Abstract:
The Sailfin lizard is a lizard that has a semi-aquatic life and has a sail fin on its tail. These lizards can be found in habitats close to water such as rivers, lakes, and estuaries of mangrove forests. This study aimed to observe the morphofunctional characteristic of the appendicular skeleton of Sailfin Lizard (Hydrosaurus amboinensis), associated with their function and behavior. The appendicular skeleton of the Sailfin lizard was studied morphofunctional by observing and measuring the bones that make up the extremities. The naming of bones and their parts is based on the Nomina Anatomica

Abstract:
Mesenchymal progenitors within bone marrow have multiple differentiation potential and play an essential role in the maintenance of adult skeleton homeostasis. Mesenchymal progenitors located in bone regions other than the bone marrow also display bone-forming properties. However, owing to the differences in each distinct microenvironment, the mesenchymal characteristics of skeletal progenitor cells within different regions of long bones may show some differences. In order to clearly elucidate these differences, we performed a comparative study on mesenchymal progenitors from different regions

Abstract:
Sexual dimorphism is often considered to be the result of differences in the intensity of sexual selection between sexes. From this point of view, the sexual dimorphism of the limb bones of the Bufo gargarizans in southwest China was studied. Results showed that the fore- and hindlimb skeletons of this species were sexually dimorphic in anatomy. The humerus, radioulna, and total lengths of the forelimb skeleton of males were substantially longer than those of females, but the hand length of males was smaller than that of females. Several other features of males, such as deltoid and medial cres

Abstract During development, hematopoietic stem cells (HSCs) translocate from the fetal liver to the bone marrow (BM), which remains the site of hematopoiesis throughout adulthood. In the BM the HSCs are located at the endosteal surface, where cells of the osteoblastic lineage comprise a key component of the stem cell niche. While hematopoiesis occurs in many bones, the process of bone formation can actually be split into those bones that develop through endochondral ossification (long bones) and those that form through membranous ossification (flat bones).

The determination of the human or non-human origin of skeletal material can be particularly difficult if the bone is fragmented. It has been suggested that differences in the thickness of the cortical bone between human and non-human mammal long bones may be used to distinguish them, though little clear data exist. The aim of this thesis was to determine the extent of such difference, and whether it could be used to identify fragments of bone shafts.

Abstract:
Abstract Animal models are utilized in numerous research studies aimed at better understanding skeletal biology, bone biomechanics, and many orthopedic diseases or pathologies. Prominent among these animal models are rodents, most commonly rats and mice. In estimating bone mechanical properties in these animals, cortical bone is routinely assessed by bending one of the long bones such as the femur or tibia, which targets the mid-diaphysis region. Testing specimens of isolated cancellous bone is exceedingly challenging, however, even for the larger rat skeleton. Recognizing the prominence and i

Abstract:
Bone structure is exquisitely matched to its physical loading environment. From the cartilaginous skeletal framework formed in the embryo to the aging skeleton, bone architecture is directly related to function. Bone is a dynamic system, constantly remodeling itself by absorbing old tissue and forming new tissue. This capability allows bone architecture to become optimized to the loading environment. Julius Wolff [1] first postulated that bone structure adapts to changing stress environments in 1892. Exact understanding of the process of mechanotransduction, however, has remained elusive. In a

Abstract:
Direct measurements of cortical bone material properties are difficult to achieve in rodent long bones due to the inherently small dimensions and difficulties in machining standard test specimen geometries [1]. Bone tissue properties in nearly all rodent studies are thus limited to estimates from flexural tests of long bone diaphyses. In addition to the inaccuracies imposed by the bending stress state itself, these material property estimates are further confounded by the non-uniform geometry of long bones along the diaphyseal length. The goal of this work was to develop a series of techniques

During skeletal development, chondrocytes produce cartilage through differential cell growth, cell volume changes, and extracellular matrix secretion. Cartilage cells a

Studying the relationship between mechanical forces and skeletal development can provide vital clues to the mechanoregulation of skeletogenesis, providing important information to tissue engineers hoping to create functional cartilage or bone in vitro. Many studies of the mechanoregulation of skeletal development have focused on the chick embryo e.g., [1, 2]. However, as no endochondral ossification takes place in the embryonic chick long bones [1], mammalian systems must be used to examine the effect of mechanical forces on endochondral bone formation.

Abstract Bone Mineral Density (BMD) loss seen in astronauts can be simulated on Earth by prolonged horizontal bed rest. A device known as the Horizontal Exercise Machine (HEM) has been designed to test the effectiveness of heavy resistive exercise regimens for bed rest subjects. The objective of this project is to estimate the mechanical stress on the skeletal system due to various types of exercises and determine which exercises will best prevent BMD loss. The stress will be calculated at skeletal locations of most concern during long-duration space flight.

Bone loss is a critical health problem of astronauts in long-term space missions. A growing number of evidence has pointed out bone fluid flow as a critical regulator in mechanotransductive signaling and bone adaptation. Intramedullary pressure (ImP) is a key mediator for bone fluid flow initiation and it influences the osteogenic signals within the skeleton. The potential ImP-induced bone fluid flow then triggers bone adaptation [1]. Previous in vivo study has demonstrated that ImP induced by oscillatory electrical stimulations can effectively mitigate disuse osteopenia in a frequency-depende

Abstract:
The microgravity environment encountered during spaceflight has numerous deleterious effects on the human body, with one of the most drastic being decreased bone mass due to mechanical unloading. These alterations in bone mass and skeletal strength are one of the foremost limitations of future space exploration. Due to the cost of long-duration space missions, it is critically important to develop ground-based models of the microgravity environment encountered during spaceflight to investigate possible countermeasures to maintain skeletal integrity.
