PostGenomic Science Blog Aggregator

For those who enjoyed our podcast on science blogs, here is a newly discovered resource to help make it easier to follow the science blogosphere -- PostGenomic.

PostGenomic is an aggregator -- a source that compiles or aggregates information from a variety of sources. In this case, PostGenomic collects information from a variety of science blogs, and repackages in a way to make them more useful. It has several very nice features, including (my favorite) the option to track your favorite blog postings and see who is talking about them. It collects science blogs across domains, so is broad in scope, but I have yet to visit their main page without finding something of interest. A marvelous resource!

Today's News: Birth Defect Discoveries

Both Harvard and University of Iowa were in the news today for discoveries related to the genomics of birth defects.

Researchers at Harvard's Joslin Diabetes Center identified a compound (Glut2) that contributes to the increased incidence of babies born with birth defects among diabetic women.

The Harvard Crimson: Researchers Find Protein To Be Harmful to Babies of Diabetics, By Michal Labik: http://www.thecrimson.com/article.aspx?ref=517654

At the University of Iowa, Briget Riley was the primary author of a recent study in PNAS describing seven new genetic mutations associated with clefting.

Head's Up: Glucosamine links Atherosclerosis, Diabetes, Arthritis

Glucosamine is a popular over the counter treatment to allieve joint pain in arthritis. Glucosamine has also been receiving increasing attention in the research literature as a potential cause of diabetes. It is also linked to atherosclerosis. Glucosamine has been proposed as an ingredient in a 'vitamin cocktail' for treating Ehlers-Dahlos patients. Might it be possible that this could be another factor connecting this cluster of systemic diseases often associated with periodontitis?

Here is a recent article from UM researchers on this topic, stating that for now it is considered safe for diabetics to use glucosamine.

Stumpf JL (jlstumpf@umich.edu), Lin SW.
Effect of glucosamine on glucose control.
Ann Pharmacother. 2006 Apr;40(4):694-8. Epub 2006 Mar 28.
PMID: 16569816 [Requires UM login]

"Small, short-term studies suggest that glucosamine may be used in selected patients without affecting glucose control; however, data in patients with diabetes mellitus are limited, and close monitoring for potential changes in glucose control is recommended."

Here are just a couple examples of the literature debating this relatively new topic.

Robertson LA, Kim AJ, Werstuck GH.
Mechanisms linking diabetes mellitus to the development of atherosclerosis: a role for endoplasmic reticulum stress and glycogen synthase kinase-3.
Can J Physiol Pharmacol. 2006 Jan;84(1):39-48.
PMID: 16845889 [Requires UM Login]

"We hypothesize that the accumulation of intracellular glucosamine observed in conditions of chronic hyperglycaemia may promote atherogenesis via a mechanism involving dysregulated protein folding, activation of endoplasmic reticulum (ER) stress, and increased glycogen synthase kinase (GSK)-3 activity."

Buse MG. Hexosamines, insulin resistance, and the complications of diabetes: current status.
Am J Physiol Endocrinol Metab. 2006 Jan;290(1):E1-E8. Review.
PMID: 16339923 [Free]

"There are numerous papers showing a correlation between increased flux through HBP and insulin resistance; however, the causal relationship has not been established. More recent experiments in mice overexpressing GFAT in muscle and adipose tissue or exclusively in fat cells suggest that the latter develop in vivo insulin resistance via cross talk between fat cells and muscle. Although the relationship between HBP and insulin resistance may be quite complex, it clearly deserves further study in concert with its role in the complications of diabetes."

Neanderthal's Molars, Future Genius, Scientific Fraud, & Diagnosis in Diversity: Article Highlights from Science Journals

Interesting articles selected from new issues of Nature and Science. NOTE: You must be a UM patron to have access to these. If you are a UM patron and have trouble accessing the articles linked below, try using on on-campus computer, or accessing the articles from the Electronic Journals page.

