Alzheimer’s Disease (AD) is a devastating neurodegenerative disease associated with massive neuronal cell death during its pathology. The involvement of the amyloid β 42 (Aβ42) peptideand its role in neurotoxicity is now well established. It is known that the production of oligomers during the aggregation of Aβ42 into highly ordered fibrils is responsible for neuronal cell death. However, the effo
The chaperone DNAJB6b delays amyloid formation by suppressing the nucleation of amyloid fibrils and increases the solubility of amyloid-prone proteins. These dual effects on kinetics and equilibrium are related to the unusually high chemical potential of DNAJB6b in solution. As a consequence, the chaperone alone forms highly polydisperse oligomers, whereas in a mixture with an amyloid-forming prot
Background: Essential proteins play an important role in the process of life, which can be identified by experimental methods and computational approaches. Experimental approaches to identify essential proteins are of high accuracy but with the limitation of time and resource-consuming. Objective: Herein, we present a computational model (PEPRF) to identify essential proteins based on machine lear
Mesenchymal cells are important components of specified niches in the lung, and can mediate a wide range of processes including tissue regeneration and repair. Dysregulation of these processes can lead to improper remodeling of tissue as observed in several lung diseases. The mesenchymal cells responsible remain poorly described, partially due to the heterogenic nature of the mesenchymal compartme
α-synuclein is an intrinsically disordered protein implicated in synaptic vesicle trafficking at the synapse. Accumulation of α-synuclein in the form of amyloid deposits coincides with the loss of dopaminergic neurons in Parkinsons disease. These deposits, referred to as Lewy Bodies, have been shown to contain membrane lipids together with the α-synuclein amyloid fibrils and other proteins. It was
Northern forest soils are a major carbon (C) reservoir of global importance. To estimate how the C balance in these soils will change, the roles of tree roots and soil microbes in C balance should first be decoupled. This study determined how the activity of heterotrophs and tree roots together with root-associated microbes in the rhizosphere varies in coniferous forest soils in boreal, hemiboreal
Several publications describing high-resolution structures of amyloid-β (Aβ) and other fibrils have demonstrated that magic-angle spinning (MAS) NMR spectroscopy is an ideal tool for studying amyloids at atomic resolution. Nonetheless, MAS NMR suffers from low sensitivity, requiring relatively large amounts of samples and extensive signal acquisition periods, which in turn limits the questions tha
Objective The prevalence of type 2 diabetes (T2D) among Iraqi immigrants to Sweden is high and partly related to sedentary physical activity and calorie dense food. The aim of the present study was to explore perceptions, experiences and barriers concerning lifestyle modifications (LSM) in Iraqi immigrants to Sweden at risk for T2D. Design A qualitative thematic analysis was conducted on data coll
Non-western immigrants have a higher prevalence of type 2 diabetes and earlier onset than non-immigrant Swedes. In this 10-year follow-up including all people in Sweden diagnosed with type 2 diabetes from 2006 onwards (i.e. prescribed glucose lowering medication for type 2 diabetes), the total and cause-specific mortality of first-generation immigrants with type 2 diabetes is lower than in non-imm
Autoantigen discovery is a critical challenge for the understanding and diagnosis of autoimmune diseases. While autoantibody markers in current clinical use have been identified through studies focused on individual disorders, we postulated that a reverse approach starting with a putative autoantigen to explore multiple disorders might hold promise. We here targeted the epidermal protein transglut
cBN-based materials are well known for their high chemical inertness and high performance. The variation of binder phase type and amount enable improvement of performance even more. Comprehensive investigation of the influence of type of niobium compound (NbC and NbN) as a binder phase for cBN-based materials were done. Samples were prepared by high pressure high temperature (HPHT) sintering under
This study aims to evaluate the accuracy of location (x, y and z) using a Magellan GPS NAV 1000 receiver. The position of a known reference point was compared with 50 fix points measured in two-dimensional (2D) mode (x, y) and with 50 fix points measured in three-dimensional (3D) mode (x, y and z). The mean errors and the root mean square errors (RMSE) in the Euclidian distances between the refere
Objectives: To investigate the interaction effect of sex and early vs. late onset of Alzheimer’s disease (AD) on long-term cognitive and functional outcomes and survival. Methods: The Swedish Alzheimer Treatment Study (SATS) is a prospective, observational, multicentre study of clinical practice involving 1,017 participants diagnosed with mild-to-moderate AD at the start of cholinesterase inhibito
The role of patient participation in forensic psychiatric care is unclear, but has been emphasised as important in recent research. This study aims to describe patients’ lived experiences of participation in high-security, forensic psychiatric settings. Sixteen patient interviews were performed in this phenomenological study and analysed with a Reflective Lifeworld Research approach (RLR). Results
Vertically aligned metal halide perovskite (MHP) nanowires are promising for various optoelectronic applications, which can be further enhanced by heterostructures. However, present methods to obtain free-standing vertically aligned MHP nanowire arrays and heterostructures lack the scalability needed for applications. We use a low-temperature solution process to prepare free-standing vertically al

BACKGROUND: Prospective and detailed investigations of smoking and prostate cancer (PCa) risk and death are lacking.OBJECTIVE: To investigate prediagnosis smoking habit (status, intensity, duration, and cessation) as a risk factor, on its own and combined with body mass index (BMI), for PCa incidence and death.DESIGN, SETTING, AND PARTICIPANTS: We included 351448 men with smoking information from
Lead has traditionally been added to brass alloys to achieve high machinability, but the exact mechanisms at work are still debated. Lead-free brass alternatives could be developed if these mechanisms were better understood. Accordingly, machinability characteristics were investigated for two brass alloys with similar mechanical properties and phase composition, but with very different machining c
BACKGROUND: Cardiac rehabilitation is central in reducing mortality and morbidity after myocardial infarction. However, the fulfillment of guideline-recommended cardiac rehabilitation targets is unsatisfactory. eHealth offers new possibilities to improve clinical care.OBJECTIVE: This study aims to assess the effect of a web-based application designed to support adherence to lifestyle advice and se
