A deviation display method for visualising data in mobile gamma-ray spectrometry.
A real time visualisation method, to be used in mobile gamma-spectrometric search operations using standard detector systems is presented. The new method, called deviation display, uses a modified waterfall display to present relative changes in spectral data over energy and time. Using unshielded (137)Cs and (241)Am point sources and different natural background environments, the behaviour of the
Role of platelets in experimental acute pancreatitis.
BACKGROUND:: Platelets not only control thrombosis and haemostasis but may also regulate inflammatory processes. Acute pancreatitis (AP) is characterized by changes in both coagulation and proinflammatory activities. The role of platelets in AP is not yet known. METHODS:: AP was induced in C57BL/6 mice by repeated caerulein administration (50 µg/kg intraperitoneally). Mice received a platelet-depl
Do discordant cancers share familial susceptibility?
AIMS: Cancer syndromes manifest at many sites albeit with variable penetrance. Genome-wide association (GWA) studies have identified susceptibility loci shared by many types of cancer. Yet, a population level search for shared susceptibility between discordant cancers has been hampered because of lacking population sizes. METHODS: Over 1.1million patients in the nation-wide Swedish Family-Cancer D
Long-term exposure to IL-1beta enhances Toll-IL-1 receptor-mediated inflammatory signaling in murine airway hyperresponsiveness.
Toll-interleukin-1 (Toll-IL-1) receptor signaling may play a key role in the development of airway hyperreactivity (AHR) and chronic airway inflammatory diseases such as asthma. Previously, we have demonstrated that pro-inflammatory cytokines, tumor necrosis factor-alpha (TNF-alpha) and interleukin-1beta (IL-1beta), induce AHR. However, the underlying intracellular signaling mechanisms that lead t
The Moraxella IgD-binding protein MID/Hag is an oligomeric autotransporter.
The immunoglobulin D (IgD)-binding protein MID/Hag of the human respiratory pathogen Moraxella catarrhalis is an outer membrane protein of approximately 200kDa belonging to the autotransporter family. MID also functions as an adhesin and hemagglutinin. In the present paper, the ultrastructure of MID was mapped. Using a series of Escherichia coli transformants, the last 210 aa of the C-terminal reg
Using tabletop exercises to learn about crisis: empirical evidence
Tabletop exercises are often used for learning purposes in the area of crisis management, yet their potential for this is far from clear. The study examines the learning outcomes achieved by a group of persons taking part in tabletop exercises in which they assess the crisis management capabilities of the organisation to which they belong and suggest possible improvements. Interviews with the part
A 5 year prospective study of patient-relevant outcomes after total knee replacement.
OBJECTIVE: To prospectively describe self-reported outcomes up to 5 years after total knee replacement (TKR) in Osteoarthritis (OA) and to study which patient-relevant factors may predict outcomes for pain and physical function (PF). METHODS: 102 consecutive patients with knee OA, 63 women and 39 men, mean age 71 (51-86) assigned for TKR at the Department of Orthopaedics at Lund University Hospita
Flow cytometry-based identification of immature myeloerythroid development.
Precursor cells of the myeloerythroid cell lineages give rise to mature cells of the granulocyte, monocyte, erythroid, and/or thrombocytic lineages. High-resolution profiling of the developmental stages, from hematopoietic stem cells to mature progeny, is important to study and understand the underlying mechanisms that guide various cell fate decisions. In addition, this approach provides greater
Development of the 3-SET 4P questionnaire for evaluating former ICU patients' physical and psychosocial problems over time: A pilot study.
BACKGROUND: Current studies reveal a lack of consensus for the evaluation of physical and psychosocial problems after ICU stay and their changes over time. OBJECTIVES: The aim was to develop and evaluate the validity and reliability of a questionnaire for assessing physical and psychosocial problems over time for patients following ICU recovery. PATIENTS: Thirty-nine patients completed the questio
Stereoacuity and intraocular surgical skill: Effect of stereoacuity level on virtual reality intraocular surgical performance.
