[PMID: 36904028 PMCID: PMC10005287 DOI: 10.3390/plants12051168] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Subscribe] [Scholar Register] [Received: 02/02/2023] [Revised: 03/01/2023] [Accepted: 03/01/2023] [Indexed: 06/18/2023]
Abstract
Natural plants and their products continue to be the major source of phytoconstituents in food and therapeutics. Scientific studies have evidenced the benefits of sesame oil and its bioactives in various health conditions. Various bioactives present in it include sesamin, sasamolin, sesaminol, and sesamol; among these, sesamol represents a major constituent. This bioactive is responsible for preventing various diseases including cancer, hepatic disorders, cardiac ailments, and neurological diseases. In the last decade, the application of sesamol in the management of various disorders has attracted the increasing interest of the research community. Owing to its prominent pharmacological activities, such as antioxidant, antiinflammatory, antineoplastic, and antimicrobial, sesamol has been explored for the above-mentioned disorders. However, despite the above-mentioned therapeutic potential, its clinical utility is mainly hindered owing to low solubility, stability, bioavailability, and rapid clearance issues. In this regard, numerous strategies have been explored to surpass these restrictions with the formulation of novel carrier platforms. This review aims to describe the various reports and summarize the different pharmacological activities of sesamol. Furthermore, one part of this review is devoted to formulating strategies to improve sesamol's challenges. To resolve the issues such as the stability, low bioavailability, and high systemic clearance of sesamol, novel carrier systems have been developed to open a new avenue to utilize this bioactive as an efficient first-line treatment for various diseases.

Life Sci 2023; 316:121437. [PMID: 36702203 DOI: 10.1016/j.lfs.2023.121437] [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: 11/16/2022] [Revised: 01/03/2023] [Accepted: 01/20/2023] [Indexed: 01/25/2023]
Abstract
Obesity is an epidemic and a growing public health concern worldwide. It is one of the significant risk factors for developing chronic kidney disease. In the present study, we evaluated the preventive effect of green tea catechins (GTC) against obesity-induced kidney damage and revealed the underlying molecular mechanism of action. Various green tea catechins were quantified in the catechins-rich fraction using HPLC. In vitro, the palmitic and oleic acid-treated NRK-52E cells showed reduced fat accumulation and modulated expressions of PPARγ, CD36, and TGFβ after GTC treatment. In vivo, rats were fed with a high-fat diet (HFD), and the effect of GTC was assessed at 150 and 300 mg/kg body weight doses. HFD-fed rats showed a significant reduction in weight gain and improved serum creatinine, urea, and urine microalbumin levels after GTC treatment. The improved adipokines and insulin levels in GTC treated groups indicated the insulin-sensitizing effect. Histopathology revealed reduced degenerative changes, fibrous tissue deposition, and mesangial matrix proliferation in GTC treated groups. GTC treatment also downregulated the gene expressions of lipogenic and inflammatory factors and improved the altered expressions of CD36 and PPARγ in the kidney tissue. Further, GTC prevented gut dysbiosis in rats by promoting healthy microbes like Akkermansia muciniphila and Lactobacillus reuteri. Faecal metabolome revealed reduced saturated fatty acids, and improved amino acid levels in the GTC treated groups, which help to maintain gut health and metabolism. Overall, GTC prevented obesity-induced kidney damage by modulating PPARγ/CD36 signaling and maintaining gut health in rats.

Abstract
This study proposes a novel nature-inspired meta-heuristic optimizer based on the Reptile Search Algorithm combed with Salp Swarm Algorithm for image segmentation using gray-scale multi-level thresholding, called RSA-SSA. The proposed method introduces a better search space to find the optimal solution at each iteration. However, we proposed RSA-SSA to avoid the searching problem in the same area and determine the optimal multi-level thresholds. The obtained solutions by the proposed method are represented using the image histogram. The proposed RSA-SSA employed Otsu's variance class function to get the best threshold values at each level. The performance measure for the proposed method is valid by detecting fitness function, structural similarity index, peak signal-to-noise ratio, and Friedman ranking test. Several benchmark images of COVID-19 validate the performance of the proposed RSA-SSA. The results showed that the proposed RSA-SSA outperformed other metaheuristics optimization algorithms published in the literature.

