An alternative, safer approach is made a vaccine of small fragments of proteins produced by a disease-causing virus or bacterium.
This has worked for some diseases, but in many cases these vaccines don provoke a strong enough response.

#New way to model sickle cell behavior Patients with sickle cell disease often suffer from painful attacks known as vaso-occlusive crises, during
and Vannevar bush Professor of Engineering Emeritus, have developed a tiny microfluidic device that can analyze the behavior of blood from sickle cell disease patients.
It could also help researchers test the efficacy of new drugs for sickle cell disease which occurs in about 300,000 newborns per year, more than 75 percent of them in Africa.
Squeezing by People with sickle cell disease, an inherited genetic disorder, have a variant form of hemoglobin that causes their red blood cells to take on a characteristic sickle shape when in low-oxygen conditions.
Disease severity varies among patients depending on how much abnormal hemoglobin is present in their cells. Sickle cells can squeeze through most blood vessels
Analyzing risk Using this device to measure blood samples from 25 sickle cell disease patients, the researchers were able to determine how deoxygenation affects red blood cellssickling rates;
if the device can be used to reliably predict individual patientsrisk of a vaso-occlusive crisis. his technique represents a major advance to further our understanding and treatment of vaso-occlusion due to sickle cell disease.
and treating other diseases where the deformability of blood cells is affected, says Guruswami Ravichandran, a professor of aeronautics and mechanical engineering at Caltech who was involved not in this study.
and they also plan to pursue it as a tool to test potential new drugs for sickle cell disease.
the researchers analyzed a drug called Aes-103, now in phase II clinical trials to treat sickle cell disease,
and ultimately may also lead to long-lasting devices for treatment of conditions such as Parkinson disease.
Historically, these genetic brain diseases were viewed as untreatable. However, in recent years neuroscientists have shown in animal models that it is possible to reverse the debilitating effects of these gene mutations.
and that a treatment developed for one disease produced a cognitive benefit in the other. The research was performed by postdoc and lead author Di Tian, graduate student Laura Stoppel,

Now that we've created the first proof-of-concept biosensor using epitaxial graphene we will look to investigate a range of different biomarkers associated with different diseases and conditions as well as detecting a number of different biomarkers on the same chip.
More frequent tests could lead to better control of the disease which could lead to an associated reduction in health risks.

They can also track protein buildup in numerous degenerative diseases such as Alzheimer s or Parkinson s. In fact nanoscopy can even be used to visualize the individual proteins in fertilized eggs.
They also guided the CRISPR to attack bacterial genes that make the microorganism capable of causing disease in the first place.

After that, Kingsmore team used in-house software to search through the mutations for those associated with a disease that matched the baby symptoms.
In other cases, the genome scan allowed doctors to rule out diseases, which Kingsmore says can be equally valuable. octor always worry:
But if a certain disease-associated mutation isn found, doctors needn give justin-case treatments.
