Serum CA19-9 as a predictor of incident metabolic syndrome in men over 50 years of age with obesity: a 9-year cohort study
Authors: Chang Pi-Kai , Hu Je-Ming , Wu Li-Wei
Published: August 2022

BackgroundThe tumor marker carbohydrate antigen (CA)19-9 is elevated in cancer and chronic diseases. However, the status of CA19-9 in metabolic syndrome (MetS), a common chronic disease in Asia, has not been thoroughly investigated. MethodsFrom 2007 to 2015, 1750 participants were retrospectively reviewed, and their routine health checkup data were obtained. The participants were divided into three groups based on their CA19-9 level. Their body mass index (BMI), waist circumference, and blood pressure were determined. Blood samples were collected from individuals after fasting for 8 h to determine biochemical parameters and tumor markers. MetS was defined according to the revised National Cholesterol Education Program’s Adult Treatment Panel III. Association between CA19-9 levels and incident MetS was evaluated using Cox regression models.ResultsThe group with the highest CA19-9 level tended to exhibit incident MetS (p = 0.002, HR = 2.44, 95% CI 1.39–4.27), and type 2 diabetes mellitus (p < 0.001, HR = 4.27, 95% CI 2.07–8.12) after adjusting for covariates. The group with the highest CA19-9 level showed a significant correlation with the incidence of all MetS components: high systolic blood pressure (≥130 mm Hg; p < 0.001, HR = 2.45, 95% CI 1.50–4.00); high waist circumference (≥90 cm; p < 0.001, HR = 2.29, 95% CI 1.46–3.60); high fasting plasma glucose levels (≥100 mg/dL; p = 0.001, HR = 2.05, 95% CI 1.33–3.18); low high-density lipoprotein levels (≤50 mg/dL; p = 0.001, HR = 2.24, 95% CI 1.39–3.60); and high triglyceride levels (≥150 mg/dL; p = 0.001, HR = 2.20, 95% CI 1.40–3.48). Subgroup analyses of age, sex, and BMI-specific groups revealed that participants with obesity (BMI ≥ 24) in the highest CA19-9 tertile, male, and ≥ 50 years of age were significantly associated with incident MetS (p = 0.002, HR = 2.56, 95% CI 1.39–4.69; p = 0.001, HR = 1.88, 95% CI 1.28–2.76; and p = 0.002, HR = 2.75, 95% CI 1.44–5.25, respectively). ConclusionsOur results revealed a positive correlation between CA19-9 levels and MetS in men over 50 years of age with obesity.

Published: August 2022

Objective: The objective of this study was to evaluate the differences in brain activity between expert surgeons and novice medical residents based on electroencephalography (EEG). The first sub-goal was to assess the Microstate EEGlab toolbox and BCIlab toolboxes for data analysis and classification of the topographical features for microstate-based Common Spatial Pattern (CSP) analysis. Then, the second sub-goal was to compare microstate-based CSP with the conventional regularized CSP approach.Methods: After IRB approval, ten expert surgeons and 13 novice medical residents were recruited at the University at Buffalo. After informed consent, the subjects performed three trials of laparoscopic suturing and knot tying with rest periods in-between the task trials. 32-channel EEG was performed during the task performance that was used to analyze spatial patterns of brain activity in 8 expert surgeons (2 dropouts due to data quality) and 13 novice medical residents. Microstate analysis was applied as preprocessing to improve the signal-to-noise ratio before CSP analysis, distinguishing expert surgeons' brain activity from novice medical residents.Results: Microstate-based CSP analysis identified the significant channels based on the maximum spatial pattern vectors at the scalp. While novices had primarily the frontal cortex involved for a maximum of the spatial pattern vectors at the scalp, the experts had the hotspot of the spatial pattern vectors over the frontal and parietal cortices. Simple linear discriminant analysis with 10-fold cross-validation achieved more than 90% classification accuracy with microstate-based CSP, while the conventional regularized CSP could reach around 80% classification accuracy.Conclusion and Discussion: Microstate-based CSP analysis can identify an optimal set of channels for evaluating the differences in brain activity between expert surgeons and novice medical residents. Future studies can apply microstate-based monitoring of the temporal dynamics of the brain behavior for an individualized adaptive VR-based training paradigm.
Distributed Reinforcement Learning-based Memory Allocation for Edge-PLCs in Industrial IoT

