High Myc pathway activity and low stage of neuronal differentiation associate with poor outcome in neuroblastoma.
The childhood cancer neuroblastoma arises in the developing sympathetic nervous system and is a genotypically and phenotypically heterogeneous disease. Prognostic markers of poor survival probability include amplification of the MYCN oncogene and an undifferentiated morphology. Whereas these features discriminate high- from low-risk patients with precision, identification of poor outcome low- and
Proghrelin peptides: Desacyl ghrelin is a powerful inhibitor of acylated ghrelin, likely to impair physiological effects of acyl ghrelin but not of obestatin A study of pancreatic polypeptide secretion from mouse islets.
BACKGROUND: Proghrelin, produced by the ghrelin (A-like) cells of the gastric mucosa, gives rise to cleavage products, including desacyl ghrelin, acyl ghrelin and obestatin. The products are thought to be secreted concomitantly. In an earlier study we found acyl ghrelin and obestatin, but not desacyl ghrelin, to suppress the release of hormones from isolated islets of mouse and rat pancreas. RESUL
The effect of memantine on sleep behaviour in dementia with Lewy bodies and Parkinson's disease dementia.
OBJECTIVE: Two common and characteristic sleep disturbances have been described in dementia with Lewy bodies (DLB) and Parkinson's disease dementia (PDD); excessive daytime sleepiness and REM sleep behaviour disorder (RBD). This study is an analysis of a secondary outcome measure of a larger study already reported, aimed to determine whether memantine has an effect on the sleep disturbances in DLB
Regulation of AMP-activated protein kinase by cAMP in adipocytes: Roles for phosphodiesterases, protein kinase B, protein kinase A, Epac and lipolysis.
AMP-activated protein kinase (AMPK) is an important regulator of cellular energy status. In adipocytes, stimuli that increase intracellular cyclic AMP (cAMP) have also been shown to increase the activity of AMPK. The precise molecular mechanisms responsible for cAMP-induced AMPK activation are not clear. Phosphodiesterase 3B (PDE3B) is a critical regulator of cAMP signaling in adipocytes. Here we
Costa Rica and Nicaragua before the International Court of Justice – Trying to work out the complicated relationship between law and the environment
Nicaragua and Costa Rica have twice turned to the International Court of Justice (ICJ) to resolve disputes related to environmental damage occurring in a transboundary context. In these two cases the Court has to consider at least two issues. The first issue concerns the territorial status of a disputed border area. The disagreement is triggered by natural variations of the San Juan River at the b
Indigenized Psychologies
The ongoing development of indigenized psychologies illustrates the conditions for the development and transfer of traditions of understanding between different social and cultural contexts. The indigenized psychologies are distinguished by being reactions to what is seen as modern mainstream Western (US) psychology, by being (more or less) anchored in the identified culture of its countries and b
Orthostatic Hypotension and Cardiac Changes After Long-Term Follow-Up.
Orthostatic hypotension (OH) increases the risk of incident cardiovascular disease (CVD) and all-cause mortality in population-based cohort studies. Whether OH is associated with development of cardiac anomalies has not been sufficiently explored.

Phagocytic properties in tumor astrocytes.
In glioblastoma multiforme (GBM), the pathophysiological events preceding and promoting an uncontrolled and remarkable growth is largely unknown. Studies on gliomas and macrophage expression have shown high levels of phagocytic cells, that is, microglial cells. It has also been demonstrated that human astrocytic cells and rat glioma cells are capable of phagocytosis. The purpose of this study was

Spatial variability and temporal trends in water-use efficiency of European forests
The increasing carbon dioxide (CO2) concentration in the atmosphere in combination with climatic changes throughout the lastcentury are likely to have had a profound effect on the physiology of trees: altering the carbon andwater fluxes passing throughthe stomatal pores. However, the magnitude and spatial patterns of such changes in natural forests remain highly uncertain.Here, stable carbon isoto
Belonging and Doing: Important Factors for Satisfaction with Sexual Relations as Perceived by People with Persistent Mental Illness.
BACKGROUND: It is increasingly acknowledged that satisfaction with sexual relations forms an important aspect of people's lives, but little is known of factors associated with this phenomenon among people with mental illness. AIM: This study aimed to investigate how demographic, social, clinical, and health-related factors were related to satisfaction with sexual relations. METHODS: Patients with
A non-functional retinoblastoma tumor suppressor (RB) pathway in premenopausal breast cancer is associated with resistance to tamoxifen.
The retinoblastoma tumor suppressor (RB) is important for retaining cell cycle control and loss of RB function is commonly observed in various malignancies. Experimental and animal studies have shown that RB knockdown in ER+ (estrogen receptor) cell lines and xenografts leads to resistance to tamoxifen, indicating that RB-inactivation could be linked to impaired response to specific cancer treatme
Is teriparatide or alendronate the best treatment for glucocorticoid-induced osteoporosis?
Social capital, political trust and experience of cannabis smoking: A population-based study in southern Sweden.
OBJECTIVE: To investigate whether political mistrust in the Riksdag (the national parliament in Sweden) is an independent characteristic of cannabis smokers, or whether it reflects low confidence in people in general, and therefore low social capital. METHOD: The 2004 public health survey in Skåne is a cross-sectional postal questionnaire study answered by 27,757 respondents aged 18-80 with a 59%
Multifocal electroretinography amplitudes increase after photocoagulation in areas with increased retinal thickness and hard exudates.
Abstract. Purpose: This study aimed to evaluate local response on multifocal electroretinography (mfERG) and to assess retinal thickness with optical coherence tomography (OCT) after focal laser treatment in areas with retinal oedema and exudates in patients with diabetic retinopathy. Methods: Twelve diabetes patients (aged 60 +/- 14 years, diabetes duration 16 +/- 8 years) treated with focal or g
A pilot study investigating lactic acid bacterial symbionts from the honeybee in inhibiting human chronic wound pathogens.
Treatment and management of chronic wounds is a large burden on the health sector and causes substantial suffering for the patients. We believe that 13 lactic acid bacteria (LAB) symbionts isolated from the honey crop of the honeybee are important players in the antimicrobial action of honey, by producing antimicrobial substances and can be used in combination with heather honey as an effective tr
Chronic iliac vein occlusion: midterm results of endovascular recanalization.
PURPOSE:To evaluate patency and clinical outcome in patients treated with endovascular recanalization and stent placement for chronic iliac vein occlusions. METHODS:During a 14-year period (1994-2008), 59 (38 women; median age 39 years) of 62 patients with chronic occlusion of the iliac vein segment in 66 limbs were successfully treated with endovascular recanalization and stent placement. A prosp
