Seven species of the genus Aulodrilus (Annelida, Clitellata, Tubificinae) are studied, based on new material from Japan. Aulodrilus dentosus sp. nov. is characterized as having tubular atrium, forked or bifid distal ends of dorsal crotchets, but no genital chaetae, and A. aestivus sp. nov. is characterized as having crescent-shaped atrium, median male bursa, and bifid chaetae in the dorsal bundles. Five other congeners are redescribed: A. limnobius Bretscher, A. pluriseta (Piguet), A. pigueti Kowalewski, A. japonicus Yamaguchi, and A. americanus Brinkhurst & Cook. Comparison of taxonomic characters among the 14 species recognized in the genus to date shows that three species differ from other congeners in several features: A. paucichaeta Brinkhurst & Barbour, A. adetus (du Bois-Reymond Marcus), and A. apeniatus Cui & Wang. They are provisionally maintained in the genus.

Abstract The article presents a morphemic account of transcategoriality, with detailed illustrations (e.g. English but and even, French encore, tout, meme, Latin to French morpheme /tant/) of the approach. After making explicit the paradigmatic differences between exoskeletal and endoskeletal approaches, and showing that ultimately it can be summarized in terms of existence or not of grammar-free morphemes becoming lexemes through grammatical and contextual insertion, it turns to the issue of knowing what an exoskeletal non-categorial meaning can be. It introduces at this stage the notion of fractality, before making explicit and detailing the method which allows isolation of a morpheme’s indicational semantics. The whole approach is finally illustrated with the study of the whole distribution of French /tant/, first semantically in synchrony before extending the tests to Latin data, showing that polysemy, transcategoriality and plurisemy are various forms of the same issue.

The spatial complexity of the distribution of organic matter, chemicals, nutrients, and pollutants has been demonstrated to have multifractal nature. This fact supports the possibility of existence of some emergent heterogeneity structure built under the evolution of the system. The aim of this paper is providing a consistent explanation of the mentioned results via an extremely simple model.

Ooplasm posses several, undefined factors allowing for reprogramming of somatic genome into pluripotent state. However, it is presently unknown if and to what extent the ooplasm is able to interact with a transferred somatic cell from another species in the context of interspecies somatic cell nuclear transfer (SCNT). The 1-cell stage embryos were processed at different time points (2, 4, 8, and 12 h post-activation) for detailed nuclear and nucleolar analysis by TEM, and immunofluorescence for visualisation of nucleolar proteins related to transcription (UBF) and processing (fibrillarin). The embryos produced by SCNT of porcine fibroblast into non-activated bovine ooplasm were compared to bovine parthenogenetic counterparts. In the absence of morphological remodelling features (premature chromatin condensation, nuclear envelope break-down), intergeneric embryos showed bovine nuclear and nucleolar precursor body (NPB) morphology. The somatic cell introduced into the bovine ooplasm displayed intranuclear activity at the post-translational level signalling a universal function of ooplasmic factors. The lack of distinct UBF localization in intergeneric embryos, however, suggests failures in sequence-specific interactions between the ooplasm and transferred cell from another genus. We conclude that sperm or a somatic cell of the same species is required for successful embryonic development.

Observations on the life cycles of aquatic oligochaetes were made in the period 1962–2017 at the Võrtsjärv Limnological Station (Estonia) using small aquaria with sieved profundal mud covered with unaerated water. The aquaria were mostly inseminated with 10 juvenile worms and checked four times a year, changing the mud and eliminating the progeny, until the natural death of the original worms. Besides, mass cultures were kept in bigger aquaria. Many individuals of Tubifex tubifex, T. newaensis, Limnodrilus hoffmeisteri, L. udekemianus, Ilyodrilus templetoni, Psammoryctides barbatus, Spirosperma ferox, Potamothrix moldaviensis, P. vejdovskyi, P. bavaricus, Stylodrilus heringianus and Rhynchelmis tetratheca survived for several years, reproduced repeatedly, and died out one by one during the observation period. In some cases, the most longevous individuals reached an age of up to 8 years (I. templetoni), 10–12 years (T. tubifex), 15–17 years (L. hoffmeisteri, P. barbatus, S. heringianus), or even more than 20 years (L. udekemianus, S. ferox, T. newaensis). Criodrilus lacuum did not reproduce in aquaria, although the oldest individual spent 46 years there. Potamothrix hammoniensis, Lophochaeta ignota, Lamprodrilus isoporus, most naidines and some others did not thrive in aquaria and usually died without reproducing. In a cellar, where temperature conditions imitated seasonal fluctuations in lakes, or when the aquaria were maintained at continuously low temperature, the lifetime of worms was often longer than at room temperature. At elevated temperatures (+25° to +35°C) T. tubifex and L. hoffmeisteri formed cocoons mostly with only 1–2 eggs while their life span was then shorter. Architomic clones of Potamothrix bedoti, Bothrioneurum vejdovskyanum, Aulodrilus pluriseta and A. japonicus survived and propagated for years. The architomic Lumbriculus variegatus was thriving only when fed, e.g., with yeast. Uniparental reproduction by parthenogenesis was observed in T. tubifex, L. hoffmeisteri and S. heringianus kept or reared single. Two special races(?) were noted both within T. tubifex and L. udekemianus.

