The pharmacological basis of perceptual learning and associated cortical reorganizations remains elusive. We induced perceptual learning by Hebbian coactivation of the skin of the tip of the right index finger in humans. Under placebo, tactile two-point discrimination was improved on the coactivated but not on the left index finger. This augmentation was blocked by an N-methyl-D-aspartate-recep...

For image transmission over noisy channels, the VQ paradigm is a strong competitor. We propose a post-processing scheme able to improve the perceptual quality of the VQ reconstructed image, for various types of noisy channels, when it is combined with an appropriate index assignment. For binary symmetric channels, we use the index assignment resulting from the LBG design of the codebook, which ...

Abstract Funding Acknowledgements Type of funding sources: None. Background Acute pulmonary thromboembolism (PE) is a life-threatening condition and an early diagnosis adequate therapy are critical. Mortality in PE still remains very high spite progress diagnostic tools. Several parameters for risk stratification have been reported with variable importance on clinical practice. Purpose To compa...

Aim: The aim of this study is to evaluate and compare the values of strain index ratio as measured by real-time ultrasound elastography in healthy subjects and in adolescent patients with Hashimoto Thyroiditis (HT). Our aim is also to determine cut-off value of strain index ratio, obtain reference values and evaluate if we can use this values in diagnosis and follow-up. Material and methods: A ...

To the Editor We read the case report by Baha et al. (1) in the latest issue of Internal Medicine with great interest. In this case report, a patient with massive pulmonary embolism (PE) confirmed by thorax computed tomography (CT) angiography was successfully treated with thrombolytic therapy. Massive PE can lead to cardiac arrest (CA) in 41% of patients, and the mortality rate was reported to...

Purpose: The GRBAS (grade, roughness, breathiness, asthenia, strain) scale, a 4-point has been most widely used for judging auditory-perceptual severity dysphonia. However, in current clinical practice, sometimes more fragmented 0.5 scheme is being if the original scale ambiguous to assess. Thus, aim of present study was compare dysphonia using three evaluation tools, 4-point, 7-point and CAPEV...
