Several characteristics of receptor capping in lymphocyte membranes suggest similarities with mechanisms underlying control of contraction in smooth muscle fibers. Both capping and contraction are Ca2+ dependent and require metabolic energy. Contractile proteins such as actin and myosin are associated with the cap, as is calmodulin, which mediates the Ca2+ dependence of smooth muscle contractio...

With the number of high-density servers in data centers rapidly increasing, power capping with performance optimization has become a key challenge to gain a high return on investment by accommodating the maximized number of servers allowed by the limited power supply and cooling facilities. Various power capping solutions have been recently proposed for high-density servers and different compon...

The purpose of the present study was to evaluate morphologically the response of feline teeth pulp to direct pulp capping with two different self-etch adhesive systems. Twenty-four cavities in feline teeth were mechanically exposed and assigned to one of two experimental groups: AdheSE + Tetric Ceram (the ASE group), or Adper Prompt L-Pop + Filtek Supreme (the APLP group). There was also a cont...

We offer new insights into the roles played by surface capping in controlling the pattern of growth involving Pd cubic seeds and a HAuCl4 precursor. The final products can take different surface structures (concave vs. flat side faces) depending on the presence or absence of surface capping.

When motile cells are incubated with Forssman glycolipid, the antigen is incorporated into the cells' plasma membranes. If cross-linked by antibody, the patched glycolipids cap. This process is sensitive to those drugs that are known to inhibit capping of protein antigens. The results support a flow mechanism for capping.

background and aims: we aimed to assess the bond strength of composite resin to three pulp capping biomaterials; proroot mineral trioxide aggregate (pmta), root mta (rmta) and calcium enriched mixture (cem), using three bonding systems [a total etch (single bond) and two self-etch systems (protect bond and se bond)]. materials and methods: ninety acrylic moulds containing a 6×2 mm hole were div...

Capping proteins limit actin filament growth, but paradoxically increase actin-based cell motility. This has been attributed to funneling of actin monomers to the filament ends that remain uncapped. Using a reconstituted motility system, Akin and Mullins (2008) now demonstrate that filament capping increases Arp2/3-based nucleation and branching, rather than elevating the rate of filament elong...

Emphasis has shifted from the "doomed" organ concept of an exposed pulp to one of hope and recovery. The era of vital-pulp therapy has been greatly enhanced with the introduction of various pulp capping materials. The aim of this article is to summarize and discuss about the various and newer pulp capping materials used for protection of the dentin-pulp complex.
