Shadowing from vehicles can significantly degrade the performance of vehicle-to-vehicle (V2V) communication in multilink systems, e.g., vehicular ad-hoc networks (VANETs). It is thus important to characterize and model the influence of common shadowing objects like cars properly when designing these VANETs. Despite the fact that for multilink systems it is essential to model the joint effects on t

Background and Purpose: Stroke is one of the dominant causes of death and adult disability in the world. There is a need for novel therapeutic approaches to improve functional recovery and outcome after stroke, and experimental studies have shown that stem cell-based therapies (SCT) hold much potential in this regard. This thesis, comprising 5 papers, aims to explore and describe clinical symptoms

PURPOSE: To develop and assess a technique for self-gated fetal cardiac cine magnetic resonance imaging (MRI) using tiny golden angle radial sampling combined with iGRASP (iterative Golden-angle RAdial Sparse Parallel) for accelerated acquisition based on parallel imaging and compressed sensing.MATERIALS AND METHODS: Fetal cardiac data were acquired from five volunteers in gestational week 29-37 a

Background: Variation in the 10 toll-like receptor (TLR) genes has been significantly associated with allergic rhinitis (AR) in several candidate gene studies and three large genome-wide association studies. These have all investigated common variants, but no investigations for rare variants (MAF≤1%) have been made in AR. The present study aims to describe the genetic variation of the promoter and

La2MgNi9-related alloys are superior metal hydride battery anodes as compared to the commercial AB5 alloys. Nd-substituted La2-yNdyMgNi9 intermetallics are of particular interest because of increased diffusion rate of hydrogen and thus improved performance at high discharge currents. The present work presents in operando characterization of the LaNdMgNi9 intermetallic as anode for the nickel metal

Abstract: Bladder cancer is a heterogenous disease, ranging from minimally invasive, low-grade tumours with lowrecurrence rates and mortality on one end of the spectrum, and muscle invasive, high-grade disease prone torecurrence, progression and death at the other end.The aim of this thesis was to investigate the expression, clinicopathological correlates and prognostic significanceof the candidat

We show that for several pattern graphs on four vertices (e.g., C4), their induced copies in host graphs with n vertices and no clique on k + 1 vertices can be deterministically detected in time Õ (nωkμ + n2k2), where Õ (f) stands for O(f(log f)c) for some constant c, and μ ≈ 0. 46530. The aforementioned pattern graphs have a pair of non-adjacent vertices whose neighborhoods are equal. By consider

The objective of this study was to develop, test and evaluate a specifically defined interdisciplinary approach—the human-centred approach—as applied to a case study, Iron Age Öland. Four themes were selected to highlight different aspects of particular interest in Öland: taphonomy, diet, migration, and social organization. The uncremated human skeletal remains from Öland are the basis for this st

Aim: The aim of this study was to evaluate the effectiveness of non-surgical periodontal treatment (NSPT) and its influential factors in a large Chinese population with chronic periodontitis. Methods: Periodontal examination data of 10,789 patients with at least one periodontal re-evaluation record were extracted from a hospital-based electronic periodontal charting record system. Probing depth (P

Identifying the molecular basis of environmentally induced phenotypic variation presents exciting opportunities for furthering our understanding of how ecological processes and the environment can shape the phenotype. Urban and rural environments present free-living organisms with different challenges and opportunities, which have marked consequences for the phenotype, yet little is known about re

Air pollution has been suggested to affect fetal growth, but more data is needed to assess the timing of exposure effects by using ultrasound measures. It is also important to study effects in low exposure areas to assess eventual thresholds of effects. The MAPSS (Maternal Air Pollution in Southern Sweden) cohort consists of linked registry data for around 48,000 pregnancies from an ultrasound dat

Introduction: There is an ever reoccurring question in medical practice: Does the positive attitude and communication of the medical staff make any diff erence Aim: Our aim is to present a comprehensive overview of the medically relevant eff ects of positive suggestions by reviewing the recent literature. Methods: We will review the studies measuring the eff ects of suggestive communication of the

All major amputations of the lower limb due to occlusive arterial disease were studied prospectively and consecutively during one year in the 5 hospitals in Malmöhus county, Sweden. The patients were followed for 6 months after the primary amputation of which 136 were through the tibia, 6 through the knee and 35 through the femur. One hundred and seventy-seven patients (92 men and 85 women) were i

Adult hippocampal neurogenesis is strongly impaired in Alzheimer's disease (AD). In several mouse models of AD, it was shown that adult-born neurons exhibit reduced survival and altered synaptic integration due to a severe lack of dendritic spines. In the present work, using the APPxPS1 mouse model of AD, we reveal that this reduced number of spines is concomitant of a marked deficit in their neur
