Description and phylogenetic analysis of the Calycopidina (Lepidoptera, Lycaenidae, Theclinae, Eumaeini): a subtribe of detritivores

Description and phylogenetic analysis of the Calycopidina (Lepidoptera, Lycaenidae, Theclinae, Eumaeini): a subtribe of detritivores. The purpose of this paper is to establish a phylogenetic basis for a new Eumaeini subtribe that includes those lycaenid genera in which detritivory has been recorded. Morphological characters were coded for 82 species of the previously proposed "Lamprospilus Section" of the Eumaeini (19 of these had coding identical to another species), and a phylogenetic analysis was performed using the 63 distinct ingroup terminal taxa and six outgroups belonging to four genera. Taxonomic results include the description in the Eumaeini of Calycopidina Duarte & Robbins new subtribe (type genus Calycopis Scudder, 1876), which contains Lamprospilus Geyer, Badecla Duarte & Robbins new genus (type species Thecla badaca Hewitson), Arzecla Duarte & Robbins new genus (type species Thecla arza Hewitson), Arumecla Robbins & Duarte, Camissecla Robbins & Duarte, Electrostrymon Clench, Rubroserrata K. Johnson & Kroenlein revalidated status, Ziegleria K. Johnson, Kisutam K. Johnson & Kroenlein revalidated status, and Calycopis. Previous "infratribe" names Angulopina K. Johnson & Kroenlein, 1993, and Calycopina K. Johnson & Kroenlein, 1993, are nomenclaturally unavailable and polyphyletic as proposed. New combinations include Badecla badaca (Hewitson), Badecla picentia (Hewitson), Badecla quadramacula (Austin & K. Johnson), Badecla lanckena (Schaus), Badecla argentinensis (K. Johnson & Kroenlein), Badecla clarissa (Draudt), Arzecla arza (Hewitson), Arzecla tarpa (Godman & Salvin), Arzecla canacha (Hewitson), Arzecla calatia (Hewitson), Arzecla tucumanensis (K. Johnson & Kroenlein), Arzecla sethon (Godman & Salvin), Arzecla nubilum (H. H. Druce), Arzecla paralus (Godman & Salvin), Arzecla taminella (Schaus), Arzecla albolineata (Lathy), Electrostrymon denarius (Butler & H.Druce), Electrostrymon guzanta (Schaus), Electrostrymon perisus (H. H. Druce), Rubroserrata mathewi (Hewitson), Rubroserrata ecbatana (Hewitson), Kisutam micandriana (K. Johnson), and Kisutam syllis (Godman & Salvin). The structure of the male genitalia lateral window, labides, and brush organs are described and discussed, as are the female genitalia signa of the corpus bursae and 8th abdominal tergum. Widespread wing pattern sexual dimorphism in the Calycopidina is noted and illustrated, and the presence of alternating dark and light bands on the ventral wings of both sexes is discussed. The evidence for detritivory in Lamprospilus, Badecla, Arzecla, Arumecla, Camissecla, Electrostrymon, Ziegleria, Kisutam, and Calycopis is summarized using the new classification.

Phylogeny and Taxonomy of the Neotropical Thepytus (Lepidoptera: Lycaenidae: Theclinae)

The Neotropical lycaenid hairstreak genus Thepytus Robbins and its eight species are revised. Species treatments summarize nomenclature, distribution, habitat, behavior, and diagnostic traits, as well as noting why each species is considered distinct under a biological species concept. An identification key for males and a checklist are included. Beatheclus Balint & Dahners new synonym is synonymized with Thepytus, and Theppus beatrizae (Balint & Dahners) is a new combination. Other nomenclatural actions include the description of Thepytus jennifer Busby & Robbins new species. Thepytus nancyana Busby & Robbins new species, and Thepytus carmen Robbins & Duarte new species. A lectotype is designated or Thecla thyrea Hewitson, 1867, to ensure stability of this name. A phylogenetic analysis based on 22 coded morphological characters yields one equal weight most parsimonious 39-step tree. Implied weighting does not change the tree topology. Unambiguous changes in elevation optimized on the cladogram show that a montane lineage of Thepytus colonized the lowlands in at least one instance. The use of T. echelta (Hewitson) as a biological control agent for Psittacanthus (Loranthaceae) is discussed.

