It is known that plant-associated microorganisms must be considered as key drivers for plant health, productivity, community composition, and ecosystem functioning. Much attention has been paid to the exploration of the plant-associated microbiome in search of new microorganisms with antagonistic activity against various phytopathogens. P. viticola represents one of the main fungal agents of grape yield losses during the pre-harvest stage. To date, the use of chemical pesticides is the main method to control downy mildew infection in vineyards. In recent years, innovative and more environmentally suitable control strategies, such as Biological Control Agents (BCAs), have been greatly improved. In this study, 16 new bacterial strains, isolated from the leaves of three table grape cultivars, were tested for their in vivo effectiveness against downy mildew of grape, resulting in one B. velenzensis (‘BLG_B4), one P. pleuroti (‘BLG_B5), one P. psychrotolerans (‘BLG_B1.3’) and one B. subtilis (‘BLG_B1.1.1’) bacterial strains that were marked as good BCAs. As possible mechanisms of action, a genetic analysis was performed to evaluate the ability of selected bacterial strains to reduce the expression of two P. viticola effectors. Finally, their effectiveness against a wide range of fungal pathogens and their safety for human health was also evaluated. Full article

Exposure to ultraviolet (UV) radiation is a major contributor to skin injury, including sunburn, photoaging, and augmented risk of skin cancer, primarily through the generation of reactive oxygen species (ROS) that induce oxidative stress. Rosmarinic acid (RA), a natural phenolic compound with antioxidant and several other biological properties, has shown promise in mitigating such damage when incorporated into sunscreens. We evaluated RA’s possible interactions and potential to enhance the efficacy of three worldwide known UVB filters—ethylhexyl methoxycinnamate (EHMC), octocrylene (OCT), and ethylhexyl salicylate (EHS). The performance of sunscreens with and without RA (0.1% w/w) was analyzed through in vitro and in vivo photoprotective assessments. The HPLC-TBARS-EVSC (high-performance liquid chromatography—thiobarbituric acid reactive substances—ex vivo stratum corneum) protocol, which quantified oxidative stress reduction in the human stratum corneum, was also used. The in vitro photoprotective assays showed that RA had distinct levels of interactions with the UVB filters. When associated with EHMC, RA exclusively acted in the UVB range (SPF-enhancing effect). Remarkably, for EHS, RA contributed to a higher efficacy profile in the total UV spectrum. OCT-RA was the sample that reached the highest critical wavelength value parallelly to OCT, boosting the in vivo SPF by more than 157% in comparison to OCT. However, its in vitro SPF performance was not affected by the RA addition, being comparable to OCT, EHS, and EHS-RA. Furthermore, the HPLC-TBARS-EVSC protocol highlighted RA’s ability to reduce lipid peroxidation, with OCT-RA exhibiting the most notable protective effect. These findings underscore RA’s potential as a multifunctional additive in sunscreen systems, enhancing both photoprotection and oxidative stress mitigation. Full article

Parkinson’s disease (PD) represents a growing challenge to global health, as it involves millions of people. The high grade of disability is due to the loss of dopaminergic neuron activity, and levodopa is the gold-standard therapy used to restore dopamine in the dopamine-denervated regions. Another therapeutic approach is the use of A_2A adenosine receptor antagonists and, among them, istradefylline is the only one currently approved for therapy in association with levodopa. In this work, we synthesized A_2A adenosine receptor antagonists represented by 9-ethyl-2,8-disubstituted adenine derivatives, which were tested at human adenosine receptors in binding and functional assays. These compounds showed A_2A adenosine receptor-binding affinities in the low nanomolar range and 1, 4, and 5 exhibited good potency in the functional assays. Hence, they were evaluated in in vivo rat models of PD, where they were demonstrated to revert haloperidol-induced catalepsy and potentiate levodopa-induced contralateral rotations in 6-hydroxydopamine-lesioned rats. The most potent derivative, 4, was then evaluated in the tacrine model, where it reduced the tremulous jaw movements, therefore demonstrating an action on parkinsonian tremor. These data revealed 8-ethoxy-2-phenethoxy-9-ethyladenine (4) as an A_2A adenosine receptor antagonist endowed with antiparkinsonian effects and as a good candidate to treat the disease. Full article

