Abstract
Background: Apoptosis disruptions play substantial roles in pathogenesis of arthritis and its symptoms. Cytokines and their intracellular signaling have pivotal roles in arthritis pathophysiology. This study aimed to investigate the relationship between synovial Interleukin-6 (IL-6), nuclear factor kappa-B (NF-ĸB), and fractalkine (FKN) in the changes of edema and apoptosis during adjuvantinduced knee arthritis. Methods: A total of 240 male Wistar rats were divided into different groups. Arthritis was evoked and the knee edema changes were evaluated by Vernier caliper. Synovial IL-6 was assayed by rat standard ELISA kit. Levels of NF-ĸB, fractalkine, and apoptotic indicators in the synovium were evaluated by Western blot method. Results were expressed as Mean± SEM. To analyze within-group variations, repeated measures ANOVA, followed by post hoc Tukey's test was used (SPSS, 16). Independent samples t test was used to designate significant differences in knee diameter, synovial level of IL-6, apoptotic markers, NF-ĸB, and FKN between groups. Significance level was set at P≤ 0.05. Results: The injection of Complete Freund's Adjuvant (CFA) caused intense knee edema (P< 0.001), which was reduced by implementing anti-IL-6 (P< 0.001), anti-FKN (P< 0.001), Inh-NF-ĸB (P< 0.001), and anti-FKN+ Inh NF-kB (P< 0.001). The results indicated elevated levels of apoptotic markers during the acute phase (P = 0.010), along with an increase in IL-6 (P< 0.001), NF-ĸB (P< 0.001), and FKN (P= 0.030). Although IL-6 (P< 0.001), NF-ĸB (P= 0.001), and FKN (P= 0.007) levels elevation continued during the chronic phase, the apoptosis markers decreased in this phase (P= 0.050). The findings revealed that Anti-IL-6 treatment during different phases of the study could change the synovial NF-ĸB and FKN. Conclusion: It seems that time-dependent variations in apoptotic markers level may be involved in pathogenesis of adjuvant-induced knee arthritis. In conclusion, synovial IL-6 through NF-ĸB- FKN pathway can play an important role in this process.

Abstract
Early diagnosis and treatment of acute ischemic stroke poses a significant challenge due to its suddenness and short therapeutic time window. Human endogenous cells derived biomimetic drug carriers have provided new options for stroke theranostics since these cells have higher biosafety and targeting abilities than artificial carriers. Inspired by natural platelets (PLTs) and their role in targeting adhesion to the damaged blood vessel during thrombus formation, we fabricated a biomimetic nanocarrier comprising a PLT membrane envelope loaded with l-arginine and γ-Fe2O3 magnetic nanoparticles (PAMNs) for thrombus-targeted delivery of l-arginine and in situ generation of nitric oxide (NO). Results demonstrate that the engineered 200 nm PAMNs inherit the natural properties of the PLT membrane and achieve rapid targeting to ischemic stroke lesions under the guidance of an external magnetic field. Subsequent to the release of l-arginine at the thrombus site, endothelial cells produce NO, which promotes vasodilation to disrupt the local PLT aggregation. Rapid targeting of PAMNs to stroke lesions as well as in situ generation of NO prompts vasodilation, recovery of blood flow, and reperfusion of the stroke microvascular. Thus, these PLT membrane derived nanocarriers are diagnostically beneficial for localizing stroke lesions and a promising modality for executing therapies.

Abstract
Either hypoxia in an acute ischemic stroke before thrombolysis or the oxygen-boost after thrombolysis cause a high level of free radicals, resulting in successive injuries to neurocytes. To treat an ischemic stroke, it is needed to scavenge free radicals, combining sequentially regulating hypoxia and oxygen-boost microenvironment. Here, we report an engineered nanosponge (Mn3O4@nanoerythrocyte-T7, MNET) that could remodel the microenvironment of a stroke by self-adapted oxygen regulating and free radical scavenging. With a long circulation time in blood due to the stealth effect of the erythrocyte and preferential accumulation in the infarct site by the assisting of T7 peptide, MNET exerts a distinct therapeutic effect in two stages of an ischemic stroke: (i) before thrombolysis, rescue neurocyte via rapid free radical scavenging and timely oxygen supply; (ii) after thrombolysis, suppress oxygen-boost via oxygen storage, as well as scavenge free radical to avoid reperfusion injury. MNET holds an attractive potential for ischemic stroke treatment via phased regulation of pathological microenvironment.

