This review surveys advances in constitutive models of AWT over the past two decades, with the aim of improving understanding of vascular mechanics and informing clinical practice. Five major computational frameworks are evaluated-elastic, viscoelastic, hyperelastic, structural solid models, and growth and remodeling (G&R) models-which collectively provide insights into stress-strain relationships and mechanobiological interactions under physiological and pathological conditions. Simple elastic formulations cannot capture the intrinsic nonlinearity of AWT. Nonlinear elastic and pseudo-elastic models are better suited for large deformations and anisotropy, especially under cyclic loading. Viscoelastic models effectively represent time-dependent responses to pulsatile blood flow. Structural solid models, including layered anisotropic, equivalent homogeneous, and generalized structure tensor formulations, predict the mechanical behavior of individual wall layers with high fidelity. Extending beyond instantaneous mechanics, G&R models embed these constitutive relations within higher-level frameworks to simulate long-term adaptations to altered hemodynamics, such as hypertension, aneurysm progression, or vascular graft remodeling. Future research should focus on developing dynamic models that more accurately simulate pulsatile loading, refining the characterization of AWT heterogeneity and anisotropy, and establishing multiscale and multi-physics frameworks to connect cellular processes with tissue-level behavior. Integrating big data and machine learning offers additional potential for robust parameter identification and predictive modeling. In conclusion, this review provides a comprehensive evaluation of AWT constitutive modeling, from fundamental elasticity-based approaches to advanced G&R frameworks. By identifying limitations and outlining future directions, it highlights the role of biomechanics in advancing personalized medicine, improving CVD diagnosis and treatment, and promoting deeper understanding of disease mechanisms.</p>","PeriodicalId":54554,"journal":{"name":"Progress in Biophysics & Molecular Biology","volume":" ","pages":""},"PeriodicalIF":4.5,"publicationDate":"2025-12-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145795380","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, success increasingly depends on achieving rapid, uniform warming to avoid devitrification: the critical warming rate (CWR) required is often orders of magnitude higher than the critical cooling rate (CCR). Conventional convective thawing (e.g., water baths) produces edge-to-core thermal gradients that can lead to lethal ice formation in larger or more complex samples. Suboptimal warming disrupts cellular ultrastructure, leading to meiotic spindle collapse, mitochondrial depolarization, reactive oxygen species production, DNA damage, and apoptosis. These changes manifest as impaired embryo development and the formation of necrotic tissue cores. Notably, lipid-rich porcine oocytes and embryos are particularly susceptible to recrystallization during slow warming, with higher fragmentation and lower viability than their bovine and ovine counterparts. This review synthesizes thermophysical principles underlying the CWR requirement and biological evidence of the warming bottleneck across animal systems. This thermophysical imbalance means that rewarming, rather than cooling, is the decisive barrier to successful vitrification. We then discuss emerging volumetric rewarming technologies that uniformly deliver energy: magnetic nanoparticle-induced nanowarming, laser-driven photothermal heating, dielectric (radiofrequency/microwave) rewarming, and ultrafast Joule (ohmic) heating. These methods have demonstrably exceeded CWR thresholds in embryos, tissues, and organs, improving cell survival and function. We also highlight enabling tools such as microfluidic cryoprotectant (CPA) handling, automated vitrification platforms, artificial intelligence (AI)-guided protocol optimization, and isochoric (constant-volume) vitrification, which collectively enhance reproducibility and scalability of cryopreservation workflows. In conclusion, integrating volumetric heating modalities with these engineering innovations promises to transform animal cryopreservation: uniformly rapid warming will improve immediate post-thaw viability and preserve biological integrity, enabling routine, large-scale germplasm banking for livestock production and conservation.</div></div>","PeriodicalId":54554,"journal":{"name":"Progress in Biophysics & Molecular Biology","volume":"199 ","pages":"Pages 31-45"},"PeriodicalIF":4.5,"publicationDate":"2025-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145679604","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, existing literature lacks an integrated framework for predicting when crowding will favor productive assembly versus drive pathological outcomes—a gap that has hindered both mechanistic understanding and therapeutic development. This review examines how macromolecular crowding—an intrinsic feature of the intracellular environment—shapes protein aggregation outcomes by modulating key physicochemical parameters: volume exclusion, electrostatic interactions, aggregate morphology, cytoplasmic viscosity, and liquid–liquid phase separation. We demonstrate that crowding acts not as a universal promoter or inhibitor of aggregation, but rather as a context-dependent modulator that amplifies latent vulnerabilities in proteins predisposed to misfolding while facilitating productive assembly in properly regulated systems. By analyzing the mechanistic continuum between functional and pathological aggregation, we provide a framework for interpreting how identical molecular forces yield divergent biological outcomes depending on protein properties, environmental conditions, and cellular regulation. This perspective clarifies how the intracellular milieu governs aggregation dynamics and identifies promising avenues for therapeutic intervention, including strategic modulation of crowding conditions to promote protective assemblies while suppressing toxic aggregates in misfolding-related diseases. We conclude by outlining future directions toward quantitative, predictive models that integrate molecular mechanism with physiological context, bridging the gap between in vitro biophysics and in vivo cellular function.</div></div>","PeriodicalId":54554,"journal":{"name":"Progress in Biophysics & Molecular Biology","volume":"199 ","pages":"Pages 79-98"},"PeriodicalIF":4.5,"publicationDate":"2025-12-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145679540","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
