DNA Molecules Used To Assemble Nanoparticles

...ast 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 yield of useful particles drops with each successive step of synthesis. For a paper published Jan. 21 in the journal Chemistry and Biology, U-M...

Scientists have long believed in the therapeutic promise of embryonic stem cells with their ability to replicate indefinitely and develop into any of the 220 different types of cells and tissues in the body. But researchers have struggled to convert blank-slate embryoni...

Elusive HIV shape change revealed; Key clue to how virus infects cells

...lurry picture," explains Harrison. "It took a very long time, and lots of computational work, to get that picture to sharpen up enough to get an answer." One of the lab's first steps will be to determine which shape of gp120 ?bound to the CD4 receptor, or unbound ?is recognized by a person's antibodies. ...

Then they fragment th...

HIV Patients May Be at Risk of Heart Problems When Taking Protease Inhibitor Drugs

Histone acetylation was long thought to influence transcription by regulating the structure and function of chromatin, which is an assembly of proteins (mostly histones) and DNA. Another, more widely accepted model proposes that histone acetylation controls transcription by recr...