Scientific American: Oral and Whole Body Health:

"It's a first step on the journey as we work together to uncover the most important and factual information there is regarding the important role good oral health can play in achieving whole body wellness."

How Neanderthal molar teeth grew
Roberto Macchiarelli et al.
Abstract: http://www.nature.com/nature/journal/v444/n7120/abs/nature05314.html

"Here we show that the timing of molar crown and root completion in Neanderthals matches those known for modern humans but that a more complex enamel–dentine junction morphology and a late peak in root extension rate sets them apart."

Futures: Awakening the genius within, Revolution in the head.
Daniel Gregory

"Teetering on the knife-edge, the humans struggled against the Inspiron and the talent that it could give them."

The right tools can save lives
Effective diagnosis, paired with treatment, for developing-world
diseases can have far-reaching impacts, says the Global Health
Diagnostics Forum.

"The Forum has defined the need and impact of diagnostics for six devastating disease groups. Now we challenge scientists, technology developers, funding agencies, policy-makers, international governmental and aid organizations, investors and diagnostic companies to work together to take this forward. A coordinated approach is needed so that appropriate diagnostics can achieve the promised impact."

Donald Kennedy
Responding to Fraud
Science 1 December 2006

"The committee was asked to make a thorough and unsparing analysis of Science's handling of both papers and to make recommendations for changes in procedure that might protect both the journal and the scientific community from further unfortunate outcomes of this kind.

The report, and a short response from Science, are available at www.sciencemag.org/cgi/content/full/314/5804/1353/DC1."

SlideShare.net: Ready, Set, Present!

Dr. X. Pertise agreed to speak to a university group at a meeting that is coming up in two days, on a broad topic peripherally related to his own research, but for which he doesn't have appropriate slides. Dr. P. thought there would be plenty of time to just put together something quick, but something unexpected has gone haywire in the lab at the last minute. He doesn't have time to make presentation slides, so he logs onto SlideShare and looks to see if there is a presentation by anyone he knows on this topic, that he could repurpose for this talk, with appropriate attribution to the original author. A few quick keyword searches, and he has found one presentation that has some good images, another presentation with a good conceptual outline, and some recommended resources that he can easily enrich. He knows the authors, so he contacts them to request a copy of their slides. In the meantime, he sends the links to his assistant, and asks them to start assembling new presentation slides that incorporate these bits. Later, he will quickly reorganize the information the way he wants it for the presentation.


Does this sound too good to be true? Pie-in-the-sky futuring? Well, tah-dah! The future has arrived. SlideShare.net allows people to share their slide presentations. It does not allow people to download the slides, only view them online, but that still can be very useful when assembling ideas in a time-dependent situation. SlideShare is a new service, so the content is still very much growing. Some of the best content is from organizations and government institutions that provide free information as advocates for a specific topic.

Still, you might be surprised what you can find. Examples include presentations on HIPAA and e-mail, four-handed dentistry, medical ethics, professionalism and education, bioinformatics, genomics, the semantic web, craniofacial anomalies, tissue engineering, drug development, and more.

The search interface is particularly sloppy, so you have to do a fair amount of digging once you get to the results. The more specific language is more useful in this circumstance. Like any of the Web 2.0 tools, the quality of what is findable will depend on people who are willing to share their content. If this would be a useful resource to have in the future, consider if it is worth sharing something of yours to make it more useful now.

Genetic and Genomic Information from NLM and the Genetics Home Reference (GHR) (Omics Series, 9)

The United States government, in general, and the National Library of Medicine, in particular, have taken leading roles in providing information, tools, resources, and training for biomedical and life sciences researchers and clinicians, including omics researchers. Very few people make use of the full range of resources they provide. Today, we will survey a few of the broad omics resources available, and then spend a little more time on a specific resource that tends to have information for both dental researchers and clinicians.

This is probably a good time to again mention the forthcoming short course on campus about NCBI resources.

