Mitigation of cisplatin-induced hepatotoxicity by Salvia officinalis: Attenuation of oxidative damage and inflammation in rats.

Salvia officinalis L., commonly known as sage and belonging to the Lamiaceae family, is a medicinal herb indigenous to the Mediterranean region. It is celebrated for its diverse pharmacological properties and traditional uses in folk medicine, particularly in addressing hepatotoxicity. Cisplatin (Cis), a potent chemotherapeutic agent widely employed in cancer treatment, is recognized for its efficacy but often accompanied by adverse effects, including hepatotoxicity. The aim of this study was to assess whether an ethanolic S. officinalis extract (ESOE) could provide protection against Cis-induced hepatotoxicity in an experimental rat model. The ESOE was prepared using standard extraction techniques, and its chemical constituents were elucidated through UPLC-ESI-MS/MS analysis, revealing the presence of bioactive compounds such as alkaloids, phenolic compounds, and flavonoids, which are associated with various therapeutic effects, including hepatoprotection. Adult male albino rats were allocated into four groups: control, ESOE (250 mg/kg), Cis (7.5 mg/kg), and ESOE (250 mg/kg) + Cis (7.5 mg/kg). The treatment duration lasted 21 days, with Cis administration on the 22nd day. Twenty-four hours post-Cis administration, blood and liver samples were collected for analysis. Cis-induced hepatotoxicity was evidenced by alterations in hematological parameters, including erythrocyte, thrombocyte, leukocyte, and lymphocyte counts, alongside elevated serum levels of liver enzymes (ALT, LDH, AST, ALP, and GGT), indicative of liver damage. Furthermore, Cis exposure resulted in increased hepatic malondialdehyde (MDA) and Nitric oxide (NO) levels, oxidative stress markers, coupled with decreased levels of reduced glutathione (GSH), a non-enzymatic antioxidant, and histopathological changes in liver tissue, characterized by necrosis and inflammation. Additionally, Cis treatment led to elevated levels of 8-hydroxy-2'-deoxyguanosine (8-OH-dG), TNF-α, and IL-6, indicating oxidative stress and inflammation. Remarkably, pretreatment with ESOE ameliorated these Cis-induced hepatotoxic effects, as evidenced by improved hematological parameters, reduced liver enzyme activities, alleviated oxidative stress, and ameliorated histopathological alterations. The observed hepatoprotective effects of ESOE against Cis-induced liver injury may be attributed to its antioxidant and anti-inflammatory properties, highlighting its potential as a natural therapeutic agent in mitigating chemotherapy-associated hepatotoxicity.

Analyzing the impact of pesticides on the indus river: contamination levels in water, sediment, fish, and associated human health risks.

Pesticides are frequently used to protect crop yields and manage malaria vectors; however, their inadvertent transport into aquatic habitats poses a significant concern. Various anthropogenic activities influence the Indus River in Pakistan. This study aimed to assess the presence of eight pesticide residues at three different sites (Kalabagh, Kundian, and Chashma) in water, sediment, and the fish species (Labeo rohita) during both dry and wet seasons to measure the intensity of this pressure. Pesticide analysis was carried out using gas chromatography equipped with an electron capture detector. The results revealed the highest concentrations of pesticides during both dry and wet seasons at all sites, measuring 0.83 and 0.62 µg/l (water), 12.37 and 9.20 µg/g/dw (sediment), and 14.27 and 11.29 µg/g/ww (L. rohita), respectively. Overall, pesticide concentrations were higher in the dry season than in the wet season across all study sites. Based on detection frequency and concentration in both seasons at all sites, dominant pesticides included cypermethrin and carbofuran (in water), as well as endosulfan and cypermethrin (in sediment and fish tissue). Levels of endosulfan and cypermethrin exceeded standard limits. Moreover, principal component analysis (PCA) indicated no correlation among pesticides in fish tissue, sediment, and water. However, pesticides exhibited different behavior in different seasons. Furthermore, endosulfan and triazophos impose great human health risk, as indicated by the THQ value (> 1). The overall HI value was greater for site 1 in the dry season (8.378). The study concluded that the presence of agricultural pesticides in the Indus River poses a risk to aquatic life and has the potential to disrupt the entire food chain. This highlights the importance of sustainable practices for the study area and Pakistan overall agricultural and environmental sustainability. It is further recommended to strengthen regulations for reduced pesticide use and promote eco-friendly pest management.

Sublethal Concentrations of Cadmium and Lead: Effects on Hemato-Biochemical Parameters and Tissue Accumulation in Wallagu attu.

