Sleep loss and the brain vulnerability to neurodegeneration: behavioral, biochemical and neurohistopathological observations in a rat model

Background: Experimentally-induced total sleep deprivation (TSD) and chronic partial sleep restriction (CPSR) leads to the emergence of cognitive impairments. This is hypothesized to result from a consequent neuroinflammation which may also hasten the neurodegenerative processes. Neuroinflammatory markers such as tumor necrosis factor-alpha (TNFα) are thought to be potential culprits in SD-induced neurodegeneration. Methods: The effect of TSD and CPSR on memory and anxiety-related behaviors (using the Elevated Plus-Maze testretest protocol) and serum level of brain derived neurotrophic factor (BDNF) and corticosterone were assessed in male Wistar rats subjected to the modified disk-over-water (DOW)apparatus. In addition, an immunohistochemical (IHC) study was done to possibly detect the amyloid-beta (Aβ) and hyper-phosphorylated tau protein (HPτ) deposition in the dentate gyrus (DG) of the examined rats’ hippocampi. Histomorphology and neuronal numerical density assessments were done at the same level across control and experimental animals. We also studied the above parameters in rats after intraperitoneal injection of the TNFα neutralizing antibody, infliximab (IFX). Results: Rats subjected to TSD and CPSR which did not receive IFX, showed a more pronounced impairment of memory, elevated serum corticosterone and decreased BDNF levels. CPSR rats which underwent delayed brain excision following behavioral testing, showed deposition of the HPτ and revealed the least numerical density in the hippocampal DG neurons. Meanwhile, IHC study revealed no Aβ deposition in the hippocampal DG of all examined rats. Interestingly, treatment with IFX, abrogated sleep restriction-induced cognitive decline, biochemical changes and the immunohistopathology in the hippocampal DG. Conclusions: Taken together, our findings indicated that CPSR (the SD model mimicking shift work) induces not only cognitive and biochemical changes, but also pathology in the hippocampal DG. This is possibly via activation of the inflammatory mechanisms in part through TNFα-dependent pathways

A computer-based selective visual attention test for first-grade school children: Design, development and psychometric properties

Background: Visual attention is known as a critical base for learning. The purpose of the present study was to design, develop and evaluate the test-retest and internal consistency reliability as well as face, content and convergent validity of the computer- based selective visual attention test (SeVAT) for healthy first-grade school children. Methods: In the first phase of this study, the computer-based SeVAT was developed in two versions of original and parallel. Ten experts in occupational therapy helped to measure the content validity using the CVR and CVI methods. Face validity was measured through opinions collected from 10 first-grade children. The convergent validity of the test was examined using the Spearman correlation between the SeVAT and Stroop test. In addition, test-retest reliability was determined by measuring the intra-class correlation (ICC) between the original and parallel versions of the SeVAT in a single session. The internal consistency was calculated by Cronbach's alpha coefficients. Sixty first grade children (30 girls/30boys) participated in this study. Results: The developed test was found to have good content and face validity. The SeVAT showed an excellent test-retest reliability (ICC= 0.778, p<0.001) and internal consistency (Cronbach's Alpha of original and parallel tests were 0.857 and 0.831, respectively). SeVAT and Stroop test demonstrated a positive correlation upon the convergent validity testing. Conclusion: Our results suggested an acceptable reliability and validity for the computer-based SeVAT in the assessment of selective attention in children. Further research may warrant the differential validity of such a test in other age groups and neuro-cognitively disordered populations

Psychometric properties of the Persian version of the Fatigue Impact Scale (FIS-P) in patients with Multiple Sclerosis

