Abstract
BACKGROUND In many diabetic patients, spermatogenesis complications are frequent causing infertility problems. This study aimed to demonstrate the effect of Forskolin on male reproductive dysfunction caused by type 2 diabetes. MATERIALS AND METHODS In this experimental study, type 2 diabetes was induced by a high-fat diet (HFD) for one month and then a low single dose injection (35 mg/kg) of streptozotocin (STZ) in Wistar rats. After 72 hours, rats with more than 200 mg/dl of blood glucose were considered type 2 diabetic rats. Forty rats (200-250 g) were divided into four groups (n=10) including group 1 (G1): rats with normal diet and buffer citrate (STZ solvent) injection, group 2 (G2): control type 2 diabetic rats with HFD and STZ injection, group 3 (G3): type 2 diabetic rats received phosphate buffer saline (PBS) as Forskolin solvent, and group 4 (G4): Forskolin treated diabetic rats (10 mg/kg) for 1 month. RESULTS In comparison to control group, in diabetic groups (G2 and G3) some parameters are increased significantly: The blood glucose (P=0.00078), testicular malondialdehyde (MDA) level and body weight (P=0.00009) and Bax gene expression (P=0.00007). Unlike, some parameters are decreased significantly: The serum level of testosterone (P=0.0009), testicular superoxide dismutase (SOD, P=0.00007) and glutathione peroxidase (GPX) levels (P=0.00008), sperm concentration (P=0.00008), motility (P=0.00009), normal morphological sperm (P=0.00008) and Bcl-2 gene expression (P=0.00009). However, in Forskolin treated group (G4) the parameters stayed close to control values that was significantly (P=0.00007) higher than in G2 and G3 groups. Therefore, treatment with Forskolin significantly improved these abnormal changes in Forskolin-treated group. CONCLUSION Our study demonstrates that Forskolin is an effective antidiabetic agent, which significantly improves sperm concentration, testosterone levels, and antioxidant activity in diabetic rats.

Abstract
This study aimed to investigate the effects of metformin and forskolin independently and in combinations on the sperm quality parameters and sexual hormones of diabetic male rats. Fifty adult male rats were divided randomly into five identical groups, and diabetes mellitus was induced to the rats, except for the rats in the control group, using a high-fat diet and injection of Streptozotocin. Daily administration of metformin and forskolin independently and in combinations were performed for 8 weeks in different groups. Sperm quality parameters (including sperm count, morphology, sperm motility and Johnson score), testosterone, blood sugar level, Bax to Bcl-2 ratio mRNA expression level and oxidative stress levels were measured and compared between the investigated groups. Treating diabetic rats with metformin and forskolin resulted in significant improvement in sperm quality parameters, increased testosterone levels, reduced oxidative stress in blood and testicular tissue, and decreased blood sugar, and Bax to Bcl-2 ratio level. Although the combination of metformin with forskolin had a higher effect in some parameters such as testosterone levels compared to treatment with metformin or forskolin alone, this combination had not shown a synergistic effect in all the sperm quality parameters. Metformin and forskolin are effective anti-diabetic agents, which significantly improve the sperm quality and sexual hormone levels in diabetic rats. Combining metformin and gorskolin resulted in significantly better testosterone level and antioxidant activity in blood serum without significant effect on sperm quality of diabetic rats.

