Mice have different neural subsystem associated with instinctually important smells

A new study finds that mice have a distinct neural subsystem that links the nose to the brain and is associated with instinctually important smells such as those emitted by predators. That insight, published online this week in Proceedings of the National Academy of Sciences, prompts the question whether mice and other mammals have specially hardwired neural circuitry to trigger instinctive behavior in response to certain smells.

Giving patients a new immune system can cure Crohn's disease

Researchers at Fred Hutchinson Cancer Research Center have opened a clinical trial to test the theory that giving a patient a new immune system can cure severe cases of Crohn's disease, a chronic inflammatory condition of the gastrointestinal tract.

RhoC gene promotes breast cancer stem cell progression

Researchers at the University of Michigan Comprehensive Cancer Center have found that a cancer gene linked to aggressive spread of the disease promotes breast cancer stem cells. The finding implies a new way to target the behavior of these lethal cells.

Moderate-to-severe TBI can disrupt proteins that regulate enzyme associated with Alzheimer's

A study, performed in mice and utilizing post-mortem samples of brains from patients with Alzheimer's disease, found that a single event of a moderate-to-severe traumatic brain injury (TBI) can disrupt proteins that regulate an enzyme associated with Alzheimer's.

Vanderbilt researchers receives new $2.1M grant to develop microbrain bioreactor

Take a millionth of a human brain and squeeze it into a special chamber the size of a mustard seed. Link it to a second chamber filled with cerebral spinal fluid and thread both of them with artificial blood vessels in order to create a microenvironment that makes the neurons and other brain cells behave as if they were in a living brain. Then surround the chambers with a battery of sensors that monitor how the cells respond when exposed to minute quantities of dietary toxins, disease organisms or new drugs under development.

Deep look into how brain mechanisms for memory retrieval differ between adults and children

Neuroscientists from Wayne State University and the Massachusetts Institute of Technology (MIT) are taking a deeper look into how the brain mechanisms for memory retrieval differ between adults and children.

New algorithm can help scientists predict gene and drug interactions

Researchers from Mount Sinai School of Medicine have developed a new computational method that will make it easier for scientists to identify and prioritize genes, drug targets, and strategies for repositioning drugs that are already on the market. By mining large datasets more simply and efficiently, researchers will be able to better understand gene-gene, protein-protein, and drug/side-effect interactions. The new algorithm will also help scientists identify fellow researchers with whom they can collaborate.

Insight into possible new approaches in vaccine development for blood-borne infections and HIV

White blood cells called neutrophils, which are the first line of defense against infection, play an unexpected role by boosting antibody production, according to research led by Mount Sinai School of Medicine. The findings suggest neutrophils have multiple roles within the immune system and function at levels previously unknown to the scientific community. The research, published in Nature Immunology, provides groundbreaking insight into possible new approaches in vaccine development for blood-borne infections and HIV.

New classification scheme for psychiatric symptoms

The traditional approach to psychiatric diagnosis is based on grouping patients on the basis of symptom clusters. This approach to diagnosis has a number of problems, as symptoms are not necessarily specific to a single diagnosis.

New large animal model for human cancer studies

A naturally occurring line of immunodeficient pigs can support the growth of human tumors injected under their skin, offering a promising new large animal model for studying human cancers and testing new drugs and treatment strategies.

Study identifies MDM4 protein as promising target for treatment of melanoma

A melanoma is a malignant form of skin cancer and is one of the most aggressive types of tumors there is. Treatment is particularly difficult, because melanomas are usually resistant against conventional chemotherapy treatments.

Biokine receives FDA Orphan Drug designation for BKT140 to treat hematological cancers

Biokine Therapeutics Ltd. announced today that it has received Orphan Drug designation from the US Food and Drug Administration (FDA) for the mobilization of hematopoietic stem cells from bone marrow into peripheral blood for collection and subsequent transplantation in patients with hematological cancers.

Mephedrone does have potential for abuse and addiction

The use of the synthetic stimulants collectively known as "bath salts" have gained popularity among recreational drug users over the last five years, largely because they were readily available and unrestricted via the Internet and at convenience stores, and were virtually unregulated.

Tumor necrosis factor may play a key role in how light at night leads to depression

Chronic exposure to dim light at night can lead to depressive symptoms in rodents -- but these negative effects can be reversed simply by returning to a standard light-dark cycle, a new study suggests.

Pancreatic cancer risk may be lowered by high dietary antioxidant intake

Increasing dietary intake of the antioxidant vitamins C, E, and selenium could help cut the risk of developing pancreatic cancer by up to two thirds, suggests research published online in the journal Gut.

Researchers identify new class of compounds that inhibit spread of prions

A team of University of Alberta researchers has identified a new class of compounds that inhibit the spread of prions, misfolded proteins in the brain that trigger lethal neurodegenerative diseases in humans and animals.

UV induction of melanin is directly involved in melanoma formation

A new study conducted by GW School of Medicine and Health Sciences (SMHS) researchers Edward C. De Fabo, Ph.D., Frances P. Noonan, Ph.D., and Anastas Popratiloff, M.D., Ph.D., has been published in the journal Nature Communications. Their paper, entitled "Melanoma induction by ultraviolet A but not ultraviolet B radiation requires melanin pigment," was published in June 2012.
