Abstract
INTRODUCTION The aim of this study was to compare the effect of five types of PEGlated nanoliposomes (PNLs) on α-synuclein (α-syn) fibrillization, attenuation of microglial activation, and silence of the SNCA gene, which encodes α-syn. METHODS To evaluate the inhibition of α-syn fibrillization, we used standard in vitro assay based on Thioflavin T (ThT) fluorescence. Next, to evaluate the attenuation of microglial activation, the concentration of TNF-a and IL-6 was quantified by ELISA assay in BV2 microglia cells treated with 100nM A53T α-syn and PNLs. In order to determine the silencing of the SNCA, real-time PCR and Western blot analysis was used. Finally, the efficacy of PNLs was confirmed in a transgenic mouse model expressing human α-syn. RESULTS ThT assay showed both PNL1 and PNL2 significantly inhibited a-syn fibrillization. ELISA test also showed the production of TNF-a and IL-6 was significantly attenuated when microglial cells treated with PNL1 or PNL2. We also found that SNCA gene, at both mRNA and protein levels, was significantly silenced when BV2 microglia cells were treated with PNL1 or PNL2. Importantly, the efficacy of PNL1 and PNL2 was finally confirmed in vivo in a transgenic mouse model. CONCLUSIONS In conclusion, the novel multifunctional nanoliposomes tested in our study inhibit α-syn fibrillization, attenuate microglial activation, and silence SNCA gene. Our findings suggest the therapeutic potential of PNL1 and PNL2 for treating synucleinopathies.

Abstract
OBJECTIVE According to the response-to-retention hypothesis, the inception of atherosclerosis is attributed to the deposition and retention of lipoprotein in the arterial intima, facilitated by altered proteoglycans with hyperelongated glycosaminoglycan (GAG) chains. Recent studies have elucidated a signaling pathway whereby transforming growth factor-β (TGF-β) promotes the expression of genes linked to proteoglycan GAG chain elongation (CHSY1 and CHST11) via reactive oxygen species (ROS) and the downstream phosphorylation of ERK1/2 and Smad2L. Atorvastatin is known to exhibit pleiotropic effects, including antioxidant and anti-inflammatory. The purpose of the present research was to ascertain the influence of atorvastatin on TGF-β-stimulated expression of CHSY1 and CHST11 and associated signaling pathways using an in vitro model. MATERIALS AND METHODS In this experimental study, vascular smooth muscle cells (VSMCs) were pre-incubated with atorvastatin (0.1-10 μM) prior to being stimulated with TGF-β (2 ng/ml). The experiment aimed to evaluate the phosphorylation levels of Smad2C, Smad2L, ERK1/2, the NOX p47phox subunit, ROS production, and the mRNA expression of CHST11 and CHSY1. RESULTS Our research results indicated that atorvastatin inhibited TGF-β-stimulated CHSY1 and CHST11 mRNA expression. Further experiments showed that atorvastatin diminished TGF-β-stimulated ROS production and weakened TGF-β-stimulated phosphorylation of p47phox, ERK1/2, and Smad2L; however, we observed no effect on the TGF-β- Smad2C pathway. CONCLUSION These data suggest that atorvastatin demonstrates anti-atherogenic properties through the modulation of the ROS-ERK1/2-Smad2L signaling pathway. This provides valuable insight into the potential mechanisms by which atorvastatin exerts its pleiotropic effects against atherosclerosis.

Abstract
Background Liver fibrosis, associated with hepatic stellate cells (HSCs), occurs when a healthy liver sustains damage, thereby impairing its function. NADPH oxidases (NOXs), specifically isoforms 1, 2, and 4, play a role in reactive oxygen species (ROS) production during hepatic injuries, resulting in fibrosis. Curcumin has shown strong potential in mitigating liver fibrosis. Our research aimed to investigate the effects of curcumin on lowering NOX and ROS levels. This compound was also studied for its effects on NOXs, ROS concentrations through the inhibition of Smad3 phosphorylation in transforming growth factor beta (TGF-β)-activated human HSCs. Methods MTT assay investigated the cytotoxic effects of curcumin on HSCs. The cells were activated by exposure to TGF-β (2 ng/mL) for 24 hours. After activating, the cells were treated with curcumin at 25-150 μM concentrations. After administering curcumin to the cells, we employed RT-PCR and Western blot techniques to evaluate the related gene and protein expression levels. This evaluation was primarily focused on the mRNA expression levels of NOX1, NOX2, NOX4 and phosphorylated Smad3C. Results The mRNA expression level of aforesaid NOXs as well as α-smooth muscle actin (α-SMA), collagen1-α, and ROS levels were significantly reduced following 100 μM curcumin treatment. Furthermore, curcumin significantly decreased the p-Smad3C protein level in TGF-β-activated cells, with fold changes of 3 and 2 observed at 75 and 100 μM, respectively. Conclusion Curcumin decreased the levels of ROS and NOX, as well as the expression of α-SMA and collagen1-α. The primary mechanism for this reduction could be linked to the level of p-Smad3C. Hence, curcumin could serve as an effective therapeutic agent for liver fibrosis.

