Abstract	Removal of heavy metals by the invasive alien weed greater club rush (Scirpus grossus L. f) in a wetland ecosystem was estimated and compared with water hyacinth (Eichhornia crassipes) to assess its efficiency as a phytoremediator. The study was conducted during October-December 2016 by collecting soil and plant samples from an industrially polluted locality in Thiruvananthapuram district, Kerala. Results showed that in both the species, the metal concentration was more in the root system than in the shoot portion. Total metal uptake pattern in greater club rush was Cu>Cr>Zn>Ni>Pb>Co>Cd>As, while in water hyacinth it was Cu>Zn>Ni>Cr>Pb>Co>As>Cd. It was concluded that greater club rush with its huge biomass production (>30 t/ha), could remove many of the heavy metals from contaminated soils more efficiently than water hyacinth. Biological concentration factor (BCF), translocation factor (TF) and biological accumulation coefficient (BAC) calculated for assessment of heavy metal mobility also suggested that greater club rush has the potential to be utilised for phytoremediation of contaminated soils.

Abstract	Background and Aim: Acute liver failure is associated with high mortality and only about 40% patients survive without liver transplantation. The available prognostic models failed to predict the outcome correctly. Here, we aimed to determine if alpha-fetoprotein (AFP) can be used as a prognostic marker in acute liver failure. Materials and Methods: For this prospective observational study, sixty patients with the diagnosis of acute liver failure were allocated and serum AFP ratio was measured on days 1 and 3 of admission. AFP ratio was calculated as day 3 AFP/day 1 AFP value. Other laboratory parameters and various etiological factors of acute liver failure were also studied. Results: The average AFP ratio among survivors was 1.77 ± 0.94 and among patients who died, the average ratio was 0.68 ± 0.58. Hence, AFP ratio is an important prognostic tool in predicting mortality with a P < 0.001. Majority of patients (80.6%) of patients whose AFP ratio was <0.7 died while majority of patients whose AFP ratio was >0.7 survived (70.4%). Hence, we concluded that AFP values change dynamically during the course of acute liver failure and AFP ratio can be used as a prognostic marker in acute liver failure. AFP ratio showed statistically significant negative correlation with prothrombin time and international normalized ratio, serum globulin, and the levels of indirect bilirubin, especially on the third day after admission and the variables were significantly elevated in the patients who died. Conclusions: AFP ratio can be used as a predictor of mortality in acute liver failure patients. Higher the ratio more are the chances of survival.

Abstract	Background: Dental education is relatively complex, demanding and a unique pedagogical procedure. The purpose of this study was to determine dental student's perception of the learning environment and to determine the learning barriers among dental students in a private college located in Guntur district, Andhra Pradesh. Materials and Methods: The source of the data includes 306 dental under-graduate students, from academic years 1-4. There are divided into two groups i.e. 159 pre-clinical students and 147 clinical students. They were posed with a validated structured questionnaire, which includes 28 closed ended questions along with questions on 3 different domains i.e. administrative, academic and environmental learning barriers. Results: The overall response rate is 100%. At the administrative level, maximum number of students identified that there was poor academic guidance for the students during courses registration given and there are inadequate extra-curricular activities for the students such as conferences, workshops and seminars. At academic level, 20.6% dental students proposed that questions in the exam are depending on memorising rather than understanding and analysing. 12.2% of the clinical students stated that there was lack of appropriate teaching strategies of the lecturers which are acting as learning barriers. As environmental factors, most of the students agree that inadequate number of computers and the unavailability of internet connection, unavailability of entertainment facilities that motivate the learning process and that the laboratories aren't equipped in terms of space and equipment's for training which would affect the learning process. Conclusion: This study has emphasized on the factors which requires improvement with respect to student's perspective. These learning barriers are to be noted by the educational institutions and the required modifications are done in the infrastructure as well as in the curriculum proposed to the students. Better dental education will instill ...

Abstract	The present study was undertaken to assess the nutritive value of greater club rush (Scirpus grossus L. f) and safety of the weed biomass as a livestock feed. The results showed that the nutrient composition of the weed biomass was comparable to some of the popular cultivated fodder crops like guinea grass. Heavy metal content of the sedge plant was mostly within the permissible limits as recommended by World Health Organisation (WHO). However, the cadmium concentration was found to be more than the safe limit, indicating possible risk in allowing free grazing in contaminated soils. The data on the transfer and accumulation of heavy metals from soils to plant shoots/roots as estimated through biological concentration factor (BCF), translocation factor (TF) and bio accumulation coefficient (BAC) also indicated that there is a need for caution when animals are allowed to graze freely on the luxuriant growth of greater club rush in wetland ecosystem.

Abstract	The chemical and pharmacological activity of the compound 1-benzylimidazole was analysed using vibrational, NMR and UV-Visible spectroscopic tools. The necessary data were obtained by recording FT-IR, FT-Raman, NMR and UV-Visible spectra. 1H and 13C NMR spectral chemical shifts were observed and investigated to understand the basis of the antiparasitic, antifungal and antimicrobial activities. The elaborate electronic excitational absorptions in which bathochromic shifts in the UV-Visible spectrum are linked to strong cardiotonic activity are noteworthy. The pharmacodynamic activity was related to the molecular polarization as analysed according to different analytical parameters. The molecular reactivity was studied according to the dislocation of charge levels in frontier molecular orbitals. NBO analysis was carried out to delineate the asymmetric charge interaction transitions among orbitals, which were correlated with the pharmacological behaviour of the compound. The enantiomer errors in the electronic structure have been analysed by simulating ECD and VCD spectra.

Abstract	The mounting tide of bovine mastitis by methicillin-resistant Staphylococcus aureus (MRSA) poses serious threat to efficacy of antibiotic treatment. Therefore, plant derived essential oils and their constituents are gaining great importance in the recent times as promising antimicrobial agents. Hence the present study was conducted to evaluate antibacterial activity of lemongrass oil (LGO) and its active principle, citral against methicillin and oxacillin resistant Staphylococcus aureus (MRSA) isolated from bovine mastitis cases. Among the 16 S. aureus organisms isolated, six isolates identified as MRSA by antibiogram against methicillin and oxacillin were selected for further study. The findings of the study indicated significant antimicrobial activity of LGO and citral as evident from their minimum inhibitory concentration (MIC) and diameter of zone of inhibition values.

Abstract	Introduction: Molar incisor hypomineralization (MIH) describes the clinical picture of hypomineralization of systemic origin affecting one or more first permanent molar. There is a rarity of prevalence studies in Indian population. Objectives: The main aim of this study was to investigate the prevalence of MIH in a population of South Indian children. Settings and Design: A cross-sectional epidemiological survey, included 2000 children aged 11-16 years chosen by stratified random sampling from government and private schools of Davangere, a city in South India. Materials and Methods: Evaluation of MIH and decayed, missing and filled teeth was carried out in these children by a calibrated examiner. The severity of hypomineralization was recorded according to the Wetzel and Reckel scale. Statistical Analysis: Chi-square test was used to analyze the categorical data. P ≤ 0.05 was considered for statistical significance. Results: About 8.9% of all examined children showed at least one ill-structured first permanent molar in terms of MIH. The male and female ratio was found to be 1:1.1. The decreasing order of occurrence of MIH affected teeth were permanent maxillary molars, maxillaryincisors, mandibular molars and the mandibular incisors. Conclusion: The prevalence of MIH in the permanent dentition of south Indian children was 8.9%. There is a need for a proper planned preventive and restorative program with regard to the increasing prevalence of MIH.
