Abstract
Background: Different models are used to explore the underlying cellular and molecular mechanism of lung disease especially pulmonary vascular disease but most of the experiments were performed on animal models with little evidence available from humans. Objective: The aim of this study is to provide a baseline optimal resting tension (ORT) value for performing experiments on human pulmonary artery rings and strips. Methods: After REC approval, tissue samples were collected from lung surgery patients. Total 20 PA rings of internal diameter 2-4 mm and 2 mm long were prepared and mounted under physiological conditions in organ bath system and myograph. After equilibration at 1g basal tension, 40mM KCl induced active tension (AT) recorded. Samples washed for 30 minutes and repeated twice at 1g to confirm reproducibility. Further experiments performed at 1.2g, 1.4g, 1.6g, 1.8g and 2g basal tension and KCl induced AT recorded. Results: In human pulmonary artery rings increasing the basal tension from 1.0 g to 1.6 g significantly augmented the 40mM KCl induced active tension. Increasing the active tension from 1.6 g to 2.0 g either decreased or plateaued the 40mM KCl induced response. Both organ bath and myograph shows similar result and confirmed that optimal RT for human pulmonary artery rings to be 1.61 g. The optimal resting tension in our experiment was 1.61 g for pulmonary artery ring. Conclusion: More studies are needed to validate this data and also to identify if the optimal resting tension is different in different size pulmonary arteries.

Abstract
Purpose: To assess compliance with and awareness about oral anticoagulant therapy (OAT) among Saudi patients, and their willingness to use the point-of-care (POC) INR testing devices for self- monitoring. Methods: A cross-sectional study was conducted in the anticoagulation clinic at King Khalid University Hospital (KKUH) in Riyadh, Saudi Arabia over the period of six months.A face-to-face interview questionnaire was carried out for all patients fulfilling the inclusion criteria and analysed according to: demographics, adherence, knowledge, and INR control. Compliance and knowledge were assessed based on Morisky 8-item medication adherence scale and the oral anticoagulation knowledge test (OAK) respectively. Comparison between knowledge, adherence and INR range with demographics was conducted. Results: Most of the respondents were on warfarin (89.5%). Generally, Patients had poor knowledge and medium adherence (53.1%) with OAT predominantly among the elderly. (24%) of the Poor Knowledge group (PKG) were high adherent participants compared to (14.5%) of the Fine Knowledge Group (FKG). However, (53.2%) of FKG had a controlled INR where this percentage falls into (27%) in the PKG, with a significant difference between the two regarding their INR range (p=0.001). Majority of patients (74.7%) were eager to make use of the POC-INR devices. Conclusion: Patients had poor knowledge about OAT, but most of them were highly adherent compared to the FKG. However, significant difference was noted in INR control where the FKG had controlled INR more than the PKG. Our results show that the level of knowledge didn’t affect the degree of compliance, but educational programs would definitely help patients in having less complication, less visits to the clinics and improve their routine in general. The majority of Patients were accepting to the idea of using the POC-INR devices, which will help them in keeping the INR within the therapeutic range, and potentially reducing adverse clinical outcomes.

Abstract
Air Pollution, especially fine particles (PM 2.5) has been an important issue in Taiwan recently, especially in the three biggest cities, Taipei, Taichung and Kaohsiung. This study focused on the association between air pollutants concentrations (data from Taiwan Environmental Protection Administration (EPA)) and cardiovascular mortality (data from Taiwan Death Registry (TDR) provided by the Department of Health (DOH)). Concentration of fine particle is Kaohsiung>Taichung>Taipei (Daily average in 2006-2009: 46.84, 35.59, 30.11; Taiwan 34.61). Taichung, with moderate weather, appears to have most notable long-term effect of fine particle on cardiovascular disease death, which is especially evident in the cold season (Relative risk of Taichung: 1.06 in warm season, 1.34 in cold season; Taiwan: 0.98 in warm season, 1.02 in cold season). The long-term effect of fine particle on hypertensive disease and cerebrovascular disease is notably obvious in cold season in Taichung (Relative risk: hypertensive disease 1.47, cerebrovascular disease 1.36 in cold seasons; hypertensive disease 0.95, cerebrovascular disease 1.03 in warm seasons). On the other hand, short-term effects of fine particle on hypertensive disease are most evident (Odds Ratio: 1.89 in cold season). The long-term effect of fine particle on cardiovascular disease death is very obvious in the city Taichung. Seasonal effects in the cold season seem to worsen the situation. We also take the difference in composition of the fine particles in the three cities into consideration. Future work will include co-effects between weather and composition in different cities on the issue of fine particle effects on cardiovascular disease.

