Abstract
Dry eye disease (DED) affects a substantial worldwide population with increasing frequency. Current single-targeting DED management is severely hindered by the existence of an oxidative stress-inflammation vicious cycle and complicated intercellular crosstalk within the ocular microenvironment. Here, a nanozyme-based eye drop, namely nanoceria loading cyclosporin A (Cs@P/CeO2), is developed, which possesses long-term antioxidative and anti-inflammatory capacities due to its regenerative antioxidative activity and sustained release of cyclosporin A (CsA). In vitro studies showed that the dual-functional Cs@P/CeO2 not only inhibits cellular reactive oxygen species production, sequentially maintaining mitochondrial integrity, but also downregulates inflammatory processes and repolarizes macrophages. Moreover, using flow cytometric and single-cell sequencing data, the in vivo therapeutic effect of Cs@P/CeO2 was systemically demonstrated, which rebalances the immune-epithelial communication in the corneal microenvironment with less inflammatory macrophage polarization, restrained oxidative stress, and enhanced epithelium regeneration. Collectively, our data proved that the antioxidative and anti-inflammatory Cs@P/CeO2 may provide therapeutic insights into DED management.

The protective effects of naringenin, a citrus flavonoid, non-complexed or complexed with hydroxypropyl-β-cyclodextrin against multiorgan damage caused by neonatal endotoxemia. Int J Biol Macromol 2024; 264:130500. [PMID: 38428770 DOI: 10.1016/j.ijbiomac.2024.130500] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/30/2023] [Revised: 02/16/2024] [Accepted: 02/17/2024] [Indexed: 03/03/2024]
Abstract
BACKGROUND Endotoxemia is a severe and dangerous clinical syndrome that results in elevated morbidity, especially in intensive care units. Neonates are particularly susceptible to endotoxemia due to their immature immune systems. There are few effective treatments for neonatal endotoxemia. One group of compounds with potential in the treatment of neonatal inflammatory diseases such as endotoxemia is the flavonoids, mainly due to their antioxidant and anti-inflammatory properties. Among these, naringenin (NGN) is a citrus flavonoid which has already been reported to have anti-inflammatory, antioxidant, anti-nociceptive and anti-cancer effects. Unfortunately, its clinical application is limited by its low solubility and bioavailability. However, cyclodextrins (CDs) have been widely used to improve the solubility of nonpolar drugs and enhance the bioavailability of these natural products. OBJECTIVE We, therefore, aimed to investigate the effects of NGN non-complexed and complexed with hydroxypropyl-β-cyclodextrin (HPβCD) on neonatal endotoxemia injuries in a rodent model and describe the probable molecular mechanisms involved in NGN activities. METHOD We used exposure to a bacterial lipopolysaccharide (LPS) to induce neonatal endotoxemia in the mice. RESULTS It was found that NGN (100 mg/kg i.p.) exposure during the neonatal period reduced leukocyte migration and decreased pro-inflammatory cytokine (TNF-α, IL-1β and IL-6) levels in the lungs, heart, kidneys or cerebral cortex. In addition, NGN upregulated IL-10 production in the lungs and kidneys of neonate mice. The administration of NGN also enhanced antioxidant enzyme catalase and SOD activity, reduced lipid peroxidation and protein carbonylation and increased the reduced sulfhydryl groups in an organ-dependent manner, attenuating the oxidative damage caused by LPS exposure. NGN decreased ERK1/2, p38MAPK and COX-2 activation in the lungs of neonate mice. Moreover, NGN complexed with HPβCD was able to increase the animal survival rate. CONCLUSION NGN attenuated inflammatory and oxidative damage in the lungs, heart and kidneys caused by neonatal endotoxemia through the MAPK signaling pathways regulation. Our results show that NGN has beneficial effects against neonatal endotoxemia and could be useful in the treatment of neonatal inflammatory injuries.

Abstract
In traditional Chinese medicine, Radix Astragali has played a vital role in treating progressive fibrotic diseases. One of its main active components, astragaloside IV, is a promising anti-fibrotic treatment despite its extremely low bioavailability. Our study aimed to optimize sodium astragalosidate (SA) by salt formation to improve solubility and oral absorption for anti-fibrotic therapy in vivo. Isoproterenol-induced myocardial fibrosis rat models and obese BKS-db mice presenting diabetic kidney fibrosis were used in this study. Daily oral administration of SA (20 mg/kg) for 14 days ameliorated cardiac fibrosis by reducing collagen accumulation and fibrosis-related inflammatory signals, including TNF-α, IL-1β, and IL-6. In db/db mice, SA (5,10, and 20 mg/kg per day for 8 weeks) dose-dependently alleviated lipid metabolism impairment and renal dysfunction when administered orally. Furthermore, Western blot and immunohistochemistry analyses demonstrated that SA treatment inhibited renal fibrosis by suppressing TGF-β1/Smads signaling. Taken together, our findings provide the oral-route medication availability of SA, which thus might offer a novel lead compound in preclinical trial-enabling studies for developing a long-term therapy to treat and prevent fibrosis.

Antioxidants (Basel) 2023; 12:antiox12040877.

