Lawsonia inermis-organically modified chitosan intercalated bentonite clay: A multifunctional nanotheranostic system for controlled drug delivery, sensing and cellular imaging.

This study presents the development of organo-bentonites (OBs); a cost-effective drug delivery system holding both sensing and imaging capabilities. The OBs were synthesized using quaternary ammonium cations derived from chitosan, Lawsonia inermis, and pyrene/anthracene carboxaldehyde combinations through a three-step process: Mannich reaction, quaternization, and intercalation. Physicochemical characterization confirms the organic modification of bentonite. The OBs: NQPB and NQAB hold substantial ciprofloxacin (Cipro) loading capacities (71.51 % and 78.04 %, respectively) and exhibit pH-dependent release profiles, suggesting their potential use as drug delivery platforms. Cell viability evaluation by MTT and live-dead assays indicates favourable results. Both OBs demonstrate fluorescence within the 450-500 nm range, and they display concentration-dependent fluorescence quenching and enhancement for NQPB and NQAB, respectively, in the presence of tryptophan (Trp), making them suitable for its detection. Confocal analysis further enunciates the live intracellular fluorescence upon OB uptake. In summary, the intrinsically fluorescent mesoporous OBs synthesized from Lawsonia inermis and chitosan exhibit multifunctionality, including Cipro delivery, Trp sensing, and live cell imaging. Among the OBs, NQAB could be considered as a promising theranostic platform owing to its superior cytocompatibility (>80 %), appreciable fluorescence, and controlled release profile.

Henna plant biomass enhanced azo dye removal: Operating performance, microbial community and machine learning modeling.

The bio-reduction of azo dyes is significantly dependent on the availability of electron donors and external redox mediators. In this study, the natural henna plant biomass was supplemented to promote the biological reduction of an azo dye of Acid Orange 7 (AO7). Besides, the machine learning (ML) approach was applied to decipher the intricate process of henna-assisted azo dye removal. The experimental results indicated that the hydrolysis and fermentation of henna plant biomass provided both electron donors such as volatile fatty acid (VFA) and redox mediator of lawsone to drive the bio-reduction of AO7 to sulfanilic acid (SA). The high henna dosage selectively enriched certain bacteria, such as Firmicutes phylum, Levilinea and Paludibacter genera, functioning in both the henna fermentation and AO7 reduction processes simultaneously. Among the three tested ML algorithms, eXtreme Gradient Boosting (XGBoost) presented exceptional accuracy and generalization ability in predicting the effluent AO7 concentrations with pH, oxidation-reduction potential (ORP), soluble chemical oxygen demand (SCOD), VFA, lawsone, henna dosage, and cumulative henna as input variables. The validating experiments with tailored optimal operating conditions and henna dosage (pH 7.5, henna dosage of 2 g/L, and cumulative henna of 14 g/L) confirmed that XGBoost was an effective ML model to predict the efficient AO7 removal (91.6%), with a negligible calculating error of 3.95%. Overall, henna plant biomass addition was a cost-effective and robust method to improve the bio-reduction of AO7, which had been demonstrated by long-term operation, ML modeling, and experimental validation.

Functionalization of bamboo fibers with lawsone dye (Lawsonia inermis) to produce bioinspired hybrid color composite with antibacterial activity.

There is great interest in using eco-friendly functional colorants with antibacterial activity to produce colorful textile and plastic products. In this study, we designed, produced, and analyzed a novel multifunctional hybrid color composite colorant with antimicrobial properties, prepared from plant-based products. The new functional color composite was prepared by stabilizing lawsone dye onto amino-silanized cellulose from bamboo fibers. X-ray photoelectron spectroscopy (XPS) and Fourier transform infrared (FTIR) spectroscopy were performed to examine the possible interactions between the lawsone dye and silanized bamboo fibers. The color performance, morphology, chemical stability, and thermal stability of the prepared color composite were evaluated using scanning electron microscopy (SEM), UV-Vis spectrophotometry, and thermogravimetric analysis (TGA). The results were compared to those for pure lawsone dye. Modification of amino-silanized bamboo fibers with lawsone dye led to the formation of a light brown colorant that is more resistant to organic solvents (e.g. acetone, ethanol) and elevated temperatures than raw natural dye. Importantly, the designed bamboo fiber/lawsone system (BF-APTES-L) benefits from the synergistic combination of lawsone and bamboo fibers, showing strong antibacterial activity compared to the control sample of bamboo-as evidenced by noticeably inhibited growth of E. coli, S. aureus, and B. subtilis.

Antibacterial Activity of Green Synthesized Silver Nanoparticles Using Lawsonia inermis Against Common Pathogens from Urinary Tract Infection.