The exposure of fish to heavy metals can significantly impact physiological processes and potentially lead to adverse health effects. This study assesses the effects of exposure to Cd and Pb sublethal concentrations in water on Wallagu attu. A total of 48 fish with an average body weight of 145.5 ± 26 g were distributed among three groups (control, Cd-treated, and Pb-treated) within 60 L fiberglass tanks. They were exposed to 30% sublethal concentrations of Cd and Pb for durations of 1, 15, and 30 days. Following this exposure, an assessment was conducted on metal bioaccumulation and hemato-biochemical responses. Results revealed a significantly (P < 0.05) higher concentration of heavy metals in the fish tissues of metals exposed groups than in the control. The concentration of Cd and Pb increases in fish tissues (kidney > gills > intestine) with exposure time. In most cases, the Pb-exposed group exhibited significantly (P < 0.05) higher concentrations of Pb in different tissues than the Cd-treated group. With extended exposure time, the activities of CAT and SOD show a significant decrease in both Cd and Pb-treated groups. However, the reduction in activities was more pronounced in the Cd-exposed group. On 15 and 30 days, the levels of red blood cells (RBC), hemoglobin (HB), hematocrit (HCT), and total protein (TP) decrease in groups exposed to Cd and Pb. The cortisol and glucose levels exhibit a more noticeable (P < 0.05) increase with prolonged exposure to Cd and Pb than the control group. On day 30, the survival rate decreased more in the Pb-exposed group. The findings of this study indicate that exposure to sublethal doses of Cd and Pb induces stress in Wallagu attu, resulting in rapid changes in specific hemato-biochemical parameters.

Fumaria indica (Hausskn.) Pugsley Hydromethanolic Extract: Bioactive Compounds Identification, Hypotensive Mechanism, and Cardioprotective Potential Exploration.

Fumaria indica (Hausskn.) Pugsley (FIP), a member of the Papaveraceae family, has a documented history of use in traditional medicine to treat cardiovascular ailments, particularly hypertension, and has shown substantial therapeutic efficacy among native cultures worldwide. However, the identification of bioactive compounds and the mechanism of hypotensive effect with the cardioprotective potential investigations are yet to be determined. The study aimed to identify bioactive compounds, explore the hypotensive mechanism and cardioprotective potential, and assess the safety of Fumaria indica (Hausskn.) Pugsley hydromethanolic extract (Fip.Cr). LC ESI-MS/MS analysis was performed to identify the bioactive compounds. In vitro experiments were conducted on isolated rat aorta and atria, and an in vivo invasive BP measurement model was used. Acute and subacute toxicities were assessed for 14 and 28 days, respectively. Isoproterenol (ISO) was used to develop the rats' myocardial infarction damage model. The mRNA levels of NLRP3 inflammasome and the abundance level of Firmicutes and Lactobacillus were measured by qRT-PCR. The hypotensive effect of FIP bioactive compounds was also investigated using in silico methods. Fip. Cr LC ESI-MS/MS analysis discovered 33 bioactive compounds, including alkaloids and flavonoids. In isolated rat aorta, Fip.Cr reversed contractions induced by K+ (80 mM), demonstrating a calcium entry-blocking function, and had a vasorelaxant impact on phenylephrine (PE) (1 µM)-induced contractions unaffected by L-NAME, ruling out endothelial NO participation. Fip.Cr caused negative chronotropic and inotropic effects in isolated rat atria unaffected by atropine pretreatment, eliminating cardiac muscarinic receptor involvement. Safety evaluation showed no major adverse effects. In vivo, invasive BP measurement demonstrated a hypotensive effect comparable to verapamil. Fip.Cr protected the rats from ISO-induced MI interventions significantly in biometrical and cardiac serum biochemical indicators and histological examinations by reducing inflammation via inhibiting NLRP3 inflammasome and elevating Firmicutes and Lactobacillus levels. The network pharmacology study revealed that the FIP hypotensive mechanism might involve MMP9, JAK2, HMOX1, NOS2, NOS3, TEK, SERPINE1, CCL2, and VEGFA. The molecular docking study revealed that FIP bioactive compounds docked better with CAC1C_ HUMAN than verapamil. These findings demonstrated that Fip.Cr's hypotensive mechanism may include calcium channel blocker activity. Fip.Cr ameliorated ISO-induced myocardial infarction in rats by attenuating inflammation, which might be via inhibiting NLRP3 inflammasome and may prove beneficial for treating MI.

A step towards tuning the jute fiber structure and properties by employing sodium periodate oxidation and coating with alginate.

