    Abstract Objectives: The major challenges of the current century are the rapid changes in the climate, weather conditions and the environment. Governments, individuals, and societies need to work together to tackle the challenges posed to the environment in recent times. The literature highlights the urgent need to act however, little is known about public perception and their responsibilities. This study aimed to explore the public perception of the role of individuals, societies, and states in managing environmental challenges. Methods: In this cross-section study, a well-established English language questionnaire was developed. A total of 1000 questionnaires were distributed, and the response rate was 852 (85.2%). Among 852 participants, 488 (57.28 %) were males and 364 (42.72%) were females. The survey encompassed students 681 (80%), teachers 85 (10%); government officials 34 (4%), shop owners, merchants 25 (3%), doctors and engineers 17 (2%) and housewives 10 (1%). The questionnaires were analyzed, frequencies and percentages were calculated, and a p-value less than 0.05 was considered significant. Results: The results revealed that 621 (72.8%) of the individuals suggested that states adopt sustainable environmental policies; 639 (75%) of the respondents were in favor that individuals personally playing a role in tackling climate change; 699 (82%) agreed that there should be a bottom-up approach while dealing with the environmental problems. Moreover, 605 (71%) believed that the young generation is more inclined than the previous generation for global climate action, 542 (63.61 %) were in favor that civil society galvanized to enshrine environmental protection in the state constitution, and 554 (65%) suggested that national and international efforts cannot make a difference until and unless individuals don’t play a role in reducing the environmental pollution. The majority of the respondents were in favor of adopting the constructive approach to managing environmental challenges. Conclusions: These days the ...

    Abstract This study aimed to determine the impact on the lipid profile, carboxypeptidase N (CPN) and nitric oxide (NOx) associated with vitamin D (VD) status correction among Saudi adults with VD deficiency. A total 111 VD deficient (25(OH)D < 50 nmol/L)) adult Saudis aged 18–50 years old (57 females and 54 males) were enrolled in this 6-month interventional study. They were given 50,000 IU VD weekly for the first 2 months and then twice a month for the next 2 months, followed by 1000 IU daily for the last 2 months. The fasting lipid profile and the blood glucose, VD, NOx and CPN concentrations were measured at baseline and after intervention. Post-supplementation, the median VD was significantly higher ( p < 0.001) in females [58.3 (50.6–71.2)] and males [57.8 (51.0–71.8)]. HDL cholesterol significantly increased ( p = 0.05) and NOx significantly decreased ( p = 0.02) in males post-supplementation. Triglycerides were positively associated with NOx in all subjects before (r = 0.44, p = 0.01) and after (r = 0.37, p = 0.01) VD status correction. There was a significant increase in serum levels of CPN2 ( p = 0.02) in all subjects. Furthermore, CPN was inversely correlated with NOx (r = −0.35, p = 0.05) in males post-supplementation. In conclusion, VD status correction reduced serum NOx, particularly in males. The inhibition of NOx synthesis may be responsible for the anti-inflammatory effects of VD supplementation. An inverse association was found between NOx and CPN2.

    Abstract The Langendorff's isolated perfused small mammalian heart represents the optimal compromise in the conflict between the quantity and quality of data that can be acquired from an experimental model versus its clinical relevance, especially in relation to ischemia-reperfusion injury. We analyzed the important recent, as well as standard older articles to highlight the importance of Langendorff's isolated heart technique using the rat as an experimental animal model. The retrograde perfusion of isolated rat heart preparation is the most commonly used technique in cardiovascular research experiments with many advantages. The longevity of this preparation is one of the main advantages. From the moment an ex vivo preparation is established, it starts to deteriorate and the rate will depend on number of factors such as the skill of the operator, the species of animal, age, initial heart rate, choice and composition of the perfusion fluid, flow rate, presence or absence of various drugs, preload pressure, and the temperature at which the studies are carried out. Recently, various techniques and variables measured have undergone modifications. This review article has attempted to address many of the issues, developments, and applications which will assist investigators to make the best possible use of this experimental model using the rat.

    Abstract AIM: To investigate the effect of administration of agmatine (AGM) on gastric protection against ischemia reperfusion (I/R) injury. METHODS: Three groups of rats (6/group); sham, gastric I/R injury, and gastric I/R + AGM (100 mg/kg, i.p. given 15 min prior to gastric ischemia) were recruited. Gastric injury was conducted by ligating celiac artery for 30 min and reperfusion for another 30 min. Gastric tissues were histologically studied and immunostained with angiopoietin 1 (Ang-1) and Ang-2. Vascular endothelial growth factor (VEGF) and monocyte chemoattractant protein-1 (MCP-1) were measured in gastric tissue homogenate. To assess whether AKt/phosphatidyl inositol-3-kinase (PI3K) mediated the effect of AGM, an additional group was pretreated with Wortmannin (WM) (inhibitor of Akt/PI3K, 15 μg/kg, i.p.), prior to ischemic injury and AGM treatment, and examined histologically and immunostained. Another set of experiments was run to study vascular permeability of the stomach using Evan’s blue dye. RESULTS: AGM markedly reduced Evan’s blue dye extravasation (3.58 ± 0.975 μg/stomach vs 1.175 ± 0.374 μg/stomach, P < 0.05), and VEGF (36.87 ± 2.71 pg/100 mg protein vs 48.4 ± 6.53 pg/100 mg protein, P < 0.05) and MCP-1 tissue level (29.5 ± 7 pg/100 mg protein vs 41.17 ± 10.4 pg/100 mg protein, P < 0.01). It preserved gastric histology and reduced congestion. Ang-1 and Ang-2 immunostaining were reduced in stomach sections of AGM-treated animals. The administration of WM abolished the protective effects of AGM and extensive hemorrhage and ulcerations were seen. CONCLUSION: AGM protects the stomach against I/R injury by reducing vascular permeability and inflammation. This protection is possibly mediated by Akt/PI3K.

