds with embryos; rate of immature hybrid embryos developing into plantlets decreases with the increased doses. Percentage of seeds with abnormal embryos increased significantly with the doses. 12.9%-14.5% of embryos could develop into plants in 30 Gy treatment, which seldom occur to wheat. Embryos in 50 Gy-100 Gy treatment were affected so serious that even none of them could develop into plants in vitro culture. It may be an effective approach to obtaining more mutants and enhancing induced mutation breeding by using combination of pollen irradiation, immature embryo rescue and anther culture of the resultant progenies.

    Prevotella intermedia has long been known to be as the principal etiologic agent of periodontal diseases and associated with various systemic diseases. Previous studies showed that the intra-species difference exists in capacity of biofilm formation, antibiotic resistance, and serological reaction among P. intermedia strains. Here we report the genome sequence of P. intermedia SUNY aB G8-9K-3 (designated ATCC49046) that displays a relatively high antimicrobial resistant and biofilm-forming capacity. Genome sequencing information provides important clues in understanding the genetic bases of phenotypic differences among P. intermedia strains.

El presente trabajo pretende comunicar la factibilidad y seguridad de la implantación de células madre en pacientes con degeneraciones de retina, como la retinosis pigmentaria y la degeneración macular seca relacionada con la edad, a partir de un estudio preliminar, realizado en pacientes atendidos en la consulta de oftalmología del Hospital General Docente “Dr. Ernesto Guevara de La Serna”, en la provincia de Las Tunas, Cuba. Los mismos fueron tratados con implantación de células madre adultas autólogas, procedentes de la médula ósea, y movilizadas a la sangre periférica mediante el factor estimulador de colonias de granulocitos. Se hizo aplicación local por las vías retrobulbar y peribulbar en ambos ojos, e intravitrea solo en el ojo más afectado. El resto de las células obtenidas se inyectó por vía endovenosa. Se trataron 30 pacientes en ambos ojos en el periodo de marzo a agosto del presente año. Las variables analizadas fueron: agudeza visual y complicaciones del método de implante. Se pudo comprobar que la mejoría visual en ellos fue en el ojo del triple implante, aplicación intravitrea. En ningún caso hubo reacciones adversas generales y se presentaron complicaciones locales en dos casos, debido a uveítis anterior ligera en un ojo, después del implante de células madre, con resolución a las 72 horas con colirios esteroideos.

    Byrsonima intermedia is commonly used for its antiseptic, antimicrobial, and anti-inflammatory properties in the treatment of diarrhea and dysentery in Brazilian folk medicine. The purpose of this study was to examine the anti-inflammatory activity of the aqueous extract and fractions of Byrsonima intermedia leaves. Rats with carrageenan-induced paw edema and fibrovascular tissue growth, which was induced by subcutaneous implantation of a cotton pellet, were used as acute and chronic animal models of inflammation to investigate the anti-inflammatory effects of the aqueous extract and the individual ethyl acetate (EtOAc) and aqueous fractions of Byrsonima intermedia and catechin. High-performance liquid chromatography (HPLC) was used to determine the fingerprint chromatogram of the aqueous extract and fractions of Byrsonima intermedia. The crude aqueous extract at test doses of 30-300 mg/kg p.o. clearly demonstrated anti-inflammatory effects by reducing carrageenan-induced paw edema, as did the ethyl acetate (100mg/kg) and aqueous fractions (30-100mg/kg). In the chronic inflammation rat animal model with fibrovascular tissue growth, the aqueous extract of Byrsonima intermedia (BiAE) at doses of 30-300 mg/kg and the individual EtOAc and aqueous fractions at doses of 30-100mg/kg and catechin significantly reduced the formation of granulomatous tissue. The presence of catechin and phenolic compounds in the extract and fractions of Byrsonima intermedia was confirmed using HPLC. BiAE and the individual EtOAc and aqueous fractions of Byrsonima intermedia exhibited chronic and acute anti-inflammatory efficacy in rats, which supports previous claims of its use in traditional medicine.

    Nitric oxide (NO) is a short-lived bioactive molecule that is known to play an important role in the pathogenesis of periodontal disease. In the current study, we investigated the effect of the flavonoid quercetin on the production of NO in murine macrophages activated with lipopolysaccharide (LPS) from Prevotella intermedia, a pathogen related to inflammatory periodontal disease, and tried to elucidate the underlying mechanisms of action. LPS was isolated from P. intermedia ATCC 25611 cells by the standard hot phenol-water method. The concentration of NO in cell culture supernatants was determined by measuring the accumulation of nitrite. Inducible NO synthase (iNOS) and heme oxygenase-1 (HO-1) protein expression, phosphorylation of c-Jun N-terminal kinase (JNK) and p38, inhibitory κB (IκB)-α degradation, and signal transducer and activator of transcription 1 (STAT1) phosphorylation were analyzed via immunoblotting. Quercetin significantly attenuated iNOS-derived NO production in RAW246.7 cells activated by P. intermedia LPS. In addition, quercetin induced HO-1 protein expression in cells activated with P. intermedia LPS. Tin protoporphyrin IX (SnPP), a competitive inhibitor of HO-1, abolished the inhibitory effect of quercetin on LPS-induced NO production. Quercetin did not affect the phosphorylation of JNK and p38 induced by P. intermedia LPS. The degradation of IκB-α induced by P. intermedia LPS was inhibited when the cells were treated with quercetin. Quercetin also inhibited LPS-induced STAT1 signaling. Quercetin significantly inhibits iNOS-derived NO production in murine macrophages activated by P. intermedia LPS via anti-inflammatory HO-1 induction and inhibition of the nuclear factor-κB and STAT1 signaling pathways. Our study suggests that quercetin may contribute to the modulation of host-destructive responses mediated by NO and appears to have potential as a novel therapeutic agent for treating inflammatory periodontal disease.

    During a blood meal, Lutzomyia intermedia sand flies transmit Leishmania braziliensis, a parasite causing tegumentary leishmaniasis. In experimental leishmaniasis, pre-exposure to saliva of most blood-feeding sand flies results in parasite establishment in absence of any skin damages in mice challenged with dermotropic Leishmania species together with saliva. In contrast, pre-immunization with Lu. intermedia salivary gland sonicate (SGS) results in enhanced skin inflammatory exacerbation upon co-inoculation of Lu. intermedia SGS and L. braziliensis. These data highlight potential unique features of both L. braziliensis and Lu. intermedia. In this study, we investigated the genes modulated by Lu. intermedia SGS immunization to understand their potential impact on the subsequent cutaneous immune response following inoculation of both SGS and L. braziliensis. The cellular recruitment and global gene expression profile was analyzed in mice repeatedly inoculated or not with Lu. intermedia. Microarray gene analysis revealed the upregulation of a distinct set of IFN-inducible genes, an immune signature not seen to the same extent in control animals. Of note this INF-inducible gene set was not induced in SGS pre-immunized mice subsequently co-inoculated with SGS and L. braziliensis. These data suggest the parasite prevented the upregulation of this Lu. intermedia saliva-related immune signature. The presence of these IFN-inducible genes was further analyzed in peripheral blood mononuclear cells (PBMCs) sampled from uninfected human individuals living in a L. braziliensis-endemic region of Brazil thus regularly exposed to Lu. intermedia bites. PBMCs were cultured in presence or absence of Lu. intermedia SGS. Using qRT-PCR we established that the IFN-inducible genes induced in the skin of SGS pre-immunized mice, were also upregulated by SGS in PBMCs from human individuals regularly exposed to Lu. intermedia bites, but not in PBMCs of control subjects. These data demonstrate

    The presence of certain oral pathogens at implant sites can hinder the osseointegration process. However, it is unclear how and by what microorganisms it happens. This study investigated whether the presence of oral pathogens of Porphyromonas gingivalis and Prevotella intermedia individually, play a role in the failure of bone formation by determining the expression profiles of Transforming Growth Factor Beta (TGF-β/Bone Morphogenic Protein (BMP) and Toll-Like Receptor (TLR) pathways in challenged osteoblasts. Cell viability of P. gingivalis and P. intermedia challenged osteoblasts were determined by WST assay. Changes in osteoblast morphology and inhibition of mineralization were observed by Scanning Electron Microscopy (SEM) and Von Kossa staining, respectively. Expression of TGF-β and TLR pathway genes on challenged cells were identified by RT profiler array. Both P. gingivalis and P. intermedia challenges resulted in reduced viability and mineralization of osteoblasts. Viability was reduced to 56.8% (P. gingivalis) and 52.75% (P. intermedia) at 1000 multiplicity. Amongst 48 genes examined, expressions of BMPER, SMAD1, IL8 and NFRKB were found to be highly upregulated by both bacterial challenges (Fold Change > 4). P. gingivalis and P. intermedia could play a role in implant failure by changing the expression profiles of genes related to bone formation and resorption.

    The pathogenicity of obligate and facultative anaerobic bacteria commonly found in endodontic infections was tested using a mouse model. The capacity of inducing abscesses was evaluated seven days after subcutaneous injection of the bacteria in pure culture and in combinations with either Prevotella intermedia or Prevotella nigrescens. Nine of the fifteen bacterial strains tested were pathogenic in pure culture. No statistically significant differences were detected between these strains in pure culture and in mixtures with either P. intermedia or P. nigrescens. Synergism between the bacterial strains was only apparent when associating Porphyromonas endodontalis with P. intermedia or P. nigrescens. Histopathological examination of tissue sections from induced abscesses revealed an acute inflammatory reaction, dominated by polymorphonuclear leukocytes. Sections from the control group using sterile medium showed no evidence of inflammatory reaction.

    WRKY transcription factors, one of the largest families of transcriptional regulators in plants, play important roles in plant development and various stress responses. The WRKYs of Caragana intermedia are still not well characterized, although many WRKYs have been identified in various plant species. We identified 53 CiWRKY genes from C. intermedia transcriptome data, 28 of which exhibited complete open reading frames (ORFs). These CiWRKYs were divided into three groups via phylogenetic analysis according to their WRKY domains and zinc finger motifs. Conserved domain analysis showed that the CiWRKY proteins contain a highly conserved WRKYGQK motif and two variant motifs (WRKYGKK and WKKYEEK). The subcellular localization of CiWRKY26 and CiWRKY28-1 indicated that these two proteins localized exclusively to nuclei, supporting their role as transcription factors. The expression patterns of the 28 CiWRKYs with complete ORFs were examined through quantitative real-time PCR (qRT-PCR) in various tissues and under different abiotic stresses (drought, cold, salt, high-pH and abscisic acid (ABA)). The results showed that each CiWRKY responded to at least one stress treatment. Furthermore, overexpression of CiWRKY75-1 and CiWRKY40-4 in Arabidopsis thaliana suppressed the drought stress tolerance of the plants and delayed leaf senescence, respectively. Fifty-three CiWRKY genes from the C. intermedia transcriptome were identified and divided into three groups via phylogenetic analysis. The expression patterns of the 28 CiWRKYs under different abiotic stresses suggested that each CiWRKY responded to at least one stress treatment. Overexpression of CiWRKY75-1 and CiWRKY40-4 suppressed the drought stress tolerance of Arabidopsis and delayed leaf senescence, respectively. These results provide a basis for the molecular mechanism through which CiWRKYs mediate stress tolerance.

    Excessive ineffective erythropoiesis in thalassemia intermedia may cause paravertebral pseudotumors of extramedullary hematopoiesis. Due to the proximity to the spinal canal, these paravertebral masses carry the risk of severe neurological damage. Treatment strategies include hypertransfusion, radiotherapy, and laminectomy. Hydroxyurea, stimulating fetal hemoglobin synthesis, may represent an alternative therapeutic approach. We report on a 26-year-old patient suffering from thalassemia intermedia with progressive anemia symptoms and presenting multiple intrathoracic paravertebral pseudotumors of extramedullary hematopoiesis. Hypertransfusion therapy and splenectomy were followed by regular transfusion (baseline hemoglobin 10 g/dl) and chelation with desferrioxamine. With this treatment, clinical symptoms disappeared, paravertebral hematopoietic masses did not progress, but severe hemosiderosis developed within a few years. Hydroxyurea therapy was initiated to increase the efficacy of erythropoiesis, thereby reducing the required transfusion volume but suppressing concomitantly further expansion of extramedullary hematopoiesis, and finally leading to a reduction of transfusional iron load. Treatment was started with 4 mg/kg per day and stepwise increased to 12.5 mg/kg per day. The fetal hemoglobin concentration increased from 4.5 to 5.5 g/dl after 1 year and to 9.9 g/dl after 2 years of treatment. The yearly transfusion volume was halved during the 1st year of treatment. At present, after 26 months of treatment, the patient has been transfusion-independent for 10 months. Serum ferritin levels decreased from 2844 to 1335 ng/ml. Size and shape of paravertebral hematopoietic pseudotumors remained stable. No side effects of hydroxyurea have been observed. In thalassemia intermedia patients with extramedullary hematopoiesis, hydroxyurea may lead to independence from regular transfusion therapy without further expansion of ectopic hematopoietic tissue.

    Background The yersiniae (Enterobacteriaceae) occupy a variety of niches, including some in human and flea hosts. Metabolic adaptations of the yersiniae, which contribute to their success in these specialized environments, remain largely unknown. We report results of an investigation of the transcriptome under aerobic and anaerobic conditions for Y. intermedia, a non-pathogenic member of the genus that has been used as a research surrogate for Y. pestis. Y. intermedia shares characteristics of pathogenic yersiniae, but is not known to cause disease in humans. Oxygen restriction is an important environmental stimulus experienced by many bacteria during their life-cycles and greatly influences their survival in specific environments. How oxygen availability affects physiology in the yersiniae is of importance in their life cycles but has not been extensively characterized. Methodology/Principal Findings Tiled oligonucleotide arrays based on a draft genome sequence of Y. intermedia were used in transcript profiling experiments to identify genes that change expression in response to oxygen availability during growth in minimal media with glucose. The expression of more than 400 genes, constituting about 10% of the genome, was significantly altered due to oxygen-limitation in early log phase under these conditions. Broad functional categorization indicated that, in addition to genes involved in central metabolism, genes involved in adaptation to stress and genes likely involved with host interactions were affected by oxygen-availability. Notable among these, were genes encoding functions for motility, chemotaxis and biosynthesis of cobalamin, which were up-regulated and those for iron/heme utilization, methionine metabolism and urease, which were down-regulated. Conclusions/Significance This is the first transcriptome analysis of a non-pathogenic Yersinia spp. and one of few elucidating the global response to oxygen limitation for any of the yersiniae. Thus this study

    Aortitis is a general term that refers to all conditions involving an inflammation of the aortic wall. This case report describes the surgical approach of a patient with infectious and symptomatic aortitis caused by the rare vector Prevotella intermedia. A 44-year old male patient was admitted with fever and general discomfort after a period of sore throat in a non-teaching hospital. After two weeks he developed acute abdominal and back pain accompanied by sweating and elevated infection parameters. Computed tomography angiography revealed atherosclerotic changes of the infrarenal aorta with a locally contained rupture of the aorta alongside peri-aortal signs of inflammation (and aortitis aspects). An urgent aortic reconstruction was performed according to Nevelsteen. The blood cultures turned out positive for Prevotella intermedia. Postoperatively the patient received antibiotics for six weeks. The patient recovered uneventful from this infection and surgical procedure. A complicated and acute aortitis is a rare but potentially life-threatening disease. The aetiology can be ordered into two main groups; inflammatory and infectious. Diagnosis is based upon symptoms, biochemical values, microbiological results and imaging modalities. Treatment depends on aetiology and should be discussed in an experienced multidisciplinary setting. Infectious aortitis should be treated with antibiotics for at least six weeks with close monitoring of the patient's clinic and biochemical values, even after surgery. Prevotella intermedia is a rare causative agent for aortitis. Acute aortitis is a challenging clinical entity which should be managed in an equipped medical center by an experienced multidisciplinary team. Copyright © 2017 The Authors.

