Foot Race Groton Trails Commettee
Today there was a foot race through the Groton Town Forrest sponsored in part by the Groton trails committee in which my wife is active. The weather was bright, cool and clear, excellent conditions for such a race. I helped out with food for the runners to eat after the race. It is amazing how many brownies such fit people can eat.

Help others and yourself to a longer life
Clinical Trial – The Progeria Research Foundation, http://www.progeriaresearch.org/ , is soliciting funds to support human clinical trials of a potential drug, which is a farnesyl transferase inhibitor. In mice and human tissue culture these inhibitors have been able to reverse many of the traits of this disease. It is fortunate that few have this lethal disease, less than one hundred children, but the same defect may be a cause of aging in all of us but at a slower rate. Please contribute through their web page.

October Sailing on Casco Bay
My friend Tiny ( WWII veteran of the 10th Mountain
Division) and I took the Windchaser out for an October sail. The weather was warm and initially without wind. We motored under sailed to Eagle Island and then past Jewel Island where a couple of cruising sailboats anchored in the bay while their captain and crew were off hiking the island and on to Portland. After a tour of Portland harbor we headed back only to realize that time was short. The marina launch would stop at 4:30 and we only had two hours to make a two and a half hour trip. Fortunately, the wind came up and we motor sailed north making with mooring with 5 minutes to spare or we still might be out there on the mooring.

Bar Harbor Maine
Last week we journeyed Down East to the Mt. Desert region of Maine to help our cousins close up their vacation home on Beech Hill pond for the winter. During our stay we drove along the rugged coast stopping for an alfresco lunch on the terrace of the Bar Harbor Inn and continuing to Southwest Harbor to view the boats.

Horses are dangerous
A good portion of yesterday evening was spent with a friend in the hospital emergency room. She was putting her two horses out after feeding when one tried to kick the other and connected with her leg. Her husband was on the way to North Carolina and he called asking me to go and check on her as she had just called him. Upon arrival there was a limping redhead with blood all over one leg of her jeans. She could walk but not well. A quick trip to the local emergency room resulted in bandages, a tetanus shot, IV antibiotic, X-rays and stitches. My wife was at a meeting and came to relieve me at the hospital around 11:00 pm and the injured person was home by 1:00 am. After five stitches the healing begins.

How do you know that you are a redneck?
We recently purchased a house near Southern Pines NC for our anual jont to the South for horseback riding in March after skiing in Aspen. This is redneck territory as I met our neightor on her front porch with white legs because she was in the process of her annual leg shaving. It seemed to go rather well. She is a dear sweet person who currently has very smooth legs. The place we purchased is rehab in the most general sense of the term. Although Jeff Foxworthy said that we should find a car buried in the front and didn’t, pretty much everything else including several washer, dryers the odd stove and an number or rum bottles were there. The most interesting find was a decade old bottle of pickled pigs feet. It is a different culture for us Yankees. Hopefully our cold blood will adapt.

HIV tests everyone
http://www.phppo.cdc.gov/dls/ila/hivtraining/ are now pushing rapid testing as it is the most reasonable testing method for developing countries as a large health infrastructure is not required. Such rapid testing makes sense even in certain situations in developed countries. A single visit can give an immediate result although confirmatory testing should also be carried out in a timely manor. No test is perfect. We once proposed to make a rapid confirmatory test but could not get support from an FDA advisory panel who wanted to rely on the expensive and old fashioned western blots. So, it is possible to perform rapid screening and rapid confirmatory tests. The market for confirmatory testing is smaller than that for screening tests so there is not much of a commercial pressure to create such rapid confirmatory tests. At this stage, government support would probably be required. The picture is of the Orasure rapid test for HIV. I consulted on HIV testing at Orasure a number of years ago but not on this specific rapid test. It is gratifying that such HIV rapid tests are now getting the support that they deserve. My groups developed a rapid test using different technology that is currently be used by the millions in Africa. This test was discussed in a previous blog.

The curse of Indian food
A check out of the Windchaser showed it to be in good shape but after a run of the engine to charge the batteries it was away home. The meeting yesterday with such great minds had gone well and hopefully will result in a mutually beneficial future. Regardless, is was pleasant to visit with old friends discussing past adventures and future potentials.