This paper outlines a novel simple protocol for tuning the structure and properties of jute using sodium periodate (NaIO4) oxidation and coating with alginate. When compared to the raw jute, fabrics oxidized with a 0.2 or 0.4 % NaIO4 solution for 30-120 min exhibited an increased aldehyde group content (0.185 vs. 0.239-0.398 mmol/g), a significantly increased negative zeta potential (from -8.57 down to -20.12 mV), a slight disruption of fiber crystallinity, 15.1-37.5 % and 27.9-49.8 % lower fabric maximum force and stiffness, respectively. Owing to the removal of hydrophobic surface barrier, decreased crystallinity index and the presence of micropores on the fabrics' surfaces, oxidized fabrics have a 22.3-29.6 % improved ability for moisture sorption compared to raw fabric. Oxidized fabrics characterized by very long wetting times and excellent antioxidant activities (> 98 %), can find applications as hydrophobic packaging materials. To further extend the utilization of jute in biocarpet engineering such as water-binding geo-prebiotic supports, oxidized fabrics were coated with alginate resulting in 7.9-24.9 % higher moisture sorption and 352-660 times lower wetting times than their oxidized counterparts. This modification protocol has never been applied to lignocellulosic fibers and sheds new light on obtaining jute fabrics with tuned structure and properties intended for various applications.

Phytosynthesized Iron Oxide Nanoparticles Using Aqueous Extract of Saccharum arundinaceum (Hardy Sugar Cane), Their Characterizations, Antiglycation, and Cytotoxic Activities.

The goal of the current study is to achieve plant-mediated synthesis of iron oxide nanoparticles (Fe2O3 NPs). The plant extract of Saccharum arundinaceum was used as a reducing and stabilizing agent for the synthesis of Fe2O3 NPs. Different techniques such as energy-dispersive X-ray analysis (EDX), X-ray diffraction (XRD), scanning electron microscopy (SEM), Fourier-transform infrared spectroscopy (FT-IR), and UV-visible spectroscopy (UV-vis) were used to characterize the synthesis of Fe2O3 NPs. UV-visible spectroscopy verified the synthesis of Fe2O3 NPs using a surface plasmon resonance peak at a wavelength of 370 nm. SEM analysis specifies the spherical morphology of the synthesized nanoparticles with a size range between 30 and 70 nm. The reducing and capping materials of Fe2O3 NPs were revealed by FT-IR analysis based on functional group identification. The plant extract contained essential functional groups, such as C-H, C-O, N-H, -CH2, and -OH, that facilitate the green synthesis of Fe2O3 NPs. The EDX analysis detected the atomic percentage with the elemental composition of Fe2O3 NPs, while the XRD pattern demonstrated the crystallinity of Fe2O3 NPs. Furthermore, the synthesized Fe2O3 NPs showed potential antiglycation activity under in vitro conditions, which was confirmed by the efficient zone of inhibition on glycation of bovine serum albumin/glucose (BSA-glucose) in the order <100 < 500 < 1000 µg/mL, which revealed that Fe2O3 NPs showed significant antiglycation activity. Additionally, the cytotoxic activity against brain glioblastoma cells was assessed using the MTT assay, which exhibited diminished cytotoxic activity at concentrations lower than 300 µg/mL. Thus, we assumed that the resulting Fe2O3 NPs are a good option for use in drug delivery and cancer treatments.

Impact of a mobile-app assisted self-management educational intervention on the scores of asthma control test (ACT) questionnaire among young asthmatic patients.

BACKGROUND: Mobile phone apps have reached almost all sectors of everyday modern human life, including health promotion and patient education intervention. Regarding asthma self-management programs, apps are considered to be a potential learning medium for patients with asthma, especially young patients, due to their effectiveness in improving patients' knowledge and, consequently, the level of asthma control. OBJECTIVE: The aim of this study was to evaluate the effectiveness of the AsmaDroid® mobile app, as compared with conventional educational methods, as a self-management educational intervention tool for improving asthma control among young patients. METHODS: To determine the app's effectiveness, the study involved 140 participants from various backgrounds and applied a quasi-experimental method using a two-group pretest and posttest with a control group design. Specifically, the treatment groups received the AsmaDroid® app as a learning medium, while the control groups used conventional methods (e.g., books, posters, videos, and social media). Before and after a 4-week intervention period, all the participants of both groups were asked to complete the Asthma Control Test (ACT) questionnaire. RESULTS: The results of this study revealed a significant difference of +1.4 (p < 0.0001) in the pretest and posttest scores of the ACT questionnaire from the intervention group, while no difference was found in the control group. CONCLUSIONS: Therefore, this study concluded that mobile app-assisted self-management educational intervention significantly improved the scores of the ACT questionnaire among young asthmatic patients.

