Dietary encapsulated fennel seed (Foeniculum vulgare Mill.) essential oil supplementation improves performance, modifies the intestinal microflora, morphology, and transcriptome profile of broiler chickens.

Global antimicrobial resistance has led to a ban on the use of antibiotics as growth promoters (AGPs) in poultry farming, encouraging the use of natural phytogenic feed additives that provide similar effects to AGPs without causing resistance. The aim of this study was to determine the effects of the addition of encapsulated fennel seed (Foeniculum vulgare Mill.) essential oil (FEO) into the diets on the performance, intestinal microflora, morphology, and transcriptomic profiling of broiler chickens. In the study, 400 one-d-old male chicks of the Ross-308 genotype were randomly distributed into five groups, each with 16 replicates of five birds. The experiment included a control group fed on basal diets without the addition of FEO and treatment groups supplemented with 50 (FEO50), 100 (FEO100), 200 (FEO200), or 400 (FEO400) mg of encapsulated FEO/kg. Body weight and the European Production Efficiency Factor values were higher in the FEO100, FEO200, and FEO400 groups (P < 0.05). The feed conversion ratio significantly improved at all FEO levels (P < 0.05). FEO supplementation improved duodenum, jejunum, and ileum morphologies. It enhanced mucosal layer thickness in the duodenum and jejunum, and muscular layer thickness in the jejunum and ileum (P < 0.05). It also increased the number of Lactobacillus spp. in the jejunum and ileum (P < 0.05). According to the transcriptome profile obtained from the microarray analysis of samples taken from small intestine tissues, the mRNA expression levels of 261 genes in the FEO50 group (206 upregulated and 55 downregulated), 302 genes in the FEO100 group (218 upregulated and 84 downregulated), 292 genes in the FEO200 group (231 upregulated and 61 downregulated), and 348 genes in the FEO400 group (268 upregulated and 80 downregulated) changed compared to the control group. Most upregulated genes were associated with catalytic activity, binding, transcription regulators and transcription factors, anatomical structure and cellular development, and protein binding activity modulators. The downregulated genes mostly belonged to the transporter, carrier, and protein-modifying enzyme classes. Besides, the anti-inflammatory IL-10 gene (4.41-fold) increased significantly in the FEO100 group compared to the control group (P < 0.05). In conclusion, FEO improved the performance of broiler chickens by regulating biological processes such as performance and intestinal health, with the 100 mg FEO/kg supplementation being the most prominent.

The long-term use of low-level antibiotics in the poultry industry to promote growth, rather than for treatment, has led to the development of antimicrobial resistance (AMR), a significant risk to human and animal health. This concern has led to a ban on antibiotics as growth promoters (AGPs) in broiler diets, resulting in an increase in metabolic diseases in broiler chickens. Phytogenic feed additives have been tested as alternatives to compensate for the loss of AGPs. One such additive, fennel seed essential oil (FEO), known for its strong antimicrobial properties, was examined in this study for its impact on broiler growth performance and the underlying genetic and molecular mechanisms. The results showed that FEO enhanced feed conversion efficiency, thereby improving broiler performance. It positively affected the intestinal wall structure and function and helped establish a balanced microbiota by suppressing harmful and supporting beneficial microorganisms. Transcriptome datasets revealed that FEO modulated gene expression related to economically important traits such as performance and intestinal health. In conclusion, considering the urgent need for antibiotic-free production systems owing to escalating AMR and the growing interest in genotype-specific feeding in the postgenomic era, FEO may be a promising, natural, safe, and effective alternative to AGPs.

Profiling the chemical properties of Foeniculum vulgare Mill. and its flavonoids through comprehensive LC-MS/MS to evaluate their anti-motion sickness effect.