National Center for Biotechnology Information: Short Course, September 7,2006 (Hosted by the Program in Bioinformatics, Department of Human Genetics & Taubman Medical Library): http://www.hg.med.umich.edu/ncbi/

In this course, you will see overviews and demonstrations of how to use many of the databases listed below. NLM and NCBI provide an astonishing number of databases. From their main databases page, you can browse a list of many of their offerings in this area.

NLM: NCBI: Entrez: All Databases: http://www.ncbi.nlm.nih.gov/gquery/gquery.fcgi?itool=toolbar

Here are a few of the specific databases, just to give you an idea of what you might find.

3D Domains: domains from Entrez Structure: http://www.ncbi.nlm.nih.gov/entrez/query.fcgi?db=Domains

Another source they provide is the Human Genome. This resource contains an entirely different list of great tools and resources. I encourage you to explore the Human Genome more on your own.

Human Genome (an integrated, one-stop, genomic information infrastructure for biomedical researchers): http://www.ncbi.nlm.nih.gov/genome/guide/

Last, for today, but not least, is the Genetics Home Reference (GHR). The GHR serves as a bridge between the technical information for researchers and the consumer or general public. It includes information on the correspondence between specific genes and diseases, diagnostic signs/symptoms, an much more. Although the information is for consumers, it can still be fairly technical. It includes a handbook and glossary, which helps, and provides information at a level that can also be useful for the clinician. In addition, they include a list of resources about genetic conditions specifically for clinicians.

NLM: Genetics Home Reference: http://ghr.nlm.nih.gov/

GHR: Genetics Resources for Clinicians and Health Professionals: http://ghr.nlm.nih.gov/ghr/resource/clinicians

Among their newest topics on conditions, you'll find Dentinogenesis Imperfecta and Amelogenesis Imperfecta. Among their new pages on specific genes, you'll find amelogenin (amelogenesis imperfecta 1, X-linked), dentin sialophosphoprotein (DSPP), enamelin, and matrix metallopeptidase 20 (MMP20 or enamelysin). They have also recently added information on a number of specific genes that are associated with the Charcot Marie Tooth Disease. Here is a sampling of pages on dental-related conditions and genes.

Periodontitis or Biofilms as a Source of Disease?

As a break from the Omics blog series, I'd like to just mention an interesting article recently released from the CDC.

O'Connor SM, Taylor CE, Hughes JM. Emerging infectious determinants of chronic diseases. Emerg Infect Dis 2006 Jul. http://www.cdc.gov/ncidod/EID/vol12no07/06-0037.htm

To my mind, this sounded like it really ought to mention some of the recent research in dentistry linking periodontal infections and heart disease. This article doesn't do that, but it does mention biofilms as being related to this line of research. More generally, it is a very interesting overview of research in many different areas of medicine linking various infectious agents with chronic diseases, including cancer. Worth a look.

Introducing our Omics Blog Series

This time of year, new graduate students are flooding into the School and faculty are intensely working on their research projects while the teaching course load is somewhat lighter than during September through May.

While there are a variety of research areas and interests, the University of Michigan and the School of Dentistry have a committed interest in the research areas that have come to be known popularly as "Omics" (genomics, proteomics, nanotechnology, and related bioinformatics concepts).

In the interests of providing useful information for those working in these areas and those who would like to know more about what their colleagues might be doing, the Dentistry Library today begins a roughly two week series of blog entries on OMICS.

The entire collection of entries will be collected at this location, with more added periodically in the future:

What's Hot from the IADR (Our 100th Blog Entry)

As things wind down from the IADR meeting in Brisbane, what are the hot topics that were presented at IADR and receiving attention in the popular press? Cranberries and dentin. That's two ideas, not one.

* Cranberries

Cranberries are receiving renewed attention as a way to prevent caries. The mechanism is similar to the way cranberry juice is known to prevent and cure urinary tract infections -- preventing the bacteria from adhering to the cell surfaces. For dentistry, the idea is that cranberry juice helps to prevent S. mutans from adhering to the teeth, and thus prevents the build up of plaque.

