Objective: An imbalance between the generation of reactive oxygen species (ROS) and the body's antioxidant defense mechanisms is believed to be a critical factor in the development of schizophrenia (SCZ) like neurological illnesses. Understanding the roles of ROS in the development of SCZ and the potential activity of natural antioxidants against SCZ could lead to more effective therapeutic options for the prevention and treatment of the illness. Methods: SCZ is a mental disorder characterised by progressive impairments in working memory, attention, and executive functioning. In present investigation, we summarized the experimental findings for understanding the role of oxidative stress (OS) in the development of SCZ and the potential neuroprotective effects of natural antioxidants in the treatment of SCZ. Results: Current study supports the use of the mentioned antioxidant natural compounds as a potential therapeutic candidates for the treatment of OS mediated neurodegeneration in SCZ. Discussion: Elevated levels of harmful ROS and reduced antioxidant defense mechanisms are indicative of increased oxidative stress (OS), which is associated with SCZ. Previous research has shown that individuals with SCZ, including non-medicated, medicated, first-episode, and chronic patients, exhibit decreased levels of total antioxidants and GSH. Additionally, they have reduced antioxidant enzyme levels such as catalase (CAT), glutathione (GPx), and, superoxide dismutase (SOD) and lower serum levels of brain-derived neurotrophic factor (BDNF) in their brain tissue. The mentioned natural antioxidants may assist in reducing oxidative damage in individuals with SCZ and increasing BDNF expression in the brain, potentially improving cognitive function and learning ability.

This study aims to investigate selected medicinal plants' anti-oxidative and antihyperglycemic activities to develop an effective remedy for lowering blood glucose levels and/or reducing diabetes complications. Thai medicinal plants, reported to have blood sugar-lowering effects, were selected for the study: Coccinia grandis, Gymnema inodorum, Gynostemma pentaphyllum, Hibiscus sabdariffa, Momordica charantia, Morus alba, and Zingiber officinale. Each species was extracted by Soxhlet's extraction using ethanol as solvent. The ethanolic crude extract of each species was then evaluated for its phytochemicals, anti-oxidant, and antihyperglycemic activities. The results showed that the extract of Z. officinale gave the highest values of total phenolic and total flavonoid content (167.95 mg gallic acid equivalents (GAE)/g and 81.70 mg CE/g, respectively). Anti-oxidant activity was determined using DPPH and ABTS radical scavenging activity. Among the ethanolic extracts, Z. officinale exhibited the highest anti-oxidant activity with IC50 values of 19.16 and 8.53 µg/mL, respectively. The antihyperglycemic activity was assessed using α-glucosidase inhibitory and glucose consumption activities. M. alba and G. pentaphyllum demonstrated the highest α-glucosidase inhibitory activity among the ethanolic extracts, with IC50 values of 134.40 and 329.97 µg/mL, respectively. Z. officinale and H. sabdariffa showed the highest percentage of glucose consumption activity in induced insulin-resistant HepG2 cells at a concentration of 50 µg/mL with 145.16 and 107.03%, respectively. The results from α-glucosidase inhibitory and glucose consumption activities were developed as an effective antihyperglycemic remedy. Among the remedies tested, the R1 remedy exhibited the highest potential for reducing blood glucose levels, with an IC50 value of 122.10 µg/mL. Therefore, the R1 remedy should be further studied for its effects on animals. [ABSTRACT FROM AUTHOR]

In this study was investigated the effects of extract of the Juncus inflexus subsp. inflexus (JI) plant on thioacetimide (TAA)‐induced liver damage. Six experimental groups were formed using 42 8–12‐weeks old Sprague dawley male rats, with seven experimental animals per group. Liver tissue sections were examined by staining with hematoxylin eosin (H‐E), periodic acid schiff (PAS) and caspase‐3. On the other hand, the tissue homogenates were analyzed by enzyme linked immunosorbent assay (ELISA), in terms of malondialdehyde (MDA) and glutathione (GSH). Compared to other groups, it was observed that the MDA rose significantly in the TAA group and that the GSH fell and that the expression of the caspase‐3 was significantly increased. On the other hand, it was found that lipid peroxidation decreased significantly in the TAA + JI group when compared to JI + TAA group. Also, to see the antioxidant properties of the plant in detail, molecular dynamic simulations were done. The antioxidant property of 59.16% in extract compounds of JI was theoretically demonstrated. The antioxidant activity of the 10‐methoxy‐nb‐alpha‐methylcorynantheol molecule, which is found at the highest rate in the relevant plant, has been theoretically revealed for the first time. In conclusion, this study has revealed that the extraction obtained from the Juncus inflexus plant has protective and therapeutic properties for the liver. [ABSTRACT FROM AUTHOR]

Massa Medicata Fermentata (MMF) is a naturally fermented product used to treat indigestion and increase stomach activity in traditional medicine. This study examined the ability of the hydrothermal extract of MMF to scavenge free radicals corresponding to biological oxidative stresses, further protecting essential biomolecules. The anti-inflammatory effects of MMF were evaluated in LPS-induced RAW264.7 macrophages and zebrafish. In addition, the effects of MMF on the body mass index (BMI) and cholesterol accumulation in adult zebrafish fed a high-cholesterol diet (HCD) for three weeks were examined. MMF prevented the DNA and lipid damage caused by oxidative stress, inhibited LDL oxidation, and reduced the expression of cytokines and related proteins (MAPK and NFκB), with prominent anti-oxidative pathway (NRF2-HO-1) activation properties. LPS-induced NO production was reduced, and the increase in BMI and TC caused by the HCD diet was suppressed by MMF in zebrafish embryos or adult zebrafish. The bioactive aglycone of quercetin may be contributing to the mechanisms of systemic effects. MMF has excellent antioxidant properties and is useful for improving inflammation status and metabolic profile, thus highlighting its potential as a healthy, functional food. [ABSTRACT FROM AUTHOR]