Dysregulated iron metabolism-induced ferroptosis is considered a key pathological mechanism in the development of osteoporosis (OP). G protein-coupled receptor 30 (GPR30, also known as Gper1) is an estrogen-binding receptor that has shown therapeutic benefits in patients with certain degenerative diseases. Moreover, several studies have demonstrated the anti-ferroptotic effects of estrogen receptor activation. However, its role in the prevention and treatment of OP remains unclear, and there are currently no reports on the anti-ferroptotic function of GPR30 in OP. Therefore, this study aimed to investigate the ferroptosis-related effects and mechanisms of GPR30 in the context of OP. In vivo and in vitro experiments were conducted using wild-type (WT) C57BL/6 female mice and GPR30-knockout (GPR30-KO) C57BL/6J female mice. The microarchitecture of the distal femur was assessed using micro-computed tomography (micro-CT), and histomorphological changes were analyzed via hematoxylin and eosin (H&E) staining. Bone marrow mesenchymal stem cells (BMSCs) were isolated and cultured to establish an iron overload model using ferric ammonium citrate (FAC). Interventions included GPR30 overexpression via transfection and BMP-6 inhibition using LDN-214117. Cell viability was evaluated with the CCK-8 assay, while osteogenic differentiation and mineralization levels were assessed using ALP and Alizarin Red S (ARS) staining. Iron accumulation was detected via Prussian blue staining, oxidative stress levels were evaluated using ROS staining, and mitochondrial membrane potential changes were analyzed using JC-1 staining. Transmission electron microscopy (TEM) was employed to observe mitochondrial ultrastructural changes. Additionally, key gene and protein expression levels were measured using immunofluorescence and Western blotting. The micro-CT analysis revealed significant bone microarchitecture deterioration and bone loss in the GPR30-KO mouse model. At the cellular level, GPR30 overexpression markedly reduced iron accumulation and oxidative stress in BMSCs, restored the mitochondrial membrane potential, and improved the mitochondrial ultrastructure. Furthermore, GPR30 enhanced osteogenic differentiation in BMSCs by promoting the activation of the BMP-6/HEP/FPN signaling pathway, leading to increased expression of osteogenic markers. The protective effects of GPR30 were reversed by the BMP-6 inhibitor LDN-214117, indicating that BMP-6 is a critical mediator in GPR30-regulated iron metabolism and ferroptosis inhibition. GPR30 inhibits ferroptosis in BMSCs and enhances osteogenic differentiation by activating the BMP-6/HEP/FPN signaling pathway. This provides new insights and potential therapeutic targets for the treatment of osteoporosis OP. Full article

Hypericum perforatum L. (H.P.) is a species with a well-documented history of use in wound healing practices across the globe. The objective of this study was twofold: firstly, to evaluate the in vivo efficacy of liposomal in situ gel formulations in wound healing, both clinically and histopathologically, and secondly, to determine the physicochemical characterization of liposomal in situ gel formulations. The in vitro studies will be assessed in terms of particle size, zeta potential, release kinetics, rheological behaviors, and antioxidant and antimicrobial properties. The in vivo studies will be evaluated in clinical animal experiments and pathology studies. The in-situ hydrogel formulations were prepared using the physical cross-linking method with Poloxamer 188, Poloxamer 407, Ultrez 21, and Ultrez 30. The liposome formulations phospholipid 90H and lipoid S100 were prepared using the thin film solvent evaporation method. The antioxidant activity of the samples was evaluated through in vitro studies employing the DPPH antioxidant activity, ABTS+ test, and FRAP test. The antimicrobial activity of the samples was evaluated through the determination of MIC and MBC values employing the 96-well plate method. In vivo, 36 male New Zealand rabbits aged 32–36 weeks were utilized, with six rabbits in each group. The groups were composed of six distinct groups, including conventional and in situ gel liposome formulations of HHPM, three different commercial preparations, and a control group (n = 6). The HHPM-LG8 formulation developed in this study was found to be applicable in terms of all its properties. The new liposomal in situ hydrogel formulation demonstrated notable wound healing activity, a result that was supported by the formulation itself. Full article

