Cat Poop and Cancer

toxo1

 

Toxoplasmosis.

That’s a big scary word. What it means is an infection with a parasite known as Toxoplasma gondii or T. gondii. And many millions of us are infected. Especially if you are owned by a cat. For the most part such infections are harmless and cause no symptoms or known problems but at times it can cause a flu-like syndrome and rarely severe illness. Here is an article from the CDC on this interesting little critter.

What’s interesting about a T. Gandii infection, or exposure, is that it causes an immune response in humans that is similar to that found in cancer victims. It’s possible that exploiting that immunological reaction could be a useful approach to cancer treatment. Much research lies ahead but it is interesting.

BIO: In the spring of 1973, Mike Tabor embarked on a journey that would take him down a path he could have never imagined. With a freshly earned DDS, Dr. Mike Tabor left Carson-Newman College and The University of Tennessee College of Dentistry, and began his career as a family dentist. In 1983, Dr. Tabor’s work as a family dentist took a unique turn and he found himself immersed in the highly specialized field of forensic dentistry. As one of only a handful of forensic dentists in the United States, Dr. Tabor became a highly sought after expert in this field, performing identifications and examinations on homicide victims, as well as aiding police departments, investigators and medical examiners all over the Country in the prosecution of thousands of crimes.

In September of 2001, Dr. Tabor found himself in New York, at the site of the World Trade Center terror attacks, aiding in the identification of countless victims. For Mike Tabor, this infamous and historical event forever changed his life. As a forensic dentist, Mike was no stranger to the examination of deceased victims, but the horrors of September 11th would not allow Mike, the man, to separate himself from his work as Dr. Tabor, the forensic dentist. September 11, 2011 left a lasting and emotional impression on Mike and gave him a completely new perspective on life and loss.

Dr. Mike Tabor was a featured contributor and has written an entire chapter for the Internationally Accredited Textbook, Forensic Dentistry. He has served as the president of the Tennessee State Board of Dental Examiners, and is currently the Chief Forensic Dentist for The State of Tennessee Office of the Medical Examiner, and is an energetic, engaging and highly respected and sought after public speaker. He makes his home in Nashville, with his beautiful wife, Karen and their two snow white canine children, Mollie and Millie. He is the proud father of two grown children and the doting grandfather of seven adorable grandchildren.

Writers Beware: The Sharks Are Out There

great-white-shark-smile

 

Why is this shark smiling?

Because he’s going to eat your career.

It’s not news to us writers that the world of publishing is undergoing a great upheaval. Some good, some less so. But regardless, it is changing.

And since there is profit in chaos, predators take advantage of this confusion. Maybe it’s an agent that charges reading fees. A publisher who asks writers to pay for book production. A publicist that promises to get you “out there” and then does little. Or perhaps a contract that looks good but in the end gobbles up your hard work like a Great White Shark. And many more scams, often very well disguised.

What’s a writer to do? Like everything else in life, educate yourself so you will know what lies in these treacherous waters. A recent article by Elizabeth S. Craig is a good starting point.

Keep you eyes open and always ask questions. If you don’t like the answers you get, turn the page and walk away. In the long run, you’ll win.

Q and A: How Could My Character Keep Blood In a Liquid State For Later Consumption?

Q: I have a killer who drinks the blood of his victims. If he wants to bleed out a victim and wind up with blood in his freezer that he can reheat in a Mr. Coffee, I assume he’ll need some sort of anticoagulant. Is that right? Would he have to use it immediately at the murder scene? What would the average person have access to that could serve this purpose, especially if he didn’t preplan his first kill. Better still, is there some way to reconstitute the blood after it coagulates?

Craig Faustus Buck, Sherman Oaks CA

 

LEFT: Clotted and Separated Blood RIGHT: Unclotted Blood

LEFT: Clotted and Separated Blood
RIGHT: Unclotted Blood

 

A: Actually there are several ways to accomplish this. If your killer has access to the victim for several days or weeks prior to the event, he could slip some Coumadin into his food daily for two or three weeks prior to the killing. Coumadin, or warfarin, is an oral anticoagulant that works mostly in the liver to prevent blood clotting. It takes a week or so to build up to levels that would keep the blood liquid.

That might be cumbersome for your story, so there is another choice. Heparin. Heparin should be given intravenously but it works immediately as an anticoagulant. Your killer could inject a large dose of heparin right before the killing. This would of course require that he have full control of the victim or at least convince the victim that the injection was harmless. Either way, if he gave 100,000 to 200,000 units of heparin intravenously the victim’s blood would be anti-coagulated within seconds and he could then bleed him and store the blood as a liquid for an extended period of time.

