Objective: To explore the efficacy and outcomes of the ‘Inverted V graft’ technique, which synergistically combines a columellar strut and an extension graft. This innovative approach aims to provide enhanced structural support and improved aesthetic results in rhinoplasty procedures. Methods: Patients were observed postoperatively over a period of one year, with evaluations at designated intervals using the Rhinoplasty Outcome Evaluation (ROE) questionnaire to assess satisfaction. The closed preservation rhinoplasty method was employed under general anesthesia with all patients. The Inverted V graft was meticulously sutured in place, augmenting nasal structure and stability. Results: In a group of 19 participants, the study observed significant enhancements in patient satisfaction post-rhinoplasty, as indicated by ROE scores, with no age-related variation in outcomes. Surgical times averaged around 209.5 min, with an 18-month follow-up showing similar satisfaction improvements across both genders. Conclusions: The study demonstrates that the dual-purpose Inverted V graft technique significantly enhances structural support and aesthetic outcomes in rhinoplasty procedures. The use of this technique resulted in substantial improvements in patient satisfaction, as measured by the Rhinoplasty Outcome Evaluation (ROE) scores, indicating its effectiveness in achieving desired surgical results.

T-2 toxin, a mycotoxin produced by the genus Fusarium, is widely prevalent in agricultural products and livestock feed, posing substantial health risks to livestock and humans. This toxin induces oxidative stress in testicular Sertoli cells, disrupts testicular architecture, and compromises spermatogenesis. Despite its widespread presence in contaminated feeds, effective therapeutic strategies to counteract T-2 toxin-induced reproductive toxicity in Sertoli cells remain elusive. This study evaluated the protective efficacy and molecular mechanisms of proanthocyanidins (PCs), a phytochemical with antioxidant properties, against T-2 toxin-induced damage in yak (Bos grunniens) Sertoli cells. The findings revealed that T-2 toxin markedly reduced the viability of yak Sertoli cells and stimulated the production of reactive oxygen species (ROS). Treatment with 10 μg/mL PCs significantly enhanced cell viability, decreased apoptosis, and preserved cellular functions. Furthermore, PCs reduced ROS levels in yak Sertoli cells exposed to T-2 toxin and improved antioxidant capacity by upregulating the nuclear factor erythroid derived 2-like (NRF2)/heme oxygenase-1 (HO-1) signaling pathway. Additionally, PCs inhibited mitochondria-mediated apoptosis, diminished the occurrence of malformed mitochondria, and enhanced the sirtuin 1 (SIRT1)/peroxisome proliferator-activated receptor gamma coactivator 1 alpha (PGC-1α) signaling pathway associated with mitochondrial biogenesis in yak Sertoli cells exposed to T-2 toxin. This study provides novel insights into the prevention and treatment of T-2 toxin-induced reproductive damage in yaks and underscores the potential application of PCs in this context. Full article

by Elisabetta Abruzzese, Malgorzata Monika Trawinska, Simona Bernardi, Alessandra Checcoli and Martina Canichella
Cancers 2026, 18(9), 1370; https://doi.org/10.3390/cancers18091370 (registering DOI) - 25 Apr 2026
Abstract
Myelofibrosis (MF) is a chronic myeloproliferative neoplasm characterized by progressive bone marrow fibrosis, extramedullary hematopoiesis (particularly symptomatic splenomegaly), constitutional symptoms, progressive cytopenias, and, in a subset of patients, leukemic transformation.

Myelofibrosis (MF) is a chronic myeloproliferative neoplasm characterized by progressive bone marrow fibrosis, extramedullary hematopoiesis (particularly symptomatic splenomegaly), constitutional symptoms, progressive cytopenias, and, in a subset of patients, leukemic transformation. The advent of the JAK1/2 inhibitor ruxolitinib has revolutionized the management of MF, substantially improving splenomegaly, symptom burden, and, in some settings, overall survival. However, a substantial percentage of patients fail to achieve sustained benefit, are intolerant, or become refractory; real-world and clinical trial data indicate that approximately half of treated patients discontinue ruxolitinib treatment within 3 years and up to approximately 75% within 5 years, with poor outcomes after discontinuation (median survival in several series is approximately 12–14 months). In recent years, several new small molecules that act beyond the JAK-STAT axis have emerged in clinical development. These include agents targeting telomerase (imetelstat), epigenetic regulation via BET inhibition (pelabresib/CPI-0610), the MDM2-p53 axis (navtemadlin/KRT-232), erythroid maturation and the bone marrow microenvironment (luspatercept), PI3K signaling (parsaclisib), and PIM inhibitors (nuvisertib). Early clinical data show promising results for symptom and splenic control in specific settings and, importantly, suggest potential disease-modifying activity (improvements in marrow fibrosis and molecular responses) for some compounds. This review summarizes the biological rationale, key clinical data (efficacy and safety), ongoing randomized trials, and remaining knowledge gaps for these non-JAK small molecules in MF and offers practical considerations for integrating them into contemporary treatment algorithms.