Updated Clinical Classification of Pulmonary Hypertension

The aim of a clinical classification of pulmonary hypertension (PH) is to group together different manifestations of disease sharing similarities in pathophysiologic mechanisms, clinical presentation, and therapeutic approaches. In 2003, during the 3rd World Symposium on Pulmonary Hypertension, the clinical classification of PH initially adopted in 1998 during the 2nd World Symposium was slightly modified. During the 4th World Symposium held in 2008, it was decided to maintain the general architecture and philosophy of the previous clinical classifications. The modifications adopted during this meeting principally concern Group 1, pulmonary arterial hypertension (PAH). This subgroup includes patients with PAH with a family history or patients with idiopathic PAH with germline mutations (e. g., bone morphogenetic protein receptor-2, activin receptor-like kinase type 1, and endoglin). In the new classification, schistosomiasis and chronic hemolytic anemia appear as separate entities in the subgroup of PAH associated with identified diseases. Finally, it was decided to place pulmonary venoocclusive disease and pulmonary capillary hemangiomatosis in a separate group, distinct from but very close to Group 1 (now called Group 1`). Thus, Group 1 of PAH is now more homogeneous. (J Am Coll Cardiol 2009;54:S43-54) (C) 2009 by the American College of Cardiology Foundation

Diagnosis, Assessment, and Treatment of Non-Pulmonary Arterial Hypertension Pulmonary Hypertension

The 4th World Symposium on Pulmonary Hypertension was the first international meeting to focus not only on pulmonary arterial hypertension (PAH) but also on the so-called non-PAH forms of pulmonary hypertension (PH). The term ""non-PAH PH"" summarizes those forms of PH that are found in groups 2 to 5 of the current classification of PH, that is, those forms associated with left heart disease, chronic lung disease, recurrent venous thromboembolism, and other diseases. Many of these forms of PH are much more common than PAH, but all of them have been less well studied, especially in terms of medical therapy. The working group on non-PAH PH focused mainly on 4 conditions: chronic obstructive lung disease, interstitial lung disease, chronic thromboembolic PH, and left heart disease. The medical literature regarding the role of PH in these diseases was reviewed, and recommendations regarding diagnosis and treatment of PH in these conditions are provided. Given the lack of robust clinical trials addressing PH in any of these conditions, it is important to conduct further studies to establish the role of medical therapy in non-PAH PH.

Ancient missense mutations in a new member of the RoRet gene family are likely to cause familial Mediterranean fever

Familial Mediterranean fever (FMF) is a recessively inherited disorder characterized by dramatic episodes of fever and serosal inflammation. This report describes the cloning of the gene likely to cause FMF from a 115-kb candidate interval on chromosome 16p. Three different missense mutations were identified in affected individuals, but not in normals. Haplotype and mutational analyses disclosed ancestral relationships among carrier chromosomes in populations that have been separated for centuries. The novel gene encodes a 3.7-kb transcript that is almost exclusively expressed in granulocytes. The predicted protein, pyrin, is a member of a family of nuclear factors homologous to the Ro52 autoantigen. The cloning of the FMF gene promises to shed light on the regulation of acute inflammatory responses.

Predicting the HER2 status of breast cancer from basic histopathology data: an analysis of 1500 breast cancers as part of the HER2000 International Study

