The Northern high latitudes are warming twice as fast as the global average, and permafrost has become vulnerable to thaw. Changes to the environment during thaw leads to shifts in microbial communities and their associated functions, such as greenhouse gas emissions. Understanding the ecological processes that structure the identity and abundance (i.e., assembly) of pre- and post-thaw communities

Experimental observation of 34Si as a proton bubble nuclei has heated up the interest in the study of exotic bubble shaped nuclei. In this work, some of the potential doubly bubble-like (for proton as well as neutron both simultaneously) cases have been explored using relativistic Hartree-Bogoliubov (RHB) in light mass region, specially around N or Z = 14. Further, the role of pairing and the evol

Some people react to smells or chemicals at levels far below toxicological thresholds with nonspecific symptoms, fear and social isolation. They may be diagnosed with multiple chemical sensitivity. There is no empirical evidence indicating that this condition is explained by toxicological mechanisms, even though a number of theories have been proposed. The authors of this review conclude that this

OBJECTIVE: To determine if putrescine and the higher polyamines spermidine and spermine are released from cultured vascular smooth muscle cells.MATERIAL: Vascular smooth muscle cell line A7r5.TREATMENT: Cells were treated with aminoguanidine (10 or 100 microM) for 1 to 24 h with or without fetal calf serum (10%) present in the culture medium.METHODS: Cellular and medium concentrations of polyamine

Surface emissions of CO2 from fossil fuel combustion (ΦFFCO2) are estimated for the Netherlands for the period of May 2006-June 2009 using ambient atmospheric observations taken at station Lutjewad in the Netherlands (6°21'E, 53°24'N, 1 m. a.s.l.). Measurements of Δ14C on 2-weekly integrations of CO2 and CO mixing ratios are combined to construct a quasi-continuous proxy record (FFCO2*) from which

A novel rapid acquisition algorithm, called sequential block search, is proposed for impulse radio systems, which can reduce the mean acquisition time considerably. The algorithm is compared to the conventional serial search algorithm and output statistics for both algorithms are derived for a binary phase-shift keyed random time hopping impulse radio system. The mean acquisition time formulas are

The use of mammalian target of rapamycin (mTOR) inhibitors have been limited by adverse events (AE), including delayed wound healing. We retrospectively reviewed all AE and serious AE (SAE) in The Scandinavian heart transplant (HTx) everolimus (EVE) de novo trial with early calcineurin (CNI) avoidance (SCHEDULE). The aim of the study was to compare wound complications between EVE and CNI based reg

This study sought to assess the safety and efficacy of transcatheter valve annuloplasty in patients with mitral regurgitation (MR).

Deterministic lateral displacement (DLD) devices separate micrometer-scale particles in solution based on their size using a laminar microfluidic flow in an array of obstacles. We investigate array geometries with rational row-shift fractions in DLD devices by use of a simple model including both advection and diffusion. Our model predicts multidirectional sorting modes that could be experimentall

BACKGROUND: There is mounting evidence that children born after in vitro fertilization (IVF) run an increased risk of neurological complications and notably cerebral palsy. Whether developmental disturbances occur more often than expected is debated. AIM: To investigate the risk for ADHD in children conceived after IVF. METHODS: Children conceived after IVF and born between 1982 and 2005 were iden

AIM: To survey the histopathological abnormalities in breasts of women who have undergone risk reducing mastectomy and to evaluate the effect of this measure on future breast cancer development. PATIENTS/METHODS: Between August 1995 and October 2006 100 consecutive women with a hereditary increased risk of breast cancer underwent prophylactic mastectomy (PM) at Malmö University Hospital. Fifty of

Background:Familial nervous system cancers are rare and limited data on familial aspects are available particularly on site-specific tumours.Methods:Data from five Nordic countries were used to analyse familial risks of nervous system tumours. Standardised incidence ratios (SIRs) were calculated for offspring of affected relatives compared with offspring of non-affected relatives.Results:The total

OBJECTIVES: This study examined which individual and national factors affect condom use among adolescents. STUDY DESIGN: Multilevel analysis. METHODS: This study reviewed the data on bullying, alcohol use and condom use provided by 18 European countries and subnational entities in the Health Behaviour in School-Aged Children survey. Another eight contextual variables were also analysed. Three mult

To investigate the association between knee pain and signs of inflammation in the infrapatellar fat pad (IPFP) in obese patients with knee osteoarthritis (KOA).