IADR: Berry Good News for Tooth Decay Prevention, by Neil Osterweil:

Koo, Hyun et al. "Cranberry flavonoids on expression of virulence by S. mutans." IADR Abstract 179, presented June 28, 2006 (Brisbane).

* Dentin

Dentin is making news with the popular concept that people can grow new bone. In this case, not only new bone in general, but specifically new dentin. "The data demonstrated that AC-100 stimulated the formation of new dentin (the hard tissue of teeth that protects the tooth pulp and supports the outer enamel) when applied to tooth defects."

Acologix' AC-100 (Dentonin(R)) Phase II Data on Dentin Formation in Humans Presented at the Annual Meeting of the International Association for Dental Research: http://biz.yahoo.com/prnews/060629/sfth064.html?.v=56

Lazarov, Mirella et al. "AC-100, Novel Biological Approach to Promoting Dentin Formations in Humans." IADR Abstract 545, presented June 29, 2006 (Brisbane).

Lazarov, Mirella et al. "AC-100, A Novel Biological Agent for Dentin and Bone Regeneration." IADR Abstract 268, presented June 28, 2006 (Brisbane).

New in PubMed: Related Articles Enhanced

Are you one of the many people using PubMed as your preferred source for Medline searching? Patrons who choose PubMed over OVID for MEDLINE access have told me there are two favorite features of PubMed that contribute to this choice. One is the "Single Citation Matcher" and the other is the "Related Articles" option. Well, the "Related Articles" option has just been improved.

Previously, you would do a search, and then select an article you wanted to look at, such as this one by Laurie McCauley.

McCauley LK, Tozum TF, Kozloff KM, Koh-Paige AJ, Chen C, Demashkieh M, Cronovich H, Richard V, Keller ET, Rosol TJ, Goldstein SA.
Transgenic models of metabolic bone disease: impact of estrogen receptor deficiency on skeletal metabolism.
Connect Tissue Res. 2003;44 Suppl 1:250-63.
PMID: 12952206

In the listing of articles, beside the author names, you would see the words "Related Articles, Links" as active links. If you clicked on "Related Articles", you would then receive a new list of articles that begins with the article you selected. This list is usually very long. For example, today, using the McCauley article above as the jumping-off point, there are 646 related articles.

So, what has changed? Let's say you don't want 646 related articles, at least not to start with. You have an article of interest, perhaps you might think of it as a target article. From the list, you would normally click on the authors for the target article, and this will put you in to the Abstract Display (including citation, PMID, contact information and abstract). Above the article citation, is a menu with a variety of options to customize your display. There is a new option in the "Display" menu -- "AbstractPlus". With this choice, the display gives you a blend of the "Abstract" display and the "Related Articles" -- you will see the top 5 related articles displayed beside the abstract.

A Return to the Focal Infection Theory? Dentistry and Systemic Diseases

While preparing our forthcoming exhibit on the history of dentistry in Michigan, I stumbled across a clever little rhyme that was presented in the entertainment column of the MDA Journal.

There was a little man and he had a little fang
And a billion or so of strepto bugs were in it.
A dentist of renown said I'll put thereon a crown,
For I need all the money there is in it.
Thereupon he made a start; The bugs traveled to the heart,
Of the little man, I really hate to sing it,
For soon there was no little fang, There was no little man,
The tale's too sad, I can't go on, Oh why did I begin it?
Buzzer, A. [pseud.?] "Saydiograms." Michigan State Dental Society Bulletin (June 1924) 6:28.

With that in mind, I thought it would be interesting to highlight a few of this year's articles on the relationship between periodontal disease and various systemic diseases, a recently resurfacing concept very similar to the earlier discredited focal infection theory which, in its heyday, gave rise to the rhyme above.

