Abstract
Objectives Metformin (Met) and liraglutide (Lira) have been approved to treat type 2 diabetes mellitus and have cardioprotective effects. Materials and Methods Human umbilical vein endothelial cells (HUVECs) were incubated with Met, Lira, or their combination in this study. Results Results showed that the synergistic inhibitory effect of the two drugs on HUVECs proliferation was significant (75%) after 48 hr drug exposure. In addition, either Lira or Met alone had a marked tendency to inhibit the migration of HUVECs (42% and 39%). Almost a complete inhibition (97%) was demonstrated in combinational use after 48 hr treatment. After combining these two drugs, the apoptosis rate raised to 68%, which was a significant approval of synergistic apoptosis induction of Met and Lira. The combinational group indicated a substantial increase in VEGF, PDGF, and MMP-9 at 24 hr compared with the control. Conclusion This study showed that combination therapy with Lira and Met could effectively reduce cell proliferation, induce apoptosis, and inhibit cell migration in the HUVECs. This study provides evidence to support using Met in combination with Lira as a treatment option for patients with type-2 diabetes and cancer.

Abstract
Hydrogel biomaterials have many favorable characteristics including tuneable mechanical behavior, cytocompatibility, optical properties suitable for regeneration and restoration of the damaged cornea tissue. The cornea is a tissue susceptible to various injuries and traumas with a complicated healing cascade, in which conserving its transparency and integrity is critical. Accordingly, the hydrogels' known properties along with the stimulation of nerve and cell regeneration make them ideal scaffold for corneal tissue engineering. Hydrogels have been used extensively in clinical applications for the repair and replacement of diseased organs. The development and optimizing of novel hydrogels to repair/replace corneal injuries have been the main focus of researches within the last decade. This research aims to critically review in vitro, preclinical, as well as clinical trial studies related to corneal wound healing using hydrogels in the past 10 years, as this is considered as an emerging technology for corneal treatment. Several unique modifications of hydrogels with smart behaviors have undergone early phase clinical trials and showed promising outcomes. Financially, this considers a multibillion dollars industry and with huge interest from medical devices as well as pharmaceutical industries with several products may emerge within the next five years.

Abstract
Treatment of non-healing skin wounds infected with extensively drug-resistant (XDR) bacteria remains as a big challenge. To date, different biomaterials have been applied for treatment of post-wound infections, nevertheless their efficacy for treatment of the wounds infected with XDR isolates has not been determined yet. In this study, the potential of the thermo-responsive chitosan (TCTS) hydrogel for protection of full-thickness wounds XDR bacteria isolated from burn patients was evaluated both in vitro and in vivo in a rat model. Antibacterial activity of the TCTS hydrogel against standard strain and clinical isolates of Acinetobacter baumannii, cytobiocompatibility for Hu02 fibroblast cells, degradation rate and swelling ratio were determined in vitro. MTT assay and disk diffusion test indicated no detectable cytotoxicity and antibacterial activity in vitro, respectively. In vivo study showed significant acceleration of wound healing, re-epithelialization, wound closure, and decreased colony count in the TCTS hydrogel group compared with control. This study suggests TCTS hydrogel as an excellent wound dressing for management of the wounds infected with XDR bacteria, and now promises to proceed with clinical investigations.

Abstract
Introduction: Excessive daytime sleepiness is related to significant morbidity and mortality in either the patients or others. Maintenance of Wakefulness Test (MWT) is designed to evaluate the ability to maintenance of wakefulness in standard conditions of the test. Due to the existence of different methods for performing and interpreting the MWT test and the importance of unifying the method of performing and interpreting this test in Iran, the localization of the clinical use guide of the MWT test was considered.
Materials and Methods: Initially, it was studied the available guidelines, and one of them was chosen as the main guideline. Then, to standardize the clinical services provided to patients, according to the conditions and facilities in Iran, the localization of the clinical guideline of MWTtest was performed.
Results: This guideline contained recommendations for implementation and interpretation of MWT. For each recommendation, the level of evidence including “standard”, “guideline” and “option” was specified.
Conclusion: Given the prevalence of drowsiness and its importance in safety, occupational accidents and road accidents and the role of MWT testing in its evaluation, it is hoped that by providing the most cost-effective diagnostic method in this guide, a step will be taken to better allocate health resources in the country.

Abstract
Immunoinformatics is a science that helps to create significant immunological information using bioinformatics softwares and applications. One of the most important applications of immunoinformatics is the prediction of a variety of specific epitopes for B cell recognition and T cell through MHC class I and II molecules. This method reduces costs and time compared to laboratory tests. In this state-of-the-art review, we review about 50 papers to find the latest and most used immunoinformatic tools as well as their applications for predicting the viral, bacterial and tumoral structural and linear epitopes of B and T cells. In the clinic, the main application of prediction of epitopes is for designing peptide-based vaccines. Peptide-based vaccines are a considerably potential alternative to low-cost vaccines that may reduce the risks related to the production of common vaccines.

