Summary: This study investigates the fatigue and corrosion-fatigue crack initiation in coldpilgered Sanicro 28 super austenitic stainless steel. Through stress-controlled symmetric reverse bending fatigue tests, combined with electrochemical experiments and advanced microstructural analyses, the damage characteristics of the material were examined in detail. It was found that the planar character of dislocation substructure led to a more homogenous distribution of strain, which delayed the accumulation of damage. The formation of the insoluble and stable MoO3 oxide increased the rate of repassivation, providing resistance against the attack of chloride ions. The corrosion fatigue behavior under different test frequencies was discussed based on the synergistic effects of mechanical and environmental damages.

Summary: The influence of extrusion temperature on the microstructure, mechanical properties, and low-cycle fatigue (LCF) properties of commercial AZ91 and nonflammable SEN9 alloys was investigated. The materials extruded at 300°C exhibited finer grains and increased compressive yield strength compared to those extruded at 400°C. In LCF tests, 400°C extruded materials showed lower stress-activated twinning and longer fatigue lives. A fatigue life prediction model based on total strain energy density and the number of cycles to fatigue failure was established for both alloys.

Summary: The study found that corrosion has a significant impact on the ULCF properties and fracture mechanism of structural steel. The ULCF fracture life of corroded specimens decreases with increasing surface roughness, and the crack-initiation life is less than half of the fracture life. As the corrosion degree increases, the area of the ULCF crack propagation zone expands significantly, showing a transition from ductile to brittle fracture mode.

Summary: Osteoporosis is a metabolic skeletal disorder characterized by reduced bone mineral density and microstructural destruction, leading to increased fracture risk. Current medicines have limitations and potential side effects, prompting the search for natural alternatives. Icariin, derived from a traditional Chinese medicine, has shown promise in reducing bone loss in osteoporosis with relatively low side effects. It acts through various mechanisms, including promoting bone formation and suppressing bone resorption. While the underlying mechanisms are not fully understood, icariin could be a viable option for improving osteoporosis.

Summary: Intervertebral disc degeneration (IDD) is a major cause of low back pain (LBP) and disability in the elderly, resulting in a significant global public health and economic burden. The mechanisms of IDD are complex and the specific targets for reversing IDD remain unclear. Interleukin-1 beta (IL-1 beta), a key mediator of IDD, has been found to regulate IVD cell death through various mechanisms, including apoptosis, pyroptosis, and ferroptosis. Inhibition of IL-1 beta has shown promise as a biological therapy for IDD by inhibiting inflammatory processes and regulating ECM degradation. This article reviews the mechanisms and functions of IL-1 beta in IDD and explores advances in IL-1 beta inhibition as a potential biotherapeutic approach for disc degeneration.

Summary: Osteoarthritis (OA) is a debilitating disease with significant economic and social burden. Cartilage injury, characterized by excessive chondrocyte death, inflammation, abnormal bone metabolism, and imbalance of extracellular matrix, presents a major pathological feature of OA. Mesenchymal stem cells-derived extracellular vesicles (MSCs-EVs) have shown promise as both early diagnostic biomarkers and therapeutic strategies for OA, due to their important role in intercellular communication. This paper comprehensively reviews the functions and mechanisms of MSCs-EVs in cartilage repair, highlighting their potential in protecting chondrocyte death, regulating bone metabolism, balancing extracellular matrix metabolism, alleviating inflammation, and regulating angiogenesis.

Summary: In this paper, a scale-relation joint decoupling network (SRJDN) is proposed for the semantic segmentation of remote sensing (RS) images, which considers decoupling scales and decoupling relationships to explore more complete relationships of multiscale RS objects. The SRJDN consists of three steps: scale decoupling (SD), relation decoupling (RD), and fine-granularity guided fusion (FGF). Experimental results on two large-scale fine-resolution RS image datasets demonstrate the effectiveness and robustness of the proposed joint decoupling strategy and the FGF module in RS image semantic segmentation tasks.

Summary: The study reveals the surface-initiated rolling contact fatigue (RCF) failure mechanism under heavy load and initial high roughness surface. The results indicate that precursor of collapsed morphology and nanocrystalline layer are the main factors causing lower RCF life with high roughness compared to low roughness surfaces. The spalling failure initiating from low roughness surface under heavy load is strongly dependent on surface plastic deformation.

Summary: This study investigates the competitive relationship between fretting fatigue and plain fatigue in press-fitted railway axles. By changing the depth of the stress relief groove, the plain fatigue limit and fretting fatigue strength were tested. Detailed information was gathered, and an evaluation methodology integrating finite element simulation and the Modified Wohler Curve Method was established. The study concludes that the optimal groove depth, which balances the anti-fatigue capabilities, depends on the number of test cycles.
