Stomach infections may be associated with irregular heart rhythm

...n the healthy volunteers. The levels of C reactive proteins were also higher in these patients than in people who had only spasmodic episodes of irregular heart rhythm. Researchers said that chronic gastritis caused by the Helicobacter pylori bacteria might lead to conditions of persistent atrial fibrillation...

Drug abuse may affect brain like Alzheimer’

...atisfaction. There was evidence of increase in key proteins related to brain damage in the brains of the drug abusers. One protein called Tau protein had turned insoluble in cells causing nerve cell damage and affecting the nerve cell functions in brain. Researchers report that the brain damage can be signif...

Developing a new vaccine using a new technology

...ble of efficiently delivering genes expressing HIV proteins to the immune system. IAVI will play a role in contributing technical expertise and funding and thus form a joint R&D team together with GSK. Members of the team say that the initial research will focus on designing vaccines to elicit immune respons...

Molecule responsible for muscle repair identified

...e damaged muscle. This had resulted in increase in proteins like the myogenic transcription factor MyoD that had led to faster muscle regeneration and repair after injury. Muscle regeneration after injury is important and when this does not happen due to disease or age, it may lead to muscles not being able...

MicroRNA provides new insight into birth defects

... are small RNA molecules that control the level of proteins made from transcribed genes. Researchers have discovered that there exists an association between the microRNA profile of the human beings and the development of tumors in different parts of the body. The new study will open new ways of exploring th...

New Discovery May Help Treat Infertility

...ogen receptor beta is one of two estrogen receptor proteins which mediate the effects of estrogen hormones and are present throughout the female reproductive tissues. The new data indicates that this receptor plays a critical role in ovulation, and suggests that women who do not have this receptor may benefit...

Molecular markers for early diagnosis of breast and ovarian cancer

...nd ovarian cancer. However, they did not find the proteins in women without cancer. "Attempts to find a single reliable early protein, or 'marker', for breast or ovarian cancer diagnosis have not been very successful," says LICR's Serhiy Souchelnytskyi, senior author of the study. "However, the use of multi...

The Link Between Oxidized Phospholipids And Coronary Artery Disease

...g to another recent study researchers suggest that proteins and enzymes that remove or destroy oxidized phospholipids prevent atherosclerosis and that proteins and enzymes that produce or retain oxidized phospholipids promote atherosclerosis , hence they say t...

Secret Of Heartbeat Protein Unravelled

...this role, it serves as a sort of tether, grabbing proteins inside the cell critical to nerve signalling and keeping them close to N-methyl-D-asparate (NMDA) receptors at the cell surface. NMDA receptors help usher in a neurotransmitter called glutamate that is essential for learning and memory and also pla...

Scientists Identify Cancer Pathway

...hway exists in real-world systems while the actual proteins that act on the system may vary. In the model sy...pstarts a series of cascading interactions between proteins in the cell that ultimately block some cell-surface proteins from entering through the cell's membra...

Turmeric Found To Slow Down Melanoma Growth

...time. Curcumin was found to suppress two specific proteins normally part of an intracellular pathway that prevents apoptosis when stimulated. Curcumin partially inhibited NF-êB and strongly inhibited its upstream stimulator and another independent inhibitor of apoptosis, IKK. However, it did not suppress two...

Identified Protein To Inhibit Cell Migration

...ion by adding a phosphate group to a host of other proteins in the cell. Thus, the study suggests that CIB1 may be a likely target for new drug development aimed at decreasing tumor metastasis, or spread, throughout the body. CIB1 plays a prominent role in the activation of PAK1 and potentially may be anot...

Integrin helps healing process in cells

...covery came when scientists analyzed two different proteins on skin cells. The first integrin was called alpha (3) beta (1) and worked as a sort of tug boat that helps cells move along and respond to chemical messages sent out by the wounded tissue. These chemical messages and this first integrin join forces,...

Protein causing spread of colon cancer identified

...erted them into proteins.// Thousands of different proteins were injected into the mice, and two, Pa28 being o... The investigators are now researching if these proteins are capable of being expressed in human tumour biopsies. This being successful, the next step would ...

Expose on eating disorders!! Scientists trace “brain’s eating control center pathway”

...of brain cells respond to hormones, among them two proteins called leptin //and neuropeptide Y, that control eating behavior. Other areas of the brain that play a role in eating decisions have not been identified before now, according to Dr. Jeffrey Friedman of The Rockefeller University in New York. ...

AIDS research and genetics...

... variations in genes that produce the cell surface proteins that HIV must latch on to in order to enter the cell. The resulting variations in cell surface proteins in those few patients ensure that HIV can't get in easily. The virus then is unable to replicate as ...

Scientists use plastic to help body make new bone!!!!

...ouston, Texas. Built into the plastic scaffold are proteins called growth factors, which are released as the plastic degrades inside your body. The proteins help entice blood vessels from the healthy surrounding bone to invade the damaged area, bringing nut...

Disease chromosomes identified

...es that act as instructions for the manufacture of proteins controlling everything that occurs in the body. HGP indicates that when genes mutate or are damaged, they cause heart diseases. cancer, Alzheimer's and numerous other ailments which have strong genetic components. The Cambridge scientists found th...

The anxiety gene

...tists do know that some of these genes manufacture proteins that play a crucial role in controlling the way th...ay be that an imbalance in the production of these proteins makes the brain over-sensitive to stressful situations. The team is now trying to identify exactly ...

Gene in Melanomas
