To assess the effect of diet enrichment with L-arginine or supplementation at high doses on physiological adaptation during exercise, 9 athletes followed 3 different diets, each over 3 consecutive days, with a wash-out period of 4 d between training sessions: control diet (CD), 5.5 +/- 0.3 g/d of L-arginine; Diet 1 (rich in L-arginine food), 9.0 +/- 1.1 g/d(More)
This work aims at gaining an insight into the mean and variance normalization technique (MVN), which is commonly used to increase the robustness of speech recognition features. Several versions of MVN are empirically investigated, and the factors affecting their performance are considered. The reported experimental work with real-world speech data (Speecon)(More)
Recently, the advantages of the spectral parameters obtained by frequency filtering (FF) of the logarithmic filter bank energies (logFBEs) have been reported. These parameters, which are frequency derivatives of the logFBEs, lie in the frequency domain, and have shown good recognition performance with respect to the conventional mel-frequency cepstral(More)
The aim of the study was to determine the effects of an antioxidant supplementation, which includes coenzyme Q(10), on plasma and neutrophil oxidative stress and the antioxidant response after a soccer match. Nineteen voluntary male pre-professional footballers were randomly and double-blinded treated with either a multivitamin and mineral supplement (n =(More)
PURPOSE To determine abnormalities in tear osmolarity (TO), tear function, and impression cytology in patients with pterygium and to assess the relationship between the variables. METHODS Thirty eyes from 30 patients with primary nasal pterygium and 30 eyes from 30 volunteers without ocular pathologies or dry eye symptoms were enrolled in the present(More)

PURPOSE To analyze the effects of tear hyperosmolarity on conjunctival cells in mild to moderate dry eye. METHODS Sixty-eight subjects (35 females and 33 males, mean age 43, S.D. 20.3, range 18-87 years) with symptoms of dry eye were enrolled in the study. Patients with severe dry eye or any other condition that induces ocular inflammation were excluded.(More)
PURPOSE To evaluate the relationship between ocular discomfort and pterygium clinical characteristics. METHODS The ocular comfort index test was self-completed by 25 men and 15 women (age [mean ± SD], 43 ± 11 years) with primary pterygium. Pterygium corneal area (PCA) and limbal perimeter, course and bilaterality of the lesion, visibility of episcleral(More)
PURPOSE To establish the sequence of tomographic changes in the tissue recovery process after pterygium excision and to propose healing indicators. METHODS Optical coherence tomography (OCT) images were taken at 1 week, 1, 3 and 6 months after lesion excision in 73 eyes of 73 patients (33 male, 40 female; mean age 50, S.D. 5.0, range 40-70 years) with(More)