New and creative methodologies for the fabrication of silver nanoparticles (Ag-NPs), which are exploited in a wide range of consumer items, are of significant interest. Hence, this research emphasizes the biological approach of Ag-NPs through Egyptian henna leaves (Lawsonia inermis Linn.) extracts and analysis of the prepared Ag-NPs. Plant extract components were identified by gas chromatography mass spectrometry (GC-mass). The analyses of prepared Ag-NPs were carried out through UV-visible (UV-Vis), X-ray diffraction (XRD), transmission electron microscope (TEM), scanning electron microscope (SEM), and Fourier transform infrared (FTIR) analysis. UV-Vis reveals that Ag-NPs have a maximum peak at 460 nm in visible light. Structural characterization recorded peaks that corresponded to Bragg's diffractions for silver nano-crystal, with average crystallite sizes varying from 28 to 60 nm. Antibacterial activities of Ag-NPs were examined, and it is observed that all microorganisms are very sensitive to biologically synthesized Ag-NPs.

Topical Henna Application Causing Acute Kidney Injury and Acute Hemolytic Anemia.

Body art by henna staining is a practice that is widely prevalent in the Middle East and Africa, and has been known to be in vogue for hundreds of years. The practice is also significant as a ceremonial custom for weddings and social gatherings. However, due to its natural components (Lawsone) and additives, including para-phenylene-diamine (PPD), henna has also been associated with a number of health hazards, including acute hemolysis and acute kidney injury (AKI). We report in this case, a female patient who presented with AKI and acute hemolytic anemia following excessive pre-wedding henna staining of her arms and legs.

Among different concentrations of the MHE, 100mg/ml and above concentrations showed inhibitory effect against afore said bacteria. The MIC for Staphylococcus aureus and Klebsiella pneumoniae were 100mg/ml in MHE. The MIC of Ciprofloxacin was 1µg/ml against Staphylococcus aureus and 1.5µg/ml for Klebsiella pneumoniae. The MIC of Ciprofloxacin was the lowest in comparison to MICs of MHE for the test organisms. This study showed that Methanol Henna extracts demonstrated antibacterial effects against pathogens. From this study, it is clearly observed that there is definite antibacterial effect of the methanolic extract of Henna leaves (Lawsonia inermis) against Staphylococcus aureus and Klebsiella pneumoniae.

In Vivo Wound-Healing Effect of Chemical and Green Synthesized Chitosan Nanoparticles Using Lawsonia inermis Ethanolic Extract.

Wounds can be a result of surgery, an accident, or other factors. There is still a challenge to find effective topical wound-healing agents. This study aims to investigate the wound-healing activity of chemical and green synthesized chitosan nanoparticles (Ch-NPs) using Lawsonia inermis leaves extract. The nanoparticles were morphologically and chemically characterized using X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), and high-resolution transmission electron microscopy (HRTEM). Forty-five adult female albino rats were randomly divided into three groups. The cutaneous surgical wounds were topically treated with 0.9% normal saline (control group), green Ch-NPs (second group), and chemical Ch-NPs gels (third group), respectively. The clinical picture of wounds and histopathological changes were assessed on the 3rd, 7th, 14th, and 21st days post-treatment. X-ray diffraction analysis revealed great crystallinity and purity of nanoparticles. The studied nanoparticles increased the wound contraction percent (WC%), reduced healing time and wound surface area (WSA), and these results were backed up by histological findings that indicated improved epithelialization, dermal differentiation, collagen deposition, and angiogenesis in treated rats compared with control rats (p < 0.05). We concluded that the wound-healing effects of the studied nanoparticles are encouraging, and further studies for complete assessment are still needed.

The potentiality of biostimulant (Lawsonia inermis L.) on some morpho-physiological, biochemical traits, productivity and grain quality of Triticum aestivum L.

