Anthropometric measurements and nutritional assessment in autism spectrum disorders: A systematic review

2015

Abstract Adequate nutrient intake is essential for health. Due to food selectivity and restrictive diets, people with autism spectrum disorder (ASD) may have impaired nutritional status, which could affect their growth. We present a systematic review of publications (1970–2013) on anthropometric measurements and nutritional assessment in this population. The limited research published on growth and nutritional status has found contradictory results. Nutritional assessment has indicated limited food variety in the ASD population but has not confirmed significant differences with respect to recommended intakes or controls. In addition to the lack of control groups, studies in this area have s…

Phase-selective low molecular weight organogelators derived from allylated D-mannose

2022

In the last decades, synthesis and design of low molecular weight organogelators has gained increasing attention due to their versatile use in, for example, cosmetics, biomedicine and oil spill remediation. In this work, three potential gelators have been prepared from allylated d-mannose. Both the gelators and the corresponding gels formed were thoroughly characterized by crystallography, FTIR spectroscopy, SEM, rheometry and NMR spectroscopy, in solution and in solid state. The results showed that two of the compounds phase-selectively form gels with hydrocarbon solvents. The most promising gelator compound is alkene terminated, with the unsaturated end functionality not critical for gel …

Long-Term Educational Sustainability: Educational Innovation in Social Vulnerability Contexts

2017

This paper investigates the behavior of children from low socioeconomic status families and examines the effects of a socioemotional education program on aggression in children. The results of the program are compared according to the children’s gender and age, the family structure, the parents’ educational attainment, and social status. The results show that applying socioemotional education programs reduces children’s aggression and encourages positive development during adolescence. This positive development fosters open, expressive behavior.

Synthesis and Structure-Affinity Relationships of Spirocyclic Benzopyrans with Exocyclic Amino Moiety

2019

σ1 and/or σ2 receptors play a crucial role in pathological conditions such as pain, neurodegenerative disorders, and cancer. A set of spirocyclic cyclohexanes with diverse O-heterocycles and amino moieties (general structure III) was prepared and pharmacologically evaluated. In structure-activity relationships studies, the σ1 receptor affinity and σ1:σ2 selectivity were correlated with the stereochemistry, the kind and substitution pattern of the O-heterocycle, and the substituents at the exocyclic amino moiety. cis-configured 2-benzopyran cis-11b bearing a methoxy group and a tertiary cyclohexylmethylamino moiety showed the highest σ1 affinity ( Ki = 1.9 nM) of this series of compounds. In…

Acid–base properties of functionalised tripodal polyamines and their interaction with nucleotides and nucleic acids

2010

Novel, highly positively charged tripodal polyamines with appended heterocyclic moieties revealed an intriguing panel of protonation species within the biologically relevant range. Studied compounds bind nucleotide monophosphates by mostly electrostatic interactions but only the imidazole analogue showed selectivity toward UMP in respect to other nucleotides. Strong binding of all the studied compounds to both ds-DNA and ds-RNA is to some extent selective toward the latter, showing rather rare RNA over DNA preference.

Sensory systems sequentially extract increasingly complex features. ON and OFF pathways, for example, encode increases or decreases of a stimulus from a common input. This ON/OFF pathway split is thought to occur at individual synaptic connections through a sign-inverting synapse in one of the pathways. Here, we show that ON selectivity is a multisynaptic process in the Drosophila visual system. A pharmacogenetics approach demonstrates that both glutamatergic inhibition through GluClα and GABAergic inhibition through Rdl mediate ON responses. Although neurons postsynaptic to the glutamatergic ON pathway input L1 lose all responses in GluClα mutants, they are resistant to a cell-type-specifi…

The impact of children’s socioemotional development on parenting styles: the moderating effect of social withdrawal

2020

This study focused on associations between children’s socioemotional development (prosocial behaviour, internalizing and externalizing problems) and parenting styles (affection, behavioural control, and psychological control), and the moderating role of children’s social withdrawal (as a temperamental characteristic) in these associations. Children’s socioemotional development (n = 314) were rated by teachers at three-time points (grades 1–3). Parents completed questionnaires measuring their parenting styles at the same three-time points. The level of social withdrawal was obtained at the end of kindergarten from teachers’ reports. Panel analysis showed that prosocial behaviour was associat…
