Formação do plexo braquial e sistematização dos territórios nervosos em membros torácicos de lobos-marinhos Arctocephalus australis

For the study concerning the brachial plexus (BP) and the nervous territories of the thoracic limb of South American Fur Seal (Arctocephalus australis), two animals had been used. Their skin was removed and the musculature of the thoracic limb and pectoral region was identified. After that compresses of glacial acetic acid solution of 3% had been applied in the musculature, in order to facilitate the carried through dissection. In analyzed specimens it was observed the emergency of BP from the sixth cervical nerve until the first thoracic nerve. From these four roots trunks of nerves of the same number are formed, whose ventral branches will constitute its arrangement and territorial distribution. From these four trunks emerge the 12 component nerves of the BP, some of them come from only one segment (supra scapular, cranial pectoral, lateral thoracic, thoraco-dorsal and long thoracic), while others come from more than a segment (sub scapular, muscle-cutaneous, axillary, median, caudal pectoral, ulnar and radial). In this direction,this observed constancy in the innervation of the musculature, joints and bones of the thoracic limb, led us to infer that a definite pattern in the delimitation of the nervous territories clearly exists.

ADVANCEMENT OF NUCLEIC ACID-BASED TOOLS FOR MONITORING IN SITU REDUCTIVE DECHLORINATION

Regulatory protocols generally recognize that destructive processes are the most effective mechanisms that support natural attenuation of chlorinated solvents. In many cases, these destructive processes will be biological processes and, for chlorinated compounds, will often be reductive processes that occur under anaerobic conditions. The existing EPA guidance (EPA, 1998) provides a list of parameters that provide indirect evidence of reductive dechlorination processes. In an effort to gather direct evidence of these processes, scientists have identified key microorganisms and are currently developing tools to measure the abundance and activity of these organisms in subsurface systems. Drs. Edwards and Luffler are two recognized leaders in this field. The research described herein continues their development efforts to provide a suite of tools to enable direct measures of biological processes related to the reductive dechlorination of TCE and PCE. This study investigated the strengths and weaknesses of the 16S rRNA gene-based approach to characterizing the natural attenuation capabilities in samples. The results suggested that an approach based solely on 16S rRNA may not provide sufficient information to document the natural attenuation capabilities in a system because it does not distinguish between strains of organisms that have different biodegradation capabilities. The results of the investigationsmore » provided evidence that tools focusing on relevant enzymes for functionally desired characteristics may be useful adjuncts to the 16SrRNA methods. « less
Giemsa C-banded karyotypes of South and Central American Hordeum (Poaceae). II. 6 polyploid taxa.

The chromosomes of the six South and Central American polyploid Hordeum species, H. procerum (6x). H. lechleri (6x). H. tetraploidum (4x), H. fuegianum (4x). H. parodii (6x), and H. guatemalense (4x). had similar C-banding patterns with normally between two and 12 very small or small bands per chromosome at no preferential positions. Marker chromosome morphology suggested that all taxa contain two genomes similar to those of H. juhatum and H. hrachyantherum (4x); however, in H. tetraploidum. H. fuegianum. and H. parodii they are modified through introgression from H. patagonicum (2x). The karyotypes of the two latter tetraploids are considered homologous although H. fuegianum has an extra SAT-chromosome pair. H. prucerum and H. lechleri are proposed to combine the genomes of H. jubatum or H. brachyan-therum (4x) and the South American H. cordohense (2x) and an unidentified South American diploid Hordeum species, respectively; and H. parodii, the genomes of H. tetraploidum and the South American H. muticum (2x). The karyotype common to H. juhatum, H. brachyantherum (4x). and H. guatemalense is suggested to comprise the genome of the Asian H. roshevitzii (2x) besides that of the North American H. brachyantherum (2x). The proposed origin of the polyploid species indicates that it is hardly biologically relevant to refer them to separate taxonomic sections. One population of H. procerum had a SAT-chromosome pair with active nucleolar constrictions in both arms.
In Between Military and Militia: The Dynamics of the Security Forces in Communal Conflict in Ambon

This article presents and discusses the role of the security forces in the communal conflict in Ambon, Indonesia. Though it shares the view articulated by many scholars and social obervers that the security forces played partisan roles in prolonging the Ambon conflict, it criticizes the tendency to overstate their role and see them as a single homogenous actor. Based on extensive research and fieldwork, this paper argues that the dynamics of the role of the security forces in the conflict in Ambon evolved in concert with the dynamics of the conflict itself and was influenced by both local and national factors and their respective actors. It also examines the issue in the context of civil-military relations in the aftermath of the collapse of the authoritarian regime, with particular attention paid to its impact on security sector reform.
Estimation of Heterosis , Combining Ability , Gene Action , Genotypic and Phenotypic Correlation in Peas (Pisum sativum L.)

