Preliminary results of venlafaxine exposure in pregnancy, a multicenter prospective cohort ENTIS study

Introduction: Venlafaxine (Efexor®) is a serotonin and noradrenaline reuptake inhibitor (SNRI) used for the treatment of depression and anxiety disorders. The limited data on the use of venlafaxine in human pregnancy do not indicate an increased risk of congenital malformations. The main purpose of the study is to assess the rate of major malformations after first trimester exposure to venlafaxine. Methods: This multicenter, prospective cohort study was performed using data from nine centers who are member of the European Network of Teratology Information Services (ENTIS). Data on pregnancy and pregnancy outcome of women who used venlafaxine in pregnancy were collected during individual risk counseling. Standardized procedures for data collection and followup were used by each center. Results: Follow up data were collected on 744 pregnancies of womenwhoused venlafaxine during gestation. In 583 (78.4%) cases the exposure had occurred at least in the first trimester. In total, there were 600 live births (5 twins), 85 spontaneous abortions, 57 elective terminations of pregnancy, 5 fetal deaths, and 2 ectopic pregnancies. The overall rate of major malformations after first trimester exposure and excluding chromosomal and genetic disorders was 3.2% (16/500) in all pregnancies ending in delivery, pregnancy terminations or fetal deaths with fetal-pathological examination. Among live births the malformation rate was 2.7% (13/490). We observed no increased risk for organ specific malformations. Conclusions: The present study indicates that venlafaxine is not a major human teratogen.

Некоторые наблюдения по поводу построения компьютерного морфологического анализатора марийского языка. [Problems in writing a two-level model of Mari morphology]

The article describes some concrete problems that were encountered when writing a two-level model of Mari morphology. Mari is an agglutinative Finno-Ugric language spoken in Russia by about 600 000 people. The work was begun in the 1980s on the basis of K. Koskenniemi’s Two-Level Morphology (1983), but in the latest stage R. Beesley’s and L. Karttunen’s Finite State Morphology (2003) was used. Many of the problems described in the article concern the inexplicitness of the rules in Mari grammars and the lack of information about the exact distribution of some suffixes, e.g. enclitics. The Mari grammars usually give complete paradigms for a few unproblematic verb stems, whereas the difficult or unclear forms of certain verbs are only superficially discussed. Another example of phenomena that are poorly described in grammars is the way suffixes with an initial sibilant combine to stems ending in a sibilant. The help of informants and searches from electronic corpora were used to overcome such difficulties in the development of the two-level model of Mari. The variation of the order of plural markers, case suffixes and possessive suffixes is a typical feature of Mari. The morphotactic rules constructed for Mari declensional forms tend to be recursive and their productivity must be limited by some technical device, such as filters. In the present model, certain plural markers were treated like nouns. The positional and functional versatility of the possessive suffixes can be regarded as the most challenging phenomenon in attempts to formalize the Mari morphology. Cyrillic orthography, which was used in the model, also caused problems. For instance, a Cyrillic letter may represent a sequence of two sounds, the first being part of the word stem while the other belongs to a suffix. In some cases, letters for voiced consonants are also generalized to represent voiceless consonants. Such orthographical conventions distance a morphological model based on orthography from the actual (morpho)phonological processes in the language.

Natural Science in the Bothnian Sea During 1975-2008: A Review

The Baltic Sea is one of the most studied areas in the world. However, parts of its northernmost reach, the Bothnian Sea, seem to be under represented in the natural scientific literature compared to other parts of the Baltic. The Bothnian Sea represents a unique inland sea environment for the scientific community to study due to its shallowness and low salinity. The natural sciences research carried out on the Bothnian Sea has been reviewed between 1975 and 2008. This time period was chosen to continue on from an earlier review paper ending in 1974. Along with the number of papers published the goal was also to review the content of the papers, indentifying dominating themes to evaluate gaps in the current knowledge on the Bothnian Sea and provide recommendations for topics of future research focus. In a classification into specific research topics biodiversity was the leading research focus followed by chemical and physical oceanography, pollution and toxins, and fish biology and fisheries. The current good condition of the Bothnian Sea is highly valued with its historically less eutrophic and clearer waters when compared to the Baltic. However, today the Bothnian Sea is facing eutrophication resulting from nutrient-rich water transported by the many rivers draining into it from Sweden and Finland making it an area in need of protection and preservation. More human activity will also concentrate on the Bothnian Sea in the future. Therefore the use of the sea and its coastal areas must be planned carefully to minimize the harmful effects of this increasing human activity. To achieve this more information is needed for the basis of Integrated Coastal Zone Management (ICZM) and maritime spatial planning (MSP). For example, for the Bothnian Sea the information on the underwater nature which is essential for ICZM is so far missing to a large extent. Specific biological, chemical and physical oceanographic information is needed to combine with economic analyses and environmental policies regarding this region. More research of a multidisciplinary nature is required on the unique Bothnian Sea environment and this we feel is best achieved through a joint Finnish-Swedish research strategy.

