This study investigates neural processes underlying audiovisual perception of a non-native vowel contrast using fMRI. Eight native Japanese and eight native English speakers participated in the study. The two-alternative forced choice task was to identify which vowel was present in the CVC English word presented under audiovisual (AV) and audio only (AO) conditions. Three sessions were conducte...

در این تحقیق، با استفاده از مدل واندرپل، تحلیل همزمانی دو پیس میکر اصلی قلب به نامهای گره سینوسی- دهلیزی (sa) و گره دهلیزی- بطنی (av) در شرایط مختلف از جمله تزویج یکطرفه و دوطرفه و در نظر گرفتن یا صرفنظر کردن از تاخیر با دو روش تابع توصیف و آشفتگی مورد بررسی قرار می گیرد. اگرچه پارامترهای مدل واندرپل مستقیماً متناظر با کانال های یونی سلولها نمی باشند ولی مدل واندرپل، مدل مناسبی برای گره های sa و...

Introduction: Ouabaine is a well-known atrioventricular (AV) node depressant agent, but its effects on functional properties of the AV node have not been cleared. The aim of the present study was to determine how ouabaine administration modifies the rate-dependent properties of the AV node. Methods: Selective stimulation protocols were used to quantify independently electrophysiological prop...

Introduction: Recent studies showed that nitrergic system have specific modulatory effects on electrophysiological properties of atrioventricular (AV) node. The aim of this study was to determine the effects of nitric oxide (NO) on the electrophysiological properties of isolated rabbit AV node and to investigate the role of adrenergic and cholinergic receptors in the mechanism of its action...

This paper compares three net art projects combining sound and animation by the author and André Carrilho (under the name Video Jack): AVOL, Master and Margarita and AV Clash. They follow a development path aiming to create projects enabling integrated audiovisual creativity that are flexible, intuitive, playful to use and engaging to experience. The comparative evaluation of the projects focus...

Background & Objective: To find an association between gene variants of insulin-like growth factor-1 (IGF-1) and 5,10-methylenetetrahydrofolate reductase (MTHFR) with the risk of acne vulgaris (AV). Methods: In a case-control study, we investigated 150 AV patients and 148 healthy individuals (aged 18-25 years) for the IGF-1 G>A and MTHFR C677T polymorphis...

Although β-amyloid (Aβ) may be the primary driver of Alzheimer's disease (AD) pathology, accumulation of pathological tau correlates with dementia in AD patients. Thus, the prevention/inhibition of AD may require vaccine/s targeting Aβ and tau simultaneously or sequentially. Since high antibody titers are required for AD vaccine efficacy, we have decided to generate vaccines, targeting Aβ (AV-1...