Abstract
BACKGROUND Quercetin (QC) is a naturally occurring flavonoid found in abundance in fruits and vegetables. Its anti-cancer and anti-inflammatory properties have been previously demonstrated, but its low bioavailability hampers its clinical use. Triple-negative breast cancer is a subtype of breast cancer with a poor response to chemotherapy. This study investigates the anti-cancer effects of quercetin-solid lipid nanoparticles (QC-SLN) on the triple-negative breast cancer cell line MDA-MB231. MATERIALS AND METHODS MCF-7 and MDA-MB231 cells were treated with 18.9 µM of QC and QC-SLN for 48 h. Cell viability, apoptosis, colony formation assay, and the anti-angiogenic effects of the treatment were evaluated. RESULTS QC-SLN displayed optimal properties (particle size of 154 nm, zeta potential of -27.7 mV, encapsulation efficiency of 99.6%, and drug loading of 1.81%) and exhibited sustained release of QC over 72 h. Compared to the QC group, the QC-SLN group showed a significant decrease in cell viability, colony formation, angiogenesis, and a substantial increase in apoptosis through the modulation of Bax and Bcl-2 at both gene and protein levels. The augmentation in the proportion of cleaved-to-pro caspases 3 and 9, as well as poly (ADP-ribose) polymerase (PARP), under the influence of QC-SLN, was conspicuously observed in both cancer cell lines. CONCLUSIONS This study showcases quercetin-solid lipid nanoparticles (QC-SLN) as a promising therapy for triple-negative breast cancer. The optimized QC-SLN formulation improved physicochemical properties and sustained quercetin release, resulting in reduced cell viability, colony formation, angiogenesis, and increased apoptosis in the MDA-MB231 cell line. These effects were driven by modulating Bax and Bcl-2 expression, activating caspases 3 and 9, and poly (ADP-ribose) polymerase (PARP). Further in vivo studies are needed to confirm QC-SLN's efficacy and safety.

Abstract
Background Currently, liver fibrosis is growing worldwide; unfortunately, there is no definite cure for this disease. Hence, understanding the molecular pathways involved in the development of liver fibrosis can help to find a proper treatment. In this study, we aimed to evaluate the effects of isorhamnetin as an antifibrotic agent on platelet-derived growth factor (PDGF)-BB-activated hepatic stellate cells (HSC)-T6 cells in a concentration-dependent manner. We have also attempted to assess signaling pathways that may affect liver fibrosis. Methods PDGF-BB was used to activate the HSC-T6 rat hepatic stellate cell line. The activated cells were treated with Isorhamnetin for 24 h. Finally, we compared the mRNA expression level of COLA1 and α-SMA and also the level of phosphorylated AKT protein with the control group. Results The obtained data revealed a significant increase in the expression level of the COLA1 and α-SMA genes (p > 0.05), as well as phosphorylated AKT protein, in the cells treated with PDGF-BB. In addition, 75 and 100 µM concentrations of Isorhamnetin markedly declined the COLA1 and α-SMA expression and also the phosphorylated AKT protein level in the HSC-T6 cells. Conclusion Our findings suggest that Isorhamnetin decreases HSC-T6 activation, the expression of COLA1 and α-SMA, in vitro, which could act as an antifibrotic element to reduce and treat liver fibrosis disease.

