AB  - Human osteosarcoma (OS) is a relatively rare malignancy preferentially affecting long body bones which prognosis is often poor also due to the lack of effective therapies. Clinical management of this cancer basically relies on surgical removal of primary tumor coupled with radio/chemotherapy. Unfortunately, most osteosarcoma cells are resistant to conventional therapy, with the undergoing epithelial-mesenchymal transition (EMT) giving rise to gene expression reprogramming, thus increasing cancer cell invasiveness and metastatic potential. Alternative clinical approaches are thus urgently needed. In this context, the recently described ferroptotic cell death represents an attractive new strategy to efficiently kill cancer cells, since most chemoresistant and mesenchymal-shaped tumors display high susceptibility to pro-ferroptotic compounds. However, cancer cells have also evolved anti-ferroptotic strategies, which somehow sustain their survival upon ferroptosis induction. Indeed, here we show that osteosarcoma cell lines display heterogeneous sensitivity to ferroptosis execution, correlating with the mesenchymal phenotype, which is consistently affected by the expression of the well-known anti-ferroptotic factor ferroptosis suppressor protein 1 (FSP1). Interestingly, inhibiting the activity or expression of FSP1 restores cancer cell sensitivity to ferroptosis. Moreover, we also found that: i) AKRs might also contribute to resistance; ii) NRF2 enhances FSP1 expression upon ferroptosis induction; while iii) p53 contributes to the regulation of FSP1 basal expression in OS cells. In conclusion, FSP1 expression can potentially be used as a valuable predictive marker of OS sensitivity to ferroptosis and as a new potential therapeutic target.

AB  - In the present research, the two different systems of dye based on zinc phthalocyanine were prepared by microwave-induced synthesis and conventional methods. They were evaluated as new effective chemical-based dosimeters for gamma irradiation. The sensitivity of the prepared dosimeters was examined by studying the comparative results between them through the changes in structural and optical properties upon exposure to different gamma irradiation doses. The color bleaching of the solutions was followed spectrophotometrically. Gradual changes from blue to light yellow color of zinc phthalocyanine solution, with the increase of the gamma radiation dose, were observed due to the decomposition of the dyes based on the zinc phthalocyanine. The synthesized zinc phthalocyanine chemical-based dosimeters for measurement of gamma irradiation up to 25kGy showed excellent stability after irradiation in terms of morphology and structure, which makes them a suitable novel material as composite-based dosimeters of gamma irradiation.

AB  - Maple syrup, a popular natural sweetener has a high content of sucrose, whose consumption is linked to different health issues such as obesity and diabetes. Hence, within this paper, the conversion of sucrose to prebiotics (fructo-oligosaccharides, FOS) was proposed as a promising approach to obtaining a healthier, value-added product. Enzymatic conversion was optimized with respect to key experimental factors, and thereafter derived immobilized preparation of fructosyltransferase (FTase) from Pectinex® Ultra SP-L (FTase-epoxy Purolite, 255 IU/g support) was successfully utilized to produce novel functional product in ten consecutive reaction cycles. The product, obtained under optimal conditions (60 ◦C, 7.65 IU/mL, 12 h), resulted in 56.0% FOS, 16.7% sucrose, and 27.3% monosaccharides of total carbohydrates, leading to a 1.6-fold reduction in caloric content. The obtained products` prebiotic potential toward the probiotic strain Lactobacillus plantarum 299v was demonstrated. The changes in physico-chemical and sensorial characteristics were esteemed as negligible.

AB  - Providing structural information on drug-like compounds is a significant step in efforts to develop innovative drugs with balanced solubility, cell permeability and target binding. In this paper, a new cyclohexane-5-spirohydantoin tethered with a 4‑tert-butylbenzoyl group was synthesized and its crystal structure was determined using the single crystal X-ray diffraction. The Hirshfeld surface analysis was used to gain a preliminary insight into the proportion and nature of the intermolecular interactions in the crystal structure, while their quantitative description is further presented in terms of a systematic analysis of dimeric motifs representing different recognition modes. A combination of N–H∙∙∙O and C(sp3)–H∙∙∙O hydrogen bonds, C(sp3)–H∙∙∙π, lone-pair∙∙∙π and π∙∙∙π stacking interactions links the molecules into a bilayer having two carbonyl O atoms exposed to the exterior. Further stacking of the bilayers occurs through C(sp3)–H∙∙∙O hydrogen bonds involving these O atoms as acceptors, C(sp3)–H∙∙∙π and π∙∙∙π stacking interactions between the phenyl groups. The molecular electrostatic potential surface map reveals that the carbonyl O atoms of the hydantoin ring and the phenyl ring are electrophilic centers, while the N1–H1 group is a nucleophilic center. The calculated HOMO and LUMO energies were used to semiquantitatively estimate the global reactivity descriptors suggesting the soft nature of the molecule.

