3D printing and bioprinting in the battle against diabetes and its chronic complications Indumathi Sathisaran Frontiers in Bioengineering and Biotechnology, 2024 Diabetes is a metabolic disorder characterized by high blood sugar. Uncontrolled blood glucose affects the circulatory system in an organism by intervening blood circulation. The high blood glucose can lead to macrovascular (large blood vessels) and microvascular (small blood vessels) complications. Due to this, the vital organs (notably brain, eyes, feet, heart, kidneys, lungs and nerves) get worsen in diabetic patients if not treated at the earliest. Therefore, acquiring treatment at an appropriate time is very important for managing diabetes and other complications that are caused due to diabetes. The root cause for the occurrence of various health complications in diabetic patients is the uncontrolled blood glucose levels. This review presents a consolidated account of the applications of various types of three-dimensional (3D) printing and bioprinting technologies in treating diabetes as well as the complications caused due to impaired blood glucose levels. Herein, the development of biosensors (for the diagnosis), oral drug formulations, transdermal drug carriers, orthotic insoles and scaffolds (for the treatment) are discussed. Next to this, the fabrication of 3D bioprinted organs and cell-seeded hydrogels (pancreas engineering for producing insulin and bone engineering for managing bone defects) are explained. As the final application, 3D bioprinting of diabetic disease models for high-throughput screening of ant-diabetic drugs are discussed. Lastly, the challenges and future perspective associated with the use of 3D printing and bioprinting technologies against diabetes and its related chronic complications have been put forward.
Investigating Cocrystallization of Carbamazepine with Structurally Compatible Coformers: New Cocrystal and Eutectic Phases with Enhanced Dissolution Indumathi Sathisaran, Sameer Vishvanath Dalvi AAPS Pharmscitech, 2021 In this work, carbamazepine (CBZ), an anticonvulsant drug was cocrystallized with several structurally complement coformers (coformers with amide, acid and hydrazide functional groups) to enhance its dissolution. CBZ formed a cocrystal phase with acetamide (ACE) when mixtures of CBZ and ACE (containing CBZ mole fractions, X CBZ of 0.25, 0.33, 0.5, and 0.67) were subjected to solid-state grinding (SSG), evaporative crystallization (EC), slurry conversion (SC), and slow cooling crystallization (SLC). Upon heating, the CBZ-ACE cocrystal phase formed from CBZ-ACE mixtures containing X CBZ of 0.25, 0.33 and 0.67 underwent solid-state phase transition to CBZ form I and CBZ cocrytsal phase obtained from the CBZ-ACE mixture containing X CBZ of 0.5 converted to CBZ form III. Interestingly, slow cooling cocrystallization experiments resulted in crystallization of a cocrystal as well as the CBZ dihydrate forms. The powder dissolution studies demonstrated that among the different CBZ-ACE-SSG cocrystal phases, CBZ-ACE-SSG-X CBZ -0.33 cocrystal exhibited 7.47 times improved dissolution whereas the CBZ eutectic phase with nicotinic acid hydrazide (NAH) exhibited 4.93 times increased dissolution when compared to raw CBZ.
Physical characterization of chitosan/gelatin-alginate composite beads for controlled release of urea Indumathi Sathisaran, Murugesan Balasubramanian Heliyon, 2020 Polymer-based controlled-release formulations are gaining significant advantage over chemical fertilizers in recent years as they contribute to the preservation of soil fertility by reducing soil pollution in farm lands. In this work, urea (a nitrogen source fertilizer) has been entrapped within chitosan-alginate and gelatin-alginate composite beads at three different concentrations. The physical properties of the polymer composite beads namely the diameter, porosity, yield percentage, Carr's index and Hausner's ratio were determined. These fertilizer-loaded beads were also characterized by Scanning Electron Microscopy (SEM) and Fourier Transform-Infra Red (FT-IR) spectroscopy. Urea enhanced swelling of chitosan-alginate beads through the creation of pores whereas in the case of gelatin-alginate formulations, urea decreased the swelling. The swelling of the polymer composite beads was found to be maximum at pH of 5.6 when compared to that of pH conditions, 7 and 8.5. The chitosan-alginate composite beads were found to possess better fertilizer entrapping efficiency than the gelatin-alginate composite beads. The in vitro urea release studies demonstrated that the urea-entrapped gelatin-alginate beads exhibited slower urea release than that of the chitosan-alginate beads. These controlled release urea formulations were found to follow quasi-fickian diffusion mechanism.
