Effect of West Indian Bay Leaf (Pimenta racemosa) and Turmeric (Curcuma longa) Essential Oils on Preserving Raw Chicken Breasts.

While the use of chemical preservatives in meat may appear to be tremendously advantageous, they have long been purported to increase the risk of incidence of certain types of cancers. Consequently, many people have opted for minimally processed alternatives. This consumer shift has placed substantial pressure on the food industry to implement more natural alternatives to these synthetic preservatives in the meat industry. Research on plant extracts as potential agents for food additives is increasing. The bioactive components present in West Indian bay leaf and turmeric essential oils have a promising potential for use as novel, green preservatives in the meat industry. Raw chicken breast samples (28 g) were each treated with different volumes (0.5, 1 and 1.5 mL) of the essential oil of West Indian bay leaf or turmeric or their mixture (1:1 to make up a final volume of 0.5, 1 and 1.5 mL). Physicochemical, microbiological and sensory evaluations were performed on the fresh and treated samples stored for 14 days at 4 °C. The West Indian bay leaf oil had a higher extraction yield and total phenolic content, while the turmeric oil had a higher total flavonoid content. The most effective treatments, compared to the control, significantly (p<0.05) minimized the pH increase by 13.9 % (1.5 mL bay leaf oil), reduced texture loss by 44.8 % (1.5 mL oil mixture) and reduced protein loss by 98.9 % (1 mL bay leaf oil). Most treated samples had reduced microbial loads, with the turmeric oil showing the highest efficacy against lactic acid bacteria, yeasts and moulds. Treated samples had significantly higher (p<0.05) sensory scores than the control on the final day of storage, with the 1.5 mL oil mixture proving to be the most effective, as the storage life of the chicken breast sample was extended by 6 days. This study has shown for the first time that the essential oil from turmeric and West Indian bay leaf can extend the shelf life of raw chicken breast and highlights the potential of the oil as natural preservative agents in lieu of synthetic alternatives.

Turmeric Gel as alternative Non-Vital Pulpotomy medicament in Primary teeth- A Randomized Controlled Trial

&lt;p&gt;&lt;strong&gt;Background and objective: &lt;/strong&gt;Formocresol is a gold standard medicament in both vital and non-vital Pulpotomies due to its potent antibacterial potential but, it has a controversial nature due to its side effects. Therefore, the demand for natural alternatives of Formocresol as a pulp dressing material, with few or no side effects, became imperative. The purpose of the study was to introduce Turmeric gel as non-vital Pulpotomy medicament in primary teeth by evaluating its antibacterial effect against&lt;em&gt; Streptococcus mutans&lt;/em&gt; and &lt;em&gt;Lactobacillus acidophilus&lt;/em&gt;.&lt;/p&gt;&#x0D; &lt;p&gt;&lt;strong&gt;Method: &lt;/strong&gt;It was a multi-arm parallel Randomized Controlled Trial in which sixty patients aged between 4 to 8 years, each containing at-least one non-vital primary molar, were selected and randomly divided into Group A (Formocresol) and Group B (Turmeric gel). Non-vital Pulpotomy was performed by removing the coronal necrotic pulp. Sterile paper points were dipped in the root canals and taken to the laboratory. Cotton pellets soaked in the respective medicaments were placed over the root canal orifices and filled temporarily. Patients were recalled after one week. Samples were again taken, and tooth restored. Comparison between bacterial count at baseline and after one week of treatment was made and expressed as Colony-Forming Units/ml (CFU/ml).&lt;/p&gt;&#x0D; &lt;p&gt;&lt;strong&gt;Results:&lt;/strong&gt; There was a significant reduction in median &lt;em&gt;Streptococcus mutans&lt;/em&gt; and &lt;em&gt;Lactobacillus acidophilus&lt;/em&gt; bacterial count in each group after one week of treatment (p &amp;lt; 0.001). Formocresol showed higher average reduction than Turmeric gel. However, statistically, the difference was insignificant indicating that both the medicaments possessed comparable antibacterial effect.&lt;/p&gt;&#x0D; &lt;p&gt;&lt;strong&gt;Conclusion:&lt;/strong&gt; Turmeric gel was found as effective alternative to Formocresol.&lt;/p&gt;&#x0D; &lt;p&gt;&lt;strong&gt;Randomized Controlled Trial registration number in ClinicalTrials.gov:&lt;/strong&gt; NCT05801354&lt;/p&gt;&#x0D; &lt;p&gt;&amp;nbsp;&lt;/p&gt;