Abstract
Background Elevated brain cholesterol increases the risk of Alzheimer's disease. Production of 24-hydroxycholesterol (24s-OHC) by neurons prevents cholesterol accumulation in the brain. In this study, we investigated the effect of 24s-OHC on the HMG-COA reductase and ABCA1 which are involved in the brain cholesterol homeostasis with or without β-amyloid in astrocytes. Methods and Materials Astrocytes were treated with 24s-OHC with or without Aβ. Western blot and real-time polymerase chain reaction were done to detect protein and gene expression of β-hydroxy-3-methyl-glutaryl-coenzyme A reductase (HMGCR) and ABCA1, respectively. Cholesterol release was determined using a quantitation kit. Results Protein levels of HMGCR and ABCA1 were significantly increased by Aβ; however, the 24s-OHC was able to restore their levels and diminish the effect of amyloid-β. Aβ did not have a significant effect on HMGCR expression, while 24s-OHC reduced it by 68%. Aβ-induced ABCA1 expression did not increase cholesterol efflux as the lower levels of cholesterol in conditioned medium of Aβ-treated cells were found. Conclusion Our novel findings show that Aβ affects two key elements in the brain cholesterol homeostasis, HMGCR and ABCA1, which are crucial in cholesterol synthesis and efflux. Since 24s-OHC could suppress the Aβ effects on enhancement of HMGCR and ABCA1, therefore the cytochrome P450 46A1 (Cyp46A1), which is exclusively expressed in the central nervous system and responsible for producing of 24s-OHC, could consider as a therapeutic target in the cholesterol-related neurodegenerative diseases such as Alzheimer's disease.

Abstract
Atherosclerosis, a leading cause of cardiovascular disease, remains a significant global health concern. Tamoxifen and raloxifene, selective estrogen receptor modulators (SERMs), have demonstrated potential cardioprotective effects. However, the underlying molecular mechanisms by which these SERMs modulate Transforming Growth Factor-β (TGF-β) signaling in human vascular smooth muscle cells (VSMCs) remain largely unexplored. This study sought to investigate the impact of tamoxifen and raloxifene on TGF-β-induced CHSY1 expression and Smad2 linker region phosphorylation in VSMCs and to elucidate the role of reactive oxygen species (ROS), NADPH oxidase (NOX), and kinase pathways in mediating these effects. Employing a comprehensive experimental strategy, VSMCs were treated with TGF-β in the presence or absence of tamoxifen, raloxifene, and various pharmacological inhibitors. Subsequently, CHSY1 mRNA expression, Smad2C and Smad2L phosphorylation, ROS production, p47phox and ERK 1/2 phosphorylation were assessed. Our results revealed that tamoxifen and raloxifene significantly attenuated TGF-β-mediated CHSY1 mRNA expression and Smad2 linker region phosphorylation, without affecting the canonical TGF-β-Smad2C pathway. Furthermore, these compounds effectively inhibited ROS production, p47phox and ERK 1/2 phosphorylation, implicating the involvement of the TGF-β-NOX-ERK-Smad2L signaling cascade in their cardioprotective properties. This study provides a comprehensive understanding of the molecular mechanisms underlying the cardioprotective effects of tamoxifen and raloxifene in VSMCs, offering valuable insights for the development of targeted therapeutic strategies aimed at atherosclerosis prevention and the promotion of cardiovascular health.

Abstract
BACKGROUND The presence of cancer stem cells (CSCs) is a major cause of resistance to cancer therapy and recurrence. Triple-negative breast cancer (TNBC) is a subtype that responds poorly to therapy, making it a significant global health issue. Quercetin (QC) has been shown to affect CSC viability, but its low bioavailability limits its clinical use. This study aims to increase the effectiveness of QC in inhibiting CSC generation by using solid lipid nanoparticles (SLNs) in MDA-MB231 cells. MATERIALS AND METHODS After treating MCF-7 and MDA-MB231 cells with 18.9 μM and 13.4 μM of QC and QC-SLN for 48 h, respectively, cell viability, migration, sphere formation, protein expression of β-catenin, p-Smad 2 and 3, and gene expression of EMT and CSC markers were evaluated. RESULTS The QC-SLN with particle size of 154 nm, zeta potential of -27.7 mV, and encapsulation efficacy of 99.6% was found to be the most effective. Compared to QC, QC-SLN significantly reduced cell viability, migration, sphere formation, protein expression of β-catenin and p-Smad 2 and 3, and gene expression of CD44, zinc finger E-box binding homeobox 1 (ZEB1), vimentin, while increasing the gene expression of E-cadherin. CONCLUSIONS Our findings demonstrate that SLNs improve the cytotoxic effect of QC in MDA-MB231 cells by increasing its bioavailability and inhibiting epithelial-mesenchymal transition (EMT), thereby effectively inhibiting CSC generation. Therefore, SLNs could be a promising new treatment for TNBC, but more in vivo studies are needed to confirm their efficacy.

