Applications of lentiviral vectors for biology and gene therapy of neurological disorders.

Recombinant lentiviral vectors (rLV) are powerful tools for gene transfer to the central nervous system (CNS) and hold great potential as a therapeutic gene therapy strategy for neurological disorders. Recent data indicate that rLVs are suitable for functional studies in the CNS by over expression or knock down of specific proteins. Based on a variety of lentiviruses species, different vector syst

Inhibition of Ras-guanine nucleotide-releasing factor 1 (Ras-GRF1) signaling in the striatum reverts motor symptoms associated with L-dopa-induced dyskinesia.

l-dopa-induced dyskinesia (LID) is a common debilitating complication of dopamine replacement therapy in Parkinson's disease. Recent evidence suggests that LID may be linked causally to a hyperactivation of the Ras-ERK signaling cascade in the basal ganglia. We set out to determine whether specific targeting of Ras-guanine nucleotide-releasing factor 1 (Ras-GRF1), a brain-specific activator of the

Cerebral palsy in children born after in vitro fertilization. Is the risk decreasing?

BACKGROUND: Infants born after in vitro fertilization (IVF) differ from spontaneously conceived infants in a number of aspects which could increase the risk for future cerebral palsy (CP), e.g., multiple births, preterm births, neonatal complications. AIMS: To follow up children conceived by IVF with respect to risk for CP. METHODS: Infants born after IVF were identified from all IVF clinics in Sw

Biochemical and functional correlates of an increased membrane density of caveolae in hypertrophic rat urinary bladder.

Organ hypertrophy is often found to be associated with changes in the expression of caveolins and altered density of caveolae in the membrane. A plethora of signalling intermediaries are associated with caveolae and loss of caveolae has profound effects on contractility of the urinary bladder. We hypothesized that smooth muscle hypertrophy caused by bladder outflow obstruction (BOO) might lead to

A bi-hyperbolic finite volume method on quadrilateral meshes

A non-oscillatory, high resolution reconstruction method on quadrilateral meshes in 2D is presented. It is a two-dimensional extension of Marquina's hyperbolic method. The generalization to quadrilateral meshes allows the method to simulate realistic flow problems in complex domains. An essential point in the construction of the method is a second order accurate approximation of gradients on an ir

Sustainability of transport biofuels from a legal perspective

The article investigates the notion of transport biofuels, their possible advantages and disadvantages in comparison to traditional fossil fuels, and sustainability requirements that need be stated to their quality and production methods from a legal perspective. The research results indicate that the understanding of what makes the quality and production of transport biofuels sustainable is still

High-resolution Vuv Spectroscopy Using Pulsed-laser Sources

The resonance spectroscopic techniques - level-crossing, optical double resonance and quantum-beat spectroscopy - have been employed following pulsed laser excitation. The use of pulsed lasers has enabled spectroscopic studies of atomic structures and radiative lifetimes in the UV/VUV spectral region.

Innovation in knowledge intensive industries: The nature and geography of knowledge links

Knowledge has become a key source of competitiveness for advanced regions and nations, indicating a transformation of capitalism towards a "knowledge economy". Knowledge intensive sectors in production and in services have a lead in this respect, they can be considered as role models for the future. The innovation process, the mechanisms of knowledge exchange and the respective linkages in those i

N1421K mutation in the glycoprotein Ib binding domain impairs ristocetin- and botrocetin-mediated binding of von Willebrand factor to platelets.

von Willebrand disease (VWD) is a common inheritable bleeding disorder caused by deficiency of von Willebrand Factor (VWF), which is involved in platelet adhesion and aggregation. We report a family consisting of three patients with VWD characterized by an apparently normal multimeric pattern, moderately decreased plasma factor VIII (FVIII) and VWF levels, and disproportionately low plasma VWF:RCo

Defective insulin secretion by chronic glucagon receptor activation in glucose intolerant mice.

Stimulation of insulin secretion by short-term glucagon receptor (GCGR) activation is well characterized, however, the effect of long-term GCGR activation on beta-cell function is not known, but of interest, since hyperglucagonemia occurs early during development of type 2 diabetes. Therefore, we examined whether chronic GCGR activation affects insulin secretion in glucose intolerant mice. To indu

Oncogenic signaling from the hematopoietic growth factor receptors c-Kit and Flt3.

Signal transduction in response to growth factors is a strictly controlled process with networks of feedback systems, highly selective interactions and finely tuned on-and-off switches. In the context of cancer, detailed signaling studies have resulted in the development of some of the most frequently used means of therapy, with several well established examples such as the small molecule inhibito
