Novel insights into the molecular mechanisms underlying anti-nociceptive effect of myricitrin against reserpine-induced fibromyalgia model in rats: Implication of SIRT1 and miRNAs

Ethnopharmacological relevanceManilkara zapota (L.) P. Royen, also termed sapodilla or chikoo, is a significant plant in ethnomedicine because of its long history of traditional medical applications. In diverse cultures, sapodilla is believed to protect against oxidative stress, inflammation, and some chronic diseases because of its high antioxidant content. The naturally occurring antioxidant myricitrin (MYR) flavonoid is primarily found in the leaves and other plant parts of sapodilla and it is well-known for having therapeutic qualities and possible health advantages. Aim of the studyTo appraise the possible impact of MYR on a rat model of reserpine-induced fibromyalgia (FM) and explore its mechanism of action. Materials and methodsIsolation and identification of MYR with more than 99% purity from Manilkara zapota leaves were primarily done and confirmed through chromatographic and spectrophotometric techniques. To develop FM model, reserpine (RSP) was injected daily (1 mg/kg, s.c.) for three successive days. Then, MYR (10 mg/kg, i.p.) and pregabalin (PGB, 30 mg/kg, p.o.) were given daily for another five days. Behavioral changes were assessed through open field test (OFT), hot plate test, and forced swimming test (FST). Further analyses of different brain parameters and signaling pathways were performed to assess monoamines levels, oxidative stress, inflammatory response, apoptotic changes as well as silent information regulator 1 (SIRT1) and micro RNAs (miRNAs) expressions. ResultsFrom High-Performance Liquid Chromatography (HPLC) analysis, the methanol extract of sapodilla leaves contains 166.17 μg/ml of MYR. Results of behavioral tests showed a significant improvement in RSP-induced nociceptive stimulation, reduced locomotion and exploration and depressive-like behavior by MYR. Biochemical analyses showed that MYR significantly ameliorated the RSP-induced imbalance in brain monoamine neurotransmitters. In addition, MYR significantly attenuated oxidative stress elicited by RSP via up-regulating nuclear factor erythroid 2-related factor 2 (Nrf2) and heme oxygenase-1 (HO-1) protein expressions, enhancing superoxide dismutase (SOD) and catalase (CAT) activities, and reducing malondialdehyde (MDA) content in brain. The RSP-provoked inflammatory response was also diminished by MYR treatment as shown by a significant decreased NOD-like receptor protein 3 (NLRP3) inflammasome expression along with reduced levels of interleukin 1 beta (IL-1β) and nuclear factor-κB (NF-κB). Furthermore, the anti-apoptotic activity of MYR was demonstrated by a marked rise in Bcl-2-associated X protein (BAX)/B cell lymphoma-2 (Bcl-2) ratio by lowering Bcl-2 while increasing BAX levels. In addition, MYR treatment significantly boosted the expression of SIRT1 deacetylase in RSP-treated animals. Interestingly, molecular docking showed the ability of MYR to form a stable complex in the binding site of SIRT1. Regarding miRNAs, MYR effectively ameliorated RSP-induced changes in miR-320 and miR-107 gene expressions. ConclusionOur findings afford new insights into the anti-nociceptive profile of MYR in the RSP-induced FM model in rats. The underlying mechanisms involved direct binding and activation of SIRT1 to influence different signaling cascades, including Nrf2 and NF-κB/NLRP3 together with modulation of miRNAs. However, more in-depth studies are needed before proposing MYR as a new clinically relevant drug in the management of FM.

Resistome Signature and Antibiotic Resistance Mechanisms in Rhizospheric Soil Bacteriomes of Mecca Region, Saudi Arabia: Insights into Impact on Human Health.

