In humans, hyperventilation (HV) has various effects on systemic physiology and, in particular, on neuronal excitability and synaptic transmission. However, it is far from clear how the effects of HV are mediated at the cortical level. In this study we investigated the effects of HV-induced hypocapnia on primary motor (M1) and visual cortex (V1) excitability. We used 1) motor threshold (MT) and...

BACKGROUND/AIM The signal-averaging (SA) technique is used to record high-resolution electrocardiograms (HRECGs) showing cardiac micropotentials. We aimed to develop a non-invasive signal-averaging-based portable bedside device to determine His-ventricle interval. PATIENTS AND METHODS After amplifying the HRECG recordings, signal duration and voltage can be measured up to four decimal precisi...

Aim: The aim of this study is to investigate the effectiveness and reliability Tripod Index (TI) in defining hallux valgus (HV) deformity accompanying deformities evaluating treatment outcome. Material Methods: Fifty fifty two patients were included who underwent Chevron (group 1) proximal dome 2) osteotomy, respectively. Preoperative postoperative angle (HVA), intermetatarsal (IMA), Meary (MA)...

Fetal behavior, renal sympathetic nerve activity (RSNA), mean arterial pressure (MAP), and heart rate (HR) were studied 1-3 days after surgery in seven fetal sheep (aged 127-136 days). Five behavioral states were defined from chart recordings of electrocortical (electrocorticographic; ECoG) activity and eye, limb, and breathing movements. Most records were of high-voltage ECoG (HV) or low-volta...

A full-length cDNA (Hv-GR) whose transcript accumulation increased in response to infection by Blumeria graminis DC.f.sp. tritici (Bgt) was isolated from Haynaldia villosa. Southern analysis revealed a single copy of Hv-GR present in H. villosa. This gene encodes a glutathione reductase (GR) with high similarity to chloroplastic GRs from other plant species. Chloroplastic localization of Hv-GR ...

Aim: To compare the effects of various levels of acidic pH on surface microhardness of Biodentine.TM Materials and methods: Biodentine was mixed and packed into stainless steel molds (diameter = 5 mm and height = 1.5 mm). Four groups of 10 specimens each were formed and exposed to pH: 7.4, 6.4, 5.4 and 4.4 respectively for 4 days. Vickers microhardness was measured for each of the specimens and...

UNLABELLED The effects of high-volume cardioplegia on the presence of small-amplitude electrical activity during cardioplegia arrest were investigated in 19 mongrel dogs. The animals were randomly assigned to receive either high-volume crystalloid cardioplegia (HV-plege) or crystalloid cardioplegia guided by continuous electrical monitoring (V-plege). Cardiac index, left ventricular stroke work...

Eclipsing binaries in the Magellanic Clouds. ⋆ uvby CCD light curves and photometric analyses for Abstract. We present new accurate CCD uvby light curves for the LMC eclipsing binaries HV982 and HV12578, and for the SMC systems HV1433 and HV11284 obtained at the Danish 1.5m telescope at ESO, La Silla. The light curves were derived from DoPHOT photometry, and typical accuracies are between 0.007...
