Abnormal brainstem auditory response in young females with ADHD

Studies have shown that the auditory brain stem response (ABR) is often affected in neurodevelopmental disorders. The aim of this study is to investigate possible differences in ABR between young females with ADHD compared to control subjects. This study focuses on young females, age7–17 with ADHD, comparing the ABR of 43 young females with ADHD to 21 age- and gender-matched control subjects. Youn

Increased Levels of Hyaluronic Acid in Cerebrospinal Fluid in Patients with Vascular Dementia.

Hyaluronic acid (HA) has been shown to affect angiogenesis and the function of the blood-brain barrier, and a crucial role for HA in atherosclerosis has been described. We have recently demonstrated changes in the levels of HA in cerebrospinal fluid (CSF) in patients with Alzheimer's disease (AD) with documented vascular alterations. To further investigate if the level of HA in CSF can be used as

Representation of selected-reaction monitoring data in the mzQuantML data standard

The mzQuantML data standard was designed to capture the output of quantitative software in proteomics, to support submissions to public repositories, development of visualization software and pipeline/modular approaches. The standard is designed around a common core that can be extended to support particular types of technique through the release of semantic rules that are checked by validation so

Synthesis and biological activity of cymantrene and cyrhetrene 4-aminoquinoline conjugates against malaria, leishmaniasis, and trypanosomiasis.

Organometallic analogues of chloroquine show promise as new antimalarial agents capable of overcoming resistance to the parent drug chloroquine. Here, the synthesis and characterization of three new cymantrene (CpMn(CO)(3)) and cyrhetrene (CpRe(CO)(3)) 4-aminoquinoline conjugates with either an amine or amide linker are reported. The antimalarial activity of the new organometallic conjugates N-(2-

Human induced pluripotent stem cells in Parkinson's disease: A novel cell source of cell therapy and disease modeling.

Human induced pluripotent stem cells (hiPSCs) and human embryonic stem cells (hESCs) are two novel cell sources for studying neurodegenerative diseases. Dopaminergic neurons derived from hiPSCs/hESCs have been implicated to be very useful in Parkinson's disease (PD) research, including cell replacement therapy, disease modeling and drug screening. Recently, great efforts have been made to improve

Elastic and Piezoelectric Properties of Zincblende and Wurtzite Crystalline Nanowire Heterostructures.

The elastic and piezoelectric properties of zincblende and wurtzite crystalline InAs/InP nanowire heterostructures have been studied using electro-elastically coupled continuum elasticity theory. A comprehensive comparison of strains, piezoelectric potentials and piezoelectric fields in the two crystal types of nanowire heterostructures is presented. For each crystal type, three different forms of

Struggling with internal crisis communication: A balancing act between paradoxical tensions

The aim of this article is to elucidate the complexity of internal crisis communication by identifying and discussing different paradoxical tensions embedded within a large, complex, multi-professional organization. This article is based on a qualitative case study of a university hospital. Internal dimensions of crisis management have long been neglected within the field of crisis communication r

SEM study of overload effects during fatigue crack growth using an image analyzing technique and potential drop measures

To study the mechanisms affecting the crack propagation rate for fatigue cracks exposed to an overload, an in situ scanning electron microscope technique was used, together with potential drop measurements. High-resolution images were analysed with an image analysis program to measure the displacements along the crack, and the potential drop technique was employed to measure the electrical contact

Characterization of the chromosomal translocation t(10;17)(q22;p13) in clear cell sarcoma of kidney

Clear cell sarcoma of kidney (CCSK) is classified as a tumour of unfavourable histology by the National Wilms' Tumor Study Group. It has worse clinical outcomes than Wilms' tumour. Virtually nothing is known about CCSK biology, as there have been very few genetic aberrations identified to act as pointers in this cancer. Three cases of CCSK bearing a chromosomal translocation, t(10;17)(q22;p13), ha

Deubiquitinating activity of CYLD is impaired by SUMOylation in neuroblastoma cells.

CYLD is a deubiquitinating (DUB) enzyme that has a pivotal role in modulating nuclear factor kappa B (NF-κB) signaling pathways by removing the lysine 63- and linear-linked ubiquitin chain from substrates such as tumor necrosis factor receptor-associated factor 2 (TRAF2) and TRAF6. Loss of CYLD activity is associated with tumorigenicity, and levels of CYLD are lost or downregulated in different ty

Fibrinogen function is impaired in whole blood from patients with cyanotic congenital heart disease

Background: Patients with cyanotic congenital heart disease (CCHD) have haemostatic abnormities associated with bleeding and thrombo-embolic events. The haemostatic abnormalities are not fully understood, but recent studies indicate that elevated haematocrit and fibrinogen function may be of importance. The aim of this study was to characterise the haemostatic profile and examine the potential rol

A blessing in disguise? Banking crises and institutional change.

Weak economic growth is a contributing factor behind many banking crises. In this paper, we test whether banking crises cause long-term institutional change aimed at improving macroeconomic performance and thus indirectly reduce the risk of future crises. Our dataset consists of 22 developed and 34 developing countries covering the period from 1985 to 2009. The results show that banking crises cau

Loss-of-function mutations in SLC30A8 protect against type 2 diabetes.

Loss-of-function mutations protective against human disease provide in vivo validation of therapeutic targets, but none have yet been described for type 2 diabetes (T2D). Through sequencing or genotyping of ∼150,000 individuals across 5 ancestry groups, we identified 12 rare protein-truncating variants in SLC30A8, which encodes an islet zinc transporter (ZnT8) and harbors a common variant (p.Trp32

Family members' strategies when their elderly relatives consider relocation to a residential home : Adapting, representing and avoiding

The aim of this article is to reveal how family members act, react and reason when their elderly relative considers relocation to a residential home. Since family members are usually involved in the logistics of their elderly relative's relocation, yet simultaneously expected not to influence the decision, the focus is on how family members experience participation in the relocation process in a S

Intervention with feedback using Outcome Questionnaire 45 (OQ-45) in a Swedish psychiatric outpatient population. A randomized controlled trial.

Aim: The objective of the study was to evaluate the efficacy of the Outcome Questionnaire 45 (OQ-45) with feedback in a Swedish psychiatric outpatient population using a randomized controlled design. Method: In all 1720 patients made at least one regular visit to the clinics in the period 12 February 2007 to 10 February 2008 and received information about the study. Of these, 374 patients (22%) ag

The ecological impact of oceanic island colonization - a palaeoecological perspective from the Azores

Aim In many cases, human colonization drastically modified the ecosystems of remote oceanic islands before scientists arrived to document the changes. Palaeoecological records before and after human colonization provide insights into the original ecosystems and an assessment of subsequent human impact. We used pollen analysis to compare the impact of 15th century colonization of the Azores with th

Targeting Intermediates of [FeFe]-Hydrogenase by CO and CN Vibrational Signatures

In this work, we employ density functional theory to assign vibrational signatures of [FeFe]-hydrogenase intermediates to molecular structures. For this purpose, we perform an exhaustive analysis of structures and harmonic vibrations of a series of CN and CO containing model clusters of the [FeFe]-hydrogenase enzyme active site considering also different charges, counterions, and solvents. The pur