The experiment was carried out in the Field of the Horticulture andLandscape Design Department, College of Agriculture and Forestry, Mosul University , during the 2009/2010 and 2010/2011 growing seasons, The aim was to evaluate performance of hybrids and their parents to identif promising hybrids and to estimate heterosis, combining ability, heritability, expected genetic advance, phenotypic and genotypic correlation and gene action and their effects on the inheritance of the studied characters. The method was the complete Full- Diallel Crosses using four varieties of Peas (Pisum sativum L.) viz, (Carina , English , Green Feast and Little Marvel ) using Randomized Complete Block Design (R.C.B.D) with three replications. The results indicated that general combining ability was significant for all the studied characters except for number of seeds/pod and biological yield, and that specific combining ability and reciprocal effects was significant for most studied characters. Results showed that parents and F1s were significantly different for all studied characters. The hybrid 3x4 has significantly higher heterosis values that the other hybrids for yield related characters with significant specific combining ability for the most desirable characters. This could be , due to the wide genetic diversity between its parents. Little Marvel variety showed high and significant general combining ability for most of the studied characters, and therefore contains the desired gene. Significant additive variance were found for all studied characters except for plant height, number of seeds/pod and biological yield. Narrow sense heritability was high for: maturity date, average seed weight , pod length, 100 seed weight and green pods yield, which indicated the presence of additive gene action controlling these characters. Over dominance were found for most studied characters. The higher phenotypic correlation was found between green and dry pods yield, and higher genotypic correlation was found between dry pods yield and seeds yield.
Knowledge, Attitude and Practices Among Nurses Towards Newborn Hearing Screening in India

Background and objectives: Multidisciplinary team approach can act as the major facilitator for the successful implementation of newborn hearing screening. Nurses can act as a good educator for the parents due to their close association. Therefore, the need was felt to explore the knowledge, attitudes and existing practices towards newborn hearing screening. Method: Cross-sectional study was carried out using the convenient sampling in a tertiary hospital to assess knowledge, attitude and practices. Results: The familiarity about newborn hearing screening was relatively low, also there was lack of surety regarding the ideal time for receiving additional testing for the newborns not passing the screening. More than 90% were positive about screening all newborns for hearing loss at the same time 40% felt that it leads to excessive anxiety and concerns. Conclusion: The role played by nurses include educating parents, explaining parents about impact of hearing loss, follow-up and facilitator for screening process as team member. Nurses showed positive attitude while at the same time emphasized need to have additional information

Key to Acanthocephala Reported in Waterfowl.

Abstract : This is the third part of a continuing series on helminths reported in waterfowl (McDonald 1974, 1981). Coots and moorhens (in Family Rallidae, Order Gruiformes) are included with the Anatidae of Anseriformes. The goal of these studies is complete coverage of waterfowl helminths of the world, although the original incentive-inadequate knowledge of the parasites of North American waterfowl-is less true now. World coverage is desirable because the world distribution of the family, tribes, and even many species of waterfowl often results in world distribution of parasites. The format of this key follows that of the others in the series: a checklist of species, a general key to families and genera, a guide to identification of species, and keys to species of each genus that has more than one species reported in waterfowl. This group is the smallest of the series, with 52 species, of which 11 may be considered accidental, normally belonging in birds of other orders (two also normally mature only in marine mammals-although recorded in many birds-and one in freshwater rodents). One species is reported only from domestic waterfowl and one only experimentally from domestic ducklings, whereas six other species have been reported from both wild and domestic waterfowl. The frequency of occurrence and status of hosts in the checklist have been based on the literature. All Acanthocephala in waterfowl are found in the small intestine (usually in the posterior portion) and the large intestine.
Effect of different herbicides on mixed weed flora, yield and economics of wheat (Triticum aestivum) under irrigated conditions of Jammu