Abstract
Study Objective: The aim of this study was to develop a method of assessing cardiovascular function (heart rate (HR), cardiac output (CO), blood pressure (BP)) in response to deep breathing, standing maneuver and handgrip exercise, using a Finometer. Subjects: Twenty subjects (10 males and 10 females) were healthy, young mean age 24.4 years males and 26.7 years females, non-obese mean ± SD of BMI was 23.4±7.4, 22.8±4.5 males and females respectively. Methods: Beat to beat heat rate and blood pressure variability were monitored during deep breathing test, posture change to standing position and handgrip exercise using a Finometer. This involves a finger cuff pressure which placed in the middle left finger and arm cuff pressure on the upper left arm. Then, automatic calibration was made followed by recording of baseline measurements for 3 minutes and then physiological maneuvers were performed starting with deep breathing (2 minutes), standing (2 minutes) and handgrip exercise at 20%, 40% of MVC (2min) and 60% of MVC (1 minute). This event separated by time for recovery (15min) as well as (3min) baseline measurements before each physiological maneuver. Results: A significant increased and decreased in cardiovascular parameter during inspiration and expiration in both gender respectively (p<0.05). Orthostatic maneuver caused a significant reduction in systolic blood pressure and cardiac output whereas HR (p<0.05) and DBP (P>0.05) increased in both genders. Cardiovascular parameters showed a significant increased during handgrip exercise at 40% and 60% of MVC but not during 20% of MVC. Discussion: Cardiovascular changes during inspiration and expiration caused a stimulation or inhibition of pulmonary stretch receptors respectively; this was companied with changes of abdominal and intra-thoracic pressures. This was confirmed in the study, a significant reduction (P≤0.05) of the parameters during inspiration and increased (P≤0.05) during expiration which completely driven by parasympathetic nervous system. Posture maneuver causes blood pooling to the lower part of the body lead to decrease of cardiac output and venous return which stimulated the sympathetic and inhibited parasympathetic nervous system which in turn causes an increases of heart rate to maintain a reduction of blood pressure. A significant increase of cardiovascular parameters (P≤0.05) during handgrip exercise at 40% and 60% of MVC and this was due to stimulation of sympathetic discharge and inhibition of vagal tone as well as peripheral reflexes which originated from exercising muscle. Gender differences in responses to autonomic stress tests might be related to several factors such as body size, muscle mass and sex hormone. Overall, a variability of cardiovascular parameters during physiological maneuvers reflected the integrity and effectiveness of neuro-cardiovascular control. This will apply on the patients suffering from diabetic neuropathy and therefore developed a method to evaluate the autonomic nervous disorders.

Abstract
We report the first case of infective endocarditis caused by Paenibacillus provencensis, a very rare gram-positive spore-forming rod. A mitral valve vegetation was incidentally discovered by intra-operative transoesophageal echocardiography in a 70-year old lady undergoing aortic valve replacement. Empirical antibiotic treatment for infective endocarditis with gentamicin and teicoplanin was started. The precise identification of the causative agent relied on genotypic characterisation with 16S rDNA gene sequencing. Microbiologic culture was subsequently performed to obtain the antimicrobial susceptibility profile and adjusted the antibiotic regimen accordingly. The patient was treated with a four weeks course of vancomycin and meropenem, followed by a further two weeks of daptomycin due to the identification of vancomycin-resistant enterococci in a rectal swab. After a long in-hospital stay, the patient eventually recovered clinically and biochemically and transthoracic echocardiogram demonstrated a well-functioning mitral valve without residual lesions from the endocarditis. This is, to the best of our knowledge, the first report showing that Paenibacillus provencensis can be a pathogen in humans and that a member of the genus Paenibacillus may be involved in native valve endocarditis. This case also emphasises the importance of 16S rDNA gene sequencing by real-time polymerase chain reaction, as a rapid and accurate method to identify microorganisms, like Paenibacillus, which can be missed by conventional microbiology investigations.

Abstract
Objective: The role of job stress as a risk factor for chronic disease has been in debate. Several investigators argue in support of a causal connection while others remain controversial. The job stress in Iran and its relationship with cardiovascular diseases has not been focused on many scientific studies. This study was conducted to investigate health aspects of stressful work on cardiovascular disease risk factors. Method: This prospective cohort study was carried out on 227 male employees from 2010 to 2012. The Farsi version of Siegrist's ERI questionnaire was employed to measure job stress. Medical examination including height, weight, blood pressure and lipid profile were collected at pre-employment, baseline and 3 times in a 6-months interval. A two-level linear regression model was applied to CVD risk factors as outcome to evaluate the effect of job stress. Result: Median age was 30, mean scores of effort, reward, and over commitment were 10.7(SD=3.6), 41.4(SD=9.2), 14.1(SD=2.6) at baseline. Adjusted results for shift work, smoking, pre-employment height, weight, glucose, triglyceride, cholesterol, SBP and DBP showed age as a significant predictor of longitudinal change in BMI, SBP, DBP, LDL, total cholesterol; reward only predictor of BMI(β=-.01, p=0.012, 95% CI: -0.02, .002); effort predictors of LDL(β=-3.7, p=0.026, 95% CI: -6.9, -.44) and HDL(β=0.3, p=0.004, 95% CI:0.10, 0.51), and over commitment a predictor of HDL(β=-0.45, p=0.003, 95% CI:-0.75,-0.15). Conclusion: Components of job stress targeted some of CVD risk factors, reward only predictor BMI, effort predictors of LDL and HDL, over commitment a predictor of HDL, and age is a longitudinal predictor.
