Evaluation of Antimicrobial Activity of Selected Plant Extracts against Staphylococcus Strains Isolated from Wound Infections.

Wound infections are a significant medical problem, with Staphylococcus species being one of the most common etiological factors. Treatment is complex due to bacterial antibiotic resistance and the ability to form a biofilm. The aim of this study was to determine the drug susceptibility of the clinical isolates of Staphylococcus species obtained from wound infections, assess their ability to form a biofilm in vitro, evaluate the level of extracellular slime synthesis, and test the antistaphylococcal properties of selected plant extracts against plate-cultured bacteria and activity against mature biofilms. A total of 20 Staphylococcus strains were evaluated. The antibiotic susceptibility and sensitivity of the strains to the tested extracts were determined using the disc diffusion method. The production of extracellular bacterial slime was assessed using Congo Red agar plates. The biofilm formation and the effect of plant extracts on the biofilm layer were examined using the MTT method on polystyrene microtiter plates. Diverse drug susceptibility profiles, slime production ability, and in vitro biofilm formation were observed among the tested strains. It was found that aqueous extracts from the Serpylli herba, Arctii lappae folium, Taraxaci folium, and Galii aparini herba showed antibacterial activity against some of the tested strains. In contrast, their antibiofilm activity was not confirmed. Among all tested preparations, the most promising antimicrobial extracts in both planktonic cultures and biofilm were Thymus serpyllum herb and Taraxacum officinale leaf extracts. These results allowed us to conclude their potential application in medicine to support the treatment of challenging wound conditions.

Chemical analysis of Alliin-Rich Allium sativum (Garlic) extract and its safety evaluation in Drosophila melanogaster

Garlic (Allium sativum) has been traditionally valued for its medicinal properties attributed to the presence of organosulfur compounds. Despite its benefits, concerns about herbal extract toxicity have arisen, necessitating safety assessment. This study was designed to evaluate the chemical analysis and safety profile of Alliin-Rich Garlic Extract (ARGE) using Drosophila melanogaster as a model organism. The ARGE was extracted from garlic cloves (Allium sativum Linn: UIH-23262) using a microwave-assisted method and characterized using UPLC-ESI-MS, 1H NMR, HPLC and IR. Its safety evaluation was determined using D. melanogaster (Harwich strain), and various assays were conducted on 1–3-day-old flies. Toxicological markers and oxidative stress were assessed to understand the impact of ARGE on the flies. Chemical profiling of ARGE using UPLC-ESI-MS, confirmed the presence of alliin (S-ally-L-cysteine-S-oxide), L-arginine, γ-glutamylmethionine, S-(2-carboxypropyl) glutathione, N-γ-glutamyl-S-(1-propenyl) cysteine, N-γ-glutamyl-S-(2-propenyl) cysteine, N-γ-glutamylphenylalanine, S-(allylthio) cysteine, γ-glutamyl-S-allylthiocysteine and eruboside B. HPLC confirmed an alliin content of 0.073 mg/g. Toxicological assessment in D. melanogaster revealed that ARGE enhanced antioxidant defenses by increasing total thiol levels and GST activity, while reducing acetylcholinesterase activity. No significant alteration was observed in catalase activity and cellular metabolic rate. Histological examination revealed no alterations in the histoarchitecture of the brain, fat body or gut of D. melanogaster. The study demonstrated the safety of ARGE in D. melanogaster, supporting its potential as a safe herbal remedy.

Simple ROS-responsive micelles loaded Shikonin for efficient ovarian cancer targeting therapy by disrupting intracellular redox homeostasis

Ovarian cancer is the most common malignant tumor in women. Shikonin (SHK), an herbal extract from Chinese medicine, shows promise in treating ovarian cancer by inducing reactive oxygen species (ROS). However, its clinical use is limited by poor tumor targeting and low bioavailability, and its therapeutic potential is further compromised by the elevated levels of antioxidants such as glutathione (GSH) within tumor cells. In this study, a novel formulation of ROS-responsive micelles loaded with SHK was developed using hyaluronic acid-phenylboronic acid pinacol ester conjugation (HA-PBAP) for targeted therapy of ovarian cancer through disruption of intracellular redox homeostasis. The SHK@HA-PBAP exhibits targeted delivery to ovarian cancer cells through the interaction between HA and CD44 receptors. Upon internalization by cancer cells, the high levels of intracellular ROS triggered the degradation of SHK@HA-PBAP and simultaneously released SHK and generated GSH scavenger quinone methide (QM). The SHK and QM released from the SHK@HA-PBAP effectively induce the production of ROS and deplete intracellular GSH, leading to the disruption of intracellular redox homeostasis and subsequent induction of cell death. These characteristics collectively inhibit the growth of ovarian cancer. In vitro and in vivo studies have demonstrated that SHK@HA-PBAP micelles exhibit superior antitumor efficacy compared to free SHK in both A2780 cells and A2780 tumor-bearing mice. The ROS-responsive SHK@HA-PBA presents a promising therapeutic approach for the treatment of ovarian cancer.

