Assessment of heavy metal levels of Agodi Reservoir in Ibadan, Nigeria

The quality of water discharged into Agodi Reservoir was determined by the levels of Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb and Zn. Water samples were collected from the inlet, centre and outlet locations of the reservoir and their heavy metal contents were determined by standard methods using Atomic Absorption Spectrophotometer (AAS) over a period of twelve (12) months covering both rainy and dry seasons. Test location differences and seasonal variations were examined using ANOVA at P<0.05 to establish any gradient effect associated with pollution dynamics. Results showed no seasonal variations in all the heavy metals except for Co. Also, there is no significant variation in heavy metal concentration between the test locations. The heavy metal profile in Agodi Reservoir, measured in mg/L, was as follows: Mn (64.81) > Fe (43.75) > Zn (23.13) > Cu (12.44) > Co (0.19) > Ni (0.17) > Cd (0.12). Concentrations of Cr and Pb were below detectable level. Compared to WHO recommended limits, Co fell below while others were higher than thresholds. It is concluded that Agodi Reservoir water has a potential environmental hazard unless treated before use.

Reliability and Validity of the Persian Version of Child Asthma Self-Efficacy Scale

Background: This study aimed at assessing psychometric properties of the Iranian version of child asthma self-efficacy scale. Methods: The present study was a descriptive-survey research. The community sample included healthy and asthmatic children and adolescents, aged 8 to 18 years old from the city of Ahvaz. The sample consisted of 261 children, 61 patients referred to clinics of asthma and allergies and 200 healthy children that were selected by the random cluster sampling method. Child Asthma Self-Efficacy scale and child general self-efficacy questionnaire were used. Chronbach’s alpha coefficient, Pearson correlation, two sample t test, and confirmatory factor statistical analyses were applied. Results: Internal consistency for total scale score (α = 0.82), attack prevention subscale score (α = 0.704), and attack management subscale score (α = 0.70) were acceptable for this scale. Validity was demonstrated using correlation of total score and two subscales with child general self-efficacy and its academic and social subscale, indicating that all correlations were acceptable at 0.05 level. Two sample t test was used between patient sample and healthy sample that showed a significant difference between 2 subject groups. As a result of confirmatory factor analysis, it seems that it is better to use total score of this questionnaire in the Iranian sample. Conclusions: The results demonstrated allowable reliability and validity of the child asthma self-efficacy scale. The child asthma self-efficacy scale could be applicable in clinical trials, research, and clinical practice for more improvement and committed behavior regarding treatment regimes in children with asthma.
JOTE: Joint Offloading of Tasks and Energy in Fog-Enabled IoT Networks

Fog computing is a promising solution to enable delay-sensitive applications in the Internet of Things (IoT). In this article, based on the simultaneous wireless information and power transfer (SWIPT) technology, we investigate the joint offloading of tasks and energy (JOTE) in fog-enabled IoT networks. Specifically, the task node is allowed to offload energy and tasks to multiple neighboring helper nodes in a time-division multiple access (TDMA) manner. When there are no task queues in the nodes, the offloading decision for each task is independent. We first find the offloading strategy to minimize the task execution delay as well as the energy consumption for a specific task and then, analyze the condition under which the JOTE is beneficial. We show that it becomes more and more desirable to offload both the tasks and the energy from the task node as the number of helper nodes gets large. When there are task queues in the nodes, the offloading decision for each task becomes temporally correlated. We then characterize the optimal strategies to offload the tasks and energy jointly over multiple time slots. An online offloading policy based on the Lyapunov optimization is then proposed to minimize the time average expected delay while stabilizing the system operation. Comprehensive numerical results corroborate our theoretical results and demonstrate the superior performance of the proposed JOTE algorithms.

