Owing to the prevalence of fractal patterns in natural scenery and their growing impact on cultures around the world, fractals constitute a common feature of our daily visual experiences, raising an important question: what responses do fractals induce in the observer? We monitored subjects’ EEG while they were viewing fractals with different fractal dimensions, and the results show that significa

As successful generation of insulin producing cells could be used for diabetes treatment, a concerted effort is being made to understand the molecular programs underlying islet beta cell formation and function. The closely related MafA and MafB transcription factors are both key mammalian beta cell regulators. MafA and MafB are co-expressed in insulin+ beta cells during embryogenesis, while in the

Cutaneous anesthesia (EMLA_cream) of the forearm results in rapid improvement of hand sensibility, and here we applied this concept in the lower extremity. This double-blind study with 40 volunteers randomized to cutaneous application of anesthetic cream to the lower leg showed a significant improvement 2 h after treatment in touch thresholds in the EMLA group as compared with the placebo group. I

The RWAAI (Repository and Workspace for Austroasiatic Intangible heritage) project aims at building a digital archive out of existing legacy data from the austroasiatic language family. One aspect of the project is the preservation of analogue legacy data. In this context, we have at our hands a large number of mostly-phonemic transcriptions of narrative monologues, often with accompanying sound r

ABSTRACT: The pathogenesis of systemic sclerosis (SSc) is characterized by autoimmunity, vasculopathy and fibrosis. IL-15 is a pleiotropic cytokine that has impact on immune, vascular and connective tissue cells. We therefore investigated IL-15 in the circulation of patients with early SSc and explored possible associations of serum IL-15 with vasculopathy and fibrosis. Serum levels of IL-15 were

The Wnt signaling pathway is frequently deranged in colorectal cancer and is a key target for future preventive and therapeutic approaches. Colorectal cancers associated with the hereditary nonpolyposis colorectal cancer (HNPCC) syndrome are characterized by wide-spread microsatellite instability, but show few gross genomic alterations. We characterized expression of the Wnt signaling pathway mark

Streptococcus pyogenes of the M1 serotype is frequently associated with severe streptococcal infections. M1 protein challenge can cause widespread microthrombosis, suggesting a role of platelets in streptococcal sepsis. Herein, we hypothesized that platelets may play a role in M1 protein-induced lung inflammation and injury. M1 protein was injected intravenously in C57Bl/6 mice. For platelet and n

Neural devices may play an important role in the diagnosis and therapy of several clinical conditions, such as stroke, trauma or neurodegenerative disorders, by facilitating motor and pain control. Such interfaces, chronically implanted in the CNS, need to be biocompatible and have the ability to stimulate and record nerve signals. However, neural devices of today are not fully optimized. Nanostru

Introduction: Testing for airway hyperresponsiveness with indirect stimuli as exercise or mannitol has been proposed to better reflect underlying airway inflammation, as compared with methacholine (MCh), believed to act directly on airway smooth muscle cells. Objective: To investigate whether different direct and indirect stimuli induces different patterns of obstruction, recorded as central and p

Health status and functional profile at admission of nursing home residents in Iceland over 11-year period. International Journal of Older People Nursing doi: 10.1111/j.1748-3743.2011.00287.x Background.  The knowledge over time of the health status and changes in care needs of newly admitted nursing home residents is limited. Objectives.  To investigate trends in residents' health status and func

Healthcare outcome is to achieve optimal health for each patient. It is a well-known phenomenon that patients suffer from care injuries. Operations managers have difficulties in seeing that the relationship between safety culture, values and attitudes affects the medical care to the detriment of the patient. The aim was to describe the views on patient safety by operations managers and the establi

The optimal extent of mesenteric resection in colon cancer surgery is not known. We have previously shown an increased mortality associated with wider mesenteric resection in right hemicolectomy. This study compares the short and long-term outcome in three variations of right hemicolectomy based on the position of the vascular ligature in the mesentery.

A total of 2090 patients with endometrial carcinoma were followed-up for at least five years. The treatment modalities, as well as the results of treatment, regarding 272 patients with disease relapse are presented. The results are not encouraging. We found no statistically significant difference regarding overall survival, when the patients were divided according to initial stage or ploidy status

The ongoing climate change affects biogeochemical cycling in terrestrial ecosystems, but the magnitude and direction of this impact is yet unclear. To shed further light on the climate change impact, we investigated alterations in the soil nitrogen (N) cycling in a Danish heathland after 5 years of exposure to three climate change factors, i.e. warming, elevated CO2 (eCO(2)) and summer drought, ap

Somatic stem cells are ultimately responsible for mediating appropriate organ homeostasis and have therefore been proposed to represent a cellular origin of the ageing process-a state often characterized by inappropriate homeostasis. Specifically, it has been suggested that ageing stem cells might succumb to replicative senescence by a mechanism involving the cyclin-dependent kinase inhibitor p16(
