Excitotoxicity Downregulates TrkB.FL Signaling and Upregulates the Neuroprotective Truncated TrkB Receptors in Cultured Hippocampal and Striatal Neurons.
Brain-derived neurotrophic factor (BDNF) plays an important role in neuronal survival through activation of TrkB receptors. The trkB gene encodes a full-length receptor tyrosine kinase (TrkB.FL) and its truncated (T1/T2) isoforms. We investigated the changes in TrkB protein levels and signaling activity under excitotoxic conditions, which are characteristic of brain ischemia, traumatic brain injur

System Identification : A Survey
The field of identification and process-parameter estimation has developed rapidly during the past decade. In this survey paper the state-of-the-art/science is presented in a systematic way. Attention is paid to general properties and to classification of identification problems. Model structures are discussed; their choice hinges on the purpose of the identification and on the available a priori
Effects of Balloon Valvuloplasty on Coronary Blood Flow in Neonates With Critical Pulmonary Valve Stenosis Assessed With Transthoracic Doppler Echocardiography.
BACKGROUND: Treating pulmonary valve stenosis with balloon valvuloplasty (BV) is a good model to study the effect of right ventricular (RV) pressures on coronary flow. METHODS: Transthoracic Doppler echocardiography was used to register coronary flow in 10 age-matched healthy controls and 7 neonates before and 1 day after BV. RESULTS: Left ventricular fractional shortening and cardiac output incre
Challenges and considerations in diagnosing the kidney disease in deteriorating graft function.
Despite significant reductions in acute-rejection rates with the introduction of calcineurin inhibitor (CNI)-based immunosuppressive therapy, improvements in long-term graft survival in renal transplantation have been mixed. Improving long-term graft survival continues to present a major challenge in the management of kidney-transplant patients. CNIs are a key component of immunosuppressive therap
No direct effects of erythropoietin beta on a head and neck squamous cell carcinoma cell line which is growth stimulated in vivo.
Introduction. Erythropoiesis-stimulating agents (ESAs) are used in cancer therapy to reverse anaemia. It has been suggested that ESAs might improve treatment outcome by reducing tumour hypoxia, but ESAs might also increase tumour growth. In this work, the effect of recombinant human erythropoietin (rHuEpo) beta was investigated on a human head and neck squamous carcinoma cell (HNSCC) line in vitro

Industrial Emission Control Using Lidar Techniques
A mobile DIAL (differential absorption lidar) remote sensing system has been employed in the monitoring of industrial pollutant emissions. Measurements of sulfur dioxide and mercury vapor were performed at nine different Swedish industrial plants within the framework of a control program commissioned by the Swedish Environmental Protection Agency. Total atmospheric fluxes of these species could be
Newborn pain cry analysis based on pitch frequency tracking.
The aim of the newborn pain cry analysis is to test the hypothesis that cry can be used as a tool to detect signs of nocioceptive pain. Previous studies applying signal processing techniques to analyze the sound of these cries have been done. The subject of this paper is to adapt and improve the original method with the help of new signal processing methods. The pitch frequency is extracted from t

Visual Gender and Its Motivational and Cognitive Effects – a User Study
Cognitive and motivational effects of more neutral or androgynous-looking virtual characters versus more pronouncedly feminine-looking or masculine-looking virtual characters are explored. In a user study, 158 students aged 17-19 encountered four virtual characters that were visually manipulated to represent gender stereotypicality versus androgyny. One aim was to explore students’ attitudes towar
