Composición en ácidos grasos de huevos y larvas de dentón (Dentex dentex L.) de hasta 40 días en condiciones de cultivo

Total lipid content and fatty acid (FA) composition of common dentex eggs spawned at different times and larvae reared under different culture conditions until 40 days post hatch (dph) were analysed in order to get a general pattern of lipid composition during larval development. Results were grouped according to the developmental stage of the larvae instead of age in dph. Saturated and monounsaturated fatty acids decreased along larval development, while polyunsaturated fatty acid (PUFA) content increased. The ratio of docosahexaenoic acid (DHA) / eicosapentaenoic acid (EPA) shifted from 4 – 5 in early developmental stages to lower than 1 after metamorphosis. Results suggest a subdivision of the larval development into two stages of opposite FA requirements.

On Machadosentis travassosi n. g., n. sp. (Eoacanthocephala: Quadrigyridae) parasite of a moray Gymnothorax ocellatus in Brazil

Machadosentis travassosi n. g., n. sp. an acanthocephalan parasite of a moray are proposed after comparison with the related genera in Quadrigyridae VVan Cleave, 1920. The new genus differs from the other related by the arrangement of proboscis hooks (five circles of rows with five hooks each, with well developed roots) besides the distribution of cuticular spines.

Revision of the genus Vampirolepis Spasskij, 1954 (Cestoda: Hymenolepididae)

The genus Vampirolepis Spasskij, 1954 is re-defined on the basis of the original description and the first detailed redescription by Andreiko et al. (1969). A restricted definitions is proposed, the main features being the arrangement of testicles on a straight line snd numerous hooks of fraternoid shape. Other important characters are the strobila with numerous proglottids, the cirrus pouch of moderate size and the cirrus, smooth or armed with minute spines. Formerly included Hymenolepidid cestodes with reduced strobila, particularly long cirrus pouch and different arrangement of gonads do not belong to Vampirolepis. Members of Vampirolepis in the restricted sense show a cosmopolitan repartition and parasitize only bats. The author does not accept the synonymy of Rodentolepis Spasskiji, 1954 with Vampirolepis. A tentative list of the species belonging to the genus is proposed.

Raillietina (Raillietina) guaricana n. sp. (Cestoda-Davaineidae), parasite of wild rats from the environmental protection area of Guaricana, Paraná, Brazil

Raillietina (Raillietina) guaricanae n. sp. is described from the wild rats Oryzomys intermedius, O. nigripes and O. ratticeps, captured in the Environmental Protection Area of Guaricana, from November 1988 to December 1989. Raillietina (Railietina) guaricanae n. sp. is closely related to the Neotropical mammalian Raillietina, however it differs by the fewer number of rostellar hooks, and tests different number of eggs capsules and host species. The number of known species of Raillietina (Raillietina), parasites of mammals in the Neotropical Region, is increased to four.

Nouveautés en médecine ambutatoire: dépistage, traitement et iatrogénicité [Innovations in ambulatory care: screening, treatment and iatrogenicity]

Cette année, six études utiles pour la pratique ont été retenues. L'indication à la mammographie entre 40 et 49 ans devrait être évaluée individuellement et en tenant compte des risques/bénéfices de cet examen. Au-delà de 65 ans, un dépistage systématique de la fibrillation auriculaire avec prise de pouls puis ECG (si pouls irrégulier) pourrait être réalisé de manière systématique. Les risques de complications postcolonoscopie existent, particulièrement suite à des biopsies/polypectomies, et ce risque devrait être discuté. Les inhibiteurs de la pompe à protons au long court sont un facteur de risque de fracture de hanche. S'il est important de prendre en charge des pressions artérielles élevées au-delà de 80 ans, il faut être prudent (orthostatisme). Une corticothérapie précoce suite à une paralysie faciale périphérique est efficace. This year we have selected six studies useful for the day to day practice. A mammography in women 40 to 49 years of age should be evaluated taking into account the patient's profile and the possible risks and benefits of this exam. In patients over 65 years of age, a systematic atrial fibrillation screening, with pulse rate measuring then ECG (if irregular beat) should be realised on a regular basis. The risks for complications following colonoscopies do exist, especially after biopsies/polypectomies and this risk should be discussed. Long term proton pump inhibitor treatment is a risk factor for hip fracture. It is important to treat high blood pressure problems in the elderly, but the orthostatic risks should be adressed. A corticoid treatment started quickly for Bell's palsy is efficient

Identification and analysis of functional elements in 1% of the human genome by the ENCODE pilot project.