Abstract
Mitochondrial dysfunction triggered by increased reactive oxygen species (ROS) generation is involved in the pathogenesis and development of cardiac hypertrophy. Nanoceria (cerium oxide nanoparticle) has powerful ROS-scavenging properties and is considered a potential therapeutic option for curbing ROS-related disorders. Here, we explored the signaling mechanism underlying the protective effects of nanoceria against angiotensin (Ang) II-stimulated pathological response in H9c2 cardiomyoblasts. Our data revealed that pretreatment of H9c2 cardiomyoblasts with nanoceria significantly prevented Ang II-stimulated generation of intracellular ROS, aberrant expression of pro-inflammatory cytokines, and hypertrophy markers. Nanoceria pretreatment increased the mRNA levels of genes regulating the cellular antioxidant defense system (SOD2, MnSOD, CAT) in Ang II-treated cells. Furthermore, nanoceria restored mitochondrial function by decreasing mitochondrial ROS, increasing mitochondrial membrane potential (MMP), and promoting the mRNA expression of genes associated with mitochondrial biogenesis (PGC-1α, TFAM, NRF1, and SIRT3) and mitochondrial fusion (MFN2, OPA1). Collectively, these findings demonstrate the protective effects of nanoceria against Ang II-mediated mitochondrial dysfunction and pathological hypertrophy in H9c2 cells.

Abstract
Renal fibrosis is a hallmark feature of chronic kidney diseases (CKDs). However, despite the increased prevalence of renal fibrosis, there is no approved antifibrotic drug for the management of renal fibrosis. Cerium oxide nanoparticles (CONPs) have been demonstrated to possess a number of properties including antioxidant, anti-inflammatory and nephroprotective activity. As the kidneys are rich in lactoferrin (Lf) receptors, we synthesised the lactoferrin-CONP (Lf-CONP) system to be used for active targeting of the kidneys and provide antifibrotic effects of CONPs to the kidneys. We used the unilateral ureteral obstruction (UUO)-induced renal fibrosis model and treated the animals with Lf-CONP to observe the antifibrotic effects of Lf-CONP. Lf-CONP was found to inhibit the progression of renal fibrosis in a superior manner when compared to CONPs alone.

Abstract
Liver fibrosis is one of the major liver complications which eventually progresses to liver cirrhosis and liver failure. Cerium oxide nanoparticles, also known as nanoceria (NC) are nanoparticles with potential antioxidant and anti-inflammatory activities. Herein, we evaluated the hepatoprotective and anti-fibrotic effects of nanoceria (NC) against bile duct ligation (BDL) induced liver injury. NC were administered i.p. for 12 days (0.5 and 2 mg/kg) to C57BL/6J mice. The biochemical markers of liver injury, oxidative and nitrosative stress markers, inflammatory cytokines were evaluated. Fibrosis assessment and mechanistic studies were conducted to assess the hepatoprotective effects of NC. Administration of NC proved to significantly ameliorate liver injury as evident by reduction in SGOT, SGPT, ALP and bilirubin levels in the treated animals. NC treatment significantly reduced the hydroxyproline levels and expression of fibrotic markers. In summary, our findings establish the hepatoprotective and anti-fibrotic effects of NC against BDL induced liver injury and liver fibrosis. These protective effects were majorly ascribed to their potential ROS inhibition and antioxidant activities through catalase, superoxide dismutase (SOD)-mimetic properties and auto-regenerating capabilities.

Abstract
Copper-induced cardiac injury is not widely reported in spite of its ability to cause oxidative damage and tissue injury. Structural and morphological changes in the cardiac tissue are triggered via oxidative stress and inflammatory responses following copper exposure. The varied and unavoidable exposure of copper through contaminated food and water warrants a safe and effective agent against its harmful effects. Since the heart is highly sensitive to changes in the redox balance, the present study was undertaken to examine the protective effects of melatonin against copper-induced cardiac injury. Sprague Dawley (SD) rats were exposed to 100 ppm of elemental copper via drinking water for 4 months. The cardiac tissue was evaluated for various biochemical, histological, and protein expression studies. Animals exposed to copper exhibited induced oxidative stress and cardiac injury compared to normal control. To this end, we found that melatonin treatment ameliorated copper-induced alterations in tissue oxidative variables like ROS, nitrate, MDA, and GSH. In addition, histological examinations unravelled decreased cardiac muscle dilation, atrophy, and cardiomyopathy in melatonin-treated rats. Furthermore, melatonin-treated rats were associated with reduced tissue copper levels, collagen deposition, α-SMA, and increased HO-1 expression as compared to rats exposed exclusively to copper. Moreover, the levels of NF-κB and cardiac markers such as CK-MB, cTnI, and cTnT were found to be decreased in the melatonin-treated animals. Altogether, melatonin-triggered increase in antioxidant capacity resulting in reduced aggregation of ECM components demonstrates the therapeutic potential of melatonin in the treatment of cardiac injury and tissue fibrosis.

Abstract
Hinokitiol is a natural bio-active tropolone derivative with promising antioxidant and anti-inflammatory properties. This study was conducted to evaluate the ameliorative effects of hinokitiol against acute pancreatitis induced by cerulein. Mice were pre-treated with hinokitiol intraperitoneally for 7 days (50 and 100 mg/kg), and on the final day of study, cerulein (6 × 50 μg/kg) was injected every hour for six times. Six hours after the last dose of cerulein, blood was collected from the mice through retro-orbital plexus for biochemical analysis. After blood collection, mice were euthanized and the pancreas was harvested for studying effects on oxidative stress, pro-inflammatory cytokines, immunohistochemistry and histopathology of tissue sections. Hinokitiol treatment significantly reduced edema of the pancreas and reduced the plasma levels of lipase and amylase in mice with cerulein-induced acute pancreatitis. It also attenuated the oxidative and nitrosative stress related damage as evident from the reduced malondialdehyde (MDA) and nitrite levels, which were significantly increased in the mice with acute pancreatitis. Furthermore, hinokitiol administration significantly reduced the pancreatitis-evoked decrease in the activity of catalase, glutathione (GSH) and superoxide dismutase (SOD) in the pancreatic tissue. Pre-treatment with hinokitiol significantly reduced the elevated levels of pro-inflammatory cytokines like interleukin-6 (IL-6), interleukin-1β (IL-1β), tumor necrosis factor-alpha (TNF-α) as well as increased the levels of anti-inflammatory cytokine interleukin-10 (IL-10) in the pancreatic tissue of mice with acute pancreatitis. The immunohistochemical expression of nuclear factor kappa light chain enhancer of activated B cells (NF-κB), cyclooxygenase (COX-2) and TNF-α were significantly decreased by hinokitiol in mice with cerulein-induced acute pancreatitis. In conclusion, the results of the present study demonstrate that hinokitiol has significant potential to prevent cerulein-induced acute pancreatitis.

