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

The genetics of migration on the move.

Across a range of organisms, related species or even populations of the same species exhibit strikingly different scales and patterns of movement. A significant proportion of the phenotypic variance in migratory traits is genetic, but the genes involved in shaping these phenotypes are still unknown. Although recent achievements in genomics will evolve migratory genetics research from a phenotypic

Measuring disease activity in adults with systemic lupus erythematosus: the challenges of administrative burden and responsiveness to patient concerns in clinical research.

Measuring lupus disease activity accurately remains a challenging and demanding task given the complex multi-system nature of lupus, an illness known for its variability between patients and within the same patient over time. Many have attempted to define what disease activity means and how it should be measured, and several instruments were devised for a standardized assessment of disease activit

How do people with cognitive functional limitations post-stroke manage the use of buses in local public transport?

Abstract in UndeterminedPeople with cognitive functional limitations (CFLs) have rarely been the focus of research dealing with road users and their needs. The aim of the present study was to describe how people with CFL post-stroke manage in their use of buses in the framework of their outdoor mobility, and to find out what difficulties, but also what opportunities, they experienced when moving f

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

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.

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

Combining axial and radial nanowire heterostructures: Radial Esaki diodes and tunnel field-effect transistors

The ever-growing demand on high-performance electronics has generated transistors with very impressive figures of merit. The continued scaling of the supply voltage of field-effect transistors, such as tunnel field-effect transistors (TFETs), requires the implementation of advanced transistor architectures including FinFETs and nanowire devices. Moreover, integration of novel materials with high e

Probing the Anisotropic Distortion of Photoexcited Spin Crossover Complexes with Picosecond X-ray Absorption Spectroscopy

For numerous spin crossover complexes, the anisotropic distortion of the first coordination shell around the transition metal center governs the dynamics of the high-spin/low-spin interconversion. However, this structural parameter remains elusive for samples that cannot be investigated with crystallography. The present work demonstrates how picosecond X-ray absorption spectroscopy is able to capt

Ranking alternatives by a fair bidding rule: A theoretical and experimental analysis

We apply a procedurally fair rule to a situation where people disagree about the value of three alternatives in the way captured by the voting paradox. The rule allows people to select a final collective ranking by submitting a bid vector with six components (the six possible rankings of the three alternatives). We test experimentally the robustness of the rule to subsidies and taxes as well as to

Improved glycemic control induced by both metformin and repaglinide is associated with a reduction in blood levels of 3-deoxyglucosone in nonobese patients with type 2 diabetes

Objective: Metformin has been reported to reduce alpha-dicarbonyls, which are known to contribute to diabetic complications. It is unclear whether this is due to direct quenching of alpha-dicarbonyls or to an improvement in glycemic control. We therefore compared the effects of metformin versus repaglinide, an antihyperglycemic agent with an insulin-secreting mechanism, on the levels of the alpha-

Genotyping of human papillomavirus in triaging of low-grade cervical cytology.

OBJECTIVE: The objective of the study was to evaluate whether typing of human papillomavirus (HPV) among women with low-grade cervical cytology can improve the ability to identify women with cervical cancer or cervical intraepithelial neoplasia grade III (CIN III or worse). STUDY DESIGN: A total of 1595 women with low-grade cervical cytology participating in a randomized implementation trial of HP

Regioselective reductive openings of 4,6-benzylidene acetals: synthetic and mechanistic aspects.

The use of benzylidene acetals as protecting groups in carbohydrate chemistry is utterly important. The main advantage of benzylidene acetal is the ability for regioselective openings. 4,6-benzylidene acetal can be opened selectively under reductive conditions to yield either free 4-OH or 6-OH. There are a plethora of methods available for regioselective openings, but only a few of these are widel

Gender differences in biometry prediction error and intra-ocular lens power calculation formula

PurposeTo analyze changes over time in biometry prediction error (BPE) after cataract surgery with special reference to the impact of gender and the intra-ocular lens (IOL) calculation formula. MethodsAbout 65% of Swedish cataract surgery units participating in the outcome registration of the National Cataract Register (NCR) were included in this prospective register study. Data for planned and po

The crisis of a legal framework: Protection of victims of human trafficking in the Bulgarian legislation

The Council of Europe Group of Experts on Action against Trafficking in Human Beings reported that in Bulgaria no adult victim of human trafficking received any assistance and that no adult victim was granted a reflection period. A close examination of the Bulgarian legislative framework could explain this unpromising picture. In this article, I develop three arguments in relation to the Bulgarian

Please Be Patient : A Cultural Phenomenological Study of Haemodialysis and Kidney Transplantation Care

Popular Abstract in Swedish Avhandlingen undersöker de två behandlingsalternativ, hemodialys och njurtransplantation, som är tillgängliga för personer med njursvikt. I fokus för undersökningen står de former av person- och patientskap som skapas och upprätthålls i hemodialys- och njurtransplantationsvården samt i de njursjukas vardagsliv. Ett av avhandlingens grundläggande antaganden är att dessa This thesis examines the practice of haemodialysis and kidney transplantation, the two medical therapies available for persons with kidney failure, from a phenomenological perspective. A basic assumption made in the thesis is that contemporary biomedicine is deeply embedded in the cultural, historical, economic, and political circumstances provided by the particular local, national, and transnatio
