Experimental and real-life effectiveness of the herbal drug Sinupret® extract in the treatment of acute rhinosinusitis in the context of the strategy for the rational use of antibacterial drugs

Aim. To substantiate the clinical and experimental effectiveness of the herbal medicine Sinupret® extract for acute rhinosinusitis (ARS), with an emphasis on the strategy of rational use of antibiotics. Materials and methods. A meta-analysis of clinical studies ARhiSi-1 (EudraCT No. 2008-002794-13) and ARhiSi-2 (EudraCT No. 2009-016682-28), which included 676 patients, was performed. The main focus was on reducing Symptom Severity Scale (SSS) scores and improving Sinus Osteopathy Test (SNOT-20) scores with Sinupret® extract. In addition, a retrospective cohort study involving 203,382 patients was conducted to compare the real-world effectiveness of Sinupret® extract in reducing ARS-related side effects with antibiotics and other conventional treatments. Results. The use of the drug Sinupret® extract contributed to the improvement of symptoms of ARS, which was reflected in a decrease in the average score on the CVS by 1.9 points (p0.0001) and an improvement in the quality of life (QoL) of patients according to the SNOT-2 test, by 3.5 points (p=0.001) compared to placebo. In patients with moderate and severe symptoms, the effect of Sinupret® extract was even more significant (PVS -2.3 points; p0.0001; SNOT-20 -4.9 points; p=0.0158). Moreover, the use of the drug Sinupret® extract showed equal or greater effectiveness in reducing the risk of adverse outcomes associated with ARS, such as prescription of antibiotics, prolongation of illness by ≥7 days or the need to visit a doctor, especially compared with antibiotics. Conclusion. Sinupret® extract is a safe and effective treatment for ARS, which may help reduce the overuse of antibiotics.

Pain after Licorice or Sugar-Water Gargling in Patients Recovering from Oropharyngeal Surgery-A Randomized, Double-Blind Trial.

Glycyrrhiza glabrata (licorice) is used in traditional medicine and herbal remedies and reduces sore throats consequent to intubation, but whether it is protective for more intense pain after oropharyngeal surgery remains unclear. We thus tested the joint hypothesis that gargling with licorice, which has anti-inflammatory and antioxidant properties, reduces postoperative pain and morphine consumption. We enrolled patients having elective oropharyngeal surgery. Participants were randomly allocated to gargle with either 1 g licorice or a sugar placebo before and for up to three days after surgery. A numerical rating scale (NRS) for pain along with morphine consumption was evaluated every 30 min during the post-anesthesia care unit (PACU) stay and then three times daily for three days. We pre-specified that licorice gargling would be deemed better than sugar gargling only if found non-inferior on both morphine consumption and pain score and superior on at least one of the two. 65 patients were randomized to the licorice group and 61 to placebo. We found noninferiority (NI) in pain scores with an estimated mean difference of -0.09 (95.2% CI: -0.88, 0.70; p = 0.001; NI delta = 1) between licorice and placebo gargling. There were no adverse events reported in either group that required treatment discontinuation. Gargling with licorice did not significantly or meaningfully reduce postoperative pain or morphine consumption in patients recovering from oropharyngeal surgery. While higher doses might prove more effective, our results suggest that other topical analgesics should be considered.

The different acupoints are combined according to individuals, especially the application of Tinggong (SI 19) and Yamen (GV 15). The comprehensive treatment overlaps the dose effects, co-acts on activating blood circulation in meridians, calming-down the spirit and opening the orifices so that the therapeutic effect of acupuncture and moxibustion can be improved on this disease.

A Comprehensive Review of Self-Nanoemulsifying Systems in the Delivery of Herbal Drugs.

Self-nanoemulsifying drug delivery systems (SNEDDS) are an isotropic mixture of oils, co-surfactants, and surfactants and can form fine O/W Nanoemulsions in aqueous media. These components are advantageous in terms of improved solubility and bioavailability. Limited permeability, solubility, and bioavailability remain a significant challenge in developing herbal drugs. This review explores the potential of self-nanoemulsifying drug delivery systems (SNEDDS) as a promising strategy to overcome this problem. The SNEDDS is considered a novel technique for the delivery of low water-soluble drugs. It can bypass the first-pass metabolism, resulting in steady and sustained drug levels in the systemic circulation. The present article provides a comprehensive overview of the SNEDDS formulation of herbal drugs. It includes their composition, characterization, in vitro and in vivo studies conducted in various disease conditions, and pharmacokinetic studies.