This article describes the controlled synthesis and characterization of an olefin‐linked oxazolone scaffold compound containing multifunctional groups, including the carbonyl group, imine, and carbon‐carbon double bond. The reaction of the bisoxazolone with aromatic amines led to the ring‐opening of the bisoxazolone into the corresponding bisdiamide derivatives in a short time (average 10 min), resulting in a high yield (>90 %). The compounds were characterized by FT‐IR, 1H‐NMR, 13C‐NMR, and MS. Besides, screened against Escherichia coli, Staphylococcus aureus, and Candida albicans using ciprofloxacin as a standard. All compounds exhibited significant inhibition potency against E. coli, with a lower potency against S. aureus. Compounds 3 a, 3 b, and 3 d showed more reactivity against E. coli, while compound 3 i has the highest activity against S. aureus (MIC=128 μg/mL). Additionally, the antioxidant activity was performed utilizing DPPH radical scavenging activity. The findings indicated that some compounds possessed moderate antioxidant activity in comparison to ascorbic acid as a control. A molecular docking study demonstrated a positive interaction between synthesized compounds and the bacterial DNA gyrase target (PDB ID: 1KZN) in S. aureus. Subsequently, in silico ADME simulations were conducted for all the synthesized compounds, indicating favorable properties in comparison to the established antibiotic ciprofloxacin.

Simple Summary: Natural polyphenols are well-known dietary supplements that have been used for medical purposes for a long time. Consuming foods and beverages of plant origin, especially those rich in polyphenolic compounds, may have chemopreventive and therapeutic effects on cancer due to the health-promoting properties of these compounds. Polyphenols are characterized by high structural diversity, which contributes to their wide range of therapeutic effects, including anti-oxidant and anti-cancer activities. These compounds can modulate the expression and activity of many proteins, including enzymes, and regulate multiple cell signaling pathways. Among the molecular targets of anti-cancer agents are matrix metalloproteinases, particularly metalloproteinase-2 and metalloproteinase-9, and nuclear factor-kappa B. Matrix metalloproteinases can degrade the protein components of the extracellular matrix and play key roles in physiological processes such as tissue repair and morphogenesis, as well as in carcinogenesis and other pathological processes. The inhibition of their synthesis and activity is closely related to a reduction in the metastasis and invasion of cancer cells. This review discusses the current state of knowledge concerning the anti-invasive and anti-metastatic potential of selected polyphenols, with a focus on in vitro and in vivo evidence. Polyphenols are natural compounds found in many plants and their products. Their high structural diversity bestows upon them a range of anti-inflammatory, anti-oxidant, proapoptotic, anti-angiogenic, and anti-metastatic properties, and a growing body of research indicates that a polyphenol-rich diet can inhibit cancer development in humans. Polyphenolic compounds may modulate the expression, secretion, or activity of compounds that play a significant role in carcinogenesis, including type IV collagenases, such as matrix metalloproteinase-2 (MMP-2) and matrix metalloproteinase-9 (MMP-9), by suppressing cellular signaling pathways such as nuclear factor-kappa B. These enzymes are responsible for the degradation of the extracellular matrix, thus promoting the progression of cancer. This review discusses the current state of knowledge concerning the anti-cancer activity of polyphenols, particularly curcumin, resveratrol, epigallocatechin-3-gallate, genistein, and quercetin, with a specific focus on their anti-invasive and anti-metastatic potential, based on the most recent in vitro and in vivo studies. It appears that polyphenols may be valuable options for the chemoprevention and treatment of cancer via the inhibition of MMP-2 and MMP-9 and the suppression of signaling pathways regulating their expression and activity.

Halophilic archaea are a unique group of microorganisms that thrive in high–salt environments, exhibiting remarkable adaptations to survive extreme conditions. Archaeological wood and El–Hamra Lake serve as a substrate for a diverse range of microorganisms, including archaea, although the exact role of archaea in archaeological wood biodeterioration remains unclear. The morphological and chemical characterizations of archaeological wood were evaluated using FTIR, SEM, and EDX. The degradation of polysaccharides was identified in Fourier transform infrared analysis (FTIR). The degradation of wood was observed through scanning electron microscopy (SEM). The energy dispersive X–ray spectroscopy (EDX) revealed the inclusion of minerals, such as calcium, silicon, iron, and sulfur, into archaeological wood structure during burial and subsequent interaction with the surrounding environment. Archaea may also be associated with detected silica in archaeological wood since several organosilicon compounds have been found in the crude extracts of archaeal cells. Archaeal species were isolated from water and sediment samples from various sites in El–Hamra Lake and identified as Natronococcus sp. strain WNHS2, Natrialba hulunbeirensisstrain WNHS14, Natrialba chahannaoensis strain WNHS9, and Natronococcus occultus strain WNHS5. Additionally, three archaeal isolates were obtained from archaeological wood samples and identified as Natrialba chahannaoensisstrain W15, Natrialba chahannaoensisstrain W22, and Natrialba chahannaoensisstrain W24. These archaeal isolates exhibited haloalkaliphilic characteristics since they could thrive in environments with high salinity and alkalinity. Crude extracts of archaeal cells were analyzed for the organic compounds using gas chromatography–mass spectrometry (GC–MS). A total of 59 compounds were identified, including free saturated and unsaturated fatty acids, saturated fatty acid esters, ethyl and methyl esters of unsaturated fatty acids, glycerides, phthalic acid esters, organosiloxane, terpene, alkane, alcohol, ketone, aldehyde, ester, ether, and aromatic compounds. Several organic compounds exhibited promising biological activities. FTIR spectroscopy revealed the presence of various functional groups, such as hydroxyl, carboxylate, siloxane, trimethylsilyl, and long acyl chains in the archaeal extracts. Furthermore, the archaeal extracts exhibited antioxidant effects. This study demonstrates the potential of archaeal extracts as a valuable source of bioactive compounds with pharmaceutical and biomedical applications. [ABSTRACT FROM AUTHOR]

