The Scapholunate (S-L) and Lunotriquetrum (L-Tr) ligaments have been extensively studied in the literature. A wide range of measurements has been reported for ultimate load and stiffness with different mechanical protocols. In this study, we examined the mechanical properties of both ligaments harvested from the same wrist. Fifteen fresh cadaver wrists were used to harvest eight S-L and four L-Tr. Testing was performed in quasi-static loading in a well defined direction for each ligament system. The ultimate load for S-L was 68-210 N with a mean value of 147 ± 54 N and a stiffness of 35.7 ± 9.6 N/mm. For L-Tr the ultimate load was 122-179 N with a mean value of 150 ± 24 N and a stiffness of 192 ± 60 N/mm. The two ligaments had nearly the same ultimate load, but the L-Tr had a higher stiffness (p = 0.05). These findings could be useful to assess the appropriate autologous autografts for reconstruction of the S-L and L-Tr.

Purpose: This study aimed to compare the biomechanical properties of four meniscal suture configurations-two simple sutures (TSS), two cinch sutures, a locking loop stitch (LLS), and a delta-grip stitch (DGS)-for transtibial pullout repair of medial meniscus posterior root tears (MMPRTs) using porcine menisci.
Methods: Forty porcine menisci were randomly assigned to each suture configuration with all-inside repair. All specimens were subjected to cyclic loading for 1000 cycles, followed by a load-to-failure test.

Recombinant adeno-associated viruses (rAAVs) have emerged as promising vaccine vectors due to their enduring efficacy with a single dose. However, insufficient cellular immune responses and the random and non-specific distribution of AAVs post-injection may hinder the development of AAV vaccines. Here, a novel Pickering emulsion platform stabilized by biomineralized manganese nanoparticles and aluminum hydroxide, which can rapidly and efficiently load AAVs, is reported.

Trust in healthcare providers plays a significant role in adhering to ART and is likely lower among Black WLHIV compared to their White counterparts. This study examined the relationship between experienced stigma in healthcare settings and ART adherence and viral suppression through anticipated stigma in healthcare settings, internalized stigma, and medical mistrust.

Concrete-filled double-skin steel tubular (CFDST) columns have become widely utilized in building construction and bridges, thanks to their exceptional structural capabilities. Therefore, this study investigates the axial compressive behavior of square CFDST columns. The study aims to explore the influence of external and internal plate shapes (flat or corrugated plates) and different widths of internal steel tubes on the axial compressive behavior.

Latency in flux observation has an adverse effect on the performance of observer-based field-oriented speed control for three-phase induction motor (IM). The reduction of the convergent rate of estimation errors could improve the performance of speed-controlled IM based on flux observers. The main contribution is to design a fast convergent flux observer, which provides bounded estimation error immediately after one instant of motor startup.
