Ultrastructural studies on the collagen of the marine sponge Chondrosia reniformis Nardo.
The ultrastructure of isolated fibrils of Chondrosia reniformis sponge collagen was investigated by collecting characteristic data, such as fibril thickness, width, D-band periodicity, and height modulation, using atomic force microscopy (AFM) and transmission electron microscopy (TEM). Therefore an adapted pre-processing of the insoluble collagen into homogeneous suspensions using neutral buff...
متن کاملMechanical adaptability of a sponge extracellular matrix: Evidence for cellular control of mesohyl stiffness in Chondrosia reniformis Nardo.
The marine sponge Chondrosia reniformis Nardo consists largely of a collagenous tissue, the mesohyl, which confers a cartilaginous consistency on the whole animal. This investigation was prompted by the incidental observation that, despite a paucity of potentially contractile elements in the mesohyl, intact C. reniformis stiffen noticeably when touched. By measuring the deflection under gravity...
متن کاملBiosurfactant production from marine bacteria associated with sponge Callyspongia diffusa
Marine-derived biosurfactants have gained significant attention due to their structural and functional diversity. Biosurfactant production was performed using bacteria associated with Callyspongia diffusa, a marine sponge inhabiting the southern coast of India. A total of 101 sponge-associated bacteria were isolated on different media, of which 29 isolates showed positive result for biosurfacta...
متن کاملStudy of L-Asparaginase Production by Streptomyces noursei MTCC 10469, Isolated from Marine Sponge Callyspongia diffusa
L-asparaginase is an anti-neoplastic agent used in the chemotherapy of lymphoblastic leukaemia. The present work deals with production of extra-cellular Lasparaginase from marine actinomycetes, using submerged fermentation. Marine actinomycete Streptomyces associated with marine spongeCallyspongia diffusa was isolated using specific ISP medium. Sponge-associated Streptomyces was character...
متن کاملCalcium Oxalate Calculus in the Urethra
A male, aged about 40 years, employed as a ' line' chowkidar, was admitted into the hospital on the 7th September, 1936, with the following symptoms :? Frequency of micturition for one year, the quantity passed on each occasion being very small and pain and irritability of the glans penis. These symptoms had become much worse during the past four or five days. There was a slight muco-purulent d...