Antioxidants (Basel) 2022; 11:antiox11091645. [PMID: 36139719 PMCID: PMC9495549 DOI: 10.3390/antiox11091645] [Citation(s) in RCA: 30] [Impact Index Per Article: 15.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/08/2022] [Revised: 08/13/2022] [Accepted: 08/24/2022] [Indexed: 12/24/2022] Open
Abstract
This study investigated the therapeutic effects of the phytochemical crocin alone or in combination with sorafenib both in rats chemically induced with hepatocellular carcinoma (HCC) and in human liver cancer cell line (HepG2). Male rats were randomly divided into five groups, namely, control group, HCC induced group, and groups treated with sorafenib, crocin or both crocin and sorafenib. HCC was induced in rats with a single intraperitoneal injection of diethylnitrosamine (DEN), then 2-acetylaminofluorene (2-AAF). The HCC-induced rats showed a significant decrease in body weight compared to animals treated with either or both examined drugs. Serum inflammatory markers (C-reactive protein (CRP); interleukin-6 (IL-6); lactate dehydrogenase (LDH), and oxidative stress markers were significantly increased in the HCC group and were restored upon treatment with either or both of therapeutic molecules. Morphologically, the HCC-induced rats manifested most histopathological features of liver cancer. Treatment with either or both of crocin and sorafenib successfully restored normal liver architecture. The expression of key genes involved in carcinogenesis (TNFα, p53, VEGF and NF-κB) was highly augmented upon HCC induction and was attenuated post-treatment with either or both examined drugs. Treatment with both crocin and sorafenib improved the histopathological and inflammation parameters as compared to single treatments. The in vivo anti-cancer effects of crocin and/or sorafenib were supported by their respective cytotoxicity on HepG2 cells. Crocin and sorafenib displayed an anti-tumor synergetic effect on HepG2 cells. The present findings demonstrated that a treatment regimen with crocin and sorafenib reduced liver toxicity, impeded HCC development, and improved the liver functions.

Abstract
Systemic inflammatory response syndrome plays an important role in the development of sepsis. GABAergic and cholinergic pathways activation are considered important for inflammatory response regulation. Tumor necrosis factor (TNF)-α, interleukin (IL)-1β, IL-12, IL-10, as well as inducible nitric oxide synthase (iNOS)-derived nitric oxide (NO) are important inflammatory mediators involved in the pathogenesis of sepsis. Muscimol, an active compound from the mushroom Amanita muscaria (L.) Lam., is a potent GABAA agonist, inhibits inflammatory response via activating GABAA receptor and vagus nerve. However, the effect of muscimol on lipopolysaccharide (LPS)-induced systemic inflammatory response is still unclear. Therefore, we studied the effects of muscimol on systemic inflammatory response and survival rate in endotoxemic mice. Mice endotoxemia was induced by LPS. Muscimol was given to mice or RAW264.7 cells 30 min before LPS (10 mg/kg, i.p., or 10 ng/mL, respectively). Mice received GABAergic and cholinergic receptor antagonists 30 min before muscimol and LPS. Muscimol decreased TNF-α, IL-1β, IL-12, iNOS-derived NO, and increased IL-10 levels and survival rate after LPS treatment. Muscimol significantly decreased nuclear factor kappa B (NF-κB) activity, increased IκB expression, and decreased pIKK expression in LPS-treated RAW264.7 cells. GABAergic and cholinergic antagonists failed to reverse muscimol's protection in LPS-treated mice. In conclusion, muscimol protected against systemic inflammatory response in endotoxemic mice may be partially independent of GABAergic and cholinergic receptors.

Abstract
Metaheuristics are proven solutions for complex optimization problems. Recently, bio-inspired metaheuristics have shown their capabilities for solving complex engineering problems. The Whale Optimization Algorithm is a popular metaheuristic, which is based on the hunting behavior of whale. For some problems, this algorithm suffers from local minima entrapment. To make WOA compatible with a number of challenging problems, two major modifications are proposed in this paper: the first one is opposition-based learning in the initialization phase, while the second is inculcation of Cauchy mutation operator in the position updating phase. The proposed variant is named the Augmented Whale Optimization Algorithm (AWOA) and tested over two benchmark suits, i.e., classical benchmark functions and the latest CEC-2017 benchmark functions for 10 dimension and 30 dimension problems. Various analyses, including convergence property analysis, boxplot analysis and Wilcoxon rank sum test analysis, show that the proposed variant possesses better exploration and exploitation capabilities. Along with this, the application of AWOA has been reported for three real-world problems of various disciplines. The results revealed that the proposed variant exhibits better optimization performance.