The tests that are currently available for the measurement of overexpression of the human epidermal growth factor-2 (HER2) in breast cancer have shown considerable problems in accuracy and interlaboratory reproducibility. Although these problems are partly alleviated by the use of validated, standardised 'kits', there may be considerable cost involved in their use. Prior to testing it may therefore be an advantage to be able to predict from basic pathology data whether a cancer is likely to overexpress HER2. In this study, we have correlated pathology features of cancers with the frequency of HER2 overexpression assessed by immunohistochemistry (IHC) using HercepTest (Dako). In addition, fluorescence in situ hybridisation (FISH) has been used to re-test the equivocal cancers and interobserver variation in assessing HER2 overexpression has been examined by a slide circulation scheme. Of the 1536 cancers, 1144 (74.5%) did not overexpress HER2. Unequivocal overexpression (3+ by IHC) was seen in 186 cancers (12%) and an equivocal result (2+ by IHC) was seen in 206 cancers (13%). Of the 156 IHC 3+ cancers for which complete data was available, 149 (95.5%) were ductal NST and 152 (97%) were histological grade 2 or 3. Only 1 of 124 infiltrating lobular carcinomas (0.8%) showed HER2 overexpression. None of the 49 'special types' of carcinoma showed HER2 overexpression. Re-testing by FISH of a proportion of the IHC 2+ cancers showed that only 25 (23%) of those assessable exhibited HER2 gene amplification, but 46 of the 47 IHC 3+ cancers (98%) were confirmed as showing gene amplification. Circulating slides for the assessment of HER2 score showed a moderate level of agreement between pathologists (kappa 0.4). As a result of this study we would advocate consideration of a triage approach to HER-2 testing. Infiltrating lobular and special types of carcinoma may not need to be routinely tested at presentation nor may grade 1 NST carcinomas in which only 1.4% have been shown to overexpress HER2. Testing of these carcinomas may be performed when HER2 status is required to assist in therapeutic or other clinical/prognostic decision-making. The highest yield of HER2 overexpressing carcinomas is seen in the grade 3 NST subgroup in which 24% are positive by IHC. (C) 2003 Elsevier Science Ltd. All rights reserved.

High frequency of BRAF mutations in nevi

To evaluate the timing of mutations in BRAF (v-raf murine sarcoma viral oncogene homolog B1) during melanocytic neoplasia, we carried out mutation analysis on microdissected melanoma and nevi samples. We observed mutations resulting in the V599E amino-acid substitution in 41 of 60 (68%) melanoma metastases, 4 of 5 (80%) primary melanomas and, unexpectedly, in 63 of 77 (82%) nevi. These data suggest that mutational activation of the RAS/RAF/MAPK pathway in nevi is a critical step in the initiation of melanocytic neoplasia but alone is insufficient for melanoma tumorigenesis.

Practical software improve design and performance of a randomly packed air stripping column for removing volatile organic compounds from water

STRIPPING is a software application developed for the automatic design of a randomly packing column where the transfer of volatile organic compounds (VOCs) from water to air can be performed and to simulate it’s behaviour in a steady-state. This software completely purges any need of experimental work for the selection of diameter of the column, and allows a choice, a priori, of the most convenient hydraulic regime for this type of operation. It also allows the operator to choose the model used for the calculation of some parameters, namely between the Eckert/Robbins model and the Billet model for estimating the pressure drop of the gaseous phase, and between the Billet and Onda/Djebbar’s models for the mass transfer. Illustrations of the graphical interface offered are presented.

Transferência de massa através de arrastamento por ar: resultados de simulação laboratorial e numérica