PURPOSE: To evaluate the effect of stereoacuity on various intraocular surgical skills in inexperienced medical students using a virtual reality intraocular surgical simulator. SETTING: Department of Clinical Sciences, Malmö: Ophthalmology, Skåne University Hospital, Malmö, Sweden. DESIGN: Comparative case series. METHODS: Ninth-semester medical students performed 1 iteration on each of the fol
Coping strategies in daily occupations 3 months after a severe or major hand injury.
Coping strategies used in performing daily occupations 3 months after a severe or major hand injury were explored. A semi-structured interview was performed with 13 participants with hand injuries based on Hand Injury Severity Scoring System and analysed using content analysis. Six groups of strategies were identified: 'Changing performance of daily occupations', 'Actively processing trauma experi
Cockroach optomotor responses below single photon level
Reliable vision in dim light depends on the efficient capture of photons. Moreover, visually guided behaviour requires reliable signals from the photoreceptors to generate appropriate motor reactions. Here, we show that at behavioural low-light threshold, cockroach photoreceptors respond to moving gratings with single-photon absorption events known as 'quantum bumps' at or below the rate of 0.1 s(
Developments in macromolecular drug delivery.
Macromolecular drugs hold great promise as novel therapeutics of several major disorders, such as cancer and cardiovascular disease. However, their use is limited by lack of efficient, safe, and specific delivery strategies. Successful development of such strategies requires interdisciplinary collaborations involving researchers with expertise on, e.g., polymer chemistry, cell biology, nanotechnol
Does the Current Constraints in Funding Promote Failure in Humanitarian Supply Chains?
Traditionally, most funding is made available when a disaster occurs. Disaster re-sponse is the implementation of what humanitarian actors did (or didn't do) in pre-paredness for any intervention. Based on a case study of a logistics change in the International Federation of Red Cross Red Crescent Society, this paper discusses how more funding of preparedness can radically improve the speed and qu
"I need to lead my own life in any case"-A study of patients in dialysis with or without a partner.
OBJECTIVE: To elicit psychological and psychosocial problems existing in patients in dialysis and their partners, its being felt that the diversity involved has important implications for how service in dialysis units is delivered to patients and their partners. METHODS: The results of a series of interviews of 39 patients in dialysis and 21 partners of theirs, each interview individual, concernin
Vacuum-assisted closure therapy for deep sternal wound infections: the impact of learning curve on survival and predictors for late mortality.
The aim of this study was to evaluate the possible learning curve effects on survival during the introduction of vacuum-assisted closure (VAC) therapy in patients with deep sternal wound infection (DSWI). Furthermore, predictors of late mortality were analysed and causes of late death were examined. Fifty-three patients (early Group, n = 26, January 1999 to July 2001 versus late group, n = 27, Aug
Risk of mental disorders in subjects with intellectual disability in the Lundby cohort 1947-97.
The Lundby Study is a prospective cohort study, which has followed a Swedish unselected community sample between 1 July 1947 and 1 July 1997. The aim was to study the risks of mental morbidity and different DSM-IV disorders in subjects with intellectual disability (ID) in the Lundby cohort between 1 July 1947 to 30 June 1997. The diagnosis of ID was re-evaluated according to DSM-IV in subjects who
HDL Stimulates apoM Secretion.
Apolipoprotein M (apoM) in human plasma is mainly associated with HDL. A retained signal peptide anchors apoM to the lipoproteins. To investigate the role of the signal peptide in the transfer of apoM from the synthesizing cell to the lipoproteins, wildtype apoM cDNA and the Q(22)A mutant, introducing a signal peptidase cleavage site, were used to stably transfect HEK293 cells, which intrinsically
Mice Lacking 12/15-Lipoxygenase have Attenuated Airway Allergic Inflammation and Remodeling.
Arachidonate 15-lipoxygenase (LO)-1 has been implicated in allergic inflammation and asthma. The overall effect of 15-LO in allergic inflammation in vivo is, however, unclear. This study investigates systemic allergen sensitization and local allergic airway inflammation and remodeling in mice lacking the murine 12/15-LO, the ortholog to human 15-LO-1. Upon systemic sensitization with intraperitone