Abstract
Silymarin (Sil) was conjugated to selenium nanoparticles (SeNPs) to increase Sil bioavailability. The conjugates were monodisperse; the average diameter of the native SeNPs was ~ 20-50 ± 1.5 nm, whereas that of the conjugates was 30-50 ± 0.5 nm. The use of SeNPs to increase the bioavailability of Sil was examined with the MH-22a, EPNT-5, HeLa, Hep-2, and SPEV-2 cell lines. The EPNT-5 (glioblastoma) cells were the most sensitive to the conjugates compared to the conjugate-free control. The conjugates increased the activity of cellular dehydrogenases and promoted the penetration of Sil into the intracellular space. Possibly, SeNPs play the main part in Sil penetration of cells and Sil penetration is not associated with phagocytosis. Thus, SeNPs are promising for use as a Sil carrier and as protective antigens.

Rocha LSR, Simões AZ, Macchi C, Somoza A, Giulietti G, Ponce MA, Longo E. Synthesis and defect characterization of hybrid ceria nanostructures as a possible novel therapeutic material towards COVID-19 mitigation. Sci Rep 2022; 12:3341. [PMID: 35228568 PMCID: PMC8885868 DOI: 10.1038/s41598-022-07200-9] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2021] [Accepted: 02/14/2022] [Indexed: 02/06/2023] Open
Abstract
This study reports the synthesis of hybrid nanostructures composed of cerium dioxide and microcrystalline cellulose prepared by the microwave-assisted hydrothermal route under distinct temperature and pH values. Their structural, morphological and spectroscopic behaviors were investigated by X-Rays Diffraction, Field Emission Gun Scanning Electron Microscopy, High-Resolution Transmission Electron Microscopy, and Fourier-Transform Infrared, Ultraviolet-Visible, Raman and Positron Annihilation Lifetime spectroscopies to evaluate the presence of structural defects and their correlation with the underlying mechanism regarding the biocide activity of the studied material. The samples showed mean crystallite sizes around 10 nm, characterizing the formation of quantum dots unevenly distributed along the cellulose surface with a certain agglomeration degree. The samples presented the characteristic Ce-O vibration close to 450 cm-1 and a second-order mode around 1050 cm-1, which is indicative of distribution of localized energetic levels originated from defective species, essential in the scavenging of reactive oxygen species. Positron spectroscopic studies showed first and second lifetime components ranging between 202-223 ps and 360-373 ps, respectively, revealing the presence of two distinct defective oxygen species, in addition to an increment in the concentration of Ce3+-oxygen vacancy associates as a function of temperature. Therefore, we have successfully synthesized hybrid nanoceria structures with potential multifunctional therapeutic properties to be further evaluated against the COVID-19.

Lung function improves after delayed treatment with CNP-miR146a following acute lung injury. NANOMEDICINE: NANOTECHNOLOGY, BIOLOGY AND MEDICINE 2022; 40:102498. [PMID: 34838994 PMCID: PMC8616767 DOI: 10.1016/j.nano.2021.102498] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/16/2021] [Revised: 10/09/2021] [Accepted: 11/10/2021] [Indexed: 11/20/2022]
Abstract
Acute respiratory distress syndrome (ARDS) is a highly morbid pulmonary disease characterized by hypoxic respiratory failure. Its pathogenesis is characterized by unrestrained oxidative stress and inflammation, with long-term sequelae of pulmonary fibrosis and diminished lung function. Unfortunately, prior therapeutic ARDS trials have failed and therapy is limited to supportive measures. Free radical scavenging cerium oxide nanoparticles (CNP) conjugated to the anti-inflammatory microRNA-146a (miR146a), termed CNP-miR146a, have been shown to prevent acute lung injury in a pre-clinical model. In this study, we evaluated the potential of delayed treatment with CNP-miR146a at three or seven days after injury to rescue the lung from acute injury. We found that intratracheal CNP-miR146a administered three days after injury lowers pulmonary leukocyte infiltration, reduce inflammation and oxidative stress, lower pro-fibrotic gene expression and collagen deposition in the lung, and ultimately improve pulmonary function.

