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.

Study represents new use of bone marrow transplantation

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.

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.

Scientists identify mechanisms by which GLP-1 protects against kidney disease, diabetes

Scientists at Joslin Diabetes Center have identified biological mechanisms by which glucagon-like peptide-1 (GLP-1), a gut hormone, protects against kidney disease, and also mechanisms that inhibit its actions in diabetes.

PAMAM G-3 actually prevents activation of the process that leads to thrombosis

A compound that mops up debris of damaged cells from the bloodstream may be the first in a new class of drugs designed to address one of medicine's most difficult challenges -- stopping the formation of blood clots without triggering equally threatening bleeding.

Scientists demonstrate link between cancer and faulty differentiation of stem cells

Stem cells hold great promise for the medicine of the future, but they can also be a cause of disease. When these self-renewing, unspecialized cells fail to differentiate into diverse cell types, they can start dividing uncontrollably, leading to cancer. Already several decades ago, Weizmann Institute scientists were among the first to demonstrate the link between cancer and the faulty differentiation of stem cells. Now a new Weizmann Institute-led study, published in Molecular Cell, reveals a potential molecular mechanism behind this link.