Abstract
Background: Hepatocellular carcinoma (HCC) is the most common type of liver cancer worldwide. The current remedies for cancer, including chemotherapy and radiation therapy, might damage patients’ organs, sometimes causing death. Etoposide (ETO), as a widely used chemo-drug, possesses the same problems. For years, combinational therapy has been considered a potential adjustor for common treatments, alleviating their side effects. Quercetin (Que), a phytochemical drug, has been used due to its potential against cancer. Objectives: This study explored whether synergy occurs between Que and ETO on the apoptosis of HepG2 HCC cells or not. Methods: The impacts of the drugs on cell growth were assessed through the MTT assay. The apoptotic death rates of treated cells were examined through Annexin/PI double staining and caspase-9 and caspase-3 activities. The relative expression of B-cell lymphoma 2 (Bcl-2) Associated X-protein (Bax), and Bcl-2 genes and proteins were analyzed using quantitative reverse transcription polymerase chain reaction and western blot analysis. Additionally, the levels of p53 protein were determined. Results: Both Que and ETO reduced the cell viability and increased apoptotic rates, caspases activities, Bax gene and protein expression, and the p53 protein levels of HepG2 cells. The combination of Que and ETO showed apparent synergy in terms of cell growth and cell apoptosis. Que significantly enhanced the effects of ETO on caspase activities, Bax and Bcl-2 genes’ expression, and p53 protein levels. Conclusions: The obtained results demonstrated that Que showed synergy when co-treated with ETO on HepG2 cells. Therefore, it is concluded that further studies on the aforementioned combination could lead to a potential anticancer compound against HCC.

Abstract
BACKGROUND The use of complementary and/or alternative medicine to increase the efficacy and decrease the side effects of current cancer treatment is highly required. In this in-vivo study, we aimed to investigate the anti-tumor activity and probable side effects of a natural treatment, Cyrtopodion scabrum extract (CsE), in a model of tumor bearing mice. METHODS We established 28 female CT26-tumor bearing balb/c-mice model. We divided them randomly into four groups (n=7): Negative control received distilled water (DW) and the three treatment groups were administered with 5-FU and two different doses (300 and 600 mg/kg) of the gecko aqueous extract, respectively. The changes in the tumor volumes and weights during and after treatment, along with the blood cell counts; spleen and thymus indices were assessed in the treatment groups. We have also measured the serum TNF-α, VEGF, AST, ALT and GSH, as well as the physical activities of the experimental mice. RESULTS We found that the means of tumor weights and volumes in both CsE and 5-FU treated groups were significantly lower than the untreated group (p<0.05). Serum TNF-α and VEGF levels in both CsE treated groups were remarkably lower than 5-FU and untreated groups (p<0.05). The 5-FU treatment caused a remarkably decrease in serum GSH, RBC count, WBC count, thymus index, and spleen index , while CsE treatment maintained these quantities, with no significant changes, compared to the control group. AST and ALT were not significantly changed in none of the treated groups compared to control. CONCLUSION Altogether, data suggest C. scabrum, as an effective and safe anti-cancer natural source, which could be used as an alternative/complementary medicine for the treatment of patients who suffer from colon cancer.

Abstract
Objectives Free cholesterol in the diet can cause liver fibrosis by accumulating in Hepatic stellate cells (HSCs). The rate of mortality of this disease is high worldwide and there is no definite remedy for it, but might be treated by anti-fibrotic therapies. MSCs-derived exosomes are known as the new mechanism of cell-to-cell communication, showing that exosomes can be used as a new treatment. In this study, we investigated the ability of exosomes of WJ-MSCs as a new remedy to reduce cholesterol-induced liver fibrosis in the LX2 cell line. Materials and Methods MSCs were isolated from Wharton's jelly of the umbilical cord and the exosomes were extracted. The LX2 cell line was cultured in DMEM medium with 10% FBS, then cells were treated with 75 and 100 μM concentrations of cholesterol for 24 hr. The mRNA expression of TGF-β, αSMA, and collagen1α genes, and the level of Smad3 protein were measured to assess liver fibrosis. Results Cholesterol increased the expression of TGF-β, αand -SMA, and collagen1α genes by increasing the phosphorylation of the Smad3 protein. Treatment with Exosomes significantly reduced the expression of TGF-β, α-SMA, and collagen1α genes (fibrosis genes). Treatment with exosomes prevented the activation of HSCs by inhibiting the phosphorylation of the Smad3 protein. Conclusion The exosomes of WJ-MSCs can inhibit the TGFβ/Smad3 signaling pathway preventing further activation of HSCs and progression of liver fibrosis. So, the exosomes of WJ-MSCs s could be introduced as a treatment for liver failure.

