Effect of moringa oleifera with pure and Zn-doped Mn and Ni nanoferrites for hyperthermia applications

Nanoferrites like spinel manganese ferrite (MnFe2O4) and inverse spinel nickel ferrite (NiFe2O4) have an efficient heating deportment to the destruction of neoplasm. The incorporation of Moringa oleifera (MO) leaf extracts with magnetic nanoparticles as heat mediators is an effective approach for treating magnetic hyperthermia. This study investigated the potential heating behavior of bare, Zn-doped MnFe2O4 and NiFe2O4 nanoparticles (NPs) with Moringa oleifera leaf extracts as magnetic hyperthermia agents. High-resolution transmission electron microscopy showed the spherical-like morphology of MnFe2O4 NPs with no impurities in the EDX spectra. X-ray diffraction spectra confirmed the cubic spinel and inverse spinel structure for MnFe2O4 and NiFe2O4 NPs, respectively. Magnetic properties of the prepared nanoferrites exhibit low coercivity values (in the range of 13–18 Oe representing superparamagnetic behavior. Further, the binding energies of the prepared nanoferrites were revealed by X-ray photoelectron spectroscopy. The effective magnetic anisotropy constant (Keff) was calculated to be around 3.9–5.9 kJ/m3 by electron spin resonance. An increased specific surface area (120.69 m2/g) and wider porosity (17.053 nm) were observed for MnFe2O4/MO NPs through Brunauer-Emmett-Teller (BET) analysis. Thermal properties were investigated by measuring the effective specific absorption rate in an alternating magnetic field ranging from 23 to 31 * 10−9 W/g Oe2 Hz. Results indicated that the green synthesized MnFe2O4/MO NPs are promising agents for magnetic hyperthermia applications in cancer therapy.

Synthesized Gold Nanoparticles with Moringa Oleifera leaf Extract Induce Mitotic Arrest (G2/M phase) and Apoptosis in Dalton's Lymphoma Cells.

The therapeutic potential of chemically synthesized AuNPs has been demonstrated in various types of cancer. However, gold nanoparticles (AuNPs) synthesized using typical chemical methods have concerns regarding their environmental safety and adverse impact on human well-being. To overcome this issue, we used an environmentally friendly approach in which gold nanoparticles were synthesized using Moringa oleifera leaf extract (MLE). The present research was mainly focused on the biosynthesis and characterization of gold nanoparticles (AuNPs) using Moringa oleifera leaf extract (MLE-AuNPs) and explore its anticancer potential against Dalton's Lymphoma (DL) cells. Characterization of the MLE-AuNPs was conducted using UV-Vis Spectroscopy to confirm the reduction process, FTIR analysis to ascertain the presence of functional groups, and XRD analysis to confirm the crystallinity. SEM and TEM images were used to examine size and morphology. After characterization, MLE-AuNPs were evaluated for their cytotoxic effects on Dalton's lymphoma cells, and the results showed an IC50 value of 75 ± 2.31 µg/mL; however, there was no discernible cytotoxicity towards normal murine thymocytes. Furthermore, flow cytometric analysis revealed G2/M phase cell cycle arrest mediated by the downregulation of cyclin B1 and Cdc2 and upregulation of p21. Additionally, apoptosis induction was evidenced by Annexin V Staining, accompanied by modulation of apoptosis-related genes including decreased Bcl-2 expression and increased expression of Bax, Cyt-c, and Caspase-3 at both the mRNA and protein levels. Collectively, our findings underscore the promising anti-cancer properties of MLE-AuNPs, advocating their potential as a novel therapeutic avenue for Dalton's lymphoma.

Evaluation of Moringa Oleifera Leaf Extract for its In vitro Antibacterial Properties, Mechanism of Action, and In vivo Corneal Ulcer Healing Effects in Rabbits' Eyes.

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.

