Stanford researchers make hair-cell-like cells in a petri dish

Deep inside the ear, specialized cells called hair cells detect vibrations in the air and translate them into sound. Ten years ago, Stefan Heller, PhD, professor of otolaryngology at the Stanford University School of Medicine, came up with the idea that if you could create these cells in the laboratory from stem cells, it would go a long way toward helping scientists understand the molecular basis of hearing in order to develop better treatments for deafness.

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.

Neurons' complicated tree-like structure formation unravelled

A breakthrough about the formation and maintenance of tree-like nerve cell structures could have future applications in the treatment of neurodegenerative diseases and the repair of injuries in which neurons are damaged. The findings by the international team led by Prof. Benjamin Podbilewicz of the Technion-Israel Institute of Technology Faculty of Biology are published in the May 6th issue of Science Express.

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.

YM BioSciences: Two posters on nimotuzumab accepted for presentation at AACR

YM BioSciences Inc., today announced that two posters have been accepted for presentation at the American Association for Cancer Research (AACR) Annual Meeting to be held from April 17-21 in Washington, DC. The first poster describes the results of the previously reported collaboration with researchers at the University of Toronto for the development of highly potent antibody-radionuclide conjugates for use in the treatment of cancer. The poster will describe activity of 111In-NLS-nimotuzumab against breast cancer cells with high and low EGFR expression.

Study sheds light on how CL-HA stimulates collagen repair in skin

In the U.S. and around the world, the popularity of minimally invasive cosmetic procedures continues to increase. Soft tissue injectables, also known as dermal fillers, are popular procedures that improve the appearance of aging and sun-damaged skin by restoring lost volume and filling lines.

ASPEX to display game-changing PSEM eXpress analyzer at Pittcon 2010

ASPEX Corporation has been advancing the novel Personal Scanning Electron Microscope (PSEM) platform since its first product generation was released in 1992. Since then, it has been "shifting" where SEMs are traditionally installed, "shifting" when SEMs are utilized in industrial processes, and fundamentally "shifting" how SEMs are identified. Come experience the shift at Pittcon 2010, in Orlando, FL from March 1-4.

Agilent Technologies launches industry’s first transportable GC/MS system delivering laboratory-quality analysis

Agilent Technologies Inc. today introduced the 5975T Low Thermal Mass (LTM) Gas Chromatography/Mass Spectrometry Detector (GC/MSD), the industry’s first commercial transportable GC/MS system that delivers laboratory-quality analysis. Using proprietary LTM technology, Agilent has developed the 5975T LTM GC/MS to be smaller, more rugged and to consume less power than in-lab GC/MS instruments, yet capable of the same high-quality performance in the field.

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.