The Place of the Gods : Biblical, Tragic, and Humanist Modes in Shakespeare’s Antony and Cleopatra

Ce mémoire se focalise sur la pièce Antony and Cleopatra de Shakespeare en relation avec la pensée biblique, l’humanisme de la Renaissance et les caractéristiques de la tragédie comme genre littéraire et philosophie grecque. La chute d’Adam et Eve dans la Bible, ainsi que le conflit entre le héros tragique et les dieux, sont deux thèmes qui sont au centre de ce mémoire. Le mythe de la chute d’Adam et Eve sert, en effet, d’un modèle de la chute—et par conséquent, de la tragédie—d’Antoine et Cléopâtre mais aussi de structure pour ce mémoire. Si le premier chapitre parle de paradis, le deuxième évoque le péché originel. Le troisième, quant à lui, aborde une contre-rédemption. Le premier chapitre réfère à l’idée du paradis, ou l’Éden dans la bible, afin d’examiner ce qui est édénique dans Antony and Cleopatra. La fertilité, l’épicuréisme, l’excès dionysien sont tous des éléments qui sont présents dans la conception d’un Éden biblique et Shakespearien. Le deuxième chapitre est une étude sur la tragédie comme genre fondamentalement lié à la pensée religieuse et philosophique des grecs, une pensée qui anime aussi Antony and Cleopatra. Ce chapitre montre, en effet, que les deux protagonistes Shakespeariens, comme les héros tragiques grecs, défient les dieux et le destin, engendrant ainsi leur tragédie (ou ‘chute’, pour continuer avec le mythe d’Adam et Eve). Si le deuxième chapitre cherche à créer des ponts entre la tragédie grecque et la tragédie Shakespearienne, le troisième chapitre montre que le dénouement dans Antony and Cleopatra est bien différent des dénouements dans les tragédies de Sophocle, Euripide, et Eschyle. Examinant la pensée de la Renaissance, surtout la notion d’humanisme, la partie finale du mémoire présente les protagonistes de Shakespeare comme des éternels rebelles, des humanistes déterminés à défier les forces du destin.

Modeling premartensitic effects in Ni2MnGa: A mean-field and Monte Carlo simulation study

ic first-order transition line ending in a critical point. This critical point is responsible for the existence of large premartensitic fluctuations which manifest as broad peaks in the specific heat, not always associated with a true phase transition. The main conclusion is that premartensitic effects result from the interplay between the softness of the anomalous phonon driving the modulation and the magnetoelastic coupling. In particular, the premartensitic transition occurs when such coupling is strong enough to freeze the involved mode phonon. The implication of the results in relation to the available experimental data is discussed.

Symmetry in biology: from genetic code to stochastic gene regulation

Mathematical models, as instruments for understanding the workings of nature, are a traditional tool of physics, but they also play an ever increasing role in biology - in the description of fundamental processes as well as that of complex systems. In this review, the authors discuss two examples of the application of group theoretical methods, which constitute the mathematical discipline for a quantitative description of the idea of symmetry, to genetics. The first one appears, in the form of a pseudo-orthogonal (Lorentz like) symmetry, in the stochastic modelling of what may be regarded as the simplest possible example of a genetic network and, hopefully, a building block for more complicated ones: a single self-interacting or externally regulated gene with only two possible states: ` on` and ` off`. The second is the algebraic approach to the evolution of the genetic code, according to which the current code results from a dynamical symmetry breaking process, starting out from an initial state of complete symmetry and ending in the presently observed final state of low symmetry. In both cases, symmetry plays a decisive role: in the first, it is a characteristic feature of the dynamics of the gene switch and its decay to equilibrium, whereas in the second, it provides the guidelines for the evolution of the coding rules.

