It is speculated that virtual environments (VE) might be used as a training tool in brain injury rehabilitation. The rehabilitation process often involves practicing so-called instrumental activities of daily living (IADL), such as shopping, cooking, and using a telephone. If a brain injury patient is to practice such activities in a VE, the patient must be able to navigate the viewpoint and inter
Many recent studies have found genetically differentiated populations in microorganisms despite potentially high dispersal. We designed a study to specifically examine the importance of physical dispersal barriers, i.e. geographic distance and lack of hydrological connectivity, in restricting gene flow and enhancing divergence in limnic microorganisms. We focused on the nuisance microalga Gonyosto
A heterogeneous distribution of radionuclides emitting low-energy electrons in the testicles may result in a significant difference between an absorbed dose to the radiosensitive spermatogonia and the mean absorbed dose to the whole testis. This study focused on absorbed dose distribution in patients at a finer scale than normally available in clinical dosimetry, which was accomplished by combinin
The perennial herbaceous crop Arundo donax is a potential feedstock for second-generation bioethanol production. In the present work, two different process options were investigated for the conversion of two differently steam-pretreated batches of A. donax. The pretreated raw material was converted to ethanol with a xylose-consuming Saccharomyces cerevisiae strain, VTT C-10880, by applying either
The extent to which a system of services is in tune with the needs of the population can be expressed in terms of target efficiency, which includes horizontal target efficiency - the extent to which those deemed to need a service receive it - and vertical target efficiency - the corresponding extent to which those who receive a service actually need it. Vertical efficiency can be measured by looki
SWENOTECA has since 1998 offered patients with clinical stage I (CS I) nonseminoma, adjuvant chemotherapy with one course of bleomycin, etoposide and cisplatin (BEP). The aim has been to reduce the risk of relapse, sparing patients the need of toxic salvage treatment. Initial results on 312 patients treated with one course of adjuvant BEP, with a median follow-up of 4.5 years, have been previously
Purpose To determine if anti-retroviral therapy (ART) in HIV-infected patients is associated with an increased risk for development of abdominal wall hernia. Methods A cohort study of 1072 HIV-infected patients in Sweden. Information was collected by questionnaires to patients and treating physicians, chart reviews by study physicians and regular blood tests for metabolic disorders. Adjusted relat
The opacity of the Earth to incident ultrahigh energy neutrinos is directly connected with the behavior of the neutrino-nucleon (sigma(nu N)) cross sections in a kinematic range utterly unexplored. In this work we investigate how the uncertainties in sigma(nu N) due the different QCD dynamic models modify the neutrino absorption while they travel across the Earth. In particular, we compare the pre
We have studied the transverse-momentum (p(T)) dependence of the inclusive J/psi production in p-Pb collisions at root s(NN) = 5.02 TeV, in three center-of-mass rapidity (y(cms)) regions, down to zero p(T). Results in the forward and backward rapidity ranges (2.03 < y(cms) < 3.53 and -4.46 < y(cms) < -2.96) are obtained by studying the J/psi decay to mu(+)mu(-), while the mid-rapidity region (-1.3
Animals display remarkable individual variation in their capacity to mount immune responses against novel antigens. According to the life-history theory, this variation is caused by the costs of immune responses to the hosts. We studied one of such potential costs, depletion of somatic resources in wintering wild-caught captive passerines, the great tits (Parus major) by immune challenging the bir
Since the fall of the communism, many heated debates about the past took place in Poland, with the stormiest among them concerning not the communist crimes, as one might expect, but the Polish-Jewish relations during the Holocaust and in the immediate post-war years. The most discussed history books in post-communist Poland - “Neighbours” (2000) and “Fear” (2008) by Jan T. Gross dealt with anti-Se
Humidified gas turbines (HGT) offer the attractive possibility of increasing plant efficiency without the cost of an additional steam turbine as is the case for a combined gas-steam cycle. In addition to efficiency gains, adding steam into the combustion process reduces NOx emissions. It increases the specific heat capacity (hence, lowering possible temperature peaks) and reduces the oxygen concen
Clinical pathways aim to ensure that individuals receive appropriate evidence-based care and interventions, with the Liverpool Care Pathway for the Dying Patient focusing on end of life. However, controlled studies of the Liverpool Care Pathway for the Dying Patient, particularly outside of cancer settings, are lacking.
In a north European context, identifying invasive species is far from trivial because the vegetation has been influenced by human activities for thousands of years. New species have immigrated continuously since the end of the last glaciation, both spontaneously and through direct or indirect help by man. Still, newly immigrated species may be problematic in a nature conservation context and may h
Current European Association of Urology guidelines state that a PSA≥100 ng/ml at diagnosis indicates metastatic disease. The aim of the present study was to examine the association between PSA values ≥100 ng/ml at diagnosis, distant metastasis and prostate cancer-specific survival.
The aim of this study was to use the Swedish National Registry of Urinary Bladder Cancer (SNRUBC) to investigate changes in patient and tumour characteristics, management and survival in bladder cancer cases over a period of 15 years.
Background: Social and lifestyle influences on age-related changes in body morphology are complex because lifestyle and physiological response to social stress can affect body fat differently. Objective: We examined the associations of socioeconomic status (SES) and lifestyle factors with body mass index (BMI) and waist circumference (WC) in middle-aged and elderly European men. Design and setting
To explore whether quantitative, three-dimensional measurements of meniscal position and size are associated with knee pain using a within-person, between-knee study design. We studied 53 subjects (19 men, 34 women) from the Osteoarthritis Initiative, with identical radiographic OA grades in both knees, but frequent pain in one and no pain in the other knee. The tibial plateau and menisci were ana
Heart rate corrected QT (QTc) interval prolongation is a risk factor associated with increased mortality. Hyperbaric oxygen therapy (HBO) has previously been shown to have acute beneficial effects on QTc dispersion. The aim of this study was to evaluate long-term effects of HBO on QTc time in diabetic patients with hard-to-heal foot ulcers.
BACKGROUND: Lu-177-(DOTAO,Tyr3) octreotate is a new treatment modality for disseminated neuroendocrine tumors. According to a consensus protocol, the calculated maximally tolerated absorbed dose to the kidney should not exceed 27 Gy. In commonly used dosimetry methods, planar imaging is used for determination of the residence time, whereas the kidney mass is determined from a computed tomography (