We report the generation and analysis of functional data from multiple, diverse experiments performed on a targeted 1% of the human genome as part of the pilot phase of the ENCODE Project. These data have been further integrated and augmented by a number of evolutionary and computational analyses. Together, our results advance the collective knowledge about human genome function in several major areas. First, our studies provide convincing evidence that the genome is pervasively transcribed, such that the majority of its bases can be found in primary transcripts, including non-protein-coding transcripts, and those that extensively overlap one another. Second, systematic examination of transcriptional regulation has yielded new understanding about transcription start sites, including their relationship to specific regulatory sequences and features of chromatin accessibility and histone modification. Third, a more sophisticated view of chromatin structure has emerged, including its inter-relationship with DNA replication and transcriptional regulation. Finally, integration of these new sources of information, in particular with respect to mammalian evolution based on inter- and intra-species sequence comparisons, has yielded new mechanistic and evolutionary insights concerning the functional landscape of the human genome. Together, these studies are defining a path for pursuit of a more comprehensive characterization of human genome function.

Neotropical Monogenoidea. 23. Two new species of Gyrodactylus (Gyrodactylidae) from a Cichlid and an Erythrinid fish of Southeastern Brazil

Two new species of Gyrodactylus Nordmann, 1832 (Platyhelminthes, Monogenoidea) are described from fishes collected from southeastern Brazil. Gyrodactylus geophagensis n. sp. was collected from the body surface of the "cará", Geophagus brasiliensis (Quoy and Gaimard, 1824) (Cichlidae), from the Rio da Guarda, state of Rio de Janeiro; its major diagnostic features are the morphology of the anchor with a short, truncate superficial root and the shape of the hooks - with a long, delicate shaft. Gyrodactylus trairae n. sp. parasitizes the body surface of the "traíra", Hoplias aff. malabaricus (Bloch, 1794) (Erythrinidae), from the rio Guandu, state of Rio de Janeiro and can be easily differentiated from other species of the genus by having a thin, dorsal bridge, connecting the superficial bar with the spathulated shield. These are the first species of Gyrodactylus formally reported from Brazil. Presently, 26 species of Gyrodactylidae are known from freshwater fishes in the neotropical region; a list of these species is provided.

Mothers' and Fathers' Early Relationship With Their Infant: Similar Yet Temporally Discordant Themes [La relation initiale des parents avec leur nourrisson: Thèmes similaires quoique temporellement discordants]

Objective: To examine first-time mothers' and fathers' themes in their relationship with their infant, how these themes change during the first four months postpartum, and similarities and differences in mothers' and fathers' themes. Participants: Eighteen first-time mother-father couples were separately interviewed at one; six and 16 weeks postpartum. Data Analysis: Audio-taped, transcribed interviews were analysed using a Grounded Theory approach. Results: Our findings reveal a common set of themes for mothers and fathers in relation to the infant : 1: Discovery, 2: Physical Proximity, 3: Emotional Closeness, 4: Initiation of Complementary Interactions and 5: Commitment to Love and Care. However, there was a striking lack of concordance between mothers and fathers for these themes at each point in time. Conclusions: Mothers' and fathers' experience of the early relationship with their infant is unique. Focussing on maternal as well as paternal ways of experiencing the early relationship with their infant sets the way to understanding early developing relationships in the family context.

Reducció de despeses ineficients i sostenibilitat de l'Estat del Benestar: el cas de Catalunya