Each of the articles below was published this year, and either describes a systemic disease as a complication of periodontal diseases or describes periodontal disease as a risk factor for the systemic disease. The Shetty article proposes a mechanism for this -- that the periodontal infection may contribute to immunosuppression.

Clinical Researchers In the News

I've been having trouble with the mBlog software killing off my entries during editing, so please pardon me if there are several sent at once while I try to catch up.

I'd like to bring to your attention the following report of the AAMC in which they call for schools to specifically work to create the next generation of clinical researchers in their educational process.

Promoting Translational and Clinical Science: The Critical Role of Medical Schools and Teaching Hospitals (Report of the AAMC's Task Force II on Clinical Research) May 2006 [62 Pages, PDF 1 MB]: https://services.aamc.org/Publications/index.cfm?fuseaction=Product.displayForm&prd_id=150&prv_id=176

Next, did you see the International Clinical Trials Day? This was last month, so I am sorry to be late bringing this to your attention. A good idea, and I hope it receives broader attention next year. For the record, mark your calendars for May 19th.

European Clinical Research Infrastructures Network (ACRIN): International Clinical Trials' Day: http://www.ecrin.org/ecrin_files/news.php?level=1

Also of potential interest, the American Academy of Microbiology has just issued a new report on "good bugs" -- "how beneficial microbes could represent the future of medicine, with the potential to treat a variety of diseases in humans and animals from diarrhea and eczema to gum disease and autoimmune disorders."

American Academy of Microbiology (AAM) : Critical Issues Colloquia Reports: "Probiotic Microbes: The Scientific Basis," June 2006: http://www.asm.org/Academy/index.asp?bid=43351

Last but far from least for today's entry, the Public Library of Sciences has released a new journal title in collaboration with the AAMC on clinical research.

Online Community Tools: Streamline and Turbocharge Your Information Retrieval

A great deal of the power of science has come from collaborations. These days collaborations increasingly begin online or convert to online when one or the other participants move to another part of the country. Technology is making these connections easier in many ways. here are just a few.

The UM Research site facilitates connections among on campus researchers.

UM Research: http://www.research.umich.edu/

UM Research recommends the Community of Science, saying, "Community of Science publishes databases useful to the research community funding opportunities, in expertise, funded research, patents, and others. UM faculty and staff may search many of these databases free-of-charge." In the Community of Science, you can enter a personal profile describing your research interests, and then subscribe to a notification service for funding announcements in those areas or browse to locate other researchers working in those topics. Very useful.

UM Research: Funding: Community of Science: http://www.research.umich.edu/funding/cos.html

Community of Science: http://www.cos.com/

There are free online comunity resources also. One specifically in dentistry is the Dental Informatics Online Community, which provides "a networking platform for people interested in DI promoting the development of dental information resources, disseminate research results and encourage the formation of research and education partnerships."

Dental Informatics Online Community: http://www.dentalinformatics.com/

Not specifically dental, there are what are becoming known as folksonomy tools -- tools for 'folk' to share information, discover what other 'folk' think is worthwhile, and who the other 'folk' are interested in the same areas as you. Folksonomy tools initially were created for the general public, and over the past few years some have become available specifically for the scientific community. Here is an article about how these are being used in the scientific and research communities.

Social Bookmarking For Scientists - The Best Of Both Worlds, by Ben Lund, Nature Publishing Group, b.lund@nature.com (XTech 2006: "Building Web 2.0" — 16-19 May 2006, Amsterdam, The Netherlands):

So let's take a closer look at how this works in practice, and what you can expect to find. Here is an example of a general purpose folksonomy tool, del.icio.us. Del.icio.us is a "social bookmarking" tool. You can put your bookmarks online, keep them private or share them, and access them from any computer with a network connection. Since del.icio.us is for the general public, its greatest strengths are in finding things of interest to lots of people. Let's see what they have for dentistry or dental.