Effects of Sesame Consumption on Inflammatory Biomarkers in Humans: A Systematic Review and Meta-Analysis of Randomized Controlled Trials. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2021; 2021:6622981.

Abstract
Objectives Existing evidence produces conflicting findings regarding the effect of sesame intake on inflammatory biomarkers; this knowledge gap has yet to be met through systematic review and meta-analysis. This meta-analysis of randomized, controlled clinical trials (RCTs) was conducted to evaluate the effects of sesame consumption on markers of inflammation in humans. Methods PubMed, Scopus, and the Cochrane Database of Systematic Reviews were searched through August 2020 to identify relevant papers for inclusion. Using the random-effects model, data were evaluated as weighted mean differences (WMD) with 95% confidence intervals (CI). Cochrane's Q and I-squared (I2) tests were used to identify within-studies heterogeneity. Results Seven RCTs with 310 participants (157 intervention and 153 control) were included in the meta-analysis. Sesame consumption reduced serum level interleukin-6 (IL-6) (WMD − 0.90; 95% CI (−1.71, −0.09), I2 = 80.4%) compared to the control group. However, sesame intake had no significant effects on C-reactive protein (CRP) and tumor necrosis factor-α (TNF-α) compared to the control group. Subgroup analysis identified a reduction in serum CRP, TNF-α, and IL-6 concentration among studies with participants who had a higher level of these biomarkers at baseline, those which used sesamin capsules, and those with a bigger sample size, those conducted in Asia, and studies on females. Conclusion Sesame consumption reduced serum levels of IL-6 but did not affect CRP and TNF-α in humans. Additional trials should be conducted utilizing a larger and longer treatment duration, along with studies using different sesame formulations (capsule, oil, and seed) and conducting on participants with varied health conditions.

Abstract
The main goal of the present work was to develop a value-added product of biodegradable material for sustainable packaging. The use of agriculture waste-derived carboxymethyl cellulose (CMC) mainly is to reduce the cost involved in the development of the film, at present commercially available CMS is costly. The main focus of the research is to translate the agricultural waste-derived CMC to useful biodegradable polymer suitable for packaging material. During this process CMC was extracted from the agricultural waste mainly sugar cane bagasse and the blends were prepared using CMC (waste derived), gelatin, agar and varied concentrations of glycerol; 1.5% (sample A), 2% (sample B), and 2.5% (sample C) was added. Thus, the film derived from the sample C (gelatin + CMC + agar) with 2.0% glycerol as a plasticizer exhibited excellent properties than other samples A and B. The physiochemical properties of each developed biodegradable plastics (sample A, B, C) were characterized using Fourier Transform Infra-Red (FTIR) spectroscopy and Differential Scanning Calorimetry (DSC), Thermogravimetric analysis (TGA). The swelling test, solubility in different solvents, oil permeability coefficient, water permeability (WP), mechanical strength of the produced material was claimed to be a good material for packaging and meanwhile its biodegradability (soil burial method) indicated their environmental compatibility nature and commercial properties. The reflected work is a novel approach, and which is vital in the conversion of organic waste to value-added product development. There is also another way to utilize commercial CMC in preparation of polymeric blends for the packaging material, which can save considerable time involved in the recovery of CMC from sugarcane bagasse.

