Inhibition of polyamine uptake potentiates the anti-proliferative effect of polyamine synthesis inhibition and preserves the contractile phenotype of vascular smooth muscle cells.

Increased vascular smooth muscle cell (VSMC) proliferation is a factor in atherosclerosis and injury-induced arterial (re)stenosis. Inhibition of polyamine synthesis by α-difluoro-methylornithine (DFMO), an irreversible inhibitor of ornithine decarboxylase, attenuates VSMC proliferation with high sensitivity and specificity. However, cells can escape polyamine synthesis blockade by importing polya

7-T MR-from research to clinical applications?

Over 20?000 MR systems are currently installed worldwide and, although the majority operate at magnetic fields of 1.5?T and below (i.e. about 70%), experience with 3-T (in high-field clinical diagnostic imaging and research) and 7-T (research only) human MR scanners points to a future in functional and metabolic MR diagnostics. Complementary to previous studies, this review attempts to provide an

The eco-evolutionary consequences of interspecific phenological asynchrony - a theoretical perspective

The timing of biological events (phenology) is an important aspect of both a species' life cycle and how it interacts with other species and its environment. Patterns of phenological change have been given much scientific attention, particularly recently in relation to climate change. For pairs of interacting species, if their rates of phenological change differ, then this may lead to asynchrony b

A Pediatric Bone Mass Scan Has Poor Ability to Predict Adult Bone Mass: A 28-Year Prospective Study in 214 Children.

As the correlation of bone mass from childhood to adulthood is unclear, we conducted a long-term prospective observational study to determine if a pediatric bone mass scan could predict adult bone mass. We measured cortical bone mineral content (BMC [g]), bone mineral density (BMD [g/cm(2)]), and bone width (cm) in the distal forearm by single photon absorptiometry in 120 boys and 94 girls with a

Experiences of providing prosthetic and orthotic services in Sierra Leone - the local staff's perspective

In Sierra Leone, West Africa, there are many people with disabilities in need of rehabilitation services after a long civil war. Purpose: The aim of this qualitative study was to explore the experiences of prosthetic and orthotic service delivery in Sierra Leone from the local staff's perspective. Method: Fifteen prosthetic and orthotic technicians working at all the rehabilitation centres providi

The environmental context of a prehistoric rock carving on the Bjare Peninsula, Scania, southern Sweden

Palaeoecological analysis of peat deposits from a small bog at Lingarden, southern Sweden, have been used to examine the nature and timing of vegetation changes and anthropogenic activity associated with a nearby rock carving located close to the edge of the wetland. This study is the first of its type to investigate the environmental context of rock carvings in southern Sweden. Debate has tended

Follow-up duration influences the relative importance of OGTT and optimal timing of glucose measurements for predicting future type 2 diabetes.

OBJECTIVE: To examine the impact of follow-up duration on the incremental prognostic yield of a baseline oral glucose tolerance test (OGTT) for predicting type 2 diabetes and to assess the discrimination ability of blood glucose (BG) obtained at different time points during OGTT. DESIGN: Prospective, population-based cohort study (Malmö Preventive Project) with subject inclusion 1974-1992. METHO

Paediatric ECMO at low-volume paediatric cardiac centres in the Nordic countries

BackgroundExtracorporeal membrane oxygenation (ECMO) is a life-saving resource-intensive technology for patients with respiratory and/or circulatory failure. We aimed to evaluate outcome data from three Nordic paediatric centres comparing with data from the International Registry of the Extracorporeal Life Support Organization (ELSO) and selected high-volume single-centre studies. MethodsOne-hundr

Neighborhood Walkability, Income, and Hour-by-Hour Physical Activity Patterns.

PURPOSE: To investigate both the mean daily physical activity and the hour by hour physical activity pattern across the day using accelerometry, and how they are associated with neighborhood walkability and individual income. METHODS: Moderate physical activity (MPA) was assessed by accelerometry in 2,252 adults in the City of Stockholm, Sweden. Neighborhood walkability (residential density, stree

ATLAS measurements of the properties of jets for boosted particle searches

Measurements are presented of the properties of high transverse momentum jets, produced in proton-proton collisions at a center-of-mass energy of root s = 7 TeV. The data correspond to an integrated luminosity of 35 pb(-1) and were collected with the ATLAS detector in 2010. Jet mass, width, eccentricity, planar flow and angularity are measured for jets reconstructed using the anti-k(t) algorithm w

Assessing Recovery from the 2004 Indian Ocean Tsunami: An Application of Night-time Light Data and Vegetation Index

It has been 10 years since the Indian Ocean Tsunami caused serious damage to the coastal areas in South and Southeast Asia. The effects on vegetation and human settlements in the affected areas were enormous. This study presents the results of an analysis estimating the long-term recovery using two longitudinal remotely sensed dataset: 1. Moderate Resolution Imaging Spectroradiometer enhanced vege

A hyperelastic fibre-reinforced continuum model of healing tendons with distributed collagen fibre orientations.

The healing process of ruptured tendons is problematic due to scar tissue formation and deteriorated material properties, and in some cases, it may take nearly a year to complete. Mechanical loading has been shown to positively influence tendon healing; however, the mechanisms remain unclear. Computational mechanobiology methods employed extensively to model bone healing have achieved high fidelit

Usage of Finance Information Systems in Developing Countries: Identifying Factors During Implementation that Impact Use

An explorative study of factors affecting implementation and use of finance information systems (FISs) in developing countries is presented. The result is based on a field study investigating implementation of a finance information system at Makerere University, Uganda. Current literature suggests that how to implement information Systems (ISs) successfully is challenging, especially in developing

Invasive disease caused by Haemophilus influenzae in Sweden 1997-2009; evidence of increasing incidence and clinical burden of non-type b strains

Introduction of a conjugated vaccine against encapsulated Haemophilus influenzae type b (Hib) has led to a dramatic reduction of invasive Hib disease. However, an increasing incidence of invasive disease by H. influenzae non-type b has recently been reported. Non-type b strains have been suggested to be opportunists in an invasive context, but information on clinical consequences and related medic

The revised Lund-Malmo GFR estimating equation outperforms MDRD and CKD-EPI across GFR, age and BMI intervals in a large Swedish population

Background: The performance of creatinine-based glomerular filtration rate (GFR) estimating equations may vary in subgroups defined by GFR, age and body mass index (BMI). This study compares the performance of the Modification of Diet in Renal Disease (MDRD) study and Chronic Kidney Disease Epidemiology Collaboration (CKD-EPI) equations with the revised Lund-Malmo equation (LM Revised), a new equa

Sex Differences in Patient-Reported Outcomes After Anterior Cruciate Ligament Reconstruction: Data From the Swedish Knee Ligament Register.

BACKGROUND: Female gender is a risk factor for sustaining anterior cruciate ligament (ACL) injury. However, little is known about possible sex differences in patients with ACL injury/reconstruction. PURPOSE: To study sex differences in patient-reported outcomes before and at 1 and 2 years after ACL reconstruction and to present reference values. STUDY DESIGN: Cohort study; Level of evidence, 2. ME

Multicarrier faster-than-Nyquist transceivers: hardware architecture and performance analysis

This paper evaluates the hardware aspects of multicarrier faster-than-Nyquist (FTN) signaling transceivers. The choice of time-frequency spacing of the symbols in an FTN system for improved bandwidth efficiency is targeted towards efficient hardware implementation. This work proposes a hardware architecture for the realization of iterative decoding of FTN multicarrier modulated signals. Compatibil
