Abstract
Mobile phones and Wi-Fi radiofrequency radiation are among the main sources of the exposure of the general population to radiofrequency electromagnetic fields (RF-EMF). Previous studies have shown that exposure of microorganisms to RF-EMFs can be associated with a wide spectrum of changes ranged from the modified bacterial growth to the alterations of the pattern of antibiotic resistance. Our laboratory at the nonionizing department of the Ionizing and Non-ionizing Radiation Protection Research Center has performed experiments on the health effects of exposure to animal models and humans to different sources of electromagnetic fields such as cellular phones, mobile base stations, mobile phone jammers, laptop computers, radars, dentistry cavitrons, magnetic resonance imaging, and Helmholtz coils. On the other hand, we have previously studied different aspects of the challenging issue of the ionizing or nonionizing radiation-induced alterations in the susceptibility of microorganisms to antibiotics. In this study, we assessed if the exposure to 900 MHz GSM mobile phone radiation and 2.4 GHz radiofrequency radiation emitted from common Wi-Fi routers alters the susceptibility of microorganisms to different antibiotics. The pure cultures of Listeria monocytogenes and Escherichia coli were exposed to RF-EMFs generated either by a GSM 900 MHz mobile phone simulator and a common 2.4 GHz Wi-Fi router. It is also shown that exposure to RF-EMFs within a narrow level of irradiation (an exposure window) makes microorganisms resistant to antibiotics. This adaptive phenomenon and its potential threats to human health should be further investigated in future experiments. Altogether, the findings of this study showed that exposure to Wi-Fi and RF simulator radiation can significantly alter the inhibition zone diameters and growth rate for L monocytogenes and E coli. These findings may have implications for the management of serious infectious diseases.

Abstract
Detection of leishmaniasis is important in clinical diagnoses. In the present study, identification of Leishmania parasites was performed by a label-free, PCR-free and signal-on ultrasensitive electrochemical DNA biosensor. Gold nanoleaves were firstly electrodeposited by an electrodeposition method using spermidine as a shape directing agent. The biosensor was fabricated by immobilization of a Leishmania major specific DNA probe onto gold nanoleaves, and methylene blue was employed as a marker. Hybridization of the complementary single stranded DNA sequence with the biosensor under the selected conditions was then investigated. The biosensor could detect a synthetic DNA target in a range of 1.0×10-10 to 1.0×10-19molL-1 with a limit of detection of 1.8×10-20molL-1, and genomic DNA in a range of 0.5-20ngμL-1 with a limit of detection of 0.07ngμL-1. The biosensor could distinguish Leishmania major from a non-complementary-sequence oligonucleotide and the tropica species with a high selectivity. The biosensor was applicable to detect Leishmania major in patient samples.

Abstract
Background CAN-003 was a randomized, open-label, Phase 2 trial evaluating the safety, efficacy and immune outcomes of CVac, a mucin 1 targeted-dendritic cell (DC) treatment as a maintenance therapy to patients with epithelial ovarian cancer (EOC). Methods Patients (n = 56) in first (CR1) or second clinical remission (CR2) were randomized (1:1) to standard of care (SOC) observation or CVac maintenance treatment. Ten doses were administered over 56 weeks. Both groups were followed for progression-free survival (PFS) and overall survival (OS). Results Fifty-six patients were randomized: 27 to SOC and 29 to CVac. Therapy was safe with only seven patients with Grade 3–4 treatment-emergent adverse events. A variable but measurable mucin 1 T cell-specific response was induced in all CVac-treated and some standard of care (SOC) patients. Progression free survival (PFS) was not significantly longer in the treated group compared to SOC group (13 vs. 9 months, p = 0.36, hazard ratio [HR] = 0.73). Analysis by remission status showed in the CR1 subgroup a median PFS of 18 months (SOC) vs. 13 months (CVac); p = 0.69 (HR = 1.18; CI 0.52–2.71). However CR2 patients showed a longer median PFS in the CVac-treated group (median PFS not yet reached, >13 vs. 5 months; p = 0.04, HR = 0.32 CI). OS for CR2 patients at 42 months of follow-up showed a difference of 26 months for SOC vs. > 42 months for CVac-treated (as median OS had not been reached; HR = 0.17 (CI 0.02–1.4) with a p = 0.07). Conclusions CVac, a mucin 1-dendritic cell maintenance treatment was safe and well tolerated in ovarian cancer patients. A variable but observed CVac-derived, mucin 1-specific T cell response was measured. Notably, CR2 patients showed an improved PFS and lengthened OS. Further studies in CR2 ovarian cancer patients are warranted (NCT01068509). Trial registration NCT01068509. Study Initiation Date (first patient screened): 20 July 2010. Study Completion Date (last patient observation): 20 August 2013, the last patient observation for progression-free survival; 29 April 2015, the last patient was documented regarding overall survival.

