A spinel-type catalyst of the composition Fe(2.50(1-z/3))V(0.20(1-z/3))Mo(0.30(1-z/3))square(z)O(4), where z is the number of cation vacancies (El), was prepared under reducing atmosphere. From the reduced sample a number of preoxidized samples were made by TPO treatment of the reduced material to different end temperatures ranging from 150 to 450 degrees C. XRD shows that the spinel-type structur
During the last decades a striking decline has been observed for wild bees throughout central and north-western Europe, including Sweden. in an area of 64 km' in the parish of Stenbrohult, southern Smaland Andrena hattorfiana, Andrena humilis, Nomada armata and Panurgus hanksianus were studied (in Sweden red-listed as VU, EN, EN and VU). We present occurrence patterns in relation to habitat types
BACKGROUND: Degranulation of eosinophils in target tissues is considered a key pathogenic event in major chronic eosinophilic diseases. However, because of a lack of appropriate methods, little is known about degranulation of eosinophils in common eosinophilic diseases. METHODS: Using transmission electron microscopic (TEM) analysis, a novel approach has been devised and validated to quantify eosi
Object. Arterial vasospasm is the most common cause of delayed ischemic neurological deficits (DINDs) and one of the major causes of disability following subarachnoid hemorrhage (SAH). Current management of vasospasm involves intravascular volume expansion and hemodynamic augmentation with the goal of increasing cerebral blood flow (CBF). The purpose of this study was to examine the effects of vol
A "complex salt" of cetyltrimethylammonium (CTA(+)) with short (30 repeating units) polyacrylate (PA(-)) counterions has been synthesized. The phase diagrams of its aqueous mixtures with either the surfactant cetyltrimethylammonium acetate (CTAAc), or the polyelectrolyte NaPA, have been studied by visual inspection through crossed polarizers and by small-angle X-ray scattering. Both of the ternary
Bioelectrocatalytic reduction of H2O2 catalysed by lignin peroxidase from Phanerochaete chrysosporium (LiP) was studied with LiP-modified graphite electrodes to elucidate the ability of UP to electro-enzymatically oxidise phenols, catechols, as well as veratryl alcohol (VA) and some other high-redox-potential lignin model compounds (LMC). Flow-through amperometric experiments performed at +0.1 V v
Background: There have been reports both supporting and refuting an inverse relationship between hip fracture and hip osteoarthritis (OA). We explore this relationship using a case-control study design. Methods: Exclusion criteria were previous hip fracture (same side or contralateral side), age younger than 60 years, foreign nationality, pathological fracture, rheumatoid arthritis and cases were
It is known that warm and humid environment reduces human physical performance. The present study examined whether the use of an ice-vest in such conditions can improve cycling performance. Seven participants cycled with consecutive, non-stop, 10-minute cycles of nine minutes at 60% of their (V) over dot O-2 max punctuated by a one-minute sprint at 80% (V) over dot O-2 max. The cycling protocol wa
The very young Wabar craters formed by impact of an iron meteorite and are known to the scientific community since 1933. We describe field observations made during a visit to the Wabar impact site, provide analytical data on the material collected, and combine these data with poorly known information discovered during the recovery of the largest meteorites. During our visit in March 2008, only two
Molecularly imprinted polymers (MIPs) targeting quercetin were prepared from 4-vinylpyridine and ethylene dimethacrylate (EDMA) under various solvent systems with the aim to form MIPs with high recognition for the quercetin molecule in aqueous systems at high temperature. A MIP prepared from the three-component solvent mixture of THF/H2O/MeOH showed potential in its application for the determinati
Background: To estimate cardiovascular disease (CVD) mortality in relation to obesity and gender. Methods: Data from 11 prospective cohorts from four European countries including 23 629 men and 21 965 women, aged 24 to 99 years, with a median follow-up of 7.9 years were analyzed. Hazards ratios (HR) for CVD mortality in relation to baseline body mass index (BMI), waist circumference (WC), waist-to
Background Chronic congestive heart failure is a complex condition that leads to dysfunction in the peripheral microcirculation. We have previously shown that vascular reactivity is reduced with increasing age. In this study, we examined a group of very old patients with severe chronic heart failure to test the hypothesis that vascular function is further compromised by a combination of heart fail
Popular Abstract in Swedish Inledning I detta avhandlingsarbete studeras Mycoplasma pneumoniae (MP) och influensa virus ur olika perspektiv. Dessa två smittämnen orsakar båda årliga utbrott med luftvägsinfektioner som ibland blir omfattande epidemier. I båda fallen kan symptomen variera från lätta förkylningsbesvär till mycket svåra, ibland livshotande lunginflammationer. Infektion med MycoplasmaDiagnostic tests based on nucleic acid amplification have become available for Mycoplasma pneumoniae (MP) and influenza viruses. Here, an MP PCR test detected 100% of infections during the first three symptomatic weeks, whereas classical serology detected 21% week 1, 56% week 2, and 100% week 3. Positive PCR results were uncommon in healthy individuals. Levels of MP DNA were significantly higher i
Objectives: Tetrachloroethylene is the dominant solvent used in dry cleaning worldwide and many workers are potentially exposed. We report here on results of 1296 measurements of tetrachloroethylene undertaken in Nordic dry cleaning shops 1947–2001. Methods: We searched documents and files in the Nordic institutes of occupational health for air measurements of tetrachloroethylene. Repeated measur
Background Long-term outcome after hematopoietic stem cell transplantation including late transplant-related events is of increasing interest. The aim of this study was to evaluate the incidence of cardiovascular events after allogeneic HSCT and to search for their risk factors. Design and Methods This is a retrospective mutlicenter European Group of Blood and Marrow Transplantation (EBMT) analysi
Electrode grounding resistance is a major factor affecting measurement quality in electric resistivity tomography (ERT) measurements for cryospheric applications. Still, little information is available on grounding resistances in the geophysical literature, mainly because it is difficult to measure. The focus-one protocol is a new method for estimating single electrode grounding resistances by mea
Anti-neutrophil cytoplasmic antibodies (ANCAs) have a pathogenic role in ANCA-associated vasculitis. The origin of ANCAs and anti-glomerular basement membrane (GBM) antibodies, however, is unknown. In this study, we determined whether natural autoantibodies against myeloperoxidase (MPO), proteinase 3 (PR3), and GBM were present in each of 10 healthy Chinese and Swedish individuals, negative for al

Background: There is controversy regarding the influence of ketamine and its enantiomers on cerebral haemodynamics at increased intracranial pressure (ICP). This study was designed to compare cerebrovascular responses, with particular respect to ICP, to bolus injections of racemic, S(+)- and R(-)-ketamine in an experimental model of intracranial hypertension. Methods: Nine pigs were anaesthetised
