OHSU research shows vitamin C counteracts some negative impacts of smoking on unborn babies
Research conducted in monkeys at the Oregon National Primate Research Center, Oregon Health & Science University, suggests high doses of vitamin C may have potential to counteract some negative impacts of smoking in unborn babies. The research may benefit thousands of babies born to mothers who continue to smoke throughout pregnancy despite physician warnings. The research is published in the...Bacteria recognize antimicrobials, respond with counter-defenses
Many living things, from fruit flies to people, naturally produce disease-fighting chemicals, called antimicrobial peptides, to kill harmful bacteria. In a counter move, some disease-causing bacteria have evolved antimicrobial detectors. The bacteria sense the presence of antimicrobial peptides as a warning signal. This alarm sets off a reaction inside the bacteria to avoid destruction. Un...Plant defenses prompt bacterial countermeasure in the form of 'island' DNA excision
Seeking to catch an arms-race maneuver in action, researchers have uncovered new evidence to explain how bacteria in the process of infecting a plant can shift molecular gears by excising specific genes from its genome to overcome the host plant's specific defenses. Throughout evolution ?in the wild and in crops cultivated by humans ?plants have developed systems for resisting the attack o...Anthrax inhibitor counteracts toxin, may lead to new therapeutics
Researchers from Rensselaer Polytechnic Institute and the University of Toronto have designed a nanoscale assembly of molecules that successfully counteracts and inhibits anthrax toxin in animal and laboratory experiments. The novel approach used to neutralize anthrax toxin could be applied in designing potent therapeutics for a variety of pathogens and toxins, according to the researchers. <...Scientists re-engineer a well-known antibiotic to counter drug resistance
The scientists replaced a single atom from the molecular structure of vancomycin aglycon, a glycopeptide antibiotic that attacks the bacteria by inhibiting cell wall synthesis, significantly increasing the drug's spectrum of activity. In recent years, a number of the most common strains of enterococci have become resistant to vancomycin and use of the antibiotic has been under scrutiny. This re-e...Counting Non-Aqueous Samples in the TopCount Microplate Scintillation and Luminescence Counter
The microplate format has become a standard for many biological assays such as high throughput screening for drug discovery and radioimmunoassays. Productivity with these high volume procedures has been limited by the amount of sample handling required and low sample counting throughput. Now, however, microplate assays can be efficiently count...Polymer Degradation Mechanisms Encountered in Pyrolysis-GC/MS

Certain over-the-counter pain relievers commonly used to counter the pain and inflammation of rheumatoid arthritis also may cut the risk of getting Alzheimer's disease. In addition to their anti-inflammatory properties, the drugs seem to selectively reduce levels of a harmful protein linked to the neurodegenerative disease. The study developed from research suggesting that people taking certain N...Ways to counter radiation effects with new molecule discovery
Radiation inflicts serious damage to the DNA within our cells, which could lead to cancer. However, researchers have now found a molecule that triggers a protective mechanism in the body, which both repairs the damage and induces severely damaged cells to destroy themselves. The molecule called MDC1, which initiates this protection mechanism, was discovered by researchers at the Institute of Canc...Drug In Asthma inhaler Found To Counteract Benefits
Researcher say recent findings may explain why some patients who use the inhalers actually get worse over time.The ingredient is albuterol, in a class of medications called beta-agonists. In inhalers it is combined with steroids // to open airways and ease the gasping of patients with asthma and other lung diseases. Albuterol has two forms or isomers -- a so-called left-handed version and a right...The Counter Effect Of Alzheimer's Drug
Quetiapine, a drug used to treat agitation in patients with Alzheimer's or dementia, may actually worsen cognitive decline say researchers based on findings of a recent study .// For the study 80 nursing home patients were observed . Twenty-six of the patients received quetiapine (an antipsychotic also known as Seroquel), 25 received rivastigmine (a cholinesterase inhibitor also known a...The Use of Radio Frequency Identification ( RFID) to tackle the growing menace of counterfeit drugs
Manufacturers across the world have been constantly coming up with new strategies// and technologies to curb the proliferation of counterfeit drugs in the market. Deputy director BK Karna of Indian Institute of Packaging says although pharma companies are trying to bring in novel features to prevent proliferation of duplicated drugs with new package designs such as child resistant closu...Quebec Darkfield Colony Counter, 110V with USA Cord
