Authors: A. SHAMEELA KHADEEJA , JOHNEY JESTEENA , RAGUNATHAN R. 
Published: January 2023

Objective: To investigate the in vitro antioxidant, antimicrobial, anticancer, and wound healing properties of leaf extracts of Acanthus ilicifolius.
Methods: Acanthus ilicifolius leaves were dried and extracts were prepared using different solvents using cold extraction method. The preliminary phytochemical analysis and quantitative methods were carried out using standard procedures. In vitro antioxidant activity was evaluated using DPPH assay. Disc diffusion method was employed to determine the antimicrobial activities of the extracts. The methanolic extract was subjected to FTIR and GC-MS analysis for characterization of phytochemicals. This extract was further subjected to HPLC analysis for characterization and quantification. The antiproliferative effects of methanolic extract was determined using MTT assay and wound healing properties were determined using Cell migration assay.
Results: The highest levels of phenol and flavonoids were detected in aqueous extracts, followed by chloroform. Methanolic extract showed the highest antioxidant activity as well as significant antibacterial activity against Klebsiella pneumoniae and Staphylococcus aureus. Squalene, a metabolite with known pharmaceutical applications, was identified in GC-MS, which was further confirmed and quantified using HPLC analysis. The methanolic extract showed cytotoxic activity against the cervical cancer cell line and showed a significant beneficial effect on wound healing in the L929 cell line.
Conclusion: The results obtained in this study revealed that the leaf extracts of Acanthus ilicifolius possess potent antioxidant, antimicrobial, cytotoxic and wound-healing properties. These activities are due to bioactive components present in the extracts whose identification could lead to the development of new therapeutic agents.

Published: January 2023

Objective: Anti-aging formulations are among the premier skin care products in the global market that are in huge demand. Different treatments are available to slow down skin aging, but are very expensive and are often found to produce adverse reactions to the skin in prolong use. Hence, present study has been designed to formulate poly herbal anti-aging skin care products and their evaluation thereon.
Methods: Anti-aging herbal skin care cream, gel and serum were prepared using two medicinal plants Hippophae salicifolia and Celosia argentea along with three bioactives caffeine, rutin and bakuchiol. The formulations were evaluated for physicochemical parameters like pH, texture analysis, acid value, short-term stability study, etc. Phenolics and flavanoid content were determined. Anti-aging potential was gauged by in silico studies using the glide tool of ‘Schrodinger’.
Results: Cream, gel and serum showed good physical appearance and were free from gritty particles and with smooth texture. Accelerated stability studies indicated insignificant changes in physicochemical parameters of the formulations. Based on the docking score and interaction with amino acid, compounds present in the plant extracts and bioactive showed good anti-aging activity.
Conclusion: The prepared herbal anti-aging formulations were found to be stable and exhibited good potential as an anti-aging combination. So, they can be used as an effective combination to protect skin from aging.

Teknik analisis yang di gunakan statistik deskriptif, uji asumsi klasik dengan menggunakan model analisis regresi linier berganda dan hasil penelitian menunjukkan bahwa suku bunga SBI berpengaruh positif dan signifikan terhadap IHSG sedangkan kurs dan jumlah uang beredar berpengaruh negatif dan signifikan terhadap IHSG dan tingkat inflasi tidak berpengaruh signifikan terhadap IHSG di BEI.
Embetskjøpmennene i Danmark og Norge på 1600-tallet

Merchant officials in Denmark and Norway in the 17th century
In the 17th century, both foreign trade and taxation grew strongly in Norway. There was a relationship between these two phenomena, and the interaction between them resulted in the creation of a new elite in Norwegian towns. Officials of the Crown had the difficult duty of enforcing steep tax increases, which in fact exceeded the growth in trade. The executors of taxation were the servants of the county governors, namely the bailiffs. Both the governors and the bailiffs came mostly from Denmark. The bailiffs were usually merchants’ sons from Danish provincial towns. In Denmark, merchants in these towns organized trade for the local nobility. Now they did the same in Norway. The largest financial transactions took place in the capital of the monarchy, Copenhagen, in interactions between high-ranking officials and merchants, which generated large fortunes for those who took part in them. What happened in Denmark was reflected in Norwegian towns. The largest concentration of accumulated wealth could be found in the three principal cities: Bergen, Kristiania and Trondheim, but the interaction of Crown revenue and trade was widespread in towns where the county administration was situated as well. In this chapter, the main focus is on the administrative centre of Bratsberg county (now Telemark), Skien. The bailiffs of the county had spectacular careers as merchants and entrepreneurs in the lumber trade. This was based on their relationship to the peasants as tax collectors. The peasants paid the taxes in timber, which the bailiffs processed into different kinds of building materials, mostly in sawmills, producing boards for shipment to England, the Netherlands and other countries. After they resigned as bailiffs, they continued to participate in this trade, in combination with other official functions in the management of the town and the county. Similar career trajectories were pursued in other Norwegian towns during the 17th century. The 18th century witnessed the growing separation of Crown officials from trade.

Edamame is included in perishable products or products that have a fairly short shelf life if post-harvest processing is not carried out. One of the post-harvest processing methods commonly used by the community is drying. The purpose of this study was to analyze the drying process of edamame related to the MLRL and ANN models. This study used a completely randomized design (CRD) with three variations of air velocity, namely 1 m/s, 3 m/s, and 5 m/s. Data collection was repeated three times every 30 minutes until 330 minutes. Multiple linear regression (MLR) model training and validation produce accuracy values of 88.03 and 82.23, and the value of R2 of 0.93 and 0.90. While the training and validation of the artificial neural network (ANN) model resulted in accuracy values of 88.34 and 82.15, and R2 values of 0.93 and 0.90.