Increasing cases of sunburn is one of the serious problems across the globe. In this connection, there is an urgent requirement for some effective sun screening agents. In the search for the same, nanoemulsions of some new synthesized and characterized chalcone derivatives were prepared and evaluated in vitro and in vivo. In order to meet the said objective, in the first step, vanillin was reacted with 4-aminoacetophenone in the presence of 15% sodium hydroxide and ethanol to synthesize the target compounds (C-1 to C-5). Progress of reaction was monitored using thin-layer chromatography (TLC). The crystals of purified compounds were characterized using spectroscopic techniques such as Infrared (IR) spectroscopy, ¹H-NMR spectroscopy, ¹³C-NMR, and mass spectrometry. We prepared the nanoemulsions of the final compounds (C-1 to C-5) and subsequently evaluated them for in vitro sun protection factor activity. The concentration of the nanoemulsions, consistently ranging from 0.88 to 0.91 mg/mL across all formulations, demonstrated a high degree of consistency. The range of particle size varied from approximately 172 to 183 nm, with low polydispersity index values (approximately 0.11 to 0.15). The negative zeta potentials recorded for all the formulations (ranging from −35.87 mV to −39.30 mV) showed that the nanoemulsions are electrostatically stable enough to keep them from sticking together. The pH values of the nanoemulsions ranged narrowly from approximately 5.00 to 5.16, which indicated the compatibility of emulsion with biological systems and the potential to reduce irritation or instability during administration. The viscosity of the nanoemulsions varied between 2.00 and 2.12 cP. In silico studies were performed using MMP-I and MMP-2 as target receptors. For in vitro SPF evaluation, the Mansur equation was employed. COLIPA guidelines were compiled for in vivo SPF evaluation. The nanoemulsions derived from compounds C-3 and C-4, designated as C-3 NE and C-4 NE, were more effective as anti-aging agents. Findings suggested the possible scope of further synthesis of newer synthetic derivatives of chalcones for furfur development nanoemulsions for better SPF activity. Full article

Background Despite many studies on polymer-incorporated nanocarriers for ophthalmic drug delivery, few have thoroughly explored the relationship between coating composition and performance. This study aimed to evaluate the effects of three commonly used cationic polymers—distearoyl phosphatidylethanolamine-polyethylene glycol 1000-poly(amidoamine) (DSPE-PEG1000-PAMAM), trimethyl chitosan (TMC), and (2,3-dioleoyloxypropyl) trimethylammonium chloride (DOTAP)—on the corneal behaviors and anti-cataract efficacy of diosmetin (DIO)-loaded micelles (D-M-P, D-M-T, and D-M-D, respectively). Methods The DIO-loaded micelles were prepared using the thin-film dispersion method and incorporated with the three polymers through hydrophobic interactions and electrostatic adsorption. Structural characterization was demonstrated by TEM imaging and particle size analyzer. In vitro release behavior was detected by the dialysis method. Cell viability of D-M-P, D-M-T, and D-M-D on L929 cells was detected by CCK-8 assays, with cellular uptake performed using coumarin 6 as the fluorescence indicator. Precorneal retention behaviors of these three vesicles were observed by In Vivo Imaging System. Transcorneal permeability was determined by modified Franz diffusion method and the permeation routes of the vesicles are investigated. Selenite-induced cataract model was established. The anti-cataract effects of three different DIO-loaded micelles were evaluated by the observation of lens opacity and antioxidant enzyme activities. Eye Irritation of the DIO in different preparations was estimated using the Draize test, along with H&E staining of the corneas. Results Structural characterization of DIO-loaded micelles revealed that the vesicles were spherical, with a uniform size distribution of around 28 nm, a similar surface potential of approximately 6.0 mV, and a high DIO entrapment efficiency of about 95%. Compared to the DIO suspension, all three formulations exhibited a significant sustained-release effect. They showed no signs of irritation and demonstrated increased IC50 values in L929 cells, indicating improved biocompatibility. Cellular uptake in human lens epithelial cells (HLECs) was assessed using confocal laser scanning microscopy. C-M-T displayed the highest fluorescence signals, with a cellular internalization 3.2 times greater than that of the solution group. Both C-M-T and C-M-P enhanced vesicle retention on the corneal surface by at least 47.8% compared to the Cou-6 solution. Furthermore, TMC facilitated the paracellular transport of vesicles into the deepest layers of the cornea and delivered DIO across the cornea, with a P_app value 3.11 times and 1.49 times those of D-M-D and D-M-P, respectively. In terms of therapeutic efficacy, D-M-T demonstrated the most significant attenuation of lens opacity, along with enhanced antioxidant enzyme activities and inhibition of lipid peroxidation. Conclusion The modification of micelle vesicles with different cationic polymers significantly influences their performance in ocular drug delivery. Among the tested formulations, D-M-T stands out due to its multiple advantages, including enhanced transcorneal drug delivery, therapeutic efficacy for DIO, and safety, making it the most promising candidate for ophthalmic applications.

