Eyeblink conditioning is one of the most popular experimental paradigms for studying the neural mechanisms underlying learning and memory. A key parameter in eyeblink conditioning is the interstimulus interval (ISI), the time between the onset of the conditional stimulus (CS) and the onset of the unconditional stimulus (US). Though previous studies have examined how the ISI affects learning there
Objective: Homecare workers play a pivotal role in palliative care, but research on their experiences is limited. The aim of this study was to describe how homecare workers in Sweden experience their work in palliative homecare. Method: This qualitative study used open-ended interviews with a purposive sample of 15 homecare workers. The data was analysed by means of qualitative content analysis. R
Background: Early menarche and late menopause are important risk factors for breast cancer, but their effects on breast cancer risk in BRCA1 and BRCA2 carriers are unknown. Methods: We assessed breast cancer risk in a large series of 1,187 BRCA1 and 414 BRCA2 carriers from the International BRCA1/2 Carrier Cohort Study. Rate ratios were estimated using a weighted Cox-regression approach. Results:
Analyses of intraspecific genetic structure can promote the conservation of genetic diversity of rare or declining plant species by enabling identification of proper management units. Here we investigate the genetic structure of the annual hemiparasitic herb Rhinanthus angustifolius to evaluate the genetic distinctness of two currently described subspecies and three habitat-related groups of popul
Populations intermediate between the diploid and sexual Sorbus aucuparia and the tetraploid and facultative apomictic Sorbus hybrida are scattered in coastal regions of southern Scandinavia. Our aims were to investigate whether these populations were of local and independent origins, whether they were morphologically and molecularly distinct from each other and whether they could give rise to cons
Purpose: Glioblastoma multiforme (GBM) or astrocytoma grade IV is the most common type of primary brain tumor in adults. In the present study, we investigate the role of the complement system in the glioblastoma situation in an experimental model, since we have previously been able to show a blockade of this system in the glioblastoma setting. Technique and results: A GFP-positive glioblastoma cel
A nonlinear autotuning regulator algorithm is obtained via a direct combination of the Åström-Hägglund algorithm for the linear case [1] with the sinusoidal-input describing function (SIDEF) approach to nonlinear compensator synthesis of Taylor and Strobel [2]. The basic approach for linear autotuning proceeds as follows: a. install a relay with hysteresis in series with the unknown plant to be co
Background Exercise training is recommended to patients with chronic kidney disease (CKD). However, the level of evidence is still low. This randomized controlled trial (RCT) compared two different and self-administered exercise training programs in a representative CKD population. Methods This single centre RCT included 151 non-dialysis dependent CKD patients, irrespective of age and comorbidity.
Objectives: To investigate: (i) changes in sick-leave benefits from 1 year prior to multimodal rehabilitation to 1 and 2 years after rehabilitation; (ii) sex differences in sick leave; and (iii) the impact of policy changes on sick leave. Methods: All patients undergoing multimodal rehabilitation registered in a national pain database for 2007–11 (n?=?7,297) were linked to the Swedish Social
