Gating of cutaneous input to cerebellar climbing fibres during a reaching task in the cat

1. Task-dependent modulation of cutaneous input to climbing fibres projecting to the C1, C2 and C3 zones in the cerebellar paravermal lobule V was investigated in awake cats during performance of a reaching task. 2. Climbing fibre responses resulting from low intensity (non-noxious) electrical stimulation of the ipsilateral superficial radial nerve were recorded as extracellular field potentials i

Generation of clusters of free eosinophil granules (Cfegs) in seasonal allergic rhinitis

Generation of clusters of free eosinophil granules (Cfegs), through lysis of eosinophils, has recently been proposed as a major paradigm for ultimate activation of airway mucosal eosinophils. In the present study involving patients with seasonal allergic rhinitis, we have investigated whether generation of Cfegs in the nasal mucosa is a feature of allergic rhinitis. Nasal mucosal biopsies were obt

Structural study of adsorption of isonicotinic acid and related molecules on rutile TiO2(110) I: XAS and STM

X-ray absorption spectroscopy (XAS) and scanning tunneling microscopy (STM) have been used to study the absorption of monolayers of the pyridinecarboxylic acid monomers (isonicotinic acid, nicotinic acid, and picolinic acid) and benzoic acid on a rutile TiO2(1 1 0) surface. We find that the pyridine and phenyl rings are oriented with their planes largely perpendicular to the surface. The azimuthal

Salman Rushdie och liberalismens heliga ko

Ställd inför det religiöst motiverade dödsdomen mot en välkänd författare har opinionen i väst stirrat sig blind på en enda aspekt av "Rushdie-affären": den hotade tryckfriheten. Denna artikel analyserar andra sidor av konflikten och söker dess rötter i problem som uppkommer i ett multikulturellt samhälle – problem som även finns i Sverige.

Attenuation correction in SPECT based on transmission studies and Monte Carlo simulations of build-up functions

The quantitative information in SPECT images is distorted by photon attenuation and contribution of photons scattered in the object. It is, therefore, important to know the distribution of different attenuating tissues in order to be able to perform a proper attenuation correction. A correction method, based on correcting one pixel at a time by using density maps and build-up functions, has been d

Traces of copper ions deplete glutathione in human hepatoma cell cultures with low cysteine content

Background: Cell death induced by intracellutar glutathione depletion has been reported to be dependent on the presence of trace amounts of extracellular copper ions. Since little is known about the relationship between glutathione depletion and copper homeostasis, we have in the present study further investigated the role of low amounts of copper ions in glutathione depletion. Methods: Glutathion

Hand function tests and questions on hand symptoms as related to the stockholm workshop scales for diagnosis of hand-arm vibration syndrome.

The severity of hand-arm vibration syndrome (HAVS) is usually graded according to the Stockholm workshop scales. Although the Stockholm workshop scales are regarded the gold standard for assessing the severity of HAVS, they are based primarily on subjective symptoms. The aim of the present study was to explore the agreement between Stockholm workshop scales and the outcome from ten well-defined cl

Light chain shuffling of a high affinity antibody results in a drift in epitope recognition

Human polyclonal and monoclonal antibodies against pathogens and toxins are potentially useful in the treatment of various diseases. A number of human monoclonal antibodies with protective capacity in vitro have been established by conventional hybridoma technology. However, with the development of phage-display technology, the possibility of specifically tailoring antigen-binding properties has i

Contested Belonging : An Indigenous Peoples Struggle for Forest and Identity in Sub-Himalayan

This dissertation deals with the modern predicament of the Rabha or Kocha people, their survival in the forest and their quest for identity. Rabhas are one of India's indigenous or tribal people, and they live in the jungle tracts where the Himalayan mountains meet the plains of Bengal. When the area came under British rule and was converted into tea gardens and reserved forests Rabhas were forced

Neuropeptide Y-2 receptors are involved in enhanced neurogenic vasoconstriction in spontaneously hypertensive rats

1 The present study addressed the role of neuropeptide (NPY) Y-2 receptors in neurogenic contraction of mesenteric resistance arteries from female spontaneously hypertensive rats (SHR). Arteries were suspended in microvascular myographs, electrical field stimulation (EFS) was performed, and protein evaluated by Western blotting and immunohistochemistry. 2 In vasopressin-activated endothelium-intac

Quartic scaling evaluation of canonical scaled opposite spin second-order Moller-Plesset correlation energy using Cholesky decompositions

The scaled opposite spin second-order Moller-Plesset (SOS-MP2) energy expression is reformulated using Cholesky decomposition of the amplitude matrix. The resulting algorithm requires an auxiliary basis or Cholesky representation of the two-electron integrals and shows fourth-order scaling with system size. Based on an analysis of operation counts, we estimate that the present approach is computat

Chlorellestadite in the preheater system of cement kilns as an indicator of HCl formation

The conditions leading to the formation of water-insoluble chlorellestadite, ideal formula (unit cell content) Ca-10(SiO4)(3)O-2, instead of water-soluble KCl and NaCl in Portland cement kiln systems were investigated by quantitative X-ray phase analysis of plant samples, preparation of pure chlorellestadite, and thermodynamic calculations. The results support the view that water-insoluble chlorid

Rural reforms and changes in land management and attitudes: A case study from Inner Mongolia, China

The international science community stresses the importance of the local perspective in the context of dryland degradation. This paper explores changes in management and attitudes in a mixed farming system in northern China, since the introduction of the economic reforms in the early 1980s, and the following changes in land-use rights. The area encompasses a dune landscape scattered with crop-land

Modeling nutrient cycling and sustainable forest growth in a changing world

Popular AbstractSveriges relativa välstånd kan vi till stor del tacka skogen för. Skogen har ända sedan industrialiseringen började ta fart i Sverige bidragit med betydande exportinkomster. För att bevara den inkomstkälla skogen utgör måste vi se till att det skogsbruk som bedrivs är uthålligt och tar hänsyn till såväl ekonomiska som biologiska och sociala aspekter. Skogsproduktionen ska med andraIt took 70-80 years to realize the width of the impact of industrialization on the forest ecosystems since a forest ecosystem is a "slow system" as seen from a human perspective. An anticipated future climate change and increasing carbon dioxide and ozone levels will change the conditions even more with time and the widely used statistical forest growth models will not be applicable anymore.