Abstract
Nanotechnology has been a boon for the biomedical field due to the freedom it provides for tailoring of pharmacokinetic properties of different drug molecules. Nanomedicine is the medical application of nanotechnology for the diagnosis, treatment and/or management of the diseases. Cerium oxide nanoparticles (CNPs) are metal oxide-based nanoparticles (NPs) which possess outstanding reactive oxygen species (ROS) scavenging activities primarily due to the availability of "oxidation switch" on their surface. These NP have been found to protect from a number of disorders with a background of oxidative stress such as cancer, diabetes etc. In fact, the CNPs have been found to possess the environment-dependent ROS modulating properties. In addition, the inherent catalase, SOD, oxidase, peroxidase and phosphatase mimetic properties of CNPs provide them superiority over a number of NPs. Further, chemical reactivity of CNPs seems to be a function of their surface chemistry which can be precisely tuned by defect engineering. However, the contradictory reports make it necessary to critically evaluate the potential of CNPs, in the light of available literature. The review is aimed at probing the feasibility of CNPs to push towards the clinical studies. Further, we have also covered and censoriously discussed the suspected negative impacts of CNPs before making our way to a consensus. This review aims to be a comprehensive, authoritative, critical, and accessible review of general interest to the scientific community.

Abstract
Acute respiratory distress syndrome (ARDS) is a devastating pulmonary disease with significant in-hospital mortality and is the leading cause of death in COVID-19 patients. Excessive leukocyte recruitment, unregulated inflammation, and resultant fibrosis contribute to poor ARDS outcomes. Nanoparticle technology with cerium oxide nanoparticles (CNP) offers a mechanism by which unstable therapeutics such as the anti-inflammatory microRNA-146a can be locally delivered to the injured lung without systemic uptake. In this study, we evaluated the potential of the radical scavenging CNP conjugated to microRNA-146a (termed CNP-miR146a) in preventing acute lung injury (ALI) following exposure to bleomycin. We have found that intratracheal delivery of CNP-miR146a increases pulmonary levels of miR146a without systemic increases, and prevents ALI by altering leukocyte recruitment, reducing inflammation and oxidative stress, and decreasing collagen deposition, ultimately improving pulmonary biomechanics.

A direct thrombin inhibitor, dabigatran etexilate protects from renal fibrosis by inhibiting protease activated receptor-1. Eur J Pharmacol 2020; 893:173838.

Abstract
Chronic kidney disease (CKD) involves interstitial fibrosis as an influential underlying pathological process associated with compromised renal function regardless of etiological cause of the injury. The tubulointerstitial fibrosis is found to be well correlated with declining renal function and its subsequent culmination into renal failure. Given the prominent role of thrombin in multiple diseases, it was tempting for us to investigate the outcome of a direct thrombin inhibitor in renal injury. We investigated the involvement of thrombin in renal injury and fibrosis by using an FDA approved orally active, direct thrombin inhibitor, dabigatran etexilate (DB). We used a robust experimental model of unilateral ureteral obstruction (UUO)-induced renal injury which shows progressive tubulointerstitial fibrosis (TIF) along with tubular injury and inflammation. The obstructed kidney showed severe TIF as compared to control kidneys. The administration of DB significantly inhibited UUO-induced collagen-1 and TIF by inhibition of thrombin activated protease activated receptor (PAR)-1 expression in fibrotic kidney. In addition, DB administration improved histoarchitecture of obstructed kidney, inhibited TGF-β and SNAI2-induced epithelial-mesenchymal transition (EMT) program. Our study highlights the importance of thrombin signalling in TIF and provides strong evidences to support the notion that a direct thrombin inhibitor ameliorates TIF by PAR-1 mediated mechanism.

Abstract
The COVID-19 pandemic has emerged as an unprecedented global healthcare emergency and has devastated the global economy. The SARS-CoV-2 virus replicates in the host cells and is seemingly much more virulent compared to other flu viruses, as well as the SARS-CoV-1. The respiratory complications of the disease include acute respiratory distress syndrome (ARDS), cytokine storm, systemic inflammation, and pulmonary fibrosis. Nanoceria (NC) is a versatile rare earth nanoparticle with remarkable catalase and superoxide dismutase mimetic redox regenerative properties. Interestingly, NC possesses promising anti-inflammatory, antioxidant and anti-fibrotic properties, making it an attractive tool to fight against the SARS-CoV-2 as well as the associated systemic complications. Until now, there is no clinically approved vaccine or drug for the treatment of COVID-19, and the conquest to find a novel therapy for this global havoc is being undertaken at a warlike pace. Herein, based on preclinical evidence, we hypothesize that NC owing to its unique pharmacological properties, might be an attractive preclinical candidate to win the battle over COVID-19. Further, it may be used as a prevention or treatment strategy in combination with other drugs.

Abstract
Aim: To investigate the effect of cerium oxide nanoparticles (nanoceria) on psoriasis. Materials & methods: Fourier transform infrared, powder x-ray diffraction and scanning electron microscopy were used to characterize nanoceria. Imiquimod (62.5 mg/mice) was used for the induction of psoriasis while nanoceria was administered/applied via multiple routes (topical gel, intraperitoneal and subcutaneous) as a therapeutic intervention once daily. Results: Nanoceria significantly attenuated splenic hypertrophy, psoriasis area severity index scoring, and lipid peroxidation. It also reduced the expression of various inflammatory and proliferation markers such as IL-17, IL-22, IL-23, Ki-67, NF-κB, COX-2 and GSK3. Conclusion: Nanoceria exerts an antipsoriatic effect by inhibiting major pathogenic immune axes namely the Th-cell mediated IL-17/IL-23 axis and by downregulating other crucial inflammatory proteins like NF-κB, COX-2 and GSK3.

