Insulin secretion from pancretic β-cells becomes defective in all forms of diabetes mellitus. We and others have identified a subpopulation of β-cells termed “leaders” which exert disproportionate control over islet calcium dynamics. Leader β-cells are the first to experience an increase in intracellular calcium and a rise in glucose levels and drive recruitment of “follower” β-cells. Confocal images of a pancreatic islet undergoing a calcium wave. The cell nuclei are in magenta (DRAQ5). The Leader cell starts and spreads the calcium wave throughout the islet. The green signal reflects the calcium dynamics (GCaMP6f). Image produced at CR-CHUM cellular imaging facility.

This image reminds me of picture captured by helicopter from huge turnout in Berlin's demonstration against the islamic republic of Iran. it was the largest demonstration of Iranians in history following the death of Mahsa Amini. Women, Life, Freedom! Having cells separated in two different parts of the image is a reminder to me about where I came from, Iran, my contry of origion, where men and women were forced to be separated due to the country's rules.

Every patient's story awaiting a kidney transplant is a book just waiting to be opened and read. Faced with the opportunity to use marginal kidneys from older donors with diabetes or hypertension, a mosaic of emotions and questions emerges among patients over 65 awaiting a transplant. delving into their narratives, we understand that the true wealth of this quest and the desire to use such kidneys lies in their personal story, marked by the hope of improving their quality of life, the endless waiting, and the desire for better access to preemptive transplantation.

A clinical research nurse concludes her interview for tuberculosis screening with a resident in rural Madagascar. The data collected from such participants will be utilized by our team to better understand the social determinants associated with access to tuberculosis diagnosis. This will maximize the impact of modern technologies like whole-genome sequencing, used to study transmission and enhance disease control. At the end of the interview, the participant proudly shows us her small poultry (which she never parted with during the interview), a testament to our efforts in tuberculosis control.

Nanoparticles made of gold and silver alloy have specifically bound to proteins on SK-BR-3 breast cancer cells. These highly luminous nanoparticles enable us to encode each type of protein with a different color: blue, green, or orange. By a delightful coincidence, two cells expressing high levels of CD44, shown in green, form Mickey Mouse's ears and the tip of his tail, while his muscular body appears through the blue staining of the Her2 protein. The orange nanoparticles indicate the presence of the EpCAM protein here and there.

Six million Canadians suffer from arthritis. Nine hundred thousand Canadians suffer from fibromyalgia. Fibromyalgia and psoriatic arthritis share similar symptoms, can be confusing, or can coexist. This clinical overlap poses a challenge and can lead to misdiagnoses and mis-targeted treatments. Since October 2022, a team from the University of Montreal has been imaging the structure of certain tendons, including the Achilles tendon, using advanced ultrasound technologies to find an ultrasound signature that would distinguish between the two conditions. As of now, 2280 ultrasound images have been recorded.