Foeniculum vulgare Mill. is a medicinal and food homologous plant, and it has various biological activities. Yet, no research has explored its anti-motion sickness effects. Chemical properties of fennel extracts (FvE) and flavonoids (Fvf) were analyzed based on UPLC-QTRAP-MS to elucidate its potential anti-motion sickness components in the present study. The mice models of motion sickness were stimulated by biaxial rotational acceleration. Behavioral experiments such as motion sickness index and open field test and the measurement of neurotransmitters were used to evaluate the efficacy of compounds on motion sickness. Results showed that FvE contains terpenes, alkaloids, flavonoids, etc. Eight flavonoids including quercetin-3ß-D-glucoside, rutin, hyperoside, quercetin, miquelianin, trifolin, isorhamnetin and kaempferol were identified in the purified Fvf. FvE and Fvf significantly reduced the motion sickness index of mice by 53.2% and 48.9%, respectively. Fvf also significantly alleviated the anxious behavior of mice after rotational stimulation. Among the eight flavonoids, isorhamnetin had the highest oral bioavailability and moderate drug-likeness index and thus speculated to be the bioactive compound in fennel for its anti-motion sickness effect. It reduced the release of 5-HT and Ach to alleviate the motion sickness response and improve the work completing ability of mice and nervous system dysfunction after rotational stimulation. This study provided in-depth understanding of the anti-motion sickness bioactive chemical properties of fennel and its flavonoids, which will contribute to the new development and utilization of fennel.

Influence of the Essential Oil of Foeniculum vulgare Mill. on Sunflower Oil during the Deep-frying Process of Chinese Maye.

Sunflower oil (SFO) is faced with serious oxidation problems during the deep-frying of Chinese Maye, and the search for natural antioxidants has become a focus of scientific research due to the potential toxicity of synthetic antioxidants. In the present study, the Foeniculum vulgare Mill. essential oil (FVEO), tert-butylhydroquinone (TBHQ) were added to SFO for a 30 h deep frying experiment and the results showed that FVEO added to sunflower oil at 1 g/kg was similar to that of TBHQ-0.01 g/kg, and FVEO-1.5 g/kg would promote the oxidation of SFO. FVEO to sunflower oil also prominently restrained the decrease of the sensory properties of the fried product, Chinese Maye, including appearance, taste, flavor and overall acceptance by 24.2%, 20.2%, 46.1% and 56.0% (p < 0.01 or p < 0.05), respectively. The results indicated that FVEO could be used as a natural antioxidant to replace TBHQ in the deep-frying process of SFO, but further research is needed on the key antioxidant constituent of FVEO.

Effect of supplementation of fennel seed powder on intake, growth performance, gut health and economics in goats.

The aim of this study was to evaluate the effect of fennel seed powder (FSP) at varying levels on intake, growth, gut health, body condition, body measurements and economics in post weaned male goats. For this experiment a total of 30 post weaned male kids of Barbari goats with statistically similar body weight (P = 0.575) and age (3-4 months) were randomly distributed in three comparable groups each having 10 kids. Three groups viz. control (no supplementation), T1 (0.5% of DM in diet) and T2 (1.0% of DM in diet) were formed and the study continued up to 5 months. Statistical analysis of results showed significant effect of FSP supplementation on intake, growth, body condition, and gut health and body measurements in goats of treatment groups. Significantly highest body weight (BW), average daily gain (ADG) and dry matter intake (DMI) (P < 0.001) was reported in T2 group, followed by T1 than control group goats. Further, feed conversion ratio (FCR), feed conversion efficiency (FCE%) and body condition score of treatment groups (T1 and T2) was improved significantly (P < 0.001) than control group goats. However, FCR and FCE% in T1 and T2 differed non- significantly (P > 0.05). Analysis of fecal samples indicated significantly higher (P < 0.001) fecal dry matter (FDM%), fecal consistency score (FS) in T1 and T2 group than control group whereas parasitic fecal egg count per gram (EPG) was significantly lower in T1 and T2 group than control group. However, EPG in T1 and T2 differed non- significantly (P > 0.05). Body measures differed significantly (P < 0.05) among groups. Economic evaluation of FSP supplemented showed that T1 and T2 group fetched INR 462 and 501 per goat on selling over control group (1USD = 82.54 INR). It can be concluded from this study that supplementation of FSP @ 1.0% of DM in diet may economically improve intake, growth, gut health, body condition, body measurements and economics in post weaned male Barbari goats.