    Full Text Available High-throughput sequencing has helped to reveal the close relationship between Prevotella and periodontal disease, but the roles of subspecies diversity and genomic variation within this genus in periodontal diseases still need to be investigated. We performed a comparative genome analysis of 48 Prevotella intermedia and Prevotella nigrescens isolates that from the same cohort of subjects to identify the main drivers of their pathogenicity and adaptation to different environments. The comparisons were done between two species and between disease and health based on pooled sequences. The results showed that both P. intermedia and P. nigrescens have highly dynamic genomes and can take up various exogenous factors through horizontal gene transfer. The major differences between disease-derived and health-derived samples of P. intermedia and P. nigrescens were factors related to genome modification and recombination, indicating that the Prevotella isolates from disease sites may be more capable of genomic reconstruction. We also identified genetic elements specific to each sample, and found that disease groups had more unique virulence factors related to capsule and lipopolysaccharide synthesis, secretion systems, proteinases, and toxins, suggesting that strains from disease sites may have more specific virulence, particularly for P. intermedia. The differentially represented pathways between samples from disease and health were related to energy metabolism, carbohydrate and lipid metabolism, and amino acid metabolism, consistent with data from the whole subgingival microbiome in periodontal disease and health. Disease-derived samples had gained or lost several metabolic genes compared to healthy-derived samples, which could be linked with the difference in virulence performance between diseased and healthy sample groups. Our findings suggest that P. intermedia and P. nigrescens may serve as “crucial substances” in subgingival plaque, which may

    Heart disease is the main cause of mortality and morbidity in patients with beta thalassemia, rendering its early diagnosis vital. We studied and compared echocardiographic findings in patients with beta thalassemia major, patients with beta thalassemia intermedia, and a control group. Eighty asymptomatic patients with thalassemia major and 22 asymptomatic cases with thalassemia intermedia (8-25 years old) were selected from those referred to Ali Asghar Hospital (Zahedan-Iran) between June 2008 and June 2009. Additionally, 80 healthy individuals within the same age and sex groups were used as controls. All the individuals underwent echocardiography, the data of which were analyzed with the Student t-test. The mean value of the pre-ejection period/ejection time ratio of the left ventricle during systole, the diameter of the posterior wall of the left ventricle during diastole, the left and right isovolumic relaxation times, and the right myocardial performance index in the patients with beta thalassemia major and intermedia increased significantly compared to those of the controls, but the other parameters were similar between the two patient groups. The mean values of the left and right pre-ejection periods, left ventricular end systolic dimension, and left isovolumic contraction time in the patients with thalassemia intermedia increased significantly compared to those of the controls. In the left side, myocardial performance index, left ventricular mass index, isovolumic contraction time, and deceleration time exhibited significant changes between the patients with thalassemia major and those with thalassemia intermedia, whereas all the echocardiographic parameters of the right side were similar between these two groups. The results showed that the systolic and diastolic functions of the right and left sides of the heart would be impaired in patients with thalassemia major and thalassemia intermedia. Consequently, serial echocardiography is suggested in

    Leishmania parasites are transmitted in the presence of sand fly saliva. Together with the parasite, the sand fly injects salivary components that change the environment at the feeding site. Mice immunized with Phlebotomus papatasi salivary gland (SG) homogenate are protected against Leishmania major infection, while immunity to Lutzomyia intermedia SG homogenate exacerbated experimental Leishmania braziliensis infection. In humans, antibodies to Lu. intermedia saliva are associated with risk of acquiring L. braziliensis infection. Despite these important findings, there is no information regarding the repertoire of Lu. intermedia salivary proteins. A cDNA library from the Salivary Glands (SGs) of wild-caught Lu. intermedia was constructed, sequenced, and complemented by a proteomic approach based on 1D SDS PAGE and mass/mass spectrometry to validate the transcripts present in this cDNA library. We identified the most abundant transcripts and proteins reported in other sand fly species as well as novel proteins such as neurotoxin-like proteins, peptides with ML domain, and three small peptides found so far only in this sand fly species. DNA plasmids coding for ten selected transcripts were constructed and used to immunize BALB/c mice to study their immunogenicity. Plasmid Linb-11--coding for a 4.5-kDa protein--induced a cellular immune response and conferred protection against L. braziliensis infection. This protection correlated with a decreased parasite load and an increased frequency of IFN-γ-producing cells. We identified the most abundant and novel proteins present in the SGs of Lu. intermedia, a vector of cutaneous leishmaniasis in the Americas. We also show for the first time that immunity to a single salivary protein from Lu. intermedia can protect against cutaneous leishmaniasis caused by L. braziliensis.

  14. Lutzomyia longipalpis saliva or salivary protein LJM19 protects against Leishmania braziliensis and the saliva of its vector, Lutzomyia intermedia.

    Natalia M Tavares

    Full Text Available BACKGROUND: Leishmania transmission occurs in the presence of insect saliva. Immunity to Phlebotomus papatasi or Lutzomyia longipalpis saliva or salivary components confers protection against an infection by Leishmania in the presence of the homologous saliva. However, immunization with Lutzomyia intermedia saliva did not protect mice against Leishmania braziliensis plus Lu. intermedia saliva. In the present study, we have studied whether the immunization with Lu. longipalpis saliva or a DNA plasmid coding for LJM19 salivary protein would be protective against L. braziliensis infection in the presence of Lu. intermedia saliva, the natural vector for L. braziliensis. METHODOLOGY/PRINCIPAL FINDINGS: Immunization with Lu. longipalpis saliva or with LJM19 DNA plasmid induced a Delayed-Type Hypersensitivity (DTH response against Lu. longipalpis as well as against a Lu. intermedia saliva challenge. Immunized and unimmunized control hamsters were then intradermally infected in the ears with L. braziliensis in the presence of Lu. longipalpis or Lu. intermedia saliva. Animals immunized with Lu. longipalpis saliva exhibited smaller lesion sizes as well as reduced disease burdens both at lesion site and in the draining lymph nodes. These alterations were associated with a significant decrease in the expression levels of IL-10 and TGF-β. Animals immunized with LJM19 DNA plasmid presented similar findings in protection and immune response and additionally increased IFN-γ expression. CONCLUSIONS/SIGNIFICANCE: Immunization with Lu. longipalpis saliva or with a DNA plasmid coding LJM19 salivary protein induced protection in hamsters challenged with L. braziliensis plus Lu. intermedia saliva. These findings point out an important role of immune response against saliva components, suggesting the possibility to develop a vaccine using a single component of Lu. longipalpis saliva to generate protection against different species of Leishmania, even those

    Full Text Available Beta thalassemia dominant results from mutations in the β globin chain gene resulting in the production of elongated, highly unstable beta globin chains. Several such mutations have been described and in a heterozygous state they may confer a phenotype more severe than that of β thalassemia trait and lead to a clinical syndrome of thalassemia intermedia and its associated complications such as extramedullary hemopoiesis, bone disease, endocrinopathies and iron overload even in the absence of transfusion. In this report we present a case of double heterozygocity for HbC and β thalassemia dominant leading to a series of complications that were treated successfully once the correct diagnosis was made.

    Parasites of the genus Leishmania cause a broad spectrum of diseases, collectively known as leishmaniasis, in humans worldwide. American cutaneous leishmaniasis is a neglected disease transmitted by sand fly vectors including Lutzomyia intermedia, a proven vector. The female sand fly can acquire or deliver Leishmania spp. parasites while feeding on a blood meal, which is required for nutrition, egg development and survival. The microbiota composition and abundance varies by food source, life stages and physiological conditions. The sand fly microbiota can affect parasite life-cycle in the vector. We performed a metagenomic analysis for microbiota composition and abundance in Lu. intermedia, from an endemic area in Brazil. The adult insects were collected using CDC light traps, morphologically identified, carefully sterilized, dissected under a microscope and the females separated into groups according to their physiological condition: (i) absence of blood meal (unfed = UN); (ii) presence of blood meal (blood-fed = BF); and (iii) presence of developed ovaries (gravid = GR). Then, they were processed for metagenomics with Illumina Hiseq Sequencing in order to be sequence analyzed and to obtain the taxonomic profiles of the microbiota. Bacterial metagenomic analysis revealed differences in microbiota composition based upon the distinct physiological stages of the adult insect. Sequence identification revealed two phyla (Proteobacteria and Actinobacteria), 11 families and 15 genera; 87 % of the bacteria were Gram-negative, while only one family and two genera were identified as Gram-positive. The genera Ochrobactrum, Bradyrhizobium and Pseudomonas were found across all of the groups. The metagenomic analysis revealed that the microbiota of the Lu. intermedia female sand flies are distinct under specific physiological conditions and consist of 15 bacterial genera. The Ochrobactrum, Bradyrhizobium and Pseudomonas were the common genera. Our results detailing

    The essential oil (EO) of Lavandula is dominated by monoterpenes, but can also contain small amounts of sesquiterpenes, depending on species and environmental conditions. For example, the sesquiterpene 9-epi-caryophyllene can make up to 8 % of the EO in a few species, including those commercially propagated for EO production. Here, we report the cloning and functional characterization of 9-epi-caryophyllene synthase (LiCPS) from the glandular trichomes of Lavandula x intermedia, cv. Grosso. The 1,617 bp open reading frame of LiCPS, which did not encode a transit peptide, was expressed in Escherichia coli and the recombinant protein purified by Ni-NTA agarose affinity chromatography. The ca. 60 kDa recombinant protein specifically converted farnesyl diphosphate to 9-epi-caryophyllene. LiCPS also produced a few monoterpenes when assayed with the monoterpene precursor geranyl diphosphate (GPP), but--unlike most monoterpene synthases--was not able to derive detectable amounts of any products from the cis isomer of GPP, neryl diphosphate. The LiCPS transcripts accumulated in developing L. x intermedia flowers and were highly enriched in glandular trichomes, but were not detected in leaves suggesting that the transcriptional expression of this gene is spatially and developmentally regulated.

    Several varieties of Lavandula x intermedia (lavandins) are cultivated for their essential oils (EOs) for use in cosmetic, hygiene and personal care products. These EOs are mainly constituted of monoterpenes including camphor, which contributes an off odor reducing the olfactory appeal of the oil. We have recently constructed a cDNA library from the glandular trichomes (the sites of EO synthesis) of L. x intermedia plants. Here, we describe the cloning of a borneol dehydrogenase cDNA (LiBDH) from this library. The 780 bp open reading frame of the cDNA encoded a 259 amino acid short chain alcohol dehydrogenase with a predicted molecular mass of ca. 27.5 kDa. The recombinant LiBDH was expressed in Escherichia coli, purified by Ni-NTA agarose affinity chromatography, and functionally characterized in vitro. The bacterially produced enzyme specifically converted borneol to camphor as the only product with K(m) and k(cat) values of 53 μM and 4.0 × 10(-4) s(-1), respectively. The LiBDH transcripts were specifically expressed in glandular trichomes of mature flowers indicating that like other Lavandula monoterpene synthases the expression of this gene is regulated in a tissue-specific manner. The cloning of LiBDH has far reaching implications in improving the quality of Lavandula EOs through metabolic engineering. Copyright © 2012 Elsevier Inc. All rights reserved.

    Full Text Available Despite being common in the Western Ghats-Sri Lanka biodiversity hotspot, Golden-backed frogs (Hylarana, Ranidae remain poorly studied. In this paper, we present some preliminary data on the morphology, behaviour, and habitat use of Hylarana intermedia, a member of the Hylarana aurantiaca species group. We find evidence for female biased size dimorphism, as well as potential shape differences between the sexes in this species. Additionally, we investigate the relationships between traits that may contribute to male conspicuousness (call rates, dorsal coloration, and body size in two breeding habitats, a paddy field and a trench. Our results suggest both size-dependent and environment-dependent variation in call rate and colour in this species. Specifically, we find evidence against the adoption of sneaker mating strategies by small males in H. intermedia, and instead find variation both within and between populations in traits contributing to male conspicuousness. We conclude by proposing future directions for research on this common frog species.

    Background: Extramedullary hematopoiesis (EMH) occurs in many disorders, including thalassemias and other hemoglobinopathies, and commonly presents in the spleen and liver. We present a case of spinal cord compression in a patient with beta-thalassemia intermedia, and review the literature and available treatment options. Patient and Methods: A 35-year-old black female with beta-thalassemia intermedia presented with a 3-week history of back pain and lower extremity weakness. Neurologic examination was consistent with spinal cord compression, and gadolinium enhanced magnetic resonance imaging (MRI) confirmed this diagnosis. She was given intravenous steroids and radiotherapy was begun in 200 cGy fractions to a total dose of 2000 cGy. Results: At the completion of radiotherapy the patient was ambulatory with mild residual weakness. MRI scans 16 months later showed smaller, but persistent masses, and she remains asymptomatic 5 years from her diagnosis. Conclusion: Recognition of spinal cord EMH requires prompt physical examination and MRI for accurate diagnosis. EMH can be managed with radiation, surgery, transfusions, or a combination of these therapies. Radiation in conservative doses of (750-3500 cGy) is non-invasive, avoids the surgical risks of potentially severe hemorrhage and incomplete resection, and has a high complete remission rate in the majority of patients. Relapse rates are moderate (37.5%), but retreatment provides excellent chance for second remission

    Diagnostic x-ray spectrometry, a method based on x-ray fluorescence analysis, was used for noninvasive determination of iron and zinc in two distinct skin areas, representing predominantly dermal and epidermal tissues, in 56 patients with beta-thalassemia major and intermedia. The mean iron levels in the skin of patients with beta-thalassemia major and intermedia were elevated by greater than 200% and greater than 50%, respectively, compared with control values. The zinc levels of both skin areas examined were within the normal range. The data indicate that the rate and number of blood transfusions, which correlated well with serum ferritin levels (r . 0.8), are not the only factors that determine the amount of iron deposition in the skin (r less than 0.6). Other sources of iron intake contribute to the total iron load in the tissues, particularly in patients who are not given multiple transfusions. The noninvasive quantitation of skin levels may reflect the extent of iron deposition in major parenchymal organs. Repeated DXS examinations of the skin could monitor the clearance of iron from the tissues of patients with iron overload in the course of therapy with chelating agents

    Thalassemia is a common disease which treatment is often based on splenectomy. The risks associated with total splenectomy stimulated partial splenectomy as a potentially alternative therapy. A 45 year-old female patient with long term follow-up for β thalassemia intermedia started to develop signs of hypersplenism and iron overload. A partial splenectomy was performed and was observed a marked hematologic improvement while preserving the desired splenic function. Partial splenectomy proved to provide a persistent decrease in hemolytic rate while preserving the integrity of splenic phagocytic function, presenting itself as an effective alternative to total splenectomy. After being subjected to partial splenectomy, our patient experienced a sustained control of hemolysis and showed no signs of hypersplenism or iron overload. No splenic regrowth or infectious complications were observed. The major drawbacks of partial splenectomy are the increased risk of intra- and postoperative bleeding, splenic remnant torsion and splenic regrowth. Partial splenectomy is an alternative to total splenectomy for the treatment of adult β Thalassemia intermedia patients avoiding the risks associated with total splenectomy.

    Black-pigmented anaerobic rods such as Prevotella spp. and Porphyromonas spp. are involved in the etiology and perpetuation of endodontic infections. The aim of this study was to evaluate the prevalence of these species in chronic endodontic infections by using culture and polymerase chain reaction (PCR) techniques. Samples of 100 patients with root canals displaying chronic endodontic infections were obtained by sterilized paper points. Bacterial identification was performed by using culture and PCR techniques. By culture, in 33% of the samples, P. intermedia-P. nigrescens (75.8%), P. gingivalis (27.3%), and P. endodontalis (9.1%) were identified, and by PCR 60% of the samples harbored P. nigrescens (43.3%), P. gingivalis (43.3%), P. intermedia (31.7%), and P. endodontalis (23.3%). The presence of these black-pigmented anaerobic rods alone or in association in chronic endodontic infections seems to be frequent. PCR is a very sensitive technique for detecting DNA from bacterial cells. Culturing is only able to reveal living bacteria and is less sensitive for the identification of low numbers of bacterial cells.