Effectiveness of oil-layered albumin microbubbles produced using microfluidic t-junctions in series for in vitro inhibition of tumor cells Aaqib H. Khan, Xinyue Jiang, Swarupkumar Surwase, Merve Gultekinoglu, Cem Bayram, Indumathi Sathisaran, Dhiraj Bhatia, Jubair Ahmed, Bingjie Wu, Kezban Ulubayram, Mohan Edirisinghe, Sameer V. Dalvi Langmuir, 2020 This work focuses on evaluation of the effectiveness of double layered microbubbles loaded with doxorubicin and curcumin for cell invasion arrest from 3D spheroid models of triple negative breast cancer (TNBC), MDA-MB-231 cell line. Albumin microbubbles coated in drug-laden oil layer were synthesized using a new method of connecting two microfluidic T-mixers in series. Double-layered microbubbles thus produced consist of an innermost core of nitrogen gas encapsulated in an aqueous layer of bovine serum albumin (BSA) which in turn, is coated with an outer layer of silicone oil. In order to identify the process conditions leading to the formation of double-layered microbubbles, a regime map was constructed based on Capillary numbers for aqueous and oil phases. The microbubble formation regime transitions from double-layered to single layer microbubbles and then to formation of single oil droplets upon gradual change in flow rates of aqueous and oil phases. In-vitro dissolution studies of double-layered microbubbles in an air-saturated environment indicated that a complete dissolution of such bubbles produces an oil droplet devoid of gas bubble. Incorporation of doxorubicin and curcumin was found to produce a synergistic effect, which resulted in higher cell deaths in 2D monolayers of TNBC cells and inhibition of cell proliferation from 3D spheroid models of TNBC cells compared to control.
New curcumin-trimesic acid cocrystal and anti-invasion activity of curcumin multicomponent solids against 3D tumor models Indumathi Sathisaran, Dhiraj Devidas Bhatia, Sameer Vishvanath Dalvi International Journal of Pharmaceutics, 2020 Curcumin (CUR) is a Biopharmaceutics Classification System (BCS) class IV drug with poor aqueous solubility and low permeability. The dissolution of CUR can be enhanced through the cocrystallization approach. In this work, we report a new cocrystal phase of CUR with trimesic acid (TMA) with the enhanced dissolution of CUR. Cytotoxicity and cell invasion assays were conducted on (2D) monolayers and three-dimensional (3D) tumor models of triple-negative breast cancer (TNBC) cells, MDA-MB-231 using the new CUR-TMA cocrystal phase along with different CUR solid forms prepared in our previous works. The cytotoxicity and internalization assays conducted on 2D monolayers indicated that all CUR multicomponent solid forms except Curcumin-Folic Acid Dihydrate (CUR-FAD) (1:1) coamorphous solid exhibited enhanced bioavailability than unprocessed CUR. Cell invasion assay conducted on 3D tumor spheroid models showed that Curcumin-Hydroxyquinol (CUR-HXQ) cocrystal completely inhibited cell invasion whereas CUR-FAD (1:1) coamorphous solid induced enhanced invasion of cells from spheroid models.
Cocrystallization of carbamazepine with amides: Cocrystal and eutectic phases with improved dissolution Indumathi Sathisaran, Sameer Vishvanath Dalvi Journal of Molecular Structure, 2019 Carbamazepine is an anticonvulsant drug which belongs to Biopharmaceutics Classification System (BCS) Class II drugs. In this work, attempts have been made to enhance the dissolution of carbamazepine (CBZ) in aqueous medium by attempting cocrystallization with the coformers such as para-hydroxybenzamide (PHBAD), salicylamide (SAL) and pyrazinamide (PRZ). Binary phase diagrams were constructed by conducting Differential Scanning Calorimetry (DSC) analysis for these CBZ-coformer pairs in order to determine the nature of the solid phase and cocrystal forming zone. CBZ formed a 1:1 cocrystal phase with PHBAD from the eutectic melts at a stoichiometric ratio of 1:1 and 1:2 whereas it formed eutectics with SAL as well as PRZ. Single crystals of CBZ-PHBAD (1:1) cocrystal phase were obtained by solvent evaporation of CBZ-PHBAD eutectic melts in Acetone-Toluene (1:1 vol ratio). Interestingly, recrystallization of eutectic melt of CBZ-PHBAD (1:1) in 1,4-Dioxane produced crystals of para-hydroxybenzamide monohydrate. Crystal structure analysis showed that CBZ-PHBAD (1:1) cocrystal and para-hydroxybenzamide monohydrate crystallized in monoclinic space groups namely P21/c and P21/n respectively. CBZ formed intermolecular interaction with two molecules of PHBAD via O-H…O hydrogen bonding and N-H...O intermolecular interaction which results into a cocrystal. Powder Dissolution (PD) studies were conducted for the CBZ-PHBAD (1:1) cocrystal, CBZ-SAL and CBZ-PRZ eutectic mixtures in Phosphate Buffer Saline (PBS) at 37 °C. Among the three carbamazepine solid forms, CBZ-PHBAD cocrystal exhibited 6.5 times higher dissolution than raw carbamazepine while the CBZ-SAL-SSG-XCBZ-0.5 eutectic and CBZ-PRZ-SSG-XCBZ-0.5 eutectic phases exhibited 2.62 and 3.05 times enhanced dissolution than raw carbamazepine.
