Gut Microbiomes of Infants Have an Impact on Autoimmunity
April 29th 2016Exposure to pathogens early in life is beneficial to the education and development of the human immune system. Over the past few decades, the healthcare community has observed an intriguing phenomenon: diseases related to the immune system -- type 1 diabetes, and other autoimmune diseases, allergies, and the like -- have taken hold in countries that have thriving, modern economies, while barely making a mark in the developing world. One of the best-supported theories to explain this peculiar public health pattern has been dubbed the hygiene hypothesis. The theory is based on the premise that exposure to pathogens early in life is actually beneficial to the education and development of the human immune system.
Scientists Reveal the Secret of Antibiotic-Resistant Bacteria
April 28th 2016Researchers from the Scientific Research Institute of Physical-Chemical Medicine, MIPT, the company M&S Decisions and the research department of Yandex have built a computer model of the interaction between different bacteria, and between bacteria and the gut wall. This has led them to explain how antibiotic-resistant microbes develop and spread; details of the study have been published in the journal PLOS ONE.
Nanoparticles Hold Promise as Double-Edged Sword Against Genital Herpes
April 27th 2016An effective vaccine against the virus that causes genital herpes has evaded researchers for decades. But now, researchers from the University of Illinois at Chicago working with scientists from Germany have shown that zinc-oxide nanoparticles shaped like jacks can prevent the virus from entering cells, and help natural immunity to develop.
Scientists Develop Faster, More Effective Detector of Fungal Infections
April 27th 2016Fungal infections are a serious problem in modern healthcare. A critical factor in their successful treatment is time: the faster they are detected, the more effectively dangerous infections can be prevented. At the Institute of Physical Chemistry of the Polish Academy of Sciences in Warsaw a chemical sensor has been devised enabling the detection time of fungi to be shortened from the current couple of days to just a few minutes.
Titanium Dioxide Exposure Increases Risk of Bacterial Infection
April 27th 2016When human cells are exposed to titanium dioxide without the presence of UV light from the sun, the risk for bacterial infection more than doubles. This finding by a Stony Brook University-led research team, published early online in the Journal of Nanobiotechnology, raises concerns about exposure to titanium dioxide, a nanoparticle commonly used in millions of products worldwide ranging from cosmetics to toothpaste, gum, food coloring and medicines.
Scientists Find the Potential Target for the Revolutionary Antibiotics
April 25th 2016An international team of including the Lomonosov Moscow State University researchers discovered which enzyme enables Escherichia coli bacterium (E. coli) to breathe. The study is published in the Scientific Reports.
