Describing a Transition to Adult Type 1 Diabetes Care Model at the McGill University Health Centre.

Aims: To describe a type 1 diabetes melllitus (T1DM) transition care model by assessing clinic attendance, glycemic management, and diabetes-related hospitalizations.

Methods: This is a descriptive longitudinal single-center study of patients with T1DM aged 18 to 25 referred to our transition clinic from 2012 to 2021 (N=179).

Results: Our data analysis demonstrates an average clinic attendance rate of 79% and mean time between last pediatric and first adult visit of 6.

Tremelimumab and durvalumab as neoadjuvant or non-operative management strategy of patients with microsatellite instability-high resectable gastric or gastroesophageal junction adenocarcinoma: the INFINITY study by GONO.

Background: In resectable gastric/gastroesophageal junction adenocarcinoma (GAC/GEJAC), microsatellite instability (MSI-H) confers improved survival, but limited benefit from chemotherapy. Immunotherapy may eliminate the need of chemotherapy or surgery.

Patients And Methods: INFINITY is a multicentre, multicohort phase II trial (NCT04817826) investigating in Cohort 1 the activity and safety of tremelimumab+durvalumab (T300/D) as neoadjuvant treatment for dMMR/MSI-H, resectable GAC/GEJAC.

Prolonged cultivation enhances the stimulatory activity of hiPSC mesenchymal progenitor-derived conditioned medium.

Background: Human induced pluripotent stem cells represent a scalable source of youthful tissue progenitors and secretomes for regenerative therapies. The aim of our study was to investigate the potential of conditioned medium (CM) from hiPSC-mesenchymal progenitors (hiPSC-MPs) to stimulate osteogenic differentiation of human bone marrow-derived mesenchymal stromal cells (MSCs). We also investigated whether prolonged cultivation or osteogenic pre-differentiation of hiPSC-MPs could enhance the stimulatory activity of CM.

Diode and Selective Routing Functionalities Controlled by Geometry in Current-Induced Spin-Orbit Torque Driven Magnetic Domain Wall Devices.

Research on current-induced domain wall (DW) motion in heavy metal/ferromagnet structures is crucial for advancing memory, logic, and computing devices. Here, we demonstrate that adjusting the angle between the DW conduit and the current direction provides an additional degree of control over the current-induced DW motion. A DW conduit with a 45° section relative to the current direction enables asymmetrical DW behavior: for one DW polarity, motion proceeds freely, while for the opposite polarity, motion is impeded or even blocked in the 45° zone, depending on the interfacial Dzyaloshinskii-Moriya interaction strength.

Assessment of spinal cord injury using ultrasound elastography in a rabbit model in vivo.

The effect of the mechanical micro-environment on spinal cord injury (SCI) and treatment effectiveness remains unclear. Currently, there are limited imaging methods that can directly assess the localized mechanical behavior of spinal cords in vivo. In this study, we apply new ultrasound elastography (USE) techniques to assess SCI in vivo at the site of the injury and at the time of one week post injury, in a rabbit animal model.

Co-Culturing Human Adipose Derived Stem Cells and Schwann Cells on Spider Silk-A New Approach as Prerequisite for Enhanced Nerve Regeneration.

Fast recovery is crucial for a successful nerve repair and an optimal functional outcome after peripheral nerve injury. Regarding donor site morbidity, autologous transplantation shows great limitations, which urge the need for alternative options in nerve reconstruction. Spider silk was reported as an advantageous material for cell adhesion, migration and proliferation, and its use in conduits is of great interest, especially in combination with cells to improve nerve regeneration.

Surface-templated formation of protein microfibril arrays.

Ordered arrays of collagen microfibrils form rapidly and spontaneously from a solution of monomers deposited onto a mica substrate. These arrays are well-ordered and apparently continuous over the entire substrate. Correlated atomic force microscope images and Laué diffraction patterns indicate that the protein alignment and microfibril formation is controlled by the crystal orientation of the mica substrate rather than fluid flow or drying effects.
