Argonaute2 Mediates Compensatory Expansion of the Pancreatic β Cell.

Pancreatic β cells adapt to compensate for increased metabolic demand during insulin resistance. Although the microRNA pathway has an essential role in β cell proliferation, the extent of its contribution is unclear. Here, we report that miR-184 is silenced in the pancreatic islets of insulin-resistant mouse models and type 2 diabetic human subjects. Reduction of miR-184 promotes the expression of

Genetics of diabetes complications.

Chronic hyperglycemia and duration of diabetes are the major risk factors associated with development of micro- and macrovascular complications of diabetes. Although it is believed that hyperglycemia induces damage to the particular cell subtypes, e.g., mesangial cells in the renal glomerulus, capillary endothelial cells in the retina, and neurons and Schwann cells in peripheral nerves, the exact

Changing From Conventional to Eversion Endarterectomy in Carotid Artery Disease-A Safe Transition Process in the Short and Long Term

Objectives: To evaluate the transition process from conventional carotid endarterectomy (cCEA) to eversion carotid endarterectomy (eCEA). Methods: Patients operated with carotid endarterectomy (CEA; 164 patients, 171 CEA) in 2002-2003 were retrospectively included. Results: In 2002, cCEA was applied in 64 (80%) and eCEA in 16 (20%) patients. There was an inversion on the preponderant surgical tech

The genetics of diabetic complications.

The rising global prevalence of diabetes mellitus is accompanied by an increasing burden of morbidity and mortality that is attributable to the complications of chronic hyperglycaemia. These complications include blindness, renal failure and cardiovascular disease. Current therapeutic options for chronic hyperglycaemia reduce, but do not eradicate, the risk of these complications. Success in defin

Structural and functional differences between L-type calcium channels: crucial issues for future selective targeting

Within the family of voltage-gated calcium channels (VGCCs), L-type channels (L-VGCCs) represent a well-established therapeutic target for calcium channel blockers, which are widely used to treat hypertension and myocardial ischemia. L-VGCCs outside the cardiovascular system also control key physiological processes such as neuronal plasticity, sensory cell function (e.g. in the inner ear and retin

Physical exercise and internet-based cognitive behavioural therapy in the treatment of depression: randomised controlled trial.

BackgroundDepression is common and tends to be recurrent. Alternative treatments are needed that are non-stigmatising, accessible and can be prescribed by general medical practitioners.AimsTo compare the effectiveness of three interventions for depression: physical exercise, internet-based cognitive-behavioural therapy (ICBT) and treatment as usual (TAU). A secondary aim was to assess changes in s

RNA sequencing: current and prospective uses in metabolic research.

Previous global RNA analysis was restricted to known transcripts in species with a defined transcriptome. Next generation sequencing has transformed transcriptomics by making it possible to analyse expressed genes with an exon level resolution from any tissue in any species without any a priori knowledge of which genes that are being expressed, splice patterns or their nucleotide sequence. In addi

The diabetes susceptibility gene clec16a regulates mitophagy.

Clec16a has been identified as a disease susceptibility gene for type 1 diabetes, multiple sclerosis, and adrenal dysfunction, but its function is unknown. Here we report that Clec16a is a membrane-associated endosomal protein that interacts with E3 ubiquitin ligase Nrdp1. Loss of Clec16a leads to an increase in the Nrdp1 target Parkin, a master regulator of mitophagy. Islets from mice with pancre

Meta-analysis of gene-level tests for rare variant association.

The majority of reported complex disease associations for common genetic variants have been identified through meta-analysis, a powerful approach that enables the use of large sample sizes while protecting against common artifacts due to population structure and repeated small-sample analyses sharing individual-level data. As the focus of genetic association studies shifts to rare variants, genes

Kingnites diamondi gen. et sp nov., an exceptionally large Silurian paulinitid (Annelida; Polychaeta) from shallow marine settings of Baltoscandia

The polychaete annelid Kingnites diamondi, a new paulinitid genus and species, is described from the Silurian of Baltoscandia. Its large maxillae differ morphologically from those of all other known paulinitids, particularly in being very elongate and having conspicuous myocoele openings and posterior portions of the first maxillae (MI). Albeit rare, this polychaete taxon is highly characteristic

Träning och tävling online: Raidkultur i World of Warcraft

Competitive gaming, or the growing sport like scene around computer games, has not been studied much in the academic field of Games Studies. Drawing on ethnographic and interview work both inside and outside the game this thesis examines player-produced culture around raids in the Massive Multiplayer Online Game World of Warcraft. Competitive elements in WoW, such as races to be the “World First”

Energieffektivisering vid snötillverkning

Idre Fjälls snow production has been analyzed in cooperation with Snowtech AB. A survey of the energy use and how to decrease the energy use was carried out. The first part is about snow and snowmaking. Natural snow consists of water molecules that form a hexagonal pattern in solid state. The reason to the hexagonal pattern is due to dendritic growth during the snow crystals journey through the cl