Fennel affects porcine ovarian cell functions: The interrelationships with the environmental contaminant benzene.

The objective of this study was to examine the direct effects of the medicinal plant fennel on basic functions of ovarian cells, including proliferation, apoptosis, and release of progesterone and insulin-like growth factor I (IGFI), as well as to prevent the influence of the environmental contaminant benzene on these cells. Porcine ovarian granulosa cells were cultured with or without fennel extract alone or in combination with benzene. The expression of the proliferation marker PCNA and the apoptosis marker bax was analyzed by quantitative immunocytochemistry and enzyme-linked immunosorbent assay (ELISA). Fennel was able to promote proliferation and IGF-I release, but to suppress apoptosis and progesterone release. Benzene promoted the accumulation of both the proliferation and apoptosis markers, as well as IGF-I release, but it inhibited progesterone secretion. The presence of fennel did not prevent the effects of benzene on any of the measured parameters, while benzene prevented the effects of fennel on cell proliferation, apoptosis, and IGF-I but not progesterone output. These observations demonstrate the direct influence of fennel and benzene on basic ovarian cell functions. Furthermore, they show the inability of fennel to prevent the effects of benzene on these cells. On the other hand, the environmental contaminant benzene can block the response of ovarian cells to the medicinal plant fennel.

Seaweed extract and arbuscular mycorrhiza co-application affect the growth responses and essential oil composition of Foeniculum vulgare L.

The influence of arbuscular mycorrhiza fungi (AMF) inoculation, seaweed extract (SWE) foliar use, and their co-applications were evaluated on the growth-associated traits, antioxidant potential, essential oil profile, and the nutrients content of fennel plants. A factorial experiment was conducted as a completely randomized design with two factors and four replications in the greenhouse. The factors were: AMF inoculation (not inoculated and inoculated with 5 g kg-1) and SWE foliar application (0, 0.5, 1.5, or 3 g L-1). The highest root colonization percentage was recorded in plants treated with AMF + 3 g L-1 of SWE. The top recorded plant height, leaf number, leaf dry weight, biomass, thousand seed weight (TSW), total soluble proteins and total soluble carbohydrates content, antioxidant activity, and essential oil content belonged to AMF + 3 g L-1 of SWE. Furthermore, the co-application of AMF + SWE resulted in a considerable enhancement of the photosynthetic pigments content and, in N, P, K, Fe, Zn, and Mn contents in the shoots and roots. The GC-FID and GC-MS analysis revealed that (E)-anethole (73.28-76.18%), fenchone (5.94-8.26%), limonene (4.64-6.58%), methyl chavicol (2.91-3.18%), and (Z)-ß-ocimene (1.36-2.01%) were the principal essential oil constituents. The top (E)-anethole and fenchone contents were obtained by AMF + SWE. Altogether, the simultaneous application of AMF and SWE could be introduced as an environment-friendly strategy to reach reliable growth responses, especially in fennel plants' enriched with some precious essential oil constituents.

Characterization of potentially health-promoting constituents in sea fennel (Crithmum maritimum) cultivated in the Conero Natural Park (Marche region, Central Italy).

