Engineering periodontal tissue interfaces using multiphasic scaffolds and membranes for guided bone and tissue regeneration. BIOMATERIALS ADVANCES 2024; 157:213732. [PMID: 38134730 DOI: 10.1016/j.bioadv.2023.213732] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/22/2023] [Revised: 12/06/2023] [Accepted: 12/11/2023] [Indexed: 12/24/2023]
Abstract
Periodontal diseases are one of the greatest healthcare burdens worldwide. The periodontal tissue compartment is an anatomical tissue interface formed from the periodontal ligament, gingiva, cementum, and bone. This multifaceted composition makes tissue engineering strategies challenging to develop due to the interface of hard and soft tissues requiring multiphase scaffolds to recreate the native tissue architecture. Multilayer constructs can better mimic tissue interfaces due to the individually tuneable layers. They have different characteristics in each layer, with modulation of mechanical properties, material type, porosity, pore size, morphology, degradation properties, and drug-releasing profile all possible. The greatest challenge of multilayer constructs is to mechanically integrate consecutive layers to avoid delamination, especially when using multiple manufacturing processes. Here, we review the development of multilayer scaffolds that aim to recapitulate native periodontal tissue interfaces in terms of physical, chemical, and biological characteristics. Important properties of multiphasic biodegradable scaffolds are highlighted and summarised, with design requirements, biomaterials, and fabrication methods, as well as post-treatment and drug/growth factor incorporation discussed.

Abstract
The growing number of diseases in the past decade has once again highlighted the need for extensive research on the development of novel drugs. There has been a major expansion in the number of people suffering from malignant diseases and types of life-threatening microbial infections. The high mortality rates caused by such infections, their associated toxicity, and a growing number of microbes with acquired resistance necessitate the need to further explore and develop the synthesis of pharmaceutically important scaffolds. Chemical entities derived from biological macromolecules like carbohydrates and lipids have been explored and observed to be effective agents in the treatment of microbial infections and diseases. These biological macromolecules offer a variety of chemical properties that have been exploited for the synthesis of pharmaceutically relevant scaffolds. All biological macromolecules are long chains of similar atomic groups which are connected by covalent bonds. By altering the attached groups, the physical and chemical properties can be altered and molded as per the clinical applications and needs, this ring them potential candidates for drug synthesis. The present review establishes the role and significance of biological macromolecules by articulating various reactions and pathways reported in the literature.

Gels 2022; 8:gels8090526. [PMID: 36135239 PMCID: PMC9498735 DOI: 10.3390/gels8090526] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/24/2022] [Revised: 08/16/2022] [Accepted: 08/19/2022] [Indexed: 11/22/2022] Open
Abstract
Localized delivery systems have been typically designed to enhance drug concentration at a target site and minimize systemic drug toxicity. A rosin/cinnamon oil (CO) in situ forming gel (ISG) was developed for the sustainable delivery of imatinib mesylate (IM) against colorectal cancer cells. CO has been claimed to express a potent anticancer effect against various cancer cells, as well as a synergistic effect with IM on colorectal cancer cells; however, poor aqueous solubility limits its application. The effect of rosin with the adding CO was assessed on physicochemical properties and in vitro drug release from developed IM-loaded rosin/CO-based ISG. Moreover, in vitro cytotoxicity tests were conducted against two colorectal cancer cells. All formulations exhibited Newtonian flow behavior with viscosity less than 266.9 cP with easier injectability. The adding of CO decreased the hardness and increased the adhesive force of the obtained rosin gel. The gel formation increased over time under microscopic observation. CO-added ISG had a particle-like gel appearance, and it promoted a higher release of IM over a period of 28 days. All tested ISG formulations revealed cytotoxicity against HCT-116 and HT-29 cell lines at different incubation times. Thus, CO-loaded rosin-based ISG can act as a potentially sustainable IM delivery system for chemotherapy against colorectal cancer cells.

