Abstract
Objectives During aging, cerebral structures undergo changes due to oxidative stress. The consumption of some plants seems to improve neurological health. For example, rosemary extract (RE) which is widely used as a flavoring food has anti-inflammatory and anti-oxidant activities. Therefore, we aimed to study the effect of RE on the changes related to the aging process in the prefrontal cortex (PFC). Materials and Methods Twenty-four male Wistar rats including young and old were purchased. Each group was divided into two subgroups: vehicle and rosemary (old vehicle (OV), old rosemary (OR), young vehicle (YV), and young rosemary (YR) groups). Then, we examined the number of intact neurons, myelin base protein (MBP), white matter (WM), levels of malondialdehyde (MDA), and glutathione peroxidase (GPx) in the PFC. Results The results showed that in the old vehicle rats compared to the young group without treatment, except for the MDA level (which increased), other variables significantly decreased (P≤0.05). Additionally, RE consumption demonstrated a significant elevation of WMA, MBP intensity, number of intact neurons, and GPx activity level, while MDA levels significantly reduced in the treated old rats compared to the old vehicle group (P≤0.05). However, there was no significant difference between the OR and YV groups (P≥0.05). Conclusion Overall, it seems that RE can protect and improve aging damages in the PFC due to its anti-oxidant properties. So, the use of RE can be a suitable strategy to prevent aging complications in the brain.

Abstract
OBJECTIVE Multiple sclerosis (MS) is known as a nerve tissue disorder, which causes demyelination of central nervous system (CNS) fibers. Cell-based treatment is a novel strategy for the treatment of demyelinating diseases such as MS. Adipose-derived stem cells (ADSCs) have neuroprotective and neuroregenerative effects and pregnenolone as a neurosteroid has remarkable roles in neurogenesis. We intend to examine the impact of intraventricular transplantation of human ADSCs and systemic injection of pregnenolone on the remyelination of a rat model cuprizone-induced demyelination. MATERIALS AND METHODS This experimental study was performed on 36 male Wistar rats that received a regular diet and a cuprizone diet for 3 weeks for M.S. induction. Through lipoaspirate surgery, human-ADSCs (hADSCs) were obtained from a patient. Six groups of rats (n=6): healthy, MS, sham, pregnenolone injection, ADSCs transplantation, and pregnenolone injection/ADSCs transplantation were included in this study. For assessment of remyelination, transmission electron microscopy (TEM), immunohistochemistry staining, real-time reverse transcription-polymerase chain reaction (RT-PCR), and enzyme-linked immunosorbent assay (ELISA) were performed. RESULTS TEM outcomes revealed an increase in the thickness of the fibers myelin in the treatment groups (P<0.05). We also observed a significant upregulation of MBP, PDGFR-α, and MOG after treatment with hADSCs and pregnenolone compared to other study groups (P<0.001). These results were confirmed by immunostaining analysis. Moreover, there was no significant difference between the ADSCs/pregnenolone group and the control group regarding the level of MBP, A2B5, and MOG proteins in ELISA. CONCLUSION Our data implied that the remyelination and cell recovery were more improved by intraventricular ADSCs transplantation and pregnenolone injection after inducing a rat model of MS.

Abstract
Peripheral nerve regeneration is a complicated phenomenon. Thyroid hormones are known as critical regulators in the nervous system development. The Schwann cells have the regenerative potency in the peripheral nervous system. In this study, the human adipose-derived stem cells were assessed in vitro, for transdifferentiation potency into Shwann-like cells (SLCs) as a candidate source for clinical cell therapy, under the treatment of triiodothyronine (T3) hormone, and compared with the untreated cells. The cell viability rate, myelination and neurotrophic factors expression of SLCs were evaluated two weeks post- induction by MTT assay, immunocytochemistry and real-time RT-PCR techniques, respectively. The obtained results revealed a significant decrease in SLCs viability, compared to the adipose-derived stem cells (P < 0.001). Immunocytochemistry technique was applied to detect SLCs markers, such as S100β, GFAP and myelin basic proteins (MBP) in the presence and absence of T3 treatment. The results indicated that administering T3 can significantly increase the differentiation and myelination potency of SLCs (P < 0.01). The findings of real-time RT-PCR technique indicated that the expression of Schwann cells markers, MBP, brain-derived neurotrophic factor and glial cell-derived neurotrophic factor were upregulated significantly with T3 hormone administration in comparison with the untreated cells (P < 0.05). The SLCs were able to express the neurotrophic factors and myelination related genes in the presence of T3 hormone. Furthermore, T3 administration improved myelination potency of adipose-derived stem cells, in vitro. Further in vivo experiments are necessary to confirm the advantages of using a combination of autologous SLCs and T3 hormone for peripheral nerve injury recovery.

Abstract
Background Fibrin as an extracellular matrix feature like biocompatibility, creates a favorable environment for proliferation and migration of cells and it can act as a reservoir for storage and release of growth factors in tissue engineering. Methods In this study, the inner surface of electrospun poly (lactic-co-glycolic acid) (PLGA) nanofibrous conduit was biofunctionalized with laminin containing brain derived neurotrophic factor (BDNF) and gold nanoparticles in chitosan nanoparticle. The rats were randomly divided into five groups, including autograft group as the positive control, PLGA conduit coated by laminin and filled with DMEM/F12, PLGA conduit coated by laminin and filled with rat-adipose derived stem cells (r-ADSCs), PLGA conduit coated by laminin containing gold-chitosan nanoparticles (AuNPs-CNPs), BDNF-chitosan nanoparticles (BDNF-CNPs) and filled with r-ADSCs or filled with r-ADSCs suspended in fibrin matrix, and they were implanted into a 10 mm rat sciatic nerve gap. Eventually, axonal regeneration and functional recovery were assessed after 12 weeks. Results After 3 months post-surgery period, the results showed that in the PLGA conduit filled with r-ADSCs without fibrin matrix group, positive effects were obtained as compared to other implanted groups by increasing the sciatic functional index significantly (p < 0.05). In addition, the diameter nerve fibers had a significant difference mean in the PLGA conduit coated by laminin and conduit filled with r-ADSCs in fibrin matrix groups relative to the autograft group (p < 0.001). However, G-ratio and amplitude (AMP) results showed that fibrin matrix might have beneficial effects on nerve regeneration but, immunohistochemistry and real-time RT-PCR outcomes indicated that the implanted conduit which filled with r-ADSCs, with or without BDNF-CNPs and AuNPs-CNPs had significantly higher expression of S100 and MBP markers than other conduit implanted groups (p < 0.05). Conclusions It seems, in this study differential effects of fibrin matrix, could be interfered it with other factors thereby and further studies are required to determine the distinctive effects of fibrin matrix combination with other exogenous factors in peripheral nerve regeneration.

