Chemists at Harvard University have developed the first technique providing a real-time, molecule-by-molecule "movie" of protein production in live cells.
Unprecedented single molecule imaging movies of living cell membranes, taken by a research team based at Kyoto University and the University of New Mexico, have clarified a decades-old enigma surrounding receptor molecule behaviors. The results, appearing in the latest issue of the Journal of Cell Biology, promise to open the door to new possibilities for drug development.
Scientists at the University of Cincinnati (UC) College of Medicine have discovered the cause of a deadly type of secondary stroke known as cerebral vasospasm.
Researchers in the laboratory of Dr. Jayakrishna Ambati at the University of Kentucky have discovered the first naturally occurring molecule that selectively blocks lymphatic vessel growth. In an article in the Aug. 9, 2009 online edition of Nature Medicine, they report the identification of a new molecule known as soluble VEGFR-2 that blocks lymphangiogenesis - the growth of lymphatics - but not blood vessel growth.
French medical researchers from the AP-HP (Henri Mondor Hospital and Avicenne Hospital) and Inserm (Unit 738 "Models and methods for therapeutic evaluation of chronic illnesses" and CIC 202, at Tours) have recently demonstrated the effectiveness of a new molecule in the fight against lice. Faced with the emergence of increasing resistance to conventional treatments by these parasites, this new medication represents a real therapeutic alternative which is effective in 95% of cases.
Hopkins researchers have discovered a single molecule that is a cause of an autoimmune disease in the central nervous system, called transverse myelitis (TM), that is related to multiple sclerosis.
Researchers at Cold Spring Harbor Laboratory have discovered a new kind of messenger RNA molecule that is converted from non-protein coding status to protein coding status in response to cellular stress such as viral infection.
The scientists replaced a single atom from the molecular structure of vancomycin aglycon, a glycopeptide antibiotic that attacks the bacteria by inhibiting cell wall synthesis, significantly increasing the drug's spectrum of activity.