Published: August 2022

The rapid growth of the number of devices in the industrial Internet of things (IIoT) has a huge influence in the amount of data involved. In order to alleviate the computing load of cloud servers and reduce the delay of data processing, edge-cloud computing cooperation has been introduced to the IIoT. General programmable logic controllers (PLCs), which have been playing important roles in industrial control systems, start to gain the ability of processing large amount of industrial data and sharing the workload of cloud servers. This transforms them into edge-PLCs. However, continuous influx of multiple types of concurrent production data stream against the limited capacity of built-in memory in PLCs bring a huge challenge. Therefore, ability to reasonably allocate memory resources in edge-PLCs to ensure data utilization and real-time processing has become one of the core means in improving the efficiency of industrial processes. In this paper, to tackle dynamic changes of arrival data rate over time at each edge-PLC, we propose to optimize memory allocation with Q-learning distributedly. The simulation experiments verify that the method can effectively reduce the data loss probability while improve the system performance.

Published: August 2022

Skin cancer is the most common form of cancer. Hence, the lives of millions of people are affected by this cancer every year. Approximately, it is predicted that the total number of cases of cancer will double in the next fifty years. It is an expensive procedure to discover skin cancer types in the early stages. Additionally, the survival rate reduces as cancer progresses. The current study proposes an aseptic approach toward skin lesion detection, classification, and segmentation using deep learning and a meta-heuristic optimizer called Harris Hawks Optimization Algorithm (HHO). The current study utilized the manual and automatic segmentation approaches. The manual segmentation is used when the dataset has no masks to use while the automatic segmentation approach is used, using U-Net models, to build an adaptive segmentation model. Additionally, the meta-heuristic HHO optimizer is utilized to achieve the optimization of the hyperparameters using 5 pre-trained CNN models (i.e., VGG16, VGG19, DenseNet169, DenseNet201, and MobileNet). Two are collected (i.e., "Melanoma Skin Cancer Dataset of 10000 Images" and "Skin Cancer ISIC" dataset) from two publically available sources. For the segmentation, the best-reported scores are 0.15908, 91.95%, 0.08864, 0.04313, 0.02072, 0.20767 in terms of loss, accuracy, Mean Absolute Error, Mean Squared Error, Mean Squared Logarithmic Error, and Root Mean Squared Error, respectively. For the "Melanoma Skin Cancer Dataset of 10000 Images" dataset, from the applied experiments, the best reported overall accuracy is 97.08% by the DenseNet169 pre-trained model. For the "Skin Cancer ISIC" dataset, the best reported overall accuracy is 96.06% by the MobileNet pre-trained model. After computing the results, the suggested approach is compared with 9 related studies.

Authors: farah Monzer azhari mahgoub , Mahari Rahel Gebreab
Published: August 2022

Background: Febrile seizure (FS) is one of the most common neurologic disorders in children. Electrolyte imbalance especially hyponatremia may have an important role in triggering the febrile seizure. The measure of serum electrolytes will be useful in predicting further seizures. This study aimed to investigate the effect of relative hyponatremia on the risk of recurrent febrile seizures.Methods: This prospective study was performed on 115 children (6-60 months) with convulsions, at the pediatric department of Ibrahim malik teaching hospital. the serum sodium was measured immediately after abortion of seizures and each patient was followed for 24 hours for assessment of recurrence.Of the 115 children, 47 (40.9 %) develop recurrent febrile seizures. Of those the majority were males 36 (76.6%) (P=0.01), 52(45.2%) age less than 12 months(P=0.001) , 26 (68.4%) have parents consanguinity(P=0.000) , and were first born child25 (53.2%). The mean serum sodium levels in patients with one and recurrent attacks , were 132.1, 136.1 meq/l, respectively (P=0.00).Conclusions: The serum sodium level was ominously lower in the recurrence group compared to the non-recurrent group. Measurements of serum sodium levels and hyponatremia diagnosis have a key role in predicting the FC recurrence. Therefore, doctors should be careful during fluid administration to febrile seizure patients.
Development of Bigels Containing Antifungal Agent for Vaginal Infection
Authors: NNensi
Published: August 2022