Objectives: This study was designed to evaluate the psychometric features of the Persian version of the Fatigue Impact Scale (FIS-P) tool when used in Iranian MS patients. Methods: 140 MS patients and the equivalent number of healthy controls completed the following assessments: FIS-P, Fatigue Severity Scale (FSS), SF-36 questionnaire and the Mini-Mental State Examination (MMSE). Results: A significant inverse correlation between FIS and the quality of life (SF-36 assessment tool), as well as a positive and significant correlation with the FSS were noted. The Intraclass Correlation Coefficient (ICC) values for the inter-rater reliability for the physical, cognitive, and social sections and the whole questionnaire were 0.89, 0.86, 0.95 and 0.98, respectively. The FIS Persian version was shown to possess a high reliability (with a Cronbach's alpha of 0.953). Likewise, the ICC values for the testretest reliability were 0.86, 0.87, 0.92 and 0.93 for the physical, cognitive, social subscales and the whole questionnaire, respectively. This suggested a high reliability for the FIS-P. Discussion: With a proper validity and reliability, the Persian-version of FIS retains the capability for being used in the assessment of fatigue and evaluation of the treatment and rehabilitation effects on fatigue-related symptoms among Persian-speaking patients with MS

RESEARCH AND REVIEWS: JOURNAL OF MICROBIOLOGY AND BIOTECHNOLOGY Biosynthesis and Characterization of Selenium Nanoparticles Produced by Terrestrial Actinomycete Streptomyces microflavus Strain FSHJ31

ABSTRACT During last decades, study on the development of eco-friendly processes for the production of selenium nanoparticles (Se NPs) have received much attention due to hazardous effects of chemical compounds used for nanoparticle preparation. The present study was designed to screen actinomycete strains able to produce Se NPs. Among isolated bacterial strains, a terrestrial actinomycete strain which was tolerant to Se 4+ ions (200 µg/ml of) was launched as Se NPs producer. Morphological and biochemical characteristics as well as 16S rDNA gene analysis of the selected strain introduced it as Streptomyces microflavus strain FSHJ31. The biologically synthesized Se NPs was then purified using n-Octyl alcohol/water extraction system and characterized by UV-vis spectroscopy, transmission electron microscopy (TEM), energy dispersive X-ray (EDX) and Fourier transform infrared spectroscopy (FTIR) techniques. Analysis of the particle size distribution pattern of biogenic Se NPs via laser light scattering method demonstrated the size range of 28-123 nm for Se NPs with the 48 nm NPs being the most frequent particles

Invasive candidiasis in intensive care unit; consensus statement from an Iranian panel of experts, July 2013

Invasive candidiasis (IC) is associated with high mortality in intensive care unit (ICU) patients. Timely diagnosis of this potentially fatal condition remains a challenge; on the other hand, the criteria for initiating empirical antifungal therapy in critically ill patients are not well defined in different patient population and ICU settings. Alongside the international guidelines, reaching regional and local consensus on diagnosis and management of IC in ICU setting is essential. This report summarizes our present status of IC management in ICU, considered by a group of Iranian experts in the fields of intensive care and infectious diseases. A round table of 17 experts was held to review the available data and discuss the optimal treatment strategies for IC in critical care setting. Comparative published data on the management of IC were analytically reviewed and the commonly asked questions about the management of IC in ICU were isolated. These questions were interactively discussed by the panel and audience responses were taken to consolidate point-to-point agreement with the panel arriving at consensus in many instances. The responses indicated that patient's risk stratification, clinical discretion, fungal diagnostic techniques and the empirical therapy for IC are likely to save more patients. Treatment options were recommended to be based on the disease severity, prior azole exposure, and the presence of suspected azoleresistant Candida species. This report was reviewed, edited and discussed by all participants to include further evidence-based insights. The panel expects such endorsed recommendations to be soon formulated for implementation across the country. © 2014 The Author(s)