Abstract
Mesenchymal stem cells (MSCs) have the ability to phagocytize amyloid beta (Aβ) plaques and lower inflammation through the activity of microglia. Peroxisome proliferator-activated receptor gamma (PPARγ) is a protein involved in reducing inflammation through the activity of microglia and the phagocytosis of Aβ plaques by scavenger receptor CD36, in this study, the effect of MSCs therapy on memory function and plaques was investigated. A total of 24 adult male Wistar rats were randomly divided into three groups:1) the control group, 2) the Aβ-treated group (Alzheimer's disease (AD)), and 3) the MSC-treated group (AD + MSC). After the treatment with Aβ and MSCs, western blotting and real-time polymerase chain reaction (PCR) techniques were used to assess protein and gene expression levels, respectively. MSCs improved spatial learning and memory in the AD group (p ≤0.05). The expression levels of PPARγ, lncRNA TUSC7, and CD36 genes were significantly elevated in the group receiving MSCs compared to the AD group (p≤0.0001). Also, the expression level of miR-449a significantly decreased in the AD + MSC group (p≤0.0001). Moreover, western blot analysis revealed that PPARγ and CD36 protein levels were enhanced in the AD + MSC group compared to the AD group (p≤0.0001). MSC treatment led to the positive regulation of the PPARγ gene and its protein expression by ncRNAs, which could have a beneficial impact on CD36 protein levels, and subsequently, reduce the number of plaques in the cell recipient.

Abstract
Objectives Activated cells which are called star-shaped cells, are some of the key factors in the development of liver fibrosis. Activation of NADPH oxidase (NOX) is associated with increased HSCs activity and progression of hepatic fibrosis. In this study, the effects of human exosomes derived from WJ-MSCs on NOX1, NOX2, and NOX4 gene expression in TGF-β-induced hepatic fibrosis were investigated. Materials and Methods LX2 cell line was treated with 2 ng/ml TGF-β for 24 hr, in order to induce liver fibrosis after starvation. In the next step, the cells were treated with several concentrations of the exosomes derived from WJ-MSCs (10, 20, 30, 40, and 50 μg/ml). Finally, Smad3C phosphorylated protein expression level and NOX1, NOX2, and NOX4 gene expression levels were measured. Results The results demonstrated that the level of NOX1, NOX2, and NOX4 mRNA expressions decreased significantly during 24 hrs at concentrations of 40 and 50 μg/ml of WJ-MSCs exosomes in TGF-β-induced-HSCs. The p-Smad3C proteins were significantly decreased (fold change: 1.83, P-value<0.05) after exposure to WJ-MSC-derived exosomes. Conclusion Treatment with exosomes prevents further activation of HSCs by inhibiting the level of Smad3C phosphorylation. The experimental data of our study suggested that in liver fibrosis, the protection of HSCs activation against TGF-β by inhibiting the NOX pathway via human exosomes of WJ-MSCs is extremely important. It needs further research as a treatment method.

Abstract
Objective Breast cancer is the leading cause of death among women in many countries. Numerous factors serve as oncogenes or tumor suppressors in breast cancer. The large family of Tripartite-motif (TRIM) proteins with ~ 80 members has drawn attention for their role in cancer. TRIM3 and TRIM16 have shown suppressive activity in different cancers. This study aimed to evaluate the expression of TRIM3 and TRIM16 in cancerous and normal breast samples and to investigate their association with different clinical and pathological parameters. Results qRT-PCR was utilized to determine the gene expression of TRIM3 and TRIM16. The expression of TRIM3 and TRIM16 genes in tumor samples were significantly reduced to 0.45 and 0.29 fold, respectively. TRIM3 and TRIM16 genes expression were both positively correlated with the invasion of breast cancer. TRIM3 gene expression was associated with tumors’ histological grade. However, no significant association was found between the expression of the genes and tumor size, stage and necrosis. The expression of TRIM3 and TRIM16 are significantly reduced in breast cancer tissues. Besides, the expression of both TRIM3 and TRIM16 genes significantly plummet in lymphatic/vascular and perineural invasive samples. Hence, we suggest a potential tumor suppressor role for TRIM3 and TRIM16 in breast cancer.

Abstract
Caveolin-1(Cav-1) is one of the most important components of caveolae in the cell membrane, which plays an important role in cell signaling transduction, such as EGFR and TGF-β receptor transactivation. The purpose of this study was to evaluate the effect of c-Abl and NAD(P)H oxidases (NOX) on phosphorylation of Cav-1 and consequently their effect on phosphorylation of Smad2C induced by Endothelin-1 in human vascular smooth muscle cells (VSMCs). In this study, all experiments were performed using human VSMCs. The phosphorylation level of the Caveolin-1 and Smad2C proteins were assessed by western blotting using Phospho-Caveolin-1 (Tyr14) antibody and phospho-Smad2 (Ser465/467) antibody. The data were reported as mean ± SEM. The VSMCs treated with endothelin-1(ET-1) (100 nanomolar (nmol)) demonstrated a time-dependent increase in the pCav-1 level (p<0.05). The inhibitors of NOX (diphenyleneiodonium) (p<0.05), cholesterol depleting agent (beta-cyclodextrin) (p<0.05) and c-Abl inhibitor (PP1) (p<0.01) were able to reduce the level of the phospho-Cav-1 and phospho-Smad2C induced by Et-1 (p<0.05). Our results proposed that caveolae structure, NOX, c-Abl played an important role in the phosphorylation of Cav-1 induced by ET-1 in the human VSMCs. Furthermore, our findings showed that phosphoCav-1 involved in TGFR transactivation. Thus, Et-1 via a transactivation-dependent mechanism can cause phosphorylation of Smad2C.

