This study investigated electroencephalographic (EEG) activity and its developmental course in attention deficit hyperactivity disorder (ADHD) throughout the lifespan, as well as the accuracy of EEG parameters in distinguishing ADHD patients from typically developing individuals. Three minutes eyes closed resting EEG was compared between 62 individuals with ADHD (36 children, 26 adults) and 55 typically developing individuals (30 children, 25 adults). EEG activity and maturation did not differ between individuals with ADHD and typically developing individuals. However, despite comparable developmental course between clinical groups, persistent elevated theta/beta ratio and reduced relative beta power were observed in the ADHD inattentive subtype compared to the ADHD combined subtype and controls across the lifespan. Therefore, a maturational deviation rather than a maturational delay may underlie a subgroup of ADHD. EEG based classification failed for ADHD but proved successful for age. These findings emphasize heterogeneity in ADHD throughout the lifespan and question clinical utility of conventional EEG approaches for diagnostic purposes in ADHD.

The global increase of overweight and obesity in children and adults is one of the most prominent public health threats, often accompanied by insulin resistance, hypertension, and dyslipidemia. The simultaneous occurrence of these health problems is referred to as metabolic syndrome. Various criteria have been proposed to define this syndrome, but no general consensus on the specific markers and the respective cut-offs has been achieved yet.

The developmental theory of ageing proposes that age-specific decline in the force of natural selection results in suboptimal levels of gene expression in adulthood, leading to functional senescence. This theory explicitly predicts that optimising gene expression in adulthood can ameliorate functional senescence and improve fitness. Reduced insulin/IGF-1 signalling (rIIS) extends the reproductive lifespan of Caenorhabditis elegans at the cost of reduced reproduction.

This article aims to illustrate the pivotal role that the environment plays in early child development (ECD), drawing upon data derived from the ethnographic research on children's daily routines. Participant observation and in-depth interviews were conducted over the course of several fieldwork periods (2013-2018). The concept of "mutual raising" is employed to examine the daily interactions between middle-aged children and their domestic animals.

Background: Ramadan during pregnancy is associated with adverse offspring health outcomes. Recent evidence from Europe indicates that maternal diet during non-fasting hours might alleviate these effects. This study describes fasting, diet, and sleep habits among pregnant Muslims in Kaduna, Nigeria, and assesses impacts on neonatal health in this setting.

One of the main endpoints for the evaluation of Developmental and Reproductive Toxicology (DART) studies is the determination of potential effects of a test substance on the skeleton during foetal development. In the course of a DART study according to the OECD 414 guideline, 400 to 500 gestational day 20-old (GD20), alizarin red and alcian blue-stained (ARAB) rat foetuses have to be assessed by a teratology expert, which is a time consuming and sub-optimally documented process. We have developed a method which allows for a standardised, comprehensive, quick and easy to perform, head-to-toe digital documentation of ARAB-stained GD20 rat foetuses.