Abstract
Implantation of a nerve guidance conduit (NGC) carrying neuroprotective factors is promising for repairing peripheral nerve injury. Here, we developed a novel strategy for repairing peripheral nerve injury by gold nanoparticles (AuNPs) and brain-derived neurotrophic factor (BDNF)-encapsulated chitosan in laminin-coated nanofiber of Poly(l-lactide-co-glycolide) (PLGA) conduit and transplantation of rat adipose-derived stem cells (r-ADSCs) suspended in alginate. Then, the beneficial effect of AuNPs, BDNF, and r-ADSCs on nerve regeneration was evaluated in rat sciatic nerve transection model. In vivo experiments showed that the combination of AuNPs- and BDNF-encapsulated chitosan nanoparticles in laminin-coated nanofiber of PLGA conduit with r-ADSCs could synergistically facilitate nerve regeneration. Furthermore, the in vivo histology, immunohistochemistry, and behavioral results demonstrated that the AuNPs- and BDNF-encapsulated chitosan nanoparticles in NGC could significantly reinforce the repair performance of r-ADSCs, which may also contribute to the therapeutic outcome of the AuNPs, BDNF, and r-ADSCs strategies. In this study, we found that the combination of AuNPs and BDNF releases in NGC with r-ADSCs may represent a new potential strategy for peripheral nerve regeneration.

Abstract
Background Alzheimer's disease (AD) is one of the most common neurodegenerative diseases in the older population and characterized by progressive memory and cognitive impairment. Cyperus rotundus, a traditional medicinal herb, has analgesic, sedative, and anti-inflammatory effects and also used to increase memory in Islamic traditional medicine. This study was designed to consider the effects of C. rotundus extract on memory impairment and neurogenesis in the Beta-Amyloid rats' model. Materials and Methods Forty-two male Wistar rats were randomly divided into six groups (n = 7) for the evaluation of baseline training performance in the Morris water maze test. Then, amyloid-beta (Aβ1-42) was injected in animal hippocampal CA1 bilaterally in four groups. The first probe trial was performed 21 days after Aβ injection. Then, 250, 500, and 750 mg/kg of C. rotundus extract were administered to three Aβ-injected groups for 1 month; after that, the second probe trial was performed, and rats were sacrificed after 28 days of the second probe trial. The neurogenesis was detected in the hippocampus, by immunohistochemical staining. Results This study showed that spatial memory increased in the behavioral test in AD treated group with C. rotundus extract, compared with the AD group (P = 0.02). Immunohistochemical staining revealed that neuronal differentiation has been occurred in the hippocampus in the AD-treated group with C. rotundus extract compared with the AD group (P = 0.01). Conclusions This study showed that C. rotundus extract, repaired spatial memory impairment in the Aβ rats, through increased neurogenesis in the hippocampus, which could be related to the flavonoid components in the extract.

Abstract
IL-10 and interferon-gamma (IFN-γ) are the important anti and pro-inflammatory cytokines, respectively, which may participate in the cardiovascular disease pathogenesis. Additionally, environmental factors, such as the X-ray, can modulate cytokine expression. Due to the fact that X-ray is used during angiography, hence, angiography may alter expression of the cytokines. OBJECTIVE Accordingly, this project was aimed to assess IL-10 and IFN-γ serum levels within cardiovascular patients (with and without vessel stenosis) versus healthy controls and also the effects of angiography on the serum levels of the cytokines. MATERIAL AND METHODS This study was performed on the 80 participants, including twenty cases in each group (healthy controls and cardiovascular patients without vessel stenosis, stenosis of 1 vessel and stenosis of more than 1 vessel) to evaluate IL-10 and IFN-γ serum levels using ELISA technique. The IL-10 and IFN-γ serum levels also compared within group 2, 3 and 4 before and after angiography to explore the effects of the technique on the IL-10 and IFN-γ serum levels. RESULTS IL-10, but not IFN-γ, serum levels were higher in the healthy controls than all cardiovascular patients. IL-10 and IFN-γ serum levels were not altered after angiography and also were not differ in the smoker versus non- smoker and opium consuming versus non-opium consuming participants. CONCLUSION Due to the results it may be concluded that IL-10 can be considered as a plausible inhibitor of cardio- vascular diseases independent of angiography duration and X-ray, however, IFN-γ has no effects in the Iranian patients suffering from cardiovascular diseases.

Abstract
Adipose-derived stem cells (ASCs) have neuroprotective effects, and their repair ability has been approved in neurodegenerative studies. Pregnenolone as a neurosteroid plays significant roles in neurogenesis. We aimed to consider the effect of ADSCs and pregnenolone injection on the multiple sclerosis (MS) model created by cuprizone. Male Wistar rats (n = 36) were fed with an ordinary diet or a diet with cuprizone (0.6%) for 3 weeks. H-ADSCs were taken from patients with lipoaspirate surgery. The rats were divided into six groups (n = 6): healthy, MS, sham, pregnenolone injection, ADSCs injection, pregnenolone and ADSCs injection. Behavioral test, histological examination and TEM were conducted. The specific markers for myelin and cell differentiation were assessed using immunohistochemistry staining. Additionally, the measure of MBP and MOG gene expression and the amount of related proteins were determined using real-time RT-PCR and ELISA techniques, respectively. Histologic results showed that induced demyelination in corpus callosum fibers. TEM revealed an increased thickness of myelin in fibers in the treated groups (P < 0.05). Injection of hADSC and pregnenolone significantly increased the expression levels of MBP and MOG (P < 0.001). The mean percentage of MOG and MBP markers were significantly increased in the treated groups compared to MS and sham groups (P < 0.05). Moreover, the OD level of MBP and MOG proteins showed that their values in the ADSCs/pregnenolone group were close to those of the control group without a significant difference. Our data indicated the remyelination potency and cell differentiation can improve with ADSCs and pregnenolone treatments in the multiple sclerosis model which created by cuprizone in rats.