Sailing in Casco Bay
Yesterday my wife, her mother and I enjoyed beautiful blue skies, pleasant temperatures and stiff breezes as the Windchaser bent to the wind. Being Sunday, there were many other sailors on the water enjoying beautiful views while providing them to folks on shore. Our poodle enjoyed the adventure except for extreme healing that made its positioning difficult in the cockpit well. This annoyance was compensated for by snacks along the way. The only difficulty was that the pickup buoy on the mooring became tangled in the pendent. I had dropped my passengers off at the dock and was single handing. Untangling the pickup buoy required leaning over the side during a slow pass and giving it a yank. Thus freed, the rest of the operation went without a hich.

Bone density analysis and a patient’s medical history
The medical community continues to make progress toward a fully digital future. People may no longer have to struggle trying to read a doctor’s handwriting. I recently talked to a company trying to improve the situation by automating much of the data collection, transmission and archiving in this area. The digital future means that there will be fewer transcription errors and critical information will be available to medical personnel in a timely fashion. There is always the issue of confidentiality but such issues are not insurmountable obstacles. This last year I had too many interactions with the medical community due to knee and back injuries. Several times, I was asked to provide a medical history. It improved with each recitation as additional ancient maladies came to mind. I know I should keep a list no matter how depressing. However, hopefully in the not too distant future doctors will not have to rely on my pain and or drug (therapeutic not abused) compromised level of recall. There should be a living document recording my diseases as they occur that would be available to emergency room and other health professionals as required.

Update on Rapid HIV test - Capillus lives

Rapid HIV test used in Africa
A number of years ago I worked in development at Cambridge Biotech, which developed and manufactured a number of state of the art HIV test systems. One of our last products to be introduced was a 5-minute test for HIV that used a disposable slide and electronic battery operated reader. If the sample was positive a latex solution formed clumps as the sample flowed through capillary channels in a plastic slide. The results could be read visually or preferably, by the instrument which eliminated interpretation errors. A science magazine, New Scientist, had an article on the issues of routine HIV testing (July 22 2006 pages 8-9). The article included a picture labeled “testing in Africa needs to be backed by treatment” which is of an African reading one of the slides from our product. It is great that the product is still out there helping people.

The Neanderthal genome is to be sequenced
The extinct Neanderthal are our closest relatives. Some believe that we may be a human – Neanderthal hybrid but mitochondrial DNA from ancient bones found only a very distant relationship. The results suggested and humans and Neanderthals had a common ancestor 500,000 years ago, long before modern humans evolved. The sequencing technique to be used in this new study is very different from that used in the human genome project. That technique sequenced relatively long pieces of DNA but the ancient DNA extracted from fossil bones is too short for such techniques. Scientists from Germany's Max Planck Institute for Evolutionary Anthropology are teaming up with a company in Connecticut to map the genome. The company, 454 Life Sciences Corp. has developed an microwell technique using very small beads that can sequence a number of DNA segments in parallel with little equipment and is much better in sequencing short pieces of DNA than more classical techniques. Only 5% of the DNA is Neanderthal in these samples the remainder being bacterial contamination but as bacterial DNA sequences are so different they can easily be identified and removed from the database. It is hoped that this information will aid us in understanding what makes us human.

Cycling in Groton MA
It was to be a very hot day so cycling to the Main Street Café in the morning seemed like a good way to get in a ride before the temperature rose. The rail trail was close by and provided a level path to downtown Groton. The coffee group was smaller as it was Sunday. After a couple of ice coffees I headed out to Johnson’s for more talk and some cold water. On the way back I visited S and A to talk about furnishing second homes and then stopped by Tiny’s. They just had a new stone wall built next to the barn and are turning it into yet another flower garden. The was home was easy hitting the level rail trail again. After mucking the stall I went shopping as Wednesday is my wife’s birthday. Tomorrow it will be a couple of days of sailing in Maine.