Abstract
Objective Growth factors [transforming growth factor-β (TGF-β), epidermal growth factor (EGF), endothelin-1 (ET-
1)] stimulate proteoglycan synthesis resulting in retention and accumulation of low density lipoprotein (LDL) in vessel
intima and leading to atherosclerosis development. This study investigated the role of ET-1 on the expression of
CHSY1, proteoglycan synthesizing enzyme, through both EGF and TGF-β receptor transactivation in human vascular
smooth muscle cells (VSMCs). Also, we explored the involvement of NADPH oxidase (NOX), an important intermediate
of redox signaling, in ET-1 transactivated EGF receptor (EGFR) through endothelin receptors.
Materials and Methods In this experimental study, phosphorylated ERK1/2 and CHSY1 protein levels in the human
VSMCs were measured by Western blot analysis using anti phospho-ERK1/2 (Thr202/Tyr204) and anti CHSY1
antibodies.
Results ET-1 (100 nM) and EGF (100 ng/ml) stimulated ERK1/2 phosphorylation and inhibited in the presence of
bosentan (ET receptor inhibitor), AG1478 (EGFR inhibitor), and DPI (NOX antagonist). Also, ET-1 treatment increased
CHSY1 enzyme level; this response was suppressed by bosentan, AG1478, DPI, and SB431542, TGF-β receptor
antagonist. This study revealed that ET-1 increases expression of CHSY1 through transactivation of EGF and TGF-β
receptors.
Conclusion Transactivation through the EGF receptor mediated by phospho-ERK1/2 leads to expression of CHSY1
protein. EGF receptor transactivation by ET-1 is shown for the first time, to be dependent on NOX enzymes.

Abstract
Resveratrol is a phenol compound produced by some plants in response to pathogens, infection, or physical injury. It is well-known that resveratrol has antioxidant and protective roles in damages potentially caused by cancer or other serious disorders. Thus, it is considered as a candidate agent for the prevention and treatment of human diseases. Evidence has confirmed other bioactive impacts of resveratrol, including cardioprotective, anti-tumorigenic, anti-inflammatory, phytoestrogenic, and neuroprotective effects. Ischemia-reperfusion (IR) can result in various disorders, comprising myocardial infarction, stroke, and peripheral vascular disease, which may continue to induce debilitating conditions and even mortality. In virtue of chronic ischemia or hypoxia, cells switch to anaerobic metabolism, giving rise to some dysfunctions in mitochondria. As the result of lactate accumulation, adenosine triphosphate levels and pH decline in cells. This condition leads cells to apoptosis, necrosis, and autophagy. However, restoring oxygen level upon reperfusion after ischemia by producing reactive oxygen species is an outcome of mitochondrial dysfunction. Considering the neuroprotective effect of resveratrol and neuronal injury that comes from IR, we focused on the mechanism(s) involved in IR injury in the nervous system and also on the functions of resveratrol in the protection, inhibition, and treatment of this injury.

Abstract
OBJECTIVES Breast cancer (BC) cells' ability to metastasize to other tissues increases mortality. The Matrix metalloproteinases 2 and 9 (MMP-2 and MMP-9) facilitate cancer cell migration. 5-fluorouracil is a frequently applied chemotherapeutic agent in cancer treatment with destructive side effects on normal tissues. Hence, researchers have focused on finding a way to reduce the dose of chemotherapeutic drugs. Quercetin, a natural polyphenolic compound, has inhibitory effects on proliferation and migration of tumor cells. This study evaluated the effect of the combination of Quercetin and 5-fluorouracil on migration of the MDA-MB-231 breast cancer cell line. MATERIALS AND METHODS The effect of Quercetin, 5-fluorouracil , and their combination on MDA-MB-231 breast cancer cell proliferation was investigated through MTT assay. Inhibition of tumor cell migration was examined by wound healing assay. Finally, the effect of treatments on gene expression of MMP-2 and MMP-9 was evaluated by quantitative real-time PCR. RESULTS The IC50 values for Quercetin and 5-fluorouracil after 48 hr treatment were 295 μM and 525 μM, respectively. The combination index (CI) for Quercetin and 5-fluorouracil was <1, indicating synergy between them. The combination of Quercetin plus 5-fluorouracil resulted in a significant reduction in migration rate and MMP-2 and MMP-9 gene expressions of MDA-MB-231 cancer cells compared with the individual application of 5-FU. CONCLUSION Quercetin enhances the suppressory effect of 5-fluorouracil on migration of BC cells. The combination of Quercetin and 5-fluorouracil can be an attractive field for future studies.

