To uphold the quality of
Wikipedia:Good articles, all articles listed as Good articles are being reviewed against the
GA criteria as part of the
GA project quality task force. While all the hard work that has gone into this article is appreciated, unfortunately, as of March 9, 2010, this article fails to satisfy the criteria, as detailed below. For that reason, the article has been delisted from
WP:GA. However, if improvements are made bringing the article up to standards, the article may be nominated at
WP:GAN. If you feel this decision has been made in error, you may seek remediation at
WP:GAR.
The article appears to contain copyright violations such as:
The most common disaccharide unit is composed of a 2-O-sulfated iduronic acid and 6-O-sulfated, N-sulfated glucosamine, IdoA(2S)-GlcNS(6S) from {
http://www.medic8.com/medicines/Panheprin.html}
Under physiological conditions, the ester and amide sulfate groups are deprotonated and attract positively-charged counterions to form a heparin salt. from {
http://www.medic8.com/medicines/Panheprin.html}
The three-dimensional structure of heparin is complicated by the fact that iduronic acid may be present in either of two low-energy conformations when internally positioned within an oligosaccharide from {
http://www.medic8.com/medicines/Calciparine.html}
Heparin is a naturally-occurring anticoagulant produced by basophils and mast cells.[10] Heparin acts as an anticoagulant, preventing the formation of clots and extension of existing clots within the blood. from {
http://www.medic8.com/medicines/Panheprin.html}
Danaparoid, a mixture of heparan sulfate, dermatan sulfate, and chondroitin sulfate, can be used as an anticoagulant in patients that have developed HIT. Because danaparoid does not contain heparin or heparin fragments, cross-reactivity of danaparoid with heparin-induced antibodies is reported as less than 10% from {
http://www.medic8.com/medicines/Panheprin.html}
A serious side-effect of heparin is heparin-induced thrombocytopenia (HIT). HIT is caused by an immunological reaction that makes platelets a target of immunological response, resulting in the degradation of platelets from {
http://www.heparin-law.com/adverse_heparin_reactions.html}
Heparin is one of the oldest drugs currently still in widespread clinical use. Its discovery in 1916 predates the establishment of the Food and Drug Administration of the United States, although it did not enter clinical trials until 1935. from {
http://newjournal.kcsnet.or.kr/main/j_search/j_download.htm?code=B091242}
The enzymes traditionally used to digest heparin or HS are naturally produced by the soil bacterium Pedobacter heparinus (formerly named Flavobacterium heparinum). from {

None of these sites shows a GFDL or Commons type licence. All but boinc.com show copyright notices. As a result of this I am going to immediately de-list this artcile. I have not examined every phrase, but it appears that there is little in the article that is copyuright free.
As commented below by
User:MarcoTolo these in fact appear to be copyright violations in the other direction, so I am happy to cancel that concern.
Prose concerns:
There are a number of single or double sentence paragraphs, please try to organise better. Not done
Heparin dose can be effectively managed using techniques like
Sonoclot As the Sonoclot article does not exist, I am left unclear by this statement, please expand and explain. As a general point, wikilinking alone is not enough when introducing unfamiliar terms. This is a good example of where a brief explanation would be good, even if there was a Sonoclot article. Commensense of course applies, I believe that the general reader aimed at should be familiar with at least high school science. Done this sentence has been removed
For a full discussion of the events surrounding heparin's discovery see Marcum J. (2000), better to say something like: Marcum's paper on "The origin of the dispute over the discovery of heparin" gives a full discussion of heparin's origin. And then of course the cite. Done
Other uses/information:
WP:MOS suggests turning bulleted lists into prose where possible. Not done
Dircet html links such as like Non-weight-based heparin dose adjustment and Weight-based-heparin dose adjustment and 1HPN should be avoided and replaced by prose and cites.
The article is well referenced, but I found a number of dead links, and fixed some others. I tagged the links, but couldn't find archived versions at the Internet Archive, which may be temporarily down.Not done One other citation (#51)
[1] doesn't support the statement.Not done Probably somewhere else on the site.
The copyright concerns listed above are sufficient for immediate de-listing. However I will notify major contributors and projects for a response. On hold for three days.

OK, I am pleased that the copyvio thing was a red herring, although it would appear that in fact this ought to be reported to Wikipedia as we are not properly attributed on many of these sites. The remaining prose and dead links need addressing so on hold for seven days. Hopefully things can be fixed up by then.

After running the Copyright Violation Detector tool (output below; original job run
here) I'm beginning to suspect the copyvio is the other direction (i.e. non-free use of Wikipedia material):

The hanging chemical names (without the corresponding images) on the

boinc.com version of the same page);
The phrase "Heparin is one of the oldest drugs currently still in widespread clinical use. Its discovery in 1916 predates the establishment of the United States Food and Drug Administration, although it did not enter clinical trials until 1935." has been in the Wikipedia version since at least 2008-06-11 (per
this version), while the
Bulletin of the Korean Chemical Sociey paper is listed as having been received 2009-05-31;
The above is also true for
this link dated 2008-10-14;
Refreshingly, the
Wellsphere link actually does cite Wikipedia (go figure);
There are other links I didn't follow, but given the above I suspect we have a whole host of sites (and at least one academic paper!) blatantly ripping-off WP content. --
