thermal contact conductance (tcc) between an exhaust valve and its seat is one of the important parameters to be estimated in an internal combustion engine. an experimental study presented here to acquire temperature in some interior points to be used as inputs to an inverse analysis. an actual exhaust valve and its seat are utilized in a designed and constructed setup. conjugate gradient metho...

Th17 cells are a new T-cell subtype characterized by the capability of producing IL-17. They are reported to be involved in a wide range of cutaneous immune-mediated conditions and, particularly in this review, we sought to elucidate the Th17 role in the pathogenesis of some common inflammatory diseases including psoriasis, allergic contact dermatitis and atopic dermatitis.

this study was conducted to examine if allergic contact dermatitis (acd) alters the expression of mmps in human dermal fibroblasts. fibroblasts are the primary source for mmp and matrix production in skin. mmps are known to involve in a number of physiological and pathological processes. some published data indicated a gelatinase-like activity in acute and chronic phases of allergic contact der...

Background: Multiple myeloma (MM) is a malignant plasma cell proliferative disorder with limited immunotherapy treatment because of T cell dysfunction. Objective: To investigate the immunomodulatory function of bone marrow mesenchymal stromal cells (MM-BMSCs) on CD8+ T cells. Methods: Proliferation and cytotoxicity were detected by c...

During pathfinding, growth cones respond to guidance cues by altering their motility. This study shows that motile responses can be highly specific: filopodial contact with two different, physiologically relevant cells differentially alters discrete elements of motility. With each cell type, the responses to contact are invariant. Each cell induces a distinct response in sensory growth cones wi...

Understanding how stem cells interact with cardiomyocytes is crucial for cell-based therapies to restore the cardiomyocyte loss that occurs during myocardial infarction and other cardiac diseases. It has been thought that functional myocardial repair and regeneration could be regulated by stem cell-cardiomyocyte contact. However, because various contact modes (junction formation, cell fusion, p...

Dynamic rearrangements of cell-cell adhesion underlie a diverse range of physiological processes, but their precise molecular mechanisms are still obscure. Thus, identification of novel players that are involved in cell-cell adhesion would be important. We isolated a human kelch-related protein, Kelch-like ECT2 interacting protein (KLEIP), which contains the broad-complex, tramtrack, bric-a-bra...