Synergism of Anti-Malarial Effect of Carica papaya L. and Moringa oleifera Leaf Extracts in Mice

Malaria parasites, Plasmodium spp, can develop resistance to anti-malarial drugs. Hence, potential alternative therapeutic agents should be explored. This research aimed to investigate the anti-malarial effect of a combination of Carica papaya and Moringa oleifera leaf extract. Peter’s test performed on Balb/c mice to investigate the malarial parasite growth inhibition. Mice were infected with Plasmodium berghei by intraperitoneal injection to provoke rodent malaria. After infection, we grouped every 5-6 mice into different treatment groups, including a negative control group, a positive control group treated with artesunate, a moringa group, a papaya group, and a combination therapy group. Treatments were initiated 3 hours after infection (day 0) and continued every day until day 3. On day 4, we examined a thin smear of the tail vein blood for parasitemia to calculate the suppression rate. The result shows that the parasite suppression rate of C. papaya leaf extract (CPLE) is 15.02 % (percent parasitemia 4.56±1.96), the suppression rate of M. oleifera leaf extract (MOLE) is 17.32% (percent parasitemia 4.44±1.78) and that of the combination extract (CE) is 28.73% (percent parasitemia 3.82±1.48).  In conclusion, there is a synergism of the anti-malarial effect of the combined leaf extract of C. papaya and M. oleifera.

Data analysis on body weight and feed intake used the SPSS ANOVA test and paired T-test. The results of the paired T-test (p<0.05) showed that Moringa oleifera leaf extract and glucomannan (Amorphophallus muelleri Blume.) significantly reduced body weight and feed intake. In conclusion, administration of Moringa oleifera leaf extract and glucomannan (Amorphophallus muelleri Blume.) in group K4 (80 mg/kgBW Moringa oleifera leaf extract: 120 mg/kgBW glucomannan Amorphophallus muelleri Blume) can reduce feed intake (4.29 g) and body weight (36.67 g) effectively.

The Effect of Moringa Leaf Extract (Moringa oleifera) in Drinking Water on Broiler Chicken Carcass Production

The research was carried out in the chicken house of the Faculty of Animal Husbandry, Marine and Fisheries, Nusa Cendana University, Kupang from April 7th 2023 to May 26th 2023. The aim of this research was to examine the effect of administering Moringa oleifera leaf extract in drinking water on broiler chicken carcass production. This research used 96 DOC broiler chickens of the CP 707 strain. The experimental design used was a Completely Randomized Design (CRD) with 4 treatments and 6 replications, each replication consisting of 4 broiler chickens. The treatments given were P0= drinking water without moringa leaf extract (control), P1= 40 ml moringa leaf extract/l drinking water, P2= 80 ml moringa leaf extract/l drinking water, P3= 120 ml moringa leaf extract/l drinking water. The variables studied were final body weight, carcass percentage, non-carcass percentage and abdominal fat. The results of statistical analysis show that moringa leaf extract at levels of 0, 40, 80 and 120 ml/l of drinking water did not have a significant effect (P>0.05) on final body weight, percentage of carcass and non-carcass percentage of broiler chickens, but increased the percentage of abdominal fat significantly (P<0.05). Based on the research results, it can be concluded that the use of Moringa oleifera leaf in drinking water up to a level of 120ml/l drinking water can increase the percentage of abdominal fat but did not change the final body weight, carcass percentage and non-carcass percentage of broiler chickens.

Histopathological examination of the skin, liver and kidney were done at the end of 7 weeks. Results: There was reduction in tumor size in the Moringa Oleifera pod and leaf extract treated groups. Histopathology revealed infiltration of the cells with scarring of epidermis in the extract treated groups indicating the healing of tissues more pronounced at higher concentration. Control group showed atypical squamous cells whereas the standard drug treated group showed infiltration and scarring. Conclusion: This study exhibits a dose dependent anticancer effect of Moringa oleifera pod and leaf extracts in mice which was comparable with the standard drug 5-Fluorouracil.

Effect of Moringa oleifera Leaf Extract on the Growth Performance, Hematology, Innate Immunity, and Disease Resistance of Nile Tilapia (Oreochromis niloticus) against Streptococcus agalactiae Biotype 2.

