DNA Molecules Used To Assemble Nanoparticles

...usters are in the works. "If you wanted to make a therapeutic that targeted five drugs to five different cells, it would be 25 synthesis steps the traditional way," Baker said. At two to three months per synthesis, and a significant loss of yield for each step, that approach just wouldn't be practical. Instead...

Wisconsin scientists grow critical nerve cells

... UW-Madison. 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 embryonic stem cells into motor neur...

Spleen may be source of versatile stem cells

...report. "Ifso, these cells could have much broader therapeutic applications thansuggested by our earlier work."In 2001 Faustman's team found that a treatment designed to address theautoimmune reaction underlying type 1 diabetes actually cured thedisease in diabetic mice. Late in 2003 they reported the mechanismb...

...needed to turnembryonic stem cells into cells with therapeutic potential," saidBhatia. "We think we've developed an enabling technology for stem cellresearch and other areas of cell biology in the sense that all of asudden scientists can use inexpensive and widely available reagents andmachinery to optimize the ...

Neuronal 'traffic jam' marks early Alzheimer's disease

...res could prove valuable in testing diagnostic and therapeutic approaches, said Goldstein. The researchers are also analyzing more brain tissue samples from humans with Alzheimer's disease, to confirm their findings of the early transport defects and their effects on neuronal death. ...

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

...tovase. The researchers emphasize that the drugs' therapeutic benefits are still greater than the risk of heart problems linked to their use. They urge physicians to apply this new finding by following their patients more closely over the long term, and by looking specifically for heart rhythm irregularities in...

Scientists seek answers on what activates deadly anthrax spores

...ural vulnerabilities that are key to designing new therapeutic agents to prevent anthrax. Interest in determining how to stop anthrax remains high, not only after the 2001 attacks through the mail that resulted in 18 cases and five deaths, but also after the recent scare at two military mailroom facilities when...

"Since ...

UCSD researchers maintain stem cells without contaminated animal feeder layers

... provoke an immune system attack eliminating their therapeutic value. While several laboratories have attempted to grow stem cells in alternative cultures, problems have remained. In some cases, human feeder layers were developed but this added another measure of complexity to the culture system, Hayek noted. I...

Researchers add new tool to tumor-treatment arsenal

...y of cancers," says Dr. Thomas. "However, a narrow therapeutic window, combined with possible severe side effects, has greatly limited their broader use." These factors, says Dr. Thomas, have probably contributed to recent reports of the under-dosing of patients and the failure to blunt the disease. When cance...
