AGRIBUSINESS: Pesticides blamed for rise in colon cancer deaths.

AGRIBUSINESS: Pesticides blamed for rise in colon cancer deaths.The use of pesticides has been linked to a sharp rise in colon cancer deaths in a developing country for the first time. Colon cancer is the third most common type of cancer worldwide, accounting for about 10 per cent of all cases. It is more common in developed nations, but a few countries in Latin America, including Argentina, Brazil, and Uruguay are now approaching the levels of incidence seen in the developed world. Now a team of researchers from Brazil, Germany, and the United Kingdom have mapped the use of pesticides across Brazil between 2000 and 2012. They then compared this to the number of deaths from colon cancer during the same period. They observed an overall increase of colon cancer, which was correlated with the amount of pesticides sold and used in the country. Analyzing data published by the Brazilian Institute of Environment and Renewable Natural Resources, the researchers found that in 2000, just over 162 million tons of pesticides were sold in Brazil. By 2012, sales had jumped to roughly 476 million tons. Over the same period, data gathered by the Brazilian ministry of health indicates that the number of deaths caused by colon cancer had gone up from 946,686 to more than a million, despite progress in cancer detection and treatment. The researchers behind the study said that pesticides applied to Brazilian crops are contaminating food and water consumed by both people livestock.

Organic Food Consumption Lowers Overall Cancer Risks in Large-Scale Study of French Adults.

Organic Food Consumption Lowers Overall Cancer Risks in Large-Scale Study of French Adults.The results are in on one of the first, large-scale studies on organic food consumption and cancer risks and they are significant and encouraging. It is widely recognized we need to do much more in preventing cancer, as opposed to treating it, and this study suggests that organic food may be an important piece of the puzzle. A team of French government scientists analyzed 68,946 citizens in the NutriNet-Santé cohort. Individuals were surveyed to determine if those who ate more organic foods had lower cancer rates. Their new journal article, published online by JAMA Internal Medicine this week (that’s the prestigious journal put out by the American Medical Association), reports their key findings: people consuming organic food most regularly had 25% lower overall cancer risk compared to the group of people reporting very little or no consumption of organic food.

Agribusiness : How to fight cancer naturally with turmeric.

How to fight cancer naturally with turmeric. Extensive research is being conducted in many laboratories across the globe on the anti-cancer properties of turmeric. Being a powerful anti-oxidant, turmeric can protect cells from getting damaged. Turmeric is now being used as a complementary therapy with conventional cancer treatment. Laboratory tests have found that turmeric interferes with many critical molecular pathways that cause the growth and spread of cancer. Recent studies have concentrated on the anti-inflammatory properties of turmeric and if this could help with the prevention and treatment of cancer. Scientists believe that the active ingredient of turmeric, curcumin is a well-known antioxidant and thus help in fighting free radicals which cause cell damage. Turmeric is also known to interfere with several key molecular pathways which lead to cancer development. Turmeric kills cancer cells One of the principal reasons why turmeric is becoming cherished as a health aid is due to its anti-cancer property. Curcumin, the active ingredient in turmeric, has been widely researched upon for its anti-cancer effect. The exact cause of cancer has not been identified but it is thought of as a disturbance in cell signaling pathways that gradually affects proteins that regulate cell life and activity. This disturbance causes the cells to be immortal and hyperproliferative and thus cancer spreads throughout the body. A study published in Biofactors, 2013 states that curcumin’s anti-cancer action is a result of inhibition of cell signaling pathways at multiple levels. A recent study published in Molecules 2015 identifies various targets that curcumin acts on to exert anti-cancer effect and these include :1) Transcription factors (they control the expression of genes) 2)Growth factors. 3)Inflammatory proteins. 4)Cancer causing molecules.5) Various proteins involved in regulation of cell cycle and cell death This multi-faceted action of curcumin makes it a novel anti-cancer agent that holds promise for future treatment options in cancer.

AGRIBUSINESS: Fabián Tomasi, Who Exposed the Toxic Nature of Argentine Agribusiness, Dies.

