Lancing tumours into the body

... who is designing tiny robots to manipulate single cells in the body that “surgeons are understandably cautious about the idea of microbots floating free in the body. If one blocked a blood vessel,” for example, it could be disastrous.He also says that Ishiyama’s prototypes might be too long to safely nav...

Gene Therapy For Cystic Fibrosis

New drug may stop alopecia

Genes for Vision discovered

A little more than half of the mutant genes for degenerative diseases of the retina had been identified when Cepko began his study. Using a computer program that compares snippets of genetic material taken from ...

The superior steroids

...n participants' blood. Eosinophils are white blood cells involved in defending the body from allergens. For best results, experts generally recommend that you use either an inhaled steroid or an antihistamine on a continuous, long-term basis. But the researchers point out that most people tend to wait un...

Artificial lenses- Boon to cataract patients

...logist at Emory School of Medicine in Atlanta. But cells left behind after surgery can proliferate and cause the lens capsule to stiffen, he says. For variable focus lenses, this could be a problem. If such trails are successful, they add, however, some patients might not need to wear glasses at all - unl...

Inherited gene important in ovarian cancer

... for genes to be lost due to a malfunctioning when cells divide - this can happen even if you inherit two normal copies. The study shows that BRCA1 is more significant in ovarian cancer than previously realised. This opens the door to new therapies for this hard-to-treat cancer - drugs which restore BRCA...

Cytobrush to detect oral cancer

.... “They can penetrate and get a better sampling of cells than the old scraping technique.” The sample is sent to a lab where it is scanned using advanced computer technology. Suspicious slides are tagged for further evaluation by a technician. The computer is so exacting, Green berg said, that the false ne...

Why cluster headaches?

...re likely to be caused by excessive growth of grey cells in one part of the brain. By using the latest imaging techniques, Professor Goadsby and colleagues found an increase of grey matter in an area of the brain known as the hypothalamus on the side where the headache occurs. Professor Goadsby said: "We...

Nasal Spray Beats Antihistamine

... histamine, a compound released from immune system cells during allergic reactions. Antihistamines can cause significant sedation, for example. And the nasal sprays sometimes cause nasal dryness and nose bleeds, while in children there is the potential for the corticosteroids to hinder bone growth over tim...

High vitamin A increases risk of hip fractures

...id previous studies also suggest vitamin A affects cells that work in bone remodeling. The adverse effects appear to be caused only by too much retinol -- the true form of vitamin A, found in such things as liver, fish oils and supplements - and not by foods rich in beta carotene, such as dark, leafy vege...

Water regulation in humans

Recently developed compounds that can block the uncontrolled SHH signaling found in the tumors could potentially be us...