A field experiment was conducted during the winter (rabi) season of 2004-05 and 2005-06 to study the effect of various herbicides and their mixtures on weeds and yield of wheat in Jammu region. Application of fenoxaprop +metribuzin (120+100 g/ha), sulfosulfuron+2,4-D (25+500 glha), clodinafop+metsulfuron methyl (60+2 g/ha), isoproturon+2,4-D (g/ha), metribuzin (175 or 200 g/ha) significantly reduced both grass and broad leaf weeds besides the N-uptake by weeds, whereas fenaxoprop (120 giha) and clodinafop (60 gka) proved effective against grass weeds only and metsulfuron methyl (4 g/ha) and 2,4-D (750 g/ha) controlled broad leaf weeds significantly than weedy check and other herbicide treatments in comparison thereby resulting in significant increase in the effective tillerslm and yield of wheat during both the years of experimentation. Application of metribuzin proved slightly phytotoxic to wheat crop, whereas isoproturon+2,4-D (750+500 g/ha) proved to be the best economical treatment. Maximum grain yield and effective tillerslm were recorded in weed free plots during both years.
Occurrence of shrimp species (Crustacea: Decapoda: Natantia: Penaeidea and Caridea) in Ubatuba Bay, Ubatuba, SP, Brazil

The species composition of Penaeidea and Caridea shrimp was studied in Ubatuba Bay, Sao Paulo, Brazil. Samples were taken monthly from September 1995 to August 1996, using two double-rig trawling nets. A total of 21 marine shrimps species were obtained, belonging to eight families. Ser- gestoids were represented by a single species of Sergestidae, while penaeoids comprised three families, Penaeidae, Sicyoniidae and Solenoceridae. Caridea shrimps belonged to two superfamilies, the Palaemonoidea, represented by Pa- laemonidae; and Alpheoidea by three families, Alpheidae, Ogyrididae and Hip- polytidae. Sicyonia laevigata Stimpson, 1871 and Nematopalaemon schmitti (Holthuis, 1950) represent first records in Sao Paulo State, Brazil.
Marcadores moleculares RAPD e descritores morfológicos na avaliação da diversidade genética de goiabeiras ( Psidium guajava L.) - doi: 10.4025/actasciagron.v32i4.4720

The knowledge of the genetic and phenotypic variability among different accessions of guava is important for supporting improvement programs of this specie in northern Rio de Janeiro state, which needs new cultivars able to generate income for local farmers. This work aimed to evaluate the genetic divergence among six cultivars and 19 accessions of guava via RAPD molecular markers and morphological characteristics. One hundred and seventeen polymorphic markers were obtained from 28 primers. The results showed a partial agreement between the methods of studied groupings, with the formation of 12 groups. The accessions ‘Vita 3’and ‘6’ were the most divergent, showing genetic distance of 0.663. The comparative analysis of groupings showed that RAPD markers and morphological descriptors were effective in discriminating the accessions and to show potential genetic variability useful in genetic improvement programs.

Production and detoxification of H2O2 in lettuce plants exposed to selenium.

Selenium is considered an essential element for animals. Despite that it has not been demonstrated to be essential for higher plants, it has been attributed with a protective role against reactive oxygen species in plants subjected to stress. In this study, lettuce plants (Lactuca sativa cv. Philipus) received different application rates (5, 10, 20, 40, 60, 80 and 120 μM) of selenite or selenate, with the aim of testing the effect of Se on the production and detoxification of H2O2 in non-stressed plants. The results indicate that the form selenate is less toxic than selenite; that is, the plants tolerated and responded positively to this element, and even increasing in growth up to a rate of 40 μM for the form selenate. On the contrary, the application of selenite triggered a higher foliar concentration of H2O2 and a higher induction of lipid peroxidation [malondialdehyde content and lipoxygenase activity] in comparison to that observed after the selenate application. Also, the plants treated with selenate induced higher increases in enzymes that detoxify H2O2, especially ascorbate peroxidase and glutathione (GSH) peroxidase, as well as an increase in the foliar concentration of antioxidant compounds such as ascorbate and GSH. These data indicate that an application of selenate at low rates can be used to prevent the induction in plants of the antioxidant system, thereby improving stress resistance.
Rôle d'histones methyltransférases spécifiques de H3K9 dans l'équilibre prolifération et différenciation cellulaire

