New designer lipid-like peptide with lipid nanostructures for drug delivery systems

...e peptides can be designed, just like to design an elegant watch, an art object, a music instrument, a ski, or a pair of sunglasses, we have the ultimate control to the outcome of the structure and their properties” Zhang added. This study stemmed from a scientific visit by Peter Laggner to Shuguang Zha...

An 'elegant' idea proves its worth 25 years later

... that. It was just astonishing," he says. "His elegant idea was to give patients chemicals they already make in small amounts in large doses to make up for the missing urea cycle enzyme they inherited," says Ada Hamosh, M.D., M.P.H, clinical director of the McKusick-Nathans Institute of Genetic Medicine....

Scientists unveil piece of HIV protein that may be key to AIDS vaccine development

...ue of Nature and is now available online. "This elegant work by Dr. Kwong and his colleagues provides us with a long-sought picture of the precise interaction between the HIV gp120 surface protein and this neutralizing antibody," says NIAID Director Anthony S. Fauci, M.D. "This finding could help in the d...

MIT device draws cells close -- but not too close -- together

...them around. This idea quickly evolved into an elegant tool designed expressly for biologists. The device involves two separate comb-shaped pieces coated with living cells. These two pieces can click into place at two settings: One allows cells on the edges of the combs to touch, the other maintains ...

Nobel Laureate finds 'elegant' explanation for DNA transcribing enzyme's high fidelity

...plished.? These findings offer “an unexpected and elegant explanation that’s both beautiful and simple, as nature invariably proves to be.? The fundamental mechanism of transcription is conserved among cellular RNA polymerases, the researchers explained. Common features include an unwound region of about 1...

Uncovering DNA's 'sweet' secret

DNA's simple and elegant structure - the "twisted ladder," with sugar-phosphate chains making up the "rails" and oxygen- and nitrogen-containing chemical "rungs" tenuously uniting the two halves - seems to be the work of an accomplished sculptor. Yet the graceful, sinuous ...

BC catalyst discovery promises faster, cheaper drug production

...well as the practical point of view." "This is an elegant solution to a very important, practical problem, with the potential to result in more efficient, more environmentally friendly, and less expensive processes for manufacturing drugs. It's a great example of how NIH support for fundamental chemical res...

Mouse study reveals new clues about virulence of 1918 influenza virus

...says NIH Director Elias A. Zerhouni, M.D. "This elegant research gives a detailed picture of the overzealous host reaction to infection by a fully reconstructed 1918 influenza virus," says NIAID Director Anthony S. Fauci, M.D. "The research provides clues as to why the flu of 1918 was so deadly, and may a...

Salk scientists get to the root of plant cell fate

...mustard plant Arabidopsis thaliana rather than the elegant rose recently determined why plants with a defective TOPLESS gene form an extra root where the shoot should be. Their findings, published in the June 9th issue of the journal Science, suggest that it is possible to engineer a plant cell to develop in...

The shape of life: research sheds light on how cells take shape

...eopards get spots. Every nautilus is encased in an elegant spiral shell. This phenomenon of pattern formation is critical in developmental biology. But the forces that govern it are far from clear. Alan Turing, father of modern computer science, suggested that the basis for pattern formation was chemical. ...

Researchers find 'secret weapon' used by SARS virus

...host gene expression, and then he designed several elegant experiments that showed it was caused by RNA degradation, something never before seen in an RNA virus." Exactly how that degradation takes place, how an RNA virus can preserve its integrity when it makes a protein that breaks down RNA, and whether...

Flick of a protein switches immune response

...nt of the immune system by changing partners in an elegant genomic dance, said researchers at the University of Southern California and Harvard Medical School. Because autoimmune diseases ?such as arthritis, allergies and dozens of other illnesses ?begin when the body's defenses respond at the wrong time o...

Evolution of 'irreducible complexity' explained

...d molecular methods to unravel the evolution of an elegant example of molecular complexity ?the specific partnership of the hormone aldosterone, which regulates behavior and kidney function, along with the receptor protein that allows the body's cells to respond to the hormone. They resurrected the ancestra...

Rewind, please: Nature paper shows that cell division is reversible

... other conditions. "Dr. Gorbsky's results provide elegant proof that the cell cycle must be precisely controlled," said Dr. Rodger McEver, OMRF vice president of research. "Now he and his lab can work toward developing innovative methods to probe and better understand the complex process of cell division." ...

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

... penguins somehow overcome this. They may have an elegant movement strategy for stability that we're unaware of." Kurz hopes that learning about the penguin's distinctive waddle will help those with walking challenges, such as the elderly, those with leg or foot injuries and toddlers learning to walk. The...

MIT chemist discovers secret behind nature's medicines

...Things are usually not this simple, but there's an elegant beauty in this simplicity," and it may be what gives other enzymes the prowess required for making other medicinally valuable halogenated natural products, too. ...

Scientist uses dragonflies to better understand flight

...to hover and even shift into reverse, the slender, elegant insect is a marvel of engineering. Z. Jane Wang, professor of theoretical and applied mechanics at Cornell University, presented her research on flying systems and fluid dynamics today (Feb. 19) at the annual meeting of the American Association for ...

Frog’s ear canal may provide insights for understanding human hearing loss

...her frogs don't have. "Our research points out an elegant and novel solution to the problem of communication in high levels of background noise," said Peter Narins, UCLA professor of physiological science and ecology and evolutionary biology, and co-author of the study. "In addition, we now add amphibians t...

Genetic key to growth of new arteries is identified

... "It's a very time-consuming approach, but a very elegant way to deal with the problem," comments Sarkar. "This paper is a very fundamental examination of the mechanisms involved in gene regulation in the growth of arteries." The next research step, according to Sarkar, will be to carry out the same experim...
