INSIDE THIS ISSUE . . . . . ASP NEWS POETRY WRITING CONTEST

John Spikes

Our contest for poems about photobiology (ASP News, May 1, 1997) attracted only three entries from approximately 1600 members of ASP! On hearing this, one of our lonesome poets (Stuart Marcus), commented that "illuminati do not necessarily contain enthusiastic literati". So, we declared all of the poems winners and present them here.

The first poem is by Terje Christensen (Norwegian Radiation Protection Agency, Osteras, Norway). He comments that the most prominent creatures in Norwegian photobiology are the trolls (not to be confused with the native photo-biologists).

Troll Photosensitivity

Norwegian trolls are full of neuroses.
They scare people at night,
But stay out of the light
To protect themselves from apoptosis.

The next poem by Carol A. Burkhart (St. Johnsville, New York) originally appeared in The Delta Kappa Gamma Bulletin, Spring 1993, Volume 59-3, page 63, and is reprinted by permission of The Delta Kappa Gamma Society International.

The Nurturing Touch of Passive Solar

Patiently the little birds wait.
In the mist of spring's awake.
Perched on flowered limbs so high.
They find true warmth rising in the sky.
Oh, what faith little birds show -
Sunshine brings tranquility they know.

The last poem is by Stuart Marcus (DUSA Pharmaceuticals, Inc., Tarrytown, New York). He points out that his poem is in a "vaguely Shakespearean sonnet form, with considerable license taken in the meter" and that "technical words are rarely amenable to iambic pentameter, hexameter, or even dactylic hexameter".

Photodynamic Therapy (PDT), Naturally!

Build thee more stately porphyrins, O my friends!
Like Tin, BPD, Texaphyrin and MACE:
Like m-thpc, phthalocyanines and other odds and ends.
Photochemists are engaged in such a lovely race!

But what of Photofrin , Tom Dougherty's dearest
scion, The best part of HPD, venerable gemisch?
'Though it's been approved few have, of late, been tryin'
To use it to experiment, to create or to publish.

Now, a small molecule's been gathering acclaim.
It's not hydrophobic and just five carbons long,
Works well given topically, orally, or in vein,
And's metabolized to PpIX, a photosensitizer that's strong!

It's made PDT simple (a shame, "experts" will say),
And may it yet make it popular, praised by 5-ALA!

Some poems about science are published in HMS Beagle, The BioMedNet Magazine (web address ; it can also be accessed via ). One poem relating to photobiology ("The Nature of Color") was published in HMSBeagle, Issue 12. Science-related art work ("Einstein Through a Bee's Eye", Issue 8), cartoons and humor also appear on occasion in the magazine.

1998 ASP MEETING SNOWBIRD UTAH - THE MEMBERS' MEETING

Frank Gasparro, Chair Scientific Program

The program for the 1998 meeting is shaping up very nicely. We have commitments for 23 symposia. By running two minisymposia on Saturday evening and reducing the number of symposia by four we are able to reduce the meeting by a half day - it will end on Wednesday afternoon.

Saturday will be a busy day because, in addition to registration, we have plans for several workshops with two confirmed at this time. One of these, "The Role of Photochemistry and Photobiology in the Undergraduate Curriculum", will be co-chaired by Tom Brennan (Dickinson College, PA), Chris Lambert (Connecticut College, CT) and Kevin O'Shea (Florida International University). Another workshop continues the joint ASP-ESP effort - Janusz Beer and Frank deGruijl will co-chair "UV, Accessory to Melanoma - If so, How?". Early Saturday evening, immediately following a sumptuous reception, there will be a keynote speaker.

Paul Strudler from the NIH will be returning this year with his highly acclaimed workshop, "Navigating the Bay of Funding", on Tuesday evening - at which light snacks and liquid refreshments will be provided.

The full schedule will soon be available at POL web site (http://www.kumc.edu/POL). The meeting information packet with registration, hotel information and abstract forms will be mailed in January. The date for receipt of completed abstract forms is February 24, 1998.

Several additional slots for proffered abstracts have been tentatively included in the meeting program and I hope there is an overwhelming response from members who wish to present the results of their research to their colleagues. As I have said many times, ASP is a membership-driven organization. The annual meeting provides a unique opportunity for members to shape the ASP. The scientific content can depend in large part on submissions by members. Please join us at ASP'98 in Snowbird.

Snowbird itself is a vacation destination with many nearby attractions. In a subsequent issue of the Newsletter there will be a tabulation of other nice vacation spots (many National Parks) that are within easy reach of Snowbird, Utah - why not enjoy a midsummer respite before or after the ASP meeting?

