Taheri M, Sousanabadi Farahani A. Experimental extraction of Young's modulus of gastric tissue with development of spherical, cylindrical, and crowned rollers contact theories. Heliyon 2024; 10:e31848. [PMID: 38867961 PMCID: PMC11167291 DOI: 10.1016/j.heliyon.2024.e31848] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2023] [Revised: 05/05/2024] [Accepted: 05/22/2024] [Indexed: 06/14/2024] Open
Abstract
Nanotechnology has been considered with the aim of recognizing the structural and mechanical properties as well as improving the treatment and diagnostic process in the field of medicine. The process of nanomanipulation by examining healthy and cancerous tissues in nanoscale is one of the processes used in this field. Therefore, in this article, considering the importance of recognizing the properties of cancerous and healthy tissues in improving the treatment and diagnosis process, one of the most common types of cancer has been studied. Young modulus has been used as a parameter in the diagnosis of cancerous tissue and its value has been calculated for gastric cancerous tissue. To achieve this goal, atomic force microscopy (AFM) was used during the manipulation process. This tool with the ability to study cancerous tissues in different environments and with the least amount of damage to the target tissue, is one of the effective tools in the field of nanomanipulation. The parameter studied in this study is the geometry of gastric cancer tissue. Therefore, the simulations have been performed by considering contact models with spherical, cylindrical and crowned rollers geometries. The force-indentation depth diagram for gastric tissue is plotted experimentally and compared with theoretical results. According to the experimental work done after reviewing the recorded topographic images, the approximate range of the Young's modulus value for gastric tissue has been calculated according to different geometries. Since the geometry of the crowned rollers is closer to the geometry of the gastric tissue, it has a higher accuracy and the values of the Young's modulus have been calculated according to this geometry in the range of 316-310 KPa.

NANOMATERIALS (BASEL, SWITZERLAND) 2024; 14:292. [PMID: 38334563 PMCID: PMC10856574 DOI: 10.3390/nano14030292] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 12/18/2023] [Revised: 01/25/2024] [Accepted: 01/27/2024] [Indexed: 02/10/2024]
Abstract
Banana (Musa acuminate) has been popular among consumers worldwide due to its rich nutrients and minerals. However, bananas are highly susceptible to the physical and biological factors that lead to postharvest loss during transportation and storage. In this work, novel sodium alginate (SA) films incorporated with silver nitroprusside nanoparticles (AgNNPs) were prepared to extend the shelf life of bananas through antibacterial and antioxidant coating. The results exhibited that AgNNPs were cubical and that their size was <500 nm, with metal composition being Ag and Fe. Additionally, the incorporation of AgNNPs in the SA film was seen in FE-SEM and zeta analysis, with an average size of about 365.6 nm. Furthermore, the functional and crystalline properties of AgNNPs were assessed through FTIR and XRD. Transmittance testing of the SA-AgNNPs films confirmed they have good UV barrier properties. SA-AgNNPs films exhibited excellent high antibacterial activity against foodborne pathogens including L. monocytogenes, S. enterica, and E. coli at the concentration of 500 µg/mL. Moreover, during the storage of bananas, SA-AgNNPs nanocomposite coatings act as a barrier to microbial contamination and slow down the ripening of bananas. As a result, compared with SA-coated and uncoated bananas, SA-AgNNPs-coated bananas exhibited the lowest weight loss and lowest total bacterial colonies, thus greatly extending their shelf life. Particularly when coated with SA-AgNNPs films, total bacterial colonies (TBC) in the banana peel and pulp were as low as 1.13 × 103 and 51 CUF/g on the ninth day of storage, respectively. Our work offers an efficient strategy to improve the quality of bananas during the postharvest period, with extensive applications in fruit preservation and food packing.

Abstract
Control of in situ 3D bioprinting of hydrogel without toxic crosslinker is ideal for tissue regeneration by reinforcing and homogeneously distributing biocompatible reinforcing agent during fabrication of large area and complex tissue engineering scaffolds. In this study, homogeneous mixing, and simultaneous 3D bioprinting of a multicomponent bioink based on alginate (AL)-chitosan (CH), and kaolin was obtained by an advanced pen-type extruder to ensure structural and biological homogeneity during the large area tissue reconstruction. The static, dynamic and cyclic mechanical properties as well as in situ self-standing printability significantly improved with the kaolin concentration for AL-CH bioink-printed samples due to polymer-kaolin nanoclay hydrogen bonding and cross-linking with less amount of calcium ions. The Biowork pen ensures better mixing effectiveness for the kaolin-dispersed AL-CH hydrogels (evident from computational fluid dynamics study, aluminosilicate nanoclay mapping and 3D printing of complex multilayered structures) than the conventional mixing process. Two different cell lines (osteoblast and fibroblast) introduced during large area multilayered 3D bioprinting have confirmed the suitability of such multicomponent bioinks for in vitro even tissue regeneration. The effect of kaolin to promote uniform growth and proliferation of the cells throughout the bioprinted gel matrix is more significant for this advanced pen-type extruder processed samples.

