The hypothalamus is the central regulator of energy homeostasis. Hypothalamic neuronal circuits are disrupted upon overfeeding, and play a role in the development of metabolic disorders. While mouse models have been extensively employed for understanding the mechanisms of hypothalamic dysfunction, functional magnetic resonance imaging (fMRI) on hypothalamic nuclei has been challenging. We implemen
INTRODUCTION: Information about the education, training and future employment prospects of Icelandic surgeons has not been available.MATERIALS AND METHODS: The study included all Icelandic surgeons, in all subspecialties, educated at the Faculty of Medicine at the University of Iceland. Information on specialty training, higher academic degrees and in which country these were obtained was collecte
Background: Identifying non-invasive and reliable blood-derived biomarkers for early detection of acute cellular rejection in heart transplant recipients is of great importance in clinical practice. MicroRNAs are small molecules found to be stable in serum and their expression patterns reflect both physiological and underlying pathological conditions in human. Methods: We compared a group of heart
Background We determined time frames for dilatation of anastomotic strictures (ASs) occurring during the first 2 years after esophageal atresia (EA) repair. Methods A retrospective study was conducted on children with EA (Gross type C) who underwent direct repair between January 2008 and March 2015 at a single tertiary center of pediatric surgery. Endoscopic signs of stricture were indications f
There have been increasing theoretical speculations and observational indications that certain globular clusters (GCs) could contain a sizeable population of stellar mass black holes (BHs). In this paper, we shortlist at least 29 Galactic GCs that could be hosting a subsystem of BHs (BHS). In a companion paper, we analysed results from a wide array of GC models (simulated with the MOCCA code for c
The aim of our study was to examine the pathophysiology of ST depression (STD) in leads V1-V3 in the setting of inferior ST elevation myocardial infarction (iSTEMI) through the perspective of cardiac magnetic resonance (CMR). Methods: Differences in myocardial area at risk (MaR), infarct size, ejection fraction and myocardial segment involvement by CMR were compared in MITOCARE trial patients with
BackgroundPower output and force development during exercise are thought to be important indices of performance in elite athletes. The aim of this preliminary study was to determine the forces applied at the footrest during ergometric kayaking in individual kayakers at different competitive levels.MethodsThree elite female kayakers participated voluntarily in the study. Oxygen consumption (VO2) an
Background: Atrial septal defect (ASD) is a congenital heart lesion that often remains undiagnosed until adulthood. The reasons for this may be multifactorial. It is, however, known that closure of a hemodynamically significant ASD improves exercise capacity. This study aimed to explore whether the aerobic capacity in late adolescence is associated with time to diagnosis and intervention in adult
The responses of 44 nociceptive neurones in the lumbar dorsal horn evoked by controlled mechanical stimulation of the skin, with or without conduction block in myelinated afferent fibres, were studied in the halothane-anaesthetized rat, in order to evaluate the effects of impulses in cutaneous nociceptive C fibres on dorsal horn neurones. Continuous non-noxious pinch of the skin evoked a short-lat
BACKGROUND: Enzalutamide is an oral androgen-receptor inhibitor that prolongs survival in men with metastatic castration-resistant prostate cancer in whom the disease has progressed after chemotherapy. New treatment options are needed for patients with metastatic prostate cancer who have not received chemotherapy, in whom the disease has progressed despite androgen-deprivation therapy.METHODS: In
In vitro digestion of marine oils has been reported to promote lipid oxidation, including the formation of reactive aldehydes (e.g., malondialdehyde (MDA) and 4-hydroxy-2-hexenal (HHE)). We aimed to investigate if human in vitro digestion of supplemental levels of oils from algae, cod liver, and krill, in addition to pure MDA and HHE, affect intestinal Caco-2 cell survival and oxidative stress. Ce
The present study highlights microbial assimilation of carbon (glucose) and nitrogen (NH3–N) from wastewater using heterotrophic bioconversion process. Experiments were conducted to study the role of heterotrophic microbes towards removal of carbon and nitrogen at varying initial concentrations of carbon (COD, 533 to 1600 mg/l) and nitrogen (NH3–N, 73 to 249 mg/l) keeping the initial biomass of mi
Introduction: Early assessment of hip fracture patients’ cognitive function is important for preventing pre- and postoperative complications. The aim of this study was twofold: (1) to assess prehospital cognitive function in hip fracture patients and establish whether cognitive status differs pre- and postoperatively between prehospital fast track care (PFTC) and the traditional emergency departme
Purpose: The purpose of this study was to evaluate whether an educational palliative care intervention improved the quality of life for next of kin to older persons in nursing homes. Methods: Altogether, 90 next of kin in the intervention group and 105 next of kin in the control group were included. Data were collected using the WHOQOL-BREF questionnaire, answered before and 3 months after the int
Peptides representing the C-terminal end of secretin were synthetized and their effects tested along with secretin on column-perifused isolated mouse pancreatic islets. Insulin release induced by 10 mmol/l D-glucose was potentiated by secretin tested in a concentration range of 0.01-10 μg/ml; the maximal effect was obtained with 1 μg/ml secretin. This effect was mimicked by 50-500 μg/ml NH2-Leu-Le
Blood mononuclear cells obtained from 17 newly diagnosed insulin-dependent diabetic (IDDM) patients treated with insulin for 5-7 days were assessed for the number of spontaneous and pokeweed mitogen (PWM)-stimulated immunoglobulin-secreting cells in a reverse haemolytic plaque assay. The spontaneous in vitro immunoglobulin secretion was evanescent and decreased in individual patients within 1-4 mo
A therapeutic removal of antibodies may be achieved by immunoadsorption (IA) or by plasma exchange (PE). The aim of this prospective randomised study was to compare the efficacy of these different techniques with regard to treatment of patients with rapidly progressive glomerulonephritis (RPG) having at least 50% crescents. Forty-four patients with a RPG were included for treatment either by IA or
Laser cooling is a well-established technique for the creation of ensembles of ultracold neutral atoms or positive ions. This ability has opened many exciting new research fields over the past 40 years. However, no negatively charged ions have been directly laser cooled because a cycling transition is very rare in atomic anions. Efforts of more than a decade currently have La- as the most promisin