AB  - The implementation of the liquid organic hydrogen carrier (LOHC) technology for efficient energy storage requires the development of a reliable kinetic model for both hydrogenation and dehydrogenation processes. In this research study, the catalytic hydrocarbon saturation for a dibenzyltoluene (DBT) mixture solution, containing dibenzylbenzene (DBB), dibenzylethylbenzene (DBEB) and impurities has been performed in the presence of Ru/Al2O3 particles. The influence of different reaction conditions, such as temperature, pressure, initial reactant concentration, catalyst amount and stirring speed has been examined. A measurement-based system micro-kinetics, based on the Langmuir–Hinshelwood mechanism with dissociative H2 surface adsorption, has been derived. H2 thermodynamic solubility equilibrium was defined through Henry's law. The adsorbing, desorption and reactivity of inert solvent molecules was not considered to be relevant. The mass transfer resistance over 1000 rpm stirring speed was negligible. Relative- and mean squared error of representation were 40.9% and 1.00×10−4, respectively. Expressions gave an excellent data prediction for the profile period trends with a relatively accurate estimation of H2 intermediates' rate selectivity, H2-covered area approximation and pathway rate-determining steps. Due to the lack of commercially available standard chemical compounds for quantitative analysis techniques, a novel experiment-based numerical calibration method was developed. Mean field (micro)kinetics represent an advancement in the mesoscale mechanistic understanding of physical interface phenomena. This also enables catalysis structure–activity relationships, unlocking the methodology for new LOHC reaching beyond traditional, such as ammonia, methanol and formate, which do not release H2 alone. Integrated multiscale simulations could include fluidics later on.

AB  - Environmentally benign pH-indicating wound dressing comprised of carbohydrates chitosan (CH) and pectin (P), and anthocyanin grape (AG) dye is created via layer-by-layer assembly. Cotton fabric coated with eight bilayers of (CH-AG)4/(P-AG)4 deposited 1.97 % AG-dye. It exhibited a visible and immediate color change from pink to violet-blue while increasing its pH value from 6 to pH 7, matching the turning pH point of healing into an infected wound. Color transition of AG-dye in water-based buffers, tested by VIS-spectroscopy, shows the same color change when the pH value increased from 6 to 7. This coating imparts excellent antimicrobial activity against Gram-positive bacteria Staphylococcus aureus and yeast Candida albicans, moderate antibacterial activity against Gram-negative Escherichia coli bacteria, and no cytotoxicity on human fibroblast cells (MRC-5). This research proposes a sustainable, low-cost, and simple method for obtaining smart wound dressing that provides real-time monitoring of the wound pH.

AB  - Three novel triphenyltin(IV) compounds with modulated azo-carboxylato ligands: triphenylstannyl (E)-4-((2-hydroxynaphthalen-1-yl)diazenyl)benzoate, 1, triphenylstannyl (E)-4-((4-hydroxyphenyl)diazenyl)benzoate, 2, and triphenylstannyl (E)-4-((4-(dimethylamino)phenyl)diazenyl)benzoate, 3, were synthesized and characterized by elemental analysis, FTIR and NMR (1H, 13C, 119Sn) spectroscopy. The structures and spectra of compounds were predicted by Density Functional Theory (DFT) methods at B3LYP-D3BJ/6–311++G(d,p)(H,C,N,O)/LanL2DZ(Sn) level of theory. Furthermore, the antitumor potential of ligand precursors, HL1–HL3, and appropriate organotin(IV) compounds 1–3 was evaluated across mouse melanoma B16F1, human breast adenocarcinoma MCF-7, human colorectal HT-29 and human prostate PC3 cell lines using MTT and CV assays. The organotin(IV) compounds exhibit enhanced cellular uptake and efficacy in reducing viable cell numbers when compared to free acids. Specifically, compound 3 demonstrates a notable impact at lower nanomolar concentrations on all tested cell lines. Moreover, 3 induces cell death in MCF-7 cells by inhibiting cell division and promoting the overproduction of cellular nitric oxide (NO), ultimately leading to caspase-independent apoptosis. Importantly, this process occurs without concurrent activation of autophagy or the generation of ROS/RNS species. The binding affinity of 1–3 with calf thymus DNA (CT-DNA) and bovine serum albumin (BSA) was investigated by fluorescence spectroscopy and molecular docking simulations, suggesting their capacity to interact with these biomolecules.

