Ratings of L-DOPA-induced dyskinesia in the unilateral 6-OHDA lesion model of Parkinson's disease in rats and mice.

This unit provides detailed protocols for establishing rodent models of L-DOPA-induced dyskinesia. The 6-hydroxydopamine (6-OHDA) lesion procedure is described in more detail for mice than for rats since the lesioning procedure in rats has been described extensively in previous work and is less difficult to perform. Unlike primate models, rodent models of L-DOPA-induced dyskinesia are relatively s

Hybrid iterative reconstruction algorithm in brain CT: a radiation dose reduction and image quality assessment study.

Iterative reconstruction (IR) algorithms improve image quality and allow for radiation dose reduction in CT. Dose reduction is particularly challenging in brain CT where good low-contrast resolution is essential. Ideally, evaluation of image quality combines objective measurements and subjective assessment of clinically relevant quality criteria. Subjective assessment is associated with various pi

Molecular mechanisms of resistance to Rituximab and pharmacologic strategies for its circumvention.

The introduction of Rituximab has greatly improved therapeutic options for patients with B-cell non-Hodgkin lymphoma (B-NHL). However, a substantial fraction of patients with aggressive B-NHL fails first-line therapy, and most patients with relapsing indolent B-NHL eventually acquire Rituximab resistance. Molecular understanding of the underlying mechanisms facilitates the development of pharmacol

The metabolic syndrome and risk of myocardial infarction in familial hypertension (Hypertension Heredity in Malmö Evaluation study).

OBJECTIVES: The aim of this study was to examine whether three main definitions of the metabolic syndrome (MetS) - WHO, National Cholesterol Education Program-Adult Treatment Panel III and International Diabetes Federation - identify the same individuals and are able to predict incident myocardial infarction (MI) in families with essential hypertension. METHODS: The tested definitions were prospec

Prospects of stem cell therapy for replacing dopamine neurons in Parkinson's disease.

In Parkinson's disease (PD), the main pathology is a loss of nigrostriatal dopamine (DA) neurons. Clinical trials with intrastriatal transplantation of human embryonic mesencephalic tissue have shown that grafted DA neurons reinnervate the striatum, restore striatal DA release and, in some patients, induce major clinical benefit. Stem cells could provide an unlimited source of DA neurons for trans

CTH17-2: Energy-efficient cooperative relaying over fading channels with simple relay selection

We consider a cooperative wireless network where the source broadcasts data to relays, some or all of which cooperatively beamform to forward the data to the destination. The network is subject to an overall outage constraint. We generalize the standard approaches for cooperative communications in two respects: (i) we explicitly model and factor in the cost of acquiring channel state information (

Enhanced expressions of microvascular smooth muscle receptors after focal cerebral ischemia occur via the MAPK MEK/ERK pathway.

BACKGROUND: MEK1/2 is a serine/threonine protein that phosphorylates extracellular signal-regulated kinase (ERK1/2). Cerebral ischemia results in enhanced expression of cerebrovascular contractile receptors in the middle cerebral artery (MCA) leading to the ischemic region. Here we explored the role of the MEK/ERK pathway in receptor expression following ischemic brain injury using the specific ME

Implied Volatility and Risk Aversion in a Simple Model with Uncertain Growth

We show that a simple equilibrium model with uncertain growth is able to simultaneously generate patterns in implied volatility and risk aversion that are similar to the ones observed in the data. In addition, the model produces an implied pricing kernel that is increasing for particular levels of wealth.

Mouse development is not obviously affected by the absence of dermatan sulfate epimerase 2 in spite of a modified brain dermatan sulfate composition.

Dermatan sulfate epimerase 2 (DS-epi2), together with its homologue DS-epi1, transform glucuronic acid into iduronic acid in dermatan sulfate polysaccharide chains. Iduronic acid gives dermatan sulfate increased chain flexibility and promotes protein binding. DS-epi2 is ubiquitously expressed and is the predominant epimerase in brain. Here we report the generation and initial characterization of D

A multilevel analysis of condom use among adolescents in the European Union.

OBJECTIVES: This study examined which individual and national factors affect condom use among adolescents. STUDY DESIGN: Multilevel analysis. METHODS: This study reviewed the data on bullying, alcohol use and condom use provided by 18 European countries and subnational entities in the Health Behaviour in School-Aged Children survey. Another eight contextual variables were also analysed. Three mult

Rätten och den sociosymboliska sömnen - reflektioner om det industriella folkmordets eftereffekter

Combining cultural theory with the philosophy of law, this essay argues that the advent of state-managed, industrial genocide has brought about a crisis of confidence in the institutions of modern society. A wave of incrimination emanates from the holocaust, which primarily strikes against the institutions of law, but also affects the credibility of sociosymbolic mandate as such. Drawing on the wr