Prevalence and prevention of brucellosis in cattle in Lebanon

Background and Aim: Brucellosis is a zoonotic disease caused by the bacterium of the genus Brucella. This disease is present worldwide, especially in developing and underdeveloped countries, where it is endemic. This first-of-its-kind study in Lebanon aimed to assess the prevalence of brucellosis across the country and to determine the efficacy of a vaccine for reducing losses in herds so that its toll on public health is reduced. Materials and Methods: Three hundred and fifty-three blood serum and 261 milk samples were obtained from cows in different areas of Lebanon. The samples were analyzed using serological tests (rose Bengal, milk ring, and indirect enzyme-linked immunosorbent assay [ELISA]) and confirmed with competitive ELISA and polymerase chain reaction. Results: The highest rate of Brucellae was found in the Bekaa region (10%). After vaccination of 5 cows and 13 heifers at different times, the results showed that all the vaccinated animals have developed an immune response to brucellosis 60 days after vaccination. This vaccine can be considered as stable and preventative to protect against brucellosis in animals and thus protect the public from this infection. Conclusion: These findings will provide further insight into designing future targeted awareness interventions and adapted policies as efforts toward reducing the prevalence and prevention of brucellosis in cattle in Lebanon.
High temperature composite membranes based on polybenzimidazole and dendrimer amine functionalized SBA-15 mesoporous silica for fuel cells

In this study SBA-15, melamine-based dendrimer amine functionalized SBA-15 mesoporous silica (MDA-SBA-15), and the 1,3-di(3-methylimidazolium) propane dibromide dicationic ionic liquid (pr(mim)2Br2) were used in order to improve the proton conductivity, and thermal and mechanical stability of phosphoric acid (PA) doped polybenzimidazole (PBI)-based composite membranes for application in high-temperature proton exchange membrane (PEM) fuel cells. The effect of the porous structure of the mesoporous silica on the performance of the PA doped PBI-based membrane containing pr(mim)2Br2 was investigated under high temperature. The experimental results implied that MDA-SBA-15 containing the groups of NH2, and melamine-based dendrimer amines (MDA) on the internal wall of its pores provides special sites for further interaction with pr(mim)2Br2, PBI, and PA in the composite membranes. The presence of NH2 and MDA groups plays an important role in creating several pathways for proton exchange in the composite membranes. The PA-doped PBI-based composite membranes containing 4.5% w/w pr(mim)2Br2, and 1.5% w/w MDA-SBA-15 exhibit a high proton conductivity of 0.22 S cm−1 at 180 °C under dry conditions. The current density of 1.18 A cm−2, and power density of 0.60 W cm−2 at 0.50 V and 180 °C confirm the enhanced potential of the PA doped PBI-based composite membranes for application in high-temperature PEM fuel cells.
Assessment of the Efficacy of Rifaximin in the Management of Irritable Bowel Syndrome (IBS)

The aim of our study was to assess in our context, the efficacy of Rifaxim in improving the symptoms of irritable bowel syndrome particularly in its diarrheal (IBS-D) or mixed (IBS-DC) component and therefore assess its impact on patients’ quality of life. Patients and methods: This was an uncontrolled, non-comparative prospective cohort study of a single group of patients. Patients recruitment was done in two University Hospitals for 6 months (September 2015-February 2016). Were included ambulatory patients, male or female, aged 18 - 75 years, with diarrheic IBS (IBS-D) or mixed IBS (IBS-DC) diagnosed according to Rome III criteria and who agreed to participate in the study. Each patient received 400mg Rifaximin × 2/d for 15 days. The overall assessment of the efficacy of treatment at D15 (end of treatment) and D30 (2 weeks post-treatment) was the primary criterion of judgment. The statistical tests used were the Chi-square test and Fisher’s exact test for the qualitative variables and Student’s test for the quantitative variables. Results: A total number of 30 patients (16 women) with an average age of 44.5 ± 13.9 years were included. The overall assessment of symptoms by the patient with the Likert scale found 28 (93.3%) patients, 12 (40%) patients and 10 patients (33.3%) for a scale ≥2 at D0, D15 and D30 respectively. The assessment of the intensity of pain or abdominal discomfort found at D0, D15 and D30 respectively: 27(90%), 13(43.4%) and 6(20.1%) patients who had an EVA score > 2. The mean score for Francis to assess the improved quality of life was 247.1 ± 97.4 at D0, 99.8 ± 63.1 at D15 and 128.8 ± 70.6 at D30. Conclusion: There is a good overall improvement of symptoms in our patients suffering from IBS-D or mixed (IBS-DC) on Rifaximin with improvement of the quality of life.
Tumor control via targeting PD-L1 with chimeric antigen receptor modified NK cells