AB  - Objectives: To assess and compare the cell viability and ion release profiles of two conventional glass ionomer cements (GICs), Fuji IX and Ketac Molar EasyMix, modified with TiO2 and Mg-doped-HAp nanoparticles (NPs). Methods: TiO2 NPs, synthesized via a sol–gel method, and Mg-doped hydroxyapatite, synthesized via a hydrothermal process, were incorporated into GICs at a concentration of 5 wt.%. The biocompatibility of prepared materials was assessed by evaluating their effects on the viability of dental pulp stem cells (DPSCs), together with monitoring ion release profiles. Statistical analysis was performed using One-way analysis of variance, with significance level p < 0.05. Results: The addition of NPs did not significantly affect the biocompatibility of GICs, as evidenced by comparable decreased levels in cell viability to their original formulations. Distinct variations in cell viability were observed among Fuji IX and Ketac Molar, including their respective modifications. FUJI IX and its modification with TiO2 exhibited moderate decrease in cell viability, while other groups exhibited severe negative effects. While slight differences in ion release profiles were observed among the groups, significant variations compared to original cements were not achieved. Fluoride release exhibited an initial “burst release” within the initial 24 h in all samples, stabilizing over subsequent days. Conclusions: The addition of NPs did not compromise biocompatibility, nor anticariogenic potential of tested GICs. However, observed differences among FUJI IX and Ketac Molar, including their respective modifications, as well as induced low viability of DPSC by all tested groups, suggest the need for careful consideration of cement composition in their biological assessments. Clinical significance: The findings contribute to understanding the complex interaction between NPs and GIC matrices. However, the results should be interpreted recognizing the inherent limitations associated with in vitro studies. Further research avenues could explore long-term effects, in vivo performance, and potential clinical applications.

AB  - Energy systems are undergoing rapid change as the world responds to climate change. Many policymakers may ask, what will be the next great energy source for a low-carbon future? All indications so far point to hydrogen energy. Although it is anticipated that costs will likely fall as the hydrogen production scale increases, it may be reported that the high technology costs remain a barrier to the widespread shift towards hydrogen. This paper presents hydrogen production costs for various production methods for different regions across the world, including the USA, the Middle East, Europe, India, and Canada. The costs of hydrogen production from biomass gasification, coal gasification, and natural gas reforming are compared, revealing the varying costs across different regions. Moreover, the production of green hydrogen from renewable energy sources is also presented, and compared with conventional methods. It highlights that while green hydrogen is environmentally sustainable, its production remains cost-intensive compared to integrated processes. Notably, the Middle East and India demonstrate the most economical production costs for both electrolysis and nuclear-based processes, while Europe shows the highest costs. The information presented in this paper could be helpful for researchers and policymakers to make informed decisions regarding the necessary aspects that still need to be investigated, to help with the transition into a hydrogen energy future.

AB  - Nanoparticles  prepared by heat treatment of protein from pumpkin leaves were evaluated as potential carriers of β-carotene. White protein fraction was recovered from green juice produced by pressing the leaves, with the step of enzyme-assisted extraction (green protocol) or without it (conventional protocol). Heat treatment of white protein fractions from conventional and green protocols at 90 °C and pH 9.3 during 20 min induced formation of nanoparticles with peak diameter 18 nm and 21 nm, respectively. Due to heating, portion of β-sheets in nanoparticles from both native protein fractions decreased by approximately 15 %, associated with an increase in surface hydrophobicity-to-area ratio. Quenching constant of β-carotene for nanoparticles was increased nearly 100 times by heating the white protein fraction recovered in green protocol. Native white protein fraction from conventional protocol and corresponding nanoparticles exhibited high ability to bind β-carotene, with quenching constant 3 × 105 L/mol and 3.3 × 105 L/mol, respectively. White protein fraction from pumpkin leaves appeared to be a suitable substrate for the fabrication of nanoparticles by heat treatment, with potential application as β-carotene nanocarriers in food matrices.

