Fri, 21 Jul 2017 00:00:00 EDT

(Liverpool School of Tropical Medicine) Researchers at LSTM have been awarded £6.4 million from the Global Challenges Research Fund to strengthen the global capacity to control vector-borne diseases. Professor Hilary Ranson, Head of LSTM's Department of Vector Biology, will lead a team of experts working with leading research institutes and national disease control programs in three African countries with exceptionally high burdens of disease, to develop evidence based solutions for integrated vector control.

Francis Crick Institute to train top African scientists

Thu, 20 Jul 2017 00:00:00 EDT

(The Francis Crick Institute) The Francis Crick Institute and five partner institutes in Africa have today announced a fellowship program to train African researchers to tackle infectious diseases in their home countries. The program, called the Crick African Network, is supported by a £6 million grant from the Global Challenges Research Fund, a five-year initiative led by the UK Department for Business, Energy and Industrial Strategy to address problems faced by developing countries.

Innate reaction of hematopoietic stem cells to severe infections

Thu, 20 Jul 2017 00:00:00 EDT

(University of Zurich) Researchers at the University of Zurich have shown for the first time that hematopoietic stem cells detect infectious agents themselves and begin to divide -- that is, without signals from growth factors. This direct production of defensive cells damages hematopoiesis in the long term, however, which could lead to malignant hematopoietic stem cell diseases at advanced age.

Report links USGov global health funding to thousands of US jobs, millions lives saved

Thu, 20 Jul 2017 00:00:00 EDT

(Burness) President Trump's proposal to slash public investments in the fight against global threats such as malaria, Ebola and AIDS would imperil programs that generate thousands of jobs in the United States, as they deliver breakthrough innovations that are saving millions of lives around the world, according to a new report issued today from the Global Health Technologies Coalition.

Skin vaccination with microneedle patch, influenza fusion protein improves efficacy of flu vaccines

Wed, 19 Jul 2017 00:00:00 EDT

(Georgia State University) A boosting skin vaccination with a biodegradable microneedle patch and protein constructed from sequences of influenza virus subtypes could improve the effectiveness of conventional influenza vaccines, according to a study led by Georgia State University.

Certification program to expand response capability for vector-borne disease outbreaks

Wed, 19 Jul 2017 00:00:00 EDT

(Entomological Society of America) Soon, the public health community will be better equipped to respond to outbreaks of diseases spread by mosquitoes and other arthropod vectors, thanks to a contract awarded to the Entomological Society of America Certification Corporation by the Centers for Disease Control and Prevention. Over the course of the next year, the ESA Certification Corporation will train and certify approximately 30 entomologists to participate as entomological specialists on CDC Emergency Response Teams.

Kent State researcher examines vaccine rejection and hesitancy, calls to promote vaccination

Wed, 19 Jul 2017 00:00:00 EDT

(Kent State University) The center of a public health debate is whether parents should have their children vaccinated. Tara Smith, Ph.D., professor of epidemiology at Kent State University's College of Public Health, challenges statements made by influential individuals who oppose the widespread use of vaccines, and she calls upon her colleagues in the scientific community to speak out to promote vaccination.

Saliva as good as blood for diagnosing hepatitis E, study suggests

Wed, 19 Jul 2017 00:00:00 EDT

(Johns Hopkins University Bloomberg School of Public Health) A saliva test developed by researchers at the Johns Hopkins Bloomberg School of Public Health nearly matches the performance of a blood test widely used to assess recent or past hepatitis E virus (HEV) infection, a new study reports.

New animal models for hepatitis C could pave the way for a vaccine

Wed, 19 Jul 2017 00:00:00 EDT

(Rockefeller University) In the rats that roam New York City's streets and tunnels, scientists have found a virus that resembles hepatitis C. They have used it to create the first animal model of the human disease, a breakthrough that potentially could yield a much-needed vaccine.

Titanium dioxide nanoparticles can exacerbate colitis

Wed, 19 Jul 2017 00:00:00 EDT

(University of Zurich) Titanium dioxide, one of the most-produced nanoparticles worldwide, is being used increasingly in foodstuffs. When intestinal cells absorb titanium dioxide particles, this leads to increased inflammation and damage to the intestinal mucosa in mice with colitis. Researchers at the University of Zurich recommend that patients with colitis should avoid food containing titanium dioxide particles.

New way found to boost immunity in fight cancer and infections

Wed, 19 Jul 2017 00:00:00 EDT

(University of Montreal) Medical professor Christopher Rudd and his research team have identified a key new mechanism that regulates the ability of T-cells of the immune system to react against foreign antigens and cancer.

Massive simulation shows HIV capsid interacting with its environment

Wed, 19 Jul 2017 00:00:00 EDT

(University of Illinois at Urbana-Champaign) It took two years on a supercomputer to simulate 1.2 microseconds in the life of the HIV capsid, a protein cage that shuttles the HIV virus to the nucleus of a human cell. The 64-million-atom simulation offers new insights into how the virus senses its environment and completes its infective cycle.

Tue, 18 Jul 2017 00:00:00 EDT

(University of California - Berkeley) A new test is the best-to-date in differentiating Zika virus infections from infections caused by similar viruses. The assay is currently in the licensing process and researchers hope it will be available to the medical community soon.

Failures in stethoscope hygiene can lead to patient infections

Tue, 18 Jul 2017 00:00:00 EDT

(Elsevier) You can lead a doctor to disinfection, but how do you get them to clean ... or wipe ... or swab a stethoscope?That's the question raised by a new quality improvement project published in the July issue of the American Journal of Infection Control, the official journal of the Association for Professionals in Infection Control and Epidemiology. It is the latest report to find that healthcare providers rarely perform stethoscope hygiene between patient encounters, despite its importance for infection prevention.

'Superbugs' study reveals complex picture of E. coli bloodstream infections

Tue, 18 Jul 2017 00:00:00 EDT

(Wellcome Trust Sanger Institute) The first large-scale genetic study of Escherichia coli (E. coli) cultured from patients with bloodstream infections in England showed that drug resistant 'superbugs' don't always out-compete other strains. Research by the Wellcome Trust Sanger Institute and their collaborators showed that new types of E. coli occur frequently, but unlike in some other infections, drug-resistant strains do not become a dominant cause of infection.

Material from shellfish delivers a boost to bioassays and medical tests

Mon, 17 Jul 2017 00:00:00 EDT

(University of Washington) Scientists at the University of Washington have discovered a simple way to raise the accuracy of diagnostic tests for medicine and common assays for laboratory research. By adding polydopamine -- a material that was first isolated from shellfish -- to these tests at a key step, the team could increase the sensitivity of these common bioassays by as many as 100 to 1,000 times.

Newly identified genetic marker may help detect high-risk flu patients

Mon, 17 Jul 2017 00:00:00 EDT