The molecular mechanisms through which endometriosis-related ovarian neoplasms (ERONs) develop from benign endometrioma remain unclear. It is especially a long-standing mystery why ovarian endometrioma has the potential to develop into two representative histological subtypes: endometrioid ovarian carcinoma or clear cell ovarian carcinoma. This study aimed to investigate the molecular carcinogenesis of ERONs using newly developed in vitro and in vivo carcinogenesis models. Epithelial cells were isolated and purified from surgically removed benign endometrioma samples, followed by immortalization by overexpressing cyclinD1/CDK4 in combination with the human TERT gene. Immortalized cells were subjected to various molecular manipulations by combining knockout or overexpression of several candidate drivers, including ARID1A, KRAS, PIK3CA, AKT, and MYC, based on previous comprehensive genome-wide studies of ERONs. These cells were then inoculated into immunocompromised mice and evaluated for malignant transformation. Inoculated cells harboring a combination of three genetic alterations successfully developed tumors with malignant features in mice, whereas those with two genetic manipulations failed to do so. Especially, ARID1A gene knockout, combined with overexpressing the KRAS oncogenic mutant allele (or overexpressing AKT) and c-Myc overexpression led to efficient tumor formation. Of note, these three combinations of genetic alterations produced tumors that histologically represented typical clear cell carcinoma in SCID mice, while the same combination led to tumors with endometrioid histology in nude mice. A combination of ARID1A mutation, KRAS mutation or AKT activation, and c-Myc overexpression were confirmed to be the main candidate drivers for the development of ERONs, as suggested by comprehensive genetic analyses of ERONs. A tumor immune microenvironment involving B-cell signaling may contribute to the diverse histological phenotypes. The present model may help to clarify the molecular mechanisms of ERON carcinogenesis and understand their histological diversity and novel molecular targets. Full article

(1) Background: Hepatic lipid accumulation is the initial factor in metabolic-associated fatty liver disease (MAFLD) in type 2 diabetics, leading to accelerated liver damage. The NOD-like receptor protein 3 (NLRP3) inflammasome plays a critical role in this process. Dapansutrile (DAPA) is a novel NLRP3 inflammasome inhibitor; however, its effect on ectopic lipid accumulation in the liver remains unclear. This study aimed to investigate the therapeutic effect of DAPA on hepatic lipid accumulation in a diabetic mouse model and its potential mechanisms. (2) Methods: The effects of DAPA on hepatic ectopic lipid deposition and liver function under metabolic stress were evaluated in vivo using db/db and high-fat diet (HFD) + streptozotocin (STZ) mouse models. Additionally, the role and mechanism of DAPA in cellular lipid deposition, mitochondrial oxidative stress, and inflammation were assessed in HepG2 cells treated with free fatty acids (FFA) and DAPA. (3) Results: Our findings indicated that DAPA treatment improved glucose and lipid metabolism in diabetic mice, particularly addressing liver heterotopic lipid deposition and insulin resistance. DAPA treatment also ameliorated lipid accumulation and mitochondrial-related functions and inflammation in HepG2 cells through the NLRP3-Caspase-1 signaling axis. (4) Conclusions: Targeting NLRP3 with DAPA may represent a novel therapeutic approach for diabetes-related fatty liver diseases. Full article

Background/Objectives: Acinetobacter baumannii is an opportunistic nosocomial pathogen characterized by its multidrug-resistant (MDR) phenotype, increasing patient mortality and healthcare costs as a result. Previously, we constructed an immunoinformatics-based Acinetobacter Multi-Epitope Vaccine (AMEV2) candidate and demonstrated robust protection against this MDR pathogen. In this study, we delineate the mechanisms of AMEV2-mediated protective immunity. Methods: In vivo passive immunization with AMEV2 antisera and in vitro opsonophagocytic killing assays (OPKAs) were used to assess the critical role of antibody-mediated protection induced by AMEV2 vaccination. Results: The passive transfer of AMEV2 immune sera to naïve mice afforded 67% protection in a pulmonary challenge mouse model. Although AMEV2 sera reacts with bacterial antigens, it is not bactericidal on its own and does not enhance the complement-mediated direct killing of A. baumannii. However, OPKAs demonstrate AMEV2 sera enhancement of the killing of A. baumannii in the presence of primary bone marrow-derived macrophages. This killing occurs via complement and Fc gamma receptor-mediated phagocytosis. A highly immunogenic AMEV2 component peptide, pTonB, elicits pTonB-specific antibodies and protection in vivo. The depletion of pTonB antibodies from AMEV2 immune sera by pTonB absorption significantly reduced the opsonophagocytic killing of A. baumannii in vitro. Conclusions: The data presented here demonstrate the importance of humoral immunity and its protective mechanisms against A. baumannii. These findings further expand the in vivo evaluation of in silico-designed vaccines as a viable alternative to combat the current global MDR pathogen health crisis. Full article

