Nature has published a Chinese-led research on the relation between alterations of human gut bacteria and liver cirrhosis, the research team said on Friday. The research concluded that the alterations of gut microbiota dysbiosis can worsen the liver cirrhosis process. The scientists compared 98 patients and 83 healthy individuals. The researchers found that patients with liver cirrhosis have considerably lessRead more

Iranian researchers from Nanobiotechnology Department of the University of Tehran designed a nanosensor that has the highest reported value of sensitivity in the diagnosis of cancer. The nanosensor enables diagnosis of cancer in its early stages through a fast, simple and cheap method. The presence of DNA chains caused by cellular death in blood is a very good opportunity toRead more

Researchers have used an anti-tank Javelin missile detector, more commonly used in warfare to detect the enemy, in a new test to rapidly identify malaria parasites in blood. The technique is based on Fourier Transform Infrared (FITR) spectroscopy, which provides information on how molecules vibrate. State-of-the-art military hardware could soon fight malaria, one of the most deadly diseases on theRead more

A vaccine for dust-mite allergies has been created, researchers report. In lab tests and animal trials, the nano-sized vaccine package was readily absorbed by immune cells and dramatically lowered allergic responses. If you're allergic to dust mites (and chances are you are), help may be on the way. Researchers at the University of Iowa have developed a vaccine that canRead more

83 new genes which could help identify schizophrenia earlier and more effectively have been found in a global study in which researchers from the Institute of Mental Health (IMH) and Genome Institute of Singapore (GIS) have participated, local media reported on Tuesday. Researchers looked at over 80,000 genetic samples from individuals with and without schizophrenia, and found 108 specific markerRead more

Results of an international study show a new combination of drugs means that drug-resistant tuberculosis (TB) can be cured in as little as four months, instead of two years, local media reported on Monday. The drug combination, known as PaMZ, killed more bacteria than standard treatment and was effective in treating drug-resistant TB, the Australian Broadcasting Commission (ABC) reported. "ThisRead more

Scientists designed a new self-assembling nanoparticle that targets tumours, to help doctors diagnose cancer earlier. The new nanoparticle, developed by researchers at Imperial College London, boosts the effectiveness of Magnetic Resonance Imaging (MRI) scanning by specifically seeking out receptors that are found in cancerous cells. The nanoparticle is coated with a special protein, which looks for specific signals given offRead more

Iranian researchers from Tarbiat Modarres University changed the liposome production process and increased the amount of genes entrapped in the structure of these nanocarriers. The non-virus nanocarriers have neutral structure and very high stability and they protect entrapped genes against degrading enzymes. In this research, some changes were made in the synthesis of liposomes and nanocarriers were produced that canRead more

In what parts of the world and to what degree have groundwater reservoirs been depleted over the past 50 years? Scientists have been researching this using the global water model WaterGAP. The Frankfurt hydrologist Prof. Petra Döll has been researching this using the global water model WaterGAP. She has arrived at the most reliable estimate to date by taking intoRead more

An international team of researchers found new evidence that our prehistoric ancestors had a detailed understanding of plants long before the development of agriculture. By extracting chemical compounds and microfossils from dental calculus (calcified dental plaque) from ancient teeth, the researchers were able to provide an entirely new perspective on our ancestors' diets. Their research suggests that purple nut sedgeRead more