Fabián Tomasi, Who Exposed the Toxic Nature of Argentine Agribusiness, Dies. Tomasi suffered from a serious illness due to his exposure to pesticides and despite his physical pain, raised his voice to denounce the multimillionaire agribusiness companies responsible .Fabián Tomasi, who contracted severe toxic polyneuropathy due to his exposure to pesticides as an agricultural worker, but fought back by becoming an iconic voice against the impact of agribusiness and toxic chemicals, died on September 7. AGRIBUSINESS: Fabián Tomasi, Who Exposed the Toxic Nature of Argentine Agribusiness, Dies. He had been in hospital for five days after having been diagnosed with pneumonia. Even as his illness inhibited his mobility and caused extreme pain, Tomasi valiantly continued to talk about the impact of chemicals (some of which are illegal), which are widely used in several provinces in the north of Argentina by agribusiness companies. This has led to thousands of cases of cancer, malformations and other related illnesses, which are often ignored or denied by the government and these companies. Below is a piece written by Tomasi in March for La Garganta Poderosa about his life, illness, struggle and about those responsible for the suffering of his community.AGRIBUSINESS: Fabián Tomasi, Who Exposed the Toxic Nature of Argentine Agribusiness, Dies. Many coastal provinces have been destroyed by glyphosate and other chemicals, as if they willingly forgot that we human beings have 70% genetic similarity with plants. How did they expect their poison to tell us apart? They don’t. This is why when they fumigate, only 20% remains in the vegetables and the rest is in the air that we breathe. It is not enough to say “Get out Monsanto,” because the chains of evil today extend to the rest of the multi-million dollar companies and they are tangled up in silence. Today, there are no sicknesses without poison and there is no poison without this criminal collusion between multinational companies, the health industry, the governments and the justice system.

Monsanto knew about glyphosate-cancer link 35 years ago.

Monsanto knew about glyphosate-cancer link 35 years ago. The almighty Monsanto has recently come under fire, after the World Health Organization labeled the main ingredient in the company’s popular Roundup weed killer product to be a human carcinogen. Monsanto is currently in damage control mode in an effort to pick up the pieces from this public relations disaster. In reality, Monsanto has known about the link between glyphosate and cancer for upwards of 35 years. It’s no surprise the evil giant has kept quiet for profit’s sake. The effects of glyphosate on the human body have been studied for years by research scientist Dr. Anthony Samsel, who has revealed the harmfulness of its nature. Samsel has also worked with Dr. Stephanie Seneff, who released a warning that upwards of half of all children in the U.S. could be autistic by year 2025. The impending autism rate will largely be caused by exposure to glyphosate. Samsel was recently given a look into a “trade secret” file that had been sealed away since 1981 at the request of the Monsanto Company. Samsel was able to view the document thanks to his field of study. Though he was not granted permission to show the file to anyone, he is allowed to speak his thoughts on his findings. Samsel was interviewed by journalist Tony Mitra, and spoke about his findings on camera. He talks about disturbing evidence which shows “significant incidences of cell tumors of the tests and tumor growth in multiple organs and tissues” of lab animals. Samsel also discusses the fact that there is evidence that glyphosate enters bone marrow almost immediately. This entry into the bone marrow prevents the formation of new cells in living organisms. Samsel continues to highlight a higher incidence of benign tumors and cancerous tumors that, in almost every single case, begin in outer tissues.

Brazil Judge Suspends Use of Agrochemical Glyphosate.

Brazil Judge Suspends Use of Agrochemical Glyphosate. A Brazilian judge has suspended the use of products containing the agrochemical glyphosate, a widely employed herbicide for soy and other crops in the country, according to legal filings. A federal judge in Brasilia ruled that new products containing the chemical could not be registered in the country and existing registrations would be suspended within the next 30 days, until the government reevaluates their toxicology. The decision, which could be subject to multiple appeals, also applies to the insecticide abamectin and the fungicide thiram. The ruling affects companies such as Monsanto Co, which markets a glyphosate-resistant, genetically-modified type of soybean that is planted on a large scale in Brazil. Monsanto is now a unit of Bayer AG, following a $62.5 billion takeover of the U.S. seed major which closed in June. Certain glyphosate-resistant corn and cotton strains have also been authorized in Brazil.

Cassava Root: Beats cancer instead of Chemo and Radiation! Plus it doesn't kill you!.