The effect of the Fitostemin-WP® biostimulator on yield and quality characteristics of rice (Oryza sativa L.)

In order to avoid yield and quality reduction of rice, it is essential to provide nutrition rice plants require. Therefore, a field experiment was conducted at the research area of the Institute of Agriculture - Skopje, Department of Field Crops, Ss. Cyril and Methodius University in Skopje, Republic of Macedonia, in Kochani, a rice production region. The experiment was set up to determine the effects of the Fitostemin-WP® biostimulator on some yield and quality properties of an Italian rice variety Opale during the vegetative seasons in 2020 and 2021. Standard agrotechnical methods for crop production were applied. Fitostemin-WP® is an herbal product in the form of powder and it consists of herbal extracts and minerals. It is used for increasing crop yield. The field experiment was arranged in a Zade method with a Fitostemin-WP® treatment and a control one in 3 replications. Only basic fertilizers (350kg/ha NPK and 200kg/ha Urea (46% N)) were applied on the control plot, while the treatment plot, besides basic fertilization, was also treated with Fitostemin-WP® with 100 g/ha dosage once during the vegetation period (tillering stage). The following parameters were examined in this study, namely the biological, grain and straw yield, the number of productive tillers/m2, panicle weight, and milling fractions. Results were analyzed with the ANOVA and LSD test. According to the results from this study, statistically significant differences were not found in these two years of field experiments for the examined parameters. However, the values for the brokens have shown some significant differences between the years, but not between the treatment and the control. This can result from the environmental impact during the vegetative period. More frequent usage of Fitostemin-WP® during the vegetation period of the rice plant may show more significant results.

The Essential Role of Herbal-based Therapies in Combatting Acne Vulgaris

Inflammation, follicular epidermal hyperproliferation, and Propionibacterium acnes (P. acnes) are the primary causes of acne vulgaris, a prevalent skin condition that affects millions of young adults and adolescents. This intricate pathophysiology leads to various acne symptoms, such as whiteheads and blackheads, inflammatory nodules, and scarring. Among the many traditional allopathic acne therapies that often have serious side effects include hormone therapy, hydroxy acids, oral and topical antibiotics, retinoic acid derivatives, and acne medications. Herbal extracts are becoming more and more well-liked as more holistic, kinder substitutes with fewer side effects. Herbal extracts with antibacterial, anti-inflammatory, and antioxidant qualities include Eucalyptus Globulus, Thymus vulgaris (thyme), Melaleuca alternifolia (tea tree), Lavandula angustifolia (lavender), Origanum vulgare (oregano), and Curcuma longa (turmeric). Because of these qualities, they are considered to be viable candidates for treating different elements of acne etiology, including wound healing, inflammation reduction, and P. acnes growth inhibition. Developing herbal remedies is a viable approach to developing efficient and minimally invasive acne treatments. Medicinal plants and essential oils have a long history of traditional use and the potential to attenuate harmful exposures and lessen drug-induced side effects. Their use in dermatological treatments demonstrates their ability to offer comprehensive and natural solutions for the treatment of acne vulgaris, a common and frequently upsetting skin condition.

Punicalagin as a novel selective aryl hydrocarbon receptor (AhR) modulator upregulates AhR expression through the PDK1/p90RSK/AP-1 pathway to promote the anti-inflammatory response and bactericidal activity of macrophages