CONTEXT: Sea fennel (Crithmum maritimum L. [Apiaceae]) is an aromatic herb rich in bioactive molecules, such as polyphenols, with potential positive effects on human health. OBJECTIVE: This study aimed at the characterization of sea fennel secondary metabolites, focusing on the phenolic fraction. MATERIALS AND METHODS: Samples of whole sprouts, sole leaves and sole stems were subjected to accelerated solvent extraction with methanol, and the resulting extracts were analyzed by high­performance thin­layer chromatography, high-performance liquid chromatography, and liquid chromatography coupled with diode array detection and high-resolution mass spectrometry (LC-DAD-HRMS). RESULTS: HPTLC and HPLC analyses of sea fennel extracts showed similar chromatographic profiles among the tested samples, and the prevalence of chlorogenic acid within the phenolic fraction was verified. Ten hydroxycinnamic acids, including neochlorogenic acid, chlorogenic acid, cryptochlorogenic acid, isochlorogenic acid B, isochlorogenic acid A and isochlorogenic acid C, 11 flavonoid glycosides, e.g., rutin, hyperoside, isoquercitrin, two triterpene saponins and two hydroxylated fatty acids, were detected and annotated via liquid chromatography coupled with diode array detection and high-resolution mass spectrometry. DISCUSSION AND CONCLUSIONS: The use of accelerated solvent extraction and LC-DAD-HRMS for the characterization of sea fennel secondary metabolites allowed the annotation of seven compounds newly detected in sea fennel, including triterpene saponins and hydroxylated fatty acids.

Sea Fennel (Crithmum maritimum L.) as an Emerging Crop for the Manufacturing of Innovative Foods and Nutraceuticals.

Sea fennel (Crithmum maritimum L.) is a perennial, strongly aromatic herb that has been used since ancient times in cuisine and folk medicine due to its renowned properties. Recently described as a "cash" crop, sea fennel is an ideal candidate for the promotion of halophyte agriculture in the Mediterranean basin due to its acknowledged adaptation to the Mediterranean climate, its resilience to risks/shocks related to climate changes, and its exploitability in food and non-food applications, which generates an alternative source of employment in rural areas. The present review provides insight into the nutritional and functional traits of this new crop as well as its exploitation in innovative food and nutraceutical applications. Various previous studies have fully demonstrated the high biological and nutritional potential of sea fennel, highlighting its high content of bioactive compounds, including polyphenols, carotenoids, ω-3 and ω-6 essential fatty acids, minerals, vitamins, and essential oils. Moreover, in previous studies, this aromatic halophyte showed good potential for application in the manufacturing of high-value foods, including both fermented and unfermented preserves, sauces, powders, and spices, herbal infusions and decoctions, and even edible films, as well as nutraceuticals. Further research efforts are needed to fully disclose the potential of this halophyte in view of its full exploitation by the food and nutraceutical industries.

Evaluation of the Anti-Metastatic Effect of Foeniculum Vulgare on the Protein Expression of HSP 70 & 90 in Balb/c Mice with 4t1 Model of Breast Cancer.

INTRODUCTION: Breast cancer is one of the important factors of cancer-related deaths. Considering the drug resistance, special attention has been paid to natural compounds. This study aimed at evaluating the anti-metastatic activity of fennel in a breast cancer mouse model. METHODS: A total of 35 adult female BALB/C mice were used in this study. Breast cancer was induced by subcutaneous injection of 4T1 cells in the right lower flank. The mice received fennel extracts daily via intraperitoneal injection for two weeks. Meanwhile, tumor volume was measured every day using calipers. After two weeks, each animal was anesthetized. The protein expression of HSP 70 & 90 was measured in liver tissue and ovary. The expression of her2 was measured in tumor tissue. The activity of Glutathione peroxidase and reductase as anti-oxidant agents were measured in serum. RESULTS: Tumor size significantly decreased after nine days' treatment of the fennel. The expression of HER2 increased in the tumor tissue and decrease with different dose of fennel. Fennel treatment caused a decrease in the protein expression of HSP 70 & 90 in the liver tissues. CONCLUSION: Based on our findings, fennel has anti-tumor and anti-metastatic activities against aggressive cancers.

