Herpes zoster, also known as shingles, is very rare among children who have been vaccinated against chicken pox, according to a Kaiser Permanente study in the December issue of the Pediatric Infectious Diseases Journal. http://www.physorg.com/news179133924.html Medicine & Health Fri, 04 Dec 2009 07:50:01 EST news179133924 Tiny strands of RNA previously dismissed as cellular junk are actually very stable molecules that may play significant roles in cellular processes, according to researchers at the University of Pittsburgh School of Medicine and the University of Pittsburgh Cancer Institute (UPCI). http://www.physorg.com/news174661464.html Biology Tue, 13 Oct 2009 14:05:41 EST news174661464 Tokyo University Hospital will begin a clinical test in late August of a viral therapy in which viruses are injected directly into brain tumor patients, according to hospital officials. http://www.physorg.com/news169653035.html Medicine & Health Sun, 16 Aug 2009 15:00:02 EST news169653035 UCSF researchers have identified a new potential drug target for the herpes virus that causes Kaposi's sarcoma, re-opening the possibility of using the class of drugs called protease inhibitors against the full herpes family of viruses, which for 20 years has been deemed too difficult to attain. http://www.physorg.com/news168173241.html Chemistry Thu, 30 Jul 2009 11:50:52 EST news168173241 Researchers at the Moores UCSD Cancer Center are injecting a modified herpes virus into melanoma tumors, hoping to kill the cancer cells while also bolstering the body's immune defenses against the disease. http://www.physorg.com/news165687558.html Medicine & Health Wed, 01 Jul 2009 17:20:27 EST news165687558 Scientists know that some cancers are triggered by viruses, which take over cellular systems and cause uncontrolled cell growth. Doctors - and patients who get shingles late in life - have also known for many years that some viruses, particularly the herpes virus, can lie dormant in a person's cells for long periods of time and then reactivate, causing disease. These viruses also cause significant disease in immunosuppressed people and those living with HIV/AIDS. http://www.physorg.com/news165515047.html Medicine & Health Mon, 29 Jun 2009 18:10:02 EST news165515047 Viruses are molecular marauders, plundering cells for the resources they need to multiply. Of central importance for viruses is the ability to commandeer cellular gene expression machinery. Several human herpesviruses put the breaks on normal cellular gene expression to divert the associated enzymes and resources towards their own viral genes. Kaposi's sarcoma-associated herpesvirus (KSHV), which causes several AIDS-associated cancers, has now been shown to do this in an unexpected way, using a process that is normally protective, called polyadenylation. http://www.physorg.com/news162625056.html Biology Wed, 27 May 2009 06:38:19 EST news162625056 (PhysOrg.com) -- A new study suggests for the first time that cytomegalovirus (CMV), a common viral infection affecting between 60 and 99 percent of adults worldwide, is a cause of high blood pressure, a leading risk factor for heart disease, stroke and kidney disease. http://www.physorg.com/news161604050.html Medicine & Health Fri, 15 May 2009 11:01:32 EST news161604050 A recently completed international multi-center clinical trial has found that acyclovir, a drug widely used as a safe and effective treatment to suppress herpes simplex virus-2 (HSV-2), which is the most common cause of genital herpes, does not reduce the risk of HIV transmission when taken by people infected with both HIV and HSV-2. http://www.physorg.com/news160995218.html Medicine & Health Fri, 08 May 2009 09:54:05 EST news160995218 (PhysOrg.com) -- Researchers have discovered the atomic structure of a powerful "molecular motor" that packages DNA into the head segment of some viruses during their assembly, an essential step in their ability to multiply and infect new host organisms. http://www.physorg.com/news149344139.html Biology Wed, 24 Dec 2008 12:28:59 EST news149344139 Rugby players may get more than just the ball out of a scrum - herpes virus can cause a skin disease called "scrumpox" and it spreads through physical contact. Researchers have studied the spread of the disease among sumo wrestlers in Japan and have discovered that a new strain of the virus could be even more pathogenic, according to an article published in the October issue of the Journal of General Virology. http://www.physorg.com/news141877666.html Biology Mon, 29 Sep 2008 03:27:46 EST news141877666