Abstract
Objectives The present study was conducted to investigate the protective effects of chamomile oil from Matricaria chamomilla against type 1 diabetes mellitus (T1DM) and its potential mechanisms. Methods T1DM was established in male New Zealand white rabbits via a single intraperitoneal infusion of streptozotocin (STZ) (80 mg/kg body weight−1, dissolved in 0.2 mL of normal saline). Different doses of chamomile oil (25, 50 and 100 mg/kg) were orally administrated to STZ induced diabetic rabbits for 21 consecutive days. The expression of pro-inflammatory cytokines was determined using ELISA assay. The expression of NF-κB and NLRP3 was measured using Western blot assay. Results Compared with normal rabbits, STZ-induced diabetic rabbits exhibited significant increased levels of blood glucose and decreased levels of serum insulin that were reversed using middle and high tested dose of chamomile oil. Likewise, STZ-induced diabetic rabbits showed a significant increased expression of NF-κB and NLRP3 proteins in the pancreas tissue that was reversed by high tested dose of chamomile oil. Conclusion Collectively, our findings demonstrated that chamomile oil possesses anti-hyperglycemic, and anti-inflammatory activities in STZ-induced diabetic rabbits by targeting inflammatory cytokines and NF-κB and NLRP3 signaling pathways.

Abstract
Alzheimer's disease (AD) is one of the most common age-associated brain diseases and is induced by the accumulation of amyloid beta (Aβ) and oxidative stress. Many studies have focused on eliminating Aβ by nanoparticle affinity; however, nanoparticles are taken up mainly by microglia rather than neurons, leading poor control of AD. Herein, mitochondria-targeted nanozymes known as (3-carboxypropyl)triphenyl-phosphonium bromide-conjugated 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[amino(polyethylene glycol)-2000]-functionalized molybdenum disulfide quantum dots (TPP-MoS2 QDs) were designed. TPP-MoS2 QDs mitigate Aβ aggregate-mediated neurotoxicity and eliminate Aβ aggregates in AD mice by switching microglia from the proinflammatory M1 phenotype to the anti-inflammatory M2 phenotype. TPP-MoS2 QDs cross the blood-brain barrier, escape from lysosomes, target mitochondria and exhibit the comprehensive activity of a bifunctional nanozyme, thus preventing spontaneous neuroinflammation by regulating the proinflammatory substances interleukin-1β, interleukin-6 and tumor necrosis factors as well as the anti-inflammatory substance transforming growth factor-β. In contrast to the low efficacy of eliminating Aβ by nanoparticle affinity, the present study provides a new pathway to mitigate AD pathology through mitochondria-targeted nanozymes and M1/M2 microglial polarization.

Abstract
BACKGROUND Herpes simplex virus (HSV) and poliovirus (PV) are both agents of major concern in the public health system. It has been shown that Dimorphandra gardneriana galactomannans can be used as solubilizer vehicles in the manufacturing of medicine. Mangiferin is the major constituent of Mangifera indica and presents multiple medicinal and biological activities. OBJECTIVE This study assayed the effect of D. gardneriana galactomannan combined with mangiferin (DgGmM) against HSV-1 and PV-1. METHODS The DgGmM cytotoxicity was evaluated by the colorimetric MTT method and the antiviral activity by plaque reduction assay, immunofluorescence and polymerase chain reaction (PCR), in HEp-2 cells. RESULTS The DgGmM showed a 50% cytotoxic concentration (CC50) > 2000 µg/mL. The 50% inhibitory concentrations (IC50) for HSV-1 and PV-1 were, respectively, 287.5 µg/mL and 206.2 µg/mL, with selectivity indexes (SI) > 6.95 for the former and > 9.69 for the latter. The DgGmM time-ofaddition protocol for HSV-1 showed a maximum inhibition at 500 µg/mL, when added concomitantly to infection and at the time 1 h post-infection (pi). While for PV-1, for the same protocol, the greatest inhibition, was also observed concomitantly to infection at 500 μg/mL and at the times 4 h and 8 h pi. The inhibition was also demonstrated by the decrease of fluorescent cells and/or the inhibition of specific viral genome. CONCLUSION These results suggested that the DgGmM inhibited HSV-1 and PV-1 replication, with low cytotoxicity and high selectivity and, therefore, represents a potential candidate for further studies on the control of herpes and polio infections.