Objective
Bigels are developed and are unique semi-solid formulations that have captivated the interest of many researchers due to their significant benefits over ordinary gels. The goal of this research work was to create and characterize new bigels for drug delivery applications by combining Hydroxypropyl methylcellulose hydrogel with sorbitan monostearate oil (coconut and olive) based organogel. The microscopy revealed the presence of both aqueous & oil phases as bigel.
Methods
The hydrogels and organogels were prepared individually and then the bigels were prepared by mixing hydrogel and organogel in a defined ratio and then they were evaluated using physiochemical tests, in-vitro drug release, microscopy, etc. The microstructures and physicochemical characteristics of the bigel were tested using microscopy, viscosity measurement, mechanical analysis, and differential scanning calorimetry analysis.
Results
Tube inversion tests reveal that the bigel doesn’t flow under its own weight till 167 mins. The microscopy suggested that the gels exhibited fiber-like structures due to the trapping of the organogel inside hydrogel molecules; this entrapment was demonstrated to be uniformly accomplished, resulting in formulation stability, and the DSC study reveals that the terbinafine is not decomposed also after formulating in bigel, and the terbinafine bigel was also found to be stable. The drug-loaded gels demonstrated effective antibacterial activity against Candida species. The formulated bigel shows initial release in 2 hours and slowly release later in 4 hours. The formed bigel is found to be stable after 3 months with a pH range of 7.07 ± 0.04, showing good spreadability and drug content was 99.99 ± 0.75.
Conclusions
Terbinafine, the drug of preference for the treatment of bacterial vaginosis, demonstrated diffusion-mediated drug release when placed into bigels. In general, the produced bigels might be employed as delivery vehicles for drugs delivered vaginally.

Authors: R Nandhakumar , Elumalai Elakkiya , Gupta Krishna Kant
Published: August 2022

Osteoarthritis has always been one of the most researched degenerative disorders pervasively. Moreover, this is been classified under complex disorders with an emphasis on the clinical analysis for the older people. However, a genomic understanding of the hereditary impact of this disease seems lacking. The basic genomic analysis has identified various biomarkers, but lacks prognosis. In this direction, we have retrieved publicly available RNA- seq data from the NCBI Sequence Read Archive (SRA). Utilising the Galaxy browser, the data analysis was performed to identify the differentially expressed genes from SRP IDs {ERP105501, SRP322624}. The overlaps of these studies revealed 105 upregulated and 127 downregulated genes. These sets were further processed for multi-omic analysis through the databases. We identified specific process involvement through the Gene Ontology followed by hub genes through Protein -protein interactions. In addition to this, the transcription factors were identified from the list through BART search and miRNAs interacting with the identified hub genes through miRNet. This study aims to perform genomic analysis of osteoarthritis by identifying the differentially expressed genes among multiple tissues from human osteoarthritis knee joint and further analyse to find the key genes, biological pathways, transcription factors and miRNAs that can be considered as hub genes of the Osteoarthritis disease in humans.

Authors: Morais Humberto , Feijão Ana , Pereira Savarino de Victória
Published: August 2022

Introduction: Studies on the normal echocardiographic reference values in Africans are limited.Objectives: This study aims to establish the normal left ventricular echocardiographic parameters for adult Angolans, stratified by gender and age.Methods: A cross-sectional study was performed involving healthy adults attending a diagnostic center in Luanda, Angola. The two-dimensional transthoracic echocardiography was performed according to the Guidelines of the American Society of Echocardiography and the European Association of Cardiovascular Imaging.Results: A total of 103 men (47.5%) (mean age: 39.5±10,8) and 114 women (52.5%) (mean age: 43.0±12,5 years) were included. Compared to men, women were older (p=0.025) and had a significantly smaller body surface area (BSA) (p<0.001). Left ventricular wall thickness, left ventricular end-diastolic dimension and volume (LVEDV), left ventricular mass (LVM) and LVM indexed to BSA (LVMi) were significantly lower in women (p<0.005). LVEDD indexed to BSA and left ventricular ejection fraction (LVEF) were significantly higher in women than in men (p=0.007), (p=0.01), respectively. Mitral annular plane systolic excursion, LVEF by strain, and global longitudinal strain showed no gender differences. Posterior wall thickness showed a statistically significant increase in the older groups (p=0.043). The VST, relative wall thickness, LVM, and LVMi showed no significant differences between age categories. In turn, the shortening fraction and the ejection fraction increase with age.Conclusion: For a more sensitive morphological and functional assessment of the left ventricle, it is necessary to take into account the gender and age of the individual.