Abstract
Alzheimer's disease (AD) is a progressive neurodegenerative disturbance leading to memory deficit, cognitive decline, and behavioral disturbance. Deposition of Amyloid beta plaques, neurofibrillary tangle and mitochondrial impairment are common neuropathological signs in AD. In this study, the effect of standardized Cyperus rotundus(C. rotundus) extract in three different doses of 250, 500, and 750 mg/kg on memory, neurogenesis and mitochondrial mass in the beta amyloid rat model was assessed. For this purpose, 42 male Wistar rats were randomly divided into six groups (n = 7) to evaluate baseline training performance in Morris water maze test. Amyloid beta (Aβ) was injected in animal hippocampal CA1 bilaterally in four groups. After 21 days, a decrease was observed in spending time in target quadrant in the first probe trial in Aβ injected groups. Following that, 250, 500, and 750 mg/kg of C. rotundus extracts were administered to three out of four groups for a period of one month. BrdU (Bromodeoxyuridine) was intraperitoneally injected in all groups on the last 7 days of treatment. Then, 28 days after the last BrdU injection, the second probe trial was run, and rats were sacrificed. The neurogenesis and mitochondrial distribution were detected in hippocampus, by immunohistochemical staining. At last, it was observed that C. rotundus, almost recovered memory impairment, in addition to increasing in mitochondrial mass in CA1 and neurogenesis in dentate gyruse in the beta-amyloid rat model of Alzheimer's disease.

Abstract
Testicular cancer is one of the most common malignancy in young men, chemotherapy induced damage in cancerous cells as well as healthy tissue, and we decided to investigate recovery effect of zinc (Zn) on chemotherapy-induced complications in rat chromatin integrity and testicular histomorphometry. The male rats (n = 40) were treated with BEP at appropriate dose levels of BEP (0.75, 7.5, and 1.5 mg/kg) for 9 weeks, with or without Zn; testicular histology, sperm DNA methylation, ubiquitination, DNA fragmentation and protamination were further assessed through immunofluorescence. BEP treatment significantly increased ubiquitination, and DNA fragmentation, considerably reducing global DNA methylation and protamination (P < 0.001), resulting in degenerative changes in testicular structure. Zn restored normal DNA methylation, protamination and structure of male gonads, maintained spermatogonial stem cells, and significantly reduced the mean percentage of ubiquitination and sperm DNA fragmentation as compared with BEP group (P < 0.001). We found that supplementation of Zn following chemotherapy can improve chromatin integrity, testicular organization and spermatogenesis.

Abstract
Peripheral nerve damage is a common clinical complication of traumatic injury occurring after accident, tumorous outgrowth, or surgical side effects. Although the new methods and biomaterials have been improved recently, regeneration of peripheral nerve gaps is still a challenge. These injuries affect the quality of life of the patients negatively. In the recent years, many efforts have been made to develop innovative nerve tissue engineering approaches aiming to improve peripheral nerve treatment following nerve injuries. Herein, we will not only outline what we know about the peripheral nerve regeneration but also offer our insight regarding the types of nerve conduits, their fabrication process, and factors associated with conduits as well as types of animal and nerve models for evaluating conduit function. Finally, nerve regeneration in a rat sciatic nerve injury model by nerve conduits has been considered, and the main aspects that may affect the preclinical outcome have been discussed.

Abstract
Retinal degenerative diseases lead to blindness due to poorly regenerative potential of the retina. Recently, cell therapy is more considered for degenerative diseases. Autologous mesenchymal stem cells derived from adipose tissue are a suitable source for this purpose. Therefore, we conducted a stepwise efficient method to differentiate human adipose-derived stem cells (hADSCs) into retinal precursor-like cells in vitro. We compared two differentiation protocols, monolayer and hanging drop cultures. Through the defined medium and 3D hanging drop culture method, we could achieve up to 75% retinal precursor gene expression profile (PAX6, RAX, CHX10, and CRX) from hADSCs. By imitation of in vivo development, for direct conversion of stem cells into retinal cells, the suppression of the BMP, Nodal, and Wnt signaling pathways was carried out by using three small molecules. The hADSCs were primarily differentiated into anterior neuroectodermal cells by expression of OTX2, SIX3, and Β-TUB III and then the differentiated cells were propelled into the retinal cells. According to our data from real-time PCR, RT-PCR, immunocytochemistry, and functional assay, it seems that the hanging drop method improved retinal precursor differentiation yield which these precursor-like cells respond to glutamate neurotransmitter. Regarding the easy accessibility and immunosuppressive properties of hADSCs and more efficient hanging drop method, this study may be useful for future autologous cell therapy of retinal degenerative disorders.

Abstract
The constant release of neurotrophic factors through a nanomaterial-based delivery system can be an important strategy in medical and pharmaceutical fields for nerve tissue engineering. The present study was aimed at encapsulating NGF and AuNPs in chitosan nanoparticles (NGF-CNPs and AuNPs-CSNPs) and its evaluation on the differentiation potential of human adipose-derived stem cells (h-ADSCs) to Schwann-like cells. The NGF-CNPs were prepared by ionotropic gelation method with tripolyphosphate (TPP) as a crosslinker. After synthesis and characterization of nanoparticles, NGF encapsulation efficiency and release profile were observed by Bradford assay. Next, the effects of NGF-CSNPs and AuNPs-CSNPs on h-ADSCs survival were assessed through MTT assay. Also, the efficacy of Schwann-like cells differentiation was assessed by immunocytochemistry and real-time RT-PCR for S100β and MBP markers. NGF encapsulation efficiency was found about 85% and controlled and sustained release of NGF was observed during 7 days in vitro (74.63 ± 2.07%). The findings revealed that these nanoparticles are cytocompatible. The immunocytochemical analysis indicated that NGF-CSNPs and AuNPs-CSNPs could significantly increase the differentiated rate and myelinogenic potential of Schwann-like cells (p < 0.05). Besides, the expression level of GFAP, S100β, and MBP demonstrated significant upregulation in NGF-CSNPs and AuNPs-CSNPs groups compared to the control group (p < 0.05). Hence, it can be proposed that NGF-CNPs and AuNPs-CSNPs are capable of controlled release with improving the ability of h-ADSCs differentiation to Schwann-like cells. Also, the results show the potential future application of this differentiation in nerve tissue regeneration.

