Imaginal leg and wing discs obtained from late-third-instar Drosophila larvae were cultured in vitro in various concentrations of ecdysterone ranging from 10(-10) to 10(-5) M in order to test the effect of hormone concentration on evagination and cell differentiation. At the optimal concentration of 8 x 10(-8) M discs evaginated normally, secreted the pupal cuticle, underwent apolysis, differen...
Oxfendazole is recommended as the drug of choice for treating porcine cysticercosis. The drug does not kill brain cysts and is not registered for use in pigs. Latest its safety in the recommended dose has been questioned. The aim of this study was to investigate two alternative anthelminthics. The efficacy of praziquantel and ivermectin was compared to oxfendazole In Vitro on Taenia solium. Cys...
BACKGROUND The pathophysiology underlying very late drug-eluting stent (DES) thrombosis is not sufficiently understood. Using optical coherence tomography, we investigated characteristics of very late stent thrombosis (VLST) according to different onset times. METHODS AND RESULTS A total of 98 patients from 10 South Korean hospitals who underwent optical coherence tomography for evaluation of...
Morphogenesis of photoreceptor outer segment disks appears to occur by an evagination of the ciliary plasma membrane (Steinberg et al., J Comp Neurol190:501-519, '80). We tested if polymerized actin (F-actin) was necessary for the regulation of this postulated process by incubating Xenopus eyecups with 5 or 25 pM cytochalasin D for 6-28 hours. During the second hour, the incubation medium conta...
talon cusp is a dental anomaly also known as an eagle’s talon. it is an extra cusp on an anterior tooth which arises as a result of evagination on the surface of a crown before calcification has occurred. the exact etiology is unknown. the incidence of talon cusp is less than 6%. commonly involved teeth are maxillary incisors, usually unilateral but in some instances bilateral. the classical ra...
The complete absence of eyes in the medaka fish mutation eyeless is the result of defective optic vesicle evagination. We show that the eyeless mutation is caused by an intronic insertion in the Rx3 homeobox gene resulting in a transcriptional repression of the locus that is rescued by injection of plasmid DNA containing the wild-type locus. Functional analysis reveals that Six3- and Pax6- depe...
Formation of membrane discs in photoreceptor cells requires evagination of its ciliary plasma membrane by an unknown molecular mechanism. Salinas et al. (2017. J. Cell Biol. https://doi.org/10.1083/jcb.201608081) show that peripherin (also known as peripherin-2 or peripherin-2/rds) diverts membrane traffic to photoreceptor disc formation by inhibiting ectosome release from the cilium.
