Hedione scent generates sex-specific activation patterns in brain

The question if humans can communicate via pheromones in the same way as animals is under debate. Cell physiologists at the Ruhr-Universität Bochum have demonstrated that the odorous substance Hedione activates the putative pheromone receptor VN1R1, which occurs in the human olfactory epithelium.

New, cross-sector collaboration aims to discover clinical biomarker for pancreatic cancer

The search to discover and validate the first-ever clinical biomarker to diagnose and treat pancreatic cancer is at the foundation of a new, cross-sector collaboration. Berg, a biopharmaceutical company committed to uncovering health solutions through a data-driven, biological research approach; the Cancer Center at Beth Israel Deaconess Medical Center, a Harvard Medical School teaching hospital, and the Pancreatic Cancer Research Team managed by Cancer Research And Biostatistics announced today they will work together to eradicate the disease.

Arts and craft activities, computer use may stave off memory problems

People who participate in arts and craft activities and who socialize in middle and old age may delay the development in very old age of the thinking and memory problems that often lead to dementia, according to a new study published in the April 8, 2015, online issue of Neurology, the medical journal of the American Academy of Neurology.

Study suggests that pancreatic cancers harbor genetic alterations

A genetic analysis led by UT Southwestern Medical Center researchers suggests that most pancreatic cancers harbor genetic alterations that could be targeted by existing drugs, using their genetic features as a roadmap for treatment. The findings support a precision approach to treating pancreatic cancer, the fourth most deadly cancer for both men and women.

UAB scientists create alternative to the use of viruses in gene therapy

A team of scientists from the Institute for Biotechnology and Biomedicine at the UAB has produced an alternative to the use of viruses in gene therapy. The researchers synthesised nanoparticles which act as artificial viruses, capable of surrounding DNA fragments and releasing them as therapeutic agents, with no biological risk, into the interior of the cells.

Simple dietary intervention can help reduce weight gain

A University of Calgary study has found that rats fed a fibre supplement while on a high fat and high sugar diet show a much lower weight gain than those who did not eat the fibre. A team of researchers from the university's Cumming School of Medicine and the Faculty of Kinesiology says the study helps scientists better understand the mechanisms of weight control and energy balance.

Clearer understanding of ORC offers new insight into fundamental DNA replication initiation mechanisms

A clearer understanding of the origin recognition complex (ORC) - a protein complex that directs DNA replication - through its crystal structure offers new insight into fundamental mechanisms of DNA replication initiation. This will also provide insight into how ORC may be compromised in a subset of patients with Meier-Gorlin syndrome, a form of dwarfism in humans.