BACKGROUND: In conformity with the international trend to substitute the artificial agro-chemicals by natural products to improve growth and productivity of crops, there is a necessity to focus on the environment sustainable and eco-friendly resources to increase crops productivity per unit area. One of these resources is the use of biostimulants. The aim of this study is to allow the vertical expansion of wheat crop by improving its growth and productivity per unit area as well as enhancing its grain quality using henna leaf extract as a biostimulant. RESULTS: Field study was conducted to evaluate the potentiality of different doses of henna leaf extract (HLE) for improving the performance of wheat plants (Triticum aestivum L.) at three development stages. Results revealed that the response was dose dependent hence both 0.5 and 1.0 g/L doses significantly enhanced the growth of shoot and root systems, biochemical traits, yield and yield related components with being 1.0 g/L the most effective one. Furthermore, 1.0 g/L HLE markedly enhanced the quality of the yielded grains as revealed by increasing the content of soluble sugars (23%), starch (19%), gluten (50%), soluble proteins (37%), amylase activity (27%), total phenolics, flavonoids and tannins (67, 87 and 23%, respectively) as well as some elements including Ca (184%), Na and Fe (10%). Also, HPLC analysis of grains revealed that 1.0 g/L dose significantly increased the level of different phytohormones, soluble sugars and flavonoids (quercetin, resveratrol and catechin). CONCLUSION: Application of Henna (Lawsonia inermis) leaf extract at 1.0 g/L dose as a combination of seed priming and foliar spray can be recommended as a nonpolluting, inexpensive promising biostimulant, it can effectively enhance wheat growth, biochemical traits and productivity as well as improving the quality of the yielded grains.

The MIC for Staphylococcus aureus and Escherichia coli were 100 and 350mg/ml in CHE respectively. The MIC of Ciprofloxacin was 1µg/ml against both Staphylococcus aureus and Escherichia coli. The MIC of Ciprofloxacin was the lowest in comparison to MICs of CHE for the test organisms. The present study showed that Chloroform Henna extracts demonstrated antibacterial effects against food borne pathogens. From this study, it is clearly observed that there is definite antibacterial effect of the chloroform extract of Henna leaves against Staphylococcus aureus and Escherichia coli.

Lawsonia inermis-loaded poly (L-lactide-co-D, L-lactide) nanofibers for healing acceleration of burn wounds.

This study aimed to develop a new bioactive wound dressing based on electrospun poly (L-lactide-co-D, L-lactide) (PLDLLA) nanofibers containing Lawsonia inermis (LI) for burn wounds. The SEM results showed that loading LI increased the average diameter of PLDLLA nanofibers to 528 nm with smooth and beadless morphology. The analysis of LI release from PLDLLA nanofibers and film samples was measured by UV-vis spectrophotometry, and the obtained results revealed that LI molecules could diffuse from the nanofibrous sample with higher rate than film during 48 h. In this regard, the PLDLLA nanofibrous sample as a drug carrier has advantages compared to the film. Moreover, the antibacterial results confirmed the positive influence of LI related to the bacteria which in turn the growth inhibition zones were increased from 6 to 22 mm for P. aeruginosa, and from 3 to 16 mm for S. aureus while the LI concentration was set at 1.4% (w/v). Finally, animal model studies demonstrated that PLDLLA-LI nanofibers accelerated burn wound closure remarkably; thereby decreasing the wound area approximately 90% during the treatment period of 19 days. The histological observations dedicated that the appearance of the epithelial layer was increased dramatically alongside the thickness of around 40% for the wound treated with PLDLLA-LI nanofibrous sample rather than that without LI. Besides the epithelialization, it has been found that the wound covered by PLDLLA-LI wound dressing has condensed collagen fibers with no necrosis.

Structural determination and anticholinesterase assay of C-glycosidic ellagitannins from Lawsonia inermis leaves: A study supported by DFT calculations and molecular docking.

An ellagitannin monomer, lythracin M (1), and a dimer, lythracin D (2), along with eight known monomers (3-10) were isolated from Lawsonia inermis (Lythraceae) leaves. Lythracin M (1) is a C-glycosidic ellagitannin with a flavogallonyl dilactone moiety that participates in the creation of a γ-lactone ring with the anomeric carbon of the glucose core. Lythracin D (2) was determined as an atropisomer of the reported lythcarin D. These newly discovered structures (1 and 2) were determined by intensive spectroscopic experiments and by comparing DFT-calculated 1H1H coupling, 1H NMR chemical shifts, and ECD data with experimental values. The anti-acetylcholinesterase assay of the compounds 1-10 revealed that the C-1 ellagitannin epimers [casuarinin (7; IC50 = 34 ± 2 nM) and stachyurin (8; IC50 = 56 ± 3 nM)], and the new dimer (2; IC50 = 61 ± 4 nM) possess enzyme inhibitory effects comparable to the reference drug (donepezil, IC50 = 44 ± 3 nM). Molecular docking of compounds 1-10 with AChE identified the free galloyl moiety as an important pharmacophore in the anticholinesterase activity of tannins.

Comparing Dermolina-Henna Cream with Mometasone Cream in Improving Radiodermatitis Among Patients with Breast Cancer: A Randomized Active-Control Double-Blind Clinical Trial.