Abstract
Burn wound infection is a major cause of morbidity and mortality in burn victims. Pseudomonas and Acinetobacter species are among the most common organisms complicating burn wounds. Presence of extended spectrum ß-lactamase (ESBL) and metallo-ß-lactamase (MBL) genes plays an important role in spreading ß-lactam resistant strains of these organisms and is a serious condition in the treatment of the affected patients. As a result, we aimed to determine the prevalence of SHV, TEM, PER and VIM ß-lactamases in Pseudomonas and Acinetobacter species isolates from burn wound swabs of children with burn injury. In this descriptive observational study, 107 Pseudomonas and Acinetobacter isolates collected from burn patients were subjected to PCR assay. Using PCR method and DNA sequencing, the existence of SHV-, TEM-, PER- and VIM-type ß-lactamase encoding genes were determined. Out of the 107 Pseudomonas and Acinetobacter isolates, 66 (77.6%) were ESBL positive, 26.2% were positive for SHV gene, 37.4% were positive for TEM gene, 14% were positive for PER gene and 15.9% of them harbored VIM gene. More than half of the Pseudomonas and Acinetobacter strains in our pediatric burn unit harbor ß-lactamase encoding genes that make them resistant to a wide range of ß-lactam antibiotics. Consequently, it is suggested to choose an appropriate antibiotic regimen based on the antibiogram pattern of the strains.

Abstract
We examine the ordering properties of rectangular hard rods with length L and diameter D at a single planar wall and between two parallel hard walls using the second virial density-functional theory. The theory is implemented in the three-state Zwanzig approximation, where only three mutually perpendicular directions are allowed for the orientations of hard rods. The effect of varying shape anisotropy is examined at L/D=10,15,and20. In contact with a single hard wall, the density profiles show planar ordering, damped oscillatory behavior, and a wall-induced surface ordering transition below the coexisting isotropic density of a bulk isotropic-nematic (I-N) phase transition. Upon approaching the coexisting isotropic density, the thickness of the nematic film diverges logarithmically, i.e., the nematic wetting is complete for any shape anisotropy. In the case of confinement between two parallel hard walls, it is found that the continuous surface ordering transition depends strongly on the distance between confining walls H for H<L, while it depends weakly on H for H>L. The minimal density at which a surface ordering transition can be realized is located at around H∼2D for all studied shape anisotropies due to the strong interference effect between the two hard walls. The first-order I-N phase transition of the bulk system becomes a surface ordered isotropic I_{B} to capillary nematic N_{B} phase transition in the slit pore. This first-order I_{B}-N_{B} transition weakens with decreasing pore width and terminates in a critical point for all studied shape anisotropies.