Sustainable Dyeing and Functionalization of Different Fibers Using Orange Peel Extract's Antioxidants.

A diluted ethanol orange peel extract was used for sustainable dyeing and functionalization of different fabrics. The extract analysis was performed using UPLC-ESI-MS/MS; its total flavonoid (0.67 g RE/100 g d.w.) and antioxidant (2.81 g GAE/100 g d.w.) contents and antioxidant activity (IC50 of 65.5 µg/mL) were also determined. The extract dyeing performance at various dyebath pH values was evaluated using multifiber fabric. Among six fabrics, extract possessed the ability for dyeing wool, polyamide, and cellulose acetate (at pH 4.5), which color strength (K/S) values increased after washing (9.7-19.8 vs. 11.6-23.2). Extract:water ratio of 20:35 (v/v) was found to be sufficient for achieving satisfactory K/S values (i.e., 20.17, 12.56, and 10.38 for wool, polyamide, and cellulose acetate, respectively) that were slightly changed after washing. The optimal dyeing temperatures for wool, polyamide, and cellulose acetate are 55, 35, and 25 °C, while the equilibrium dye exhaustion at those temperatures was achieved after 45, 120, and 90 min, respectively. The color coordinate measurements revealed that wool and polyamide fabrics are yellower than cellulose acetate, while, compared to polyamide and cellulose acetate, wool is redder. Possible interactions between selected fabrics and extract compounds are suggested. All fabrics possessed excellent antioxidant activity (88.6-99.6%) both before and after washing. Cellulose acetate provided maximum bacterial reduction (99.99%) for Escherichia coli, and Staphylococcus aureus, which in the case of Staphylococcus aureus remained unchanged after washing. Orange peel extract could be used for simultaneous dyeing and functionalization of wool and polyamide (excellent antioxidant activity) and cellulose acetate (excellent antioxidant and antibacterial activity) fabrics.

The Biogenically Efficient Synthesis of Silver Nanoparticles Using the Fungus Trichoderma harzianum and Their Antifungal Efficacy against Sclerotinia sclerotiorum and Sclerotium rolfsii.

Silver nanoparticles (AgNs) are known as a promising alternative tool to control fungal diseases. AgNs were biologically synthesized using Trichoderma harzianum filtrate as an ecofriendly approach. The presence of AgNs was confirmed by changing the color to brown, followed by UV-Vis spectroscopy, transmission electron microscopy (TEM), and Energy-dispersive spectra (EDS). TEM studies showed that the size of AgNs average was 31.13 nm and the shape was spherical. In vitro assays of AgNs showed a significant inhibitory effect on the growth of Sclerotinia sclerotiorum (S. sclerotiorum) and Sclerotium rolfsii (S. rolfsii). The percentage inhibition on mycelial linear growth, dry weight, and sclerotia formation of S. sclerotiorum and S. rolfsii at 100-L were 87.8, 82.7, 96.4, 52.8, 55.1, and 85.4%, respectively. The obtained results suggested that the biosynthesized AgNs have antifungal activity against S. sclerotiorum and S. rolfsii. Foliar spray of bean and sunflower plants with AgNs caused a decrease in disease severity, which promoted the plant protection against S. sclerotiorum and S. rolfsii, respectively. Substantially, this study will extend our understanding of the AgNs antifungal action for suppressing fungal diseases.

Hematoprotective effects and antioxidant properties of ß-glucan and vitamin C against acetaminophen-induced toxicity: an experimental study in rats.

Acetaminophen is widely used as an over-the-counter analgesic and antipyretic drug. The aim of the present study was to investigate the pro-oxidative effects of acetaminophen (300 mg/kg/day i.p.) and antioxidative effects of ß-glucan (4 mg/kg/day i.p.) and/or vitamin C (100 mg/kg/day i.p.) on the blood parameters of treated rats. After 3 days of treatment, hematological and parameters of redox status were measured. Exposure of rats to acetaminophen caused significant changes in some hematological parameters and the glutathione redox cycle, leading to an increased concentration of oxidative stress parameters and the formation of lipid peroxidation, while the activities of antioxidant enzymes were decreased. Administration of ß-glucan and/or vitamin C reduced lipid peroxidation and restored the levels of examined hematological and oxidative stress parameters and improved the activities of antioxidant enzymes. Obtained results demonstrated that acetaminophen has significant pro-oxidative effects and may disrupt redox balance in blood of rats, while the combination of ß-glucan and/or vitamin C amplified the antioxidant defense potential and exhibited a strong hematoprotective activity against acetaminophen-induced toxicity. Therefore, ß-glucan and vitamin C co-treatment may be a promising therapeutic option for the treatment of acute acetaminophen hematotoxicity.