The Upper Sakarya River System (USRS) is one of the most important river systems in Turkey. Its primary drainage is provided by the Porsuk Seydi and Bardakçı Rivers and their tributaries. Long term benthic invertebrate community structure in the USRS was investigated from 1995–2015 (with sampling conducted every five years) in order to assess changes in their composition and in relation to water quality. Oligochaete specimens sorted from samples were identified to the species level when possible; all other invertebrate specimens sorted from samples were identified to order and family level. In addition, some environmental parameters (e.g., dissolved oxygen, temperature, and hydrogen ion concentration as pH) were measured in situ. Although Ephemeroptera-Plecoptera-Trichoptera fauna were the most abundant group in fauna of USRS during the years 1995, 2000 and (in part) 2005 (18.80, 17.69, and 14.07%, respectively), this ratio decreased to 7.90% during the more recent years of monitoring. In 1995, 2000 and 2005, Nais bretscheri, Chaetogaster diastrophus, Chaetogaster langi, Pristinella jenkinae, Aulodrilus pigueti, Aulodrilus pluriseta, Potamothrix hammoniensis, and Psammoryctides albicola were the dominant oligochaete taxa. After 2005, tubificine species became more prevalent in samples. While 6 stations had high BMWP (Biological Monitoring Working Party) value in 1995, 2000 and 2005, only 1 station had high value after 2005. Values of Shannon Diversity Indices ranged from 2.00 to 3.05 for the years 1995–2000, 1.87 to 2.24 for the years 2000–2005, 1.06 to 1.85 for the years 2005–2010, and 0.97 to 1.80 for the years 2010–2015. In USRS, while values of dissolved oxygen were measured as 8.00 mg/l and 9.00 mg/l in 1995 and 2000, this high value was measured only at one station in 2015. It was found that numerical and proportional distributions of benthic invertebrates in the USRS have changed considerably between 1995 and 2015. It is obvious that these changes are the result of anthropogenic habitat degradation.

Both preimplantation and full-term development of mouse somatic cell nuclear transfer (SCNT) embryos are significantly enhanced by treatment with trichostatin A (TSA), an inhibitor of histone deacetylase (Kishigami et al. 2006 Biochem. Biophys. Res. Commun. 340, 183–189; Rybouchkin et al. 2006 Biol. Reprod. 74, 1083–1089). The present study was designed to examine the effect of TSA treatment on preimplantation and full-term development of bovine cloned embryos. To investigate the effect of TSA on bovine NT embryos development, we treated them with 50 nM TSA during the first 10 h after activation. Bovine NT-embryos were reconstructed using adult fibroblasts of 2 female donors (A and B) with significantly different in vitro cloning efficiency (respectively, 84/245; 34.3% v. 155/298; 52.1% blastocyst D7, P ≤ 0.05, chi-square test). TSA treatment significantly improved blastocyst rate in A, however did not affect development in B (56.3% and 50.5%, respectively). The level of acetylated histone H3K9 10 h after activation detected by anti-acH3K9 antibody was significantly increased after TSA-treatment in A (P ≤ 0.05, Student’s t-test) but did not change in B, thus demonstrating that the levels of histone acetylation in cloned embryos correlate with their in vitro developmental potential. To evaluate the long-lasting effect of TSA-treatment on the full-term development of cloned embryos, SCNT embryos derived from 4 female donor animals were reconstructed. 196 TSA-treated embryos at the blastocyst stage were transferred into 98 recipients and 2 calves (2%) were born. In the control group, 167 embryos were transferred into 141 recipients and 3 calves (2.1%) were born. Our data show that cell lines demonstrate different susceptibility to TSA that may affect reprogramming of the somatic genome with low level of acetylation resulting in higher in vitro embryo development. However, TSA does not improve overall cloning efficiency in cattle, measured as full-term development.

