Previous studies have used recombinant adeno-associated viral (rAAV) vectors to deliver glial cell line-derived neurotrophic factor (GDNF) in the substantia nigra to protect the nigral dopamine (DA) neurons from 6-hydroxydopamine-induced damage. However, no regeneration or functional recovery was observed in these experiments. Here, we have used an rAAV-GDNF vector to express GDNF long-term (6 mon
Vitamin D receptor (VDR) gene polymorphisms have been implicated in susceptibility to tuberculosis (TB), but reports have been inconsistent. We genotyped the VDR single-nucleotide polymorphisms (SNPs) FokI, BsmI, ApaI, and TaqI in 1139 case patients and control subjects and 382 families from The Gambia, Guinea, and Guinea-Bissau. The transmission-disequilibrium test on family data showed a signifi
We prove the existence of the old and metal-rich moving group HR 1614. This is done using the new Hipparcos parallaxes in combination with metallicities derived from Strömgren photometry, supported by dynamical simulations of the evolution of old moving groups in the galactic potential. A new selection criterion for this moving group is presented as well as a new, extended sample of probable membe
This study is based on a total cohort (N = 192) of people born in 1902 and 1903 and living in southern Sweden. Subjects were assessed at baseline when 67 years of age and on eight further occasions over 34 years or until death. The participation rate in the nine examinations ranged from 78-100%. Interviews, psychological tests, and medical examinations were used as well as information on medical d
1. Studies of aquatic environments have shown that community organisation may strongly affect ecosystem functioning. One common phenomenon is a change in nutrient level following a shift in the fish community composition. Although several hypotheses have been suggested, there is no consensus on which mechanisms are involved. Our study evaluated indirect effects of benthivorous fish on the biogeoch
As reduction of sample complexity is a central issue in membrane proteomic research, the need for new pre-fractionation methods is significant. Here we present a method for fast and efficient enrichment of Escherichia coli inner membranes expressing a His-tagged integral membrane L-fucose-proton symporter (FucP). An enriched inner membrane fraction was obtained from a crude membrane mixture using
We present CHS, a computer program designed to calculate the condensation energy of the homogeneous superconducting electron gas. The correlation energy, which we treat at the level of the RPA, is an essential ingredient for the construction of a local density approximation in the framework of density functional theory for superconductors (SCDFT) [Kurth et al., Phys. Rev. Lett. 83 (1999) 2628].
Spectrographic graphite electrodes were modified through adsorption with laccase from Trametes versicolor. The laccase-modified graphite electrode was used as the working electrode in an amperometric flow-through cell for monitoring phenolic compounds in a single line flow injection system. The experimental conditions for bioelectrochemical determination of catechol were studied and optimized. The
The thalassaemia syndromes, endemic in the Mediterranean area, the Middle East, the Indian subcontinent, the Far East and in tropical Africa, are the most common hereditary disorders in humans, and millions of people are affected by diseases. Due to a widespread population flow between continents in recent past centuries, the thalassaemias are now occurring with relatively high frequency in many n
I focus on the distinction between sensation and perception. Perceptions contain additional information that is useful for interpreting sensations. Following Grush, I propose that emulators can be seen as containing (or creating) hidden variables that generate perceptions from sensations. Such hidden variables could be used to explain further cognitive phenomena, for example, causal reasoning.
Two approaches based on alkaline hydrolysis, in combination with either stir-bar sorptive extraction (SBSE) or sonication, were developed for the determination of banned azo dyes in bovine leather. All dyes were determined indirectly by measuring their corresponding harmful amines, formed after chemical reduction. Quantification was performed by employing standard addition methodology to compensat
BACKGROUND: Blockade of CD40 ligand (CD40L; CD154, gp39) is a potential treatment for autoimmune disease and allograft rejection. However, CD40L-/- mice are capable of mobilizing cellular immune responses to viral, parasitic, and intracellular bacterial infections as well as rejecting skin grafts with nearly the same efficiency as wild-type mice. CD40L-deficient mice (CD40L-/-) or wild-type mice t
Information on the first excited states in the N = Z = 41 nucleus Nb-82 sheds light on the competition of isospin T = 0 and T = 1 states in the A similar to 80 region. The measurement was performed at the GSI laboratory using fragmentation of a Ag-107 primary beam at 750 MeV/u on a 4 g/cm(2) Be-9 target. The fragments were separated and identified unambiguously in the FRagment Separator. Three exc
The field of plant cell wall biology is constantly growing and consequently so is the need for more sensitive and specific probes for individual wall components. Xyloglucan is a key polysaccharide widely distributed in the plant kingdom in both structural and storage tissues that exist in both fucosylated and non-fucosylated variants. Presently, the only xyloglucan marker available is the monoclon
The startup of a chemical plate reactor is investigated. A hybrid startup control scheme is presented and a discussion is made on how hybrid transition points could be chosen to allow safe startup despite actuator limitations, process nonlinearities and model uncertainties. The event-driven startup improves the robustness to uncertainties and disturbances, since each part of the startup is a
Pressurized liquid extractions were performed on eight sediments in order to investigate if a modified US EPA method (100 degrees C, 100 bar, n-heptane/acetone (1:1), 2 x 5 min) provided exhaustive extractions of polychlorinated biphenyls (PCBs) from sediment, and to study if the extractability of PCBs from the different sediments was affected by characteristics of the sediment. The recovery from
