PURPOSE Management of endophthalmitis typically includes antibiotic combinations to arrest bacterial growth and antiinflammatory agents to limit inflammatory damage to sensitive tissues. Little research has been reported that systematically evaluates the contribution of each therapeutic component for treating infections caused by organisms of varying virulence. The authors determined the relati...

Role of the tectorial membrane revealed by otoacoustic emissions recorded from wild-type and transgenic Tecta ENT/ENT mice ABSTRACT Distortion product otoacoustic emissions (DPOAE) were recorded from wild-type mice and mutant Tecta ENT/ENT mice with detached tectorial membranes (TM), under combined ketamine/xylaxine anaesthesia. In Tecta ENT/ENT mice DPOAEs could be detected above the noise flo...

Context Human dentin powder (HD), bovine serum albumin (BSA) and endotoxin (LPS) may affect the antimicrobial activity of irrigating solutions. Aim To evaluate the inhibitory effect of HD powder, BSA, and LPS on the antibacterial activity of 0.5%, 1%, 2.5%, and 5% sodium hypochlorite (NaOCl), 2% chlorhexidine (CHX) gel, BioPure mixture of tetracycline, citric acid, and detergent (MTAD), and Q...

Beta-hemolysin production is a variable trait of the Lancefield group D streptococcus, Enterococcus faecalis. The E. faecalis hemolysin is encoded by large transmissible plasmids. The variable nature of this putative virulence factor provided an ideal system for testing its contribution in experimental endophthalmitis. In this study, isogenic E. faecalis strains were compared to determine wheth...

OBJECTIVE The antimicrobial activity of lactic acid (LA) alone or in combination with chlorhexidine (CHX) and cetrimide (CTR) against three Enterococcus faecalis strains, E. faecalis ATCC 29212, E. faecalis EF-D1 and E. faecalis U-1765, one Enterococcus durans strain and one dual-species biofilm was investigated. STUDY DESIGN The irrigating solutions tested were 20%, 15%, 10%, 5% and 2.5% LA,...

Abstract Aims A 2020 survey of undergraduate ENT education found there was wide variability between Medical Schools despite a standardised curriculum, published by UK. To improve this, group CTFs designed and led teaching sessions covering each aspect based on the UK curriculum. The aim to confidence in knowledge conditions expected at junior doctor level. Methods Final year students participat...

Mutants of Arabidopsis thaliana deficient in gibberellin synthesis (ga1-3 and ga1-6), and a gibberellin-insensitive mutant (gai) were compared to the wild-type (WT) Landsberg erecta line for flowering time and leaf number when grown in either short days (SD) or continuous light (CL). The ga1-3 mutant, which is severely defective in ent-kaurene synthesis because it lacks most of the GA1 gene, ne...