Effect of Rosin Modification on the Visual Characteristics of Round Bamboo Culm. Polymers (Basel) 2021; 13:polym13203500. [PMID: 34685258 PMCID: PMC8541177 DOI: 10.3390/polym13203500] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/14/2021] [Revised: 09/30/2021] [Accepted: 10/07/2021] [Indexed: 12/02/2022] Open
Abstract
Rosin was used to treat round bamboo culm using the impregnation method. The quantitative color and gloss measurements combined with a qualitative eye tracking experiment were used to evaluate the effect of rosin treatment under different temperatures on the visual characteristics of the bamboo surface. Surface morphology analysis was also used to explore the mechanism of modification. The results showed that proper heating of the modified system was conducive to the formation of a continuous rosin film, which increased the gloss value. The maximum gloss value of 19.6 achieved at 50 °C was 122.7% higher than the gloss value of the control group. Heating decreased the brightness of the bamboo culm and changed the color from the green and yellow tones to red and blue. Additionally, at temperatures higher than 60 °C, the bamboo epidermal layer was damaged or shed, and stripes formed on the culm surface. The density of these stripes increased with an increase in treatment temperature. Eye movement experiment and subjective evaluation showed that high gloss would produce dazzling feeling, such as at 50 °C, while low gloss will appear dim, such as at 80 °C, while the gloss at 40 °C and 60 °C were appropriate. Additionally, the solid color surface below 60 °C had a large audience of about 73%, and the striped surface above 60 °C was preferred by 27% of the subjects.

Determination of Temperature-Dependent Coefficients of Viscosity and Surface Tension of Tamarind Seeds ( Tamarindus indica L.) Polymer. Polymers (Basel) 2021; 13:polym13040610. [PMID: 33670569 PMCID: PMC7923174 DOI: 10.3390/polym13040610] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2020] [Revised: 02/12/2021] [Accepted: 02/15/2021] [Indexed: 11/25/2022] Open
Abstract
The rheological properties of tamarind seed polymer are characterized for its possible commercialization in the food and pharmaceutical industry. Seed polymer was extracted using water as a solvent and ethyl alcohol as a precipitating agent. The temperature’s effect on the rheological behavior of the polymeric solution was studied. In addition to this, the temperature coefficient, viscosity, surface tension, activation energy, Gibbs free energy, Reynolds number, and entropy of fusion were calculated by using the Arrhenius, Gibbs–Helmholtz, Frenkel–Eyring, and Eotvos equations, respectively. The activation energy of the gum was found to be 20.46 ± 1.06 kJ/mol. Changes in entropy and enthalpy were found to be 23.66 ± 0.97 and −0.10 ± 0.01 kJ/mol, respectively. The calculated amount of entropy of fusion was found to be 0.88 kJ/mol. A considerable decrease in apparent viscosity and surface tension was produced when the temperature was raised. The present study concludes that the tamarind seed polymer solution is less sensitive to temperature change in comparison to Albzia lebbac gum, Ficus glumosa gum and A. marcocarpa gum. This study also concludes that the attainment of the transition state of viscous flow for tamarind seed gum is accompanied by bond breaking. The excellent physicochemical properties of tamarind seed polymers make them promising excipients for future drug formulation and make their application in the food and cosmetics industry possible.

Abstract
Recently, there has been a rapid growth of using bio-based materials in pharmaceutical applications, due to their low cost and availability. In this study, natural composition of cellaburate (cellulose-ester) and colophony (pine-resin) was used to prepare films to control ibuprofen release from its amorphous solid dispersion. The effect of two preparation technologies of spin-coating and hot-melt-extrusion was studied on the physicochemical properties and in vitro dissolution/release behavior. Physical stability was evaluated for 12 w at 54 %RH/22 °C. Characterization involved using PLM/DSC/MTDSC/ATRFTIR/TGA/SEM and PXRD. Ibuprofen was amorphously-dispersed at 30 %(w/w) in 35:65 colophony:cellaburate films. Spin-films were more physically stable over 12 w; however, controlled release of ibuprofen was achieved mainly from hot-melt-extruded-films for 5 h. Both films have shown first-order release kinetics; whereby polymeric swelling and relaxation likely governed the release. The successful preparation of cellaburate-colophony platform that has achieved tunable release profiles of poorly water-soluble drug holds the potential for further drug delivery development.

