Are Stem Cell-Based Therapies for Parkinson's Disease Ready for the Clinic in 2016?

Recent news of an impending clinical cell transplantation trial in Parkinson's disease using parthenogenetic stem cells as a source of donor tissue have raised hopes in the patient community and sparked discussion in the research community. Based on discussions held by a global collaborative initiative on translation of stem cell therapy in Parkinson's disease, we have identified a set of key ques

Robot-Assisted laparoscopy for genital organ prolapse

Support of the anterior and posterior vaginal wall is related to the support and position of the vaginal apex. Therefore, support of the vaginal apex, with or without a concomitant procedure to prevent the formation of an enterocele, is the base for prolapse surgery. A number of surgical approaches, vaginal, open or laparoscopic have been described with or without preservation of the uterus. The u

Different modelling approaches to coupling wall and floor panels within a dynamic finite element model of a lightweight building

This paper presents an investigation of a skeleton based coupling technique used for the assembly of different modules, i.e. walls and floors, in a modular finite element model. For simplicity the skeleton is introduced in the intersections of the panels. In this way all panels can be constrained to the global skeleton, leading to a removal of the constrained degrees of freedom (DOFs) in the indiv

The prevalence and predictive value of the SLC30A8 R325W polymorphism and zinc transporter 8 autoantibodies in the development of GDM and postpartum type 1 diabetes

The objectives were to evaluate possible associations between the SLC30A8 R325W polymorphism and gestational diabetes mellitus (GDM) as well as postpartum development of type 2 diabetes. Furthermore, we wanted to confirm the prevalence of zinc transporter 8 autoantibodies (ZnT8A), as previously reported, in a larger population and study its predictive value in relation to other β cell specific aut

Epigenetic and Transcriptional Alterations in Human Adipose Tissue of Polycystic Ovary Syndrome

Genetic and epigenetic factors may predispose women to polycystic ovary syndrome (PCOS), a common heritable disorder of unclear etiology. Here we investigated differences in genome-wide gene expression and DNA methylation in adipose tissue from 64 women with PCOS and 30 controls. In total, 1720 unique genes were differentially expressed (Q < 0.05). Six out of twenty selected genes with largest exp

Gender-related differences in urothelial carcinoma of the bladder : a population-based study from the Swedish National Registry of Urinary Bladder Cancer

OBJECTIVE: The aim of this investigation was to describe tumour characteristics, treatments and survival in patients with urinary bladder cancer (UBC) in a national population-based cohort, with special reference to gender-related differences.MATERIAL AND METHODS: All primary UBC patients with urothelial pathology reported to the Swedish National Registry of Urinary Bladder Cancer (SNRUBC) from 19

Multi-vendor, multicentre comparison of contrast-enhanced SSFP and T2-STIR CMR for determining myocardium at risk in ST-elevation myocardial infarction

AIMS: Myocardial salvage, determined by cardiac magnetic resonance imaging (CMR), is used as end point in cardioprotection trials. To calculate myocardial salvage, infarct size is related to myocardium at risk (MaR), which can be assessed by T2-short tau inversion recovery (T2-STIR) and contrast-enhanced steady-state free precession magnetic resonance imaging (CE-SSFP). We aimed to determine how T

A novel strategy to protect against influenza-induced pneumococcal disease without interfering with commensal colonization

Streptococcus pneumoniae commonly inhabits the nasopharynx as a member of the commensal biofilm. Infection with respiratory viruses, such as influenza A virus, induces commensal S. pneumoniae to disseminate beyond the nasopharynx and to elicit severe infections of the middle ears, lungs, and blood that are associated with high rates of morbidity and mortality. Current preventive strategies, includ

Modification of a traditional breakfast leads to increased satiety along with attenuated plasma increments of glucose, C-peptide, insulin, and glucose-dependent insulinotropic polypeptide in humans

