Subtropical China harbours the world's most diverse temperate flora, but little is known about the roles of geographical and eco-climatic factors underlying the region's exceptionally high levels of species diversity and endemism. Here we address this key question by investigating the spatio-temporal and ecological processes of divergence within the Dysosma versipellis-pleiantha species complex...
Postmenopausal women with vertebral fractures have abnormal bone microarchitecture at the distal radius and tibia by HR-pQCT, independent of areal BMD. However, whether trabecular plate and rod microarchitecture is altered in women with vertebral fractures is unknown. This study aims to characterize the abnormalities of trabecular plate and rod microarchitecture, cortex, and bone stiffness in p...
INTRODUCTION intramedullary nailing is a method of choice in the management of long bone diaphyseal fractures. However, complications necessitating re-operation may arise. This study was aimed at determining the rate and indications for re-operation following intramedullary nailing of tibia shaft fractures. METHODS it was a cross-sectional study done at Orthopaedic Department of Obafemi Awolo...
OBJECTIVE Proximal tibia fractures with metaphyseal comminution present a difficult treatment challenge. The Less Invasive Skeletal Stabilization (LISS) internal fixator system has theoretical advantages (minimally invasive fixed angle construct) for the treatment of these injuries. This report presents clinical results of the LISS system for treatment of complex proximal tibia fractures and il...
Patella: accounts for 1% of all fractures, most common in ages 20-50 Femoral condyles: these usually fracture when the knee is stressed. Tibial eminence: caused by accidents, such as a blow to the proximal tibia when the knee is flexed, or if the knee is hyperextended during an accident. Usually seen in patients aged 8-14. Tibial tuberosity: more common in men than in women, and in younger pati...
The atmospheric conditions above Dome A, a currently unmanned location at the highest point on the Antarctic plateau, are uniquely suited to astronomy. For certain types of astronomy Dome A is likely to be the best location on the planet, and this has motivated the development of the Plateau Observatory (PLATO). PLATO was deployed to Dome A in early 2008. It houses a suite of purpose-built site...
Despite recognition that nearly one-third of the 6300 amphibian species are threatened with extinction, our understanding of the general ecology and population status of many amphibians is relatively poor. A widely-used method for monitoring amphibians involves injecting captured individuals with unique combinations of colored visible implant elastomer (VIE). We compared VIE identification to a...
Groundwater plays a key role in maintaining the ecology and environment in the hyperarid Qaidam Basin (QB). Indirect evidence and data from sparse observation wells suggest that groundwater in the QB is increasing but there has been no regional assessment of the groundwater conditions in the entire basin because of its remoteness and the severity of the arid environment. Here we report changes ...
OBJECTIVES Osteogenesis imperfecta (OI) frequently leads to long-bone bowing requiring a surgical intervention in severe cases to avoid subsequent fractures. However, there are no objective criteria to decide when to perform such intervention. The objective is to develop a finite element model to predict the risk of tibial fracture associated with tibia deformity in patients with OI. METHODS ...
BACKGROUND & AIMS Children with cerebral palsy (CP) have a high prevalence of pathologic fractures. Bone quantitative ultrasonography (QUS) has emerged as a radiation-free method for the assessment of bone quality and fracture risk. In this study, we applied QUS technique in order to investigate bone status in handicapped institutionalized children and adolescents. METHODS This cross-sectiona...
