We apply the Linked Dipole Chain model to hadronic collisions using a modified version of the LDCMC Monte Carlo program. In particular we investigate the effects of multiple scatterings, which in this framework are reformulated in terms of the production of multiple chains of dipoles. We find, among other things, that this way of describing multiple scatterings is less sensitive to the treatment o

The directional stability of an originally straight crack under symmetric remote loading is studied after introduction of an infinitesimal disturbance at one or both tips of the crack. The crack is assumed to grow slowly under vanishing mode II stress intensity factor. Directional stability is defined to prevail if the angle formed by the straight line between the crack tips and the original crack

OBJECTIVE: To investigate possible associations between occupation and hospitalization for systemic lupus erythematosus (SLE) in a nationwide study. METHODS: A nationwide database was constructed in Sweden by linking the Swedish Census to the Hospital Discharge Register to obtain data on all first hospitalizations with a primary or secondary diagnosis of SLE in adults during the study period (19

PURPOSE: Treatment with calcium channel blockers have been associated with increased colon cancer mortality in epidemiologic studies. We examined the potential expression and function of calcium channels in two human colon cancer cell lines. METHODS: Both primary (collected at operation) and commercially-available human colon cancer cell lines were used. The colon cancer cells were incubated with

Intraoperative neuromonitoring (IONM) is widely used during thyroid surgery. During both intermittent and continuous IONM stimulation of the vagus nerve is performed. This has previously been reported to be safe.

BACKGROUND: Prostacyclin is a potent vasodilator, inhibitor of leukocyte adhesion, and platelet aggregation, and has been suggested as therapy for cerebral ischemia. A case of focal traumatic brain lesion that was monitored using intracerebral microdialysis, and bedside analysis and display is reported here. When biochemical signs of cerebral ischemia progressed, i.v. infusion of prostacyclin was

Objectives The aim of this paper was to compare selected indication parameters for patients scheduled for hip and knee replacement at orthopaedic units in Sweden. Methods Swedish orthopaedic clinics performing joint replacement were invited to enrol in the study. The study time was set to 2 years (from June 2006 to June 2008). The study subjects were patients undergoing hip or knee replacement for

Evaluation of prophylactic treatment of haemophilia requires sensitive methods. To design and test a new magnetic resonance imaging (MRI) scale for haemophilic arthropathy, two scales of a combined MRI scoring scheme were merged into a single scale which includes soft tissue and osteochondral subscores. Sixty-one joint MRI's of 46 patients with haemophilia were evaluated by four radiologists using

We present a spatiotemporal analysis of high harmonic generation, showing evidence for the presence of several quantum path contributions to the atomic dipole moment. We show that the harmonic radiation can largely be described as a sum of two fields having a phase proportional to the intensity of the generating field. We compare our results to recent experimental results demonstrating this separa

We report measurements and calculations of the polarization state of high-order harmonics generated by a 790-nm Ti:sapphire laser. The problem of completely characterizing the polarization state of a partially polarized radiation in the XUV range is discussed in detail. The comparison between several gases, xenon, argon and neon, and different orders, from the 17th to the 33rd, shows that the rota

An experimental system has been developed to verify the possibility of detecting flow activity using a technique called ultrasound Doppler vector tomography. A tomography algorithm is used to reconstruct blood flow vector fields using data from computer-controlled ultrasound continuous-wave Doppler scanning equipment. The result is a picture in which the brightness variations represent the reconst

Experience shows that straightforward regulation can be justifiable and effective in some areas (eg, building codes and appliance standards), benefit sharing schemes are often important to ensure stakeholder buy-in (eg, local acceptance for wind power) and public–private partnerships can be imp

Cystatin C and cathepsins could play a role in almost all processes involved in atherosclerotic lesion formation by their degradation of extracellular matrix proteins and apolipoprotein B100, the protein moiety of LDL. Several cysteine cathepsins are upregulated in human lesions accompanied by a decrease in cystatin C, the major inhibitor of cysteine cathepsins. Recent research show that atheroscl

BACKGROUND: Higher operative risks after pneumonectomy for non-small cell lung cancer (NSCLC) have been reported after neoadjuvant chemotherapy or radiotherapy, or both. Patients who underwent pneumonectomy for NSCLC were evaluated for effect of neoadjuvant treatment on mortality and morbidity, especially bronchopleural fistula. METHODS: Between 1996 and 2003, 130 consecutive patients underwent pn

Abstract Background: The metabolic syndrome is regarded as an important risk factor for diabetes mellitus and cardiovascular disease. Metabolic syndrome could be associated with impaired quality of life (QoL). Methods: The Women's Health in the Lund Area (WHILA) project covers 10,766 women born between December 2, 1935, and December 1, 1945, living in the Lund area, of Sweden by December 1, 1995.

The epidemiology of systemic lupus erythematosus (SLE) within a defined region in southern Sweden was studied during the time period 1981-2006. Furthermore, whether the phenotypic expression of SLE changed during the study period was investigated.

Stroke-induced neurogenesis originates from a neural stem cell (NSC) niche in subventricular zone (SVZ). In mice, NSCs are concentrated in a so-called "neurogenic spot" in the lateral angle area of SVZ. We aimed to identify the "neurogenic spot" in the rat SVZ and to characterize the cellular changes in the ependymal cell compartment in this area at different time points after middle cerebral arte

OBJECTIVE: To compare neonatal outcome of blastocyst and cleavage stage embryo transfers after IVF. DESIGN: Register study. PATIENT(S): Treatments reported from all Swedish IVF clinics. INTERVENTION(S): None. SETTING: Births recorded in the Swedish Medical Birth Register after IVF performed, 2002-2006. MAIN OUTCOME MEASURE(S): Some neonatal characteristics were compared in 1,311 infants born after

BACKGROUND: Risk of coronary heart disease (CHD) in cancer patients has not been thoroughly investigated. The aim of the present study was to examine whether there is an association between cancer and first hospitalisation for CHD. METHODS: All individuals in Sweden with a diagnosis of cancer between 1st January 1987 and 31st December 2008 were followed for first hospitalisation for CHD. The refer
