A mild and efficient procedure for the synthesis of synthetic approach for creating 2, 4-thiazolidinedione derivatives through the Knoevenagel condensation reaction, substituted benzaldehyde with 2,4-thiazolidinedione in ethanol catalysed by Ferric chloride and DABCO as a versatile and effective catalyst. These 2, 4-thiazolidinedione derivatives are significant due to their diverse biological activities’ significant advantages, such as cost-effectiveness, non-toxicity, and operational simplicity and high yield.
There has been a rise in interest in terpenoids due to their variety of chemical forms and their distinct biological features, providing a range of applications in various industries, and enabling a significant economic, social, and environmental value. A systematic review was conducted based on the results of the collected scientific articles using Web of Science, Scopus, Scielo, Science Direct, and PubMed databases. This article examines the characteristics of terpenoids and their biological effects, concentrating on their anti-aging effects. Additionally, it discusses the various industrial applications and drawbacks of their application. Thanks to their activity, terpenoids play a significant part in various industries, making them important compounds with a wide range of applications. They are also frequently used and have excellent development prospects. emphasizing in particular their anti-aging qualities. Future research should focus on terpenoids’ broad toxicity, their catalytic mechanism, bioavailability, pharmacodynamics, biomarkers, extensive examinations of their bioactive qualities, and their usage in various industries in light of their effectiveness.
Analyzes the effect of β-Carotene (BC) in the processes of differentiation of adipose tissue Human Mesenchymal Stem Cells (hADMSCs) and dental pulp Human Mesenchymal Stem Cells (hDPMSCs) for obtaining Insulin-Producing Cells (IPCs). The BC present in the methanolic extract was analyzed and quantified by UV-VIS, TLC and HPLC methods. The cell viability test was done by flow cytometry, a concentration of 1.5 μM of BC or AP extract no cytotoxic effect on stem cells, so this concentration was used for the Human Mesenchymal Stem Cells (hMSCs) differentiation protocols for obtaining IPCs. The differentiation tests were done with the AP extract or β-carotene standard addition which demonstrates the increased cell differentiation percentages by the presence of intracellular insulin. This was more outstanding in the hMSCs that were stimulated with the AP in stage 3 and applied at all stages mainly in hDPMSCs, reaching up to 74% of the insulin-positive population respect to 11% where the molecules were not added. RT-PCR was performed for the level of gene expression like MAFA, PDX1 and NKX6.1 and those are found well expressed on differentiated cells. This could be relevant in cell therapy in diabetes, where inclusion of AP extracts or BC may improve yield of IPCs.
Radiographs have been a very essential tool for diagnosis as well as prognosis and treatment planning in dentistry. However, there are various limitations associated with the use of 2 dimensional radiographs which are most commonly used. The use of 3 dimensional radiographs has a number of advantages over the conventional techniques, especially in the field of periodontics. This review aims to shed light on the importance of CBCT as a diagnostic aid in routine periodontal practice.
This study explores the use of Syzygium cumini (L.) Skeels plant aqueous leaf extract as a reducing agent, which enables the green synthesis and comprehensive characterization of silver nanoparticles (AgNPs). The results indicated that the synthesized AgNPs were spherical in shape with an average size of 27.5 nm and a silver content of approximately 43.18%. The AgNPs exhibited promising antidiabetic and wound-healing properties. The antidiabetic activity, measured through glucose uptake and α-amylase inhibition assays, showed values of 80.08% and 83.91%, respectively. Additionally, the cytotoxicity assessment revealed that the AgNPs exhibited good biocompatibility even at higher doses, indicating their lower toxicity profile. Furthermore, the AgNPs demonstrated wound-closure percentages of 27.59% and 92.48% at 12 h and 24 h respectively, post-treatment, indicating that they were as effective as that of the standard ascorbic acid. These findings suggest that Syzygium cumini-mediated AgNPs have significant potential for applications in antidiabetic and wound-healing treatments.
