Abstract
Nanofibers (NFs) with practical drug-loading capacities, high stability, and controllable release have caught the attention of investigators due to their potential applications in on-demand drug delivery devices. Developing novel and efficient multidisciplinary management of locoregional cancer treatment through the design of smart NF-based systems integrated with combined chemotherapy and hyperthermia could provide stronger therapeutic advantages. On the other hand, implanting directly at the tumor area is a remarkable benefit of hyperthermia NF-based drug delivery approaches. Hence, implantable smart hyperthermia NFs might be very hopeful for tumor treatment in the future and provide new avenues for developing highly efficient localized drug delivery systems. Indeed, features of the smart NFs lead to the construction of a reversibly flexible nanostructure that enables hyperthermia and facile switchable release of antitumor agents to eradicate cancer cells. Accordingly, this study covers recent updates on applications of implantable smart hyperthermia NFs regarding their current scope and future outlook. This article is categorized under: Implantable Materials and Surgical Technologies > Nanomaterials and Implants.

Abstract
Drug-eluting stents (DESs) are drug-coated vascular implants that inhibit smooth muscle cell proliferation and limit in-stent re-stenosis. However, traditional DESs release a single drug into the blood and cannot cope with complex mechanisms in atherosclerosis and body responses. The present study aimed to develop a novel multimodal stent by fabricating asymmetric coating with electrophoretic deposition and electrospinning. Herein, we use heparin-loaded alginate (Hep/Alg) and atorvastatin calcium-loaded polyurethane (AtvCa/PU) coatings on the stent luminal and abluminal surfaces, respectively. Scanning electron microscopy (SEM) micrographs showed that the alginate coatings had uniformity and thin thickness. Meanwhile, the PU fibers were formed without beads, with an acceptable diameter and suitable mechanical properties. PU nanofiber revealed minimal degradation in a 1-month study. The release of AtvCa and Hep continued for 8 days without a significant initial burst release. None of the stent coatings were cytotoxic or hemolytic, and PU nanofibers supported the survival of human umbilical endothelial cells (HUVEC) with high adhesion and flattened morphologies. The results indicate that electrophoretic deposition and electrospinning have significant potential for achieving asymmetric coating on stents and a promising approach for dual drug release for multimodal effects in vascular stent applications.

Abstract
The field of tissue engineering continues to advance, sometimes in exponential leaps forward, but also sometimes at a rate that does not fulfill the promise that the field imagined a few decades ago. This review is in part a catalog of success in an effort to inform the process of innovation. Tissue engineering has recruited new technologies and developed new methods for engineering tissue constructs that can be used to mitigate or model disease states for study. Key to this antecedent statement is that the scientific effort must be anchored in the needs of a disease state and be working toward a functional product in regenerative medicine. It is this focus on the wildly important ideas coupled with partnered research efforts within both academia and industry that have shown most translational potential. The field continues to thrive and among the most important recent developments are the use of three-dimensional bioprinting, organ-on-a-chip, and induced pluripotent stem cell technologies that warrant special attention. Developments in the aforementioned areas as well as future directions are highlighted in this article. Although several early efforts have not come to fruition, there are good examples of commercial profitability that merit continued investment in tissue engineering. Impact statement Tissue engineering led to the development of new methods for regenerative medicine and disease models. Among the most important recent developments in tissue engineering are the use of three-dimensional bioprinting, organ-on-a-chip, and induced pluripotent stem cell technologies. These technologies and an understanding of them will have impact on the success of tissue engineering and its translation to regenerative medicine. Continued investment in tissue engineering will yield products and therapeutics, with both commercial importance and simultaneous disease mitigation.