Effects of Allium sativum on Growth Performance, Kidney and Liver Function Markers, Microbial Flora and Feed Digestibility in Broiler Chickens

Introduction: The global ban on antibiotics as a feed additive, prompted by concerns over microbial resistance and the accumulation of antibiotic residues in animal products, has urged researchers to explore natural alternatives. These alternatives modulate the gut microbiota and enhance animal production performance. This study aimed to assess the impact of Allium sativum on the production performance of broiler chickens. Materials and methods: A total of 280 day-old broiler chicks were examined for 42 days. After being sexed, they were randomly allocated into five groups, each consisting of 14 chicks, with four replications. The control group was fed on a ration without additives (R0-). The treatment groups consisted of a control diet supplemented with 1 g of antibiotic Doxycycline® per kg of basal diet and per liter of drinking water (R0+) and 5 g garlic per kg of basal feed and also per liter of drinking water (RAs), respectively. To facilitate the oral administration, the solution was absorbed by charcoal from the fruit stones of Canarium schweinfurthii at a rate of 100 g and 100 ml per kg of diet and per liter of drinking water, respectively. The investigated parameters included growth performance, microbial flora, markers of kidney, and liver function, and feed digestibility. Results: The results revealed Allium sativum significantly decreased feed intake, feed conversion ratio, serum aspartate aminotransferase, alanine aminotransferase, and urea levels regardless of the administration mode in broiler chickens, compared to the negative control. When administered through both feed and drinking water, garlic significantly increased live weight, weight gain, and lactic acid bacteria count, compared to the negative control. Feeding garlic to broilers had insignificantly affected the digestibility of feed components irrespective of the administration mode. Conclusion: In conclusion, Allium sativum can effectively serve as a feed additive in broiler diets or drinking water, promoting growth performance without harming kidney and liver functions. The present findings help address concerns about antibiotic resistance and residues in poultry products.

Rhus microphylla leaves extracts obtained by ohmic heating: Physicochemical composition and bioactive properties

Rhus microphylla Engel. Ex A. Gray is a traditional plant used in folk medicine for various conditions, yet research on its biological potential is limited. It is important to explore its biological effects and associated bioactive compounds, aiming to propose natural alternatives for pharmaceuticals and sustainable agriculture. Thus, this study aims to assess the bioactive properties of its leaves (RmL) through various extracts, including aqueous and hydroalcohol (1:1), obtained by means of ohmic heating extraction for 5 and 10 min (A5, A10, H5, H10). The extracts were evaluated for their antioxidant, antiproliferative, antibacterial, and insecticidal activities. Aqueous extraction demonstrated higher recovery of phenolic compounds such as gallic acid and catechin, while other compounds were also detected in lower concentrations (epicatechin gallate, ferulic acid, 2-hydroxycinnamic acid, and myricetin). All extracts showed antiproliferative activity against the A549 cell line (lung cancer), with less effect on the HeLa cell line (human cervix carcinoma), while none exhibited cytotoxicity against the noncancerous ARPE-19 cell line. Aqueous extracts displayed notable antimicrobial effects, particularly A10 against Staphylococcus aureus. In insecticidal assessments, H5 emerged as the most effective treatment against Musa domestica and Plutella xylostella. This study pioneers the evaluation of RmL extracts, revealing promising bioactivity with selective extraction conditions for further applications in various industrial fields.

Exploring Periostracum as an Alternative Root Canal Irrigant: Insights From Zebrafish Embryo Experiments.