    Abstract Objectives: This study aimed to assess the impact of the Gross Domestic Product (GDP), spending on Research and Development (R&D), the number of universities and scientific journals on the published research documents, citable documents, citations per document and H-index in environmental sciences in the Middle East countries. Materials and Methods: All the 16 Middle East countries were included in the study. Information regarding the GDP, spending on R&D, the total number of universities and indexed journals was collected. Total number of research documents (papers), citable documents, citations per document and H-index in environmental sciences during the period 1996-2011 was recorded. The study used the World Bank, SCI-mago/Scopus, Web of Science, Journal Citation Reports (Thomson Reuters) as the main sources of information. Results: The mean GDP per capita of all the Middle East countries amounted to 18 125.49±5386.28 US$, spending on R&D was 0.63±0.28 US$, the number of universities equaled 36.56±11.33 and mean ISI indexed journals amounted to 8.25±3.93. The mean number of research documents published in environmental sciences in the Middle East countries during the period 1996-2011 was 2202.12±883.98; citable documents: 2156.87±865.09; citations per document: 8.74±0.73; and the H-index: 35.37±6.17. There was a positive correlation between the money spent on R&D and citations per documents (r = 0.6, p = 0.01), H-Index (r = 0.6, p = 0.01); the number of universities and a total of research documents (r = 0.65, p = 0.006), citable documents (r = 0.65, p = 0.006), H-Index (r = 0.50, p = 0.04), as well as ISI indexed journals and total research documents (r = 0.94, p = 0.0001), citable documents (r = 0.94, p = 0.0001), H-Index (r = 0.73, p = 0.001). Conclusions: The Middle East countries which spend more on R&D and which have a large number of universities and ISI indexed journals are likely to produce more significant volume of research papers in the field of environmental science.

    Abstract This study aimed to determine the effect of long term exposure to cement dust on lung function in non-smoking cement mill workers. This is a cross-sectional study of respiratory functions. Spirometry was performed in 100 apparently healthy volunteers; 50 non-smoking cement mill workers and 50 non-smoking un-exposed subjects. Based on the duration of exposure, cement mill workers were divided into three groups, less than 5, 5–10 and greater than 10 years. All subjects were individually matched for age, height, weight, and socioeconomic status. Pulmonary function test was performed by using an electronic spirometer. Significant reduction was observed in the mean values of Forced Vital Capacity (FVC), Forced Expiratory Volume in one second (FEV1), Peak Expiratory Flow (PEF) and Maximal Voluntary Ventilation in cement mill workers who had been working in the cement industry for more than 10 years compared to their matched un-exposed group. Lung functions in cement mill workers were significantly impaired and results show a long term duration response effect of years of exposure to cement dust on lung functions.

    Abstract OBJECTIVES: This study aimed to compare the impact of Gross Domestic Product (GDP) per capita, spending on Research and Development (R&D), number of universities, and Indexed Scientific Journals on total number of research documents (papers), citations per document and Hirsch index (H-index) in various science and social science subjects among Asian countries. MATERIALS AND METHODS: In this study, 40 Asian countries were included. The information regarding Asian countries, their GDP per capita, spending on R&D, total number of universities and indexed scientific journals were collected. We recorded the bibliometric indicators, including total number of research documents, citations per document and H-index in various science and social sciences subjects during the period 1996-2011. The main sources for information were World Bank, SCI-mago/Scopus and Web of Science; Thomson Reuters. RESULTS: The mean per capita GDP for all the Asian countries is 14448.31±2854.40 US$, yearly per capita spending on R&D 0.64±0.16 US$, number of universities 72.37±18.32 and mean number of ISI indexed journal per country is 17.97±7.35. The mean of research documents published in various science and social science subjects among all the Asian countries during the period 1996-2011 is 158086.92±69204.09; citations per document 8.67±0.48; and H-index 122.8±19.21. Spending on R&D, number of universities and indexed journals have a positive correlation with number of published documents, citations per document and H-index in various science and social science subjects. However, there was no association between the per capita GDP and research outcomes. CONCLUSION: The Asian countries who spend more on R&D have a large number of universities and scientific indexed journals produced more in research outcomes including total number of research publication, citations per documents and H-index in various science and social science subjects.