#Cassava Root: Beats cancer instead of Chemo and Radiation! Plus it doesn't kill you! #Cassava root has Vitamin B-17 which cures cancer and boosts energy. The method of using the cassava root is as follows; you must remove 3 layers of peeling that is where the dangerous poison is so peel it all the way to the white or you could get cyanide poisoning! The peeled cassava is grated then put in a blender with water and blended until fine. A yellowish fluid is a product of the mix,this is decanted,strained and consumed. If grated peeled cassava is blended or consumed raw and it kills cancer cells then further processing of the grated cassava to produce Garri is equally therapeutic for cancer. The high fiber content of garri promotes bowel emptying thus preventing the risk of colon cancer. This high fiber garri can be processed in several ways to fit different age groups,making it a cheap and better source of wholesome food. Another method is to just grate the cassava that the 3 layer coatings have been removed and just eat. #cassava

When nature gives you Zika virus ... cure cancer with it!.

When nature gives you Zika virus ... cure cancer with it!New research shows that Zika kills the kind of brain cancer cells that are hardest to treat.Each year, glioblastoma is diagnosed in about 12,000 people in the United States (including Senator John McCain). After surgery, chemotherapy and radiation treatment, a small population of glioblastoma stem cells often survives and soon begins producing new tumor cells. Because of their neurological origins and ability to create new cells, glioblastoma stem cells reminded the researchers of neuroprogenitor cells. Zika virus is known to specifically target and kill neuroprogenitor cells. The researchers tested whether the Zika virus could kill stem cells in glioblastomas removed from human patients. The virus spread through the tumors, infecting and killing the cancer stem cells while avoiding other tumor cells. This suggests that Zika infection and chemotherapy-radiation treatment could be used as complementary treatments, with one killing the bulk of the tumor cells and Zika attacking the stem cells.

Curcumin offers potential therapy for cancers caused by HPV.

Curcumin offers potential therapy for #cancers caused by HPV. Curcumin, an antioxidant found in the curry spice turmeric, has been found to slow or limit the activity of the HPV virus, which causes oral and cervical cancers. Turmeric -- the familiar yellow spice common in Indian and Asian cooking -- may play a therapeutic role in oral cancers associated with human papillomavirus, according to new research published in ecancermedicalscience. One of the herb's key active ingredients -- an antioxidant called curcumin -- appears to have a quelling effect on the activity of human papillomavirus (HPV). HPV is a virus that promotes the development of cervical and oral cancer. There is no cure, but curcumin may offer a means of future control. The research indicates that curcumin turns down the expression of HPV in infected oral #cancer cells by downregulating the levels of cellular transcription factors AP-1 and NF-kB. These findings could suggest a new therapeutic role for curcumin in cancer control. #cancer

Anti-cancer properties of soybeans.

Anti-cancer properties of soybeans. The proteins found in soybeans could inhibit the growth of colon, liver and lung cancers according to new research.Soybean meal is a bi-product of oil extraction from soybean seeds and used to feed livestock. It is rich in protein, which usually makes up around 40% of the nutritional components of the seeds and also contain high oleic acid.#soybeans. The study showed the role soybeans could have in the prevention of cancer. Using a variety of soybean lines which were high in oleic acid and protein, the researchers to monitored the bioactivity between the peptides derived from the meals of soybean and various types of human cancer cells. The study showed that peptides derived from soybean meal significantly inhibited cell growth by 73% for colon cancer, 70% for liver cancer and 68% for lung cancer cells using human cell lines. #cancer #soybeans.

RESEARCH: Cancer medicine from cucumbers.

RESEARCH: Cancer medicine from cucumbers. The bitter flavor in wild cucurbits -- the family that includes cucumber, pumpkin, melon, watermelon and squash -- is due to compounds called cucurbitacins. The bitter taste protects wild plants against predators. The fruit and leaves of wild cucurbits have been used in Indian and Chinese medicine for thousands of years, as emetics and purgatives and to treat liver disease. A recent study have shown that cucurbitacins can kill or suppress growth of cancer cells. RESEARCH: Cancer medicine from cucumbers. The new research by University of California - Davis published in science journal has shown that curbing this bitterness made cucumber, pumpkin and their relatives into popular foods, but the same compounds also have potential to treat cancer and diabetes.Bitterness is known to be controlled by two genetic traits, "Bi" which confers bitterness on the whole plant and "Bt," which leads to bitter fruit. This research used the latest in DNA sequencing technology to identify the exact changes in DNA associated with bitterness.The researchers were able to identify nine genes involved in making cucurbitacin, and show that the trait can be traced to two transcription factors that switch on these nine genes, in either leaves or the fruit, to produce cucurbitacin. The new research sheds more light on how domestication changed cucumber genetics to make the fruit more edible. Understanding this process open up new approaches to developing other food crops based on plants that are naturally either inedible or poor in nutrition. #cross breeding #selective breeding #biotechnology.

