This study investigates astrocytic glutamate uptake in the iron-induced animal model of posttraumatic epilepsy. Since formation of free radicals may be involved in epileptogenesis after brain trauma and hemorrhage the effects of the nitrone radical scavenger alpha-phenyl-tert-N-butyl nitrone (PBN) were also studied. Animals received an intracortical iron injection, or were sham-operated. They were

The extracellular homeostasis of glutamate in the brain is maintained by the efficient uptake into astroglial cells. The high extracellular glutamate levels seen during seizures are therefore probably a result of both an increased synaptic release and a deranged glutamate uptake. In this study we used immuno-blotting technique to measure the cortical levels of the astrocytic glutamate transport pr

BACKGROUND: This observational microdialysis (MD) study of 33 subarachnoid hemorrhage patients explores brain interstitial levels of glutamine, glutamate, lactate and pyruvate, and their relationship to clinical status and clinical course at the neurointensive care unit.METHODS: The focus was on ischemic events, defined by clinical criteria or by radiology, and the significance of brain interstiti

Binding studies with 125I-Tyr labelled hyaluronan (HA) on a cultured rat colon cancer cell line were performed to characterize the association of HA to tumour cells in vitro. Results show a specific and saturable binding (Kd=1.36 nM) which indicates the presence of an HA binding receptor on the tumour cells. There is a specific constant increase of cell-associated HA over time, which indicates tha

Solid single-Li+-ion conducting polymer electrolytes are currently explored for safe high-temperature lithium batteries. In the present work we have prepared and studied materials based on alternating mesogen-like naphthalene sulfonate units interconnected by flexible poly(ethylene oxide) (PEO) segments in order to induce microphase separation and physical crosslinking. These segmented polymers we

We make a number of comments on Chebyshev polynomials for general compact subsets of the complex plane. We focus on two aspects: asymptotics of the zeros and explicit Totik–Widom upper bounds on their norms.

Background and objectives:Health anxiety is a common problem and is associated with frequent primary carevisits, increased health care costs, and poor prognosis and low recovery rates. Previous research shows thatimagery rescripting (IR) is a promising treatment technique for various disorders. To date, IR has not beenexamined as a viable treatment for health anxiety. The purpose of the present fe

The field of psychotherapy suffers from the lack of an integrative meta-perspective on the large variety of existing psychotherapies and on the therapeutic skills involved. In the present paper, it is suggested that the development of a more comprehensive view of this field may be facilitated if we differentiate between three modes of psychotherapy, which require different therapeutic core skills:

This paper examines whether social spending cushions the effect of globalization on within‐country inequality. Using information on disposable and market income inequality and data on overall social spending, and health and education spending from the ILO and the World Bank/WHO, we analyze whether social spending moderates the association between economic globalization and inequality. The results
