Self-powered wireless carbohydrate/oxygen sensitive biodevice based on radio signal transmission.

Here for the first time, we detail self-contained (wireless and self-powered) biodevices with wireless signal transmission. Specifically, we demonstrate the operation of self-sustained carbohydrate and oxygen sensitive biodevices, consisting of a wireless electronic unit, radio transmitter and separate sensing bioelectrodes, supplied with electrical energy from a combined multi-enzyme fuel cell ge

Bacterial Outer Membrane Vesicles. Mediators of virulence and antibiotic resistance.

Popular Abstract in Swedish Luftvägsinfektioner som orsakas av bakterier och virus är en av de ledande orsakerna till sjukdom i världen. De kännetecknas av inflammation i svalg, hals, näsa, öron eller i lungorna. I näsa och hals finns en normalflora av bakterier som lever i samspel med sin värd och som normalt sett inte orsakar infektioner. Ibland kan dessa bakterier ändå orsaka sjukdom, som då imOuter membrane vesicles (OMV) have the size of nanoparticles and are released from the outer membrane of most Gram-negative bacteria. The OMV reflect the composition of the bacterial outer membrane, including lipids and virulence factors specific for the pathogen, and are involved in pathogenesis and bacterial survival. Moraxella catarrhalis and Haemophilus influenzae are Gram-negative bacterial s

Distinct evolution of TLR-mediated dendritic cell cytokine secretion in patients with limited and diffuse cutaneous systemic sclerosis

Background Systemic sclerosis (SSc) is an autoimmune disease and accumulating evidence suggests a role for Toll-like receptor (TLR)-mediated activation of dendritic cells (DCs). Objective To map TLR-mediated cytokine responses of DCs from patients with SSc. Methods 45 patients with SSc were included. Patients were stratified as having diffuse cutaneous SSc (dSSc) or limited cutaneous SSc (lSSc) ac

A long and winding road: Differentiating human embryonic stem cells into dopaminergic neurons

Popular Abstract in English Parkinson’s disease is the second common neurological disease whose major clinical symptom is progressive impairment in the ability to control the body movements. The symptoms are mainly caused by the gradual loss of dopamine producing neurons in a very specific part of the brain, termed substantia nigra. Although there exist some drug and surgical therapies, those mosParkinson’s disease is a progressive neurodegenerative disorder. Since the motor manifestations of the disease is associated with the loss of dopaminergic (DAergic) neurons in the substantia nigra pars compacta, cell replacement therapy is a promising approach for treatment. Although several different cell types have been used in clinical trials, with the recent findings of somatic cell nuclear tr

Predicting mortality of residents at admission to nursing home: A longitudinal cohort study

Background: An increasing numbers of deaths occur in nursing homes. Knowledge of the course of development over the years in death rates and predictors of mortality is important for officials responsible for organizing care to be able to ensure that staff is knowledgeable in the areas of care needed. The aim of this study was to investigate the time from residents' admission to Icelandic nursing h

Analysis of DFT-based channel estimators for OFDM

In this paper we analyze the performance of three low-complexity channel estimators, based on the discrete Fourier transform (DFT), for orthogonal frequency-division multiplexing (OFDM) systems. Estimators of this type have been analyzed for discrete-time channels, and we extend this analysis to continuous-time channels. We present analytical expressions for their mean-squared error (MSE) and eval

Possible human leukocyte antigen-mediated genetic interaction between type 1 and type 2 Diabetes

We assessed the prevalence of families with both type 1 and type 2 diabetes in Finland; and we studied, in patients with type 2 diabetes, the association between a family history of type 1 diabetes, glutamic acid decarboxylase (GAD) antibodies (GADab), and type 1 diabetes-associated human leukocyte antigen (HLA) DQB1-genotypes. Further, in mixed type 1/type 2 diabetes families, we investigated whe

Predictive markers for tamoxifen response in primary breast cancer

Popular Abstract in Swedish Bröstcancer är den vanligaste cancersjukdomen hos kvinnor i västvärlden och årligen nydiagnosticeras omkring 7000 patienter, bara i Sverige. Antalet nyinsjuknade ökar för varje år medan dödligheten sjunker och de främsta orsakerna till detta tros vara förbättrad diagnostik via mammografiscreening och nya behandlingsmöjligheter. Bröstcancer behandlas primärt med kirurgi,It is well-known that a majority of breast cancers are hormone-dependent, making endocrine therapy an important adjuvant treatment after surgery. Susceptibility to endocrine treatment is determined by the presence of estrogen receptors (ER) and progesterone receptors (PR) in the tumors. Tamoxifen is the most well-established endocrine treatment available, inhibiting tumor growth and improving surv

Seasonality extraction by function fitting to time-series of satellite sensor data

A new method for extracting seasonality information from time-series of satellite sensor data is presented. The method is based on nonlinear least squares fits of asymmetric Gaussian model functions to the time-series. The smooth model functions are then used for defining key seasonality parameters, such as the number of growing seasons, the beginning and end of the seasons, and the rates of growt

A web-based interactive virtual environment for mobile phone customization

With globalization, more and more companies are becoming multisited. Efficient and timely collaboration and communication among the development team members become critical for product success. This paper proposes a web-based virtual environment for mobile phone customization, named VMPDS (Virtual Mobile Phone Design Space). The features of this system include the combination of web technology and

Long-term exposure to glucose and lipids inhibits glucose-induced insulin secretion downstream of granule fusion with plasma membrane.

Mouse beta-cells cultured at 15 mmol/l glucose for 72 h had reduced ATP-sensitive K+ (K-ATP) channel activity (-30%), increased voltage-gated Ca2+ currents, higher intracellular free Ca2+ concentration ([Ca-i(2+]) +160%), more exocytosis (monitored by capacitance measurements, +100%), and greater insulin content (+230%) than those cultured at 4.5 mmol/l glucose. However, they released 20% less ins

A novel interaction between type IV pili of Neisseria gonorrhoeae and the human complement regulator C4B-binding protein

C4b-binding protein (C4BP) is an important plasma inhibitor of the classical pathway of complement activation. Several bacterial pathogens bind C4BP, which may contribute to their virulence. In the present report we demonstrate that isolated type IV pili from Neisseria gonorrhoeae bind human C4BP in a dose-dependent and saturable manner. C4BP consists of seven identical alpha-chains and one beta-c
