Sustained, targeted, high-level transgene expression in primary B lymphocytes may be useful for gene therapy in B cell disorders. We developed several candidate B-lineage predominant self-inactivating lentiviral vectors (LC) containing alternative enhancer/promoter elements including : the immunoglobulin β (Igβ) promoter combined with the immunoglobulin µ enhancer (EµB29); and the endogenous BTK promoter with or without Eµ (EµBtkp or Btkp). LV-driven enhanced green fluorescent protein (eGFP) reporter expression was evaluated in cell lines and primary cells derived from human or murine hematopoietic stem cells (HSC). In murine primary cells, eµB29 and EµBtkp LV-mediated high-level expression in immature and mature B cells compared with all other lineages. Expression increased with B cell maturation and was maintained in peripheral subsets. Expression in T and myeloid cells was much lower in percentage and intensity. Similarly, both EµB29 and EµBtkp LV exhibited high-level activity in human primary B cells. In contrast to EµB29, Btkp and EµBtkp LV also exhibited modest actiity in myeloid cells, consistent with the expression profile of endogenous Bruton's tyrosine kinase (Btk). Notably, EµB29 end EµBtkp activity was superior in all expression models to an alternative, B-lineage targeted vector containing the EµS.CD19 enhancer/promoter. In summary, EµB29 and EµBtkp LV comprise efficient delivery platforms for gene expression in B-lineage cells. [less ▲]

The aim of this study is to develop representative simulation building energy data sets and benchmark models for the Egyptian residential sector. This study reports the results of a recent field survey for residential apartment buildings in Egypt. Two building performance simulation models are created reflecting the average energy consumption characteristics of air-conditioned residential apartments in Alexandria, Cairo and Asyut. Aiming for future evaluation of the cost and energy affects of the new Egyptian energy standard this study established two detailed models describing the energy use profiles for air-conditioners, lighting, domestic hot water and appliances in respect to buildings layout and construction. Using EnergyPlus simulation tool the collected surveyed data was used as input for two building simulation models. The simulation models were verified against the apartment characteristic found in the survey. This paper presents details of the building models including the energy use patterns and profiles created for this study. [less ▲]

This paper represents the very basic work of bio-climatic classification of north-east India into warm and humid, cool and humid and cold and cloudy zones. This classification is extremely useful to the building design for wide range of objectives such as climate responsive building design, building energy conservation, thermal comfort, out door design conditions, etc. This classification is based on the meteorological data collected over a period of more than 30 years, from Regional Meteorological Centre, Guwahati, India from 30 stations spread all over the region. Psychometric charts are prepared for each bio-climatic zone to assess the potential of solar passive design strategies for residential buildings. [less ▲]

Semiochemicals – informative molecules used in insect-insect or plant-insect interactions – have been considered within various integrated pest management IPM strategies. Herein, two sesquiterpenoids: E-β-farnesene and E-β-caryophyllene have been formulated for their potential properties as aphid enemies attractants. Indeed, E-β-farnesene, the alarm pheromone of many aphid species [1], has also been identified as a kairomone by attracting and inducing oviposition of aphid predators (Episyrphus balteatus De Geer (Diptera: Syrphidae)) [2-5] and by attracting aphid parasitoids (Aphidius ervi Haliday (Hymenoptera: Braconidae)) [6, 7]. E-β-caryophyllene was identified as a potential component of the aggregation pheromone of the Asian ladybird, Harmonia axyridis Pallas [8, 9]. The two products have been purified from essential oils of Matricaria chamomilla L. (Asteraceae) and Nepeta cataria L. (Lamiaceae) [10, 11]. Natural and biodegradable slow-release devices have been investigated in order to deliver these molecules. Moreover, due to their sensitivity to oxidation, the sesquiterpenes needed to be protected. For this purpose, alginate (hydrophilic matrix with low oxygen permeability) was used as polymer for the formulations: the main objective was to hold and deliver semiochemical substances in a controlled way. Consequently, a careful selection of alginates was realised for encapsulation. Formulated beads showed different structural and encapsulation properties depending on factors such as polymer concentration, ionic strength, type and concentration of cross-linker ion,... The gel structure influenced diffusion properties. Alginate formulations were characterized by texturometry and by confocal microscopy in order to observe the distribution of semiochemicals in alginate network. The last step consisted in studying release rate of semiochemicals in laboratory-controlled conditions by adapted trapping and Fast-GC procedures [10,11]. [less ▲]