Abstract
Sesame (Sesamum indicum L.) seeds have been authenticated for its medicinal value in both
Chinese and Indian systems of medicine. Its numerous potential nutritional benefits are attributed to its
main bioactive constituents, sesamol. As a result of those studies, several molecular mechanisms are
emerging describing the pleiotropic biological effects of sesamol. This review summarized the most
interesting in vitro and in vivo studies on the biological effects of sesamol. The present work summarises
data available from Pubmed and Scopus database. Several molecular mechanisms have been elucidated
describing the pleiotropic biological effects of sesamol. Its major therapeutic effects have been
elicited in managing oxidative and inflammatory conditions, metabolic syndrome and mood disorders.
Further, compelling evidence reflected the ability of sesamol in inhibiting proliferation of the inflammatory
cell, prevention of invasion and angiogenesis via affecting multiple molecular targets and
downstream mechanisms. Sesamol is a safe, non‐toxic chemical that mediates anti‐inflammatory
effects by down‐regulating the transcription of inflammatory markers such as cytokines, redox status,
protein kinases, and enzymes that promote inflammation. In addition, sesamol also induces apoptosis
in cancer cells via mitochondrial and receptor‐mediated pathways, as well as activation of caspase cascades.
In the present review, several pharmacological effects of sesamol are summarised namely, antioxidant,
anti-cancer, neuroprotective, cardioprotective, anti-inflammatory, hypolipidemic, radioprotective,
anti-aging, anti-ulcer, anti-dementia, anti-depressant, antiplatelet, anticonvulsant, anti-anxiolytic,
wound healing, cosmetic (skin whitening), anti-microbial, matrix metalloproteinase (MMPs) inhibition,
hepatoprotective activity and other biological effects. Here we have summarized the proposed
mechanism behind these pharmacological effects.

A Review on Worldwide Ephedra History and Story: From Fossils to Natural Products Mass Spectroscopy Characterization and Biopharmacotherapy Potential. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2020; 2020:1540638. [PMID: 32419789 PMCID: PMC7210547 DOI: 10.1155/2020/1540638] [Citation(s) in RCA: 20] [Impact Index Per Article: 5.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/14/2020] [Revised: 04/08/2020] [Accepted: 04/16/2020] [Indexed: 02/07/2023]
Abstract
Growing worldwide, the genus Ephedra (family Ephedraceae) had a medicinal, ecological, and economic value. The extraordinary morphological diversity suggests that Ephedra was survivor of an ancient group, and its antiquity is also supported by fossil data. It has recently been suggested that Ephedra appeared 8–32 million years ago, and a few megafossils document its presence in the Early Cretaceous. Recently, the high analytical power provided by the new mass spectrometry (MS) instruments is making the characterization of Ephedra metabolites more feasible, such as ephedrine series. In this regard, the chemical compounds isolated from crude extracts, fractions, and few isolated compounds of Ephedra species were characterized by MS-based techniques (LC-MS, LC-ESI-MS, HPLC-PDA-ESI/MS, LC-DAD-ESI/MSn, LC/Orbitrap MS, etc.). Moreover, we carry out an exhaustive review of the scientific literature on biomedicine and pharmacotherapy (anticancer, antiproliferative, anti-inflammatory, antidiabetic, antihyperlipidemic, antiarthritic, and anti-influenza activities; proapoptotic and cytotoxic potential; and so on). Equally, antimicrobial and antioxidant activities were discussed. This review is focused on all these topics, along with current studies published in the last 5 years (2015–2019) providing in-depth information for readers.

Abstract
Background: Herbal medicine is becoming progressively accepted treatment for management of different diseases worldwide. Recognition of the active ingredients and mechanisms of herbal medicine against the immune system and related anomalies is highly favorable. This experimental study aimed to investigate the effects of Sesame (Sesamum indicum L.) essential oil and sesamol as effective components on mouse splenocytes subsets, macrophages and dendritic cells (DCs). Methods: Effective components of sesame were extracted and used to treat splenocytes, PHA (5μg/ml) and LPS (10 μg/ml) stimulated splenocytes, macrophages and DCs in different concentration (0.01-100 μg/ml). The cell proliferation/viability was measured using the MTT assay and nitrite levels were measured by the diazotization method. Moreover, TNF-α and IL-1β cytokines concentration were assayed by ELISA. Treated DCs also analysed for maturation marker levels and cytokine production. Results: Analysis of the results indicated that sesame components suppress PHA-stimulated splenocytes with no effect on LPS-stimulated subsets. Furthermore, the sesame ingredients reduced the release of IFN-γ and increased secretion of IL-4 from lymphocytes. Macrophages viability was not affected and production of NO, TNF-α, and IL-1β were inhibited using sesame essential oil and sesamol. DCs phenotype skewed to immature and release of TNF-α and IL-1β were abrogated form DCs. Conclusion: These results indicate that sesame essential oil and its effective component as sesamol may capable of suppressing the response of cellular immunity with the domination of Th2 responses and also could modulate macrophages and the dendritic cells proinflammatory functions.