Isolation, Development and Validation of Chromatographic Methods for the Estimation of Linoleic Acid from Different Parts of Euphorbia Neriifolia Linn.

Objectives: This is the first report on the development and validation of thin-layer chromatography (TLC) and high-performance thin-layer chromatography (HPTLC)-densitometric methods for the identification of linoleic acid (LA) in petroleum ether extract (PEE) of Euphorbia neriifolia (EN) stem (ST), latex (LX), and bark (BA). Methodology: Chromatographic analyses were performed on silica gel-G and silica gel 60 F254 plates and the antioxidant activities of isolated compounds were investigated by 2,2-diphenyl-1- picrylhydrazyl (DPPH) spectrophotometric assay. Results: The chromatographic analyses revealed better spots and well-separated peaks of LA with retention factor (Rf) values at 0.54 (ST), 0.40 (LX), and 0.64 (BA), respectively. The linearity of the calibration curve ranges from 10-50 ng/spot (ST), 10-100 ng/spot (LX), and 50-200 ng/spot (BA). The proposed method was characterized by better accuracy, better robustness, and good precision, ranging from 0.173 to 0.372% (intra-day) and 0.185 to 0.205% (inter-day). The value of the limit of detection and quantification equal to 1.04 and 3.16 ng/spot in ST, 0.87 and 2.64 ng/spot in LX, and 0.177 and 0.53 ng/spot in BA determined the sensitivity of the method. In the obtained chromatogram, no peak was observed other than the LA which determined the specificity of the method. The % RSD of < 2% after periods of 12, 24, 36, 48, and 72 h determined the stability of standard LA. Conclusion: Thus, the fingerprinting method is valuable in determining the adulterants and in routine quality control of formulations and herbal drugs.

Atractylodes Lancea and Its Constituent, Atractylodin, Ameliorates Metabolic Dysfunction-Associated Steatotic Liver Disease via AMPK Activation.

Metabolic dysfunction-associated steatotic liver disease (MASLD), which encompasses a spectrum of conditions ranging from simple steatosis to hepatocellular carcinoma, is a growing global health concern associated with insulin resistance. Since there are limited treatment options for MASLD, this study investigated the therapeutic potential of Atractylodes lancea, a traditional herbal remedy for digestive disorders in East Asia, and its principal component, atractylodin, in treating MASLD. Following 8 weeks of high-fat diet (HFD) feeding, mice received oral doses of 30, 60, or 120 mg/kg of Atractylodes lancea. In HFD-fed mice, Atractylodes lancea treatment reduced the body weight; serum triglyceride, total cholesterol, and alanine aminotransferase levels; and hepatic lipid content. Furthermore, Atractylodes lancea significantly ameliorated fasting serum glucose, fasting serum insulin, and homeostatic model assessment of insulin resistance levels in response to HFD. Additionally, a glucose tolerance test demonstrated improved glucose homeostasis. Treatment with 5 or 10 mg/kg atractylodin also resulted in anti-obesity, anti-steatosis, and glucose-lowering effects. Atractylodin treatment resulted in the downregulation of key lipogenic genes (Srebf1, Fasn, Scd2, and Dgat2) and the upregulation of genes regulated by peroxisome proliferator-activated receptor-α. Notably, the molecular docking model suggested a robust binding affinity between atractylodin and AMP-activated protein kinase (AMPK). Atractylodin activated AMPK, which contributed to SREBP1c regulation. In conclusion, our results revealed that Atractylodes lancea and atractylodin activated the AMPK signaling pathway, leading to improvements in HFD-induced obesity, fatty liver, and glucose intolerance. This study suggests that the phytochemical, atractylodin, can be a treatment option for MASLD.

Characterizing the Patterns of Cervical Cancer Symptom Recognition, Symptom Response, and Associated Factors Among Patients Treated in a Teaching Hospital in Ghana.