Abstract
Objective The incidence rate of testicular cancer among young males is high. Co-administration of bleomycin, etoposide
and cisplatin (BEP) has increased survival rate of patients with testicular cancer. Although BEP is one of the most effective
treatment for testicular cancer, but it severely affects the reproductive system that ultimately leads to infertility. In addition to its
antioxidant activity, zinc has an important role in progression of spermiogenesis. This study aimed to evaluate the effect of zinc
on sperm parameters, chromatin condensation and testicular structure after BEP treatment.
Materials and Methods In this experimental study, 40 male rats were divided into 4 groups (control, BEP, BEP+ zinc and
zinc) and examined for 2 spermatogenesis periods (i.e. 18 weeks). The rats in BEP and BEP+ zinc group were treated with
BEP at appropriate doses (0.75, 7.5, and 1.5 mg/kg) for three cycles of three weeks. Zinc at a dose of 10 mg/kg/day was
administered to BEP+ zinc and zinc groups. After 18 weeks, we assessed sperm parameters, and excessive histone in sperm
chromatin using aniline blue staining, as well as testicular structure and germ line cells using periodic acid-Schiff staining.
Results After BEP treatment, significant decreases were observed in normal sperm morphology, motility, and
concentration, as well as alterations in rat sperm chromatin condensation and testicular tissue (P<0.001). Furthermore,
after zinc consumption for 9 weeks, we observed significant improvements of sperm parameters and chromatin
condensation as well as a significant retrieval of spermatogonia, leydig cells and tubular architecture (P<0.05).
Conclusion Zinc administration after chemotherapy with BEP in testicular cancer might be potentially useful in declining the
off target consequence associated with oxidative stress.

Abstract
Background: Reconstruction of nervous system is a great challenge in the therapeutic medical field. Nerve tissue engineering is a novel method to regenerate nervous system in human health care. Tissue engineering has introduced novel approaches to promote and guide peripheral nerve regeneration using submicron and nanoscale fibrous scaffolds. Materials and Methods: In this study, 9 wt% poly(3-hydroxybutyrate) (PHB) solutions with two different ratios of chitosan (CTS) (15%, and 20%) were mixed in trifluoroacetic acid as a cosolvent. Thereafter, random and aligned PHB/CTS scaffolds were fabricated by electrospinning method in an appropriate condition. Results: Average diameters for aligned PHB, PHB/CTS 85:15 and PHB/CTS 80:20 were obtained as 675 nm, 740.3 nm, and 870.74 nm, which was lesser than random fibers. The solution components entity authenticity was approved by Fourier transform infrared. The addition of CTS decreased both water droplet contact angle from 124.79° to 43.14° in random and 110.87° to 33.49° in aligned PHB/CTS fibrous scaffold. Moreover, alignment of fibers causes tremendous increase in hydrophilicity of fibrous PHB/CTS substrate. Tensile strength increased from 6.41 MPa for random to 8.73 MPa for aligned PHB/CTS 85:15. Conclusions: Our results indicated that aligned PHB/CTS 85:15 nanofibers are the desired scaffold than the random PHB/CTS nanofibers for application in nerve tissue regeneration.

Abstract
Objective This study aimed to isolate and culture SADS cells, investigate their neurogenic capacity and evaluate their
application for nerve tissue engineering.
Materials and Methods In this experimental study, SADS cells were isolated from human adipose tissue. After 7-day
treatment of SADS cells with insulin, indomethacin and isobutylmethylxanthine, neurogenic differentiation of SADS cells was
investigated. During this study, Poly (ε-caprolactone) (PCL) and PCL/gelatin nanofibrous scaffolds were fabricated using
electrospinning and subsequently nanofibrous scaffolds were coated with platelet-rich plasma (PRP). SADS cells were also
seeded on nanofibrous scaffolds and neurogentic differentiation of these cells on nanofibers was also evaluated. Effect of PRP
on proliferation and differentiation of SADS cells on scaffolds was also studied.
Results Our results showed that after 7-day treatment of SADS cells with insulin, indomethacin and
isobutylmethylxanthine, SADS cells expressed markers characteristic of neural cells such as nestin and neuron specific
nuclear protein (NEUN) (as early neuronal markers) as well as microtubule-associated protein 2 (MAP2) and neuronal
microtubule-associated (TAU) (as mature neuronal markers) while mature astrocyte maker (GFAP) was not expressed.
MTT assay and SEM results showed that incorporation of gelatin and PRP into the structure of nanofibrous scaffolds
has a significant positive influence on the bioactivity of scaffolds. Our results also showed neurogentic differentiation
of SADS cells on scaffolds.
Conclusion Our results demonstrated that SADS cells have potential to differentiate into early and mature progenitor
neurons, in vitro. PCL/gelatin/PRP was found to be a promising substrate for proliferation of SADS cells and differentiation
of these cells into neural cells which make these scaffolds a candidate for further in vivo experiments and suggest their
application for nerve tissue engineering.

Abstract
Objective The presence of neurotrophic factors is critical for regeneration of neural lesions. Here, we transplanted
combination of neurotrophic factor secreting cells (NTF-SCs) and human adipose derived stem cells (hADSCs) into a
lysolecithin model of multiple sclerosis (MS) and determined the myelinization efficiency of these cells.
Materials and Methods In this experimental study, 50 adult rats were randomly divided into five groups: control,
lysolecithin, vehicle, hADSCs transplantation and NTF-SCs/ hADSCs co-transplantation group. Focal demyelization
was induced by lysolecithin injection into the spinal cord. In order to assess motor functions, all rats were scored weekly
with a standard experimental autoimmune encephalomyelitis scoring scale before and after cell transplantation. Four
weeks after cell transplantation, the extent of demyelination and remyelination were examined with Luxol Fast Blue
(LFB) staining. Also, immunofluorescence method was used for evaluation of oligodendrocyte differentiation markers
including; myelin basic protein (MBP) and Olig2 in the lesion area.
Results Histological study show somewhat remyelinzation in cell transplantation groups related to others. In addition,
the immunofluorescence results indicated that the MBP and Olig2 positive labeled cells were significantly higher in
co-cell transplantation group than hADSCs group (P<0.05). Also, outcome of motor functional test showed significant
improvement function in cell transplantation groups, as compared to the others (P<0.01).
Conclusion Our results indicated that the remyelinization process in co-cell transplantation group was better than other
groups. Thus, NTF-SCs/ hADSCs transplantation can be proper candidate for cell based therapy in neurodegenerative
diseases, such as MS.