Abstract
OBJECTIVES To evaluate the effects of topically and subconjunctivally administered sesamol on experimentally induced corneal neovascularization in rats. METHODS Fifty-six right eyes of 56 Wistar Albino rats were chemically cauterized to induce corneal neovascularization in this experimental and comparative study. The subjects were divided into eight groups: topical sesamol (group 1), subconjunctival sesamol (group 2), topical bevacizumab (group 3), subconjunctival bevacizumab (group 4), topical bevacizumab+ sesamol (group 5), subconjunctival bevacizumab+ sesamol (group 6), topical Tween 80 (group 7), and control (group 8). The amount of subconjunctivally injected sesamol and bevacizumab was 1.25 mg each. Topical groups were administered 10 mg/mL drops twice daily. The control group was left untreated. To evaluate the degree of corneal neovascularization, digital photographs and corneal sections stained with hematoxylin-eosin and CD31 were used. RESULTS When photographs of neovascularization areas were examined, all treatment groups showed statistically significant differences when compared with the control group (P<0.001). Topical sesamol was found to be more effective when compared with subconjunctival sesamol (P=0.003). Topical sesamol+ bevacizumab was found to be more effective when compared with topical bevacizumab (P=0.018). The numbers of new corneal vessels were as follows: 12.28±6.29 in group 1, 36.85±12.8 in group 2, 18.85±7.71 in group 3, 16.85±8.70 in group 4, 19.57±8.56 in group 5, 22.57±7.43 in group 6, 45.00±11.29 in group 7, and 51.16±5.91 in group 8 (P<0.001). CONCLUSIONS The outcomes of this study suggest antiangiogenic effects of sesamol. The use of topical sesamol monotherapy or sesamol combined with bevacizumab may be options for the prevention of corneal neovascularization.

Abstract
The aim of the present study was to evaluate the therapeutic potential of sesamol treatment on focal ischemia/reperfusion (I/R) injury in the rat brain. The results demonstrated that pretreatment with sesamol seven days prior to focal cerebral I/R injury had significant positive effects, including improvements in neurological deficits (P<0.05), and a reduction in malondialdehyde content and elevation of antioxidant levels (superoxide dismutase, glutathione and glutatione peroxidase; both P<0.05). Furthermore, levels of B cell lymphoma-2 (Bcl-2)-associated X protein and caspase-3 were significantly downregulated, whereas the level of Bcl-2 was effectively increased. Conversely, the mRNA expression of proinflammatory cytokines were significantly reduced in focal cerebral I/R injury rats upon sesamol intervention. Therefore, the beneficial effects of sesamol on cerebral I/R injury may be due to the reduction of oxidative stress, inhibition of apoptosis and inflammation. The findings of the present study suggest that sesamol supplementation may serve as potent adjuvant in the treatment of focal cerebral ischemia/reperfusion injury due to its neuroprotective effects.

Nanocrystalline cerium dioxide efficacy for prophylaxis of erosive and ulcerative lesions in the gastric mucosa of rats induced by stress. Biomed Pharmacother 2016; 84:1383-1392.

