Dom

(dōm), peak, 14,942 ft (4,554 m) high, Valais canton, S Switzerland, in the Mischabelhörner group. It is the highest peak entirely in Switzerland.

DOM

(1) See disk on module.

(2) (Document Object Model) A programming interface (API) from the W3C that lets applications and scripts access the content of HTML, XML and XHTML files in a hierarchical tree structure. The DOM was introduced in 1998.

A Web Page Looks Like a Tree
The DOM implementation lays out the tags in the Web page as a hierarchical tree. In 2000, Level 2 (DOM2) gave the programmer a standard way to handle events associated with elements such as mouse down, mouse click and mouse over. Events may be preprocessed at any tag location from the top of the tree to the target tag at the bottom ("capture" phase) and then back up ("bubbling" phase). These phases were implemented to be backward compatible with earlier Netscape and IE browsers.

XML Data Looks Like a Database
The DOM converts XML documents into a hierarchical node tree in memory that looks like a database record. The node tree allows updating in a similar manner to database updating, making data exchange between XML documents and databases more straightforward. Without DOM turning the document into an object model and handling the updating, the text and tags in an XML document would have to be scanned sequentially and rearranged by the program. See DOM implementation, DOM application, SAX and object model.


Nodes in an XML Record
DOM converts (parses) an XML document into a hierarchical node tree. Writing an XML update program is then similar to writing a database update program, using the same kinds of functions available in a database management system (DBMS).

In about half the cell lines tested, they noted that ATF2's control over MITF is indirect - ATF2 actually controls a protein, called SOX10, which is in turn necessary for MITF expression.
56) SOX10, a panschwannian and melanocytic marker, may also show positivity in myoepithelial cell tumors (Figure 8, A through C).
Additional immunohistochemical markers were applied and revealed tumor cell positivity for SOX10, Mart-1, and HMB-45.
The noteworthy or emerging markers mentioned in this review include S100, mammaglobin, vimentin, EMA, and balanced translocation t(12;15)(p13;q25) for mammary-analog secretory carcinoma; microphthalmia-associated transcription factor (MITF) and SOX10 for mucosal melanoma; diffusely positive p40 and p63 for basaloid squamous cell carcinoma; p63, Epstein-Barr virus-encoded small RNA (EBER), and latent membrane protein 1 (LMP-1) for nasopharyngeal carcinoma; loss of parafibromin, galectin3 overexpression, increased Ki-67 index, and expression of protein gene product 9.
Positive staining for SOX10 and DOG1 reliably distinguished AciCC on FNA cell blocks from its most-common benign mimickers, WT and oncocytoma.
16) Granular cell tumors, unlike ASPS, lack the fine intercellular vascularity and are positive for S100, SOX10, inhibin, and nestin.
57) EWSR1 rearrangements in AFH have not been shown to cause the downstream activation of the MiTF pathway and melanogenesis seen in CCS, (23,36,37) and MiTFM and SOX10 expressed in CCS with EWSR1-ATF1 are not detectable in AFH with this fusion.
1-4) The SOX10 nuclear protein has been shown to be widely expressed in normal human tissues, including melanocytes, Schwann cells, breast and salivary gland myoepithelial cells, and oligodendroglial cells.
104) SOX10 has proven to be as sensitive a marker for DM as S100 with improved specificity (Figure 3, D).
12) SOX10 is a more sensitive and specific marker for melanocytic and schwannian tumors than S100.
Finally, lineage-specific markers, which tend to show nuclear staining, include ERG as a marker of endothelial differentiation and SOX10 as a marker of neuroectodermal differentiation.