'Anti-evolution' drugs could be the key to finally curing cancer.

Cancer researchers are coming together to create a new generation of so-called ‘anti-evolution’ therapies, which they say will combat the disease’s “lethal ability to adapt and evade treatment”. Experts from The Institute of Cancer Research in London teamed up with The Royal Marsden NHS Foundation Trust and have launched a roadmap for overcoming what they call ‘the cancer evolution’.The plan sets out how big data analysis can identify cancer’s capacity to sidestep treatment by evolving drug resistance, and uncover game-changing new treatments. Cancers evolve and adapt much as animals and plants do in response to changes in the environment, or bacteria do when they become resistant to antibiotics. Patients may initially respond to cancer treatment, but they often then relapse as their disease evolves and becomes resistant. The scientists will therefore use big data to predict how cancers will evolve and their escape routes from treatment, which they say will allow them to design state-of-the-art clinical trials, assessing the best ways of combining new anti-evolution therapies.

The new rave; 3D PRINTING.

The world is changing,many platforms for growth and development are evolving and joining the train is only sensible. The world of 3d printing is so enormous and the influence in all sectors of the economy makes it a rallying point for the business-oriented individuals. 3d printing has helped in medicine, telecommunication,food industry,clothing, jewelry,cars e.t.c the list is endless and the impact is so amazing. There are surgical procedures that could not be achieved some years back,but thanks to 3Dprinting,lives are saved. This is an open invite to catch the vibe,join the buzz,3d printing is the game-changer. The latest news from the 3d printing world according to 3Dprint.com is that the University of Sheffield is making 3D Printed Micro-Rockets Fueled for Thrust by Enzymes to Deliver Drugs in Human Body.Researchers from Chemical and Biological Engineering at the University of Sheffield are working on it and the process of delivery is astounding. University of Sheffield are responsible for having created a powerful drug delivery system via 3D inkjet printing, working on previous conventions that due to the tools at hand were just too ‘laborious’ to offer great future potential. The use of reactive inkjet printing (RIJ), the researchers expose two different solutions to each other, thus creating a new one or causing a change in form—and here the main result is autonomous, silk-based rockets with varied catalyst distribution and direction of movement. This new technology, technique, and findings, are explained thoroughly in ‘Reactive Inkjet Printing of Biocompatible Enzyme Powered Silk Micro-Rockets,’ by David A. Gregory, Yu Zhang, Patrick J. Smith, Xiubo Zhao, and Stephen J. Ebbens—just published in small. While this concept is not new and studies regarding this basic idea have been going on for at least a decade, University of Sheffield researchers have found a way to streamline it substantially with 3D inkjet printing. As interest has grown in seeing this technology progress, the focus is on applications such as:1)Environmental monitoring and remediation 2) In vivo drug delivery and repair 3)Lab on a chip diagnostics With RIJ technology, there’s much greater potential as compared to lithographic fabrication processes currently ongoing in labs. Through employing the world of 3D technology and printing, they are able to make micro-rockets, composed of silk scaffolds, and ‘highly biocompatible and non-biofouling.’ At 300 microns in length and 100 microns in diameter (as thick as one human hair), the mini-rockets autonomously propel themselves powerfully but they do require bio-fluids acting as their ‘fuel.’ This could have substantial implications in cancer treatment, as feasibly the 3D printed rockets could seek out and destroy cancer cells without causing any detriment to the human body. Not only that, more progressive benefit is found in using this new technology as it’s more affordable than trying to use devices like polystyrene beads, carbon nanotubes or metal, which require a coating such as platinum, and obviously lead to concerns regarding safety within the body. The inket printer’s ‘material’ consists of dissolved silk combined with an enzyme, presented in single droplet form by the MicroFab ‘Drop on Demand’ printer, relying on Jetlab software, and employing four single nozzle print heads (60 μm diameter) which are each attached to their own individual reservoir. The 3D inkjet printer builds up layers of ink, and they are responsible for making a column of the rocket. Beyond that, the researchers have found that the secret is then is exposing the silk to methanol which converts it into a secondary structure allowing for the capture and retention of the enzymes within. The enzyme is then what reacts and acts as the catalyst, with bubbles simply propelling the rocket. Using the silk scaffolds also eliminates the need for surfactant additives. The process is safe, biodegradable, and affordable, offering the true possibility for realistic use in applications such as drug delivery, tissue engineering, and enzyme immobilization. And as the researchers state in conclusion: “…evidenced by much recent research attention, the future potential to further develop these micro-rockets is significant.”