Cervical cancer is a major global health issue and ranks as the second leading cause of cancer-related deaths among women in Ghana. This study aimed to explore and characterize the patterns of symptom recognition associated with cervical cancer and the symptom responses among women in Ghana. A descriptive qualitative design utilizing 20 individual semistructured interview sessions was used. The study was conducted in one of Ghana's major cancer treatment centers. Data were collected using face-to-face interviews. The data were analyzed using NVivo 12 and presented as themes and subthemes. Data analysis revealed 2 main themes: barriers to symptom recognition and response and facilitators of early symptom recognition and symptom response. Barriers included deficient knowledge about cervical symptoms, spiritual attributions of symptoms, preference for herbal remedies for symptoms, misdiagnosis, and seeking help through multiple facility visits. Facilitating factors of symptom response include perceived severity/identification of additional symptoms, quick referrals with some navigation within the healthcare system, and advice from women's microcommunity. The study emphasizes the need for continuous educational efforts on cervical cancer and its symptoms. Healthcare providers, patients, and the public have a part to play in the awareness and early detection of cervical cancer. Initiatives that educate women about the early symptoms of cervical cancer and the importance of screening can help with early recognition. Educating communities about cervical cancer empowers individuals to take charge of their health and encourages supportive environments for women to seek care.

The goal of the current investigation was to evaluate its anti-cataract efficacy using both in vitro and in vivo tests in an experimental model of cataract caused by selenite.

Calendula Flowers (Calendulae officinalis flos): Methods to Obtain Fractions of Biologically Active Substances

INTRODUCTION. The pharmaceutical industry aims at developing sustainable resource-saving technologies for manufacturing medicines. Approaches to the effective use of herbal drugs include applying technologies yielding compounds with various pharmacological effects in one production cycle. To date, no standardised herbal drug processing technology has been designed to produce calendula flower-based medicinal products with various pharmacological effects. The Member States of the Eurasian Economic Union (EAEU) process calendula flowers by extraction methods yielding one fraction of biologically active substances per cycle (either only flavonoids or only carotenoids).AIM. This article aimed to investigate the possibility of stepwise processing of calendula flowers to obtain biologically active substances with different polarities (carotenoids, flavonoids, and polysaccharides) per cycle.MATERIALS AND METHODS. The authors extracted carotenoids using hexane. The study included additional thermal pretreatment of the herbal drug. Carotenoids and flavonoids were quantified by spectrophotometry, and polysaccharides were quantified by gravimetric analysis. After hexane removal, the dry oily residue was dissolved in oil with mechanical stirring to obtain the oil extract. The study included a three-step processing method that comprised hexane extraction (extraction of carotenoids with a low-polarity organic solvent), extraction with a water–organic solvent system (extraction of flavonoids), and aqueous extraction (precipitation of polysaccharides).RESULTS. The lipophilic extracts obtained by single hexane extraction or by single hexane extraction and heat treatment had the maximum carotenoid content (~4%), which was 10 times the carotenoid content in the extracts obtained using a water– organic solvent system. Oil extracts were prepared from the dry residue left after removing hexane by distillation at its boiling point. The content of biologically active substances in the oil extracts was comparable to that in the intact herbal drug. Water–organic solvent extraction yielded 68.5% more flavonoids from the herbal drug extracted with hexane than from the intact herbal drug. In contrast, aqueous extraction applied to the intact herbal drug yielded 1.7 times the amount of flavonoids obtained by aqueous extraction preceded by hexane extraction. The water-soluble polysaccharide fraction extracted from the intact herbal drug had 10 times the flavonoid content observed in the fraction extracted from the processed herbal drug. Each subsequent processing step decreased the total polysaccharide content and the content of individual polysaccharide fractions and increased their purity. The ratio of polysaccharide fractions remained unchanged across all processing methods tested.CONCLUSIONS. Stepwise processing of calendula flowers ensured that one processing cycle provided three fractions containing increased amounts of carotenoids, flavonoids, and polysaccharides. Relative to the intact herbal drug, there was a 3.3-fold increase in the yield of carotenoids, and the yields of flavonoids and polysaccharides increased by 44.8 and 41.3%, respectively. The resulting product had a higher degree of purity than the products obtained by pretreatment and double hexane extraction or by using the intact herbal drug. The stepwise processing method is advisable for the production of medicines that are enriched with a specific group of biologically active substances or contain smaller amounts of impurities.

