Identification and characterization of frontal lobe degeneration - Historical perspective on the development of FTD

This is a historical account of the development of the concept frontotemporal dementia, beginning with our discovery in the late 60s of a simple degenerative form. It was named frontal lobe degeneration of non-Alzheimer type to clearly separate it from the then almost totally dominating diagnosis Alzheimer disease. In the absence of immunohistochemical methods for specific disease markers, we had

Tolerance and efficacy of Omniscan (gadodiamide injection) in MR imaging of the central nervous system

PURPOSE: This Swedish multicenter trial was performed on patients with known or suspected lesions of the CNS for which an MR examination using a contrast medium was indicated. A total of 8 MR centers participated in the study to establish the safety and efficacy of Omniscan (gadodiamide injection) in clinical routine using a standard dose of 0.1 mmol Gd/kg b.w. MATERIAL AND METHODS: Seven hundred

Hydrological Modelling, Topographical Influence and Yield Mapping in Precision Agriculture

The use of topographical data in hydrological and agricultural applications has increased with GPS data availability and the concept of precision agriculture. This thesis investigates the relationships between topography and in one case simulated soil moisture and in the other case yield. The yield was recorded with a new optical sensor, which uses a digital camera to detect objects and records th

Revising the definition of the crustacean seta and setal classification systems based on examinations of the mouthpart setae of seven species of decapods

The crustacean cuticle has numerous projections and some of these projections, the setae, have important mechanical as well as sensory functions. The setae display a wide diversity in their external morphology, which has led to great problems separating setae from other projections in the cuticle and problems in making a consistent classification system. Here, the cuticular projections on the mout

Familial and hormonal risk factors for papillary serous uterine cancer

Objectives: To identify genetic and non-genetic risk factors for papillary serous uterine cancer. Methods: A case-control study was conducted. Case women with papillary serous uterine cancer were compared with two control groups: 1) women with endometrioid uterine cancer and 2) healthy women with no past history of cancer. Cases and controls were matched for age (within two years) and ethnic group

UHV-MOCVD growth of TiO2 on SiOx/Si(111): Interfacial properties reflected in the Si 2p photoemission spectra

Metal-organic chemical vapour deposition growth of titanium oxide on moderately pre-oxidised Si(1 1 1) using the titanium(IV) isopropoxide precursor has been studied for two different growth modes, reaction-limited growth at 300 degrees C and flux-limited growth at 500 degrees C. The interfacial properties have been characterized by monitoring synchrotron radiation excited Si 2p photoemission spec

Charge sampling analogue FIR filter

The finite impulse response (FIR) function of the proposed filter is realised by integrating weighted signal currents in a given time window on a capacitor. The resulting capacitor voltage becomes the filter output, periodically available between integration and reset. In such an FIR filter, the hardware cost is delinked to the number of taps,

Additional transplantation of ex vivo generated megakaryocytic cells after high-dose chemotherapy

The additional transplantation of ex vivo generated hematopoietic (post)-progenitor cells represents a possible approach to ameliorate high-dose chemotherapy induced cytopenia. We investigated the feasibility of the large-scale expansion and transplantation of autologous megakaryocytic cells in four patients with advanced solid tumors. Up to 1,460x10(6) ex vivo generated cells were administered wi

Neural Progenitor Cells in malignancy and injury of the brain. A Trojan Horse fro gliomas?

Popular Abstract in Swedish Gliom är en familj av hjärntumörer som är graderade beroende på hur snabbt och på vilket sätt de växer. Grad IV även kallad glioblastoma multiforme, är den mest elakartade av dessa. Patienter har en medelöverlevnadsprognos på ca 12 månader med behandling, såsom kirurgi, kemo- och strålningsterapi. Tumörerna är heterogena, vilket innebär att celler har flera typer av mutGliomas are neoplasms arising in the central nervous system (CNS), and constitute the most common primary brain tumor. They are classified depending on the grade and morphology, from grade I, pilocytic astrocytoma, to grade IV, glioblastoma multiforme (GBM). Glioblastomas constitute a great challenge in treatment due to their disseminating nature. Classical treatments such as surgery, radiation th

Neuronal replacement from endogenous precursors in the adult brain after stroke.