Objectives Root canal treatments aim to eliminate biofilms effectively. Considering the limitations of chemical irrigants, there is growing interest in natural alternatives like periostracum due to their antibacterial and fouling-resistant properties. This study aimed to assess periostracum's toxicity as a root canal irrigant by investigating its effects on zebrafish embryos' heart rate, survival rate, and hatching rate, as well as inflammation studies using neutral red assays comparing it to standard irrigants like ethylenediaminetetraacetic acid (EDTA), chlorhexidine (CHX), and sodium hypochlorite (NaOCl). Materials and methods Zebrafish embryos were exposed to varying concentrations of periostracum irrigant and standard irrigants. Heart rate, survival rate, and hatching rate were evaluated as indicators of developmental toxicity using microscopy. Statistical analysis, utilizing GraphPad Prism software (version 5.03, GraphPad Software, LLC, San Diego, California, United States), involved one-way ANOVA and Tukey's post-hoc test to determine significance levels (p < 0.05) across control and other groups based on triplicate means and standard deviation. Results The periostracum irrigant demonstrated superior survival rates, heart rates, and hatching rates at specific concentrations compared to standard irrigants (p < 0.01), maintaining favorable heart rates and hatching rates at those concentrations. However, higher concentrations resulted in diminished hatching rates (p < 0.05). Additionally, this study revealed increased inflammation when larvae were treated with NaOCl, EDTA, and CHX. Conversely, no inflammation was observed when subjected to periostracum irrigants. These findings suggest potential advantages of periostracum as a root canal irrigant due to its increased biocompatibility. Conclusion Periostracum displayed promising attributes in zebrafish embryo experiments, such as stable heart rate, hatching rate, and survival rate, along with reduced developmental toxicity and inflammation, indicating potential advantages as a root canal irrigant, including reduced toxicity compared to conventional agents. Further research involving diverse demographics and long-term effects is crucial to validate periostracum's clinical applicability and safety in endodontic therapies.

Various phytochemicals were found in S. acmella extract which may be responsible for its anti- bacterial property.Conclusion: S. acmella extract shows a significant antibacterial effect against the major periodontal pathogens and hence may be a potential natural alternative for controlling the growth of these bacteria.

Maximal Objectives in the Multiarmed Bandit with Applications

In several applications of the stochastic multiarmed bandit problem, the traditional objective of maximizing the expected total reward can be inappropriate. In this paper, we study a new objective in the classic setup. Given K arms, instead of maximizing the expected total reward from T pulls (the traditional “sum” objective), we consider the vector of total rewards earned from each of the K arms at the end of T pulls and aim to maximize the expected highest total reward across arms (the “max” objective). For this objective, we show that any policy must incur an instance-dependent asymptotic regret of [Formula: see text] (with a higher instance-dependent constant compared with the traditional objective) and a worst case regret of [Formula: see text]. We then design an adaptive explore-then-commit policy featuring exploration based on appropriately tuned confidence bounds on the mean reward and an adaptive stopping criterion, which adapts to the problem difficulty and simultaneously achieves these bounds (up to logarithmic factors). We then generalize our algorithmic insights to the problem of maximizing the expected value of the average total reward of the top m arms with the highest total rewards. Our numerical experiments demonstrate the efficacy of our policies compared with several natural alternatives in practical parameter regimes. We discuss applications of these new objectives to the problem of conditioning an adequate supply of value-providing market entities (workers/sellers/service providers) in online platforms and marketplaces.

Emerging nitrogen-fixing cyanobacteria for sustainable cotton cultivation

Amid growing environmental concerns and the imperative for sustainable agricultural practices, this study examines the potential of nitrogen-fixing cyanobacteria as biofertilizers, particularly in cotton cultivation. The reliance on synthetic nitrogen fertilizers (SNFs), prevalent in modern agriculture, poses significant environmental challenges, including greenhouse gas emissions and water system contamination. This research aims to shift this paradigm by exploring the capacity of cyanobacteria as a natural and sustainable alternative. Utilizing advanced metabarcoding methods to analyze the 16S rRNA gene, we conducted a comprehensive assessment of soil bacterial communities within cotton fields. This study focused on evaluating the diversity, structure, taxonomic composition, and potential functional characteristics of these communities. Emphasis was placed on the isolation of native N2-fixing cyanobacteria strains rom cotton soils, and their subsequent effects on cotton growth. Results from our study demonstrate significant plant growth-promoting (PGP) activities, measured as N2 fixation, production of Phytohormones, Fe solubilization and biofertilization potential of five isolated cyanobacterial strains, underscoring their efficacy in cotton. These findings suggest a viable pathway for replacing chemical-synthetic nitrogen fertilizers with natural, organic alternatives. The reintegration of these beneficial species into agricultural ecosystems can enhance crop growth while fostering a balanced microbial environment, thus contributing to the broader goals of global sustainable agriculture.

