UL GEMS students host third annual Teddy Bear Hospital event for primary school children

Medical School students at the University of Limerick today hosted the University’s annual Teddy Bear Hospital (TBH) with over 400 Limerick’s primary school children from 6 different schools and their teddy bears. The aim of the event, which has been organised by six current Graduate Entry Medical School (GEMS) students with a particular interest in childhood medicine, is to alleviate childhood anxiety about the medical environment, its procedures and the professionals that work within it.

New research identifies promising drug therapy target for breast cancer

The genome of a cell is under constant attack, suffering DNA damage that requires an army of repair mechanisms to keep the cell healthy and alive. Understanding the behavior of the enzymes defending these assaults helps determine how - and where - cancer gets its foothold and flourishes.

CT coronary angiography can accurately diagnose coronary artery disease

Use of computed tomography coronary angiography, which provides 3-D images of the heart, coupled with standard care allows doctors to more accurately diagnose coronary artery disease in patients presenting with chest pain, therefore, leading to more appropriate follow-up testing and treatments, according to research presented at the American College of Cardiology's 64th Annual Scientific Session.

Scientists use x-ray vision to probe early stages of DNA 'photocopying'

Scientists at Johns Hopkins have created a 3-D model of a complex protein machine, ORC, which helps prepare DNA to be duplicated.

Super-resolution microscopes reveal the link between genome packaging and cell pluripotency

In 1953 Watson and Crick first published the discovery of the double helix structure of the DNA. They were able to visualize the DNA structure by means of X-Ray diffraction. Techniques, such as electron microscopy, allowed scientists to identify nucleosomes, the first and most basic level of chromosome organisation

Vrije University Brussels installs MILabs PET-SPECT-CT-MRI platform for nanobody research

The comprehensive MILabs PET-SPECT-CT-MR preclinical platform combines the best PET-SPECT functional imaging capabilities (sub-half-mm SPECT resolution and sub-mm PET resolution) with high resolution anatomical imaging from an integrated X-ray CT subsystem and/or a compact cryogen free 1.5 T MRI unit

Researchers developing new mercury-free material to treat tooth decay

Tooth decay is a serious health problem and it is often necessary to repair cavities. Today they often use a composite filling material made of acrylate compounds, as it resembles the colour of the teeth and is reasonably strong so it can handle the rigors of the powerful chewing movements.

New X-ray diagnostic imaging designed to meet the needs of hospitals in developing countries

In developing countries, many hospitals have become cemeteries of medical equipment. Several radiology systems, often sent by international aid, may never be used due to the climatic conditions and the instability of electricity networks. In a matter of weeks, they become useless. Besides, the lack of qualified personnel or spare parts rapidly dispels any hope to make them work. Yet, the lack of access to radiology in many developing countries is a serious public health problem, whether for TB screening or the care of road traffic injuries.

Understanding strengths and weaknesses of hepatitis C viruses

Using a specially selected library of different hepatitis C viruses, a team of researchers led by Johns Hopkins scientists has identified tiny differences in the pathogens' outer shell proteins that underpin their resistance to antibodies.

Weak spots in ebola’s defenses: an interview with Dr. Andrew Ward

There are hundreds of other antibodies against Ebola that we are in the process of imaging using the electron microscope. We are looking for new sites of vulnerability as well as subtle differences in the way the known sites are attacked. In particular we are looking for antibodies that the virus is unlikely to escape from when it mutates.

Nanobody Nano-85 holds promise for detection of noroviral RNA

Infection with highly contagious noroviruses, while not usually fatal, can lead to a slew of unpleasant symptoms such as excessive vomiting and diarrhea. Current treatment options are limited to rehydration of the patient. "Additionally, noroviruses come in a variety of constantly evolving strains.

Neuroprotective compounds can limit damage to the brain during ischemic stroke

In the 1990s, neuroscientists identified a class of drugs that showed promise in the area of stroke. NMDA receptor antagonists could limit damage to the brain in animal models of stroke. But one problem complicated testing the drugs in a clinical setting: the side effects included disorientation and hallucinations.
