Local antibiotic delivery in the form of antibiotic powder, irrigation solutions, bone cement, collagen sponges, pastes, and bone graft have complications including seromas, ototoxicity, nephrotoxicity, and compromised osteoblast activity [15]. There is a need in orthopedics to provide a longer-...
Non-woven fabrics are used in the manufacture of products such as washing and wiping cloths, diapers, sanitary napkin covers, hospital gowns, surgical drapes, sheets, pillow cases, curtains, backing material for garments, table cloths, bed spreads, sponges, underpads, etc. For these products and...
mutansbiofilms grown on either plastic dishes or on collagen membrane and assayed by CFU, live-dead staining using confocal microscopy, transmission electron microscopy and H&E staining for collagen films. Cytotoxicity and subcellular localization was studied in human fibroblasts. Sponges of bioabsorbable...
Ascorbic acid, a well-known antioxidant, provides a useful positive control substance for comparative purposes. Freeze-dried sponges of chitin/chitosan and hydroxyethyl cellulose were used as negative controls. Application of this test resulted in DPPH test values of 80-90% for the positive control ...

Marine sponges are multi-cellular filter-feeding invertebrates that harbour various bacteria, representing approximately 41 known phyla [2,3]. These sponge-derived bacteria are responsible for a series of functional metabolic activities, including antibacterial, antifungal, anti-tumour, and anti-infective ...
could kill Burkitt lymphoma and U937 cells in vitro, as well as Ehrlich ascites carcinoma cells in vivo [3,29]. A variable level of toxicity with different LC50values (850.1, 142.1, 9.5, and 6.4 μg/mL) was also observed in lectins purified from marine sponges and a sea cucumber [30,...
To prevent the colonization of bacterial wounds, different wound dressings have been developed, with both natural and synthetic materials in the form of sponges, hydrogels hydrocolloids, films, or membranes and, as might be expected, each of these approaches has advantages and disadvantages [3]. ...
They involve the direct immersion of contaminated pieces of test material (e.g., cubes, sawdust, shavings) or a collection device (e.g., swabs, sponges) in an eluent (sterilized phosphate buffer saline or peptone water) and then a physical dissociation method such as shaking, sonication, ...
Marine sessile organisms, such as algae, sponges and corals, have developed physiological adaptations, including the synthesis of bioactives which confer defense against grazers and/or the installation of epiphytes and fouling organisms [1,2,3]. Metabolites from green, brown and red marine algae may...