Abstract
Arsenic trioxide (ATO) is commonly used to treat patients with acute promyelocytic leukemia since it was authorized by the U.S. Food and Drug Administration in the 1970s, but its applicability has been limited by its cardiotoxic effects. Therefore, the aim of the present study was to investigate the cardioprotective effects and underlying mechanism of crocetin (CRT), the critical ingredient of saffron. Sprague-Dawley rats were then randomly divided into four groups (n=10/group): i) Control group; ii) ATO group, iii) CRT-low (20 mg/kg) group; and iv) CRT-high (40 mg/kg) group. Rats in the Control and ATO groups were intraperitoneally injected with equal volumes of 0.9% sodium chloride solution, and CRT groups were administered with either 20 and 40 mg/kg CRT. Following 6 h, all groups except the Control group were intraperitoneally injected with 5 mg/kg ATO over 10 days. Cardiotoxicity was indicated by changes in electrocardiographic (ECG) patterns, morphology and marker enzymes. Histomorphological changes in the heart tissue were observed by pathological staining. The levels of superoxide dismutase, glutathione peroxidase, malondialdehyde and catalase in the serum were analyzed using colometric commercial assay kits, and the levels of reactive oxygen species in the heart tissue were detected using the fluorescent probe dihydroethidium. The expression levels of inflammatory factors and activities of apoptosis-related proteins were analyzed using immunohistochemistry. The protein expression levels of silent information regulator of transcription 1 were measured using western blotting. Cardiotoxicity was induced in male Sprague-Dawley rats with ATO (5 mg/kg). CRT (20 and 40 mg/kg) and ATO were co-administered to evaluate possible cardioprotective effects. CRT significantly reduced the heart rate and J-point elevation induced by ATO in rats. Histological changes were evaluated via hematoxylin and eosin staining. CRT decreased the levels of creatine kinase and lactate dehydrogenase, increased the activities of superoxide dismutase, glutathione-peroxidase and catalase, and decreased the levels of malondialdehyde and reactive oxygen species. Moreover, CRT downregulated the expression levels of the pro-inflammatory factors IL-1, TNF-α, IL-6, Bax and p65, as well as increased the expression of Bcl-2. It was also identified that CRT enhanced silent information regulator of transcription 1 protein expression. Thus, the present study demonstrated that CRT treatment effectively ameliorated ATO-induced cardiotoxicity. The protective effects of CRT can be attributed to the inhibition of oxidative stress, inflammation and apoptosis. Therefore, CRT represents a promising therapeutic method for improving the cardiotoxic side effects caused by ATO treatment, and additional clinical applications are possible, but warrant further investigation.

Abstract
Several biocompatible materials have been applied for managing soft tissue lesions; cerium oxide nanoparticles (CNPs, or nanoceria) are among the most promising candidates due to their outstanding properties, including antioxidant, anti-inflammatory, antibacterial, and angiogenic activities. Much attention should be paid to the physical properties of nanoceria, since most of its biological characteristics are directly determined by some of these relevant parameters, including the particle size and shape. Nanoceria, either in bare or functionalized forms, showed the excellent capability of accelerating the healing process of both acute and chronic wounds. The skin, heart, nervous system, and ophthalmic tissues are the main targets of nanoceria-based therapies, and the other soft tissues may also be evaluated in upcoming experimental studies. For the repair and regeneration of soft tissue damage and defects, nanoceria-incorporated film, hydrogel, and nanofibrous scaffolds have been proven to be highly suitable replacements with satisfactory outcomes. Still, some concerns have remained regarding the long-term effects of nanoceria administration for human tissues and organs, such as its clearance from the vital organs. Moreover, looking at the future, it seems necessary to design and develop three-dimensional (3D) printed scaffolds containing nanoceria for possible use in the concepts of personalized medicine.

Abstract
Chronic kidney disease (CKD) has wide prevalence globally that affects a considerable population and has renal fibrosis (RF) as a hallmark feature. RF is characterized by abnormal deposition of extracellular matrix (ECM) in the interstitial space of renal tissue. There are only few studies where nanoparticles (NPs) were used for targeting the kidney mainly due to their size-dependent constraints. Further, most of the studies have been carried out in healthy animals. As the diseased kidney becomes susceptible to accumulation of nanoparticles, we hypothesized that nanoparticles (size ∼10 nm) could reach the kidney and might provide protective effects due to their inherent properties. We investigated the protective effects of cerium oxide nanoparticles (CONPs) with promising antioxidant activity in a CKD model. We, to the best of our knowledge, are first to report that CONPs abrogated RF by inhibiting transforming growth factor-β (TGF-β) signaling and epithelial-mesenchymal transition (EMT) in a fibrotic kidney.

Abstract
Herein, we studied the effect of Withaferin A (WFA) in reversing bile duct ligation (BDL)-induced liver fibrosis. BDL was performed on C57BL/6J mice and 2 days later, WFA (1 and 3 mg/kg) was administered for 12 days. Estimation of liver enzymes and assays for lipid peroxidation, reduced glutathione, and nitrite levels were performed. Picrosirius red, Masson's trichrome, and H&E staining were performed to study histological changes. WFA proved to be a holistic intervention for the attenuation and reversal of liver fibrosis. Reduction in inflammatory stimulus and oxidative stress restored the levels of stress-related chaperone Hsp70 (p < .001 vs. BDL) in WFA treated groups. We found 3.59-fold (p < .001) and 1.37-fold (p < .01) reduction in the expression of lysyl oxidase like2 (LOXL2) and Snail1, respectively, in WFA-treated animals as compared with BDL animals. These reductions led to 1.9-fold (p < .001) elevation in levels of E-cadherin signifying the reversal of epithelial to mesenchymal transition by WFA. Further, the reduction in LOXL2 levels enhanced the susceptibility of fibrotic scar toward degradation. The picrosirius red and Masson's trichrome staining done on liver tissue sections supported the above results. We, for the first time, report the role of WFA in modulating the expression of LOXL2 and Snail1 in addition to vimentin inhibition and regulation of NFκB signaling for the treatment of liver fibrosis.