Abstract
OBJECTIVES Liver ischemia-reperfusion injuries (I/RI) are typically the main causes of liver dysfunction after various types of liver surgery especially liver transplantation. Radical components are the major causes of such direct injuries. We aimed to determine the beneficial effects of silibinin, a potent radical scavenger on liver I/RI. MATERIALS AND METHODS Thirty-two rats were divided into 4 groups. Group I: VEHICLE, the rats underwent laparotomy and received DMSO, group II: SILI, laparotomy was done and silibinin was administered. Group III: I/R, the rats received DMSO and were subjected to a liver I/R procedure and group IV: I/R+SILI, the animals underwent the I/R procedure and received silibinin. After 1 hr of ischemia followed by 3 hr reperfusion, blood was collected to evaluate the serum marker of liver injuries. Hepatic tissue was harvested to investigate glycogen content, histological changes, and vasoregulatory gene expression. RESULTS Results showed that serum AST, ALT, LDH, GGT, ALP, and hyaluronic acid (HA) increased significantly in I/R group compared with the VEHICLE group. Silibinin reduced this elevation except for GGT. Silibinin inhibited hepatocyte vacuolization and degeneration, endothelium damages, sinusoidal congestion and inflammation, and glycogen depletion during I/R. ET-1 mRNA was overproduced in the I/R group compared with the VEHICLE group which was decreased by silibinin. KLF2 and eNOS expression was reduced during I/R compared with the VEHICLE group. Silibinin elevated KLF2 expression but had no meaningful effect on eNOS expression. CONCLUSION Silibinin protected the liver from I/RI. Silibinin could improve liver circulation by preventing sinusoidal congestion, inflammation, and perhaps modification of the vasoregulatory gene expression.

Abstract
Targeted drug delivery by nanoparticles (NPs) is an essential technique to achieve the ideal therapeutic effect for cancer. However, it requires large amounts of work to imitate the biomarkers on the surface of the cell membrane and cannot fully retain the bio-function and interactions among cells. Cell membranes have been studied to form biomimetic NPs to achieve functions like immune escape, targeted drug delivery, and immune modulation, which inherit the ability to interact with the in vivo environments. Currently, erythrocyte, leukocyte, mesenchymal stem cell, cancer cell and platelet have been applied in coating photothermal agents and anti-cancer drugs to achieve increased photothermal conversion efficiency and decreased side effects in cancer ablation. In this review, we discuss the recent development of cell membrane-coated NPs in the application of photothermal therapy and cancer targeting. The underlying biomarkers of cell membrane-coated nanoparticles (CMNPs) are discussed, and future research directions are suggested.

Targeting necroptotic cell death pathway by high-intensity interval training (HIIT) decreases development of post-ischemic adverse remodelling after myocardial ischemia / reperfusion injury. J Cell Commun Signal 2019; 13:255-267. [PMID: 30073629 PMCID: PMC6498245 DOI: 10.1007/s12079-018-0481-3] [Citation(s) in RCA: 23] [Impact Index Per Article: 4.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/16/2018] [Accepted: 07/11/2018] [Indexed: 12/21/2022] Open
Abstract
Regulated necrosis (necroptosis) plays a pivotal role in the extent of cardiomyocyte loss and the development of post-ischemic adverse remodelling and cardiac dysfunction following myocardial I/R injury. Although HIIT has been reported to give rise to cardioprotection against MI, but the detailed knowledge of its molecular targets for treatment of MI is still not available. The LAD of Male Wistar rats was occluded to induce MI for 30 min and reperfusion for eight weeks. We investigated the effect of long-term HIIT for eight weeks on lipid peroxidation, SOD activity and GSH content using ELISA assay. Cardiac function, fibrosis, and infarct size were assessed by echocardiography, Masson's trichrome and Evans Blue/TTC dual staining respectively. The expressions of gene markers of myocardial hypertrophy, fibrosis and key mediators of necroptosis were measured using RT-PCR and western blotting assay respectively. The results indicated that HIIT reduced lipid peroxidation, infarct size and improved endogenous antioxidant system and heart function. Significant decreases in mRNA levels of procollagen α1(I), α1(III), and fibronectin1were observed following HIIT. Moreover, that HIIT significantly decreased the expression of key mediators of necroptosis induced by MI (P < 0.05). There were no significant differences in β-MHC mRNA level in different groups. The findings of study suggest that HIIT might exert cardioprotective effects against post-ischemic adverse remodeling through targeting necroptosis process. Likewise, cardioprotective effects of HIIT in coping with myocardial I/R injury may be associated with RIP1-RIP3-MLKL axis. These findings establish a critical foundation for higher efficiency of exercise-based cardiac rehabilitation post-MI and future research.

