No full textRole of mushroom polysaccharides in improving gut health and associated diseases
No full textMushrooms have been widely used for nutritional and therapeutic purposes for over a millennium. Medicinal mushrooms have the potential to stimulate the gut microbiota by functioning as immunomodulators. However, mushrooms’ health-promoting attributes through regulation of the gut microbiota have not been thoroughly studied. This chapter provides information on the health-promoting properties of medicinal mushrooms in regulating the gut microbiota and the mechanisms by which mushrooms improve host health through their prebiotic potential. Mushrooms are rich in dietary fibers such as chitin, galactans, α- and β-glucans, mannans, and xylans. These indigestible mushroom polysaccharides contribute as an excellent source of prebiotics and prevent the proliferation of opportunistic pathogens, promote the growth of probiotic bacteria, and restore the bacterial imbalance in the gastrointestinal tract. Mushrooms polysaccharides have also been shown to enhance the antioxidant status by improving microbiome diversity in the gut. The explicit mechanisms of the polysaccharide constituents that are present in mushrooms that are responsible for prebiotic potential and gut microbiota modulation need further study
Nutraceuticals from microalgae
No full textNutraceuticals have been defined as food or food products that can simultaneously provide nutrition and pharmaceutical benefits to the body such as prevention and treatment of diseases (Borowitzka 2013). According to the US Institute of Medicine, this includes “any substance that is a food or part of a food which provides medicinal or health benefits including the prevention and treatment of disease, beyond the traditional nutrients it contains” (Burja and Radianingtyas 2008). They have also been termed as food supplements by the US Food and Drug Administration. Another synonymous term used is functional foods that have been defined as “products derived from natural sources, whose consumption is likely to benefit human health and enhance performance” (Burja and Radianingtyas 2008). This may include the fortification of conventional food to increase its nutritional or health benefit. Nutraceuticals can be either a whole food product (e.g. seaweed) or dietary supplements where the nutraceutical compound(s) may be concentrated to provide the claimed health benefits (e.g. Haematococcus in powder or tablet form or astaxanthin extract)
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
