Summary: This study proposes the equine deep digital flexor tendon and its accessory ligament as a model to study the sliding mechanism between sub-tendons, demonstrating significant regional strain differences and greater force transmission from the accessory ligament to the tendon than vice versa. The results suggest that the distribution of load between sub-structures is highly dependent on their morphological relationship, which has important implications for understanding tendon mechanical behavior, injury mechanisms, and rehabilitation.

Summary: The study found that decellularized bovine tendon sheets (DBTS) had complete endotenon and epitenon, while decellularized tendon slices (DTS) only retained part of endotenon without epitenon. DBTS and DTS with thickness of 900 μm had complete fascicles, while DTS with less than 600 μm thickness had almost no complete fascicles. The DBTS and DTS with thickness of 900 μm showed similar ultimate tensile strength and stiffness to native tendon segments (NTSs).

Summary: The objective of this study was to present unprecedented radiological parameters for assessing the angle and inclination of the direct and indirect tendons of the proximal rectus femoris. The study found that there was inter- and intra-observer agreement in the measurements of these parameters, and there was population variability unrelated to demographic factors. These results are important for detecting risk factors for injuries in professional football and futsal players and other sports.

Summary: The systematic review compared the outcomes of Latissimus dorsi transfer (LDT) and pectoralis major transfer (PMT) for treating an irreparable subscapularis tendon tear. Results showed that LDT group had more significant improvements in various outcomes compared to the PMT group. Further evaluations with high-quality randomized controlled studies are required to determine the relative benefits of the two surgical approaches.

Summary: The study showed that ulnar slip flexor digitorum superficialis tendon transfer is effective in treating long-standing boutonniere deformities and achieving good functional outcomes, although minimal proximal interphalangeal joint extension deficits are inevitable due to chronicity and adaptive changes in the tissue.

Summary: This paper reviews the dislocation slip behavior of alpha phase in alpha, near alpha and alpha + beta titanium alloys dominated by alpha-Ti deformation under quasi-static loading, and discusses its relation with slip transfer, slip blocking, twinning and crack initiation. The slip behavior in Ti-alloys is analyzed in detail from the aspects of critical resolved shear stress (CRSS), grain orientation distribution and geometric compatibility factor m '. The interaction of slip behavior and interfaces is clarified systematically.

Summary: The study found a relationship between the number of FHL tendinous slips and toe flexor strength, with feet lacking FHL branching showing significantly lower strength in the third toe. Therefore, considering the number of FHL tendinous slips in an individual foot may have clinical implications for toe flexor rehabilitation or training.

Summary: In this study, a rolled rare earth magnesium alloy thin sheet was successfully prepared, and the plastic deformation mechanism and hardening mechanism were explored. The shape of the precipitates and the competition between local strain and macroscopic strain were found to affect the plastic deformation behavior of the alloy.

Summary: The transfer of basal-to-basal slip across grain boundaries was studied in weakly-textured pure Mg specimens deformed in tension using slip trace analysis and electron back-scatterer diffraction. Basal slip was the dominant deformation mechanism in most grains, and the transfer/blocking of slip at grain boundaries was examined. The active slip system(s) in the grains were determined by analyzing the rotation of grains caused by plastic slip along the basal slip systems. Additionally, the orientation of grain boundaries was measured to determine the twist angle theta.

Summary: This paper presents a quasi in-situ study on the plastic deformation behavior of high purity tantalum, focusing on slip activation and slip transfer. Key findings include the rotation degree and axes of grains involved in slip activation and transfer, as well as the lack of significant relationships between microstructural parameters and slip behavior. The study also highlights the importance of m' factors and Schmid factors in slip transfer, and the influence of various factors on the process.

Summary: This paper investigates the effect of blowing (transpiration flow) on hypersonic flow over a flat plate at different flow regimes. It studies the interaction between the free stream flow and transpiring gas introduced at the fluid-solid interface. The analysis considers flow conditions ranging from continuum to rarefied through transitional flow, and simulations are performed using the DSMC solver SPARTA. The results show variations in flow field properties and surface heat flux distribution due to transpiration and rarefaction effects.

Summary: This study investigates the development of the primary and secondary temporomandibular joints in humans, focusing on their coexistence and subsequent separation. The findings reveal that both joints develop simultaneously and remain connected for over 6 weeks before separating at around the 18th to 24th week. Understanding the precise timing and functional movements involved in the development of these joints is crucial for comprehending the overall development of the temporomandibular joint.

Summary: This study utilized 7 Tesla magnetic resonance imaging (MRI) to assess morphological and functional changes in skeletal muscle during exercise-induced delayed onset muscle soreness (DOMS). The results showed significant alterations in T2 signal intensity and T2 values immediately after exercise and 60 hours later. These findings suggest the potential use of ultra-high field MRI in sports medicine to monitor microstructural muscle damage and guide appropriate therapeutic strategies.

Summary: This study characterizes the morphology and topography of the spina musculi recti lateralis (SMRL) and compares it to known bony landmarks. The results show that the SMRL is a process of the sphenoidal orbital plate and serves as a reliable landmark for the insertion of the tendinous ring and lateral rectus. This is an important variation for orbital surgeons to be aware of.