Abstract
Gold nanoparticles, paclitaxel (PTX), and camptothecin (CMPT) were loaded into the PVA/κ-carrageenan/pegylated-PU composite and core–shell nanofibers prepared by two-nozzle and coaxial electrospinning methods. The capability of composite and core–shell nanofibers was investigated for the targeted delivery of anticancer drugs in lung cancer treatment. In vitro and in vivo release of PTX and CMPT were investigated to find the release mechanism from nanofibers compared to direct administration of pristine PTX and CMPT. The mean fiber diameter for composite and core–shell nanofibers with shell feeding rates of 0.3, 0.5, and 0.7 mL h−1 was about 225, 330, 520, and 640 nm, respectively. In vivo release studies indicated that the blood concentration of CMPT and PTX for rats fed with core–shell nanofibers reached the highest values of 26.8 ± 0.04 μg mL−1, and 26.5 ± 0.05 μg mL−1 in 36 h, and 24 h and reduced slowly within 84 h, and 48 h, respectively. The maximum cytotoxicity was 75% in the presence PVA/κ-carrageenan/CMPT/Au/pegylated-PU/PTX core–shell nanofibers. In vivo antitumor activity results confirmed the synergic effect of Au, CMPT and PTX anticancer drugs on the reduction of tumor volume without change in mouse weight by the PVA/κ-carrageenan/CMPT/Au/pegylated PU/PTX core–shell nanofibers. The obtained results indicated that the simultaneous loading of CMPT and PTX anticancer drugs and Au nanoparticles is more beneficial for lung cancer treatment.

Abstract
On-demand drug-delivery systems using nanofibers are extensively applicable for customized drug release based on target location and timing to achieve the desired therapeutic effects. A nanofiber formulation is typically created for a certain medication and changing the drug may have a significant impact on the release kinetics from the same delivery system. Nanofibers have several distinguishing features and properties, including the ease with which they may be manufactured, the variety of materials appropriate for processing into fibers, a large surface area, and a complex pore structure. Nanofibers with effective drug-loading capabilities, controllable release, and high stability have gained the interest of researchers owing to their potential applications in on-demand drug delivery systems. Based on their composition and drug-release characteristics, we review the numerous types of nanofibers from the most recent accessible studies. Nanofibers are classified based on their mechanism of drug release, as well as their structure and content. To achieve controlled drug release, a suitable polymer, large surface-to-volume ratio, and high porosity of the nanofiber mesh are necessary. The properties of nanofibers for modified drug release are categorized here as protracted, stimulus-activated, and biphasic. Swellable or degradable polymers are commonly utilized to alter drug release. In addition to the polymer used, the process and ambient conditions can have considerable impacts on the release characteristics of the nanofibers. The formulation of nanofibers is highly complicated and depends on many variables; nevertheless, numerous options are available to accomplish the desired nanofiber drug-release characteristics.

Abstract
Implantable thermo-responsive drug-loaded magnetic nanofibers (NFs) have attracted great interest for localized thermo-chemotherapy of cancer tissue/cells. From this perspective, smart polymeric electrospun NFs co-loaded with magnetic nanoparticles (MNPs) and a natural polyphenol anticancer agent, curcumin (CUR), were developed to enhance the local hyperthermic chemotherapy against melanoma, the most serious type of skin cancer. CUR/MNPs-loaded thermo-sensitive electrospun NFs exhibited alternating magnetic field (AMF)-responsive heat generation and "ON-OFF" switchable heating capability. Besides, corresponding to the reversible alterations in the swelling ratio, the "ON-OFF" switchable discharge of CUR from the magnetic NFs was detected in response to the "ON-OFF" switching of AMF application. Due to the combinatorial effect of hyperthermia and release of CUR after applying an AMF ("ON" state) for 600 s on the second and third days of incubation time, the viability of the B16F10 melanoma cancer cells exposed to the CUR/MNPs-NFs was reduced by 40% and 17%, respectively. Taken together, the macroscopic and nanoscale features of the smart NFs led to the creation of a reversibly adjustable structure that enabled hyperthermia and facile switchable release of CUR for eradication of melanoma cancer cells.

