Dyes are stable organic pollutants that have been used in many industries and become one of the toxic contaminants for the environment. This research aimed at preparing a magnetic chitosan nanocomposite (MCN) as an effective adsorbent for cationic and anionic dye removal from aqueous solution. The MCN was synthesized using a coprecipitation method. The physical properties of MCN were characterized using elemental analysis (CHNO), vibrating sample magnetometry (VSM), scanning electron microscopy (SEM), thermogravimetric analysis (TGA) and X-ray diffractometry (XRD). The results confirm that chitosan has been embedded on the surface of magnetic material and shows superparamagnetic properties behavior. A series of adsorption were conducted to investigate dosage of adsorbent, contact time and initial dye concentration to obtain the optimum condition of adsorption for both methylene blue (MB) and congo red (CR) dyes. The experimental equilibrium adsorption were then analyzed by the Langmuir and Freundlich isotherm models. Based on the correlation coefficient (R 2) values, the equilibrium adsorption data were fitted to the Langmuir isotherm model. The maximum adsorption capacity (q m) obtained from the Langmuir isotherm model for MB and CR onto MCN was 0.1308 and 1.8257 mg/g, respectively. Results highlight the potential of MCN application as an adsorbent for water contaminated by dyes.

This paper reviews the quality changes that occur towards the food products during the frozen storage period. This research aims to determine the significant physical and chemical changes that had occurred onto the frozen foods. Indeed, refrigerated storage is the easiest way to preserve food within short handling time. Based on the observation, it was discovered that the kinetics reactions help to establish computer-aided quality, prediction models. In certain food products, the negative impact of temperature indicated the need for a thorough evaluation of the quality parameters of individual's kinetics reaction. In general, a reasonable temperature to store food is-18 °C for most frozen foods, and this will retain the quality of commercial storage.

The present work aimed to review ten species of Ficus which is belong to the Moraceae family.  In total, 36 articles were reviewed by using the online search engine PubMed, Scopus, Google Scholar, and Web of Science.  Ten species of Ficus were searched for phytochemicals documentation, which resulted in 250 secondary metabolites and 400 different compounds. Alkaloids compounds such as liriodenine and lysicamine, terpenes, steroids, and flavonoids were found to have anticancer, antibacterial, antifungal, and other biological activities.  Most Ficus species contain secondary metabolites compounds with different types of application. This mini-review provides insights on Ficus’s phytochemical compounds and their importance as medicinal properties.

This study was planned to investigate the probable protective role of Salvia officinalis have in the nanoparticles and aqueous extracts on female rats which exposed to Bisphenol A. At the end of the experiment the blood samples were collected by heart puncture to evaluate the RBC and WBC count, Hemoglobin, Platelets as well as follicle stimulating hormone (FSH), luteinizing hormones (LH), estrogen, creatinin, urea, aspartate aminotransferase, alanine amino transferees and alkaline phosphatase were estimated furthermore after the rats were scarified Liver, Kidney, Uterus and ovary were collected for histological study. The result shows significant decrease in the RBC, PLT and Hb count in the BPA group in comparison with the control and SOSNPs and SOE groups. In addition, there is a significant increase in WBC count and estrogen level in the BPA treated rats in comparison with control, SOSNP and SOE treated rats. As well as, there is significant increase in the liver enzymes (AST, ALP and ALP) in the BPA treated rats in comparison with control and SOSNP & BPA treated groups. Histological studies show presence of vacuolation with absence of radial arrangement in the hepatocytes in the liver of rats. The histological studies for the uterus of rats Beside ovarian sections BPA reveled mature follicle without oocyte with cyst like structure in the ovary in comparison with control group, these effects were relieved by the role of SOSNP and SOE in alleviating the effects of BPA on studied parameters.

The primary objective of this study is to evaluate the seed extracts from agro waste to examine the effectiveness of antimicrobial. Therefore, by using the disc diffusion assay, the antibacterial activity was evaluated along with two medically important bacterial pathogens such as methicillin resistant Staphylococcus aureus (S. aureus) (MRSA) and Escherichia coli (E. coli) in the seed extracts of Cucurbita sp., Carica papaya L., Nephelium lappaceum, Mangifera indica, Durio zibethius and Artocarpus heterphyllus Lam seeds. Seed extracts of agro waste were analyzed for the phytochemical constituents. Analysis of the qualitative phytochemical indicated the importance of phytochemical compounds for instance glycosides, saponins, flavanoids, tannins and alkaloids. Variations had been seen in the inhibition zone depending on the species and different seed extracts concentrations used for bacteria, the highest inhibition zone observed for M. indica and C. papaya L. The obtained data of this study presented greater insights which allow the use of seed extracts that were obtained from the agro-waster, to be used as raw materials for food, chemical, and pharmaceutical industries.
