Tue, 25 Oct 2016 00:00:00 EDT(The Critical Path Institute (C-Path)) At the 2016 Union World Conference on Lung Health, C-Path's Critical Path to TB Drug Regimens initiative and WHO's Global TB Programme will co-host a symposium to update the TB researchers on the TB-ReFLECT partnership. TB-ReFLECT -- which includes research partners from the University of California, San Francisco, and the larger CPTR effort -- will perform quantitative analyses on the TB-PACTS database and use the results as tools to inform future TB trial design.
Tue, 25 Oct 2016 00:00:00 EDT(PLOS) A protein known for guarding against viral infections leads a double life, new research shows, and can interfere with cell growth and the defense against parasites. In a new paper publishing Oct. 25 in the open-access journal PLOS Biology, Johnathan Ho and Uwe Vinkemeier at the University of Nottingham, UK, and colleagues describe the duplicitous nature of this essential protein, called STAT2, which they discovered while investigating the mechanisms behind interferon signaling.
Tue, 25 Oct 2016 00:00:00 EDT(University of California - San Francisco) Researchers at UC San Francisco and the academically affiliated Gladstone Institutes have used a newly developed gene-editing system to find gene mutations that make human immune cells resistant to HIV infection.
Mon, 24 Oct 2016 00:00:00 EDT(University of California - Berkeley) UC Berkeley and Exeter University researchers propose a novel strategy to keep malarial mosquitoes out of people's homes: combine a repellent with an insecticide. The strategy uses evolution to drive mosquitoes to greater aversion to the repellent, and lowers the push by mosquitoes to develop resistance, thus extending insecticide lifetime. Efforts to find effective repellents don't need to wait for a good candidate. The strategy can turn a mediocre repellent into a good one.
Mon, 24 Oct 2016 00:00:00 EDT(Scripps Research Institute) Researchers have been trying for decades to develop a vaccine against the globally endemic hepatitis C virus. Now scientists at the Scripps Research Institute have discovered one reason why success has so far been elusive.
Mon, 24 Oct 2016 00:00:00 EDT(Washington State University) A Washington State University-led research team determined rabies vaccines stored at warmer temperatures still protect against the disease in dogs.The work, published in the journal Vaccine, could lead to improved vaccination coverage in hard to reach, rural areas in Africa and Asia where electricity for cooling is limited.
Mon, 24 Oct 2016 00:00:00 EDT(Infectious Diseases Society of America) Infectious disease experts nationwide will gather in New Orleans for the 5th annual IDWeek Oct. 26-30. A combined meeting of the Infectious Diseases Society of America (IDSA), the Society for Healthcare Epidemiology of America (SHEA), the HIV Medicine Association (HIVMA) and the Pediatric Infectious Diseases Society (PIDS), IDWeek features the latest in prevention, diagnosis, treatment, and epidemiology of infectious diseases, including HIV.
Mon, 24 Oct 2016 00:00:00 EDT(University of California - San Diego) Viruses hijack the molecular machinery in human cells to survive and replicate, often damaging those host cells in the process. Researchers at the University of California San Diego School of Medicine discovered that, for cytomegalovirus (CMV), this process relies on a human protein called CPEB1. The study provides a potential new target for the development of CMV therapies.
Mon, 24 Oct 2016 00:00:00 EDT(Imperial College London) The superbug MRSA uses decoys to evade a last-resort antibiotic, reveals new research.The findings, from scientists at Imperial College London, suggest potential new ways of tackling the bacteria, such as interfering with the decoys.
Fri, 21 Oct 2016 00:00:00 EDT(University of Liverpool) New research from the University of Liverpool highlights problems impacting on the cognitive development of children in sub-Saharan Africa.
Fri, 21 Oct 2016 00:00:00 EDT(American Academy of Pediatrics) Researchers presenting an abstract of new findings at the American Academy of Pediatrics 2016 National Conference & Exhibition tracked lice infections in more than 500 summer camps over a three-year period and found 30 percent of camps have a 'no nit policy,' which excludes campers based on the presence of lice eggs, despite evidence that no-nit policies are not effective. According to the survey, less than 20 percent of campers with nits and live lice were able to stay at camp.
Thu, 20 Oct 2016 00:00:00 EDT(Griffith University) Griffith University researchers have discovered a potential way to create an antimicrobial drug that would stop one of the world's most prevalent foodborne bugs causing gastroenteritis in humans.
Thu, 20 Oct 2016 00:00:00 EDT(Society for Disaster Medicine and Public Health) Since 2011 the Syrian Civil War has led to one of the most complex humanitarian emergencies in history. In a study conducted by pediatricians from Belgium, Egypt, Qatar and Turkey, the impact of the conflict on the familial, educational, and public health state of 1001 Syrian children was assessed.
Thu, 20 Oct 2016 00:00:00 EDT(Carnegie Mellon University) Researchers led by Carnegie Mellon University physicist Markus Deserno and University of Konstanz chemist Christine Peter have developed a computer simulation that crushes viral capsids. By allowing researchers to see how the tough shells break apart, the simulation provides a computational window for looking at how viruses and proteins assemble.
Thu, 20 Oct 2016 00:00:00 EDT(Emory Health Sciences) A recent study published in the Journal of Virology, by joint efforts among scientists from Emory, India and Thailand, sheds novel insights on the properties of a class of immune cells known as CD8 T cells, which are involved in fighting dengue virus infection.
Thu, 20 Oct 2016 00:00:00 EDT(PLOS) People with Icelandic heritage are more likely to carry a novel rare mutation in the TM2D3 gene, which leads to greater risk for Alzheimer's disease, based on a new study published Oct. 14, 2016, in PLOS Genetics by Johanna Jakobsdottir of the Icelandic Heart Association, Sven van der Lee of Erasmus University in Rotterdam, and colleagues.
Thu, 20 Oct 2016 00:00:00 EDT(University of California - San Francisco) UCSF researchers have found in autopsy tissue samples of patients treated with antiretrovirals that the virus evolved and migrated among tissues similar to the way it did in patients who had never received antiretroviral treatment, despite the fact that the treated patients had undetectable levels of virus in their blood.
Thu, 20 Oct 2016 00:00:00 EDT(University of California - San Diego) Researchers at University of California San Diego School of Medicine have discovered that Zika virus infection leads to modifications of both viral and human genetic material. These modifications -- chemical tags known as methyl groups -- influence viral replication and the human immune response.
Thu, 20 Oct 2016 00:00:00 EDT(Fred Hutchinson Cancer Research Center) A table-top device that enables medical staff to genetically manipulate a patient's blood to deliver potential new therapies for cancer, HIV and other diseases would eliminate the need for multi-million-dollar 'clean rooms,' making gene therapy more possible for even the poorest of countries.
Thu, 20 Oct 2016 00:00:00 EDT(University of Montreal) A Canada-US study published in Cell has demonstrated that Americans of African descent have a stronger immune response to infection compared to Americans of European descent. Neanderthals also played a role in the immune response to infection. The analysis of research team shows that about 3 percent of the genes involved in the differences in immune responses between African and European Americans come from Neanderthals!
Thu, 20 Oct 2016 00:00:00 EDT(Duke University) Large swaths of DNA and RNA are dotted with chemical tags, acting like Post-It notes, that provide additional instructions to the underlying genetic code. The most abundant of these modifications is called N6-methyladenosine. Duke and Weill Cornell researchers have shown that RNA viruses are littered with N6-methyladenosine tags, which affect the ability of these viruses to infect cells and, ultimately, their human hosts. The findings could lead to new strategies for combating viral pathogens.