Abstract
In our previous works, the important therapeutic properties of nanocrystalline cerium dioxide such as strong antioxidant ability, prebiotical and antibiotic activity were shown. Such properties were obtained due to stabilization of nanoparticles with precise size 3-7nm. Such modification of nanocrystalline cerium dioxide has contributed to its remarkable efficacy and low toxicity. We have carried out the investigation of toxicity of the nanodrug and revealed that in the condition of the acute toxicity test, LD 50 was 2000mg/kg when it was administered per os. This indicator is approximately 1000 times greater than effective dose of the compound that proved the possibility of its usage for humans. Considering the strong antioxidant properties of this substance, we have performed the investigation of the influence of nanocrystalline cerium dioxide on the erosive-ulcerative lesions in gastric mucosa of rats induced by Selye's restraint stress. It was established that the studied compound significantly reduced the lesions area by 58.3% (p<0.05) induced by Selye's restraint stress. The attenuation of inflammation and decrease of lipid peroxidation in the conditions of gastric lesions and prophylactic administration of nanocrystalline cerium dioxide were shown. That was confirmed by the decrease of pro-inflammatory cytokines content (interleukin (IL) 1β, 12B p40) and raise of anti-inflammatory cytokines content (IL-10 and transforming growth factor β). Measurement of lipid peroxidation products has proved the antioxidant properties of nanocrystalline cerium dioxide as it decreased the content of conjugated dienes and thiobarbituric acid active products in the conditions of gastric ulceration induced by stress.

Abstract
AIM Chronic kidney disease causes a progressive and irreversible loss of renal function. We investigated the curative effect of sesame oil, a natural, nutrient-rich, potent antioxidant, in a rat model of chronic kidney disease. METHODS Chronic kidney disease was induced by subcutaneously injecting uni-nephrectomized rats with deoxycorticosterone acetate (DOCA) and 1% NaCl [DOCA/salt] in drinking water. Four weeks later, the rats were gavaged with sesame oil (0.5 or 1 mL/kg per day) for 7 days. Renal injury, histopathological changes, hydroxyl radical, peroxynitrite, lipid peroxidation, Nrf2, osteopontin expression, and collagen were assessed 24 h after the last dose of sesame oil. RESULTS Blood urea nitrogen, creatinine, urine volume, and albuminuria were significantly higher in the DOCA/salt treated rats than in control rats. Sesame oil significantly decreased these four tested parameters in DOCA/salt treated rats. In addition, creatinine clearance rate and nuclear Nrf2 expression were significantly decreased in the DOCA/salt treated rats compared to control rats. Sesame oil significantly decreased hydroxyl radical, peroxynitrite level, lipid peroxidation, osteopontin, and renal collagen deposition, but increased creatinine clearance rate and nuclear Nrf2 expression in DOCA/salt treated rats. CONCLUSION We conclude that supplementation of sesame oil mitigates DOCA/salt induced chronic kidney disease in rats by activating Nrf2 and attenuating osteopontin expression and inhibiting renal fibrosis in rats.

Anti-adipogenic effects of sesamol on human mesenchymal stem cells. Biochem Biophys Res Commun 2015; 469:49-54.

Abstract
Human mesenchymal stem cells (hMSCs) from adult bone marrow are able to differentiate into adipocytes, osteoblasts, chondrocytes and neuronal cells. Adipocytes in bone marrow are primarily responsible for the maintenance of bone structure by maintaining cell number balance with other stromal cells. However, the number of adipocytes in the bone marrow increases with age, leading to an imbalance of the bone marrow microenvironment, which results in a disruption of bone structure. In addition, the excessive number of adipocytes in bone marrow can cause diseases, such as osteoporosis or anemia. In this study, we investigated the effect of sesamol, a major natural phenolic compound of sesame oil, on the adipogenic differentiation of hMSCs. Numerous studies have reported the anti-oxidant property of sesamol, but its effect on cell differentiation has not yet been shown. We first found that sesamol treatment during adipogenic differentiation of hMSCs reduced intracellular lipid accumulation, which was unrelated to lipolysis. Interestingly, sesamol diminished the expression of genes responsible for adipogenesis, but increased the expression of osteogenic genes. In addition, sesamol decreased the expression of genes necessary for adipocyte maturation without affecting the expression of hMSC-specific genes. Studies concerning intracellular signaling in hMSCs showed that the extracellular signal-regulated kinase 1/2 (ERK1/2) was decreased by sesamol, which was similar with the effect of an ERK1/2 inhibitor. Overall, this study demonstrates that sesamol can attenuate the adipogenic differentiation of hMSCs without affecting its characteristics through the inhibition of ERK1/2 pathway. Herein, this study reports for the first time the effect of sesamol on hMSC differentiation and suggests the possibility of using sesamol as a therapeutic agent to treat intraosseous disruption triggered by the excessive adipogenesis of hMSCs.