Laskar AA, Danishuddin, Khan SH, Subbarao N, Younus H. Enhancement in the Catalytic Activity of Human Salivary Aldehyde Dehydrogenase by Alliin from Garlic: Implications in Aldehyde Toxicity and Oral Health. Curr Pharm Biotechnol 2019; 20:506-516. [PMID: 31038061 DOI: 10.2174/1389201020666190416140817] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/10/2018] [Revised: 02/23/2019] [Accepted: 04/09/2019] [Indexed: 11/22/2022]
Abstract
BACKGROUND Lower human salivary aldehyde dehydrogenase (hsALDH) activity increases the risk of aldehyde mediated pathogenesis including oral cancer. Alliin, the bioactive compound of garlic, exhibits many beneficial health effects. OBJECTIVE To study the effect of alliin on hsALDH activity. METHODS Enzyme kinetics was performed to study the effect of alliin on the activity of hsALDH. Different biophysical techniques were employed for structural and binding studies. Docking analysis was done to predict the binding region and the type of binding forces. RESULTS Alliin enhanced the dehydrogenase activity of the enzyme. It slightly reduced the Km and significantly enhanced the Vmax value. At 1 µM alliin concentration, the initial reaction rate increased by about two times. Further, it enhanced the hsALDH esterase activity. Biophysical studies indicated a strong complex formation between the enzyme and alliin (binding constant, Kb: 2.35 ± 0.14 x 103 M-1). It changes the secondary structure of hsALDH. Molecular docking study indicated that alliin interacts to the enzyme near the substrate binding region involving some active site residues that are evolutionary conserved. There was a slight increase in the nucleophilicity of active site cysteine in the presence of alliin. Ligand efficiency metrics values indicate that alliin is an efficient ligand for the enzyme. CONCLUSION Alliin activates the catalytic activity of the enzyme. Hence, consumption of alliincontaining garlic preparations or alliin supplements and use of alliin in pure form may lower aldehyde related pathogenesis including oral carcinogenesis.

Abstract
Ischemic cerebral stroke is a major cause of death and morbidity. Currently, no neuroprotective agents have been shown to impact the clinical outcomes in cerebral stroke cases. Here, we report therapeutic effects of Se nanoparticles on ischemic stroke in a murine model. Anti-transferrin receptor monoclonal antibody (OX26)-PEGylated Se nanoparticles (OX26-PEG-Se NPs) were designed and synthesized and their neuroprotective effects were measured using in vitro and in vivo approaches. We demonstrate that administration of the biodegradable nanoparticles leads to resolution of brain edema, protection of axons in hippocampus region, and myelination of hippocampal area after cerebral ischemic stroke. Our nanoparticle design ensures efficient targeting and minimal side effects. Hematological and biochemical analyses revealed no undesired NP-induced changes. To gain mechanistic insights into the therapeutic effects of these particles, we characterized the changes to the relevant inflammatory and metabolic signaling pathways. We assessed metabolic regulator mTOR and related signaling pathways such as hippo, Ubiquitin-proteasome system (ERK5), Tsc1/Tsc2 complex, FoxO1, wnt/β-catenine signaling pathway. Moreover, we examined the activity of jak2/stat3 signaling pathways and Adamts1, which are critically involved in inflammation. Together, our study provides a promising treatment strategy for cerebral stroke based on Se NP induced suppression of excessive inflammation and oxidative metabolism.

Abstract
The interactions between nanoparticles and humic acid (HA) are critical to understanding the environmental risks and applications of nanoparticles. However, the interactions between HA fractions and graphene oxide (GO, a popular carbon nanosheet) at the molecular level remain largely unclear. Four HA fractions with molecular weights ranging from 4.6 to 23.8 kDa were separated, and the large HA fractions presented low oxygen contents and many aromatic structures. The binding constants of the large HA fractions on GO were 2.6- to 3551-fold higher than those of the small HA fractions, while the maximum adsorption capacities of the larger HA fractions onto GO were much higher. Atomic force microscopy (AFM) found that the small and large HA fractions were spread over the center and the edge of the GO nanosheets, respectively. Density functional theory (DFT) simulation and nuclear magnetic resonance spectroscopy confirmed the above phenomena (three adsorption patterns, "vs", "ps", and "pea") and revealed that HA bonded to the GO nanosheets mainly through van der Waals force and π-π interactions. The integrating analysis of binding affinity, AFM, and DFT provides new insights into the environmental behavior of GO and the applications of GO in pollutant removal under exposure from HA.

