Spongiosis. Spongiosis is mainly intercellular [1] edema (abnormal accumulation of fluid) in the epidermis, [2] and is characteristic of eczematous dermatitis, manifested clinically by intraepidermal vesicles (fluid-containing spaces), "juicy" papules, and/or lichenification. [3] It is a severe case of eczema that affects the epidermis, dermis ...

Psoriasis is a long-lasting, noncontagious autoimmune disease characterized by patches of abnormal skin. These areas are red, pink, or purple, dry, itchy, and scaly. Psoriasis varies in severity from small localized patches to complete body coverage. Injury to the skin can trigger psoriatic skin changes at that spot, which is known as the Koebner phenomenon.
Fibonacci sequence. A tiling with squares whose side lengths are successive Fibonacci numbers: 1, 1, 2, 3, 5, 8, 13 and 21. In mathematics, the Fibonacci sequence is a sequence in which each number is the sum of the two preceding ones. Numbers that are part of the Fibonacci sequence are known as Fibonacci numbers, commonly denoted Fn .

In addition to MEDLINE, PubMed provides access to: 1. older references from the print version of Index Medicus, back to 1951 and earlier 2. references to some journals before they were indexed in Index Medicus and MEDLINE, for instance Science, BMJ, and Annals of Surgery 3. very recent entries to records for an article before it is indexed with Med...
Website design
A new PubMed interface was launched in October 2009 and encouraged the use of such quick, Google-like search formulations; they have also been described as 'telegram' searches.By default the results are sorted by Most Recent, but this can be changed to Best Match, Publication Date, First Author, Last Author, Journal, or Title. The PubMed website design and domain was updated in January 2020 and became default on 15 May 2020, with the updated and new features.There was a critical reaction from...
Journal article parameters
When a journal article is indexed, numerous article parameters are extracted and stored as structured information. Such parameters are: Article Type (MeSH terms, e.g., "Clinical Trial"), Secondary identifiers, (MeSH terms), Language, Country of the Journal or publication history (e-publication date, print journal publication date).

A reference which is judged particularly relevant can be marked and "related articles" can be identified. If relevant, several studies can be selected and related articles to all of them can be generated (on PubMed or any of the other NCBI Entrez databases) using the 'Find related data' option. The related articles are then listed in order of "relatedness". To create these lists of related articles, PubMed compares words from the title and abstract of each citation, as well as the MeSH headin...
The National Library of Medicine leases the MEDLINE information to a number of private vendors such as Embase, Ovid, Dialog, EBSCO, Knowledge Finder and many other commercial, non-commercial, and academic providers. As of October 2008[update], more than 500 licenses had been issued, more than 200 of them to providers outside the United States. As l...
Alternative methods to mine the data in PubMed use programming environments such as Matlab, Python or R. In these cases, queries of PubMed are written as lines of code and passed to PubMed and the response is then processed directly in the programming environment. Code can be automated to systematically query with different keywords such as disease...
t. e. Lithography (from Ancient Greek λίθος, lithos 'stone', and γράφω, graphō 'to write') [1] is a planographic method of printing originally based on the immiscibility of oil and water. [2] The printing is from a stone ( lithographic limestone) or a metal plate with a smooth surface. It was invented in 1796 by the German author and ...
This image shows how two transparent cels, each with a different character drawn on them, and an opaque background are photographed together to form the composite image. The cel animation process was invented by Earl Hurd and John Bray in 1915. The cel is an important innovation to traditional animation, as it allows some parts of each frame to be repeated from frame to frame, thus saving labor.