Abstract
Genetic mutations of the Methyl-CpG-binding protein-2 (MECP2) gene underlie Rett syndrome (RTT). Developmental processes are often considered to be irrelevant in RTT pathogenesis but neuronal activity at birth has not been recorded. We report that the GABA developmental shift at birth is abolished in CA3 pyramidal neurons of Mecp2-/y mice and the glutamatergic/GABAergic postsynaptic currents (PSCs) ratio is increased. Two weeks later, GABA exerts strong excitatory actions, the glutamatergic/GABAergic PSCs ratio is enhanced, hyper-synchronized activity is present and metabotropic long-term depression (LTD) is impacted. One day before delivery, maternal administration of the NKCC1 chloride importer antagonist bumetanide restored these parameters but not respiratory or weight deficits, nor the onset of mortality. Results suggest that birth is a critical period in RTT with important alterations that can be attenuated by bumetanide raising the possibility of early treatment of the disorder.

Abstract
Chitosan as a biopolymer is an attractive vehicle for biomedical applications due to its unique characteristics. In order to improve chitosan's physicochemical features, chemical modification has been carried out to make it more suitable for such approaches. The aim of this study was to prepare and evaluate thiolated chitosan-lauric acid as a new chitosan derivative for biomedical use. Lauric acid was introduced to chitosan via stable amide bond between carboxylic acid group of fatty acid and the amine in the chitosan and thiolation was carried out using thioglycolic acid. Resulted polymers were characterized by FTIR, 1H NMR and TGA. Moreover, cell viability assessment of new derivative was performed using MTT method. FTIR and 1H NMR results showed that both substitution reactions were successfully completed. Furthermore, new synthesized polymer had no significant cytotoxicity against normal gingiva human cells (HGF1-PI 1).These findings confirm that this new derivative can be introduced as a suitable polymer for biomedical purposes such as mucosal drug delivery.

Abstract
We report that the apical dendrites of CA3 hippocampal pyramidal neurons are increased during labor and birth in the valproate model of autism but not in control animals. Using the iDISCO clearing method, we show that hippocampal, especially CA3 region, and neocortical volumes are increased and that the cerebral volume distribution shifts from normal to lognormal in valproate-treated animals. Maternal administration during labor and birth of the NKCC1 chloride transporter antagonist bumetanide, which reduces [Cl-]i levels and attenuates the severity of autism, abolished the neocortical and hippocampal volume changes and reduced the whole-brain volume in valproate-treated animals. These results suggest that the abolition of the oxytocin-mediated excitatory-to-inhibitory shift of GABA actions during labor and birth contributes to the pathogenesis of autism spectrum disorders by stimulating growth during a vulnerable period.

Abstract
The sensory neuropeptide calcitonin gene-related peptide (CGRP) plays a role in primary headaches, and CGRP receptor antagonists are effective in migraine treatment. CGRP is a potent vasodilator, raising the possibility that antagonism of its receptor could have cardiovascular effects. We therefore investigated the effects of the antimigraine CGRP receptor antagonist telcagepant (MK-0974) [N-[(3R,6S)-6-(2,3-difluorophenyl)-2-oxo-1-(2,2,2-trifluoroethyl)azepan-3-yl]-4-(2-oxo-2,3-dihydro-1H-imidazo[4,5-b]pyridine-1-yl)piperidine-1-carboxamide] on human isolated coronary arteries. Arteries with different internal diameters were studied to assess the potential for differential effects across the coronary vascular bed. The concentration-dependent relaxation responses to human alphaCGRP were greater in distal coronary arteries (i.d. 600-1000 microm; E(max) = 83 +/- 7%) than proximal coronary arteries (i.d. 2-3 mm; E(max) = 23 +/- 9%), coronary arteries from explanted hearts (i.d. 3-5 mm; E(max) = 11 +/- 3%), and coronary arterioles (i.d. 200-300 microm; E(max) = 15 +/- 7%). Telcagepant alone did not induce contraction or relaxation of these coronary blood vessels. Pretreatment with telcagepant (10 nM to 1 microM) antagonized alphaCGRP-induced relaxation competitively in distal coronary arteries (pA(2) = 8.43 +/- 0.24) and proximal coronary arteries and coronary arterioles (1 microM telcagepant, giving pK(B) = 7.89 +/- 0.13 and 7.78 +/- 0.16, respectively). alphaCGRP significantly increased cAMP levels in distal, but not proximal, coronary arteries, and this was abolished by pretreatment with telcagepant. Immunohistochemistry revealed the expression and colocalization of the CGRP receptor elements calcitonin-like receptor and receptor activity-modifying protein 1 in the smooth muscle cells in the media layer of human coronary arteries. These findings in vitro support the cardiovascular safety of CGRP receptor antagonists and suggest that telcagepant is unlikely to induce coronary side effects under normal cardiovascular conditions.

Abstract
AlMCM-41 was applied for adsorption of methylene blue (MB) and rhodamine B (RB) in single and binary component systems. In the single component systems, AlMCM-41 represents higher adsorption capacity for MB than RB with the maximal adsorption capacity of 2.08x10(-4) and 8.74x10(-5)mol/g at 25 degrees C for MB and RB, respectively. In the binary component system, MB and RB exhibit competitive adsorption onto the adsorbent. The adsorption is approximately reduced to 94 and 79% of single component adsorption systems for MB and RB (initial concentration of 8x10(-6)M) at 25 degrees C. In single and binary component systems, kinetic and adsorption isotherm studies demonstrate that the data are following pseudo-second-order kinetic model and Langmuir isotherm. Effect of solution pH on the adsorption in single and binary component systems was studied and the results were described by electrostatic interactions.