Background/Objectives: Fenestrated and branched endovascular aortic repair (F/BEVAR) is increasingly used for the treatment of complex aortic aneurysms, and is traditionally performed under general anesthesia (GA). Data on the use of local anesthesia (LA) for F/BEVAR remain limited. This study aimed to report early outcomes of F/BEVAR performed under LA versus GA, with a focus on feasibility and perioperative complications in a high-risk patient population. Methods: This single-center retrospective analysis included patients undergoing F/BEVAR under LA or GA. Primary outcomes were in-hospital mortality and in-hospital complications. Secondary outcomes included early reintervention, intensive care unit and hospital length of stay, blood transfusion requirements, and technical success. Results: A total of 359 patients were included, of whom 25 (7.0%) were treated under LA and 334 (93.0%) under GA. Conversion from LA to GA occurred in 6 patients (24%). Patients in the LA group represented a higher-risk cohort, with advanced age, higher ASA class, larger aneurysm diameters, and a greater proportion of emergency and ruptured repairs. Technical success was high, and procedural metrics were within expected ranges. In-hospital mortality was numerically higher in the LA group (12.0% vs. 2.9%, p = 0.05). Overall, in-hospital complications were more frequent in the LA group (68.0% vs. 41.3%, p = 0.009), including a higher rate of spinal cord ischemia (24.0% vs. 8.5%, p = 0.02). Blood transfusion requirements were also greater in patients treated under LA (p = 0.004), while blood loss, ICU stay, and hospital length of stay were comparable. Early reintervention occurred more frequently in the LA group (31.8% vs. 10.4%, p = 0.009). Conclusions: LA appears feasible in selected high-risk patients undergoing complex F/BEVAR. However, given substantial baseline differences between groups, no conclusions can be drawn regarding comparative safety or efficacy relative to GA. These findings should be considered preliminary.

Hesperidin, a flavonoid abundantly found in citrus fruits, has demonstrated a substantial role in the management of various pathogeneses. Furthermore, the wide range of health-promoting properties of hesperidin, including antioxidant, anti-inflammatory, anti-cancerous, hepatoprotective, neuroprotective, nephroprotective, and cardioprotective effects, has been well documented. Additionally, persuasive evidence from both in vivo and in vitro studies highlights its substantial roles in combating obesity, protecting the kidneys, liver, and lung tissue architecture, promoting wound healing, and modulating immune responses. This flavonoid acts as an effective antimicrobial agent against a wide range of microorganisms by inhibiting biofilm formation and disrupting the cell membrane. This review aims to deliver comprehensive insights into the therapeutic potential of hesperidin across different pathogenesis through distinct mechanisms. Moreover, it provides up-to-date evidence on the synergistic properties of this compound with other drugs as well as compounds, and emerging plans to enhance its efficiency in health management through various nanoformulation approaches. Despite its considerable therapeutic potential, the clinical application of hesperidin remains constrained by poor bioavailability, rapid degradation, and dosage-related limitations. Addressing these challenges will require extensive further research to clarify its mechanisms of action, safety profile, and therapeutic efficacy in managing underlying pathogenic conditions.

