Staining-free malaria diagnostics by multispectral and multimodality light-emitting-diode microscopy.

We report an accurate optical differentiation technique between healthy and malaria-infected erythrocytes by quasi-simultaneous measurements of transmittance, reflectance, and scattering properties of unstained blood smears using a multispectral and multimode light-emitting diode microscope. We propose a technique for automated imaging, identification, and counting of malaria-infected erythrocytes

An indirectly pumped terahertz quantum cascade laser with low injection coupling strength operating above 150 K

We designed and demonstrated a terahertz quantum cascade laser based on indirect pump injection to the upper lasing state and phonon scattering extraction from the lower lasing state. By employing a rate equation formalism and a genetic algorithm, an optimized active region design with four-well GaAs/Al0.25Ga0.75As cascade module was obtained and epitaxially grown. A figure of merit which is defin

Heat Shock Protein 70 Reduces alpha-Synuclein-Induced Predegenerative Neuronal Dystrophy in the alpha-Synuclein Viral Gene Transfer Rat Model of Parkinson's Disease

AimsIt has become increasingly evident that the nigrostriatal degeneration associated with Parkinson's disease initiates at the level of the axonal terminals in the putamen, and this nigrostriatal terminal dystrophy is either caused or exacerbated by the presence of -synuclein immunopositive neuronal inclusions. Therefore, strategies aimed at reducing -synuclein-induced early neuronal dystrophy ma

Upper limits on a stochastic gravitational-wave background using LIGO and Virgo interferometers at 600-1000 Hz

A stochastic background of gravitational waves is expected to arise from a superposition of many incoherent sources of gravitational waves, of either cosmological or astrophysical origin. This background is a target for the current generation of ground-based detectors. In this article we present the first joint search for a stochastic background using data from the LIGO and Virgo interferometers.

Glucose transport machinery reconstituted in cell models.

Here we demonstrate the production of a functioning cell model by formation of giant vesicles reconstituted with the GLUT1 glucose transporter and a glucose oxidase and hydrogen peroxidase linked fluorescent reporter internally. Hence, a simplified artificial cell is formed that is able to take up glucose and process it.

The role of pain and functional impairment in the decision to recommend total joint replacement in hip and knee osteoarthritis: an international cross-sectional study of 1909 patients. Report of the OARSI-OMERACT Task Force on total joint replacement

Objective: To assess the pain and functional disability levels corresponding to an indication for total joint replacement (TJR) in hip and knee osteoarthritis (OA). Methods: Design: International cross-sectional study in 10 countries. Patients: Consecutive outpatients with definite hip or knee OA attending an orthopaedic outpatient clinic. Gold standard measure for recommendation for TJR: Surgeon'

Vaccine for Atherosclerosis.

Atherosclerosis is an immune-mediated inflammatory disease of the arterial wall, with both the innate and adaptive immune systems responding to many endogenous and exogenous antigens. Both proatherogenic as well as atheroprotective roles have been identified for the immune system in atherosclerosis. Hence, it is conceivable that an immunomodulatory strategy via active immunization against many of

Review on mechanisms and continuum models of multi-phase transport phenomena in porous structures of non-aqueous Li-Air batteries

During recent years intensive research activities involving both experimental and modeling approaches have appeared for different aspects of Lithium-air (Li-air) battery. Multi-phase transport phenomena including dissolved oxygen and lithium ions (Lit) in the liquid electrolyte, as well as electrons in the solid materials, are strongly coupled with the porous structures and various reactions, part

Pericytes contribute to airway remodeling in a mouse model of chronic allergic asthma

Myofibroblast accumulation, subepithelial fibrosis, and vascular remodeling are complicating features of chronic asthma, but the mechanisms are not clear. Platelet-derived growth factors (PDGFs) regulate the fate and function of various mesenchymal cells and have been implicated as mediators of lung fibrosis. However, it is not known whether PDGF-BB signaling via PDGFR beta, which is critical for

H-2 vertical profiles in the continental boundary layer : measurements at the Cabauw tall tower in The Netherlands

In-situ, quasi-continuous measurements of atmospheric hydrogen (H-2) have been performed since October 2007 at the Cabauw tall tower station in the Netherlands. Mole fractions of H-2, CO and several greenhouse gases are determined simultaneously in air sampled successively at four heights, between 20 and 200 m above ground level. Rn-222 measurements are performed in air sampled at 20 and 200 m. Th

An Evolutionary Adaptation of the Fall

According to John Polkinghorne, the Fall is the major Christian doctrine that is the most difficult to reconcile with contemporary science. Like him, however, I believe it is vitally important, even in this regard, to try to pinpoint the extent to which taking science seriously requires us to modify traditionally held beliefs. In this paper I focus on two problematic ideas associated with the Fall

A Continuum Theory of Phase Separation Kinetics for Active Brownian Particles

Active Brownian particles (ABPs), when subject to purely repulsive interactions, are known to undergo activity-induced phase separation broadly resembling an equilibrium (attraction-induced) gas-liquid coexistence. Here we present an accurate continuum theory for the dynamics of phase-separating ABPs, derived by direct coarse-graining, capturing leading-order density gradient terms alongside an ef

Biogeography of bacterial communities exposed to progressive long-term environmental change

The response of microbial communities to long-term environmental change is poorly understood. Here, we study bacterioplankton communities in a unique system of coastal Antarctic lakes that were exposed to progressive long-term environmental change, using 454 pyrosequencing of the 16S rDNA gene (V3-V4 regions). At the time of formation, most of the studied lakes harbored marine-coastal microbial co

Leisure repertoire among persons with a spinal cord injury: Interests, performance, and well-being

Objective: To explore and describe the leisure repertoire of persons with traumatic spinal cord injury (SCI) and how the repertoire is related to interest, performance, and well-being. Design: Cross-sectional study. Setting: A total of 97 persons with traumatic SCI were recruited from the non-profit national organization, RG Active Rehabilitation in Sweden. Outcome measure: Data were collected thr

Discriminating and Simulating Actions with the Associative Self-Organizing Map

Abstract in UndeterminedWe propose a system able to represent others' actions as well as to internally simulate their likely continuation from a partial observation. The approach presented here is the first step towards a more ambitious goal of endowing an artificial agent with the ability to recognise and predict others' intentions. Our approach is based on the associative self-organising map, a

Connecting Inflammation with Glutamate Agonism in Suicidality

The NMDA-receptor antagonist ketamine has proven efficient in reducing symptoms of suicidality, although the mechanisms explaining this effect have not been detailed in psychiatric patients. Recent evidence points towards a low-grade inflammation in brains of suicide victims. Inflammation leads to production of quinolinic acid (QUIN) and kynurenic acid (KYNA), an agonist and antagonist of the glut