Abstract
Interference with bacterial adhesion is a new means to prevent or treat bacterial infections. In this experimental study we evaluated the immunogenic properties of a chimeric protein composed of PilQ and disulphide turn region of PilA from Pseudomonas aeruginosa in mice as an anti-adhesion based vaccine. First of all, a chimeric bivalent protein composed of PilQ and PilA was constructed and following subcutaneous immunization with merely the purified protein or in its admixed form with alum, the immunogenicity of the chimeric antigen was assessed in BALB/c mice. Then, the characteristics of the developed antibodies were studied by ELISA. Furthermore, the immunoreactivity of the purified recombinant protein was confirmed by immunoblotting. Alum as a common adjuvant boosted immunogenicity of the construct, resulting significantly greater anti-pili IgG titre. Mice antibody response consisted of IgG1, IgG2a, IgG2b and IgG3 subtypes with predominance of IgG1 subclass. The developed antibodies were capable to inhibit motility of PAO1 strain. In conclusion, our primary results revealed that the designed recombinant protein is a protective construct and may be used as a potential candidate for prophylactic purposes against P. aeruginosa infection. SIGNIFICANCE AND IMPACT OF THE STUDY In this study we examined the potential of integrated PilQ/PilA (QA) antigen as a vaccine candidate against Pseudomonas aeruginosa. Nowadays, anti-adhesion based vaccines are considered as new means to prevent or treat bacterial infections. Our study revealed that chimeric protein PilQ and disulphide turn region of PilA triggers production of specific antibodies. This humoral immune responses augmented when QA was administered in combination with an adjuvant. The results demonstrated efficacy of the designed recombinant chimeric antigen as an effective candidate in prevention of P. aeruginosa infection.

Abstract
Inspired by in vivo developmental process, several studies were conducted to design a protocol for differentiating of mesenchymal stem cells into neural cells in vitro. Human adipose-derived stem cells (hADSCs) as mesenchymal stem cells are a promising source for this purpose. At current study, we applied a defined neural induction medium by using small molecules for direct differentiation of hADSCs into anterior neuroectodermal cells. Anterior neuroectodermal differentiation of hADSCs was performed by hanging drop and monolayer protocols. At these methods, three small molecules were used to suppress the BMP, Nodal, and Wnt signaling pathways in order to obtain anterior neuroectodermal (eye field) cells from hADSCs. After two and three weeks of induction, the differentiated cells with neural morphology expressed anterior neuroectodermal markers such as OTX2, SIX3, β-TUB III and PAX6. The protein expression of such markers was confirmed by real time, RT-PCR and immunocytochemistry methods According to our data, it seems that the hanging drop method is a proper approach for neuroectodermal induction of hADSCs. Considering wide availability and immunosuppressive properties of hADSCs, these cells may open a way for autologous cell therapy of neurodegenerative disorders.

Abstract
BACKGROUND One of the new methods of scaffold fabrication is a nano-micro hybrid structure in which the properties of the scaffold are improved by introducing nanometer and micrometer structures. This method could be suitable for scaffold designing if some features improve. MATERIALS AND METHODS In this study, electrospun nanofibers of 9% weight solution of poly (3-hydroxybutyrate) (P3HB) and a 15% weight of chitosan by trifluoroacetic acid were coated on both the surface of a silk knitted substrate in the optimum condition to improve the mechanical properties of scaffolds for cartilage tissue engineering application. These hybrid nano-micro fibrous scaffolds were characterized by structural and mechanical evaluation methods. RESULTS Scanning electron microscopy values and porosity analysis showed that average diameter of nanofibers was 584.94 nm in electrospinning part and general porosity was more than 80%. Fourier transform infrared spectroscopy results indicated the presence of all elements without pollution. The tensile test also stated that by electrospinning, as well as adding chitosan, both maximum strength and maximum elongation increased to 187 N and 10 mm. It means that the microfibrous part of scaffold could affect mechanical properties of nano part of the hybrid scaffold, significantly. CONCLUSIONS It could be concluded that P3HB-chitosan/silk hybrid scaffolds can be a good candidate for cartilage tissue engineering.

Abstract
Multiple sclerosis (MS) is a chronic inflammatory disease characterized by central nervous system (CNS) lesions that can lead to severe physical or cognitive disability as well as neurological defects. Although the etiology and pathogenesis of MS remains unclear, the present documents illustrate that the cause of MS is multifactorial and include genetic predisposition together with environmental factors such as exposure to infectious agents, vitamin deficiencies, and smoking. These agents are able to trigger a cascade of events in the immune system which lead to neuronal cell death accompanied by nerve demyelination and neuronal dysfunction. Conventional therapies for MS are based on the use of anti-inflammatory and immunomodulatory drugs, but these treatments are not able to stop the destruction of nerve tissue. Thus, other strategies such as stem cell transplantation have been proposed for the treatment of MS. Overall, it is important that neurologists be aware of current information regarding the pathogenesis, etiology, diagnostic criteria, and treatment of MS. Thus, this issue has been discussed according to recent available information.

Abstract
There is wide interest in application of adult stem cells due to easy to obtain with a minimal patient discomfort, capable of producing cell numbers in large quantities and their immunocompatible properties without restriction by ethical concerns. Among these stem cells, multipotent mesenchymal stem cells (MSCs) from human adipose tissue are considered as an ideal source for various regenerative medicine. In spite of mesodermal origin of human adipose-derived stem cells (hADSCs), these cells have differentiation potential toward mesodermal and non-mesodermal lineages. Up to now, several studies have shown that hADSCs can undergo transdifferentiation and produce cells outside of their lineage, especially into neural cells when they are transferred to a specific cell environment. The purpose of this literature review is to provide an overview of the existing state of knowledge of the differentiation potential of hADSCs, specifically their ability to give rise to neuronal cells. The following review discusses different protocols considered for differentiation of hADSCs to neural cells, the neural markers that are used in each procedure and possible mechanisms that are involved in this differentiation.

