Phyto-mediated biosynthesis of silver nanoparticles using Aloe barbadensis Miller leaves gel with improved antibacterial, anti-fungal, antioxidant, anti-inflammatory, anti-diabetic, and anti-cancer activities

An effective topical therapeutic agent requires a multifunctional attribute such as antibacterial, antioxidant, and anti-inflammatory efficacy. The green-synthesized metallic and metallic oxide nanoparticles have shown significant applicability in this regard. Hence a biosynthesis of silver nanoparticles (AgNPs) using Aloe barbadensis miller leaf gel was fabricated and evaluated for effect of imperative influences such as temperature, time, and concentration of reactant on AgNPs synthesis. Furthermore, the biomimetic qualities were assessed to ensure the safety and efficacy. The synthesis of stabilized and capped AgNPs presented a UV–vis–based plasmonic resonance at ∼ 400 nm. The reduction of silver nitrate was further confirmed by the shift in FTIR spectra for -OH around 2870 cm−1. SEM and TEM images revealed cubic shape of the AgNPs. Whereas X-ray diffraction pattern indicated crystalline structure (crystallite size of ∼ 31.14 nm) with an inter-planar spacing value of 2.77, 1.96, and 1.67 Å for (200), (220), and (311) planes, respectively. In addition, AgNPs indicated a steady dispersion, homogeneity, and strong anionic zeta potential (∼ 35.4 mV). The results of antibacterial and antifungal activity demonstrated the potential of phyto-synthesized AgNPs in mitigation of infection associated with tested bacterial strain Bacillus subtilis, Bacillus megaterium, Shigella flexneri, Trichoderma viride, Aspergillus niger, and Penicillium crysogenum. Moreover, the results of hydrogen peroxide-based scavenging, anti-inflammatory, and anti-diabetic study revealed that the biosynthesized AgNPs exhibit an improved biomimetic attribute. Additionally, the biocompatibility assay demonstrated > 80 % of CaCO-2 and L-929 cells viability at 1.67 μg/mL and 3.35 μg/mL, respectively. The anticancer activity of synthesized AgNPs against epithelium-like phenotype oral squamous carcinoma cells (CLS-354/WT) displayed IC50 of 11.58 μg/mL. The results indicate that biogenic produced AgNPs may find suitable use as a potential therapeutic agent due to multifunctional attribute.

The role of selected nutraceuticals in management of prediabetes and diabetes: An updated review of the literature. Part II.

We have already published a review about the results of clinical trials evaluating the effects of selected nutraceuticals on glycemia in humans. In this second part, we describe the role of other nutraceuticals involved in dysglycemia. The available evidence showed promising hypoglycemic effects of the nutraceuticals reviewed both for their efficacy and safety profile. However, contradictory results as regard the efficacy of some supplements such as Allium sativum, Juglans regia, and Lycium barbarum on glucose homeostasis have emerged from some clinical studies. Other nutraceuticals including Aloe vera, Amorphophallus Konjac, Bauhinia forficata, Coccinia, Ganoderma lucidum, Ipomoea batatas, and Lupinus mutabilis require larger and long-term studies rigorously designed to confirm their hypoglycemic effects due to the scarce data available and the poor quality of clinical trials. Further studies are also required for Cinnamomum, Cynara scolymus, Momordica charantia, Olea europaea, and Opuntia streptacantha. Moreover, well-designed large and long-term clinical trials including the use of standardized nutraceutical preparations are necessary for Phaseolus vulgaris and Vaccinium myrtillus.

Trade-off between herbal and allopathic treatments: An ethnopharmacological case study in Rema-kalenga wildlife sanctuary, Bangladesh

