After seven days of the administration, four animals from each of the groups were sacrificed and the rest were sacrificed after fourteen days, and biochemical alterations were monitored. The effects after the seven-day administration revealed that there was no significant (p > 0.05) difference in organ-body weight percentage, liver functional indices, kidney functional indices and the activity of some cytosolic and membrane-bound enzymes studied but following the fourteen-day administration, a significant difference (p < 0.05) were observed with increase in organ-body weight percentage of selected organs, increase in serum activity of the enzymes: ALT, AST, ALP; and aberrant variation in the kidney functional indices studied at the 50, 75 and 100 mg/kg body weight showing selective toxicity of the extract. Inconclusive results were obtained in the analysis of the seminal parameters for both the seven- and fourteen-day administration while similar effects on hematological parameters were observed for both the sevenand fourteen-day administration.

Several previous reports performed antibacterial screening activities involving natural herbs and synthetic drugs. Alanine racemase and transglycosylase are essential proteins for peptidoglycan membrane synthesis in bacteria and an alternative target for antibacterial performance. This study identified six flavonoid compounds in Syzygium myrtifolium to perform the antibacterial activity. In silico study was conducted for modelling flavonoids – protein complexes. Five flavonoids from S. myrtifolium were taken out of the canonical smiles from the PubChem database and modelled three-dimensional structure using ChemDraw and molView. Targeted protein, alanine racemase and transglycosylase were downloaded from Protein Data Bank with ID 4WR3 and 1SLY. Ligands and proteins were interacted by Molegro virtual Docker 5.0 and visualized by Discovery studio version 21.1.1. Five flavonoids showed inhibition with alanine racemase and transglycosylase in the same active sites of control and sodium benzoate. According to the binding energy, calopiptin performed the lowest binding energy value in alanine racemase complexes, while 2-Propanone, 1,3-bis(5-nitro-2-furanyl) showed the lowest value of four other flavonoids at transglycosylase complexes. The type of interactions were electrostatic, hydrogen bonds, hydrophobic interactions and unfavorable ones. Low binding energy and varied interaction types indicated tight of ligand-protein interaction. In summary, five flavonoids inhibited alanine racemase and transglycosylase, and the peptidoglycane membrane synthesis in bacteria might be inferred.

Young fruits are harvested at a time when the seed coats have been established, but cotyledons have not yet formed. This study covered morphological characteristics, growth behavior, and cultivation practices suitable for increasing the production of the ridge gourd in urban ecosystems. Results of observation revealed the heart-shaped leaf of the ridge gourd was very uniform, and the leaf surface was flat so that their leaf area could be accurately estimated using leaf length and/or width (R2 > 0.97). Yet, leaf thickness was not a reliable predictor for the leaf area (R2 < 0.34). The length of petioles was not correlated with the leaf blade area. All single leaves, multiple tendrils, an inflorescence of male flowers and/or a single female flower, and a branch could be formed at each stem node. Water content in the leaf blade was lower than in the petiole. This phenomenon is related to water favor loss due to transpiration activity. Nevertheless, the total conserved water within the leaf blade was 6.26 times more than those within the petiole. The process of fruit enlargement followed the Sigmoid curve. The upper end of the curve started to flatten 10 days after the female flower bloomed. Moreover, at the age of 10 days, cotyledon has not yet formed, so it can be used as a guide to determine the harvest time of the gourd ridge fruit. Based on the leaf SPAD value, by the time the fruit began to enlarge, 4-5 leaves at the stem base were instigated to show symptoms of senescence. Ridge gourd fruit fresh weight can be best estimated using the length × diameter of the plants as a predictor.

Fish meal continues to be a major source of protein in fish feed production. But its supply cannot keep pace with everexpanding aquaculture production, leading to its high cost. Plants are being considered as potential replacements in the search for new alternatives to fish meals. But their application depends significantly on their digestibility in target species. The present study aims to determine the protein content of four locally available plants Moringa oleifera, Ipomoea aquatica, Lemna minor and Salvinia natans, and test their digestibility in vitro by using the pH drop method in two important food fish Anabas testudineus and Channa punctata, of Assam, India. The crude protein in all plants ranged from 19-29%, and the highest crude protein was observed in Lemna minor (29.9 ± 2.34%). The in vitro digestibility was estimated by calculating the RPD% (relative protein digestibility) using casein as a standard reference. Digestibility of the plant proteins exhibited species-specific variations. The RPD% ranged from 50.39% to 75.39% in A. testudineus, and 41.38% to 54.02% in C. punctata compared to that of casein (100%). The highest RPD% was observed in I. aquatica (75.39%) for A. testudineus, and the lowest (50.39%) in L. minor whereas, in C. punctata, the highest RPD% was observed in L. minor (54.02%) and the lowest in I. aquatica (41.38%). The digestibility of all plant proteins was comparatively higher in A. testudineus than in C. punctata. Our results indicate that I. aquatica and L. minor may be a suitable replacement for animal protein in the diet of A. testudineus and C. punctata, respectively, because of their good protein content and high digestibility. Moringa may be considered for utilization in the fish feed as it recorded good protein and digestibility. This information may be useful in developing a cost-effective, plant-based protein diet for the two fish species for their mass production.

