Genetic variability in three species of Gymnotus Linnaeus, 1758 (Gymnotiformes: Gymnotidae) from Caracu stream of the upper Paraná River basin, Brazil
Rezende, Judy Ruiz;Renesto, Erasmo;Zawadzki, Cláudio Henrique;
Neotropical Ichthyology , 2009, DOI: 10.1590/S1679-62252009000400010
Abstract: the genetic variability of three gymnotus species from the caracu stream, a small tributary of the left margin of paraná river (brazilian upper paraná river floodplain), was estimated with data of 17 putative allozyme loci, which were obtained by using corn starch gel electrophoresis of 10 enzymatic systems: aspartate aminotransferase (e. c. 2.6.1.1), alcohol dehydrogenase (e. c. 1.1.1.1), esterase (e. c. 3.1.1.1), glucose dehydrogenase (e. c. 1.1.1.118), glycerol-3-phosphate dehydrogenase (e. c. 1.1.1.8), isocitrate dehydrogenase (e. c. 1.1.1.42), l-lactate dehydrogenase (e. c. 1.1.1.27), malate dehydrogenase (e. c. 1.1.1.37), superoxide dismutase (e. c. 1.15.1.1) and sorbitol dehydrogenase (e. c. 1.1.1.14). the genetic diversity was estimated as he = 0.3458 for g. pantanal, he = 0.2481 for g. inaequilabiatus, and he = 0.3152 for g. sylvius. the most divergent species were g. sylvius and g. pantanal (d = 0.117), and the most similar were g. inaequilabiatus and g. pantanal (d = 0.051). the data indicates that the observed genetic variability was very low and the expected variability estimated for these three species is very high, and the genetic differences among them are small. the data suggest that the process of speciation which produced these three species is recent.
The plastid-localized pfkB-type carbohydrate kinases FRUCTOKINASE-LIKE 1 and 2 are essential for growth and development of Arabidopsis thaliana

Abstract: Here, we report the characterization of Arabidopsis FLN knockout alleles to examine the contribution of each gene in plant growth, chloroplast development, and in mediating PEP-dependent transcription. We show that fln plants have severe phenotypes with fln1 resulting in an albino phenotype that is seedling lethal without a source of exogenous carbon. In contrast, fln2 plants display chlorosis prior to leaf expansion, but exhibit slow greening, remain autotrophic, can grow to maturity, and set viable seed. fln1 fln2 double mutant analysis reveals haplo-insufficiency, and fln1 fln2 plants have a similar, but more severe phenotype than either single mutant. Normal plastid development in both light and dark requires the FLNs, but surprisingly skotomorphogenesis is unaffected in fln seedlings. Seedlings genetically fln1-1 with dexamethasone-inducible FLN1-HA expression at germination are phenotypically indistinguishable from wild-type. Induction of FLN-HA after 24 hours of germination cannot rescue the mutant phenotype, indicating that the effects of loss of FLN are not always reversible. Examination of chloroplast gene expression in fln1-1 and fln2-1 by qRT-PCR reveals that transcripts of PEP-dependent genes were specifically reduced compared to NEP-dependent genes in both single mutants.Our results demonstrate that each FLN protein contributes to wild type growth, and acting additively are absolutely essential for plant growth and development.The plastid, an essential plant organelle, is the sole site of multiple biosynthetic pathways, such as de novo fatty acid and amino acid synthesis. After differentiation into the photosynthetically competent chloroplast, membrane-localized light harvesting complexes convert light energy into chemical energy and soluble enzymes reduce CO2 into various carbohydrates. Plastid genomes do not encode the complete repertoire of proteins required for these reactions; therefore, nuclear-encoded proteins are present in almost all plastid-l
Building on the evidence: Interventions promoting NCLEX success  [PDF]
Judy R. Hyland
Open Journal of Nursing (OJN) , 2012, DOI: 10.4236/ojn.2012.23036
Abstract: Nurse educators have implemented a variety of teaching/learning interventions in an effort to maintain or improve student success and NCLEX pass rates. An integrative review of literature from 2004 through 2010 was conducted to investigate the specific strategies used and their outcome effectiveness. Five major databases were queried using the search terms of test taking, preparation, remediation, success, review course, HESI, Pearson, Kaplan, ATI, Hurst and NCLEX. Of the resultant 40 articles, 14 met the inclusion criteria and provided measurable outcomes. All studies implemented multiple strategies at a single institution; 7 included standardized testing and 7 used review courses as one of the multiple intervenetions. When standardized testing was a strategy included with individual and curricular changes, NCLEX passage improvement was found for 6 schools. Review courses coupled with individual and cohort interventions improved success in 5 of 7 schools. This review discusses commonalities and differences of a combination of teaching/learning interventions that improved NCLEX success.