Abstract
Background: Diabetes in pregnancy is a common metabolic disorder associated with various adverse outcomes in the offspring including impairments in attention and memory and alterations in social behavior. Glial cells are proven to have a critical role in normal function of neurons, and alteration in their activity could contribute to disturbance in the brain function. The aim of this study was to investigate the effect of maternal diabetes on hippocampal mRNA expression and distribution pattern of glial fibrillary acidic protein (GFAP) immunoreactive glial cells in the dentate gyrus (DG) of rat neonate at postnatal day 14 (P14). Materials and Methods: Wistar female rats were randomly allocated in control, diabetic, and insulin-treated diabetic groups. Diabetes was induced by injection of streptozotocin from 4 weeks before gestation until parturition. After delivery, the male offspring was euthanized at P14. Results: Our results showed a significant higher level of hippocampal GFAP expression and an increase in the mean number of GFAP positive cells in the DG of diabetic group offspring (P < 0.05). We also found an insignificant up-regulation in the expression of GFAP and the mean number of positive cells in the insulin-treated diabetic group neonates as compared to control group (P > 0.05). Conclusion: The present study revealed that diabetes during pregnancy strongly increased the glial cells production in the developing rat hippocampus.

Abstract
Tissue engineering techniques particularly using electrospun scaffolds have been intensively used in recent years for the development of small diameter vascular grafts. However, the development of a completely successful scaffold that fulfills multiple requirements to guarantee complete vascular regeneration remains challenging. In this study, a hydrophilic and compliant polyurethane namely Tecophilic (TP) blended with gelatin (gel) at a weight ratio of 70:30 (TP(70)/gel(30)) was electrospun to fabricate a tubular composite scaffold with biomechanical properties closely simulating those of native blood vessels. Hydrophilic properties of the composite scaffold induced non-thrombogenicity while the incorporation of gelatin molecules within the scaffold greatly improved the capacity of the scaffold to serve as an adhesive substrate for vascular smooth muscle cells (SMCs), in comparison to pure TP. Preservation of the contractile phenotype of SMCs seeded on electrospun TP(70)/gel(30) was yet another promising feature of this scaffold. The nanostructured TP(70)/gel(30) demonstrated potential feasibility toward functioning as a vascular graft.

Abstract
Background: Diabetes mellitus is associated with cognitive deficits in humans and animals. These deficits are paralleled by neurophysiological and structural changes in brain. In diabetic animals, impairments of spatial learning, memory, and cognition occur in association with distinct changes in hippocampus, a key brain area for many forms of learning and memory and are particularly sensitive to changes in glucose homeostasis. However, the multifactorial pathogenesis of diabetic encephalopathy is not yet completely understood. Apoptosis plays a crucial role in diabetes-induce neuronal loss in hippocampus. Methods: The effects of diabetes on hippocampus and cognitive/behavioral dysfunctions in experimental models of diabetes are reviewed, with a focus on the negative impact on increased neuronal apoptosis and related cellular and molecular mechanisms. Results: Of all articles that were assessed, most of the experimental studies clearly showed that diabetes causes neuronal apoptosis in hippocampus through multiple mechanisms, including oxidative stress, inhibition of caspases, disturbance in expression of apoptosis regulator genes, as well as deficits in mitochondrial function. The balance between pro-apoptotic and anti-apoptotic signaling may determine the neuronal apoptotic outcome in vitro and in vivo models of experimental diabetes. Conclusions: Dissecting out the mechanisms responsible for diabetes-related changes in the hippocampal cell apoptosis helps improve treatment of impaired cognitive and memory functions in diabetic individuals.

Abstract
BACKGROUND Some antidepressant drugs can promote neuronal cell proliferation in vitro as well as hippocampal neurogenesis in human and animal models. Furthermore, adipose tissue is an available source of adult stem cells with the ability to differentiate in to multiple lineages. Therefore, human Adipose-Derived Stem Cells (hAD-SCs) may be a suitable source for regenerative medical applications. Since there is no evidence for the effect of Paroxetine as the most commonly prescribed antidepressant drug for neurogenic potential of hADSCs, an attempt was made to determine the effect of Paroxetine on proliferation and neural differentiation of hADSCs. METHODS ADSCs were isolated from human abdominal fat. These cells differentiated to neuron-like cells and were treated with Paroxetine. 3-[4, 5-dimethylthiazol-2-yl]-2, 5-diphenyl tetrazolium bromide (MTT) assay and immunofluorescence technique were used for assessment of cell proliferation and neurogenic differentiation potential of induced cells, respectively. RESULTS MTT assay analysis showed that Paroxetine significantly increased the proliferation rate of induced hADSCs (p<0.05), while immunofluorescent staining indicated that Paroxetine treatment during neurogenic differentiation could enhance the mean percentage of Nestin and MAP2 (Microtubule-associated protein-2) positive cells but the mean percentage of GFAP (Glial acidic fibrillary protein) positive cells significantly decreased relative to control group (p<0.05). CONCLUSION Our results provide evidence that Paroxetine can promote proliferation and differentiation rate during neurogenic differentiation of hADSCs. Moreover, Paroxetine can reduce gliogenesis of induced hADSCs during neurogenic differentiation.

Abstract
BACKGROUND Different studies have been done to obtain sufficient number of neural cells for treatment of neurodegenerative diseases, spinal cord, and traumatic brain injury because neural stem cells are limited in central nerves system. Recently, several studies have shown that adipose-derived stem cells (ADSCs) are the appropriate source of multipotent stem cells. Furthermore, these cells are found in large quantities. The aim of this study was an assessment of proliferation and potential of neurogenic differentiation of ADSCs with passing time. MATERIALS AND METHODS Neurosphere formation was used for neural induction in isolated human ADSCs (hADSCs). The rate of proliferation was determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay and potential of neural differentiation of induced hADSCs was evaluated by immunocytochemical and real-time reverse transcription polymerase chain reaction analysis after 10 and 14 days post-induction. RESULTS The rate of proliferation of induced hADSCs increased after 14 days while the expression of nestin, glial fibrillary acidic protein, and microtubule-associated protein 2 was decreased with passing time during neurogenic differentiation. CONCLUSION These findings showed that the proliferation of induced cells increased with passing time, but in early neurogenic differentiation of hADSCs, neural expression was higher than late of differentiation. Thus, using of induced cells in early differentiation may be suggested for in vivo application.