Objectives: Radiotherapy is one of the treatments used for different types of cancer. Acute radiodermatitis is one of its most common complications. Despite the high prevalence of radiodermatitis, few studies investigated how to prevent or treat this complication. Hence, a standard treatment has not been introduced so far. We sought to evaluate the efficacy of Dermolina-Henna cream, a new polyherbal formulation, compared to Mometasone cream for alleviating acute radiodermatitis among breast cancer patients. Design: Randomized active-control double-blind clinical trial. Setting/Location: The oncology clinic of Shohaday-e Tajrish Hospital (Tehran, Iran). Subjects: Women older than 18 years with breast cancer undergoing radiotherapy. Interventions: Patients were instructed to apply a thin layer of Dermolina-Henna or Mometasone cream once daily on their lesions at least 3 h after radiotherapy for 4 weeks, and if grade I or II radiodermatitis developed, also afterward. Patients were visited weekly until end of study at after 4 weeks. Radiation Therapy Oncology Group standard questionnaires were evaluated and recorded every week as the primary outcome. Outcome measures: Primary outcome was defined as evaluating the efficacy of Dermolina-Henna cream to change the radiodermatitis grade, while the level of patients' satisfaction and the rate of adverse events recorded by patients were secondary outcomes. Results: The trends on decrease in number of lesions, erythema, radiodermatitis grade, burning sensation, pain, and itchiness were statistically significant for each treatment, separately (p < 0.001), except for radiodermatitis grade in Mometasone group (p = 0.4). Dermolina-Henna was significantly better than Mometasone in alleviating burning sensation (p < 0.001) and itchiness (p = 0.041). Approximately 3.7% of patients showed adverse events and 3.7% declared dissatisfaction in both groups. Conclusions: In summary, we showed that Dermolina-Henna cream and Mometasone cream were significantly effective in decreasing severity of radiodermatitis symptoms among patients with breast cancer. Dermolina-Henna cream was significantly superior to Mometasone cream in alleviating burning and itchiness. Clinical Trial Registration Number: IRCT20200115046144N1.

Biosynthesis of silver nanoparticles using Lawsonia inermis and their biomedical application.

Developing biosynthesis of silver nanoparticles (Ag-NPs) using plant extract is an environmentally friendly method to reduce the use of harmful chemical substances. The green synthesis of Ag-NPs by Lawsonia inermis extract and its cellular toxicity and the antimicrobial effect was studied. The physical and chemical properties of synthesised Ag-NPs were investigated using UV-visible spectroscopy, infrared spectroscopy, X-ray diffraction (XRD), scanning, and transmission electron microscopy. The average size of Ag-NPs was 40 nm. The XRD result shows peaks at 2θ = 38.07°, 44.26°, 64.43°, and 77.35° are related to the FCC structure of Ag-NPs. Cytotoxicity of synthesised nanoparticles was evaluated by MTT toxicity test on breast cancer MCF7 cell line. Observations showed that the effect of cytotoxicity of nanoparticles on the studied cell line depended on concentration and time. The obtained IC50 was considered for cells at a dose of 250 µg/ml. Growth and survival rates decreased exponentially with the dose. Antimicrobial properties of Ag-NPs synthesised with extract were investigated against Escherichia coli, Salmonella typhimurium, Bacillus cereus, and Staphylococcus aureus to calculate the minimum inhibitory concentration and the minimum bactericidal concentration of (MBC). The results showed that the synthesised Ag-NPs and the plant extract have antimicrobial properties. The lowest concentration of Ag-NPs that can inhibit the growth of bacterial strains was 25 µg/ml.

Antibacterial and anti-trichomunas characteristics of local landraces of Lawsonia inermis L.

