NIBIB-funded researchers explore better treatment for brain aneurysms

Thirty thousand Americans suffer severe neurological damage or death from brain aneurysms each year and the existing treatments eventually fail in nearly half of patients. Currently, these "bubbles" in the blood vessel are either clamped off, which requires invasive brain surgery, or filled with platinum coils to induce clotting in the aneurysm. Both treatments, although somewhat effective, can have subsequent problems, including inflammation, incomplete healing, and the development of secondary aneurysms adjacent to the initial site. These complications result in approximately 40 percent of patients needing additional treatment to attempt to re-repair the aneurysm.

Researchers show benefits from testosterone administration in hysterectomized women

Hysterectomy and oophorectomy (the removal of ovaries) are performed to treat various diseases in women, including cancer. These procedures are accompanied not only by a decline in estrogen but also testosterone levels in the blood.

UCLA researchers identify cells involved in placenta development

Dr. Hanna Mikkola and researchers at UCLA's Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research have identified a specific type of cell and a related cell communication pathway that are key to the successful growth of a healthy placenta. The findings could greatly bolster our knowledge about the potential causes of complications during pregnancy.

Brain research provides new clues to Pavlovian conditioning

Do fruit flies hold the key to treating dementia? Researchers at the University of Houston have taken a significant step forward in unraveling the mechanisms of Pavlovian conditioning. Their work will help them understand how memories form and, ultimately, provide better treatments to improve memory in all ages.

Findings highlight possible new approach to combat malaria

An international team of scientists, including researchers at Columbia University Medical Center, has identified a key metabolic enzyme that common malaria parasites require for survival at each stage of infection in humans. The findings raise the possibility of a new approach to combating malaria, one of the world's deadliest diseases. The study was published today in the online edition of the journal Nature.

Implantable genetic circuit serves as early warning system for high blood-fat levels

Humankind has a weight problem - and not only in the industrialised nations, either: the growing prosperity in many Asian or Latin American countries goes hand in hand with a way of life that quite literally has hefty consequences.

Study uncovers mechanisms that allow stem cells to keep dividing in perpetuity

The blood stem cells that live in bone marrow are at the top of a complex family tree. Such stem cells split and divide down various pathways that ultimately produce red cells, white cells and platelets. These "daughter" cells must be produced at a rate of about one million per second to constantly replenish the body's blood supply.

Bioaxial secures funds to market optical microscopy modules

Bioaxial, developers of super-resolved fluorescence microscopy for the extended imaging of live cells, today announces the completion of a EUR 1.9 million (USD 2.7 million) equity investment by three new large investors; Amorcage Technologique Investissement (a fund managed by CEA Investissement), Inserm Transfert Initiative and Viveris Management plus a range of individual investors.

Research: Motor proteins transport mRNA to get where it is needed, prevent diseases

Scientists have found that mRNA may travel one way down a cell, then board another, aptly named motor protein, and head in the opposite direction to get where it ultimately needs to be.

Study reveals how brain and olfactory system operate to process scent, odor signals

Our sense of smell is often the first response to environmental stimuli. Odors trigger neurons in the brain that alert us to take action.

EPCs: A promising therapy for type 1 diabetes

Pancreatic islet transplantation is a promising therapy for treating type 1 diabetes, but the majority of transplanted cells die soon after they are transplanted.

Inhibition of complement system plays major role in xenograft rejection

Researchers at the Bellvitge Institute of Biomedical Research (IDIBELL) led by Cristina Costa from the New Therapies on Genes and Transplantation group have shown that inhibition of one of the basic components of the complement system protects chondrocytes (cartilage cells) from porcine rejection of xenotransplantation (transplantation between animals of different species).

Researchers show how unusual properties of A3G protein help fight HIV infection

A collaborative team led by a Northeastern University professor may have altered the way we look at drug development for HIV by uncovering some unusual properties of a human protein called APOBEC3G.

Protecting or boosting neurotrophins may slow progression of Huntington's disease

A drug that acts like a growth-promoting protein in the brain reduces degeneration and motor deficits associated with Huntington's disease in two mouse models of the disorder, according to a study appearing November 27 in the Journal of Neuroscience. The findings add to a growing body of evidence that protecting or boosting neurotrophins - the molecules that support the survival and function of nerve cells - may slow the progression of Huntington's disease and other neurodegenerative disorders.

Breakthrough discovery could lead to development of future therapeutics for prostate cancer

Drs. Andrew Goldstein, Owen Witte, and Tanya Stoyanova and their colleagues from UCLA's Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research have found that prostate cancer can develop in one type of stem cell, then evolve to be maintained by a stem cell that looks very different, making prostate cancer stem cells a "moving target" for treatments. The breakthrough discovery connects directly to the development of future therapeutics that target cancer and was published online ahead of print in the Proceedings of the National Academy of Sciences.

African Americans have double the risk of end-stage renal disease compared to white Americans

In the United States, African Americans have approximately twice the risk of end-stage renal disease compared to white Americans, despite a similar prevalence in earlier stages of chronic kidney disease. A large study co-authored by George Washington University researcher Dominic Raj, M.D., identifies factors that mediate differences in the progression of chronic kidney disease between black patients and white patients, as well as among black patients, in order to reduce the excess burden of end-stage renal disease and its complications in black patients.

Freiburg scientists discover substance that suppresses unchecked cell division in leukemia cells

Scientists of the University of Freiburg and the Freiburg University Medical Center from the collaborative research center Medical Epigenetics (SFB 992) have discovered a new active substance that inhibits cell division in leukemia cells and could play an important role in the fight against cancer.

CSHL identifies specific stretch of DNA that helps cancerous blood cells to proliferate in AML

A team of researchers at Cold Spring Harbor Laboratory (CSHL) has identified a leukemia-specific stretch of DNA called an enhancer element that enables cancerous blood cells to proliferate in Acute Myeloid Leukemia (AML), a devastating cancer that is incurable in 70% of patients.

EU-funded project develops new type of vaccine to tackle HIV virus infection

AIDS research has attempted many strategies to tackle the HIV virus infection. Now, a new type of vaccine developed within an EU-funded project, called EuroNeut-41, is based on one of the envelope proteins of the HIV virus, called the gp41 protein. What makes it interesting it that it is directly responsible for the fusion of the HIV virus into human cells. By integrating the gp41 protein into the vaccine, researchers try to trigger the production of antibodies that would block the entrance of HIV into human cells