The present study aimed to investigate the effects of Moringa oleifera leaf (MLE) extract-supplemented diets on the growth, feed utilization, hematology, innate immune response, and disease resistance of Nile tilapia against Streptococcus agalactiae Biotype 2. Four hundred and fifty Nile tilapia (32.61 ± 0.2 g/fish) were randomly allocated into fifteen tanks (30 fish/tank). Different concentrations of MLE at 0%, 0.5%, 1%, 1.5%, and 2% were fed to the Nile tilapia for 30 days, and the growth, feed utilization, hematology, and innate immune response of the Nile tilapia were determined. After the feeding trial, the Nile tilapia were challenged with a S. agalactiae Biotype 2 infection, and the relative percentage of survival (RPS) was determined. Results revealed the presence of quercetin, kaempferol, and p-coumaric acid in the MLE extract, exhibiting stronger antimicrobial activity against S. agalactiae Biotype 2. The diets supplemented with the MLE-0.5 group showed a significantly higher growth, feed utilization, hematology, and innate immune response in the Nile tilapia compared to the control and other MLE groups. Additionally, the MLE-0.5 group exhibited a significantly higher RPS of the Nile tilapia against S. agalactiae Biotype 2. Therefore, MLE-0.5 can be employed as an alternative feed supplement in sustainable Nile tilapia farming to protect against S. agalactiae Biotype 2.

Efficacy of moringa (Moringa oleifera) formulations on suppression of root-knot nematodes (Meloidogyne incognita) and growth of tomato (Solanum lycopersicum)

Root-knot (Meloidogyne sp.) nematodes are among the most important causes of reduced tomato (Solanum lycopersicum) yield. Therefore, an investigation was conducted in 2022 at the Aquaculture Research Unit lab to evaluate the effectiveness of moringa (Moringa oleifera) leaf extract application in controlling root-knot nematode in tomatoes. During a survey of a tomato field, M. incognita was identified from the rhizosphere soil samples. Fresh leaf extracts of moringa, including positive control (fenamiphos 0.06), were investigated in vivo for efficacy against M. incognita in root and soil. Seedlings of tomato were inoculated with 3000 eggs and second-stage juveniles (J2s) of M. incognita in pot trials, with treatments comprising fresh leaf extracts of moringa in a series of concentrations (40 ppm-80 ppm). Fifty-six days after inoculation, the phytonematicide had reduced eggs and J2s in soil by 65-90%, gall number by 45-87%, and gall index by 35-82%. The best treatment was moringa leaf extract (80 ppm), which was significantly different (P less than 0.05) from moringa leaf extract at 60 ppm and 40 ppm (P less than 0.05). However, fenamiphos had no significant difference (P greater than 0.05). The results showed moringa leaf extract (80 ppm) was the best treatment for controlling root-knot nematode in tomatoes.

GC–MS analysis of Moringa oleifera leaf extract and effects of administration on histology of reproductive organs and liver of female rats exposed to chronic unpredictable stress

Exposure to several stressors and other lifestyle factors converge to affect the chemistry, structure, and function of body tissues over time. Chronic unpredictable stress (CUS) protocol has been widely used to study the impact of stress exposure in several animal models. Moringa oleifera leaf extract (MOLE) is known to have hepatoprotective and antioxidant properties. The study aimed to determine the effect of the administration of MOLE during conditions of chronic stress on the histology of reproductive organs, heart and liver. Twenty mature inbred healthy virgin female Wistar rats were randomly placed into four groups of five rats per group as follows: Group One (water and normal rat chow ad libitum), Group Two (CUS protocol only), Group Three (CUS protocol + 200 mg/kg MOLE), Group Four (CUS protocol + 300 mg/kg of MOLE). CUS protocol was applied unpredictably for two weeks. The chromatogram of the GC–MS analysis indicated the presence of 41 compounds. Photomicrograph examination of the uterus, ovaries, and liver showed severe alterations in the histology of the tissues. Consumption of MOLE during chronic stress has shown deleterious effects and is not advised for consumption during stress conditions.

Green route to prepare zinc oxide nanoparticles using Moringa oleifera leaf extracts and their structural, optical and impedance spectral properties

This article investigates biosynthesis of zinc oxide (ZnO) nanoparticles (NPs) from Moringa oleifera leaves extract using an eco-friendly preparation method. The crystalline structure, optical properties, morphology and impedance characteristics of ZnO NPs were analyzed using impedance spectroscopy, powder X-ray diffraction (XRD), scanning electron microscopy, Fourier transform infrared spectroscopy (FTIR) and ultraviolet spectroscopy (UV-vis). The powder XRD pattern confirmed the crystallinity of the prepared samples as well as enabled determining their crystallite size and pure phase portion. The FTIR study confirmed the presence of functional groups responsible for reduction metal ions into ZnO NPs. UV-vis absorption spectra contained the absorption peak corresponding to ZnO NPs. Impedance spectroscopy of the prepared ZnO NPs revealed the grain boundaries in them and confirmed their semiconducting nature.