Ginkgo, fennel, and flaxseed can affect hormone release by porcine ovarian cells and modulate the effect of toluene.

Experimental studies have documented the toxic effects of toluene on the mammalian female reproductive processes. The aim of this in vitro study was to examine the potential of functional food plant extracts, namely, of ginkgo, fennel, and flaxseed, in modifying the toluene-induced effects on ovarian hormone release. Porcine granulosa cells were incubated with ginkgo, fennel, or flaxseed extracts (0, 1, 10, or 100 µg/mL) and/or toluene (10 µg/mL). Enzyme immunoassays were used in order to measure the release of progesterone (P), oxytocin (OT), and prostaglandin F (PGF) in the culture media. Toluene suppressed the release of P and enhanced the release of OT and PGF. All tested plant extracts reduced P and increased OT release, while the PGF output was found inhibited by ginkgo and stimulated by fennel and flaxseed. When the cells were incubated with toluene and each one of the plant extracts, toluene was able to prevent their action on P release, as well as those of fennel and flaxseed on OT and PGF release. Moreover, ginkgo enhanced but fennel or flaxseed prevented the toluene-induced effects on OT and PGF release. These observations (i) document novel aspects of the toluene-induced toxicity; (ii) demonstrate the direct influence of ginkgo, fennel, and flaxseed extracts on the ovarian secretory activity; (iii) inform our understanding of the interrelationship between toluene and the tested plant extracts with regard to their effects on ovarian hormone release; (iiii) demonstrate the ability of fennel and flaxseed to prevent adverse effect of toluene on ovarian hormones.

FEMA GRAS assessment of natural flavor complexes: Allspice, anise, fennel-derived and related flavoring ingredients.

The FEMA Expert Panel program to re-evaluate the safety of natural flavor complexes (NFCs) used as flavoring ingredients in food has resulted in the publication of an updated constituent-based procedure as well as publications on the safety evaluation of many botanical-derived NFCs. This publication, ninth in the series and related to the ninth publication, describes the affirmation of the generally recognized as safe (GRAS) status for NFCs with propenylhydroxybenzene and allylalkoxybenzene constituents under their conditions of intended use as flavoring ingredients added to food. The Panel's procedure applies the threshold of toxicological concern (TTC) concept and evaluates relevant data on absorption, metabolism, genotoxic potential and toxicology for the NFCs themselves and their respective constituent congeneric groups. For NFCs containing allylalkoxybenzene constituent(s) with suspected genotoxic potential, the estimated intake of the individual constituent is compared to the TTC for compounds with structural alerts for genotoxicity and if exceeded, a margin of exposure is calculated using BMDL10 values derived from benchmark dose analyses using Bayesian model averaging, as presented in the tenth article of the series. Safety evaluations for NFCs derived from allspice, anise seed, star anise, sweet fennel seed and pimento leaves were conducted and their GRAS status was affirmed for use as flavoring ingredients. The scope of the safety evaluation contained herein does not include added use in dietary supplements or any products other than food.

In utero and postnatal exposure to Foeniculum vulgare and Linum usitatissimum seed extracts: modifications of key enzymes involved in epigenetic regulation and estrogen receptors expression in the offspring's ovaries of NMRI mice.

