Gene amplification in Rhynchosciara (1955-1987)

A review is made of the evidence indicating the existence of gene amplification in Rhynchosciara, from the early cytological work to the more recent studies using cloned sequences from the DNA puffs. Mention is made of work still in progress which indicates that the transcription unit of a DNA puff is surprisingly complex.

First report of Mazocroeoides georgei price, 1936 and Mazocraeoides opisthonema Hargis, 1955 in Brazil with new synonysms (Monogenea, Mazocraeidae)

Mazocraeoides georgei price, 1936 and mazocraeoides opisthonema Hargis, 1955 are reported for the first time in Brazil in Brevoortia aurea (Spix, 1829) and in Harengula clupeola (Cuvier, 1829) respectively, clupeid fishes from the littoral of Rio de janeiro State, which represent new host records. Mazocraeoides olentangiensis Sroufe, 1958 and mazocraeoides hargisi Price, 1961 are considered new synonyms for Mazocraeoides georgei.

Estudo sobre os Ceratopogonídeos de Minas Gerais: I - Descrição dos machos de Heteromyia chaquensis Duret & Lane, 1955 e Dasyhelea paulistana Forattini & Rabello, 1957 (Diptera, Ceratopogonidae)

This paper describes some results of a systematic survey of the Ceratopogonidae midges of the State of Minas Gerais, Brazil. Three species, Stilobezzia punctulata Lane, 1947, Heteromyia chaquensis Duret & Lane, 1955 and Dasyhelea paulistana Forattini & Rabello, 1957 were identified from a small lake, "Lagoinha" or "Olhos d'Água", near to the main lake of Lagoa Santa. The first descriptions of the males of Heteromyia chaquensis and Dasyhelea paulistana are presented.

The authors present the list of the species caught in the National Parks of Ubajara and Sete Cidades, in the counties of Ubajara (CE) and Piracuruca (PI), respectively, and described the Lutzomyia (Helcocyrtomyia) samueli (Deane, 1955) female, which up to now had been known by the male.

Neohilgertia venusti Gen. N. SP. N. (Nematoda: Oxyuridae)from Thylamys venustus cinderellus (Thomas) Reig, Kirsch & Marshall, 1985 (Marsupialia: Didelphidae) in Burruyacu, Tucuman, Argentina - Systematic position and possible evolution

Neohilgertia gen. n. proposed for Oxyuridae nematodes from Thylamys venustus cinderellus (Marsupialia: Didelphidae) is described. The hypothesis about the possibility of a secondary parasitism for marsupials and the origin of the genus in the African Sciuridae parasite ancestors is discussed.

Series enlazadas de algunos agregados económicos nacionales y regionales, 1955-2007 Versión 2.1

I construct "homogeneous" series of GVA at current and constant prices, employment and population for the Spain and its regions covering the period 1955-2007. The series are obtained by linking the Regional Accounts of the National Statistical Institute with the series constructed by Julio Alcaide and his team for the BBVA Foundation. The "switching point" at which this last source stops being used as a reference to construct the linked series is determined using a procedure that allows me to estimate which of the two competing series would produce an estimator with the lowest MSE when it is used as dependent variable in a regression on an arbitrary independent variable. To the extent that it is possible, the difference between the two series found at the point of linkage is distributed between the initial levels of the older series and its subsequent growth using external estimates of the relevant variables at the beginning of the sample period.

On some family related parasites (Nematoda, Cucullanidae) from the marine fish Paralonchurus brasiliensis (Steindachner, 1875) (Pisces, Ostraciidae)

Dichelyne (Cucullanellus) elongatus (Tornquist, 1931) Petter, 1974 and Cucullanus pulcherrimus Barreto, 1918, from Paralonchurus brasiliensis (Steind., 1875) are redescribed and two specimens of Dichelyne (Cucullanellus) sp. are also reported in this host, despite lack of previously, was again identified in Brazil since its original description and posterior illustration. The present findings represent also a new host record for the referred genera: Dichelyne Jagerskiold, 1902 and Cucullanus Mueller, 1777. D. (C.) elongatus is also referred in Brazil for the first time.

Series anuales de algunos agregados económicos y demográficos regionales, 1955-2009 (RegDat versión 2.3)

En una serie de trabajos anteriores he construido series largas de diversos agregados económicos regionales enlazando las distintas bases de la Contabilidad Regional de España entre sí y con las series históricas elaboradas por la Fundación BBVA. Puesto que esta última fuente sólo ofrece datos para años impares, las series enlazadas heredan esta característica desde 1955 hasta 1989. En la presente nota se construyen series anuales completas de las variables de interés utilizando un sencillo procedimiento de interpolación que incorpora la información anual disponible a nivel nacional para estas variables.

