Strategies for structuring interdisciplinary education in Systems Biology: an European perspective

2016

Systems Biology is an approach to biology and medicine that has the potential to lead to a better understanding of how biological properties emerge from the interaction of genes, proteins, molecules, cells and organisms. The approach aims at elucidating how these interactions govern biological function by employing experimental data, mathematical models and computational simulations. As Systems Biology is inherently multidisciplinary, education within this field meets numerous hurdles including departmental barriers, availability of all required expertise locally, appropriate teaching material and example curricula. As university education at the Bachelor’s level is traditionally built upon…

Common Hits Approach: Combining Pharmacophore Modeling and Molecular Dynamics Simulations.

2017

We present a new approach that incorporates flexibility based on extensive MD simulations of protein-ligand complexes into structure-based pharmacophore modeling and virtual screening. The approach uses the multiple coordinate sets saved during the MD simulations and generates for each frame a pharmacophore model. Pharmacophore models with the same pharmacophore features are pooled. In this way the high number of pharmacophore models that results from the MD simulation is reduced to only a few hundred representative pharmacophore models. Virtual screening runs are performed with every representative pharmacophore model; the screening results are combined and rescored to generate a single hi…

Early Cognitive Training Rescues Remote Spatial Memory but Reduces Cognitive Flexibility in Alzheimer’s Disease Mice

2020

Background: Spatial memory dysfunction has been demonstrated in mouse models of Alzheimer’s disease (AD) which is consistent with the clinical finding that the early signature of AD includes difficulties in the formation and/or storage of a memory. A stored memory—a long term memory—can be modulated via process called as memory retrieval that can either lead toward memory reconsolidation or even memory extinction. Objective: We aim to shed light on the fate of the spatial memory during memory reactivation and memory extinction using a water maze task. Methods: In Set-up I, we trained 3-month-old mice (wild-type mice and mice with cerebral β-amyloidosis) and assessed the fate of remote memor…

Evaluating the stability of pharmacophore features using molecular dynamics simulations.

2016

Abstract Molecular dynamics simulations of twelve protein—ligand systems were used to derive a single, structure based pharmacophore model for each system. These merged models combine the information from the initial experimental structure and from all snapshots saved during the simulation. We compared the merged pharmacophore models with the corresponding PDB pharmacophore models, i.e., the static models generated from an experimental structure in the usual manner. The frequency of individual features, of feature types and the occurrence of features not present in the static model derived from the experimental structure were analyzed. We observed both pharmacophore features not visible in …

Contrasting coping styles meet the wall: A dopamine driven dichotomy in behavior and cognition

2017

Individual variation in the ability to modify previously learned behaviour is an important dimension of trait correlations referred to as coping styles, behavioral syndromes or personality. These trait clusters have been shaped by natural selection, and underlying control mechanisms are often conserved throughout vertebrate evolution. In teleost fishes, behavioral flexibility and coping style have been studied in the high (HR) and low-responsive (LR) rainbow trout lines. Generally, proactive LR trout show a behaviour guided by previously learned routines, while HR trout show a more flexible behaviour relying on environmental cues. In mammals, routine dependent vs flexible behavior has been …

Determinants for Tight and Selective Binding of a Medicinal Dicarbene Gold(I) Complex to a Telomeric DNA G-Quadruplex: a Joint ESI MS and XRD Investi…

2016

International audience; The dicarbene gold(I) complex [Au(9-methylcaffein-8-ylidene)(2)]BF4 is an exceptional organometallic compound of profound interest as a prospective anticancer agent. This gold(I) complex was previously reported to be highly cytotoxic toward various cancer cell lines invitro and behaves as a selective G-quadruplex stabilizer. Interactions of the gold complex with various telomeric DNA models have been analyzed by a combined ESI MS and X-ray diffraction (XRD) approach. ESI MS measurements confirmed formation of stable adducts between the intact gold(I) complex and Tel 23 DNA sequence. The crystal structure of the adduct formed between [Au(9-methylcaffein-8-ylidene)(2)]…

Foam rolling is thought to improve muscular performance and flexibility as well as to alleviate muscle fatigue and soreness. For this reason, foam rolling has become a popular intervention in all kinds of sport settings used to increase the efficiency of training or competition preparation as well as to speed post-exercise recovery. The objective of this meta-analysis was to compare the effects of foam rolling applied before (pre-rolling as a warm-up activity) and after (post-rolling as a recovery strategy) exercise on sprint, jump, and strength performance as well as on flexibility and muscle pain outcomes and to identify whether self-massage with a foam roller or a roller massager is more…

Conductas de aprendizaje en niños con trastorno del espectro autista con y sin comorbilidad con déficit de atención e hiperactividad

2018

La literatura ha explorado los problemas en el aprendizaje que presentan los niños con trastorno del espectro autista (TEA), pero apenas se ha analizado el impacto de la comorbilidad con déficit de atención e hiperactividad (TDAH) sobre el aprendizaje en niños con TEA. Objetivos. 1) Analizar las diferencias en la conducta de aprendizaje de niños con TEA con y sin comorbilidad con TDAH y niños con desarrollo típico (TD); 2) Investigar la asociación entre diferentes dominios de conductas de aprendizaje y problemas conductuales y emocionales, en niños con TEA y niños con TEA+TDAH. Método. Participaron 87 niños (30 con diagnóstico de TEA de alto funcionamiento, 22 con TEA+TDAH y 36 con TD entre…

Remittance behaviours of foreigners in Italy

2015

This article investigates the determinants of remittance behaviours among foreigners in Italy and intends to gain a better understanding of the temporal pattern of remittances. The analysis is based on data from the 2009 “Italian Statistics on Income and Living Conditions of Households with Foreigners”. The decisions on whether to remit and how much to remit are separately yet simultaneously estimated using a zero-inflated beta regression model. The findings reveal that remittances are driven by a mix of altruistic and self-interest motives that may persist for many years. Many covariates included in the model have a different effect on the propensity to remit and on the relative amount of …

Meditation practice is associated with a values-oriented life: the mediating role of decentering and mindfulness

2017

Clarification of personal values and meditation practice has been associated in most meditation traditions and in academic texts. Both values-related behavior and meditation practice increases well-being, but their relationship has not been well studied. It has been suggested that values, together with self-regulation, psychological flexibility, and exposure, are key mechanisms of action in mindfulness. The aims of this study were to explore the association between meditation and values and to examine the processes involved in this relation. A sample of 235 meditation-na < ve participants and 274 subjects with varying levels of experience in meditation practice completed an online assessmen…
