Kill the Cancer Stem Cell, Kill the Cancer: How One Biotech is Hitting Cancer at the Cause

Posted by in categories: biotech/medical, innovation

TORONTO, ON / ACCESSWIRE / January 10, 2019 / The Wealthy Biotech Trader (or” WBT”), an investment newsletter focused on showing everyday investors new opportunities in rapidly growing, little-known biotech, pharma, medical device stocks making news and subsequent market moves, would like to update investors on several breakthroughs in cancer therapies hitting the market.

Stock investors have soured on biotech companies over the past several months, as demonstrated by the SPDR S&P Biotech ETF (XBI), off 30% since June, and the NYSE Biotechnology Index (NYSE: NBI), which has dropped from 3500 in mid-2018 to just under 3000 at year-end, and a host of their component companies and others in addition. Still, there is innovation and competitive potential brewing in the market at publicly-traded companies that are flying below the radar. One of those is Propanc Biopharma, Inc. (OTCQB: PPCB), an Australian biotech company with strong management and technology that has the potential to help millions of cancer patients worldwide.

Fighting Deadly Drug Resistant Bacteria in Intestines with New Antibiotic

Posted by in categories: biotech/medical, life extension

A new antibiotic developed by a Flinders University researcher is being heralded as a breakthrough in the war against a drug resistant superbug. Bacteria are winning the fight against antibiotics as they evolve to fight off traditional treatments, threatening decades of advancements in modern medicine, with predictions they will kill over 10 million people by 2050. The scientific development of new, effective and safe antibiotics is crucial in addressing the ever-growing threat posed by drug resistant bacteria around the world.

Clostridium difficile infection (CDI) is a potentially deadly infection in the large intestine most common in people who need to take antibiotics for a long period of time, particularly in Australia’s ageing population. Dr Ramiz Boulos, adjunct research associate at Flinders University and CEO of Boulos & Cooper Pharmaceuticsals, says the fact CDI is becoming resistant to traditional antibiotics is alarming and highlights the need to develop more effective treatments.

“Cases of CDI disease are rising and the strains are becoming more lethal. If there is an imbalance in your intestines it can begin to grow and release toxins that attack the lining of the intestines which leads to symptoms,” says Dr Boulos. Over the past ten years, various strains of C. difficile have emerged, and are associated with outbreaks of severe infections worldwide. One particular strain is easily transmitted between people and has been responsible for large outbreaks in hospitals in the United States and Europe. “It’s concerning when you consider CDI is one of the most common infections acquired during hospital visits in the Western hemisphere, and the most likely cause of diarrhea for patients and staff in hospitals.”

How Long Will We Live in 2069?

Posted by in categories: biotech/medical, genetics, life extension, neuroscience

A new, very good article on aging, modern aging research and its history, RAAD feest and other initiatives, on model organisms, genetics and future lifespans. “… In early December 2018, just a few months after RAADfest, I visited the Buck Institute for a daylong symposium titled “Live Better Longer: A Celebration of 30 Years of Research on Aging.” That wasn’t an arbitrary demarcation: Aging is one of the rare areas of modern science with a specific launch date. In this case, it was January 1988, when Tom Johnson, a behavioral geneticist at the University of California, Irvine, published a paper that linked a genetic mutation he named “age-1” to longer lifespans in a transparent, microscopic, mostly hermaphroditic roundworm known in scientific circles as C. elegans. Prior to Johnson’s discovery, aging had not received a lot of attention from researchers. In the 1820s, Benjamin Gompertz, a self-trained mathematician, concluded that humans don’t start to break down at some magic age but are constantly declining and losing the ability to repair themselves, a concept now referred to as the Gompertz law of mortality. The first hint that there might be a cellular mechanism underlying the aging process came more than a century later, in the 1930s, when two Cornell scientists discovered that rats kept on calorically restricted diets lived significantly longer than their more satiated brethren. But overall, the field was mostly known as being a haven for charlatans and quacks peddling immortality elixirs and other magical cures — a reputation that continued even after Johnson’s work was published…In 1993, Cynthia Kenyon, an assistant professor at the University of California, San Francisco, discovered that mutations on a different gene, called daf-2, caused C. elegans to live twice as long as expected. Several years later, Gary Ruvkun, a researcher at Harvard Medical School, showed that these so-called worm-aging genes were closely related to genes in the insulin-signaling system of humans. Around the same time, MIT’s Guarente and some of his colleagues discovered the first of several genes in yeast — which are also present in humans — linked to dramatically extended lifespan…” https://medium.com/s/2069/how-long-will-we-live-in-2069-f03e698f6de2


With this promising research on the horizon, how long might humans live in the future? Fantastical claims to longevity have existed since the dawn of recorded time, but reliable data about maximum human lifespan only dates to the mid-1950s, when the Guinness Book of World Records began independently verifying claims. Even then, initially corroborated ages can end up disproven: On December 27, Russian researchers published a paper arguing that the current world record holder, a Frenchwoman named Jeanne Calment, who said she was 122 when she died in 1997, had stolen her mother’s identity and was actually 99 at the time.

Assuming Calment wasn’t a fraud, since 1955, 46 people have made it to age 115. Nine of them have made it to 117 — and only two, Calment and an American woman named Sarah Knauss, have made it past 117. (Knauss died in 1999 at age 119). Over that same time frame, just under 11 billion people have been alive. That means roughly .0000004204133 percent of people have made it to 115. You’re 79,333 times more likely to get hit by lightning than you are to live to 115; 22,455 times more likely to end up in the emergency room from a golf cart accident; and 11,817 times more likely to get murdered.

Industrial chemicals pass from mother to fetus throughout pregnancy

Posted by in categories: biotech/medical, food, neuroscience

In a study published in Environment International researchers at Karolinska Institutet in Sweden show how PFAS industrial chemicals, which are used in many consumer products, pass through the placenta throughout pregnancy to accumulate in fetal tissue. Further research is now needed to ascertain the effect that highly persistent PFAS chemicals have on the fetus.

The PFAS () group comprises thousands of human-made chemicals, which, thanks to their water- and grease-resistant properties, are used in everything from frying pans and food packaging to clothes, cleaning agents and firefighting foams.

“We’ve focused on six of these PFAS substances and found that all appear to the same extent in as in the placenta,” says Richelle Duque Björvang, doctoral student at the Department of Clinical Science, Intervention and Technology, Karolinska Institutet. “So when the baby is born, it already has a build-up of these chemicals in the lungs, liver, brain, and elsewhere in the body.”
