WASHINGTON, May 20 /PRNewswire/ -- - New study shows inhaling long, thin carbon nanotubes may result in asbestos-related disease A major study published today in Nature Nanotechnology suggests some forms of carbon nanotubes -- a poster child for the "nanotechnology revolution" -- could be as harmful as asbestos if inhaled in sufficient quantities. The study used established methods to see if specific types of nanotubes have the potential to cause mesothelioma -- a cancer of the lung lining that can take 30-40 years to appear following exposure. The results show that long, thin multi-walled…

Discovered nearly 20 years ago, carbon nanotubes have been described as the wonder material of the 21st Century. Light as plastic and stronger that steel, they are being developed for use in new drugs, energy-efficient batteries and futuristic electronics. A major study published today suggests some forms of carbon nanotubes, the poster children for the “nanotechnology revolution”, could be as harmful as asbestos if inhaled in sufficient quantities. The study used established methods to see if specific types of nanotubes have the potential to cause mesothelioma — a cancer of the lung lining…

Researchers at the Peninsula Medical School in the South West of England, University College London, the San Raffaele Scientific Institute in Milan and Cancer Research UK, have for the first time identified a protein that is key to the regeneration of damage in the peripheral nervous system and which could with further research lead to understanding diseases of our peripheral nervous systems and provide clues to methods of repairing damage in the central nervous system, according to a paper published this week in the Journal of Cell Biology. The team looked at a protein called c-Jun, a…

HILDEN, Germany, May 20 /PRNewswire/ -- - Research Supports Replacement of Pap with HPV Test as Front-line Screen Long-term data from a study published in the International Journal of Cancer show that women screened only with a human papillomavirus (HPV) DNA test are half as likely to develop moderate to severe cervical disease over the next six years as those who get only conventional cytology (the Pap "smear"). The research followed nearly 3,000 women age 35 years and older, and assessed their HPV status using QIAGEN's digene(R) HPV Test - the only such test that is both CE-marked in…

Researchers from the University of Melbourne, Australia, and the University of Texas, USA, have extracted genes from the extinct Tasmanian tiger (thylacine), inserted it into a mouse and observed a biological function – this is a world first for the use of the DNA of an extinct species to induce a functional response in another living organism. The results, published in the international scientific journal PLoS ONE this week, showed that the thylacine Col2a1 gene has a similar function in developing cartilage and bone development as the Col2a1 gene does in the mouse. “This is the first time…

SAN DIEGO, May 19 /PRNewswire/ -- - Superiority of Ablation Therapy Using HALO System Demonstrated for Eradicating Barrett's Esophagus and Reducing Risk for Disease Progression Booth #2349 -- Digestive Disease Week -- BARRX Medical, Inc., a technology leader in the design and manufacture of medical devices for digestive diseases, today announced the presentation of a landmark study entitled, "A Randomized, Multicenter, Sham-Controlled Trial of Radiofrequency Ablation (RFA) for Subjects with Barrett's Esophagus (BE) Containing Dysplasia: Interim Results of the AIM Dysplasia Trial." The study…

DUBLIN, May 19 /PRNewswire/ -- A young lady from New Zealand who discovered that chewing sugar-free gum made her seriously ill has bravely agreed to act as a guinea-pig in an experiment in California. Abby Cormack, 26, hopes that the potentially dangerous tests, to take place next month, will show that the ingestion of aspartame causes an aberration of blood capillary and neuron function. Multimedia News Release: http://www.prnewswire.com/mnr/zsweet/32699/ This is the first time any human has voluntarily subjected themselves to such damaging experimentation to prove the correlation between…

Pancreatic cancer, the fourth-leading cause of cancer death in this country, takes some 34,000 lives a year. It's usually detected after it has already spread and only 4 percent of individuals with pancreatic cancer live for five years after diagnosis. An herb used in traditional medicine by Middle Eastern countries may help in the fight against pancreatic cancer, say researchers at Thomas Jefferson University in Philadelphia. They have found that thymoquinone, an extract of nigella sativa seed oil, blocked pancreatic cancer cell growth and killed the cells by enhancing the process of…

With systems biology methods, CancerSys investigates molecular- and cell-biological processes in the formation of tumors in the liver Systems Biology is a young field with the overall aim of creating a holistic picture of dynamic life processes with regard to all levels - from the genome via the proteome and the organisation of the cell organelles all the way to the complete cell or even an entire organism. In doing so, Systems Biology takes into consideration the dynamic interplay of the components involved. In order to achieve this high aspiration, Systems Biology combines quantitative…
