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 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

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

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

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

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

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 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

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(

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

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

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

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

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

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

PURPOSE: It has been documented that testicular germ cell cancer (TGCC) patients may be at increased risk of developing emotional distress (EMD). Hence, the aim of the present study was to investigate whether EMD is related to the presence of hypogonadism, androgen receptor (AR) polymorphism and/or treatment intensity. PATIENTS AND METHODS: Three to five years after treatment, testosterone and lut

Experiments by Bazant and Pfeiffer on concrete and mortar seem to indicate that crack growth does not necessarily take place under Mode I conditions. In order to investigate the influence of the material, experiments were carried out in PMMA with similar geometry to that used by Bazant and Pfeiffer and a numerical simulation was made assuming Mode I crack growth. The experimental results for PMMA

OBJECTIVE: Vascular inflammation is a key feature of both micro- and macrovascular complications in diabetes. Several lines of evidence have implicated the cytokine tumor necrosis factor (TNF) alpha as an important mediator of inflammation in diabetes. In the present study we evaluated the role of TNF alpha in streptozotocin (STZ)-induced diabetes on vascular inflammation in C57BL/6 wild-type and

The share of North African immigrants in Europe is growing continuously. In this review, we aimed to systematically analyse and describe the literature on weight status and physical activity in North African adults, both in their home country and after immigration to Europe. Existing data on North African residents and on North African immigrants in Europe were analysed by a systematic search on P

The time course of changes in the electrocardiogram as a result of myocardial ischemia induced during prolonged coronary angioplasty has been studied. We have analyzed the electrocardiogram evolution during the occlusion in terms of the Ischemic Changes Sensor, which is a parameter that describes the capacity of different indexes to detect induced changes. Traditional indexes at specific time loca