Abstract
IMPACT STATEMENT Some six million cancer patients currently receive radiotherapy. Radiotherapy eliminates cancer cells by accelerating their death. However, radiotherapy is not selective, and it therefore harms healthy tissues around cancerous tissue. The latest studies have shown that the irradiation of biological materials causes a rapid increase in reactive oxygen species (ROS) in the tissue as a result of exposure of the target molecule to direct and indirect ionization. N-acetylcysteine (NAC) is an antioxidant that permits the elimination of free oxygen radicals and that contributes to glutathione synthesis. Our study, therefore, examined the effects of radiation resulting from radiotherapy on the small intestine at the molecular level, and prospectively considered the potential protective characteristics of NAC against gastrointestinal syndrome resulting from radiotherapy.

Abstract
IMPACT STATEMENT It has been stated that hesperidin has many pharmacological effects, such as anti-inflammatory and antioxidant effects, antimicrobial activity, and anti-carcinogenic activity; but hesperidin and its derivatives have been under investigation as anti-fertility factors for a very long time. However, our results show that hesperidin can improve mice follicular growth and maturation during in vitro 3D culture. Hesperidin as an antioxidant factor could enhance the mRNA expression levels of two important genes involved in folliculogenesis, PCNA, and FSH-R. Our results prove for the first time that hesperidin not only has deleterious effects on follicular development but can also increase rates of in vitro fertilization and embryo development.

Abstract
PURPOSE A potential therapeutic approach on skin flap necrosis is to target parallel pathways involved in necrosis. Azelaic Acid, Minoxidil and Caffeine combination was tried on skin flap survival by their possible interaction with ATP sensitive potassium (KATP) channels and nitric oxide pathway. MATERIAL AND METHODS Sprauge-Dawley rats were divided into 8 groups for skin flap surgery. Azelaic acid, minoxidil, caffeine, or their combination were applied topically in different groups. Two additional groups were treated with L-NAME or glibenclamide in addition to the combination therapy. Percentage of flap necrosis was calculated and flap samples were removed to measure tissue malondialdehyde (MDA) and nitric oxide (NO) and expression of inducible nitric oxide synthase (iNOS), Bcl-2 and Bax proteins. RESULTS Combination therapy profoundly decreased skin flap necrosis, tissue MDA contents, and expression of the pro-apoptotic protein Bax (p < 0.05 vs. single treatments). These effects were reversed by L-NAME and glibenclamide pre-treatments. Further evaluations showed combination therapy increases flap tissue NO content and iNOS expression (p < 0.05 vs. single treatments). CONCLUSION Beneficial effect of the combination therapy with azelaic acid, minoxidil and caffeine therapy on rescuing the flap from necrosis by targeting parallel signaling pathways suggested potential applications in clinical practice.

Abstract
OBJECTIVE To investigate the mechanisms underlying the neuroprotective effect of tacrolimus (FK506) on the hippocampal neurons of rats with status epilepticus (SE). METHOD A total of 126 male Wistar rats were randomly and equally divided into the control group, the epilepsy group, and the epilepsy + FK506 group. The epilepsy group and the epilepsy + FK506 group were both injected with pilocarpine to establish SE models. The epilepsy + FK506 group was pretreated with FK506 at 24 h and 1 h prior to pilocarpine injection. The contents of nitric oxide (NO), nitric oxide synthase (NOS), malondialdehyde (MDA), and apoptosis-inducing factor (AIF) of the hippocampus were measured. The expression of neuronal nitric oxide synthase (nNOS) and inducible nitric oxide synthase (iNOS) in the hippocampus was determined by immunohistochemistry. Mitochondrial membrane potential (MMP) and mitochondria size were also detected by flow cytometry. RESULTS FK506 could increase the survival of neurons in the hippocampus. Compared with the epilepsy group, the levels of NO, NOS (including nNOS and iNOS), and MDA were obviously decreased by FK506 (P < 0.05). Moreover, FK506 reversed the SE-induced MMP reduction and mitochondrial expansion (P < 0.05). Besides, compared with the epilepsy group, FK506 significantly increased the AIF level in the mitochondrial, but decreased that in the nuclear fractions, respectively (P < 0.05). CONCLUSION FK506 plays an important role in neuroprotection, possibly through suppressing oxidative stress and inhibiting the mitochondrial pathway of apoptosis.