    Background Brachyspira spp. colonize the intestines of some mammalian and avian species and show different degrees of enteropathogenicity. Brachyspira intermedia can cause production losses in chickens and strain PWS/AT now becomes the fourth genome to be completed in the genus Brachyspira. Results 15 classes of unique and shared genes were analyzed in B. intermedia, B. murdochii, B. hyodysenteriae and B. pilosicoli. The largest number of unique genes was found in B. intermedia and B. murdochii. This indicates the presence of larger pan-genomes. In general, hypothetical protein annotations are overrepresented among the unique genes. A 3.2 kb plasmid was found in B. intermedia strain PWS/AT. The plasmid was also present in the B. murdochii strain but not in nine other Brachyspira isolates. Within the Brachyspira genomes, genes had been translocated and also frequently switched between leading and lagging strands, a process that can be followed by different AT-skews in the third positions of synonymous codons. We also found evidence that bacteriophages were being remodeled and genes incorporated into them. Conclusions The accessory gene pool shapes species-specific traits. It is also influenced by reductive genome evolution and horizontal gene transfer. Gene-transfer events can cross both species and genus boundaries and bacteriophages appear to play an important role in this process. A mechanism for horizontal gene transfer appears to be gene translocations leading to remodeling of bacteriophages in combination with broad tropism. PMID:21816042

    N-acetyl cysteine (NAC) is an antioxidant that possesses anti-inflammatory activities in tissues. In the field of dentistry, NAC was demonstrated to prevent the expression of LPS-induced inflammatory mediators in phagocytic cells and gingival fibroblasts during the inflammatory process, but the effect of NAC on oral pathogens has been rarely studied. Here, we examined the effect of NAC against planktonic and biofilm cells of Prevotella intermedia, a major oral pathogen. NAC showed antibacterial activity against the planktonic P. intermedia with MIC value of 3 mg/ml and significantly decreased biofilm formation by the bacterium even at sub MIC. NAC did not affect the antibiotic susceptibility of planktonic P. intermedia, showing indifference (fractional inhibitory concentration index of 0.5-4) results against the bacterium in combination with ampicillin, ciprofloxacin, tetracycline or metronidazole. On the other hand, viability of the pre-established bacterial biofilm exposed to the antibiotics except metronidazole was increased in the presence of NAC. Collectively, NAC may be used for prevention of the biofilm formation by P. intermedia rather than eradication of the pre-established bacterial biofilm. Further studies are required to explore antibacterial and anti-biofilm activity of NAC against mixed population of oral bacteria and its modulatory effect on antibiotics used for oral infectious diseases.

    Initiation and development of pregnancy-associated gingivitis is seemingly related to the microbial shift towards specific gram-negative anaerobes in subgingival biofilms. It is known that Prevotella intermedia sensu lato is able to use estradiol as an alternative source of growth instead of vitamin K. The aim of the present study was to investigate the impact of estradiol on the bacterial dipeptidyl peptidase IV (DPPIV) enzyme activity in vitro as a virulent factor of the Prevotella intermedia group bacteria, namely P. intermedia, Prevotella nigrescens, Prevotella pallens, and Prevotella aurantiaca. In all experiments, 2 strains of each Prevotella species were used. Bacteria were incubated with the concentrations of 0, 30, 90, and 120 nmol/L of estradiol and were allowed to build biofilms at an air-solid interface. DPPIV activities of biofilms were measured kinetically during 20 min using a fluorometric assay. The enzyme activity was later related to the amount of protein produced by the same biofilm, reflecting the biofilm mass. Estradiol significantly increased DPPIV activities of the 8 Prevotella strains in a strain- and dose-dependent manner. In conclusion, our in vitro experiments indicate that estradiol regulates the DPPIV enzyme activity of P. intermedia, P. nigrescens, P. pallens, and P. aurantiaca strains differently. Our results may, at least partly, explain the role of estradiol to elicit a virulent state which contributes to the pathogenesis of pregnancy-related gingivitis. Copyright © 2015 Elsevier Ltd.

    The aim of this study was to evaluate the antioxidant activity, screening the phytogenic chemical compounds, and to assess the alkaloids present in the E. intermedia to prove its uses in Pakistani folk medicines for the treatment of asthma and bronchitis. Antioxidant activity was analyzed by using 2,2-diphenyl-1-picryl-hydrazyl-hydrate assay. Standard methods were used for the identification of cardiac glycosides, phenolic compounds, flavonoids, anthraquinones, and alkaloids. High performance liquid chromatography (HPLC) was used for quantitative purpose of ephedrine alkaloids in E. intermedia . The quantitative separation was confirmed on Shimadzu 10AVP column (Shampack) of internal diameter (id) 3.0 mm and 50 mm in length. The extract of the solute in flow rate of 1 ml/min at the wavelength 210 nm and methanolic extract showed the antioxidant activity and powerful oxygen free radicals scavenging activities and the IC50 for the E. intermedia plant was near to the reference standard ascorbic acid. The HPLC method was useful for the quantitative purpose of ephedrine (E) and pseudoephedrine (PE) used for 45 samples of one species collected from central habitat in three districts (Ziarat, Shairani, and Kalat) of Balochistan. Results showed that average alkaloid substance in E. intermedia was as follows: PE (0.209%, 0.238%, and 0.22%) and E (0.0538%, 0.0666%, and 0.0514%).

    Full Text Available It is well known that strain and virulence diversity exist within the population structure of Porphyromonas gingivalis. In the present study we investigate intra- and inter-species variability in biofilm formation of Porphyromonas gingivalis and partners Prevotella intermedia and Prevotella nigrescens. All strains tested showed similar hydrophobicity, except for P. gingivalis W83 which has roughly half of the hydrophobicity of P. gingivalis ATCC33277. An intraspecies variability in coaggregation of P. gingivalis with P. intermedia was also found. The association P. gingivalis W83/P. intermedia 17 produced the thickest biofilm and strain 17 was prevalent. In a two-compartment system P. gingivalis W83 stimulates an increase in biomass of strain 17 and the latter did not stimulate the growth of P. gingivalis W83. In addition, P. gingivalis W83 also stimulates the growth of P. intermedia ATCC25611 although strain W83 was prevalent in the association with P. intermedia ATCC25611. P. gingivalis ATCC33277 was prevalent in both associations with P. intermedia and both strains of P. intermedia stimulate the growth of P. gingivalis ATCC33277. FISH images also showed variability in biofilm structure. Thus, the outcome of the association P. gingivalis/P. intermedia seems to be strain-dependent, and both soluble factors and physical contact are relevant. The association P. gingivalis-P. nigrescens ATCC33563 produced larger biomass than each monotypic biofilm, and P. gingivalis was favored in consortia, while no differences were found in the two-compartment system. Therefore, in consortia P. gingivalis-P. nigrescens physical contact seems to favor P. gingivalis growth. The intraspecies variability found in our study suggests strain-dependence in ability of microorganisms to recognize molecules in other bacteria which may further elucidate the dysbiosis event during periodontitis development giving additional explanation for periodontal bacteria, such as P

Partindo dessa premissa epistemológica, nosso artigo objetivou interpretar a terapia cognitiva de Aaron Beck como conhecimento construído e construtor do fenômeno de reflexividade da alta modernidade, conforme interpretada por Anthony Giddens. Nossa hipótese é que a reorientação do sistema de crenças do cliente, proposta pela terapia cognitiva, é uma forma de reconstrução reflexiva da autoidentidade, visando superar conflitos típicos da instabilidade da alta modernidade. Assinalamos aspectos na terapia cognitiva que a identificam com a reflexividade, sobretudo a ideia de que a construção da autoidentidade é uma tarefa na qual o indivíduo se engaja reflexivamente.

En dicho contexto, el trabajo se plantea como objetivo central contribuir a solucionar este problema, a partir de una propuesta metodológica para el estudio de las periferias espontáneas de las ciudades latinoamericanas de escala intermedia, desde la perspectiva del desarrollo sostenible, poniendo énfasis en la dimensión física, ambiental y climática. Para ello, la investigación se organiza en tres partes: revisión y análisis de la información existente sobre la temática y consulta a expertos, para la determinación de criterios; la determinación de acciones prioritarias; y una propuesta de estructura que sustenta un sistema de indicadores. Los resultados del trabajo proponen una batería de treinta y nueve (39 indicadores referenciales, articulados en cuatro subsistemas relacionados con: la vulnerabilidad física-ambiental y climática, el eje ambiental, el desarrollo urbano y la cohesión social. Estos constituyen la principal conclusión del trabajo, el que, se espera, será útil para comenzar a tomar las primeras decisiones frente al problema de este tipo de periferias.

    Full Text Available In a semi-arid ecosystem, water is one of the most important factors that affect vegetation dynamics, such as shrub plantation. A water use strategy, including the main water source that a plant species utilizes and water use efficiency (WUE, plays an important role in plant survival and growth. The water use strategy of a shrub is one of the key factors in the evaluation of stability and sustainability of a plantation.Caragana intermedia is a dominant shrub of sand-binding plantations on sand dunes in the Gonghe Basin in northeastern Tibet Plateau. Understanding the water use strategy of a shrub plantation can be used to evaluate its sustainability and long-term stability. We hypothesized that C. intermedia uses mainly deep soil water and its WUE increases with plantation age. Stable isotopes of hydrogen and oxygen were used to determine the main water source and leaf carbon isotope discrimination was used to estimate long-term WUE. The root system was investigated to determine the depth of the main distribution. The results showed that a 5-year-old C. intermedia plantation used soil water mainly at a depth of 0-30 cm, which was coincident with the distribution of its fine roots. However, 9- or 25-year-old C. intermedia plantations used mainly 0-50 cm soil depth water and the fine root system was distributed primarily at soil depths of 0-50 cm and 0-60 cm, respectively. These sources of soil water are recharged directly by rainfall. Moreover, the long-term WUE of adult plantations was greater than that of juvenile plantations.The C. intermedia plantation can change its water use strategy over time as an adaptation to a semi-arid environment, including increasing the depth of soil water used for root growth, and increasing long-term WUE.

    Despite the well-known effects that Quaternary climate oscillations had on shaping intraspecific diversity, their role in driving homoploid hybrid speciation is less clear. Here, we examine their importance in the putative homoploid hybrid origin and evolution of Ostryopsis intermedia, a diploid species occurring in the Qinghai-Tibet Plateau (QTP), a biodiversity hotspot. We investigated interspecific relationships between this species and its only other congeners, O. davidiana and O. nobilis, based on four sets of nuclear and chloroplast population genetic data and tested alternative speciation hypotheses. All nuclear data distinguished the three species clearly and supported a close relationship between O. intermedia and the disjunctly distributed O. davidiana. Chloroplast DNA sequence variation identified two tentative lineages, which distinguished O. intermedia from O. davidiana; however, both were present in O. nobilis. Admixture analyses of genetic polymorphisms at 20 SSR loci and sequence variation at 11 nuclear loci and approximate Bayesian computation (ABC) tests supported the hypothesis that O. intermedia originated by homoploid hybrid speciation from O. davidiana and O. nobilis. We further estimated that O. davidiana and O. nobilis diverged 6-11 Ma, while O. intermedia originated 0.5-1.2 Ma when O. davidiana is believed to have migrated southward, contacted and hybridized with O. nobilis possibly during the largest Quaternary glaciation that occurred in this region. Our findings highlight the importance of Quaternary climate change in the QTP in causing hybrid speciation in this important biodiversity hotspot. © 2014 John Wiley & Sons Ltd.

    2014-07-01

    The diversity of bacteria associated with deep-water sponge Baikalospongia intermedia was evaluated by sequence analysis of 16S rRNA genes from two sponge samples collected in Lake Baikal from depths of 550 and 1204 m. A total of 64 operational taxonomic units, belonging to nine bacterial phyla, Proteobacteria (classes Alphaproteobacteria,. Betaproteobacteria, Gammaproteobacteria, and Deltaproteobacteria), Actinobacteria, Planctomycetes, Cloroflexi, Verrucomicrobia, Acidobacteria, Chlorobi, and Nitrospirae, including candidate phylum WS5, were identified. Phylogenetic analysis showed that the examined communities contained phylotypes exhibiting homology to uncultured bacteria from different lake ecosystems, freshwater sediments, soil and geological formations. Moreover, a number of phylotypes were relative to psychrophilic, methane-oxidizing, sulfate-reducing bacteria, and to microorganisms resistant to the influence of heavy metals. It seems likely that the unusual habitation conditions of deep-water sponges contribute to the taxonomic diversity of associated bacteria and have an influence on the presence of functionally important microorganisms in bacterial communities.

    Full Text Available This study aimed to evaluate the in vitro antibacterial and antifungal activities of Lavandula x intermedia Emeric ex Loisel. ‘Budrovka’, an indigenous Croatian cultivar of lavandin. For that purpose the activity of ethanolic extracts of flowers, inflorescence stalks and leaves against thirty one strains of bacteria, yeasts, dermatophytes and moulds were studied using both the agar well diffusion and broth dilution assays. Among the investigated extracts found to be effective against a broad spectrum of microorganisms, the flower extract was considered to be the most potent one. Linalool and rosmarinic acid, as the most abundant constituents found, are very likely major contributors to the observed antimicrobial effects. The results suggest that flowers of lavandin ‘Budrovka’ could serve as a rich source of natural terpene and polyphenol antimicrobial agents.

    Full Text Available ABSTRACTLaminitis in horses is often associated with endocrine disorders, especially the pituitary pars intermedia dysfunction (PPID in older animals. Morphologic exams of the laminar tissue of the hoof were performed in two horses with suspected PPID, with no clinical signs of laminitis. Changes compatible with laminitis of endocrine origin were observed, such as rounding of the nuclei of the basal cells, thinning and stretching of the secondary epidermal laminae and tissue proliferation. PPID horses with no clinical signs of laminitis may be affected by lesions of the laminar tissue of the hoof that compromise the integrity of the dermal-epidermal junction and may develop clinical symptoms of the disease. It has been suggested that the development stage of endocrine laminitis is longer, but further studies should be conducted to confirm it.

    Caffeic acid phenethyl ester (CAPE) has numerous potentially beneficial properties, including antioxidant, immunomodulatory and anti-inflammatory activities. However, the effect of CAPE on periodontal disease has not been studied before. This study was designed to investigate the efficacy of CAPE in ameliorating the production of proinflammatory mediators in macrophages activated by lipopolysaccharide (LPS) from Prevotella intermedia, a pathogen implicated in periodontal disease. LPS from P. intermedia ATCC 25611 was isolated by using the standard hot phenol-water method. Culture supernatants were assayed for nitric oxide (NO), interleukin (IL)-1β and IL-6. We used real-time polymerase chain reaction to quantify inducible NO synthase, IL-1β, IL-6, heme oxygenase (HO)-1 and suppressors of cytokine signaling (SOCS) 1 mRNA expression. HO-1 protein expression and levels of signaling proteins were assessed by immunoblot analysis. DNA-binding activities of NF-κB subunits were analyzed by using the enzyme-linked immunosorbent assay-based kits. CAPE exerted significant inhibitory effects on P. intermedia LPS-induced production of NO, IL-1β and IL-6 as well as their mRNA expression in RAW264.7 cells. CAPE-induced HO-1 expression in cells activated with P. intermedia LPS, and selective inhibition of HO-1 activity by tin protoporphyrin IX attenuated the inhibitory effect of CAPE on LPS-induced NO production. CAPE did not interfere with IκB-α degradation induced by P. intermedia LPS. Instead, CAPE decreased nuclear translocation of NF-κB p65 and p50 subunits induced with LPS, and lessened LPS-induced p50 binding activity. Further, CAPE showed strong inhibitory effects on LPS-induced signal transducer and activator of transcription 1 and 3 phosphorylation. Besides, CAPE significantly elevated SOCS1 mRNA expression in P. intermedia LPS-stimulated cells. Modulation of host response by CAPE may represent an attractive strategy towards the treatment of periodontal disease

    The purpose of this study was to investigate the influences of NCX 2121, a nitric oxide (NO)-releasing derivative of indomethacin, upon the generation of proinflammatory mediators using murine macrophages activated by lipopolysaccharide (LPS) isolated from Prevotella intermedia, which is one of the pathogens implicated in periodontal diseases. Inducible NO synthase (iNOS)-derived NO, IL-1β and IL-6 as well as their relevant mRNA were significantly attenuated by NCX 2121 in RAW264.7 cells activated by P. intermedia LPS. NCX 2121 was much more effective than the parental compound indomethacin in reducing these proinflammatory mediators. NCX 2121 triggered induction of heme oxygenase-1 (HO-1) in cells exposed to P. intermedia LPS, and its inhibitory influence upon P. intermedia LPS-elicited NO generation was notably blocked by SnPP treatment. NCX 2121 attenuated NF-κB-dependent SEAP release induced by P. intermedia LPS. NCX 2121 did not display inhibitory action towards IκB-α degradation triggered by LPS. Instead, it significantly diminished nuclear translocation as well as DNA-binding action of NF-κB p50 subunit elicited by P. intermedia LPS. Further, NCX 2121 significantly up-regulated SOCS1 mRNA expression in cells challenged with P. intermedia LPS. In summary, NCX 2121 down-regulates P. intermedia LPS-elicited generation of NO, IL-1β and IL-6 in murine macrophages in a mechanism that involves anti-inflammatory HO-1 induction as well as decrement of NF-κB activation, which may be associated with SOCS1 expression. NCX 2121 may have potential benefits as a host immunomodulatory agent for the therapy of periodontal disease. Copyright © 2017 Elsevier Inc. All rights reserved.