Human adenovirus type 7 (HAdV-7) is a significant pathogen responsible for viral community-acquired pneumonia in children. To date, no specific antiviral agents have been approved for clinical use against HAdV infections. Traditional Chinese medicine (TCM) mixtures have shown promising potential in managing viral pneumonia. This study aimed to evaluate the antiviral activity of Yuanzhixingrenheji (YZ), a hospital-prepared TCM formulation from Beijing Children’s Hospital, against HAdV-7. Initial screening of four hospital formulations (Feiyanheji, Qingjieheji, Yindaizhikeheji, and Yuanzhixingrenheji) using a CCK-8 assay revealed that YZ exhibited the lowest cytotoxicity. In vitro, YZ pretreatment and post-infection treatment exhibited dose-dependent antiviral activity against HAdV-7 in A549 cells, significantly suppressing the DBP mRNA level and protein expression while reducing viral genome copies, HAdV-7-GFP fluorescence, hexon fluorescence, and DBP nuclear localization. In the hDSG2+/+ C57BL/6 mouse model of HAdV-7 infection, YZ effectively mitigated infection-induced body weight loss and substantially reduced viral loads in lung tissue. Furthermore, a clinical retrospective analysis indicated that YZ treatment significantly decreased post-hospitalization serum C-reactive protein levels of pediatric patients with HAdV infection in various disease severities. Compared with conventional treatment, YZ treatment also significantly reduced peak temperature and shortened the duration of fever in children with HAdV infection, supporting its therapeutic potential. In summary, this study provides the first integrated evidence from in vitro, in vivo, and clinical retrospective investigations, demonstrating that the TCM mixture YZ has significant anti-HAdV-7 activity and clinical efficacy. Characterized by a favorable safety profile and low economic burden, YZ is a promising candidate for the treatment of pediatric adenovirus pneumonia. Full article

Matrix metalloproteases (MMPs), which are activated during malignancy growth and metastasis, have been a focus of current anticancer research and development. The selective recognition and precise inhibition of active MMPs could limit cancer progression. Photodynamic therapy (PDT) is a well-established local treatment for solid tumors. MMPs are expressed primarily in the vicinity of the tumor, and PDT strongly influences this process. However, in rare cases, PDT can activate MMPs. An improved PDT outcome was observed with the action of an MMP inhibitor (MMPI), namely Prinomastat. Research on this topic remains limited, presenting a substantial opportunity for further investigations. Various small-molecule compounds have been designed to target MMPs as potential inhibitors, but clinical trials have not confirmed their efficacy in vitro or in vivo. Currently, novel MMPIs with complex chemical structures are being designed and have shown high efficacy in initial preclinical studies. This review aims to provide a critical overview of recent advances in the use of cancer-related MMPs as therapeutic targets, along with new innovative approaches to targeting them. The effects of PDT on cancer-related MMPs, along with the advantages of combining therapies that could enhance curative efficacy, are discussed. The novel inhibitory approaches that regulate cancer-related MMPs are summarized. Full article

Importance: Triple-negative breast cancer (TNBC) is characterized by high tumor mutation burden and frequent programmed cell death ligand 1 (PD-L1) expression, making immune checkpoint inhibitors (ICIs) a promising therapeutic approach. However, randomized trials of chemoimmunotherapy (Chemo-IO) in locally recurrent unresectable or metastatic TNBC have shown inconsistent results, necessitating a clearer understanding of efficacy and patient selection. Objective: The aim of this study was to evaluate the efficacy and safety of chemotherapy combined with immunotherapy vs. chemotherapy alone in patients with locally recurrent unresectable or metastatic triple-negative breast cancer and to identify beneficiary populations to guide optimal treatment selection. Data Sources: PubMed, Embase, and the Cochrane Library were searched from database inception through 23 August 2025. Study Selection: Randomized clinical trials (RCTs) comparing chemotherapy combined with ICIs vs. chemotherapy with placebo or control in patients with locally recurrent unresectable or metastatic TNBC were selected. Data Extraction and Synthesis: Two investigators independently performed data extraction and assessed risk of bias using the Cochrane Risk of Bias 2 tool (RoB 2). Heterogeneity was evaluated using the I2 statistic. Data were synthesized using random-effects meta-analysis models to calculate hazard ratios (HRs) for time-to-event outcomes and risk ratios (RRs) for dichotomous outcomes according to the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guidelines. Results: Seven RCTs comprising 3485 patients (2085 in the Chemo-IO group, 1400 in the control group) were included. The median age across trials ranged from 52 to 57 years. Chemo-IO significantly improved PFS (HR, 0.82 [95% CI, 0.76–0.89]; p < 0.01) and OS (HR = 0.88; 95% CI: 0.81–0.96; p = 0.004) in the intention-to-treat (ITT) population, with PFS benefit particularly evident in PD-L1-positive patients (HR = 0.68, 95% CI: 0.59–0.79). However, OS improvement in the PD-L1-positive subgroup was not statistically significant. CBR did not differ significantly in the intention-to-treat population (RR, 1.11 [95% CI, 0.99–1.25]; p =  0.08) but was higher in PD-L1-positive patients (RR, 1.15 [95% CI, 1.01–1.31]; p = 0.04). Safety analyses revealed no significant differences in overall AE (RR, 1.01 [95% CI, 0.99–1.02]; p = 0.35), TEAE (RR, 1.01 [95% CI, 0.99–1.03]; p = 0.19), or grade ≥ 3 TEAE (RR, 1.00; [95% CI, 0.93–1.07]; p =  0.98). However, serious AE (RR, 1.32 [95% CI, 1.11–1.57]; p = 0.001) and irAE (RR, 1.86 [95% CI, 1.41–2.45]; p <  0.01) were more frequent with Chemo-IO. Conclusions and Relevance: Chemotherapy combined with immunotherapy significantly improved PFS and OS in patients with locally recurrent unresectable or metastatic TNBC, without substantially increasing chemotherapy-related toxicities. However, the OS benefit in PD-L1-positive patients was not statistically significant, and the combined regimen was associated with higher rates of serious and immune-related adverse events. These findings support the use of Chemo-IO as a treatment option, highlighting the importance of PD-L1 status and careful monitoring of immune-mediated toxicities in clinical practice. Full article

