Our objective was to determine if condensed tannin extract from quebracho trees (Schinopsis quebracho-colorado; red quebracho) could be used to reduce enteric methane emissions from cattle. The experiment was designed as a repeated 3 x 3 Latin square (4 squares) with 3 treatments (0, 1, and 2% of dietary DM as quebracho tannin extract) and 3 28-d periods.(More)
The evolution of digestive proteases during larval development of Rhynchophorus ferrugineus (Olivier, 1790) has been studied. A progressive increase of protease activity has been found. The optimum pH for proteolytic activity against azocasein was determined. Caseinograms revealed an active complex of alkaline proteases from the early stages of the(More)
To identify simple screening tools for selecting condensed tannin (CT)-containing forages as candidate sources for further study, CT were isolated from nine legumes, and their molecular weights (MW), chromophore production, capacity to precipitate bovine serum albumin (BSA) and Fraction 1 protein (Rubisco) isolated from alfalfa, and inhibition of filter(More)
BACKGROUND/AIMS To identify physician selection factors in the treatment of locally advanced head and neck cancer and how treatment outcome is affected by Tumor Board recommendations. METHODS A retrospective analysis of 213 patients treated for locally advanced head and neck cancer in a single institution was performed. All treatments followed Tumor Board(More)
BACKGROUND We would like to assess the safety and effectiveness of prophylactic percutaneous endoscopic gastrostomy (PEG) tube feedings during concurrent chemoradiation for head and neck cancer. METHODS Patients who underwent chemotherapy and radiation for head and neck malignancies were evaluated for their ability to resume oral feeding following(More)
UNLABELLED Platinum-based chemotherapy has been reported to induce diabetes and hyperosmolar coma in nondiabetic patients. The aim of the present study was to determine whether the administration of chemoradiation for head and neck carcinoma alters glucose metabolism during and after treatment. PATIENTS AND METHODS Weekly nonfasting serum glucose level(More)
The aim of this study was to evaluate the aspiration rate following nonsurgical therapy, i.e. chemoradiation or radiation alone for laryngeal cancer. Modified barium swallow was performed in 43 patients who complained of dysphagia following chemoradiation (n = 22) or radiation alone (n = 21) for laryngeal cancer. Patients were selected if they were cancer(More)
AIM To assess the risk of developing aspiration during chemoradiation for head and neck cancer. PATIENTS AND METHODS A retrospective review of 114 patients who underwent concurrent chemoradiation for locally advanced head and neck cancer was undertaken. Patients were determined as having aspiration if they had pneumonia on chest-X-ray (CXR) and/or had(More)
An improved method, based on sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) for detection of amylase activity is described. This method will allow better characterization of certain amylases than that obtained by the Davis technique. The main features of the technique are: (i) identification of amylase bands and molecular mass(More)
UNLABELLED The aim of the present study was to assess dysphagia severity following postoperative radiation for locally advanced oropharyngeal cancer. PATIENTS AND METHODS Eighteen patients with oropharyngeal carcinoma had undergone postoperative radiation. There were eight base of tongue, eight tonsils, and two soft palate carcinomas. All the patients had(More)