    Prevotella intermedia is an important periodontal pathogen that induces various inflammatory and immune responses. In this study, we investigated the effects of P. intermedia on the plasminogen system in human periodontal ligament (hPDL) cells and explored the signaling pathways involved. Using semi-quantitative reverse transcription (RT)-PCR and quantitative real-time RT-qPCR, we demonstrated that P. intermedia challenge increased tissue-type plasminogen activator (tPA) and plasminogen activator inhibitor (PAI)-2 expression in a concentration- and time-dependent manner, but exerted no influence on urokinase-type plasminogen activator and PAI-1mRNA expression in hPDL cells. Prevotella intermedia stimulation also enhanced tPA protein secretion as confirmed by enzyme-linked immunosorbent assay. Western blot results revealed that P. intermedia treatment increased phosphorylation of extracellular signal-regulated kinase (ERK), c-Jun N-terminal kinase (JNK) and p38 kinase (p38). ERK, JNK and protein kinase C inhibitors significantly attenuated the P. intermedia-induced tPA and PAI-2 expression. Furthermore, p38 and phosphatidylinositol 3-kinase inhibitors markedly decreased PAI-2 expression, whereas they showed no or little inhibition on tPA expression. In contrast, inhibition of protein kinase A greatly enhanced the upregulatory effect of P. intermedia on tPA and PAI-2 expression. Our results suggest that P. intermedia may contribute to periodontal tissue destruction by upregulating tPA and PAI-2 expression in hPDL cells via multiple signaling pathways. © 2011 Federation of European Microbiological Societies.

    Full Text Available The recent establishment of Sphagnum farming areas has created large artificial habitats where Drosera grows under semi-natural conditions. Here we test the suitability, for pharmaceutical purposes, of two Drosera species collected from such areas. We measured the concentration of the biologically active compounds 7-methyljuglone, plumbagin and quercetin in Drosera rotundifolia and D. intermedia. All three compounds were found in pharmacologically suitable concentrations with 7-methlyjuglone characteristic for D. rotundifolia and plumbagin for D. intermedia. The concentrations required for pharmacological purposes were achieved within one year, but higher concentrations occurred in older plants and plants in flower. Concentrations did not differ between plants collected in the morning and in the afternoon. Drosera plants cultivated under semi-natural conditions are suitable as sources of raw materials for industrial pharmacological applications.

    A Croatian indigenous cultivar of lavandin, Lavandula x intermedia 'Budrovka' (Lamiaceae) was studied for the phenolic acids, flavonoids, anthocyanins, procyanidins and total tannins, as well as total polyphenols content, in the flower, inflorescence stalk and leaf ethanolic extracts. Antioxidant potentials on these plant part extracts were assessed by the DPPH free radical scavenging activity, iron chelating activity, reducing power, lipid peroxidation inhibition properties and total antioxidant capacity assays. All results were compared with those of Lavandula angustifolia, the only member of the Lavandula genus officially used in modern phytotherapy. Based on the results of our parallel study, we may suggest that Lavandula x intermedia 'Budrovka' is as potent an antioxidant as Lavandula angustifolia and the antioxidant activity of the Lavandula extracts is mainly due to the presence of rosmarinic acid. A good correlation was found between the polyphenol contents and antioxidant activities of the extracts.

    Full Text Available La terapia de remplazo enzimático (TRE, consiste en suministrarle a un paciente una proteína exógena, que en su organismo está siendo sintetizada anormalmente. La proteína puede provenir de tejidos y fluidos humanos, ser sintetizada en bacterias, células de mamífero o levaduras, a las cuales se les ha introducido el gen correspondiente. Actualmente son tratadas con TRE las enfermedades de Gaucher, Fabry y la inmunodeficiencia humana combinada. Además existen avanzados estudios en las enfermedades de Hurler, Hunter, Pompe, Niemann-Pick tipo B, Morquio A, angioderma hereditario y pénfigo vulgar. Una de las limitantes de la TRE ha sido sus altos costos, debido al relativamente pequeño número de pacientes que se tratan a nivel mundial y a que el sistema usado hasta ahora, es decir, la expresión en células de mamífero, requiere procedimientos muy costosos. La expresión en bacterias o levaduras sería mucho más barato, pero las primeras no expresan proteínas glicosiladas que constituyen el 91% del total de proteínas y la mayoría de las levaduras tienen sistemas de glicosilación, distintos a los de mamíferos.Sin embargo, Pichia pastoris y Hansenula polymorpha parecen producir proteínas muy similares a las humanas, con lo cual se evitan los problemas de rechazo por parte del organismo humano. En el Instituto de Errores Innatos del Metabolismo (IEIM de la Pontificia Universidad Javeriana se adelantan estudios conducentes a la implementación de un sistema de expresión de proteínas recombinantes en levaduras para uso clínico en enfermedades lisosomales como los síndromes de Hunter y Morquio A.

    2011-01-01

    Purpose Curcumin is known to exert numerous biological effects including anti-inflammatory activity. In this study, we investigated the effects of curcumin on the production of interleukin-6 (IL-6) by murine macrophage-like RAW 264.7 cells stimulated with lipopolysaccharide (LPS) from Prevotella intermedia, a major cause of inflammatory periodontal disease, and sought to determine the underlying mechanisms of action. Methods LPS was prepared from lyophilized P. intermedia ATCC 25611 cells by the standard hot phenol-water method. Culture supernatants were collected and assayed for IL-6. We used real-time polymerase chain reaction to detect IL-6 mRNA expression. IκB-α degradation, nuclear translocation of NF-κB subunits, and STAT1 phosphorylation were characterized via immunoblotting. DNA-binding of NF-κB was also analyzed. Results Curcumin strongly suppressed the production of IL-6 at both gene transcription and translation levels in P. intermedia LPS-activated RAW 264.7 cells. Curcumin did not inhibit the degradation of IκB-α induced by P. intermedia LPS. Curcumin blocked NF-κB signaling through the inhibition of nuclear translocation of NF-κB p50 subunit. Curcumin also attenuated DNA binding activity of p50 and p65 subunits and suppressed STAT1 phosphorylation. Conclusions Although further study is required to explore the detailed mechanism of action, curcumin may contribute to blockade of the host-destructive processes mediated by IL-6 and appears to have potential therapeutic values in the treatment of inflammatory periodontal disease.

    Bacterial resistance to the commonly used antibacterial agents is an increasing challenge in the medicine, and a major problem for the health care systems; the control of their spread is a constant challenge for the hospitals. In this study, we have investigated the antimicrobial activity of the Zinc Oxide nanoparticles against clinical sample; Yersinia intermedia bacteria. Nanoparticle susceptibility constants and death kinetic were used to evaluate the antimicrobial characteristics of the Zinc Oxide (ZnO) against the bacteria. Antimicrobial tests were performed with 10 8 cfu.mL -1 at baseline. At first, Minimum Inhibitory Concentration (MIC) of ZnO was determined and then nanoparticle suspension at one and two times of the MIC was used for death kinetic and susceptibility constant assay at 0 to 360 min treatment time. ZnO nanoparticles with size ranging from 10 to 30 nm showed the highest susceptibility reaction against Y. intermedia (Z=39.06 mL.μg -1 ). The process of Y. intermedia death in ZnO suspension was assumed to follow the first-order kinetics and the survival ratio of bacteria decreased with the increasing treatment time. An increased concentration of the nanoparticle was seen to enhance the bactericidal action of the nanoparticle. Then we performed the best ratio of the nanoparticles on semi-sensitive and resistance antibiotic for the bacteria. However, based on experimental results, synergy of ZnO nanoparticles and Oxacilin was determined and Y. intermedia showed a higher sensitivity compared to the ZnO nanoparticles alone. The results of the present study illustrates that ZnO has a strong antimicrobial effect and could potentially be employed to aid the bacterial control. It could also improve- antibacterial effects in combination with the antibiotics.

    Full Text Available Trata-se de uma revisão da literatura científica sobre a terapia nutricional no Diabetes Mellitus Gestacional, sem restrição de data e com fontes primárias indexadas nas bases de dados SciELO, PubMed, Medline. Os resultados desta revisão apontam a intervenção nutricional como uma importante aliada no controle do Diabetes Mellitus Gestacional, trazendo potenciais benefícios à saúde materno-fetal. Na avaliação do estado nutricional materno devem ser empregados os indicadores antropométricos, dietéticos, bioquímicos, clínicos e funcional. Neste sentido, a avaliação dietética deve ser detalhada, com atenção para o fracionamento e composição das refeições, e grupos de alimentos presentes. No planejamento nutricional a distribuição de macronutrientes em relação ao consumo energético diário deve ser 45-65% de carboidratos, 15-20% de proteínas e 20-35% de lipídeos. Quanto a recomendação dos edulcorantes, são liberados para gestantes acesulfame K, aspartame, neotame, sacarina e sucralose. A atividade física também deve fazer parte da estratégia de tratamento do Diabetes Mellitus Gestacional, embora o impacto do exercício nas complicações neonatais ainda mereça ser rigorosamente testado. Ademais, estudos associam a habilidade de aconselhamento nutricional com a melhorara na adesão ao cuidado nutricional. Diante desses achados, para sucesso no controle do DMG são necessários: a participação da equipe inter e multidisciplinar, o cuidado pré-natal precoce, com assistência nutricional oportuna e a garantia da assistência de qualidade ao longo da gestação.This is a scientific literature review about nutritional therapy in gestational diabetes mellitus, without date restriction and using the SciELO, PubMed and Medline databases.

    Thirty individually caged layer hens were inoculated with Brachyspira intermedia, and 20 control birds remained unchallenged. Birds received a diet containing 100 parts/10(6) zinc bacitracin (ZnB), and were monitored for 10 weeks. B. intermedia was recovered sporadically from five of the inoculated birds, and there were no significant effects on body weight, faecal water or egg production. ZnB was presumed to be indirectly inhibiting spirochaete growth, and when removed from the diet, 18 of the 30 inoculated birds rapidly became culture positive. After 4 weeks, 10 of the 30 infected birds were treated with tiamulin at 25 mg/kg for 5 days, and 10 were returned to the diet containing ZnB. Birds receiving tiamulin became spirochaete negative and maintained their egg production, but re-infection occurred. The other 20 infected birds had a significant drop in egg production, but those receiving ZnB showed a reduced colonization by B. intermedia after 3 weeks.

    The objective of this study was to identify the Fatty Acid Methyl Ester (FAME) from Neurospora intermedia N-1 that isolated from Indonesian red peanut cake (oncom). FAME profiles have been used as biochemical characters to study many different groups of organisms, such as bacteria and yeasts. FAME from N. intermedia N-1 was obtained by some stages of extraction the orange spores and fractination using a chromatotron. The pure compound (1) was characterized by 500 mHz NMR (1H and 13C), FTIR and LC-MS. Summarized data's of 1H and 13C NMR spectra of compound 1 contained 19 Carbon, 34 Hydrogen and 2 Oxygen (C19H34O2). The position of the double bonds at carbon number 8 and 12 were indicated in the HMBC spectrum (2D-NMR). LC-MS spectrum indicates molecular weight of the compound 1 as 294 which is visible by the presence of protonated molecular ion [M+H] at m/z 295. Methyl esters of long chain fatty acids was presented by a 3 band pattern of IR spectrum with bands near 1249, 1199 and 1172 cm(-1). We suggested that the structure of the pure compound 1 is methyl octadeca-8,12-dienoate. The presence methyl octadeca-8,12-dienoate in N. intermedia is the first report.

    Periodontitis is characterized by inflammation associated with the colonization of different oral pathogens. We here aimed to investigate how bacteria and host cells shape their environment in order to limit inflammation and tissue damage in the presence of the pathogen. Human dental follicle stem cells (hDFSCs) were co-cultured with gram-negative P. intermedia and T. forsythia and were quantified for adherence and internalization as well as migration and interleukin secretion. To delineate hDFSC-specific effects, gingival epithelial cells (Ca9-22) were used as controls. Direct effects of hDFSCs on neutrophils (PMN) after interaction with bacteria were analyzed via chemotactic attraction, phagocytic activity and NET formation. We show that P. intermedia and T. forsythia adhere to and internalize into hDFSCs. This infection decreased the migratory capacity of the hDFSCs by 50%, did not disturb hDFSC differentiation potential and provoked an increase in IL-6 and IL-8 secretion while leaving IL-10 levels unaltered. These environmental modulations correlated with reduced PMN chemotaxis, phagocytic activity and NET formation. Our results suggest that P. intermedia and T. forsythia infected hDFSCs maintain their stem cell functionality, reduce PMN-induced tissue and bone degradation via suppression of PMN-activity, and at the same time allow for the survival of the oral pathogens.

    Streptococcus pneumoniae is the leading cause of respiratory infection worldwide. Although oral hygiene has been considered a risk factor for developing pneumonia, the relationship between oral bacteria and pneumococcal infection is unknown. In this study, we examined the synergic effects of Prevotella intermedia, a major periodontopathic bacterium, on pneumococcal pneumonia. The synergic effects of the supernatant of P. intermedia (PiSup) on pneumococcal pneumonia were investigated in mice, and the stimulation of pneumococcal adhesion to human alveolar (A549) cells by PiSup was assessed. The effects of PiSup on platelet-activating factor receptor (PAFR) transcript levels in vitro and in vivo were analyzed by quantitative real-time PCR, and the differences between the effects of pneumococcal infection induced by various periodontopathic bacterial species were verified in mice. Mice inoculated with S. pneumoniae plus PiSup exhibited a significantly lower survival rate, higher bacterial loads in the lungs, spleen, and blood, and higher inflammatory cytokine levels in the bronchoalveolar lavage fluid (macrophage inflammatory protein 2 and tumor necrosis factor alpha) than those infected without PiSup. In A549 cells, PiSup increased pneumococcal adhesion and PAFR transcript levels. PiSup also increased lung PAFR transcript levels in mice. Similar effects were not observed in the supernatants of Porphyromonas gingivalis or Fusobacterium nucleatum. Thus, P. intermedia has the potential to induce severe bacteremic pneumococcal pneumonia with enhanced pneumococcal adhesion to lower airway cells.

    Taking a 25-year-old Caragana intermedia forest in desert steppe as test object, an investigation was conducted on the ground-dwelling arthropod community in cutting and no-cutting stands with and without reseeding, aimed to understand the effects of cutting, reseeding and their interaction on the individual number and group richness of ground-dwelling arthropod in C. intermedia forest. There were significantly lower number and richness of ground-dwelling arthropod in the open spaces than under the shrubs in the no-cutting and no-reseeding stands. Cutting, reseeding and both of them could significantly increase the number and richness of ground-dwelling arthropod in the open spaces, but not under the shrubs, compared with no cutting or reseeding. Consequently, there were no significant differences in the distribution of ground-dwelling arthropod in the open spaces and under the shrubs in the cutting, reseeding, or cutting and reseeding stands. Further, there was a similar buffer effect between cutting and reseeding on the ground-dwelling arthropod. No significant differences were observed in the ground-dwelling arthropod distribution, between cutting stand and reseeding stand, between cutting stand and cutting and reseeding stand, and between reseeding stand and cutting and reseeding stand. It was suggested that cutting, reseeding, or both of them could significantly improve the ground-dwelling arthropod diversity especially in the open spaces, being beneficial for the restoration of degraded grassland ecosystem and the rational management on artificial C. intermedia forest in desert steppe.