The objective of this investigation is to ascertain the distinctive profile of the rhizospheric soil resistome within the Mecca region, while also evaluating the potential risks associated with the horizontal transfer of resistome determinants to the open environment and human clinical isolates. We have made metagenomic whole-genome shotgun sequencing for rhizospheric microbiomes of two endemic plants, namely Moringa oleifera and Abutilon fruticosum. The rhizospheric resistomes of the two plants and the abundance of antibiotic resistance genes (ARGs) were identified by cross-referencing encoded proteins with the comprehensive antibiotic resistance database (CARD). The identified ARGs were then analyzed for their antimicrobial resistance (AMR) mechanisms. Predominantly within this soil are the two bacterial species Pseudomonas aeruginosa and Mycobacterium tuberculosis. These opportunistic human pathogens are implicated in respiratory infections and are correlated with heightened mortality rates. The most prevalent array of ARGs existing in this soil comprises mexA, mexC, mexE, and cpxR, associated with mechanisms of antibiotic active efflux, along with ACC(2), ACC(3), AAC(6), and APH(6), in addition to arr1, arr3, arr4, iri, rphA, and rphB, implicated in antibiotic inactivation. Furthermore, vanS, vanR, and vanJ are identified for antibiotic target alteration, while rpoB2 and RbpA are noted for antibiotic target replacement and protection, respectively. These mechanisms confer resistance against a diverse spectrum of drug classes encompassing fluoroquinolones, aminoglycosides, glycopeptides, and rifampicins. This study underscores the potential hazards posed to human health by the presence of these pathogenic bacteria within the rhizospheric soil of the Mecca region, particularly in scenarios where novel ARGs prevalent in human populations are harbored and subsequently transmitted through the food chain to human clinical isolates. Consequently, stringent adherence to good agricultural and food transportation practices is imperative, particularly with regard to edible plant parts and those utilized in folkloric medicine.

ОПРЕДЕЛЕНИЕ ФИТОТОКСИЧНОСТИ СУБСТРАТОВ НА ОСНОВЕ ОТХОДОВ АКТИВНОГО ИЛА В ВЕГЕТАЦИОННЫХ ОПЫТАХ

The aim of the study is to determine the phytotoxicity of components and substrates using waste from the treatment facilities of the Arkhangelsk Pulp and Paper Mill. The substrates were made on the basis of high-moor peat with a decomposition degree of 15 %, with the addition of Biohumus Arkhangelsky, which is composted residual activated sludge from treatment facilities (RAS). To test extracts from materials used to prepare experimental substrates, oats (Avena sativa L.) and watercress (Lepidium sativum L.) were used. Comparison was carried out with distilled water and Knop's mixture. To select the optimal ratio of residual activated sludge and peat for plant growth, a model experiment was conducted with growing oats. The substrates prepared by the volume of fractions with a gradation of activated sludge of 10 % were studied. It was found that composted activated sludge does not have phytotoxicity in relation to the test objects. The extract based on dewatered activated sludge of the treatment facilities of the Arkhangelsk Pulp and Paper Mill does not have a depressing effect on the germination of test objects – oat and watercress seeds, and according to the indicators of the length of the root and coleoptile of oats, it has a stimulating effect comparable to or exceeding the effect of the Knop mixture. Phytostimulating effect of peat extract was not detected. The addition of OAI to high-moor peat during the preparation of substrates has a positive effect on growth indicators. An increase in the length of the stem and root, the mass of the underground and aboveground parts of plants is noted. The optimal addition to the substrate for growing oats is composted activated sludge in the amount of 10–20 %. With large proportions of composted activated sludge waste (more than 40 %), oat growth decreases, but the mass of stems and roots increases.

Essential Oil Content, Composition and Free Radical Scavenging Activity from Different Plant Parts of Wild Sea Fennel (Crithmum maritimum L.) in Montenegro.