BACKGROUND: Henna (Lawsonia inermis) with anti-bacterial properties has been widely used in traditional medicine especially Persian medicine. Henna oil is suggested for diseases of infectious origin, such as cervical ulcers. Group B Streptococcus agalactiae, Pseudomonas aeruginosa and, Trichomonas vaginalis are involved in the infection of women especially cervicitis. Henna grows in dry and tropical regions. The main important landraces of henna landraces are cultivated in Kerman, Sistan and Baluchestan, Hormozgan, and Bushehr provinces in Iran. Proper use of antimicrobial agents, use of new antimicrobial strategies, and alternative methods, such as herbal methods may help reduce drug resistance in the future. This study's objective was to investigate the anti-Trichomonas vaginalis activity of three different henna landraces and antimicrobial effects against group B Streptococcus agalactiae and, Pseudomonas aeruginosa. METHODS: Total phenol content was measured by Folin ciocaltu method. Antibacterial effect of landraces of Henna against P. aeruginosa and S. agalactiae were assayed by well diffusion method and minimal inhibitory concentration assessments were done using the broth micro-dilution technique. Anti-Trichomonas effect of Henna landraces were assayed by Hemocytometery method. RESULTS: Total phenol content of Shahdad, Rudbar-e-Jonub, and Qaleh Ganj was 206.51, 201.96, and 254.85 µg/ml, respectively. Shahdad, Rudbar-e-Jonub, and Qaleh Ganj had MIC against GBS at 15, 15 and, 4 µg/ml. The growth inhibition diameter of the most effective henna (Shahdad landrace) at a concentration of 20 µg/ml on P. aeruginosa was 2.46 ± 0.15 cm and in the MIC method at a concentration of 5 µg/ml of Shahdad landrace, P. aeruginosa did not grow. IC50 of shahdad Henna after 24 h, 48 h, and 72 h was 7.54, 4.83 and 20.54 µg/ml, respectively. IC50 of Rudbar-e-Jonub extract was 5.76, 3.79 and 5.77 µg/ml in different days. IC50 of Qaleh Ganj extract was 6.09, 4.08 and 5.74 µg/ml in different days. CONCLUSIONS: The amount of total phenol in Qaleh Ganj was higher than the other varieties. In the well diffusion method, Qaleh Ganj was more effective against group B Streptococcus (Gram-positive bacterium) than the other two landraces, and Shahdad landrace was more effective against P. aeruginosa (Gram-negative bacterium) than other. In the MIC method, the same result was obtained as in the well diffusion method, but at a lower concentration.

Evaluation Of Anti-inflammatory Mediated Anti-hemorrhoidal Activity of Lawsonia inermis on Croton Oil Induced Hemorrhoidal Rats.

BACKGROUND: Hemorrhoids are a common recto-anal disorder commonly known as piles or tissue clumps in the rectum. In normal individuals, they were known as anal cushions. In the anus, they are composed of rectal blood vessels, muscles, and elastic fibres. When bulged, it can cause bleeding, constipation, itching, severe pain, and bleeding in the anus. Inflammation of the anal cushion remains major pathogenesis for the development of hemorrhoids. Inflammatory mediators like neutrophils, TNF-α, and IL-6 seem to play a major role in the development of disease. OBJECTIVE: This study aims to carry out the ethanolic leaf extract of Lawsonia inermis (L. inermis) and evaluate its anti-hemorrhoidal activity both in vitro and in vivo. Furthermore, Molecular Docking was performed on the crystal structure of COX-2 with the selective compound 23d-(R) (PDB ID: 3NTG) protein. METHODS: The current study is to estimate an anti-inflammatory mediated anti-hemorrhoidal activity of ethanolic leaf extract of L. inermis at different doses of 200 mg/kg/ir and 400 mg/kg/ir in croton oil-induced hemorrhoidal rats. Pilex ointment is taken as a reference standard in the present study. Evan's blue extravasation technique were applied in the study to quantify the proinflammatory protein. RESULTS: From the study results, a dose-dependent effect was found for ethanolic leaf extract of Lawsonia inermis at 200 mg/kg and 400 mg/kg causing a significant reduction of serum Proinflammatory mediators TNF-α, IL-6, and plasma neutrophils in croton oil-induced hemorrhoidal rats. CONCLUSION: Studies represented that the plant extract can significantly inhibit protein denaturation of egg albumin in in vitro and found to reduce croton oil induced inflammatory mediators in hemorhhoidal rats.

PURPOSE: In this clinical trial, we evaluated Alpha® ointment efficacy in prevention of capecitabine induced hand-foot syndrome (HFS) in patients with gastrointestinal or breast cancers, for the first time. METHODS: During this pilot, randomized, triple-blinded, placebo-controlled clinical trial, the effect of Alpha® ointment (Lawsonia inermis 3 g and Curcuma longa 0.15 g/ 30 g) was assessed. It was applied on the palms and the soles, two times daily starting at the first day of chemotherapy for 4 consecutive courses. The severity of HFS was assessed at the end of the chemotherapy courses based on World Health Organization (WHO) scale and scored between 0-4. RESULTS: Ninety eligible patients were included randomly in the treatment or placebo group. Median WHO HFS grade was not significantly different between the two groups, during the follow-up period (P > 0.05). In the weekly assessment, the scores increased meaningfully in both the placebo and treatment groups, but there was a delay in HFS occurrence and deterioration in Alpha ointment group based on post hoc analysis. CONCLUSION: Administration of Alpha® ointment containing henna and curcumin could not significantly prevent capecitabine induced HFS during 4 courses of treatment, but can somewhat delay its occurrence in patients with gastrointestinal or breast cancer.