Del.icio.us: Dental: http://del.icio.us/search/?all=dental

Now, knowing that this is not the likely place to look, let's see what they have for matrix metalloproteinases or MMPs.

Del.icio.us: Metalloproteinases: http://del.icio.us/search/?all=metalloproteinases

Now, let's compare this to what we can find in Connotea for the same topic, knowing that Connotea is for scientists and clinicians, and that it collects citations for articles, not web sites.

Connotea: Metalloproteinases: http://www.connotea.org/search?q=metalloproteinases

Connotea: MMP: http://www.connotea.org/tag/mmp

There are other scientifically focused folksonomy tools, most notably CiteULike. Let's look for MMP articles in CiteULike.

CiteULike: Metalloproteinases: http://www.citeulike.org/search/all?f=title&q=metalloproteinases

Do you like anything you saw? Just checking this topic, it looks like the MMP folk are hanging out at CiteULike, so if I was doing research in that topic, that might be a resource I'd want to start considering.

If you are thinking about using any of these tools, they are especially good to keep your favorite citations handy and accessible whenever and wherever you are. Here is a helpful tool that will allow you to send your favorite references from PubMed to either Connotea or CiteULike from within the Firefox browser. Recommended only for the truly advanced technophile (a.k.a. "geek"). If there is enough interest, I'll try to do a lunch class on this for faculty.

More about Deep Blue

Remember a couple months ago when this blog posted some of the dental faculty publications included in Deep Blue? Well, now you can join those august ranks of faculty whose work will always be remembered. Why will it be remembered? Because more and more faculty are exploring options to archive publications, data, and research images for posterity with the University Library's service Deep Blue. Read on, for a recent press release on this topic.

Deep Blue -- Your work: cited more, safe forever.

The University of Michigan has more than 150 years of experience and expertise in presenting and preserving the world's best research and creativity. With Deep Blue, the UM Institutional Repository, we now have a place specifically for our faculty work. Faculty create it, deposit it online, and decide who should have access. We take care of the rest, for free.

Use it to connect with other scholars: In a cross-disciplinary study, when compared to articles that require paid access, those in systems like Deep Blue "...have consistently more citations, the advantage varying from 25%-250%."[1]

Ask your librarian or send a message to deepblue@umich.edu to get started. For more information about Deep Blue, see http://deepblue.lib.umich.edu/about/

1. Based on a study of 1,307,038 articles published from 1992-2003 in biology, psychology, sociology, health, political science, economics, education, law, business, and management.

JAMA's New Studies on Amalgam's Health Impacts

The prestigious medical journal JAMA released today two randomized controlled clinical trials on the longterm health effects of amalgam restorations in children. Both trials found no measurable ill effects of amalgam.

Neuropsychological and Renal Effects of Dental Amalgam in Children: A Randomized Clinical Trial
David C. Bellinger, PhD, MSc; Felicia Trachtenberg, PhD; Lars Barregard, MD, PhD; Mary Tavares, DMD, MPH; Elsa Cernichiari, MS; David Daniel, PhD; Sonja McKinlay, PhD.
JAMA. 2006;295:1775-1783:
FREE ARTICLE: http://jama.ama-assn.org/cgi/content/full/295/15/1775

"Conclusions In this study, there were no statistically significant differences in adverse neuropsychological or renal effects observed over the 5-year period in children whose caries were restored using dental amalgam or composite materials. Although it is possible that very small IQ effects cannot be ruled out, these findings suggest that the health effects of amalgam restorations in children need not be the basis of treatment decisions when choosing restorative dental materials."