Lastly, as he drained the blood he could put it into a container that contained EDTA. This is what is used in the blood vials when blood is drawn that needs to be anti-coagulated for certain tests. It’s a white powder that is available from pharmaceutical supply houses. Mixing some of this with the blood would prevent it from coagulating so it could be stored as a liquid.

As far a reconstituting it, once blood clots it immediately begins to separate into the reddish clot and the yellowish serum. Vigorous shaking or running it through a blender could remix the blood, resulting in a red liquid that he could then consume.

Guest Blogger: Juan Dillon: Sherlock Holmes: Forensic Science Pioneer

Holmes

 

There are very few characters that have managed to assume a personality as pronounced as that of Sherlock Holmes. Even though he was a fictional character created by Sir Arthur Conan Doyle, Holmes was and still is often given the same respect that one gives to a real person. Apart from infusing life into his characters, Doyle was a visionary as well. He created this amazing character that solved crimes with panache and used methods that would be adopted in the field of law making only decades later. Forensic science was not even in its infancy when Holmes solved all those mysteries. When Doyle wrote Holmes, the situation was such that it required eyewitness accounts and ‘smoking gun’ evidence to convict a murderer. It was very easy for murderers to roam scot free as there was practically no evidence against them.

Holmes used fingerprints, blood stains and chemistry to zero in on his suspects. It was fascinating because these methods were not in prevalence at that time. In many ways he has contributed to the existence of the modern detective. Holmes used blood splatter patterns and bullet trajectory analysis to solve some of his cases. Every forensic detective today has a lot to learn from Holmes when it comes to toxicology. There were many cases where Holmes used scientific methods that involved chemical analysis and even analysis of handwriting. One of the biggest contributions to the world of forensic medicine by Holmes is the ‘exchange principle’ according to which when two things come into contact with each other, one leaves a trace on the other.

The ramifications of the exchange principle were enormous. This means that cases could be solved years or even decades after they were committed. There are instances of how people were exonerated years after they were erroneously imprisoned. There have also been cases of how cases were solved years later and the culprits brought to book. This was possible only through the methods made famous by Holmes. Poisoning was one of the most popular methods of murder in those times and the reason for that was because it was virtually impossible to detect many kinds of poison with the technology available at that time. Holmes would use scientific methods to check the presence of poison in corpses and detect whether a death was indeed natural or unnatural.

In fact there were a few avid readers of Doyle who became so fascinated with the world of forensics that they even set up laboratories for the purpose of research. A Frenchman named Edmond Locard built a forensics lab 23 years after Doyle envisioned a similar one in one of his books. In his lab he kept samples of soil, hair and mineral fibre. This was perhaps the first ever lab that eventually evolved into the state-of-the-art labs that are used by Scotland Yard or FBI. Holmes was also obsessed with something that has now become a science of sorts. He used to analyse shoe prints to solve many of his cases and now that is called Gait analysis. He was also the person who came up with the idea of using dogs to track criminals. He was aware of the ability of a dog’s keen sense of smell way before his contemporaries.

The use of footprints, fingerprints, handwriting etc were a few innovations that can be attributed to Dolye’s intrepid detective. He even did decryption of ciphers, a science that would not be developed even decades after Doyle’s death. It can be said without doubt that Sherlock Holmes, if he was a real human being would have been the world’s first ever forensic scientist. And the credit to that goes to his creator, the visionary called Sir Arthur Conan Doyle.

Can Odor Reveal the Time Of Death?

One of the most important determinations that the medical examiner must make in any death investigation is the Time Of Death (TOD). This alone might help solve a homicide. Who had the motive, means, and opportunity? The time of death relates to the opportunity. If the death occurred while the primary suspect was in another state or had a solid alibi, then he moves down the suspect list. On the other hand, if the TOD was determined to be a time frame where he was in the neighborhood, then he remains a viable suspect.

The ME uses many techniques to help estimate the TOD. Check out this ARTICLE for a brief overview of these techniques. One of the methods he employs is the degree of decay that has occurred. He must take into account the environmental conditions near the corpse and then must make a best estimate as to how fast the decomposition process would have advanced under those conditions. This is always a best guess, as is the case with each of the techniques he employs.

When a corpse decays it undergoes a chemical decomposition and this process releases many volatile organic compounds (VOCs) into the surrounding air. These compounds are at least partially responsible for the odor of decay and they tend to be released in a predictable pattern as the decay process progresses. What if these VOCs could be sampled and used as a more scientific method for determining the Post Mortem Interval (PMI)? That is, the time since death.

Research is currently underway to assess this technique. Using the combination of gas chromatography and mass spectrometry (GC/MS), researchers have found that these volatile chemicals can be trapped and analyzed. Hopefully this technique will prove to be useful in narrowing down the TOD. We’ll see.