These pests can develop into a variety of disease vectors, causing damage to chicken coops, decreased chick performance, and financial losses to farmers. In Indonesia, synthetic insecticides are still used for pest control, which is detrimental to non-target creatures and the environment. The purpose of this study is to analyze the effectiveness of biopesticides from cinnamon bark extract (Cinnamomum aromaticum), nutmeg seeds (Myristica fragrans), lavender flowers (Lavandula angustifolia), and lime peel (Citrus aurantifolia), as well as synthetic insecticides alpha-cypermethrin against A. diaperinus larvae and imago. Bioinsecticide levels are 2.5%, 5%, 7.5%, and 10%, while alpha-cypermethrin levels are 1%, 4%, 7%, and 10%, respectively, based on LC50 values. The analysis was repeated three times and the treatment was carried out every two days for a total of 14 days. The data were analyzed with paired sample t-tests to determine the average difference in each treatment when there was an average difference and calculated N-Gain score to determine the effectiveness of biopesticides and synthetic insecticides. The average value of N-Gain essential oil from cinnamon bark extract was successful in causing A.diaperinus death in the imago stage (81.14) and the highest larvae (80) of other test solutions. Cinnamon bark extract and nutmeg seed extract are effective in imago (95.14) and larvae (78.91), respectively, and can be used as a natural biopesticide to replace synthetic insecticides in the control of A.diaperinus in imago and larvae stages.

The plot method (20x20 m and 1x1 m dimension) was carried out to observe seedling, sapling, and tree (seedling h = 0-1.5 m, sapling h ≥ 1.5 m, tree D > 20 cm). The trees' species name, distance, number, and DBH were collected. Arthropods were sampled using PFT and SN methods. A vial (d=5 cm) was used for PFT, and SN was applied at a distance of 1x10 meters with 3 repetitions. Plants with the role of weeds in monoculture dominate (TA=45). Drosophilidae is the most recorded family in monoculture. Polyculture and agroforestry systems increased the diversity of arthropods in the vegetation, and Formicidae predominated by PFT (TA=28% and 81%, respectively). PCA shows the role of detrivores is mostly found in agroforestry, and herbivores dominate the monoculture.

Stevia has been shown to be safe for human consumption and has been utilised as a sweetener substitute for diabetic and obese people. In this study, the structure and gene content involved in the synthesis of putative UDP-glycosyltransferase 76G1 (UGT76G1) protein in S. rebaudiana MS007 were analysed using an in-silico method. Homologous search using BlastP revealed the highest percentage of identity, score, and E-value for UDP-glycosyltransferase 76G1-like of Helianthus annuus (ID: XP_021973845.1). The presence of IPR002213 UDP-glucuronosyl/UDP-glucosyltransferase entry, which is available at locations 89bp to 246 bp, was also verified by the protein family search using InterPro. MEGA-X software was used to construct a molecular phylogeny study, revealing that this protein belongs to the Asteraceae family. To predict the primary, secondary, and tertiary protein structures of the putative UGT76G1 protein, the ProtParam, ExPasy, PSIPRED, and Phyre2 programmes were implemented. The putative UGT76G1 protein’s tertiary structure prediction was given a score of 100.0% confidence by the single highest scoring template and a coverage of 98%, with the dimension of the model being (Å) of X: 52.453, Y: 61.270, and Z: 48.102. The UGT76G1 model fulfilled the quality standards and was approved for further analysis after validation performed by PROCHECK, VERIFY3D, and ERRAT. Thus, the findings of this work have contributed to a better knowledge of putative UDP-glycosyltransferase 76G1 features and target recognition processes, which will lead to better information on protein-protein interaction in S. rebaudiana MS007.