Ultrastructural aspects of spermatogonesis in Metamicrocotyla macracantha (Alexander, 1954) Koratha, 1955 (Monogenea; Microcotylidae)

Ultrastructural aspects of spermatogenesis, spermiogenesis and of the mature spermatozoon of a microcotylid monogenean Metamicrocotyla macracantha parasite from Mugil liza, are described. The irregularly-shaped spermatogonia divides by successive mitoses, forming the primary spermatocytes, identified by the presence of synaptonemal complexes in their nuclei. The spermatids formed by meiotic cell divisions of the secondary spermatocytes, differentiate into a mature spermatozoon. Cross sections of the head and the middle region of mature spermatozoa show the nucleus with strong condensed chromatin, the mitochondria with short cristae, peripheral microtubules and two axonemes with a 9+1 pattern, confirming the characteristics of this genus.

Obésité en Suisse: percentiles d'indice de masse corporelle (IMC) d'une population d'enfants et d'adolescents nés en 1980 à Lausanne et écart avec les normes suisses (1955)

OBJECTIVES: The objective of this study is to calculate the percentiles of BMI of a cohort of 1,203 children and adolescents, representing the 95% of the pupils of the school, born in 1980 followed longitudinally between 5 and 16 years. We compare these percentiles with those of the first swiss study, calculated on a cohort born in 1954-1956. METHODS: The percentiles were calculated with the method of Cole, on the basis of weight and height measured during the controls by the school health service, at a non-periodic mean interval of 14 months. RESULTS: The gap between the BMI percentiles of the two cohorts is near zero for the third percentiles, weak but progressively growing with age up to two units of BMI for the 50th percentiles. For the percentiles 97 the difference, straight away present at five years, grows regularly up to 11 years, and remains thereafter for the girls at 4.3 units of BMI, while growing more up to 6.8 units of BMI at 15 years for the boys. The percentages of children and adolescents of the present study with overweight, in accordance with the thresholds of Cole, constant for the girls at 14%, increase for the five to 11.5 years old boys from 13.4% to 17.6% for the 11.5 to 16 years old. The percentage of obesity is 2.7% for the girls, and increase for the same categories for the boys from a percentage of 1.7% to 2.3% for the boys. CONCLUSIONS: The changes during this quarter of century are important, especially for the boys. We can postulate thereafter a very early change in the energy balance. A chronic increase of the food supply, linked or not with a decrease of the physical activity, would be an explanation.

Th1 and Th17 hypercytokinemia as early host response signature in severe pandemic influenza.

INTRODUCTION Human host immune response following infection with the new variant of A/H1N1 pandemic influenza virus (nvH1N1) is poorly understood. We utilize here systemic cytokine and antibody levels in evaluating differences in early immune response in both mild and severe patients infected with nvH1N1. METHODS We profiled 29 cytokines and chemokines and evaluated the haemagglutination inhibition activity as quantitative and qualitative measurements of host immune responses in serum obtained during the first five days after symptoms onset, in two cohorts of nvH1N1 infected patients. Severe patients required hospitalization (n = 20), due to respiratory insufficiency (10 of them were admitted to the intensive care unit), while mild patients had exclusively flu-like symptoms (n = 15). A group of healthy donors was included as control (n = 15). Differences in levels of mediators between groups were assessed by using the non parametric U-Mann Whitney test. Association between variables was determined by calculating the Spearman correlation coefficient. Viral load was performed in serum by using real-time PCR targeting the neuraminidase gene. RESULTS Increased levels of innate-immunity mediators (IP-10, MCP-1, MIP-1beta), and the absence of anti-nvH1N1 antibodies, characterized the early response to nvH1N1 infection in both hospitalized and mild patients. High systemic levels of type-II interferon (IFN-gamma) and also of a group of mediators involved in the development of T-helper 17 (IL-8, IL-9, IL-17, IL-6) and T-helper 1 (TNF-alpha, IL-15, IL-12p70) responses were exclusively found in hospitalized patients. IL-15, IL-12p70, IL-6 constituted a hallmark of critical illness in our study. A significant inverse association was found between IL-6, IL-8 and PaO2 in critical patients. CONCLUSIONS While infection with the nvH1N1 induces a typical innate response in both mild and severe patients, severe disease with respiratory involvement is characterized by early secretion of Th17 and Th1 cytokines usually associated with cell mediated immunity but also commonly linked to the pathogenesis of autoimmune/inflammatory diseases. The exact role of Th1 and Th17 mediators in the evolution of nvH1N1 mild and severe disease merits further investigation as to the detrimental or beneficial role these cytokines play in severe illness.