Aryl hydrocarbon receptor (AhR) plays an important role in inflammation and immunity as a new therapeutic target for infectious disease and sepsis. Punicalagin (PUN) is a Chinese herbal monomer extract of pomegranate peel that has beneficial anti-inflammatory, antioxidant and anti-infective effects. However, whether PUN is a ligand of AhR, its effect on AhR expression, and its signaling pathway remain poorly understood. In this study, we found that PUN was a unique polyphenolic compound that upregulated AhR expression at the transcriptional level, and regulated the AhR nongenomic pathway. AhR expression in lipopolysaccharide-induced macrophages was upregulated by PUN in vitro and in vivo in a time- and dose-dependent manner. Using specific inhibitors and siRNA, induction of AhR by PUN depended on sequential phosphorylation of 90-kDa ribosomal S6 kinase (p90RSK), which was activated by the mitogen-activated protein kinase kinase (MEK)/extracellular signal-regulated kinase (ERK) and phosphoinositide-dependent protein kinase (PDK)1 pathways. PUN promoted p90RSK-mediated activator protein-1 (AP-1) activation. AhR knockout or inhibitors reversed suppression of interleukin (IL)-6 and IL-1β expression by PUN. PUN decreased Listeria load and increased macrophage survival via AhR upregulation. In conclusion, we identified PUN as a novel selective AhR modulator involved in AhR expression via the MEK/ERK and PDK1 pathways targeting p90RSK/AP-1 in inflammatory macrophages, which inhibited macrophage inflammation and promoted bactericidal activity.

Phytotherapy as an alternative approach in oral candidiasis management: A systematic review protocol

Background Conventional antifungal therapies, including topical applications, are effective against oral candidiasis but have limitations such as resistance development and cytotoxicity especially for immunocompromised patients. Phytotherapy presents a promising alternative, offering potential solutions to these challenges. However, despite numerous clinical trials, there is a lack of standardized protocols for phytotherapeutic applications. This systematic review protocol seeks to evaluate the potential of phytotherapy as an alternative treatment for oral candidiasis and compare its efficacy with standard antifungal therapies. Protocol This protocol aims to assess the effectiveness of phytotherapy compared to standard antifungal treatments for oral candidiasis. Initially, controlled descriptors in MeSH terms (e.g., “Candidiasis, Oral,” “Phytotherapy”) and keywords were selected from MEDLINE and combined using Boolean operators (‘AND’, ‘OR’) to create a comprehensive search strategy. Titles and abstracts will be screened by two independent reviewers to select studies that meet the inclusion criteria. The quality and risk of bias of the selected studies will be assessed afterward. Data will be gathered using standardized tools and subsequently synthesized for analysis. Discrepancies between reviewers will be settled through discussion, or, if required, by involving a third reviewer. Discussion Results obtained from this systematic review will describe various natural compounds like essential oils, herbal extracts, and bioactive plant ingredients that exhibit antifungal properties used against oral candidiasis and will evaluate their effectiveness in comparison to standard antifungal treatments.

Influence of oil base and gelling agent on the performance of oil gels

Abstract Oil gels, as a novel delivery system, have broad prospects in carrying nutrients and active substances. It has been found that the properties of oil gels are closely related to the types of oil bases and gelling agents used. In this study, soybean oil, sesame oil, and coconut oil were used as oil bases, while ethyl cellulose (EC), monoglycerides (MG), herbal extracts (HE), and hydroxypropyl methylcellulose-xanthan gum (HPMC-XG) were used as gelling agents to prepare different oil gels. The performance of the oil gels was evaluated based on appearance, microstructure, viscosity, oil-holding capacity, and drug-loading capability.

Valtrate Suppresses TNFSF14-Mediated Arrhythmia After Myocardial Ischemia-Reperfusion by Inducing N-linked Glycosylation of LTβR to Regulate MGA/MAX/c-Myc/Cx43.

Myocardial ischemia-reperfusion (MIR)-induced arrhythmia remains a major cause of death in patients with cardiovascular diseases. The reduction of Cx43 has been known as a major inducer of arrhythmias after MIR, but the reason for the reduction of Cx43 remains largely unknown. The aim of this study was to find the key mechanism underlying the reduction of Cx43 after MIR and to screen out an herbal extract to attenuate arrhythmia after MIR. The differentially expressed genes in the peripheral blood mononuclear cell (PBMCs) after MIR were analyzed using the data from several gene expression omnibus data sets, followed by the identification in PBMCs and the serum of patients with myocardial infarction. Tumor necrosis factor superfamily protein 14 (TNFSF14) was increased in PBMCs and the serum of patients, which might be associated with the injury after MIR. The toxic effects of TNFSF14 on cardiomyocytes were investigated in vitro . Valtrate was screened out from several herbal extracts. Its protection against TNFSF14-induced injury was evaluated in cardiomyocytes and animal models with MIR. Recombinant TNFSF14 protein not only suppressed the viability of cardiomyocytes but also decreased Cx43 by stimulating the receptor LTβR. LTβR induces the competitive binding of MAX to MGA rather than the transcriptional factor c-Myc, thereby suppressing c-Myc-mediated transcription of Cx43. Valtrate promoted the N-linked glycosylation modification of LTβR, which reversed TNFSF14-induced reduction of Cx43 and attenuated arrhythmia after MIR. In all, valtrate suppresses TNFSF14-induced reduction of Cx43, thereby attenuating arrhythmia after MIR.

