Twenty-eight children with attention-deficit hyperactivity disorder (ADHD) were examined with SPECT (single photon emission computed tomography). Seven of the children had abnormal distribution of the regional cerebral blood-flow (rCBF) on visual evaluation and 10 had abnormal EEG findings. The only clinical finding that differentiated the group with normal from abnormal rCBF was behaviour symptom

Functional genomics methods are used to investigate the huge amount of information contained in genomes. Numerous experimental methods rely on the use of oligo- or polynucleotides. Nucleotide strand hybridization forms the underlying principle for these methods. For all these techniques, the probes should be unique for analyzed genes. In addition to being unique for the studied genes, the probes s

The fossiliferous Eocene carbonate reservoir interval of the offshore Hasdrubal Field has a diagenetic history in which dolomitisation of micrite-rich facies has significantly enhanced reservoir quality. Using published information on the diagenetic evolution, digital textural representations of the limestones and dolostones are created using the Multi-Component Architecture Method (MCAM). This te

Monitoring of individual biomarkers has the potential of explaining the hazard of survival outcomes. In practice, these measurements are intermittently observed and are known to be subject to substantial measurement error. Joint modelling of longitudinal and survival data enables us to associate intermittently measured error-prone biomarkers with risks of survival outcomes and thus plays an import

Are daughters of older mothers less fertile? The human mutation rate is high and increases with chronological age. As female oocytes age, they become less functional, reducing female chances at successful reproduction. Increased oocyte mutation loads at advanced age may be passed on to offspring, decreasing fertility among daughters born to older mothers. In this paper we study the effects of mate

ObjectiveTo explore critical care nurses’ lived experiences of transferring intensive care patients between hospitals.MethodsA phenomenological hermeneutic approach using data generated through individual interviews with 11 critical care registered nurses.SettingTwo general intensive care units in Sweden.FindingsFive themes were identified: it depends on me; your care makes a difference; being exp

Museum collections around the world contain billions of specimens, including rare and extinct species. If their genetic information could be retrieved at a large scale, this would dramatically increase our knowledge of genetic and taxonomic diversity information, and support evolutionary, ecological and systematic studies. We here present a target enrichment kit for 2953 loci in 1753 orthologous n

The transmission of vibrations, and its reduction, in the far-field of the surface of the ground due to a harmonic load acting over a strip, is investigated theoretically. A possible vibration attenuation device that has shown some promise is the "wave impedance block" (WIB). The principle of this is to modify the modal wave propagation regime of the ground by introducing an artificial stiffened l

The composition of enclosure materials used in many TV sets sold on the European market has changed significantly since the early 1990s. To determine the potential impact of this change on TV fire safety, a review of European and US TV set fire statistics has been carried out. TV set fires can have internal electrical causes due to faults not apparent at the time of manufacture, simple wear and te

Rural households in Asian developing countries such as Vietnam have been participating in non-farm activities for decades, yet impacts beyond the economy of these households are little understood. Using evidence from available literature and two case studies from rural Vietnam, this paper exposes a range of socio-cultural impacts of non-farm activities. An increased social tension driven by a wide

Solar ultraviolet radiation (UVR) is an important environmental threat for organisms in aquatic systems, but its temporally variable nature makes the understanding of its effects ambiguous. The aim of our study was to assess potential fitness costs associated with fluctuating UVR in the aquatic zooplankter Daphnia magna. We investigated individual survival, reproduction and behaviour when exposed

While social movement scholars have long recognized the importance of collective memory and shared pasts in the construction of collective identities, less attention has focused on the role of imagined futures. Based on a long-term ethnographic study of radical left-libertarian groups in Sweden, this paper explores the role of utopia in structuring, influencing, and evaluating actions and practice

BACKGROUND: Contact allergen prevalences often change. Continual surveillance is necessary to detect trends in sensitization rates and emerging allergens.OBJECTIVE: To identify the prevalence of, and trends in, the positive reactions to each allergen in the baseline series during a 12-year period in Thailand.METHODS: The medical records of 2803 patients who underwent patch testing at the Contact D

The emergent patterns of collective motion are thought to arise from application of individual-level rules that govern how individuals adjust their velocity as a function of the relative position and behaviours of their neighbours. Empirical studies have sought to determine such rules of interaction applied by 'average' individuals by aggregating data from multiple individuals across multiple traj

Base-catalyzed depolymerization of black liquor retentate (BLR) from the kraft pulping process, followed by ultrafiltration, has been suggested as a means of obtaining low-molecular-weight (LMW) compounds. The chemical complexity of BLR, which consists of a mixture of softwood and hardwood lignin that has undergone several kinds of treatment, leads to a complex mixture of LMW compounds, making the

This article discusses a key methodological difficulty in conducting qualitative research close to home: the issue of overthinking. Whereas MALINOWSKI's concern regarding imponderabilia, i.e., the risk of not thinking about the subtle phenomena of everyday life, has long haunted ethnographers and qualitative researchers, not least those working "at home," we highlight an issue of overponderabilia,

Basis pursuit (BP), basis pursuit deNoising (BPDN), and least absolute shrinkage and selection operator (LASSO) are popular methods for identifying important predictors in the high-dimensional linear regression model (Formula presented.). By definition, when (Formula presented.), BP uniquely recovers (Formula presented.) when (Formula presented.) and (Formula presented.) implies (Formula presented

Coronavirus disease 2019 (COVID-19) has caused global disruption and a significant loss of life. Existing treatments that can be repurposed as prophylactic and therapeutic agents may reduce the pandemic’s devastation. Emerging evidence of potential applications in other therapeutic contexts has led to the investigation of dietary supplements and nutraceuticals for COVID-19. Such products include v
