Expression and characterization of the recombinant juvenile hormone epoxide hydrolase (JHEH) from Manduca sexta.

1998

The cDNA of the microsomal Juvenile Hormone Epoxide Hydrolase (JHEH) from Manduca sexta was expressed in vitro in the baculovirus system. In insect cell culture, the recombinant enzyme (Ms-JHEH) was produced at a high level (100 fold over background EH catalytic activity). As expected, Ms-JHEH was localized in the microsomal fraction with a molecular mass of approximately 50 kDa. Ms-JHEH showed a substrate and inhibitor spectrum similar to the wild type JHEH isolated from eggs of M. sexta. Its enzymatic activity was the highest for Juvenile Hormone III. Ms-JHEH hydrolyzed several trans-epoxides faster than cis-epoxides. A putative hydroxyl-acyl enzyme intermediate was isolated suggesting a …

Decision-making Styles in Adolescent Offenders and Non-offenders: Effects of Emotional Intelligence and Empathy

2021

The literature indicates that adolescents with delinquent behavior have greater difficulty making rational decisions and show lower emotional intelligence and empathy. Decision-making is a set of complex processes associated with neurobiological, cognitive, emotional, and social factors which help regulate and guide behavior, which could be influenced by emotional intelligence and empathy. A comparative, correlational, and predictive study was conducted to analyze relationships and influence of emotional intelligence and empathy in decision-making styles in adolescent offenders and non-offenders. 808 Colombian adolescents between 14 and 18 years of age participated (50p offenders). The resu…

Satisfacción con la Vida y Factores Asociados en una Muestra de Menores Infractores

2018

El objetivo de esta investigación es, por un lado, conocer la relación existente entre el apoyo social percibido, la empatía emocional y cognitiva, la satisfacción con la vida, la expresión de ira como rasgo y cinco dimensiones del autoconcepto −académico, social, emocional, familiar y físico− en una muestra de residentes en un centro de reeducación de menores infractores en cumplimiento de medidas judiciales. Por otro lado, el trabajo pretende conocer cuáles son las variables que mejor predicen la satisfacción con la vida en la misma muestra. Los principales resultados son la existencia de correlaciones positivas de satisfacción con la vida con apoyo social y autoconcepto, así como que el …

I minori sono Cosa Nostra? Criminalità organizzata, devianza minorile e sistema giudiziario a Palermo e Catania

2009

Do All Juveniles Belong to Cosa Nostra? Palermo and Catania are the two main cities of Sicily - Despite the fact that they share similar problems, such as underdevelopment, unemployment and social deprivation, the Juvenile Courts of the two cities apply different policies when dealing with juvenile deviants. When the same kind of crimes committed by juvenile defendants are considered, the Palermo court is found to be more lenient than its counterpart in Cata235 nia. Seeking an explanation for this discrepancy, the two authors discuss figures and use qualitative material to argue that it must be connected to the different relationship between organised crime and juvenile deviance in the two …

Data from: Localization of QTL for diapause and other photoperiodically regulated life-history traits important in adaptation to seasonally varying e…

2015

Seasonally changing environments at high latitudes present great challenges for the reproduction and survival of insects, and photoperiodic cues play an important role in helping them to synchronize their life cycle with prevalent and forthcoming conditions. We have mapped quantitative trait loci (QTL) responsible for the photoperiodic regulation of four life history traits, female reproductive diapause, cold tolerance, egg-to-eclosion development time and juvenile body weight in Drosophila montana strains from different latitudes in Canada and Finland. The F2 progeny of the cross was reared under a single photoperiod (LD cycle 16:8), which the flies from the Canadian population interpret a…

Protracted juvenile neuronal ceroid-lipofuscinosis.

Dementia in the Neuronal Ceroidlipofuscinoses

2001

Dementia is defined as a decline in cognitive abilities such as impairment of memory, reasoning, behaviour, attention, motivation and effectiveness. The term usually implies that normal mature mental capability was achieved before, and it is therefore mostly ascribed to adult patients.

HLA antigens and immunoresponsiveness to insulin in insulin-dependent diabetes mellitus.

2008

HLA-A and B antigens were determined in 112 patient with insulin-dependent juvenile onset diabetes mellitus, who could be subdivided into “non” and “high responders” to insulin. The data revealed a trend of an association of these diabetes subgroups with only one of the diabetes-associated antigens HLA-B8 and HLA-BW15 and indicated the existence of at least two different genetic constellations for susceptibility to juvenile diabetes mellitus. One form with a strong immune-response to insulin seemed to be associated with HLA-BW 15 and the other form without humoral immunoreactivity to insulin seemed to be associated with the presence of HLA-B8 and the absence of HLA-B7.

Postembryonic development of Zophobas atratus Fab. (Coleoptera: Tenebrionidae) under crowded or isolated conditions and effects of juvenile hormone a…

1995

Abstract Pupation in Zophobas atratus is dependent on isolation and this provides a model for study of the onset of metamorphosis in beetles. We have analyzed the effects of isolation vs grouping on certain developmental parameters; the number of larval instars; their duration and weight. Sex differences were detected, such as the occurrence of regressive moults in females. Moreover, the development of Z. atratus is discussed in relation to Tenebrio molitor , the physiological timing of which appeared in part extendable to Z. atratus . Experiments show that 4–6 days of isolation are required for commencement of metamorphosis, as indicated by an immobile crooked posture observed at the end o…

Field application of the juvenile hormone analogue fenoxycarb against hopper bands of Locusta migratoria capito in Madagascar

1997

Summary Field trials have been carried out to examine the suitability of the JHA fenoxycarb in locust control. Laboratory tests have shown that a variety of JHAs, including fenoxycarb, applied to last instar larvae increased mortality, induced morphogenetic defects during metamorphosis, reduced fertility and provoked solitarisation of gregarious hoppers. The phase shift was indicated by green coloration and the acquisition of morphological and behavioural characteristics typical for solitary locusts. The present field experiments should clarify whether or not the effects observed in the laboratory are also observed with hopper bands in their natural habitat and if swarm formation and emigra…
