'An experimental dermal implant changes color in the presence of high acidity or blood glucose, potentially allowing diabetics and other patients to monitor their wellbeing without taking samples. The implant material can be integrated into tattoo ink formulations, making them as discrete or ostentatious as the wearer wishes. MedicalXPress : As detailed in the journal Angewandte Chemie, a colorimetric analytic formulation was injected into the skin instead of tattoo ink. The pigmented skin areas varied their color when blood pH or other health indicators changed. .. The authors claim that such sensor tattoos could allow permanent monitoring of patients using a simple, low-cost technique. With the development of suitable colorimetric sensors, the technique could also extend to recording electrolyte and pathogen concentrations or the level of dehydration of a patient. Further studies will explore whether tattoo artwork can be applied in a diagnostic setting.'

'The manufacturing costof a dental implant is less than 50 dollar, however dental implants cost onaverage 900 dollars, and in reality you will need to pay about 2500 US dollars toreplace a lost tooth. How is that ? Dentists are notscamming their patients but they have such high rates because they have to pay assistants,nurses, clinic, taxes, insurance and that increases the bill. Thanks to an articlefrom Newdentaire.be , which we translated an summarize here, youwill understand the price of dental implants. How much does a dental implant reallycost? For the replacement ofa tooth, nothing beats a dental implant: this Titanium screw implanted in thejaw on which crown is placed. The implant surgery isjust one of the many steps you need to go through: • You will start witha panoramic X-ray and a dental scanner to find out if your jawbone can accommodatethe implant (about 300 dollars). • To prepare thesurgery, teeth are scaled in order to avoid infections (150 dollars onaverage). • One every threeperson will need a bone graft to add bone before placing the implant (about1500 dollar). • Then, the implant is900 dollars on average. • Finally, the crownis the only part you really see once the work is done. A crown is easily paid 700dollars. The total amountexceeds 2000 dollar in most cases for one single tooth. Why is the price so high? 500 USD of materialfor a 2500 dollar implant: By visiting a dentalsalon, we discovered the true price that dentists pay for implants, crowns andthe material used to add bone. • An implant costsabout 120 USD (Manufacturing cost is about 50 but that is purely themanufacturing cost, it does not include the other costs such as advertising,communication and profit). • In a dental crownthere is less than 100 dollar of material (however the technologies used arevery expensive: CNC machining, 3D scanner, 3D printer) • The artificial boneis worth about 200 dollars. Does your dentist make a 2000 dollarprofit? Actually no, it takesa huge amount of work to replace a tooth by a dental implant. People who havealready been through this know that it takes between 5 and 10 appointments atthe dentist to rebuild a tooth. The dentist must alsopay the rent for his workspace, his professional insurance and possibly asecretary. In addition, theprosthetist must invest in many very precise machines to perfectly achieve eachtooth. It’s a tailor-made job with high precision. Imagine that your new toothhas to adapt to both the implant, but also the neighboring teeth and theopposite one. Finally, there is thestate’s share. The dentist and theprosthetist share what is left, but given the number of hours of work and theinvestments it represents, it is far from the highest paid work in the world. Is Dental tourism a scam? The analysis of theprice of a dental implant shows that the price depends much more on labor andtaxes than on the initial cost of the necessary equipment and materials. That explains howdentists in some countries in Eastern Europe manage to lower the price ofdental implants. The case of dental clinics in Romania As an example we willnow compare 2 European countries such as France and Romania because they areabout 2 hours apart by plane and they are both in the EU. In France, the fullcost of a dental implant is about 2000€ whereas the same implant only costs1150€ in Romania.  In Romania,corporate profits tax is 16%, which is half of what a French dentist pays. VATis 19% instead of 21%. In terms of manpower:the average salary in Romania in 2018 is € 573, about 4 times less than inFrance. The rent of acommercial space is also half price, compared to France, without counting thebig cities like Paris or Lyon where the rents are overpriced. If we do the samecalculation for a dental implant in Romania we get: • The equipment isalways at the same price because a good dentist or oral surgeon gets hismaterial from major international brands : about 300 €. • The operation of theclinic costs only 200 €. • Labor costs only 250€. • Taxes are worth 400€. It is therefore a totalof 1150 € for a dental implant in Romania against 2000 € in France. That is apotential saving of more than 40% for this dental treatment.'