Transfer Learning from Homogeneous to Heterogeneous: Fine-Tuning a Pretrained Interatomic Potential for Multicomponent Mo Alloys with Localized Substitutional Alloying
by Lixin Fang, Liqin Qin, Limin Zhang, Hao Zhou, Xudong He, Zekun Ren, Tongyi Zhang and Yi Liu

Machine learning interatomic potentials (MLIPs) are typically developed for globally ordered homogeneous systems (GOHomS), which exhibit only minor local deviations from equilibrium configurations.

Machine learning interatomic potentials (MLIPs) are typically developed for globally ordered homogeneous systems (GOHomS), which exhibit only minor local deviations from equilibrium configurations. Consequently, most existing MLIPs trained on GOHomS often perform inadequately when applied to locally ordered heterogeneous systems (LOHetS), e.g., substitutional alloying elements in multicomponent alloys. To describe doping alloy systems, we develop a fine-tuned MLIP based on the MACE foundation model, specifically tailored for Mo-based dilute alloys containing one or two out of 20 substitutional elements: Cr, Fe, Mn, Nb, Re, Ta, Ti, V, W, Y, Zr, Al, Zn, Cu, Ag, Au, Hg, Co, Ni, and Hf. The model is built on more than 7000 equilibrium and non-equilibrium structures derived from first-principles density functional theory (DFT) calculations. The optimized large-scale fine-tuned model attains state-of-the-art accuracy, with a mean absolute error (MAE) and root-mean-square error (RMSE) of 2.27 meV/atom and 3.79 meV/atom for energy predictions, and 13.83 meV/Å and 24.26 meV/Å for force predictions, respectively. Systematic evaluation under different data-splitting protocols shows that unknown element extrapolation remains challenging under strict dopant hold-out, whereas substantially improved accuracy can be achieved in partial-exposure transfer settings. The fine-tuned models reduce the MAE by approximately 7–10 times compared to models trained from scratch, and by 10–20 times relative to zero-shot foundation models. This performance gain remains consistent across varying dataset sizes (equilibrium vs. non-equilibrium structures) and model scales. Our work illustrates the efficacy of transfer learning from globally ordered homogeneous systems to locally ordered heterogeneous multicomponent alloy environments. However, direct transfer to entirely unknown elements remains challenging, especially when proxy embeddings are employed without fine-tuning. Thus, to achieve high accuracy without incurring additional cost, it is essential to include unknown elements in the training dataset while minimizing the number of configurations containing known elements. Moreover, the current findings are primarily validated for dilute Mo-based alloy systems. Extending this approach to more compositionally complex alloy spaces may necessitate additional data and further fine-tuning. Full article