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.

Wild-grown medicinal plants used by the Asháninka people from the Tambo River, Peruvian Amazonia

Ethnopharmacological relevanceThe Asháninka people are the largest Peruvian Amazonian group, yet the knowledge of their medicinal plants is scarce. This study on Asháninka herbal medicine offers an insight into the Asháninka aetiological system, resting within the wider ontological framework of animism, and cultural expressions of the biomedical understanding of illnesses. Aim of the studyTo document wild-grown (non-cultivated) plant species in current use by the Asháninka people and look closer at their herbal practices during the Covid-19 pandemic. The study examines whether the knowledge and use of medicinal plants is gendered in this society. It also compares the findings with available literature concerning the Arawakan groups from Peruvian Amazonia. Material and methodsThe fieldwork was conducted in 13 native communities of the Asháninka people along the Tambo River (Selva Central), Peru, between 2016 and 2018 and in 2022. The main field technique were guided walks in the forest with 27 female and 28 male participants, during which voucher specimens were collected and relevant information was recorded. Semi-structured interviews were performed with specialists in Asháninka traditional medicine and with lay Asháninka people to better understand Asháninka illness aetiologies. The analysis of medicinal plants included medicinal categories and uses, modes of preparations, the frequency of use and the knowledge about the plants between the genders. It also presents and discusses detailed testimonies of herbal remedies during the Covid-19 pandemic. The list of recorded plants was compared with ethnobotanical studies of other Arawakan groups from Peruvian Amazonia. ResultsAltogether, 169 wild-grown medicinal plant species were documented. Our findings highlight the importance of the Piperaceae and Acanthaceae botanical families in the Asháninka pharmacopoeia. The plants were used for 23 medicinal categories, of which dermatological disorders, digestive problems and venomous bites were the most prevalent. Over 70% of recorded plants were commonly and moderately known by the study participants. More exclusive species were found among the men than women; however, 64 % of all recorded plants were known to both genders. Sixty-one percent of recorded plants were not mentioned by any other study of medicinal plants among other Arawakan groups in Peruvian Amazonia. During the Covid-19 pandemic, nobody in the native communities at the Tambo River died directly due to the virus, which was attributed, amongst others, to effective and culturally-appropriate prophylaxis and treatments with medicinal plants. ConclusionTo this day, the Asháninka people at the Tambo River conserve the knowledge and practices related to medicinal plants which meet the daily needs of dwelling in subtropical forest; these are deeply rooted in animistic ontology, with the emphasis on spirit predation and retaliation. And yet, numerous applications of plants are compatible with the biomedical notion of illness and symptoms. Plant knowledge is shared between the genders, although specific plants exist for men and women, which are related to their gendered social and family roles. Some overlap and consensus exists with other studies regarding medicinal uses, which reflects the rich and diverse knowledge of medicinal plants among the Arawakan groups in Peruvian Amazonia, and this deserves further study.

Emerging Nanoparticle-Based Herbal Drug Delivery Systems for Colon Targeting Therapy

Abstract: Herbal medications hold a dominant position in the pharmaceutical sector due to their well-established therapeutic effects and extremely low negative effects. Besides, herbal remedies are easily available and highly economical. However, to circumvent the issue of poor bioavailability, the combinatorial strategy of incorporating herbal medicines and nano-technology is useful. The phytoconstituents molded in novel nanocarriers such as polymeric nanoparticles, polymeric micelles, liposomes, solid lipid nanoparticles, nanostructured lipid carriers, nanoemulsions, gold nanoparticles, etc., have been extensively investigated as they are the most promising approach for colon-targeting drug delivery systems. Although plant-based medicines have been developed for decades, there is enormous research interest in the development of an effective plant-derived delivery system for the incorporation of phytocon-stituents into various nanomaterials to overcome potential challenges related to solubility, bioavailability, and stability issues. The encapsulation of phytoconstituents in a novel nanocarrier is a promising approach to improving the bioavailability, stability, and therapeutic efficacy of herbal medicines. The herbal nanomedicines are used as a promising tool for tar-geted delivery to the colon, with potentially effective outcomes for the treatment of colonic diseases, viz., ulcerative colitis, diverticulitis, Crohn's disease, shigellosis, constipation, co-lonic polyps, colon cancer, etc. This article presents a comprehensive survey of recent find-ings and patents by innovators working exclusively on nanoparticles for the delivery of phy-tomedicines for colon targeting.

