Background
Bauhinia racemosa is not familiarly known in Asian countries due to its limited existence and lack of medicinal information. It is commonly used as a medicine, ornamental plant, fence plant, and fodder for livestock since ancient times. It is also used as a landfill tree to avoid soil erosion of the forest.
Main body
In South India, people cultivate this plant in their premises in order to protect themselves from the effects of thunder. In this review, the various research prospects of this plant have been analyzed and are summarized. The aim of this review is to provide the traditional uses, phytochemicals and pharmacological activities of B. racemosa, and to highlight the current pharmacological developments of this medicinal plant.
Conclusions
The B. racemosa has immense therapeutic potential for treating diseases with both traditional and pharmacological applications. But many traditional uses of B. racemosa have not been validated by current investigations in the aspects of pharmaceutical. Until now, research on phyto-constituents from B. racemosa has not been done in an extensive way. Hence, the identified phytochemicals of B. racemosa should also be subjected to pharmacological studies to illuminate the biological mechanisms of these unreported secondary metabolites for the prevention of diseases or microbial infections and other health disorders of human and animal races.
Dengue fever has become one of the deadliest infectious diseases and requires the development of effective antiviral therapies. It is caused by members of the Flaviviridae family, which also cause various infections in humans, including dengue fever, tick-borne encephalitis, West Nile fever, and yellow fever. In addition, since 2019, dengue-endemic regions have been grappling with the public health and socio-economic impact of the ongoing coronavirus disease 19. Co-infections of coronavirus and dengue fever cause serious health complications for people who also have difficulty managing them. To identify the potentials of mangiferin, a molecular docking with various dengue virus proteins was performed. In addition, to understand the gene interactions between human and dengue genes, Cytoscape was used in this research. The Kyoto Encyclopedia of Genes and Genomes software was used to find the paths of Flaviviridae. The Kyoto Encyclopedia of Genes and Genomes and the Reactome Pathway Library were used to understand the biochemical processes involved. The present results show that mangiferin shows efficient docking scores and that it has good binding affinities with all docked proteins. The exact biological functions of type I interferon, such as interferon-α and interferon-β, were also shown in detail through the enrichment analysis of the signaling pathway. According to the docking results, it was concluded that mangiferin could be an effective drug against the complications of dengue virus 1, dengue virus 3, and non-structural protein 5. In addition, computational biological studies lead to the discovery of a new antiviral bioactive molecule and also to a deeper understanding of viral replication in the human body. Ultimately, the current research will be an important resource for those looking to use mangiferin as an anti-dengue drug.

Stem cell-based tissue engineering holds much hope for the development of multifunctional tissues to replace diseased organs. The attachment and survival of stem cells on a three-dimensional (3D) scaffold must be enhanced for faster progression of stem cell based tissue engineering. This study evaluate the stability of mesenchymal stem cells (MSCs) in 3D porous scaffolds composed of a collagen and chitosan blend impregnated with epidermal growth factor incorporated chitosan nanoparticles (EGF-CNP). The EGF-CNP scaffolds were characterized by transmission electron microscopy, which revealed that the nanoparticles were round in shape and 20 ~ 50 nm in size. The scaffolds were prepared by freeze drying. A Fourier-transform infrared spectrum study revealed that the linkage between collagen and chitosan was through an ionic interaction. Thermal analysis and degradation studies showed that the scaffold could be used in tissue engineering application. MSCs proliferated well in the EGF-CNP impregnated scaffold. A scanning electron microscope study showed anchored and elongated MSCs on the EGF-CNP impregnated scaffold. A 3D biodegradable collagen chitosan scaffold impregnated with EGF-CNP is a promising transportable candidate for MSC-based tissue engineering, and this scaffold could be used as an in vitro model for subsequent clinical applications.
