FDA sees nanotech challenges in every product category it regulates

... Task Force about the agency’s regulatory approach toward nanotechnology—an exciting new field of engineering and science that is estimated to grow to $2.6 trillion in manufactured goods globally by 2014. As the Task Force report highlights, nanotechnology impacts every area of FDA responsibility—drugs, dru...

Identified main genetic variants involved in response to HIV

...velopment. This and similar studies should push us toward more personalised medicine, where the most suitable drugs for each individual would be determined on the basis of their gene characteristics....

Cellular message movement captured on video

Innovative smallpox vaccine research study to be conducted at Case Medical Center

...and effectiveness of a new smallpox vaccine geared toward adults ages 18 to 34 who have never been vaccinated against the disease. The study is the first of its type in Northeast Ohio. The current FDA-approved vaccine, Dryvax®, is not recommended for use on everyone because of the potential for serious si...

Studies to find better ways to preserve human eggs, ovarian tissue under way

...e one she directs at MCG Health System, are moving toward vitrification, which also seems to work faster, better and cheaper in embryos. They pursue the potential of egg preservation as well to really find out which is the best option: ovarian tissue or pure eggs. Also, a better way to preserve eggs – w...

In mice, drug protects against diabetes and atherosclerosis

... detailed toxicity tests in animals, and then move toward human testing. The important lesson from the new study, the researchers wrote in their report, is the demonstration that aP2 can be blocked by a small-molecule, oral compound. In turn, they add, the results suggest that targeting aP2 "can lead to ...

Researchers reveal structure of protein altered in autism

...n neuroligins and neurexins represent a major step toward defining the synaptic organization at the molecular level. “Normally, individual neuroligins are encoded to interact with specific neurexin partners. The two partners are members of distinct families of proteins involved in synaptic adhesions, im...

Women well informed about breast cancer, yet lacking knowledge about current treatments

...tween awareness and information that women can use toward better treatment. “These survey results suggest that many women still lack essential disease treatment information, which reinforces the need for women to educate themselves to help get the best treatment,” said Diane Blum, MSW, executive d...

Australian wins prestigious prize in biodiversity informatics

...tists and non-scientists. Flemons' Prize will go toward engaging a broader community in the establishment of standards for data and metadata that arise from biodiversity collection and monitoring, and in furthering his work in building tools for online biodiversity analysis. He said " I look forward to...

New findings challenge established views on human genome

...equencing of the genome marked just the first step toward the goal of using such information to diagnose, treat and prevent disease. Having the human genome sequence is similar to having all the pages of an instruction manual needed to make the human body. Researchers still must learn how to read the manual...

Exploring the dark matter of the genome

...uence of heterochromatin is clearly a crucial step toward a better understanding of genome functions. Karpen notes that one intensively studied and puzzling problem in chromosome biology will benefit enormously from the new findings: epigenetics -- the inheritance of traits and genetic information as c...

Surprising origin of cell's internal highways

...microtubules originating at the Golgi are directed toward the cell "front," or the leading edge, of motile cells. Since such an orientation is needed for directional migration, Kaverina hypothesizes that this subset of microtubules may influence cell motility by facilitating the transport of proteins needed...

Scientists close in on missing carbon sink

... The models tended to move too much carbon dioxide toward ground level in the summer, when growing trees and other plants take in the gas, and not enough carbon dioxide up in the winter. As a result, scientists believed that there was relatively less carbon in the air above mid-latitude and upper-latitude f...

Lessons from the orangutans: Upright walking may have begun in the trees

...ns as other researchers have envisioned. Somewhere toward the end of the Miocene epoch (24 to 5 million years ago), climate in East and Central Africa became alternately wetter and drier, and the rainforest grew increasingly patchy. Apes living in the forest canopy would have begun to encounter gaps between...

A cherry on top: Tart cherries may alter heart/diabetes factors

...similar diet. All of the rats had a predisposition toward high cholesterol and pre-diabetes, but not obesity. All the measures on which the two groups of animals differed are linked to metabolic syndrome, a collection of risk factors linked to high rates of heart disease and Type 2 diabetes. Tens of mil...

More recycling on the farm could reduce environmental problems

... problems resulting from farming argue for a shift toward practices that use lower inputs of pesticides and energy and more recycling of energy and materials, according to an article published in the May 2007 issue of BioScience. The author, Craig J. Pearson of the University of Guelph, documents how semicl...

US control strategies may make flu epidemics worse, UCLA study shows

...." Blower and her group used people's attitudes toward the seasonal flu to construct their model. With seasonal flu, protective immunity ?a flu shot ?lasts only one year. Thus, individuals must decide each year whether or not to participate in a vaccination program. The model Blower's team developed ...

Anthrax paralyzes immune cells with lethal toxin, UF research shows

...n rod-shaped filaments called actin to propel them toward an infection. In a previous study, Southwick found that the toxin prevents actin assembly, leaving neutrophils stuck in the mud. "Actin is important because it's the motor that causes neutrophils to move," said Southwick. "So it's like cutting the...

DOE JGI sets 'gold standard' for metagenomic data analysis

...ll the methods that have been developed were aimed toward analyzing data coming from single, isolate genomes. In this instance, the situation is simple; we know what gene belongs to which organism. In metagenomes, it's much more challenging, because you have sequences from many different organisms all mix...

Better health twice as likely for nonsmokers who live and work with smoking restrictions

"As the policy environment continues to move toward comprehensive protection at the workplace, the household increasingly will become the main and perhaps the only significant source of exposure among nonsmoking adults as it is among children," observes Donna Shelley, MD, Mailman School assistant prof...