AB  - Failure analysis of welded joint with multiple defects was performed taking into account the effect of all defects, not just a dominant one. Four cases of multiple defects in welded joint under the uniaxial tensile loading were investigated using extended Finite Element Method. Two-dimensional Finite Element Models were made according to the tensile specimens with initial crack located in a critical area of welded joint. For each multiple defects case, numerical simulation was performed with three initial crack depth. Engineering Critical Analysis was made using Failure Assessment Diagrams for each defect that was determined as critical for its welded joint case. Numerical simulation showed that the geometry of the most prominent one from a point of view of structural integrity. It was concluded that the vertical misalignment in combination with a secondary defect, had the most adverse effect which can lead to failure of welded structure.

AB  - Pesticides used in coffee cultivation may remain behind and pose a risk to humans even after various processing stages of coffee beans (washing, drying, roasting, and grinding). In addition to pesticides applied to battle pests and diseases, mepiquat formation occurs during roasting. A comprehensive LC-MS/MS and GC-MS/MS multi-residue screening approach to determine pesticides in coffee was used in this study. Residues were extracted using the QuEChERS method and analyzed using multiple reaction monitoring (MRM) mass spectrometry after chromatographic separations. Good linearity (r2˃0.9919), recovery (80.2–118%), and RSD (≤19%) were obtained for the procedure including sample preparation and both instrumental techniques. Nine residues were identified as commonly present in coffee samples collected from supermarkets in Serbia. The human intake risk of pesticides was categorized and prioritized using the matrix ranking scheme. Also, health risk assessment was conducted by calculating acute and chronic hazard indices. Multi-residues were present in 79.2% of samples, whereas mepiquat chloride (88.9%) and permethrin (81.9%) were the most detected residues. Risk ranking classified mepiquat chloride, permethrin, and methiocarb sulfone in a high-risk group. On the other hand, the human health risk assessment indicated no risks in the short- and long-term and no cumulative chronic risk.

abstract = "Pesticides used in coffee cultivation may remain behind and pose a risk to humans even after various processing stages of coffee beans (washing, drying, roasting, and grinding). In addition to pesticides applied to battle pests and diseases, mepiquat formation occurs during roasting. A comprehensive LC-MS/MS and GC-MS/MS multi-residue screening approach to determine pesticides in coffee was used in this study. Residues were extracted using the QuEChERS method and analyzed using multiple reaction monitoring (MRM) mass spectrometry after chromatographic separations.

AB  - This study focuses on the development of bioactive materials using environmentally friendly techniques, renewable, biocompatible, and biodegradable polysaccharide, as well as natural bioactive compounds (NBCs) found in plant extracts. First, cornstarch aerogels with a porosity of 86 % and a specific surface area of 225 m2/g were produced via supercritical CO2- assisted drying. Further, thymol, citronellol, carvacrol, and eugenol were incorporated into the aerogels by supercritical CO2- assisted impregnation, which allowed variation in loadings of NBCs (12.8–17.6 %). Interaction between cornstarch aerogels and NBCs determined impregnation rate, pore wall thickness (in the range 18–95 nm), liquid absorption capacity (from 265 to 569 %), dehydration mass loss, and release in phosphate-buffered saline. Controlled release of NBCs was maintained over a 3-day period. Moreover, impregnated aerogels showed a significant antioxidant effect with the highest value for DPPH radical inhibition of 25.5 % determined for the aerogels impregnated with eugenol. Notable antimicrobial activity against tested Gram-negative bacteria, Gram-positive bacteria, and fungi was also observed, being the highest for thymol-loaded aerogel with the diameter of the inhibition zones of up to 37.5 mm. This work shows a promising green approach for the production of bioactive two-component starch-based materials for potential applications in skin infection treatment.

AB  - Polymer composites based on unsaturated polyester resin (UPR) and reinforced with particles based on unmodified/modifiedplant provenance biosilica particles were synthesized and characterized. An unsaturated polyester resin was obtained fromwaste poly (ethylene terephthalate (PET). Biosilaca particles are made from rice husk biomass. The surface of the producedsilica particles was modified using three different silanes: 3-trimethoxysilylpropyl methacrylate (MEMO), trimethoxyvinylsilane (TMEVS), and 3-aminopropyltrimethoxysilane (APTMS). The microhardness test method was used to investigatethe mechanical properties of synthesized composite material with variations in dwell times and applied loads. Optimization ofcomposite microhardness value prediction in function of synthesized parameters (type of modification of silica particles) andmeasurement parameters (applied loads and dwell times) was done using the method of response surface methodology (RSM)regression analysis. The maximal microhardness values (0.459 GPa) were obtained of type modification of silica particles withvinyl with 80% confidence for 120 experimental variables. This method can be used to choose the optimal dwell time and loadfor comparison of measurements between different composite materials and to enable the choice of the material in terms ofoptimization of the quality of reinforcement and quality of interphase determined by surface modification.

