Introduction: The genus Exiguobacterium includes psychrotrophic, mesophilic, and moderate thermophilic strains and species that have been isolated from extreme environments, including very cold or hot environments. The genus Exiguobacterium has received much attention in biotechnology, and related industries due to secretory enzymes with high enzymatic activity and consequently stable enzymes capable of tolerating extreme conditions. The aim of the present study was to introduce and describe the phenotypic and the genotypic characterization of a novel species of genus Exiguobacterium isolated from the Ilam mountains, Iran. Materials and Methods: Genotypic features were analyzed using universal genes (gyrB, hsp70, rpoB, and citC) belonging to the Exiguobacterium genus. Also, cspC1, nusA and dnaJ genes were used to confirm the profile of new psychrotrophic strains. The distinctive phenotypic characteristics of the new strain with the most famous strains of the genus Exiguobacterium were investigated. All statistical analyses were conducted using R packages for data visualization and exploratory data. Results: A motile, Gram-stain-positive, rod-shaped, non-sporing, tolerant up to 5% NaCl, grew at 0-25  ° C and pH 6 and 9, designated Exiguobacterium sp. HA2 was isolated from the soil. The major isoprenoid quinone is MK-7 and in the smaller amount are MK-6 and MK-8. The major cellular fatty acids (>10 %) were isoC13: 0, isoC15: 0 and C16: 0. To adapt to low temperatures, Exiguobacterium sp. HA2 upregulated expresses cold shock response including cold shock protein (CSP) and transcription elongation protein NusA. Also, downregulated expression of heat shock protein DnaJ domain protein. Conclusions: In the current study we investigated the difference in the genotype, phenotypic, and functional characteristics of Exiguobacterium sp. HA2. It can be regarded as representing a novel psychrotrophic species within the genus Exiguobacterium.

Air quality in the residential areas adjacent to the industrial regions is of great concern due to the association with particulate matter and toxic gaseous which has adverse effects on human health. Therefore, the present study aimed to investigate the air quality in term of PM10 concentrations and toxic gaseous (CO and NO) at University Hussein Onn Malaysia (UTHM) residential college which is adjacent to a wood processing, electronic and fibre board factories. Four Stations defined as Station 1 (KKM), Station 2 (KKP), Station 3 (KKTDI) and Station 4 (KKTU) were selected for this investigation. PM10 concentrations were measured using the E-Sampler Particulate Matter for 24 hours period within the dry season (February – May 2016) which was associated with the heavily haze phenomenon in Malaysia. The distribution of selected toxic gases in UTHM student hostels was determined using the TSI IAQ (CO) and Dragger X-am 7000 (NO). PM10 and toxic gaseous levels were compared to the Ambient Air Quality Standard (AAQS) and to compute the assumption of the sources of PM10 by using Open Air R Package Software. Data were analysed using the R Software and packages (Open-air, BRT, Akima). The highest concentration of PM10 was 114 μ g/m3 recorded at KKTDI followed by 58 μ g/m3 at KKP. The maximum CO concentrations noted at KKP (1. 8 ppm). However, both PM10 and CO concentrations not exceeded the AAQS of 150 μ g/m3 and 30 ppm respectively. Moreover, concentrations of NO at KKP (0. 61 ppm) and KKM (2. 18 ppm) exceeded the AAQS (0. 17 ppm) indicating the possibility of presence health risk for students at UTHM due to poor air quality. The air quality is directly associated to level of energy consumption which causes climate changes and accumulation of greenhouse gases.

Objective(s): Respiratory diseases affect patients' quality of life, but various, accessible and understandable education such as infographics, can play a major role in preventing these diseases, improving patients' quality of life, and reducing costs. The aim of this study was developing the informational packages for respiratory patients by infographic method. Methods: Informational packages for respiratory patients were prepared by infographics using a qualitative method. The four stages of study included: 1) identifying common respiratory patients based on prevalence,2) providing appropriate scientific contents,3) developing the infographics,and 4) providing the final content, face validity of Infographics. Data analysis and evaluation was performed simultaneously with data collection and during the infographic design process. For the accuracy of the data, face, content and the structure of infographics, pulmonologists, medical library and information science specialists, technology and medical informatics specialists, and respiratory patients were examined. Results: According to the hospital's health information system and interviews with patients, six respiratory diseases or related symptoms were identified, including: shortness of breath, pneumonia, pulmonary edema, respiratory distress, asthma, and bronchitis and two types of visual and textual infographics were designed for each. Conclusion: With professional cooperation between medical librarians and clinical specialists to prepare health informational packages, it is possible to increase the awareness of patients and save the time of the clinical team to provide information to patients.
