New tool reveals secrets of migrating cells

...o see in four-dimensions - in 3-D in real time. It opens an entirely different universe to us," Witt said. Images and videos : Antigen-Engaged B Cells Undergo Chemotaxis toward the T Zone and Form Motile Conjugates with Helper T Cells Directed Migration of Positively Selected Thymocytes Visualized in...

Breakthrough: Scientists create world's tiniest organic particles

...thod, which is really exciting, for the first time opens the world's door to marrying organic materials to nanotechnology. Biology, after all, is almost exclusively organic materials."We really believe this work will have a profound positive impact down the road on human health care. This includes, but is ...

Major breakthrough in the treatment of cancers and infectious diseases

... this light, the discovery of Dr. Veillette's team opens new avenues for the treatment of cancers and communicable diseases. ...

Achilles heel of the herpes virus possibly found

...or that appears to function as one "lock" that HSV opens to allow it to enter human cells. They've also found the gene that controls the production of that receptor, deciphered some aspects of the receptor's structure, and developed a pig-cell system that could be used to test new anti-herpes drugs. The f...

Unusual antibiotics show promise against deadly 'superbugs'

...aps formed by loose collagen strands. This linkup opens the door to new medical treatments, Yu says, because it is easy to attach bioactive agents to the peptides. When the peptides bind with collagen, these attached agents can dramatically change the way collagen behaves in the body. For example, collage...

Modified collagen could yield important medical applications

Researchers reveal secret of key protein in brain and heart function

...problem," Mierke said. "Solving protein structures opens doors for effective treatments." SAP97 is found mainly in the central nervous system and is known as a "scaffolding" protein. In this role, it serves as a sort of tether, grabbing proteins inside the cell critical to nerve signaling and keeping them...

Tamoxifen-like drug suggests new ways to selectively block estrogen

...ns, such as breast, bone or uterus." This finding opens a new arena for drug design, suggests Greene. Nuclear receptors, such as the estrogen receptor, are major drug targets, accounting for more than 20 percent of all drugs. This finding suggests "we could move beyond 'designer estrogens,' to all sorts o...

Evidence of 600-million-year old fungi-algae symbiosis discovered in marine fossils

...ious fungi," Xiao said. "The Doushantuo Formation opens a window into ancient marine life. There is a lot more remains to be learned from these rocks," Yuan added. ...

Scientists use manufacturing methods to reconstruct mastodon

Meanwhile, museum visitors can peek through special viewing windows to watch preparators assemble the skeleton, which will bear 7-foot tusks. The specimen, named the Buesching mastodon for the Indiana family on whose property i...

While on trail of dioxin, scientists pinpoint cancer target of green tea

...?they simply take an aspirin –the current research opens the door to extending the health benefits first discovered in green tea to people who never touch the beverage. Isolating the chemicals that protect against cancer would also sidestep questions such as how to take into account different types of teas...

Master gene controls healing of skin in fruit flies and mammals

Supercomputers to focus brains on AIDS dilemma

..., 2004. These simulations revealed that a "trench" opens intermittently in the area of the integrase catalytic site, suggesting that it should be possible to develop inhibitors that bind with their cyclic moieties to the "east" of the active center as well as to the "west." Based on these simulations, the ...

NYU and MSKCC research provides model for understanding chemically induced cancer initiation

...cinogens." The researchers added that the finding opens new horizons, at the molecular level, for understanding the effects of methylation at p53 mutation hot spots on the properties of carcinogen-DNA lesions. Current thinking in the field of chemical carcinogenesis is that the mutation-prone, or error-fr...

Protein helps regulate the genes of embryonic stem cells

...d is required to modify histone H3 in a unique way opens up new lines of investigation into the role eed might play in diverse biological processes. "It may give us new gene targets to study relative to cancer and other disease states that may have these marks and have not been examined but should be," Ma...

Robot-based system developed at Carnegie Mellon detects life in Chile's Atacama desert

...h high intensity flashes of light. The camera only opens during those flashes, so we are able to capture a strong fluorescence signal during daytime exploration," said Shmuel Weinstein, project manager. During the mission, a remote science team located in Pittsburgh instructed the rover's operations. A gr...

Asthma gene clusters identified

... Children's Hospital Medical Center. The discovery opens the door to the possibility of designing treatments specifically tailored to children who suffer from the severest forms of asthma. The findings appear in the Feb. 10 issue of the Journal of Allergy and Clinical Immunology. The study is based on an...

Rush Physicians Using Gene Therapy For Heart Patients With Moderate To Severe Chest Pains Who Do Not Benefit From Other Treatments

... a catheterization with a balloon-like device that opens blocked arteries, while bypass surgery requires open-heart surgery to place veins removed from the patient's leg or arteries taken from the patient's chest wall or arm to "bypass" the blocked blood vessels. While both of these treatments have been s...

Unexpressed But Indispensable -- The DNA Sequences That Control Development

...overy of these developmentally important sequences opens several avenues of new research. For example, analyzing the sequence and location of these CNEs may help point the way to other non-coding elements that remain undiscovered. It is also likely that mutations in these critical sequences cause human dis...
