Gene therapy converts dead bone graft to new, living tissue

... prospects of this technology," says Schwarz. "Our ultimate goal is to apply this to one of the Holy Grails of orthopedics ?cartilage repair. Unlike bone, damaged cartilage, even in a healthy person, can't re-grow or repair itself. "It's a steeper challenge that would require additional technology such as li...

In the sea slug's defense against lobsters, confusion is key

...nd a confused response that facilitates the slug's ultimate escape. The team of researchers conducting the study, Cynthia Kicklighter, Zeni Shabani, and Paul Johnson, led by Charles Derby of Georgia State University, discovered that in addition to containing unpalatable, aversive chemicals, Aplysia's inky se...

Scientists rid stem cell culture of key animal cells

...el means that contamination remains a concern. The ultimate goal, he says, would be to culture stem cells in media completely free of any animal products. ...

The Shapes Of Life: NIGMS Project Yields More Than 1,000 Protein Structures

...vell. The findings contribute to the initiative’s ultimate goal of providing structural information on 4,000-6,000 unique proteins that represent the variety found in organisms ranging from bacteria to humans. Researchers can use these structures, which are determined experimentally, to build computer models...

Tiny scaffolding allows stem cells to become working fat cells

...housands of patients nationally," Kniss said. "One ultimate goal of this work might be creating new tissue that could serve either as a temporary substitute while waiting for a donor organ, or even providing a replacement organ." Along with Xihai Kang and Yubing Xie, both postdoctoral fellows in his laborato...

Examination of internal 'wiring' of yeast, worm, and fly reveals conserved circuits

...ion." Systems biologists such as Ideker say their ultimate goal is a comprehensive computer model of how cells work. A description of all protein-interaction circuits would make such a model possible. "We'd like to simulate diseased cell types, such as cancer cells, and then simulate the effects of drugs on ...

Asthma gene clusters identified

...ector of the CMC and co-author of the study. "Our ultimate goal is to provide physicians the data they need to prescribe the most effective medications, discover new therapies and to help prevent disease," he said. Ultimately, Dr. Hershey's goal would be to identify gene profiles that are expressed during a...

Programmable cells: Engineer turns bacteria into living computers

... to study how small modifications would affect the ultimate behavior of the organisms. So far, said Weiss, the experimental results have matched the computer models fairly closely, but the goal is to have a mathematically exact description of how each component works. "One of the nice things about synthetic ...

Stem Cell Research Shows Potential for Replacing Tissue Damaged in Heart Attacks

...ese findings are applicable to human ES cells. The ultimate goal is to find out whether cardiac myocytes from ES cells can repair diseased or damaged adult myocardium in non-human models. This last question is being answered in collaboration with John Auchampach, Ph.D., associate professor of pharmacology &am...

Bioelectronic ‘signatures?hold key to DNA mutations

...monitors glucose levels through human sweat. “The ultimate goal is to make something similar to a hand-held glucose monitor for future genetic testing,?Wang says. “The electronic detection of DNA is a thing of beauty. You can make it small, low-power, inexpensive and robust.?/p> Among the keys to unearth...

Protein prevents detrimental immune effects of bacterial sepsis

... further investigating these immune pathways: "The ultimate goal is to use these new targets (e.g., a receptor for a given anti-inflammatory mediator) to develop better and safer drugs." The data for annexin 1 provide a new direction for such therapeutics that delicately balances removal of bacterial toxins a...

Currents could disrupt ocean food chain

...rate significant enough to prevent the sinking and ultimate mixing of the water. That would not only disrupt the Atlantic Conveyer current, Schmittner said, it would prevent nutrient-rich waters from triggering phytoplankton growth. "When the Atlantic Conveyer current works, the dead plankton sink to the bot...

UN pours polio vaccine into Yemen amid outbreak

...lobal eradication effort, they do not threaten its ultimate success," UNICEF said. The Global Polio Eradication Initiative, formed by WHO, UNICEF, Rotary International and the US Centers for Disease Control and Prevention, needed $50 million by July and $200 million for 2006, it added. UNICEF said polio has...

Newest HIV drugs should be used with FUZEON(R)

... with HIV. "Undetectable viral load should be the ultimate treatment goal for all triple-class experienced patients. FUZEON combined with the latest drugs now makes this much more achievable," explained Dr Mike Youle the Royal Free Hospital, London. "We are seeing a consistent FUZEON effect with these new dr...

Morphine for Chest Pain Increases Death Risk

... provides quarterly feedback to hospitals with the ultimate goal of improving adherence to the ACC/AHA treatment guidelines and patient outcomes. The CRUSADE registry is funded by Millennium Pharmaceuticals, Cambridge, Mass., and Schering Corp, Kenilworth, N.J. Bristol-Meyers Squibb/Sanofi Pharmaceuticals Pa...

Most common lung cancers may begin in newly discovered cells

...ous injury." The researchers acknowledge that the ultimate stem cell test remains. "One thing we have not done is taken BASCs and put them back into the mouse and show in vivo that they perform as stem cells," Bender Kim said. "We don't have an assay for that yet." With hematopoietic stem cells, for example...

Investigating 'brain shrinkage' in alcoholics

...e mechanisms underlying alcohol's damage, with the ultimate goal of identifying how to prevent and/or reverse these effects." Key presentation highlights were: - A number of toxic, metabolic, and nutritional factors interact in a complex way to cause brain damage in those individuals who abuse or are depend...

Brain size may depend upon how neural cells are cleaved

... point may play a powerful role in determining the ultimate size of the mammalian brain. Inherited disorders t...ted that the different division planes dictate the ultimate cell fate adoption of daughter cells," said Tsai. To determine definitively whether impairment of G...

Simple sea sponge helps scientists understand tissue rejection

...l-to-cell interactions, but is hard to study. The ultimate goal of this research is to provide insights into the machinery behind human tissue rejection and immune responses in hopes of someday being able to control these processes and save lives. ...

UF researchers kill resistant bugs one bandage at a time

...inical research and development. Developed as the ultimate wound dressing, the coating blocks bacteria from reaching a wound and recolonizing there. UF researchers and scientists from the company presented their findings at the Wound Healing Society's annual meeting earlier this year, and the coating's abili...
