Background: Our aim was to study the association between the country of birth and incident end-stage kidney disease (ESKD) in several immigrant groups in Sweden, using individuals born in Sweden or with Swedish-born parents as referents. Methods: A cohort study of first- and second-generation immigrants residing in Sweden between January 1, 1998 and December 31, 2012 was performed. Outcomes were d
Context: The current Common Agricultural Policy (CAP) of the European Union includes three greening measures, which are partly intended to benefit farmland biodiversity. However, the relative biodiversity effects of the greening measures, including joint effects of landscape context, are not well understood. Objectives: We studied the effects of increasing crop diversity, proportions of production
There is limited research that evaluates occupational therapy and lifestyle interventions,especially for mental health service users. This thesis provides increased knowledge and understanding of the processes and factors that led to betterquality of everyday life, engagement in meaningful activities, and balance forparticipants who took part in the Balancing Everyday Life (BEL) intervention.BEL w
Metabolic syndrome and diabetes impact brain function and metabolism. While it is well established that rodents exposed to diets rich in saturated fat develop brain dysfunction, contrasting results abound in the literature, likely as result of exposure to different high-fat diet (HFD) compositions and for varied periods of time. In the present study, we investigated alterations of hippocampal-depe
PURPOSE: Determine the feasibility of 1 H-[13 C] MRS in the mouse hypothalamus using a 14.1T magnet.METHODS: We optimized the design of a 1 H-[13 C] surface coil to maximize the signal-to-noise ratio of 1 H-[13 C] MRS in the mouse hypothalamus. With enhanced signal, 13 C accumulation in glucose metabolites was measured in a 8.7 µL voxel in the hypothalamus of 5 healthy mice during the continuous a
Diabetes affects the morphology and plasticity of the hippocampus, and leads to learning and memory deficits. Caffeine has been proposed to prevent memory impairment upon multiple chronic disorders with neurological involvement. We tested whether long-term caffeine consumption prevents type 2 diabetes (T2D)-induced spatial memory impairment and hippocampal alterations, including synaptic degenerat
From epidemiological studies it is known that diabetes patients display increased risk of developing dementia. Moreover, cognitive impairment and Alzheimer's disease (AD) are also accompanied by impaired glucose homeostasis and insulin signalling. Although there is plenty of evidence for a connection between insulin-resistant diabetes and AD, definitive linking mechanisms remain elusive. Cerebrova
Different presynaptic neuromodulation systems have been explored as possible targets to manage neurodegenerative diseases. However, most studies used young adult animals whereas neurodegenerative diseases are prevalent in the elderly. Thus, we now explored by Western blot analysis how the density of different presynaptic markers and receptors changes with aging in rat hippocampal synaptosomes (pur
In the hippocampus, impaired neurophysiology, compromised neurogenesis, and eventually apoptosis accompany cognitive deficits in insulinopenic (type-1) diabetes (T1D). The underlying pathological mechanisms remain to be defined. The hippocampus has a high density of the cannabinoid type 1 receptor (CB(1)R), which has been shown to control several brain functions affected by diabetes, such as synap
Adenosine A(1) and A(2A) receptors are neuromodulatory systems that can control mnemonic behavior, which is modified by diabetes. Since the density of these adenosine receptors can change upon chronic noxious brain conditions, we now tested if the density of A(1) and A(2A) receptors was modified in the hippocampus of streptozotocin-induced diabetic rats. The binding density of the selective A(1) r
Pridopidine is a small molecule in clinical development for the treatment of Huntington’s disease. It was recently found to have high binding affinity to the sigma-1 receptor, a chaperone protein involved in cellular defense mechanisms and neuroplasticity. Here, we have evaluated the neuroprotective and neurorestorative effects of pridopidine in a unilateral 6-hydroxydopamine (6-OHDA) lesion model
Diabetes is associated with decrements in cognitive function and with abnormalities in brain morphology. In addition, alterations of metabolism have been reported in the diabetic brain. Magnetic Resonance Spectroscopy (MRS) is a non-invasive technique that can be employed to determine the concentration of metabolites in a fully non-invasive manner under normal physiological conditions. The present
Cerebral glucose homeostasis is maintained by the equilibrium between glucose transport across the blood-brain-barrier (BBB), which occurs through facilitative carriers, and glucose consumption mainly initiated by hexokinase phosphorylation. Glucose concentrations can be quantified non invasively by nuclear magnetic resonance (NMR) spectroscopy and such measurements, through appropriate mathematic
The aim of the study was to identify changes in agricultural practices and periods of agricultural expansion and regression during the last 1,300 years in the South-Swedish Uplands. Sediments from the small lake of Skärpingsgölen (1.2 ha) were used to quantify land-cover at a local scale (c. 1 km radius) in 50-year intervals based on pollen analysis and the LOVE model (Local Vegetation Estimates).
RATIONALE:Hypomotor seizures (characterized by diminished behavioral activity with indeterminate level of consciousness) have been identified as an important seizure type in infants. Our goal was to further investigate the clinical and EEG features of hypomotor seizures.METHODS:We retrospectively reviewed 110 hypomotor seizures from 34 patients recorded with video-EEG.RESULTS:Twenty-seven patients
This reflection, based on a keynote address to celebrate the fortieth anniversary of Disasters on 14 September 2017, begins by considering some of the prevailing assumptions that existed at the time of the journal's creation. Next is a summary of significant milestones during the past 40 years, covering major global trends, changing disaster impacts, and key developments in disaster risk managemen
We report on X-ray scattering measurements of helical poly[9,9-bis(2-ethylhexyl)-fluorene-2,7-diyl] by mapping the sample with 10 μm spatial resolution from 0.3 GPa to 36 GPa. We follow the strongest 00l reflection, which moves toward higher scattering angles with pressure indicating planarization of helical polyfluorene. Lateral inhomogeneity is increased for >10 GPa concomitant with the solidifi
Background: The risks of thromboembolic and hemorrhagic events in patients with atrial fibrillation both increase with age; therefore, net clinical benefit analyses of anticoagulant treatments in the elderly population are crucial to guide treatment. We evaluated the 1-year clinical outcomes with non-vitamin-K antagonist and vitamin K antagonist oral anticoagulants (NOACs vs VKAs) in elderly (≥75