Comparison of the Scolicidal Activity of Two Leaves Extracts of Myrtus communis from Algeria Against Echinococcus granulosus Sensu Lato Protoscoleces.

During cystic echinococcosis surgery, the use of scolicidal agents such as hypertonic saline (20%) aims to reduce the risk of infection recurrence, but most of the used agents are associated with undesirable side effects. Therefore, the use of natural scolicidal agents such as medicinal plant extracts could reduce these medical issues. The present study aimed to compare in vitro the scolicidal activity between two extracts of the medicinal plant Myrtus communis from Algeria against Echinococcus granulosus sensu lato protoscoleces. Theethanolic and aqueous extraction of plant leaveswas performed. Phytochemical analysis by gas chromatography-tandem mass spectrometry (GC-MS/MS), determination of total phenolic and flavonoid contents, and in vitro antioxidant activity by DPPH were evaluated for both extracts. Finally, the in vitro scolicidal activity was tested by different concentrations. The viability was evaluated by the eosin exclusion test. Thephytochemical analysis revealed 28 components for the ethanolic extract and 44 components for the aqueous extract. The major components were 2'-hydroxy-5'-methoxyacetophenone and 4-amino-2-methylphenol, respectively. The total phenolic and flavonoid contents were 45.9 ± 0.085mg of gallic acid equivalent per g of extract (GAE/g E) and 16.5 ± 0.004mg of quercetin equivalent per g (QE/g E) for the ethanolic extract, and 36.5 ± 0.016mg GAE/g E and 18.2 ± 0.023mg QE/g E for the aqueous extract, respectively. Furthermore, ethanolic and aqueous extracts of M. communis gave a value of IC50 = 0.009 ± 0.0004mg/ml and IC50 = 0.012 ± 0.0003mg/ml for theantioxidant activity, respectively. The in vitro scolicidal activity with concentrations of 50, 75, 100, and 150mg/ml was tested for 5, 10, 15, and 30min, and 5, 10, 15, 30, 60, 90, and 120min for ethanolic and aqueous extracts, respectively. The mortality rate of protoscoleces at concentrations of 100 and 150mg/ml was 98.8 and 100%, respectively, after 5min of exposure to the ethanolic extract, while this rate was 100% at the same concentrations only after 60min of exposure to theaqueous extract. The ethanolic extract showed a stronger scolicidal activity against E. granulosus s.l protoscoleces than the aqueous extract. In the future, otherinvestigations are necessary to elucidate the mechanism of action and the possible toxicity on human cells. Moreover, experimental animal studies are required to investigate the efficacy of different extracts of this plant and its components as natural anti-parasitic alternatives for the treatment of human cystic echinococcosis.

Exploration of Antileishmanial Compounds Derived from Natural Sources.

Leishmaniasis is a deadly tropical disease that is neglected in many countries. World Health Organization, along with a few other countries, has been working together to protect against these parasites. Many novel drugs from the past few years have been discovered and subjected against leishmaniasis, which have been effective but they are quite expensive for lower-class people. Some drugs showed no effect on the patients, and the longer use of these medicines has made resistance against these deadly parasites. Researchers have been working for better medication by using natural products from medicinal plants (oils, secondary metabolites, plant extracts) and other alternatives to find active compounds as an alternative to the current synthetic drugs. To find more potential natural products to treat Leishmania spp, a study has been conducted and reported many plant metabolites and other natural alternatives from plants and their extracts. Selected research papers with few term words such as natural products, plant metabolites, Leishmaniasis, in vivo, in vitro, and treatment against leishmaniasis; in the Google Scholar, PubMed, and Science Direct databases with selected research papers published between 2015 and 2021 have been chosen for further analysis has been included in this report which has examined either in vivo or in vitro analysis. This paper reported more than 20 novel natural compounds in 20 research papers that have been identified which report a leishmanicidal activity and shows an action against promastigote, axenic, and intracellular amastigote forms. Medicinal plants, along with a few plant parts and extracts, have been reported as a possible novel anti-leishmanial medication. These medicinal plants are considered nontoxic to Host cells. Leishmaniasis treatments will draw on the isolated compounds as a source further and these compounds compete with those already offered in clinics.

