Discovery of gene vital to early embryonic cells forming a normal heart and skull

New research from Cincinnati Children's Hospital Medical Center highlights the critical role a certain gene and its protein play during early embryonic development on formation of a normal heart and skull.

Cannabis smoke damages DNA – cancer risks

A new study published by University of Leicester researchers has found "convincing evidence" that cannabis smoke damages DNA in ways that could potentially increase the risk of cancer development in humans.

Histamine affects alcohol-related behaviour

The histamine-3 receptor is important in terms of alcohol-related behaviour, and a drug affecting that receptor may have qualities that alter alcohol-related behaviour.

Immune system’s role in breast cancer

Researchers working with Dr Marcus Schmidt in the Department of Obstetrics and Gynecology at the University Medical Center Mainz have unlocked the key to the immune system's significance in cases of breast cancer, thus identifying its long-neglected role in the prognosis of the disease.

Genomic discovery: Protecting kidney function during heart failure

Mayo Clinic cardiology researchers have found a peptide that helps preserve and improve kidney function during heart failure, without affecting blood pressure. Earlier variations of this peptide caused blood pressure to drop limiting the potential benefits to the kidneys. The findings appear in the current Proceedings of the National Academy of Sciences.

Cognitive shortcut causes people to miscalculate weight and caloric intake

Psychologists at the University of Pennsylvania have identified a cognitive shortcut, or heuristic, they call "Unit Bias," which causes people to ignore vital, obvious information in their decision-making process, points to a fundamental flaw in the modern, evolved mind and may also play a role in the American population's 30 years of weight gain.

New findings on how stress causes sexual dysfunction and infertility

University of California, Berkeley, researchers have found what they think is a critical and, until now, missing piece of the puzzle about how stress causes sexual dysfunction and infertility.

Skin disease psoriasis associated with cardiovascular disease and increased mortality

The skin disease psoriasis is associated with atherosclerosis (a buildup of plaque in the arteries) characterized by an increased prevalence of ischemic heart disease, cerebrovascular disease, peripheral artery disease and an increased risk of death, according to a report in the June issue of Archives of Dermatology.

Could hormones explain gender differences in neurological disease?

Neurological diseases including Parkinson's, Tourette's, attention deficit hyperactivity disorder (ADHD), Alzheimer's, and schizophrenia are all associated with alterations in dopamine-driven function involving the dopamine transporter (DAT).

RNA snippet reduces the spread of aggressive breast cancer

A low cellular level of a tiny fragment of RNA appears to increase the spread of breast cancer in mouse models of the disease, according to researchers at Whitehead Institute for Biomedical Research.

A novel and universal method for microRNA data analysis

Our understanding of the importance of microRNAs in regulating gene expression is expanding, and with it our requirement for robust methods to measure their expression levels. Now a new method published in BioMed Central's open access journal Genome Biology helps researchers to better understand the delicate interplay between differences in microRNA expression levels and their target genes.

Novel method directs and separates cancer cells from normal cells

The vast majority of cancer deaths are due to metastasis, the spread of cancer cells from its primary site to other parts of the body. These metastatic cells tend to move more than their non-metastatic variants but this movement is poorly understood. Scientists are studying cancer cells intently with the hope they can learn to control the movements of the dangerous cells.

New form of radiotherapy could revolutionize treatment for recurrent prostate cancer

A new study shows that an alpha-particle emitting radiopeptide - radioactive material bound to a synthetic peptide, a component of protein - is effective for treating prostate cancer in mice, according to researchers at SNM's 56th Annual Meeting in Toronto.

Inflammation of microglia may not be associated with dementia in Alzheimer's disease

The idea that anti-inflammatory drugs might protect people struggling with dementia from Alzheimer's disease has received a blow with the online release of a study of human brain tissue in Acta Neuropathologica.

Severe obesity brings greater risks of health problems during medical procedures

Healthcare providers must carefully consider the unique risk factors related to severe obesity in patients undergoing all types of surgery, according to an American Heart Association scientific advisory published in Circulation: Journal of the American Heart Association.

Non-toxic radioactive patch successfully treats skin cancer

A new study shows that a radioactive skin patch can safely and successfully treat basal cell carcinoma, one of the most common types of skin cancers, according to researchers at the SNM's 56th Annual Meeting. The skin patch, which delivers the radioactive phosphorus-32, is nontoxic and could be an excellent alternative to surgery or radiotherapy in cases where carrying out these treatments is difficult.

Positron emission tomography scans may improve the accuracy of dementia diagnosis

A new study shows that the use of positron emission tomography (PET) scans may improve the accuracy of dementia diagnoses early in disease onset for more than one out of four patients. The results were presented at SNM's 56th Annual Meeting.

Depression may increase risk of Alzheimer's disease in people with memory problems

People with memory problems who are depressed are more likely to develop Alzheimer's disease compared to people who are not depressed, according to a study published in the June 16, 2009, print issue of Neurology, the medical journal of the American Academy of Neurology. However, the research also shows that the popular Alzheimer's drug donepezil may delay the progression to Alzheimer's disease for depressed people with mild cognitive impairment (MCI) or memory problems.

Discovery in dendritic cell signalling pathways pave way for new therapeutic targets

Scientists from A*STAR's Singapore Immunology Network (SIgN) and the University of Milano-Bicocca, Italy, have discovered another signaling pathway for the activation and apoptosis, or programmed cell death, of dendritic cells. This discovery was published in the advanced online publication of Nature on 15 Jun 2009.

Cancer immunotherapy can use small numbers of ‘stem-like’ immune cells to destroy large tumors in mice

A new approach to stimulating immune cells enhances their anticancer activity, resulting in a powerful anti-tumor response in mice, according to a study by researchers at the National Cancer Institute, a part of the National Institutes of Health. This work represents an important advance in the development of immunotherapy for cancer and appears online June 14, 2009 in Nature Medicine.
