Sodium Nitrate Destroys The Bacteria That Plugs The Air Passage In CF Patients

...s derivatives does not have any ill effects on the cultured human airway epithelia. The researchers say that nitrites could be inhaled and be part as the CF therapy. The patients can continue with this therapy until they develop the normal strains and starts showing signs of improvement. Later on the patients...

Vaccine to protect birds against avian flu, engineered

... than those prepared by traditional methods. It is cultured in cells and very easily produced in large amounts. It prevents the spread of the virus in domestic livestock populations and humans. The findings were published in the Journal of Virology. Andrea Gambotto, M.D., assistant professor in the departme...

Little Known DNA Repair Enzyme May Be A Tumor Suppressor Gene

...ev3L knockout mice, the investigators isolated and cultured MEFs from all the offspring of the matings to see if any would grow. To start with, the cells all failed to divide. However, three months later, some cells began to grow and at a surprisingly robust rate. Dr. Wittschieben said, "Since the only Rev...

Treatment of Sickle Cell Anemia Using Gene Therapy.

...s. The stem cells taken from the bone marrow are cultured in the lab and a small RNA sequence that interferes with the production of beta S-globin is integrated. This is because this sequence that produces beta S-globin is altered in these patients hence the altered gene is prevented from getting translated...

Scientists Discover Secret Of Curly Hair

... and straight European hair in the laboratory. The cultured follicles revealed key structural differences. "The curl in African hair is not limited to its shaft, but exists already in its bulb. On the contrary, the bulb of a straight hair is itself straight," the researchers were quoted as saying. "A curl...

Human neurons grown in the brains of mice

...ct evidence that primitive human stem cells can be cultured in the lab, be injected into an animal, and then d...Sciences. Scientists say this is the first time cultured human embryonic stem cells have been shown to develop into a particular type of cell in the body of ...

New anti-aging molecule could be coming up in way

...ained unclear. A research recently carried out on cultured cells (grown in laboratory conditions) and in experimental animals has now revealed that the protein works by increasing the cells ability to inactivate reactive oxygen species. The protein has been found to act by activating an enzyme called manga...

Morphine Withdrawal Complicates Hepatitis C Infection in Drug Abusers

...ffects of morphine withdrawal (MW) on HCV-infected cultured liver cells by exposing cells to the drug for four days followed by its removal. They also assessed the effects of using naloxone. To measure HCV replication, they used a virus-like “replicon” that mimics the events that occur in liver cells. Altho...

Aspirin May Protect Against Hyperglycemia With Diabetes

.... For these purposes, human endothelial cells were cultured in normal concentration glucose or high concentration glucose and after confluence, exposed for 48 h to high concentration glucose in the absence or presence of 1 mM aspirin. Then, the intracellular calcium ion concentration was measured fluorimetric...

Citrinin, a fungal toxin, induces apoptosis via mitochondrial pathway

... effects of these mycotoxins on animal tissues and cultured cells are thought to correlate with their apoptosis-inducing ability. A recent paper, to be published in Toxicology Letters (available online 23 September 2005), reports that CTN induces apoptosis through the mitochondria-dependent pathway in human...

The Polymicrobial Nature Of Diabetic Foot Infections

Resilin Protein from Flea can be used for cardiovascular disease

...he genes responsible for resilin from the flea and cultured them in the bacteria E.coli and found that it could produce super strong rubbery polymer. They found that this resilin can be stretched to more than three times their original length without causing any damage or break in the resilin. The artificia...

Swiss Researchers Isolate Hair-Raising Stem Cells

... cells from rat whisker follicles labeled them and cultured them for 140 generations. These cells were injected into the skin of newborn mice and then the skin graft was given to nude mice. It was found that these progeny cells participated in the formation of eight types of cells including outer root sheath,...

Vitamin D With NSAID Drugs May Prevent Prostate Cancer

...-counter anti-inflammatory drug on prostate cancer cultured cells, reports the online edition of Ivanhoe Broadcast News. The researchers saw a 25 percent reduction in prostate cell growth using only calcitrol. They noticed approximately the same reduction using only ibuprofen or naproxen. But the prostate ...

Researchers Identified Process That Aids Spread Of Alzheimer’s’ Diseae

...functions – which is fatal to the organism. Using cultured human and mouse cells, as well as test-tube assays, UT Southwestern researchers singled out how just one portion of the enzyme, a protein called nicastrin, is involved in the pathway that produces beta-amyloid, thereby leading to Alzheimer’s disease....

Enzyme Responsible For Congenital Blindness

... researchers had performed an expression screen in cultured human cells, looking for a gene that caused these cells to convert vitamin A into 11 cis retinol. The researchers are now studying the effects on retinoid isomerase activity of specific disease causing mutations in the RPE65 gene, which should prov...

New molecule to treat brain disorders found

...that adenosine did have a beneficial effect on the cultured brain cells. While it is not clear if the molecule would have the same effect under more complex circumstances found in the body, researchers are hopeful that they can deliver adenosine to the brain, where it could protect cells from damage. ...