Abstract
This paper describes the development of a film comprising chitosan (CS), sodium alginate (SA), and ethyl cellulose (EC) for buccal mucosal administration. A film of CS-SA unidirectional release drug-containing water-repellent layer EC was produced by interfacial reaction solvent-drying technique using self-made equipment. The CS-SA-EC film had superior mechanical properties compared to CS-EC and SA-EC films. The existence of the amide bond was confirmed by FT-IR. DSC confirmed that the drug was dispersed in the carrier material in an amorphous form. The drug release studies emerged that the model drugs from CS-SA-EC films presented better release properties. The Ritger-Peppas model best describes all ratios of drugs release mechanisms. The permeability characteristics of the films were evaluated in the TR146 cells model and the rabbit buccal mucosae. The cumulative penetration amounts of the model drugs were significantly increased. The permeability mechanism of the film was studied preliminarily using immunofluorescence and Western Blot. The results showed that the film inhibited the expression of ZO-1 protein, and the expressive trend of ZO-1 protein was consistent with the results of in vitro permeation experiments. The pharmacokinetics of the drugs loaded films were evaluated and compared with oral administration in rats. The relative bioavailability of the model drugs was 246.00% (Zolmitriptan) and 142.12% (Etodolac) relative to oral administration. The results of this study demonstrate the potential of CS-SA-EC vehicle in buccal mucosa drug delivery.

Abstract
BACKGROUND Fluconazole (FLZ), a potent antifungal medication, is characterized by poor water solubility that reduced its antifungal efficacy. OBJECTIVE This study aimed to prepare FLZ-loaded polymeric nanoparticles (NPs) by using different polymers and techniques as a mean of enhancing the antifungal activity of FLZ. METHODS NP1, NP2, and NP3 were prepared by the double emulsion/solvent evaporation method using PLGA, PCL, and PLA, respectively. The ionotropic pre-gelation technique was applied to prepare an alginate/chitosan-based formulation (NP4). Particle size, zeta potential, encapsulation efficiency, and loading capacity were characterized. FT-IR spectra of FLZ, the polymers, and the prepared NPs were estimated. NP4 was selected for further in-vitro release evaluation. The broth dilution method was used to assess the antifungal activity of NP4 using a resistant clinical isolate of Candida albicans. RESULTS The double emulsion method produced smaller-sized particles (<390 nm) but with much lower encapsulation efficiency (< 12%). Alternatively, the ionic gelation method resulted in nanosized particles with a markedly higher encapsulation efficiency of about 40%. The FT-IR spectroscopy confirmed the loading of the FLZ molecules in the polymeric network of the prepared NPs. The release profile of NP4 showed a burst initial release followed by a controlled pattern up to 24 hours with a higher percent released relative to the free FLZ suspension. NP4 was able to reduce the value of MIC of FLZ by 20 times. CONCLUSION The antifungal activity of FLZ against C. albicans was enhanced markedly via its loading in the alginate/chitosan-based polymeric matrix of NP4.

Benefits of pH-responsive polyelectrolyte coatings for carboxymethyl cellulose-based microparticles in the controlled release of esculin. MATERIALS SCIENCE & ENGINEERING. C, MATERIALS FOR BIOLOGICAL APPLICATIONS 2020; 118:111397. [PMID: 33255002 DOI: 10.1016/j.msec.2020.111397] [Citation(s) in RCA: 14] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 06/02/2020] [Revised: 07/29/2020] [Accepted: 08/14/2020] [Indexed: 12/20/2022]
Abstract
Moderate and prolonged payload release in response to a particular factor is highly demanded for efficient carriers of low-molecular-weight, chemically unstable phytopharmaceuticals. Thus, the objective of our contribution was to establish the effect of pH-responsive polyelectrolyte coatings on the release properties of carboxymethyl cellulose-based microparticles designed to deliver phytopharmaceuticals through the gastrointestinal tract. Microparticles were fabricated via extrusion coupled with external gelation and further coated with polyelectrolytes (PEs) (chitosan, gelatin, or PAH and PSS) involving electrostatic interactions. Successful deposition of PEs was confirmed by FTIR, and their thickness and viscosity were characterized in terms of QCM-D and ellipsometric techniques. The encapsulation efficiency of esculin, used as a model phytopharmaceutical, as proven by UV-Vis studies, was over 57%. SEM and fluorescence microscopy revealed a micrometric size, a mostly spherical shape and an altered topography of the investigated microcapsules. The physical stability of the microcapsules in media of various pH values was confirmed with CLSM and gravimetric studies. Studies on human gingival fibroblasts in vitro revealed that the obtained microparticles did not induce any cytotoxic effects. Payload release was monitored in situ by means of CLSM and ex situ under gastrointestinal conditions in vitro. Mathematical evaluation of the microparticle release profiles using classical models led to the establishment of a new hybrid model that revealed the mechanism behind esculin release. We demonstrated that the application of a polyelectrolyte shell onto CMC-based microspheres may provide controlled delivery of the payload, with its release triggered by the pH and ionic strength of the medium. These observations suggest that the release manner of small-molecule glycosides under gastrointestinal conditions can be tailored by careful selection of suitable materials to obtain biocompatible and functional hydrogel microparticles.

