RESUMO
Background: Consumption of herbal medicines among people living with HIV is a common practice in Sub-Saharan Africa. The utilization of herbal medicines was at 17.5% and 67.9% in Malawi and Nigeria, respectively. There is inadequate data on use and adverse reactions (ADRs) reporting of herbal medicines among people living with HIV (PLWHIV). This study was designed to investigate use and ADRs reporting of herbal medicines among PLWHIV at the University Teaching Hospitals in Blantyre, Malawi and Ibadan, Nigeria. Methodology: A cross-sectional study was conducted among PLWHIV attending Antiretroviral Therapy (ART) clinic at Queen Elizabeth Central Hospital, Blantyre, Malawi and University College Hospital, Ibadan, Nigeria. A structured questionnaire was administered to 360 and 370 participants in Blantyre and Ibadan respectively, through face-to-face interviews after obtaining their informed consent. Results: The prevalence of herbal medicines use among PLWHIV in Malawi and Nigeria was at 80.6% and 55.7% (p<0.001), respectively. The most frequently used herbal medicines in Malawi were Aloe vera (14.0%), Moringa oleifera (14.0%), Zingiber officinale (13.0%) and Allium sativum (7.0%). Likewise, in Nigeria, the most commonly used herbal medicines were Zingiber officinale (15.0%), Vernonia amygdalina (14.0%), Moringa oleifera (9.0%), and Allium sativum (11.0%). The major reason for herbal medicines' use in Malawi was ready availability (42.1%) and perception that it boosts immunity (44.6%) in Nigeria. The PLWHIV reported experiencing suspected herbal medicine ADRs in Malawi (3.9%) and in Nigeria (8.0%). Conclusion: A higher percentage of people living with HIV are using herbal medicines in Malawi as well as in Nigeria. In both countries, a few participants reported experiencing suspected ADRs related to herbal medicines.

Non-small cell lung cancer (NSCLC) poses a global health threat, and epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) such as gefitinib, afatinib, and osimertinib have achieved significant success in clinical treatment. However, the emergence of resistance limits the long-term efficacy of these treatments, necessitating urgent exploration of novel EGFR-TKIs. This review provides an in-depth summary and exploration of the resistance mechanisms associated with EGFR-TKIs, with a specific focus on representative drugs like gefitinib, afatinib, and osimertinib. Additionally, the review introduces a therapeutic strategy involving the combination of Chinese herbal medicines (CHMs) and chemotherapy drugs, highlighting the potential role of CHMs in overcoming NSCLC resistance. Through systematic analysis, we elucidate the primary resistance mechanisms of EGFR-TKIs in NSCLC treatment, emphasizing CHMs as potential treatment medicines and providing a fresh perspective for the development of next-generation EGFR-TKIs. This comprehensive review aims to guide the application of CHMs in combination therapy for NSCLC management, fostering the development of more effective and comprehensive treatment modalities to ultimately enhance patient outcomes.
RESUMO
CONTEXT: Derris reticulata Craib. and Glycyrrhiza glabra L., of the Fabaceae, have been used as active components in Thai herbal formulas for the treatment of fever and skin diseases. OBJECTIVE: To evaluate the physicochemical and pharmacological properties of the developed herbal gel formulation containing the combined extract from D. reticulata stem wood and G. glabra root (RGF). MATERIALS AND METHODS: The potential of the herbal gel formulation containing RGF (8% w/w) as the active ingredient was studied by evaluating the anti-inflammatory, antioxidant, and anti-Staphylococcus aureus activities using quantitative reverse transcription-polymerase chain reaction assay, spectrophotometric method, and broth microdilution technique, respectively. The reference standards for the biological testing included Nω-nitro-L-arginine (L-NA), ascorbic acid, catechin, and penicillin G. The stability study of the RGF herbal gel was performed by a heating-cooling test (at 45 °C for 24 h and at 4 °C for 24 h/1 cycle; for 6 cycles), and the bioactive marker compounds in the herbal gel were investigated by the HPLC technique. RESULTS: RGF showed promising pharmacological effects, particularly on its anti-inflammatory property (IC50 73.86 µg/mL), compared to L-NA (IC50 47.10 µg/mL). The RGF-containing gel demonstrated anti-inflammatory (IC50 3.59 mg/mL) and free radical scavenging effects (IC50 0.05-4.39 mg/mL), whereas it had no anti-S. aureus activity (MIC > 10 mg/mL). The active ingredient in the developed herbal gel significantly inhibited lipopolysaccharide-induced nitric oxide production by downregulating iNOS mRNA levels. The contents of the bioactive markers in the RGF gel (lupinifolin and glabridin) did not change significantly after stability testing. DISCUSSION AND CONCLUSIONS: The RGF-containing gel has potential to be further developed as an herbal product for the treatment of skin inflammation.