Sleep in Elite Athletes and Nutritional Interventions to Enhance Sleep

Sleep has numerous important physiological and cognitive functions that may be particularly important to elite athletes. Recent evidence, as well as anecdotal information, suggests that athletes may experience a reduced quality and/or quantity of sleep. Sleep deprivation can have significant effects on athletic performance, especially submaximal, prolonged exercise. Compromised sleep may also influence learning, memory, cognition, pain perception, immunity and inflammation. Furthermore, changes in glucose metabolism and neuroendocrine function as a result of chronic, partial sleep deprivation may result in alterations in carbohydrate metabolism, appetite, food intake and protein synthesis. These factors can ultimately have a negative influence on an athlete’s nutritional, metabolic and endocrine status and hence potentially reduce athletic performance. Research has identified a number of neurotransmitters associated with the sleep–wake cycle. These include serotonin, gamma-aminobutyric acid, orexin, melanin-concentrating hormone, cholinergic, galanin, noradrenaline, and histamine. Therefore, nutritional interventions that may act on these neurotransmitters in the brain may also influence sleep. Carbohydrate, tryptophan, valerian, melatonin and other nutritional interventions have been investigated as possible sleep inducers and represent promising potential interventions. In this review, the factors influencing sleep quality and quantity in athletic populations are examined and the potential impact of nutritional interventions is considered. While there is some research investigating the effects of nutritional interventions on sleep, future research may highlight the importance of nutritional and dietary interventions to enhance sleep

Where Neuroscience and Art Embrace The Neuroaesthetics

Neuroscience has recently contributed a lot to the understanding of aesthetic experience features. Science, art and creativity are not really distinctively different entities. The parallelism seen between the properties of art and organizational principals of the brain has been highlighted through neuroaesthetic studies. Aesthetic as a subjective experience has comprehensively been studies through neuro-scientific, psychological, sociologic and cultural standpoints. This is a controversial topic in cognitive neuroscience, meanwhile seemingly varied results of the conducted researches in this field may be conceptualized in a framework linking aesthetics to neuroscience of affective visual processing, reward circuitries and the nature of decision making. Approaching the question of art-brain parallelism, is along side with elucidating the relation between perception and aesthetic experience,and the features of aesthetic judgment and reward. Moreover, other factors such as cultural underpinnings undoubtedly come into play. In this review we used expert opinions and literary notions to present a report on how neuroscience has so far elaborated on different features of the aesthetic phenomenon hoping to probe areas of neuroaeshetic research which can potentially assess our cultural interface with the aesthetics and cognitive neuroscience

Vancomycin-Resistant Staphylococcus aureus isolates among hospitalized patients; a tertiary medical care center experience from Southern Iran

Background and Objective: Bacterial resistance to different types of antibiotics has been globally emerging over recent years. The present study was carried out to investigate the rate of vancomycin-resistant Staphylococcus aureus (VRSA) at a tertiary medical care center in Kerman, Iran. Materials and Methods: In this cross-sectional study, 250 samples with positive culture for coagulase-positive S. aureus, taken from the suspected infectious sites of patients admitted to different medical and surgical wards at Bahonar hospital from 2009 to 2011, were studied. Results: 9.2% of S. aureus isolates were found to be vancomycin-resistant. There was no significant difference in the rate of resistance between males and females (8 vs. 12.9%, respectively). Though the rate of resistance was shown to be marginally higher in post-surgical compared to medical ward patients, the difference was statistically insignificant (p = 0.8). Across the wards, general surgery housed the largest number of patients with VRSA (20%). Conclusion: The emergence of VRSA isolates has perhaps not received a great deal of attention so far. It appears that the increasing use of vancomycin in non-complicated infections may contribute to the emergence of S. aureus isolates which turn to be vancomycin-resistant

Repetitive Arm Movements During Sleep: A Polysomnographic Assessment

Sleep-related movement disorders should be differentiated from parasomnias, sleep-associated&nbsp;behavioral disorders, and epilepsy. Polysomnography (PSG) is the gold standard in evaluating&nbsp;such disorders. Periodic leg movement disorder during sleep (PLMS), hypnic jerks, bruxism,&nbsp;rhythmic movement disorder, restless legs syndrome, and nocturnal leg cramps have broadly&nbsp;been discussed in the literature. However, periodic arm movement disorder in sleep (PAMS) is&nbsp;a less-appreciated entity perhaps because arm surface electromyography is not an integral part&nbsp;of the standard polysomnography. Results from our PSG study in a case suspected for PAMS&nbsp;prompted us to herewith discuss this problem