Tuesday evening I attended the above seminar on Longwood Ave. Dr. Giddy described the work being done at a McCord Hospital in Durban South Africa. The current president of the Country does not believe that HIV causes AIDS and has been a problem in developing an effective AIDS program. This is in a country in which some areas have a 50% incidence of HIV infection. It is not that bad everywhere but bad. Things are coming around especially with money from President Bush’s HIV program. The new protease inhibitor drugs work and are available but pricy. One of the major problems is compliance in therapy or getting people to take their drugs and stay on the program. Also, reaching people outside the urban centers especially to enlist them in the program is difficult. Three visits and sophisticated testing is required to select the appropriate therapy and difficult choices must be made with regard to who can be treated effectively and who is too far gone to benefit. Treatment of pregnant HIV positive mothers can be very effective in reducing the mother to child transmission frequency.
I was impressed with the testing capabilities available at the McCord Hospital. They seem to be in close contact with people at Harvard and participating in a number of joint studies.

Sailing Casco Bay Maine with Friends
Over the weekend I enjoyed two great days with friends. One came up with me on Friday and we sailed down the bay out past Baily’s Island and back through Potts Harbor. We grilled stake tips on the stern and talked till midnight. In the morning it was bacon an eggs with English muffins before the others came up to join us. We brought the Windchaser in to the dock for loading without incident. Docking is not my favorite thing. After loading an incredible amount of food and drink we set out for the ocean. Breezes were not good so after passing Eagle Island we sort of drifted out past the Portland light. While drifting two sailing mega yachts went by, motoring as there was no wind. This time of year there are mega yacht races in Boothbay and these boat must have been participating. One of these craft had six spreaders on the main mast. It was tall and thin. While drifting Mark and friend went out in the dingy and took photos of the Windchaser with a professional digital camera that takes 16 megabyte pictures. On Sunday evening Buzz gave me some fantastic pictures of the Windchaser under sail in a light breeze. After picture taking the wind came up and the merry crew sailed back to Freeport past Long and
This is the way it should be.

Single handing on Casco Bay
A blue sky with white fluffy clouds greeted me as I arrived again in South Freeport. Time was spent replacing some of the runners on the main sail so that it would be firmly attached to the mast. Things are running well. The Windchaser and I motored out past Pound-of-tea island into Casco Bay headed toward the Goslings. Being a holiday there was a lot of company. As the wind was brisk only part of the genoa was used but we still laid over on our side. My new camera phone took the picture below and a couple of video clips better depicting the crashing of the waves on the hull. The prospect of rain tomorrow sent me home feeling great about an exciting sail.

First sale on eBay
It worked. As noted a few days ago, my windsurfer Independence was put up for sale on eBay. It was listed for “pick up” only as being 12 ft. long it would have been difficult to ship. Two people bid and one met my price. Within a couple of hours after he won the auction, Jesse appeared in our driveway with his dad to pick up the board. He brought cash. After some instruction as to how to assemble mast and sail we tied it to the top of his car and off they drove into the sunset. I had many good times on that board but as I have another, it wasn’t getting used much and was just collecting dust in the garage. I hope that Jesse will have many enjoyable sails on the Independence at his place on a lake in NH.

Sailing with Tiny on Casco Bay Maine
My 89 year old friend Tiny and I took the Windchaser out for a spin on Casco Bay. In the morning the sky was blue with high clouds signaling the change in the weather to rain. Regardless this intrepid duo raised the main and motored out of the harbor into 20 knot winds from the South. A course by Bustin’s Island allowed a reasonable tack that put the boat over on its side. We passed the Goslings and focused on a return plan as low clouds were building and rain looked more and more probable. We almost made it. As we motored past “Pound of Tea” island a gentle but cool rain started to fall. It didn’t build too far and after a time at the mooring tidying things up we took the dingy “plan B” to shore no worse for the wear. This year I have a dingy rack so “plan B” rests out of the water most of the time avoiding the extensive bottom growth experienced in the past. It is amazing how much stuff can grow on blow molded polyethylene.

