Hormone melatonin improves egg quality in IVF

Poor egg (oocyte) quality is an important cause of female infertility. Low quality eggs may have several problems, for example they may not divide properly, or they may be missing certain chromosomes. Egg quality also declines with age, and certain medical conditions, such as PolyCystic Ovary Syndrome, can lead to poor quality eggs.

Discovery of Hsp90 protein's pattern of motion paves way for new drug target in cancer therapy

The protein Hsp90 plays a significant role in the survival of cells that are exposed to stress. Researchers at the Technische Universitaet Muenchen (TUM) uncovered this protein's mode of operation some time ago - but now Hsp90 has surprised even the experts with an unexpected pattern of motion. The results are published in the current online issue of the renowned science journal PNAS and may help researchers discover specific cancer medication.

Research on OGF-OGFr complex helps to understand pathobiology of diseases

Researchers at The Pennsylvania State University College of Medicine, Hershey, Pennsylvania have discovered that the Opioid Growth Factor (OGF, [Met5]-enkephalin) and its receptor, OGFr, a clinically important system with potent antitumor properties, has controlled entry from the cytoplasm to the nucleus. The nucleocytoplasmic passage of OGF-OGFr is critical to cell proliferation and suggests that there are hierarchical levels of nuclear import.

Researchers develop tiny color-changing sensor molecules

A new approach to building an "artificial nose" using fluorescent compounds and DNA could accelerate the use of sniffing sensors into the realm of mass production and widespread use, say Stanford chemists. If their method lives up to its promise, it could one day detect everything from incipiently souring milk to high explosives.
