A controversial neurosurgeon in Italy said this week that he and his fellow researchers may be able to conduct the first human head transplant next year.
We suggest they start with their own.
Dr. Sergio Canavero has been compared to Dr. Frankenstein, and called a nut, but that hasn’t stopped him and members of his consortium — from China, South Korea and the U.S. — from severing the spinal cord of the beagle above (just so they could try to reattach it) and doing the same with numerous mice.
If that’s not weird enough, Canavero and team say that before they attempt a head transplant on a live human, they will conduct some experiments on human corpses, and then reanimate them with electricity to test his technique.
We can only assume they will do so in the basement laboratory of a castle, during a thunderstorm.
Canavero is director of the Turin Advanced Neuromodulation Group. He released three papers this week, and the video above, showing how he and his collaborators had successfully reattached the spinal cords of the dog and several mice.
Canavero also claims that researchers led by Xiaoping Ren at Harbin Medical University have already performed a head transplant on a monkey – connecting up the blood supply between the head and the new body.
Canavero’s short term goal is to successfully transplant a human head. His long term goal, he admits, “is immortality.”
What’s an acceptable number of dogs to torture in a quest of that nature?
We’d say none.
Canavero says the experiments on animals prove the technique used — known as GEMINI spinal cord fusion — incorporates a chemical called polyethylene glycol, or PEG, to encourage neurons to grow toward each other and connect.
He suspects it will also work in humans to fuse two ends of a spinal cord together, or to connect a transplanted head to a donor body.
He made the claims in a series of papers published in the journal Surgical Neurology International.
The claims have been met with widespread skepticism, according to New Scientist.
Canavero first announced his plans to conduct a human head transplant in 2013 and established the ead Anastomosis Venture, or HEAVEN, project to develop the techniques needed to carry out such an operation.
His collaborator in South Korea is Dr. C-Yoon Kim, a neurosurgeon at Konkuk University in Seoul who partially severed and reattached the spinal cords of 16 mice. Five of the eight mice who received PEG regained some ability to move. The other three died — as did eight who were in a control group.
In another experiment the South Korean team nearly severed the spinal cord of a dog. While the dog was initially paralyzed, three days later the team reported it was able to move its limbs and wag its tail.
South Korea is also the birthplace of dog cloning and up until this summer — when an American company cloned a dog for a customer — it was the only country cloning dogs for profit.
It’s probably not too outlandish — given all the bizarre turns medical researchers are taking — to wonder if surplus canine clones in South Korea end up being used for other wacky experiments by mad (or at least overly zealous) scientists.
In fact, if you look at its history, creating dogs for medical research use was one markets mentioned by the developers and marketers of dog cloning.
Could it be that some of the ideas initially presented in science fiction might ought to remain in the realm of science fiction?
Canavero’s research papers don’t indicate how many more dogs might have their necks snapped or heads severed by his research team as they boldly and single-mindedly stride toward their goal.
But, again, we’d argue that — no matter what medical gains it could lead to for humans — it should be NONE.

How do things look from a therapy dog’s point of view?
To see things from Hank’s perspective — maybe even better, given Hank’s shaggy bangs — his owner mounted a video camera on the back of the Old English sheepdog.
The five-year-old dog makes his rounds every other week at Seattle’s Children’s Hospital, with his owner, Tom Whalen, according to a hospital blog called “On the Pulse.”
Whalen said hospital stays — especially those lasting weeks or months — can be overwhelming for children. Hank helps bring them some joy and motivation.
“We are able to give them a new focus aside from what they are currently feeling. It’s amazing to see the positive shift in energy for both the patient and their family after Hank walks in,” Whalen says.
Hank and Tom are one of nine dog-human teams that take part in the hospital’s visiting dog program.
As a child, Whalen says, he spent a lot of time in a hospital when his brother was diagnosed with leukemia.
“I remember how my brother loved having visitors,” he said. “This is part of the reason why I love visiting kids at Seattle Children’s. I’m able to see the amazing affect Hank and I can have. I’ve even seen patients whose parents have told me that their child had not smiled or laughed in days or weeks, but as soon as Hank walked in, they lit up with sheer joy.”
The visits do require some preparation, though. The hospital insists visiting therapy dogs be bathed 24-48 hours prior to a visit. That’s no small task with a 78-pound sheepdog, but Hank (if not Tom) always looks forward to it.
He knows it means a visit to the hospital is coming — and he gets even more excited when Tom places a bright orange Seattle Children’s bandana around his neck.
“Some of the reactions I’ve witnessed are remarkable,” said Whalen. “We once visited a patient that had been unresponsive, but a gentle stroke of Hank’s hair encouraged movement and interaction that their family hadn’t seen in days…
“I am just in awe of Hank’s ability to help heal and I am honored to be on the other end of his leash, helping to brighten these kids’ day.”