Abstract
BACKGROUND Drug resistance is widely believed to be an increasingly serious threat to global public health. We have previously reported that short term exposure of microorganisms to diagnostic ultrasound waves could significantly alter their sensitivity to antibiotics. In our previous studies, Klebsiella pneumoniae showed major differences in the sensitivity to antibiotics in exposed and non-exposed samples. This study was aimed at investigating the alteration of antibiotic resistance of Klebsiella pneumonia, after exposure to Wi-Fi 2.4 GHz electromagnetic radiofrequency radiation. MATERIALS AND METHODS In this in vitro study, three replicate agar plates were used for each test. The antibiotic susceptibility test was carried out using disc diffusion method on Mueller Hinton agar plates and the inhibition zones in both control and exposed groups were measured. A common Wi-Fi router was used in this study as the radiofrequency exposure source. Irradiated samples were exposed to Wi-Fi radiofrequency radiation for 3, 4.5 and 8 hours. RESULTS Statistically significant variations of sensitivity to antibiotics were found for all studied antibiotics after 4.5 hours of RF exposure, compared to non-exposed bacteria. Interestingly, the mean diameters of the inhibition zones after 3 hours of exposure were less than those exposed for 4.5 hours. Following this rise in the sensitivity to antibiotics, a fall was observed in the bacteria exposed for 8 hours for all studied antibiotics. CONCLUSION The findings of this study show a statistically significant rise in the sensitivity of Klebsiella pneumoniae to different antibiotics after 4.5 hours of exposure to 2.4 GHz Wi-Fi radiation, followed by a fall after 8 hours of exposure. These observations can be interpreted by the concept of non-linearity in the responses of Klebsiella pneumoniae to different antibiotics after exposure to electromagnetic radiofrequency radiation. As in this study a minimum level of effect was needed for the induction of adaptive response, these results also confirm the validity of the so-called "window theory".

Abstract
SETTING Waterpipe smoking is an emerging topic in tobacco research that may have unrecognised health hazards. OBJECTIVE To determine whether waterpipes are a source of bacterial contamination. METHODS A total of 15 restaurants and waterpipe cafés were randomly selected from the list of locations serving waterpipe tobacco in Kerman city, Iran. Different parts of the waterpipe devices were sampled, including the disposable mouthpiece, the mouthpiece of the hose and the water in the bowl of the waterpipe. The samples were smeared onto bacterial culture media, including eosin methylene blue, blood agar and MacConkey agar growth media, and incubated at 37°C. After 24-48 h, they were examined for colony growth. RESULTS Of 285 samples from different parts of the waterpipes, 236 (82.8%) showed positive cultures; the rate of contamination ranged from 69% in the fixed mouthpiece to 96% in bowl water. Coagulase-negative staphylococci (32.9%), Streptococcus spp (26.9%), Neisseria spp (13.7%) and Escherichia coli (9.4%) were the most frequent contaminants. CONCLUSION Waterpipes are frequently contaminated with microorganisms. This study revealed potential microbial hazards in waterpipes that may contribute to respiratory tract colonisation.

Abstract
BACKGROUND Knowledge about harmful effects of morphine on hormone secretion seems to be necessary. The aim of the present study was to evaluate the effect of pentoxifylline on side effects derived by morphine on hypophyso-gonadal hormones of male rats. METHODS 32 male rats were divided into the 4 groups of OSS: control (received 40 g Sucrose/l drinking water and intraperitoneal injection of 1 l/kg normal saline), OMS: morphine group (received 0.4 mg/l + 40 g Sucrose/l in drinking water and intraperitoneal injection of 1 l/kg normal saline), NMS: morphine+naltrexane group (received 0.4 mg/l + 40 g Sucrose/l in drinking water and IP injection dose of 10 mg/kg/ml/day Naltrexane) and PMS: morphine + pentoxifylline group (received 0.4 mg/dl + 40 g Sucrose/l in drinking water and IP injection dose of 12 mg/kg/ml/day Pentoxifylline) for 56 days, respectively. RESULTS Serum levels of testosterone, LH, FSH hormones were measured. Pentoxifylline increased serum levels of testosterone, LH, FSH hormones compared to control, morphine and morphine-naltrexane groups. CONCLUSION Pentoxifylline has a significant efficacy for increasing serum levels of sexual hormones. Considering that Pentoxifylline is safe and cheap, with easy application, we suggest for the usage of this drug for improving semen parameter's quality before performing ART for the treatment of morphine addicts (Fig. 1, Ref. 31).