Our hypothesis was that carbohydrate, fat, and protein contents of meals affect satiety, glucose homeostasis, and hormone secretion. The objectives of this crossover trial were to examine satiety, glycemic-insulinemic response, and plasma peptide levels in response to 2 different recommended diabetes diets with equivalent energy content. One traditional reference breakfast and one test breakfast,

Neuroblastoma patient-derived orthotopic xenografts reflect the microenvironmental hallmarks of aggressive patient tumours

Treatment of high-risk childhood neuroblastoma is a clinical challenge hampered by a lack of reliable neuroblastoma mouse models for preclinical drug testing. We have previously established invasive and metastasising patient-derived orthotopic xenografts (PDXs) from high-risk neuroblastomas that retained the genotypes and phenotypes of patient tumours. Given the important role of the tumour microe

From Extensive to Involutionary Growth: A Dialectic Interpretation of the Boom and Busts of Cocoa Production in the Gold Coast

African economic history has undergone impressive revitalization in the past decade. Much of the recent work is, quite naturally, inspired by developments in economic history at large, and increasingly – indirectly or directly – using markets as the organizing principle in understanding how economies evolve over time. More specifically, recent work assumes that markets create the possibility to us

Design Automation for IEEE P1687

The IEEE P1687 (IJTAG) standard proposal aimsat standardizing the access to embedded test and debug logic(instruments) via the JTAG TAP. P1687 specifies a componentcalled Segment Insertion Bit (SIB) which makes it possible toconstruct a multitude of alternative P1687 instrument accessnetworks for a given set of instruments. Finding the best accessnetwork with respect to instrument access time and

Measurement Point Selection for In-Operation Wear-Out Monitoring

In recent IC designs, the risk of early failure due to electromigration wear-out has increased due to reduced feature dimensions. To give a warning of impending failure, wearout monitoring approaches have included delay measurement circuitry on-chip. Due to the high cost of delay measurement circuitry this paper presents a method to reduce the number of necessary measurement points. The proposed m

Efficient Embedding of Deterministic Test Data

Systems with many integrated circuits (ICs), often of the same type, are increasingly common to meet the constant performance demand. However, systems in recent semiconductor technologies require not only manufacturing test, but also in-field test. Preferably, the same test set is utilized both at manufacturing test and in-field test. While deterministic test patterns provide high fault coverage,

Energy-Efficient Fault Tolerance in Chip Multiprocessors Using Critical Value Forwarding

Relentless CMOS scaling coupled with lower design tolerances is making ICs increasingly susceptible to wear-out related permanent faults and transient faults, necessitating on-chip fault tolerance in future chip microprocessors (CMPs). In this paper we introduce a new energy-efficient fault-tolerant CMP architecture known as Redundant Execution using Critical Value Forwarding (RECVF). RECVF is bas

Multiplexed redundant execution: A technique for efficient fault tolerance in chip multiprocessors

Continued CMOS scaling is expected to make future micro-processors susceptible to transient faults, hard faults, manufacturing defects and process variations causing fault tolerance to become important even for general purpose processors targeted at the commodity market. Tomitigate the effect of decreased reliability, a number of fault-tolerant architectures have been proposed that exploit the nat

On Minimization of Peak Power for Scan Circuit during Test

Scan circuit generally causes excessive switching activity compared to normal circuit operation. The higher switching activity in turn causes higher peak power supply current which results into supply voltage droop and eventually yield loss. This paper proposes an efficient methodology for test vector re-ordering to achieve minimum peak power supported by the given test vector set. The proposed me

Fault-tolerant average execution time optimization for general-purpose multi-processor system-on-chips

Fault-tolerance is due to the semiconductor technology development important, not only for safety-critical systems but also for general-purpose (non-safety critical) systems. However, instead of guaranteeing that deadlines always are met, it is for general-purpose systems important to minimize the average execution time (AET) while ensuring fault-tolerance. For a given job and a soft (transient) e