To address the shortcomings of the information acquisition optimizer (IAO)—specifically its susceptibility to premature convergence, insufficient exploitation capability during later stages, and population diversity decay when applied to complex optimization problems—this paper proposes a multi-strategy improved information acquisition optimizer (MIIAO). Centered on balancing exploration and exploitation capabilities during the search process, this method incorporates several key strategies: an adaptive differential perturbation factor is designed to dynamically adjust the search step size; an elite-guided information acquisition mechanism is introduced to enhance convergence efficiency within high-quality regions; a diversity-based restart perturbation strategy is integrated to mitigate the risk of entrapment in local optima; and a mirror boundary handling technique is adopted to bolster the resilience of solutions near boundaries and improve the effectiveness of searching within the feasible domain. To validate the efficacy of the proposed method, MIIAO was applied to the CEC2014, CEC2017, and CEC2022 benchmark test suites and systematically compared against various representative intelligent optimization algorithms. Furthermore, the method was applied to multi-threshold image segmentation tasks based on Otsu’s criterion. Experimental results demonstrate that MIIAO consistently exhibits superior solution accuracy, convergence speed, stability, and statistical ranking across various dimensions and a diverse range of complex test functions; the results of the Wilcoxon rank-sum test and Friedman mean ranking further substantiate its comprehensive performance advantages. In the image segmentation experiments, MIIAO achieved superior Otsu objective function values across multiple test images and under various threshold settings, while also demonstrating higher segmentation quality and greater robustness across evaluation metrics such as PSNR, SSIM, and FSIM. In summary, the proposed MIIAO effectively enhances the original IAO’s global search capability, local exploitation capability, and ability to maintain population diversity, thereby demonstrating significant potential for practical application in both numerical optimization and multi-threshold image segmentation tasks.

Background: Oxidative liver damage, fibrosis, cirrhosis and liver failure are caused by reactive oxygen species and inflammatory responses triggered by bile retention during prolonged cholestasis. Pomegranate and persimmon fruits, which are loaded with bioactive compounds that have anti-inflammatory and antioxidant properties, were evaluated separately for their efficacy in preventing oxidative stress and inflammation in cholestasis. Methods: Pomegranate and persimmon juices were analyzed for their vitamin C, carotenoids and organic acid levels, phenolic profile, and antioxidant activity. Liver protection against oxidative stress and inflammation brought on by cyclosporine-induced cholestasis in rats was verified by biochemical measurements, metabolite identification, and histopathologic examination. To forecast the mechanism of pomegranate and persimmon anti-inflammatory action, an in silico assessment was also carried out. Results: Vitamin C levels in pomegranate and persimmon juices were 99.55 and 51.75 µg/g, respectively. In both pomegranate and persimmon juices, gallic acid was the most prevalent phenolic compound (123.20 and 50.69 µg/g, respectively). Pomegranate and persimmon juices significantly (p < 0.05) reduced the rise in liver values of MDA, NO, TNF-α, IL-6, IL-1β, and TLR4, as well as serum values of total and direct bilirubin caused by cyclosporine. Additionally, the alteration of metabolites, particularly amino acids, demonstrated the inhibitory effect of pomegranate and persimmon juices on liver damage. Gallic acid’s and catechin’s substantial binding affinities with target inflammatory cytokines (TNF-α and TLR4) were further validated by molecular docking. Conclusions: These results showed that pomegranate and persimmon juices mainly modulated inflammation and oxidative stress to provide hepato-protective benefits against cyclosporine-induced cholestatic liver injury.

Olive tree (Olea europaea L.) is a major Mediterranean crop, valued for both fruit yield and high-quality oil, yet extreme summer stress, including high temperature, intense irradiance, and water limitation, can substantially reduce productivity and affect oil composition. The objective of the present study was to evaluate the mitigating efficacy of foliar applications of glycine betaine (GB), kaolin (K), and calcium carbonate (CC) under rainfed conditions across three Greek sites on “Koroneiki” (in two sites) and “Lianolia Kerkyras” (in one site) cultivars. Treatments were applied during the summer, and effects on fruit yield, oil content per fruit, oil yield per tree, and key oil quality parameters—including total phenols, flavonoids, antioxidant capacity, and fatty acid composition—were assessed. GB significantly enhanced fruit yield and oil production for “Koroneiki” at the site with the harshest environmental conditions (24.37 Kg fruits per tree and 4.69 Kg of oil per tree compared to 19.16 Kg fruits per tree and 3.48 Kg of oil per tree in control). In contrast, K proved most effective at the other two sites for both cultivars (43% and 52.8% increase in fruit yield and oil mass per tree in “Koroneiki” respectively and 30% as well as 34% increase in yield and oil mass per tree in “Lianolia Kerkyras”, respectively. CC exhibited limited impact on both productivity and quality. Under all treatments, the oils produced could be classified as extra virgin olive oils, with the products exhibiting minor effects on the functional properties of the oils. These findings indicate that the efficacy of stress-alleviating foliar treatments is strongly influenced by both environmental conditions and cultivar. Overall, K was the most effective treatment, followed by GB. Tailored application of these treatments represents a sustainable approach to maintaining olive productivity and preserving oil quality in the context of climate change. Full article