The Rema-Kalenga Wildlife Sanctuary (RKWS) is a protected forest in Bangladesh that houses a variety of rare flora and fauna and supports the sustenance of 13 ethnic communities. This forest's indigenous and other inhabitants traditionally have a strong cultural connection to the plants, particularly medicinal plants. Due to modern allopathic medicine's rapid growth and commercial tree species prioritization, many medicinal plants are now on the verge of endangerment. Under such circumstances, it is crucial to explore how the local community perceives the importance of herbal treatments in contrast to allopathy, the underlying reasons for their perceptions, and the specific ailments for which they use the plants. The main objectives are: 1) to evaluate the perceptions of the local community towards allopathy and herbal medicine using Nussbaum's central capabilities approach, 2) to identify medicinal plant diversity, therapeutic usages, and quantitative indices, 3) to determine the factors that influence the use of medicinal plants. Repeated interviews and field surveys were conducted at the RKWS, interviewing 145 people, including the indigenous community (72.42 %) and traditional healers (8.27 %) from the surrounding seven villages. The study identified 51 medicinal plant species belonging to 39 families for their potent medicinal properties in treating various ailments. The predominant parts of the plants used in the treatments were leaves and roots. The uses were classified into 12 categories according to Nussbaum's central capabilities. The findings identified Aloe vera, Phyllanthus emblica, and Azadirachta indica as highly culturally important species. In contrast, Terminalia arjuna, Swertia chirata, and Azadirachta indica were found to have the highest relative importance. The underlying determinants influencing the preferences of individual users towards herbal medicine were income from agroforestry, beliefs, knowledge, and ethnicity, as revealed by the analysis of the ordinal logit model. The respondents viewed their strong inclination toward herbal medicine with many positive attitudes. Herbal medicine users held a negative perception of allopathy except for affiliation and practical reasons being viewed as the positive outcomes. Conversely, allopathic medicine users expressed mixed perceptions towards the treatment, with both positive and negative aspects being identified. Promoting the sustainable use of medicinal plants and their conservation efforts is imperative for the benefit of present and future generations in this region.

Green nanotechnology for the enhancement of antibacterial properties in lining leather: MgO-chitosan nanocomposite coating

Antimicrobial nanomaterials have received a lot of interest in recent years due to their potential to fight against microbial degradation, a common problem in leather products. In this study, a nanocomposite was synthesized with MgO nanoparticles prepared by Aloe vera leaf extract and chitosan (CS), as an innovative solution to this problem. Three nanocomposite samples (C1, C2, and C3) were formulated with varying ratios of MgO and chitosan and evaluated for antimicrobial efficacy against Escherichia coli and Bacillus subtilis. Leather treated with MgO/Chitosan nanocomposite (MgO/Chitosan-1:1) exhibited substantial inhibition zones of 13 mm and 12 mm against E. coli and B. subtilis, respectively. Characterization of MgO nanoparticles, chitosan, and MgO/CS nanocomposite was performed through FTIR, XRD, SEM, TGA, and cytotoxicity tests. The average particle size and crystallite size of MgO nanoparticles were found as 136 nm and 10.3 nm, respectively and a weight loss of 67 % for MgO/CS nanocomposite in thermogravimetric analysis. FTIR confirmed the successful incorporation of MgO nanoparticles into the chitosan matrix, evidenced by the presence of characteristic functional groups. Application of nanocomposite onto lining leather via spraying resulted in finished leather with improved color rub fastness, perspiration fastness, and thermal stability compared to untreated leather. In comparison to dry color rub fastness, wet color rub fastness was notably improved by the MgO/CS nanocomposite, with gray scale ratings ranging from 4/5 to 5. Perspiration fastness was marginally enhanced by the MgO/CS coating, with gray scale ratings ranging from 4/5 to 5 for both grain and flesh samples. Specifically, the coated leather exhibited a water vapor permeability (WVP) of 9.94 mg cm−2.hr−1 that was lower than both uncoated (12.37 mg cm−2.hr−1) and PVA-coated (11.22 mg cm−2.hr−1) leather. This study presents a promising solution to the challenge of microbial degradation in leather products and highlights the potential of natural sources for synthesizing functional nanocomposites with diverse applications in materials science and biotechnology.

High strength “breathable” glycosilicone/Aloe vera polysaccharide-based gel dressing for efficient wound repair

Medical wound dressings are effective in protecting wounds, maintaining moisture, creating an optimal healing environment and accelerating wound healing. However, their deficiencies in mechanical properties, adhesion and prevention of adhesion to the wound bed have been identified as limiting factors for their therapeutic efficacy in wound healing. To address these issues, we prepared glycosilicone gel dressings consisting of hydrophobic polysiloxanes and highly hydrophilic polysaccharides via ester exchange and silicone hydrogen addition reactions. Silicone gel dressings exhibit skin-like “respiratory” properties, with good permeability to O2 and CO2. Additionally, elongation and other important parameters are similar to those of the skin, which provides a foundation for the application of silicone gels in the field of wound dressings. The introduction of Aloe vera polysaccharide (AP) results in the glycosilicone gel exhibiting certain mechanical properties, including a tensile strength of 0.35 MPa and an adhesion force of 10 N/m. Furthermore, a mouse model of total skin defect demonstrated that the wound healing rate of the mice on the 12th day was 98 %, which effectively promotes wound healing. Consequently, the glycosilicone gel is anticipated to be an optimal wound dressing.

