Objective In this study, zebrafish embryos are used to study the cytotoxic effects of a novel intracanal medication (ICM) based on zinc oxide nanoparticles (ZnO NPs) loaded with polyherbal extracts (Azadirachta indica and Solanum xanthocarpum). Material and methods In the present study, a green and sustainable method was employed for the synthesis of ZnO NPs mixed with bark and seed extracts of Azadirachta indica and Solanum xanthocarpum to be used as a polyherbal ICM. Formulation of ZnO NPs was confirmed with color change in mixture produced upon dissolving zinc acetate dihydrate in distilled water followed by slow addition of sodium hydroxide solution and herbal extracts. The effects of these green synthesized ZnO NPs were evaluated through a zebrafish embryo toxicity test. Embryos were exposed to different concentrations (25, 50, and 100 µg/mL) of synthesized experimental doses of ZnO NP and compared with the control embryos. Toxicological endpoints, such as the zebrafish embryo\'s survival rate, hatching rate, and heart rate, were noted and described. Results A concentration-dependent increase in mortality rate and hatching delay followed by declined heart rate was observed in green synthesized ZnO NP-treated embryos. The maximum toxicity was observed with an increase in the concentration of 100 µg/mL of the experimental dose, and at a low concentration of 25 µg/mL, it does not effectively show any developmental alteration in zebrafish embryos. Conclusion A novel polyherbal ICM loaded with ZnO NPs exhibited a dose-dependent effect on the heart rate, hatching, and mortality rate of the embryos. At optimal concentrations, the medication demonstrated minimal developmental malformations and cytotoxic effects, indicating its safety for use. However, increasing concentrations of the medication resulted in severe developmental malformations.

Teratogenicity and hyperuricaemia are the main side effects of favipiravir, an antiviral drug recently found its use to treat mild to moderate coronavirus (COVID-19) infections. This study investigated the beneficial effect of herbal extracts like Picrorrhiza kurroa (PK) and Scutellaria baicalensis (SB) and their active chemical constituents (baicalin and baicalein) on favipiravir-induced hepatotoxicity in rats. The formulation combinations included favipiravir, favipiravir + PK extract, favipiravir + pure baicalin, favipiravir + pure baicalein, and favipiravir + SB extract designated as F1, F2, F3, F4 and F5 respectively that were administered to rats orally for 21 days. Favipiravir caused increased levels of SGOT, SGPT, ALP, total bilirubin, and uric acid and decreased liver weight which was alleviated when alloherbal formulation of favipiravir and baicalein combination and favipiravir and SB extract was used. This paper highlights an attractive proposition to ameliorate favipiravir-induced hepatotoxicity using hepatoprotective agents.

UNASSIGNED: Wound healing is an intricate and continual process influenced by numerous factors that necessitate suitable environments to attain healing. The natural ability of wound healing often gets altered by several external and intrinsic factors, leading to chronic wound occurrence. Numerous wound dressings have been developed; however, the currently available alternatives fail to coalesce in all conditions obligatory for rapid skin regeneration.
UNASSIGNED: An extensive review of articles on herbal nano-composite wound dressings was conducted using PubMed, Scopus, and Google Scholar databases, from 2006 to 2024. This review entails the pathophysiology and factors leading to non-healing wounds, wound dressing types, the role of herbal bio-actives for wound healing, and the advantages of employing nanotechnology to deliver herbal actives. Numerous nano-composite wound dressings incorporated with phytoconstituents, herbal extracts, and essential oils are discussed.
UNASSIGNED: There is a strong substantiation that several herbal bio-actives possess anti-inflammatory, antimicrobial, antioxidant, analgesic, and angiogenesis promoter activities that accelerate the wound healing process. Nanotechnology is a promising strategy to deliver herbal bio-actives as it ascertains their controlled release, enhances bioavailability, improves permeability to underlying skin layers, and promotes wound healing. A combination of herbal actives and nano-based dressings offers a novel arena for wound management.

Toxocariasis is a zoonotic parasitic infection with worldwide distribution and high impact on human health. It has a limited clinical resolution with the available drugs, making it challenging to treat. Quercetin, which possesses biological and pharmacological qualities including antiparasitic, antioxidant, and anticancer activities, is a possible substitute for the current medications. Marine invertebrates can produce a vast array of different molecules, many of which are biologically active substances with distinct characteristics. In this study, we assessed the in vitro nematocidal effect of both quercetin and venom of Cassiopea andromeda (jellyfish) against third larvae of Toxocara canis. In microplates with Roswell Park Memorial Institute-1640 medium, larvae were incubated with ethanolic extract of quercetin (0.01, 0.02, 0.05, 0.08, 0.1, 0.25, and 0.5 mM/mL) and water extract of C. andromeda venom (15, 20, 25, 30, 35, 40, and 60 µg/mL) to evaluate their larvicidal effect. A scanning electron microscopy has investigated the possible effect of lethal concentration (LC90) of both extracts on the body wall of cultivated larvae, in comparison with those cultivated in albendazole. Our study revealed the effects of both quercetin and C. andromeda venom exposure on the mortality rate and the ultrastructure of T. canis third larva in comparison with control and albendazole-treated groups.

