A non-profit warns EPA against expanding the use of oxyteracycline as pesticide (downtoearth)

On May 10, the Center for Biological Diversity along with Johns Hopkins Center for a Livable Future sent their comments to the Environmental Protection Agency (EPA), asking the regulatory agency to not expand the use of a medically important antibiotic for citrus crops.

A US crop protection company, Nufarm Americas Inc., had sought registration of an antibiotic, oxyteracycline, for use in citrus crops and in dried citrus pulp from the EPA. The agency called for comments from the public by May 10.

The Centre said in its press release that Nufarm Americas Inc. has already been permitted emergency exemption to use the antibiotic in Mycoshield to treat citrus greening disease in Florida starting January 2017 till end of the year. The release added that exposure to antibiotics can have serious unintended side effects on wildlife, including adverse drug reactions, and can also cause changes in the chemical composition and pH of water and soil with potentially serious consequences.

“Since tens of thousands of people are dying every year as a result of antibiotic-resistant infections, it’s outrageous that the EPA is allowing, and may even expand, the use of antibiotics as pesticides,” said Hannah Connor, a senior attorney at the Center. “This is a careless, shortsighted practice that contributes to the reduced effectiveness of these drugs.”

Interestingly, dried citrus pulp is fed to cattle for beef production in the US. This is akin to cattle consuming antibiotics laden feed. The WHO recognises that the misuse of antibiotics in the production of food-producing animals also contributes to the spread and rise of antibiotic resistance.

Antibiotic resistance is a global health concern today. While resistance to antibiotics is a natural phenomenon, the misuse of antibiotics in agriculture is recognised as a factor which speeds the development of resistance in bacteria. The Center for Disease Control and Prevention estimates that more than 2 million people are infected with antibiotic-resistant organisms each year, leading to an estimated 23,000 deaths.

SC asks Centre to strike a balance on Rohingya issue (.hindu)

Supreme Court orally indicates that the government should not deport Rohingya “now” as the Centre prevails over it to not record any such views in its formal order, citing “international ramifications”. The Supreme Court on Friday came close to ordering the government not to deport the Rohingya. It finally settled on merely observing that a balance should be struck between humanitarian concern for the community and the country's national security and economic interests. The court was hearing a bunch of petitions, one filed by persons within the Rohingya community, against a proposed move to deport over 40,000 Rohingya refugees. A three-judge Bench, led by Chief Justice of India Dipak Misra, began by orally indicating that the government should not deport Rohingya “now”, but the government prevailed on the court to not pass any formal order, citing “international ramifications”. With this, the status quo continues even though the court gave the community liberty to approach i...

High dose of Vitamin C and B3 can kill colon cancer cells: study (downtoearth)

In a first, a team of researchers has found that high doses of Vitamin C and niacin or Vitamin B3 can kill cancer stem cells. A study published in Cell Biology International showed the opposing effects of low and high dose of vitamin C and vitamin B3 on colon cancer stem cells. Led by Bipasha Bose and Sudheer Shenoy, the team found that while low doses (5-25 micromolar) of Vitamin C and B3 proliferate colon cancer stem cells, high doses (100 to 1,000 micromolar) killed cancer stem cells. Such high doses of vitamins can only be achieved through intravenous injections in colon cancer patients. The third leading cause of cancer deaths worldwide, colon cancer can be prevented by an intake of dietary fibre and lifestyle changes. While the next step of the researchers is to delineate the mechanisms involved in such opposing effects, they also hope to establish a therapeutic dose of Vitamin C and B3 for colon cancer stem cell therapy. “If the therapeutic dose gets validated under in vivo...

"ISRO has capabilities to build geostationary satellites for air quality monitoring” (downtoearth)

Pawan Gupta's findings on trans-boundary movement of pollution (Punjab to Delhi) from biomass burning in 2015 spurred debates. He participated in discussions with Indian regulators early September at the Better Air Quality Conference in Busan on the advantages of using satellite data for air quality monitoring. He explains to Down to Earth how air quality monitoring is done using satellite data. How is satellite data used to measure air pollution? Satellites that provide information on atmospheric pollutants are normally (not always) in the low earth orbits (400-1000 km above the Earth’s surface). A single satellite can carry one or more remote sensing instruments onboard that look down to earth and obtain information about the object in the field of view of satellite sensor. The Earth receives electromagnetic radiation from the sun, which travels through space and reaches the earth-atmosphere system. The radiation then interacts with the Earth’s atmosphere and the surface...
