Survey of oviducal gland structure and function in elasmobranchs
A comparative survey of the structure and function of oviducal glands of selected elasmobranch fish with differing modes of reproduction using light and scanning electron microscopy finds that the capsule-producing OG the authors studied seems to use the same basic assembly process to produce tough, flexible, and selectively permeable egg capsules, candles, or egg envelopes.
Determination of the elastic modulus of native collagen fibrils via radial indentation
The authors studied the elastic response of single, native collagen fibrils extracted from tissues of the inner dermis of the sea cucumber, Cucumaria frondosa, via local nanoscale indentation with an
Viscoelastic shear properties of articular cartilage and the effects of glycosidase treatments
The results suggest that the ability of collagen to resist tension elastically provides the stiffness of the cartilage matrix in shear and its elastic energy storage capability.
Material properties and biochemical composition of mineralized vertebral cartilage in seven elasmobranch species (Chondrichthyes)
Ver vertebral cartilage was found to be as stiff and strong as mammalian trabecular bone and a significant predictor of material properties.
Site‐related variations in glycosaminoglycan content and swelling properties of bovine flexor tendon
The results suggest that the articulating layer of distal flexor tendon is adapted for a unique set of mechanical requirements and that an elevated proteoglycan content at the site of compressive and frictional forces contributes to meeting these functional needs.
Biological properties of dehydrated human amnion/chorion composite graft: implications for chronic wound healing
PURION® processed dHACM retains its biological activities related to wound healing, including the potential to positively affect four distinct and pivotal physiological processes intimately involved in wound healing: cell proliferation, inflammation, metalloproteinase activity and recruitment of progenitor cells.
The notochord of hagfish Myxine glutinosa: visco-elastic properties and mechanical functions during steady swimming.
As the body's primary source of EI and C, the notochord determines the passive mechanical behavior of the swimming hagfish, and the ratio of stiffness to damping moments, also known as the amplification ratio at resonance, is nearly invariant with changes in driving frequency.
Collagen and proteoglycan in a sea urchin ligament with mutable mechanical properties
The collagen fibrils of the spine ligament of the pencil urchin Eucidaris tribuloides are discontinuous and end by tapering within the body of the ligament, which is consistent with the “sliding fibril” hypothesis and suggest that the proteoglycan may be an important component of the stress-transfer matrix.
