Key Mechanism Found That Promotes Spread Of Malignant Melanoma
Researchers at Northwestern University have discovered a key signaling mechanism that may promote the ability of highly aggressive malignant melanoma cells to metastasize, or spread from a primary tumor to distant sites within the body.Results of their study, published in the November issue of Cancer Research, suggest that the signaling mechanism may be a potential target for prevention of metastatic melanoma. First Evidence That Female Human Embryos Adjust The Balance Of X
Researchers have found the first evidence that a process of inactivating the X chromosome during embryo development and implantation, which was known to occur in mice but unknown in humans, does, in fact, take place in human female embryos prior to implantation in the womb. In Early Embryos, Cilia Get The Message Across
How a perfectly symmetrical embryo settles on what's right and what's left has fascinated developmental biologists for a long time. The turning point came when the rotational beating of cilia, hair-like structures found on most cells, was identified as essential to the process. Now, scientists at the Salk Institute for Biological Studies take a step back and illuminate the molecular process that regulates formation of cilia in early fish embryos. Prostate Cancer Therapy - Study Suggests New Molecular Screening Theor
Levels of the Smad7 protein may predict therapeutic response in patients with prostate cancer according to research published today by investigators at the Uppsala Branch of the Ludwig Institute for Cancer Research (LICR). Space Shuttle Experiment Shows Live Cells Influence Growth Of Nanostru
Sensors, TB modeling, cell preparation, and surgical implant safety may all be improved by a Sandia Labs and University of New Mexico discovery that live cells improve nanostructures when inserted in slurry that, drying, self-assembles into them.The nanostructures support single-cell life forms that are sensitive to and interact with their environment. [Ironic] An Italian pensioner committed suicide after his wife fell in
Recalling the end of Romeo and Juliet, the 70-year-old man, Ettore, who had sat by his wife's bedside for four months after she slipped into a coma following a heart attack, finally gave up hope and gassed himself in the garage of his family home.Less than a day later, his wife, Rossana, woke up in her hospital bed in Padua and immediately asked for him. Coin &Conscience: Popular Views of Money, Credit and Speculation
This exhibit features historical images (from the 16th through the 19th centuries) depicting themes related to money and finance, such as bankers, stock exchanges, the "money devil,"credit and speculation, "misers, moneylenders, and thieves,"love and money, and "vanity and virtue: allegories on the pursuit of riches."View images by theme or artist. Includes an introduction to the collection and a selected bibliography. From the Bleichroeder Collection at the Baker Library, Harvard Business School. Fast Way Of Spotting Multidrug Resistant Bacteria Could Help Stop Outb
A type of bacterium widely found on our skin and in the environment has now become a major threat in hospitals where it can cause serious infections, such as pneumonia in severely ill patients. Like the well known bacterium MRSA (methicillin resistant Staphylococcus aureus) the new types of Acinetobacter baumannii are resistant to nearly all antibiotics, so doctors have very few treatments available, and three resistant strains are currently circulating in the UK. Discarded Placentas Deliver Researchers Promising Cells Similar To Emb
Routinely discarded as medical waste, placentas could feasibly provide an abundant source of cells with the same potential to treat diseases and regenerate tissues as their more controversial counterparts, embryonic stem cells, suggests a University of Pittsburgh study to be published in the journal Stem Cellsand available now as an early online publication in Stem Cells Express. New Mathematical Model Unravels The Mechanics Of Microbe Reproduction
In process that is shrouded in mystery, rod-shaped bacteria reproduce by splitting themselves in two. By applying advanced mathematics to laboratory data, scientists have solved a small but important part of this reproductive puzzle.