Abstract
Aim Aiming to produce pyridine azo disperse dyes with good fastness properties and promising antimicrobial activity, a number of novel systems of polyfunctionalized pyridine azo dyes and their selenium nanoparticles (SeNPs) were synthesized. Materials and methods The synthesized products were formed by the reaction of diazotized aniline derivatives or diazotized amino antipyrene with any of dibenzoyl methane or benzoyl acetone and cyanoacetamide in boiling ethanolic sodium ethoxide. The structures of the newly synthesized compounds were elucidated by elemental analysis and spectral data. Moreover, (SeNPs) of the pyridine azo disperse dyes were characterized by Ultra-Violet -Visible spectrophotometry, dynamic light scattering , X-ray diffraction, and transmission electron microscope analysis. On the other hand, the synthesized dyes and its (SeNPs) were applied for disperse dyeing of nylon 66 and their fastness properties were measured, such as washing, rubbing, perspiration, and light fastness. In addition, the antimicrobial activities for all the synthesized compounds and for (SeNPs) prepared compounds (2bN, 2cN, 2fN, 2gN, 2hN) were evaluated. Results Compounds 2bN, 2c, 2cN, 2fN, 2gN, 2h, 2hN, and 2i were the most active compounds against all Gram-positive and Gram-negative bacterial species. While, compounds 2b, 2f, 2g, and 5b were the most active toward some of the bacterial strains (at least two from the selected four strains). Moreover, compounds 2bN, 2cN, 2fN, 2gN, 2h, 2hN showed higher activity toward the fungal strain. Also, the minimal inhibitory concentrations for all the most active compounds were determined. Conclusion Finally, all the (SeNPs) compounds revealed higher activity against bacterial and fungal strains than the other synthesized compounds.

Abstract
Chronic kidney disease (CKD) is one of the major global health concerns and is responsible for end-stage renal disease (ESRD) complications. Inflammation plays a pivotal role in the progression of CKD. In the present study, we evaluated the renoprotective effects of a potent immunomodulator steroidal lactone, Withaferin A (WfA), in an animal model of renal injury (unilateral ureteral obstruction, UUO) and further investigated if the inhibition of inflammatory signaling can be a useful approach to reduce renal injury. Animals were randomly divided into five groups: Sham control, UUO control, WfA control, WfA low dose (1 mg/kg), and WfA high dose (3 mg/kg). Oxidative stress was measured by the estimation of reduced glutathione and lipid peroxidation levels. H&E and Picrosirius Red staining were performed to assess the extent of histological damage and collagen deposition. Furthermore, the molecular mechanism of the WfA effects was explored by immunohistochemistry, enzyme-linked immunosorbent assay, multiplex analysis of transforming growth factor β (TGF-β) pathway, and an array of inflammatory cytokines/chemokines. Interestingly, our pharmacological intervention significantly attenuated tissue collagen, inflammatory signaling, and macrophage signaling. WfA intervention abrogated the inflammatory signaling as evident from the modulated levels of chemokines and cytokines. The levels of TGF-β along with downstream signaling molecules were also attenuated by WfA treatment as revealed by inhibition in the expression of TGF-β1, TGF-β2, p-Smad2, p-Smad3, total Smad4, p-Akt, and p-ERK. We, to the best of our knowledge, prove for the first time that WfA has potential renoprotective activity against UUO-induced nephropathy due to its outstanding anti-inflammatory properties.

Abstract
Crocin is isolated from saffron and has multiple activities. There are many reports on its beneficial effects for cardiovascular disease, but crocin's effects on anti-myocardial fibrosis have not yet been reported. This study investigated crocin's effects and potential mechanisms on isoproterenol (ISO)-induced myocardial fibrosis (MF) in mice. Mice were infused intraperitoneally with crocin with concurrent ISO subcutaneous injections over 2 weeks. Electrocardiography, cardiac weight index (CWI), hydroxyproline content, and heart morphology changes were observed. Administration of crocin markedly decreased heart rate, J-point elevation, QRS interval, CWI, and hydroxyproline content in the myocardial tissues, and improved heart pathologic morphology. Versus the control group, the ISO group showed an increase in lactate dehydrogenase and creatine kinase activities and malondialdehyde content. Meanwhile, superoxide dismutase, catalase, and glutathione contents decreased in the ISO group; crocin caused a significant reduction in oxidative stress levels in ISO-induced MF. ISO led to a significant increase in interleukin-1 and -6 and tumor necrosis factor-α in addition to nuclear factor kappa B (NF-κB) (p65) and toll-like receptor (TLR) 4 expressions. Crocin treatment suppressed these inflammatory cytokine expressions. Moreover, crocin treatment caused a significant decrease in connective tissue growth factor and transforming growth factor-β1 mRNA levels in addition to a decrease in B cell lymphoma-2, Bcl-2-associated X protein, caspase-3, and cleaved caspase-3 expressions. Crocin has a protective effect on ISO-induced MF, which may be associated with the TLR4/NF-κB (p65) signal transduction pathway.

