Early changes in the hypothalamic region in prodromal Huntington disease revealed by MRI analysis.

Huntington disease (HD) is a fatal neurodegenerative disorder caused by an expanded CAG repeat. Its length can be used to estimate the time of clinical diagnosis, which is defined by overt motor symptoms. Non-motor symptoms begin before motor onset, and involve changes in hypothalamus-regulated functions such as sleep, emotion and metabolism. Therefore we hypothesized that hypothalamic changes occ

Depoliticising water conflict. The quest for functional peacebuilding in the Red Sea-Dead-Sea-Water-Conveyance project.

This article analyses the nexus of technocracy-peacebuilding and its implications on water conflicts and hydropolitics. It is a conceptual exploration, which advances an interdisciplinary approach by combining theories from two distinct research fields: peacebuilding and transboundary water management. It probes the argument that synergies between water management, development and peacebuilding fr

Inhibition of mitogen-activated protein kinase 1/2 in the acute phase of stroke improves long-term neurological outcome and promotes recovery processes in rats.

Extracellular signal-regulated kinase (ERK) 1/2 is activated during acute phase of stroke and contributes to stroke pathology. We have found that acute treatment with MEK1/2 inhibitors decrease infarct size and neurological deficits two days after experimental stroke. However it is not known whether benefits of this inhibition persist long-term. Therefore, the aim of this study was to assess neuro

Multiple Constraints Driven System-on-Chip Test Time Optimization

The cost oftesting SOCs (systems-on-chip) is highly related to the testapplication time. The problem is that the test application timeincreases as the technology makes it possible to design highlycomplex chips. These complex chips include a high number of faultsites, which need a high test data volume for testing, and the hightest data volume leads to long test application times. For modularcore-b

Ornithine decarboxylase and extracellular polyamines regulate microvascular sprouting and actin cytoskeleton dynamics in endothelial cells.

The polyamines are essential for cancer cell proliferation during tumorigenesis. Targeted inhibition of ornithine decarboxylase (ODC), i.e. a key enzyme of polyamine biosynthesis, by alpha-difluoromethylornithine (DFMO) has shown anti-neoplastic activity in various experimental models. This activity has mainly been attributed to the anti-proliferative effect of DFMO in cancer cells. Here, we provi

Prospectively isolated CD133/CD24-positive ependymal cells from the adult spinal cord and lateral ventricle wall differ in their long-term in vitro self-renewal and in vivo gene expression.

In contrast to ependymal cells located above the subventricular zone (SVZ) of the adult lateral ventricle wall (LVW), adult spinal cord (SC) ependymal cells possess certain neural stem cell characteristics. The molecular basis of this difference is unknown. In this study, antibodies against multiple cell surface markers were applied to isolate pure populations of SC and LVW ependymal cells, which

Polysaccharide-K (PSK) increases p21(WAF/Cip1) and promotes apoptosis in pancreatic cancer cells.

Polysaccharide-K (PSK, Krestin(®)) is a natural remedy and one of the most commonly used medicinal mushroom extracts. It has been used as oral adjuvant treatment in cancer therapy in Japan and other Asian countries for more than 40 years. PSK is thought to be an immune modulator, however, its antitumor actions remain undefined. The aim of the present study was to investigate underlying mechanisms

Histopathological examinations of rat brains after long-term exposure to GSM-900 mobile phone radiation.

In order to mimic the real life situation, with often life-long exposure to the electromagnetic fields emitted by mobile phones, we have investigated in a rat model the effects of repeated exposures under a long period to Global System for Mobile Communication-900MHz (GSM-900) radiation. Out of a total of 56 rats, 32 were exposed once weekly in a 2-h period, for totally 55 weeks, at different aver

Dynamic admission control and resource reservation for WCDMA

Current and next generation wireless networks including 3rd generation (3G) and beyond are expected to provide a wide range of multimedia services with different QoS constraints. Call admission control (CAC) and resource reservation (RR) for mobile communication are of the most important issues that guarantee system efficiency and QoS required for different services in a very scarce resource as th

Social influence and corporate behaviour - A case study of interdependent decision-making in Sweden's publicly traded firms

In the course of a few months in 1997, about 20 per cent of Stockholm Stock Exchange's primary-list firms transferred to the Exchange's secondary list due to a new tax policy. Drawing on a theory of social influence, we suggest that the transfer decisions depended both on the firms' social embeddedness with other firms in the population at risk and their economic predisposition to make such transf

An electrically small frequency reconfigurable antenna with a wide tuning range

An electrically small frequency-reconfigurable antenna with a very wide tuning band is proposed. Three varactor diodes are used to achieve the tunable capacitance. With a modifled feeding structure, the measured tuning range of the fabricated antenna reaches from 457.5 to 894.5 MHz, and the tuning band enhancement is also explained through an equivalent circuit analysis.

Upper extremity deep venous thrombosis in the population-based Malmö thrombophilia study (MATS). Epidemiology, risk factors, recurrence risk, and mortality.

BACKGROUND: Deep venous thrombosis (DVT) is much less common in the upper than in the lower extremity. Furthermore, there is limited information on risk factors for and the prognosis of upper extremity (UE)DVT in the general population. AIMS: To estimate incidence, risk factors, and prognosis in UEDVT. MATERIAL AND METHODS: Among a total of 1203 patients with venous thromboembolism (VTE) diagnosed

Primary Disseminated Multifocal Ewing Sarcoma: Results of the Euro-EWING 99 Trial.

PURPOSE To improve the poor prognosis of patients with primary disseminated multifocal Ewing sarcomas (PDMES) with a dose-intense treatment concept. PATIENTS AND METHODS From 1999 to 2005, 281 patients with PDMES were enrolled onto the Euro-EWING 99 R3 study. Median age was 16.2 years (range, 0.4 to 49 years). Recommended treatment consisted of six cycles of vincristine, ifosfamide, doxorubicin, a

Effects of a Standard Versus Comprehensive Oral Care Protocol Among Intubated Neuroscience ICU Patients: Results of a Randomized Controlled Trial.

The purpose of the study was to compare changes in oral health during intubation until 48 hours after extubation in neuroscience intensive care unit (ICU) patients enrolled in a standard or a comprehensive oral care protocol. The effects of manual toothbrushing (standard group, n = 31) were compared with those of tongue scraping, electric toothbrushing, and moisturizing (comprehensive group, n = 2