AB  - This study aimed to investigate the adsorption of As(V), phosphate, and textile dye Acid Green 25 (AG-25) on layered double hydroxides Mn-Fe_LDH and corresponding membranes (wCell/Mn-Fe_LDH). The wCell membrane, derived from waste tobacco boxes, was formed by cross-linking of epoxy and amino modified cellulose fibers with epoxy modified Mn-Fe_LDH and lysine as cross-linker. Structural and morphological analyses were conducted for Mn-Fe_LDH and wCell/Mn-Fe_LDH. The batch system explored pH, contact time, temperature, and initial concentration effects on wCell/Mn-Fe_LDH adsorption efficiency. Adsorption capacities of 82.71, 106.9, and 130.3 mg g−1 were achieved for As(V), phosphate, and AG-25, respectively, indicating effective anionic species removal. Kinetic analysis suggested intraparticle diffusion as the rate-limiting step. Thermodynamic parameters and ionic strength effects indicated a physisorption mechanism for AG-25 and surface complexation for As(V) and phosphate. Biodegradation experiments after five adsorption/desorption cycles revealed the membrane’s decomposition, with phosphate’s strong bonding releasing essential elements valuable for soil fertilization. Effluent wastewater treatment demonstrated low environmental impact through the formation of insoluble As(V) salts and photocatalytic dye degradation.

AB  - The increase in waste polymer recycling has helped in promoting sustainability, and together with the use of renewable raw materials, it has become a widespread concept with positive effects on both the economy and ecology. Accordingly, the aim of this study was the synthesis of “green” plasticizers, marked as LA/PG/PET/EG/LA, formed from waste poly(ethylene terephthalate) (PET) and bio-based platform chemicals propylene glycol (PG) and levulinic acid (LA). The structure of the obtained plasticizers was complex, as confirmed by results from nuclear magnetic resonance (NMR) and Fourier-transform infrared spectroscopy (FTIR) analysis. The LA/PG/PET/EG/LA plasticizers and waste poly(vinyl chloride) (PVC) were used in an optimized technology for PVC re-granulate production. The hardness of the PVC-based material with “green” plasticizers, in comparison to commercial plasticizer dioctyl terephthalate (DOTP), increased by 11.3%, while migration decreased. An improved material homogeneity and wettability of the fibers by the matrix were observed using SEM analysis of the material’s fracture surface, with a higher efficiency of intermolecular interactions leading to better mechanical performances of the newly designed materials. Thus, LA/PG/PET/EG/LA are unique materials with good compounding and plasticizing potential for PVC, as revealed by differential scanning calorimetry (DSC) and dynamic mechanical analysis (DMA). In that manner, the use of bio-renewable resources and recycled polymers will contribute to diminishing waste polymer generation, contributing to a lower carbon footprint.

AB  - Vaccinium myrtillus L. leaves contain bioactive components, such as polyphenols, stilbenes, iridoid glycosides, fatty acids, and fibers. However, polyphenols possess low solubility, stability, and bioavailability, thus the encapsulation of the mentioned active principles in different carriers is necessary. Liposomes are widely used as a carrier for the encapsulation, preservation, and controlled release of polyphenols in various products. Therefore, the aims of the presented research are the development and characterization of V. myrillus leaf extract-loaded liposomes via the determination of encapsulation efficiency, particle size, polydispersity index (PDI), zeta potential, and mobility.

AB  - Without being aware of their chemical composition, many cultures have used herbaceous peony roots for medicinal purposes. Modern phytopreparations intended for use in human therapy require specific knowledge about the chemistry of peony roots and their biological activities. In this study, ethanol–water extracts were prepared by maceration and microwave- and ultrasound-assisted extractions (MAE and UAE, respectively) in order to obtain bioactive molecules from the roots of Paeonia tenuifolia L., Paeonia peregrina Mill., and Paeonia officinalis L. wild growing in Serbia. Chemical characterization; polyphenol and flavonoid content; antioxidant, multianti-enzymatic, and antibacterial activities of extracts; and in vitro gastrointestinal digestion (GID) of hot water extracts were performed. The strongest anti-cholinesterase activity was observed in PT extracts. The highest anti-ABTS (2,2′-azino-bis(3-ethylbenzothiazoline-6-sulphonic acid) radical potential was observed in PP extracts, whereas against DPPH (2,2-diphenyl-1-picrylhydrazyl radicals), the best results were achieved with PO extracts. Regarding antibacterial activity, extracts were strongly potent against Bacillus cereus. A molecular docking simulation was conducted to gather insights into the binding affinity and interactions of polyphenols and other Paeonia-specific molecules in the active sites of tested enzymes. In vitro GID of Paeonia teas showed a different recovery and behavior of the individual bioactives, with an increased recovery of methyl gallate and digallate and a decreased recovery of paeoniflorin and its derivatives. PT (Gulenovci) and PP (Pirot) extracts obtained by UAE and M were more efficient in the majority of the bioactivity assays. This study represents an initial step toward the possible application of Paeonia root extracts in pharmacy, medicine, and food technologies.