Abstract
Aim: The present study was carried out to assess the effect of nanoceria (NC) on pancreatic inflammation caused by cerulein. Methods: NC was characterized and in vitro studies were carried out in murine macrophages. The in vivo effects were tested on cerulein-induced pancreatitis. Results: In vitro treatment with NC remarkably protected macrophages from lipopolysaccharide-induced inflammation and oxidative stress as evident from the results of 2',7'-dichlorofluorescin diacetate, JC-1 and MitoSox staining. In vivo treatment with NC showed potent superoxide dismutase and catalase mimetic activity, antipancreatitis activity and improved histology. Furthermore, it reduced the expression of p65-NF-κB and acetylation of histone H3 at lysine K14, K56 and K79 residues. Conclusion: We for the first time, demonstrate that NC may be a promising candidate for the therapy of pancreatitis.

Abstract
Chronic kidney disease (CKD) involves interstitial fibrosis as an underlying pathological process associated with compromised renal function irrespective of etiological cause of the injury. The transforming growth factor-β (TGF-β) plays a pivotal role in progression of renal fibrosis. TGF-β transduces its downstream signalling by phosphorylation of smad2/3 and also regulates epithelial-mesenchymal-transition (EMT), a program centrally involved in activation of fibroblasts. Renal fibrosis was induced in Swiss albino mice by unilateral ureteral obstruction of animals. Kidney tissues were evaluated for fibrotic protein expression by western blot and immunohistochemistry. The administration of nimbolide (NB) to UUO animals reduced the oxidative stress, expression of ECM proteins, TGF-β, p-smad and EMT program. Further, NB administration also improved histoarchitecture of obstructed kidney and reduced the collagen deposition in kidney. Our results provided compelling evidence to support antifibrotic activity of NB by reduction in oxidative stress, TGF-β, and EMT program in fibrotic kidney. The administration of NB in animals blunted the UUO-induced renal injury, inflammation and reduced fibrogenesis in obstructed kidney.

Abstract
Cisplatin (CP) is one of the most important anticancer compounds with its therapeutic usefulness in diverse types of solid cancer. However, its use is limited due to nephrotoxicity induced by it. Oxidative stress is an effective participant which contributes actively to pathogenesis of CP-induced nephrotoxicity. Nanoparticle form of a rare earth metal cerium, also known as nanoceria (NC), has come up as a potential antioxidant and anti-inflammatory agent. In the present study, administration of CP in Swiss mice resulted in reduction of body weight, increased oxidative stress and pro-inflammatory cytokine levels including IL-6 and TNF-α along with alteration in normal histological architecture of kidney. On the contrary, NC (0.2 and 2 mg/kg i.p.) ameliorated nephrotoxicity of CP which was evident by reduction in levels of renal injury markers in plasma, i.e., creatinine and blood urea nitrogen. NC ameliorated oxidative stress by showing a reduction in levels of malondialdehyde and increased levels of endogenous antioxidants reduced glutathione and catalase. Further, NC treatment also reduced the levels of pro-inflammatory cytokines. Furthermore, protective effect of NC was also corroborated by histopathological studies wherein, kidneys from CP group showed altered tissue structure after acute as well as chronic exposure of CP while the tissues from treated groups showed absence of alterations in kidney histology. The results from present study suggested that oxidative stress and pro-inflammatory cytokines play a central role in pathogenesis of CP-induced nephrotoxicity and NC provides protection from CP-induced nephrotoxicity due to its antioxidant and anti-inflammatory properties.

Abstract
This study was performed to study the in vitro and in vivo efficacy of hydroalcoholic extract of curry leaf (CLE) rich in carbazole alkaloids, against LPS-induced inflammation in Raw 264.7 macrophages and cerulein-induced acute pancreatitis, respectively. CLE was characterized by Fourier-transform infrared (FTIR) and liquid chromatography-mass spectrometry. Raw 264.7 cells were stimulated with LPS (2 μg/ml) and treated with CLE. The animals were treated with two doses of CLE (100 and 300 mg/kg). Plasma biochemistry, tissue lipid peroxidation, cytokines, and histological examination were evaluated. CLE was found to decently scavenge the activity of DPPH radical. It dose dependently suppressed nitrite production and oxidative stress in macrophages. CLE alleviated LPS-induced inflammation in macrophages as evident from the results of various inflammatory cytokines (IL-1β, IL-6, and TNF-α). In vivo, CLE reduced cerulein-induced pancreatic edema. CLE significantly abrogated the cerulein-induced lipid peroxidation, nitrite, MPO, and GSH levels. The inflammatory cytokines and p65-NFκB activity were significantly reduced by CLE. Mechanistically, CLE reduced the expression of NT, MPO, IL-1β, ICAM-1, and COX-2, and increased the expression of Nrf2. It reduced distant organ damage markers as well. We report for the first time that CLE holds substantial potential for the prevention of acute pancreatitis.

Abstract
Oxidative stress plays a major role in acute pancreatitis (AP), leading to massive macrophage infiltration. Nanoyttria (NY) possesses potent free radical scavenging activity. As reactive oxygen species and inflammation play major role in AP, we hypothesized that NY may alleviate cerulein induced AP. NY ameliorated LPS induced oxidative stress in vitro. It reduced ROS, superoxide radical generation and restored the mitochondrial membrane potential in macrophages. Interestingly, NY reduced plasma amylase and lipase levels and attenuated the mitochondrial stress and inflammatory markers. NY suppressed the recruitment of inflammatory cells around the damaged pancreatic acinar cells. Furthermore, NY intervention perturbed the course of AP via reduction of endoplasmic reticulum (ER) stress markers (BiP, IRE1 and Ero1-Lα), and molecular chaperones (Hsp27 and Hsp70). We, to the best of our knowledge, report for first time that NY can attenuate experimental AP by restoration of mitochondrial and ER homeostasis through Nrf2/NFκB pathway modulation.