The functions of Japanese Sound Symbolic Words in Different Types of Texts and Their Translation

Though sound symbolic words (onomatopoeia and mimetic words, or giongo and gitaigo in Japanese) exist in other languages, it would not be so easy to compare them to those in Japanese. This is because unlike in Japanese, in many other languages (here we see English and Spanish) sound symbolic words do not have distinctive forms that separate them immediately from the rest of categories of words. In Japanese, a sound symbolic word has a radical (that is based on the elaborated Japanese sound symbolic system), and often a suffix that shows subtle nuance. Together they give the word a distinctive form that differentiates it from other categories of words, though its grammatical functions could vary, especially in the case of mimetic words (gitaigo). Without such an obvious feature, in other languages, it would not be always easy to separate sound symbolic words from the rest. These expressions are extremely common and used in almost all types of text in Japanese, but their elaborated sound symbolic system and possibly their various grammatical functions are making giongo and gitaigo one of the most difficult challenges for the foreign students and translators. Studying the translation of these expressions into other languages might give some indication related to the comparison of Japanese sound symbolic words and those in other languages. Though sound symbolic words are present in many types of texts in Japanese, their functions in traditional forms of text (letters only) and manga (Japanese comics)are different and they should be treated separately. For example, in traditional types of text such as novels, the vast majority of the sound symbolic words used are mimetic words (gitaigo) and most of them are used as adverbs, whereas in manga, the majority of the sound symbolic words used (excluding those appear within the speech bubbles) are onomatopoeias (giongo) and often used on their own (i.e. not as a part of a sentence). Naturally, the techniques used to translate these expressions in the above two types of documents differ greatly. The presentation will focus on i) grammatical functions of Japanese sound symbolic words in traditional types of texts (novels/poems) and in manga works, and ii) whether their features and functions are maintained (i.e. whether they are translated as sound symbolic words) when translated into other languages (English and Spanish). The latter point should be related to a comparison of sound symbolic words in Japanese and other languages, which will be also discussed.

3 CHAMAEZA ANTTHRUSHES IN EASTERN BRAZIL (FORMICARIIDAE)

There are three, not two, sibling antthrushes of the genus Chamaeza (Formicariidae) in eastern Brazil. One is the short-tailed, large, pale-billed, lower montane C. campanisona, with a spotted throat, dark forehead, and a long song ending in several grunts. The second is the long-tailed, small, dark-billed, montane and southern C. ruficauda, with barred undertail coverts and a short upscale song. The third is medium-tailed, small, dark-billed, midmontane, with a long upscale song like that of midmontane so-called ruficauda in Colombia and Venezuela. This northern group is like the third Brazilian species in proportions but not in coloration, so is considered to be the separate species C. turdia. The third Brazilian bird is probably C. meruloides Vigors 1825, based on an 1826 color plate; type specimens were sold at auction and have disappeared. It has a reddish crown and olive-brown back as in C. campanisona but reddish forehead and tail as in C. ruficauda; the throat is unspotted but the rest of the underparts are as in C. campanisona. C. meruloides and C. turdina form a vocally similar superspecies.

Study of the venom glands in Ectatomma quadridens (Hymenoptera: Formicidae). Evolutionary hypothesis in subfamily ponerinae