AB  - The surfaces of natural (NZ) and zeolite/iron oxyhydroxide composite (ZFe) samples were analysed by means of inverse gas chromatography (IGC) using the adsorption data of organic non-polar and polar probes, in the infinite and finite-dilution regimes, in the temperature range 483-513 K. The dispersive components of the free energy of adsorption, γS, determined by the Gray method, decreased with increasing temperature for both zeolites. The specific interactions were characterised by the specific free adsorption energy change, ΔGaS, the specific enthalpy change of adsorption, ΔHaS, as well as the donor and acceptor interaction parameters (KA, KD) and the basic character of the NZ and ZFe was evidenced. The adsorption isotherms of n-hexane, benzene, chloroform and tetrahydrofuran (THF) were determined under finite surface coverage and used to estimate the specific surface area and the adsorption energy distribution. The adsorption capacity of the ZFe was higher than for NZ for all the investigated adsorbates. The specific surface areas and pore size distributions were also determined using nitrogen adsorption-desorption isotherms, i.e., the BET method. It was observed that the nature of the adsorbate and the properties of the solid surface of the initial and modified samples governed the uptake of adsorbates.

Капацитет адсорпције узорка ZFe је био већи у односу на капацитета узорка NZ, за све испитане адсорбенте.

AB  - This study aimed to (1) comparatively analyze properties of Sr- and Mg-substituted
hydroxyapatite (HAP)-based dental inserts; (2) evaluate insert bonding to restorative
materials, and (3) evaluate the effect of doped HAP inserts on fracture resistance
(FR) of human molars with large occlusal restorations. By ion-doping with Sr or Mg,
3 insert types were obtained and characterized using XRD, SEM, Vickers hardness and
fracture toughness. Shear bond strength (SBS) was determined between acid etched or
unetched inserts and following materials: Maxcem cement (Kerr); Filtek Z250
(3M) bonded with Single Bond Universal (SBU; 3M) or Clearfil Universal (Cf; Kuraray).
Modified Class I cavities were prepared in 16 intact molars and restored using insert
+ composite or composite only (control) (n = 8/group). FR of restored molars was
determined by static load until fracture upon thermal cycling. Fracture toughness was
similar between Sr/Mg-doped inserts (0.94–1.04 MPam 1/2 p = .429). Mg-doped
inserts showed greater hardness (range 4.78–5.15 GPa) than Sr6 inserts (3.74
± 0.31 GPa; p < .05). SBS for SBU and Cf adhesives (range 7.19–15.93 MPa) was higher
than for Maxcem (range 3.07–5.95 MPa) (p < .05). There was no significant difference
in FR between molars restored with insert-containing and control restorations (3.00
± 0.30 kN and 3.22 ± 0.42 kN, respectively; p > .05). HAP-based inserts doped with
Mg/Sr had different composition and mechanical properties. Adhesive bonding to
inserts resulted in greater bond strength than cementation, which may be improved by
insert acid-etching. Ion-doped HAP inserts did not affect FR of restored molars. In conclusion,
HAP-based dental inserts may potentially replace dentin in large cavities, without
affecting fracture resistance of restored teeth.

in FR between molars restored with insert-containing and control restorations (3.00
± 0.30 kN and 3.22 ± 0.42 kN, respectively; p > .05). HAP-based inserts doped with
Mg/Sr had different composition and mechanical properties. Adhesive bonding to
inserts resulted in greater bond strength than cementation, which may be improved by
insert acid-etching. Ion-doped HAP inserts did not affect FR of restored molars. In conclusion,
HAP-based dental inserts may potentially replace dentin in large cavities, without
affecting fracture resistance of restored teeth.",