Foi objetivo deste estudo analisar a utilização de equipamentos de proteção individual (EPIs pelos trabalhadores de enfermagem nas unidades de terapia intensiva de um hospital de emergência localizado no município de Fortaleza/CE, Brasil. Trata-se de um estudo exploratório, descritivo e transversal, realizado nas quatro unidades da referida instituição. A coleta de dados ocorreu nos meses de setembro e outubro de 2008, através de entrevista e observação, respeitando-se os aspetos ético-legais. Participaram do estudo 45 trabalhadores da equipe de enfermagem da UTI, nas categorias de técnico e auxiliar. Os resultados revelam que os técnicos e auxiliares de enfermagem têm consciência da importância do uso de EPIs, porém não os utilizam com a devida frequência na prática de seu cotidiano laboral, devido a problemas de ordem comportamental e de logística. Os resultados deste estudo oferecem bases para uma reflexão quanto à importância da identificação de facilidades e dificuldades encontradas pela equipe na utilização dos EPIs.Apesar de los grandes avances en la prevención de infecciones hospitalarias, la adhesión a los equipamientos de protección individual sigue siendo un importante desafío entre los trabajadores de la salud.

    Full Text Available L’articolo spiega come e perché, l’utilizzo delle foto personali e quelle di famiglia delle persone in terapia durante il loro trattamento (“Tecniche di FotoTerapia” possa aumentare e approfondire tale processo, e migliorare la qualità dei risultati terapeutici. Si descrive come le foto creino un ponte in grado di raggiungere aree profonde del vissuto del cliente dove le parole non possono arrivare – fornendo quindi un eccellente mezzo per esaminare ed esplorare i sentimenti con il minimo dell’interferenza e delle difese cognitive. Basato sul principio che le fotografie presentano accanto ai dettagli visivi un contenuto emotivo, questo articolo mostra come il terapeuta formato nelle Tecniche di FotoTerapia possa usare le foto personali e quelle di famiglia del cliente per evocare ricordi, richiamare sentimenti, riconnettere pensieri, nascondere segreti, e portare alla luce il passato con nuove modalità. Si mostra come le Tecniche di FotoTerapia siano basate sul fatto che tutte le fotografie parlano il linguaggio metaforico e simbolico dell’inconscio, senza usare le parole, e quindi ogni immagine fotografica è in grado, indipendentemente dalla modalità preferita dal terapeuta, di raggiungere informazioni e sentimenti precedentemente bloccati o fortemente difesi. Dopo l’” Introduzione” e le Sezioni relative alle “Arti (e Arte Terapia” e “Fotografie (e Fotografia” che propongono le basi teoriche delle tecniche di FotoTerapia, l’articolo procede da una rassegna generale dell’“Uso delle Fotografie nella Pratica Terapeutica” a una spiegazione più dettagliata della “Cornice di Lavoro delle Tecniche di FotoTerapia”, discutendo i principi e le specifiche applicazioni di ogni tecnica, da usare singolarmente o in combinazione con le altre. È inoltre inclusa una comparazione tra le tecniche di “FotoTerapia” e le analoghe applicazioni sia della “Foto Arte Terapia” che della “Fotografia Terapeutica

  15. Identification of Stria Medullaris Fibers in the Massa Intermedia Using Diffusion Tensor Imaging.

    Kochanski, Ryan B; Dawe, Robert; Kocak, Mehmet; Sani, Sepehr

    2018-04-01

    The massa intermedia (MI) or interthalamic adhesion is an inconsistent band spanning between bilateral medial thalami that is absent in up to 20%-30% of individuals. Little is known of its significance, especially in regard to functional pathways. Probabilistic diffusion tensor imaging (DTI) has recently been used to seed the lateral habenula and define its afferent white matter pathway, the stria medullaris thalami (SM). We sought to determine whether the MI serves as a conduit for crossing of limbic fibers such as the SM. Probabilistic DTI was performed on 10 subjects who had presence of a MI as visualized on magnetic resonance imaging. Tractography was also performed on 2 subjects without MI. Manual identification of the lateral habenula on axial T1-weighted magnetic resonance imaging was used for the initial seed region for tractography. In all subjects, the SM was reliably visualized. In 7 of the 10 subjects with MI, there was evidence of SM fibers that crossed to the ipsilateral hemisphere. Three subjects with small diameter MI did not have tractographic evidence of crossing SM fibers. Of the 7 subjects with crossing SM fibers within the MI, 5 showed predilection toward the right orbitofrontal cortex from both the left and right seed regions. Probabilistic DTI provides evidence of SM fibers within the MI. Given its anatomic location as a bridging pathway between thalami, further studies are necessary to assess its role within the limbic functional network. Copyright © 2018 Elsevier Inc.

    Full Text Available Papilomatose respiratória recorrente ou papilomatose laríngea recorrente é uma doença da laringe, causada pelo papiloma vírus humano, caracterizada por lesões epiteliais verrucosas e, geralmente, recorrentes. Na literatura são descritos diversos tipos de tratamento, como cirurgia a frio, a laser e/ou uso de microdebridador, além das terapias adjuvantes; todas no sentindo de diminuir possíveis sequelas permanentes da doença. OBJETIVO: Realizar uma revisão de literatura a respeito desta doença com ênfase nas técnicas cirúrgicas e terapias adjuvantes mais utilizadas atualmente. MÉTODO: Utilizou-se a metodologia de revisão bibliográfica, por meio de levantamentos em base de dados eletrônicos de domínio público, entre 1992-2012, utilizando-se as palavras-chave: papiloma, infecções por papillomavírus, laringe, terapêutica, vacinas contra papillomavírus. RESULTADOS: Foram levantados 357 artigos, dos quais 49 foram usados como base para esta revisão. Os trabalhos científicos apontam para a redução de recidiva na maioria das terapêuticas adjuvantes. Entretanto, o levantamento demonstrou metodologias e amostras diferentes, o que não permitiu comparar os tipos de tratamento e de terapias adjuvantes. CONCLUSÃO: A escolha da técnica cirúrgica varia entre os autores, porém, há uma tendência atual ao uso do microdebridador. As terapias adjuvantes recentes, como cidofovir, vacina tetravalente contra o papiloma vírus humano e bevacizumab, necessitam de estudos mais amplos.

    Alpinia intermedia, a perennial plant that belongs to the Zingiberaceae family, has been used in folk medicine for a long time in the southern region of Japan. Because skin care is an effective approach that enables patients to manage their atopic dermatitis (AD), various herbal ingredients with few adverse effects have been evaluated for use in AD patients in recent years. In this study, we examined whether distilled extracts obtained from A. intermedia were beneficial for AD-like skin conditions in NC/Tnd mice. Topical application with the A. intermedia extracts significantly reduced the severity of AD, transepidermal water loss and scratching behavior in the mice. Supplementation of the extracts to cell cultures suppressed the expression of Tslp mRNA in PAM212 keratinocytes, degranulation in bone marrow-derived cultured mast cells (BMCMC), and neurite outgrowth in PC12 cells and dorsal root ganglia. In addition, the component analysis revealed that β-pinene was a major constituent of the A. intermedia extracts. The inhibitory effects of β-pinene both in vivo and in vitro were also demonstrated. These results indicate that topical application with the A. intermedia extract to the skin of NC/Tnd mice improved the condition of the skin by suppressing multiple inflammatory responses. The extracts may become novel skin-care remedies for AD patients. © 2017 The Authors.

  3. Acquisition of complement inhibitor serine protease factor I and its cofactors C4b-binding protein and factor H by Prevotella intermedia.

    2012-01-01

    Infection with the Gram-negative pathogen Prevotella intermedia gives rise to periodontitis and a growing number of studies implies an association of P. intermedia with rheumatoid arthritis. The serine protease Factor I (FI) is the central inhibitor of complement degrading complement components C3b and C4b in the presence of cofactors such as C4b-binding protein (C4BP) and Factor H (FH). Yet, the significance of complement inhibitor acquisition in P. intermedia infection and FI binding by Gram-negative pathogens has not been addressed. Here we show that P. intermedia isolates bound purified FI as well as FI directly from heat-inactivated human serum. FI bound to bacteria retained its serine protease activity as shown in degradation experiments with (125)I-labeled C4b. Since FI requires cofactors for its activity we also investigated the binding of purified cofactors C4BP and FH and found acquisition of both proteins, which retained their activity in FI mediated degradation of C3b and C4b. We propose that FI binding by P. intermedia represents a new mechanism contributing to complement evasion by a Gram-negative bacterial pathogen associated with chronic diseases.

    Full Text Available Existen pocos modelos animales de degeneración cognitiva que podrían ser considerados tan importantes como el modelo de lesión colinérgica de la enfermedad de Alzheimer. La enfermedad de Alzheimer es una patología neurodegenerativa asociada con el envejecimiento y con degeneración cognitiva acentuada y progresiva. Sus complejas y múltiples vías neurales secuenciales pueden conducir a la comprensión de que las intervenciones de agente único pueden ser insuficiente para impactar el curso de esta enfermedad. El tratamiento farmacológico actual es paliativo y, aunque pueda retardar el progreso de la enfermedad, no es capaz de ofrecer una cura. La combinación de drogas y sustancias antioxidantes han sido investigadas, sin embargo, existen pocos estudios que demuestran resultados consistentes basados en esta presunción. Así, el objetivo de este artículo fue destacar las terapias basadas en la reposición celular como potencial tratamiento para enfermedades del sistema nervioso periférico y central.

    Full Text Available Numerosos estudios han corroborado que la regulación de los eventos privados focalizada en la evitación experiencial juega un papel fundamental, tanto en el desarrollo de las adicciones como en su mantenimiento, llegando a producir el patrón destructivo que caracteriza a las personas ancladas en el consumo desajustado de sustancias. Las contingencias a la base del comportamiento adictivo constituyen el Trastorno de Evitación Experiencial (TEE que implica una estrategia inflexible, formada por un conjunto de acciones dirigidas al escape y la evitación de malestar, y sustentada por la coherencia ¿establecida socialmente- que supone la necesidad de regular el malestar de modo inmediato. La Terapia de Aceptación y Compromiso (ACT está diseñada para el abordaje de la Evitación Experiencial Destructiva (el TEE. En el contexto del comportamiento adictivo, la ACT ha mostrado ser eficaz en el desarrollo de una vida consistente con los valores personales cuyo coste principal supone afrontar el malestar que se deriva de la abstinencia y otras sensaciones, pensamientos y recuerdos que pudieran ser dolorosos. El presente artículo tiene como objetivo la exposición ejemplificada de los componentes fundamentales de ACT en el caso de personas con problemas de adicciones a diferentes sustancias.

    Full Text Available Con el presente trabajo pretendo mostrar que la reflexión sobre la historia de Nietzsche, expuesta en la segunda consideración intempestiva, puede ser situada en la estela de la filosofía de la historia kantiana, pues tanto Kant como Nietzsche observan efectos dañinos causados por el estudio de la historia, y proponen terapias contra ellos basadas en una concepción de un tiempo que se encuentra fuera del tiempo serial. Sin embargo muestro a su vez el punto de inflexión en donde ya no es posible concebir a Nietzsche siguiendo los pasos de Kant y establezco que Nietzsche introduce una concepción orgánica en el núcleo de sus reflexiones sobre la historia. My aim with this paper is to show the possibility of understanding Nietzsche’s consideration about history, developed in his Second Untimely Meditation, as following the path of Kantian philosophy of history. Both Kant and Nietzsche are aware of the damaging consequences produced by the study of history, therefore both suggest a therapy against them, based on a conception of time which is beyond serial time. Nevertheless, I show as well the inflection point where the possibility of conceiving Nietzsche as a Kantian is no more possible and I establish that at the core of Nietzsche´s conception of history lies an organic conception of it.

    We present CCD photometry in the Washington system C and T1 bands of 14 star clusters of the Small Magellanic Cloud (SMC). We determine ages and metallicities using theoretical isochrones, the T1 parameter and the Red Giant Standard method. Excepting IC 1708, all the observed clusters are aged between 1 and 6.3 Gyr, while their metallicities ([Fe/H]) range be- tween -0.7 and -1.4. Two important cluster formation episodes in the SMC, dated at 2 Gyr and 5 Gyr ago, were detected. During approximately the first 4 Gyr in the SMC lifetime, the cluster formation rate turned out to be constant. A detailed version of this work can be seen in Piatti et al. (2011, MNRAS, 417, 1559).

    The severity of β-thalassaemia (β-thal) intermedia is mainly correlated to the degree of imbalanced α/non α-globin chain synthesis. The phenotypic diversity of β-thal depends on this imbalance and reflects all possible combinations of α- and β-globin genotypes, levels of fetal haemoglobin (HbF) and co-inheritance of other modulating factors. This study aimed to demonstrate the validity of a new surrogate of α/non α-globin biosynthetic ratio by measuring the soluble α-Hb pool in lysed red blood cells. Our results confirm that the α-Hb pool measurement allows a good discrimination between β-thal intermedia patients, controls and α-thal patients (P intermedia patients and may be clinically useful for monitoring the evolution of the disequilibrium of globin synthesis in response to treatments. © 2017 John Wiley & Sons Ltd.

    β-Thalassemia intermedia (β-TI) is a clinical term describing a range of clinical phenotypes that are intermediate in severity between the carrier state and β-thalassemia major (β-TM). To characterize the molecular basis of β-TI in Erbil Province, Northern Iraq, 83 unrelated patients were investigated. Detection of β-globin gene mutations was carried out by reverse hybridization assay and direct gene sequencing. All patients were screened for the XmnI polymorphism by direct sequencing of HBG2 ((G)γ promoter gene). Detection of α-globin gene deletions and triplication was carried out using the reverse hybridization assay. Four main molecular patterns were identified in association with the β-TI phenotype, namely: β(+)/β(+) (38.5%), β(+)/β(0) (21.6%), β(0)/β(0) (31.3%), and β(0)/wild type (8.4%). IVS-I-6 (T > C) was the most frequently encountered mutation (55 alleles, 34.6%), followed by IVS-II-1 (G > A) and codon 8 (-AA); furthermore, we report for the first time from Iraq two β(+) mutations, -87 (C > G) and 5' untranslated region (5'UTR) +22 (G > A). The XmnI polymorphism was detected in 47.0% of patients, mainly in association with the β(0)/β(0) genotype. The α-globin gene deletions were encountered in four cases, including one case with (- -(FIL)) double gene deletion, a report that is the first from our country. The α-globin gene triplication was detected in five of the seven heterozygous β-thalassemia (β-thal) patients. Similar to other Mediterranean countries, inheritance of mild β-globin mutations was the main molecular pattern underlying β-TI in our patients followed by the ameliorating effect of the XmnI polymorphism.

    Full Text Available Patients with severe inherited β-globin chain disorders may have milder illness if they produce high levels of fetal hemoglobin (HbF. Hydroxyurea (HU has been shown to enhance HbF levels in patients with sickle cell disease and may be useful in β-thalassemias. We administered HU to 13 patients with β-thalassemia intermedia or major, including 6 splenectomized patients. The patients received escalating doses (10 to 25 mg/kg/d of HU for around 2 years (median: 21 months, range: 8 - 55 months. Eleven patients responded with an increase in the pre-transfusion HbF levels, from a base line median of 8.0% (2.5 - 61.3% to 28.0% (6.6 - 49.2% and 40.7% (4.8 - 72.3% at 3 months and 18 months post-HU, respectively. A concomitant increment in median hemoglobin levels was noted at 1, 3 and 18 months of HU therapy. Six of 7 transfusion-dependent patients who had an increment of HbF (one with β-thalassemia major also had reduced transfusion requirement over the 2-year period of HU therapy. Response to HU was also shown by a reduction in spleen size. Apart from oral ulcers that resolved upon dose reduction of HU, no significant toxicity was noted. We conclude that increased HbF production in β-thalassemia patients, with an improvement in erythropoiesis, can be achieved using HU with minimal toxicity.

