Enterococcus faecalis is a key contributor to persistent endodontic infections and often shows resistance to conventional medicaments such as calcium hydroxide. Growing antimicrobial resistance has led to interest in repurposing nonantibiotic drugs such as nonsteroidal anti-inflammatory drugs and proton-pump inhibitors that have shown promising antimicrobial effects against E. faecalis. The study aimed to evaluate the in vitro antibiofilm activity of different combinations of nonantimicrobial drugs with and without calcium hydroxide against E. faecalis. 2026-01-01T00:00:00Z http://irgu.unigoa.ac.in/drs/handle/unigoa/7800 Observation of limb abnormalities in Indirana chiravasi Padhye et al., 2014 from the Western Ghats region of Goa, India Rane, S.; Naik, S.; Karapurkar, J.; Sawant, N.S. 2026-01-01T00:00:00Z http://irgu.unigoa.ac.in/drs/handle/unigoa/7798 A baseline assessment of potentially toxic elements in smooth-coated otter (Lutrogale perspicillata) spraints from the estuarine landscape of Goa, India Dias, S.J.; D'Costa, J.; Ainkar, S.S.; Sinai-Borker, A.; D'Costa, A.H. Apex predators are effective indicators of bioaccumulation and biomagnification of xenobiotics. In this study, we determined the concentrations of eight potentially toxic elements (PTEs) (Pb, Cd, As, Cu, Zn, Mn, Fe, Cr) in the faeces (spraints) of smooth-coated otters (Lutrogale perspicillata) from the Mandovi-Zuari estuarine complex, Goa, India. Sampling was conducted at two locations: Study site-1 in the Mandovi estuary and Study site-2 in the Zuari estuary. Both rivers originate in the Western Ghats and are characterised by similar anthropogenic influences, including agriculture, urban expansion, and industrial activity. Three spraint samples were collected from each site and analysed for PTEs using Atomic Absorption Spectroscopy (AAS). The mean concentrations of PTEs (mg/kg d.w.) at study site-1 were as follows: Fe (365.4) greater than Zn (174.3) greater than Cu (38.5) greater than Mn (26.8) greater than Cr (21.4) greater than Pb (8) greater than Cd (2.3) greater than As (0.1). The mean concentrations of PTEs (mg/kg d.w.) at Study site-2 were as follows: Zn (167) greater than Fe (60.6) greater than Mn (45) greater than Cu (28) greater than Cr (20.2) greater than Pb (7.7) greater than Cd (2) greater than As (0.2). This study provides valuable preliminary insights into the exposure of L. perspicillata to PTEs in the estuarine landscape of Goa, India. 2026-01-01T00:00:00Z http://irgu.unigoa.ac.in/drs/handle/unigoa/7796 Field evaluation of bacterial wilt resistant lines and identification of promising bacterial wilt resistant varieties for Coastal region Ramesh, R.; D'Souza, M.; Asolkar, T.; Achari, G.; Gaitonde, S.; Thangam, M. Cultivation of brinjal in Coastal regions of India is severely affected by bacterial wilt disease caused by Ralstonia solanacearum. In this study, recombinant inbred lines were developed and screened for bacterial wilt resistance. Seventeen promising resistant lines were evaluated in the field for two years and the results indicated these lines were resistant to bacterial wilt. Lines 262-4, 5-12-1, 66-8-1, 205-1, 12-2-4 and 28-8-5 were promising among the purple types (0 to 4 percent wilt and yield 0.51 to 0.93 kg/ plant). Among the green types, lines 5-8-1, 93-8-1 and 92-3-7 were promising (0 to 5 percent wilt and yield 0.64 to 0.79 kg/ plant). Demonstration of eight lines in farmer's field indicated that lines 262-4, 5-12-1, 205-1, 5-8-1 and 12-2-4 were least infected (3 to 17 percent). Based on these studies, four purple lines 262-4, 5-12-1, 66-8-1 and 205-1 were released as bacterial wilt resistant brinjal varieties in the State of Goa. 2021-01-01T00:00:00Z
