Study reveals why development of HIV treatments has been difficult

A new research report appearing in the March 2012 issue of the journal Genetics shows why the development of a cure and new treatments for HIV has been so difficult. In the report, an Australian scientist explains how he used computer simulations to discover that a population starting from a single human immunodeficiency virus can evolve fast enough to escape immune defenses.

Warming climate may increase risk from Chagas disease

In the spring of 1835, Charles Darwin was bitten in Argentina by a "great wingless black bug," he wrote in his diary. "It is most disgusting to feel soft wingless insects, about an inch long, crawling over one's body," Darwin wrote, "before sucking they are quite thin, but afterwards round & bloated with blood."

PCP signaling restricts neural growth during regeneration, homeostasis and development

The genetic pathway that regulates the way cells align themselves relative to each other has been found to act as a "stop sign" that signals organisms when to halt cell growth, according to new research published by biologists at the Center for Regenerative and Developmental Biology in Tufts University's School of Arts and Sciences.

Epigenetic designer baby may prove to be a non-starter

Epigenetics is the new hip science. Time Magazine's front cover and article, 'Why your DNA isn't your Destiny' from January 2010 explains why. Its more explicit subtitle provided the hook - 'The new science of epigenetics reveals how the choices you make can change your genes - and those of your kids'. Who wouldn't be interested in this?

Novel sensor selectively screens single molecules passing through nanopores

A novel type of sensor, based on nanometer-scale pores in a semiconductor membrane, is a step closer to practical use in applications such as analyzing the protein contents of a single cell. Researchers pioneering single-molecule nanopore sensor technology at the Technische Universit-t M-nchen (TUM) have shown its potential through a succession of experiments over the past few years.

CCN1 protein orchestrates cellular antiviral response in the extracellular matrix

Brain-tumor cells that are infected with a cancer-killing virus release a protein "alarm bell" that warns other tumor cells of the impending infection and enables them to mount a defense against the virus, according to a study led by researchers at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute.

Experts highlight latest advances in use of biomarkers in various diseases

Over the last few decades there has been an explosion in the discovery of biomarkers for diagnosis, disease monitoring, and prognostic evaluation. In the April issue of Translational Research, entitled "Biomarkers: New Tools of Modern Medicine," an international group of medical experts explores the promise and challenges of biomarker discovery and highlights the latest advances in the use of biomarkers in various diseases.

Positive correlation between working memory and mind wandering

Odds are, you're not going to make it all the way through this article without thinking about something else. In fact, studies have found that our minds are wandering half the time, drifting off to thoughts unrelated to what we're doing - did I remember to turn off the light? What should I have for dinner? A new study investigating the mental processes underlying a wandering mind reports a role for working memory, a sort of a mental workspace that allows you to juggle multiple thoughts simultaneously.

CYFRA reliable marker for response to chemotherapy for NSCLC

Researchers found that CYFRA and change in levels of CYFRA were found to be reliable markers for response to chemotherapy for non-small cell lung cancer (NSCLC) in a study of 88 patients. Research presented in the April 2012 issue of the International Association for the Study of Lung Cancer's (IASLC) Journal of Thoracic Oncology shows that this marker can be used to determine whether or not a patient should continue a particular chemotherapy regimen.

Neuropeptide F in the fly's brain governs behavior linked with addiction

Sexually deprived male fruit flies exhibit a pattern of behavior that seems ripped from the pages of a sad-sack Raymond Carver story: when female fruit flies reject their sexual advances, the males are driven to excessive alcohol consumption, drinking far more than comparable, sexually satisfied male flies.

Third International Symposium on Thymosins in Health and Disease to take place on GW campus

The George Washington University is host to the world's leaders in the area of research that focuses on Thymosins- small proteins present in many animal tissues that have diverse biological activities- Two in particular, thymosins α1 and β4, have potentially important uses in medicine, and research has already progressed from the laboratory to the clinic.

GABA neurons could help restore muscle coordination deficits of Huntington's

Huntington's disease, the debilitating congenital neurological disorder that progressively robs patients of muscle coordination and cognitive ability, is a condition without effective treatment, a slow death sentence. But if researchers can build on new research reported this week in the journal Cell Stem Cell, a special type of brain cell forged from stem cells could help restore the muscle coordination deficits that cause the uncontrollable spasms characteristic of the disease.

OHRI, uOttawa to lead first stem cell therapy trial for septic shock

A team of researchers from the Ottawa Hospital Research Institute (OHRI) and the University of Ottawa (uOttawa) has been awarded $367,000 from the Canadian Institutes of Health Research (CIHR) and $75,000 from the Stem Cell Network to lead the first clinical trial in the world of a stem cell therapy for septic shock.

Panel of 10 serum protein biomarkers could help in lung cancer diagnosis

A panel of serum biomarkers could help predict the level of lung cancer risk in high-risk patients, offering doctors an option before proceeding with a biopsy. Research presented in the April 2012 issue of the International Association for the Study of Lung Cancer's (IASLC) Journal of Thoracic Oncology shows that a panel of 10 serum protein biomarkers could help in the lung cancer diagnosis.

Combination therapy may improve life span and motor function of infants with Batten disease

Infants with Batten disease, a rare but fatal neurological disorder, appear healthy at birth. But within a few short years, the illness takes a heavy toll, leaving children blind, speechless and paralyzed. Most die by age 5.