    Loxoscelism is the designation given to clinical symptoms evoked by Loxosceles spider's bites. Clinical manifestations include skin necrosis with gravitational spreading and systemic disturbs. The venom contains several enzymatic toxins. Herein, we describe the cloning, expression, refolding and biological evaluation of a novel brown spider protein characterized as a hyaluronidase. Employing a venom gland cDNA library, we cloned a hyaluronidase (1200 bp cDNA) that encodes for a signal peptide and a mature protein. Amino acid alignment revealed a structural relationship with members of hyaluronidase family, such as scorpion and snake species. Recombinant hyaluronidase was expressed as N-terminal His-tag fusion protein (∼45 kDa) in inclusion bodies and activity was achieved using refolding. Immunoblot analysis showed that antibodies that recognize the recombinant protein cross-reacted with hyaluronidase from whole venom as well as an anti-venom serum reacted with recombinant protein. Recombinant hyaluronidase was able to degrade purified hyaluronic acid (HA) and chondroitin sulfate (CS), while dermatan sulfate (DS) and heparan sulfate (HS) were not affected. Zymograph experiments resulted in ∼45 kDa lytic zones in hyaluronic acid (HA) and chondroitin sulfate (CS) substrates. Through in vivo experiments of dermonecrosis using rabbit skin, the recombinant hyaluronidase was shown to increase the dermonecrotic effect produced by recombinant dermonecrotic toxin from L. intermedia venom (LiRecDT1). These data support the hypothesis that hyaluronidase is a “spreading factor”. Recombinant hyaluronidase provides a useful tool for biotechnological ends. We propose the name Dietrich's Hyaluronidase for this enzyme, in honor of Professor Carl Peter von Dietrich, who dedicated his life to studying proteoglycans and glycosaminoglycans. PMID:23658852

    he aim of this study was to investigate the presence of four black-pigmented bacteria, Porphyromonas gingivalis, Porphyromonas endodontalis, Prevotella intermedia and Prevotella nigrescens, in endodontic infections by culture and polymerase chain reaction (PCR) analyses. Microbial samples were obtained from 50 teeth with untreated necrotic pulps (primary infection) and from 50 teeth with failing endodontic treatment (secondary infection). Microbiological strict anaerobic techniques were used for serial dilution, plating, incubation, and identification. For PCR detection, the samples were analyzed using species-specific primers of 16S rDNA and the downstream intergenic spacer region. Culture and PCR detected the test species in 13/100 and 50/100 of the study teeth, respectively. The organisms were cultured from 11/50 (22%) of primarily infected root canal samples and from 2/50 (4%) of secondary root canal samples. PCR detection identified the target species in 32/50 (64%) and 18/50 (36%) of primary and secondary infections, respectively. P. gingivalis was rarely isolated by culture methods (1%), but was the most frequently identified test species by PCR (38%). Similarly, P. endodontalis was not recovered by culture from any tooth studied, but was detected by PCR in 25% of the sampled teeth. PCR-based identification also showed higher detection rates of P. intermedia (33%) and P. nigrescens (22%) than culture (13%). In conclusion, P. gingivalis, P. endodontalis, P. intermedia, and P. nigrescens were identified more frequently in teeth with necrotic pulp than in teeth with failing endodontic treatment. Also, a higher frequency of black-pigmented species was detected by PCR than by culture.

    Conclusions: Improvement in α:non-α ratio and consequent decrease of free α-globin chain might be the cause of beneficial effects of hydroxyurea therapy. Two patients who felt better didn't show significant increase in their fetal hemoglobin level, and this is in contradiction with the hypothesis claiming that the HbF level increase is the cause of such therapeutic effect. In spite of the unclear mechanism of action of this drug, hydroxyurea therapy had noticeable impacts on thalassemia intermedia and also sickle cell disease and even patients suffering from thalassemia major.

    Full Text Available Several side effects have been strongly associated with antiretroviral therapy in HIV patients. Among them, the lipodystrophy syndrome which presents alterations in body shape with central adipose hypertrophy and peripheral lipoatrophy, reported by patients as a visible marker identifying them as HIV patients. This manuscript presents an analysis of current literature regarding the psychosocial aspects of HIV patients with lipodystrophy associated with antiretroviral therapy. The results show that the alterations in body shape can be disturbing in terms of psychosocial well being, affecting quality of life and increasing the stigma associated with the disease, with consequent disturbances in social relations. This analysis provides a preliminary review of the psychosocial aspects of lipodystrophy and further studies are needed for a better understanding of this complex syndrome, which could provide new information to be used in nursing care for HIV patients affected by this problem.Varios efectos secundarios han sido fuertemente asociados con la terapia antiretroviral en pacientes con HIV.

En este manuscrito, presentamos un análisis de literatura actual con respecto a los aspectos psicosociales de pacientes con VIH presentándose con lipodistrofia asociado con la terapia antiretroviral. Los resultados demuestran que las alteraciones de la forma del cuerpo pueden ser inquietantes en lo que se refiere al bienestar psicosocial, afectando la calidad de vida y aumentando el estigma asociado con la enfermedad, con las consiguientes dificultades en las relaciones sociales.

    Full Text Available Abstract Background The presence of β-lactamases in Y. enterocolitica has been reported to vary with serovars, biovars and geographical origin of the isolates. An understanding of the β-lactamases in other related species is important for an overall perception of antibiotic resistance in yersiniae. The objective of this work was to study the characteristics of β-lactamases and their genes in strains of Y. intermedia and Y. frederiksenii, isolated from clinical and non-clinical sources in India. Results The enzymes, Bla-A (a constitutive class A penicillinase and Bla-B (an inducible class C cephalosporinase were found to be present in all the clinical and non-clinical strains of Y. intermedia and Y. frederiksenii by double disc diffusion method. The results showed differential expression of Bla-A as indicated by presence/absence of synergy whereas expression of Bla-B was quite consistent. The presence of these enzymes was also reflected in the high minimum inhibitory concentrations, MIC50 (126–1024 mg/L and MIC90 (256–1024 mg/L of β-lactam antibiotics against these species. Restriction fragment length polymorphism (RFLP revealed heterogeneity in both blaA and blaB genes of Y. intermedia and Y. frederiksenii. The blaA gene of Y. intermedia shared significant sequence identity (87–96% with blaA of Y. enterocolitica biovars 1A, 1B and 4. The sequence identity of blaA of Y. frederiksenii with these biovars was 77–79%. The sequence identity of blaB gene of Y. intermedia and Y. frederiksenii was more (85% with that of Y. enterocolitica biovars 1A, 1B and 2 compared to other species viz., Y. bercovieri, Y. aldovae and Y. ruckeri. Isoelectric focusing data further revealed that both Y. intermedia and Y. frederiksenii produced Bla-A (pI 8.7 and "Bla-B like" (pI 5.5–7.1 enzymes. Conclusion Both Y. intermedia and Y. frederiksenii showed presence of blaA and blaB genes and unequivocal expression of the two β-lactamases. Limited heterogeneity

    Phytochemical analysis of Forsythia intermedia tissues has demonstrated the presence of lignins of the dibenzylbutyrolactone and dioxabicyclo(3,3,0)octane classes, together with their O-glucosides. Lignin distribution in different parts of the part, and variation with the season has been recorded. Cell suspension cultures from F. intermedia were developed. These also synthesized lignins, though not the full range as found in the fresh tissues. Culture lines synthesizing either matairesinol 4{prime}-O-glucoside and major lignin components were established. These cultures rapidly metabolized exogenous lignins without producing detectable lignin transformation products. The seasonal variation in aryltetralin lactone levels in young plants Podophyllum hexandrum and P. peltatum has been investigated. Cell cultures of the plants were established, but no lignins were detectable in them. However, a protocol for micropropagation via embryoid production was obtained. Feeding experiments in P. hexandrum plants showed that matairesinol was a precursor of both podophyllotoxin and 4{prime}-demethylpodophyllotoxin, thus indicating it to be a common precursor of the trimethoxy and hydroxydimethoxy series of lignins in this plant. Precursor feeding experiments with {sup 3}H/{sup 14}C-labeled coniferyl alcohol showed an unexpected increase in {sup 3}H/{sup 14}C ratio when incorporated into both Forsythia and Podophyllum lignins.

    Full Text Available BACKGROUND: Although periodontitis is a risk factor for cardiovascular disease (CVD, the influence of periodontitis on Marfan syndrome (MFS with CVD is unclear. The aim of this study was to assess the relationship between periodontal bacterial burden and MSF with CVD. METHODS AND RESULTS: The subjects were patients with MFS with CVD (n = 47; age and gender matched non-MFS CVD patients (n = 48 were employed as controls. Full-mouth clinical measurements, including number of teeth, probing of pocket depth (PD, bleeding on probing (BOP and community periodontal index (CPI were recorded. We also evaluated the existence of three periodontal pathogens, Porphyromonas gingivalis, Aggregatibacter actinomycetemcomitans, and Prevotella intermedia using polymerase chain reaction assays. Serum antibody titers against the pathogens were also measured. We revealed that MFS with CVD patients had periodontitis more frequently than the age and gender matched non-MFS CVD control subjects. MFS with CVD patients had significantly severer periodontitis, fewer remaining teeth and deeper PD compared to the non-MFS CVD controls. Furthermore, the serum antibody titer level against Prevotella intermedia was significantly lower in MFS plus CVD patients compared to the non-MFS CVD patients. CONCLUSION: Periodontitis may influence the pathophysiology of cardiovascular complications in MFS patients. A specific periodontal pathogen might be a crucial therapeutic target to prevent CVD development.

    The use of extended criteria donors who might have previously been deemed unsuitable is an option to increase the organ supply for transplantation. This report presents a pediatric case of a successful liver transplantation from a donor with β-thalassemia intermedia. A patient, 6-year-old female, with a diagnosis of cryptogenic liver cirrhosis underwent deceased donor liver transplantation from a thalassemic donor. Extreme hyperferritinemia was detected shortly after transplantation. The most probable cause of hyperferritinemia was iron overload secondary to transplantation of a hemosiderotic liver. Hepatocellular injury due to acute graft rejection might have contributed to elevated ferritin levels by causing release of stored iron from the hemosiderotic liver graft. Iron chelation and phlebotomy therapies were started simultaneously in the early postoperative period to avoid iron-related organ toxicity and transplant failure. Follow-up with monthly phlebotomies after discharge yielded a favorable outcome with normal transplant functions. Thalassemia intermedia patients can be candidates of liver donors to decrease pretransplant waitlist mortality. After transplantation of a hemosiderotic liver, it is important to monitor the recipient in terms of iron overload and toxicity. Early attempts to lower iron burden including chelation therapy and/or phlebotomy should be considered to avoid organ toxicity and transplant failure. © 2017 John Wiley & Sons A/S.

    The quantification of fluorescence in dental plaque is currently being developed as a diagnostic tool to help inform and improve oral health. The oral anaerobe Prevotella intermedia exhibits red fluorescence due to the accumulation of porphyrins. pH affects the fluorescence of abiotic preparations of porphyrins caused by changes in speciation between monomers, higher aggregates and dimers, but this phenomenon has not been demonstrated in bacteria. Fluorescence spectra were obtained from suspensions of P. intermedia that were adjusted to pHs commensurate with the range found within dental plaque. Two fluorescent motifs were identified; 410 nm excitation / 634 nm emission (peak A) and 398 nm excitation / 622 nm emission (peak B). A transition in the fluorescence spectra was observed from peak A to peak B with increasing pH which was also evident as culture age increased from 24 hours to 96 hours. In addition to these 'blue-shifts', the intensity of peak A increased with pH whilst decreasing with culture age from 24 to 96 hours. A bacterium's relationship with the local physiochemical environment at the time of image capture may therefore affect the quantification of dental plaque fluorescence.

    Wild-type and H12A-mutant class II phospholipase D from L. intermedia venom were crystallized; the crystals diffracted to maximum resolutions of 1.95 and 1.60 Å, respectively. Phospholipases D are the major dermonecrotic component of Loxosceles venom and catalyze the hydrolysis of phospholipids, resulting in the formation of lipid mediators such as ceramide-1-phosphate and lysophosphatidic acid which can induce pathological and biological responses. Phospholipases D can be classified into two classes depending on their catalytic efficiency and the presence of an additional disulfide bridge. In this work, both wild-type and H12A-mutant forms of the class II phospholipase D from L. intermedia venom were crystallized.

    Full Text Available The interaction between Leishmania and sand flies has been demonstrated in many Old and New World species. Besides the morphological differentiation from procyclic to infective metacyclic promastigotes, the parasite undergoes biochemical transformations in its major surface lipophosphoglycan (LPG. An upregulation of β-glucose residues was previously shown in the LPG repeat units from procyclic to metacyclic phase in Leishmania (Viannia braziliensis, which has not been reported in any Leishmania species. LPG has been implicated as an adhesion molecule that mediates the interaction with the midgut epithelium of the sand fly in the Subgenus Leishmania. These adaptations were explored for the first time in a species from the Subgenus Viannia, L. (V. braziliensis with its natural vectors Lutzomyia (Nyssomyia intermedia and Lutzomyia (Nyssomyia whitmani. Using two in vitro binding techniques, phosphoglycans (PGs derived from procyclic and metacyclic parasites were able to bind to the insect midgut and inhibit L. braziliensis attachment. Interestingly, L. braziliensis procyclic parasite attachment was ∼11-fold greater in the midgut of L. whitmani than in L. intermedia. The epidemiological relevance of L. whitmani as a vector of American Cutaneous Leishmaniasis (ACL in Brazil is discussed.

    To assess the prevalence of three black-pigmented bacterial species (Porphyromonas endodontalis, Porphyromonas gingivalis and Prevotella intermedia) using microarray technology in root canals of teeth associated with primary endodontic infections in a Chinese population. Microbial samples were taken from root canals of 80 teeth with pulp necrosis and primary endodontic infections in a Chinese population. DNA extracted from the samples was amplified by PCR with universal bacterial primers based on 16S rRNA gene sequences, and the products hybridized with the microarrays in which the specific oligonucleotide probes were added. The results of hybridization were screened by a confocal laser scanner. Pearson chi-square test and the two-sided Fisher exact test were used to analyse whether a significant association existed between the species and symptoms as well as in co-existence of two target organisms by a statistical software package (SAS 8.02). The 16S rRNA gene microarray detected at least one of the three test species in 76% of the study teeth. P. endodontalis, P. gingivalis and P. intermedia were found in 50%, 33% and 45%, respectively. A significant association was found in the presence of the pair P. endodontalis / P. gingivalis (P endodontalis (P endodontalis and P. gingivalis was also associated with the presence of a sinus tract (Pendodontalis were associated with the presence of sinus tract and abscess formation. © 2012 International Endodontic Journal.

  15. Substâncias de origem vegetal potencialmente úteis na terapia da asma

    Directory of Open Access Journals (Sweden)

    Maria Fernanda P. Corrêa

    Full Text Available A asma é uma doença inflamatória crônica, que representa um problema de saúde pública com altos números de óbitos e elevado impacto socioeconômico. A patologia é caracterizada pela fase imediata, mediada pela resposta aguda de células inflamatórias, e a tardia, que é responsável pela resposta com envolvimento de células específicas do sistema imunológico. Atualmente, os principais tipos de fármacos utilizados no tratamento da asma são os broncodilatadores e agentes antiinflamatórios, que aliviam os sintomas de broncoespasmo e diminuem a inflamação das vias aéreas. Entretanto, terapias com esses medicamentos não são totalmente eficazes e provocam efeitos adversos. A escassez de fármacos seguros e o baixo acesso da população carente aos tratamentos utilizados estimulam a busca de novas substâncias potencialmente úteis no tratamento da asma. Produtos naturais de origem vegetal representam um grande potencial farmacológico contra asma, uma vez que podem fornecer moléculas diversas com mecanismos específicos para tratamento e controle da patologia. A busca por terapias mais eficientes e específicas para o processo asmático mostra que a procura nos produtos naturais é promissora e possui um papel importante para a descoberta de novas terapias contra a asma.