Authors: Dianto Icol , Bakti Andi Faisal , Rosyidin Iding
Published: August 2022

Nasrudin Joha's ideology and discourse were one of the attempts to compensate for the dominance of rulers and capitalists. The criticism developed by Nasrudin Joha built the consciousness of the oppressed. With that awareness, Nasrudin Joha mobilized the oppressed to form a unified Islamic political identity and establish a caliphate system in Indonesia. This research aims to analyze Nasrudin Joha's strategy in building the ideology of the caliphate system and proclaiming it through social media. The authors used qualitative research methods in the field of mass media and used critical discourse analysis. The focus of his study was ideology and discourse in an article written by Nasrudin Joha on an online media platform. The results of this study found that Joha had used the theory of active reception to the readers. Joha positioned himself as the opposition and voiced the aspirations of the oppressed. In developing ideology and discourse about the caliphate system, Joha has similarities with the flow of Marxism, namely the resistance of the oppressed. On the other hand, Joha has a tendency to follow post-Marxist notions of freedom and oppose the oppression of the regime and capitalist groups.

Household behavioral intention, environmental habit and attitude related to efficient water management: an empirical analysis on pro-environmental behavior among urban residents
Authors: Sarpong Kwabena Agyarko , Amankwaa Gordon
Published: August 2022

The management of water utilities in urban contexts, which are particularly prone to water shortages and where future water security is of the utmost importance, has become a challenging task for the majority of municipal and regional planners. The present study attempts to evaluate how environmental knowledge and values influence possible pro-environmental behavior with respect to household water consumption behavior, attitudes, and habits among 500 (n = 313) urban dwellers in an urban setting in Jiangsu Province, China. We adapted the Theory of Planned Behavior (TPB) to elucidate pro-environmental behaviors while exploratory factor and Spearman correlation analysis were applied to datasets elicited from respondents. The study establishes important positive correlations using Spearman's rank (r = 0.50) based on the findings of our empirical analysis, which suggest that individuals with strong environmental values and rich environmental knowledge are more likely to exhibit behaviors, attitudes and habits that result in effective household water use and management. Additionally, based on the magnitude of the factor loadings, the key results from principal factor analysis were as follows: efficient household water consumption is contingent on fixing household leaks (0.73) and replacing old shower fixtures and water-using appliances (0.66). Nevertheless, China's water resources are insufficient and require efficient management (0.66), the quality of tap water supplies is compromised and cannot be trusted (0.66) and there has been little to no improvement in water quality and availability in the past 10 years in China (0.69). This research reinforces the role of knowledge in shaping behavior, and has policy effects and could serve as a benchmark for measures to reduce household water use.

Mulheres amantes e empreendimentos afetivos: um estudo socioantropológico das emoções e moralidades sobre o “Feminejo”
Authors: Barbosa Raoni , Costa Jean
Published: August 2022

O presente artigo buscou problematizar as noções êmicas de Amor acionadas no campo empírico da indústria cultural autointitulada Feminejo e da emergente juventude agrourbana brasileira consumidora destes discursos e práticas. Põe em relevo, nesse sentido, a lógica simbólico-interacional e moral-emocional em torno dos dramas cantados, encenados e vividos por artistas e pessoas comuns no formato de traição, amor autêntico, ser a outra, ser a amante, paixão de balada etc. Distante, porém, de buscar esgotar a análise sobre esse movimento ético-estético para o consumo juvenil massificado, o presente argumento, ainda em formato ensaístico próprio do momento inicial de pesquisa acadêmica, mergulha na categoria de mulheres amantes do empreendedorismo afetivo exemplificado no Feminejo. Para tanto, norteia-se no acúmulo teórico da Sociologia e Antropologia das Emoções e Moralidades sobre a Etnopsicologia Ocidental em suas noções densas de Self, Amor, Reciprocidade, Sentimentos e Emoções.
Abandono, solidão e desistência do amor: o racismo como elemento excludente de mulheres pretas no mercado do afeto

Published: August 2022

O artigo trata das desigualdades e hierarquias existentes no mercado do amor a partir do estudo de um público especifico, as mulheres pretas, quando buscamos identificar qual a mágica social (Bourdieu, 2004) que exclui essas mulheres do mercado do afeto. Em termos metodológicos, aplicamos questionários semiestruturados pelo google form e aplicamos presencialmente o mesmo questionário em um bairro popular de uma cidade do interior paulista. Os dados indicam o racismo como a mágica social que cria barreira no mercado do afeto; indica, também, que as tomadas de posição afetiva dessas mulheres não se encaixam em nenhuma das quatro abordagens catalogadas por nós sobre o amor (amor liquido, amor romântico, poliamor, amor confluente), chamando a atenção para novas teorias que possam dar conta da vivencia afetiva dessa população

Published: August 2022

Background

To empower healthy aging, digital solutions embed multiple modules for physical activity, cognitive health promotion, and social engagement. Integrating new empowering technologies such as digital exercise monitoring requires assessment measures and analysis procedures, considering variable compliance of users with different modules.