Challenges in diagnosis and treatment of cystinuria patients with Urolithiasis: multicenter patient centered study.

Cystinuria represents a rare cause of urolithiasis, accounting for 1% of all cases. However, it poses unique challenges in diagnosis and management. This study aimed to examine the challenges of managing cystine stones from the perspective of cystinuria patients. Following ethical approval, we reviewed the medical records of cystine stone patients treated at four tertiary centers from 2016 to 2021 and surveyed them on their perceptions of cystinuria. It included questions about demographic characteristics, herbal treatments, pain management, online engagement, disease outcomes, and cystinuria-related fears. The study included 28 adults with cystinuria nephrolithiasis, with a mean age of 30.5 years. Of these, 78.6% had consanguineous parents, and the first stone episode occurred at a mean of 14.82 years age. Family history of Cystinuria was encountered in 82.1%. Cystinuria was diagnosed after a mean of 6.43 years from the first stone episode, and stone analysis was performed in 22/28 after a mean of 3.86 years from the first stone episode. Only 17 patients (60.8%) underwent metabolic evaluation for kidney stones. Regarding non-surgical treatments, 13 (46.5%) patients received alkalinization medication, and only 10 (35.7%) were prescribed chelating agent therapy. Additionally, 50% of patients took herbal remedies. The diagnosis of cystinuria is often delayed, leading to a delay in receiving medical treatment (alkalinization and chelating agents) and poor health education and counseling. Thus, referring cystinuria patients to tertiary hospitals and providing a multidisciplinary approach might decrease the morbidity of the disease and enhance their well-being.

A Review on Nanotechnologically Derived Phytomedicines for the Treatment of Hepatocellular Carcinoma: Recent Advances in Molecular Mechanism and Drug Targeting.

The second largest cause of cancer-related death worldwide, Hepatocellular Carcinoma (HCC) is also the most common primary liver cancer. HCC typically arises in patients with liver cirrhosis. Existing synthetic medicines for treating chronic liver disease are ineffective and come with undesirable side effects. Although herbal remedies have widespread popularity, there is still a long road ahead before they are fully accepted by the scientific community. Secondary metabolites and phytochemicals found in plants are abundant in both the human diet and the non-human environment. Natural plant chemicals have been shown to be beneficial as therapeutic and chemopreventive treatments for a wide variety of chronic disorders. Many diseases, including HCC, can be effectively treated with the help of phytochemicals found in food. Resveratrol, curcumin, urolithin A, silibinin, quercetin, N-trans-feruloyl octopamine, emodin, lycopene, caffeine, and phloretin are all examples. Approximately, 60% of all anticancer medications are determined to be derived from natural substances, according to recent studies. Plant derivatives have played an important role in cancer due to their capacity to scavenge free radicals, limit cell proliferation, and set off apoptosis. The progression of HCC is linked to inflammatory signaling pathways, and this study sought to look at how novel approaches, such as phytomedicines, are being used to fight cancer. Recent advancements in molecular mechanisms and drug targeting for HCC have been discussed in this review.

Unlocking Toll-Like Receptors: Targeting Therapeutics for Respiratory Tract Infections and Inflammatory Disorders

Abstract: The Toll-like Receptors (TLRs) family has significantly enhanced the understanding of innate immune responses by identifying and responding to various microbes or host-derived organisms. TLRs contribute to these responses by increasing the levels of cytokines, interleukins, and other inflammatory mediators through multiple pathways. Located both intracellularly and on the surface of various cells and tissues, including vascular smooth muscles (VSMs) and myocardium cells, TLRs play distinct roles in innate immune activation, such as recognizing pathogen-associated molecular patterns (PAMPs) and activating downstream signaling pathways. In the context of COVID-19, TLRs are critically involved in the pathophysiology by mediating excessive inflammatory responses that exacerbate disease severity, influencing both the acute phase and long-term outcomes. It has been observed that inflammatory diseases such as atherosclerosis, viral myocarditis, and other comorbidities associated with the spread of COVID-19 have increased, although the exact mechanisms remain not fully understood. Nonetheless, there is evidence of TLR-mediated increased pro-inflammatory signaling by different mechanisms in these diseases. This review explains the role of TLRs in various inflammatory diseases related to COVID-19, including viral myocarditis, acute lung infections, and atherosclerosis. Furthermore, the review discusses various herbal drugs, such as Platycodon grandiflorum, Acanthopanax senticosus, Scutellaria baicalensis Georgi, and Engelhardia roxburghiana, and their mechanisms of action on TLRs, including NF-κB, MyD88-dependent, MyD88-independent pathways, and Plasmacytoid DCs. Enhanced clarity on TLRs' specific contributions to COVID-19 pathophysiology and stronger evidence supporting herbal interventions targeting TLRs could improve the impact and applicability of these findings in clinical settings.