Failed T cell-based immunotherapies in the presence of genomic alterations in antigen presentations pathways may be overcome by NK cell-based immunotherapy. This approach may still be limited by the presence of immunosuppressive myeloid populations. Here we demonstrate that NK cells (haNKs) engineered to express a PD-L1 chimeric antigen receptor (CAR) haNKs killed a panel of human and murine head and neck cancer cells at low effector-to-target ratios in a PD-L1-dependent fashion. Treatment of syngeneic tumors resulted in CD8 and PD-L1-dependent tumor rejection or growth inhibition and a reduction in myeloid cells endogenously expressing high levels of PD-L1. Treatment of xenograft tumors resulted in PD-L1 dependent tumor growth inhibition. PD-L1 CAR haNKs reduced levels of macrophages and other myeloid cells endogenously expressing high PD-L1 in peripheral blood from patients with head and neck cancer. The clinical study of PD-L1 CAR haNKs is warranted.
Storage methods, phenolic composition, and bioactive properties of Apis mellifera and Trigona spinipes pollen

The aim of this study was to evaluate the influence of lyophilization and drying in stove on phenolic compounds content and the biological activity of Apis mellifera and Trigona spinipes pollens produced in Brazil. In general, the bee pollen produced by T. spinipes presented highest antioxidant activity in dried and fresh samples assessed either by test of plasma ferric reduction capacity (FRAP) and free radical scavenging assay (DPPH) methods. For A. mellifera bee pollen the antioxidant activity was higher on the fresh samples. Nevertheless, β-carotene bleaching assay (BCB) and linoleic acid content were higher in T. spinipes samples, mainly in the fresh ones. Higher antioxidant activity was owing to higher content in phenolic compounds. Lyophilization method was the best for phenolic compounds’ conservation for both species. The bee pollen of both species has a high amount of flavonoids: kaempferol-3-O-glucoside was the most abundant in A. mellifera while for T. spinipes the most prevalent was resorcylic acid + epicatechin. All extracts presented antibacterial activity against Saphylococcus aureus (ATCC 43300)™, (ESA 83138150), (ESA 32), Pseudomonas aeruginosa (ATCC 15442)™, Pseudomonas aeruginosa (MRC.4) and (MRC.10). The methods used for storage influenced the biological properties of bee pollen from both species. Regarding the content of phenolic compounds, differences were observed amongst the pollen types: for A. mellifera these were best preserved with lyophilization, while for T. spinipes the three storage methods were equivalent.
[RADAR: a program for the prevention of suicide in adolescents in the region of Aysen, Chile, preliminary results].

OBJECTIVE We present the preliminary results of the implementation of RADAR: a community suicide prevention program in adolescents implemented in two high schools in a south region of Chile. METHOD In a pilot study, during 2016, we implemented RADAR in two high schools of Puerto Aysen, in in the Region of Aysen of Chile. A total of 409 actors were trained (among students, school teachers, caregivers and health professionals) for the screening and referral of high suicide risk adolescents. RESULTS Out of a total of 144 students who passed the RADAR screening systems, 29 cases were detected as suicide risk (20%) and 27 of them were opportunely referred to the Emergency Service of the Hospital of Puerto Aysen. In the second RADAR screening campaign, 3 months later, 90% of the cases no longer presented suicide risk. CONCLUSION These results show the high proportion of ado lescents at risk of suicide who are not visible by the health system and the feasibility of implementing RADAR in the community as an effective suicide prevention intervention.
Tetrafluorosubstituted Metal Phthalocyanines: Interplay between Saturated Vapor Pressure and Crystal Structure