Abstract
An electromagnetic energy source in the radio-frequency range delivers power to a stent circuit via resonant inductive coupling, allowing a thermally triggered release of gel via Joule heating. A gold-electroplated, medical-grade stainless steel stent, serving as the base of the prototype device, melts a coating made from an emulsion composed mainly of dodecanoic acid. These coated devices produce wirelessly controllable releases of a gel into thermally regulated, stirred water that is near body temperature. The gel is made from salt, water, and gelatine from porcine skin and used to simulate drug release in this study. Thus, this system serves as a proof of concept to show the viability of controlling local drug delivery using this prototype device. Dodecanoic acid, a fatty acid, has a phase transition from solid to liquid near 43[Formula: see text]C and has relatively good biocompatibility. The average melting temperature of two different emulsions was 40.8±0.7[Formula: see text]C, a suitable value for the targeted application. Demonstration of controllable releases used electromagnetic pulses of approximately 180 seconds in duration, illustrating reproducibility of a controllable release phase while remaining relatively inert in the absence of stimuli. Releases were observable through measuring the conductivity of the water, the water temperature, and the stent temperature. This electrothermally active stent device enables wirelessly controlled local delivery with controlled dosage and timing, a concept with a wide range of potential applications. Some relevant examples include inhibiting restenosis or cancer treatment via targeted chemotherapy.

Abstract
Poly (ethyl-2) cyanoacrylate was used to create an adhesion-free biocompatible non-woven material reinforced by polyurethane core via a co-axial electrospinning set-up. The effect of relative humidity (RH) of (18, 30, 40, 60, and 68) % on the electrospinning process was examined, and found that in order to achieve well defined core-shell fiber structure, the optimal RH was 18%. If the RH is >18%, a phenomenon called Taylor cone cyclic destabilization occurs, which results in unfavorable surface and mechanical properties of the mat. The developed composite electrospun mat has the potential to be used in medical devices, such as repairing the viscera layer for intraperitoneal hernia mesh implants, which require the attenuation of biological elements, and adequate mechanical properties.

Abstract
In the present study, the magnetic MIL-53 nanometal organic framework particles (NMOFs) were incorporated into poly(acrylic acid) grafted-chitosan/polyurethane (PA-g-CS/PU) core-shell nanofibers for controlled release of temozolomide (TMZ) and paclitaxel (PTX) against U-87 MG glioblastoma cells during chemotherapy/hyperthermia combined method. The synthesized magnetic MIL-53 NMOFs and NMOF-loaded nanofibers were characterized using X-ray diffraction (XRD), Brunauer-Emmett-Teller (BET), Fourier transformed infrared (FTIR), vibrating-sample magnetometer (VSM) and scanning electron microscopy (SEM) analysis. The TMZ and PTX release profiles from magnetic MIL-53 5 wt% loaded-CS-g-PAA-PTX-TMZ/PU fibers were investigated under acidic and physiological pH at temperatures of 37 and 43 °C. The effect of hyperthermia on the release rate of TMZ and PTX from magnetic nanofibers was investigated. An alternating magnetic field could induce the mild hyperthermia (43 °C) for the cells treated with magnetic MIL-53 5 wt% loaded-CS-g-PAA-PTX-TMZ/PU fibers during 10 min. The release data were best described by the non-Fickian diffusion of Korsmeyer-Peppas equation. The cell viability, flowcytometry and Bcl-2, Bax expression levels were investigated to obtain the optimum nanofibrous carrier for apoptosis of U-87 MG cells in vitro. The obtained results indicated that the synthesized magnetic MIL-53 NMOFs loaded- PA-g-CS/PU/TMZ-PTX nanofibers (shell flow rate: 0.8 mLh-1) could be used as a targeted delivery of anticancer agents with maximum apoptosis of 49.6% of U-87 MG glioblastoma cells under AMF during chemotherapy/hyperthermia combination therapy.

Abstract
Magnetic hyperthermia (MHT) is being investigated as a cancer treatment since the 1950s. Recent advancements in the field of nanotechnology have resulted in a notable increase in the number of MHT studies. Most of these studies explore MHT as a stand-alone treatment or as an adjuvant therapy in a preclinical context. However, despite all the scientific effort, only a minority of the MHT-devoted nanomaterials and approaches made it to clinical context. The outcome of an MHT experiment is largely influenced by a number of variables that should be considered when setting up new MHT studies. This review highlights and discusses the main parameters affecting the outcome of preclinical MHT, aiming to provide adequate assistance in the design of new, more efficient MHT studies.

