Current interest in probiotics is motivated not only by the clinical data showing the efficacy of some probiotic bacteria, but also by the increasing antibiotic resistance of pathogenic bacteria (particularly in hospitals) and the rise of consumers demand for natural substitutes of drugs.
Among probiotic applications, reduction of diarrhea is probably the best-documented effect confirmed by recent meta-analyses. Research on Helicobacter pylori indicates that probiotics are unable to eradicate the infection, but could be useful in decreasing infection levels and as adjuvants of therapy-associated side effects. Studies performed in inflammatory bowel disease suggest that high doses of probiotics and most likely a combination of different lactobacilli and bifidobacteria are more effective in decreasing inflammatory score and maintaining patients in remission than a single probiotic strain. Probiotic studies evaluating amelioration of symptoms in irritable bowel syndrome would require more sustained patient numbers, but the efficacy seems to be strain-dependent. Not enough probiotic intervention trials have been reported on colon cancer to allow any firm conclusion.
Few randomized, double-blind placebo-controlled human trials are available, and some involved only small numbers of patients. They are difficult to compare because of the differences in probiotic strains employed, doses and formulation. However, the accumulated data is encouraging.

Scientists have developed a new method of characterizing graphene’s properties without applying disruptive electrical contacts, allowing them to investigate both the resistance and quantum capacitance of graphene and other two-dimensional materials. Researchers from the Swiss Nanoscience Institute and the University of Basel’s Department of Physics reported their findings in the journal Physical Review Applied.
Graphene consists of a single layer of carbon atoms. It is transparent, harder than diamond and stronger than steel, yet flexible, and a significantly better...
The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.
The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...
Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
