Researchers create tissue-engineered small intestine in mice

Researchers at The Saban Research Institute of Children's Hospital Los Angeles have successfully created a tissue-engineered small intestine in mice that replicates the intestinal structures of natural intestine-a necessary first step toward someday applying this regenerative medicine technique to humans.

Neurochemical-producing probiotics can promote healthy gut and mind

Probiotics, often referred to as 'good bacteria', are known to promote a healthy gut, but can they promote a healthy mind? Exploring the new world of neurological probiotics, researchers in BioEssays present new ideas on how neurochemicals delivered directly to the gut, via probiotic intestinal microbiota, exert their beneficial effects in maintaining gastrointestinal health and even psychological well-being.

Periodontal disease can affect woman's chance of conceiving

Professor Roger Hart told the annual meeting of the European Society of Human Reproduction and Embryology that the negative effect of gum disease on conception was of the same order of magnitude as the effect of obesity.

Patients with ESBL-producing bacteria need better health care

Fear and confusion surrounding the diagnosis is often the result of suffering of antibiotic-resistant bacteria. Accurate information is crucial for these patients in order for them to handle their situation, yet that is the area where health care is lacking.

Researchers use clever technique to look at in vivo virus-bacterium interactions

Viruses are the most abundant parasites on Earth. Well known viruses, such as the flu virus, attack human hosts, while viruses such as the tobacco mosaic virus infect plant hosts.

Antimicrobial copper surfaces reduce risk of acquiring hospital infection

Professor Bill Keevil, Head of the Microbiology Group and Director of the Environmental Healthcare Unit at the University of Southampton, has presented research into the mechanism by which copper exerts its antimicrobial effect on antibiotic-resistant organisms at the World Health Organization's first International Conference on Prevention and Infection Control.

Early infection with H. pylori protects against allergy-induced asthma

Infection with the gastric bacterium Helicobacter pylori provides reliable protection against allergy-induced asthma, immunologists from the University of Zurich have demonstrated in an animal model together with allergy specialists from the University Medical Center of the Johannes Gutenberg University Mainz.

New book explores research into viral nanoparticles

Viruses that attack plants, insects, mammals and bacteria are proving effective platforms for delivering medicines and imaging chemicals to specific cells in the body, as building blocks for tiny battery electrodes and computer data storage devices, and other nanotechnologies.

New technique can remove oil spill from soil

It is well known just how damaging oil can be to nature. It is also well known just how difficult it can be to clean up after a spill or contamination. Removing an oil spill or contamination from soil is hard and requires very different techniques to removing oil from water.

Recombinant attenuated Salmonella vaccines hold promise against infectious diseases

A powerful new class of therapeutics, known as recombinant attenuated Salmonella vaccines (RASV), holds great potential in the fight against fatal diseases including hepatitis B, tuberculosis, cholera, typhoid fever, AIDS and pneumonia.

UNC study uses optogenetics to tweak brain wiring responsible for drug addiction behaviors

Using a combination of genetic engineering and laser technology, researchers at the University of North Carolina at Chapel Hill have manipulated brain wiring responsible for reward-seeking behaviors, such as drug addiction.

S. aureus pneumonia rates in children have doubled over past decade

The rate of pneumonia in children caused by infection with Staphylococcus aureus bacteria has doubled over the past decade, according to a paper in the July issue of The Pediatric Infectious Disease Journal. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health.

Rapid, accurate test differentiates between bacterial and viral infections

Scientists are reporting development and successful testing of a rapid and accurate test to tell the difference between bacterial and viral infections. Those common afflictions often have similar symptoms but vastly different treatments - antibiotics work for bacterial infections but not for viruses. The report appears in ACS' journal Analytical Chemistry.

Vaccines may be given in food in the near future

Soon children could be vaccinated with bacteria mixed in milk and people in the developing world given unprecedented access to immunisations under a scheme proposed by an Australian Nobel laureate, Barry Marshall.

Inefficiency of activation-induced deoxycytidine deaminase is good for the immune system

Why is antibody diversity important? Think about it like this, said Myron Goodman, who is an author on the paper: "Why don't you die when I sneeze? It's because you have a powerful immune system. And the way to get a decent immune system is for your body to have a way to respond to insults it has never seen before."