Abstract
Spinal cord injury (SCI) can result in significant neurological impairment and functional and cognitive deficits. It is well established that SCI results in focal neurodegeneration that gradually spreads to other cord areas. On the other hand, traumatic brain injury (TBI) is strongly associated with tau protein pathology and neurodegeneration that can spread in areas throughout the brain. Tau is a microtubule-associated protein abundant in neurons and whose abnormalities result in neuronal cell death. While SCI and TBI have been extensively studied, there is limited research on the relationship between SCI and brain tau pathology. As a result, in this study, we examined tau pathology in spinal cord and brain samples obtained from severe SCI mouse models at various time points. The effects of severe SCI on locomotor function, spatial memory, anxiety/risk-taking behavior were investigated. Immunostaining and immunoblotting confirmed a progressive increase in tau pathology in the spinal cord and brain areas. Moreover, we used electron microscopy to examine brain samples and observed disrupted mitochondria and microtubule structure following SCI. SCI resulted in motor dysfunction, memory impairment, and abnormal risk-taking behavior. Notably, eliminating pathogenic cis P-tau via systemic administration of appropriate monoclonal antibodies restored SCI's pathological and functional consequences. Thus, our findings suggest that SCI causes severe tauopathy that spreads to brain areas, indicating brain dysfunction. Additionally, tau immunotherapy with an anti-cis P-tau antibody could suppress pathogenic outcomes in SCI mouse models, with significant clinical implications for SCI patients. SCI induces profound pathogenic cis p-tau, which diffuses into the brain through CSF, resulting in brain neurodegeneration and cognitive decline.

Abstract
Proprotein convertase subtilisin/kexin type 9 (PCSK9), as a vital modulator of low-density lipoprotein cholesterol (LDL-C) , is raised in hepatocytes and released into plasma where it binds to LDL receptors (LDLR), leading to their cleavage. PCSK9 adheres to the epidermal growth factor-like repeat A (EGF-A) domain of the LDLR which is confirmed by crystallography. LDLR expression is adjusted at the transcriptional level through sterol regulatory element binding protein 2 (SREBP-2) and at the post translational stages, specifically through PCSK9, and the inducible degrader of the LDLR PCSK9 inhibition is an appealing new method for reducing the concentration of LDL-C. In this review the role of PCSK9 in lipid homeostasis was elucidated, the effect of PCSK9 on atherosclerosis was highlighted, and contemporary therapeutic techniques that focused on PCSK9 were summarized. Several restoration methods to inhibit PCSK9 have been proposed which concentrate on both extracellular and intracellular PCSK9, and they include blockage of PCSK9 production by using gene silencing agents and blockage of it's binding to LDLR through antibodies and inhibition of PCSK9 autocatalytic processes by tiny molecule inhibitors.

Abstract
The integrity of the structural cerebral cortex is disrupted after stroke either at the macroscopic or microscopic levels. Therefore, many attempts have been gathered to circumvent stroke-associated problems in the brain tissue. The current study was aimed to design an animal model of photochemical stroke using rose bengal (RB) plus laser irradiation (L) after 10, 15, and 20 min (´) and evaluate its effect on the cerebral tissue using unbiased stereological quantitative methods and morphometric histological analysis. Photochemical stroke was induced by intraperitoneal injection of RB dye and further activation through the exposure of the right sensorimotor cortex with the green laser radiation (100 mW; 532 nm). Mice were randomly allocated into 4 groups (each in 15) as follows: control (10 μg/gbw RB), RB + 10'L, RB + 15'L, and RB + 20'L. Target irradiation site was adjusted to 2 mm lateral to the bregma. Vernier caliper morphometric evaluation, cresyl violet staining, and unbiased stereological assays including Cavalier's principle and point counting techniques were used to monitor the pathological changes and lesion volume on days 1, 3, and 7 after the ischemia induction. Our data showed that the mean diameter of the lesion site and lesion infarct volume in the group RB + 20'L) was significantly increased relative to the other groups (P < 0.05). Notably, the lesion volume and diameter in the group RB + 15'L was larger compared with the group RB + 10'L and control mice (P < 0.05). Data showed an increased acute inflammatory response such as hyperemia and edema 3 days after ischemic induction while the intensity of acute changes and lesion volume were reduced and replaced with necrotic and chronic pathological changes including astrogliosis on day 7. It is concluded that the laser irradiation of RB-injected mice at a distinct time period could induce the magnificent degenerative effects on the cerebral cortex which is similar to the stroke condition.