Abstract
AIMS Diabetes mellitus is a metabolic disease that manifested as hyperglycemia due to the defect in secretion or function of insulin. This study aimed was to survey about frequency type I and II diabetes in newly diagnosed diabetic patients base on c-peptide and anti-glutamate acid decarboxylase (GAD) tests. MATERIALS & METHODS This study was conducted as a prospective study on 70 diabetic patients aged 15-45 years old who referred to diabetes clinics in Ahvaz city during 2012-2014 and their diabetes was diagnosed for the first time, but their type of diabetes was not clinically definitive. Patients with anti-GAD positive and fasting C-peptide level of less than 0.65 were diagnosed as type I diabetes. Patients with anti-GAD negative fasting C-peptide level of greater than or equal to 0.65 were considered as type II diabetes. RESULTS Eighty two patients (49 males and 33 females) with a mean age of 21.64 ± 4.36 years (range 15-34) and a mean BMI of 22.05 ± 4.41 kg/m2 (range 14-18) were studied. Twenty three patients (28.5%) had type I diabetes and 59 patients (71.95%) had type II diabetes. In patients with type I diabetes, the mean BMI was 24.86 ± 2.36 kg/m2 and the number of patients with family history (56.22%) was higher. In type II diabetic patients, the number of women (62.71%) was higher than that of men. CONCLUSION Anti-GAD test can be used as a predictive test for early diagnosis of disease and screening of people with a diagnosis of diabetes based on the type of diabetes.

Abstract
BACKGROUND Iranian borage, Echium amoenum, is believed to improve reproduction according to folk medicine. Although E. amoenum distillate known as "Aragh Gav-zaban" is widely consumed as a safe and natural remedy, its possible effects on fertility have not yet been scientifically examined. The present study aimed to investigate the effects of borage distillate (BD) on reproductive parameters of male mice. METHODS In this experimental study, 30 adult male Mus musculus mice (30-35 g) were equally divided into three groups. The control group received distilled water (DW) for five weeks and the other two groups, BD1/2 and BD1/4, received borage distillate of 1/2 dilution (150±2.5 ml/kg/day) and 1/4 dilution (75±1.25 ml/kg/day), respectively, ad libitum for three weeks and DW for 2 weeks. On the day 35, mice were sacrificed, sperm analysis was performed, and sera were collected to evaluate gonadotropins, testosterone, and toxicity parameters. The left testis was excised for stereological study and the right testis was used to evaluate androgen receptor (AR) gene expression. RESULTS The administration of BD1/2 significantly increased serum FSH (P=0.004), LH (P=0.025), testosterone (P=0.014), the percentage of motile (P=0.011); slow progressive (P=0.001), coiled tail (P<0.001) sperms, and the number of Leydig cells (P=0.008) compared to the control group. Treatment with BD1/4 significantly increased sperm count (P=0.044) and motile sperms percentage (P=0.040) compared to the control group too. The administration of BD revealed no significant effects on toxicity parameters and AR gene expression. CONCLUSION The findings of the present study showed that the consumption of borage distillate, as a safe herbal remedy, improves hormonal and sperm parameters in male mice.

Abstract
Chronic obstructive pulmonary disease (COPD) has been defined by the Global Initiative for Chronic Obstructive Lung Disease (GOLD), as a disease state characterized by airflow limitation which is not fully reversible. COPD consists of emphysema which is the destruction and inflammation of the lung alveoli. Adenosine deaminase (ADA, E.C.3.5.4.4) converts adenosine to inosine. There are two isoenzymes of ADA in serum; ADA1 and ADA2. It has been established that in COPD patients the adenosine levels increase, which can contribute to decrease of ADA activity. In this research we studied the ADA and its isoenzyme activity in COPD patients. This descriptive analytical case-control study was performed on thirty patients who were hospitalized in the pulmonary wards with an acute exacerbation of COPD. ADA activity was determined in 30 COPD patients, 30 nonsmokers and 30 smokers controls. All subjects were male. We used colorimetric (Giusti) method for measuring of ADA activity. The data were analyzed using SPSS 13 software and Kruskall-Wallis and two-way ANOVA tests. Total ADA activity in the COPD and smoker control groups was significantly lower than in non smoker group (18.99 -/+ 7, 19.03 -/+ 9.1 and 22.95 -/+ 6.7 U/L, respectively). There was a significant difference for ADA2 between the three groups. Whereas the ADA1 activity in the three groups had no significant difference. Based on the obtained data, decrease of ADA activity may play an important role in the formation of pulmonary injury in COPD patients.

