Early detection of bed sores possible

...healing and may not reach the site of the wound. A molecule called c-myc causes this sudden stop of the healing process, causing the skin to thicken, get in the way of the cells that can repair the wound from reaching the site of the wound. Researchers had successfully traced the overproduction of the molecul...

Scientists Unveil Mechanism Behind Resistance to Severe Malaria

... specific type of hemoglobin — the oxygen-carrying molecule that gives red blood cells their color — are less prone to severe malaria. In a series of experiments, the researchers determined how hemoglobin type C impairs the ability of malaria parasites to cause disease symptoms. “This research gives us a new...

Detecting DNA Damage With In-Vivo Alkaline Comet Assay

... the duplex DNA leads to difference in size of the molecule and these fragments can be stretched out by electrophoresis. The image obtained consists of a head made up of intact DNA and a tail, which represents the fragmented DNA. Under alkaline conditions, unwinding of the double strand takes place, which ena...

PET Scan find the Area of Brain Responsible for Anorexia Nervosa

...nforcement and reward. Researchers used a harmless molecule designed to bind to the dopamine D2 and D3 receptors that lie on the membrane surface of neurons. Ten women who had recovered from anorexia nervosa for more than a year were studied, as were 12 normal female subjects. Because malnourishment affects b...

Research identifies trigger that sets of Huntingtons disease

Researchers have discovered the key molecule that gets over activated by the protein of the Hun...edicine, who had conduced the study, feel that the molecule p53 may also be responsible for Parkinson's disease and amyotrophic lateral sclerosis, also called L...

Molecule responsible for muscle repair identified

...le to heal itself.// Researchers have identified a molecule that when is deficient, is actually helpful to muscle regeneration. Researchers from University of Illinois-Chicago had reported in their findings that deficient plasminogen activator inhibitor-1 (PAI-1) promotes muscle regeneration and this may be...

Revolutionary Simple Pregnancy Blood Test Can Save Both Mother And Child

...wn the cause of the disease and found this to be a molecule secreted by the placenta. The molecule is called ‘HLA-G molecule ‘ and is a protective substance that helps in preventing the mother's body...

Controlled Gene Expressions Can Cure Many Diseases

...DNA in two ways. First, they developed a synthetic molecule called a peptide nucleic acid, or PNA, which physically binds to DNA and blocks enzymes from copying, or transcribing, the DNA into messenger RNA. More importantly, the researchers also employed RNA itself as a silencing agent. The researchers desi...

Secret Of Heartbeat Protein Unravelled

...ein's structure is solved, scientists can create a molecule to disable it. That, in turn, will allow them to fully understand SAP97's role in the body. And that will point drug makers to targets for developing new ways to treat cardiac or neurological diseases, he said. Indo-Asian News Service...

Scientists use plant hormones to fight cancer

...who was part of the research team, said fragmented molecule is released only within the tumour thereby killing only cancer cells and healthy cells are not harmed in anyway. In laboratory studies if cell cultures Wardman and his colleagues used an enzyme called peroxidase, to trigger the release of the to...

New molecule to treat brain disorders found

...ain disorders, researchers say, Adenosine, a small molecule that plays important roles in controlling the hear... 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 hopef...

Fat Cell Protein Hits Type-2 Diabetes

... working in the liver, and then creating a smaller molecule that will mimic the effect of Acrp30 or perhaps finding a way to stimulate the secretion of Acrp30 within the fat cell," Roseveltte said. "Either of these strategies will be targets of companies trying to develop drugs from this kind of research."...

Withering related to impotence

...tric oxide."This substance, well known as a signal molecule in humans, is made in response to ABA and causes the formation of a messenger molecule that acts inside the guard cell," said Dr Neill. Guard cells are the cells surrounding the stomata...

Gene in Melanomas

...risk factor.The gene codes for the Cdk4 protein, a molecule that promotes cell growth and proliferation. Melanomas, like all cancers, are caused by the unregulated growth of cells that spread via the blood to other organs in the body. The specific mutation in the Cdk4 gene renders the Cdk4 protein insensiti...

Phase 3 trials of two multi-kinase inhibitors against cancer

... multi targeted oncology drug candidate is a small molecule named Sorafenib (Bay43-9006) and stutent (SU11248). Sorafenib is produced by Onyx pharmaceuticals of California collaborating with Bayer pharmaceuticals of Connecticut and Stutent by Pfizer of New York city. Both these drugs are undergoing phase 3 ...

Slowing Down The Progression Of Tumour Cells With Omega-6 Fatty Acids

...urn stimulates the release of PGE2, a hormone-like molecule that promotes cell growth. Around 60 years ago, the dietary ratio of omega-6 to omega-3 in the US was one to two. Today, the ratio is 25 to one. Over that same 60 years, the incidence of prostate cancer in the US has increased steadily shows a rece...

Enzyme Responsible For Congenital Blindness

...ght exposure. Rhodopsin contains a light-absorbing molecule called 11 cis retinaldehyde, related to vitamin A, which is converted upon light absorption to all trans retinaldehyde in a process called photo bleaching. This conversion is the first step in visual perception. Photo bleaching leaves the rhodopsin ...

Understanding The Role Of Olfaction In Taste

... sense, in that the brain perceives the same smell molecule differently if it arrives through the nose, rather than the mouth. // Based on a recent study researchers at Yale University report that the smell of chocolate could activate different brain regions according to whether the odour was sniffed or tas...

New Blood Test To Detect Iron Level In Infants

...Hemoglobin is the iron-containing, oxygen-carrying molecule in red blood cells; the CHr test measures the hemoglobin content of reticulocytes, or immature red blood cells, whereas the standard hemoglobin test is based on the entire population of red blood cells. Because reticulocytes are present in the bloo...