Abstract
With continual rapid developments in the biomedical field and understanding of the important mechanisms and pharmacokinetics of biological molecules, controlled drug delivery systems (CDDSs) have been at the forefront over conventional drug delivery systems. Over the past several years, scientists have placed boundless energy and time into exploiting a wide variety of excipients, particularly diverse polymers, both natural and synthetic. More recently, the development of nano polymer blends has achieved noteworthy attention due to their amazing properties, such as biocompatibility, biodegradability and more importantly, their pivotal role in controlled and sustained drug release in vitro and in vivo. These compounds come with a number of effective benefits for improving problems of targeted or controlled drug and gene delivery systems; thus, they have been extensively used in medical and pharmaceutical applications. Additionally, they are quite attractive for wound dressings, textiles, tissue engineering, and biomedical prostheses. In this sense, some important and workable natural polymers (namely, chitosan (CS), starch and cellulose) and some applicable synthetic ones (such as poly-lactic-co-glycolic acid (PLGA), poly(lactic acid) (PLA) and poly-glycolic acid (PGA)) have played an indispensable role over the last two decades for their therapeutic effects owing to their appealing and renewable biological properties. According to our data, this is the first review article highlighting CDDSs composed of diverse natural and synthetic nano biopolymers, blended for biological purposes, mostly over the past five years; other reviews have just briefly mentioned the use of such blended polymers. We, additionally, try to make comparisons between various nano blending systems in terms of improved sustained and controlled drug release behavior.

Abstract
In this work, different materials for three-dimensional (3D)-printing were studied, which based on polycaprolactone with two natural additives, gum rosin, and beeswax. During the 3D-printing process, the bed and extrusion temperatures of each formulation were established. After, the obtained materials were characterized by mechanical, thermal, and structural properties. The results showed that the formulation with containing polycaprolactone with a mixture of gum rosin and beeswax as additive behaved better during the 3D-printing process. Moreover, the miscibility and compatibility between the additives and the matrix were concluded through the thermal assessment. The mechanical characterization established that the addition of the mixture of gum rosin and beeswax provides greater tensile strength than those additives separately, facilitating 3D-printing. In contrast, the addition of beeswax increased the ductility of the material, which makes the 3D-printing processing difficult. Despite the fact that both natural additives had a plasticizing effect, the formulations containing gum rosin showed greater elongation at break. Finally, Fourier-Transform Infrared Spectroscopy assessment deduced that polycaprolactone interacts with the functional groups of the additives.

Abstract
Natural polymers are widely used in biomedical applications because of their numerous effects. Especially, plant-derived natural polymers extracted from cell walls, especially wood, which is abundant, inexpensive and nontoxic to cells, have high mechanical strength to retain their turgor pressure. Plant-derived polymers are also unaffected by enzymes present in the human body, having a strong possibility to create a polymeric structure that releases drugs only exactly where needed. Therefore, plant-derived polymers are suitable for use in drug delivery systems (DDS) as they have durability with few drug leakage issues in the body. Here, to improve drug incorporation and release efficiency, we prepared a multilayer nanofilm from tannic acid (TA) and lignin extracted from plants and wood. We used a strategy involving film degradation by tannase and laccase, which are not present in humans, to depolymerize TA and lignin, respectively. The TA and lignin film was highly stable for 7 days at pH 3-7 and was readily degraded after enzyme treatment. We also observed controllable drug release and anticancer effect from the TA and lignin hollow carriers depending on enzymatic activity. By taking advantage of plant-derived polymers and non-toxic enzymatic reactions, we have demonstrated the film growth and degradation mechanism in depth and explored their use in a smart DDS with easily controlled release kinetics, which is useful as a DDS platform.

Abstract
Polymers are essential tools in the research and development of new therapeutic devices. The diversity and flexibility of these materials have generated high expectations in the composition of new materials with extraordinary abilities, especially in the design of new systems for the modified release of pharmaceutically active ingredients. The natural polymer rosin features moisture protection and pH-dependent behavior (i.e., it is sensitive to pH > 7.0), suggesting its possible use in pharmaceutical systems. The synthetic polymer Eudragit® RS PO is a low-permeability material, the disintegration of which depends on the time of residence in the gastrointestinal tract. The present study developed a polymeric material with desirable physicochemical characteristics and synergistic effects that resulted from the inherent properties of the associated polymers. Isolated films were obtained by solvent evaporation and subjected to a water vapor transmission test, scanning electron microscopy, calorimetry, Fourier transform-infrared (FT-IR) spectroscopy, micro-Raman spectroscopy, and mechanical analysis. The new polymeric material was macroscopically continuous and homogeneous, was appropriately flexible, had low water permeability, was vulnerable in alkaline environments, and was thermally stable, maintaining an unchanged structure up to temperatures of ∼400°C. The new material also presented potentially suitable characteristics for application in film coatings for oral solids, suggesting that it is capable of carrying therapeutic substances to distal regions of the gastrointestinal tract. These findings indicate that this new material may be added to the list of functional excipients.