Utah Woman Beats Kidney Cancer Thanks to Progressive Doctors & 3D Printing.

The advent of the 3D printed medical model, many patients and their families now are afforded a look at exactly what’s going on, thanks to completely patient-specific models made from MRI or CT data. In Linda Green’s case, not only did the 3D printed model show her the stubborn tumor lodged inside her kidney, but it may be the reason she is alive today, with the tumor that was sneakily tucked underneath her ribs now a thing of the past The 3D model is not of course just a wonderful educational tool for a patient like Green but it can serve as an invaluable guide for surgeons like Dr. Jay Bishoff. This technology and these incredibly customized visual aids previously not available to doctors, treatments can be decided on with more facts and information in front of them, literally, and procedures that have not been tried before are now possible. Not only that, doctors can train on these aids as well, a new quotient in the treatment process which doesn’t leave surgeons or medical students having to be resourceful for training devices, or spending any more time than possible practicing on cadavers. “We could not appreciate the peak of the tumor that was growing up into the drainage system of the kidney until we did the 3D reconstruction and 3D printing,” Dr. Bishoff said. For Green’s impending treatment and surgery at Intermountain Medical Center, Dr. Bishoff had a clear model made of the kidney and tumor. This allows for surgeons to have a comprehensive view and to avoid the major mistake of removing something vital during the surgery. With the intricate and transparent model, however, Dr. Bishoff was able to remove the tumor without issue, leaving all vital parts intact. He used multiple 3D prints as guides to navigate through the operation, something numerous surgeons are doing today if they have access to the extremely helpful technology. “I could’ve ended up with infection across my outer body or bleeding out,” Green said, definitely understanding the gravity of the procedure. “When the surgery was over and he came out to talk to me, I really thought he was going to tell me that he had to take the kidney out,” Green’s husband said. In a wonderful success story, Green is happy back at her home in Utah, cancer free, and her kidney is completely intact and functioning. The doctors have said that she won’t suffer any damage to the kidney or run the risk of failure. Contributed by 3D print

SOPHIA GENETICS SEQUENCING AND CANCER DIAGNOSIS.

Sophia Genetics detects cancer in the lungs, skin, ovaries and breast, as well as congenital diseases, by sequencing the genomes of patient's tissue samples – then uses machine learning to compare the results and suggest the most effective treatments. Jurgi Camblong,co founder of Sophia genetics is diagnosing cancer using thousands of people's DNA. Hospitals pay each time they use the tool. In its first 18 months, the company was involved in the diagnosis of 25,000 patients. "The problem is not producing the content or the data but really analyzing to find the important information so you can act on a disease," says Camblong. Sophia Genetics's machine learning system, created in 2011, is used in more than 100 hospitals across 20 European countries, including Oxford University's John Radcliffe Hospital and Liverpool Women's NHS Foundation Trust. In 2016, it aims to make 80,000 diagnoses. Once the startup, which has raised more 
than £20 million from investors including Mike Lynch, receives patient data from a hospital, it can find genes related to diseases, such as BRCA-1 in breast cancer, within two hours. Genetic sequencing and treatment is being tackled by some of the world's biggest organisations,,such as Google and Amazon both help scientists analyse genetic data, and the NHS is sequencing 100,000 genomes from 70,000 people. Camblong says 60-person Sophia Genetics' advantage is that it can compare patient data across hospitals. "Algorithms recognize the context in which this raw data has been produced, eliminate biases, and make the results comparable," he says. The company is monitoring the success of each treatment. "In two years time we could tell you that your cancer looks like the cancer of 1,000 other patients, 500 received that drug and 80 per cent survived," says Camblong. It's not the cure - but it's a better diagnosis. read more; wired.co.uk

LABRADOR RETRIEVER AND OBESITY GENE..

