Abstract:

Limb postures of terrestrial tetrapods span a continuum from sprawling to fully upright; however, most experimental investigations of locomotor mechanics have focused on mammals and ground-dwelling birds that employ parasagittal limb kinematics, leaving much of the diversity of tetrapod locomotor mechanics unexplored. This study reports measurements of in vivo locomotor strain from the limb bones of lizard (Iguana iguana) and crocodilian (Alligator mississippiensis) species, animals from previously unsampled phylogenetic lineages with non-parasagittal limb posture and kinematics.

Abstract:

Residual limb pain is defined as a painful sensation or feeling from the remaining part of the leg. Aggressive bone edge, bone spur formation, neuroma, abscess or bursitis are common causes of residual limb pain. On the other hand, regional osteoporosis on femur and tibia is an inevitable consequence in patients with lower limb amputations. The etiology of bone loss is uncertain but it is likely to be a local phenomenon in lower limb amputees. Altered gait pattern, decreased weight load, disuse atrophy and lack of muscular action at the limb seem to be important causal factors in the developme

Abstract:

Congenital vascular bone syndrome (CVBS) is an abnormal enhancement or reduction of growth in long bones due to pathologic circulation during childhood. Several authors have described these clinical pictures with limb lengthening; well known are Klippel and Trenaunay and Parkes-Weber. Later, Servelle and Martorell also described cases of limb length difference, but with shortening of the pathologic limb. The mechanism of limb overgrowth is probably due to the effect of A-V shunts, while shortening occurs due to mechanical compression on bones by dysplastic vessels or flow reduction. Some molec

Abstract:

Animal bones discarded by people are commonly subject to disturbance by carnivores. These carnivores are present throughout the world and include wolves, coyotes, hyenas, and many others. This disturbance not only modifies and destroys bone, but also moves many of the bone fragments away from their original position of discard. Intrasite spatial analyses of bone that seek patterns meaningful to human behavior thus need to subtract the effect of carnivore disturbance. Experimental studies with spotted hyenas show that the position of a bone fragment on a limb bone, combined with bone surface mo

AbstractThe robusticity of the weight-bearing limbs of large terrestrial animals is expected to increase at a more rapid rate than in their smaller relatives.

Curvilinear scaling has previously been found in mammals and nonavian theropods but has not been demonstrated in birds.

Yet all of this diversity arises from embryonic skeletal elements that are each a very similar size at formation.

Abstract:

Abstract Objectives Osteoporosis is a major health problem in the elderly characterized by bone loss and micro-architectural deterioration of bone tissue and associated with an increased risk of fracture. Prolonged bed rest, or physical inactivity during space flight causes rapid and marked bone loss. The effects of catechin, the main ingredient of Japanese green tea, on the bone are currently under study. It has been shown that green tea catechin modulates bone resorption in osteoclasts. However, there is no evidence supporting its inhibitory effect on bone loss during physical inactivity. In

Abstract:

Background Birds show adaptations in limb bone shape that are associated with resisting locomotor loads. Whether comparable adaptations occur in the microstructure of avian cortical bone is less clear. One proposed microstructural adaptation is laminar bone in which the proportion of circumferentially-oriented vascular canals (i.e., laminarity) is large. Previous work on adult birds shows elevated laminarity in specific limb elements of some taxa, presumably to resist torsion-induced shear strain during locomotion. However, more recent analyses using improved measurements in adult birds and ba

Abstract:

Testudines are a group of reptiles characterized by the presence of a shell covered by keratinous shields. Stigmochelys pardalis is the most widely distributed terrestrial testudine in southern Africa. Although relatively common with some life history traits being well known, the growth of this species has yet to be studied in any detail. The bone microanatomy of this clade differs from that found in other amniotes, where terrestrial species tend to display characteristics normally seen in aquatic species and vice versa. A detailed histological analysis of the limb bones of S. pardalis reveals

Abstract The objective of the study was to assess differences between the take-off and non-take-off limbs of athletes in track-and-field jumping events based on a segmental analysis of body composition as well as kinetic analysis. The research included 19 participants (10 males, 9 females) with an average age of 18.1 ± 2.8 years. We measured body height, body mass, body composition (body fat, fat free mass, bone mineral content and bone density) and segmental distribution of these variables. To assess strength of the lower limbs, we performed reaction force analysis during take-off and run sym

Methods The study included 45 male undergraduate students aged between 20 and 30 years. Total and segmental body composition, bone mineral density and bone mineral content assessments were performed using dual energy X-ray absorptiometry. Subjects were allocated into three groups (eutrophic, overweight and obese). Results With the exception of upper limb bone mineral content, significantly hi

Abstract:

Bone microstructure has long been known as a powerful tool to investigate lifestyle-related biomechanical constraints, and many studies have focused on identifying such constraints in the limb bones of aquatic or arboreal mammals in recent years. The limb bone microstructure of fossorial mammals, however, has not been extensively described. Furthermore, so far, studies on this subject have always focused on the bone histology of small burrowers, such as subterranean rodents or true moles. Physiological constraints associated with digging, however, are known to be strongly influenced by body si
