Anti-infectives could circumvent the problem of antibiotic resistance

For a successful infection, bacteria must outwit the immune system of the host. To this aim, they deliver so-called virulence factors through a transport channel located in the bacterial membrane.

Research article focuses on how IECs respond to probiotic strain B. lactis HN019

Probiotics are a group of live microorganisms administered in adequate amounts which confer a beneficial health effect on the host. This bacterial community plays a pivotal role in human nutrition and health by promoting the supply of nutrients, preventing pathogen colonization and shaping and maintaining normal mucosal immunity.

NHLBI grants MU $8.47 million for research on cardiovascular diseases

One of the largest medical research grants ever awarded to the University of Missouri was announced today by MU scientists and administrators. The National Institutes of Health grant will help answer important questions about such prevalent health problems as high blood pressure, diabetes and stroke. The conditions are closely associated with cardiovascular disease, which is the leading cause of death in Missouri and the nation.

Cryo-EM images shed light on virus structure, function

UCLA researchers report in the April 30 edition of the journal Cell that they have imaged a virus structure at a resolution high enough to effectively "see" atoms, the first published instance of imaging biological complexes at such a resolution.

Artificial human skin with dermis made from fibrin-agarose biomaterial

Scientists from the University of Granada, Spain, have generated artificial human skin by tissular engineering basing on agarose-fibrin biomaterial. The artificial skin was grafted onto mice, and optimal development, maturation and functionality results were obtained. This pioneering finding will allow the clinical use of human skin and its use in many laboratory tests on biological tissues -which, additionally, would avoid the use of laboratory animals.

New methodology helps investigate unfolding of DNA

NYU Langone Medical Center researchers have developed a powerful new method to investigate the discrete steps necessary to turn on individual genes and examine how the process goes wrong in cancer and other diseases. The finding, based on seven years of research and described in the April 9 issue of Molecular Cell, allows scientists to investigate the unfolding of DNA, a process required for gene activation.

DIS serves as marker for new methods to diagnose NERD

Gastroesophageal reflux disease is an important public health problem which is extremely common nowadays. Symptoms of GERD arise from the exposure of increased acid gastric contents into the lower part of the esophageal mucosa. Most patients with GERD have NERD with invisible mucosal damages under endoscopy.

Caddisfly silk and sandcastle worm glue: Potential adhesives during surgery

Like silkworm moths, butterflies and spiders, caddisfly larvae spin silk, but they do so underwater instead on dry land. Now, University of Utah researchers have discovered why the fly's silk is sticky when wet and how that may make it valuable as an adhesive tape during surgery.

3D images of synapsis between neurons through electron cryotomography

A team of researchers from the Max Planck Institute of Biochemistry, in Germany, led by the Spanish physicist Rub-n Fern-ndez-Busnadiego, has managed to obtain 3D images of the vesicles and filaments involved in communication between neurons. The method is based on a novel technique in electron microscopy, which cools cells so quickly that their biological structures can be frozen while fully active.

Studies examine interaction of ribosome with molecular partners

Two new studies reveal in unprecedented detail how the ribosome interacts with other molecules to assemble new proteins and guide them toward their destination in biological cells. The studies used molecular dynamics flexible fitting (MDFF) to examine the interaction of the ribosome with two prominent molecular partners.
