The Effects of Chronic Cigarette Smoking on the Right Ventricular Functions in Healthy Young Male Subjects: A Speckle Tracking Echocardiographic Study
...Show More Authors

Background: Chronic cigarette smoking is one of the major risk factors for coronary artery disease. However, it has additional cardiac adverse effects independent of coronary atherosclerosis. Patient and Methods: After informed consent and perm- ission from the review board of the hospital, 80 healthy subjects who were classified as smokers or non-smokers were included in the study. They were examined by standard echocardiography protocol which was followed by two-dimensional speckle tracking to assess the functions of the right ventricle. Results: The tricuspid annular plane systolic excursion (TAPSE) was significantly reduced in smokers as compared to non-smokers (P < 0.05). The tricuspid flow peak late diastolic velocity (A wave) was significantly higher in smokers (P < 0.05, and hence the E/A ratio was signif- icantly lower (P < 0.05). The tissue Doppler imaging examination of right ventricular free wall showed that the peak systolic velocity of right ventricular (RV) free wall (S’), and the peak early diastolic velocity of RV free wall (E’) were significantly lower in smokers when compared to the control group (P < 0.05 for both). The global longit- udinal strain (GLS) assessed by 2D-speckle tracking echo- cardiography was also significantly reduced in smokers (P < 0.05). Conclusion: This study demonstrates that chronic cigarette smoking causes alterations in long-axis systolic and diast- olic functions of right ventricle in healthy young subjects. These changes can be detected early with 2-D speckle tracking echocardiography.

A Case Study of Potential Reasons of Increased Soil Phosphorus Levels in the Northeast United States
...Show More Authors

Recent phosphorus (P) pollution in the United States, mainly in Maine, has raised some severe concerns over the use of P fertilizer application rates in agriculture. Phosphorus is the second most limiting nutrient after nitrogen and has damaging impacts on crop yield if found to be deficient. Therefore, farmers tend to apply more P than is required to satisfy any P loss after its application at planting. Several important questions were raised in this study to improve P efficiency and reduce its pollution. The objective of this study was to find potential reasons for P pollution in water bodies despite a decrease in potato acreage. Historically, the potato was found to be responsible for P water contamination due to its high P sensitivity a