Many herbs have been shown to safely and successfully treat hyperlipidemia. However, the molecular mechanisms underlying their treatment remain unclear. In this study, 103 prescriptions for the treatment of hyperlipidemia containing 146 herbs were screened. Cluster analyses identified a core prescription comprising five herbs, namely, Crataegus pinnatifida (Shan Zha), Cassiae semen (Jue Ming Zi), Alisma orientale (Sam.) Juz. (Ze Xie), Salvia miltiorrhiza (Dan Shen), and Radix Polygoni Multiflori (He Shou Wu), in combination for the treatment of hyperlipidemia. Next, 9, 62, 5, 132, and 34 potential targets for each of the core herbs and a total of 512 hyperlipidemia-related protein targets were detected. Finally, 40 targets shared by core herbs and hyperlipidemia were identified. IL6, AKT1, IL1B, PTGS2, VEGFA, PPARG, and NOS3 were the seven proteins that were found to be most important in the treatment of hyperlipidemia. Interestingly, the Kyoto Encyclopedia of Genes and Genomes pathway indicated that these targets were mainly enriched in the lipid and atherosclerosis pathway and the cancer pathway. In addition, core target proteins such as AKT1, PTGS2, and PPARG have been demonstrated to play critical roles in hyperlipidemia and pancreatic cancer. Significant affinity between bioactive chemicals and proteins involved in cancer pathways was found by molecular docking. Molecular docking results showed that AKT1, PTGS2, and PPARG exhibited good binding ability with three bioactive chemicals, including 3-beta-hydroxymethyllenetanshiquinone, danshexinkum d, and physciondiglucoside. The treatment of hyperlipidemia by herbs may be mediated through the modulation of proteins associated with the cancer pathway. This study helps to provide a theoretical basis for future combined therapy for hyperlipidemia and cancer. [Figure: see text].
RESUMO
Background: Non-alcoholic fatty liver disease (NAFLD) is a common liver disorder characterized by hepatic steatosis, inflammation and fibrosis. Ganfule (GFL), a traditional Chinese medicine, has demonstrated therapeutic potential in the treatment of NAFLD but the mechanisms involved are not fully understood.To evaluate the biochemical mechanisms of GFL in treating NAFLD by examining its effects on biological networks, key therapeutic targets, histopathological changes and clinical implications. Methods: Chemical component screening, key target prediction, biological functional enrichment analysis, lipid profile localization analysis and complex network analysis were performed on GFL using multi-database mining, network analysis and molecular docking. An NAFLD rat model was then established and treated with different doses of GFL. Histopathological evaluation and western blotting were used to verify the expression levels of key target proteins in GFL-treated NAFLD rats. Results: Network analysis analysis identified 12 core targets, 12 core active ingredients and 7 core Chinese medicinal herbs in GFL potentially involved in the treatment of NAFLD. Biological functional enrichment analysis revealed the involvement of lipid metabolism, apoptosis and intracellular signaling pathways. Molecular docking confirmed a strong affinity between GFL's core compounds and certain target proteins. Histopathological examination of an NAFLD rat model showed reduced hepatocellular steatosis after GFL treatment. Western blotting revealed significant downregulation of PPARA and PPARD protein expression and upregulation of PIK3CG and PRKACA protein expression in NAFLD rats treated with lower doses of GFL. Conclusions: Our results suggest that GFL modulates key proteins involved in lipid metabolism and apoptosis pathways. GFL improved the histopathological features of NAFLD rats by regulating lipid metabolism as well as reducing hepatocyte apoptosis and hepatocellular steatosis. These findings offer insights into the biochemical mechanism of action of GFL and support its use in the treatment for NAFLD.