Background/Objective: This study provided a comparison of the influence of each component of the microemulsion formulation and investigated the impact of varying concentrations of the microemulsion components on curcumin’s ability to penetrate the skin using an ex vivo porcine ear model. Methods: Curcumin microemulsions with different compositions were prepared and analyzed for their physicochemical properties. The dermal penetration efficacy of curcumin was evaluated from the different formulations and compared with non-microemulsion formulations. Results: Findings proved that microemulsion formulations improve the dermal penetration efficacy for curcumin when compared with non-microemulsion formulations. The composition of the microemulsion affects the penetration efficacy of curcumin and increases with decreasing oil content and increasing surfactant and water content. The best penetration for curcumin is achieved with a microemulsion that contained 7.7 g of medium-chain triglycerides as the oil phase, 6.92 g of Tween^® 80 and 62.28 g of ethanol as the surfactant mixture, and 23.1 g water. Conclusions: The present study provides a foundational basis for further development of different microemulsion formulations for enhancing the dermal penetration of poorly water-soluble active compounds.

Background/Objectives: Streptococcus pneumoniae (S. pneumoniae) is a major pathogen causing severe infectious diseases, with an escalating issue of antimicrobial resistance that threatens the efficacy of existing antibiotics. Given the challenges in developing traditional antibiotics, drug repurposing strategies offer a novel approach to address the resistance crisis. This study aims to evaluate the antibacterial and anti-biofilm activities of the approved non-antibiotic anticancer drug carmofur against multidrug-resistant S. pneumoniae, and investigate the mechanism of action, and assess therapeutic potential in vivo. Methods/Results: Antimicrobial tests revealed that carmofur exhibited strong antibacterial activity against multidrug-resistant S. pneumoniae strains, with minimum inhibitory concentrations (MICs) ranging from 0.25 to 1 µg/mL. In the biofilm detection experiments, carmofur not only inhibited the formation of biofilms, but also effectively removed biofilms under high concentration conditions. Mechanistic studies showed that carmofur disrupted bacterial membrane permeability and decreased intracellular ATP levels. Molecular docking and dynamics simulation assays indicated that carmofur could stably bind to thymidylate synthase through hydrogen bonding and hydrophobic interactions, thereby exerting antibacterial effects. Meanwhile, carmofur was able to repress the expression of the thyA gene at the mRNA level. In a mouse infection model, the carmofur treatment group showed a reduction of approximately two log levels in bacterial load in lung tissue and blood, a significant decrease in the levels of inflammatory cytokines TNF-α and IL-6, and an improvement in survival rate to 60%. Conclusions: In summary, carmofur demonstrated significant antibacterial and anti-biofilm activities against multidrug-resistant S. pneumoniae and showed good anti-infective effects in vivo, suggesting its potential clinical application as a therapeutic agent against drug-resistant bacteria.

