St. Jude announces breakthrough in eye cancer treatment

...and less toxic. Ideally, these treatments could be administered even in countries that cannot afford the highly complex infrastructure now required to manage children with retinoblastoma. This would mean saving many more lives and preserving more vision." Rodriguez-Galindo is a co-author of the paper. Retinobla...

Researchers show that veins stiffen as we age

...ld water, or while squeezing a handgrip. They also administered a nitroglycerin pill under the tongue of each participant to relax the veins. In each case, they found that the tests had no effect on the response of the veins in either age group. "Thus, we think that the stiffening of our veins as we age is prob...

New approach could lower antibiotic requirements by 50 times

...udomonas survived if the antibiotic gentamicin was administered in the presence of bacteriophages. None survived without the phages (Microb. Drug Resist., 2006, 12 (3), 164). The bacteriophage approach would also be particularly useful for treating cases of food poisoning, because the lower doses of antibiotic ...

MIT: Pulsing light silences overactive neurons

..., allowing treatment (either shock or light) to be administered only when necessary, Boyden said. The technique also offers a way to study other brain diseases, as well as normal brain circuitry, offering insight into which brain regions and neurons contribute to specific behaviors or pathological states, Boy...

Stem cell therapy shows promise in regenerating damaged muscle in heart attack patients

...s manufacture, Osiris Therapeutics. Patients were administered an infusion of either Provacel or placebo within 10 days of having a heart attack and are being followed for 2 years. To prevent bias, neither the patient nor the physician knows who received the stem cell treatment and who received placebo. Rush...

A better knowledge of this influence should make for better understanding of the differences between men and women, particular...

A revolution in the monitoring of unborn babies

...this technique has proven benefits, it needs to be administered by trained professionals and it is not suitable for routine, continuous, long-term monitoring. Dr Barrie Hayes-Gill and Dr John Crowe at The University of Nottingham recognised the need for a new technology that would fill these gaps. One of the ...

Lead-'scrubbing' drug may also improve muscle function in lead-exposed children

...echnique, nicknamed “scrubbing,?in which a drug is administered to seek out and bind to poisonous heavy metals, such as lead or mercury, in the bloodstream. The compound resulting from this binding is then excreted in the urine, essentially cleaning out the dangerous metals. Succimer (Chermet) is an oral chela...

Between the tests the children and escorting parent(s) were interviewed about dietary and seasoning preferences. The children were then invited to eat freely from a table of salty and sweet snacks. ...

Intravenous nanoparticle gene therapy shows activity in stage IV lung cancer

...stage 4 lung cancer patients via an intravenously administered lipid nanoparticle in a phase I clinical trial at The University of Texas M. D. Anderson Cancer Center. The gene, FUS1, also was found to be active in the metastatic non-small cell lung cancer tumors. "We've treated 13 patients in this first-in-hu...

Antivirals effectively curb influenza virus

In addressing the limitations to their research, the authors call for further studies into antiviral efficacy. "Trials in non-household settings where influenza readily spreads ?such as scho...

Producing medicines in plant seeds

...man proteins. These proteins are then purified and administered as medicines. Examples of such proteins are antibodies, which can be used, for instance, in the treatment of cancer. The conventional methods for producing antibodies work well, but they are expensive and have a limited production capacity. The high ...

Dual gene therapy suppresses lung cancer in preclinical test

...separately but had their most powerful effect when administered together, cutting the number of tumors per mouse by 75 percent and the weight of tumors by 80 percent. "In cancer treatment we have combination chemotherapy, and we also combine different modes of therapy - surgery, radiation and chemotherapy. Now...

They also conducted brain imaging studies to assess brain metabolism and cognitive activation using PET scans. All of t...

Study shows hope for early diagnosis of Alzheimer's

...r her brain has been examined. Gold standard tests administered at world-class research facilities, such as Penn, have a 90-percent accuracy rate. However, most people are evaluated at community hospitals and clinics, where the diagnostic accuracy is estimated to be around 75 percent. Though the study’s accura...

Chlamydia vaccine a step closer to reality

...said once a vaccine had been developed it could be administered via a patch, similar to ones used by smokers for nicotine. "Patches are a good way to deliver proteins to a part of the body's immune system and they are also easy and user-friendly." He said with rates of Chlamydia infection in some Australian...

Glucose triggers brain cell death in rats after hypoglycemic coma

... hypoglycemic coma actually occurs when glucose is administered to treat the coma, according to a study in rodents led by researchers at the San Francisco VA Medical Center. The results are surprising, say the authors, and may be of clinical significance for the treatment of diabetics in hypoglycemic coma, thou...

UCI scientists reconstruct migration of avian flu virus
