DNA Molecules Used To Assemble Nanoparticles

...rray of molecules on the ends of their arms. It is possible to build a single dendrimer carrying many different kinds of molecules such as contrast agents and drugs, but the synthesis process is long and difficult, requiring months for each new molecule added to the dendrimer in sequential steps. And the yiel...

Scientists ID molecular 'switch' in liver that triggers harmful effects of saturated and trans fats

...ious, and what we need to avoid." Moreover, it is possible that in the future, drug therapy might be used to "turn down" the mechanism, decreasing cholesterol levels and heart disease risk, explained Spiegelman, who is also a professor of cell biology at Harvard Medical School. Saturated fats are found in f...

By switching on themelanopsin it could be possible to restore the eyes ability to respondto light.Although making cells in the eye responsive to light is not a cure forblindness, the team are collaborating with engineers from Imperial todevelop a functional retinal prosthesis which would allow theinf...

Source of molecular triggers in cutaneous T cell lymphoma identified

... types of lymphomas," said Edelson. "It may now be possible to identify specific antigens and target the malignant cells with selective poisons delivered through the vehicle of LC." The study also showed that CTCL cells, after stimulation by LC, become functioning regulatory T (Treg) cells that suppress the ...