Lygodium microphyllum Inhibits de Novo Lipogenesis Activity in the Hepatocytes of High-Fat High-Fructose-Induced Rats by Increasing the Levels of SIRT1 and AMPK.

The prevalence of non-alcoholic fatty liver disease (NAFLD) is currently of great concern due to its risk of developing T2DM and cardiovascular disease. The development of NAFLD may be initiated by de novo lipogenesis in the hepatocytes. Sirtuin1 (SIRT1) and adenosine monophosphate-activated protein kinase (AMPK), are responsible for the lipogenesis mechanism. Interestingly, plant sterols, such as beta-sitosterol and stigmasterol, have the potential to lower the LDL-cholesterol in dyslipidemic patients. Beta-sitosterol was present in the ethanol extract of Lygodium microphyllum herbs at a concentration of 283.55µg/g extract. This sterol interacted with the active allosteric-binding site of SIRT1 and AMPK similarly to the proteins' activators. To investigate the anti-lipogenesis activity of the ethanol extract of L. microphyllum (ELM) in the liver tissue of rats through the SIRT1 and AMPK levels. Forty male Wistar rats were used in this study: (1) normal control group; (2) high-fat high-fructose diet (HFHFD) rats; (3) HFHFD rats treated with metformin; (4) HFHFD rats treated with resveratrol; (5) HFHFD rats treated with beta-sitosterol; (6-8) HFHFD rats treated with ELM doses of 200, 400, and 600 mg/kg BW. Rats in the normal control group were fed regular chow, while other groups of rats were given HFHFD for 35 days. All drugs were given orally on D15 till D35. On D35, the rats were sacrificed, and the liver organs were examined for the liver index, morphology, NAFLD activity score (NAS), and levels of SIRT1 and AMPK. ELM improves the morphology, the liver index, the steatosis condition, and the NAS of HFHFD-induced NAFLD rats. ELM increases the levels of SIRT1 and AMPK in the liver tissue of HFHFD-induced NAFLD rats. ELM may have the potential to inhibit de novo lipogenesis by increasing the levels of SIRT1 and AMPK.

Fabrication of highly flexible biopolymeric chitosan/agarose based bioscaffold with Matricaria recutita herbal extract for antimicrobial wound dressing applications

A flexible biopolymer-based antimicrobial wound dressing has the potential to alleviate the burden of bacterial infections in wounds by enhancing antimicrobial effectiveness and promoting faster wound healing. This study focuses on the development of a highly flexible chitosan-agarose (CS-AG) bioscaffold, incorporating Matricaria recutita chamomile flower extract (CH) through a conventional casting method. The flexible CS-AG bioscaffold's physiochemical properties were confirmed by FTIR, indicating secondary interactions, and XRD, showing its crystalline structure. The addition of CH to the optimized CS-AG bioscaffold resulted in significant tensile strength (17.28 ± 0.33 MPa), distinctive structural morphology (SEM), surface roughness (AFM), contact angle, improved thermal properties (DSC), and enhanced thermal stability (TGA). Furthermore, the CH-infused bioscaffold significantly increased swelling capacity (~81.09 ± 1.74 % over 48 h), and degradation profile (~52 % over 180 h). The release studies of CS-AG-CH bioscaffold demonstrate controlled release of CH with in the bioscaffold at different pH conditions. The bioscaffold demonstrated effective antibacterial activity against S. aureus and E. coli strains. Additionally, cytotoxicity assays indicated that the bioscaffold supports better cell viability and proliferation in fibroblast (NIH 3T3) cell lines. Consequently, this antimicrobial bioscaffold shows promise as a drug release system and biocompatible wound dressing suitable for tissue engineering applications.