A new University of Cambridge study shows that Chubby labrador retrievers may be genetically predisposed to obesity. This research has been published in the journal Cell Metabolism,the dog – which is the most popular breed in the UK – is often considered to be "obsessed with food", say the researchers,this could be explained by the gene. 310 pet and assistance Labradors were weighed, assessed, and given a "body condition score". The team also "searched for variants of obesity-related genes" and assessed food-motivation via a diary kept by dog owners. The research found that one particular gene – POMC – was associated with obesity in the Labradors, with around one in four Labradors thought to carry the gene. It affects how the brain regulates and recognizes the feeling of hunger – meaning the dogs may carry on eating when they're full. "This is a common genetic variant in Labradors and has a significant effect on those dogs that carry it, so it is likely that this helps explain why Labradors are more prone to being overweight in comparison to other breeds," said Eleanor Raffman, lead author of the research. "People who live with Labradors often say they are obsessed by food, and that would fit with what we know about this genetic change." The team says the research may also have an impact on our understanding of human obesity. "Common genetic variants affecting the POMC gene are associated with human body weight and there are even some rare obese people who lack a very similar part of the POMC gene to the one that is missing in the dogs. So further research in these obese Labradors may not only help the well being of companion animals but also have important lessons for human health," said Stephen O'Rahilly, who also worked on the research. Obesity in dogs can cause diabetes, heart disease, cancer and a reduced lifespan as also observed in man. culled from wired.co.uk

Yeast Can Now Produce THC, Marijuana’s Infamous Compound,cannabidiol .

Yeast, the sugar-gobbling microorganism that’s filled our bellies with beer and bread for millennia, has a new, increasingly important, role to play in society: serving as a therapeutic drug factory. In August, scientists announced they had genetically engineered yeast to produce the painkiller hydrocodone, and even before that breakthrough, modified yeast churned out the anti-malarial drug artemisinin. Now, scientists have customized yeast to create THC (the marijuana chemical that produces a “high”) and cannabidiol Biochemists from the Technical University in Dortmund, Germany, created a genetically-engineered yeast strain to produce very small amounts of THC or cannabidiol. Unlike normal yeast, however, these custom yeast have to be fed cannabigerolic acid, which is a precursor molecule to THC and cannabidiol. Using a molecular precursor as a starting point is a bit like reading a book from the middle chapters to its conclusion. Ideally, the entire process would start with simple sugars — or chapter 1 — rather than precursors to complete the entire chemical pathway that the marijuana plant does naturally. However, scientists believe they’ll get to that point and scale up production for industrial use in the near future, the New York Times reports. The team published its work with the yeast strain that produces THC in the journal Biotechnology Letters. They also created a separate strain that produces cannabidiol, but those data are yet to be published. Marijuana is chock full of molecular compounds that are fascinating to scientists. Synthetic THC is already available in pill form and it is used to ease nausea in cancer patients undergoing chemotherapy, or stimulate the appetites of people with H.I.V. or other infections. Cannabidiol, a compound that is not psychoactive, has shown potential to reduce the frequency of seizures in epileptic individuals. Yeast factories could help scale up production of these chemicals not just for therapy, but for research too. Producing marijuana’s constituent compounds in vast quantities would give researchers a supply of marijuana’s myriad chemicals to better understand how, or if, they work as advertised. Still, at the moment, the plant is far more efficient than the yeast — modern marijuana strains can contain more than 30 percent THC by dry weight. So there’s still a long way to go before THC-producing yeast change the landscape of cannabis research. Researchers will likely need to splice many more genes into species of yeast to complete the entire chemical reaction in a single strain. But at the rate that genetically-modified yeast research is advancing, it may not be a long wait. culled from science for the curious Discover.