Reproductive strategies and genetic variability in tropical freshwater fish
Lassala, Maria Dolores Peres;Renesto, Erasmo;
Genetics and Molecular Biology , 2007, DOI: 10.1590/S1415-47572007000400030
Abstract: we estimated the genetic variability of nine fish species from the brazilian upper paraná river floodplain (astyanax altiparanae, hoplias malabaricus, leporinus lacustris, loricariichthys platymetopon, parauchenipterus galeatus, pimelodus maculatus, rhaphiodon vulpinus, roeboides paranensis and serrasalmus marginatus) based on data for 36 putative allozyme loci obtained using corn starch gel electrophoresis of 13 enzymatic systems: aspartate aminotransferase (ec 2.6.1.1), acid phosphatase (ec 3.1.3.2), esterase (ec 3.1.1.1), glycerol-3-phosphate dehydrogenase (ec 1.1.1.8), glucose-6-phosphate dehydrogenase (ec 1.1.1.49), glucose-6-phosphate isomerase (ec 5.3.1.9), iditol dehydrogenase (ec 1.1.1.14), isocitrate dehydrogenase - nadp+ (ec 1.1.1.42), l-lactate dehydrogenase (ec 1.1.1.27), malate dehydrogenase (ec 1.1.1.37), malate dehydrogenase-nadp+ (ec 1.1.1.40), phosphoglucomutase (ec 5.4.2.2) and superoxide dismutase, (ec 1.15.1.1). the mean expected heterozygosity varied from zero to 0.147. when data from the literature for 75 species of tropical fish were added to the nine species of this study, the heterozygosity values differed significantly among the groups of different reproductive strategies. the highest mean heterozygosity was for the non-migratory without parental care, followed by the long-distance migratory, and the lowest mean was for the non-migratory with parental care or internal fecundation.

Abstract: Introduction: The main component of the endocardial acceleration signal (SonR) is today used for cardiac resynchronization therapy (CRT) optimization. This prospective, single center pilot study focuses on another signal component, SonR4 that may provide further information on the atrial activity. Methods and Results: SonR signal and ECG tracings were recorded simultaneously during a CRT-D optimization procedure in 15 patients (12 men, 68 ± 9.5 years, ischemic heart disease 53%) indicated for CRT. Correlation between SonR4 signal, recorded using SonR and atrial contraction, identified by Echo Doppler was evaluated by Pearson and Student’s t tests under different Atrio-Ventricular (AV) delay programming. From 15 consecutive screened patients, 9 had concomitant analyzable SonR4 and ECG recordings and were included in the study population. The presence of the SonR4 component was systematically correlated to the presence of the A wave. A significant correlation was observed between SonR4 and A wave timings (r = 0.75, p = 0.02) according to different AV delays, with a high reproducibility in SonR4 assessment. Conclusion: A strong correlation between SonR4 and atrial contraction timings was observed, further suggesting that SonR4 is a marker of the atrial contraction. Additional assessments in larger populations are required to confirm these results and build further applications.
Transpersonal Psychology: Mapping Spiritual Experience
Dwight Judy
Religions , 2011, DOI: 10.3390/rel2040649
Abstract: The first Journal of Transpersonal Psychology was published in 1969. Since this signal event, transpersonal psychology has emerged as a field of theory and application. A way has been made in Western psychology for the appreciation and study of interior subjective awareness, the domain of spiritual experience. One of the most recent contributions, the Wilber-Combs Lattice, offers a typology to account for both developmental processes throughout the human life span, as well as different qualities of spiritual experience.