Abstract
Introduction: Human amnion-derived mesenchymal stem cells (hAMSCs) have been used in the treatment of acute myocardial infarction. In the current study, we investigated the efficacy of hAMSCs for the treatment of chronic model of myocardial ischemia and heart failure (HF) in rats. Methods: Male Wistar rats weighing between 250 to 350 g were randomized into three groups: sham, HF control and HF+hAMSCs. For HF induction, animals were anesthetized and underwent left anterior descending artery ligation. In HF+hAMSCs group, 2×106 cells were injected into the left ventricular muscle four weeks post ischemia in the border zone of the ischemic area. Cardiac function was studied using echocardiography. Masson's trichrome staining was used for studying tissue fibrosis. Cells were transduced with green fluorescent protein (GFP) coding lentiviral vector. Immunohistochemistry was used for detecting GFP, vascular-endothelial growth factor (VEGF) and troponin T markers in the tissue sections. Results: Assessment of the cardiac function revealed no improvement in the myocardial function compared to the control HF group. Moreover, tissue fibrosis was similar in two groups. Immunohistochemical study revealed the homing of the injected hAMSCs to the myocardium. Cells were stained positive for VEGF and troponin T markers. Conclusion: injection of hAMSCs 4 weeks after ischemia does not improve cardiac function and cardiac muscle fibrosis, although the cells show markers of differentiation into vascular endothelial cells and cardiomyocytes. In sum, it appears that hAMSCs are effective in the early phases of myocardial ischemia and does not offer a significant advantage in patients with chronic HF.

Abstract
Presently, clinical nanomedicine and nanobiotechnology have impressively demanded the generation of new organic/inorganic analogues of graphene (as one of the intriguing biomedical research targets) for stem-cell-based tissue engineering. Among different shapes of graphene, three-dimensional (3D) graphene foams (GFs) are highly promising candidates to provide conditions for mimicking in vivo environments, affording effective cell attachment, proliferation,and differentiation due to their unique properties. These include the highest biocompatibility among nanostructures, high surface-to-volume ratio, 3D porous structure (to provide a homogeneous/isotropic growth of tissues), highly favorable mechanical characteristics, and rapid mass and electron transport kinetics (which are required for chemical/physical stimulation of differentiated cells). This review aims to describe recent and rapid advances in the fabrication of 3D GFs, together with their use in tissue engineering and regenerative nanomedicine applications. Moreover, we have summarized a broad range of recent studies about the behaviors, biocompatibility/toxicity,and biodegradability of these materials, both in vitro and in vivo. Finally, the highlights and challenges of these 3D porous structures, compared to the current polymeric scaffold competitors, are discussed.

Abstract
Renal ischemia/reperfusion (I/R) injury following kidney transplantation has been found to be a great clinical problem owing to initiation of acute inflammatory responses and subsequently rapid loss of kidney function. It is well known that lavender oil exhibits an extensive spectrum of pharmacological and biochemical activities. The purpose of this study was to clarify molecular targets of lavender in treatment of this disease. Male Wistar rats weighing 200-250 g were divided into three major groups: sham, I/R, and I/R + different doses of lavender oil (L1:50 mg/kg, L2: 100 mg/kg, and L3: 200 mg/kg). A rat model of renal I/R (45 min ischemia and 24 h reperfusion) was created and lavender was administrated at 1 h after the beginning of reperfusion (i.p). Activities of antioxidant enzymes such as SOD, GPX, and CAT, and lipid peroxidation were evaluated. The expression of inflammatory cytokines such as TNFα, IL1β, and IL10 was determined by IHC and ELISA assay. Apoptosis activity and tissue damage were evaluated by TUNEL and H & E staining, respectively. Our results showed that lavender oil markedly restored activities of antioxidant enzymes and reduced lipid peroxidation (P < 0.05). Lavender significantly decreased levels of TNFα and IL1β and increased level of IL10 in a dose-dependent manner (P < 0.05). Lavender reduced TUNEL positive cells in a dose-dependent manner. However, lavender reduced damage to peritubular capillaries and contributed to preservation of normal morphology of renal cells. In sum, our findings establish a fundamental foundation for future drug industry to decrease the rates of rejection in kidney transplant patients.