Purpose: To study the effect of evodiamine on the signaling pathway of ROS/ICAM-1/Nrf2 in rats with acetic acid-induced stomach ulcers. Methods: The rats were randomly assigned to five groups containing 10 rats each. Prior to acetic acidinduction of gastric ulcers, omeprazole (4.0 mg/kg/day), low-dose evodiamine (L-EVD, 20 mg/kg/day), and high-dose evodiamine (H-EVD, 40 mg/kg/day) were orally administered to the respective groups for 15 days. Following ulcer induction, the same treatments continued for an additional 7 days, for a total treatment duration of 22 days. The control (0.9 % saline) and acetic acid (model) groups were administered 0.9 % sodium chloride solution (10 mL/kg) for the same period. Thereafter, oxidative stress, inflammatory markers, macroscopic and microscopic evaluations were conducted on the gastric mucosa. Results: The acetic acid group showed significantly higher levels of oxidative and inflammatory markers, as well as damage and degeneration of the gastric mucosa when compared to control group (p < 0.05). However, both low-dose and high-dose evodiamine treatment groups demonstrated significant gastric healing. Administration of low-dose and high-dose evodiamine resulted in significantly lower levels of malondialdehyde (MDA), tumor necrosis factor a (TNF-a), interleukin-1ß (IL-1ß), myeloperoxidase (MPO) and intracellular adhesion molecule-1 (ICAM-1, p < 0.05). Furthermore, evodiamine treatment led to significantly increased levels of glutathione (GSH) and nuclear facterythroid factor 2 (Nrf2). Conclusion: Evodiamine reduces oxidative stress, suppresses inflammatory reactions, and exerts an anti-ulcer effect on acetic acid-induced gastric ulcers in rats by modulating ROS/ICAM-1/Nrf2 signaling pathway. More studies into the integration of evodiamine into conventional pharmaceutical treatments for gastric ulcers should be conducted. [ABSTRACT FROM AUTHOR]

Oxidative stress is implicated in the pathophysiology of several illnesses. Catalase (CAT), an antioxidant enzyme, remains a prime target for oxidative stress related therapies. Unfortunately, the labile nature, difficulty in recovering and reusing, and insufficient delivery systems limit its use in therapy. This study used a simple biomineralization process for the synthesis of vaterite porous calcium carbonate (CaCO 3) microspheres (MS) for the development of cross-linked immobilized (CAT-MS). Scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDX), particle size analysis, and zeta-potential measurements were used for CaCO 3 -MS characterization. CAT was immobilized efficiently with a high immobilization yield (99 %). The immobilized enzyme had a higher Km than free CAT with a 1.7 fold increase in Vmax and Kcat. CAT-MS displayed a longer half-life, efficient reusability, enhanced storage stability, and excellent stability against various denaturants compared to free CAT. Furthermore, CAT-MS demonstrated negligible cytotoxicity in the fibroblast cell line (BJ1), where CAT-MS recorded higher cell viability than free CAT, (p< 0.05) indicating exceptional biocompatibility. This study raises the potential of an eco-friendly approach that enforces wide and safe catalase application in intracellular therapy for treating oxidative stress-associated diseases. [Display omitted] • Catalase-loaded CaCO 3 microspheres (CAT-MS) were synthesized by a modified process. • High immobilization yield and prominent loading efficiency were achieved. • CAT-MS had a longer half-life and enhanced thermal and storage stability. • immobilization improved reusability and stability against various denaturants. • CAT-MS demonstrated high biocompatibility in vitro cell line.

Background: The majority of pregnant women suffer from iron deficiency anemia (IDA). In addition to affecting hematological parameters, IDA disrupts the body’s oxidative balance, which impairs pregnancy outcome. OBJECTIVE: The objective is to determine the impact of orally supplementation of ferrous sulfate on pregnant women with IDA on their antioxidant levels and oxidative stress (OS) status. MATERIALS AND METHODS: This case–control study population comprised 60 pregnant women, divided into two categories: 30 pretreated pregnant women with IDA and 30 posttreatment pregnant women after 6–8 weeks with ferrous sulfate 200 mg daily. We also included 30 nonanemic, nonpregnant women as a healthy control group. We measured the antioxidant parameters: total antioxidant capacity (TAC), superoxide dismutase (SOD), glutathione peroxidase (GPx), and the malondialdehyde (MDA) oxidant parameter for all groups. Results: The results revealed significant decreases in each of hemoglobin (HB), iron, ferritin, TAC, GPx, and SOD, as well as a significant increase in MDA levels (P < 0.000) in the pretreated IDA patients compared to the control group. The oxidant-antioxidant indices TAC, SOD, GPx, and MDA got a lot better after being treated with 200 mg/day of ferrous sulfate for 6–8 weeks. All of the study’s biomarkers showed a positive correlation with the level of HB. Conclusion: Oxidative stress has been associated with iron-deficient anemia. Supplementation with ferrous sulfate 200 mg is necessary for reducing the resulting OS.

Abstract Utilising biofertilizers is a sustainable alternative of integrated nutrient management in plants. Commercialized biofertilizers for non-legumes include Azotobacter and Phosphate Solubilizing Bacteria (PSB), without reported adverse effects on human health, including consumption of raw salad vegetables. However, no commercial biofertilizers for non-legumes are based on rhizobia, despite proven human safety from decades of legume inoculation research. A comparative analysis investigating the yield of tomatoes (Solanum lycopersicum), and content of Lycopene, Vitamin C and antioxidants was undertaken to assess the potential commercial viability of Rhizobium as a biofertilizer for non-leguminous plants. Rhizobium amendment gave a lesser yield of tomatoes (3 ± 1) compared to Azotobacter (4 ± 1), but was better than the control (2 ± 1), and PSB (2 ± 1). It showed highest lycopene content (0.7 ± 0.02 mg/100 g) compared to other amendments. The Vitamin C (32.4 ± 0.01 mg/100 g) with Rhizobium amendment surpassed that of Azotobacter (24.9 ± 0.09 mg/100 g) and control (12.84 ± 0.03 mg/100 g). Antioxidant activity of cherry tomatoes grown in Rhizobium-amended soil, was 1.34 times higher than chemically-fertilized plant yield. This study therefore affirms the suitability of rhizobia as a biofertilizer for stimulating the growth and productivity of non-leguminous plants such as tomato (S. lycopersicum) and its potential to be commercialized for use in non-leguminous plants.

