Techniques for arthroscopic partial-thickness and full-thickness RTC repairs continue to advance. When selecting an RTC repair technique, it is important to identify the tear pattern and adhere to the fundamentals of tendon mobilization and footprint preparation. Partial RTC tears greater than 50% in thickness can be reproducibly repaired with tear completion or transtendinous techniques with good clinical outcomes. Based on the available literature, small, less than 1-cm RTC tears can effectively be repaired with single-row techniques. Tears sized 1 cm to 3 cm can be repaired with either single-row, double-row, or transosseous-equivalent techniques based on surgeon comfort, tendon quality, and tissue mobility. Tears greater than 3 cm have shown superior results when transosseous-equivalent techniques are used. Further clinical studies are needed to definitively conclude the ideal RTC repair technique.

Enhanced post-thaw functional characteristics of cryopreserved caprine dermal fibroblasts through adhesion to extracellular matrix proteins.

Background: Extracellular matrix (ECM) proteins play a crucial role in regulating the biological properties of adherent cells. For cryopreserved fibroblasts, a favourable ECM environment can help restore their natural morphology and function more rapidly, minimizing post-thaw stress responses.
Methods And Results: This study explored the functional responses of cryopreserved enriched caprine adult dermal fibroblast (cadFibroblast) cells to structural [collagen-IV and rat tail collagen (RTC)] and adhesion ECM proteins (laminin, fibronectin, and vitronectin) under in vitro culture conditions.
A novel human pluripotent stem cell gene activation system identifies IGFBP2 as a mediator in the production of haematopoietic progenitors in vitro.

A major challenge in the stem cell biology field is the ability to produce fully functional cells from induced pluripotent stem cells (iPSCs) that are a valuable resource for cell therapy, drug screening, and disease modelling. Here, we developed a novel inducible CRISPR-mediated activation strategy (iCRISPRa) to drive the expression of multiple endogenous transcription factors (TFs) important for in vitro cell fate and differentiation of iPSCs to haematopoietic progenitor cells. This work has identified a key role for IGFBP2 in developing haematopoietic progenitors.

Remdesivir (RDV, Veklury®) is the first FDA-approved antiviral treatment for COVID-19. It is a nucleotide analogue (NA) carrying a 1'-cyano (1'-CN) group on the ribose and a pseudo-adenine nucleobase whose contributions to the mode of action (MoA) are not clear. Here, we dissect these independent contributions by employing RDV-TP analogues.

Introduction: Socioeconomic status (SES) affects access to care for traumatic rotator cuff (RTC) tears. Delayed time to treatment (TTT) of traumatic RTC tears results in worse functional outcomes. We investigated disparities in TTT and hypothesized that individuals from areas of low SES would have longer time to surgical repair.

We describe a surgical technique to repair medial meniscus posterior root tears through a transtibial pullout repair with a subcortical button for tibial fixation. This technique allows progressive tensioning of the repaired root without losing tension both during suturing of the knots above the button and after the procedure, owing to the specific button configuration.