Objective

This study aims to assess the influence of a tablet-based and a feedback system–based exercise module on balance and leg strength by considering use adherence instead of the use of the entire multimodular system.

Methods

In the prospective cohort study within the fit4AAL project, 83 users (n=67, 81% women; n=16, 19% men; mean age 66.2, SD 2.3 years) used the 2 digital exercise modules of a multimodular physical activity promotion system for >18 weeks. A data-driven clustering method based on the average use frequency of the exercise modules determined the number of user types that met the World Health Organization–recommended training frequency of at least twice per week. On the basis of this use adherence, statistical analysis was performed with features of functional performance tests (unipedal stance, 30-second chair rise, Y-balance, and hurdle step tests). The tests were conducted 6 months before the intervention, immediately before the intervention, and after the intervention, comparing the baseline phase with the 3 feedback use groups of the study (using only the tablet, the tablet and the feedback system, or only the feedback system).

Results

Of the 83 users, 43 (52%) met the World Health Organization–recommended frequency of muscle-strengthening activities. Overall, the feedback use groups achieved, on average, more chair rises in 30 seconds than the baseline group (P=.01; moderate effect size of 0.07). Of the 43 users, 26 (60%) additionally used the feedback system–based exercise module. They improved in balance compared with the users using either the tablet or the feedback system (P=.02). In addition, they improved their leg strength within the group (P=.04) and compared with the baseline (P=.01).

Conclusions

The additional use of a feedback system showed a tendency to positively maintain and influence the already exceptionally high functional performance of older adults. Considering use adherence in future multimodular system studies is crucial to assess the influence of single and combined use of exercise modules on functional performance.
Predicting Patient Wait Times by Using Highly Deidentified Data in Mental Health Care: Enhanced Machine Learning Approach
Authors: Rastpour Amir , McGregor Carolyn
Published: August 2022

Background

Wait times impact patient satisfaction, treatment effectiveness, and the efficiency of care that the patients receive. Wait time prediction in mental health is a complex task and is affected by the difficulty in predicting the required number of treatment sessions for outpatients, high no-show rates, and the possibility of using group treatment sessions. The task of wait time analysis becomes even more challenging if the input data has low utility, which happens when the data is highly deidentified by removing both direct and quasi identifiers.

Objective

The first aim of this study was to develop machine learning models to predict the wait time from referral to the first appointment for psychiatric outpatients by using real-time data. The second aim was to enhance the performance of these predictive models by utilizing the system’s knowledge while the input data were highly deidentified. The third aim was to identify the factors that drove long wait times, and the fourth aim was to build these models such that they were practical and easy-to-implement (and therefore, attractive to care providers).

Methods

We analyzed retrospective highly deidentified administrative data from 8 outpatient clinics at Ontario Shores Centre for Mental Health Sciences in Canada by using 6 machine learning methods to predict the first appointment wait time for new outpatients. We used the system’s knowledge to mitigate the low utility of our data. The data included 4187 patients who received care through 30,342 appointments.

Results

The average wait time varied widely between different types of mental health clinics. For more than half of the clinics, the average wait time was longer than 3 months. The number of scheduled appointments and the rate of no-shows varied widely among clinics. Despite these variations, the random forest method provided the minimum root mean square error values for 4 of the 8 clinics, and the second minimum root mean square error for the other 4 clinics. Utilizing the system’s knowledge increased the utility of our highly deidentified data and improved the predictive power of the models.

Conclusions

The random forest method, enhanced with the system’s knowledge, provided reliable wait time predictions for new outpatients, regardless of low utility of the highly deidentified input data and the high variation in wait times across different clinics and patient types. The priority system was identified as a factor that contributed to long wait times, and a fast-track system was suggested as a potential solution.

Published: August 2022

BACKGROUND

Sexual minority men (SMM) experience intimate partner violence (IPV) at rates similar to those reported by heterosexual women in the United States (U.S.) Previous studies linked both IPV victimization and perpetration to HIV risk and seroconversion, but less is known about the impact of IPV on HIV testing, sexually transmitted infection (STI) testing/acquisition, pre-exposure prophylaxis (PrEP) uptake, and the persistence of PrEP use among SMM experiencing IPV. While prior work suggests IPV may influence HIV prevention behavior, experiences of IPV are so highly varied among SMM (e.g., forms, frequency, severity; steady vs. casual partnerships; perpetration vs. recipient; sexual vs. physical vs. psychological violence) that additional research is needed to better understand the impact IPV has on HIV risk and protective behaviors to develop more effective interventions for SMM.

