(PhysOrg.com) -- By mimicking the way that a living body acquires immunity to disease through vaccination, researchers have designed an artificial immune system to solve optimization problems more effectively than before. The results show that the biologically motivated approach is better at exploring a greater amount of space and quickly locating the desired local and global optima than previous methods. http://www.physorg.com/news179060729.html Technology Thu, 03 Dec 2009 11:05:59 EST news179060729 (PhysOrg.com) -- A cancer vaccine carried into the body on a carefully engineered, fingernail-sized implant is the first to successfully eliminate tumors in mammals, scientists report this week in the journal Science Translational Medicine. http://www.physorg.com/news178382282.html Medicine & Health Wed, 25 Nov 2009 14:38:42 EST news178382282 T cells are key players in the immune response to HIV, which are able to delete infected cells. This capacity is used for vaccine development against HIV. `To date however, success of this strategy remains elusive. Our understanding of T cell efficacy is still limited, and we need to identify precise T cell correlates of protection that could guide rationale vaccine design`, says Victor Appay, Group leader HIV Pathogenesis and Immunosenescence, Hopital Pitie-Salpetriere, Paris, at the 2nd European Congress of Immunology ECI 2009 in Berlin. http://www.physorg.com/news172316676.html Medicine & Health Wed, 16 Sep 2009 11:00:01 EST news172316676 Scientists at Oregon State University have developed a new "adjuvant" that could allow the creation of important new vaccines, possibly become a universal vaccine carrier and help medical experts tackle many diseases more effectively. http://www.physorg.com/news172171724.html Medicine & Health Mon, 14 Sep 2009 18:40:02 EST news172171724 There may be a way around the harsh skin toxicity associated with a widely used cancer drug, according to a study published online this week in Cancer Biology and Therapy by researchers from City of Hope and the Kimmel Cancer at Jefferson. http://www.physorg.com/news171026841.html Medicine & Health Tue, 01 Sep 2009 12:27:57 EST news171026841 Rather than sticking to a single DNA script, human brain cells harbor astonishing genomic variability, according to scientists at the Salk Institute for Biological Studies. The findings, to be published in the Aug. 5, 2009, advance online edition of Nature, could help explain brain development and individuality, as well as lead to a better understanding of neurological disease. http://www.physorg.com/news168697506.html Medicine & Health Wed, 05 Aug 2009 13:25:34 EST news168697506 Scientists in Ohio are reporting a long-awaited advance toward making the workplace safer for more than one million machinists in the United States who may be exposed to disease-causing bacteria in contaminated metalworking fluids. Those fluids become airborne during machining of metal parts. The study appears in the current edition of ACS` monthly Journal of Proteome Research. http://www.physorg.com/news162060407.html Chemistry Wed, 20 May 2009 17:47:18 EST news162060407 For years, researchers and physicians have known that infants' immune systems do not respond well to certain vaccines, thus the need for additional boosters as children develop. Now, in a new study from the University of Missouri, one researcher has found an explanation for that poor response. In the study, the MU scientist found evidence that the immune systems of newborns might require some time after birth to mature to a point where the benefits of vaccines can be fully realized. http://www.physorg.com/news157817036.html Medicine & Health Wed, 01 Apr 2009 15:04:22 EST news157817036 Bioengineers at Harvard University have shown that small plastic disks impregnated with tumor-specific antigens and implanted under the skin can reprogram the mammalian immune system to attack tumors. http://www.physorg.com/news151866192.html Medicine & Health Thu, 22 Jan 2009 17:03:49 EST news151866192 Findings from a study conducted in mice, published in the open access journal PLoS Medicine next week, provide new insights into how an effective immune response to brain tumors could potentially be brought about in humans. http://www.physorg.com/news151053609.html Medicine & Health Tue, 13 Jan 2009 07:20:09 EST news151053609 (PhysOrg.com) -- Cutting-edge `tweezers` are so sensitive that they can feel the tell-tale tug of tiny concentrations of pathogens in blood samples, yet don`t ever need to be sterilized -or even held -as they are ephemeral and weightless. http://www.physorg.com/news145799465.html Physics Thu, 13 Nov 2008 11:51:05 EST news145799465