In this work, we study the effect of fluorosubstitution on the crystal structure of phthalocyanines of copper, cobalt, and vanadyl and analyze the correlations between the structure and volatility of these complexes. The structures of MPcF4 (M = Cu, Co, VO) single crystals were refined; their vapor pressure was determined as a function of temperature by the Knudsen effusion method and the standard thermodynamic parameters ΔHT and ΔST0 of the sublimation process were determined. These characteristics were compared with those of unsubstituted MPc and hexadecafluorosubstituted derivatives. Hirshfeld surface analysis was used as a powerful tool for the visualization and better insight into intermolecular contacts in these molecular structures.
Promoting Clinical Breast Examination as A screening Tool for Breast Cancer in Iraq

Breast cancer constitutes about one fourth of the registered cancer cases among the Iraqi population (1)and it is the leading cause of death among Iraqi women (2). Each year more women are exposed to the viciousramifications of this disease which include death if left unmanaged or the negative sequels that they wouldexperience, cosmetically and psychologically, after exposure to radical mastectomy.The World Health Organization (WHO) documented that early detection and screening, when copedwith adequate therapy, could offer a reduction in breast cancer mortality; displaying that the low survival ratesin less developed countries, including Iraq, is mainly attributed to the lack of early detection programs coupledwith inadequate diagnostic and treatment facilities (3). Although mammography machines, as main screeningtools for breast cancer, are available in the major hospitals in each province in Iraq, yet those are mainly usedfor diagnostic purposes in patients who present with palpable breast lumps. Obviously, due to cost effectivemeasures, lack of resources and the economical challenges that Iraq is facing, it is not expected that theauthorities could provide mammography devices across every health care centre in the country to be used forscreening of all Iraqi women.Accordingly, promoting other feasible tools could support in solving that dilemma. Clinical BreastExamination (CBE) for women, by highly trained health care providers in Primary Health Care Centers, alongwith diagnostic mammography in the major hospitals for referred cases, could offer cost effective approachesfor early detection of breast cancer in Iraq. The resources required to provide these services are within thereach of all countries with limited resources(4). The issue of raising awareness on breast cancer and its early detection measures needs to be addressed.Observations reported in Iraqi studies obviously reflect the the limited knowledge of the general populationabout the disease, its preventive measures and their ignorance regarding the significance of CBE and earlymedical consultation (5, 6). Public health awareness campaigns should be endorsed by policy makers to encourage every Iraqi women to look for abnormal signs and symptoms in their breasts and to seek medicaladvice promptly.
Correlation and impact of metabolic syndrome in bipolar disorder

Bipolar Disorder is a chronic episodic illness with frequent alterations of mania and depression. Various physical problems are known to affect the course and outcome of Bipolar Disorder. Out of them metabolic syndrome is a well known co-morbid condition which shares common risk factors and also worsens the disease course, may contribute to premature mortality in Bipolar Disorder. Hence, the knowledge about the metabolic abnormalities in Bipolar Disorder can help us in planning the treatment of Bipolar Disorder to get better prognosis. In this background the present study was conducted in patients with Bipolar Disorder to assess the relationship between them. Increasing age, more number of lifetime depressive episodes and the more total number of lifetime episodes appear to be predictors for the occurrence of metabolic syndrome in patients with Bipolar disorder. We thus have valuable insight about the relationship between metabolic syndrome and Bipolar disorder. The presence of metabolic syndrome influences the course and severity of the illness. It is possible to detect the presence of the metabolic syndrome and its components in the early stages of their development and plan timely intervention. This would help in altering the course and severity of the illness in a favorable manner.
The Effects of Online Trust-Building Mechanisms on Trust in the Sharing Economy: The Perspective of Providers

