New findings on protein factories could unravel cell complexities, lead to new antibiotics and disease treatments

A team from The Scripps Research Institute has revealed the first-ever pictures of the formation of cells' "protein factories." In addition to being a major technical feat on its own, the work could open new pathways for development of antibiotics and treatments for diseases tied to errors in ribosome formation. In addition, the techniques developed in the study can now be applied to other complex challenges in the understanding of cellular processes.

NHGRI announces fund to develop third generation DNA sequencing technologies

More than $18 million in grants to spur the development of a third generation of DNA sequencing technologies was announced today by the National Human Genome Research Institute (NHGRI). The new technologies will sequence a person's DNA quickly and cost-effectively so it routinely can be used by biomedical researchers and health care workers to improve the prevention, diagnosis and treatment of human disease.

Human endogenous retroviruses may provide insight evidence to HIV diagnosis

Why is it so hard to isolate and purify human immunodeficiency virus (HIV).Why has no one been able to see, by electron microscopy, a single HIV particle in the blood of AIDS patients, even those who have a "high viral load" Why does HIV seem to mutate with startling rapidity. AIDS researchers have not been able to come up with answers to these questions.

Researchers clear hurdle on path toward gene-therapy treatment for disease

One of the most difficult aspects of working at the nanoscale is actually seeing the object being worked on. Biological structures like viruses, which are smaller than the wavelength of light, are invisible to standard optical microscopes and difficult to capture in their native form with other imaging techniques.

Researchers develop high-resolution technology to visualize individual virus particles

In the war against infectious disease, identifying the culprit is half the battle. Now, research professor Shaopeng Wang and his colleagues from the Biodesign Institute at Arizona State University, describe a new method for visualizing individual virus particles. Their research opens the door to a more detailed understanding of these minute pathogens, and may further the study of a broad range of micro- and nanoscale phenomena.

Rutgers researchers report genetic coding responsible for making QPM kernels sturdy

Rutgers researchers have discovered the basis for what makes corn kernels hard, a quality that allows corn to be easily harvested, stored and transported. The findings could lead to better hybrids and increase the supply for people in developing countries who rely on it as a nutritional staple.

Pelvic extraperitoneal IMT with malignant transformation in 14-year-old

Inflammatory myofibroblastic tumor (IMT) is an uncommon benign neoplasm with locally aggressive behavior but malignant change is rare. Such a rare tumor occurring in a 14-year-old patient with clinical presentations of abdominal pain and body weight loss was seldom described before.

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.

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.