Objective(s): In recent years, microplastics (MPs), which are novel environmental contaminants measuring 5 mm in diameter, have garnered considerable attention. However, information regarding substances that can mitigate the dangers of MPs for animals remains extremely limited. Materials and Methods: Ninety days were devoted to the exposure of mature male mice to royal jelly (RJ) and 2 µm virgin polystyrene microplastics (PS-MPs) in this study. Pre-implantation embryo development; the structure of testis tissue; the gonadosomatic index; sperm parameters; RNA damage in germinal cells; the anti-oxidant capacity of the entire testis; and the activity of anti-oxidant enzymes in serum and testicular tissue, including TAC, SOD dismutase, CAT, GSH, and MDA, histomorphometric indices of the testis (tubular differentiation index, spermatogenesis index, and repopulation index), steroidogenic foci, and the quantity of apoptosis were assessed in the testis, respectively, through the measurement of pro-apoptosis (p53, Bax, and Caspase-3) and anti-apoptosis (Bcl-2) factors, as well as Hsp70 mediator. Results: The results indicate that concurrent administration of RJ can confer a protective effect on mice exposed to microplastics by maintaining the structure of mitochondria and enhancement of the anti-oxidant defense system. Furthermore, RJ co-treatment decreased apoptosis and oxidant/anti-oxidant status, enhanced pre-implantation embryo development, and improved sperm characteristics and RNA damage in germ cells. Conclusion: The data confirm that royal jelly could protect the testis structure against polystyrene microplastic-induced testicular injury through anti-oxidant and anti-apoptotic properties.

Triple-negative breast cancer (TNBC) doesn't have well-defined molecular targets making it unable to treat with chemotherapy also have faster metastatic rate and worse survival rate. In the current study we aim to target TNBC through eco-friendly green synthesized silver nanoparticles having anti-cancer phytoconstituents from the traditional anti-cancer medicinal plant Eclipta alba. Green synthesized silver nanoparticles (AgNPs) are agglomerates of spherical shaped 40-60 nm sized showing characteristic light absorption at 437 nm, banding pattern at 1479, 1285, 1036, and 471 showing and further X-ray diffraction pattern confirm face-centered cubic crystal silver structure exist in the green synthesized silver nanoparticle preparation. Further in vitro anti-oxidant analysis results revealed that green synthesized AgNPs showed 2.6-fold higher anti-oxidant potential (IC50 15.70 g/ml) than that of aqueous plant leaf extract (IC50 39.80 g/ml). In MTT cytotoxicity analysis Eclipta alba plant extract and AgNPs both display dose-dependent cytotoxicity against triple-negative breast cancer cells (MDA-MB-231), although their IC50 values differ substantially, at 105.80 µg/ml and 77.20 g/ml, respectively. Finally, AgNPs from Eclipta alba tested for anti-leishmanial activity and it showed 91.36 ± 1.05 for promastigotes and 76.62 ± 0.95 for amastigotes at the highest dose of 400 g/ml. Altogether present data showed that Eclipta alba leaf extract actively bonded with silver nanoparticles suppresses the MDA-MB-231 cells growth through high antioxidant characters and anti-leishmanial activity. From together we confirm that Eclipta alba was recommended to a future therapeutic drug and agent to control breast cancer in the clinical level. [ABSTRACT FROM AUTHOR]

Cocoa is rich in polyphenols, mainly flavonoids, which correlate with several health benefits mediated by their antioxidant, anti-inflammatory and immunomodulatory properties. Cocoa and chocolate consumption have been reported to impact the regulation of the immune system, both in preclinical studies and in human trials. The mechanisms for immunomodulation can involve different effects of cocoa polyphenols on the immune system, acting as anti-inflammatory, antioxidant and anti-allergic agents, as well as the direct influence of cocoa on innate and acquired immunity, with cytokines production and activation of both lymphocyte-dependent and -independent pathways. Cocoa intake has been also correlated to changes in gut microbiota ecology and composition, also affecting the intestinal immune system. This review summarises the updates of the last two decades on cocoa as immunomodulatory agent and explores the health-related benefits of cocoa and chocolate intake. [ABSTRACT FROM AUTHOR]

Objective(s): Rhabdomyolysis, a potentially life-threatening condition, occurs when myoglobin is released from damaged muscle cells, leading to acute kidney injury (AKI). Alpha lipoic acid (ALA), an organosulfur compound known for its anti-oxidant and anti-inflammatory properties, was examined in this study for its potential impact on rhabdomyolysis-induced AKI in rats. Materials and Methods: Six groups of rats were included in the study, with each group consisting of six rats (n=6): Control, rhabdomyolysis, rhabdomyolysis treated with different doses of ALA (5, 10, and 20 mg/kg), and ALA alone (20 mg/kg) groups. Rhabdomyolysis was induced by intramuscular injection of glycerol on the first day of the experiment, while ALA was administered intraperitoneally for four consecutive days. Renal function parameters, oxidative stress markers, and histological changes in the kidneys were evaluated. Western blot analysis was performed to measure the levels of neutrophil gelatinase-associated lipocalin (NGAL) and tumor necrosis factor-alpha (TNF-α) proteins.Results: A significant increase in serum urea, creatinine, renal malondialdehyde, NGAl, and TNF-α protein levels was observed in glycerol-injected rats. In addition, a significant decrease in glutathione was recorded. Compared to the rhabdomyolysis group, treatment with ALA recovered kidney histological and biochemical abnormalities. Conclusion: Results suggest that rhabdomyolysis-induced AKI is associated with increased oxidative stress and inflammation. Treatment with ALA improved kidney histological abnormalities and reduced oxidative stress markers in rats. Therefore, ALA may have a potential protective effect against rhabdomyolysis-induced AKI.

