Scientists restore sense of smell in mice through gene therapy

Scientists have restored the sense of smell in mice through gene therapy for the first time -- a hopeful sign for people who can't smell anything from birth or lose it due to disease.

DEAD-box proteins function as recycling nanopistons when unwinding RNA

AUSTIN, Texas-Molecular biologists at The University of Texas at Austin have solved one of the mysteries of how double-stranded RNA is remodeled inside cells in both their normal and disease states. The discovery may have implications for treating cancer and viruses in humans.

Digested coconut oil able to attack the bacteria that cause tooth decay

Digested coconut oil is able to attack the bacteria that cause tooth decay. It is a natural antibiotic that could be incorporated into commercial dental care products, say scientists presenting their work at the Society for General Microbiology's Autumn Conference at the University of Warwick.

Potential new COPD drug

A study led by researchers at Boston University School of Medicine (BUSM) has shown that a compound used in some skin creams may halt the progression of emphysema and reverse some of the damage caused by the disease. When the compound Gly-His-Lys (GHK) was applied to lung cells from patients with emphysema, normal gene activity in altered cells was restored and damaged aspects of cellular function were repaired.

New intriguing knowledge on blood haemoglobin

Scientists at the research centre MEMBRANES at Aarhus University, Denmark, have completed an old puzzle, which since the 60s from many sides has been regarded as impossible to complete. The challenge was to solve the structure of the protecting protein complex that forms when haemoglobin is released from red cells and becomes toxic. This toxic release of haemoglobin occurs in many diseases affecting red cell stability, e.g. malaria.

Scientists show how pluripotent stem cells mobilize in wounded planarian worms

The skin, the blood, and the lining of the gut-adult stem cells replenish them daily. But stem cells really show off their healing powers in planarians, humble flatworms fabled for their ability to rebuild any missing body part. Just how adult stem cells build the right tissues at the right times and places has remained largely unanswered.

Dysfunctional RyRs play a role in stress-induced cognitive dysfunction

ARMGO Pharma, Inc., a biopharmaceutical company developing innovative small molecule drugs known as "Rycals™," which act on the ryanodine receptor calcium-release channel (RyR), announced that a study published today in the prestigious scientific journal Cell reveals the underlying role of calcium leak through the RyR as an important contributor to stress-induced cognitive dysfunction.

Scientists identify specific role of RESA protein in modulating blood circulation

When the parasite responsible for malaria infects human red blood cells, it launches a 48-hour remodeling of the host cells. During the first 24 hours of this cycle, a protein called RESA undertakes the first step of renovation: enhancing the stiffness of the cell membranes.

Study explains why some cancer vaccines are not as effective as hoped

A research report published in the September 2012 issue of the Journal of Leukocyte Biology offers a possible explanation of why some cancer vaccines are not as effective as hoped, while at the same time identifies a new therapeutic strategy for treating autoimmune problems. In the report, scientists suggest that cancer, even in the very early stages, produces a negative immune response from dendritic cells, which prevent lymphocytes from working against the disease.

New research about brain and related disorders to be unveiled at Neuroscience 2012

New research about the brain and related disorders will be unveiled at Neuroscience 2012 in New Orleans, Oct. 13-17. Findings will include how the brain weighs complex decisions; progress being made in treating Alzheimer's disease, spinal cord injury, and traumatic brain injury; and novel understanding of how life experiences, diet, and sleep influence brain health and wellness.

S107 drug can prevent learning and memory deficits associated with stress-related disorders

Columbia University Medical Center (CUMC) researchers have identified a potential medical treatment for the cognitive effects of stress-related disorders, including post-traumatic stress disorder (PTSD).

Viewpoints: Romney, Ryan rely on 'the magic asterisk'; Frightening voters over Medicare cuts

The press has focused a lot on the similarities between Mitt Romney and Paul Ryan. They are both technocratic, they espouse tax cuts, and they believe in a balanced budget. But there is a deeper similarity as well: they both believe deeply in the "magic asterisk." The magic asterisk was the invention of David Stockman, budget director to Ronald Reagan. Stockman, who needed to show a more favorable budget than the Reagan tax cuts would justify, put in an asterisk and noted "future savings to be identified."

Brazil expanding national HIV treatment program to include patients with higher CD4 cell counts

Brazil is expanding its national HIV/AIDS treatment program to include about 35,000 additional people, the Associated Press/Seattle Times reports. "Ronaldo Hallal of the health ministry's Sexually Transmitted Disease Department said people with 500 or fewer CD4 cells per cubic millimeter will receive antiretroviral HIV treatment," increasing the cutoff from 350 or less CD4 cells per cubic millimeter prior to the expansion, the news service writes.

Glaucoma and cell death: an interview with Dr. Vivek Gupta

Glaucoma is normally caused by increased pressure of aqueous humour fluid in the eye. A defining feature of this disease is destruction of a particular type of cells in the retina called retinal ganglion cells and excavation of the optic disc region.

Researchers discover new immune response mechanism during infection

Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered a new "first response" mechanism that the immune system uses to respond to infection. The findings challenge the current understanding of immunity and could lead to new strategies for boosting effectiveness of all vaccines. The study, conducted in mice, published online today in the journal Immunity.