This study introduced an innovative magnetic effervescence-assisted microextraction method, streamlining the preparation of effervescent tablets through a one-pot method that blends a CO2 donor (Na2CO3) and an H+ donor (NaH2PO4) with bare magnetic particles (Fe3O4) and an adsorbent (hydroxylated multi-walled carbon nanotubes), followed by pressing. During the extraction process, the bare magnetic particles and adsorbent undergo in-situ self-assembly to create a magnetic adsorbent. The effervescence generates bubbles that enhance effective extraction and magnetism facilitates the easy separation of the magnetic adsorbent from the sample solution, completing the process within 4 min. Applied to organochlorine pesticide analysis in fruit juices and herbal extracts, the method exhibits excellent linearity (R2 > 0.993), sensitivity (detection limits: 0.010-0.125 ng/mL), accuracy (recoveries: 85.8-99.9%), and precision (RSDs < 9.7%) with GC-ECD. Overall, this approach stands out for its simplicity, cost-effectiveness, and suitability for on-site analysis, owing to its operational ease and independence from specialized equipment.

This study aims to investigate the use of pond apple (Annona glabra) compounds as a novel strategy to prevent and treat acute hepatopancreatic necrosis disease (AHPND) as well as to better understand the mechanism of health improvement in shrimp. The A. glabra leaf extracts were extracted using various solvents and examined for in vitro and in vivo activity against Vibrio parahaemolyticus strains. In comparison with ethanol and water extracts, methanol extract showed the strongest bactericidal effect (MBC/MIC ratio of 2.50 ± 1.00), with minimal inhibitory concentration (MIC) of 0.023 ± 0.012 mg ml-1 and minimum bactericidal concentration (MBC) of 0.065 ± 0.062 mg ml-1. White leg shrimp (P. vannamei, body weight 10.37 ± 0.27 g) fed A. glabra methanol extracts-containing diets (AMEDs) at 1 %, 1.5 %, and 2.0 % demonstrated no deleterious effects on survival and were significantly increased in length and weight after 30 days of feeding. The level of total haemocyte, hyaline haemocyte on day 15 and granulocyte on day 30 remarkably increased (p < 0.05) in shrimps fed AMEDs groups compared to those in the control group. The finding demonstrates that granulocyte was induced time dependently. In particular, the survival rate of V. parahaemolyticus challenged shrimps under medication with AMEDs at 1.5 % and 2.0 % was significantly higher (p < 0.05) than that of the control group. The decrease in bacterial load of Vibrio spp. and V. parahaemolyticus was obviously recorded in hepatopancreas shrimp given AMEDs 1.5 % and 2.0 % and may be linked to herb characteristics such as antibacterial activity, enhancing innate immunity, and its potential to maintain the integrity of hepatopancreatic tissue. Our findings suggest that A. glabra extract might be used as a health enhancer in commercial farmed shrimp.

UNASSIGNED: The majority of all kidney stone cases are oxalate urolithiasis with a high risk of recurrence. Beside its widespread occurrence, kidney stones are characterized by severe complications and high treatment costs. Probiotics and herbal medications could be forthcoming therapeutic interventions in the management of oxalate kidney stones.
UNASSIGNED: The PubMed/MEDLINE database was searched for keywords \"Oxalobacter formigenes\" AND \"Oxalate\" OR \"oxalate degradation\" AND \"Lactobacillus\" OR \"Bifidobacterium\" OR \"recombinant Lactobacillus\" OR \"Bacillus subtilis\", and \"urolithiasis\" AND \"herbal extract\". The search returned 253 results, 38 of which were included in the review.
UNASSIGNED: Most of the oxalate-degrading probiotics belong to the Oxalobacter formigenes, Lactobacillus, Bifidobacterium, and Bacillus genus with a minimum dosage of 107 CFU in the form of capsules, sachets, and lyophilized powder. Oxalate concentration in media was 5-50mM with an incubation time ranging from 24h to 14 days. The majority of the studies suggested that probiotic supplementation might be useful for reducing urinary excretion of oxalate and urea and alleviation of stone formation. Different herbal extracts were used on murine models of nephrolithiasis (induced by 0.5-3% ethylene glycol) with reduction of renal inflammation and urinary parameters, and calcium oxalate crystals.
UNASSIGNED: Several strains of probiotics and herbal extracts confer protective effects against kidney stone/nephrolithiasis, indicating their promising nature for being considered as elements of preventive / adjuvant therapeutic strategies.