Diabetic mellitus (DM) is characterized by hyperglycaemia and defective macromolecular metabolism, arising from insulin resistance or lack of insulin production. The present study investigates the potential of artemisinin, a sesquiterpene lactone isolated from Artemisia annua, to exert anti-diabetic and antioxidant effects through modulation of the phosphoinositide 3-kinase (PI3K)/protein kinase B (AKT) signalling pathway. Our computational analyses demonstrated a high binding affinity of artemisinin with proteins belonging to the PI3K/AKT signalling cascade. α-Amylase and α-glucosidase studies revealed a notable increase in inhibition percentages with artemisinin treatment across concentrations ranging from 10 to 160 µM. A similar significant (p < 0.05) dose-dependent inhibition of free radicals was observed for the in vitro anti-oxidant assays. Further, toxicological profiling of artemisinin in the in vivo zebrafish embryo-larvae model from 4 to 96 h post-fertilization (hpf) did not exhibit any harmful repercussions. In addition, gene expression investigations confirmed artemisinin's potential mechanism in modulating hyperglycaemia and oxidative stress through the regulation of the PI3K/AKT pathway. Overall, our investigation suggests that artemisinin can be used as a therapeutic intervention for diabetes and oxidative stress, opening up opportunities for future investigation in clinical settings.

Milk, on account of its abundant protein content, is recognized as a vital source of bioactive substances. In this study, the bioactive ingredients in milk were obtained by a combination of protease hydrolysis and fermentation with Lactobacillus plantarum. The compositions of protease hydrolysate (PM) and fermentation supernatant (FM) were determined, and their anti-oxidant and anti-bacterial activities were evaluated. Using LC-MS/MS, the molecular weights and sequences of the peptides were characterized, among which a total of 25 bioactive peptides were identified. The DPPH radical scavenging results demonstrated that FM exhibited an enhanced anti-oxidant capacity compared to PM. The bacterial survival rate results revealed that FM had a remarkable anti-bacterial ability compared to PM. Additionally, the anti-bacterial component and potential anti-bacterial mechanisms were determined. The results of cytoplasmic membrane depolarization, cell membrane permeability, and morphological observation indicated that FM could interact with bacterial membranes to achieve its anti-bacterial effect. These findings suggested that FM, as a bioactive substance of natural origin, holds potential applications in the functional food, pharmaceutical, and cosmetic industries. [ABSTRACT FROM AUTHOR]

The present study aimed to study the effect of caffeic acid (CA) on diabetic cardiac complications associated with Type-I diabetes mellitus (DM) in rats. Type-I DM in rats was induced by streptozotocin (STZ) injection once only [45 mg/kg, i.v]. The animals were divided into four groups, and treatment was given for 8 weeks with CA [25 mg/kg, PO and 50 mg/kg, PO] in two specified diabetic groups. After 8 weeks, serum and urine were collected and various serum and urine parameters were estimated. Animals were then sacrificed, and their hearts were removed for estimation of histopathological and oxidative parameters. STZ-induced diabetic rats showed significantly decreased albumin levels and increased MDA, collagen, and decreased activates of SOD and glutathione in their diabetic hearts. In the diabetic control, rats showed significantly increased serum cardiac parameters of CK, CRP, and LDH and also increased serum lipid profile parameters of LDL, cholesterol, and TG. Treatment with CA 25 mg/kg and 50 mg/kg showed significantly decreased CK, CRP, and LDH in diabetic-treated rats and decreased UA. Additionally, significantly decreased MDA, collagen, and increased activities of SOD and GSH were seen in the diabetic-treated rats. Histopathological findings also supported the beneficial effect of CA on the left ventricle of the heart. The present study revealed that the beneficial effects of CA on diabetic cardiovascular complications may be via anti-oxidative and anti-inflammatory actions. [ABSTRACT FROM AUTHOR]

Objective(s): Rhabdomyolysis, a potentially life-threatening condition, occurs when myoglobin is released from damaged muscle cells, leading to acute kidney injury (AKI). Alpha lipoic acid (ALA), an organosulfur compound known for its anti-oxidant and anti-inflammatory properties, was examined in this study for its potential impact on rhabdomyolysis-induced AKI in rats. Materials and Methods: Six groups of rats were included in the study, with each group consisting of six rats (n=6): Control, rhabdomyolysis, rhabdomyolysis treated with different doses of ALA (5, 10, and 20 mg/kg), and ALA alone (20 mg/kg) groups. Rhabdomyolysis was induced by intramuscular injection of glycerol on the first day of the experiment, while ALA was administered intraperitoneally for four consecutive days. Renal function parameters, oxidative stress markers, and histological changes in the kidneys were evaluated. Western blot analysis was performed to measure the levels of neutrophil gelatinase-associated lipocalin (NGAL) and tumor necrosis factor-alpha (TNF-α) proteins. Results: A significant increase in serum urea, creatinine, renal malondialdehyde, NGAl, and TNF-a protein levels was observed in glycerol-injected rats. In addition, a significant decrease in glutathione was recorded. Compared to the rhabdomyolysis group, treatment with ALA recovered kidney histological and biochemical abnormalities. Conclusion: Results suggest that rhabdomyolysis-induced AKI is associated with increased oxidative stress and inflammation. Treatment with ALA improved kidney histological abnormalities and reduced oxidative stress markers in rats. Therefore, ALA may have a potential protective effect against rhabdomyolysis-induced AKI.