Potential of Organic Acids, Essential Oils and Their Blends in Pig Diets as Alternatives to Antibiotic Growth Promoters.

Over the years, the use of management and feeding strategies to enhance pig productivity while minimizing the use of antibiotic growth promoters has grown. Antibiotic growth promoters have been widely used as feed additives to reduce diet-related stress and improve pig performance. However, increasing concern about the consequences of long-term and increased use of antibiotic growth promoters in animal production has led to a paradigm shift towards the use of natural organic alternatives such as plant essential oils and organic acids in pig nutrition to enhance growth. Antibiotic growth promoters endanger human health by allowing multidrug-resistant genes to be transferred horizontally from non-pathogenic to pathogenic bacteria, as well as directly between animals and humans. Scientific research shows that alternative growth promoters such as essential oils and organic acids appear to improve pigs' ability to prevent pathogenic bacteria from colonizing the intestinal system, stabilizing the gut microflora and promoting eubiosis, as well as improving immunity and antioxidant stability. The purpose of this review was to provide an in-depth review of organic acids and essential oils as growth promoters in pig production, as well as their effects on productivity and meat quality. Organic acids and essential oils in pig diets are a safe way to improve pig performance and welfare while producing antibiotic-free pork.

Prosopis Africana Extracts as Potential Natural Alternatives to Synthetic Antibiotics and a Key for Sustainable Broiler Production: a Review

The chicken sector is more vulnerable to antimicrobial resistance, the buildup of toxic or dangerous residues in meat and eggs, and environmental contamination as a result of the widespread and careless use of antibiotics in most nations. Natural solutions, such as medicinal plants, are required to address these issues. These plants have been shown to contain a variety of phytochemicals, including phenols, flavonoids, terpenoids, tannins, alkaloids, and saponins. These chemicals endow plants with a multitude of medicinal qualities. One of the many alternatives to antibiotics is Prosopis africana extract, which includes stem bark, leaves, roots, and their essential oils. Antioxidant, antibacterial, antifungal, anti-helminthic, antiviral, hepatoprotective, immune-stimulatory, and antimicrobial properties are among the many pharmacological activity of P. africana preparations. They are also an abundant supplier of vital minerals and amino acids that support enzyme function and provide defense against the effects of oxidative stress. Using extracts from Prosopis africana is the way forward for effective chicken production, environmental sustainability and food hygiene.

Diatomaceous earth as insecticide: physiological and morphological evidence of its underlying mechanism.

Wheat grain containers or silos can be perfect habitats for insects, which generate large economic losses to grain production. Natural alternatives to synthetic insecticides have grown in popularity because of health, economic and ecological issues. Diatomaceous earth is a natural compound that has an insecticide effect by enhancing an insect's dehydration with no toxicity on mammals including humans. The aim of this study is to confirm the effect of diatomaceous earth as an insecticide for the wheat grain pest, the red flour beetle Tribolium castaneum (Coleoptera: Tenebrionidae) and demonstrate its underlying mechanisms as an insecticide by open-flow respirometry and scanning electron microscopy. Survival bioassays of T. castaneum revealed a dose-dependent insecticide effect of diatomaceous earth. Gravimetric measurements showed that 2 days exposure to diatomaceous earth produces a significant increase of mass loss. Open-flow respirometry measurements showed an increase of total water emission rate on insects due to an increase of both, respiratory and cuticular water loss. Our study revealed that diatomaceous earth produces an increase of insect's cuticle permeability, which is responsible for elevated cuticular water loss. Scanning electron microscopy images provided visual evidence of the lipid absorbent properties of diatomaceous earth particles, and showed a tendency for higher, although not significant, damaged area of the cuticle's surface from diatomaceous earth treated insects compared to control ones. With state-of-the art techniques like open-flow respirometry and scanning electron microscopy, we demonstrated the underlying mechanism of diatomaceous earth as an insecticide and provided new cues for understanding the properties of the cuticle and its ecological importance. © 2024 Society of Chemical Industry.