ASP AWARDS REMINDER

Please send nominations for the annual ASP Research, New Investigator, and Photon Awards to Secretariat by early December 1997. Details of the awards were published in ASP News vol. 26 (4), September 1, 1997, page 4.

ANNOUNCEMENTS - ATTENTION: SCHOOLS OFFERING COURSES OR DEGREE PROGRAMS IN PHOTOBIOLOGY AND PHOTOCHEMISTRY

If you have looked at the Education section of Photobiology Online recently (http://www.kumc.edu/POL), you know that it includes under programs of study in photobiology a listing of colleges and universities that offer courses or degree programs in photobiology and photo-chemistry. The listing is several years old now and we would like to update it. If you want your institution to be included, please send me the relevant information. The listings include the name of the school, courses and/or degree programs available, special research opportunities, and the name of a person to contact for further information. We will include both graduate and undergraduate level information. If you are already included in the listing, please take a look to make sure the current information is correct and let me know if you want any changes. This is a useful source of information for future photobiologists and their advisors, so let's try to make the listing as comprehensive as possible. Thanks for your help.

ANNOUNCEMENTS - ASP MEMBERS WIN R&D AWARD

Two ASP members, Lisa A. Kelly and John C. Sutherland, were cited by the September issue of Research & Development Magazine as developers of one of the 100 most significant new technological products of the year. Their R&D award is for the Fluorescence Omnilyzer, which detects individual photons of ultraviolet, visible and near infrared light. Like other single photon detectors, the Omnilyzer records the time-of-arrival for each photon, but, in addition, it also records the wavelength and polarization. The prototype, which was developed for studies of the structure and dynamics of proteins, DNA, and other biomolecules, detects fluorescence excited by flashes of light from the National Synchrotron Light Source, although pulsed laser excitation could also be used. The Omnilyzer was described in a "Work-in-Progress" paper at the 1996 ASP meeting in Atlanta, in a regular paper, at the 1997 ASP meeting in St. Louis, and in the June 1997 issue of Review of Scientific Instruments (vol. 68, pages 2279-2286). The scientists who developed the Omnilyzer were led by John Sutherland, a Senior Biophysicist at Brookhaven National Laboratory and Adjunct Professor of Physiology and Biophysics at the State University of New York at Stony Brook. He received a similar award in 1987 for a fluorescence imaging system of a type that has become widely used in molecular biology and technology. Lisa Kelly was Department of Energy Distinguished Post-doctoral Fellow at Brookhaven National Laboratory. She is presently an Assistant Professor of Chemistry and Biochemistry at the University of Maryland Baltimore County. Congratulations on a most interesting innovation!

ANNOUNCEMENTS - PHOTOBIOLOGICAL CENTENNIAL TO START THE NEW MILLENNIUM

John Spikes

Many stupendous happenings, such as the end of the earth, are being predicted for the year 2000 - the beginning of a new millennium. But, for some of us interested in photosensitized (photodynamic) reactions in the biomedical area, one of the major events of 2000 will be the 100th anniversary of two seminal publications by Dr. med. Oscar Raab and by Prof. Dr. Hermann von Tappenier of the Pharmacological Institute, Ludwig-Maximillans University, Munich. These papers describe the serendipitous discovery of the killing of paramecium cells on illumination in the presence of compounds such as acridine, eosin, quinine, etc. (photosensitizers) and include the prediction that such reactions might be useful in the treatment of disease [1-3]. The von Tappenier paper describing this work was Continued published on January 2, 1900, while Raab's dissertation appeared later in the year. As is well known, reactions of this type are now being used successfully in the photochemotherapy of a number of diseases including cancer, various skin disorders, etc. and for the destruction of viruses and other biocontaminants in blood.

Fred Urbach and I have been discussing what could be done at the International Congress on Photobiology in San Francisco in 2000 to properly celebrate this momentous event in the history of photobiology. We are reminding the officers of ASP and ESP and others who will be involved in the organization of the congress about the event to make sure that it will be appropriately recognized. We are also in the process of trying to find out more about Raab (we have adequate information on von Tappeiner).

We also thought that publishing reminders like this one in ASP News might stimulate more interest in the event. It should be pointed out that, although the formal reports of the discovery of photodynamic action were published in 1900, Raab may have actually first observed the phenomenon 110 years from the time that you are reading this issue of ASP News, i.e., in the winter of 1887. In his published dissertation [1], Raab indicates that he started his promotional work under the direction of von Tappeiner in the winter semester of 1887-1888, and he states (in my translation): "At this time of the year the (sun)light fluctuated greatly and it is to this fact that I am largely beholden for the remarkable results that I found...". So, a few of us photodynamic fanatics are celebrating the centennial now.