The endoplasmic reticulum (ER) is an intracellular organelle that contributes to the folding of proteins and calcium homeostasis. Numerous elements can disrupt its function, leading to the accumulation of proteins that are unfolded or misfolded in the lumen of the ER, a condition that is known as ER stress. This phenomenon can trigger cell death through the activation of apoptosis and inflammation. Glucoraphanin (GRA) is the predominant glucosinolate found in cruciferous vegetables. Various mechanical and biochemical processes activate the enzyme myrosinase, leading to the hydrolysis of glucoraphanin into the bioactive compound sulforaphane. Sulforaphane is an organosulfur compound that belongs to the isothiocyanate group. It possesses a wide range of activities and has shown remarkable potential as an anti-inflammatory, antioxidant, antitumor, and anti-angiogenic substance. Additionally, sulforaphane is resistant to oxidation, has been demonstrated to have low toxicity, and is considered well-tolerable in individuals. These properties make it a valuable natural dietary supplement for research purposes. Sulforaphane has been demonstrated as a potential candidate drug molecule for managing a range of diseases, primarily because of its potent antioxidant, anti-inflammatory, and anti-apoptotic properties, which can be mediated by modulation of ER stress pathways. This review seeks to cover a wealth of data supporting the broad range of protective functions of sulforaphane, improving various diseases, such as cardiovascular, central nervous system, liver, eye, and reproductive diseases, as well as diabetes, cancer, gastroenteritis, and osteoarthritis, through the amelioration of ER stress in both in vivo and in vitro studies.

Ulcerative colitis (UC) is a chronic colonic inflammation with a significant health hazard. Aspergillus awamori (A. awamori) is a microorganism with various bioactive compounds with natural antioxidant and anti-inflammatory properties. The present work aimed to elucidate the protective and therapeutic effects of varying concentrations of A. awamori against acetic acid (AA)-induced ulcerative colitis (UC) in rats. Nine groups of albino male rats were established: a control negative group (G1), a control positive group (G2,AA), and preventive protocol groups (including G3A, G4A, and G5A) that received 100 mg, 50 mg, and 25 mg/kg b.w, respectively, of A. awamori orally and daily from the 1st day of the experiment and for 7 consecutive days. Then, they were subjected to one dose of AA intrarectally on day 8th. G3B, G4B, and G5B were termed as curative protocol groups that received one dose of AA on day 8th and then administered 100 mg, 50 mg, and 25 mg/kg b.w. of A. awamori, respectively, on day 9th and continued receiving these doses daily until day 16th. Rats in the AA group exhibited marked histopathological alterations of the distal colon, with an exaggeration of the DAI. In addition, a remarkable increase in oxidative stress was represented by the elevation of MDA and NO levels with a decline in SOD and GPx activities. In addition, upregulation of TNF-α, IL-6, and IL-1β mRNA expressions and downregulation of Muc2 and Nrf2 levels were detected. Unambiguously, a remarkable anti-inflammatory effect was noticed either in A. awamori prevented or treated groups expounded by reducing and regulating TNF-α, IL-6, and IL-1β with improved pathological lesion scoring. The Muc2, Nrf2, and bcl-2 gene levels were upregulated and restored also. In summary, the findings in this work reveal that A. awamori supplementation successfully alleviated the UC induced by AA, which had a better effect when administered before colitis induction.

A study was conducted to investigate the antibacterial and antioxidative effects of Aloe barbadensis leaf methanolic extract (ABLME) on the quality and spermatozoa fertilising potential of extended goat semen. 100 g of fresh A. barbadensis leaves were washed, chopped, dried, ground and extracted with 95.0% methanol (ABLME). The ABLME was added to egg yolk + sodium citrate (EYSC) diluent at 0.0, 0.5, 1.0, 1.5 and 2.0 g/L and used to extend the goat semen. The extended semen samples were stored at 4oC and were evaluated at 0, 24, 48 and 72 hours post storage. All treatments were replicated thrice in a completely randomized design. Spermatozoa progressive motility (SPM), spermatozoa liveability (SPL), normal spermatozoa (NSP), acrosome integrity (ACI), plasma membrane integrity (PMI), secondary morphological abnormalities (SMA) and microbial load (CFU/mL) were evaluated and analyzed using descriptive statistics and ANOVA at a0.05. Significant reduction in microbial load was observed in samples with 2.0 g/L ABLME (6.83 ± 4.80%) compared to control (27.50 ± 3.20%) at 48 hours. Reduced SMA was recorded for 2.00 g/L ABLME (9.00 ± 0.90%) compared to control (13.67 ± 1.00%). Methanolic extract (2.00 g/L) of A. barbadensis included in egg yolk + sodium citrate diluent gave antibacterial activity to extended buck semen for up to 48 hours. [ABSTRACT FROM AUTHOR]

Objective; Oxidative stress results in neuronal degeneration leading to cognitive decline. Microglia in brain tissue produces reactive oxygen species (ROS), which modulate synaptic communication between neurons. ROS can lead to neuroinflammation, which can cause neurodegeneration and memory loss. Talinum triangulare was investigated for its cognitive, anti-oxidative and anti-inflammatory potentials in male wistar rats. Materials and methods; 25 adult female rats weighing between 150 g–200 g were grouped (n = 5) into Group 1 (control group) received 1 mL/kg of distilled water, group 2–5 were administered with 100 mg/kg, 200 mg/kg and 400 mg/kg T. triangulare methanol extract and 2.5 mg/kg donepezil, 100 mg/kg cadmium respectively via oral gavage.