RESUMO
Objectives: Nitric oxide is the most important mediator of penile erection after the onset of sexual excitement. It activates cyclic guanosine monophosphate (cGMP), increasing penile blood flow. Most pharmaceutical medications prevent enzyme phosphodiesterase type 5 (PDE-5) from breaking down cGMP, thus keeping its level high. However, due to the adverse effects of pharmacological therapies, herbal drugs that improve sexual function have gained attention recently. This study aimed to investigate the combined effects of ginseng, Tribulus terrestris, and L-arginine amino acid on the sexual performance of individuals with erectile dysfunction (ED) using the 5-item version of the International Index of Erectile Function (IIEF-5) questionnaire. Methods: Over three months, 98 men with erectile dysfunction were randomly assigned to receive either 500 mg of herbal supplements or placebo pills. Each herbal tablet contained 100 mg of protodioscin, 35 mg of ginsenosides, and 250 mg of L-arginine. Results: The results showed that the changes in the average scores of ILEF-5 within each group before and after the intervention indicated that all parameters related to the improvement of sexual function in patients with erectile dysfunction improved in the herbal treatment group (p < 0.001). The herbal group significantly improved IIEF-5 scores in non-diabetics (p < 0.05). However, there was no significant difference in the changes of IIEF-5 scores between the two intervention and control groups in diabetic patients. Conclusion: In conclusion, ginseng, Tribulus terrestris, and L-arginine have properties that increase energy and strengthen sexual function, making them suitable for patients with sexual disorders.
RESUMO
The regulation and use of herbal medicines is a topic of debate due to concerns about their quality, safety, and efficacy. EU Directive 2004/24/EC on Herbal Medicinal Products was a significant step towards establishing a regulatory framework for herbal medicinal products in the EU, and bridging the gap between conventional and herbal medicines. This Directive allows herbal medicinal products to be marketed in the EU through full marketing authorisation, well-established use, and traditional use of herbal medicinal products. The framework relies on the correlation between the therapeutic claims of herbal medicine and the scientific evidence backing them up: the greater the claims made regarding medicinal benefits, the more evidence is required to substantiate its efficacy and safety. This regulatory framework acknowledges and incorporates traditional knowledge when evaluating herbal medicines, showcasing a balanced approach that values cultural traditions while mandating monographs for traditional herbal medicinal products. Excluding herbal medicines completely limits access to affordable treatment, particularly when they serve as the only alternative for some, and protects consumer autonomy. This EU framework could therefore serve as a practical guidance for the use and regulation of herbal medicines, even outside the EU. In conclusion, it is argued that the same moral imagination and courage shown by regulators in the case of herbal medicines could perhaps be used in the regulatory frameworks of other healthcare products.
RESUMO
Significance: Herbal medicines have a long history of comprehensive cancer treatment through various posttranslational modifications (PTMs). Recently, emerging evidence revealed that dysregulation of reactive oxygen species (ROS) and ROS-regulated signaling pathways influence cancer initiation, growth, and progression in a paradoxical role with either low levels or increasing levels of basal ROS. However, ROS-triggered modifications of target proteins in the face of ROS-mediated signal transduction are not fully understood in the anticancer therapies of herbal medicines. In this review, we briefly introduce the PTM-dependent regulations of herbal medicines, and then focus on the current ideals that targeting ROS-dependent PTMs via antioxidant and redox signaling pathways can provide a promising strategy in herbal-based anticancer effects. Recent Advances: Advanced development in highly sensitive mass spectrometry-based techniques has helped utilize ROS-triggered protein modifications in numerous cancers. Accumulating evidence has been achieved in laboratory to extensively ascertain the biological mechanism of herbal medicines targeting ROS in cancer therapy. Two general mechanisms underlining ROS-induced cell signaling include redox state and oxidative modification of target protein, indicating a new perspective to comprehend the intricate dialogues between herbal medicines and cancer cellular contexts. Critical Issues: Complex components of herbal medicines limit the benefits of herbal-based cancer therapies. In this review, we address that ROS-dependent PTMs add a layer of proteomic complexity to the cancer through altering the protein structure, expression, function, and localization. Elaborating ROS-triggered PTMs implicated in cell signaling, apoptosis, and transcriptional regulation function, and the possible cellular signaling, has provided important information about the contribution of many ROS targeting herbal therapies in anticancer effects. Continued optimization of proteomic strategies for PTM analysis in herbal medicines is also briefly discussed. Future Directions: Rigorous evaluations of herbal medicines and proteomic strategies are necessary to explore the aberrant regulation of ROS-triggered antioxidant and redox signaling contributing to the novel protein targets and herbal-associated pharmacological issues. These efforts will eventually help develop more herbal drugs as modern therapeutic agents.