An Investigation of the Knowledge and Preferences of Parents About Dental Preventive Practices

Objective: Dental caries poses a significant health concern affecting, 60%-90% of children globally. While fluoride is widely utilized to prevent and eliminate dental caries, recent negative media coverage and concerns about irresponsible fluoride use have prompted a shift in parental perspectives. This study explores parental knowledge, preferences, and attitudes regarding preventive measures, with a focus on fluoride and potential natural or herbal alternatives. Methods: Our research was designed as a survey study. A survey form consisting of 11 questions was delivered to parents of children aged 6–14 years and presented to the Erciyes University Department of Pediatric Dentistry for examination or treatment were included in the study. A total of 300 parents participated in the study. Data was recorded as numbers and percentages. Results: Of the parents, 69% (207) reported that if they were offered natural herbal compounds instead of fluorinated varnish, they would prefer natural alternatives. A statistically significant relationship was found between the responses received from the parents about the effects of fluoride and the educational level of the parents (p&lt;0.05). Only 4 (1.3%) university graduate parents stated that fluoride had harmful effects. We found that 80.95% of the fathers and 68.39% of the mothers stated that they would prefer natural or herbal alternatives for their children instead of fluorinated varnish, and this was a statistically significant result (p&lt;0.05). Conclusion: Parents do not have sufficient knowledge and attitudes about preventive practices in oral dental health, and some parents still avoid the use of fluoride products. Therefore, there is a need to increase fluoride intake and its effects on children's health by educating parents or informing dentists.

Plant-Based Films and Hydrogels for Wound Healing.

Skin is constantly exposed to injury and infectious agents that can compromise its structural integrity and cause wounds. When this occurs, microorganisms from the skin microbiota and external bacteria and fungi can penetrate the wound and cause an infection, which complicates the healing process. Nowadays, there are several types of wound dressings available to treat wounds, some of which are incorporated with antimicrobial agents. However, the number of microorganisms resistant to these substances is rising. Therefore, the search for new, natural alternatives such as essential oils (EOs) and plant extracts (PEs) is on the rise. However, these substances present some limitations (poor bioavailability and poor target capacity), which limits their efficiency. Their incorporation in formulations in the form of films and hydrogels (HGs) can help to overcome these issues and may be a potential alternative to the current treatments. HGs and films incorporated with PEs and EOs have antimicrobial activity, promote the viability of skin cells and fibroblast migration, and are non-toxic and biocompatible. This review discusses the use of films and HGs for the topical delivery of EOs and PEs for wound treatment and their formulations as effective wound dressings, while debating some mechanisms and biological properties to elucidate their presumptive clinical relevance and possible applications.

Antimicrobial and Antiproliferative Effects of Zingiberaceae Oils: A Natural Solution for Oral Health.

Essential oils have been recognised for their potential benefits in oral care. The aim of this study was to evaluate the antibacterial and antiproliferative activity of essential oils derived from four Zingiberaceae species. A combination of GC/MS and GC-FID was employed to analyse these essential oils. The results showed that β-myrcene (79.77 %) followed by ethyl-cinnamate (40.14 %), β-curcumene (34.90 %), and alloaromadendrene (25.15 %) as the primary constituents of Curcuma mangga, Curcuma xanthorrhiza, Kaempferia galanga and Curcuma aeruginosa, respectively. The Zingiberaceae oils were tested for their antibacterial activity against oral bacteria using the disc diffusion test. Curcuma xanthorrhiza oil showed the largest inhibition zones against Streptococcus mitis (19.50±2.22 mm) and Streptococcus sanguinis (15.04±3.05 mm). Similarly, Curcuma mangga oil exhibited significant antibacterial activity against Streptococcus mutans (12.55±0.45 mm) and mixed oral bacteria (15.03±3.82 mm). Furthermore, the MTT viability assay revealed moderate inhibitory activity of these essential oils against H103 and ORL-204 oral cancer cells. The study findings demonstrate that Curcuma xanthorrhiza and Curcuma mangga essential oils have potent antibacterial properties, suggesting their potential use as natural alternatives to synthetic antibacterial agents in oral care products. However, further investigations are necessary to fully explore their therapeutic applications.
