Bone morphogenetic proteins (BMPs) play pleiotropic roles during development and after birth in many different organisms. BMPs are members of TGF-beta superfamily. There are more than 20 members with three type II receptors and three type I receptors. Genetic approaches using the mouse as a model system revealed many of the functions of BMPs. Particularly, results obtained through loss-of-funct...
This study evaluated the reduction effect of non-point source pollution by applying best management practices (BMPs) to a 1.21 km2 small agricultural watershed using a SWAT (Soil and Water Assessment Tool) model. Two meter QuickBird land use data were prepared for the watershed. The SWAT was calibrated and validated using daily streamflow and monthly water quality (total phosphorus (TP), total ...
[This project aims at providing planners with a grid which would allow a comparison between Best Management Practices (BMPs) in terms of environmental efficiency, economic cost and potential acceptability by farmers. A comparison between different existing or simulated BMPs (Best Management Practices) has been carried out through a cost/effectiveness assessment along with the study of their acc...
During bone formation and fracture healing there is a cross-talk between endothelial cells and osteoblasts. We previously showed that vascular endothelial growth factor A (VEGF-A) might be an important factor in this cross-talk, as osteoblast-like cells produce this angiogenic factor in a differentiation-dependent manner. Moreover, exogenously added VEGF-A enhances osteoblast differentiation. I...
Bone morphogenetic proteins (BMPs) comprise a large group of polypeptides in the transforming growth factor beta superfamily with essential physiological functions in morphogenesis and organogenesis in both vertebrates and invertebrates. At present, the role of BMPs in the reproductive system of any species is poorly understood. Here, we have established the existence of a functional BMP system...
In a previous paper, Liu argued for the importance of establishing a precise theoretical foundation for program debugging from first principles. In this paper, we present a first step towards a theoretical exploration of program debugging algorithms. The starting point of our work is the recent debugging approach based on predicate switching. The idea is to switch the outcome of an instance of ...
Efforts to improve water quality increasingly rely on structural stormwater best management practices (BMPs) to remove pollutants from urban runoff. These structures can unintentionally produce mosquitoes and may play a role in the spread of mosquito-borne diseases. A questionnaire was distributed to over 300 stormwater and mosquito control agencies in the United States to assess the prevalence...
The buccal ganglia of Aplysia contain a central pattern generator (CPG) that mediates rhythmic movements of the buccal apparatus during feeding. Activity in this CPG is believed to be regulated, in part, by extrinsic serotonergic inputs and by an intrinsic and extrinsic system of putative dopaminergic cells. The present study investigated the roles of dopamine (DA) and serotonin (5-HT) in regul...
Vascular endothelial growth factor (VEGF) and bone morphogenetic proteins (BMPs), as key mediators in angiogenesis and osteogenesis, are used in a combined delivery manner as a novel strategy in bone tissue engineering. VEGF has the potential to enhance BMPs induced bone formation. Both gene delivery and material-based delivery systems were incorporated in previous studies to investigate the sy...