RESUMO
BACKGROUND: Fatigue is an immune-related adverse event (irAE) associated with immune checkpoint inhibitors (ICIs) used for cancer treatment. Chinese herbal medicines (Ho-zai) are used to treat cancer-related fatigue. However, no interactions between ICIs and Ho-zai have been reported. Herein, we investigated the risk of irAEs associated with the concomitant use of ICIs and Ho-zai. METHODS: We extracted data of patients who used ICI and Ho-zai from the Japanese Adverse Event Reporting Database. The proportional reporting ratio (PRR) was calculated for patients using ICI, Ho-zai, or both. We focused on cases of interstitial lung disease (ILD) and colitis, which were among the most severe cases of irAEs among these patients. The shrinkage method used by the World Health Organization-Uppsala Monitoring Center was used to detect the interactions. RESULTS: Of the 799,670 patients in the database, 77,219, 2060, and 92 were using ICIs, Ho-zai, and combination treatment, respectively. The ILD and colitis groups included 39,388 and 17,522 patients, respectively. ILD signals were detected for both ICIs and Ho-zai. There were 24 cases of patients treated with concomitant ICIs and Ho-zai who developed ILD. For all combinations of all ICIs and all Ho-zai, Ω025 was negative, which suggested no ILD-related interactions. Colitis signals were detected for ICIs except for atezolizumab, avelumab, and durvalumab. There were eight patients treated with concomitant ICI and Ho-zai who developed colitis. For all combinations of all ICIs and all Ho-zai, Ω025 was negative, which suggested no colitis-related interactions. CONCLUSION: To our knowledge, this is the first study to investigate interactions between ICIs and Ho-zai. Signals were detected for ILD in both ICI and Ho-zai groups, and colitis in the ICI group. However, the combined use of these treatments did not increase the risk of irAEs.

An imidacloprid colloidal gold immunochromatographic strip was developed in this work, and systematic analytical conditions were deeply investigated. The test strips were used for rapid screening of imidacloprid residues in Chinese herbal medicines. The performance of the colloidal gold test strips was investigated by using five selected Chinese herbal medicines (malt, Coix seed, lotus seed, dried ginger and honeysuckle). As a result, the developed imidacloprid colloidal gold immunochromatographic test strips could be used for rapid screening of imidacloprid residues in 60 kinds of different herbs (including 26 kinds of root/rhizome medicines, 20 kinds of seed/fruit/pericarp medicines, 11 kinds of flower/leaf/whole herb medicines, and 3 kinds of bark/aboveground issues of herb medicines), and the cut-off value was 50 µg/kg. The development of this method can achieve the goal of on-site, rapid and low-cost screening of imidacloprid residues in different herbs, which is of great significance for the quality assurance of herbs.

RESUMO
Introduction: In recent years, diverse initiatives have been carried out to control the COVID-19 pandemic, ranging from measures restricting social activities to analyzing drugs and vaccines. Studies on herbal medicines are also increasingly conducted in various countries as an adjuvant therapy or supplement. Therefore, this systematic review aimed to investigate the efficacy of herbal medicines analyzed from various countries through clinical trials with the randomized controlled trial method. The outcomes of Length of Stay (LOS), Negative Conversion Time (NCT), and Negative Conversion Rate (NCR) were the main focus. Methods: An extensive review of literature spanning from 2019 to 2023 was carried out using well-known databases including PubMed, Scopus, and Cochrane. The search included relevant keywords such as "randomized controlled trial," "COVID-19," and "herbal medicine." Results: A total of 8 articles were part of the inclusion criteria with outcomes of LOS, NCT, and NCR. In terms of LOS outcomes, all types of herbal medicines showed significant results, such as Persian Medicine Herbal (PM Herbal), Persian Barley Water (PBW), Jingyin Granules (JY granules), Reduning Injection, and Phyllanthus emblica (Amla). However, only JY granules showed significant results in NCR outcome, while JY granules and Reduning Injection showed significant results in reducing NCT. Conclusion: These findings enrich our understanding of the potential benefits of herbal medicines in influencing LOS, NCR and NCT parameters in COVID-19 patients. Herbal medicines worked to treat COVID-19 through antiviral, anti-inflammatory, and immunomodulatory mechanisms.
