Odor receptors discovered in lungs: Just like ones in your nose but instead of conjuring up a cup of coffee they might make you cough Posted: 02 Jan 2014 12:23 PM PST Your nose is not the only organ in your body that can sense cigarette smoke wafting through the air. Scientists have showed that your lungs have odor receptors as well. The odor receptors in your lungs are in the membranes of flask-shaped neuroendocrine cells that dump neurotransmitters and neuropeptides when the receptors are stimulated, perhaps triggering you to cough to rid your body of the offending substance.

Patch outperforms Holter for prolonged heart rhythm tracking Posted: 02 Jan 2014 12:23 PM PST Researchers have discovered that a small adhesive wireless device worn on the chest for up to two weeks does a better job detecting abnormal and potentially dangerous heart rhythms than the Holter monitor, which is typically used for 24 hours and has been the standard of care for more than 50 years.

New technique enables patient with 'word blindness' to read again Posted: 02 Jan 2014 12:23 PM PST A novel technique has enabled a patient with "word blindness" to read again. Word blindness is a rare neurological condition. (The medical term is "alexia without agraphia.") Although a patient can write and understand the spoken word, the patient is unable to read.

Chinese herbal compound relieves inflammatory, neuropathic pain Posted: 02 Jan 2014 10:36 AM PST A compound derived from a traditional Chinese herbal medicine has been found effective at alleviating pain, pointing the way to a new nonaddictive analgesic for acute inflammatory and nerve pain, according to researchers.

Jumping DNA in brain may be cause of schizophrenia Posted: 02 Jan 2014 10:31 AM PST Stretches of DNA called retrotransposons, often dubbed "junk DNA", might play an important role in schizophrenia. In a study published, a Japanese team revealed that LINE-1 retrotransposons are abnormally abundant in the schizophrenia brain, modify the expression of genes related to schizophrenia during brain development, and may be one of the causes of schizophrenia.

Scientists uncover most detailed picture yet of muscular dystrophy defect then design targeted new drug candidates Posted: 02 Jan 2014 10:30 AM PST Scientists have revealed an atomic-level view of a genetic defect that causes a form of muscular dystrophy, myotonic dystrophy type 2, and have used this information to design drug candidates with potential to counter those defects—and reverse the disease.

Turning off 'aging genes' Posted: 02 Jan 2014 09:34 AM PST Restricting calorie consumption is one of the few proven ways to combat aging. Now researchers have developed a computer algorithm that predicts which genes can be "turned off" to create the same anti-aging effect as calorie restriction. The findings could lead to the development of new drugs to treat aging.

Study supports causal role in narcolepsy for common genetic variant Posted: 02 Jan 2014 08:31 AM PST A new study conducted across Europe found an extraordinary association between narcolepsy and a specific gene variant related to the immune system.

Cognitive-behavioural therapy not effective treatment for symptoms of schizophrenia Posted: 02 Jan 2014 08:22 AM PST Health organizations around the world recommend a form of psychotherapy, known as cognitive-behavioral therapy or CBT, for patients with schizophrenia. Now, however, the most extensive study ever undertaken into its effect on the symptoms of the disorder finds little impact, according to a team of international researchers.

Novel non-invasive therapy prevents breast cancer formation in mice Posted: 01 Jan 2014 01:19 PM PST A novel injectable therapy partially reverses cancer formation in cultured mammary-gland cells and prevents breast cancer development in mice, a team reports. The therapy silences a new cancer-causing gene that the scientists identified using a sophisticated systems biology approach. It could one day provide a new way to treat early stages of breast cancer without surgery, chemotherapy or radiation.

Study identifies factors associated with pain one year after breast cancer surgery Posted: 31 Dec 2013 01:39 PM PST In a study that included more than 800 women who had undergone surgery for breast cancer, the majority reported some level of pain 12 months after surgery, and factors associated with pain included chronic preoperative pain, chemotherapy, preoperative depression and pain in the area to be operated, according to a study.

Radiotherapy less often used by breast cancer patients with young children Posted: 24 Dec 2013 03:36 PM PST Radiotherapy (RT) after breast conserving surgery (BCS) has been shown to reduce the risk of breast cancer (BC) recurrence. However, although younger women tend to have more aggressive tumors and have higher risks of recurrence than older BC patients, they are less likely to receive RT after BCS, according to a study.

Common type of diabetes triples risk of an early menopause in women under 45 Posted: 20 Dec 2013 05:07 PM PST Type 2 diabetes - the most common type of diabetes - triples the risk of an early menopause in women younger than 45 years of age, according to new research.
