Imaging study affords renewed thrust on smoking cessation treatments

...urred in the thalamus (a portion of the brain that acts as a conduit for all sensory information that reaches the brain's cerebral cortex, and which contains the highest concentration of these nicotine receptors), the brainstem (which controls various automatic functions, such as respiration, heart rate, ...

'Blimp1' Gene Linked To Oily Skin

...inds of cancers. Horsley found that Blimp1 usually acts to repress c-myc expression, and in mice without Blimp1 c-myc expression was increased, causing the sebaceous gland to contain cells that divide more frequently. When Horsley tagged the Blimp1 positive cells and tracked them, she found that the daugh...

Timing of Food Consumption Activates Genes in Specific Brain Area

...y’s sleep/wake cycle, among other functions. Light acts on an area in the brain called the suprachiasmatic nucleus, or SCN. But because destroying the SCN doesn’t affect the body clock that paces feeding behavior, the circadian pacemaker for feeding must be somewhere else, Dr. Yanagisawa said. To find...

A Major Break Through in Treatment for Metabolic Syndrome

... pressure. "We have identified a key protein that acts together with a family of molecular switches to turn on cholesterol and fat (or lipid) production," says principal investigator Anders N??r, PhD, assistant professor of cell biology at Harvard Medical School and the Massachusetts General Hospital Can...

Marijuana Use Can Compromise Pregnancy

...ug among women of childbearing age. In the body it acts by binding to two receptors, called cannabinoid receptors 1 and 2 (CB1 and 2). These are the receptors found in the brain as well as in sperm, eggs and newly formed embryos.In normal conditions the two receptors are activated by a signaling molecule ...

New Tool to Watch Real-Time Chemical Activity in Cells

...t tells if a particular enzyme - called PKA - that acts like a “switch” is “on” or “off” in a living cell. The group has been focused on trying to understand and interfere with this enzyme switch, because if the enzyme is turned on at the wrong time or at the wrong place within cells, it can lead to cells...

Protein's Role in Triggering Cancer Identified

... Research UK, said: 'p53 is a crucial protein that acts as a guardian of the normal cell. Its failure to do its job properly is associated with many types of cancer. If p53 is being destroyed by another protein in a cancer cell, then it offers an excellent target when designing new anti-cancer drugs. This...

Scientists Unravel the Mystery behind Calbindin-D28K Protein

...brain. Recent studies show, Cavanagh says, that it acts as a bodyguard in the brain, binding to and inhibiting caspase-3, a protein that stimulates plaque formation and tangle formation, which are hallmark characteristics of neurodegenerative disease. Until now, however, the structure of calbindin-D28K...

Experiments In Outer Space To Determine single Cell Survival

...cell and the surrounding silica nanostructure, but acts as a template helping to direct the formation of the surrounding silica nanostructure. This improved architecture seamlessly retains water, needed by the cell to stay alive. Further, by eliminating stresses ordinarily caused by drying, the nanostru...

Treatment of Spinal Cord Injury with Embryonic Stem Cells

...ese cells are the building blocks of myelin, which acts as insulation for nerve fibers and is critical for maintenance of electrical conduction in the central nervous system. When myelin is stripped away through disease or injury, paralysis can occur. In this study, as in the original one, when the rats...

Heart disease and strokes connected to a motor protein mechanism

...mechanism used by an important motor protein which acts as a catalyst that enables bacteria outside the human body to travel through the blood stream and infect organs such as the heart. The findings were published by Rutgers-Newark Chemistry Assistant Professor Charalampos Kalodimos and his coworkers, ...

Researchers Use Bubbles in Cancer Treatment and Drug Delivery

...hem with high intensity ultrasound. The ultrasound acts like a pin popping a water balloon. After the shell pops, the perfluorocarbon expands into a gas bubble that is approximately 125 times larger in volume than the droplet. "If a bubble remained spherical its diameter would be much larger than that ...

Protein Behind Food Allergies Identified

...n normally present in a person's intestinal tract, acts as a receptor for IgE, a protein associated with allergic reactions. The researchers studied nine paediatric patients aged three to 17 years. They believe that the presence of CD23 may provide a surrogate method of looking at the gut without invasi...

Serotonin the Answer for Anti-Obesity Treatment

...ons, or POMC, which in turn release a hormone that acts on the MC4R to reduce appetite. The team's new study shows how serotonin also simultaneously blocks other neurons, known as NPY/AgRP, from being able to inhibit activity of MC4Rs. By blocking this inhibitory activity, serotonin prevents an increase i...

Study Finds That Brain Areas Of People With Autism Do Not Work In Coordination

...of corpus callosum, which is the white matter that acts as a cables to wire the various parts of the brain together. The new research shows for the first time has shown that the abnormality in synchronization is related to the abnormality in the cabling. Which could suggests that the connectivity among br...

Common Chemical From Seaweed Could Help In The Fight Against Cervical Cancer Virus-HPV

... and food stuffs. They explained that HPV normally acts by attacking the cells by attaching themselves to the proteins present on the cell surfaces and then chemically gaining access to the cells. They further explained that the carrageenan prevented infection by stopping the virus from attaching to the c...

Genital Herpes - No Symptoms But A Potent Carrier

...evented by the use of condoms. Even though condoms acts as a barrier in reducing the risk of spreading the disease it can still spread if the condoms do not cover the sores present in that area. Although there are certain medications to control the outbreaks of the disease there no such curing method st...

BJP Seeks Tougher Laws Against Pre-Natal Sex Tests

...f their gender and doctors who assist them in such acts should be treated as murderers. There should be tougher laws against both pre-natal sex detection and female foeticide," Singh, who also underscored the need for a social campaign against the practice, remarked. In her address, party leader Sushma S...

Researchers Try Early Surgical Intervention to Treat Parkinson's Symptoms

...p within the brain. When activated, the DBS device acts on the subthalamic nucleus with electrical stimulation to reduce the symptoms of Parkinson's. In many patients the device produces dramatic results. Charles and other researchers in Vanderbilt's Departments of Neurology and Neurosurgery have devote...