Efficiency of green synthesised carbon nanotubes from Moringa oleifera leaf extract as potential toxic metals adsorbent in polluted water

Abstract Among the many drawbacks of the current wastewater treatment systems are their high energy consumption and creation of harmful sludge. Carbon nanotubes (CNTs) are advantageous for the treatment of water due to their strong adsorption capacity and selectivity towards various pollutants. Thus, creating methods for treating water by producing CNTs from Moringa oleifera leaf extract can greatly help with the clean water problem. The synthesised material’s Ultra Visible (260–385 nm), FTIR (764–3295 cm−1) and Scanning Electron Microscope (SEM) characterizations have demonstrated their CNTs characteristics. The repeatability testing yielded the %RSD values for Ca = 0.4, Cu = 0.24, Mg = 0.9, Pb = 1.06 and Zn = 0.36 which suggest that the AES approach demonstrated a high degree of precision. The findings show that the quantity of recovered metals increases with retention period. Mg > Cu > Zn > Ca > Pb was the order of the metal adsorption capacity throughout retention durations of 3, 6, 24, and 48 h. As the initial concentrations of the components under research were doubled and tripled, so were the removal capacities of CNTs increased which may be as a result of an increase in metal ions in the solution. The outcomes show how well the synthetic CNTs can remove heavy metals from wastewater.

We report magnetically-separable, reusable, green-synthesized Fe3O4/rGO/ZnO, as heterogeneous catalyst for photo-Fenton degradation of organic pollutants in aqueous solution under certain treatments. Fe3O4 nanoparticles was green-synthesized using Moringa oleifera leaf extract, while rGO was synthesized utilizing Amaranthus viridis leaf extract. Fe3O4/rGO was composited under sonication treatment. Afterwards, Fe3O4/rGO was doped with ZnO with various concentration of ZnO. X-ray diffraction and selected area electron diffraction showed that Fe3O4 and ZnO had spinel cubic and hexagonal structure, respectively; another phase appeared as Fe2O3 spinel cubic structure. Crystallite size was decreased as the ZnO concentration increased. Morphology image showed almost spherical, non-uniform, and slightly dispersed particle under agglomerated condition, attaching to rGO sheets. The particle size of Fe3O4, Fe3O4/rGO, and Fe3O4/rGO/ZnO is 14.3; 14.1; and 10.4 nm, respectively. Fourier-transform infrared spectra showed metallic functional groups, such as Fe-O and Zn–O at 562–589 and 462–478 cm−1 also suggests nanocomposite formation. However, blue-shift absorption and band gap widening were observed with ZnO addition. Raman spectroscopy revealed the formation as-synthesized GO and rGO. Vibrating sample magnetometer showed that green-synthesized Fe3O4/rGO/ZnO exhibited superparamagnetic properties. Removal efficiency of photodegradation methylene blue was optimal for green-synthesized Fe3O4/rGO/ZnO under sonication treatment, reached 100 % degradation within 180 min for uptake every 30 min. Photodegradation was also analyzed using Langmuir-Hinshelwood kinetic model, resulting rate constant of 24.7 × 10−3 min−1 and half-life time of 28.1 min at optimum treatment. Reusability of photocatalytic activity after 3 cycles showed only a tiny drop in catalytic efficiency. Meanwhile, it possesses high stability in catalytic activity and structure. The green-synthesized Fe3O4/rGO/ZnO potential as an environmentally friendly reusable photocatalyst for wastewater degradation.

Objective: To investigate the effect of Moringa oleifera leaf extract on semen quality parameters in Teressa goat buck. Methods: A total of 25 semen samples from six bucks were selected for the study. Spermatozoa of 150× 106 were incubated in 0, 300, 500 and 700 μg of leaf extract as group I, II, III and IV, respectively. Liquid stored semen samples were analysed for motility, viability, total sperm abnormalities, plasma membrane, acrosomal and nuclear integrities, seminal plasma intracellular enzymes [aspartate aminotransferase (AST), alanine aminotransferase (ALT) and lactate dehydrogenase (LDH)] and total antioxidant capacity (TAC) and spermatozoa malondialdehyde (MDA) and cholesterol efflux in comparison with the control group (group I) for up to 72 h. Results: Moringa oleifera leaf extract (500 μg/150× 106 spermatozoa)-treated semen had significantly higher motility, viability, plasma membrane, acrosomal and nuclear integrities, and TAC (P<0.05), and had significantly lower total sperm abnormalities, AST, ALT, LDH, MDA production and cholesterol efflux compared to those in other Moringa oleifera leaf extract treated (300 or 700 μg/150×106 spermatozoa) and control groups at different hours of liquid storage (P<0.05). Semen quality parameters and TAC showed an increasing trend and total sperm abnormalities, MDA production, leakage of intra-cellular enzymes and cholesterol efflux showed a decreasing trend from group I to group III and then an opposite trend from group II to group IV at different hours of liquid storage. Conclusions: Moringa oleifera leaf extract 500 μg/150×106 spermatozoa can be used for liquid semen preservation in Teressa goat at Andaman and Nicobar Islands.