A dissertação Flavio-Shiró, sua Pintura e sua Plurisensorialidade, tem como objetivo estudar algumas obras criadas pelo artista nas décadas de 1950, 1960 e 1970 e que se destacaram pelo uso diversificado de materiais. A materialidade e a maneira de pintar fazem referências aos gestos caligráficos orientais gestos estes que norteiam todo o seu percurso artístico. A materialidade foi aqui analisada como uma maneira de destacar as relações do material com a técnica utilizada pelo artista tanto na fabricação quanto na manipulação de sua obra de arte. A fotografia de Flavio-Shiró foi outra técnica estudada, na presente pesquisa, porém dentro de uma análise comparativa com algumas de suas pinturas. É uma técnica utilizada pelo artista que requer maior detalhe na pesquisa. Por isso, há uma intenção de continuar com os estudos fotográficos, pois as fotografias de Flavio-Shiró levantam discussões sobre uma época da fotografia abstrata e seus experimentos. Quanto à performance nas obras de Flavio-Shiró aparecem novas discussões sobre a pintura do artista. Buscam-se pontos de convergências com artistas que trabalharam de maneira performática como: Jackson Pollock e Antoni Tàpies, estabelecendo paralelos com a performance na pintura oriental. As linhas são formadas a partir de gestos em uma posição não tão habitual para um artista, ou seja, agachando-se sobre a obra, revelando destreza na formação de linhas firmes e ágeis, mesmo que não haja a formação dos ideogramas, reminiscências de um passado que se faz presente em sua vida. Devido a isso, na produção pictórica, o artista (de maneira performática na horizontal ou na vertical, dependendo da intencionalidade e da matéria que utiliza) transforma a pincelada, em um gesto vigoroso e expressivo. Percebe-se que há uma energia física e corporal que formam, a cada pincelada, desenhos e ideogramas que expressam a essência da escrita. Por isso, esta pesquisa, procura estabelecer um possível diálogo entre a arte milenar da caligrafia japonesa e a expressividade de caráter performático na pintura de Flavio-Shiró. A ânsia por liberdade na pintura de Shiró vem desde a sua infância, quando ele ainda recebia incentivo do pai, e até hoje o torna um pintor com características tão ímpares de produção artística. E a sua preocupação com relação à vida e ao cotidiano, pelo fato de ser um artista que nunca se preocupou em se especializar em um movimento ou técnica de pintura é o que o alimenta durante seu percurso performático.

Ce travail s'attache à la construction textuelle du brevet d'invention (type de texte spécialisé très normé) par l'étude des contraintes pragmatiques le structurant et notamment celles le définissant comme une contribution au sens gricéen (Grice), post-gricéen (Nemo, Portuguès) ou non-gricéen (Clark et Schaefer). Il étudie ses stratégies textuelles, par exemple en termes de rhétorique de la revendication, en se penchant sur son format particulier dans lequel sont isolés des éléments récurrents et autonomes, les ensembles contributionnels, et leurs liaisons.La première partie présente l'approche contributionnelle du texte de brevet d'invention. Il s'agit d'une part de décrire le texte comme un objet contributionnel, et d'autre part de se demander dans quelle mesure la confrontation avec un texte hyperformaté conduit à reconsidérer les maximes (gricéennes) régulant les contributions. Le corpus d'étude est constitué d'une base textuelle de brevets d'invention transformée en base de données contributionnelles. L'analyse de celle-ci permet une modélisation contributionnelle du texte de brevet fondée sur des marqueurs délimitant des ensembles contributionnels soumis à un schéma général invariant, prédictible et reproductible. La phase de modélisation est l'occasion de reformuler une partie des maximes gricéennes encadrant la production d'ensembles contributionnels. Dans le cadre d'une conception plurisémique de l'interprétation, la fin de l'étude dégage les propriétés de la strate contributionnelle, en montrant notamment qu'à partir de la contrainte de complétude du texte en train de se construire et au travers des différentes sous-contributions qui le constituent se met en place une mécanique textuelle reposant sur des enchaînements contributionnels spécifiques aux textes formatés. Ces considérations sur la matière contributionnelle des textes permettent d'aborder les fondements d'une théorie contributionnelle du texte.