Chez les eucaryotes, l’expression des genes depend en partie du degre de compaction de la chromatine. La structure chromatinienne est regulee par des marques dites epigenetiques,telles que les modifications post-traductionnelles des proteines structurelles de la chromatine, les histones. Ainsi, la methylation de la lysine 9 de l’histone H3 (H3K9) sur le promoteur des genes est essentiellement associee a la repression de la transcription. H3K9 est methylee par differentes enzymes appelees lysine methyltransferases (KMTs). L’objectif principal de mon projet de these a ete de mieux comprendre le role de principales KMTs de H3K9, que sontG9a, GLP, Suv39h1 et SETDB1, dans la regulation de l’equilibre entre proliferation et differenciation terminale. Pour cela, j’ai utilise le modele de differenciation terminale de cellules du muscle squelettique. En effet, durant la differenciation terminale, les myoblastes arretent de proliferer et fusionnent entre eux pour former de longues cellules multi nucleees que sont les myotubes. Ce processus implique, d’une part, l’expression des genes de differenciation musculaire et, d’autre part, la repression irreversible des genes associes a la proliferation cellulaire. L’introduction bibliographique de ce travail de these est separee en trois chapitres. Le premier chapitre porte sur la chromatine et ses modifications post-traductionnelles. Le second s’attache a decrire les roles de la methylation de H3K9 et, en particulier, des quatre KMTs sur lesquelles j’ai travaille durant ma these : G9a, GLP, SETDB1 et Suv39h1. Dans le troisieme chapitre, je presente le modele de la differenciation terminale du muscle squelettique. Dans la partie "Resultats", je decris deux des principales etudes que j’ai menees durant ma these. La premiere porte sur les roles antagonistes de G9a et GLP. La seconde porte sur le role de SETDB1 durant la differenciation musculaire. Les resultats que j’ai obtenus sont discutes dans cette partie. Je conclus ce manuscrit en discutant mes resultats de maniere plus generale et en proposant des perspectives a long terme. Enfin, une annexe presentera les autres articles de recherche auxquels j’ai participe pendant ma these.
Positional cloning of the Hybrid sterility 1 gene: fine genetic mapping and evaluation of two candidate genes

The Hybrid sterility 1 (Hstl ) gene affects fertility of male hybrids between certain laboratory strains (such as C57BL/ 10) and some Mus musculus musculus mice by causing a breakdown of spermatogenesis at the stage of primary spermatocytes. In the process of positional cloning of the Hstl gene, we generated a contig of bacterial artificial chromosomes and subsequently a low coverage sequence of the candidate region of the 129S1/SvImJ strain. Development of new genetic markers allowed us to narrow the Hst1 region from 580 to 360 kb. The products of two genes from this region, TATA-binding protein (Tbp) and proteasome subunit beta 1 (Psmb1), accumulate during spermatogenesis. These proteins have been described previously as having conserved C-terminal sequences and species-specific N-termini. We evaluated the candidacy of these genes for Hst1 by allelic sequencing and by real-time semiquantitative reverse-transcription PCR of testicular mRNAs.
Redescription of sperm structure and ultrastructure of Trichogramma dendrolimi (Hymenoptera: Chalcidoidea: Trichogrammatidae)

To verify the questionable description of sperm structure of Trichogramma dendrolimi, in relation to Chalcidoids, a reinvestigation was undertaken. The spermatozoa appear wavy along their entire length. A small acrosome, together with the anterior nuclear region, is surrounded by an extracellular sheath, from which filaments radiate. The nucleus is helicoidal and attached to the flagellum by a centriolar adjunct. The axoneme has the 9 + 9 + 2 microtubule arrangement pitched in a long helix, with the spiralling mitochondrial derivatives coiling around it. Therefore, the spermatozoa of T. dendrolimi are very similar to those of other chalcidoids and different from the first description. It is now possible to affirm that the helical sperm structures are an apomorphic homology for Trichogrammatidae as well as Eulophidae, Pteromalidae, Eurytomidae, Torymidae, Mymaridae and for some other chalcidoids, if not all.
Molecular and conventional identification and pathogenicity of Rhizoctonia solani isolates from tobacco (Nicotiana tabacum L.) in Samsun, Turkey.

A total of 101 fungal samples were isolated from tobacco (Nicotiana tabacum L.) plants in Samsun, Turkey and identified as Rhizoctonia solani. Of these samples, three were identified as belonging to Anastomosis Group (AG) -1-IB, 6 to AG-2-1, 25 to AG-4-HG-I and 67 to AG-4-HG-II, using ITS1-5.8S-ITS2 rDNA RFLP analysis, base sequence phylogenies and conventional characters, such as anastomosis reactions, morphology and thiamine requirement. For five isolates from both the AG-4-HG-I and AG-4-HG-II groups and for all isolates of the AG-1-IB and AG-2-1 groups, molecular analysis and pathogenicity tests were performed. All selected Rhizoctonia solani isolates were highly virulent to tobacco plants, causing symptoms resembling damping-off, except for isolate 55TkTB63, which was only moderately virulent.