BACKGROUND: Early-life exposure to exogenous estrogens such as phytoestrogens (plant-derived estrogens) could affect later health through epigenetic modifications. Foeniculum vulgare (fennel) and Linum usitatissimum (flax) are two common medicinal plants with high phytoestrogen content. Considering the developmental epigenetic programming effect of phytoestrogens, the main goal of the present study was to evaluate the perinatal exposure with life-long exposure to hydroalcoholic extracts of both plants on offspring's ovarian epigenetic changes and estrogen receptors (ESRs) expression level as signaling cascades triggers of phytoestrogens. METHODS: Pregnant mice were randomly divided into control (CTL) that received no treatment and extract-treated groups that received 500 mg/kg/day of fennel (FV) and flaxseed (FX) alone or in combination (FV + FX) during gestation and lactation. At weaning, female offspring exposed to extracts prenatally remained on the maternal-doses diets until puberty. Then, the ovaries were collected for morphometric studies and quantitative real-time PCR analysis. RESULTS: A reduction in mRNA transcripts of the epigenetic modifying enzymes DNMTs and HDACs as well as estrogen receptors was observed in the FV and FX groups compared to the CTL group. Interestingly, an increase in ESRα/ESRß ratio along with HDAC2 overexpression was observed in the FV + FX group. CONCLUSION: Our findings clearly show a positive relationship between pre and postnatal exposure to fennel and flaxseed extracts, ovarian epigenetic changes, and estrogen receptors expression, which may affect the estrogen signaling pathway. However, due to the high phytoestrogen contents of these extracts, the use of these plants in humans requires more detailed investigations.

Bridging the Chemical Profile and Biological Activities of a New Variety of Agastache foeniculum (Pursh) Kuntze Extracts and Essential Oil.

This study investigated the phytochemical content of alcoholic extracts and essential oil of a new variety of medicinal plants, Agastache foeniculum (Pursh), which Kuntze adapted for cultivation in Romania, namely "Aromat de Buzau". The essential oil was investigated by GC-MS, while the identification and quantification of various compounds from alcoholic extracts were performed by HPLC-DAD. The total phenol and flavonoid contents of the extracts were evaluated by using standard phytochemical methods. The antioxidant activities of ethanol, methanol extracts, and essential oil of the plant were also assessed against 2,2'-diphenyl-1-picrylhydrazyl (DPPH•), 2,2'-azino-bis-(3-ethylbenzothiazoline-6-sulphonic acid) (ABTS•+), and by ferric reducing power (FRAP) using spectroscopic methods. Cyclic voltammetry was used to evaluate the antioxidant capacity of the essential oil. The concentrations of phenolic compounds were higher in methanolic extract compared to ethanolic extract. A significant correlation was found between total phenol and total flavonoid contents (r = 0.9087). Significant high correlations were also found between the total phenolic compounds and the antioxidant activities of the extracts (r ≥ 0.8600, p < 0.05). In addition, the extracts and essential oil showed good antioxidant and xanthine oxidase inhibitory activities. Estragole was detected as the major constituent of the essential oil (94.89%). The cytotoxic activity of the essential oil was evaluated by the MTT assay. At lower concentrations (1 µg/mL) high cytotoxicity against MCF-7 breast cancer cells was observed but not on the non-tumoral dermal fibroblasts (HDF) which indicated selectivity for cancer cells and suggests the presence of biologically active components that contribute to the observed high cytotoxic effect. Findings from the present study offer new perspectives on the use of A. foeniculum as a potential source of bioactive compounds and a good candidate for pharmaceutical plant-based products.

A Comparative UHPLC-Q-Trap-MS/MS-Based Metabolomics Analysis to Distinguish Foeniculum vulgare Cultivars' Antioxidant Extracts.

Among the environmental factors, seasonality is the one which most affects the metabolome of a plant. Depending on the harvest season, the plant may have a variable content of certain metabolites and thus may have different biological properties. Foeniculum vulgare is an annual plant whose cultivation creates large amounts of waste rich in bioactive compounds. The present investigation was performed with the aim of determining the amount of biologically active compounds in F. vulgare wastes obtained from varieties of different seasonality. Ten polyphenolic compounds were quantified in the little stems and leaves of Tiziano, Pegaso, and Preludio cultivars by ultra performance liquid chromatography (UPLC) hyphenated to QTRAP mass spectrometry by using the MRM (multiple reaction monitoring) method. The antioxidant activity of hydroalcoholic extracts was then evaluated using TEAC and DPPH spectrophotometric assays, followed by a multivariate statistical analysis to determine the correlation between metabolite expression and antioxidant activity. The Preludio variety, grown in summer, showed a higher content of bioactive compounds, which guarantees it a better antioxidant power; kaempferol 3-O-glucuronide, quercetin 3-O-glucuronide, and quercetin 3-O-glucoside are the polyphenolic compounds that could be mainly responsible for the antioxidant effect of fennel. The PLS chemometric model, which correlated quantitative data obtained by a sensitive and selective LC-ESI-QTrap-MS/MS analysis of antioxidant activity, resulted in a selective tool to detect the compounds responsible for the activity shown by the extracts in chemical tests.