1960s Prankster Paul Krassner, Who Named Yippies, Dies at 87

Health care Voice of America

He was 87 and had recently transitioned to hospice care after an illness
'Paul Krassner, the publisher, author and radical political activist on the front lines of 1960s counterculture who helped tie together his loose-knit prankster group by naming them the Yippies, died Sunday in Southern California, his daughter said.  Krassner died at his home in Desert Hot Springs, Holly Krassner Dawson told The Associated Press. He was 87 and had recently transitioned to hospice care after an illness, Dawson said. She didn't say what the illness was.  The Yippies, who included Jerry Rubin and Abbie Hoffman and were otherwise known as the Youth International Party, briefly became notorious for such stunts as running a pig for president and throwing dollar bills onto the trading floor of the New York Stock Exchange. Hoffman and Rubin, but not Krassner, were among the so-called \'Chicago 7'' charged with inciting riots at 1968's chaotic Democratic National Convention.  By the end of the decade, most of the group's members had faded into obscurity. But not Krassner, who constantly reinvented himself, becoming a public speaker, freelance writer, stand-up comedian, celebrity interviewer and author of nearly a dozen books.  \'He doesn't waste time,'' longtime friend and fellow counterculture personality Wavy Gravy once said of him. \'People who waste time get buried in it. He keeps doing one thing after another.'' He interviewed such celebrity acquaintances as authors Norman Mailer and Joseph Heller and the late conservative pundit Andrew Breitbart. The latter, like other conservatives, said that although he disagreed with everything Krassner stood for, he admired his sense of humor.  An advocate of unmitigated free speech, recreational drug use and personal pornography, Krassner's books included such titles as ``Pot Stories For The Soul'' and ``Psychedelic Trips for the Mind,'' and he claimed to have taken LSD with numerous celebrities, including comedian Groucho Marx, LSD guru Timothy Leary and author Ken Kesey.  He also published several books on obscenity, some with names that can't be listed here. Two that can are ``In Praise of Indecency: Dispatches From the Valley of Porn'' and \'Who's to Say What's Obscene: Politics, Culture & Comedy in America Today.''  For his autobiography, Krassner chose the title, \'Confessions of a Raving, Unconfined Nut: Misadventures in the Counterculture,'' using a phrase taken from an angry letter to the editor of a magazine that had once published a favorable profile of him.  \'To classify Krassner as a social rebel is far too cute,'' the letter writer said. \'He's a nut, a raving, unconfined nut.'' What he really was, Krassner told The Associated Press in 2013, was a guy who enjoyed making people laugh, although one who brought a political activist's conscience to the effort.  In this May 7, 2009, file photo, author, comedian and co-founder of the Yippie party as well as stand-up satirist, Paul Krassner, 77, poses for a photo at his home in Desert Hot Springs, Calif. He noted proudly that in the early 1960s, when abortion was illegal in almost every state, he ran an underground abortion referral service for women.  \'That really was a turning point in my life because I had morphed from a satirist into an activist,'' he said.  His original career choice, however, had been music.  A child prodigy on the violin, he performed at Carnegie Hall at age 6. Later he all but gave up the instrument, only occasionally playing it as a joke during lectures or comedy routines.  \'I only had a technique for playing the violin, but I had a real passion for making people laugh,'' he would say.  After studying journalism at New York's Baruch College, Krassner went to work for Mad Magazine before founding the satirical counterculture magazine The Realist in 1958. He continued to publish it periodically into the 1980s.  For a time in the 1950s, he also appeared on the stand-up comedy circuit. There, he would meet his mentor, Lenny Bruce, the legendary outlaw comic who pushed free speech to its limits with routines filled with obscenities and sexual innuendo that sometimes landed him in jail.  Krassner interviewed Bruce for Playboy Magazine in 1959 and edited the comedian's autobiography, \'How To Talk Dirty and Influence People.''  When the counterculture arrived in earnest in the '60s, Krassner was working as a comedian, freelance writer, satirist, publisher, celebrity interviewer and occasional creator of soft-core pornography. To mark the death of Walt Disney in 1966, he published a colorful wall poster showing Disney cartoon characters engaging in sex acts.  When he and other anti-war activists, free-speech advocates and assorted radicals began to plot ways to promote their causes, Krassner said he soon realized they would need a clever name if they wanted to grab the public's attention.  \'I knew that we had to have a `who' for the `who, what, where, when and why' that would symbolize the radicalization of hippies for the media,'' Krassner, who co-founded the group, told the AP in 2009. ``So I started going through the alphabet: Bippie, Dippie, Ippie, Sippie. I was about to give up when I came to Yippie.''  As one of the last surviving Yippies, he continued to write prolifically up until his death, his daughter said.  His newest book, \'Zapped by the God of Absurdity,'' will be released later this year. And he recently wrote the introduction for an upcoming book about his old friend Abbie Hoffman, Dawson said.  Krassner also had hoped to publish his first novel, a mystery whose protagonist is a crime-solving comedian modeled after Lenny Bruce. He got so into the story, Krassner once said, that he began to believe he was channeling Bruce's spirit. That ended, however, when the spirit reminded his old friend one day that Krassner was an atheist.  \'He said to me, 'Come on, you don't even believe that (expletive),''' Krassner recalled with a laugh.  He is survived by his wife, Nancy Cain; brother, George; daughter, Holly Krassner Dawson; and one grandchild.'