Trust is considered to be one of the key factors influencing the sustainable development of the sharing economy. In this paper, we focus on the trust issue of peer-to-peer accommodation models like Airbnb and Xiaozhu, which are among the most common examples of a sharing economy. This research divides trust into two types from the perspective of an accommodation provider in the context of peer-to-peer accommodation sharing: trust in the sharing platform and trust in consumers. The purpose of this paper is to provide a comprehensive view of how the three types of online trust-building mechanisms affect providers’ trust in the sharing platform and trust in consumers. The structural equation modelling with partial least square method was used to empirically test the influence of the online trust-building mechanisms of a sharing economy platform on provider’s trust in the platform and provider’s trust in consumers, based on a sample of 209 providers on online short-term rental platforms in China. The empirical results show that perceived personal safety mechanisms, perceived property safety mechanisms, and perceived review mechanisms are positively related to a provider’s trust in the platform. Provider’s trust in the platform has a positive effect on trust in consumers, while perceived personal safety and review mechanisms have a positive effect on provider’s trust in consumers by the mediation of trust in the platform. This study has theoretical and practical significance for the promotion of the research and development of trust mechanisms in the sharing economy.
Perspective of Microbe-based Minerals Fortification in Nutrition Security

ABSTRACT In recent years, probiotics have been increasingly proposed as health-promoting supplements in variety of food systems because of their physiological function and technological characteristics. Though there are large documents concerning the health benefits from these functional microbes, only a few literatures stated the requirements for mineral enhancement in food industry. Due to the health maintenance and specific supplementary demand, this review aims at proposing the screen routes for functional microbes selection on micronutrient supplement and the action on human health. In this article, the selection strategies of different functional strains for safe dietary supplement are investigated and proposed according to the health and security legislation. Moreover, the confirmed strain as micronutrient supplement or producer, including vitamins, selenium, chromium, iron, and zinc elements were summarized and discussed. This paper also reviews the studies of probiotics widely recognized health effects and provides the practicing dietitian some basics on supplement recommendations to better serve consumers.
Elektrische Kapazitätstomografie mit phantomabhängiger Adaptivität

Zusammenfassung In der elektrischen Kapazitätstomografie (ECT) verbessert sich die Auflösung der rekonstruierten Permittivitätsverteilung mit der Elektrodenanzahl, wohingegen die Anzahl der Kapazitätsmessungen und die Messzeit steigt und das Signal-Rausch-Verhältnis sinkt. Um einen Kompromiss zwischen Elektrodenanzahl und Auflösung zu finden, haben wir ein phantomabhängiges Adaptionsverfahren untersucht, in dem grobe Messungen mit verbundenen Einzelelektroden, die quasi synthetische größere Elektroden darstellen, durchgeführt werden. Das Verfahren wurde anhand eines Kunststoffzylinders im Erfassungsbereich im Inneren eines Rohres getestet. Wir vergleichen die rekonstruierten Ergebnisse basierend auf den Kapazitäten zwischen sechs synthetischen Elektroden und zwölf elementaren Elektroden sowie mit dem Adaptionsverfahren, das sowohl die Kapazitäten zwischen den sechs synthetischen Elektroden als auch zwischen einigen der elementaren Kapazitäten auswertet. Die Permittivitätsverteilung wird mit dem projizierten Landweber-Algorithmus einerseits aus berechneten Kapazitäten (Simulation mit der Finite-Elemente-Methode, FEM) und andererseits aus gemessenen Kapazitäten rekonstruiert. Die Kapazitäten werden dabei für jeweils zwei Fälle bestimmt. Im ersten Fall werden die Elektroden, die gerade nicht Teil der betrachteten Kapazität sind, geerdet, im zweiten Fall sind sie potentialfrei. Die Ergebnisse zeigen, dass im Erdungsfall die Rekonstruktionsergebnisse der gemessenen Kapazitäten mit dem Adaptionsverfahren sogar verbessert werden können. Im potentialfreien Fall und bei den Simulationen konnte das Phantom nur mit einer Verschlechterung der Auflösung dargestellt werden.
