Page (paper)

A page is one side of a leaf of paper. It can be used as a measurement of documenting or recording quantity ("that topic covers twelve pages").

Oxford dictionary describes a page as one or both sides of a sheet of paper in a book, magazine, newspaper, or other collection of bound sheets.

The page in typography

In a book, the side of a leaf one rea is called the recto page and the other side is called the verso page. In a spread, one reads the verso page first and then reads the recto page of the next leaf. In English-language books, the recto page is on the right and the verso page is on the left.

The first page of an English-language book is typically a recto page on the right, and the reader flips the pages from right to left. In right-to-left languages (Arabic, Hebrew, and Persian, plus Chinese and Japanese when written vertically), the first page is typically a recto page on the left and the reader flips the pages from left to right.

The process of placing the various text and graphical elements on the page in a visually organized way is called page layout, and the relative lightness or darkness of the page is referred to as its colour.

Page (surname)

Page is an occupational surname, derived from page (occupation).

Page (computer memory)

A page, memory page, or virtual page is a fixed-length contiguous block of virtual memory, described by a single entry in the page table. It is the smallest unit of data for memory management in a virtual memory operating system.

Virtual memory allows a page that does not currently reside in main memory to be addressed and used. If a program tries to access a location in such a page, an exception called a page fault is generated. The hardware or operating system is notified and loads the required page from the auxiliary store (hard disk) automatically. A program addressing the memory has no knowledge of a page fault or a process following it. Thus a program can address more (virtual) RAM than physically exists in the computer. Virtual memory is a scheme that gives users the illusion of working with a large block of contiguous memory space (perhaps even larger than real memory), when in actuality most of their work is on auxiliary storage (disk). Fixed-size blocks (pages) or variable-size blocks of the job are read into main memory as needed.

Proposed top-level domain

The Domain Name System of the Internet consists of a set of top-level domains which constitute the root domain of the hierarchical name space and database. In the growth of the Internet, it became desirable to expand the set of initially six generic top-level domains in 1984. As a result new top-level domain names have been proposed for implementation by ICANN. Such proposals included a variety of models ranging from adoption of policies for unrestricted gTLDs that could be registered by anyone for any purpose, to chartered gTLDs for specialized uses by specialized organizations. In October 2000, ICANN published a list of proposals for top-level domain strings it had received.

Geographic proposals

MED28

Mediator of RNA polymerase II transcription subunit 28 is an enzyme that in humans is encoded by the MED28 gene. It forms part of the Mediator complex.

Function

Subunit Med28 of the Mediator may function as a scaffolding protein within Mediator by maintaining the stability of a submodule within the head module, and components of this submodule act together in a gene-regulatory programme to suppress smooth muscle cell differentiation. Thus, mammalian Mediator subunit Med28 functions as a repressor of smooth muscle-cell differentiation, which could have implications for disorders associated with abnormalities in smooth muscle cell growth and differentiation, including atherosclerosis, asthma, hypertension, and smooth muscle tumours.

Interactions

MED28 has been shown to interact with Merlin,Grb2 and MED26.

MED29

Mediator of RNA polymerase II transcription subunit 29 is a transcription suppressor that in humans is encoded by the MED29 gene. It represents subunit MED29 of the Mediator complex.

MED29, along with Med11 and MED28 in mammals, is part of the core head-region of the Mediator complex. Med29 is the apparent orthologue of the Drosophila melanogaster Intersex protein (IXL), which interacts directly with, and functions as a transcriptional coactivator for, the DNA-binding transcription factor Doublesex, so it is likely that mammalian Med29 serves as a target for one or more DNA-binding transcriptional activators.
