Article Abstract
Background: Varicocele (VC) is a significant contributor to both primary and secondary male infertility. VC can lead to progressive, time-dependent damage to testicular function, as demonstrated in both animal and human studies. To assess testicular tissue alterations, we conducted the first systematic review and meta-analysis on the effects of VC on testicular stiffness and volume. A literature search was conducted in June 2024 without language or geographic restrictions. The search included the databases PubMed, Embase, and Medline. We reviewed the literature to identify all published clinical trials using shear wave elastography (SWE) to evaluate the stiffness and volume of varicocele-affected and normal testes. The reference lists of the retrieved studies were examined. We conducted a systematic review and meta-analysis.
Results: Seven articles, encompassing 1118 testes, were selected from a pool of eighty-seven. The analysis revealed that the stiffness of varicocele-affected ipsilateral testes was higher than that of normal testes (p < 0.05), and the stiffness of normal testes was higher than that of contralateral testes (p < 0.05). Regarding volume, the varicocele-affected ipsilateral testes were smaller than the contralateral testes (p < 0.05), with no significant difference between the contralateral and normal testes (p > 0.05).
Conclusions: This meta-analysis indicates that VC impacts the stiffness and volume of both testes. SWE is an effective technique for assessing testes affected by VC, but a large-scale, multicenter randomized controlled study is needed for further confirmation.

Background: Vascular changes are observed in children with cystic fibrosis (cwCF), and gender-specific differences may impact arterial stiffness. We aimed to compare arterial stiffness and clinical parameters based on gender in cwCF and to determine the factors affecting arterial stiffness in cwCF.
Methods: Fifty-eight cwCF were included.

Hydrogel-based bioinks are widely adopted in digital light processing (DLP) 3D printing. Modulating their mechanical properties is especially beneficial in biomedical applications, such as directing cell activity toward tissue regeneration and healing. However, in both monolithic and granular hydrogels, the tunability of mechanical properties is limited to parameters such as cross-linking or packing density.

Breast, prostate and lung cancer cells frequently metastasize to bone, leading to disruption of the bone microstructure. This study utilized mechanical testing with micro-CT imaging, digital volume correlation (DVC), and atomic force microscopy (AFM) nanomechanical testing to examine the mechanical property variations in mouse long bones (tibia) with metastatic lung cancer cell involvement, spanning from the whole-bone scale to the microstructural level. In addition, we also investigated how metastatic invasion alters the morphology of hydroxyapatite nanocrystals in bone at the nanometer scale.

Imaging photoplethysmography (iPPG) is an emerging optical technique that allows for the contactless acquisition of arterial Blood Volume Pulse (BVP) signals from video recordings of the human skin. While iPPG offers a non-contact and convenient means for physiological monitoring, the accuracy of the extracted BVP signals remains limited. This limitation hinders its potential for advanced cardiovascular assessments, such as evaluations of arterial stiffness and cardiac function.

Atherosclerotic plaque rupture can lead to thrombotic cardiovascular events such as stroke and myocardial infarction. Computational models have shown that microcalcifications (calcified particles with a diameter < 50 μm) in the atherosclerotic plaque cap can increase cap tissue stresses and consequently contribute to plaque rupture. Microcalcification characteristics, such as particle size and volume fraction, have been implicated to affect cap stresses.