Antihyperglycemic activity of a novel polyherbal formula (HF344), a mixture of fifteen herb extracts, for the management of type 2 diabetes: Evidence from in vitro, ex vivo, and in vivo studies

Antihyperglycemic effects of a novel polyherbal formula (HF344), comprising fifteen Thai herbal extracts, were elucidated for pharmacological mechanisms and potential for managing type 2 diabetes mellitus, by employing in vitro, ex vivo, and in vivo approaches. LC/MS analysis of HF344 extract revealed several phytoconstituents, with piperine identified as the major active compound. HF344 extract significantly enhanced insulin secretion in RINm5F cells in vitro and inhibited glucose uptake into the everted sacs of the mouse small intestine ex vivo in a concentration-dependent manner compared to the control (p < 0.05). It exhibited potent α-glucosidase inhibition in vitro, with an IC50 of 96.74 μg/mL. Moreover, HF344 extract upregulated mRNA levels of GLUT1 in L6 skeletal myoblasts, suggesting increased glucose uptake into skeletal muscle. In addition, in vivo antihyperglycemic effects were assessed in streptozotocin (STZ)-nicotinamide (NA)-induced diabetic mice. Acute oral toxicity testing confirmed the HF344 extract's safety, with an LD50 exceeding 2000 mg/kg. Oral administration of HF344 extract (500 and 1000 mg/kg) in STZ-NA-induced diabetic mice significantly reduced the area under the fasting blood glucose (FBG)-time curve (AUC) in the oral glucose tolerance test (OGTT) model and treatment for 28-day reduced the FBG levels as compared with control (p < 0.05). This was accompanied by increased serum insulin levels and improved insulin resistance. HF344 extract also demonstrated a concentration-dependent inhibitory effect on malondialdehyde (MDA) production in vitro, with an IC50 of 7.24 μg/mL. Oral treatment with HF344 extract decreased MDA production in the homogenized muscle ex vivo collected from STZ-NA-induced mice. Furthermore, pretreatment with HF344 extract effectively restored the survival of RINm5F cells from STZ-induced damage. These findings suggest that HF344 is a promising polyherbal formula for managing blood glucose levels, enhancing insulin production, and providing antioxidant benefits in T2DM. Further research is required to evaluate the clinical efficacy and safety profiles of HF344.

Phytochemical Profile and Antioxidant and Protective Activities of Various Types of Extracts from Hyssopus officinalis L. and Grindelia robusta Nutt. Herb Grown in Poland.

The available literature indicates that Hyssopus officinalis and Grindelia robusta are raw materials with great potential for use in prevention and therapy. Therefore, the aims of this study were to assess the phytochemical profile and antioxidant and cytoprotective properties of extracts prepared using various solvents, additionally taking into account different methods of drying the plant material. Hydrodistilled oil was analysed by GC-MS. The chemical composition of the extracts was estimated by spectrophotometry and the HPLC-DAD method. Antioxidant activity was evaluated using DPPH and FRAP and measuring the intracellular level of ROS. Alamar Blue and Neutral Red tests were used to assess the cytotoxicity of the extracts on skin cells - keratinocytes and fibroblasts. The major components of hyssop essential oil were cis- (44.9%) and trans- (18.2%) pinocamphone, while borneol (16.1%), and α-pinene (12.0%) were predominant in grindelia essential oil. Flavonoids were dominant in the extracts (water:ethanol, water:methanol, and water: glycerol) from hot-air dried hyssop herb, while phenolic acids were the predominant compounds in the grindelia herb extracts. The water:ethanol hyssop extract had the highest total content of flavonoids (42.26 mg CE/mL), among which isoquercitrin and rutin were present in the highest quantities (32.61 mg/mL and 21.47 mg/mL, respectively). In the case of grindelia, the highest total phenolic acid content (26.24 mg CAE/mL) was recorded in the water:ethanol extract, and the dominant compounds among them were 1,5-dicaffeoylquinic and chlorogenic acid (10.85 and 6.39 mg/mL, respectively). The water:ethanol extract from both plants also exhibited the highest antioxidant activity in the DPPH and FRAP tests (79.19% and 1.39 mmol/L, respectively, for grindelia and 67.61% and 1.04 mmol/L for hyssop) and was most effective at reducing the level of ROS in cells. In addition, water:ethanol extracts may have a positive impact on the viability of skin cells in vitro. Water:ethanol extracts from H. officinalis and G. robusta herb are promising sources of active compounds and may find application as natural materials with valuable biological properties, which require further in vitro and in vivo testing.
