Health News:Nano-walkers take speedy leap forward with first rolling DNA-based motor ♦ Antibody for severe hemophilia a may reduce injections needed to prevent bleeding

Nano-walkers take speedy leap forward with first rolling DNA-based motor A rolling DNA-based motor that's 1,000 times faster than any other synthetic DNA motor has been devised by physical chemists, giving it potential for real-world applications, such as disease diagnostics.

Patient deaths do not increase during doctor strikes As doctors in England prepare for strike action next month, researchers show that, in high-income countries, 'patients do not come to serious harm during industrial action provided that provisions are made for emergency care.

Clinical workstations: An overlooked reservoir for deadly bacteria? Clinical workstations within hospital intensive care units (ICUs) may get overlooked during routine cleanings and could therefore harbor more dangerous bacteria than regularly cleaned objects in patient areas.

Antibody for severe hemophilia a may reduce injections needed to prevent bleeding An antibody engineered to prevent excessive bleeding in patients with severe hemophilia A may be safe and effective, and require fewer injections than existing options.

Health News:Functional human liver cells grown in the lab ♦ Cataract surgery lessens patients' dizziness ♦ Scientists 'see' detailed makeup of deadly toxin for the first time

Functional human liver cells grown in the lab A new technique for growing human hepatocytes in the laboratory has now been described by a team of researchers. This groundbreaking development could help advance a variety of liver-related research and applications, from studying drug toxicity to creating bio-artificial liver support for patients awaiting transplantations.

Immune-disorder treatment in mice holds potential for multiple sclerosis patients A simple, rapid way to treat an immune-related disorder in mice has been identified by researchers, an approach that could eventually help multiple sclerosis patients after further research.

Cataract surgery lessens patients' dizziness Older people with visual impairment can report feeling dizzy and falling. A new study found that after routine cataract surgery, the improved vision led to patients experiencing significantly less dizziness, although they did not experience fewer falls.

Scientists 'see' detailed makeup of deadly toxin for the first time An exciting advance provides hope for developing novel potential method of treating pneumococcal diseases such as bacterial pneumonia, meningitis and septicaemia. A team of researchers uses a technique called X-ray crystallography to see the individual atoms of the toxin. World Health Organization (WHO) estimated that more than 1.6 million people every year die from pneumococcal infections, including more than 800,000 children under 5 years old.

4/26/14 Health News: Myths About Food Safety That Can Cost Your Life ♦ Who's Protecting Whom From Deadly Toxin? ♦ Sniffing Out Infection: Smell Test Speedier Than Urinalysis

Shocking Myths About Food Safety That Can Cost Your Life

There are 48 million new cases of foodborne illnesses every year in the United States. What's going on? Why are there so many cases of food poisoning each year? One cause is that people believe 'myths' about food poisoning that in reality hold no value Continue Reading

Who's Protecting Whom From Deadly Toxin?

Questions are swirling around a science journal's decision last year to publish a description of a newly discovered botulinum toxin while omitting key genetic details that researchers would normally disclose. The unusual case highlights important unresolved issues in how to balance scientific openness with the worry that biological information could potentially be misused. Continue Reading

Sniffing Out Infection: Smell Test Speedier Than Urinalysis

An "electronic nose" can sniff the difference between healthy urine specimens and those infected with Escherichia coli, according to a pilot study. "The electronic nose can identify not just the organism but the particular strain of organism. It has a specificity of almost 100%, which is very encouraging," said Emmanuel Johnson, MD, from the Royal Liverpool and Broadgreen University Hospital NHS Trust in the United Kingdom.

"We started with E coli because 80% of urinary tract infections in the community and 50% in hospitals are from E coli, but the potential is limitless," Dr. Johnson told Medscape Medical News. The results of the pilot study were presented here at the European Association of Urology (EAU) 29th Annual Congress. Continue Reading