Abstract
Acute pancreatitis (AP) is an exocrine dysfunction of the pancreas where oxidative stress and inflammatory cytokines play a key role in induction and progression of the disease. Studies have demonstrated that antioxidant phytochemicals have been effective in improving pancreatitis condition, but there are no clinically approved drugs till date. Our study aims to assess the preventive activity of visnagin, a novel phytochemical isolated from Ammi visnaga against cerulein induced AP. Male Swiss albino mice were divided into six groups (n = 6, each group) comprising of normal control, cerulein control, seven day pre-treatment with visnagin at three dose levels; visnagin low dose (10 mg/kg), visnagin mid dose (30 mg/kg), visnagin high dose (60 mg/kg) and visnagin control (60 mg/kg). AP was induced by six injections of cerulein (50 μg/kg, i.p.) on the 7th day and the animals were sacrificed after 6 h of last cerulein dose. Various markers of pancreatic function, oxidative stress and inflammation were assessed. Visnagin was found to be effective in reducing plasma amylase and lipase levels, reduced cerulein induced oxidative stress. Visnagin dose dependently decreased the expression of IL-1β, IL-6, TNF-α and IL-17. It attenuated the levels of nuclear p65-NFκB. Visnagin improved the antioxidant defence by improving Nrf2 expression and halted pancreatic inflammation by suppressing NFκB and nitrotyrosine expression in the acinar cells. Further, it attenuated the expression of markers of multiple organ dysfunction syndrome and reduced inflammatory cytokines in lungs and intestine. Cumulatively, these findings indicate that visnagin has substantial potential to prevent cerulein induced AP.

Abstract
There is a need for short-term, reliable and reproducible animal model of chronic pancreatitis (CP) in small animals like mice. This study was aimed to establish the 9 exposures of cerulein-induced CP in mice. Repeated intraperitoneal cerulein injections were performed at 6 consecutive doses (50 μg/kg)/day, 3 days a week for 3 weeks to induce chronic pancreatitis in Swiss albino mice. The severity of damage was assessed by biochemical assays and histopathology. The expression of pro-inflammatory cytokine and fibrotic proteins was assessed by IHC and western blotting. The cerulein treated mice showed significantly elevated plasma amylase (p < .0285) and lipase levels (p < .0022) and resulted in significantly increased pancreatic oxidative (p < .0022) and nitrosative (p < .0022) stress. The hydroxyproline levels were 3.06 fold increased in the cerulein treated mice. The expressions of fibrotic cytokine TGF-β1 by 1.8 folds and pro-inflammatory cytokines TNF-α by 2.3 fold, IL-6 by 2.2 fold and IL-1β by 3.7 fold were markedly increased in cerulein treated mice. The histological evaluations indicated increased inflammatory cells infiltration and deposition of collagen. Moreover, the expression of fibrotic markers such as α-SMA increased by 2.5 folds (p < .00014), collagen1a by 1.3 folds (p < .0258) and fibronectin by 3.5 folds (p < .00014) were significantly increased. Our study demonstrates the superiority of 9 exposures of cerulein-induced CP model in mice with the reduction of duration, cerulein exposure, more economical and mortality rate of mice over the available models. Therefore, our model may be suitable to evaluate the pharmacological effects of new drugs in chronic pancreatitis.

Abstract
Aim: The present study was designed to probe the cardioprotective effects of nanoyttria (NY). Materials & methods: NY was characterized using various techniques. Isoproterenol (ISO)-induced cardiotoxicity challenged mice were treated with NY for 28 days at two doses (0.4 and 4 mg/kg, intraperitoneally). Results: NY demonstrated free radical scavenging activity as shown by a 2,2-diphenyl-1-picrylhydrazyl assay. NY treatment showed alleviation of ISO-induced cardiotoxicity as evident from the reduction in biochemical parameters. The expression of proinflammatory cytokines (IL-1β, IL-6 and TNF-α) showed significant decrease upon NY treatment. Histopathology and ECG showed protection in histoarchitecture and rhythm of heart, respectively. Reduction in hydroxyproline and TGF-β1 expression indicated antifibrotic activity. Conclusion: We report for the first time that NY ameliorates ISO-induced cardiac remodeling.

Abstract
Acute pancreatitis is an inflammatory disorder of the pancreas that may precipitate due to various reasons such as chronic alcoholism, gall stone obstruction, and life style. Current treatment options offer limited efficacy, as they provide only symptomatic relief. This study is an attempt to study the effects of Withaferin A (WFA) against Cerulein-induced acute pancreatitis in mice. Animals were pretreated with WFA via intraperitoneal route, for 7 days. Plasma amylase and lipase, tissue malondialdehyde (MDA), and glutathione were evaluated for all groups. Western blot analysis; haematoxylin and eosin staining of the liver, lung, and pancreas; immunohistochemistry for nitrotyrosine; and myeloperoxidase activity were performed. Haematoxylin and eosin stained sections significantly revealed the altered architecture and thereby damage in the pancreas, lungs, and liver that has been low in treatment groups. Increased myeloperoxidase and nitrotyrosine have also been reduced upon treatment with WFA. Increased levels of MDA, NO, and expression of myeloperoxidase and nitrotyrosine in the parameters estimated add evidence to the role of oxidative stress and inflammation in acute pancreatitis. WFA evidently altered these conditions upon pretreatment. Our study shows that this novel steroidal compound has potent anti-inflammatory property. Natural compounds can therefore be good remedies against many diseases if incorporated in routine diet as dietary supplement.
