  • Optimal conditions for the extraction of black fungus polysaccharides were 350 W, 5, 35 min and 90 ◦C, for ultrasonic power, ratio of water to sample, extraction time and extraction temperature, respectively. Gas chromatography (GC) analysis showed that black fungus polysaccharides contained glucose, xylose, mannose and ribose. Their molar percentages were 6.8%, 34.2%, 50.7% and 8.9%, respectively. FT-IR and NMR analysis showed typical chemical structure of black fungus polysaccharides.

  • In this document, we present a language which associates type construction principles to constraint logic programming. We show that it is very appropriate for language processing, providing more uniform, expressive and efficient tools and treatments. We introduce three kinds of constraints, that we exemplify by motivational examples. Finally, we give the procedural semantics of our language, combining type construction with SLDresolution.

  • Factors predisposing to colorectal cancer in UC patients consist of pancolitis, duration of disease, active disease and its severity. Early UC onset is another independent risk factor. Beside these factors, dysplasia represents the precancerous lesion from which colorectal cancer subsequently arise (Morson, 1962; Morson & Pang, 1967). In fact, 70% of patients with colorectal cancer on UC have dysplasia on colorectal mucosa (Taylor et al., 1992; Connell et al., 1994).

  • Shiitake mushroom contains several therapeutic actions such as antioxidant and antimicrobial properties, carried by the diversity of its components. In the present work, extracts from shiitake mushroom were obtained using different extraction techniques: high-pressure operations and low-pressure methods. The high-pressure technique was applied to obtain shiitake extracts using pure CO2 and CO2 with co-solvent in pressures up to 30 MPa.

  • Over the past 25 years the discipline of ecotoxicology has undergone two major developments. Firstly, new assays have been developed, deploying organisms that bear added relevance to the specific environment under investigation. Several new procedures assess the effects on organisms after exposure to environmental samples rather than to spiked water or sediment samples. Also noteworthy is the considerable attention given to effects of chronic exposure to low levels of contaminants.

  • Dyspnea is the subjective sensation of uncomfortable or difficult breathing. Most patients report dyspnea as "shortness of breath." Patients report dyspnea when their breathing is excessive for the activity that they are doing. The sensation of dyspnea is produced by stimulation of both central and peripheral receptors that monitor respiratory muscle activity, hypoxia, hypercapnia, acid-base status, airway irritation, and changes in the pressure volume characteristics of the lung (i.e., j receptors in lung fibrosis or emphysema).