Malgrat que el debat de l’Estat del Benestar està en el bell mig de l’actualitat política i econòmica des de fa uns quants anys amb graus ben diversos i aproximacions diferents, la darrera gran crisi ha disparat com mai la seva actualitat. Fins el present moment, amb algunes notables excepcions, totes les tendències han conduit a desenvolupar l’Estat del Benestar fins a extrems insostenibles. Això té explicacions múltiples i variades com les que s’aborden al llarg del present text. Aquestes tendències tenen una dinàmica econòmica i social pròpia que s’ha constatat amb força durant els darrers anys. Fa unes dues dècades que aquest debat va ser encetat amb profunditat per pocs països, però amb conclusions estimulants. Suècia és l’exemple més reeixit. La reforma duta a terme en el país nòrdics és una referència de primer ordre per molts estudiosos del tema i hauria de ser font d’inspiració per a la resta de països. Seguidament, hem volgut descriure, de forma complementària i des d’una perspectiva econòmica i jurídica, un fenomen estrictament lligat al desenvolupament imparable de l’Estat del Benestar, el de la burocratització. La reflexió d’acadèmics d’escoles en diferents i, en particular, els de la Public Choice proporcionen una visió rica i complexa, que entenem fonamental per avaluar els problemes que se’n deriven. Finalment, dins el marc de la Hisenda Pública i entrant en l’estudi concret del cas català, hem volgut endinsar-nos en l’anàlisi del pressupost. Essent com és una eina indispensable per avaluar el conjunt de polítiques econòmiques i socials d’un país. Aquesta anàlisi es duu a terme des d’una doble perspectiva: la primera, mitjançant un estudi comparatiu de l’evolució del Pressupost de la Generalitat dels darrers anys i, en segon terme, el canvi que el Pressupost 2011 materialitza aquest any, prefigura el de l’any 2012 i les principals crítiques de l’oposició. Queden oberts els camins envers els possibles canvis. De fet, res està definitivament escrit, però la pretensió d’aquest treball és modesta i, alhora, clara. Sense embuts, si volem mantenir un grau de benestar sostenible, és fonamental deixar de banda l’actual concepció de l’Estat del Benestar i començar a treballar per implementar els profunds canvis necessaris que donin pas a l’únic model que, a parer nostre, aconseguirà que això sigui possible: la Societat del Benestar. Una concepció actual del paper que ha de tenir l’Estat, de caràcter liberal i, alhora, social.

Teleost fish larvae adapt to dietary arachidonic acid supply through modulation of the expression of lipid metabolism and stress response genes

Dietary fatty acid supply can affect stress response in fish during early development. Although knowledge on the mechanisms involved in fatty acid regulation of stress tolerance is scarce, it has often been hypothesised that eicosanoid profiles can influence cortisol production. Genomic cortisol actions are mediated by cytosolic receptors which may respond to cellular fatty acid signalling. An experiment was designed to test the effects of feeding gilthead sea-bream larvae with four microdiets, containing graded arachidonic acid (ARA) levels (0·4, 0·8, 1·5 and 3·0 %), on the expression of genes involved in stress response (steroidogenic acute regulatory protein, glucocorticoid receptor and phosphoenolpyruvate carboxykinase), lipid and, particularly, eicosanoid metabolism (hormone-sensitive lipase, PPARα, phospholipase A2, cyclo-oxygenase-2 and 5-lipoxygenase), as determined by real-time quantitative PCR. Fish fatty acid phenotypes reflected dietary fatty acid profiles. Growth performance, survival after acute stress and similar whole-body basal cortisol levels suggested that sea-bream larvae could tolerate a wide range of dietary ARA levels. Transcription of all genes analysed was significantly reduced at dietary ARA levels above 0·4 %. Nonetheless, despite practical suppression of phospholipase A2 transcription, higher leukotriene B4 levels were detected in larvae fed 3·0 % ARA, whereas a similar trend was observed regarding PGE2 production. The present study demonstrates that adaptation to a wide range of dietary ARA levels in gilthead sea-bream larvae involves the modulation of the expression of genes related to eicosanoid synthesis, lipid metabolism and stress response. The roles of ARA, other polyunsaturates and eicosanoids as signals in this process are discussed.

A New Species of Kritskyia (Dactylogyridae, Ancyrocephalinae) Parasite of Urinary Bladder of Prochilodus lineatus (Prochilodontidae, Characiformes) from the Floodplain of the High Paraná River, Brazil

A new species of Kritskyia inhabits the urinary bladder of the "curimba", Prochilodus lineatus in the floodplain of the high Paraná river. The new species resembles others members of Kritskyia in the following features: haptor lacking anchors and with 14 hooks marginal, posterior male copulatory organ non articulated with the accessory piece and vagina a sclerotized tube. However, it differs from the known species mainly by the shape of the copulatory complex. This is the third endoparasitic monogenean species reported from freshwater Neotropical fish.

