The human immune system plays a pivotal role in protecting the body against pathogens, maintaining homeostasis, and preventing disease. Immunomodulation, the process of regulating immune responses, is crucial for optimal health. In recent years, there has been growing interest in natural remedies for immune system modulation, driven by the recognition of their potential efficacy and safety profiles. This project aims to investigate the immunomodulatory effects of drumstick leaves tablets, derived from Moringa oleifera, a plant known for its rich nutritional and medicinal properties. The study will explore the potential of drumstick leaves tablets to modulate immune responses through in vitro and in vivo experiments. Through comprehensive analysis of the immunomodulatory properties of drumstick leaves tablets, this project aims to contribute to our understanding of natural remedies for immune system modulation. The findings could have significant implications for the development of novel therapeutic interventions aimed at enhancing immune function and improving human health.

M. oleifera is the most adapted tree species in different medicinal eco-systems and has resilience against climate changes. This multiple-use tree provides healthy foods, snacks, honey, and fuel. Besides this, it has immense promising applicationsby offering antimicrobial and antibacterial activities for targeted uses. This validates the court of Hippocrates that let food be the medicine and medicine be the food for which moringa qualifies. In view of this, the antioxidant and in vitro antibacterial potency of the hydro-ethanolic extract of M. oleifera was evaluated on clinically isolated multidrug-resistant strains of Staphylococcus aureus. Furthermore, in vivo, the healing response of M. oleifera extract was analysed on corneal ulcers induced in rabbit eyes infected with methicillin-resistant Staphylococcus aureus. TheM. oleifera extract exhibited exponential antioxidant activity. In-vitro antibacterial activity was evaluated by agar well diffusion assay showing zone of inhibition ranging from 11.05±0.36 to 20±0.40 mm at concentrations of 20, 40, 80, and 160 mg/ml, whereas, in our finding, no zone of inhibition was observed below 20 mg/ml concentration, which indicated that there is threshold limit below which the antibacterial activity of M. oleifera extract is not observed. Furthermore, continuous application of 3% and 5% M. oleifera extract (eye drop) four times a day for 14 consecutive days showed a significant healing response of the eyes of rabbits with corneal ulcers. These results suggest that M. oleifera extract could be a viable alternative to existing antibacterial therapies for corneal ulcers. Additionally, there is a possibility of commercial formulation of M. oleifera extract in the form of deliverable pharmaceutical products; therefore, it should be explored further.

This study aimed to develop a geographical origin discrimination analytical method for chicken breasts and drumsticks based on inductively coupled plasma (ICP). The sixty elements were set as variables, and the geographical origin discrimination analysis was conducted through chemometrics. In orthogonal partial least square discriminant analysis (OPLS-DA), twenty-three variable importance in projection (VIP) elements were selected in chicken breasts, and twenty-eight VIP elements were selected in drumsticks. The importance of the selected elements was displayed by the area under the curve (AUC) value of the receiver operating characteristic (ROC). Verification of OPLS-DA was performed through permutation test and good results were obtained. A heatmap was also used as a method for determining the geographical origin, and each top element discriminant classification was 100 % accurate, as determined through canonical discriminant analysis (CDA). This method shows potential as a food analysis tool and can accurately determine the geographic origin of chicken.

Moringa oleifera is an underutilized perennial tree and is widely cultivated and studied due to its multi-purpose uses. Currently, not much information exists about the rbcL (Ribulose-1,5-bisphosphate carboxylase/oxygenase large subunit) gene sequence in M. oleifera. The rbcL gene is a conserved chloroplast gene and hence can be used for phylogenetic studies of plants at higher and lower taxonomic levels. The data consists of twenty-two rbcL gene sequences, nucleotide, and amino acid compositions of M. oleifera collected from sixteen states across Nigeria. The data offers an understanding of the genetic diversity and evolution of the species, which are crucial for both scientists and breeders working on the crop as well as for attempts to conserve the species.

Though fresh-cut products save our time, but they are very much prone to enzymatic browning that drastically affects product\'s quality and marketability. Drumstick pods are considered as super food due to high nutritional contents. However, the fresh-cut pods are prone to brown discoloration. The enzyme activities promote the softening and cut-surface browning of pods, thus deteriorates their texture, decreases consumer appeal and shortens the shelf life. So, we aimed to assess the effect of citric (1%) and ascorbic (1%) acid treatments on quality attributes of fresh-cut drumsticks at 3-d interval during storage (5 ± 1 °C). In general there was an increase in lignin and quinone contents, while phenolic content was decreased during storage. However, samples subjected to ascorbic acid dip had higher phenolic content, lower rate of lignin formation, and reduced membrane permeability. Enzyme activities (polyphenol oxidase and peroxidase) were found to increase during storage, however, samples treated with ascorbic acid showed lower activities than that of the control and citric acid treated samples. The reduced enzyme activities resulted in the reduced browning incidence and maintained the quality. Therefore, postharvest dip of fresh-cut drumstick in to ascorbic acid (1%) could be suggested to increase the shelf life with reduced browning during low temperature storage.