Abstract
Curcumin, a yellow-colored polyphenol extracted from the rhizome of turmeric root, is commonly used as a spice and nutritional supplement. It exhibits many pharmacological activities such as anti-inflammatory, anti-bacterial, anti-cancer, anti-Alzheimer, and anti-fungal. However, the therapeutic application of curcumin is limited by its extremely low solubility in aqueous buffer, instability in body fluids, and rapid metabolism. Nano delivery system has shown excellent potential to improve the solubility, biocompatibility and therapeutic effect of curcumin. In this review, we focus on the recent development of nano encapsulated curcumin and its potential for biomedical applications.

Abstract
The poly (ε-caprolactonediol) based polyurethane (PCL-Diol-b-PU)/poly(N-isopropylacrylamide)-grafted-chitosan (PNIPAAm-g-chitosan) core-shell nanofibers were synthesized via coaxial electrospinning process. Paclitaxel and 5-FU anticancer drugs were incorporated into the core of nanofibers. The nanofibers surface was coated using magnetic gold nanoparticles and the potential of synthesized nanofibers was investigated for the sustained release of paclitaxel and 5-FU toward 4T1 breast cancer cells death in vitro and in vivo. The synthesized magnetic nanoparticles were characterized using SEM, TEM, XRD and DLS analysis. The surface morphology of nanofibers was studied under various applied voltage and different shell flow rates. The paclitaxel and 5-FU release profiles from nanofibers were examined under acidic and physiological pH. The maximum 4T1 cell killing was found to be 78% using magnetic gold coated-nanofibers in the presence of external magnetic field. The SEM images after incubation of nanofibers in 4T1 breast cancer cells indicated the well adhesion of cells on the nanofibers surface. The in vivo studies showed that the tumor volume did not change during 10 days. The minimum increase in tumor volume was obtained using paclitaxel and 5-FU loaded-nanofibers coated by the magnetic gold nanoparticles. The obtained results demonstrated the high therapeutic efficiency of synthesized nanofibrous carrier toward breast cancer treatment.

Abstract
Stainless steel as a biomedical implant material has been studied in various fields and in various forms, such as vascular stents, bone plates, dental screws, and artificial hip and bone material. In this study, we used polycaffeic acid (PCA), a natural phenolic compound, to coat the surface of medical grade stainless steel to provide added potential medicinal effects by virtue of its inherent anti-inflammatory, antiviral, antifibrosis, antithrombosis, and antihypertensive characteristics. We did this via UV irradiation under an alkaline state to solve the cost and time problems of other existing coating methods. The physicochemical properties of the samples were investigated through field emission scanning electron microscopy (FESEM), atomic force microscopy (AFM), contact angle, FTIR, and X-ray photoelectron spectroscopy (XPS). Surface bioactivity using NIH-3T3 cell lines were observed in vitro. We expect that the proposed methodology may contribute to the field of study of implantable metallic devices.