Neyraiella distinctus n. sp. (Oxyurida, Blattophilidae) Parasite of Nymphs of Gryllodes laplatae Sauss (Orthoptera, Gryllidae) in Argentina

Neyraiella distinctus n. sp. was found parasitizing nymphs of the cricket Gryllodes laplatae Sauss in City Bell, Argentina. This species was characterized by having the excretory pore in the posterior end of the basal bulb, vulva protruding with one lip well developed in the 1/3 end of the body, anus of the female with wings, male with a single spicule without any sculpture, gubernaculum and bursa are absent, six pairs of genital papillae arranged in two preanal pairs, one adanal pair and three postanal pairs, and the tail appendage in both sexes was short and conic.

Paralysie faciale: mise a jour pour le praticien [Facial palsy: update for the practitioner].

The clinical significance of facial palsy hinges on its psychosocial consequences. While its causes are very numerous, several infections account for a majority of cases: Lyme disease, geniculate zoster (Ramsay Hunt syndrome), while the role of HSV-1 in essential (Bell's) palsy remains controversial. Essentials of facial palsy management are discussed, including the importance of the functional grading of palsy, the complexity of Lyme disease serological diagnosis, and its treatment using doxycycline, antiviral and steroids treatment of geniculate zoster, while regarding essential facial palsy, only steroids, but not antiviral have been shown to improve functional recovery.

Malaise du nourrisson pensez à une intoxication à l'anis étoil [Apparent life-threatening event in infants: think about star anise intoxication!].

In previous years, several publications have reported cases of infants presenting neurological and gastrointestinal symptoms after ingestion of star anise tea. Such teas are sometimes given in various cultures for the treatment of infant colic pains. In most cases, the cause of intoxication was contamination of Chinese star anise (Illicium verum) by Japanese star anise (Illicium anisatum). Indeed, the toxicity of Illicium anisatum, also known as Shikimi, is caused by its content in potent neurotoxins (anisatin, neoanisatin, and pseudoanisatin), due to their activity as non-competitive antagonists of GABA receptors. The main reasons explaining the frequent contaminations are the strong macroscopic resemblance of the 2 substances, as well as the fact that the fruits are often sold partially broken or in ground form. Therefore, in most cases, chemical analysis is required to determine the possible adulterations. CASE REPORT: A 2-month-old infant, in good general health, was brought to the emergency unit after 3 consecutive episodes of central cyanosis and tetany of the limbs with spontaneous recovery the same afternoon. The child was also very irritable, regurgitated a lot, and positioned himself in opisthotonos. Between these episodes, the neurological exam showed some perturbations (horizontal nystagmus and Bell's phenomenon, hypertony of the extensor muscles, and mild hypotony of the axial flexor muscles) with slow improvement over the following hours. The remaining clinical exam, the laboratory work (complete blood count, renal, hepatic, and muscular tests, capillary blood gas, plasmatic amino acids, and urinary organic acids), and the electroencephalogram findings were all normal. In the course of a detailed interview, the parents reported having given 3 bottles to their child, each one containing 200 mL of an infusion with 4 to 5 fruits of star anise, in the hours preceding the symptoms to relieve colic pains. The last seizure-like event took place approximately 8h after the last ingestion. We could prove the ingestion of anisatin, the toxic substance found in Japanese star anise, and the contamination of Chinese star anise by the Japanese species. Indeed, the anisatin analysis by liquid chromatography and mass spectroscopy (LC-MS) in a urine sample taken 22 h after the last infusion ingestion showed trace amounts of the substance. In another urine sample taken 33 h after ingestion, no anisatin could be detected. Furthermore, the analysis of the fruit sample gave an anisatin concentration of 7800 μg/kg while the maximum tolerance value in Switzerland is 1000 μg/kg. CONCLUSION: The evaluation of ALTE in infants should always include the possibility of intoxication. Star anise is generally considered a harmless medicine. Nevertheless, it can sometimes cause a severe intoxication resulting in various neurological and gastrointestinal symptoms. To prevent such events, not only the parents, but also the care personnel and pharmacists must be informed about the possible adverse effects caused either by the overdose of Chinese star anise or by the eventual contamination of herbal teas with Japanese star anise. A better control of the substances by the health authorities is also necessary.