Drumstick (Moringa oleifera Lam.) is an important vegetable as well as forage crop of arid and semi-arid zones of the tropics. The leaves and pods of the plant are rich sources of minerals and vitamins. In the present work, genetic diversity study of 23 genotypes of M. oleifera collected from Kerala, Tamil Nadu and Karnataka states of India was carried out using seven cytochrome P450 (CytP450) markers. By using seven pairs of CytP450 gene-based markers, 88.25% of polymorphism was recorded among the 23 sampled genotypes. The Polymorphic Information Content (PI), Marker Index (MI) and Resolving Power obtained for seven primers were estimated 0.23, 2.96 and 9.83, respectively. The Unweighted Pair Group Method with Arithmetic mean (UPGMA) dendrogram based on this marker data indicate that genotypes from different geographical regions are placed in the same clusters. The dendrogram and Principal Coordinates Analysis (PCoA) plots derived from the binary data matrices were highly concordant. The investigation, in brief, proved that CytP450 based marker system is efficient in the elucidation of genetic diversity in M. oleifera accessions.

BACKGROUND: Moringa oleifera (MO) kernel oil is categorized as a high-oleic oil that resembles olive oil. However, unlike olive trees, MO trees are largely present in most subtropical and tropical countries. In these countries, therefore, the benefits of oleic acid can be obtained at a cheaper price through the consumption of MO kernel oil. This study reports on the effect of different extraction methods on oxidative properties of MO kernel oil during storage for 140 days at 13, 25, and 37 °C.
RESULTS: All aqueous enzymatic extraction (AEE)-based methods generally resulted in oil with better oxidative properties and higher tocopherol retention than the use of solvent. Prior to AEE, boiling pre-treatment deactivated the hydrolytic enzymes and preserved the oil\'s quality. In contrast, high-pressure processing (HPP) pre-treatment accelerated hydrolytic reaction and resulted in an increase in free fatty acids after 140 days at all temperatures. No significant changes were detected in the oils\' iodine values and fatty acid composition. The tocopherol content decreased significantly at both 13 and 25 °C after 60 days in the oil from SE method, and after 120 days in oils from AEE-based methods.
CONCLUSIONS: These findings are significant in highlighting the extraction methods resulting in crude MO kernel oil with greatest oxidative stability in the storage conditions tested. Subsequently, the suitable storage condition of the oil prior to refining can be determined. Further studies are recommended in determining the suitable refining processes and parameters for the MO kernel oil prior to application in variety food products. © 2019 Society of Chemical Industry.

WRKY proteins belong to one of the largest families of transcription factors. They have important functions in plant growth and development, signal transduction and stress responses. However, little information is available regarding the WRKY family in drumstick (Moringa oleifera Lam.). In the present study, we identified 54 MoWRKY genes in this species using genomic data. On the basis of structural features of the proteins they encode, the MoWRKY genes were classified into three main groups, with the second group being further divided into five subgroups. Phylogenetic trees constructed from the sequences of WRKY domains and overall amino acid compositions derived from drumstick and Arabidopsis were similar; the results indicated that the WRKY domain was the main evolutionary unit of WRKY genes. Gene structure and conserved motif analysis showed that genes with similar structures and proteins with similar motif compositions were usually clustered in the same class. Selective pressure analysis indicated that although neutral evolution and positive selection have happened in several MoWRKY genes, most have evolved under strong purifying selection. Moreover, different subgroups had evolved at different rates. The levels of expression of MoWRKY genes in response to five different abiotic stresses (salt, heat, drought, H2O2, cold) were evaluated by reverse transcription polymerase chain reaction (RT-PCR) and quantitative RT-PCR (qRT-PCR), with the results indicating that these genes had different expression levels and that some may be involved in abiotic stress responses. Our results will provide a foundation for cloning genes with specific functions for use in further research and applications.

The drumstick tree has traditionally been used as foodstuff and fodder in several countries. Due to its high nutritional value and good biomass production, interest in this plant has increased in recent years. It has therefore become important to rapidly and accurately evaluate drumstick quality. In this study, we addressed the optimization of Near-infrared spectroscopy (NIRS) to analyze crude protein, crude fat, crude fiber, iron (Fe), and potassium (K) in a variety of drumstick accessions (N = 111) representing different populations, cultivation programs, and climates. Partial least-squares regression with internal cross-validation was used to evaluate the models and identify possible spectral outliers. The calibration statistics for these fodder-related chemical components suggest that NIRS can predict these parameters in a wide range of drumstick types with high accuracy. The NIRS calibration models developed in this study will be useful in predicting drumstick forage quality for these five quality parameters.