This study was conducted to determine the sea fennel essential oil (SFEO) yield, composition, and antioxidant activity of leaves, stem, inflorescences, and umbels from seeds of wild sea fennel (SF) (Crithmum maritimum L.) from the Montenegro coast. The chemical composition of isolated essential oil was determined by GC/MS and GC/FID analyses. The antioxidant activity was determined using the DPPH assay. The maximum SFEO yield was found in umbels with seeds (4.77 mL/100 g p.m.). The leaves contained less EO (0.52 mL/100 g p.m.) than immature inflorescence (0.83 mL/100 g p.m.) The minimum EO content was found in the stem (0.08%). Twenty components were isolated from SFEO leaves, twenty-four from inflorescence, thirty-four components from the stem, and twenty-one components from umbels with seeds. Limonene (62.4-72.0%), γ-terpinene (9.5-14.0%), α-pinene (1.4-5.8%), and sabinene (1-6.5%) were found to be the main components of the SFEO from monoterpene hydrocarbons as dominant grouped components (86% to 98.1%). SF plant parts showed differences in chemical profiles, especially in specific and low-represented ingredients. (E)-anethole (4.4%), fenchone (0.5%), and trans-carveol (0.2%) were present only in umbel with seeds, while the β-longipipene (0.5%), (E)-caryophyllene (0.5%), and (2E)-decenal (0.2%) were found only in the stems. The degree of DPPH radical neutralization increased with incubation time. The SFEO isolated from the stems showed stronger antioxidant activity during the incubation times of 20 and 40 min (EC50 value of 5.30 mg/mL and 5.04 mg/mL, respectively) in comparison to the SFEO isolated from the other plant parts. The lowest antioxidant activity was obtained with the SFEO leaves (155.25 mg/mL and 58.30 mg/mL, respectively). This study indicates that SFEO possesses significant antioxidant activities and is animportant component in the food and pharmaceutical industries. It is important to preserve the existing gene pool and biodiversity with rational use SF for the extraction of high-quality essential oils.

Eco-friendly dye from the fruits of Memecylon randerianum S. M. Almeida & M. R. Almeida – An application study

Over the last few years, the global scenario has been witnessing an escalating urge to develop and use more eco-friendly products, like natural plant-based dyes, due to growing awareness about the harmful effects of synthetic products on mankind and nature. The present study is a novel eco-friendly textile application approach of natural fruit dyes extracted from Memecylon randerianum. Fresh aqueous fruit extracts were applied to cotton fabrics, and colour variations were achieved by pre-mordanting using both chemical and natural mordants. In addition to this, the effectiveness of memecylon dye in combination with turmeric dye was also evaluated. Various important attributes like colour strength, colour fastness, and a loss percentage of colour were analysed based on reflectance. Fabric dyed with mordant yielded darker bluish-purple to black shade than those dyed without mordant. However, the combination dye yielded brighter hues of yellow and green. In general, the dye showed moderate to very good fastness with the least loss percentage of colours. Tannins, a major class of compounds contributing to the dyeing potential of the plant part, were also quantified. Besides these, the dye also showed positive antimicrobial activity against the bacterial strains Staphylococcus aureus and Salmonella typhi. Hence, owing to its multiple favourable qualities, the study revealed that fresh dye extracts from M. randerianum fruits could be used as an effective eco-friendly alternative to hazardous synthetic dyes.

Exploring the wound healing activity of phytosomal gel of Annona squamosa and Cinnamomum tamala leaves ethanolic extracts with antioxidant and antimicrobial activities in S aureus infected excision wound model

Wound healing is a natural process but it is impaired in certain conditions like age, stress, health, immunity status and microbial infection. Particularly in cases of chronic wounds, infection is nearly often the main and unavoidable obstacle to wound healing. For this purpose, leaves of Annona squamosa and Cinnamomum tamala were selected based on their ethnopharmacological uses and reported pharmacological activities. The ethanolic extracts of both plant parts i.e. ethanolic extracts of Annona squamosa (ASEE) and Cinnamomum tamala (CTEE) were evaluated for their antioxidant and antimicrobial activities individually as well as in 1:1 combination as Polyherbal Ethanolic extract (PHEE). In our previous work both these ethanolic extracts were combined and phytosomes were prepared by thin layer hydration method and optimized for vesicle size and entrapment efficiency. The phytosomes were then incorporated into Carbopol gel matrix. In this present study the selected phytosomal gel was tested in two different concentrations (2% and 5%) for in vivo wound healing activity using S. aureus infected excision wound model. The various parameters examined were percentage wound contraction, epithelization period, bacteriological quantification, biochemical parameters like Superoxide dismutase (SOD), Catalase and hydroxyproline. The PHEE exhibited synergistic antioxidant activity. The PHEE also showed enhanced antimicrobial activity against bacteria namely gram-positive S. aureus, gram-negative E. Coli. The phytosomal gel showed increased wound contraction, reduced time of epithelization, increased hydroxyproline content, increased levels of SOD and Catalase enzymes and reduced bacterial load when compared with Povidone iodine ointment as standard in S. aureus infected excision wound model.
