background and aims. microleakage is still one of the major problems of composite-based restorations. this study compared the microleakage and thickness of resin cement in ceramic inlays with various temperatures. materials and methods. class v cavities were prepared on the buccal and lingual aspects of thirty human molars with occlusal margins in enamel and gingival margins in dentin (3 mm wid...

Calmodulin (CaM) binds to the skeletal muscle ryanodine receptor Ca(2+) release channel (RyR1) with high affinity, and it may act as a Ca(2+)-sensing subunit of the channel. Apo-CaM increases RyR1 channel activity, but Ca(2+)-CaM is inhibitory. Here we examine the functional effects of CaM oxidation on RyR1 regulation by both apo-CaM and Ca(2+)-CaM, as assessed via determinations of [(3)H]ryano...

BACKGROUND While cam resection is essential to achieve a good clinical result with respect to femoroacetabular impingement (FAI), it is unclear whether it should also be performed in cases of borderline developmental dysplasia of the hip (DDH) with a cam deformity. The aim of this study was to evaluate improvements in range of motion (ROM) in cases of cam-type FAI and borderline DDH after virtu...

Face and hand tracking are important areas of research, related to adaptive human-computer interfaces, and affective computing. In this article we have introduced two new methods for boundary detection of the human face in video sequences: (1) edge density thresholding, and (2) fuzzy edge density. We have analyzed these algorithms based on two main factors: convergence speed and stability again...

. Traditional camera pedestals are manually operated. Our long term goal is to construct a fully autonomous pedestal system which can respond to changes in a scene and mimicking the human camera operator. In this paper, we discuss our experiments to control the vertical motion of a pedestal by leveling its position with a human head or a tracked hand-held object. We describe a set of computer v...

background: contralateral axillary metastasis (cam) is a rare entity in patients with breast cancer which can occur during the primary breast cancer or its follow-up. different treatment modalities include surgery, radiotherapy, and chemotherapy, but there is no agreement on them. in our review, we found 12 series with available data, 82 patients with synchronous or metachronous contralateral a...

The activation of Ca2+/calmodulin (CaM)-dependent protein kinase II (CaM-KII) by Ca2+/CaM results in autophosphorylation and the generation of Ca2+/CaM-independent enzyme activity. We postulated that CaM binding and subsequent autophosphorylation alters the conformation of CaM-KII and exposes its substrate-binding and catalytic site(s). Previous peptide mapping studies on CaM-KII demonstrated t...

The potential relationship of cell adhesion to embryonic induction during feather formation was examined by immunohistochemical analysis of the spatiotemporal distribution of three cell-adhesion molecules (CAMs), neural CAM (N-CAM), liver CAM (L-CAM), and neuron-glia CAM (Ng-CAM), and of substrate molecules (laminin and fibronectin) in embryonic chicken skin. The N-CAM found at sites of embryon...

AIMS To examine policies and practices relating to the provision, prescription and monitoring of complementary and alternative medicine and therapies (CAM) in conventional cancer services in NSW. METHODS Self-administered questionnaire sent to directors of all 65 eligible cancer services in NSW in 2009. RESULTS Forty-three services responded to the survey (response rate 66%). Only six (14%)...