SHADE DOES NOT PROTECT FROM UVB

On the basis of the following radio piece Council decided to award Charles Osgood the first American Society for Photobiology/Photobiology Foundation Public Service Award, May 1997. His radio broadcast on UVB, including the following poetry recitation, was broadcast on CBS Radio Network. John Spikes has agreed to include this poem as a fourth winner in his contest. For those who wish to "hear" it, go to web site http://www.cbsradio.com/ osgood/index.html - use the calendar to select 2/3/97 and follow instructions.

I'm Charles Osgood on the CBS RADIO NETWORK. Sitting in a doctor's or dentist's waiting room you find yourself reading articles in magazines you never realized existed. Recently, if you were thumbing through the December issue of the International Journal of Biometeorology you might have run across a study showing that the sun's UVB, the BAD ultraviolet rays that can cause cancer and impair the immune system, can do you serious harm EVEN if you've protected yourself by sitting in the shade. Richard Grant of Purdue University and Gordon Heisler of the US Forest Service say people think if they sit OUT of the sun in the SHADE of a tree or an umbrella they'll be OK. But this is not true, they say. The UVB can go around corners and find you even if you cannot see the sun. A better test, Grant and Heisler say, is how much SKY you can see. It's SKYBURN you have to watch out for.

Shade Does Not Protect From UVB

Some people think they've got it made
If they stay in a piece of shade.
Their working theory seems to be
The sun can't hit what it can't see.
And that if you can't see the sun
No major damage can be done.
But now we're told this isn't true.
If you can see a patch of blue,
Outside the tree or beach umbrella
Then you had better watch it, fella.
That lovely summer sky one sees
Is full of deadly UVBs.
That little piece of shade you're in
Won't be enough to save your skin.
Those rays on days so blue and fine
Don't travel in a true straight line.
They curve, they hook, they twist and bend
And catch up with you in the end.
You get more of them than you think;
Your skin turns hues of red and pink.
And that, the experts say, is why
You should try to shut out the sky.
Out in the forest you should be
Beneath that wooded canopy.
They say the less sky that you see
The less the threat of UVB.
That sun that people seem to love,
We think about as up above,
And while from this we try to hide,
It's coming at us from the side.
For UVBs while quite invisible
Are quite enough to make us misable.
This newest study should alert you
That what you cannot see can hurt you.

CARDIOLOGY, ONCOLOGY AND ENDOSCOPE STERILIZATIONS PATENTS ISSUED

Rare Earth Medical, Inc., W. Yarmouth, MA has been issued three U.S. patents covering disposable fiberoptic medical devices. The company's intellectual property portfolio now includes more than 25 U.S. and foreign patents.

"Phototherapy Apparatus with Integral Stopper Device" patent was issued on July 1, 1997. This invention is useful in controlling and limiting an optically transmissive fiber's penetration into a patient's tissue and thereby reducing the risk of perforation of a body lumen or organ. The invention is particularly useful in placing an ablative laser radiation device into the ventricle of the heart when performing arrhythmia-correcting laser ablative procedures or when revascularizing the heart percutaneously. Applications may include the emerging TMR (transmyocardial revascularization) or PMR (percutaneous myocardial revascularization) market.

The second patent, "Loop Diffuser for Diffusion of Optical Radiation", was issued on May 27, 1997. The Loop Diffuser may allow a physician to provide a larger exposure area for phototherapy and to provide a substantially uniform energy distribution to the intended diseased tissue. By looping diffusing fibers at the distal end of an optical fiber the device can provide more uniform and predictable delivery of laser energy to treat diseased cells, and reduced risk of patient injury caused by unintended hot spots. The Loop Diffuser may be appropriate for phototherapy of the uterus, bladder, or other body cavities.

The "Ultraviolet Sterilization of Instrument Lumen" patent was issued on June 10, 1997. The disposable device operates by delivering a cytotoxic ultraviolet light dose to the inner lumen surface of a reusable instrument to sterilize any biological agents which may be present within the instrument's lumen. Rare Earth Medical, Inc. is a leading developer of minimally invasive fiberoptic systems for photodynamic, photochemical, photothermal and dosimetry detection applications. The company's unique products have potential applications in a number of medical specialties, including oncology, urology, cardiology, electrophysiology, and gynecology. Rare Earth Medical's laser diffusing devices are unique with regards to uniform distribution of laser energy, range of device geometries, power handling capabilities, and flexibility.
