    Research in mice shows limited intakes of one particular essential amino acid can slow the impacts of aging and even lengthen their lifespan. Scientists are now wondering if these findings could help people improve their longevity and quality of life. Isoleucine is one of three branched-chain amino acids we use to build proteins in our bodies. It is essential for our survival, but since our cells can't produce it from scratch, we have to get it from sources like eggs, dairy, soy protein and meats. But there can always be too much of a good thing. Earlier research using data...
  • A naturally-occurring molecule shows promise as effective first-line treatment for prostate cancer (Carnosine)

    Scientists wanted to investigate the anti-cancer properties of carnosine against cells derived from both primary and metastatic prostate cancer. Carnosine, which can be produced by the body and is also found in meat, has long been advocated for use as an antioxidant to facilitate healthy aging. There have been reports of carnosine being effective against the development of a number of different cancers but this is the first time it has been studied in relation to prostate cancer. The researchers found that carnosine stopped the cells from multiplying and at higher doses even killed cancer from both primary and metastatic...
  • Researchers identify amino acid that may play a key role for predicting and treating long COVID (Taurine)

    Researchers have identified an amino acid that may play a key role in predicting poor clinical outcomes and the treatment of long COVID. In research, the team says it has developed a predictive test to determine which patients with COVID-19 will go on to develop longer-term symptoms and proposes a clinical trial of an already-approved supplement as a potential treatment. "This research helps us understand what's happening in the bodies of people with long COVID and could lead to better treatments," says Gavin Oudit. The team followed 117 patients who were admitted to hospital with acute COVID-19, taking blood samples...
  • British scientists are growing a new strain of WHEAT that has been genetically edited to reduce levels of asparagine – an amino acid linked to cancer when bread is toasted

    It will be the first time wheat created using a gene editing technique known as CRISPR has been grown in fields in the UK or Europe, although it is in use in China and the US. He said acrylamide has been a very serious problem for food manufacturers since it was first discovered in 2002, shown to cause cancer in rodents, and has been considered 'probably carcinogenic' for humans. 'It occurs in bread and increases substantially when the bread is toasted, but is also present in other wheat products and many crop-derived foods that are fried, baked, roasted or toasted,...
  • Study shows inexpensive, readily available chemical may limit impact of COVID-19 (GABA amino acid supplement)

    10/25/2022 9:03:40 PM PDT · by ConservativeMind · 18 replies
    Preclinical studies in mice that model human COVID-19 suggest that an inexpensive, readily available amino acid might limit the effects of the disease and provide a new off-the-shelf therapeutic option for infections with SARS-CoV-2 variants and perhaps future novel coronaviruses. Researchers report that an amino acid called GABA, which is available over-the-counter in many countries, reduced disease severity, viral load in the lungs, and death rates in SARS-CoV-2-infected mice. Said Daniel Kaufman: "If our observations of the protective effects of GABA therapy in SARS-CoV-2-infected mice are confirmed in clinical trials, GABA could provide an off-the-shelf treatment to help ameliorate infections...
  • Newly-Synthesized Peptide Could Disarm SARS-CoV-2 Coronavirus

    Chemists at the Massachusetts Institute of Technology (MIT) have chemically synthesized a new peptide (a short protein fragment) that can bind to part of SARS-CoV-2's spike protein, a key protein responsible for getting the virus into mammalian cells, potentially disarming it. "We have a lead compound that we really want to explore, because it does, in fact, interact with a viral protein in the way that we predicted it to interact, so it has a chance of inhibiting viral entry into a host cell," said senior author Dr. Brad Pentelute, a researcher in the Department of Chemistry at MIT. Coronaviruses,...

    Amino acids are the building blocks of proteins. Tryptophan and methionine are essential amino acids -- the diet must provide them because cells cannot make them. Normally, the lack of an essential amino acid in the diet can lead to serious diseases and even death. Foods rich in tryptophan and methionine include cheese, lamb, beef, pork, chicken, turkey, fish, eggs, nuts and soybeans.

    The parents of an eight-year-old boy with a rare blood disorder have amazed doctors by finding a cure for him after refusing to give up hope. Reuben Grainger-Mead suffered a condition so rare that doctors did not even have a name for it. The schoolboy suffered from a low level of red blood cells, which left him with a weak immune system and needing blood transfusions once a month. Doctors compared his condition to living with a permanent hangover. But after years of research his parents Michelle and Peter, discovered Reuben lacked vital amino acids and proteins and put him...

    Washington, Oct 06: A meteorite, which crashed into Australia 40 years ago, is telling researchers new things about how life may have started on Earth, and how that almost universal protein left-handedness came to be. For more than 150 years, scientists have known that the most basic building blocks of life - chains of amino acid molecules and the proteins they form - almost always have the unusual characteristic of being overwhelmingly “left-handed.” The molecules, of course, have no hands, but they are almost all asymmetrical in a way that parallels left-handedness. This observation, first made in the 1800s by...
  • U.S. Demand for Human Hair Grows, Used in Wigs, Pizza

    About 15 tons of it on a recent day, imported from China, neatly pressed into mats and ready to ship to farmers and nursery growers who swear by the horticultural benefits of Blacker's hairy wares. The mats stored in southern Miami-Dade County are part of a world marketplace for human hair. Uses range from the obvious, such as false eyelashes and wigs, to the more obscure: it's a common raw-material source for l-cysteine, an amino acid frequently used in baked goods such as pizza dough and bagels