    2008-10-01

    Full Text Available OBJETIVO: Este artigo revisa aspectos relevantes da fobia social e os estágios de tratamento através da terapia cognitivo-comportamental em crianças, adolescentes e adultos. MÉTODO: A partir do banco de dados Medline, realizou-se revisão da literatura publicada a respeito do tratamento da fobia social por meio da terapia cognitivo-comportamental. RESULTADOS: Revisão da literatura sugere que a fobia social é uma condição prevalente e crônica, caracterizada por inibição social e timidez excessiva. Tanto o diagnóstico como o tratamento desse transtorno são comumente determinados pelo nível de incômodo e pelo prejuízo funcional. Estudos populacionais indicam taxas de prevalência ao longo da vida para a fobia social entre 2,5 e 13,3%. As principais técnicas utilizadas na terapia cognitivo-comportamental para a fobia social são descritas e exemplificadas em um relato de caso. CONCLUSÕES: Há consenso geral na literatura de que a terapia cognitivo-comportamental é eficaz tanto para o tratamento de jovens como de adultos com fobia social. Uma vez que a fobia social com freqüência tem início precoce, a identificação de crianças com risco acentuado para o desenvolvimento de fobia social deve ser priorizada em investigações futuras.OBJECTIVE: This article reviews relevant aspects of social phobia and the stages of treatment within cognitive-behavioral therapy in children and adolescents, as well as in adults. METHOD: A review of the literature published on the treatment of social phobia using cognitive-behavioral treatments was performed using the Medline database. RESULTS: A review of the literature suggests that social phobia is a chronic and prevalent condition, characterized by social inhibition and excessive shyness. Diagnosis and treatment of the disorder are usually determined by distress level and functional impairment. Population studies indicate that lifetime prevalence rates for social phobia range from 2.5 to 13

    Eight ethanolic extracts of indigenous Taiwanese plants of the genus Alpinia were tested for tumor cytotoxicity against AGS, Hep G2, HeLa, KB, and HL-60 cells. Among the 50 % and 95 % EtOH extracts of eight Alpinia species, the cytotoxic effects of Alpinia intermedia leaves were the strongest. When the leaf extract of A. intermedia was partitioned using n -hexane and aqueous solvents, the n -hexane layer showed a greater cytotoxic effect and could prolong the survival time of P-388D 1 tumor-bearing CDF1 mice. Two new labdane diterpene derivatives, intermedin A ( 1 ) and intermedin B ( 2 ), and coronarin E ( 3 ) were isolated from the n -hexane layer of A. intermedia . Intermedin A induced apoptosis in HL-60 cells at 30 µg/mL and significantly prolonged the survival time of P-388D 1 tumor-bearing CDF 1 mice by 48.7 % at 20 mg/kg of body weight. We suggest that intermedin A is a major compound of A. intermedia and has a cytotoxic effect on HL-60 and P-388D 1 cells. Georg Thieme Verlag KG Stuttgart · New York.

    Full Text Available El análisis funcional del comportamiento verbal de tradición skinneriana ha encontrado desarrollos recientes en modelos de intervención conductual que son objeto de exposición y análisis en el presente estudio teórico. La Psicoterapia Analítico- Funcional (PAF se fundamenta en el análisis y moldeamiento del comportamiento verbal del paciente en tiempo real durante las sesiones de intervención. En este caso, la relación terapéutica se considera un modelo de relación interpersonal a generalizar a la vida diaria del cliente. La PAF ofrece un análisis conductual de la relación terapeuta-paciente y de su importancia en el proceso clínico, así como un marco teórico para el análisis de los efectos sinérgicos derivados de su combinación con terapias cognitivas o cognitivo-conductuales tradicionales. Por otro lado, la Terapia de Aceptación y Compromiso (ACT aborda los trastornos del comportamiento y las emociones enfatizando el análisis de la evitación de eventos privados aversivos (por ejemplo, evitación experiencial como función de una pluralidad de comportamientos de topografía «psicopatológica». Estos procesos pueden verse coadyuvados por el seguimiento de reglas verbales relativas al control estricto de emociones y cogniciones. La ACT ofrece varias herramientas clínicas para desmontar los procesos de evitación y de seguimiento de reglas asociados al problema del paciente. Finalmente, ambos modelos son analizados en términos de su continuidad teórica con el análisis funcional del comportamiento y el análisis de conducta tradicionales.

    In this study, the effects and underlying mechanisms of NCX 4040, a nitric oxide (NO)-donating aspirin derivative, on the production of proinflammatory mediators were examined using murine macrophages exposed to lipopolysaccharide (LPS) from Prevotella intermedia, a pathogen implicated in the etiology of periodontal disease. NCX 4040 significantly reduced P. intermedia LPS-induced production of inducible NO synthase (iNOS)-derived NO, IL-1β and IL-6 as well as their mRNA expression in RAW264.7 cells. Notably, NCX 4040 was much more effective than the parental compound aspirin in reducing LPS-induced production of inflammatory mediators. NCX 4040 induced the expression of heme oxygenase-1 (HO-1) in cells treated with P. intermedia LPS, and the suppressive effect of NCX 4040 on LPS-induced NO production was significantly reversed by SnPP, a competitive HO-1 inhibitor. NCX 4040 did not influence LPS-induced phosphorylation of JNK and p38. IκB-α degradation as well as nuclear translocation and DNA-binding activities of NF-κB p65 and p50 subunits induced by P. intermedia LPS were significantly reduced by NCX 4040. Besides, LPS-induced phosphorylation of STAT1 and STAT3 was significantly down-regulated by NCX 4040. Further, NCX 4040 elevated the SOCS1 mRNA in cells stimulated with LPS. This study indicates that NCX 4040 inhibits P. intermedia LPS-induced production of NO, IL-1β and IL-6 in murine macrophages through anti-inflammatory HO-1 induction and suppression of NF-κB, STAT1 and STAT3 activation, which is associated with the activation of SOCS1 signaling. NCX 4040 could potentially be a promising tool in the treatment of periodontal disease, although further studies are required to verify this. Copyright © 2015 Elsevier B.V. All rights reserved.

    Guido Pablo Korman

    2013-01-01

    Full Text Available El psicoanálisis en el que Beck se formó tenía como objetivo incluir al psicoanálisis dentro del modelo científico. Esto era consistente con los intereses de un gran número de investigadores clínicos en los Estados Unidos durante las décadas de 1950 y 1960. Este trayecto intelectual lo llevará, años después, a desarrollar la terapia cognitiva. En este trabajo nos enfocaremos en el entrenamiento psicoanalítico de Beck así como en las primeras publicaciones de éste como especialista en psiquiatría durante su práctica hospitalaria en la Clínica de Austen Riggs y en el Hospital Valley Forge Army. Analizaremos sus primeras hipótesis, intentando rastrear los indicios de su modo de actuar como psicoanalista. Esta misma formación posteriormente lo llevará a un replanteo del modelo psicoanalítico, hecho que será clave para explicar las características que adoptará la terapia cognitiva.

    Full Text Available Neste estudo objetivou-se analisar o processo de adesão à terapia antirretroviral e suas representações sociais para pessoas que vivem com HIV/AIDS. Trata-se de um estudo de natureza qualitativa e descritiva, elaborado à luz da Teoria das Representações Sociais. Participaram 30 pessoas em tratamento ambulatorial para HIV/AIDS em um hospital público do Rio de Janeiro. Os dados foram coletados por meio de entrevistas semiestruturadas e submetidos à análise de conteúdo temática. Observa-se que os eventos adversos decorrentes da terapia, o medo de ter a soropositividade revelada e o fato de não se perceber doente implicam o abandono da terapia, e que o amparo profissional e familiar é essencial para a que a pessoa prossiga com a terapia. Conclui-se que o processo de adesão evidencia um processo de mudanças simbólicas, do início do tratamento até sua estabilização, expresso em atitudes e imagens da doença, do vírus e dos medicamentos.

Se ausculto, ademas, a que vision del enfoque constructivista responden las expresiones de las maestras acerca de su practica educativa y como compara con su quehacer, a la luz de los elementos esenciales de las visiones constructivistas piagetiana, social y radical. Se utilizo el diseno de estudio descriptivo de caso multiple. El estudio se baso en entrevistas a profundidad, revision de documentos y observacion no participativa a la sala de clases. El contexto fueron tres escuelas publicas de la Region Educativa de San Juan, una elemental, una intermedia y una superior. Los resultados confirmaron que la transicion hacia el enfoque constructivista es un proceso que toma tiempo, dedicacion y la participacion en adiestramientos y readiestramientos acerca del nuevo enfoque. Las maestras coinciden en la mayoria de las practicas educativas que utilizan para implantar el enfoque constructivista de ensenanza y difieren en algunas debido, probablemente, a que han tenido que adaptarlas a los correspondientes niveles de ensenanza: elemental, intermedio y superior. Dos de las maestras planifican por conceptos generadores, mientras que una de ellas planifica siguiendo la guia que recibe del Departamento de Educacion. Difieren ademas, en el enfasis que confieren al inquirir cientifico. Con relacion a la correspondencia entre la vision manifestada por las maestras a la luz de las visiones piagetiana, social y radical, aparentemente, las preguntas del protocolo de entrevistas no lograron evocar la informacion con suficiente profundidad, por lo que la investigadora tuvo que inferir las visiones de las

    Full Text Available The worldwide incidence of head and neck cancer is, approximately, 640,000 new cases per year. Oral cancer accounts for one third of all cancers and it is the eighth most diagnosed in men. The most used treatments for these tumors are surgery, radiotherapy, chemotherapy, or a combination of these therapeutic modalities. Due to the large structural, functional and aesthetic impairment that conventional treatments cause, many studies seek new methods to replace or to assist the treatment of oral cancer. Photodynamic therapy (PDT is a promising new modality of cancer treatment that is already being used clinically.

The operative surgery used in these patients was gastrointestinal suture at any level and they were enterally fed. As soon as the intestinal dynamics was re-established, they were given enteral liquid feeding by continuos drip. This led to a reduction in parenteral nutrition, stay at hospital, parenteral nutrition complications, nosocomial infection complications from bacterial translocation, and in enteral inmunomodulation. In this way, quick recovery, improved weight gain, better quality of life, lower sequelae and mortality were reached, all of which resulted in lower costs.

    Extramedullary hematopoiesis (EMH) is a rare disorder, defined as the appearance of hematopoietic elements outside the bone marrow or peripheral blood. The most common sites of EMH are liver and spleen, but it has been documented in other organs such as the mediastinum, lymph nodes, breast, and central nervous system. EMH occurs as a compensatory mechanism for bone marrow dysfunction in severe thalassemia. We report a case of EMH presenting as a posterior mediastinal mass in a 34-year-old woman with thalassemia intermedia with chronic cough and shortness of breath on exertion. The diagnosis of EMH was confirmed by a CT-guided fine needle biopsy. All symptoms disappeared after surgical removal of the mass.

    Feasible biorefineries for production of second-generation ethanol are difficult to establish due to the process complexity. An alternative is to partially include the process in the first-generation plants. Whole stillage, a by-product from dry-mill ethanol processes from grains, is mostly composed of undegraded bran and lignocelluloses can be used as a potential substrate for production of ethanol and feed proteins. Ethanol production and the proteins from the stillage were investigated using the edible fungi Neurospora intermedia and Aspergillus oryzae, respectively. N. intermedia produced 4.7 g/L ethanol from the stillage and increased to 8.7 g/L by adding 1 FPU of cellulase/g suspended solids. Saccharomyces cerevisiae produced 0.4 and 5.1 g/L ethanol, respectively. Under a two-stage cultivation with both fungi, up to 7.6 g/L of ethanol and 5.8 g/L of biomass containing 42% (w/w) crude protein were obtained. Both fungi degraded complex substrates including arabinan, glucan, mannan, and xylan where reductions of 91, 73, 38, and 89% (w/v) were achieved, respectively. The inclusion of the current process can lead to the production of 44,000 m(3) of ethanol (22% improvement), around 12,000 tons of protein-rich biomass for animal feed, and energy savings considering a typical facility producing 200,000 m(3) ethanol/year.

    A methyl jasmonate responsive 3-carene synthase (Li3CARS) gene was isolated from Lavandula x intermedia and functionally characterized in vitro. Lavenders produce essential oils consisting mainly of monoterpenes, including the potent antimicrobial and insecticidal monoterpene 3-carene. In this study we isolated and functionally characterized a leaf-specific, methyl jasmonate (MeJA)-responsive monoterpene synthase (Li3CARS) from Lavandula x intermedia. The ORF excluding transit peptides encoded a 64.9 kDa protein that was expressed in E. coli, and purified with Ni-NTA agarose affinity chromatography. The recombinant Li3CARS converted GPP into 3-carene as the major product, with K m and k cat of 3.69 ± 1.17 µM and 2.01 s -1 respectively. Li3CARS also accepted NPP as a substrate to produce multiple products including a small amount of 3-carene. The catalytic efficiency of Li3CARS to produce 3-carene was over ten fold higher for GPP (k cat /K m = 0.56 µM -1 s -1 ) than NPP (k cat /K m = 0.044 µM -1 s -1 ). Production of distinct end product profiles from different substrates (GPP versus NPP) by Li3CARS indicates that monoterpene metabolism may be controlled in part through substrate availability. Li3CARS transcripts were found to be highly abundant in leaves (16-fold) as compared to flower tissues. The transcriptional activity of Li3CARS correlated with 3-carene production, and was up-regulated (1.18- to 3.8-fold) with MeJA 8-72 h post-treatment. The results suggest that Li3CARS may have a defensive role in Lavandula.

    Full Text Available OBJETIVO: O uso de tecnologia médica intervencionista em pacientes idosos em estado terminal necessita ser associado aos cuidados paliativos como medidas de suporte clínico na terapia intensiva. Esse recurso auxilia nas decisões ao final da vida do paciente e direciona a atenção da equipe de saúde para garantir o conforto do paciente e a satisfação da família. O prolongamento da vida sem a implementação de ações que visem amenizar sintomas, como dor e dispneia, contribui para o estresse familiar e a morte com sofrimento. O objetivo deste trabalho foi conhecer os avanços no uso dos cuidados paliativos na unidade de terapia intensiva. MÉTODOS: Revisão sistemática sobre a relação entre cuidados paliativos aos idosos e a terapia intensiva nos portais Medline e Bireme. RESULTADOS: Foram analisados 29 artigos, que mostram experiências de cuidados paliativos em unidades de terapia intensiva utilizando as variáveis "satisfação da família quando participa das discussões sobre os cuidados paliativos" e "dificuldades na implementação desse tipo de cuidado por falta de capacitação técnica dos profissionais". CONCLUSÃO: O tema "cuidados paliativos" deve ser aprofundado visando melhorar a relação entre pacientes, seus familiares e a equipe de saúde. Considerando o aumento do número de idosos na terapia intensiva, é fundamental melhorar a capacitação do profissional de saúde para enfrentar os desafios que envolvem a terminalidade da vida.

No Brasil, a Terapia Comunitária (TC vem sendo utilizada como tecnologia de cuidado de superação do sofrimento, favorecendo o fortalecimento e/ou a construção de vínculos, bem como de redes sociais. A partir do projeto de extensão do Departamento de Enfermagem de Saúde Pública e Psiquiatria da Universidade Federal da Paraíba, emergiu este estudo que objetivou conhecer as repercussões da Terapia Comunitária no cotidiano das pessoas, moradores da comunidade Ambulante, no Bairro de Mangabeira/ João Pessoa/ Paraíba/ Brasil. Utilizou-se o método de história oral temática, fazendo uso da técnica de entrevista para a coleta de dados, com nove participantes do grupo da Terapia Comunitária. Analisando o material empírico, identificou-se que os motivos que levaram os colaboradores a participar do grupo de TC foram: o convite feito pela equipe de saúde da família e a necessidade das pessoas em verbalizar as angústias e sofrimentos do cotidiano. As mudanças ocorridas no cotidiano dos colaboradores estão voltadas para uma maior compreensão de si e do outro e para a capacidade de transformação pessoal e social, bem como no fortalecimento dos vínculos: familiar, de amizade e espiritual. Destaca-se a construção dos vínculos de lazer, social e comunitário, a partir dos encontros de TC. Isto foi evidenciado pela conformação da rede de apoio social, a partir da mobilização dos participantes em busca de uma melhor qualidade de vida para si e para a comunidade. Consideramos que a TC se consolida como uma tecnologia de cuidado, que pode ser viabilizada pelas equipes de saúde da família, para a promoção da saúde, prevenção do sofrimento psíquico, fortalecimento de vínculos com a comunidade, construção de redes de apoio e inclusão social.