Abstract
Doxorubicin (DOX) is one of the secondary metabolites of Streptomyces peucetius var. caesius. It is a common and effective chemotherapeutic agent used for the treatment of different diseases, including lymphoma, leukemia, breast cancer, and solid tumors. However, this medicine causes cardiotoxic side effects, which limit its clinical application. The present study examined the cardiomyopathy induced by DOX via echocardiography and transmission electron microscopy (TEM). The main objective was to evaluate the capacity of echocardiography and TEM as diagnostic tools for DOX-induced cardiotoxicity. Moreover, the correlation between intracellular and functional changes due to cardiotoxicity was assessed in a rat model. Cardiomyopathy was induced in rats by two cumulative doses of DOX. Group I received DOX 12 [i.e., 12 mg/kg, intraperitoneal (IP)] and group II received DOX 15 (i.e., 15 mg/kg, IP) in six equal doses over two weeks. Group III as the control (Ctrl) group received normal saline as a vehicle. Mortality during the study was only observed in the DOX 15 group. The echocardiographic assessments revealed significant changes in ejection fraction, fractional shortening, and heart rate in the groups which received DOX. In addition, severe cardiac arrhythmia was evident in DOX-treated groups. Remarkable adverse effects, such as moderately degenerated cells and inflated mitochondria were observed in the TEM analysis of rat hearts in the DOX groups. The present study indicated that rat models are suitable for investigating DOX-induced cardiomyopathy, especially at the dose of 12 mg/kg. Furthermore, echocardiography and TEM examinations were found to be valuable methods for the determination of cardiotoxicity in rats due to DOX.

Abstract
Alzheimer's disease (AD) is a progressive neurodegenerative disease with high outbreak rates. It is estimated that about 35 million individuals around the world suffered from dementia in 2010. AD is expected to increase twofold every 20 years and, by 2030, approximately 65 million people could suffer from this illness. AD is determined clinically by a cognitive impairment and pathologically by the production of amyloid beta (Aβ), neurofibrillary tangles, toxic free radicals and inflammatory mediators in the brain. There is still no treatment to cure or even alter the progressive course of this disease; however, many new therapies are being investigated and are at various stages of clinical trials. Neuropeptides are signaling molecules used by neurons to communicate with each other. One of the important neuropeptides is apelin, which can be isolated from bovine stomach. Apelin and its receptor APJ have been shown to broadly disseminate in the neurons and oligodendrocytes of the central nervous system. Apelin-13 is known to be the predominant neuropeptide in neuroprotection. It is involved in the processes of memory and learning as well as the prevention of neuronal damage. Studies have shown that apelin can directly or indirectly prevent the production of Aβ and reduce its amounts by increasing its degradation. Phosphorylation and accumulation of tau protein may also be inhibited by apelin. Apelin is considered as an anti-inflammatory agent by preventing the production of inflammatory mediators such as interleukin-1β and tumor necrosis factor alpha. It has been shown that in vivo and in vitro anti-apoptotic effects of apelin have prevented the death of neurons. In this review, we describe the various functions of apelin associated with AD and present an integrated overview of recent findings that, in general, recommend apelin as a promising therapeutic agent in the treatment of this ailment.

Abstract
Even though citalopram is commonly used in psychiatry, there are several reports on its toxic effects. So, the current study was designed to elucidate the mechanisms of cytotoxic effects of in vitro and in vivo citalopram treatment on liver and the following cytolethal events. For in vitro experiments, freshly isolated rat hepatocytes were exposed to citalopram along with/without various agents. To do in vivo studies liver function enzyme assays and histological examination were performed. In the in vitro experiments, citalopram (500 µM) exposure demonstrated cell death, a marked elevation in ROS formation, mitochondrial potential collapse, lysosomal membrane leakiness, glutathione (GSH) depletion and lipid peroxidation. In vivo biochemistry panel assays for liver enzymes function (AST, ALT and GGTP) and histological examination confirmed citalopram (20 mg/kg)-induced damage. citalopram-induced oxidative stress cytotoxicity markers were significantly prevented by antioxidants, ROS scavengers, MPT pore sealing agents, endocytosis inhibitors, ATP generators and CYP inhibitors. Either enzyme induction or GSH depletion were concomitant with augmented citalopram-induced damage both in vivo and in vitro which were considerably ameliorated with antioxidants and CYP inhibitors. In conclusion, it is suggested that citalopram hepatotoxicity might be a result of oxidative hazard leading to mitochondrial/lysosomal toxic connection and disorders in biochemical markers which were supported by histomorphological studies.

