Proposals for standardized Protocols for cytogenetic analyses of acute leukemias, chronic lymphocytic leukemia, chronic myeloid leukemia, chronic myeloproliferative disorders, and myelodysplastic syndromes
The impact of cytogenetic characterization based on chromosome banding analyses and fluorescence in situ hybridization on clinical decision making has increased dramatically during recent years. Therefore, laboratory techniques have to be optimized to provide reliable results for optimal patient care. In addition, quick and correct results save time and money by preventing unnecessary additional d
Gas sensing by tunable multimode diode laser using correlation spectroscopy
A novel method to use multimode diode lasers for gas detection is demonstrated. The relationship between the intensity decay of partially absorbed multiple modes and the target gas concentration is presented. The gas concentration is retrieved by a linear-regression-based procedure applied on simultaneously recorded absorption signals in a dual-beam wavelength-modulation configuration. Signals of
Frontotemporal dementia - a clinically complex diagnosis
Objective To compare the time taken to establish a clinical diagnosis of Frontotemporal dementia (FTD) relative to a diagnosis of early onset Alzheimer's dementia (AD). Methods The data came from 89 patients under the age of 65 years, 52 of whom met the Manchester-Lund criteria for Frontotemporal dementia; 20 of these came from Lund University Hospital in Sweden. The other 32 patients with FTD alo
Center of volume and total heart volume variation in healthy subjects and patients before and after coronary bypass surgery.
BACKGROUND: Total heart volume variation (THVV) and center of volume variation (COVV) likely affects the efficiency of cardiac pumping, but no study has determined COVV of the heart throughout the cardiac cycle or the effect of surgery on THVV in adults. Therefore, the purposes of this study were to determine COVV in healthy adults and patients with cardiac failure due to ischemic heart disease (I
A theoretical basis for estimating quality of life
The three basic paradigms of behaviour science, association, structure, and process, were used to anchor the simulation of new forms of social organization. These have been projected by means of a behaviour, a humanist, and a growth model. The Swedish model was also included as a possible point of reference. This article summarizes the results of two experiments, one on the assessment of quality o

Bacillus agaradhaerens LS-3C cyclodextrin glycosyltransferase: activity and stability features.
Activity and stability characteristics of an alkaline active cyclodextrin glycosyltransferase (CGTase) enzyme from the alkaliphilic Bacillus agaradhaerens LS-3C strain are reported. The enzyme displays unusually high amylolytic activity in relation to the cyclization activity. Disproportionation activity of the CGTase was optimal with maltose as the acceptor substrate. The product of cyclization r
Evidence for a GABA-mediated cerebellar inhibition of the inferior olive in the cat
1. Climbing fibres were activated by peripheral nerve stimulation at 'high' frequencies (greater than 3 Hz) for 15-25 s and then at 0.9 Hz for about 1 min. The high frequency activation induced a post-conditioning inhibition, lasting up to about 1 min, of climbing fibre responses recorded from the cerebellar surface. 2. Electrolytic lesions were made in the superior cerebellar peduncle (brachium c
ATLAS B physics performance update
An update of the B physics performance of the ATLAS experiment is presented. After a short review of B production and decays at LHC, the main features of the ATLAS detector are described, and the present construction status is shown. Physics topics which are presented are: precision measurements, rare decays, and B production. It is shown that despite of recent changes in the trigger strategy and
Political participation and three theories of democracy: A research inventory and agenda
This article proposes an agenda for political participation research aimed at providing empirical answers to questions derived from normative political theory. Based on a threefold distinction between responsive, participatory and deliberative models of democracy, the article first distinguishes three conceptions of political participation: as influencing attempts, as direct decision making, and a
Experimental superradiance and slow-light effects for quantum memories
The effects of high optical depth phenomena, such as superradiance, are investigated in potential quantum memory materials. The results may have relevance for several schemes, including controlled reversible inhomogeneous broadening, atomic frequency combs, and quantum memories based on electromagnetically induced transparency, which are based on using ensembles as storage media. It is shown that
Monitoring health in Sweden. A note on the rationale for working environment regiulations
The quality of the working environment affects the health status of a population. In the absence of government intervention this quality would be determined by market forces, but the market outcome is generally not accepted. Instead public policy attempts to carefully monitor the level of occupational hazards, which are invariably subject to regulation in industrialized countries. However, this st
Antitumor effect of radioactive cisplatin (191Pt) on nude mice
PURPOSE: To investigate the effect of (191)Pt-cisplatin in vivo in terms of the antitumor effect and general toxicity on tumor-bearing nude mice. METHODS AND MATERIALS: Tumor-bearing (human squamous cell carcinoma, AB) nude mice were divided into four groups and given, i.p., physiological saline (controls), cisplatin, (191)Pt-cisplatin (80 MBq/mg), or (191)Pt-cisplatin (160 MBq/mg), respectively.
Anaplastic thyroid carcinoma: three protocols combining doxorubicin, hyperfractionated radiotherapy and surgery.
Patients with anaplastic thyroid carcinoma can rarely be cured, but every effort should be made to prevent death due to suffocation. Between 1984 and 1999, 55 consecutive patients with anaplastic thyroid carcinoma were prospectively treated according to a combined regimen consisting of hyperfractionated radiotherapy, doxorubicin, and when feasible surgery. Radiotherapy was carried out for 5 days a
Treatment of the overactive bladder: possible central nervous system drug targets.
The well-known side effects of antimuscarinic drugs have focused interest on other modalities of treatment of the overactive bladder. To effectively control bladder activity, identification of suitable targets for pharmacologic intervention is necessary. Such targets may be found in the central nervous system (CNS) or peripherally. Several CNS transmitters may modulate voiding, but few drugs with
Response to desmopressin is influenced by the genotype and phenotype in type 1 von Willebrand disease (VWD): results from the European Study MCMDM-1VWD
We have prospectively evaluated the biologic response to desmopressin in 77 patients with type 1 von Willebrand disease (VWD) enrolled within the Molecular and Clinical Markers for the Diagnosis and Management of type 1 VWD project. Complete response to desmopressin was defined as an increase of both ristocetin cofactor activity (VWF:RCo) and factor VIII coagulant activity (FVIII:C) to 50 IU/dL or
A long-term prospective study of optic neuritis: evaluation of risk factors
Eighty-six patients with monosymptomatic optic neuritis of unknown cause were followed prospectively for a median period of 12.9 years. At onset, cerebrospinal fluid (CSF) pleocytosis was present in 46 patients (53%) but oligoclonal immunoglobulin in only 40 (47%) of the patients. The human leukocyte antigen (HLA)-DR2 was present in 45 (52%). Clinically definite multiple sclerosis (MS) was establi
Hypothalamic gene expression following ghrelin therapy to gastrectomized rodents
We investigated whether ghrelin depletion (by gastrectomy surgery) and/or treatment/replacement with the gastric hormone ghrelin alters the expression of key hypothalamic genes involved in energy balance, in a manner consistent with ghrelin's pro-obesity effects. At 2 weeks after surgery mice were treated with ghrelin (12 nmol/mouse/day, sc) or vehicle for 8 weeks. Gastrectomy had little effect on