Abstract
AIM: To investigate the protective effect of clodronate-containing liposomes against severe acute pancreatitis (SAP)-triggered acute gastric mucosal injury (AGMI) in rats.
METHODS: Clodronate- and phosphate-buffered saline (PBS)-containing liposomes were prepared by reverse-phase evaporation. The SAP rat model was established by injecting sodium taurocholate into the pancreatic subcapsular space. Sprague-Dawley rats were randomly divided into three groups: control (C), SAP plus PBS-containing liposome (P) and SAP plus clodronate-containing liposome (T). Serum tumor necrosis factor (TNF)-α levels were estimated by ELISA. Pathological changes in the gastric mucosa and pancreas were observed by hematoxylin and eosin (HE) staining. Apoptotic cells were detected by terminal deoxynucleotidyl transferase dUTP nick end labeling staining. The numbers of macrophages in the gastric mucosa were analyzed by CD68 immunohistochemical staining.
RESULTS: The liposomes had a mean diameter of 150 ± 30 nm. The TNF-α levels were significantly higher in the P group than that in the C group (2 h, 145.13 ± 11.50 vs 23.2 ± 2.03; 6 h, 245.06 ± 12.11 vs 30.28 ± 6.07, P < 0.05), and they were significantly lower in the T group than that in the P group (2 h, 93.24 ± 23.11 vs 145.13 ± 11.50; 6 h, 135.18 ± 13.10 vs 245.06 ± 12.11, P < 0.05). The pathological scores of the pancreas were lower in the T group than in the P group (2 h, 1.88 ± 0.83 vs 4.13 ± 0.83; 6 h, 2.87 ± 0.64 vs 6.25 ± 0.88, P < 0.01). The pathological scores of the gastric mucosa were also lower in the T group than in the P group (2 h, 1.12 ± 0.64 vs 2 ± 0.75; 6 h, 1.58 ± 0.53 vs 3 ± 1.31, P < 0.05). In addition, increased CD68 levels were observed in the gastric mucosa of the P group compared with the C group. Clodronate-containing liposomes decreased the CD68 levels in the mucosa of the T group. The apoptotic indexes of the gastric mucosa were higher in the T group than in the P group (2 h, 15.7 ± 0.92 vs 11.5 ± 1.64; 6 h, 21.12 ± 1.06 vs 12.6 ± 2.44, P < 0.01).
CONCLUSION: Gastric macrophages contribute to the pathogenesis of gastric injury in SAP. Clodronate-containing liposomes have protective effects against AGMI in rats with SAP.

Abstract
Sesame oil has been used in traditional Taiwanese medicine to relieve the inflammatory pain in people with joint inflammation, toothache, scrapes, and cuts. However, scientific evidence related to the effectiveness or action mechanism of sesame oil on relief of pain and inflammation has not been examined experimentally. Here, we investigated the therapeutic effect of sesame oil on monosodium urate monohydrate (MSU) crystal-induced acute inflammatory response in rats. Air pouch, a pseudosynovial cavity, was established by injecting 24 mL of filtered sterile air subcutaneously in the backs of the rats. At day 0, inflammation in air pouch was induced by injecting MSU crystal (5 mg/rat, suspended in sterilized phosphate buffered saline, pH 7.4), while sesame oil (0, 1, 2, or 4 mL/kg, orally) was given 6 h after MSU crystal injection. Parameters in lavage and skin tissue from the air pouches were assessed 6 h after sesame oil was given. Sesame oil decreased MSU crystal-induced total cell counts, tumor necrosis factor-α, interleukin (IL)-1β, and IL-6 levels in lavage and pouch tissue. Sesame oil significantly decreased leukocyte and neutrophil counts in lavage compared with MSU crystal alone group. Sesame oil decreased activated mast cell counts in skin tissue in MSU crystal-treated rats. Sesame oil significantly decreased nuclear factor (NF)-κB activity and IL-4 level in isolated mast cells from rats treated with MSU crystal. Furthermore, sesame oil decreased lavage complement proteins C3a and C5a levels in MSU crystal-treated rats. In conclusion, sesame oil shows a potent therapeutic effect against MSU crystal-induced acute inflammatory response in rats.