Introduction: Wound healing is a complex biological process composed of interrelated and overlapping phases: inflammation, migration, proliferation, and maturation. In severe wounds, such as large skin injuries, second or third-degree burns, or diabetes foot ulcers, wound healing is a slow process and rarely leads to the complete restoration of tissue function. Hydrogels are threedimensional polymeric networks that can swell in aqueous environment/biological fluids by absorbing the wound exudates while preventing wound dehydration. Aim: The aim of the study is to explore the development of a photo-crosslinked hydrogel incorporated with two potent natural compounds, curcumin and rutin and its efficacy in promoting wound healing. Materials and methods: Formation of hydrogel incorporated in correct proportions of curcumin and rutin was done. 10% gelatin was added and mixed with ethylene glycol to form gelatin methacrylate. 0.5 % of carrageenan was used. Rutin and curcumin in optimized concentration and 1:1 ratio stock sol. was used. It was then placed in 6 wells for room temp (30 minutes - 1 hour). Potassium chloride (KCl) was added for chemical cross linking, and it was then frozen at 80 degrees C and was lyophilized. Results: The results showed high ability of antimicrobial activity, Antioxidant activity, Compatibility and Anti-inflammatory properties for the photo-crosslinked hydrogel incorporated with curcumin and rutin. Conclusion: It can be concluded from our study that the development of a photo-crosslinked hydrogel incorporated with curcumin and rutin represents a promising approach for enhancing wound healing.

Blocked isocyanate-terminated polyurethane dendrimers of first-generation (G1) to third-generation (G3) build-up with bis-indolyl units were subjected to urethane interchange reaction with 4-hydroxy-2, 2, 6, 6-tetramethylpiperidin-1-yloxyl (4-hydroxy TEMPO). The resulting free radical functionalized dendrimers were thoroughly characterized. The electron paramagnetic resonance (EPR)and vibrating sample magnetometer (VSM) results confirmed that these radical dendrimers are stable and paramagnetic. The cytotoxic effect of G1–G3 TEMPO-dendrimers was studied comprehensively across various cancer cell lines, encompassing human breast cancer (MCF-7 and MDA-MB-231), cervical cancer (SiHa), and lung cancer (A549 and NCI-H460), as well as normal lung epithelial cells (L132). It was observed that these TEMPO-dendrimers exerted cytotoxic effects in all cancer cell lines while demonstrating minimal impact on lung epithelial cells. Notably, MDA-MB-231 displayed heightened susceptibility to the TEMPO-dendrimers. Cell cycle analysis and morphological studies revealed that the TEMPO-dendrimers induced G1 phase cell cycle arrest and cell death specifically in breast cancer cells. Further investigations unveiled that these TEMPO-dendrimers triggered oxidative stress-mediated cell death specifically in breast cancer cells. All these findings suggest that the TEMPO radical dendrimers reported in this work exhibited cytotoxic effects in cancer cells by stimulating oxidative stress. [ABSTRACT FROM AUTHOR]

The free radical scavenging activity of fruits have been analyzed by DPPH, H2O2 and NO assay; it was observed that the ethanolic extract of Rubus niveus fruit is most promising with an IC50 value 16.97 µg/ml. In contrast, aqueous extract scored IC50 value 28.86 µg/ml. The lowest IC50 value was found in aqueous extract of Diospyros kaki i.e., 81.9 µg/ml in DPPH assay. The potential usage of these plants will help the people of these regions to combat nutrient deficiency diseases. Further development of research may help us to come out with powerful functional foods using these fruits. [ABSTRACT FROM AUTHOR]

Geraniol is a common cosmetic and aroma component since, it is a naturally occurring terpenoid in food plants. When used topically, it mainly serves as a pesticide against mites and ticks, as well as mosquitoes. The majority of research indicates that geraniol is safe for both humans and the environment, while when exposed through the skin or the air, some people experience allergies that are not life-threatening. Some aromatic plants' essential oils include geraniol, a commercially significant terpene alcohol. It is a common component in consumer goods made by the flavour and fragrance industries and is considered one among the most essential compounds in these fields. Geraniol is a natural pest control agent with low toxicity, and it has a nice aroma on top of being insecticidal and repellent. One novel family of cancer chemo preventive medicines may be geraniol. Some vascular effects, anti-inflammatory, anti-oxidant, and antibacterial biological activity have also been studied. [ABSTRACT FROM AUTHOR]

Traditional nutraceutical therapy is a promising approach in the management of inflammatory disorders. Fenugreek, bottle gourd, and betel leaf are rich sources of polyphenolic secondary metabolites. They are abundantly found in the Indian subcontinent for the preparation of healthy traditional functional food. Traditional evidence recommended that these herbs could control inflammation. The study was conducted with those herbs to validate their protective role against inflammatory mediators of arthritis and asthma through in‐silico and in‐vitro models. Phytochemical tests revealed the presence of flavonoids, amino acids, polyphenols, and saponins. Molecular docking was performed against six potential inflammatory bio‐marker proteins, like, LOX‐5, 15‐LOX, PLA2, IL‐6, TNFR1 & TNF‐α with the phyto‐marker compounds of test herbs and found satisfactory binding scores against inflammatory bio‐markers. Extended studies with Fenugreek and betel leaf aqueous fractions showcased 87 % and 91 % inhibition of protein denaturation at 200 μg/ml. Bottle‐gourd and betel‐leaf demonstrated 96 % and 98 % inhibition against 15‐Lipoxygenase at 100 μg/ml. TNF‐α and IL‐6 were dropped significantly by 49 % and 36 % upon treatment of betel leaf at 200 μg/ml from the LPS‐stimulated PBMC cultured cells. Findings may recommend the development of commercial anti‐inflammatory polyherbal phytopharmaceuticals for controlling polyarthritis and inflammatory complications subject to preclinical in‐vivo and clinical investigation.