Abstract
The objective of this study was to develop and characterize a novel intravaginal membrane platform for pH-triggered release of nanoparticles (NPs), which is essential for efficient intravaginal delivery of certain effective but acid-labile therapeutic agents for sexually transmitted infections, such as small interfering RNA (siRNA). A pH-responsive polyurethane (PU) was electrospun into a porous nanofibrous membrane. The diameters of the fibers, as well as the thickness and pore sizes of the membrane under dry and wet conditions (pH 4.5 and 7.0), were determined from scanning electron microscopy (SEM) micrographs. pH-dependent zeta-potential (ζ) of the membrane was evaluated using a SurPASS electrokinetic analyzer. Visiblex™ color-dyed polystyrene NPs (PSNs, 200 nm, COOH) and CCR5 siRNA-encapsulated solid lipid NPs (SLNs) were used for in vitro NP release studies in a vaginal fluid simulant (VFS) at pH 4.5 (normal physiological vaginal pH) and 7.0 (vaginal pH neutralization by semen). During 24 h of incubation in VFS, close-to-zero PSNs (2 ± 1%) and 28 ± 4% SLNs were released through the PU membrane at pH 4.5, whereas the release of PSNs and SLNs significantly increased to 60 ± 6% and 59 ± 8% at pH 7.0, respectively. The pH-responsive release of NPs hinged on the electrostatic interaction between the pH-responsive membrane and the anionic NPs, and the change in pH-responsive morphology of the membrane. In vitro biocompatibility studies of the membrane showed no significant cytotoxicity to VK2/E6E7 human epithelial cells and Sup-T1 human T-cells and no significant changes in the expression of pro-inflammatory cytokines (IL-6, IL-8, and IL-1β). Overall, the porous pH-responsive PU membrane demonstrated its potential in serving as a "window" membrane in reservoir-type intravaginal rings (IVRs) for pH-responsive intravaginal release of NPs. STATEMENT OF SIGNIFICANCE: Stimuli-responsive intravaginal nanoparticle release is achieved for the first time through a new electrospun pH-responsive polyurethane (PU) semi-permeable membrane, which can serve as a "window" membrane in the reservoir-type IVR for the prevention of human immunodeficiency virus (HIV) transmission. Almost no release of nanoparticles was observed at normal pH in the female genital tract (in vaginal fluid simulant [VFS], at pH 4.5); however, a continuous release of NPs was observed at elevated pH in the female genital tract (in VFS, at pH 7.0). This pH-responsive intravaginal release can reduce side effect and drug resistance by avoiding unnecessary exposure. The PU semi-permeable membrane demonstrated potential use as biomaterials for "smart" intravaginal nanoparticle release and has great potential to protect women from HIV.

Abstract
In order to meet the unmet medical needs for effective cancer treatment, multifunctional nanocarriers based on iron oxide nanoparticles hold tremendous promise. Here we report a superparamagnetic iron oxide nanoparticles based hexa-functional nanosystem for synergistic cancer theranostic applications by offering active tumour targeting, accumulation and complementary imaging capability by combining magnetic resonance imaging as well as near-infrared fluorescence, magnetophotothermia and chemotherapy. The uniquely designed nanosystem exhibited a paramount increase in the antitumour efficacy through the simultaneous application of multiple thermal effects called magnetophotothermia, which outweighed the therapeutic efficacy of the current thermo-chemo therapies or stand-alone therapies. The active tumour-seeking property with prolonged tumour accumulation and complementary imaging capability with improved sensitivity and resolution also augments the therapeutic efficacy of the proposed nanosystem. Additionally, the work proposes a deep-learning-based tumour cell nuclei detection technique from H&E stained images in anticipation of providing much inspiration for the future of precision histology.

Abstract
In spite of remarkable improvements in cancer treatments and survivorship, cancer still remains as one of the major causes of death worldwide. Although current standards of care provide encouraging results, they still cause severe systemic toxicity and also fail in preventing recurrence of the disease. In order to address these issues, biomaterial-based implantable drug delivery systems (DDSs) have emerged as promising therapeutic platforms, which allow local administration of drugs directly to the tumor site. Owing to the unique properties of biopolymers, they have been used in a variety of ways to institute biodegradable implantable DDSs that exert precise spatiotemporal control over the release of therapeutic drug. Here, the most recent advances in biopolymer-based DDSs for suppressing tumor growth and preventing tumor recurrence are reviewed. Novel emerging biopolymers as well as cutting-edge polymeric microdevices deployed as implantable antitumor DDSs are discussed. Finally, a review of a new therapeutic modality within the field, which is based on implantable biopolymeric DDSs, is given.

Abstract
In the present work composite membranes were produced by combining magnetic nanoparticles (NPs) with cellulose acetate (CA) membranes for magnetic hyperthermia applications. The non-woven CA membranes were produced by electrospinning technique, and magnetic NPs were incorporated by adsorption at fibers surface or by addition to the electrospinning solution. Therefore, different designs of composite membranes were obtained. Superparamagnetic NPs synthesized by chemical precipitation were stabilized either with oleic acid (OA) or dimercaptosuccinic acid (DMSA) to obtain stable suspensions at physiological pH. The incorporation of magnetic NP into CA matrix was confirmed by scanning and transmission electron microscopy. The results showed that adsorption of magnetic NPs at fibers' surface originates composite membranes with higher heating ability than those produced by incorporation of magnetic NPs inside the fibers. However, adsorption of magnetic NPs at fibers' surface can cause cytotoxicity depending on the NPs concentration. Tensile tests demonstrated a reinforcement effect caused by the incorporation of magnetic NPs in the non-woven membrane.