Specially trained dogs have been alerting diabetics to decreases in their blood sugar levels for years now — but only now do scientists have a pretty good clue of how dogs are able to do it.
Researchers at the University of Cambridge say what the dogs are able to sniff out is a common chemical called isoprene, which is found on our breath.
Isoprene increases significantly — and sometimes almost doubles — during hypoglycemia.
Medical detection dogs wake up or alert their owners whenever their blood sugar level drops to the point of hypoglycemia, a condition that can cause shakiness, loss of consciousness, and, if untreated, death.
Using mass spectrometry, the scientists studied the breath of eight women with type 1 diabetes, noting changes in the chemical signatures of their exhalations when their blood sugar levels were lowered to the point of hypoglycemia.
The increased in isoprene is too subtle for humans to smell, but with the ability to detect odors at concentrations of around one part per trillion, dogs are able to sense it.
The scientists aren’t sure why isoprene increases as blood sugar levels drop, but they suspect it might be a byproduct of cholesterol.
Their findings were published in the July issue of the journal Diabetes Care.
The research could lead the way to developing medical sensors that replicate some of what diabetic alert dogs do, providing diabetics with an alternative to frequent blood testing, said lead researcher, Mark Evans.
“It’s our vision that a new breath test could at least partly – but ideally completely – replace the current finger-prick test, which is inconvenient and painful for patients, and relatively expensive to administer.”

A Florida company that makes synthetic humans for medical training has branched out to synthetic dogs — and it says it’s hoping to place packs of them in every veterinary school in the world.
If successful, SynDaver Labs says, the mission would save thousands of animals by preventing shelter dogs from being used in veterinary training.
SynDaver — a combination of words synthetic and cadaver — wants to raise $24 million to give 20 synthetic dogs to every accredited veterinary medicine college in the world. It says the schools will receive the artificial canines for free.
The company worked with the University of Florida’s College of Veterinary Medicine to develop the synthetic canine, which has a full list of functioning bodily systems, including a heartbeat and a circulatory system. It even bleeds when cut.
Speaking of bodily fluids, fans of the television show “Shark Tank,” may remember the company’s founder, Christopher Sakezles, appearing on an episode last year. Despite sweating profusely — unlike any of the sharks — he managed to persuade one investor to contribute $3 million to his company, in exchange for 25 percent ownership.
The deal later fell through, when Sakezles and investor Robert Herjavec disagreed over specifics. Conjecture is Herjavec wanted to replace the company owner with a new CEO, who would be a more profit focused than Sakezles.
That was last year. This year, the company has announced it will seek backers for the veterinary school program, according to WFLA.
“The product will immediately end the need for terminal surgery labs in veterinary medical schools and represents the beginning of the end of animal testing in general,” the company said.
The synthetic dogs have the capability to simulate customized diseases, illnesses and medical complications, the company says.
If more than $24 million is raised, SynDaver says it will start creating a synthetic cat, followed by a horse and cow.
The Tampa Bay Times described SynDaver as a small player in the $2 billion medical simulation industry, with about 150 employees split between offices in Tampa and Phoenix.

Citing 75 incidents of animal cruelty and a “systemic failure to care for animals,” the N.C. Department of Agriculture on Monday yanked the United Animal Coalition’s license to run animal shelters in Davidson and Guilford counties.
The non-profit organization has been running Guilford County’s animal shelter since 1998, when it was hired by the county to improve conditions.
Seventeen years later, the same sort of allegations have resurfaced during continuing investigations by state and county officials as well as the federal Drug Enforcement Agency.
Department of Agriculture reports mention more than 100 cases of animals receiving inadequate medical care, including a cat with a broken leg and internal bleeding that went seven days without being seen by a vet and a dog with a gunshot wound to the face who went 12 days without medical attention before being euthanized.
The former shelter director in Guilford County, Marsha Williams, was suspended with pay earlier this month. As of yesterday, that pay was halted and Williams was officially terminated under the orders of the county commissioners.
The Guilford County Board of Commissioners convened an emergency meeting Monday, voting unanimously to revoke the United Animal Coalition’s contract and to place the shelter under the county’s control on an interim basis.
A letter of revocation was delivered by hand to the shelter yesterday.
“The things we’ve learned are very disturbing and unacceptable, as I know it is for the community as a whole,” Commissioner Hank Henning, the board’s chairman, said at a press conference after the county commissioner’s meeting. “Our goal is to put transparency and a culture of efficiency back into the shelter, so the community at large can get the services and the shelter that it wants and deserves.”
The N.C. Department of Agriculture has been investigating both shelters for about a month following complaints about animal care and conditions, according to the Greensboro News & Record
The Davidson County investigation began after the state agency received a complaint that a dog had arrived at the shelter with a broken back but received no veterinary care.
The federal Drug Enforcement Agency continues to investigate potential unspecified violations at both facilities.
Also still investigating are the Guilford County Sheriff’s Office and the Lexington Police Department.
“To be quite frank with you, I expect to see criminal charges come out of this,” said Guilford County Sheriff BJ Barnes.
Deputy County Manager Clarence Grier will serve as interim director of the Guilford County shelter, which will remain closed the rest of the week.
The facility is expected to reopen Aug. 22.

