Novel biodegradable hydrogel scaffold based on hydroxyapatite eggshell, collagen, and epigallocatechin-3-gallate
No full textBackground: Biodegradable hydrogel scaffold is one of the crucial characteristics that determine the success of pulp regeneration. The degradation should be suitable for the growth of new tissue establishment. The aim of this study is to synthesize and compare the novel biodegradable hydrogel scaffold based on hydroxyapatite (HAp) eggshell, collagen, and epigallocatechin-3-gallate (HAp-Col-EGCG) with different HAp concentrations in vitro.
Materials and Methods: This study is original research. HAp-Col-EGCG hydrogel scaffolds were prepared using 1:1, 1:2, and 1:4 ratios of collagen and HAp with 10 μmol/L EGCG. The samples were freeze-dried and immersed in phosphate buffer saline containing lysozyme enzyme. The dried samples were weighed to determine the percentage of biodegradation value (P < 0.05).
Results: The result showed HAp-Col-EGCG was biodegradable but it has not been concluded that it can be completely eliminated. The data were analyzed by one-way analysis of variance and it indicated significant differences in percentage values.
Conclusion: Hydrogel scaffold based on HAp-Col-EGCG can be degraded and have the potential to be used as a biodegradable scaffold in supporting tissue regeneration

Dalam penelitian ini menunjukkan bahwa efek samping DMPA yang paling sering terjadi adalah adalah perubahan berat badan, ini menjadi salah satu keluhan utama responden. Bagi responden yang mengalami efek samping DMPA sebaiknya mengkonsultasikan kepada petugas kesehatan sebelum memilih alat kontrasepsi dan untuk petugas kesehatan agar dapat meningkatkan pelayanan, memberikan penyuluhan dalam memilih kontrasepsi yang tepat.
Kata Kunci: Efek Samping (Gangguan siklus haid, Depresi, Keputihan, Jerawat, Rambut rontok, Perubahan berat badan, Pusing dan Mual muntah), Kontrasepsi suntik DMPA, Ibu usia subur

A Two-Chamber Soft Actuator With An Expansion Limit Line for Force Enhancement
No full textSoft pneumatic actuators (SPAs) that can perform three-dimensional movements are being developed to perform more diverse tasks beyond simple bending. The conventional PneuNet actuators have expansion limit layers, which can obtain more tip force by limiting the expansion of the bottom. However, the presence of the expansion limit layer impedes other motions, such as rotation, when configured with multiple channels. In this study, we propose a two-chamber PneuNet actuator (TPA) to which the expansion limit line (ELLINE) is applied to obtain a force gain without a limitation on rotational motion due to the expansion limit layer. We perform a finite element analysis (FEA) on three designs that can rotate and bend using twochamber to find the optimal design. The effects on twisting, bending, and tip force according to the width of the ELLINE on the selected design were then verified through an FEA. After measuring rotation and bending for the fabricated actuator with and without the ELLINE. In the case of the fabricated TPA with the ELLINE, the bending decreased by 19.8%. However, rotation increased by 22.8 %, tip force increased by 1.53 times (with the ELLINE the force is 2.77 N in 70 kPa; without the ELLINE it is 1.8 N in 70 kPa), and grasping force increased by 5 times (with the ELLINE the force is 500 gf in 70 kPa, without the ELLINE it is 100 gf in 70 kPa). Furthermore, we fabricated a gripper using three actuators, capable of holding a weight of 505 g and objects of various shapes.FALSEsciescopu

The Toxicity Assessment of The Nanohydroxyapatite, Epigalocathecine-3-Gallate, And Hydroxyprophil Methylcellulose Hydrogel
No full textThe previous study showed that the hydroxyapatite, Epigalocathecine-3-Gallate (EGCG), and hydroxypropyl methylcellulose (HAp-EGCG-HPMC) material has the potential to be combined into a useful material in the field of dentistry, and one of them is as a pulp regeneration material. To determine the safety of the HAp-EGCG-HPMC formulation, the characterization of this new material should be performed using the cytotoxicity and proliferation test. It can show the number of living cells and it can indicate the vitality mechanism in certain proteins, also knowing the cell survival after exposure to HAp-EGCG-HPMC material. The method used to detect cell proliferation is commonly similar to the viability test. The cytotoxicity and proliferation were performed Methods: The HAp-EGCG-HPMC hydrogel was made by dissolving hydroxyapatite powder in distilled water to make a concentration of 1%, 2%, 4% with 10μmol/mL EGCG, and hydroxypropyl methylcellulose carriers were added. The cytotoxicity and proliferation in fibroblast cells of HA-EGCG-HPMC hydrogel was done using by CCK-8 dye and read by spectrophotometer with 450nm wavelength. Results: Hydroxyapatite, EGCG, and HPMC hydrogels were nontoxic to fibroblast cells 24 hours after mixing and it can induce proliferation of fibroblast cells. Conclusion: The hydrogel containing hydroxyapatite, EGCG, and HPMC is non-toxic and promotes the proliferation of fibroblast cells, making it suitable as a material for pulp regeneration
Diametral Tensile Strength of Microhybrid and Nanohybrid Composite Resins
No full text
Introduction: Microhybrid and nanohybrid composite resins are commonly used due to their high diametral tensile strength, which indicates the resistance of a material to chewing in posterior tooth restoration. Both composite resins have been widely produced via various modifications of their composition.
Objectives: To evaluate the diametral tensile strength of composite resins with microhybrid and nanohybrid fillers.
Methods: In this experimental laboratory study, microhybrid (DenFilTM) and nanohybrid (DenFilTM N) composite resins were shaped into 10 specimens each in cylindrical molds (6 mm diameter × 3 mm height) by the bulk-fill technique, and the upper layer was flattened using mylar strips and then polymerized using a light-curing unit for 20 s. Then, composite resin samples were immersed in cell culture plates filled with 2.5 mL of artificial saliva in a 37°C incubator for 24 h. Dimensions of the soaked specimens were examined using a digital caliper and tested using a universal testing machine.
Results: The diametral tensile strength values for microhybrid and nanohybrid composite resins were 41.67 MPa and 45.42 MPa, respectively.
Conclusion: There was no significant difference in the diametral tensile strength of microhybrid and nanohybrid