Abstract
Chemothermal brachytherapy seeds have been developed using a combination of polymeric dual drug chemotherapy and alternating magnetic field induced hyperthermia. The synergistic effect of chemotherapy and hyperthermia brachytherapy has been investigated in a way that has never been performed before, with an in-depth analysis of the cancer cell inhibition property of the new system. A comprehensive in vivo study on athymic mice model with SCC7 tumor has been conducted to determine optimal arrays and specifications of the chemothermal seeds. Dual drug chemotherapy has been achieved via surface deposition of polydopamine that carries bortezomib, and also via loading an acidic pH soluble hydrogel that contains 5-Fluorouracil inside the chemothermal seed; this increases the drug loading capacity of the chemothermal seed, and creates dual drug synergism. An external alternating magnetic field has been utilized to induce hyperthermia conditions, using the inherent ferromagnetic property of the nitinol alloy used as the seed casing. The materials used in this study were fully characterized using FESEM, H1 NMR, FT-IR, and XPS to validate their properties. This new approach to experimental cancer treatment is a pilot study that exhibits the potential of thermal brachytherapy and chemotherapy as a combined treatment modality.

Abstract
This article reviews stimuli-responsive and biostable polyurethanes (PUs) and discusses biomedical applications of smart PUs with a particular focus on long-term implantable PU biomaterials such as PU generated artificial blood vessels, artificial intervertebral discs (IVDs), and intravaginal rings (IVRs). Recently, smart PUs have been actively researched to enhance bioactivity, biocompatibility, and reduce drug side effects. Although biodegradability is important in regenerative medicine, biostability of PU plays a key role for long-term implantable biomaterials. This article reviews recent publications of research and inventions of stimuli-responsive and biostable PUs. Applications of smart PUs in long-term implantable biomaterials are discussed and linked to the future outlook of smart biostable PU biomaterials.

Abstract
Oxygen deficiency after myocardial infarction (MI) leads to massive cardiac cell death. Protection of cardiac cells and promotion of cardiac repair are key therapeutic goals. These goals may be achieved by re-introducing oxygen into the infarcted area. Yet current systemic oxygen delivery approaches cannot efficiently diffuse oxygen into the infarcted area that has extremely low blood flow. In this work, we developed a new oxygen delivery system that can be delivered specifically to the infarcted tissue, and continuously release oxygen to protect the cardiac cells. The system was based on a thermosensitive, injectable and fast gelation hydrogel, and oxygen releasing microspheres. The fast gelation hydrogel was used to increase microsphere retention in the heart tissue. The system was able to continuously release oxygen for 4 weeks. The released oxygen significantly increased survival of cardiac cells under the hypoxic condition (1% O2) mimicking that of the infarcted hearts. It also reduced myofibroblast formation under hypoxic condition (1% O2). After implanting into infarcted hearts for 4 weeks, the released oxygen significantly augmented cell survival, decreased macrophage density, reduced collagen deposition and myofibroblast density, and stimulated tissue angiogenesis, leading to a significant increase in cardiac function.

Abstract
Magnetic nanofiber has been widely applied in biomedical fields due to its distinctive size, morphology, and properties. We proposed a novel needleless electrospinning method to prepare magnetic nanofibers from the self-assembling "Taylor cones" of poly(vinyl pyrrolidone) (PVP)/Fe₃O₄ ferrofluid (PFF) under the coincident magnetic and electric fields. The results demonstrated that a static PFF Rosensweig instability with a conical protrusion could be obtained under the magnetic field. The tip of the protrusion emitted an electrospinning jet under the coincident magnetic and electric fields. The needleless electrospinning showed a similar process phenomenon in comparison with conventional electrospinning. The prepared nanofibers were composed of Fe₃O₄ particles and PVP polymer. The Fe₃O₄ particles aggregated inside and on the surface of the nanofibers. The nanofibers prepared by needleless electrospinning exhibited similar morphology compared with the conventionally electrospun nanofibers. The nanofibers also exhibited good ferromagnetic and magnetic field responsive properties.

