ROP, the Drosophila Sec1 homolog, interacts with syntaxin and regulates neurotransmitter release in a dosage-dependent manner.
1998
The Sec1 family of proteins is thought to function in both non-neuronal and neuronal secretion, although the precise role of this protein family has not been defined. Here, we study the function of ROP, the Drosophila Sec1 homolog, in neurotransmitter release. Electrophysiological analyses of transgenic lines overexpressing ROP and syntaxin, a presynaptic membrane protein, indicate that ROP interacts with syntaxin in vivo. Characterization of four point mutations in ROP shows that they fall into two phenotypic classes. Two mutations cause a dramatic reduction in both evoked and spontaneous neurotransmitter release. In contrast, the other two mutations reveal an increase in evoked neurotrans…
What to Expect and What to Focus on in SQL Query Teaching
2019
In the process of learning a new computer language, writing erroneous statements is part of the learning experience. However, some errors persist throughout the query writing process and are never corrected. Structured Query Language (SQL) consists of a number of different concepts such as expressions, joins, grouping and ordering, all of which by nature invite different possible errors in the query writing process. Furthermore, some of these errors are relatively easy for a student to fix when compared to others. Using a data set from three student cohorts with the total of 744 students, we set out to explore which types of errors are persistent, i.e., more likely to be left uncorrected by…
Human R1441C LRRK2 regulates the synaptic vesicle proteome and phosphoproteome in a Drosophila model of Parkinson's disease
2016
International audience; Mutations in leucine-rich repeat kinase 2 (LRRK2) cause late-onset, autosomal dominant familial Parkinsons disease (PD) and variation at the LRRK2 locus contributes to the risk for idiopathic PD. LRRK2 can function as a protein kinase and mutations lead to increased kinase activity. To elucidate the pathophysiological mechanism of the R1441C mutation in the GTPase domain of LRRK2, we expressed human wild-type or R1441C LRRK2 in dopaminergic neurons of Drosophila and observe reduced locomotor activity, impaired survival and an age-dependent degeneration of dopaminergic neurons thereby creating a new PD-like model. To explore the function of LRRK2 variants in vivo, we …
Phytosociology and ecology of deciduous forests in Tajikistan (Middle Asia)
2017
Aims: To present the first syntaxonomical classification for the mesophilous deciduous forests of the PamirAlai Mountains in Tajikistan with some remarks on its environmental gradients. Location: Tajikistan. Methods: Altogether 201 relevés were sampled between 2008‒2013 using the seven-degree cover-abundance scale of Braun-Blanquet. They were classified by the modified TWINSPAN method using the four-step interval scale with cutoff levels of 0%, 2%, 5% and 10% and total inertia as a measure of cluster heterogeneity. Diagnostic species were identified using the phi coefficient as a fidelity measure. Detrendended Correspondence Analysis was used to determine the relation between samples, veget…
The Olea europaea L. var. sylvestris (Mill.) Lehr. forests in the Mediterranean area
2019
This paper examines the forest communities dominated by Olea europaea L. var. sylvestris (Mill.) Lehr. that have been described up until now in the Mediterranean Region (including other isolated extrazonal areas in the northwestern Iberian Peninsula and in Northern Turkey) as more or less evolved aspects of woods, microwoods and high maquis that principally tend to make up climacic and edapho-climacic “series heads”. These forma- tions maintain a significant large-scale distributive potential within the infra- and thermomediterranean bioclimate belts (with a few penetrations into the mesomediterranean) with a dry-subhumid (and sometimes humid) ombrotype; however, they are currently quite ra…
E. Rh. 686 ἀλλὰ: una cuestión sintáctica
2012
La adición de en E. Rh. 686, propuesta por Dindorf y adoptada por Diggle, ofrece una interpretación más coherente de este verso no solo en términos sintácticos sino también con respecto a la acción dramática y teatral. The addition of in E. Rh. 686 proposed by Dindorf and adopted by Diggle offers a more coherent interpretation of this line not only in syntactics terms but also in respect of the dramatic and theatrical action.
Children's exploration of the concepts of home and belonging: Capturing views from five European countries.
2021
Understanding one's sense of belonging is a central part of identity formation and self-awareness; feeling safe somewhere, with specific people is identified as a basic human need. This paper explores the ideas of children from three age groups in five different European as they discussed the concepts of ‘home’ and ‘belonging’. Findings showed that the children's ideas could be organised into six interrelated aspects: Spatiality, Materiality, Multiplicity, Social Relations, Affect, and Dislocation. Whilst there were differences in the ways that the children conceptualised home across the classes, even the youngest children were able to describe their ideas using metaphors and abstract conce…
Ortotipografía científica en publicaciones médico-quirúrgicas: la normativa académica relativa a la prefijación
2015
El objetivo del presente artículo es analizar el grado de cumplimiento de la normativa académica relativa a la correcta escritura de las palabras prefijadas (recogida en la nueva Ortografía de 2010) que realizan algunas publicaciones periódicas de carácter científico-técnico y, en concreto, del ámbito médico-quirúrgico. Se trata de una labor de profundización en un estudio anterior (Aguilar Ruiz 2012: 9-12). Para ello, comentamos los errores e incorrecciones más recurrentes de un corpus de publicaciones científicas argentinas de finales de 2012. The aim of this paper is to analyze the degree of compliance on the correct academic writing prefixed words (contained in the new spelling) that pe…
Expertise in folk music alters the brain processing of Western harmony
2012
In various paradigms of modern neurosciences of music, experts of Western classical music have displayed superior brain architecture when compared with individuals without explicit training in music. In this paper, we show that chord violations embedded in musical cadences were neurally processed in a facilitated manner also by musicians trained in Finnish folk music. This result, obtained by using early right anterior negativity (ERAN) as an index of harmony processing, suggests that tonal processing is advanced in folk musicians by their long-term exposure to both Western and non-Western music.
Time-Course of Grammatical Processing in Deaf Readers: An Eye-Movement Study.
2019
Abstract Twenty participants who were deaf and 20 chronological age-matched participants with typical hearing (TH) (mean age: 12 years) were asked to judge the correctness of written sentences with or without a grammatically incongruent word while their eye movements were registered. TH participants outperformed deaf participants in grammaticality judgment accuracy. For both groups, First Pass and Total Fixation Times of target words in correct trials were significantly longer in the incongruent condition than in the congruent one. However, whereas TH students showed longer First Pass in the target area than deaf students across congruity conditions, deaf students made more fixations than t…
