Suneva Medical, a privately-held aesthetic medical device company, announced that Christopher B. Zachary, MBBS, FRCP, Professor and Chair, Department of Dermatology, University of California, Irvine, presented 18-month interim results from the prospective, open-label, five-year safety and patient satisfaction study on Artefill for nasolabial fold (NLF) correction. The data were presented at the Skin Disease Education Foundation's 34th Annual "Hawaii Dermatology Seminar" in Waikoloa, Hawaii February 14-19th. Dr. Zachary commented, "The safety data presented at the Hawaii Dermatology Seminar should give aesthetic physicians some long awaited encouragement to view Artefill on its merits as a safe and long-lasting dermal filler.
A new 'fertility chip', developed by researchers at the University of Twente's MESA+ Institute for Nanotechnology, can accurately count spermatozoa in sperm. This is an important step towards the development of a compact device for reliable 'pre-scanning' of male fertility. The researchers are publishing the invention of the chip in the scientific journal Lab on a Chip. Every year more than 10, 000 couples in the Netherlands apply for help because of involuntary childlessness. A sperm analysis is typically the first step of fertility research. Testing sperm quality requires stringent pre-test preparations and a specialized laboratory. Tests often have to be repeated two to five times for sufficient reliability.
Building on his Nobel Prize-winning work creating fluorescent proteins that light up the inner workings of cells, a team of researchers led by Howard Hughes Medical Institute investigator Roger Tsien, PhD, professor of pharmacology, chemistry and biochemistry at the University of California, San Diego and the Moores UCSD Cancer Center has developed biological probes that can stick to and light up tumors in mice. The scientists were able to spot and remove more cancerous tissue in mice injected with the fluorescent probes than in those mice without the fluorescent probes, upping survival five-fold. The findings - reported online the week of February 15 in the early edition of the Proceedings of the National Academy of Sciences - are the latest steps in research aimed at helping surgeons see the outlines of cancerous tumors in real time, and promise to open new doors to using molecular tools in the operating room.
An inexpensive, fast, accurate DNA test that reveals a person's risk of developing certain diseases is expected to become a reality, thanks to technology developed at the University of Edinburgh. Scientists have developed a method of pinpointing variations in a person's genetic code at critical points along the DNA chain. The technique could be used to analyse DNA in a drop of saliva. Tiny differences or omissions in DNA code can determine whether or not a person is healthy, susceptible to disease, or has a serious or life-threatening condition, such as cystic fibrosis. The technology seeks to enable improved personal diagnosis, allowing prompt, appropriate treatment for patients.
United States Attorney Karen P. Hewitt announced that James Folsom was sentenced in federal court in San Diego to serve 51 months in custody and a $250, 000 fine following his conviction on twenty-six felony counts relating to the sale of unapproved medical devices and the commission of offenses while on pretrial release. The Honorable John A. Houston, United States District Judge, also ordered the destruction of over 450 devices that had been seized by the government during the execution of a search warrant at a self-storage unit used by the defendant. A federal jury found Folsom guilty of conspiring to ship adulterated and misbranded Rife-type biofrequency devices in interstate commerce, following a two-week trial in 2009.
Scientists funded by the Biotechnology and Biological Sciences Research Council and the British Heart Foundation at the University of Oxford have developed a revolutionary way of capturing a high-resolution still image alongside very high-speed video - a new technology that is attractive for science, industry and consumer sectors alike. By combining off-the-shelf technologies found in standard cameras and digital movie projectors they have successfully created a tool that will transform many forms of detailed scientific imaging and could provide access to high-speed video with high-resolution still images from the same camera at a price suitable for the consumer market.