Targeting Y220C mutated p53 by Foeniculum vulgare-derived phytochemicals as cancer therapeutics.

CONTEXT: The mutations in the TP53 gene are the most frequent (50-60% of human cancer) genetic alterations in cancer cells, indicating the critical role of wild-type p53 in the regulation of cell proliferation and apoptosis upon oncogenic stress. Most missense mutations are clustered in the DNA-binding core domain, disrupting DNA binding ability. However, some mutations like Y220C occur outside the DNA binding domain and are associated with p53 structure destabilization. Overall, the results of these mutations are single amino acid substitutions in p53 and the production of dysfunctional p53 protein in large amounts, consequently allowing the escape of apoptosis and rapid progression of tumor growth. Thus, therapeutic targeting of mutant p53 in tumors to restore its wild-type tumor suppression activity has immense potential for translational cancer research. Various molecules have been discovered with modern scientific techniques to reactivate mutant p53 by reverting structural changes and/or DNA binding ability. These compounds include small molecules, various peptides, and phytochemicals. TP53 protein is long thought of as a potential target; however, its translation for therapeutic purposes is still in its infancy. The study comprehensively analyzed the therapeutic potential of small phytochemicals from Foeniculum vulgare (Fennel) with drug-likeness and capability to reactivate mutant p53 (Y220C) through molecular docking simulation. The docking study and the stable molecular dynamic simulations revealed juglalin (- 8.6 kcal/mol), retinol (- 9.14 kcal/mol), and 3-nitrofluoranthene (- 8.43 kcal/mol) significantly bind to the mutated site suggesting the possibility of drug designing against the Y220C mutp53. The study supports these compounds for further animal based in vivo and in vitro research to validate their efficacy. METHODS: For the purposes of drug repurposing, recently in-silico methods have presented with opportunity to rule out many compounds which have less probability to act as a drug based on their structural moiety and interaction with the target macromolecule. The study here utilizes molecular docking via Autodock 4.2.6 and molecular dynamics using Schrodinger 2021 to find potential therapeutic options which are capable to reactive the mutated TP53 protein.

Binary Synergistic Combinations of Lavender and Fennel Essential Oils with Amoxicillin.

Microbial resistance is an important problem in modern healthcare systems. In addition to drug resistance, the side effects of current antibiotic applications are also known issues. In this present study, binary combinations of amoxicillin with European Pharmacopoeia quality lavender (Lavandula angustifolia) and fennel (Foeniculum vulgare) essential oils were evaluated against human pathogenic microbial strains. The checkerboard method was used to quantify the efficacy of the essential oils in combination with amoxicillin. As an initial result, remarkable in vitro antimicrobial activity was observed at relatively low amoxicillin concentrations using different oil combinations against Staphylococcus aureus ATCC 6538, Enterococcus faecalis ATCC 29212, Bacillus cereus ATCC 14579, Escherichia coli NRRL B-3008, Salmonella typhi (clinical isolate), respectively. Fractional inhibitory concentrations were calculated and interpreted in terms of addition, synergy, antagonism, or indifferent. A synergistic interaction with the combination F. vulgare essential oil and amoxicillin (fractional inhibitory concentration index = 8.05 × 10-4) was observed against the pathogens E. faecalis and Escherichia coli. Both essential oils together and in combination with amoxicillin showed a synergistic effect with possible future applications.

