Leading Ebola researcher says there’s an effective treatment for Ebola

A leading U.S. Ebola researcher from the University of Texas Medical Branch at Galveston has gone on record stating that a blend of three monoclonal antibodies can completely protect monkeys against a lethal dose of Ebola virus up to 5 days after infection, at a time when the disease is severe. Thomas Geisbert, professor of microbiology and immunology, has written an editorial for Nature discussing advances in Ebola treatment research. Continue reading

Home is where the microbes are

Home is where the microbes are

A person’s home is their castle, and they populate it with their own subjects: millions and millions of bacteria. A study published tomorrow in Science provides a detailed analysis of the microbes that live in houses and apartments. Continue reading

Encyclopedia of how genomes function gets much bigger

Encyclopedia of how genomes function gets much bigger

A big step in understanding the mysteries of the human genome was unveiled today in the form of three analyses that provide the most detailed comparison yet of how the genomes of the fruit fly, roundworm, and human function. The research, appearing August 28 in in the journal Nature, compares how the information encoded in the three species’ genomes is “read out,” and how their DNA and proteins are organized into chromosomes. The results add billions of entries to a publicly available archive of functional genomic data Continue reading

Xenon exposure shown to erase traumatic memories

Xenon exposure shown to erase traumatic memories

McLean Hospital researchers are reporting that xenon gas, used in humans for anesthesia and diagnostic imaging, has the potential to be a treatment for post-traumatic stress disorder (PTSD) and other memory-related disorders. “In our study, we found that xenon gas has the capability of reducing memories of traumatic events,” said Edward G. Meloni, PhD, assistant psychologist at McLean Hospital and an assistant professor of Psychiatry at Harvard Medical School. Continue reading

Aspirin may reduce the risks of reoccurring blood clots

Aspirin may reduce the risks of reoccurring blood clots

Aspirin may be a promising alternative for those who can’t take long-term anticoagulant drugs that prevent clots from reoccurring in the veins, according to new research in the American Heart Association journal Circulation. In a combined analysis of two similar independent studies, 1,224 patients who received 100 mg of aspirin a day to treat blood clots were monitored for at least two years. Continue reading

Repurposing anti-depressant medication to target medulloblastoma

Repurposing anti-depressant medication to target medulloblastoma

An international research team reports in Nature Medicine a novel molecular pathway that causes an aggressive form of medulloblastoma, and suggests repurposing an anti-depressant medication to target the new pathway may help combat one of the most common brain cancers in children. Continue reading

How cellular guardians of the intestine develop

How cellular guardians of the intestine develop

Even the most careful chosen meal can contain surprises. To defend against infectious microbes, viruses or other potential hazards that find their way to the intestines, a dedicated contingent of immune cells keeps watch within the thin layer of tissue that divides the contents of the gut from the body itself Continue reading

Severing nerves may shrink stomach cancers: Botox injections slow growth of stomach tumors in mice

Severing nerves may shrink stomach cancers: Botox injections slow growth of stomach tumors in mice

Research from Columbia University Medical Center shows that nerves may play a critical role in stomach cancer growth and that blocking nerve signals using surgery or Botox® (onabotulinumtoxinA) could be an effective treatment for the disease. Continue reading

More than just X and Y: a new genetic basis for sex determination

More than just X and Y: a new genetic basis for sex determination

Men and women differ in plenty of obvious ways, and scientists have long known that genetic differences buried deep within our DNA underlie these distinctions. In the past, most research has focused on understanding how the genes that encode proteins act as sex determinants Continue reading