Abstract
Introduction & Objective: Ischemia heart disease (IHD) is the most often met reason for losses in different communities. The most common reason of IHD is Atherosclerosis, and various etiologic factors such as high blood pressure, diabetes, smoking, and hyperlipidemia are involved in its development. Anemia is also considered another resulting reason of loss and morbidity in patients via IHD. Accordingly, the current paper aimed to determine the prevalence of anemia in patients who survived and died of myocardial infarction. Materials and Methods: The present research is of a case-control type, and the subjects were the patients with myocardial infarction admitted to Heart Ward of Hamadan Ekbatan Hospital within one year (2012-2013). The patients were divided into two categories of demised and survived after myocardial infarction, and in each 160-subject group, the prevalence of anemia with hemoglobin levels was investigated. Moreover, the demographic characteristics, ejection fraction, and patients' underlying medical conditions were also taken into account. The data obtained were analyzed by SPSS 15 software and chi-square test. Results: Of the 320 patients studied, 61 patients (19.1%) had anemia and 51 (83.6%) patients who were anemic had died. 31.7% of the deceased patients after MI were weak, while 6.3% of the survived patients after MI were anemic. Also, in all age and sex groups, anemia in the former patient group was higher than in the sustained group. The predominance of anemia was clearly greater in the women than in the men (P < 0.05). Conclusion: Based on the findings, there is a statistically clear variation in the prevalence of anemia in the former patient group after MI than in the group who survived after MI.

Abstract
The hypothalamus and hippocampus are important areas involved in stress responses and reward processing. In addition, ERK/CREB pathway plays a critical role in the control of cellular responses to stress and reward. In the current study, effects of acute and subchronic stress on the alteration of p-ERK, p-CREB and c-fos levels in the hypothalamus and hippocampus of saline- or morphine-treated animals during morphine-induced conditioned place preference (CPP) procedure were investigated. Male Wistar rats were divided into two saline- and morphine-treated supergroups. Each supergroup includes of control, acute stress and subchronic stress groups. In all of groups, the CPP procedure was done, afterward the alternation of p-ERK/ERK ratio, p-CREB/CREB ratio and c-fos level in the hypothalamus and hippocampus were estimated by Western blot analysis. The results indicated that in saline- or morphine-treated animals, p-ERK/ERK ratio, p-CREB/CREB ratio and c-fos level increased after application of acute and subchronic stress (except for p-ERK/ERK ratio in morphine-control group). Our findings revealed that in saline- or morphine-treated animals, acute and subcronic stress increased the p-ERK/ERK ratio, p-CREB/CREB ratio and c-fos level in the hypothalamus and hippocampus and this enhancement in morphine-treated animals, was more considerable than that in saline-treated animals.

Abstract
A density functional theory (DFT) method (periodic DMol(3)) with full geometry optimization was used to study the adsorption of tautomeric forms of tetrazole on anatase TiO2 (101), (100), and (001) surfaces. It was found that the adsorption of tetrazole on the TiO2 surfaces does not proceed via a dissociative process, and negative shifts in the Fermi level of TiO2 were noted upon N-containing heterocycle adsorption. The configuration of the tetrazole during adsorption and the corresponding adsorption energies on different surfaces and sites were estimated. In addition, it was found that tetrazole may be adsorbed on TiO2 surfaces through an interaction between a cation on the surface and a lone pair on the N1 or N2 atom of the tetrazole molecule. The results indicate that the adsorption of tetrazole through the N2 position (leading to the 1H tautomer) on an anatase TiO2 surface is favored over adsorption through the N1 position. In addition, it was observed that the photocatalytic activity of tetrazole-doped TiO2 is higher than that of a pure anatase TiO2 surface.
