Otitis Media

Ultrasound aids ear infection diagnosis

Although traditionally an imaging modality, ultrasound also has applications as a measurement tool. An innovative application is to assess ear infections. Otitis Media (OM), a middle ear infection, is the number one indication for antibiotic prescriptions for children and the leading cause for surgery. This problem is global. Nearly every child will suffer at least one middle ear infection severe…

No chance for bacteria on implants

Hip and dental implant operations are routine. But not entirely risk-free. They may result in infection that is difficult to control with oral or intravenous antibiotics. In such cases, the implant will probably need to be replaced. Fraunhofer researchers can now apply a precisely matched drug directly to the replacement implant while significantly increasing the effectiveness of the antibiotic…

Laser-activated silk sealants outperform sutures for tissue repair

Researchers have developed laser-activated nanomaterials that integrate with wounded tissues to form seals that are superior to sutures for containing body fluids and preventing bacterial infection. Tissue repair following injury or during surgery is conventionally performed with sutures and staples, which can cause tissue damage and complications, including infection. Glues and adhesives have…

New techniques detects Lyme disease weeks before current tests

Researchers have developed techniques to detect Lyme disease bacteria weeks sooner than current tests, allowing patients to start treatment earlier. The new techniques can detect an active infection with the Lyme bacteria faster than the three weeks it takes for the current indirect antibody-based tests, which have been a standard since 1994. Another advantage of the new tests is that a positive…

Zika virus strips immune cells of their identity

Macrophages are immune cells that are supposed to protect the body from infection by viruses and bacteria. Yet Zika virus preferentially infects these cells. Researchers at University of California San Diego School of Medicine have now unraveled how the virus shuts down the genes that make macrophages function as immune cells.

Could these special antibodies lead to HIV vaccine?

Around one percent of people infected with HIV produce antibodies that block most strains of the virus. These broadly acting antibodies provide the key to developing an effective vaccine against HIV. Researchers from the University of Zurich and the University Hospital Zurich have now shown that the genome of the HI virus is a decisive factor in determining which antibodies are formed.

World Sepsis Day 2018

Beckman Coulter sponsored 2nd World Sepsis Congress

Beckman Coulter was a gold sponsor of the 2nd World Sepsis Congress, a free-of-charge online conference, hosted by the Global Sepsis Alliance, that took place on Sept. 5 and 6, 2018. Over the course of 17 sessions, more than 100 speakers from approximately 30 countries discussed the wide-ranging implications of sepsis and how to raise public awareness of this often-fatal condition.

Zika virus proteins inhibit brain development

In healthy individuals, the Zika virus causes flu-like symptoms. If a pregnant woman becomes infected, the unborn child can suffer from severe brain abnormalities as a result of mechanisms that have not yet been explained. A study by the Technical University of Munich (TUM) and the Max Planck Institute of Biochemistry (MPI-B) shows that Zika virus proteins bind to cellular proteins that are…

Pathway Ebola virus uses to enter cells pinpointed

The new outbreak of the deadly Ebola virus declared just last week in eastern Democratic Republic of Congo is believed to have claimed more than 30 victims so far, highlighting the continued urgency to find a way to stop the pathogen from killing the people it infects. A new study is shedding light on the role of specific proteins that trigger a mechanism allowing Ebola virus to enter cells to…

Potential diagnostic test for Kawasaki disease

For the first time, researchers at University of California San Diego School of Medicine and Imperial College London, with international collaborators, have determined that Kawasaki disease (KD) can be accurately diagnosed on the basis of the pattern of host gene expression in whole blood. The finding could lead to a diagnostic blood test to distinguish KD from other infectious and inflammatory…
