N-doped graphene aerogel with a 3D inter-connected network was synthesized using graphene oxide and pyrrole in an aqueous medium with ammonia. Hydrothermal and thermal annealing methods were employed to do it so. The structure and surface properties of the synthesized aerogel were characterized using Fourier Transform Infrared (FTIR) spectroscopy, X-ray Diffraction (XRD), Raman spectroscopy, Field Emission Scanning Electron Microscopy (FE-SEM), XPS, and nitrogen adsorption/desorption measurements. The prepared n-doped aerogel exhibited elevated specific surface area (340 m2/g), hydrophobic nature, and excellent adsorption capacity (210 g/g for crude oil removal). Adsorbent recyclability was also investigated; it is worth noting that after ten subsequent cycles, only just a negligible decrement in adsorption capacity was observed. Furthermore, the effect of salts and temperature on adsorption capacity was studied. Isotherm and kinetic studies were last examined. The conformity of various adsorption models, including Freundlich, Langmuir, Temkin, and Dubinin–Radushkevich (D–R) to the equilibrium data was evaluated among which Langmuir isotherm model gave the best fitting result. The sorption kinetics data were well described by the pseudo-second-order kinetic model. As a consequence, oil spills adsorption using n-doped graphene aerogel is a relatively cost-effective method which can be scaled up, and it could be a promising material for removal of organic contaminants from water.

Family Ismaridae Thomson (Hymenoptera, Diaprioidea), new to fauna of Iran
Zahra RAHMANI,김창준,Mostafa GHAFOURI MOGHADDAM,Ehsan RAKHSHANI 한국곤충학회 2019 Entomological Research Vol.49 No.9
Occurrence of the family Ismaridae Thomson is recorded for the first time from Iran, represented by a single species, Ismarus rugulosus Förster, 1850. A series of diagnostic characters and morphometric ratios for this species is presented, as well as a distribution map throughout the Holarctic region.

Sleep Disorders During Pregnancy and Postpartum: A Systematic Review
Moghadam Zahra Behboodi,Rezaei Elham,Rahmani Azam 대한수면학회 2021 sleep medicine research Vol.12 No.2
This study aimed to asses previous research results about bio-physiological alterations during pregnancy and postpartum, and make clear outlook about prevalence and related factors of sleep disorders during pregnancy and postpartum. In this review, the articles that published from 2000 to 2019 were reviewed. Related articles were searched from databases in English language. After evaluation of inclusion and exclusion criteria, articles were chosen and reviewed based on the University of York strategies. Sleep disorders in present study were classified according to the International Classification of Sleep Disorders-3. The search revealed 4449 articles, after evaluating and assessing qualified articles, finally 56 article selected to review. According to the results of this review, The prevalence of sleep disorders was almost 76%–97% in whole pregnancy. The most common sleep disorders included central disorders of hyper somnolence (waking up in the middle of the night, daytime sleepiness, sleeplessness) or insomnia, sleep-related movement disorders (restless legs syndrome), sleep related breathing disorders (obstructive sleep apnea), and parasomnia. In addition, sleep disorder may continue 3–12 months postpartum (33.2%). Sleep disorders induced by physiological processes (fetal movement, excessive weight gain, male sex of the fetus, and multiparty), health-related risks (metabolism disorders, cardiovascular diseases, and mood disorders), and physical or sexual abuse in childhood. In addition, these disorders could have maternal outcomes that can be greatest trigger to postpartum psychiatric disorders and fetal outcomes that have harmful sequences during childhood (sexual, fertility, emotional, and cognitive problems). Health care providers should evaluate the mothers’ sleep quality because sleep disorder leads to harmful consequences in fetuses and children.

Return to Work and Its Relation to Financial Distress among Iranian Cancer Survivors
Ghasempour, Mostafa,Rahmani, Azad,Davoodi, Arefeh,Sheikhalipour, Zahra,Ziaeei, Jamal Evazie,Abri, Fariba Asian Pacific Journal of Cancer Prevention 2015 Asian Pacific journal of cancer prevention Vol.16 No.6
Background: Return to work after treatment completion is important for both cancer survivors and society. Financial distress is one of the factors that may influence the return to work in cancer survivors. However, this relationship has not been well investigated. This study aimed to determine the rate of return to work and its relation to financial distress among Iranian cancer survivors. Materials and Methods: This descriptive-correlational study was undertaken among 165 cancer survivors who completed their initial treatments and had no signs of active cancer. The Return to Work questionnaire and Financial Distress/Financial Well-Being Scale were used for data collection. Data were analyzed using SPSS statistical software. Results: After initial treatments, 120 cancer survivors (72%) had returned to work, of which 50 patients (42%) had returned to full-time work and 70 (58%) reduced their work hours and returned to part-time work. Cancer survivors also reported high levels of financial distress. In addition, the financial distress was lower among patients who had returned completely to work, in comparison to patients who had quit working for cancer-related reasons (p= 0.001) or returned to work as part-time workers (p=0.001). Conclusions: The findings showed that a high percent of Iranian cancer survivors had not returned to their jobs or considerably reduced working hours after treatment completion. Accordingly, due to high levels of financial distress experienced by participants and its relation to return to work, designing rehabilitation programs to facilitate cancer survivor return to work should be considered.

Objectives: This study was undertaken to evaluate AmpC β-lactamase-producing Escherichia coli urine isolates and to characterize the frequency of plasmid-mediated AmpC (pAmpC)-encoding genes.Methods: Antimicrobial susceptibility tests were performed using the disk diffusion technique. AmpC β-lactamase production was assessed with a phenotypic inhibitor-based method. The presence of 6 pAmpC-encoding cluster genes was detected by multiplex polymerase chain reaction (PCR).Results: The proportion of antibiotic resistance of E. coli isolates ranged from 7.4% to 90.5%, and more than half (51.6%) of the total isolates were multidrug-resistant (MDR). Among the 95 E. coli isolates, 60 (63.2%) were found to be cefoxitin-resistant, but only 14 (14.7%) isolates were confirmed as AmpC β-lactamase-producers. In the PCR assay, pAmpC-encoding genes were found in 15 (15.8%) isolates, and blaDHA was the most prevalent type. However, blaFOX, blaMOX, and blaACC genes were not detected in the isolates.Conclusion: Our findings contributed valuable information concerning antibiotic resistance, confirmatory phenotypic testing for AmpC production, and pAmpC β-lactamase gene content in E. coli isolates in southwestern Iran. The level of MDR recorded in AmpC-producing strains of this study was worrying; therefore, implementing strong infection control approaches to reduce the MDR burden is recommended.