<i>Oroxylum indicum</i> Kurz (L) leaf extract exerted antioxidant and anti-inflammatory effects on LPS-stimulated BV2 microglial cells

Purpose: To investigate the antioxidant and anti-inflammatory effects of Oroxylum indicum (L.) Kurz leaf extract on lipopolysaccharide (LPS)-activated BV2 microglia. Methods: BV2 cells were treated with LPS for 24 h in the presence or absence of Oroxylum indicum (O. indicum) leaf extract. The levels of reactive oxygen species (ROS), nitric oxide (NO), and interleukin 6 (IL-6) were quantified with CM-H2DCFDA, Griess reagent assay, and enzyme-linked immunosorbent assay (ELISA) test, respectively. The antioxidant activity of O. indicum leaf extract was assessed in vitro using DPPH, ABTS and FRAP assays. Results: Treatment with LPS resulted in significant increases in the levels of ROS, NO, and IL-6, when compared to untreated cells. However, co-treatment with O. indicum leaf extract significantly suppressed the production of these inflammatory markers (p < 0.05). In addition, the leaf extract of O. indicum exhibited antioxidant activity in the DPPH, ABTS, and FRAP assays. The contents of flavonoids and phenolics in O. indicum leaf extract were 13.25 ± 0.163 mg QE/g of dried extract and 82.58 ± 1.772 mg QE/g of dried extract, respectively (p < 0.05). Conclusion: The leaf extract of O. indicum exhibits anti-inflammatory and antioxidant properties in LPS-activated BV2 cells. This finding indicates that the leaf extract of O. indicum has promising potentials as a new source of herbal medication with anti- inflammatory properties. However, there is a need for more studies to unravel the fundamental mechanisms of their actions.

The emergence of antibiotic resistance and the evolution of new pathogenic strains have become significant global health challenges in the 21st century, necessitating the exploration of alternative therapeutic options. Herbal remedies, such as garlic, black cumin seed, and honey, have long been used in traditional medicine, but scientific validation of their antimicrobial potential remains crucial. This study aimed to explore the antimicrobial properties of garlic (Allium sativum), black cumin seed (Nigella sativa), and honey against bacteria and fungi. Various extraction methods, including cold pressing, Soxhlet extraction, hydrodistillation, and cold maceration, were used to obtain bioactive compounds from these natural ingredients. The antimicrobial activity of the extracts was evaluated in vitro using the disc diffusion method against Staphylococcus aureus (ATCC 25923), Bacillus cereus (ATCC 14579), Escherichia coli (ATCC 25922), Salmonella typhi (ATCC 19430), and Candida albicans (ATCC 10237). The results showed inhibition zones ranging from 0 to 35 mm, with black cumin oil demonstrating the highest antibacterial activity, particularly against E. coli and S. aureus. The minimum inhibitory concentrations (MIC) ranged from 6.25% to 50%. The study concluded that garlic, black cumin seed oil, and honey possess significant antimicrobial properties, either individually or in combination, suggesting their potential as natural alternatives to combat zoonotic bacterial infections and address the growing concern of drug-resistant pathogens. Further research is encouraged to explore their applications in real-world scenarios and develop new, natural antimicrobial therapies.

Phytotherapeutic BS012 and Its Active Component Ameliorate Allergic Asthma via Inhibition of Th2-Mediated Immune Response and Apoptosis.

