Food packaging with Bisphenol A damages the brain

...ecause oestrogen normally increases the growth and regulates viability of developing neurons, he said, these results support the idea that BPA may harm developing brain cells. 'From other studies it's clear that these low concentrations are in line with human foetal exposures, and at levels one might even see...

Scientists breaking theory of cortex formation

...protein that binds DNA at a specific site where it regulates transcription, or the process of copying genetic material. In the brain's early prenatal development, transcription factors control the birth and growth of new neurons, neurons' movement and connectivity within the brain, and which ones live and wh...

Scientists Discover Hormone That Controls Hunger

...cientists in the US have discovered a hormone that regulates hunger and may help to fully control appetite in the future//. Researchers at Stanford University, California, looked at gene sequences in humans and animals, including one that codes for ghrelin, an appetite-boosting hormone. They found another h...

Leptin and inflammatory cytokines in women with pre-eclampsia

...tetrics and Gynaecology. Leptin is a hormone that regulates metabolic efficiency, energy expenditure, and food intake. It is mainly produced in adipose cells, but in humans, m-RNA encoding leptin is also present in the placenta. Pre-eclampsia is associated with an increase in maternal plasma leptin concentra...

Protein Markers for Identification of Brain Tumor

...L-13), which is a naturally occurring protein that regulates the immune system in the body. Normal cells do not have these same receptors. Debinski developed a drug that combines a form of IL-13 with a toxin that kills cancer cells. By targeting the therapy to these receptors, the drug finds and kills the canc...

Researchers Identify Sipa 1 Gene, Responsible For Cancer Metastasis

... a GTPase activating protein (GAP) that negatively regulates RAP1 and RAP2 GTPases. Human SIPA1 has recently been found to interact with the water channel aquaporin 2 (AQP2), by its PDZ domain, so the authors used AQP2 to see if the Alanine to threonine substitution affected this interaction. Transient trans...

Fertility Treatment Offered During Summer Has Better Chances For Success

...dism, and is linked to the hormone melatonin, that regulates sleeping and walking cycles. It was believed that melatonin acted through the pituitary gland, which is "switched off" during IVF cycles, However, researchers have now found that melatonin is found in receptors throughout the reproductive system. Alt...

Sunlight For Healthy Gums And Teeth

...min D happens to be vital to the system in that it regulates calcium metabolism in the body. Even if adequate amounts of calcium are present in the body, Vitamin D is essential to maintain the balance of the mineral in bones as well as blood. Without Vitamin D, the chances of developing inflammatory disease in...

‘Inflammation Gene’ identified by scientit

A gene on chromosome 15 regulates inflammation according to scientists. Inflammation has a role to play in a wide range of disorders, including cancer, cardiovascular disease, diabetes, obesity, Alzheimer’s besides infections//. John Blangero, Ph.D. and senior author of the study s...

Dark chocolate can help ease symptoms of diarrhea

...n bind to and inhibit a protein called CFTR, which regulates fluid secretion in the small intestines. Children younger than the age of five and the elderly are the most likely to develop grave health problems if their condition leads to dehydration. In severe cases children or elderly patients with diarrhea ...

New Study Offers Hope For Balding Men

...w study shows that the mechanism by which Hairless regulates hair re-growth is by controlling the timing of a key signaling pathway. Bald mice that were genetically engineered to produce the Hairless protein were able to re-grow a thick fur. Lacking Hairless is a rare genetic disorder and is not the only r...

An Answer To Obesity: Weight Control Protein

...halamus. The current study shows that SH2-B also regulates energy balance and body weight by enhancing leptin sensitivity in animals, Rui said. Further examination found that the animals lacking SH2-B ate nearly twice as much as normal. Surprisingly, Rui said, the animals burned more calories; however, the ...

Genetic Cause For Farsightedness Discovered

...gene called MFRP that helps control eye growth and regulates the organ's shape and focus. The study is described in the July issue of the journal Proceedings of the National Academy of Sciences. As the child grows and gains more visual experience, the eye adjusts its focus by growing, which changes the distan...

Getting A Suntan The Easy Way

...c agent that is similar to the body’s hormone that regulates skin pigmentation. // In previous research, investigators showed MT-1 can induce tanning in human volunteers who are known to tan easily in the sun without the use of sunlight. Researchers conducted three different clinical trials to see if MT-1 is...

New Implantable Device That Can Keep The Heart Ticking

...ed defibrillator. A defibrillator is a device that regulates the heart rhythm like a pacemaker, but delivers an electrical jolt to reset the heart if that fails. Results show those who got the defibrillator were significantly less likely to die. During the initial follow up, 40 people in the standard treatmen...

Sox 18 Slows Cancers

...the colon, prostate,pancreas,brain and bowel. Sox regulates blood vessel development and could be manipulated to stunt the cancer by starving the tumour cells.// This discoverywas made by Peter Koopman and George Muscat at the University of Queensland's Institute for Molecular Bioscience. "Tumours cannot g...

Genes to Extend Longevity Discovered

...ate student Dudley Lamming, demonstrates that PNC1 regulates the whole SIR2 family of genes, suggesting that a human PNC1 gene might protect against diseases of aging such as cancer, heart disease and diabetes. This work was supported by the National Institute on Aging, the Paul F. Glenn Foundation, and th...

Gossypol helps in chemotherapy of neck and head cancer.

...at the U-M Comprehensive Cancer Centre. Gossypol, regulates the protein Bcl-xL which is over expressed in cancer cells, as a result the cells are able to survive. Two different cell lines were cultured in the lab and results observed. On the basis of the results the scientists have made this revelation. Sour...

New clues to maternal aggressive behavior

...ing the lactating phase, the oxytocin hormone also regulates the functions of hypothalamic-pituitary-adrenal axis that controls the anxiety levels. The researchers had started their investigations by directly inserting the oxytocin hormone in the brains of the virgin female rats and found out that the functio...
