In a search for molecular markers providing both informative diagnostics of malignant disease, and rational stratification of a therapeutic strategy to achieve optimal response in a given patient, we examined the possibility of using telomerase for this purpose in colorectal cancer. Telomerase, a ribonucleoprotein enzyme complex catalysing synthesis of(More)
It has been proven that the improper function of the vocal folds can result in perceptually distorted speech that is typically identified with various speech pathologies or even some neurological diseases. As a consequence, researchers have focused on finding quantitative voice characteristics to objectively assess and automatically detect non-modal voice(More)
The automatic recognition of MP3 compressed speech presents a challenge to the current systems due to the lossy nature of compression which causes irreversible degradation of the speech wave. This article evaluates the performance of a recognition system optimized for MP3 compressed speech with current state-of-the-art acoustic modelling techniques and one(More)
The paper analyses suitable features for distorted speech recognition. The aim is to explore the application of command ASR system when the speech is recorded with far-distance microphones with a possible strong additive and convolutory noise. The paper analyses feasible contribution of basic spectral subtraction coupled with cepstral mean normalization in(More)
In clinical practice, the severity of disordered voice is typically rated by a professional with auditory-perceptual judgment. The present study aims to automate this assessment procedure, in an attempt to make the assessment objective and less laborintensive. In the automated analysis, glottal airflow is estimated from the analyzed voice signal with an(More)
This study analyzes signals recorded using a neck-surface accelerometer from subjects producing speech with different voice modes. The purpose is to explore if the recorded waveforms can capture the glottal vibratory patterns which can be related to the movement of the vocal folds and thus voice quality. The accelerometer waveforms do not contain the(More)
The performance of speech recognition systems can be significantly degraded if the speech spectrum is distorted. This includes situations such as the usage of an improper recording device, enhancement technique or speech coder. This paper presents a front-end compensation method called spectrally selective dithering aimed at reconstructing the spectral(More)
Ro 13-7410 was given to 29 patients (a total of 38 treatment courses) for 7.5 weeks (range 4-23). This compound is one of the most potent retinoids ever synthetized and has the highest affinity to human skin cellular retinoic-acid-binding protein. At therapeutically active doses, it did not induce the commonly seen mucocutaneous signs of retinoid toxicity(More)