Asthma is a chronic inflammatory disorder of the lungs that results in airway inflammation and narrowing. BS012 is an herbal remedy containing Asarum sieboldii, Platycodon grandiflorum, and Cinnamomum cassia extracts. To elucidate the anti-asthma effect of BS012, this study analyzed the immune response, respiratory protection, and changes in metabolic mechanisms in an ovalbumin-induced allergic asthma mouse model. Female BALB/c mice were exposed to ovalbumin to induce allergic asthma. Bronchoalveolar lavage fluid and plasma were analyzed for interleukin and immunoglobulin E levels. Histological analyses of the lungs were performed to measure morphological changes. Apoptosis-related mediators were assayed by western blotting. Plasma and lung tissue metabolomic analyses were performed to investigate the metabolic changes. A T-helper-2-like differentiated cell model was used to identify the active components of BS012. BS012 treatment improved inflammatory cell infiltration, mucus production, and goblet cell hyperplasia in lung tissues. BS012 also significantly downregulated ovalbumin-specific immunoglobulin E in plasma and T-helper-2-specific cytokines, interleukin-4 and -5, in bronchoalveolar lavage fluid. The lungs of ovalbumininhaled mice exhibited nerve growth factor-mediated apoptotic protein expression, which was significantly attenuated by BS012 treatment. Ovalbumin-induced abnormalities in amino acid and lipid metabolism were improved by BS012 in correlation with its anti-inflammatory properties and normalization of energy metabolism. Additionally, the differentiated cell model revealed that N-isobutyl-dodecatetraenamide is an active component that contributes to the anti-allergic properties of BS012. The current findings demonstrate the anti-allergic and respiratory protective functions of BS012 against allergic asthma, which can be considered a therapeutic candidate.

Bacterial diseases in Siniperca chuatsi: status and therapeutic strategies.

Mandarin fish (Siniperca chuatsi) is a prominent freshwater species with significant economic value in China, while disease poses a major hindrance to the advancement of mandarin fish aquaculture. To date, the understanding of the prevention and management of bacterial disease in mandarin fish remains incomplete. Therefore, there is a need for more comprehensive insights into the preventive and curative strategies to address these bacterial infections. In this review, we summarize the information pertaining to the predominant bacterial pathogens such as Aeromonas spp., Flavobacterium columnare, Edwardsiella tarda, Streptococcus uberis and Vibrio cholerae in the mandarin fish aquaculture, and point out the current strategies for diagnosis and combating these bacterial pathogens, as well as deliberate on the prospective alternative treatments such as vaccines, herbal remedies, and phage therapy for the prevention and control of these bacterial diseases. Furthermore, we also highlights the importance to implement an integrated bacterial disease management (IBDM) approach for the prevention and control of these pathogenic bacteria in aquaculture.

Role of Natural Products in Combatting Rheumatoid Arthritis: Phytochemical Strategies and Antioxidant Defences

Rheumatoid Arthritis (RA) is a persistent inflammatory autoimmune illness that damages bones by causing joint discomfort, edema, and stiffness. In RA, inflammatory cell infiltration and synovial hyperplasia lead to the generation of proinflammatory cytokines like TNF-α and IL-1. To find phytochemical substances utilised in RA treatment, SciELO, Virtual Health Library, and PubMed databases were searched for rheumatoid arthritis, herbal remedies, and medicinal plants. One of the predominant transcription factors is NF-κB, in regulating inflammatory response. Translocation of active NF-κB into the nucleus leads to gene transcription that produces proinflammatory cytokines. Oxidative stress changes transcription factors, which affects inflammatory gene expression. Phytochemicals have treated various diseases, blocking NF-κB translocation mitigates proinflammatory cascade activation (Withanolides, Gugglosterone, Epigallocatechin-3-gallate, O-glucosylcimifugin, Andrographolide, Curcuminoids, and Resveratrol), Flavonoids (Quercetin, Hesperidin, Kaempferol, Liquirin). Their therapeutic potential aids in creating safe and effective medicines for NF-κB-driven immune-inflammatory disorders like RA. This study emphasises the involvement of NF-κB in a series of events of inflammation, highlighting the role of phytochemicals in regulating its activity. It also discusses the effectiveness of polyphenols in relieving RA by blocking the signalling pathways and suggests a further study to support their usage.