Background: The global aging population faces an increasing prevalence of type 2 diabetes mellitus (T2DM), often complicated by frailty, cognitive decline, and impaired manual dexterity. These factors make glucose self-monitoring particularly challenging. Minimally invasive glucose monitoring methods, particularly continuous glucose monitoring (CGM) as well as emerging non-invasive glucose monitoring technologies offer potential solutions, but remain insufficiently evaluated in older adults. Objective: To systematically review and synthesize available evidence on the advantages of continuous glucose monitoring (CGM) and non-invasive glucose monitoring methods in older adults aged ≥65 years, focusing on clinical efficacy, usability, adherence, and existing knowledge gaps. Methods: A systematic literature search was conducted across PubMed, Scopus, and Web of Science, including studies from 2020 to 2025. Eligible studies included participants aged ≥65 years and evaluated the clinical performance of CGM or other minimally invasive or non-invasive glucose monitoring technologies. The PRISMA framework guided screening and selection. Risk of bias was assessed using RoB 2 and ROBINS-I tools. Due to substantial heterogeneity among study designs and reported outcomes, a narrative synthesis approach was adopted. Results: A total of 426 records were identified, of which 13 met the predefined eligibility criteria after full-text screening. After risk of bias assessment, one study was excluded, resulting in 12 studies included in the final synthesis. No eligible studies evaluating completely non-invasive glucose monitoring technologies were identified, highlighting a significant research gap in this area specifically for older adults. CGM was associated with improved glycemic control, reduced hypoglycemia, and increased time in range among older adults. Usability was generally high, particularly with newer, user-friendly devices. Conclusions: CGM is associated with improved glycemic outcomes and favorable usability in adults aged ≥65 years. However, a significant gap exists in research on non-invasive glucose monitoring technologies in this population. Future studies should address the accuracy, feasibility, and usability of non-invasive glucose monitoring devices, while accounting for the physiological and behavioral complexities associated with aging.

The textile and clothing industry exerts a significant environmental impact in the EU, contributing heavily to water, land, and resource depletion, with waste generation expected to rise sharply due to fast fashion trends. Accelerating circularity and closed-loop production is critical to reduce the sector’s ecological footprint. This study investigates newer approaches for the removal of indigo prints from cotton (CO) and polyester (PES) textiles using aqueous-based solutions and/or ozone treatment. Aqueous alkaline solutions containing reducing agents and surfactants were evaluated, as well as dry and wet ozone treatments. The efficacy of colour removal was assessed via spectrophotometric analysis [colour strength (K/S) and colour difference (ΔE)] and the fabrics were tested for dimensional stability and tensile strength before and after treatment. Results reveal that surfactant-assisted aqueous treatments enable effective pigment removal and maintain textile properties, supporting subsequent reprinting for textile upcycling. Wet ozone treatment also promoted substantial decolourisation, particularly in cellulosic substrates. Although PES samples exhibited better mechanical resistance, they revealed limited pigment extraction upon ozone treatment. These findings demonstrate the potential of chemical treatments using aqueous-based solutions and surfactants for circular textile applications, facilitating pigment removal without compromising substrate integrity, and boosting the upcycling.

Stone heritage deteriorates through physical, chemical, and biological processes driven by water, climate, and microbial colonization. Multifunctional polymeric coatings combining hydrophobic and antimicrobial moieties have emerged as a promising conservation strategy, yet a substantial gap remains between laboratory innovation and real-world performance. This review critically examines advances from 2021 to 2026, covering wetting theory, antimicrobial mechanisms, and material architectures, including molecularly integrated systems, Sol–Gel hybrids, nanocomposites, and layered systems. Long-term studies on the Aurelian Walls in Rome and stone in Reims show that biocidal efficacy typically declines within one to two years despite the chemical persistence of the coatings. In parallel, hydrophobic performance often deteriorates over time due to UV exposure, particulate deposition, and surface chemical changes, leading to increased wettability and reduced protective efficiency. Substrate porosity governs durability and visual compatibility (ΔE* < 5 threshold), while treatments can reshape microbial communities, favoring stress-tolerant meristematic fungi. Regulatory pressure on fluorinated compounds drives the development of more sustainable alternatives. Emerging directions include stimuli-responsive systems, self-healing materials, slippery interfaces, and precision polymer architectures. However, future progress will depend on tailoring formulations to major lithotypes, improving compatibility with porous substrates, and validating performance through standardized accelerated aging and multi-year field trials. Bridging laboratory design with environmental exposure data and conservation practice will be essential for achieving durable and culturally acceptable protection strategies. Full article