A physician’s organization led a rally this week urging Wayne State University to end its long-running series of cardiac research experiments on dogs.
About 45 people joined in the protest, led by the Physicians Committee for Responsible Medicine.
According to the nonprofit organization, the heart failure experiments have been going on for 20 years, at a cost to taxpayers of about $8 million, and have provided no information beneficial to treating human heart disease.
No dogs leave the program alive.
“These research experiments have not garnered anything that has advanced human health,” said Jennifer Giordano, a Detroit-area doctor representing the committee. “We want them to use human-relevant research methods.”
In the experiments, heart problems are induced in the dogs by the use of implanted electrodes, which cause their heart rates to more than double.
The dogs are then put through multiple surgeries and are required to run on treadmills. About 25 percent of the dogs die during or after the surgery. Those who do survive are euthanized when their participation is no longer needed.
The experiments are funded in part by the National Institutes of Health.
At the Wednesday rally the Physicians Committee for Responsible Medicine presented a letter signed by actress Lily Tomlin to Wayne State University officials, calling on them to end medical experiments on dogs. Tomlin is a Detroit native and attended the university.
In the letter, Tomlin wrote: “I understand that Wayne State is spending millions of taxpayer dollars using dogs in heart failure experiments that have not benefited human health in any way. I urge you to end these senseless experiments as soon as possible.”
A copy of the letter was given to Matt Lockwood, a university spokesman who came to the rally and a read a statement defending the experiments, the Detroit News reported.
“Almost every medical advance in the last 100 years was due to research on animals — chemotherapy, hip replacements, transfusions, dialysis — was all tested on dogs,” Lockwood said. “We need to continue to do research to advance science.”
He said the animals in the experiments are under the constant supervision of veterinarians.
“There’s a committee that’s sole purpose is to ensure the animals are as comfortable as possible,” he said. “We’re also under the oversight of the federal government and the state. Never once has any animal been found to have been mistreated at any time.”
He said the dogs are euthanized after taking part in the experiments, but he declined to provide numbers.

Dog blogger and broadcaster Steve Friess says he’s not going to spend $5,000 to put his dog though chemotherapy that could extend his life a year or more — and he’s going to try not to feel bad about it.
Even when he says his final goodbye to Jack in what could be less than a month.
In late October, Friess noticed the dog he’d adopted nine years ago was getting lethargic, and that his weight had dropped from his usual 11 pounds to around eight.
A vet diagnosed that Jack had an aggressive form of lymphoma that was spreading quickly through his body.
Friess did some research, checking with friends, and vets, and friends who were vets: One of the latter urged him to “do the full chemo protocol ASAP!” It could send Jack into remission for nine months, or 12 months, or even longer.
Friess and his partner researched, debated and decided against chemotherapy — not because it would be all that rough on the dog physically (they handle it much better than we do). The main reason, he admits, is the money, which, he also admits, they just doesn’t have.
There will likely be those who second guess Freiss, or maybe try to lay a guilt trip on him: Take out a loan, hit up your friends, get a second (or third) job, launch an online fundraising campaign, let me be the first to donate.
We’ve become a nation of such overflowing compassion for dogs, with such promising new medical technologies, and such handy online fundraising tools at our beck and call, that it’s easy to lose sight that decisions about life and death — both ours and our dogs — are still our own, and that throwing in the towel, for financial reasons, or others, isn’t always a shameful choice.
We suspect Friess will receive some support for his decision, but will hear from many more questioning it. His decision to write about it, as he did in a post for Time.com, is brave, but also an open invitation to second-guessers. In any case, the decision on what’s best for Jack should be (and has been) made by the person who knows him best, and deserves to be respected
Friess, a freelance writer and co-host of The Petcast, said neither his advisers nor his vet seemed to be trying to make him feel guilty about his choice. But, as is the way with guilt trips, we often don’t need a tour guide. Feelings of shame can start as soon as we ask our vet the question Friess did:
“How much will it cost?”
For Friess, the estimate was a minimum of $5,000 — more than he and his partner had.
“(It) means we have about 30 days. The end will probably come in time for holidays … “We’ve received a lot of advice, both solicited and unwelcome, through social media. Nobody comes right out to say it, but the disappointment some express at our decision shows that they question our love for Jack. In an era when people spend big on animal clothes, artisanal foods and medical intervention, and when medical science makes it possible to spend $5,000 so Jack dies slightly later than sooner, there is pressure to go as far as we can.”
There’s one more twist. Friess and his partner are trying to adopt a human baby, and they’re working on saving the $15,000 fee for that.
“If that $5,000 could cure the cancer and restore Jack’s full life expectancy, maybe we’d do it,” he wrote. “Maybe. It certainly would be a tougher choice. But to buy a year during which we’d be waiting for his lymph nodes to resume their swell? We could endure the end stages either now or later.”