Were the Neanderthal our ancestors?
These ancient hominids with brains as large or larger than ours went extinct about 35,000 years ago. Some think that they bred with European Cro-Magnon humans and thus made a contribution to the human race. Recent analysis of ancient DNA from says no. The first Neanderthal DNA to be sequenced was mitochondrial DNA which exists in 100-1000 copies per cell and is only inherited from the mother with no contribution from the father. Because of the high copy number and short length it is the most likely to survive for thousands of years. The mitochondrial DNA sequences suggested that there is no close relationship and that our common ancestor was in the distant past. As there is only one Y chromosome per male cell it is much more difficult to recover from ancient sources. Svante Paabo from the Max Planck institute in Germany used a new technique that is much more tolerant of the degradation found in ancient DNA to sequence 75,000 base pairs from non-mitochondrial nuclear Neanderthal DNA. The specimen was a 45,000 old male from Croatia. Some of the sequences were from the individual’s Y chromosome. The data suggested that Neanderthals and humans had a common ancestor over 315,000 years ago, long before modern humans walked the earth.
A note. The Journal Nature wanted $30 for a one page synopsis of this presentation. I was able to get it for free at the U. Mass. Medical School library but of course had to physically be in the library. This system is outrageous as all paper journals are out of date and don’t have the capabilities of the electronic versions. Tax payers in the U.S. and in this case, Germany, pay for the research, travel and publication costs and then any one who wants to use the information has to pay again. Hopefully, paper journals will die a quick and permanent death and we will not have to pay twice for the electronic versions.

Seminar on Alzheimer’s disease including innovative microscopy and immunotherapy
First, Elan pharmaceuticals is in trials of Beta amyloid immunotherapy ( http://www.elan.com/research_development/Alzheimers/ ) as a way to remove the Alzheimrs related beta amylod from the brain and second, the use of a technique called multiphoton confocal microscopy that allows high magnification viewing of live brain tissue.
From Elan’s web site: Beta amyloid immunotherapy is the treatment of Alzheimer’s disease by inducing or enhancing the body’s own immune response in order to clear beta amyloid from the brain. Active immunization stimulates the body’s own immune system to manufacture anti beta amyloid antibodies that may attach to amyloid and clear it from the brain. This, in turn, appears to reduce the build up of beta amyloid in the brain tissue of patients. Through a monoclonal antibody approach (passive immunization), synthetically engineered antibodies directed at beta amyloid are injected into the bloodstream and are thought to help reverse beta amyloid accumulation.
multiphoton confocal microscopy ( http://www.loci.wisc.edu/multiphoton/mp.html ) can look a light only coming from a slice of tissue. Fluorescent tags are used to make specific tissue glow specific colors. The pictures are similar to those form tissue sections but of living tissue. By placing a window in the head of mice the same cells in the same mouse can be observed from day to day. Thus, changes can be monitored in a single animal providing information that is almost impossible to obtain if the animal has to be sacrificed in order to observe the brain tissue microscopically. This is great stuff.