Abstract
Hydrogels have captivated the attention of several research and industry segments, including bioengineering, tissue engineering, implantable/wearable sensors and actuators, bioactive agent delivery, food processing, and industrial processes optimization. A common limitation of these systems is their fixed shape. The concept of hydrogel moldability is often assigned to the injectability potential of liquid precursors, and this feature is often lost right after hydrogel formation. Hydrogel modulation is a recent trend that advocates the importance of designing materials with shape fitting ability targeting on-demand responses or defect filling purposes. Here, we present a compliant and cell encapsulation-compatible hydrogel prepared from unmodified natural origin polymers with the ability to undergo extreme sequential shape alterations with high recovery of its mechanical properties. Different fragments of these hydrogels could be bonded together in spatiotemporally controlled shape- and formulation-morphing structures. This material is prepared with affordable off-the-shelf polysaccharides of natural origin using a mild and safe processing strategy based solely on polyelectrolyte complexation followed by an innovative partial coacervate compaction and dehydration step. These unique hydrogels hold potential for multifield industrial and healthcare applications. In particular, they may find application as defect filling agents or highly compliant wound healing patches for cargo release and/or cell delivery for tissue regeneration and cell-based therapies.

Abstract
In vitro meat has recently emerged as a new concept in food biotechnology. Methods to produce in vitro meat generally involve the growth of muscle cells that are cultured on scaffolds using bioreactors. Suitable scaffold design and manufacture are critical to downstream culture and meat production. Most current scaffolds are based on mammalian-derived biomaterials, the use of which is counter to the desire to obviate mammal slaughter in artificial meat production. Consequently, most of the knowledge is related to the design and control of scaffold properties based on these mammalian-sourced materials. To address this, four different scaffold materials were formulated using non-mammalian sources, namely, salmon gelatin, alginate, and additives including gelling agents and plasticizers. The scaffolds were produced using a freeze-drying process, and the physical, mechanical, and biological properties of the scaffolds were evaluated. The most promising scaffolds were produced from salmon gelatin, alginate, agarose, and glycerol, which exhibited relatively large pore sizes (~200 μm diameter) and biocompatibility, permitting myoblast cell adhesion (~40%) and growth (~24 h duplication time). The biodegradation profiles of the scaffolds were followed, and were observed to be less than 25% after 4 weeks. The scaffolds enabled suitable myogenic response, with high cell proliferation, viability, and adequate cell distribution throughout. This system composed of non-mammalian edible scaffold material and muscle-cells is promising for the production of in vitro meat.

Abstract
Parathyroid hormone (PTH) is the only US Food and Drug Administration (FDA)-approved anabolic agent for the treatment of osteoporosis. The anabolic action of PTH depends on the mode of PTH administration. Pulsatile administration promotes bone formation, however continuous PTH exposure results in bone resorption. In addition, the therapeutic effect of PTH is optimal when the dose and duration fit the therapeutic window. Current PTH treatment requires daily injection, which is neither a convenient nor a favorable choice of patients. Here, an implantable and biodegradable device capable of long-term pulsatile delivery of PTH is developed as a patient-friendly alternative. The advanced materials and fabrication techniques developed in this work enable us to preprogram a pulsatile delivery device to systemically deliver 21 daily pulses of PTH that build bone in vivo. In addition, the device is biodegradable and absorbable in vivo so that no retraction procedure is needed. Therefore, this implantable and biodegradable pulsatile device holds promise to promote bone growth and treat various conditions of bone loss without the burden of daily injections or secondary surgeries.

Abstract
Optimization of mechanical properties is required in applications of tissue-engineered scaffolds. In this study, a polyelectrolyte complexation approach is proposed to improve the mechanical properties of the nanofibrous scaffolds. Through an electrospun chitosan/gelatin (CG) model system, it is demonstrated that the storage modulus of CG nanofiber-based complex membranes is over 10(3)-fold higher than that of neat chitosan or gelatin membranes. Further, an annealing process was found to promote the conjugation of the oppositely charged polymers and thus the tensile modulus of CG membranes is 1.9-fold elevated. When the molar ratio of aminoglucoside units in chitosan to carboxyl units in gelatin is 1:1, the complex nanofiber-based membranes (CG2) display the highest mechanical strength. In addition, the complex membranes reveal an excellent swelling capacity. By comparing the CG membranes electrospun with cast, it is deduced that the complexation is one of the main contributing factors to the improvement in mechanical properties. FTIR and DSC analyses confirm that more molecular interactions took place in the complexation. SEM observation clearly displays the electrospinnability of the complex. Therefore, polyelectrolyte complexation is an effective strategy for enhancing mechanical properties of nanofibrous scaffolds. These mechanically enhanced chitosan/gelatin nanofibrous membranes have wider applications than wound dressing.
