Is it allergies?

How is COVID-19 making this year more challenging for allergy sufferers?

Dr. Anne Ellis: Reduced access to primary care will be an issue for patients who suffer from seasonal allergies. Fortunately, most if not all allergy practices have converted to telemedicine and/or virtual care so people can still get in touch with their treating allergist at this time, and pharmacies remain open.

How are seasonal allergy symptoms similar and different to COVID-19?

Innate Immune Memory in Asthma and the Quest for Targeted Immunotherapies

Dr. Eva Kaufmann’s research explores a new concept in innate immunity, termed "innate immune memory", or "trained immunity". Her lab studies whether allergen exposure induces long-lasting epigenetic changes in hematopoietic stem cells and innate immune cells, such as monocytes. Such epigenetic reprogramming can be a reason why asthmatic individuals experience exacerbations and are more susceptible to severe clinical trajectories of respiratory infections.

The Tiniest Tree of Life

COVID-19, the second pandemic of the current century, is still an ongoing global health emergency. Its complications and mortality are associated with pneumonia and alterations in the pulmonary vasculature. Acquiring 3D images of vascular trees in animal models provide a useful tool to evaluate the effects of COVID-19 in humans. In our research aimed at finding new drugs for COVID-19 under the supervision of Dr. Stephen Archer, vascular trees of a mouse were pressure perfused to maximal dilation with a radio-opaque material (barium). The heart and lungs were fixed and scanned using VECTor4CT scanner. VECTor4CT is the first tri-modality imaging system equipped with an ultra-high-resolution micro-computed tomography (µCT) scanner at Queen’s University.

Is DNA key to whether you get COVID-19?

kvd1 — Wed, 12 Aug 2020 17:27:27 +0000

The strength and health of one’s immune system is one key indicator of susceptibility to contracting pathogens, including the novel coronavirus. However, new evidence that may suggest more men get coronavirus than women has motivated an international hunt for which genes make people especially vulnerable or resistant to COVID-19.

Conversations Confronting COVID-19: Aging

kvd1 — Wed, 29 Jul 2020 14:33:56 +0000

The COVID-19 pandemic has threatened our health and communities, including some of our most vulnerable populations, such as the elderly. Have we failed or succeeded in our duty to safeguard the most vulnerable members of our society? What has the national and global response to the pandemic taught us about our preparedness for such a virus? How will the pandemic influence our long-term strategy for healthy aging? These are some of the important questions we examined during Conversations Confronting COVID-19: Aging, the second session in the virtual event series.

Critical funding for health research

Seven Queen’s University researchers are contributing their knowledge in the areas of melanoma, intensive care unit survivors, postoperative pain, diabetes medication, Indigenous public health, and depression thanks to funding from the Canadian Institutes of Health Research.

Queen’s received a total of $3.95 million from the Fall 2019 CIHR Project Grant competition, a program that helps advance health-related research. With an eye on collaboration, the competition funds both individuals and groups of researchers at any career stage in all areas of health-related research.

Super-resolution confocal microscopy of rat pulmonary artery smooth muscle cells showing a network of mitochondria (green) and the location of mitochondrial Complex I (red). We are investigating differences in Complex I in various cell types as it relates to pulmonary arterial hypertension (PAH).

Standard confocal versus super-resolution confocal microscopy of rat pulmonary artery smooth muscle cells. The ‘question mark’ mitochondria seen at the centre of the left image is actually three separate organelles. We are characterizing the mitochondrial network of various cell types and determining how this network is related to sensing changes in oxygen levels.

The Secret Lives of Mitochondria

Mitochondria are constantly dividing, fusing, and moving throughout your cells. That mitochondria do more than make energy is a relatively new observation, one that has given rise to the young field of mitochondrial dynamics.

“A Translational Journey”: A Special Panel Discussion about Queen’s CardioPulmonary Unit (QCPU)

vandusen — Mon, 18 Jun 2018 20:52:45 +0000

Cardiopulmonary diseases are the leading cause of death in Canada. Queen’s CardioPulmonary Unit (QCPU) – an 8,000 square foot translational research facility located in Queen’s Biosciences Complex – officially opened on October 6, 2017. Funded by a $7.7M joint award from the Canada Foundation for Innovation and the Ontario Ministry of Research, Innovation and Science, QCPU research focuses on the development, preclinical testing and commercialization of new therapies for heart, lung, blood and vascular (HLBV) diseases.