Evaluation of Toxic Effects of Novel Platinum (IV) Complexes in Female Rat Liver: Potential Protective Role of Resveratrol.

The use of cisplatin in chemotherapy may provoke a deteriorating impact in many vital organs, suggesting the need for more selective derivatives and effective protective cotreatments. This study assesses the effects of three novel Pt(IV) complexes containing ethyl-, propyl- and butyl-esters of the ethylenediamine-N, N'-di-S, S- (2,2'-dibenzyl) acetic acid on liver injury markers, redox parameters, and cell morphology of female rat liver tissue in comparison to cisplatin. In addition, the study evaluates the possible protective effects of resveratrol as well. The rats were divided into ten groups and were administered intraperitoneally with a single dose of cisplatin (7.5 mg/kg) or Pt(IV) complexes (10 mg/kg) and/or resveratrol (25 mg/kg). All treatments caused changes in body weight, food intake, and liver/bw ratio. Acute treatment with novel complexes decreased the levels of TB and TP while elevated the activity of ALT, AST, GGT, ALP which subsequently indicated on the liver damage. All three complexes significantly reduced the levels of LPO, O2.-, NO2- and activity of CAT, while increasing the activity of SOD, GSH-Px, GR, GST, and level of GSH, implying that these compounds could provoke redox balance disruption in liver cells. Moreover, according to the histopathological observations, the novel Pt(IV) complexes exerted stronger hepatotoxicity than cisplatin. Possible protective effects of resveratrol were not detected and even combined with examined compounds it abolished the activity of the antioxidative system of the liver cells causing more intense toxicity. Further investigation is required to elucidate the effects of Pt-based drugs and resveratrol in the estradiol-rich environment of female rats as well their influence on male rats' tissues.

Role of selenium and vitamin C in mitigating oxidative stress induced by fenitrothion in rat liver.

Excessive use of organophosphate insecticides, including fenitrothion (FNT) can cause detrimental consequences in non-target organisms. Selenium (Se) and vitamin C (Vit C) possess protective abilities against various toxic compounds due to their antioxidative properties. Accordingly, the aim of the present study was to examine the possible ameliorative effects of Se and Vit C in hepatotoxicity induced by FNT. For the purpose of this study, male Wistar albino rats were divided into control and groups treated with Se (0.5 mg/kg b.w, as Na2SeO3) and Vit C (100 mg/kg b.w), FNT (20 mg/kg b.w) and FNT in cotreatment with Se and Vit C for 30 days. The current data showed a reduction in absolute and relative liver weight after FNT administration. Increased activities of liver enzymes (AST, ALT, ALP, LDH and GGT) indicated liver damage. FNT alone caused significant alterations in biochemical parameters (glucose and total bilirubin). Elevation in LPO level along with decreased activities of antioxidant enzymes (SOD, CAT, GSH-Px) and GSH content reflected the presence of oxidative stress. Coadministration of FNT with Se and Vit C exhibited hepatoprotective role confirmed by reduction of oxidative stress levels and restoration in the values of examined parameters. Because of their beneficial effects, Se and Vit C may be used in reducing injuries caused by pesticides.

The ameliorating effects of selenium and vitamin C against fenitrothion-induced blood toxicity in Wistar rats.

Fenitrothion is widely used organophosphate pesticide in agriculture and health programs, but besides, it causes several toxic effects. The present study was designed to evaluate the possible protective effects of selenium (0.5mg/kg b.w.) and vitamin C (100mg/kg b.w) on altered haematological, biochemical and oxidative stress parameters in the blood of rats orally treated with fenitrothion (20mg/kg b.w) for 30days. Fenitrothion caused changes in body weight, food and water intake, and some haematological and biochemical parameters. Fenitrothion altered the glutathione redox status (GSH and GSSG) and decreased activity of antioxidant enzymes (GSH-Px, GST, SOD and CAT), leading to a lipid peroxidation. Selenium and vitamin C, by improving the activity of antioxidants, reduced oxidative stress and a lipid peroxidation, maintaining the values of examined parameters to optimal levels. Therefore, selenium and vitamin C could be useful in providing protection of exposed non-target organisms including people from fenitrothion.
