Trials for new drug to overcome HIV

...om the blood, driving down the levels tenfold in a matter of hours. The trial planned for this month is intended to discover how the drug performs as part of a combination treatment with other anti-HIV drugs, which is a more realistic situation. Fortyeight patients whose existing drug regimes are failing w...

Origen publishes in Nature a robust and versatile method for creating transgenic chickens

...antibody identification to production in eggs is a matter of months, the purification of proteins from eggs is relatively simple, and good manufacturing practices have long been established for vaccine production in chicken eggs. Moreover, the overall cost of facility and operations is a fraction of that as...

Immune system police learn early and sometimes badly

...ons of roaming T cells. They found it was a simple matter of numbers: by wearing many hats, or antigen receptors, regulatory T cells can keep their eyes on a lot of different non-regulatory cells. "The next question we will ask, which is a hot topic right now, is what antigens trigger receptors on regula...

DOE publishes research roadmap for developing cleaner fuels

...us, woody and generally inedible portions of plant matter (biomass). The focus of the research plan is to use advances in biotechnology -- first developed in the Human Genome Project and continued in the Genomics: GTL program in the Department's Office of Science -- to jump-start a new fuel industry whose ...

...2006). "People often believe that happiness is a matter of circumstance, that if something good happens, they will experience long-lasting happiness, or if something bad happens, they will experience long-term misery," he says. "But instead, people's happiness results more from their underlying emotional ...

Researchers unveil strategy for creating actively-programmed anti-cancer molecules

...mparison, the small molecule drug was cleared in a matter of minutes. "Although the study focused specifically on breast cancer, these new findings could have broad application in the treatment of a number of other cancers, potentially increasing the efficacy of a number of existing or undeveloped small m...

Scientists identify gene involved in stem cell self-renewal in planaria

No matter how you slice it, the freshwater planarian possesses an amazing ability to regenerate lost body parts. Chop one into pieces, and each piece can grow into a complete planarian. The flatworm relies upon a population of stem cells to accomplish this rem...

New strategy rapidly identifies cancer targets

...he patient to the right drug will then simply be a matter of running their cancer cells through a future version of their new technique. Druker is already testing the idea. "Now we know to add JAK3 to the mutations we screen for in our leukemia patients and should look to see if JAK3 mutations are pres...

Protein-coated dental implants could improve bone regeneration

...thin a week or two," he says. "After that, it's a matter of the wound maturing ?going through the various stages of healing that we're already familiar with." By experimenting with treatments and discerning their effect on healing bone defects, they found some ?including some in use today ?that actually ...

Bacteria can help predict ocean change

...ter temperature, salinity, nutrient content, plant matter and other variables. The researchers found they could predict the makeup of the bacterial population by the conditions in the water more than four times in five. A majority of bacterial species came and went predictably, Fuhrman said. A smaller "...

Cornell researchers find serious fish virus in Northeast for first time

...reat a threat in North America. "Right now, it's a matter of trying to collect as much information and as fast as possible so we can to notify the DEC so they can make management decisions." Cornell's role is to diagnose and research the disease for the state agency. Bowser and colleagues are trying to de...

Connect the Quantum Dots

... Nanotechnology, the understanding and control of matter at dimensions of roughly 1 to 100 nanometers, is valuable research since matter at the nanoscale has unique properties that enable novel applications. Medical researchers work at ...
