Scientists identify molecular structure of key viral protein

...ruses. Knowing the structure of the F protein will aid understanding of all members of the paramyxovirus family, which are among the most significant human and animal pathogens, causing both respiratory and systemic disease. "The development of antiviral drugs is helped by knowledge of the structure, s...

Worm hormone discovery may aid fight against parasitic disease

... suspended. The UT Southwestern research also may aid in the fight against human disease because the dauer diapause stage of C. elegans is very similar to the infective state of parasitic nematodes. According to the World Health Organization, such parasites infect about 2 billion people worldwide and se...

New test to detect rare proteins in blood

...rgets from much smaller sample volumes, as well as aid in monitoring marker levels at much earlier stages of disease. "The importance of FACTT is that we can still get an accurate description of the number of molecules that cause disease even when other assays cannot," says Greene. The researchers surm...

High-resolution light microscope reveals the fundamental mechanisms of nerve communication

...patch whichpreviously formed the vesicle. With the aid of STED microscopy the researchers in Göttingen were able to show that the synaptotagmin molecules of a single vesicle remain together after fusion. The membrane ofthe nerve cell thus behaves in an 'economical' fashion: the vesicle proteins released ...

Georgia Tech accelerates drug discovery with new IBM supercomputing cluster

...l processes of human cancer genes and proteins, to aid in the development of more targeted drugs to treat such diseases. "Universities today are looking for the fastest, most innovative and cost-efficient systems to help their intellectual communities translate the research they generate into viable inf...

Penguins waddle but they don't fall down, UH researchers say

...r walking patterns," Kurz said. "This research may aid in developing a way to teach those people how to walk more efficiently despite their side-to-side motion, to learn the same kind of stability as the penguin." Another application for this research involves the construction of sophisticated robots....

Scientists discover basic defect in cystic fibrosis airway glands

... The first is that the defective CFTR is unable to aid in fluid secretion in cystic fibrosis airway glands. The second explanation is that the glands still secrete fluid via non-CFTR pathways, but the fluid is reabsorbed by other channels. In fact, it has been proposed that one of CFTR's functions is t...

Earth Rx: A microbial biotechnology prescription for global environmental health

... the real world, where it isn't so luxurious." To aid in the identification and function of individual microorganisms and communities, the first use of modern molecular biology tools began in the early 1980s, with the advent of polymerase chain reaction (PCR) amplification of microbial DNA and a new vie...

Stem cell study for patients with heart attack damage seeks to regenerate heart muscle

...flammatory signals to various areas of the body to aid in repair. The delivered cells are expected to respond to the body's own signals and migrate to the area of injury. The Phase I study is double blind; two thirds of the participants receive the stem cells and one-third receive a placebo. To be eligi...

Study suggests that publicly available genome data may contain small but significant errors

...marks can be used to assemble physical maps, as an aid to sequence assembly, or as an independent method for validating sequence assembly and indicating where errors need correction. Comparing data from their inferred probe maps to the available sequence assembly, the new method provides insights in...

Powerful technique for multiplying adult stem cells may aid therapies

...e patients." But most importantly, these findings aid basic research. "We want to know all sorts of things, like what genes are active in this stem cell, or how this stem cell decides to develop into one kind of cell as opposed to another," says Lodish. Lodish and his colleagues are collaborating wit...

'Executive' monkeys influenced by other executives, not subordinates

...utism, he noted. Also, he said, such studies could aid understanding a wide range of disorders such as social anxiety. More broadly, said Shepherd, such studies in monkeys will enable greater insight into the basic machinery of social interaction. "Thanks to a combination of molecular and behavioral st...

Cell therapy slows progression of an inherited neurological disease; Improves motor skills in mice

...lly moved to regions of the brain where they could aid in producing myelin. The transplanted cells also helped lead to production of healthy myelin and improved motor coordination. "There is much excitement in the field of cell-based therapy and this study is a clear indication of its potential," says M...

Terahertz imaging may reduce breast cancer surgeries

...d, in conducting the study. "This technology could aid the surgeon in immediately identifying residual cancer after the main tumor has been removed, thus minimizing the need for additional surgical procedures." Currently, excised tissue samples must be sent for histopathologic examination, which typical...

Mining for gems in the fungal genome

...e primary metabolites are essential compounds that aid basic growth and reproduction in fungi, secondary metabolites are not required for life. "Secondary metabolites are bioactive compounds that are only produced at select times during the life cycle of the organism," explains Keller, noting that the c...

...de readers to the designated links. Another study aid is the BrainX E-Learning System study guide. Purchase of Microbe includes access to this powerful online study guide that enhances learning and allows students to make more productive use of their study time. Microbe has a list price of $89.95 ...

Pair of studies offer new clues to combat antibiotic resistance

...the gram-positive bacterial membrane is formed and aid in the design of new antibiotics to block its formation, says Walker. Her lab will soon begin screening for compounds that can block this important chemical pathway, she says. Gram-positive bacteria include anthrax and other strains that cause upper...

ASU researchers 'wire' DNA to identify mutations

...ese subtle DNA differences among the populace will aid the ongoing quest to understand and prevent disease. "There is a high demand to track mutations for cancer research or future applications in personalized medicine," said Zhang, an associate research professor of the Center for Single Molecule Biop...
