The photodegradation of bifenthrin and deltamethrin was studied in the presence of Cu salts and two different solvents, methanol and acetonitrile. Results of the study showed that in the absence of any metal salt, the two pesticides degraded more rapidly in acetonitrile than in methanol. After 24 h of UV irradiation, 70% of deltamethrin had degraded in acetonitrile, while only 41% bifenthrin degraded in this solvent. In methanol, bifenthrin degraded at a much enhanced rate than in acetonitrile while the rate of degradation of deltamethrin was comparable to that in acetonitrile. The photodegradation was further enhanced by the addition of copper to the solution of bifenthrin and deltamethrin in acetonitrile. The rate of photodegradation of deltamethrin increased from 2.4 × 10 to 3.5 × 10 h in acetonitrile and 2.5 × 10 to 3.4 × 10 h in methanol after the addition of copper. Similarly, the rate of photodegradation of bifenthrin was increased from 5.0 × 10 to 9.0 × 10 h in acetonitrile and 7.0 × 10to 9.05 × 10 h in methanol with the addition of copper. Thus, copper has the potential to enhance the photodegradation of bifenthrin and deltamethrin in both the solvents.
Objectives: To compare the levels of N Terminal- ProBrain natriuretic peptide (NT-proBNP) and Troponin I (Trop I) to predict left ventricular ejection fraction (LVEF) in patients presenting with first ST-elevation myocardial infarction (STEMI).
Methodology: A cross-sectional study was carried out in Cardiology department of a tertiary care hospital from June to November 2021. A total of 150 patients who presented at emergency department with first STEMI and underwent primary percutaneous coronary intervention (PCI) were included. The patient’s second set of troponin I and NT-proBNP were collected during hospitalization. Echocardiography was done. Left ventricular function was assessed using modified Simpson’s method. For data analysis, SPSS 21 was used.
Results: The mean age was 60.60±11.1 years. There were 76% males, 53% hypertensive, 44% diabetic, 14% smokers with the most prominent type of myocardial infarction being anterior wall myocardial infarction accounting for 76.7%. Mean Trop I was 12.2±6.81 ng/ml, 9.5±8.63 ng/ml and 3.0±5.41 ng/ml for LVEF≤40%, 41-49% and >50% respectively while NT-proBNP was 7136.4±7.97pmol/l, 2328.9±3498.6pmol/l and 441±283.6pmol/l for LVEF ≤40%, 41-49%, and >50% respectively. We found a significant mean difference for Trop I (p=0.000) and NT-proBNP (p=0.0001). There was an inverse significant relationship of left ventricular ejection fraction with Trop I (r=-0.290, p=0.000) and NT- proBNP (r=-0.388, p=0.000).
Conclusion: In comparison to Troponin I, NT-proBNP serves as a better marker to predict LVEF in patients presenting with first STEMI.
Objective: To determine the impaired color function in pseudophakic background diabetic retinopathy patient
Methodology: After the ethical approval from The University of Faisalabad under ethical approval number TUF/Dean//2019/39 the cross-sectional study was conducted in the Ophthalmology department of Madina Teaching Hospital Faisalabad which is associated hospital of the The University of Faisalabad. 58 volunteers of both gender and age ranging between 35-75 years were studied through non-probability convenient sampling technique. Duration of study was September 2018 to February 2019. Visual acuity was tested from logmar at a 4 meter distance. Color vision was tested by conventional Farnsworth D15 test, along with slit-lamp and +70D lens to evaluate retinopathy severity, after proper consent of the patient. The test was performed after taking complete ocular, medical, surgical and drug history. Each pseudophakic eye was tested monocular and each subject was tested thrice.
Results: Results were analyzed using SPSS version 22. Significant association was seen between the color vision in pseudophakic diabetic patient with background retinopathy (p<0.05), using Pearson Chi-Square. Color vision by conventional D-15 showed mean of ±2.17 and standard error of ±1.05. While pseudophakic group showed mean of ±1.05 and standard error of ± 0.116.
Conclusion: There is color defect in pseudophakic diabetic with background retinopathy. The dyschromatopsia is more in the blue axis. Color vision defect (CVD) seen more in uncontrolled diabetic than controlled. Color vision defect (CVD) increases with the course of retinopathy. Color vision checking must be made an integral part of examination specifically in diabetic retinopathy patient.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