OBJECTIVE

The overall aim of this study is to contribute to our understanding of the antecedents of IPV and the direct and indirect pathways between perpetration and/or receipt of IPV and HIV/STI risk behavior, STIs, and use of PrEP among SMM experiencing IPV.

METHODS

This mixed methods study utilizes two phases. Phase I involves formative qualitative interviews with 23 SMM experiencing IPV and with 10 key stakeholders/providers of services to SMM experiencing IPV to inform the content of a subsequent online cohort study. Phase II involves the recruitment of an online cohort study of 500 currently partnered HIV-negative SMM, who reside in CDC-identified Ending the HIV Epidemic (EHE) priority jurisdictions across the U.S. Participants will be followed for 24 months. Participants will be assessed with a full survey and asked to self-collect and return biospecimen kits assessing for HIV, STIs, and PrEP use at 0, 6, 12, 18, and 24 months. Participants will also be asked to complete abbreviated surveys to assess for self-reported changes in key study variables at 3, 9, 15, and 21 months. This mixed methods study will contribute valuable insights into the association IPV has on HIV risk and protective behaviors among SMM.

RESULTS

Phase I launched in May 2021 and the Phase I qualitative interviews began in December of 2021 and concluded in March 2022 once a diversity of experiences and perceptions were gathered and no new ideas were emerging in the interviews. We are currently analyzing the qualitative interviews. Recruitment of the full cohort will begin in August 2022.

CONCLUSIONS

The findings from this study will be used to inform the development or adaptation of HIV and IPV prevention interventions for SMM who are experiencing IPV.

Abstract: Asian redtail catfish (Hemibagrus nemurus Valenciennes, 1840) is one of Indonesian native fish species with high economic potency. However research on genetic variation of Asian redtail catfish in Indonesia is very limited. Therefore, this study purposed to identify and analyze the mitochondrial gene polymorphism 16S of Baung fish (H. nemurus) from the Progo River, Magelang, Central Java. The method used in this study was the PCR method with universal primers 16Sar and 16Sbr. Intraspecific genetic variation was conducted by combining mitochondrial gene 16S sequence data of five Asian redtail fish (H. nemurus) samples from Progo River (BGM 02-06) and five Asian redtail fish samples from GenBank. BLAST, DnaSP, DNASTAR, GeneStudio,, MEGA, Mesquite, and NETWORK programs were used to analyze the data obtained. The results showed there were no genetic differences among the Asian redtail fish from Progo River indicating no intrapopulation genetic variation of the fish species. Conversely, the intraspecific genetic divergence was between 0.20% and 2.21% with an average of 0.92%. Analysis of intraspecific genetic variations detected 5 different haplotypes and 15 variable sites with 5 parsimony informative sites. Haplotype diversity and nucleotide diversity values were 0.756 ± 0.130 and 0.00812 ± 0.00294 respectively. Analysis of phylogenetic and haplotype network revealed BGM 02-06 formed a specific haplotype that was separated from other haplotypes. Molecular markers for Asian redtail fish (H.nemurus) from the Progo River, Magelang, Central Java based on the 16S mitochondrial gene can use this specific haplotype.

Plants and microorganisms can coexist in such a way that each of these two heterospecific organisms benefit from this association. In the environment of plants there are several habitats of bacteria among them the phyllosphere which is the aerial part of the plant. The phyllosphere can be influenced by several factors including hydrocarbons. Thus, polycyclic aromatic hydrocarbons (PAHs) have been used to assess their influence on the phyllosphere microorganisms of the leaves of Gliricidia sepium. The results showed that the atmospheric concentrations of PAHs are rather high in rural areas. The spatial patterns of atmospheric concentrations of PAHs showed higher concentrations of naphthalene in the two experimental group due to the high road traffic. In the different experimental groups, 93626 and 96954 OTUs were identified in the leaves collected on the road (SR) and out of the road (SH), respectively. In this present study, the leaves harvested on the road which are more exposed to PAHs present a strongly elevated relative abundance of Actinobacteria and Bacilli. It can therefore easily deduce that these bacteria could have developed a kind of resistance to these road PAHs. On the other hand, bacteria belonging to the Alphaproteobacteria class are significantly less represented in this rural area.