RESUMO
Purpose: Traditional herbal medicines (THMs) are widely used in Sudan, but there is scarcity of research on pharmacy students' attitudes and utilization of THMs. This study aims to assess the attitudes and practices of pharmacy students toward THM. Methods: A descriptive cross-sectional study was conducted among randomly selected undergraduate pharmacy students at the University of Khartoum (Sudan). Data were collected using a validated self-administered questionnaire adapted from previous studies. A statistical package for the social sciences was used for data analysis. Results: Among the 264 respondents, the average age was 21.8 years, and 84.8% of them were females. Nearly 85% of respondents were residents of Khartoum. The overall respondent's attitudes towards THMs were positive, it ranged from high (19.7%), moderate (79.9%). About 87.8% of respondents are interested in learning more about THMs. In addition, 36.4%, and 50.4% of respondents strongly agreed or agreed that THMs should be officially licensed and controlled. A 17.8% and 63.3% of respondents, respectively, reported using traditional herbal remedies either always or occasionally. Supermarkets (35.2%) and friends/family (36.4%) were the main sources of THMs for the participants, and oral administration was the most used route (87.1%). More than 90% of respondents said they would suggest THMs to others, and the most common justifications for doing so were their accessibility (46.6%) and affordability (16.3%). The most widely used herbs were Mentha spicata, Zingiber officinale, Acacia nilotica, Hibiscus sabdariffa, and Syzygium aromaticum. Data revealed a significant association between attitude levels and respondents' gender (p=0.046), year of study (p=0.000), and residence (p=0.017). Conclusion: Most undergraduate pharmacy students had a positive attitude and utilized THMs. Development of effective educational initiatives, research, and regulations are recommended to ensure the appropriate utilization of traditional herbal remedies.
RESUMO
Mold contamination poses a significant challenge in the processing and storage of Chinese herbal medicines (CHM), leading to quality degradation and reduced efficacy. To address this issue, we propose a rapid and accurate detection method for molds in CHM, with a specific focus on Atractylodes macrocephala, using electronic nose (e-nose) technology. The proposed method introduces an eccentric temporal convolutional network (ETCN) model, which effectively captures temporal and spatial information from the e-nose data, enabling efficient and precise mold detection in CHM. In our approach, we employ the stochastic resonance (SR) technique to eliminate noise from the raw e-nose data. By comprehensively analyzing data from eight sensors, the SR-enhanced ETCN (SR-ETCN) method achieves an impressive accuracy of 94.3%, outperforming seven other comparative models that use only the response time of 7.0 seconds before the rise phase. The experimental results showcase the ETCN model's accuracy and efficiency, providing a reliable solution for mold detection in Chinese herbal medicine. This study contributes significantly to expediting the assessment of herbal medicine quality, thereby helping to ensure the safety and efficacy of traditional medicinal practices.
RESUMO
Peptidyl arginine deiminase 4 (PAD4) is a promising target for the treatment of metabolic diseases associated with autoimmune and central nervous system disease. By now there are limited numbers of PAD4 inhibitors, and no one is ready for clinical use. This study aims to find efficient and specific PAD4 inhibitors from traditional herbal medicines and to investigate their inhibitory mechanisms. The inhibitory effects of forty-eight extracts from sixteen traditional herbal medicines which are widely used in traditional herbal medicines were investigated. Salvia miltiorrhiza was found to have the most potent PAD4 inhibitory activity. After that, a practical bioactivity-guided fractionation coupling with a chemical profiling strategy was used to identify the fractions from Salvia miltiorrhiza with strong PAD4 inhibition activity, and the major constituents in these bioactive fractions were characterized by LC-MS/MS. Seven compounds were found to have inhibition on PAD4 with IC50 values ranging from 33.52 µM to 667 µM, in which salvianolic acid A showed the most potent inhibitory activity, with an IC50 value of 33.52 µM. Inhibition kinetic analyses indicated that salvianolic acid A effectively inhibited PAD4 in a mixed inhibitory manner, and computer simulation analyses demonstrated that salvianolic acid A binds to PAD4 mainly using hydrogen bonding. Overall, our results suggest that salvianolic acid A from Salvia miltiorrhiza is a potent inhibitor of PAD4, and that salvianolic acid A can be used as a promising lead compound for the development of more potent PAD4 inhibitors.

