The preference and costs of sleeping under light at night in forest and urban great tits

2019

Artificial light at night (ALAN) is an increasing phenomenon associated with worldwide urbanization. In birds, broad-spectrum white ALAN can have disruptive effects on activity patterns, metabolism, stress response and immune function. There has been growing research on whether the use of alternative light spectra can reduce these negative effects, but surprisingly, there has been no study to determine which light spectrum birds prefer. To test such a preference, we gave urban and forest great tits (Parus major) the choice where to roost using pairwise combinations of darkness, white light or green dim light at night (1.5 lux). Birds preferred to sleep under artificial light instead of dar…

The influence of serotonin- and other genes on impulsive behavioral aggression and cognitive impulsivity in children with attention-deficit/hyperacti…

2008

Contains fulltext : 70708.pdf (Publisher’s version ) (Open Access) ABSTRACT: BACKGROUND: Low serotonergic (5-HT) activity correlates with increased impulsive-aggressive behavior, while the opposite association may apply to cognitive impulsiveness. Both types of impulsivity are associated with attention-deficit/hyperactivity disorder (ADHD), and genes of functional significance for the 5-HT system are implicated in this disorder. Here we demonstrate the separation of aggressive and cognitive components of impulsivity from symptom ratings and test their association with 5-HT and functionally related genes using a family-based association test (FBAT-PC). METHODS: Our sample consisted of 1180 o…

German validation of the conners adult ADHD rating scale-self-report: confirmation of factor structure in a large sample of participants with ADHD.

2013

Objective: The Conners Adult ADHD Rating Scales (CAARS) assess symptoms specific to adults that are frequently used and have been translated into German. The current study tests the factor structure of the CAARS in a large sample of German adults with ADHD and compares the means of the CAARS subscales with those of healthy German participants. Method: CAARS were completed by 466 participants with ADHD and 851 healthy control participants. Confirmatory factor analysis was used to establish model fit with the American original. Comparisons between participants with ADHD and healthy controls and influences of gender, age, and degree of education were analyzed. Results: Confirmatory factor anal…

Analysis of thiamine transporter genes in sporadic beriberi

2014

Abstract Objective Thiamine or vitamin B 1 deficiency diminishes thiamine-dependent enzymatic activity, alters mitochondrial function, impairs oxidative metabolism, and causes selective neuronal death. We analyzed for the first time, the role of all known mutations within three specific thiamine carrier genes, SLC19 A2, SLC19 A3 , and SLC25 A19 , in a patient with atrophic beriberi, a multiorgan nutritional disease caused by thiamine deficiency. Methods A 44-year-old male alcoholic patient from Morocco developed massive bilateral leg edema, a subacute sensorimotor neuropathy, and incontinence. Despite normal vitamin B 1 serum levels, his clinical picture was rapidly reverted by high-dose in…

We analyzed for the first time the role of all known mutations within three specific thiamine carrier genes SLC19 A2 SLC19 A3 and SLC25 A19 in a patient with atrophic beriberi a multiorgan nutritional disease caused by thiamine deficiency. Methods: A 44-year-old male alcoholic patient from Morocco developed massive bilateral leg edema a subacute sensorimotor neuropathy and incontinence. Despite normal vitamin B1 serum levels his clinical picture was rapidly reverted by high-dose intramuscular thiamine treatment suggesting a possible genetic resistance. We used polymerase chain reaction followed by amplicon sequencing to study all the known thiamine-related gene mutations identified within the Human Gene Mutation Database. Results: Thirty-seven mutations were tested: 29 in SLC19 A2 6 in SLC19 A3 and 2 in SLC25 A19. Mutational analyses showed a wild-type genotype for all sequences investigated. Conclusion: This is the first genetic study in beriberi disease. We did not detect any known mutation in any of the three genes in a sporadic dry beriberi patient. We cannot exclude a role for other known or unknown mutations in the same genes or in other thiamine-associated genes in the occurrence of this nutritional neuropathy.HumansThiamineGenePolymerase chain reactionGeneticsMutationNutrition and DieteticsbiologyMembrane Transport ProteinsThiamine Deficiencymedicine.diseaseAlcoholismEndocrinologyMutationbiology.proteinThiamineMutations

The analysis of 51 genes in DSM-IV combined type attention deficit hyperactivity disorder: association signals in DRD4, DAT1 and 16 other genes.

2006

Contains fulltext : 35205.pdf (Publisher’s version ) (Closed access) Attention deficit hyperactivity disorder (ADHD) is a common neurodevelopmental disorder, starting in early childhood and persisting into adulthood in the majority of cases. Family and twin studies have demonstrated the importance of genetic factors and candidate gene association studies have identified several loci that exert small but significant effects on ADHD. To provide further clarification of reported associations and identify novel associated genes, we examined 1,038 single-nucleotide polymorphisms (SNPs) spanning 51 candidate genes involved in the regulation of neurotransmitter pathways, particularly dopamine, nor…

Genome-wide association scan of attention deficit hyperactivity disorder

2008

Contains fulltext : 70191.pdf (Publisher’s version ) (Closed access) Results of behavioral genetic and molecular genetic studies have converged to suggest that genes substantially contribute to the development of attention deficit/hyperactivity disorder (ADHD), a common disorder with an onset in childhood. Yet, despite numerous linkage and candidate gene studies, strongly consistent and replicable association has eluded detection. To search for ADHD susceptibility genes, we genotyped approximately 600,000 SNPs in 958 ADHD affected family trios. After cleaning the data, we analyzed 438,784 SNPs in 2,803 individuals comprising 909 complete trios using ADHD diagnosis as phenotype. We present t…

A functional variant of the serotonin transporter gene (SLC6A4) moderates impulsive choice in attention-deficit/hyperactivity disorder boys and sibli…

2011

Item does not contain fulltext BACKGROUND: Impulsive drive for immediate reward (IDIR) and delay aversion are dissociable elements of the preference for immediate over delayed rewards seen in attention-deficit/hyperactivity disorder (ADHD). We hypothesized that IDIR would be associated with dopamine regulating genes and delay aversion would be associated with serotonin-regulating genes. METHODS: Impulsive drive for immediate reward and delay aversion were measured in 459 male children and adolescents (328 ADHD and 131 unaffected siblings) with a laboratory choice task. The sample was genotyped for the 5HTT (SLC6A4) promoter serotonin-transporter-linked polymorphic region polymorphism and a …

The overstated generational gap in online news use? A consolidated infrastructural perspective

2021

Recent research by Taneja et al. suggested that digital infrastructures diminish the generational gap in news use by counteracting preference structures. We expand on this seminal work by arguing that an infrastructural perspective requires overcoming limitations of highly aggregated web tracking data used in prior research. We analyze the individual browsing histories of two representative samples of German Internet users collected in 2012 ( N = 2970) and 2018 ( N = 2045) and find robust evidence for a smaller generational gap in online news use than commonly assumed. While short news website visits mostly demonstrated infrastructural factors, longer news use episodes were shaped more by …
