Introduction & Objective: The amniotic membrane (AM) has distinctive characteristics and potentials that make it a proper biomaterial for tissue engineering. There are varieties of methods for preserving the AM. In this study, the AM was preserved using different methods. The effect of preservation on tissue composition and physical and mechanical properties was compared between preserved and fresh samples of the AM.
Materials & Methods: The human AM was preserved after being detached from the placenta. It was preserved using either cryopreservation methods (in temperature of -80 ºC, for 6 months) or lyophilization. The preserved AM was histologically assessed using light and electronic microscopy. Mechanical tolerance of the preserved AM was also measured using uniaxial tension test, suture retention test and thickness calculation.
Results: This study showed that the value of Fmax and elongation at break in the cryopreserved and lyophilaized AM was smaller than the same value in the fresh AM samples. All of the samples had same tolerance in suture retention test, although lyophilaized samples of the AM were thinner than other types of the samples. Tissue composition (histological properties) regarding epithelial cells and tissue layers of the AM were not the same in different samples.
Conclusion: Cryopreservation and lyophilization as two preservation methods of the AM, can affect the tissue composition and physical and mechanical features of the AM. Thus the preservation method for the AM can be chosen regarding the final usage of the AM as a biomaterial.

Background and objective: Hearing loss and tinnitus are two auditory effects of hearing system damage due to occupational noise exposure. These factors can have non-auditory effects by themselves and impact on brain cognitive performance. In our study, the effect of occupational noise-induced hearing loss and tinnitus on cognition and auditory-verbal memory was investigated.
Materials and methods: Our study was done on 42 male workers aged 40 to 56 years in three groups of workers with 1) hearing loss, 2) hearing loss and tinnitus and 3) normal hearing. Workers in two first groups had a long history of working in environments with excessive noise, and third group was matched control workers with normal hearing. Hearing impaired persons had symmetrical moderate falling sensory-neural hearing loss in the both ears. For all subjects, Mini-Mental State Examination and Rey Auditory-Verbal Learning Tests were performed in identical conditions.
Results: Normal hearing group had higher scores in all stages of the Rey Auditory-Verbal Learning test than two other groups and their means differences in three A1, Sum and Recognition stages were significant (p≤0.034). Similar finding was observed in the Mini-Mental Examination test too (p≤0.025).
Conclusion: Our study revealed effect of noise induced hearing loss and tinnitus due to prolonged exposure to noise over the limit on general cognition and auditory-verbal memory. Given the preventable nature of auditory and non-auditory effects of occupational noise, administration and control of hearing conservation programs and training of workers can be the suitable and proposed solution.

Background: Smoking can decrease adiponectin serum and increase insulin resistance index. The purpose of present study was to examine the effect of one session of exhaustive aerobic exercise on levels of adiponectin serum and insulin resistance index in smoker men.
Materials and methods: A semi-experimental design was used. The target population consisted of smoker students of the Hakim Sabzevari University, from whom twelve smoker male students volunteered and were randomly divided into three situations; control, exhaustive aerobic exercise at 70-75% intensity of maximal heart rate, and exhaustive aerobic exercise at 90-95% intensity of maximal heart rate, in a crossover design.Two situations of aerobic exhaustive exercise programs involved running on treadmill with intensities of 70-75% and 90-95% of maximum heart rate of the subjects. During this period, the control group did not perform any physical activity. To calculate changes in plasma volume and measurement of adiponectin, glucose, insulin and lipid profile indices blood samples were collected before and immediately after performing of aerobic exercises. Data were analyzed using one way analysis of variance (ANOVA).
Results: After the correction of results with respect to plasma volume changes, no significant differences in serum of adiponectin levels (P=0.825) and insulin resistance index (P=0.756) were determined between the control and experimental situations. Furthermore, no significant difference was observed among the three situations in the glucose (P=0.633), insulin (P=0.768), low density lipoprotein (P=0.075), high density lipoprotein (P=0.131), total cholesterol (P=0.559), and serum triglyceride (P=0.641).
Conclusion: One session of exhaustive aerobic exercise with two different intensities has no effect on levels of serum adiponectin and insulin resistance index in smoker men. However, to achieve more conclusive results, further investigation is warranted.

Objective: In The last two decades, nursing homes for elderly have expanded tremendously. Client satisfaction is one of the most important indicators of service quality delivered by institutes and organizations. This study was carried out to measure client satisfaction in the private nursing homes of Golestan, Mazandaran, Semnan and Northern Khorasan Provinces in 2012.
Methods: In this cross-sectional study, 89 participants from all 14 nursing homes located in the pre-mentioned provinces who met the inclusion criteria including age 60 years or older, ability to communicate, Abbreviated Mental Test scores of 6 or higher, and at least 6 months stay duration were recruited by the method of census and interviewed. Data was gathered using the questionnaire of Assessing Elderly Residents' Satisfaction of the Delivered Services in Nursing Homes. In order to analyze data, statistical parametric t-test, ANOVA, Mann-Whitney, Kruskal-Wallis test, Spearman correlation coefficient and SPSS software (version 17), were used.
Results: Mean scores showed that satisfaction with the physical care (3.55) and physical environment (3.77) were higher than of satisfaction with psychological care (3.00) and social care (3.26). The mean score of overall satisfaction with the services was 3.40 and indicative of satisfaction in the levels of moderate to good.