Abstract
BACKGROUND Alzheimer's disease (AD) is an age-related progressive neurodegenerative disease, which is characterized clinically by serious impairment in memory and cognition. Current medications only slow down the dementia progression and the present treatment one-drug one-target paradigm for anti-AD treatment appears to be clinically unsuccessful. Therefore, alternative therapeutic strategies are urgently needed. With respect to multifunctional and multitargeted characteristics of Rosa damascena via its effective flavonoids, we investigated the effects of R. damascena extract on behavioral functions in a rat model of amyloid-β (A-β)-induced Alzheimer's disease. MATERIALS AND METHODS After preparation of the methanolic extract of the R. damascena, HPLC analysis and toxicity studies, median lethal dose (LD50) and dose levels were determined. For evaluation of baseline training behavioral performance, Morris water maze and passive avoidance tests were used. A-β was injected bilaterally into CA1 area of the hippocampus. Twenty-one days after injection of A-β, the first probe trial of the behavioral tests were used to confirm learning and memory impairment. To examine the potential effects of the extract on behavioral tasks, the second probe trials were performed after one month administration of R. damasena extract. RESULTS Results showed that the R. damascena extract significantly improved the spatial and long-term memories in the extract- treated groups in a dose-dependent manner, as in the middle and high doses it had significant effect. CONCLUSION According to these results, we concluded that R. damascena can reverse behavioral deficits caused by A-β, and may provide a new potential option for prevention and treatment of the cognitive dysfunction in Alzheimer's disease.

Abstract
Background: Experimental autoimmune encephalomyelitis (EAE) is an animal model of multiple sclerosis, which is a demyelinating and an inflammatory disease of central nervous system. Recent studies have established that some molecules such as Lipocaline2 (LCN2), which expresses during inflammatory conditions, play an important role in EAE pathogenesis and might involve in its treatment process. Recently, it has been proved that MS14, an herbal-marine drug, has anti-inflammatory properties through reduction of TNF-α and IL-1β. Thus, the present study investigated the effects of MS14 on the course of EAE and its relation to LCN2 expression in both protein and gene levels. Methods: EAE was induced in female C57BL/6 mice using Hooke kits. Animals were scored for clinical signs of the disease according to a 10-point EAE scoring system. On 21st and 35th days after immunization, mice (n = 4/group) were deeply anesthetized, and the spinal cords were removed. Inflammatory cell infiltration and LCN2 expression in spinal cord were assessed by hematoxylin and eosin staining, immuno-histochemistry, and real-time PCR methods. Results: MS14 significantly ameliorated EAE symptoms and decreased lymphocyte infiltration into the spinal cord (P<0.05). Our data also revealed that LCN2 expression was significantly down-regulated in acute and chronic phases of EAE both at protein and gene levels after MS14 treatment (P<0.05). Conclusion: The results demonstrated that MS14 regulatory effect on EAE is accompanied by LCN2 down-regulation after treatment with the herb; however, more studies are required for clarifying the other involved mechanisms.