Microstructures and Dielectric Permittivity Properties of Fe3O4/Cdots Nanocomposites Synthesized by Green Route Utilizing Moringa Oleifera Extract and Watermelon Peel

Dielectric materials are beneficial for storing electrical energy due to their insulating and polarization properties in response to external electric fields. Magnetite has shown promise as a dielectric material among other materials due to its good magnetic properties, low toxicity, and biocompatibility. However, the weakness of Fe3O4, which has low stability and easy agglomeration, requires a modification on its surface by using Carbon dots (Cdots). This research investigates the dielectric properties of Fe3O4/Cdots obtained through the green synthesis method. Fe3O4 nanoparticles were synthesized using the co-precipitation method with Moringa oleifera leaf extract as a reducing and stabilizing agent. In contrast, Cdots were synthesized using the hydrothermal method with watermelon peel waste as a carbon source. The Fe3O4 composite nanoparticles were characterized using X-ray diffraction (XRD), scanning electron microscopy-energy dispersive X-ray (SEM-EDX), ultraviolet-visible spectroscopy (UV-Vis), and impedance spectroscopy. The XRD spectra revealed the existence of cubic inverse spinel and a reduction in crystal size as the concentration of Cdots increased, measuring 7.8 and 7.1 nm, respectively. SEM-EDX revealed that the sample is composed of Fe, O, and C elements and has a spherical shape with Cdots distributed on the surface of Fe3O4. The UV-Vis spectrum showed the absorption peak of Cdots at 282 nm. The Fe3O4 absorption peak is identical to the Fe3O4/Cdots absorption peak at 193 nm. The increase in band gap energy from 2.96 to 3.33 eV is related to the increase in Cdots concentration. In the 10-900 kHz frequency range, dielectric property tests demonstrated peak dielectric permittivity values (real and imaginary). A substantial decrease was observed between 10 kHz and 200 kHz, followed by a relatively stable pattern up to 900 kHz. The loss tangent value obtained has a tanδ value <0.5, which means that the addition of Cdots affects reducing the energy loss stored in Fe3O4.

The effectiveness of Moringa oleifera in the preservation of periodontium after radiation therapy: An experimental animal study

BackgroundRadiation therapy produces reactive oxygen species, which have been linked to various degenerative conditions in periodontal attachment. This study aimed to assess the beneficial effects of aqueous Moringa oleifera leaf extract on the periodontium of albino rats exposed to fractionated gamma radiation. Materials and methodsThis experimental study involved 24 adult male albino rats divided into three groups: Group M received M. oleifera leaf extract (300 mg/kg) intraperitoneally for 14 days; Group R received 20 Gy fractionated gamma irradiation; and Group MR received the same M. oleifera regimen as Group M and then fractionated gamma irradiation dose as Group R. On the first and seventh days post-radiation, bone, cementum, and periodontal ligament samples were histologically and histomorphometrically examined. ResultsThe periodontal ligament, alveolar bone, and cementum showed structural damage in Group R. A relative persistence of normal periodontal tissue structures was seen in Group MR, showing less disruption of the periodontal ligament and greater trabecular bone thickness than Group R. The histomorphometric analysis showed that the mean periodontal ligament width was highest in Group R7 (245.20 μm) and lowest in Group M7 (54.55 μm). In addition, the mean cementum width was highest in Group R1 (88.99 μm) and lowest in Group M1R1 (17.87 μm) and differed significantly between groups. ConclusionWithin the limitations of this study, Moringa oleifera leaf aqueous extract showed the potential to reduce the adverse effects of radiation, control inflammation, and support tissue healing in a rat model.
