Abstract (sommario):

The proliferation of both teacher-made and professionally prepared games might easily tempt a teacher to conclude that using them to kindle a child's interest in mathematics is an end in itself. And yet the full riches of many games may lie undiscovered until children are challenged to go beyond their interests, to think about their actions, and to elaborate on them. From this perspective, the most valuable games are those that interest children and that have rich variations to encourage their growth.

Abstract (sommario):

Children exposed to systemic glucocorticoids often exhibit growth retardation and after the cessation of therapy catch-up growth occurs in many, but not all patients. The developmental regulation and underlying cellular mechanisms of catch-up growth are not fully understood. To clarify this issue, we established an in vitro model of catch-up growth. Here we present a protocol for the long-term culture (up to 160 days) of fetal (E20) as well as postnatal (P8) rat metatarsal bones which allowed us to characterize ex vivo the phenomenon of catch-up growth without any influence by systemic factors

Abstract (sommario):

We analyzed the thoracic limbs of 24 striped dolphins, Stenella coeruleoalba, by means of X-ray techniques. The body length of the dolphins, the number of postnatal dentine growth layers in the teeth, the degree of ossification of the hyoid bones, and development of the gonads (when available) were correlated with X-rays and used to estimate growth stages and skeletal maturity. Newborn animals showed advanced ossification centers in the humerus and at the proximal end of the radius and ulna. The proximal end of the humerus and the distal end of the radius and ulna ossify later, followed by clo

Abstract (sommario):

Background: The role of nutrient foramen (NF) in nutrition and growth of the bones is evident from term Nutrient itself. The nutrient foramen is opening of nutrient canal on the surface of shaft of the bone which conducts the nutrient artery and the peripheral nerves to bones. Long bones receive most of the interosseous blood supply (70% to 80%) from the nutrient arteries and remaning (20% to 30%) through the periosteal vessels. Nutrient arteries play an important role in nutrition and growth of the bones particularly during early phases of ossification and growth. The present study is of grea

Abstract (sommario):

Klotho mutant (kl/kl) mice exhibit growth retardation after weaning, and previous electron microscopic examination of GH-producing cells in pituitary glands revealed a reduction in GH granules. However, it has not been known whether growth retardation in klotho mutant mice is related to the loss of GH function. We therefore examined whether treatment with GH could rescue the retardation of growth. At the end of 3 weeks of treatment with human GH, the body weight of wild-type (WT) mice was increased. In contrast, body weight was not increased in klotho mutant mice even after the treatment with

Evidence strongly suggests that persistent deficits are closely associated with depressed growth, raising the possibility that a permanent end to U.S. deficits would permanently increase the country’s economic growth. However, with nearly a half-century long, almost unbroken line of deficits it is unlikely that Congress will rise to the occasion and end borrowing on its own.

Abstract Abstract 627 Cytotherapy with mesenchymal stem cells (MSCs) has been shown to promote bone formation, inhibit bone disease and reduce multiple myeloma (MM) growth in myelomatous bone (Yaccoby et al., 2006; Li et al., 2011). At the cellular level, the infused MSCs act as a bystander cells that activate endogenous osteoblasts and suppress osteoclast activity. To shed light on molecular mechanisms associated with the cytotherapeutic effects of MSCs we exploited the SCID-hu model engrafted with the Hg MM line. Hg cells are only maintained by passaging in SCID-hu/SCID-rab mice and produce

Abstract (sommario):

AbstractControlled degradation of hydrogels enables several applications of these materials, including controlled drug and cell release applications and directed growth of neural networks. These applications motivate the need of a simulation framework for modeling controlled degradation in hydrogels. We develop a Dissipative Particle Dynamics (DPD) framework for hydrogel degradation. As a model hydrogel, we prepare a network formed by end-linking tetra-arm polyethylene glycol precursors. We model bond breaking during degradation of this hydrogel as a stochastic process.

Abstract. This work aims at understanding future spatial and temporal distributions of tree species in the Mediterranean region of France under various climates. We focused on two different species (Pinus Halepensis and Quercus Ilex) and compared their growth under the IPCC-B2 climate scenario in order to quantify significant changes between present and future. The influence of environmental factors such as atmospheric CO2 increase and topography on the tree growth has also been quantified. We modeled species growths with the help of a process-based model (MAIDEN), previously calibrated over m

Abstract (sommario):

The clavicle is the first bone to begin the process of ossification and the last one to complete it. Whilst histological studies of the clavicle have been focused mainly on embryonic events, our study focused on post natal clavicle development. The objective of this study was to perform a qualitative description of the clavicle’s epiphyseal growth to further shed light on the postnatal ossification process. Histological studies performed on clavicles obtained from cadavers confirmed medial and lateral extremities as true physes. Unlike the development of other long bones, no secondary ossifica

Osteochondromas are common benign tumors of cartilage and bone. They are usually found as contiguous bone with a cartilage cap at the end of the growth plate of long bones. Similar to structure are extraskeletal osteochondromas. However, unlike typical osteochondromas, extraskeletal osteochondromas are noncontinuous with bone. To our knowledge, all reported extraskeletal osteochondromas have been contained within fascial compartments.

Both specimens lack the skull, but one is otherwise nearly complete and articulated, and the other is more fragmentary. Their small size (~300 mm of wingspan), the lack of fusion of several postcranial bones, the minimal epiphyseal ossification, and the porous appearance of the periosteal surfaces indicate the specimens died at a ve

To that end, this Article proposes a Human Development Bond (HDB) with a variable coupon schedule that both insures issuers against recessions and incentivizes them to encourage investment in human capital when economic growt

Endoglin (ENG) is a coreceptor of the transforming growth factor-β (TGFβ) family signaling complex, which is highly expressed on endothelial cells and plays a key role in angiogenesis. Its extracellular domain can be cleaved and released into the circulation as soluble ENG (sENG). High circulating levels of sENG contribute to the pathogenesis of preeclampsia (PE). Circulating bone morphogenetic protein 9 (BMP9), a vascular quiescence and endothelial-protective factor, binds sENG with high affinity, but how sENG participates in BMP9 signaling complexes is not fully resolved. sENG was thought to

Reorientation of the side chain in the 20-epi configuration resulted in analogues that were extremely potent only against LNCaP (ED50 ≈ 5 × 10−11 m).
