The processing of spatio-temporal vibrotactile patterns by the torso was examined in two experiments. The first investigated the spatial acuity as function of location on the torso. A uniform acuity between 2 and 3 cm was found, except on the body midline where acuity was about 1 cm. This favorable effect was hypothesized to be caused by...

Background: Moderate alcohol consumption is associated with a decreased risk of cardiovascular disease. Because plasma homocysteine (tHcy) is considered an independent risk factor for cardiovascular disease and associated with alcohol consumption, the authors investigated the effect of moderate alcohol consumption on kinetics of plasma tHcy...

CEP-1347 is a potent inhibitor of the mixed lineage kinases (MLKs), a distinct family of mitogen-activated protein kinase kinase kinases (MAPKKK). It blocks the activation of the c-Jun/JNK apoptotic pathway in neurons exposed to various stressors and attenuates neurodegeneration in animal models of Parkinson's disease (PD). Microglial activation...

Osteopontin (OPN) has been identified as the most prominent cytokine-encoding gene expressed within multiple sclerosis (MS) lesions. Recently, we demonstrated that OPN plasma levels were elevated in active relapsing-remitting (RR) MS patients. In this longitudinal study, a trend was observed for OPN serum levels in relation to clinical...

This review's objective is to give a critical summary of studies that focused on physiologic measures relating to subjectively rated appetite, actual food intake, or both. Biomarkers of satiation and satiety may be used as a tool for assessing the satiating efficiency of foods and for understanding the regulation of food intake and energy...

In this longitudinal study, we examined the expression of Fas, FasL, CCR3, CCR5 and CXCR3 mRNA in peripheral blood mononuclear cells (PBMCs) of secondary progressive (SP) and relapsing-remitting (RR) multiple sclerosis (MS) patients. In RR patients, FasL, CCR3 and CCR5 mRNA levels were increased prior to the exacerbations, but these decreased...

The interactive use of magnetic resonance imaging (MRI) techniques is increasing in operating theaters. A study was performed on 17 male company volunteers to assess the neurobehavioral effects of exposure to magnetic fields from a 1.5 Tesla MRI system. The subjects' neurobehavioral performances on a neurobehavioral test battery were compared in...

This study examined motor control in 61 early and continuously treated patients with phenylketonuria (PKU) and 69 control participants, aged 7 to 14 years. The pursuit task demanded concurrent planning and execution of unpredictable movements, whereas the tracking task required a highly automated circular movement that could be planned in...

The family of Toll-like receptors (TLRs) plays a key role in controlling innate immune responses to a wide variety of pathogen-associated molecules. In this study we investigated expression of TLRs in vitro by purified human microglia, astrocytes, and oligodendrocytes, and in vivo by immunohistochemical examination of brain and spinal cord...

Background: Moderate alcohol consumption is associated with a reduced coronary heart disease (CHD) risk. Epidemiologic studies have provided conflicting data which suggests that CHD protection may be modulated or may not be modulated by a person's CHD risk profile. Methods: We examined the effects of moderate alcohol consumption (35 g/day) on...

HFC 134a (1,1,1,2-tetrafluoroethane) and HFC 227 (1,1,1,2,3,3,3-heptafluoropropane) are used to replace chlorofluorocarbons (CFCs) in refrigerant and aerosol applications, including medical use in metered-dose inhalers. Production and consumption of CFCs are being phased out under the Montreal Protocol on Substances that Deplete the Ozone Layer....

The present study examined the influence of ingesting a moderate dose of alcohol on plasminogen activator activity (t-PA), plasma fibrinogen (Fb), total degradation products (TDP) and the degradation products of fibrin (FbDP) and fibrinogen (FgDP) at rest and in response to exercise. Eleven male subjects performed two separate experimental...

The myelin-associated protein, αB-crystallin, is considered a candidate autoantigen in multiple sclerosis (MS). In the present study, we examined the potential of αB-crystallin to induce experimental autoimmune encephalomyelitis (EAE) in Lewis rats. Attempts to induce EAE with either bovine, rat or murine αB-crystallin or αB-crystallin peptides...

Relapsing experimental autoimmune encephalomyelitis (R-EAE) in the SJL mouse is a Th1-mediated autoimmune demyelinating disease model for human multiple sclerosis and is characterized by infiltration of the central nervous system (CNS) by Th1 cells and macrophages. Disease relapses are mediated by T cells specific for endogenous myelin epitopes...

Interactions between mononuclear cells are required for the formation of inflammatory infiltrates in the CNS and the activation of cellular effector functions provoking demyelination in MS. Membrane-expressed costimulatory molecules are crucial to such interactions. We therefore investigated whether two costimulatory molecules, CD40L (CD154,...

The pathogenesis of multiple sclerosis (MS), the major neurological disease of young adults in the Western world, is still poorly understood, and no effective therapy to block MS is available as yet. The clinical symptoms of MS result from inflammatory damage to the insulating myelin sheath of axons in the CNS and - at later stages - to axons...

Conclusion: Retinoids are suspected to have multiple functions during embryogenesis, which are carried out via various different signal transduction pathways involving active retinoids and nuclear retinoid receptors. Research focuses on the identification of the retinoid signal transduction components involved, and on their specific functions...

In a group of workers exposed to high levels of lead during five months nerve conduction velocity parameters were evaluated at the termination of exposure, and also three and fifteen months later. At the termination of exposure the mean blood lead level was 4.0 ??mol/l, and motor conduction velocities in the median and the ulnar nerves were...

Based on a preview-predictor model, the time-to-line crossing (TLC) description was developed to quantify the potential role of error-neglecting strategies in driving. In a previous study the usefulness of the TLC concept was illustrated for straight lane keeping. In the present analysis TLC was applied to describe steering through a curve. When...

The effects of CNS-active drugs and neurotoxic agents on motor coordination in the rat were studied using a newly developed, automated technique. In this test, a tv/microprocessor-based system was utilized to detect and describe the movement and placement characteristics of one of the rat's hindpaws as the rat placed its paw from one rung to...