Background: The development of nanostructured materials for cancer therapy has garnered significant interest due to their unique physicochemical properties, including enhanced surface area and tunable electronic structures, which can facilitate targeted drug delivery and oxidative stress modulation. This study investigates the anticancer potential of monoclinic silver dimolybdate nanorods (m-Ag₂Mo₂O₇) against aggressive breast (MDA-MB-231) and prostate (PC-3) cancer cells and explores their in vivo pharmacokinetic behavior. Methods: m-Ag₂Mo₂O₇ nanorods were synthesized via a hydrothermal method and characterized using XRD, SEM, Raman, and FTIR spectroscopy. In vitro cytotoxicity was evaluated using MTT assays on MDA-MB-231 and PC-3 cell lines across concentrations ranging from 1.56 to 100 µg/mL. In vivo biodistribution and radiopharmacokinetics were assessed using technetium-99m-labeled nanorods in male Swiss rats, with gamma counting employed for tissue uptake analysis and pharmacokinetic parameter determination. Results: m-Ag₂Mo₂O₇ nanorods exhibited a modest cytotoxic effect on MDA-MB-231 cells, with 50 µg/mL reducing cell viability by 23.5% (p < 0.05), while no significant cytotoxicity was observed in PC-3 cells. In vivo studies revealed predominant accumulation in the stomach, liver, spleen, and bladder, indicating reticuloendothelial system uptake and renal clearance. Pharmacokinetic analysis showed a rapid systemic clearance (half-life ~6.76 h) and a low volume of distribution (0.0786 L), suggesting primary retention in circulation with minimal off-target diffusion. Conclusions: While m-Ag₂Mo₂O₇ nanorods display limited standalone cytotoxicity, their ability to induce oxidative stress and favorable pharmacokinetic profile support their potential as adjuvant agents in cancer therapy, particularly for chemoresistant breast cancers. Further studies are warranted to elucidate their molecular mechanisms, optimize combinatorial treatment strategies, and assess long-term safety in preclinical models. Full article

Background: Ischemic heart disease (IHD), a leading cause of cardiovascular morbidity and mortality, continues to challenge modern medicine. Bombyx mori (Abresham), a traditional ingredient in Unani medicine, has shown promise in cardiovascular health, but its molecular mechanisms remain poorly understood. Methods: To explore the therapeutic potential of Bombyx mori for IHD, an integrative molecular simulation approach was applied. Network pharmacology was employed to identify the most favorable target receptor for the disease. Molecular docking simulations evaluated the binding affinities of chemical and protein-based compounds from Bombyx mori to the selected receptor. Molecular dynamics (MD) simulations confirmed the stability of these interactions under physiological conditions. Pharmacophore modeling identified key structural features critical for bioactivity, while in silico toxicity assessments evaluated the safety profiles of the compounds. Results: Key bioactive compounds from Bombyx mori, including Menaquinone-7, Quercetin, and Behenic acid, showed strong interactions with the target receptor, ACE2. The MD-based MM/PBSA calculations revealed the binding free energy values of Menaquinone-7 (−35.12 kcal/mol), Quercetin (−29.38 kcal/mol), and Behenic acid (−27.76 kcal/mol), confirming their strong binding affinity. Protein-based compounds, such as Chorion class high-cysteine HCB protein 13 (−212.43 kcal/mol), Bombyxin A-5 (−209.36 kcal/mol), and FMRFamide-related peptides (−198.93 kcal/mol), also displayed promising binding affinities. In silico toxicity assessments revealed favorable safety profiles for most compounds. Conclusions: This study positions Bombyx mori as a promising source of therapeutic agents for IHD. Future work should focus on experimental validation of these computational findings through in vitro and in vivo studies. Full article

Two-dimensional (2D) cine imaging is essential in routine clinical cardiac MR (CMR) exams for assessing cardiac structure and function. Traditional cine imaging requires patients to hold their breath for extended periods and maintain consistent heartbeats for optimal image quality, which can be challenging for those with impaired breath-holding capacity or irregular heart rhythms. This study aims to systematically assess the performance of a deep learning-based reconstruction (Sonic DL Cine, GE HealthCare, Waukesha, WI, USA) for accelerated cardiac cine acquisition. Multiple retrospective experiments were designed and conducted to comprehensively evaluate the technique using data from an MR-dedicated extended cardiac torso anatomical phantom (digital phantom) and healthy volunteers on different cardiac planes. Image quality, spatiotemporal sharpness, and biventricular cardiac function were qualitatively and quantitatively compared between Sonic DL Cine-reconstructed images with various accelerations (4-fold to 12-fold) and fully sampled reference images. Both digital phantom and in vivo experiments demonstrate that Sonic DL Cine can accelerate cine acquisitions by up to 12-fold while preserving comparable SNR, contrast, and spatiotemporal sharpness to fully sampled reference images. Measurements of cardiac function metrics indicate that function measurements from Sonic DL Cine-reconstructed images align well with those from fully sampled reference images. In conclusion, this study demonstrates that Sonic DL Cine is able to reconstruct highly under-sampled (up to 12-fold acceleration) cine datasets while preserving SNR, contrast, spatiotemporal sharpness, and quantification accuracy for cardiac function measurements. It also provides a feasible approach for thoroughly evaluating the deep learning-based method. Full article