The venom glands of worker ants of the species Ectatomma quadridens morphologically resemble an elongated sac or reservoir ending in a narrower portion that has the function of releasing the secretion to the exterior. Two external secretory filaments are individually inserted into the proximal portion of the gland and end inside the convoluted gland. The venom gland of workers of E. quadridens is, therefore, morphologically subdivided into four distinct portions: a) sac-shaped reservoir measuring approximately 1mm in length; b) excretory duct, proximal portion of the reservoir that joins the gland to the sting apparatus; c) convoluted gland, final portion of the external secretory filaments located inside the reservoir; and d) two secretory filaments measuring about 2 mm in length; their free extremities end blindly and are individually inserted into the reservoir wall at the proximal region of the venom gland. The histological data showed that the filaments and the convoluted gland are composed of cubic cells of secretory function. The reservoir consists of a simple cubical epithelium externally surrounded by muscle fibers. A thick cuticle internally coats the epithelium of the reservoir. The application of histochemical tests allowed us to establish that the final secretion of the venom gland of Ectatomma quadridens is of glycoproteic nature. This secretion undergoes several modifications at the secretory filaments, at the convoluted gland, and in the reservoir before reaching the excretory duct, the point at which the secretion is released in its final composition, namely the venom. Based on the differences among various Ponerinae species we propose a hypothesis suggesting a probable evolutionary process that the venom glands of members of this subfamily might have undergone.

Application of molecular markers on genetic improvement and reproduction in the post-genomic Era: Emerging biotechnologies and perspectives in livestock

Background: New challenges are rising in the animal protein market, and one of the main world challenges is to produce more in shorter time, with better quality and in a sustainable way. Brazil is the largest beef exporter in volume hence the factors affecting the beef meat chain are of major concern in countrýs economy. An emerging class of biotechnological approaches, the molecular markers, is bringing new perspectives to face these challenges, particularly after the publication of the first complete livestock genome (bovine), which has triggered a massive initiative to put in practice the benefits of the so called the Post-Genomic Era. Review: This article aimed at showing the directions and insights in the application of molecular markers on livestock genetic improvement and reproduction as well at organizing the progress so far, pointing some perspectives of these emerging technologies in Brazilian ruminant production context. An overview on the nature of the main molecular markers explored in ruminant production is provided, which describes the molecular bases and detection approaches available for microsatellites (STR) and single nucleotide polymorphisms (SNP). A topic is dedicated to review the history of association studies between markers and important trait variation in livestock, showing the timeline starting on quantitative trait loci (QTL) identification using STR markers and ending in high resolution SNP panels to proceed whole genome scans for phenotype/genotype association. Also the article organizes this information to reveal how QTL prospection using STR could open ground to the feasibility of marker-assisted selection and why this approach is quickly being replaced by studies involving the application of genome-wide association using SNP research in a new concept called genomic selection. Conclusion: The world's scientific community is dedicating effort and resources to apply SNP information in livestock selection through the development of high density panels for genomic association studies, connecting molecular genetic data with phenotypes of economic interest. Once generated, this information can be used to take decisions in genetic improvement programs by selecting animals with the assistance of molecular markers.

Macroscopic and Microscopic findings in a set of congenital anomalies in two calves produced through in Vitro production

In vitro production and somatic cell nuclear transfer are biotechnologies widely used for breeding cattle, although may result in congenital anomalies. This paper aims to report a set of congenital anomalies in two Nelore calves, a male and a female, produced through in vitro fertilization. The major anomalies revealed at necropsy were hypospadias, bifid scrotum, atresia ani and rectum ending in blind pouch in the male calf. In the female calf accessory spleen, atresia ani, underdevelopment of extern genitalia and urethral orifice, and rectum ending in blind pouch forming a uterus-rectum fistula were observed.

