The US Food and Drug Administration has approved a new insulin drug that will allow diabetics to set needles aside at mealtimes and use inhalers instead. Afrezza Inhalation Powder, however, is not a substitute for long-acting insulin. The new drug is intended to be used in combination with long-acting insulin for patients with type 1 [...]

Cellular Force That Drives Allergy And Asthma Can Be Blocked By Interferon, UT Southwestern Immunologists Find

A mechanism that could underlie the development of cells that drive asthma and allergies has been uncovered by immunology researchers at UT Southwestern Medical Center. Asthma and allergies are both driven by an inappropriate activation of the immune system, primarily a subtype of white blood cells known as T helper 2 cells, or Th2 cells. [...]

Genes Found In Nature Yield 1918-Like Virus With Pandemic Potential

An international team of researchers has shown that circulating avian influenza viruses contain all the genetic ingredients necessary to underpin the emergence of a virus similar to the deadly 1918 influenza virus. Searching public databases, the researchers, led by Yoshihiro Kawaoka of the University of Wisconsin-Madison, identified eight genes from influenza viruses isolated from wild [...]

Smokers With Gene Defect Have One In Four Chance Of Developing Lung Cancer

Around a quarter of smokers who carry a defect in the BRCA2 gene will develop lung cancer at some point in their lifetime, a large-scale, international study reveals. Scientists announce a previously unknown link between lung cancer and a particular BRCA2 defect, occurring in around 2% of the population, in research published in Nature Genetics. [...]

Results of a University of Colorado Cancer Center study presented at the 50th Annual Meeting of the American Society for Clinical Oncology (ASCO) show that a test of organic compounds in exhaled breath can not only distinguish patients with lung cancer from patients with chronic obstructive pulmonary disease (COPD), but can also define the stage [...]