Introduction: The insulin-like growth factor naturally exists in the Central Nervous System (CNS) and plays a significant role in cellular multiplication and differentiation during growth and maturation of the brain. These factors are expressed with their bond proteins and their receptors in the damaged areas of the brain. This indicates the role of IGFs systems in the brain damage.
Objective: Molecular simulation is a direct computational method for studying the structural changes of a wide spectrum of physical and biological issues. Computationally, experimental force fields have various forms in simulation of folding insulin-like growth factor.
Materials and Methods: In this study, the transfer temperature for IGF1 was modulated. The system was balanced and was studied and analyzed through dynamic molecular method within 500 Pico seconds.
Results: Studying the changes occurred in the potential energy of the three force fields showed that Amber force field is better than MM+ and OPLS force field and also MD simulation, at least in this model, is more effective than MC and LD methods.
Conclusion: Low temperatures make the structure more stable while high temperatures are on the contrary.

Introduction: It is well recognized that gender and race differences play a role in pain sensitivity, pain perception, response to analgesic drug and prevalence of certain chronic pain disorders. In this study investigated gender and strain-related differences in the effect of food deprivation on formalin induced nociceptive behaviors in rats.
Methods: This study was done in Qazvin University of Medical Sciences 8 groups of rats (220-300gr). Groups 1 and 2: Effect formalin-induced nociceptive behaviours in male and female Sprague-Dawley rats. Groups 3 and 4: Effect formalin-induced nociceptive behaviours in male and female Wistar rats. Groups 5 and 6: Effect of food deprivation on formalin-induced nociceptive behaviours in male and female Sprague-Dawley rats. Groups 7 and 8: Effect of food deprivation on formalin-induced nociceptive behaviours in male and female Wistar rats. Food was withdrawn 48 h (short-term food deprivation) prior to performing the formalin test, but water continued to be available ad libitum. The formalin (50 μL, 2%) was injected into hind plantar paw. Immediately after the formalin injection, pain behaviors recorded for 90 minutes.
Results: There is significant difference between male and female control Sprague-Dawley rats during phase 2B. Although interphase in male rats is more than female ones, but the phase 2B in female rats is more than male ones and phase 2 finished with delay in Sprague-Dawley race. There are no significant differences between male and female control Wistar rats during formalin test. Following 48-h food deprivation, male and female rats exhibited enhanced nociceptive behaviors in response to formalin injection during phase 1, the interphase, phase 2. In contrast, 48 h food deprivation had significant effect on formalin-evoked nociceptive behaviors in phase 2B for male Wistar and in interphase and phase 2B for female rats.
Conclusion: The present study demonstrates the existence of gender and strain-related differences in rats in the development and maintenance of inflammatory hyperalgesia. Also, these differences observed following food deprivation.

Background and purpose: Morphine addiction and morphine withdrawal syndrome are of main problems in human societies. In the present study, effect of nicotine on the strength of physical and psychological dependency, produced by single and repeated doses of morphine, was investigated.
Material and method: Male wistar rats were dependent to morphine with single and repeated dose protocols. In the single dose protocol, rats received only one dose of morphine and 24h later were given Naloxone. In the repeated dose protocol, rats received incremental doses of morphine for 7 days and 24h after the last dose (8th day) were given Naloxone. In the single dose protocol, rats were given one dose of nicotine 30 min before Naloxone. However in the repeated doses they received nicotine 15 min before morphine for 4 days from 4th day to 7th day. 5 min after Naloxone each rat′s behavior was captured for 30 min. then physical and psychological signs of withdrawal syndrome were recorded.
Results: Results showed that injection of repeated and even single dose of morphine can produce dependency. Nicotine consumption attenuated strength of withdrawal syndrome signs, specially increasing weight excrement and total withdrawal score in single dose protocol and weight excrement increasing, weight decreasing, place aversion, and total withdrawal score in repeated dose treatment.
Conclusion: Based on our data, even a single dose of morphine can produce dependency in rats. Conversely, Nicotine consumption attenuates strength of withdrawal syndrome signs.

Depression is a main complication in the developed and in developing countries. Studies showed that depression not only is a emotional disease but also affect the body. Immune system disordering is an important complication following depression. Studies showed that depression can induce immunological chronic inflammation, hence, lead to accelerate depression. Several molecules including JAK/STAT pathways and Toll like receptors, AIMII and NLRs play important roles in inducing chronic inflammation. It seems that the mentioned molecules can induce inflammation via cytokine production in depressed patients. Therefore, evaluation of cytokine patterns and cytokines producing pathways in depressed patients can help scientists to find the pathogenesis of depression. Thus, the aim of this review article was to collect recent information regarding cytokine patterns as well as the related molecules in inflammation in depression.
