Objective: Primary hyperparathyroidism (PHPT) is associated with cardiovascular morbidity and premature death but the underlying mechanisms are incompletely understood. The aim of this study was to investigate if adrenergic dysfunction may be a contributing factor. Patients and methods: Forty-nine patients with mild PHPT (serum calcium 2.7 ± 0.1 mmol/L) and 48 control subjects, matched for age an
We report on a forward RNAi screen in primary human hematopoietic stem and progenitor cells, using pooled lentiviral shRNA libraries deconvoluted by next generation sequencing. We identify MAPK14/p38α as a modulator of ex vivo stem cell proliferation and show that pharmacological inhibition of p38 dramatically enhances the stem cell activity of cultured umbilical cord blood derived hematopoietic c
More knowledge concerning the association between physical activity and objectively measured attributes of the built environment is needed. Previous studies on the association between objectively measured neighborhood walkability, physical activity, and walking have been conducted in the U.S. or Australia and research findings are available from only one country in Europe - Belgium. The first aim
Absorption (mu (a)) and reduced scattering (mu (s)') spectra of turbid media were quanti fied with a noncontact imaging approach based on a Fourier-transform interferometric imaging system (FTIIS). The FTIIS was used to collect hyperspectral images of the steady-state diffuse reflectance from turbid media. Spatially resolved reflectance data from Monte Carlo simulations were fitted to the recorded
This paper presents a systematic approach to robust preconditioning for gradient-based nonlinear inverse scattering algorithms. In particular, one- and two-dimensional inverse problems are considered where the permittivity and conductivity profiles are unknown and the input data consist of the scattered field over a certain bandwidth. A time-domain least-squares formulation is employed and the inv
Objectives: The aim of the study was to further psychometrically evaluate the instrument "Pain Impact Inventory" (PII) in various subgroups. Methods: The sample comprised 384 persons (aged between 18 and 102 years) who reported chronic pain. The instrument PII was evaluated in terms of construct validity as well as reliability. The instrument's validity was investigated through corrected item-tota
Lack of or dysfunction in osteoclasts result in osteopetrosis, a group of rare but often severe, genetic disorders affecting skeletal tissue. Increase in bone mass results in skeletal malformation and bone marrow failure that may be fatal. Many of the underlying defects have lately been characterized in humans and in animal models of the disease. In humans, these defects often involve mutations in
Mitochondrial metabolism controls insulin secretion from the pancreatic beta-cell. Type 2 Diabetes evolves when the beta-cells fail to release appropriate amounts of insulin, causing metabolic dysregulation and hyperglycemia. It is attractive to assume that mitochondrial dysfunction plays a decisive role in these processes. Indeed, while being a rare condition, genetically determined dysfunction o
BACKGROUND: High doses of aspirin counteract the beneficial effects of angiotensin-converting enzyme (ACE) inhibitors. It is not known how low-dose aspirin, with concomitant ACE-inhibitor treatment, affects renal function. AIM: To study renal effects of different doses of aspirin in elderly healthy volunteers who had an activated renin-angiotensin system. METHODS: Sixteen subjects each received tw
Purpose: In order to evaluate long-term effects on neurodevelopment in children born to women with epilepsy during pregnancy we studied the children's school grades at age 16. Methods: We used the Patient Register, the Medical Birth Register, and a local study at South Hospital, Stockholm, to identify women with epilepsy in Sweden who had given birth between 1973 and 1986. The Swedish School Mark
We know little about the health consequences of human exposure to microorganisms in the environment. This may largely be due to the lack of universally accepted, sensitive, reproducible, non-discriminatory, and health relevant methods for characterizing the exposure. In this review, some of the different mass spectrometry methods that have been developed for measuring endotoxin and peptidoglycan f
Previous studies have shown that QRS prolongation is a sign of depressed collateral flow and increased rate of myocardial cell death during coronary occlusion. The aims of this study were to evaluate ischemic QRS prolongation as a biomarker of severe ischemia by establishing the relationship between prolongation and collateral flow experimentally in a dog model, and test if the same pattern of isc
A deficient retinoic acid signaling has been suggested to be an important cause of the clinical inefficacy of all-trans retinoic acid (ATRA) therapy in non-promyelocytic (non-PML) forms of acute myeloid leukemia (AML). The general aim of the present work was to explore novel ways to take advantage of the anti-leukemic potential of ATRA, and, specifically, to search for a synergism between ATRA and
BRCA1 and BRCA2 screening in women at high-risk of breast cancer results in the identification of both unambiguously defined deleterious mutations and sequence variants of unknown clinical significance (VUS). We examined a population-based sample of young women with contralateral breast cancer (CBC, n=705) or unilateral breast cancer (UBC, n=1398). We identified 470 unique sequence variants, of wh
Breathlessness is a major cause of suffering and distress and little is known about the trajectory of breathlessness near death.
The third Human Variome Project (HVP) Meeting "Integration and Implementation" was held under UNESCO Patronage in Paris, France, at the UNESCO Headquarters May 10-14, 2010. The major aims of the HVP are the collection, curation, and distribution of all human genetic variation affecting health. The HVP has drawn together disparate groups, by country, gene of interest, and expertise, who are working