In the adult brain, new neurons are continuously generated in the subventricular zone and dentate gyrus, but it is unknown whether these neurons can replace those lost following damage or disease. Here we show that stroke, caused by transient middle cerebral artery occlusion in adult rats, leads to a marked increase of cell proliferation in the subventricular zone. Stroke-generated new neurons, as

Solid bolus swallowing in the radiologic evaluation of dysphagia

Patients with dysphagia, heartburn and chest pain are regularly referred for radiologic evaluation of swallowing. The liquid barium swallow has been of great value for the biphasic evaluation of the pharynx and esophagus. Though many patients complain of dysphagia specifically for solids, solid bolus swallow is usually not part of the evaluation. For the present study we therefore included the use

Ten-year probabilities of clinical vertebral fractures according to phalangeal quantitative ultrasonography

The objectives of the present study were to estimate 10-year probabilities of clinical vertebral fractures in women, according to age and bone mineral assessment using phalangeal quantitative ultrasound (QUS). Risks were computed from UK derived data on the incidence of a first symptomatic vertebral fracture and mortality rates for each year of age using Poisson models. The 10-year probability of

Arrest of chlorophyll accumulation prior to anthocyanin formation in Euphorbia pulcherrima

Euphorbia pulcherrima Klotz plants exposed to short days (11 h light/13 h dark) for a period of eight weeks, developed flowers and a red canopy consisting of bracts and few true leaves. Plants maintained for three weeks under short day conditions, failed to produce flower primordia or a red canopy in the following 5 weeks in continuous light. Between the 4th and 5th short day week, the youngest le

Pore structure in supermacroporous polyacrylamide based cryogels

Pore size and thickness of pore walls in macroporous polyacrylamide gels, so-called cryogels (pAAm-cryogels), were controlled by varying the content of monomers in the initial reaction mixture and the cross-linker used. The thickness of pore walls in pAAm-cryogels increased with increasing concentration of monomers in the initial reaction mixture. Pore volume in the supermacroporous pAAm-cryogels

The stable carbon isotope composition of the terrestrial biosphere: Modeling at scales from the leaf to the globe

Global data sets of the stable carbon isotope composition of plant leaves, of CO2 in canopy air, and of CO2 in the background atmosphere were compiled and compared to results of a global vegetation model (BIOME4) that simulated, at these three scales, the magnitude, direction, and timing of fluxes of CO2 and C-13 between the biosphere and the atmosphere. Carbon isotope data on leaves were classifi

The Rate of Isomerisation of Peptidyl-proline Bonds as a Probe for Interactions in the Physiological Denatured State of Chymotrypsin Inhibitor 2

There are four peptidyl-proline bonds in the 64-residue protein chymotrypsin inhibitor 2 (CI2), all of which are in the trans conformation in the native structure. The isomerisation of one or more of these peptidyl-proline bonds to the cis conformation in the denatured state gives rise to heterogeneity, leading to both fast and slow-folding species. The refolding of the fast-folding species, which

An assessment of governmental wind power programmes in Sweden-using a systems approach

The purpose of this paper is to assess the effects, the cost efficiency, and the goal achievement of policy instruments aimed for the development and deployment of wind power in Sweden during the period 1975 to 2000. The paper presents an empirical example of a socio-technical system-based approach for impact assessment, in which changes in the wind power system are described and analysed with res

Complications of video-assisted gastrostomy in children with or without a ventriculoperitoneal shunt

The aim of the study was to test the hypothesis that the presence of a ventriculoperitoneal shunt ( VPS) influences the frequency of postoperative complications after video-assisted gastrostomy ( VAG) in children. When using a power of 80%, a critical value for significance of 5% and an assumed population-based standard deviation of 0.4, it will be required to have a sample size of at least 14 chi