This work was carried out with a view to determining the antioxidant, anti-inflammatory and anti-ulcer properties of the aqueous lyophilized extract of Markhamia lutea. In vitro proteinases inhibition, albumin denaturation, hemolysis of red blood cells by heat, inhibition of the proton pump H+/K+ATPase, FRAP (Ferric reducing antioxidant power) and DPPH (1,1-diphenyl-2-picrylhydrazyl) assays were performed. In vivo, cold water immersion-induced ulceration and methylene blue-induced ulceration was used to determine the anti-ulcer properties of the lyophilizate (100, 200 and 300 mg/kg). In vitro, the lyophilizate (400 μg/mL) significantly inhibited protein denaturation (66.65 %), hemolysis of red blood cells (56.54 %), proteinase activity (69.22 %); then the IC50 was 26.31 μg/mL on proton pump activity. It has also developed a strong ferric reducing antioxidant power (EC50=52.96 mmol FeSO4/g) as well as free radicals scavenging activity (EC50=22.38 μg/mL). In vivo, the aqueous lyophilizate (200 and 300 mg/kg) protected the gastric mucosa (70.68 and 79.00 % protection respectively) and reduced (p<0.05) acetylcholine, calcium and corticosterone concentrations. A decrease in malondialdehyde level, an increased glutathione level and an increased in catalase and SOD activities were recorded. In the methylene blue test, it significantly increased gastric fluid pH, while reducing gastric volume and improving hematological parameters in ulcer animals. In addition, the histological sections show that the aqueous lyophilizate of M. lutea protected the gastric mucosa from the deleterious effects of stress. The aqueous lyophilizate of M. lutea has anti-ulcer properties thanks to its anti-inflammatory, antioxidant and anti-secretory properties. [ABSTRACT FROM AUTHOR]

The antileishmanial activity was more pronounced with the Kombucha tea after 14 days (KBT14) extract (48.86 μg/mL). Conclusion: The Kombucha tea revealed the presence of phenolic compounds at different fermentation time. In addition, a good antioxidant profile was observed with the different radicals analyzed. Also, the inhibition of the Leishmania parasite was obtained. Therefore, the Kombucha tea constitutes a source bioactive molecules with antioxidant properties against Leishmania parasite.

Capsaicin, the main bioactive compound in chili peppers, is widely known for its diverse pharmacological effects, including antioxidant, anti-inflammatory, and anticancer effects. Despite its therapeutic potential, the low yield of natural capsaicin and the challenges in producing it on a large-scale limit broader industrial and clinical applications. This review provides a comprehensive analysis of capsaicin's biosynthesis in plants, chemical and enzymatic synthesis methods, and recent advancements in green production technologies. In addition, innovative applications such as drug delivery systems using nanoencapsulation and micelles are being developed to improve the bioavailability and therapeutic efficacy of capsaicin. Key findings highlight the use of capsaicin in food preservation, packaging, and pharmaceutical formulations. Future research should prioritize the refinement of synthetic routes, innovative delivery technologies, and the development of sustainable industrial processes to fully exploit the therapeutic and commercial potential of capsaicin.

Cardiac arrhythmias remain a significant cause of mortality and morbidity, for novel antiarrhythmic therapies. This study states that the first report of sophoridine (SPN), a quinolizidine alkaloid derived from traditional Chinese herbs, shows promise as a potential candidate due to its anti-arrhythmic and antioxidant properties. The study found that cell viability in H9C2 rat cardiomyocytes remained stable even when treated with SPN at a higher dosage of 100 μg/ml. This phenomenon was accompanied by increases in mitochondria-derived reactive oxygen species (ROS) and calcium/calmodulin-dependent protein kinase II (CaMKII) signaling, at 50 and 100 μg/ml. Glucose fluctuations regulate ventricular arrhythmias caused by SPN by activating the ROS/CaMKII pathway. Experimental models using zebrafish provided additional evidence supporting the regulatory effects of SPN on heart rate. In addition, the administration of SPN resulted in substantial deregulation of crucial genes involved in heart development (nppa, nppb, tnnt2a) at the transcriptional level in zebrafish. These findings provide insight into the various pharmacological properties of SPN and this opens up new possibilities for anti-arrhythmic treatment strategies.

Striae distensae (SD), commonly known as Stretch marks or striae, are one of the most common benign dermal lesions frequently seen in females that often cause a significant physical and psychological impact. A number of treatment modalities ranging from topicals to invasive approaches are commercially available, however, none of the available options is capable of complete eradication of SD. As effectiveness of most of the available topical formulations for SD is attributed to the combined effects of their antioxidant, anti-inflammatory and proliferative effects, allicin and probiotic based topical formulations are hypothesized to be effective in treatment and prevention of SD. Both allicin and probiotics are able to reduce the inflammatory response via suppression of transcription factor i.e., nuclear factor (NF)-κB, and pro-inflammatory cytokines and chemokines levels. Moreover, the antioxidant effect of allicin and probiotics is considered to decrease the reactive oxygen species induced fragmentation of collagen. Also, the effects of allicin on the collagen and elastin tissue as well as beneficial effects of probiotics and their metabolites on skin elasticity and skin hydration are expected to provide multiple target approach for the management of SD. Altogether, a combination formulation containing both allicin and probiotics is considered to be novel approach for the prevention and management of SD.

Sustained release of curcumin from the polymeric carrier system chitosan, a natural biopolymer material derived from chitin originated from natural shrimp shell waste, was studied. Six kinetic models, zero order, first order, Korsmeyer–Peppas (KP), Peppas – Sahlin (PS), Higuchi, and Hixson–Crowell, were applied to study the drug release kinetics. The release mechanism of the drug from the curcumin-chitosan composite was evaluated by changing the pH, ionic strength of the release media, and drug concentration. KP and PS models were selected among the studied models to investigate the drug release mechanism from the chitosan biopolymer based on the R2 values (R2 > 0.99). The model constants m in the PS model and n in the KP model stand for the case II relaxation and Fickian diffusion contribution, respectively. The n being