Abstract
PEGylated rosin derivatives are improved in series ester-adduct derivatives of rosin. The aim of this study was to assess biodegradation and biocompatibility of PEGylated rosin derivatives. Study employed two different PEGylated rosin derivatives, namely, D1 and D2, with constant weight of rosin and increasing amounts of polyethylene glycol 400. PEGylated rosin derivatives were synthesized and tailored into spherical beads and disks with smooth surface for use. In vitro degradation was studied at pH 4.0, 7.4, and 10 for 60 days. In vivo study was performed in Wistar rats using poly(d,l-lactide- co-glycolide) (50:50) as a control. Post 3, 7, 14, and 21 days of implantation, PEGylated rosin derivatives disks were retrieved and evaluated for weight loss, molecular weight decline, morphology, and tissue response. D1 and D2 beads showed 21.68% and 32.37% weight loss, respectively, at pH 7.4 post 60 days. Degradation was increased substantially with increase in pH of medium. Degradation of disks was markedly slower than that of beads. In vivo degradation of PEGylated rosin derivative disks was faster than in vitro. Post 60 days of implantation, weight loss of D1 and D2 disk was 7.57% and 11.84%, whereas molecular weight was declined by about 19% and 26%, respectively. Owing to higher amounts of polyethylene glycol 400, in vitro and in vivo degradation of D2 was faster than D1. Poly(d,l-lactide- co-glycolide) as well as PEGylated rosin derivative implants evoked mild inflammatory responses characterized by few macrophages and absence of exudation at tissue–disk interface. The cellular density in tissue surrounding PEGylated rosin derivative disks increased initially with time up to 7 days and decreased eventually at the end of 21 days. The trend was similar for poly(d,l-lactide- co-glycolide) implants. Increase in polyethylene glycol 400 improved biodegradation and biocompatibility of PEGylated rosin derivatives. Results revealed that PEGylated rosin derivatives degrade slowly in vivo over a period of time, possess fair biocompatibility, and thus are promising biomaterial for drug delivery applications.

Abstract
Natural polysaccharides are getting increasing attention in the development of pharmaceutical dosage forms due to their encouraging reports on nontoxicity and biodegradability. Natural gums can also be engineered to have better materials for drug delivery system design. Gellan gum originates from microbial fermentation and has been declared as safe by US FDA for human consumption. It possesses gelling ability in presence of multivalent earth metal cations and thus enabled the design of mutiparticulate drug delivery systems in completely aqueous environment avoiding the use of organic solvents. Due to faster drug release profiles of divalent cation-induced gellan gum particles, nowadays chemically modified forms of gellan polysaccharide are currently being investigated for the controlled release of drugs. This chapter discusses the factors contributing to the varying gelling characteristics of gellan gum and the recent developments in its chemical modification towards the fabrication of novel controlled drug delivery devices.

Abstract
Gum exudates are among the oldest natural polymer. Natural gums have remained one of the major areas of interest for the researchers for their applicability in the drug delivery system because of their wide availability, inexpensiveness and availability in a variety of structures with varied properties. They can be easily modified chemically, biochemically and are highly stable, safe, non-toxic, gel forming and in addition are biodegradable. Rosin is one of the natural gums obtained as resinous constituent of the oleoresin exuded by various species of pine, mostly conifers. Rosin consists primarily of abietic- and pimaric-type resin acids (or rosin acids) with characteristic hydrophobic hydrophenanthrene rings which impart them excellent film-forming properties. Rosin and its derivatives are biopolymers that are increasingly used for their pharmaceutical applications. In the pharmaceutical field, it has been investigated for film-forming and coating properties, microencapsulation and as a matrix material in the tablets for sustained and controlled drug release. This article reviews the literature on rosin and its derivative and describes the varied applications of the rosin and their future exploitation in novel drug delivery systems.