Traditional herbal medicines (THMs) have long been in use worldwide and are considered safe for use as tonics or complementary treatments for many diseases. Advanced quality control methods for THMs are required in the regulatory framework of modern medicines. In this study, an ultra-high performance liquid chromatography-tandem mass spectrometry assay was established for the simultaneous determination of 22 marker compounds in Ojeoksan (OJS), which is composed of 15 herbal substances. All marker compounds were analyzed within 20â¯min and successfully identified via scheduled multiple reaction monitoring. The method validation revealed excellent performance characteristics of the method such as specificity, linearity, sensitivity, precision, and accuracy, demonstrating its suitability for intended use. The developed method was applied to samples of commercial OJS tablet and soft-extract dosage forms. The 14 marker compounds corresponding to 12 component herbal substances were determined in the samples; ephedirine, albiflorin, paeoniflorin, ferulic acid, hesperidine, neohesperidin, cinnamic acid, platycodin D, 6-gingerol, atractylenolide III, glycyrrhizin, honokiol, decursin, and magnolol. A fast and easy assay method with sufficient discrimination power was established. As a novel assay, this method can contribute to the quality control of OJS products.

Scrophularia ningpoensis Hemsl. holds a prominent place among Chinese medicinal herbs. Assessing the soil-plant system of its origin is crucial for ensuring medication safety. Although some trace elements are essential for the normal functioning of living organisms, exposure to higher concentrations is harmful to humans, so in order to assess the possible health risk of trace elements in the soil-plant system of Scrophularia ningpoensis Hemsl. origin for human assessment, we used non-carcinogenic risk (HI) and carcinogenic risk (CR) for their evaluation. In this paper, the following trace elements were studied in the soil-Scrophularia ningpoensis Hemsl. system: manganese (Mn), iron (Fe), cobalt (Co), zinc (Zn), selenium (Se), molybdenum (Mo), arsenic (As) and lead (Pb). Correlation and structural equation analyses showed that the effect of soil in the root zone on the plant was much greater than the effect of soil in the non-root zone on the plant. The single-factor pollution index (Pi) showed that the soil in the production area of Scrophularia ningpoensis Hemsl. was polluted to a certain extent, notably with Pb showing the highest average Pi values of 0.94 and 0.89 in the non-root and root zones, respectively. Additionally, the Nemerow composite pollution indices (PN) for both zones indicated an alert range. Regarding health risks, exposure to soil in the non-root zone posed higher non-carcinogenic risk (HI) and carcinogenic risk (CR) compared to the root zone, although neither zone presented a significant carcinogenic risk. The potential non-carcinogenic risk (HI) and carcinogenic risk (CR) from consuming Scrophularia ningpoensis Hemsl. leaves and stems were more than ten times higher than that of roots. However, the carcinogenic risk (CR) values for both the soil and plant of interest in the soil- Scrophularia ningpoensis Hemsl. system did not exceed 10-4, and therefore no significant carcinogenic risk existed.
RESUMO
Microbial resource influences the life activities of medicinal plants from several perspectives. Endophytes, rhizosphere microorganisms, and other environmental microorganisms play essential roles in medicinal plant growth and development, plant yield, and clinical efficacy. The microbiota can influence the biosynthesis of active compounds in medicinal plants by stimulating specific metabolic pathways. They induce host plants to improve their resistance to environmental stresses by accumulating secondary metabolites. Microorganisms can interact with their host plants to produce long-term, targeted selection results and improve their ability to adapt to the environment. Due to the interdependence and interaction between microorganisms and medicinal plants, Chinese herbal medicines (CHMs) quality is closely related to the associated microorganisms. This review summarizes the relationship between medicinal plants and their associated microorganisms, including their species, distribution, life activities, and metabolites. Microorganisms can aid in quality control, improve the efficacy of medicinal plants, and provide markers for identifying the origin and storage time of CHMs. Therefore, a comprehensive understanding of the relationship between microorganisms and medicinal plants will help to control the quality of CHMs from different perspectives.