Abstract
Introduction: The aim of this research was to study the impact of various doxorubicin (Dox)-containing nanofluids, e.g. singlewalled carbon nanotube (SWCNT)+Dox, graphene oxide (GO)+Dox and DextranPNIPAM (copolymer)+Dox mixtures on HeLa cells (human transformed cervix epithelial cells, as a model for cancer cells) depending on their concentration. Methods: Structural analysis of GO+Dox complex was accomplished using Hartree-Fock level of theory in 6-31G** basis set in Gaussian. Dynamic light scattering (DLS), zeta-potential, scanning electron microscopy and confocal laser scanning microscopy were used. The cell viability was analyzed by the MTT assay. Results: The viability of HeLa cells was studied with the MTT assay after the incubation with various Dox-containing dispersions depending on their concentration. The size of the particles was determined by DLS. The morphology of the nanoparticles (NPs) was studied by scanning electron microscopy and their uptake into cells was visualized by confocal laser scanning microscopy. It was found that the Dextran-PNIPAM+Dox nanofluid in contrast to Dox alone showed higher toxicity towards HeLa cells up to 80% after 24 hours of incubation, whereas the SWCNT+Dox and GO+Dox nanofluids at the same concentrations protected cells from Dox. Conclusion: The importance of Dextran-PNIPAM copolymer as a universal platform for drug delivery was established, and the huge potential of Dextran-PNIPAM+Dox NPs as novel anticancer agents was noted. Based on the in vitro study of the SWCNT+Dox and GO+Dox nanofluids, it was concluded that SWCNT and GO NPs can be effective cytoprotectors against the highly toxic drugs.

Abstract
Migration of stem cells after transplantation reduces their therapeutic effects. In this study, we hypothesized that superparamagnetic iron oxide nanoparticles (SPION)-labeled mesenchymal stem cells (MSCs) in the presence of magnetic field may have a capability to increase regenerative ability after heart failure (HF). A rat model of ISO (isoproterenol)-HF was established to investigate the effects of SPION-labeled MSCs on tissue regeneration in the presence and absence of magnetic field. Hydrodynamic size, shape, and formation of chemical bonds between SPION and polyethylene glycol (PEG) were measured using dynamic light scattering (DLS), transmission electron microscopy (TEM), and Fourier-transform infrared spectroscopy (FTIR). The MRI was used to monitor SPION-labeled MSCs in vivo. Cell and tissue uptake of nanoparticles were determined by Prussian blue staining, atomic absorption spectroscopy (AAS), and inductively coupled plasma spectroscopy (ICP). Purity of the MSCs, heart function, myocardial fibrosis, and histologic damage were evaluated using flow-cytometry, echocardiography, Masson's trichrome, and H&E staining respectively. Various spectroscopic and microscopic analyses revealed that hydrodynamic size of SPION was 40 ± 2 and their shape was spherical. FTIR confirmed the presence of PEG on the surface of nanoparticles. The presence of magnetic field significantly increased cell homing. Highly purified MSCs population was detected by flow-cytometry. Using SPION-labeled MSCs in the presence of magnetic field markedly improved heart function and myocardial hypertrophy and reduced fibrosis (p < 0.05). Collectively, our results demonstrated that SPION-labeled MSCs in the presence of magnetic field might contribute to regeneration after HF.

Abstract
Ischemic stroke is a leading cause of death and disability worldwide and is in urgent need of new treatment options. The only approved treatment for stroke restores blood flow to the brain, but much of the tissue damage occurs during the subsequent reperfusion. Antioxidant therapies that directly address ischemia-reperfusion injury have shown promise in preclinical results. In this review, we discuss that reformulating antioxidant therapies as nanomedicine can potentially overcome the barriers that have kept these therapies from succeeding in the clinic. We begin by reviewing the pathophysiology of ischemic stroke with a focus on the effects of reperfusion injury. Next, we review nanotherapeutic systems designed to treat the disease with a focus on those addressing reperfusion injury. Mechanisms of passive and active transport required to traverse a blood–brain barrier are discussed. Finally, we conclude by outlining design parameters for potentially successful nanomedicines as front-line therapeutics for ischemic stroke.

