Made-To-Order Cartilage Could Combat Osteoarthritis About 27 million people in the United States suffer from osteoarthritis. This can result in pain, swelling, and eventually even loss of motion in the joint. Knees and joints in the hand are particularly affected. While there are pain relievers and medications capable of of treating the symptoms of osteoarthritis, there is nothing currently available to reverse or cure the disease. “Osteoarthritis has a severe impact on quality of life, and there is an urgent need to understand the origin of the disease and develop effective treatments,” Taun stated. In hopes of developing a new form of treatment, Taun sought to manufacture replacement cartilage derived from the patient’s own stem cells that could be added into the joint. Taun’s lab made another huge advancement by creating a 3D printed model of the interface of bone and cartilage, which may one day give scientists a unique opportunity to study how the disease develops, progresses, and how it can be treated with new drugs.
Circadian rhythm Some features of the human circadian (24-hour) biological clock History The earliest recorded account of a circadian process dates from the 4th century B.C.E., when Androsthenes, a ship captain serving under Alexander the Great, described diurnal leaf movements of the tamarind tree. The observation of a circadian or diurnal process in humans is mentioned in Chinese medical texts dated to around the 13th century, including the Noon and Midnight Manual and the Mnemonic Rhyme to Aid in the Selection of Acu-points According to the Diurnal Cycle, the Day of the Month and the Season of the Year. The first recorded observation of an endogenous circadian oscillation was by the French scientist Jean-Jacques d'Ortous de Mairan in 1729. The term circadian was coined by Franz Halberg in the 1950s. Criteria To be called circadian, a biological rhythm must meet these three general criteria: Origin The simplest known circadian clock is that of the prokaryotic cyanobacteria.
How 3-D Printing Can Help To Cure Cancer When scientists test drugs on cancer cells, they do so in the two-dimensional confines of the Petri dish. If the drug being tested works well, the next stage is to shift to the 3-D environment and see how the drug tackles 3-D tumors in animals. If that goes well, then, finally, researchers start clinical trials on humans. But what if testing and treatment could start in 3-D? The answer may lie in 3-D printing. According to Sun, there's just as huge a disconnect between what works in two versus three dimensions as there is between what works in animals versus humans. With Sun's 3-D printing technology, a living tumor can be printed just as easily as cancer cells grow in a Petri dish. But testing cancer drugs more easily is only one of the many uses of Sun's technology. "Doctors want to be able to print tissue, to make organ on the cheap," Dr. So far, we've been fighting the war on cancer in flatland, but thanks to 3-D printing, the battle's about to take on an entirely new dimension.

This proof-of-principle study means that one day, heart cells beating in a dish would allow survivors of severe episodes to have properly working hearts. A common type of heart attack called myocardial infarction blocks blood flow in major arteries and deprives muscles of oxygen, weakening the vital pump’s abilities. Charles Murry and colleagues from the University of Washington wanted to see if cardiomyocyte transplantation could work in larger primate hearts. Then, to create the infarction, they blocked the coronary artery of pigtail macaques for 90 minutes using a catheter and a small balloon. The transplanted cells also remuscularized the failing hearts: New muscle grew up to 0.6 inches wide, and on average, 40 percent of the damaged heart tissue was regenerated. The work was published in Nature this week.
| 5 Common Food Items That Could Save Your Life From the Team at Green Med Info… Some of the most powerful medicines on the planet are masquerading around as foods and spices. While they do not lend themselves to being patented, nor will multi-billion dollar human clinical trials ever be funded to prove them efficacious, they have been used since time immemorial to both nourish our bodies, and to prevent and treat disease. So valued were these in ancient times that they were worth their weight in gold, and entire civilizations either rose to great power or collapsed as a result of their relationship to them. What is even more amazing is that many of these “plant allies” are found growing in our backyards, and often sitting there in our refrigerators and spice racks, neglected and under appreciated. This amazing list underscores how important it is to keep a supply of garlic close by! 2.) There are many more uses for honey than covered here.

3D Printed Device Detoxifies Blood Like a Liver Okay, it doesn’t look like a liver, but this new 3D printed device can detoxify the blood like one. While it’s just a proof-of-concept, nanoengineers hope the liver-inspired device can be used like a dialysis one day. Animal bites, stings, and bacterial infections can leave behind toxins in the blood that form pores and damage cellular membranes. Previous work has shown how nanoparticles can neutralize these pore-forming toxins -- but they end up accumulating in the liver. That could to lead secondary poisoning, which pretty much defeats the whole point. This new device uses nanoparticles to trap those toxins, preventing any illnesses that may result. The biofabrication technology used is called dynamic optical projection stereolithography, and it uses a projection system and tiny mirrors to shine a light on photosensitive biopolymers and cells in a solution.
Flavors.me : The Digital You New Element Confirmed The periodic table has been extended, with the announcement of the confirmation of the yet to be named element 117. In 2010 a US Russian collaboration announced they had produced atoms of an element with 117 protons, filling a gap that appeared when 118 was made four years earlier. However International Union of Pure and Applied Chemistry (IUPAC) insists on corroboration by two independent teams before it allows new elements to be added to the Periodic Table, although a temporary name of Ununseptium is in use until confirmation has been made. It has taken four years, but this appears to have finally arrived. “Making element 117 is at the absolute boundary of what is possible right now,” says Professor David Hinde of the Australian National University, one of the authors of a paper published today in Physics Review Letters “That’s why it’s a triumph to create and identify even a few of these atoms.” The manufacturing process was hardly efficient. Meanwhile Hinde has still greater dreams.
Yin Yoga 101: What You Need to Know Yin Yoga, a less popular style of yoga in the west is an approach that some may have never even heard of. One that in my experience, takes many a few times to really warm up to and even understand. Initially called “Daoist” yoga this style of yoga targets the deep connective tissues of the body (vs. the superficial tissues) and the fascia that covers the body; this Daoist yoga is to help regulate the flow of energy in the body. Paul Grilley, who brought this concept to the forefront, accredits three main teachers for this concept, one of which is Paulie Zink, who taught him Daoist Yoga. Yin Yoga postures are more passive postures, mainly on the floor and the majority of postures equal only about three dozen or so, much less than the more popular yang like practices. So what exactly is Yin yoga? Now if you’ve never practiced Yin yoga you might not quite understand how this is so different, but for me Yin has dug deeper than I could have ever gotten otherwise.
3D Printed Body Parts Go Mainstream 3D printing technology has been around for two decades, but the price has come down in recent years and more people have been able to make use of it. Consequently, we've started to be able to really tap into its vast potential. 3D printed products are being spewed out left, right and center; from the building blocks of houses to replica shark skin. It almost seems as though the capabilities are endless, and the technology is not anticipated to slow down any time soon. One really exciting application of 3D printing is the generation of body parts. The level of detail that this technology can produce often supersedes that of traditional methods, offering patients a superior fit or design, and they can often be produced at an impressively low cost. Researchers have turned to 3D printing to produce a wide variety of body parts. Image credit: Washington University in St Louis. Image credit: Not Impossible/ Project Daniel.