Abstract
Present work was aimed at designing of phosphated cross-linked microspheres of bael fruit gum (BFG) by emulsification method using sodium-tri-meta phosphate as a cross-linking agent for treatment of colon cancer using 5-fluorouracil as model drug. Stirring speed was found to be 1,000 rpm for about 5 h to be optimal to obtain reproducible microspheres. It was found that there is an increase in particle size as polymer concentration is increased whereas a reduction in particle size was observed as there is increase in stirring speed. Cross-linked BFG microspheres were successfully prepared by emulsification method. Optimum surfactant concentration was found to be 2 % w/w. Scanning electron microscopy studies showed that the drug-loaded microspheres were non-aggregated and in spherical shape. Differential scanning calorimetry and Fourier transform infrared-spectroscopy studies showed that drug and excipients are compatible. Release studies showed that drug release was more profound in cecal medium induced with enzymes causing degradation of the cross linked BFG than that of the release showed in simulated intestinal fluid. Stability studies showed that there were no significant changes in the drug content and physical appearance of microspheres.

Abstract
Drug dosage forms contain many components in addition to the active pharmaceutical ingredient(s) to assist in the manufacturing process as well as to optimise drug delivery. Due to advances in drug delivery technology, excipients are currently included in novel dosage forms to fulfil specific functions and in some cases they directly or indirectly influence the extent and/or rate of drug release and absorption. Since plant polysaccharides comply with many requirements expected of pharmaceutical excipients such as non-toxicity, stability, availability and renewability they are extensively investigated for use in the development of solid oral dosage forms. Furthermore, polysaccharides with varying physicochemical properties can be extracted from plants at relatively low cost and can be chemically modified to suit specific needs. As an example, many polysaccharide-rich plant materials are successfully used as matrix formers in modified release dosage forms. Some natural polysaccharides have even shown environmental-responsive gelation characteristics with the potential to control drug release according to specific therapeutic needs. This review discusses some of the most important plant-derived polymeric compounds that are used or investigated as excipients in drug delivery systems.

Abstract
Rosin was partially esterified with polyethylene glycol 400 and reacted with maleic-anhydride to form an ester-adduct derivative. Derivative and native rosin were characterized for physicochemical properties. Aqueous coating system of derivative was developed by ammonia neutralization method. Organic-based films were produced using acetone. Aqueous and organic-based films were comparatively evaluated. Derivative exhibited an excellent coat-forming ability on spherical-units. Aqueous-based film exhibited very high water vapor transmission rate, wettability, water uptake, and leaching at pH 6.8. A 20% w/w aqueous-based coat could sustain diclofenac sodium release for 8 h, whereas, 20% w/w organic-based coat released 20.11% of drug in 8 h. In conclusion, aqueous coating system of synthesized rosin derivative can be developed; however, aqueous-coats are less efficient to retard the drug release rate. Instead, the organic-based coatings can efficiently be used for sustained drug delivery.

Abstract
The aim of this study was to investigate PEGylated rosin derivatives (PRDs) as microencapsulating materials for sustained drug delivery. PRDs (D1, D2, and D3) composed of a constant weight of rosin and varied amounts of polyethylene glycol (PEG) 400 and maleic anhydride were synthesized in the laboratory. Microparticles were prepared by the O/O solvent evaporation technique using the acetone/paraffin system. Diclofenac sodium (DFS) and diltiazem hydrochloride (DLTZ) were used as model drugs. The effect of the type of PRD, drug, PRD:drug ratio, viscosity of external phase, stirring speed, concentration of magnesium stearate (droplet stabilizer), and method of preparation on particle size, drug loading, and drug release profiles of microparticles was investigated. PRDs could produce discrete and spherical microspheres (with DFS) and microcapsules (with DLTZ). The drug loading value for microparticles was found to be in the range of 37.21% to 87.90%. The microparticle size range was 14 to 36 microm. The particle size and drug loadings of microparticles were substantially affected by the concentration of magnesium stearate and the type of drug, respectively. Most of the formulations could sustain the DFS and DLTZ release for 20 hours. DFS and DLTZ release from PRD microparticles followed Hixson-Crowell and first-order kinetics, respectively. The results suggest that PRDs can be used successfully to prepare discrete and spherical microparticles with DFS and DLTZ for sustained drug delivery.