Abstract
Objective In this study, nano-biocomposite composed of poly (lactide-co-glycolide)
(PLGA) and chitosan (CS) were electrospun through a single nozzle by dispersing the CS
nano-powders in PLGA solution. The cellular behavior of human adipose derived stem
cells (h-ADSCs) on random and aligned scaffolds was then evaluated.
Materials and Methods In this experimental study, the PLGA/CS scaffolds were prepared
at the different ratios of 90/10, 80/20, and 70/30 (w/w) %. Morphology, cell adhesion and prolif-
eration rate of h-ADSCs on the scaffolds were assessed using scanning electron microscope
(SEM), 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyl tetrazolium bromide (MTT) assay and trypan
blue staining respectively.
Results H-ADSCs seeded on the matrices indicated that the PLGA/CS composite matrix
with aligned nanofibres and higher content of CS nano-powders gave significantly better
performance than others in terms of cell adhesion and proliferation rate (P<0.05).
Conclusion We found that CS enhanced cell adhesion and proliferation rate, and
aligned nanofibers guided cell growth along the longitudinal axis of the nanofibers,
which would provide a beneficial approach for tissue engineering.

Abstract
OBJECTIVES Estrogen is a sexual hormone that has prominent effects on reproductive and non-reproductive tissues. The aim of this study is to evaluate the effects of estrogen on the proliferation and neural differentiation of human adipose derived stem cells (ADSCs) during neurogenic differentiation. MATERIALS AND METHODS Isolated human ADSCs were trans-differentiated in neural induction medium containing neurobasal medium, N2 and B27 with or without 17β-estradiol (E2) treatment. Proliferation rate and neural differentiation of human ADSCs were assessed using MTT assay, immunostaining and real time RT- PCR analysis, respectively. RESULTS Analysis of data show that estradiol treatment can significantly increase proliferation rate of differentiated cells (P<0.05). Immunocytochemical and real time RT-PCR analysis revealed that the expression of precursor and mature neuronal markers (nestin and MAP2) was significantly higher in the E2 treated cell cultures when compared to the untreated cell cultures (P<0.05). CONCLUSION According to our findings, estrogen can promote proliferation and neuronal differentiation of human ADSCs.

Abstract
OBJECTIVE Due to the restricted potential of neural stem cells for regeneration of central nervous system (CNS) after injury, providing an alternative source for neural stem cells is essential. Adipose derived stem cells (ADSCs) are multipotent cells with properties suitable for tissue engineering. In addition, alginate hydrogel is a biocompatible polysaccharide polymer that has been used to encapsulate many types of cells. The aim of this study was to assess the proliferation rate and level of expression of neural markers; NESTIN, glial fibrillary acidic protein (GFAP) and microtubule-associated protein 2 (MAP2) in encapsulated human ADSCs (hADSCs) 10 and14 days after neural induction. MATERIALS AND METHODS In this experimental study, ADSCs isolated from human were cultured in neural induction media and seeded into alginate hydrogel. The rate of proliferation and differentiation of encapsulated cells were evaluated by 3-[4, 5-dimethylthiazol-2-yl]-2, 5-diphenyl tetrazolium bromide (MTT) assay, immunocytoflourescent and realtime reverse transcriptase polymerase chain reaction (RT-PCR) analyzes 10 and 14 days after induction. RESULTS The rate of proliferation of encapsulated cells was not significantly changed with time passage. The expression of NESTIN and GFAP significantly decreased on day 14 relative to day 10 (P<0.001) but MAP2 expression was increased. CONCLUSION Alginate hydrogel can promote the neural differentiation of encapsulated hADSCs with time passage.

Abstract
Neurotrophins are small molecules of polypeptides, which include nerve growth factor (NGF) family, glial cell line–derived neurotrophic factor (GDNF) family ligands, and neuropoietic cytokines. These factors have an important role in neural regeneration, remyelination, and regulating the development of the peripheral and central nervous systems (PNS and CNS, respectively) by intracellular signaling through specific receptors. It has been suggested that the pathogenesis of human neurodegenerative disorders may be due to an alteration in the neurotrophic factors and their receptors. The use of neurotrophic factors as therapeutic agents is a novel strategy for restoring and maintaining neuronal function during neurodegenerative disorders such as multiple sclerosis. Innate and adaptive immune responses contribute to pathology of neurodegenerative disorders. Furthermore, autoimmune and mesenchymal stem cells, by the release of neurotrophic factors, have the ability to protect neuronal population and can efficiently suppress the formation of new lesions. So, these cells may be an alternative source for delivering neurotrophic factors into the CNS.

Abstract
The transdifferentiation of human adipose-derived stem cells (ADSCs) into Schwann-like cells on biocomposite scaffolds may be a critical issue in nerve regeneration medicine. In this study, tissue-engineered scaffold with chitosan (CS) nanopowders and poly(lactide-co-glycolide) (PLGA) was investigated for its potential Schwann cells (SCs) transdifferentiation. The differentiation of human ADSCs into S-like cells was induced with different CS content and direction of nanofibers on PLGA/CS scaffolds. Cell morphology and proliferation of differentiated cells were investigated by scanning electron microscopy and 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide assay respectively. For assessment efficiency of transdifferentiation, the expression of SC markers (glial fibrillary acidic protein and S100), and myelinogenic marker (myelin basic protein) was investigated in different nanochitosan content and direction of nanofibers scaffolds, using immunocytochemistry technique. The nanochitosan can significantly promote cell proliferation of differentiated cells (p < 0.05). The mean percentage of S-like cells on greater CS content nanofibers scaffold was significantly higher than others (p < 0.05). In addition, the align orientation of nanofibers in scaffolds guided the differentiation of ADSCs toward myelinating S-like cells on the constructs. Overall, we found that high CS content and aligned-orientation of nanofibers in biocomposite scaffold (70/30A) can promote differentiation and myelinogenic capacity of S-like cells induced from human ADSCs.

