Accumulating evidence demonstrates an association between dense infiltration of lymphocytes and prognosis in colorectal cancer (CRC), but whether this prognostic impact differs by tumour location remains unknown. This study investigated the prognostic impact of cytotoxic and regulatory T cells in CRC, with particular reference to the anatomical subsite of the primary tumour. The density of CD3+, C
From the 6th to the 9th of November 2016, in the meeting hall of Centro Nacional de Aceleradores(University of Seville, Seville, Spain) took place the “II International Conference onRadioecological Concentration Processes (50 years later)” under the joint organization of theUniversities of Seville (Spain) and Gothenburg (Sweden). With this event, the organization try tocommemorate the fifty years
Background: Long-term intensive training leads to morphological and mechanical changes in the heart generally known as "athlete's heart". Previous studies have suggested that the diastolic and systolic function of the ventricles is unaltered in athletes compared to sedentary. The purpose of this study was to investigate myocardial performance index (MPI) by pulsed wave Doppler (PWD) and by tissue
Background Worse outcomes have been noted in patients with multiple primary melanomas (MPMs) than in patients with single primary melanomas. Objective We investigated how family history of melanoma and germline CDKN2A mutation status of MPM patients affects risks of developing subsequent melanomas and other cancers and survival outcomes. Methods Comprehensive data on cancer diagnoses and deaths of
Sapflow density was measured in six stands in a boreal forest in central Sweden, to assess its dependence on soil moisture and stand characteristics. The stands were mixed and pure Scots pine and Norway spruce stands, which were between 34 and 105 years old. Sapflow was measured in 12 trees per stand using the Granier method during two contrasting growing seasons; one warm and dry and one wet and
Several authors have reported promising results with vacuum-assisted closure therapy in poststernotomy mediastinitis. The aim of this study was to investigate the hemodynamic outcome following the application of six negative pressures on an open sternotomy wound. Six 70-kg pigs underwent median sternotomy followed by vacuum-assisted closure therapy. Six negative pressures (-50, -75, -100, -125, -1
BACKGROUND: Activated mast cells can produce and release a number of inflammatory mediators involved in the pathophysiology of acute conditions. The aim of the present study was to evaluate the role of activated tissue mast cells in the pathogenesis of multiple organ dysfunction syndrome following acute pancreatitis (AP). METHODS: AP was induced by the intraductal infusion of 5 per cent sodium tau
The combination of environmental chamber exposure and bronchoalveolar lavage (BAL) was used to study the effects of the common air pollutant nitrogen dioxide (NO2). Eighteen healthy nonsmokers were exposed to NO2 during 20 min in an exposure chamber during light bicycle ergometer work. All subjects were examined with BAL at least 3 wks before exposure, as a reference. The subjects were re-examined
A recently developed ultrasound phase-locked echo-tracking system makes it possible to measure non-invasive pulsatile vessel diameter changes, and, in combination with blood-pressure measurement, to calculate pressure strain elastic modulus (Ep) and stiffness (beta). The reproducibility in measurements of pulsatile diameter changes with this system was evaluated. Also the precision of indirect blo
Background: Local pain at the site of intravenous (iv) injection of propofol remains a considerable problem in clinical anaesthesiology, and particularly so in infants. The aim of the present study was to compare the influence of two different emulsions of propofol on local pain following iv administration. Methods: Eighty adult patients (ASA I-II) scheduled for ear-nose-throat or plastic surgery
Leaching of dissolved organic carbon (DOC) from the forest floor and transport in soil solution into the mineral soil are important for carbon cycling in boreal forest ecosystems. We examined DOC concentrations in bulk deposition, throughfall and in soil solutions collected under the O and B horizons in three Norway spruce stands along a climatic gradient in Sweden. Mean annual temperature for the
The genetic variation of Duddingtonia flagrans, which has become a promising biocontrol agent of animal parasitic nematodes, was investigated in a worldwide collection of 22 isolates. We analysed the sequence variation in four nuclear genes, tubA (beta-tubulin), CMD1 (calmodulin), EF1alpha (translation elongation factor 1alpha), and PII (extracellular serine protease). 1428 aligned base pairs (bp)
The possibility that nitric oxide synthase (NOS) inhibitors influence dynorphin immunoreactivity following hyperthermia was examined in a rat model using a pharmacological approach. Previous reports from our laboratory show that hyperthermia induces an upregulation of NOS in several brain regions that seems to be instrumental in causing cell injury. Recent reports suggest that nitric oxide (NO) ca
The southern slopes of the mountain ridge Kolmarden along the northern border of the province Ostergotland ill south-eastern Sweden have a very rich flora and varied geomorphology. Several rare and locally endemic microspecies of Hieracium have been described or reported from the area but no hieraciologist has visited the region since c. 1930. In 2004, the present author walked c. 50 km in this ar
Ab initio calculations of low-lying electronic states of CrH are presented, including potential energies, dipole and transition dipole moment (TDM) functions, and radiative lifetimes for X (6)Sigma(+), A (6)Sigma(+), 3 (6)Sigma(+), 1 (6)Pi, 2 (6)Pi, 3 (6)Pi, and (6)Delta. Calculation of dynamic correlation effects was performed using the multistate complete active space second-order perturbation m
Abstract in Spanish Antecedentes: Las pruebas cutáneas con determinantes mayores y menores de la penicilina se utilizan de forma habitual para el diagnóstico de reacciones de hipersensibilidad inmediata a los antibióticos betalactámicos. Estos extractos diagnósticos han sido recientemente retirados del mercado europeo. Objetivo: Estudio de una nueva marca de determinantes para el diagnóstico de reBACKGROUND: Skin testing with major and minor determinants of benzylpenicillin is recommended standard practice for the evaluation of patients with immediate hypersensitivity reactions to beta-lactams. However, commercial reagents for this purpose were recently dropped from the European market. OBJECTIVE: In the present study, we assessed a new brand of reagents for use in skin testing in patients
Stroke is a neurodegenerative disorder and the leading cause of disability in adult humans. Treatments to support efficient recovery in stroke patients are lacking. Several studies have demonstrated the ability of grafted neural stem cells (NSCs) to partly improve impaired neurological functions in stroke-subjected animals. Recently, we reported that NSCs from human fetal striatum and cortex exhib
The immunosuppressant cyclosporin A (CsA) has been shown to have neuroprotective action. The inhibition of both calcineurin activation and mitochondrial permeability transition pore (mtPTP) opening are considered the primary neuroprotective mechanisms of CsA. Here we have evaluated the effect of CsA on significantly reducing infarct size induced by transient middle cerebral artery occlusion (MCAO)