Abstract
Effective treatment of ovarian cancer depends upon the early detection of the malignancy. Here, we report on the development of a new nanostructured immunosensor for early detection of cancer antigen 125 (CA-125). A gold electrode was modified with mercaptopropionic acid (MPA), and then consecutively conjugated with silica coated gold nanoparticles (AuNP@SiO2), CdSe quantum dots (QDs) and anti-CA-125 monoclonal antibody (mAb). The engineered MPA|AuNP@SiO2|QD|mAb immunosensor was characterised using transmission electron microscopy (TEM), atomic force microscopy (AFM), cyclic voltammetry (CV) and electrochemical impedance spectroscopy (EIS). Successive conjugation of AuNP@SiO2, CdSe QD and anti-CA-125 mAb onto the gold electrode resulted in sensitive detection of CA-125 with a limit of detection (LOD) of 0.0016 U mL(-1) and a linear detection range (LDR) of 0-0.1 U mL(-1). Based on the high sensitivity and specificity of the immunosensor, we propose this highly stable and reproducible biosensor for the early detection of CA-125.

Abstract
BACKGROUND Cryopreservation of mammalian ovaries has been reported with different levels of success. Cryopreservation of ovarian tissue may be a potential alternative for treatment of infertility and many attempts have been done to improve the efficiency of ovarian cryopreservation. The objective of the present study was to compare the direct cover vitrification (DCV) with ethylene glycol (EG), dimethyl sulfoxide (DMSO) and EG plus DMSO. METHODS Eighty five mice were sacrificed by cervical dislocation and their ovaries were cryopreserved in the presence of 5% EG or DMSO alone or as mixture, 10% EG or DMSO alone or as mixture and a group with ascending concentrations of cryoprotectants. After toxicity testing and vitrification warming, the ovaries were fixed for histological and ultrastructural studies. In addition, the viability of mechanically isolated follicles was studied by trypan blue staining. All data were compared by ANOVA (p<0.05). RESULTS Ovarian tissues frozen in EG plus DMSO in ascending concentrations retained a higher percentage of morphologically normal and or viable follicles than tissues frozen in 10 M EG plus DMSO or in either concentration of EG and DMSO alone (p<0.001). Ultrastructural analysis of ovarian tissues frozen in ascending concentrations of EG plus DMSO showed that these follicles were well preserved and it was very similar to the control group. CONCLUSION Cryopreservation of ovarian tissue in EG plus DMSO is the most effective method for preserving the structural integrity of follicles within the ovary.

Abstract
The number of older people who are suffering from memory impairment is increasing among populations throughout the world. Alzheimer's disease (AD) affects about 5% of people over 65 years old. The hippocampus, a brain area critical for learning and memory, is especially vulnerable to damage in the early stages of AD. Emerging evidence suggests that loss of neurons and synapses are correlated with dementia in this devastating disease. Therefore, neurogenesis and synaptogenesis in adulthood could serve as a preventive as well as a therapeutic target for AD. This study investigated the effect of Rosa damascena extract on neurogenesis and synaptogenesis in an animal model of AD. Molecular, cellular, and behavioral experiments revealed that this treatment could induce neurogenesis and synaptic plasticity and improve memory in AD. Our study suggests that R. damascena is a promising treatment for mild memory impairments and AD.

Abstract
The aim of this study was to determine the resistance pattern and the type of resistance genes of vancomycin-resistant Enterococcus faecalis from Gharamalek wastewater treatment plant in Tabriz, Iran. Following filtering of sewage samples, approximately 300 colonies grew on specific media, of which 53 were randomly selected and purified using 0.45 microm membranes. The membranes were placed on culture media containing antibiotics to isolate the vancomycin-resistant Enterococcus. Biochemical tests, antibiogram and determining minimum inhibitory concentration of antibiotics with E-test including vancomycin were performed. Polymerase Chain Reaction (PCR) was carried out to determine the type of resistance genes. All tested samples were found to be E. faecalis. Antimicrobial susceptibility tests indicated multidrug resistance in the samples, with 98% of them highly resistant to vancomycin. The highest frequency was of vanA (96%), followed by vanB (4%); vanC was not seen among the tested samples. The results confirmed that the risk of exposure to antibiotic-resistant pathogens from the evaluated urban wastewater is considerable.