Abstract
OBJECTIVE The mesenchymal stem cells derived from human amniotic membrane have the ability to secrete and release some factors that can promote the repair of damaged tissues. This secretome contains proteins and factors that reduce apoptosis and increase angiogenesis in the ischemia/reperfusion models. The present study was conducted to determine whether this secretome provides protection against transient focal cerebral ischemia. MATERIALS AND METHODS A rat model of focal cerebral ischemia was established through middle cerebral artery occlusion (MCAO) for 60 min and 24 h reperfusion. The amniotic mesenchymal stem cells-conditioned medium (AMSC-CM) at the dose of 0.5 μl was injected intracerebroventriculary (ICV) 30 min after reperfusion. Infarct volume, brain edema, neurobehavioral functions, and blood brain barrier (BBB) integrity were assessed 24 h after reperfusion. Neuronal loss and expression of caspase-3, Bax and Bcl-2 in motor cortex were evaluated by nissl staining and immunohistochemistry assay respectively. RESULTS ICV administration of AMSC-CM markedly reduced infarct volume, brain edema and the evans blue penetration rate compared with MCAO group (P < 0.05). Additionally, post-treatment with AMSC-CM significantly reduced neuronal loss, neurological motor disorders and expression of caspase-3, Bax and Bcl-2 in motor cortex compared with MCAO group (P < 0.05). CONCLUSION The results of this study indicate that treatment with AMSC-CM improves the pathological effects in the acute phase of cerebral ischemia. These findings establish a substantial foundation for stroke therapy and future research.

Abstract
BACKGROUND The study was conducted to examine therapeutic effects of lavender oil (LO) against myocardial infarction (MI) and its potential mechanisms. METHODS A rat model of MI was established and LO (100, 200 and 300 mg/kg) was intraperitoneally administrated immediately after ischemia. Anti-inflammatory and antioxidant activity of LO were evaluated by immunohistochemical assay and measurement of SOD, GSH, and MDA. The myocardial injury markers, apoptotic activity and infarct volume were examined by ELISA, TUNEL and TTC staining, respectively. RESULTS Compared with the control I/R-Vehicle, the expression of tumor necrosis factor-α (TNF-α) and interleukin-1β (IL-1β) significantly reduced 8 h after reperfusion and expression of interleukin-10 (IL-10) elevated 48 h after reperfusion in LO-treated rats (P < 0.05). Likewise, significant decreases in apoptotic activity, infarct volume and significant restoration of antioxidant endogenous defenses were observed in LO-treated rats (P < 0.05). CONCLUSION Collectively, these findings confirm that LO can be a good candidate to reduce injury after MI.

Abstract
SCOPE Testicular torsion and subsequent release of reactive oxygen species (ROS) can cause infertility in adults. Oxidative stress following testicular torsion plays an important role in the ýonset and development of apoptotic cell death through dysregulation of the cellular signaling pathways. Anti-inflammatory and antioxidant properties of capsaicin, a bioactive composition present in red peppers, has already been exploited for treatment of the cancer and pain relief. In present work, we evaluated the role of the mammalian target of rapamycin (mTOR) in antioxidant effect of capsaicin against reperfusion injury following testicular torsion. METHODS Male Wistar rats weighing 200-220 g were randomly assigned into four major groups: (i) a sham operated group, (ii) a testicular torsion (TT) group, (iii) three groups treated with different doses of capsaicin (TT + 100, 500 and 1000 μg/ml Cap), and (iv) three groups of healthy rats treated with different doses of capsaicin (100, 500 and 1000 μg/ml). Western blotting assay was used to examine the anti-apoptotic effects of capsaicin in testicular cells following torsion. H&E and TUNEL methods were used to evaluate testicular morphology and apoptosis activity. RESULTS Compared to control group, phosphorylation of mTOR was significantly increased in the TT groups. Capsaicin administration remarkably decreased the phosphorylation of mTOR at the highest dose (P < 0.05). Capsaicin decreased apoptosis and preserved tubular morphology in testes. CONCLUSION Our results showed that antioxidant properties of capsaicin minimizes cell death and reperfusion injury following testicular torsion.

Abstract
Testicular torsion-related oxidative stress causes a sequential chain of DNA damage, lipid peroxidation and cell death that leads to the derangement in the sperm functions and infertility. Capsaicin that has been applied for pain relief and cancer prevention possesses antioxidant properties which can be exploited to confer cell survival under ischaemic testis damage. Wistar male rats weighing 150-200 g were randomly divided into four groups: (i) sham group (all procedures except torsion of testis), (ii) ischaemia group (TT group), (iii) three TT groups treated with different dose of capsaicin (TT + different doses of Cap) and (iv) three control groups treated with different doses of capsaicin (100, 500 and 1000 ug/ml). Capsaicin administration significantly decreased the expression of pro-apoptotic factors and increased the expression of anti-apoptotic factors. Likewise, the expression of FOXO1 is significantly increased by higher doses of the capsaicin. Histological assessment by H&E and TUNEL method also exhibited an improved testicular morphology and decreased apoptosis in testes. These results suggested clinical potential for capsaicin in treatment of testicular torsion by targeting FOXO1 and apoptotic pathways.