Characterization of fennel germplasm for physiological persistence and drought recovery: Association with biochemical properties.

In the perennial medicinal plant fennel (Foeniculum vulgare), persistence over years, production stability, and successful post-drought recovery are as important as plant productivity. Characterization of productivity, post-drought recovery, persistency and their association with phytochemical properties has not yet been performed in fennel. In this study, 64 fennel genotypes (from 23 different countries) from four subspecies/varieties including F. vulgare ssp. piperitum, F. vulgare var. vulgare and F. vulgare var. dulce and F. vulgare var. azoricum were evaluated in the field over four years (2015-2018), then was assessed for post-drought recovery over the next two years (2019-2020). High genotypic variation was observed among genotypes and subspecies. Based on the GC-MS analysis, trans-anethole (22.4-90.6%), estragole (2.1-25.8%), fenchone (4.9-19.8%), and limonene (0.5-11.9%) are major components in the essential oils of the studied germplasm. The highest persistence and the lowest average post-drought recovery belonged to ssp. piperitum. This subspecies also had the highest amount of limonene, fenchone, and estragole and the lowest amount of trans-anethole compared to other subspecies. The highest essential oil content and stability was observed in var. dulce. Seed yield and persistence were found to be negatively associated, suggesting that selection for more productivity may indirectly promote less persistent genotypes. Post-drought recovery was negatively associated with two main phytochemical compounds of essential oil, fenchone and estragole, but positively associated with trans-anethole. Persistence had negative correlation with estragole content. Results indicated that indirect selection for post-drought recovery and persistence may be possible through selection for phytochemical properties. The negative correlation between some essential oil components may indicate that some are isomers, which can limit the ability to select for certain combinations. Superior genotypes identified in this study can be used to construct populations for future studies and as parents of crosses to develop new varieties.

Development of mouse model for oral allergy syndrome to identify IgE cross-reactive pollen and food allergens: ragweed pollen cross-reacts with fennel and black pepper.

Oral allergy syndrome (OAS) is an IgE-mediated immediate food allergy that is localized to the oral mucosa. Pollen food allergy syndrome (PFAS), a pollinosis-associated OAS, is caused by cross-reactivity between food and pollen allergens. However, we need to more precisely understand the underlying pathogenesis of OAS/PFAS. In the present study, we developed a method to comprehensively identify cross-reactive allergens by using murine model of OAS and protein microarray technology. We focused on lip angioedema, which is one of the most common symptoms of OAS, and confirmed that mast cells reside in the tissues inside the lower lip of the mice. Interestingly, when the food allergen ovalbumin (OVA) was injected inside the lower lip of mice with high levels of OVA-specific IgE followed by an intravenous injection of the Evans blue dye, we found immediate dye extravasation in the skin of the neck in a mast cell-dependent manner. In addition, the degree of mast cell degranulation in the oral cavity, reflecting the severity of oral allergic responses, can be estimated by measuring the amount of extravasated dye in the skin. Therefore, we used this model of OAS to examine IgE cross-reactive allergens in vivo. Protein microarray analysis showed that serum IgE from mice intraperitoneally sensitized with ragweed pollen, one of the major pollens causing pollinosis, bound highly to protein extracts from several edible plants including black peppercorn and fennel. We confirmed that the levels of black pepper-specific IgE and fennel-specific IgE were significantly higher in the serum from ragweed pollen-sensitized mice than in the serum from non-sensitized control mice. Importantly, analysis of murine model of OAS showed that the injection of black pepper or fennel extract induced apparent oral allergic responses in ragweed pollen-sensitized mice. These results indicate IgE cross-reactivity of ragweed pollen with black pepper and fennel. In conclusion, we developed mouse model of OAS to identify IgE cross-reactive pollen and food allergens, which will help understand the pathogenesis of OAS/PFAS.
