Abstract: Ayurveda, an ancient form of Indian medicine, speaks of several plant parts that cure different ailments when consumed. Here, we analyze different regularly consumed plant products to study their effect on mitosis. Several extracts were able to suppress mitosis, Areca nut was picked as a known mutagen, and turmeric and mango for their antimitotic activity upon eliminating other plant extracts. Preliminary analysis of a mixture of the mitogenic and antimitotic extracts showed that the antimitotic extracts were able to suppress the mitogenic activity of areca nut, indicating that the activity of areca nut is one of the factors that may be dependent on those targeted by mango and turmeric. Extracts prepared in absolute ethanol showed that the active ingredient is either inactive or absent in the ethanol extract. Two approaches were taken to identify the active ingredient. Firstly, the extracts were tested for the presence of known active ingredients, such as tannins, that are known to hav

Abstract: Silk fibroin from Thai Bombyx mori (Nangnoi Srisaket-I) cocoons was interested to use as biomaterial for tissue engineering scaffolds. In this paper, Thai silk fibroin based nanofibrous scaffolds were fabricated by electrospinning technique. The effects of electrospinning parameters, such as silk fibroin/formic acid solutions concentrations and applied voltage, on the morphology and mechanical properties of Thai silk fibroin based nanofibrous scaffold were investigated. Thai Silk fibroin (SF) sponges were dissolved in 98% formic acid with concentration of 20, 30, and 40 % (w/v) and spun into fibers at applied voltage of 15, 20, and 25 kV, respectively. The morphological and mechanical properties of SF-nanofibers were examined by field emission scanning electron microscopy (FESEM) and AFM indentation method. Electrospinning technique could produce nanofibers in the range of diameter from 100–300 nm. The concentration of silk fibroin solution was considered as the most important paramete