Several features make bovine herpesvirus 4 (BoHV-4) attractive as a backbone for use as a viral expression vector and/or as a model to study gammaherpesvirus biology. However, these developments have been impeded by the difficulty in manipulating its large genome using classical homologous recombination in eukaryotic cells. In the present study, the feasibility of exploiting bacterial artificial chromosome (BAC) cloning and prokaryotic recombination technology for production of BoHV-4 recombinants was explored. Firstly, the BoHV-4 genome was BAC cloned using two potential insertion sites. Both sites of insertion gave rise to BoHV-4 BAC clones stably maintained in bacteria and able to regenerate virions when transfected into permissive cells. Reconstituted virus replicated comparably to wild-type parental virus and the loxP-flanked BAC cassette was excised by growing them on permissive cells stably expressing Cre recombinase. Secondly, BoHV-4 recombinants expressing Ixodes ricinus anti-complement protein I or II (IRAC I/II) were produced using a two-step mutagenesis procedure in Escherichia coli. Both recombinants induced expression of high levels of functional IRAC molecules in the supernatant of infected cells. This study demonstrates that BAC cloning and prokaryotic recombination technology are powerful tools for the development of BoHV-4 as an expression vector and for further fundamental studies of this gammaherpesvirus.

The aim of this study is to explore the development of children’s narratives in three different contexts that are favorable to the production of (self-)narratives: (i) at home with parent(s), (ii) at school with peers and (iii) with a researcher in psychology. 136 children aged from 3 to 13 have been recorded 50 minutes in each situation. Once transcribed, the data were morphosyntactically annotated and processed using multivariate exploratory techniques, including Correspondence Analysis, Principal Component and Classification Analysis. The results we obtained first demonstrated that contextual indicators were more significant than age in narrative production: conversations with parents were significantly more interactive whereas interactions between children turned out to be more regressive (i.e. simplified vocabulary, demonstrative pronouns). The situation with the psychologist was the one leading to the more elaborate narratives, as children seem to show greater language control with unfamiliar adults. However, age naturally impacts the linguistic complexity of narratives, both on the lexical and morphosyntactic levels. The results we obtained enabled us to observe a gradation in the complexity of textual productions, setting the roots of the future self-narratives the subjects will be able to develop later, during adolescence. Thus, the findings show different and significant aspects of the development of narratives and self-narratives in children’s speech, considering age and context. Last but not least, they also suggest the relevance of the application of text statistics methods to clinical psychology. [less ▲]

Whereas a large body of research has investigated the maturation of inhibition in relation to the prefrontal cortex, far less research has been devoted to environmental factors that could contribute to inhibition improvement. The aim of the current study was to test whether and to what extent parenting matters for inhibition development from 2 to 8 years of age. Data were collected from 421 families, with 348 mother–child dyads and 342 father–child dyads participating. Children’s inhibition capacities and parenting behaviors were assessed in a three-wave longitudinal data collection. The main analyses examined the impact of parenting on the development of children’s inhibition capacities. They were conducted using a multilevel modeling (MLM) framework. The results lead to the conclusion that both mothers and fathers contribute through their child-rearing behavior to their children’s executive functioning, even when controlling for age-related improvement (maturation) and important covariates such as gender, verbal IQ, and place of enrollment. More significant relations between children’s inhibition development and parenting were displayed for mothers than for fathers. More precisely, parenting behaviors that involve higher monitoring, lower discipline, inconsistency and negative controlling, and a positive parenting style are associated. [less ▲]