Abstract
This study was performed to estimate prevalence of transaminase levels in type 2 diabetic patients and identify contributing risk factors. In this cross-sectional study 348 patients with type 2 diabetes, who attended the diabetic clinic of Yazd Diabetes Research Center, were studied from October 2004 to December 2005. Patients with history of viral hepatitis, alcohol abuse and use of drug such as Amiodarone, Bleomycin, methotrexate, tamoxifen and sodium valporate was excluded. To examine the relationships between ALT, AST in individuals with type II diabetes and relation to various metabolic parameters like triglyceride, cholesterol, age, duration of diabetes, gender and BMI. Of 348 patients that entered the study, mean age was 58.8 +/- 11.5. Elevated ALT and AST were found in 10.4 and 3.3% of type 2 diabetic patients, respectively. Although the prevalence of elevated ALT increased with increasing age, FBS and triglyceride levels in subjects, but it was not statistically significant. There was a significant association between elevated ALT and gender as well as diabetes duration. The prevalence of elevated of ALT in type 2 diabetic patients is 1.6 times higher than general population in Iran unrelated to age, BMI, glycemic control, triglyceride levels. Identification risk factors and mechanisms of these elevations are very important and require further evaluation.

Abstract
PURPOSE To study the 4 years incidence of diabetic retinopathy in patients with type II diabetes and effective factors on its progression. METHODS Among diabetic patients referred to Yazd Diabetes Research Center, 120 patients with type II diabetes without diabetic retinopathy were selected. After complete ophthalmic examination, fasting blood sugar (FBS), postprandial blood sugar, triglyceride, and cholesterol were measured and height, weight, and blood pressure (BP) were recorded. Then patients were followed with eye examination yearly for 4 years. RESULTS Four-year cumulative incidence of diabetic retinopathy was 47.5% (95% CI: 38.6-56.4). The retinopathy was mild nonproliferative diabetic retinopathy (NPDR) in 43 (35.8%) whereas 10 (8.3%) patients had moderate NPDR, 3 (2.5%) patients had severe NPDR, and only one patient had proliferative diabetic retinopathy. The incidence of diabetic retinopathy was 5.8% in first year, 20.3% in the second year, 24.4% in the third year, and 7.4% in the fourth year. Duration of diabetes, FBS, and systolic BP had statistically significant relation with grades of diabetic retinopathy. However, there was no significant association between age, sex, body mass index, triglyceride, cholesterol, method of treatment, smoking, and diastolic BP with grades of diabetic retinopathy. CONCLUSIONS These data provide 4-year cumulative incidence of diabetic retinopathy in defined type 2 diabetic patients. The present study shows that duration of diabetes, hyperglycemia, and systolic BP appear to be the major factors associated with the development of any level of retinopathy in type 2 diabetic patients.

Abstract
SETTING Afghanistan. OBJECTIVE To describe the results of rapid expansion of the DOTS strategy in a post-conflict environment, with a focus on the experience of the Rural Expansion of Afghanistan's Community-based Healthcare (REACH) Program. RESULTS Despite the destruction of the National Tuberculosis Program (NTP) and basic health services by war and an uncertain security situation, the NTP, with assistance from many partners and REACH, increased the number of patients receiving DOTS by 136% in 4 years (from 9261 cases in 2001 to 21851 in 2005), with an 86% treatment success rate. By focusing on rapidly expanding the number of facilities capable of providing tuberculosis (TB) diagnostic and treatment services and involving community health workers in case detection, referrals and home-based DOTS, REACH showed a 10-fold rise in the number of facilities providing TB services and a 380% increase in the number of sputum smear-positive pulmonary TB cases detected in 2 years (from 251/month in 2004 to 818/month in 2006) in 13 provinces. CONCLUSION At the current rate of expansion, case detection and successful treatment of TB cases in Afghanistan will continue to expand rapidly. The NTP and REACH have demonstrated that expansion of TB services in Afghanistan is possible despite the challenges.