La comunicazione chimica in Blattaria: contributo al miglioramento della lotta

CHEMICAL COMMUNICATION IN BLATTARIA: CONTRIBUTION TO THE IMPROVEMENT OF THE CONTROL TECNIQUES The management of cockroach infestations in urban environment has undergone some changes in recent years by moving to the predominant use of baits, thanks to the awareness of the risks connected with the use of spray insecticides. The effectiveness of a bait is determined by the collective performance of its components, including active and inert ingredients, the food attractant and any other attractive odour. This research has focused on the behavioral responses of Italian sinanthropic cockroaches to semiochemicals and food attractants, for the purpose of evaluating a possible practical application and of contributing to the improvement of control techniques. Behavioral and morphological studies have been carried out on Supella longipalpa (F.), a small cockroach that is spreading in Italy. Behavioral assays showed that the fourth and fifth tergites of females are significantly more attractive than other region of the body. Cuticular pores and ducts ending in glandular structures (observed with a S.E.M. = Scanning Electron Microscope) are present in large number on these tergites, suggesting that they could be involved in the production and the release of sexual pheromone. Cockroaches produce an aggregation pheromone that is excreted along with their frass and that consists of volatile and non-volatile compounds, mainly amines and steroidal glycosides. The effectiveness of faecal extracts obtained from excrements of Blattella germanica (L.), Blatta orientalis L., Periplaneta americana (L.) and S. longipalpa was evaluated, both at intraspecific and interspecific level, using a "Y" tube olfactometer. Bioassays showed that faecal extracts obtained with methanol have a good intraspecific attractiveness and, in some cases, they showed also interspecific behavioral responses. A gel was prepared, having physical characteristics that could give a good resistance to dehydration, as a potential basis for a new bait; the gel was then added faecal extracts, obtained with methanol from B. germanica and S. longipalpa frass. Arena-tests showed that the new gel containing faecal extracts is more attractive than some commercial gel formulations used as comparison: it was the only product that could attract 100% of insects placed in the arenas in 4-5 days. In conclusion, the substances involved in chemical communication of Blattaria may be able to effectively increase the attractiveness of products for monitoring and controlling cockroaches.

La concezione epistemica dell'analiticità: un dibattito in corso

Il lavoro è una riflessione sugli sviluppi della nozione di definizione nel recente dibattito sull'analiticità. La rinascita di questa discussione, dopo le critiche di Quine e un conseguente primo abbandono della concezione convenzionalista carnapiana ha come conseguenza una nuova concezione epistemica dell'analiticità. Nella maggior parte dei casi le nuove teorie epistemiche, tra le quali quelle di Bob Hale e Crispin Wright (Implicit Definition and the A priori, 2001) e Paul Boghossian (Analyticity, 1997; Epistemic analyticity, a defence, 2002, Blind reasoning, 2003, Is Meaning Normative ?, 2005) presentano il comune carattere di intendere la conoscenza a priori nella forma di una definizione implicita (Paul Horwich, Stipulation, Meaning, and Apriority, 2001). Ma una seconda linea di obiezioni facenti capo dapprima a Horwich, e in seguito agli stessi Hale e Wright, mettono in evidenza rispettivamente due difficoltà per la definizione corrispondenti alle questioni dell'arroganza epistemica e dell'accettazione (o della stipulazione) di una definizione implicita. Da questo presupposto nascono diversi tentativi di risposta. Da un lato, una concezione della definizione, nella teoria di Hale e Wright, secondo la quale essa appare come un principio di astrazione, dall'altro una nozione della definizione come definizione implicita, che si richiama alla concezione di P. Boghossian. In quest'ultima, la definizione implicita è data nella forma di un condizionale linguistico (EA, 2002; BR, 2003), ottenuto mediante una fattorizzazione della teoria costruita sul modello carnapiano per i termini teorici delle teorie empiriche. Un'analisi attenta del lavoro di Rudolf Carnap (Philosophical foundations of Physics, 1966), mostra che la strategia di scomposizione rappresenta una strada possibile per una nozione di analiticità adeguata ai termini teorici. La strategia carnapiana si colloca, infatti, nell'ambito di un tentativo di elaborazione di una nozione di analiticità che tiene conto degli aspetti induttivi delle teorie empiriche

[Case report: an exceptional case of a monozygotic thoracopagus parasiticus in a German Holstein calf]

A black and white German Holstein calf displayed a complex double malformation in shape of a thoracopagus parasiticus. By means of a molecular genetic investigation the genesis of the malformation from one zygote could be demonstrated. Both vertebral columns showed a pronounced lordosis, with the vertebral column of one animal ending in a rudimentary head. Close to this rudiment two derivates of branchial arches were found. The two thoracic cavities merged into one "thorax". In the shared thoracic cavity one heart was found. In its right atrium, a cherry-sized structure was found in which heart- and vascular smooth muscles were demonstrated histologically. The aorta split shortly after its origin to provide both animals with one aorta each. The larger pair of lungs was connected with a trachea leading to the head while the smaller pair of lungs originated from a trachea deriving from the rudimentary head. The diaphragm jejunum and split afterwards. The pedigree of the affected animal showed neither inbreeding nor any other affected animal.