UNASSIGNED: A double-blind, placebo-controlled, randomized, proof-of-concept trial aimed to evaluate the efficacy and safety of VerbasnolTM [Rehmannia glutinosa Libosch leaf-based extract (RGLE)] in females, with moderate to severe acne vulgaris.
UNASSIGNED: Twenty-two females aged 18 to 35 years having moderate to severe acne with Global Acne Grading System (GAGS) scores of 19 to 38 were included in the study and were randomized in a 1:1 ratio to receive either one capsule (100 mg/day) of RGLE or placebo orally after breakfast for 56 days. The primary outcome was a change in acne severity measured by the GAGS compared to the placebo on day 56. The secondary outcomes were changes in the number of inflammatory acne lesions, facial sebum secretion, quality of life, local pain and itching, skin wrinkle severity, and other skin characteristics, including radiance, luminosity, smoothness, texture, firmness, and hydration. Additionally, the percentage of responders and global tolerability and efficacy were evaluated.
UNASSIGNED: The mean GAGS score was reduced by 21.72% and 14.20% on day 28 in RGLE (n=10) and placebo groups (n=12), respectively, which further reduced in both groups on day 56. The RGLE group reported better improvement in other skin characteristics on day 56. No safety or tolerability concerns were reported for the extract. RGLE reduced acne and improved the skin quality in females compared to placebo as early as 28 days of supplementation.
UNASSIGNED: RGLE supplementation at a dose of 100 mg/day has provided a clinically relevant decrease in acne severity and improved the skin hydration and quality of life of the participants with acne after 56 days of dose administration.

BACKGROUND: As a representative local medicinal herb produced in China, Vladimiriae Radix (VR) has been proven to exert hepatoprotective and choleretic effects, with particular therapeutic efficacy in cholestatic liver injury (CLI), as demonstrated by the VR extract (VRE). However, the quality markers (Q-markers) of VRE for the treatment of CLI remain unclear.
OBJECTIVE: A new strategy based on the core element of \"efficacy\" was proposed, using a combination of spectrum-effect relationship, pharmacokinetics, and molecular docking methods to select and confirm Q-markers of VRE.
METHODS: First, the HPLC fingerprinting of 10 batches of VRE was studied, and the in vivo pharmacological index of anti-CLI in rats was determined. The spectrum-effect relationship was utilized as a screening method to identify the Q-markers of VRE. Secondly, Q-markers were used as VRE pharmacokinetic markers to measure their concentrations in normal and CLI rat plasma, and to analyze their disposition. Finally, molecular docking was utilized to predict the potential interaction between the identified Q-markers and crucial targets of CLI.
RESULTS: The fingerprints of 10 batches of VRE was established. The in vivo pharmacological evaluation of rats showed that VRE had a significant therapeutic effect on CLI. The spectrum-effect correlation analysis showed that costunolide (COS) and dehydrocostus lactone (DEH) were the Q-markers of VRE anti-CLI. The pharmacokinetic results showed that AUC(0-t), Cmax, CLZ/F, and VZ/F of COS and DEH in CLI rats had significant differences (P < 0.01). They were effectively absorbed into the blood plasma of CLI rats, ensuring ideal bioavailability, and confirming their role as Q-markers. Molecular docking results showed that COS, DEH had good affinity with key targets (FXR, CAR, PXR, MAPK, TGR5, NRF2) for CLI treatment (Binding energy < -4.52 kcal mol-1), further verifying the correctness of Q-marker selection.
CONCLUSIONS: In this study, through the combination of experimental and theoretical approaches from the aspects of pharmacodynamic expression, in vivo process rules, and interaction force prediction, the therapeutic effect of VRE and Q-markers (COS、DEH) were elucidated. Furthermore, a new idea based on the principle of \"efficacy\" was successfully proposed for screening and evaluating Q-markers.

Cimicifuga racemosa extracts (CREs) have gained well-established use for the treatment of menopausal symptoms such as hot flushes and excessive sweating, and weight gain. While the clinical effects of CREs have been well documented, the mechanisms underlying these effects are largely unknown. More recently, the metabolic effects of the CRE Ze 450 were demonstrated in cultured cells in vitro and in mouse models of obesity in vivo. At the molecular level, metabolic regulation, enhanced insulin sensitivity, and increased glucose uptake were linked to the activation of AMP-activated protein kinase (AMPK). Therefore, we tested the effects of Ze 450 on AMPK phosphorylation and thus activation in cells from different tissues, i.e., murine C2C12 myoblast cells, human HEPG2 liver cells, mouse HT22 neuronal cells, and in murine 3T3L1 adipocytes. Using a FRET-based HTRF-assay, we found that Ze 450 induced AMPK phosphorylation and the activation of this key enzyme of metabolic regulation in cells from various different tissues including C2C12 (muscle), HEPG2 (liver), HT22 (hippocampal), and 3T3-L1 (adipocyte) cells. In C2C12 muscle cells, enhanced AMPK activation was accompanied by reduced mitochondrial respiration and enhanced glucose uptake. Further, Ze 450 enhanced the resilience of the cells against oxidative death induced by ferroptosis inducers erastin or RSL3. Our findings suggest a general effect of Cimicifuga racemosa on AMPK activation in different tissues and across species. This may have a significant impact on expanded therapeutic applications of Ze 450, since AMPK activation and the related metabolic effects have been previously associated with anti-aging effects and the prevention of the metabolic syndrome.