Neurobehavioral Effects of Dental Amalgam in Children: A Randomized Clinical Trial
Timothy A. DeRouen, PhD; Michael D. Martin, DMD, PhD; Brian G. Leroux, PhD; Brenda D. Townes, PhD; James S. Woods, PhD, MPH; Jorge Leitão, MD, MS; Alexandre Castro-Caldas, MD, PhD; Henrique Luis, MS; Mario Bernardo, DMD, PhD; Gail Rosenbaum, MS; Isabel P. Martins, MD, PhD
JAMA. 2006;295:1784-1792.
UM Only: http://jama.ama-assn.org/cgi/content/short/295/15/1784

"Conclusions In this study, children who received dental restorative treatment with amalgam did not, on average, have statistically significant differences in neurobehavioral assessments or in nerve conduction velocity when compared with children who received resin composite materials without amalgam. These findings, combined with the trend of higher treatment need later among those receiving composite, suggest that amalgam should remain a viable dental restorative option for children."

Genetic and Genomic Search Engines

The explosion of genomic and genetic information resources can make it difficult to know what are the best resources for what you need.

The single most famous and comprehensive tool is from the US government.

At Genome.gov, you can find a helpful list describing other recommended genomic and genetic tools.

Molecular Imaging Central includes a useful link section, that includes specialized search engines for genomic information. Sections of the page include "EST and STS Information", "Mapping and Inheritance Information", "Promoter Search and Corresponding Database", "Protein Motifs", and "Sequences Databases".

But new resources are always cropping up. Many are from research institutes, and may include a variety of information in addition to their own discoveries and data. Various international collaborations and journals are represented. Even corporate entities are getting involved, and there is a rumor that Google will be providing the next big genomic database. Here are just a few examples of the range of other resources available.

Zerhouni on "The NIH Investment"

Today, Dr. Zerhouni, NIH Director, is quoted as saying:

"I have made a decision that we are strategically going to educate people. We are launching a strategic ... campaign to educate the American people about the value of the NIH investment over the last 34 years," Zerhouni said. "I am sick and tired of hearing negative messages about NIH, and I am going to take on directly the job of
educating the people about the extraordinary value of the nation's investment."

"The American taxpayer generously invests $96 per person, per year in the NIH for the future health of our country. To give a sense of perspective about our task, I look at the total $29 billion for NIH – nearly half the discretionary funding for all of HHS—and I know I need to make sure that such a large investment is used in a strategic and systematic way to maximize the chances that better treatments and cures are rapidly developed to stem the rising burden of disease, as health care costs consume over $5,500 per person per year and are rising. NIH is currently using this investment for research to attack hundreds of common diseases and an estimated 6,000 rare diseases or conditions that affect approximately 25 million people in the United States -- diseases and disorders that may strike any of us, our parents, our children or our friends. In recent years, we have taken on new challenges such as biodefense."

Genetics and Craniofacial Disorder Resources

Today we're highlighting a few of the very fine online resources available on these topics. The Genetics Home Reference is a masterful resource made available free by the National Library of Medicine.

NLM: Genetics Home Reference: http://ghr.nlm.nih.gov/

Among their newest topics on conditions, you'll find Dentinogenesis Imperfecta and Amelogenesis Imperfecta. Among their new pages on specific genes, you'll find amelogenin (amelogenesis imperfecta 1, X-linked), dentin sialophosphoprotein (DSPP), enamelin, and matrix metallopeptidase 20 (MMP20 or enamelysin).

Highly recommended.

Another recommended resource (classic rather than current) is Jablonski's Multiple Congenital Anomaly/Mental Retardation. The information provided is core diagnositic features and a chromosome summary.

Less technical and a useful resource for patients and seeking core bibliographies on a topic is the website and database for NORD. Print copies of the book are in Reference [RC 48.8 .N3851]. The website has free content and paid content. Persons currently affiliated with the University of Michigan can get both through MIRLYN. The link below goes only to the free content.

National Organization for Rare Disorders, Inc. (NORD): http://www.rarediseases.org/

NORD usually provides links to quality patient information and public websites on the specific disorders. There are a few excellent overview sites, such as FACES: The National Craniofacial Association, Let's Face It, and World Craniofacial Foundation.