IoT Smart Gardening on Herbal Plant and Analytic Virtualization Platform System

The Internet of Things (IoT) is an emerging technology developing recently. The technology of IoT allows users to communicate with controllers and sensors, which are widely used in the agricultural sector, such as farming and weather forecasts. Recently, it has been identified that traditional herbal home gardens are difficult to monitor where herbal plants are sensitive and need a proper monitor. This research has developed an IoT smart gardening for herbal plant systems that helps to analyze four herbal plant types: Aloe Barbadensis miller, Salvia Rosmarimus, Clinacanthus nutans, and Curcuma. The system was designed using a NodeMCU ESP32 controller, soil moisture sensor, and DHT11 temperature and humidity sensor. The collected data was monitored in real-time on the Blynk platform via mobile phones and web browsers on sunny and rainy days. The result shows that the highest temperature on a sunny day was captured at 30°C, and the lowest was 26°C. However, during a rainy day, the highest temperature captured is 28°C and the lowest was 24°C. The highest humidity percentage on a sunny day was 80%, and the lowest was 40%, while the highest humidity on a rainy day was 98%, and the lowest was 68%. The soil moisture data that captured the water content of the soil of each herbal plant on a sunny day has been lost due to high temperatures. However, each herbal plant barely lost its water content due to low temperature and high humidity percentage conditions. The comparison showed that temperature, humidity, and weather could affect the water content in the soil. This research has significantly improved the agriculture sector in monitoring herbal plants and moving from traditional planting with an IoT system concept.

Influence of Aloe Vera Gel on Germination and Early Growth of Tomato (Solanum lycopersicum) Seedlings in the Nursery

Tomato (Solanum lycopersicum L.) nursery production often relies heavily on chemical inputs to ensure vigorous seedling growth, which may have environmental and economic drawbacks. This study aimed to evaluate the efficacy of Aloe vera gel as a natural alternative to chemical treatments for improving germination and early seedling growth of Cobra 26 tomato seeds. The study used a factorial block design to compare the effects of seed treatments (Aloe vera gel coating, mancozeb, and untreated control) and substrate types (unfertilised topsoil, NPK-fertilised topsoil, and Aloe vera gel mixed with topsoil) on seed germination and seedling growth over three nursery cycles. Seeds coated with Aloe vera gel demonstrated the highest germination rate (90.53%) and fastest germination time (3 days), outperforming both mancozeb-treated and control seeds in germination kinetics. Growth parameters such as seedling height and leaf number were significantly influenced by substrate type (p<0.03), with no notable differences between NPK and Aloe vera-treated substrates. The study suggests that Aloe vera gel, both as a seed coating and soil additive, offers a promising, eco-friendly alternative to chemical treatments, enhancing seed germination and early seedling growth in tomatoes

Enhanced Catalytic Activity for Production of Biodiesel from Aloe vera Oil and the Removal of Methyl Violet Dye using Polyaniline-Fe3O4 Magnetic Nanocomposite

The aim of this work was to use a unique technique to maximize the efficiency and cost-effectiveness of biodiesel synthesis utilizing Aloe vera oil. Moreover, in order to facilitate the magnetic separation from the resultant mixture, lipase was immobilized on a magnetic nanocomposite consisting of polyaniline (PANI) and Fe3O4. Utilizing XRD, SEM, TGA and FTIR spectroscopy, the nanocomposite was thoroughly characterized. The results indicated that the immobilized lipase exhibited enhanced thermal stability and a modified optimum pH compared to its free form. Using immobilized lipase also significantly improved the biodiesel conversion yield from 27% with free enzyme to 60%. Remarkably, after five cycles of reutilization in the production of biodiesel, the immobilized lipase retained 90% activity. The catalytic effectiveness of lipase during biodiesel synthesis was significantly enhanced and its resistance to heat and pH fluctuations was strengthened by this novel immobilization approach. Beyond its potential usage in biodiesel production, the PANI-Fe3O4 magnetic nanocomposite also demonstrated photocatalytic removal and degradation of methyl violet dye from aqueous solution.
