The human brain is the center of the human nervous system and is a highly complex organ. Enclosed in the cranium, it has the same general structure as the brains of other mammals, but is over three times as large as the brain of a typical mammal with an equivalent body size.

Alzheimer's and diabetes link

Diabetic individuals have a significantly higher risk of developing Alzheimer's disease but the molecular connection between the two remains unexplained. Now, researchers at the Salk Institute for Biological Studies identified the probable molecular basis for the diabetes - Alzheimer's interaction.

Medicare costs estimated at $21.1 billion for 5 years of care for elderly cancer patients

The cost of cancer care for elderly Medicare patients varies by tumor type, stage at diagnosis, phase of care, and survival, according to a new study published online April 29 in the Journal of the National Cancer Institute.

Alcohol affects threat-detecting brain circuits

New brain imaging research published this week shows that, after consuming alcohol, social drinkers had decreased sensitivity in brain regions involved in detecting threats, and increased activity in brain regions involved in reward.

Gastric bypass surgery and effect on lower back pain

The prevalence of both obesity and back pain in developing nations has reached alarming levels. According to recent statistics, more than one-third of U.S. adults - over 72 million people were obese in 2005-2006. Of these, 33.3 percent were men and 35.3 percent were women. Especially alarming is that obesity has not decreased among teenagers - the rates remain essentially unchanged in 2005-2006 from the 2003-2004 estimates, at 17 percent.

Deep brain stimulation may help people with treatment resistant major depression

Researchers from the Cleveland Clinic, Brown University, and Massachusetts General Hospital will present results of a long-term outcome study that builds on previous promising research, which has shown that deep brain stimulation (DBS) is a potentially effective treatment option for people with treatment resistant major depression.

Brain tumor surgery, depression and survival

Depression is one of the most common psychiatric disorders in the world today. It is estimated that in any given year, 5 to 9 percent of the US population is clinically depressed. Studies have shown that depression negatively affects the immunological system, alters the body's response to malignancy, and may influence behavioral factors that impact recovery from disease

Effectiveness of decompression surgery in patients with cervical spinal cord injuries

Every year, nearly 12,000 individuals in the United States and Canada, mostly young adults, sustain a spinal cord injury (SCI). According to the Centers for Diseases Control and Prevention (CDC), SCI costs an estimated $9.7 billion each year in the United States alone.

Enterovirus 71 in Chinese province kills 20 children

A virus in China has which has killed 20 children and made 1,179 others ill is causing alarm.

Popular blood pressure drugs could hold the key to weight loss

A study by Australian scientists has indicated that some of the most commonly used blood pressure medications could help people lose weight and body fat and reduce the likelihood of them developing diabetes.

New research suggests hypertonic, hyperviscous fluids may be better treatment for severe blood loss

Intravenous administration of isotonic fluids is the standard emergency treatment in the U.S. for patients with severe blood loss, but UC San Diego bioengineering researchers have reported improved resuscitation with a radically different approach. Building on earlier studies in humans that have shown benefits of intravenous fluids that are eight times saltier than normal saline, the researchers combined hypertonic saline with viscosity enhancers that thicken blood.

Cell-based therapy shows promise in patients with Parkinson's disease

Rush University Medical Center neurosurgeon Dr. Roy A. E. Bakay and colleagues from Emory University, Atlanta found the therapy Spheramine was well-tolerated and patients experienced improvement in Parkinsonian symptoms (tremor, rigidity, slowness of movements, and impaired balance and coordination.)

Scientists find distinct kind of stem cells in the pituitary gland

A team of researchers led by scientists at Cold Spring Harbor Laboratory have for the first time identified stem cells that allow the pituitary glands of mice to grow even after birth.

New drug discovery tool for Alzheimer's disease

An article published in the April issue of the Journal of Alzheimer's Disease presents a detailed characterization of a new drug discovery tool for Alzheimer's disease.

Scientists discover way to increase metabolism for weight loss

Scientists from Melbourne's Howard Florey Institute have discovered a way to aid weight loss and reduce the likelihood of developing diabetes by manipulating fat cells to increase the body's metabolism.

Scientists explore brain's reaction to potent hallucinogen

Brain-imaging studies performed in animals at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory provide researchers with clues about why an increasingly popular recreational drug that causes hallucinations and motor-function impairment in humans is abused.

Sensory integration therapy helps children with autism

Parents of children with autism are increasingly turning to sensory integration treatment to help their children deal with the disorder, and they're seeing good results. In 2007, 71 percent of parents who pursued alternatives to traditional treatment used sensory integration methods, and 91 percent found these methods helpful.

Research links low-frequency hearing to shape of the cochlea

Shape matters, even in hearing. Specifically, it is the shape of the cochlea - the snail-shell-shaped organ in the inner ear that converts sound waves into nerve impulses that the brain deciphers - which proves to be surprisingly important.

Study looks at anesthetic desflurane and Alzheimer's

In studies of human brain cells, the widely-used anesthetic desflurane does not contribute to increased production of amyloid-beta protein; however, when combined with low oxygen conditions, it can produce more of this Alzheimer's associated protein.

3D view of neurons provided by new technique

A new technique that marries a fast-moving laser beam with a special microscope that look at tissues in different optical planes will enable scientists to get a three-dimensional view of neurons or nerve cells as they interact, said Baylor College of Medicine scientists in a report that appears in the journal Nature Neuroscience.
