The neurobiology of music perception and production related to the pathways affecting intrinsic attachment behavior?

Music is social communication between individuals - humming of lullabies attach infant to parent and singing or playing music adds croup cohesion. The neurobiology of music perception and production is likely to be related to the pathways affecting intrinsic attachment behavior, suggests a resent Finnish study. The study gives new information about genetic background of musical aptitude.

New mouse model provides insight into human neuronal diseases

Neurosensory diseases are difficult to model in mice because their symptoms are complex and diverse. The genetic causes identified are often lethal when transferred to a mouse.

Discovery of genetic factors that influence the age at which natural menopause occurs in women

For the first time, scientists have been able to identify genetic factors that influence the age at which natural menopause occurs in women. Ms Lisette Stolk, a researcher from Erasmus MC, Rotterdam, The Netherlands, told the annual conference of the European Society of Human Genetics today ( Monday 25 May) that a greater understanding of the factors influencing age at menopause might eventually help to improve the clinical treatment of infertile women.

Discovery of genetic link between periodontitis and heart attack

The relationship between the dental disease periodontitis and coronary heart disease (CHD) has been known for several years. Although a genetic link seemed likely, until now its existence was uncertain. Now, for the first time, scientists have discovered a genetic relationship between the two conditions, a researcher told the annual conference of the European Society of Human Genetics today (Monday 25 May).

Nervous system may be culprit in Pompe disease

Brain may win out over brawn as the primary cause of breathing problems in children with a severe form of muscular dystrophy known as Pompe disease.

Inositol protects against the development of neural tube defects

Women of childbearing age can reduce the risk of having a child born with a neural tube defect such as spina bifida by eating enough folate or folic acid. However, folate prevents only about 70 percent of these defects.

Inflammation clue to fragile bones in Duchenne's muscular dystrophy

Inflammation could contribute to bone loss in Duchenne's muscular dystrophy (DMD), a discovery made by a group of Italian researchers. Dr Anna Rufo and her colleagues found that levels of an inflammatory molecule, known as IL-6, are high in patients with DMD.

Scientists cure mice of muscle disease that causes a Floppy Baby Syndrome

In a world first, West Australian scientists have cured mice of a devastating muscle disease that causes a Floppy Baby Syndrome - a breakthrough that could ultimately help thousands of families across the globe.

Heart protein saves muscle

A heart muscle protein can replace its missing skeletal muscle counterpart to give mice with myopathy a long and active life, show Nowak et al. The findings will be published online on Monday, May 25, 2009 and will appear in the June 1, 2009 print issue of the Journal of Cell Biology.

Cancer drugs erlotinib and gefitinib might treat alcoholism

A class of drugs already approved as cancer treatments might also help to beat alcohol addiction. That's the conclusion of a discovery in flies of a gene, dubbed happyhour, that has an important and previously unknown role in controlling the insects' response to alcohol.

Simple genetic test determines transplant drug tolerance

A simple genetic test can determine a kidney transplant patient's tolerance for a potent anti-rejection medication, according to an upcoming study in the Journal of the American Society Nephrology (JASN). The test could allow doctors to individualize each patient's dose, optimizing the drug's benefits and minimizing its side effects.

Discovery of gene that controls sugar production, implications for diabetes

Scientists in Sydney and Boston believe they may have identified a gene that controls abnormal production of sugar in the liver, a very troublesome problem for people with diabetes.

Genetic testing for breast or ovarian cancer risk may be greatly underutilized

Although a test for gene mutations known to significantly increase the risk of hereditary breast or ovarian cancer has been available for more than a decade, a new study finds that few women with family histories of these cancers are even discussing genetic testing with their physicians or other health care providers.

Researchers discuss combined approach to maximize benefits and minimize risks of stem cell therapy

Once placed into a patient's body, stem cells intended to treat or cure a disease could end up wreaking havoc simply because they are no longer under the control of the clinician.

Getting more from whole-transcript microarrays

The widely-used Affymetrix Whole-Transcript Gene 1.0 ST (sense target) microarray platform, normally used to assay gene expression, can also be utilized to interrogate exon-specific splicing. Research published today in the open access journal BMC Bioinformatics shows scientists how to monitor alternative splicing activity on a genome-wide scale, without investing in new exon microarray technologies.

Novel method stimulates growth of new neurons in adult brain

University at Buffalo researchers have identified a new mechanism that plays a central role in adult brain stem cell development and prompts brain stem cells to differentiate into neurons.

New insights into a new strain of chlamydia

New sequencing and analysis of six strains Chlamydia will result in improved diagnosis of the sexually transmitted infection. This study provides remarkable insights into a new strain of Chlamydia that was identified in Sweden in 2006 after spreading rapidly across the country by evading most established diagnostic tests.

People with Down syndrome may have more cancer-protective genes

Most cancers are rare in people with Down syndrome, whose overall cancer mortality is below 10 percent of that in the general population. Since they have an extra copy of chromosome 21, it's been proposed that people with Down syndrome may be getting an extra dose of one or more cancer-protective genes.

Junk DNA may not be so ‘junky’ after all

Scientists have called it "junk DNA." They have long been perplexed by these extensive strands of genetic material that dominate the genome but seem to lack specific functions. Why would nature force the genome to carry so much excess baggage?

Nanoparticles used to stimulate growth of new neurons in adult brain

University at Buffalo researchers have identified a new mechanism that plays a central role in adult brain stem cell development and prompts brain stem cells to differentiate into neurons.
