New Calcitonin drug delivery research holds promise for osteoporosis sufferers

Calcitonin, a hormone that lowers calcium levels in the blood and prevents bone loss, has only been available in an injectable and nasally-administered format to date.

Environment factors can interact with genetics to increase disease risk

New research shows that exposure to harmful chemicals and drugs during critical developmental periods early in life may actually "reprogram" the way certain genes respond to the female hormone estrogen. This genetic reprogramming may determine whether people with a genetic predisposition for a disease actually develop the disease.

Long-haul flights, length of time under anesthesia increase risk of developing blood clots

The prolonged immobility of flight passengers during long-haul air travel increases the risk of developing blood clots, which could prove fatal especially to people whose travel occurs just prior to major surgery, medical researchers report in the current issue of Mayo Clinic Proceedings.

Is there a link between cell phones and brain tumors?

Is there a link between cell phones and brain tumors? Over the past 15 years, there has been growing concern about this possibility. Part of this concern stems from the fact that there are over one billion cell phone subscribers worldwide, and the number is increasing.

New approach to inhibiting blood vessel growth or angiogenesis

A manmade protein with a tail of amino acids delivered to target cells can dramatically reduce blood vessel growth that obstructs vision or feeds a tumor, researchers have found.

Those old crooners were right, love really can make you crazy

According to scientists brain images show that falling in love can look for all the world like mental illness with a mixture of mania, dementia and obsession that cuts people off from friends and family prompting uncharacteristic behavior which could almost be mistaken for psychosis.

Blood abnormality, sickle cell trait, gives added protection to children from malaria

The blood cell abnormality, sickle cell trait, gives an increasing amount of protection against malaria as young children grow during their first ten years of life, new research has revealed.

Exposure to pharmaceutical estrogen during fetal development can permanently "reprogram" tissue in a way that determines whether tumors will develop in adulthood

Researchers at The University of Texas M. D. Anderson Cancer Center may have uncovered the reason why some people who are genetically predisposed to hormone-dependent cancers develop the disease as an adult, while others who are similarly susceptible don't.

New gene shows way for autoimmune disease

A new gene suspected to contribute to autoimmune diseases such as type 1 diabetes and lupus - a condition in which the body’s own immune system attacks organs such as the kidneys and skin - has been discovered by Australian National University (ANU) immunologists.

Latest patterns of medication use in the U.S.

In 2004, 82 percent of adults and more than 50 percent of children took at least one prescription, over-the-counter (OTC), or herbal/natural medication in any given week, Boston University researchers revealed recently.

Research will benefit inhaler-users

Patients suffering from conditions as diverse as asthma and diabetes could benefit from research at Cardiff University to improve the effectiveness of drugs taken through spray inhalers.

New finding in studying dopamine transporter

Confirming findings in a previous study, Yale researchers observed an altered availability of the dopamine transporter in healthy persons with a genetic variation linked to substance abuse and attention deficit hyperactivity disorder (ADHD).

Chemicals in food packaging linked to breast cancer

Chemicals found in some food packaging materials have been shown in a new study to affect the development of breast tissue in mice, which suggests, say scientists, that women exposed to such chemicals, which mimic female hormones, may be at increased risk of breast cancer.

Fizzy drinks are the main source of calories in the U.S.

Tufts researchers recently reported that while the leading source of calories in the average American diet used to be from white bread, that may have changed.

Whole-body positron emission tomography/computed tomography scans may help physicians identify malignant cancerous tumors

A team of researchers at Johns Hopkins Medical Institutions in Baltimore, Md., reports that whole-body positron emission tomography/computed tomography (PET/CT) scans may help physicians identify new, unexpected malignant cancerous tumors in patients, according to an article in the May issue of the Society of Nuclear Medicine’s Journal of Nuclear Medicine.

Adolescent depression can be as high as 20 percent

Teenage depression is widespread and can become a life-long illness, but is more often transitory, said UCLA Psychology Professor Constance Hammen, who discussed her research at the American Psychological Society's annual convention in Los Angeles.

Discovery may lead to therapies to treat the neurological disease

Opening a window to understand the molecular basis of a hereditary ataxia, Dartmouth Medical School researchers have identified an enzyme activity that is inactivated in all reported mutant forms of a disease protein. The discovery may lead to therapies to treat the neurological disease.

A new technique might allow women diagnosed with cancer the opportunity to have children when chemotherapy and radiation treatments rob them of their fertility

Freezing eggs is one thing; thawing them safely so they can lead to pregnancy is the challenge. In the past, efforts to freeze a woman's eggs, or oocytes, have not worked well because the cells are large. When the egg is thawed, ice crystals cause damage that prevents the egg from being fertilized.

One in five patients hospitalized for heart attack experiences a major depression

According to the Hopkins cardiologists who conducted the study, these depressed patients are 50 percent more likely than other heart attack patients to need hospital care for a heart problem again within a year and three times as likely to die from a future attack or other heart-related conditions.

How the human brain can learn without thinking

Watch out -- you may learn something and not even know it, says Takeo Watanabe, an associate professor of psychology at Boston University's Center for Brain and Memory. Watanabe and his team recently pinpointed the mechanism that makes subliminal learning work. Watanabe will present the team's findings at the American Psychological Society meeting in Los Angeles, May 27 and 28.