Abstract
BACKGROUND Male factor has been considered as a 50% of infertility causes. One of the reasons for poor semen quality is oxidative stress. Saffron and vitamin E as antioxidant agent can be involved in free radical scavenging and improvement of semen quality. MATERIALS AND METHODS We divided 30 adult male Wistar rats into saffron (n = 10), vitamin E (n = 10) and control (n = 10) groups randomly. Saffron (100 mg/kg/day), vitamin E (100 mg/kg/day), and distilled water (0.5 ml/day) were fed by gavage to the animals for 60 consecutive days in aforementioned groups. After cervical dislocation, both testes and left epididymis of each animal were removed and the cauda epididymal spermatozoa were aspirated for analysis of sperm parameters. Sperm membrane integrity was assessed by hypo-osmotic swelling test (HOST). In different groups, seminiferous tubule histological assessments were done after Hematoxylin -Eosin staining. RESULTS The mean percentage of HOST positive sperm was increased in vitamin E and saffron groups as compared to control group. As we can see there was a significant difference among control and experimental groups (P < 0.001); also a significant difference was obtained between vitamin E and saffron groups (P = 0.002). The evaluation of seminiferous tubules has shown no significant differences among groups. CONCLUSIONS The present data suggest that saffron had superior antioxidant properties which can improve sperm parameters and membrane integrity so it can lead to develop fertility potential.

Abstract
Background: Antidepressant drugs are commonly employed for anxiety and mood disorders. Sertraline is extensively used as antidepressant in clinic. In addition, adipose tissue represents an abundant and accessible source of adult stem cells with the ability to differentiate in to multiple lineages. Therefore, human adipose-derived stem cells (hADSCs) may be useful for autologous transplantation. Materials and Methods: In the present study, we assessed the effect of antidepressant drug Sertraline on the proliferation and neurogenic differentiation of hADSCs using MTT assay and immunofluorescence technique respectively. Results: MTT assay analysis showed that 0.5 μM Sertraline significantly increased the proliferation rate of hADSCs induced cells (P < 0.05), while immunofluorescent staining indicated that Sertraline treatment during neurogenic differentiation could be decreased the percentage of glial fibrillary acidic protein and Nestin-positive cells, but did not significantly effect on the percentage of MAP2 positive cells. Conclusion: Overall, our data show that Sertraline can be promoting proliferation rate during neurogenic differentiation of hADSCs after 6 days post-induction, while Sertraline inhibits gliogenesis of induced hADSCs.

Abstract
BACKGROUND In recent years, adipose tissue, due to the stem cells contained within, has found a new special place in laboratory and clinical applications. These adipose-derived stem cells (ADSCs) have the same characteristics of bone marrow mesenchymal stem cells (BMSCs). Although bone marrow (BM) is not easily accessible and its procurements may be painful, most patients possess excess fat which can be obtained by less invasive methods; this makes adipose tissue ubiquitous, available and an ideal large-scale source for research on clinical applications. METHODS BMSCs and ADSCs were harvested from three healthy human and were characterized using flow-cytometry. After they were treated for neurosphere formation using basic fibroblast growth factor, epidermal growth factor, B 27; terminal differentiation was performed. In this study, we used immunocytochemistry, real time-polymerase chain reaction and western blotting techniques for detection and comparison of Nestin, microtubule-associated protein-2 (MAP-2) and glial fibrillary acidic protein (GFAP) markers in human ADSCs and BMSCs. RESULTS Under appropriate conditions ADSCs can differentiate into neuron-like cells and express neural markers the same as BMSCs, also the expression of GFAP marker in differentiated cells derived from ADSCs was significantly lower than the cells derived from BMSCs (P < 0.05). While the expression of MAP-2 marker in both groups was the same. CONCLUSIONS However, due to its advantages and according to our results based on the expression levels of GFAP and MAP-2, adipose tissue rather than BM could represent a more appropriate stem cell source for investigating the application of these cells in understanding the pathophysiology and in treatment of neurodegenerative disorders.

Abstract
BACKGROUND Currently, relation between reactive oxygen species (ROS) ROS concentration and semen quality was indicated. Saffron has traditionally been not only considered as a food additive but also as a medicinal herb, which has a good antioxidant properties. OBJECTIVE The aim of this study was to evaluate the protection potency of saffron and vitamin E on sperm chromatin integrity. MATERIALS AND METHODS Thirty adult male Wistar rats divided equally into saffron (100 mg/kg), vitamin E (100 mg/kg) and control (0.5cc distilled water /day) groups. After 60 days, cauda epididymis dissected and sperm cells were used for analysis of sperm chromatin packaging by chromomycin A3 (CMA3) staining, and sperm chromatin susceptibility to acid denaturation by acridine orange (AO) staining. RESULTS The mean percentage of CMA3 positive sperm was significantly decreased in saffron and vitamin E groups relative to control group (p<0.001). Moreover, the AO staining results showed that the mean percentage of sperm with DNA damage was significantly decreased in saffron and vitamin E groups as compared with control group (p<0.001). CONCLUSION Our results purposed that saffron can protect sperm against DNA damage and chromatin anomalies.

Abstract
The ability of mature smooth muscle cells (SMCs) to modulate their phenotype in response to environmental cues is a critical issue related to vascular diseases. A tissue engineered vascular graft shall promote the contractile phenotype of vascular SMCs. To this aim, Tecophilic/gelatin (TP/gel) was electrospun at different weight ratios of TP/gelatin (100:0, 70:30, 50:50, 30:70), leading to differences in biochemical and mechanical properties of the nanofibers which in turn influenced the phenotype of SMCs. Results indicated that both the substrate with higher ligand density and lower stiffness could enhance SMC contractility and reduce cell proliferation. However, observing the highest SMCs contractility on electrospun TP(70)/gel(30) among the composite scaffolds demonstrated stiffness as the most critical parameter. Due to conflicting effects of softness versus minor fraction of gelatin (reduced ligand density) within TP(70)/gel(30) fibers, a relatively high proliferation of SMCs was still observed on TP(70)/gel(30) scaffold. The surface of TP(70)/gel(30) scaffold was further modified through physical adsorption of gelatin molecules so as to increase the ligand density on its surface, whereby a functional vascular construct that promotes the contractile behavior of SMCs with low cell proliferation was developed.