Can We Praxize Second Language Teacher Education? An Invitation to Join a Collective, Collaborative Challenge*
Sharkey,Judy;
íkala, Revista de Lenguaje y Cultura , 2009,
Abstract: the purpose of this essay is to begin a conversation on how we might make praxis, or ''praxizing,'' i.e., fostering and sustaining an ongoing dialogical relationship between theory and practice, an integral part of second language teacher education. this project is firmly located in critical sociocultural theories of, and approaches to, language learning and teaching, and requires active, participatory and collaborative inquiries by teacher educators and teacher learners across the multiple levels and stages of teacher learning from entry level courses to teaching practica and beyond. examples of praxis/praxizing are included as well as some of the challenges to doing this work.
Imbalanced literacy? How a US national educational policy has affected English learners and their teachers
Sharkey,Judy;
Colombian Applied Linguistics Journal , 2009,
Abstract: learning and teaching are always affected by institutional contexts and their policies, ranging from the classroom policies that teachers establish or enact-tacitly or explicitly, to the larger rings of policy set by schools, organizations, districts, states, and/or country. how is policy enacted on a local level? how does such policy affect the needs and realities of students and teachers? how does listening to teacher concerns contribute to valid critiques of policy? this article addresses those questions as they pertain to the us education policy known as no child left behind (nclb). it is told through the perspectives and experiences of six english language teachers in three public schools in one urban school district in the northeastern united states. although teachers' concerns are often dismissed as anecdotal, they can offer valuable insights into the weaknesses of policies and/or programs. in the often, dichotomous worlds of policy and practice, this story highlights the critical need to attend to both.
Community Participation in Ethnic Minority Cultural Heritage Management in China: A Case Study of Xianrendong Ethnic Cultural and Ecological Village
Judy Xu
Papers from the Institute of Archaeology , 2007, DOI: 10.5334/pia.307
Abstract: Heritage protection in China has long been considered as the responsibility of the government. However, over the last 20 years, a number of heritage projects, mainly in ethnic minority regions, have attempted to engage with local communities. These seem to be an attractive alternative to top-down approaches. This paper explores the implications of a bottom-up approach for Chinese ethnic minority heritage management through an examination of the Ethnic Cultural and Ecological Village project in Xianrendong in Yunnan province. It is a result of my fascination with the project’s concept and my desire to understand its key characteristics, application and potential for future development in China. After a discussion of cultural performance, modernisation and inside/outside encounters, I conclude by suggesting that well-planned and well-informed community participation, with realistic control, contributes to reconciling tourism and cultural heritage conservation.
A Comparison of Clothing Styles and Values of Korean and Japanese Youth Subcultures
Judy Park
Cross-Cultural Communication , 2011, DOI: 10.3968/975
Abstract: Korea and Japan are two countries in Asia with a long shared history and what seem from afar to be similar values, such as modesty, filial piety and diligence. However, a more in-depth look into the two countries shows that Korean and Japanese people in fact have different minds and values. Both countries have five to six established youth subcultures in the 2000s that reflect Korean and Japanese society, and the pressures, values and lifestyles of youths. The aim of this study was to compare the youth subcultures of Korea and Japan, focusing on their clothing styles, and interpret why the differences in styles exist, using aspects of their respective social circumstances, status of youths, and traditional values as indexes, and to ultimately help deepen understanding of the relationship between clothes and culture, youths today, and the issues and trends that most affect youths in Korea and Japan. Key words: Korea; Japan; Youth; Subculture; Style; 2000s Resumé: La Corée et le Japon sont deux pays en Asie, avec une longue histoire commune et qui semblent avoir des valeurs similaires, telles que la modestie, la piété filiale et la diligence. Cependant, un regard plus en profondeur sur les deux pays montre que les Coréens et les Japonais ont en fait des esprits et des valeurs différents. Les deux pays ont de cinq à six sous-cultures établies des jeunes dans les années 2000 qui reflètent la société, les pressions, les valeurs et les modes de vie des jeunes coréens et japonais. Le but de cette étude était de comparer les sous-cultures des jeunes en Corée et au Japon, en se concentrant sur leurs styles vestimentaires, et interpréter pourquoi il existe des différences dans les style, du point de vue de leurs conditions sociales respectives, du statut des jeunes, et des valeurs traditionnelles, afin d'approfondir la compréhension de la relation entre les vêtements et la culture, les jeunes d'aujourd'hui, les enjeux et les tendances qui affectent le plus les jeunes en Corée et au Japon. Mots-clés: Corée; Japon; Jeunes; Sous-Culture; Style; 2000s