From Ft. Lauderdale to Rhode Island on a trawler passagemaker
My world has just about stopped swaying back and forth after our wonderful trip from Fort Lauderdale to Rhode Island. It was an exciting experience and will be related in this blog as I get the time. Many thanks to the two gracious owners and our expert captain.
While most of the journey was delightful, we did run aground, loose the wing engine, overheat the generator, require the repair of an open through - hull that could have sunk the boat, become a target for the Navy, suffer attack by thousands of flies off the coast of Delaware, doge container ships in the fog and learn of the murder of an acquaintance.
The picture is of a Selene 47 passagemaker, similar to the one used on this adventure, that steams along at only 8 nautical miles per hour but can cross oceans in substantial comfort.
Chronicle of the great ship Auriga and its perilous journey to the far North
PassageMaker Auriga Chronicle 5/17/06
We shook out the sand at 4:00 am & drove to the airport for a 7:10 am flight under a bright sun and clear blue sky. The flight went well and we easily made the connecting flight in Philadelphia after a long walk from concourse to concourse. Chris’s ear infection seemed to be of little trouble so it was good that he did not take the day and a half long train ride to Ft. Lauderdale. All bags appeared in baggage claim and we speed off into the suburbs of Fort Lauderdale in our new rental car. The boat was at a dock in a residential area. Each small house backed up to a palm lined canal with many such boats both sail and power in tight parallel rows. Dinner was at a Mexican restaurant with tamales and blue agave tequilas. The smoky taste of blue agave tequila imparts a special pleasure to margarita drinking. The night was warm early on but cooled as the dawn approached. However, the boat across the canal periodically discharged water from its cooling system which, through the open porthole, sounded like the Jolly Green Giant urinating. .
Chronicle of the PassageMaker Auriga 5/18/06
Irina made coffee in the morning and we feasted on cookies and zone bars. During the day there was more back and forth to boat and grocery store getting supplies interspaced with various repairs and instillations including a new GPS. The CD player had a frustrating short that we were unable to repair. We spent more time getting supplies, repairing a bilge pump level switch, checking fluids, and purchasing a new personal flotation device (PFD) that inflates automatically upon hitting the water. I have one on my boat and now will have two just in case plans A and B don’t work. Dinner was at an Irish pub with fish and chips and Gunnies.
Chronicle of the PassageMaker Auriga 5/19/06
We drove around town with the laptop on searching for an open WiFi hotspot to download a driver needed to repair a GPS. We found several hot spots but none that would allow us access to the web. Our professional captain, Kevin, arrived by air and proceeded with a through boat inspection revealing some hose clamps that needed to be replaced. We shopped for more supplies and were back at the Irish pub for a dinner of mahi mahi, Chris & Irina returned the rental car while Kevin and I inspected the boat engine room. We needed some spare fluids for transmissions etc but it was too late as we had no car.
Chronicle of the PassageMaker Auriga 5/20/06
The excitement of the departure provided little sleep. We were up at 5:30 to prep for leaving the dock. Coffee and coffee cake were provided for breakfast. We started the engine and received instructions on lines from the Captain. Irina and I let go the lines a little early but with maneuvering we left the very tight dock space and headed out through twisted channels and 4 bridges for the ocean. At a critical juncture, we ran aground but were able to back off without incident and head to the fuel dock for back up oils and fluids. The dock store did not have everything we needed so the dock master took Chris in his own car around town to get the remaining items. We left the dock heading into a strong tidal current on the bow. Kevin planed the tactics well having us take the lines off in the correct order at the correct times. There were many boats, small and gigantic, as it was the weekend. Shortly after entering the open sea, Kevin scheduled a surprise “man overboard” drill with Irina doing well and :Chris and I doing less well, A small leak into the engine room bilge was a concern but we kept going monitoring it every two hours.
Chronicle of the PassageMaker Auriga 5/21/06
As luck would have it, the problem was at the most inaccessible part of the boat behind two large gel batteries. Irina did an excellent job of crawling over the batteries to find the problem, the rest of us being to big to maneuver in the tight space. It seems to me that for effective cruising a couple must be composed of one large person for lifting heaving items and one small for crawling into tight spaces. A cooling water return hose had come off its stern port side through-hull fitting. The fitting had a short vertical connector that kept the open inlet above the waterline so water came in only intermittently keeping us from sinking. However, as the rocking increases when under way so does the amount of seawater entering the boat. Very little water was seen at the dock as the water was not being forced into by boat. The loose hose and fittings were behind two large gel batteries accessible through a small opening in the floor and one in the top of the bench. Ropes were attached to a battery and three of us heaved up a battery with difficulty, especially because it had to be turned 90 degrees during the extraction to clear the opening in the bench. The errant hose was reattached and batteries replaced. Soon the Auriga was underway again cursing out past the mega yachts in Palm Beach harbor.
Chronicle of the PassageMaker Auriga 5/22/06
and I take watches of three hours with six hours off. Our captain does not take a watch as he is always on call. Breakfast was coffee and toasted bagels with cream cheese and strawberry preserves. All the crew is up. An aircraft carrier to the east was on maneuvers and was in view for over two hours. It hailed us to get out of the way although he was over 6 miles away. We decided to comply. Other craft were hailed over the period and several times helicopters buzzed us. Perhaps we were a target in war games.
Kevin started up the Yanmar diesel wing engine, which overheated and was shut down. This smaller engine with its saildrive is our plan B if something happens to the main engine. The weather continues to be excellent.
For dinner Arenia made cheese and cracker appetizers followed by meatballs in Italian tomato gravy with roasted potato chunks on the side and fresh bread. Dissert was cheesecake. This was quite an accomplishment on a rolling boat.