La tendencia actual hacia todo lo natural, las corrientes sobre cuidados de salud de las distintas culturas, unidas a las recomendaciones de la OMS a los enfermeros sobre la necesidad de utilizar los "métodos tradicionales y complementarios" para conseguir mejorar la salud de la población, hacen que la risoterapia sea una alternativa como instrumento opcional de cuidados. Planteamos una revisión bibliográfica con el objetivo de conocer la aplicación de la risoterapia en la salud y más concretamente en los cuidados enfermeros. Del análisis de los resultados podemos concretar que la risa se trabaja en diferentes ámbitos profesionales, no sólo en el sanitario. Es en el campo de la comunicación donde más se divulga esta terapia. Hemos encontrado pocas publicaciones de enfermería, pero muy valiosas ya que trabajan en el terreno de la investigación y de la docencia. Sería interesante que los profesionales de enfermería utilizaran esta terapia que mejora la calidad de los cuidados y ofrece un campo independiente propicio para la investigación.Related to complementary therapies, humour and laugh contribute to enhance health status and diminish illness situations.

    This study was performed to analyze the effect of carbon monoxide (CO)-releasing molecule-3 (CORM-3) in alleviating the production of proinflammatory mediators in macrophages treated with lipopolysaccharide (LPS) from Prevotella intermedia, a pathogen associated with periodontal disease, and its possible mechanisms of action. LPS was isolated using the hot phenol-water method. Culture supernatants were assayed for nitric oxide (NO) and interleukin-1β (IL-1β). Gene expression was quantified by real-time PCR, and protein expression by immunoblotting. DNA-binding activities of NF-κB subunits were determined using an ELISA-based kit. CORM-3 suppressed the production of inducible NO synthase (iNOS)-derived NO and IL-1β at both gene transcription and translation levels in P. intermedia LPS-activated RAW264.7 cells. CORM-3 enhanced heme oxygenase-1 (HO-1) expression in cells stimulated with P. intermedia LPS, and inhibition of HO-1 activity by SnPP notably reversed the suppressive effect of CORM-3 on LPS-induced production of NO. LPS-induced phosphorylation of p38 and JNK was not affected by CORM-3. CORM-3 did not influence P. intermedia LPS-induced degradation of IκB-α. Instead, nuclear translocation of NF-κB p65 and p50 subunits was blocked by CORM-3 in LPS-treated cells. In addition, CORM-3 reduced LPS-induced p65 and p50 binding to DNA. Besides, CORM-3 significantly suppressed P. intermedia LPS-induced phosphorylation of STAT1. Overall, this study indicates that CORM-3 suppresses the production of NO and IL-1β in P. intermedia LPS-activated murine macrophages via HO-1 induction and inhibition of NF-κB and STAT1 pathways. The modulation of host inflammatory response by CORM-3 would be an attractive therapeutic approach to attenuate the progression of periodontal disease. Copyright © 2015 Elsevier B.V.

    The dispersal and survival of the phlebotomines Nyssomyia intermedia and Nyssomyia neivai (both implicated as vectors of the cutaneous leishmaniasis agent) in an endemic area was investigated using a capture-mark-release technique in five experiments from August-December 2003 in municipality of Iporanga, state of São Paulo, Brazil. A total of 1,749 males and 1,262 females of Ny. intermedia and 915 males and 411 females of Ny. neivai were marked and released during the five experiments. Recapture attempts were made using automatic light traps, aspiration in natural resting places and domestic animal shelters and Shannon traps. A total of 153 specimens (3.48%) were recaptured: 2.59% (78/3,011) for Ny. intermedia and 5.35% (71/1,326) for Ny. neivai. Both species were recaptured up to 144 h post-release, with the larger part of them recaptured within 48 h. The median dispersion distances for Ny. intermedia and Ny. neivai, respectively, were 109 m and 100 m. The greatest dispersal range of Ny. intermedia was 180 m, while for Ny. neivai one female was recaptured in a pasture at 250 m and another in a pigsty at 520 m, showing a tendency to disperse to more open areas. The daily survival rates calculated based on regressions of the numbers of marked insects recaptured on the six successive days after release were 0.746 for males and 0.575 for females of Ny. intermedia and 0.649 for both sexes of Ny. neivai. The size of the populations in the five months ranged from 8,332-725,085 for Ny. intermedia males, 2,193-104,490 for Ny. intermedia females, 1,687-350,122 for Ny. neivai males and 254-49,705 for Ny. neivai females.

    Full Text Available OBJECTIVE: to conduct a systematic review of experimental and clinical studies evaluating the effect of hyperbaric oxygen therapy on the spinal cord injury. METHODS: ninety-three studies were identified in the database Pubmed. Among these, through a set of inclusion/exclusion criteria, 11 articles published between 1963 and 2009 were selected. In the nine experimental studies, different ways to apply the treatment were observed. The measured outcomes were: functional, histological, biochemical and electrophysiological. RESULTS: in most of the studies, the results show recovery of locomotor function, histology and/or biochemical features. Regarding the two studies in clinical samples, the results are controversial. The samples are heterogeneous and the application of hyperbaric oxygen therapy is not the same for all patients in each study. CONCLUSION: considering the results of this review, further studies are necessary to define the role of hyperbaric oxygen therapy in acute spinal cord injury.OBJETIVO: realizar una revisión sistemática de estudios experimentales y clínicos que evaluaban los efectos de la terapia hiperbárica en el traumatismo raquimedular.

    Full Text Available En la tradición del pensamiento occidental, la pregunta “¿Qué es el arte?” ha jugado un papel central, aunque enigmático, para el campo de la filosofía, donde se han avanzado tantas objeciones y respuestas tentativas, que hoy pareciera que han sido tantos esfuerzos sin rumbo ni asidero en el mundo real del arte. Este texto afronta la plausibilidad de asumir la pregunta “¿Qué es el arte?” como problema filosófico. Para responder a este cuestionamiento acudimos a Wittgenstein, con el fin de realizarle una terapia filosófica a la pregunta misma y así mostrar que los principales paradigmas filosóficos sobre este asunto no son sino la manifestación de una confusión del lenguaje en torno al término ‘arte’.

Se enfoca la teoría general de los ensueños desde Hipócrates hasta nuestros días, así como su interpretación, tanto del punto de vista psicológico como religioso y cultural. Se hace énfasis en la función terapéutica de los ensueños, tanto en la terapia freudiana como la jungiana y la gestáltica. Reflexiona sobre los aportes de Freud, Jung y Perls, ampliando los conceptos del ensueño de la terapia gestáltica, que considera el ensueño "como el camino real a la integración, siendo la producción humana más espontánea de la existencia. El ensueño es la expresión que nos llega sin intención, voluntad y deseo. El ensueño más absurdo no nos impacta en el mismo momento como algo absurdo, se siente como verdadero. El ensueño es mucho más que un deseo inconcluso, es un mensaje existencial muy claro acerca de lo que falta en nuestras vidas, lo que se evita hacer y vivir". Se ilustra el ensayo con un trabajo de ensueño con una paciente en la Clínica de Día, del Hospital Guillermo Almenara, empleando las técnicas gestálticas. El ensayo se circunscribe a una apreciación de la filosofía y praxis gestáltica sobre los ensueños.

    Marli B. Santos Ribeiro

    Full Text Available A assistência psiquiátrica brasileira, desde seu início, era baseada na internação dos doentes mentais em hospitais psiquiátricos e em sua exclusão social. Desde o final do regime militar, na década de oitenta, esta assistência vem passando por transformações que propõem o tratamento dos doentes mentais em serviços comunitários substitutivos ao hospital psiquiátrico. A profissão terapia ocupacional cuja prática voltava-se para a ocupação dos pacientes no interior dos hospitais, diante das transformações da assistência psiquiátrica, vem buscando um aprimoramento teórico técnico e político para a atuação nos serviços substitutivos, em nível de prevenção, promoção de saúde, tratamento, reabilitação e inclusão social. O presente trabalho tem como objetivo apresentar algumas práticas de terapia ocupacional baseadas em paradigmas que enfatizam a importância do tratamento e da inclusão do doente mental na sociedade, destacando-se uma experiência que vem sendo realizada em Botucatu-SP (Brasil, por uma organização não governamental. Conclui-se que a profissão, por congregar conhecimento interdisciplinar, e se ocupar das necessidades e dificuldades dos pacientes no cotidiano, apresenta um instrumental condizente com a assistência comunitária.

Com o objetivo principal de envolver os usuários com a natureza, tornando a atividade da horticultura uma terapia no tratamento das suas necessidades especiais. Antes pessoas com transtornos mentais eram excluídos, tidos como perturbadores da ordem social. Somente no final do século XVIII e iniciou do século XIX iniciou-se uma transformação na assistência psiquiátrica no Brasil e no mundo. Passando a reinseri-los na sociedade e ocupa-los com algo que evitasse a ociosidade. Correlacionamos nosso objeto de estudo de forma aliada aos processos de sustentabilidade que, por sua vez, implicam em uma reorganização social a partir da preocupação com o meio ambiente e suas relações no intuito de manter preservado os recursos naturais e ainda ampliar a qualidade de vida da sociedade. A horticultura como terapia envolve os usuários em um ambiente natural, resgata o conhecimento sobre o trato com a terra, estimula e aguça a imaginação, traz benefícios psicológico, social, nutricional e econômico, favorecendo, neste sentido o processo de construção crítica do conhecimento, aliados a práxis que alia ensino, pesquisa; extensão e, sobretudo, amplia as relações entre academia e comunidade. Neste sentido, compreendemos que esta prática transforma o espaço deixando mais arborizado, melhorando o microclima e sua biodiversidade que deixam o ambiente mais relaxante.

    Full Text Available The influence of monospecific feeding on the post-embryonic development of L. intermedia, L. laeta and L. gaucho was evaluated. Two hundred and ten spiderlings were individualized in containers (120 ml, 105 being fed with Tenebrio molitor larvae and 105 with Pycnoscelus surinamensis nymphs. In the three species, the number of molts varied according to the diet. The number of spiders that reached maturity was lower in L. gaucho. In L. intermedia, the duration of the post-embryonic period was greater when larvae are fed. Mortality was higher in the second instar in the three species, the highest frequency being registered for L. gaucho. The data provided evidence that monospecific feeding influenced the post-embryonic development of the studied species. This influence might intensified by specific characteristics such as origin, habits and habitats.

    The Gonghe Basin region of the Tibet Plateau is severely affected by desertification. Compared with other desertified land, the main features of this region is windy, cold and short growing season, resulting in relatively difficult for vegetation restoration. In this harsh environment, identification the spatial distribution of soil nutrients and analysis its impact factors after vegetation establishment will be helpful for understanding the ecological relationship between soil and environment. Therefore, in this study, the 12-year-old C. intermedia plantation on sand dunes was selected as the experimental site. Soil samples were collected under and between shrubs on the windward slopes, dune tops and leeward slopes with different soil depth. Then analyzed soil organic matter (SOM), total nitrogen (TN), total phosphorus (TP), total potassium (TK), available nitrogen (AN), available phosphorus (AP) and available potassium (AK). The results showed that the spatial heterogeneity of soil nutrients was existed in C. intermedia plantation on sand dunes. (1) Depth was the most important impact factor, soil nutrients were decreased with greater soil depth. One of the possible reasons is that windblown fine materials and litters were accumulated on surface soil, when they were decomposed, more nutrients were aggregated on surface soil. (2) Topography also affected the distribution of soil nutrients, more soil nutrients distributed on windward slopes. The herbaceous coverage were higher and C. intermedia ground diameter were larger on windward slopes, both of them probably related to the high soil nutrients level for windward slopes. (3) Soil "fertile islands" were formed, and the "fertile islands" were more marked on lower soil nutrients level topography positions, while it decreased towards higher soil nutrients level topography positions. The enrichment ratio (E) for TN and AN were higher than other nutrients, most likely because C. intermedia is a leguminous shrub.

    Prevotella intermedia is an oral bacterium implicated in a variety of oral diseases. Although internalization of this bacterium by nonphagocytic host cells is well established, the molecular players mediating the process are not well known. Here, the properties of a leucine-rich repeat (LRR) domain protein, designated AdpF, are described. This protein contains a leucine-rich region composed of 663 amino acid residues, and molecular modeling shows that it folds into a classical curved solenoid structure. The cell surface localization of recombinant AdpF (rAdpF) was confirmed by electron and confocal microscopy analyses. The recombinant form of this protein bound fibronectin in a dose-dependent manner. Furthermore, the protein was internalized by host cells, with the majority of the process accomplished within 30 min. The internalization of rAdpF was inhibited by nystatin, cytochalasin, latrunculin, nocodazole, and wortmannin, indicating that microtubules, microfilaments, and signal transduction are required for the invasion. It is noteworthy that preincubation of eukaryotic cells with AdpF increased P. intermedia 17 internalization by 5- and 10-fold for HeLa and NIH 3T3 fibroblast cell lines, respectively. The addition of the rAdpF protein was also very effective in inducing bacterial internalization into the oral epithelial cell line HN4, as well as into primary cells, including human oral keratinocytes (HOKs) and human umbilical vein endothelial cells (HUVECs). Finally, cells exposed to P. intermedia 17 internalized the bacteria more readily upon reinfection. Taken together, our data demonstrate that rAdpF plays a role in the internalization of P. intermedia 17 by a variety of host cells.

    Undifferentiated thyroid carcinoma (UTC) lacks an effective treatment. Boron neutron capture therapy (BNCT) is based on the selective uptake of {sup 10}B-boronated compounds by some tumours, followed by irradiation with an appropriate neutron beam. The radioactive boron originated ({sup 11}B) decays releasing {sup 7}Li, gamma rays and alpha particles, and these latter will destroy the tumour. In order to explore the possibility of applying BNCT to UTC we have studied the biodistribution of BPA. Animal Model: To develop an animal model of undifferentiated thyroid carcinoma (UTC), which may be useful to study of BNCT. The UTC human cell line ARO was implanted into the back of the nude mice. We performed successive passages in mouse after tumor culturing in order to obtain an animal model similar to the human tumor. We studied the kinetics and the tumoral histology, the capability to induce metastasis, the biokinetics of in vitro growth, as well as cytogenetic and molecular aspects. Histological specimens of tumor showed extensive viability with high mitotic activity. At 117 days, the tumors reached a size of 1700 mm{sup 3} and showed a central necrotic portion with a thin layer of viable cells presence of micro metastasis could be observed in the lung. The kinetics of growth both in vivo and in vitro showed that when the number of passages in mouse increases the growth rate decreases. The cytogenetic and molecular studies did not show differences between the original line and the sublines that could explain this phenotypic change. Moreover, the cytogenetic studies proved that the ARO cell line and its sublines showed a complex clonal karyotype including structural alterations with deletions and translocations involving chromosomes 5, 7, 8, 9p, 11p, 17q 19p, and 20q that were consistent with earlier reported data in UTC. In vivo BNCT studies: ARO cells were transplanted into the scapular region of NIH nude mice, and after 2 weeks BPA (350 or 600 mg/kg bw) was injected via i.p. The animals were sacrificed between 30 and 150 min after the injection. With 350 mg, tumor uptake was highest after 60 min and the tumour/normal thyroid and tumour/blood ratios were 3 and 5, respectively. When 600 mg/kg bw BPA were administered, after 90 min. the tumor/ blood, tumor/ normal thyroid and tumor/ distal skin ratios for {sup 10}B concentrations/g tissue were approximately 3, showing a selective uptake by the tumor. Conclusions: This work provides an animal model of UTC pheno and geno typically similar to the original human tumor, which may be useful to explore BNCT. The present BNCT experimental results open the possibility of applying BNCT for the treatment of UTC. (author)
