Many biological fibrous tissues exhibit distinctive mechanical properties arising from their highly organized fibrous structure. In disease conditions, alterations in the primary components of these fibers, such as type I collagen molecules in bone, tendons, and ligaments, assembly into a disorganized fibers architecture generating a weak and/or brittle material. Being able to quantitatively assess the fibers orientation and organization in biological tissue may help improve our understanding of their contribution to the tissue and organ mechanical integrity, and assess disease progress and therapy effect.

Background: The recent wave of clinical trials of psychedelic substances among patients with life-limiting illness has largely focused on individual healing. This most often translates to a single patient receiving an intervention with researchers guiding them. As social isolation and lack of connection are major drivers of current mental health crises and group work is expected to be an important aspect of psychedelic assisted psychotherapy, it is essential that we understand the role of community in psychedelic healing.

The trimeric intracellular cation channel B (TRIC-B), encoded by TMEM38B, is a potassium (K) channel present in the endoplasmic reticulum membrane, where it counterbalances calcium (Ca) exit. Lack of TRIC-B activity causes a recessive form of the skeletal disease osteogenesis imperfecta (OI), namely OI type XIV, characterized by impaired intracellular Ca flux and defects in osteoblast (OB) differentiation and activity. Taking advantage of the OB-specific Tmem38b knockout mouse (Runx2Cre;Tmem38b; cKO), we investigated how the ion imbalance affects the osteogenetic process.

Viral variant and host vaccination status impact infection with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), yet how these factors shift cellular responses in the human nasal mucosa remains uncharacterized. We performed single-cell RNA sequencing (scRNA-seq) on nasopharyngeal swabs from vaccinated and unvaccinated adults with acute Delta and Omicron SARS-CoV-2 infections and integrated with data from acute infections with ancestral SARS-CoV-2. Patients with Delta and Omicron exhibited greater similarity in nasal cell composition driven by myeloid, T cell and SARS-CoV-2 cell subsets, which was distinct from that of ancestral cases.
