  1. Many Hospitals are too Liberal with Antibiotics

    Doctors in many U.S. hospitals are unnecessarily prescribing multiple antibiotics for several days when just one would do the job, a new study released this week suggests.

    Health officials have sounded alarms that overuse of antibiotics is helping to breed dangerous bacteria that are increasingly resistant to treatment. Much of the attention has been on doctor offices that wrongly prescribe bacteria-targeting antibiotics for illnesses caused by viruses.

    The new study focuses on a different issue — when hospital doctors throw more than one antibiotic at a mystery infection.

  3. Method Enables Portable Detection of ‘Bath Salts’Despite being outlawed in 2012 in the U.S., the synthetic drugs known as “bath salts” — which really aren’t meant for your daily bath — are still readily available in some retail shops, on the Internet and on the streets. To help law enforcement, scientists are developing a novel method that could be the basis for the first portable, on-site testing device for identifying the drugs. They report their advance in the ACS journal Analytical Chemistry.Craig Banks, in collaboration with Oliver Sutcliffe at Manchester Metropolitan Univ., notes that the high-inducing substances in bath salts, which are synthetic cathinones that also go by “plant food,” “glass cleaner” and a number of other innocuous-sounding names, are derived from a stimulant in a plant called khat. The plant is found on the Arabian Peninsula and East Africa.Read more: http://www.laboratoryequipment.com/news/2014/09/method-enables-portable-detection-%E2%80%98bath-salts%E2%80%99

  5. Study of Cannabis Paves Way for New DrugsA revolutionary nanotechnology method could help improve the development of new medicine and reduce costs. Researchers from the Nano-Science Center and the Department of Chemistry at the Univ. of Copenhagen have developed a new screening method that makes it possible to study cell membrane proteins that bind drugs, such as cannabis and adrenaline, while reducing the consumption of precious samples by a billion times.About 40 percent of all medicines used today work through the so-called “G protein-coupled receptors.” These receptors react to changes in the cell environment, for example, to increased amounts of chemicals like cannabis, adrenaline or the medications we take and are therefore of paramount importance to the pharmaceutical industry.Read more: http://www.laboratoryequipment.com/news/2014/09/study-cannabis-paves-way-new-drugs

They found that while most of the compounds were likely to cause only a low risk to aquatic life, ibuprofen might be having an adverse effect in nearly 50 percent of the stretches of river studied.In what is believed to be the first study to establish the level of risk posed by ibuprofen at the country scale, the researchers examined 3,112 stretches of river that together receive inputs from 21 million people.Read more: http://www.laboratoryequipment.com/news/2014/08/ibuprofen-may-pose-threat-fish

  11. Pomegranate Drug May Stem Alzheimer’s, Parkinson’sThe onset of Alzheimer’s disease can be slowed and some of its symptoms curbed by a natural compound that is found in pomegranate. Also, the painful inflammation that accompanies illnesses such as rheumatoid arthritis and Parkinson’s disease could be reduced, according to the findings of a two-year project headed by Univ. of Huddersfield scientist Olumayokun Olajide, who specializes in the anti-inflammatory properties of natural products.Now, a new phase of research can explore the development of drugs that will stem the development of dementias such as Alzheimer’s, which affects some 800,000 people in the UK, with 163,000 new cases a year being diagnosed. Globally, there are at least 44.4 million dementia sufferers, with the numbers expected to soar.Read more: http://www.laboratoryequipment.com/news/2014/08/pomegranate-drug-may-stem-alzheimer%E2%80%99s-parkinson%E2%80%99s

  13. Laser Tweezers Reveal How Malaria Infects Blood CellsMalaria is a life-threatening disease caused by a parasite that invades one red blood cell after another. Little is known about this infection process because it happens so quickly, potentially explaining why there is currently no approved malaria vaccine. In a study published by Cell Press August 19th in the Biophysical Journal, researchers used a tool called laser optical tweezers to study interactions between the disease-causing parasite and red blood cells. The findings reveal surprising new insights into malaria biology and pave the way for the development of more effective drugs or vaccines for a disease that affects hundreds of millions of people around the world.Read more: http://www.laboratoryequipment.com/news/2014/08/laser-tweezers-reveal-how-malaria-infects-blood-cells

  25. Venoms Hold Potential to Fight Cancer

    Bee, snake or scorpion venom could form the basis of a new generation of cancer-fighting drugs, scientists say. They have devised a method for targeting venom proteins specifically to malignant cells while sparing healthy ones, which reduces or eliminates side effects that the toxins would otherwise cause.

    The report was part of the 248th National Meeting of the American Chemical Society (ACS). “We have safely used venom toxins in tiny nanometer-sized particles to treat breast cancer and melanoma cells in the laboratory,” says Dipanjan Pan, from the Univ. of Illinois, who led the study. “These particles, which are camouflaged from the immune system, take the toxin directly to the cancer cells, sparing normal tissue.”

Researchers have identified a compound, hydroxynorketamine (HNK), which may treat symptoms of depression just as effectively and rapidly as ketamine, without the unwanted side effects associated with the psychoactive drug, according to a study in the July issue of Anesthesiology, the official medical journal of the American Society of Anesthesiologists (ASA).