Abstract
Gastrointestinal malignancies have been a tremendous problem in the medical field and cover a wide variety of parts of the system, (i.e. esophagus, duodenum, intestines, and rectum). Usually, these malignancies are treated with palliation with the use of non-vascular nitinol stents. However, stenting is not a perfect solution for these problems. While it can enhance the quality of life of the patient, in time the device will encounter problems such as re-occlusion due to the rapid growth of the tumor. In this study, we propose a functionalization technique using electropolymerization of polydopamine directly onto the nitinol stent struts for the combined application of hyperthermia and chemotherapy. The coating was characterized using FESEM, XPS, and FT-IR. Drug release studies show that facile release of the anticancer drug BTZ from the surface of the polydopamine-coated stent could be achieved by the dissociation between catechol groups of polydopamine and the boronic acid functionality of BTZ in a pH-dependent manner. The anti-cancer property was also evaluated, and cytotoxicity on ESO26 and SNU-5 cancer cell lines were observed. Our results suggest that the introduced approach can be considered as a potential method for therapeutic stent application.

Abstract
Here, we investigate crack propagation initiated from an initial notch in a self-healing material. The crack propagation in the core-shell nanofiber mats formed by coelectrospinning and the composites reinforced by them is in focus. All samples are observed from the crack initiation until complete failure. Due to the short-time experiments done on purpose, the resin and cure released from the cores of the core-shell nanofibers could not achieve a complete curing and stop crack growth, especially given the fact that no heating was used. The aim is to elucidate their effect on the rate of crack propagation. The crack propagation speed in polyacrylonitrile (PAN)-resin-cure nanofiber mats (with PAN being the polymer in the shell) was remarkably lower than that in the corresponding monolithic PAN nanofiber mat, down to 10%. The nanofiber mats were also encased in polydimethylsiloxane (PDMS) matrix to form composites. The crack shape and propagation in the composite samples were studied experimentally and analyzed theoretically, and the theoretical results revealed agreement with the experimental data.

Abstract
Following myocardial infarction (MI), degradation of extracellular matrix (ECM) by upregulated matrix metalloproteinases (MMPs) especially MMP-2 decreases tissue mechanical properties, leading to cardiac function deterioration. Attenuation of cardiac ECM degradation at the early stage of MI has the potential to preserve tissue mechanical properties, resulting in cardiac function increase. Yet the strategy for efficiently preventing cardiac ECM degradation remains to be established. Current preclinical approaches have shown limited efficacy because of low drug dosage allocated to the heart tissue, dose-limiting side effects, and cardiac fibrosis. To address these limitations, we have developed a MMP-2 inhibitor delivery system that can be specifically delivered into infarcted hearts at early stage of MI to efficiently prevent MMP-2-mediated ECM degradation. The system was based on an injectable, degradable, fast gelation, and thermosensitive hydrogel, and a MMP-2 specific inhibitor, peptide CTTHWGFTLC (CTT). The use of fast gelation hydrogel allowed to completely retain CTT in the heart tissue. The system was able to release low molecular weight CTT over 4 weeks possibly due to the strong hydrogen bonding between the hydrogel and CTT. The release kinetics was modulated by amount of CTT loaded into the hydrogel, and using chondroitin sulfate and heparin that can interact with CTT and the hydrogel. Both glycosaminoglycans augmented CTT release, while heparin more greatly accelerated the release. After it was injected into the infarcted hearts for 4 weeks, the released CTT efficiently prevented cardiac ECM degradation as it not only increased tissue thickness but also preserved collagen composition similar to that in the normal heart tissue. In addition, the delivery system significantly improved cardiac function. Importantly, the delivery system did not induce cardiac fibrosis. These results demonstrate that the developed MMP-2 inhibitor delivery system has potential to efficiently reduce adverse myocardial remodeling and improve cardiac function.