O tolueno tem uma vasta aplicação industrial e apresenta alguns riscos para a saúde humana. Legislação comunitária, recentemente publicada, exige que se cumpra a médio prazo padrões mínimos de qualidade apontando como limite máximo de concentração de tolueno na água destinada a consumo humano o valor de 1 ppm. O processo de arrastamento por ar em colunas com enchimento desordenado é uma das técnicas de remoção disponíveis, embora ainda pouco implementada no nosso país. Neste trabalho simulou-se, laboratorial e numericamente, a remoção do tolueno da água através desta tecnologia sob condições operatórias pré-estabelecidas. A simulação à escala laboratorial foi executada numa instalação piloto constituída por uma coluna de vidro acrílico com 0.137metros de diâmetro interno preenchida desordenadamente com anéis Raflux de polietileno com 15milímetros de calibre numa altura de 1.10 metros. A experimentação efectuada abrangeu ensaios realizados quer em regime permanente quer em regime transitório. As simulações numéricas do comportamento de uma coluna com idênticas características, em estado estacionário e em estado transiente, foram efectuadas com “software” específico concebido para MatLab. Este software permite a descrição do regime hidrodinâmico e da transferência de massa deste processo de acordo com os modelos de Robbins [Robbins, 1991] e Onda [Onda, 1968], respectivamente, inseridos num modelo global fenomenológico traduzido num sistema de equações às derivadas parciais de 1ª ordem, do tipo hiperbólico, com uma variável espacial axial e uma variável temporal. A resolução deste modelo é efectuada através de algoritmos e estratégias específicas nomeadamente a implementação numérica dos métodos explícito de Euler para resolução do sistema de ED0s que traduz o estado estacionário primitivo e de diferenças finitas com esquema explícito associado a manipulação de matrizes esparsas para resolução do sistema de EDPs que traduz o estado dinâmico. A concordância entre os resultados obtidos na teoria e na prática, pese embora as dificuldades encontradas no controlo analítico das amostras, permite concluir que o modelo proposto possui um rigor fenomenológico suficiente e que o modelo numérico associado possibilita um elevado grau de exactidão e de fiabilidade. A aplicação desenvolvida pode constituir uma importante ferramenta de apoio à análise dinâmica desta operação unitária à escala industrial, reduzindo o esforço experimental e os respectivos custos associados. Constitui igualmente a base para uma implementação de um potencial sistema de controlo por actuação antecipada com base num modelo que reveste a forma de um sistema de parâmetros distribuídos.

Las dificultades en el cambio generacional en la dirección de PYMES familiares de la ciudad de Córdoba y su relación con el estilo de liderazgo y la valoración de competencias directivas por parte de dueños y/o gerentes de primera línea.

La administración estratégica está dominada por enfoques que consideran que el capital intelectual y el capital humano son fuente de ventaja competitiva (Brooking, 1996; Storey, 2007). Nuestro enfoque son competencias como activo intangible capaz de generar una ventaja competitiva sostenible en el tiempo. Estudiamos competencias directivas siguiendo el modelo del IESE (Abad Guerrero y Castillo Clavero, 2004). Los estudios previos tienden a enfocarse en grandes empresas; pero Larry Greiner (1998) había señalado que las prácticas de dirección que funcionan bien en una etapa de una empresa pueden desatar una crisis en otra. Por eso nos enfocamos en pymes, atendiendo a la gestión de implementación de sistemas ERP para la formalización de la gestión; al respecto, los líderes y sus diversas mezclas de competencias son un factor fundamental (Kroemmergard y Rose, 2002). En Argentina el 70% de las pymes son familiares (Davis, 2011). Mundialmente apenas el 8% de los negocios de familia alcanzan la tercera generación (Gallo, 1998; Barbeito y otros, 2004; Thornton, 2005; Kertész y otros, 2006; Müller, 2008); los trabajos sobre sucesión y relaciones familiares son los más publicados (Basco Rodrigo, et al., 2006). Para Fernández (2000) el fracaso de muchas pymes puede relacionarse con el estilo de liderazgo. El liderazgo es un tema de interés en la teoría y práctica administrativa actual (Hersey, Blanchard y Johnson, 2001; Storey, 2004; Robbins, 2004; Bass y Riggio, 2006, Yukl, 2008). Interesa el desafío que implica la dirección de empresas con diversas generaciones (García Lombardía, Stein y Pin, 2008). Observamos necesaria una investigación multidimensional que articule: estilo de liderazgo y valoración de competencias directivas por parte de dueños y/o gerentes de primera línea, con relación a las dificultades en la gestión del cambio generacional en la dirección de pymes familiares, atendiendo a las etapas de crecimiento de estas empresas y la aplicación de las TICs a la formalización de la gestión. Nuestra conjetura: las dificultades en la gestión del cambio generacional en la dirección de pymes familiares de la ciudad de Córdoba estarían relacionadas con el estilo de liderazgo y la valoración de competencias directivas intratégicas y de eficacia personal por parte de dueños y/o gerentes de primera línea de esas empresas. Planificamos una investigación de campo, no experimental, de dos etapas: exploratoria y asociativa; con diseño de investigación transaccional.
