Influence of Storage Containers and Seed Pelleting on Seed Quality in Brinjal (Solanum melongena L.) during Storage

The experiment was conducted using brinjal hybrid seeds cv. Arka Navneet. Seeds were pelleted with Bavistin, ZnSO4, MnSO4, DAP and Arappu leaf powder and stored in paper and polyethylene bags under ambient conditions for 12 months. Among the seed pelleting treatments, seeds pelleted with Bavistin (0.1%) followed by Albezia amara leaf powder (250 g/kg) resulted in minimum quantitative losses with better seed quality parameters. The seeds stored in polyethylene (700 gauges) bags maintained better seed quality parameters with less quantitative losses in comparison with seeds stored in paper bags throughout the storage period. In the interaction, effect of seeds pelleted with Bavistin and stored in polyethylene bag followed by Albezia amara leaf powder and stored in polyethylene bag revealed higher values for all the positive quality parameters when compared to other interaction effects throughout the storage period

DNA fragmentation index and its correlation with other sperm parameters in 4833 infertile males

Background: Semen analysis forms the basic investigation for male factor of infertility. According to WHO Manual sperm values of normalcy are decreasing. Recent studies have highlighted newer parameters of sperm playing their role in the outcome of pregnancy. The aim was to study the DNA fragmentation index (DFI) and to know its correlation with other sperm parameters.Methods: A total of 4833 cases underwent routine semen analysis along with the DFI. The statistical analysis was done using SPSS using t test and ANOVA test.Results: It was observed that 52% infertile males presented late for treatment. All parameters showed a decline with advancing age. There was definite correlation between sperm count and sperm motility as well as morphology. The DFI showed significant negative correlation with sperm count. Pearson correlation showed positive correlation between DFI and sperm motility and morphology.Conclusions: The study highlights the need for increasing awareness about male factor of infertility. A thorough semen analysis along with DFI can help the clinician to explain the couple in a better way about the choice of ART and success of treatment

Evaluation of validity and reliability of multiple-choice questions in second MBBS competency-based medical education-based pharmacology examination of medical institute of India

Background: Multiple choice questions (MCQs) are most commonly used assessment tool in undergraduate medical examination. Assessment method must be reliable and valid. To improve quality of MCQs, item analysis was carried out by determining their validity and reliability using parameters like difficulty index, discrimination index, distractor efficiency and Cronbach’s alpha value.Methods: Study was carried out among 193 second year medical students. Each student was given 40 MCQs of 1 mark each. After assessment of MCQs, validity of test was analyzed by using difficulty index, discrimination index and distractor efficiency while reliability was analyzed by using Cronbach’s alpha.Results: Mean ± SD of difficulty index, discrimination index, functioning and non-functioning distractors were 59.80±23.38, 0.25±0.12, 1.98±0.92 and 13.25±13.05 respectively with reliability value of 0.7. About 47.5% items had moderate difficulty index, 22.5% items have excellent discrimination index with 35% items having 100% distractor efficiency. Reliability of test as measured by Cronbach’s alpha value was 0.7. There was weak correlation between difficulty index and discrimination index.Conclusions: It is concluded from study that given MCQs test have reliability but not validity and needs to improve quality of MCQs. Validity of test is improved by improving difficulty index, discrimination index, distractor efficiency of items

Cardiovascular profile of patients with chronic kidney disease

Background: Frequency of fatal and nonfatal cardiovascular events increase even in early stages of chronic kidney disease (CKD). This study was aimed to understand the cardiovascular profile of patients with CKD.Methods: This observational study was conducted on patients who were admitted with chronic kidney disease in Sri Venkateswara Rama Narayan RUIA Government General Hospital, Tirupati. Patients were classified according to their severity of CKD. All patients had an electrocardiogram and echocardiogram. Results of various biochemical investigations, electrocardiogram and echocardiogram were compared between patients with mild, moderate and severe CKD.Results: Combined diabetes mellitus and hypertension was found to be the most common case of CKD in Authors patient population (43%), followed by diabetes mellitus alone (37%). Serum creatinine and blood urea nitrogen were found to be significantly higher and creatinine clearance and haemoglobin were significantly lower among patients with severe CKD. Electrocardiography revealed 50% had left ventricular hypertrophy (LVH), 30% had tall ‘T’ waves and 15 % had ST-segment changes. Mean inter-ventricular septal end diastole thickness and mean left ventricular mass was found to be significantly in patients with severe CKD as compared to mild CKD.Conclusions: Extensive cardiovascular evaluation of patients with CKD is warranted even if the classical symptoms are not absent and early cardiovascular rehabilitation should be instituted in such patients

Sonochemical Formation of Peracetic Acid in Batch Reactor: Process Intensification and Kinetic Study

The present chapter highlights the kinetic studies for the sonochemical synthesis of peracetic acid (PAA) in a batch reactor. The effect of different operating parameters including acetic acid to hydrogen peroxide molar ratio, temperature, catalyst loading, effect of ultrasound, were studied using Amberlite IR-120H as a catalyst. The deactivation of the Amberlite IR-120H catalyst has also been studied. The experimental data were further utilized for the estimation of intrinsic reaction rate constants and equilibrium constants. From the experimental results; the optimized PAA concentration was observed for 471 mg/cm3 catalyst loading at 40°C with acetic acid to hydrogen peroxide molar ratio equals to 1:1 in the presence of ultrasound. Results also revealed that the reaction rate was found to be significantly enhanced in the presence of ultrasound, which can be attributed to the enhanced mixing and in-situ formation of H2O2. The use of ultrasound drastically reduces the overall reaction time to 60 min, which is very less compared to 30 h as reported for conventional batch reactor utilizing H2O2 only
