“The size of adult parasitoids is influenced by the quantity and quality of resources available during immature development. Gregarious development of endoparasitoids results in scramble competition where the resources are shared among individuals developing into the same host. Individuals that developed gregariously are therefore smaller and that reduced size generally translates into lower HM781-36B nmr fitness due to reductions in several life history traits including longevity, mobility and traits linked to reproduction. We measured the reproductive constraints induced by size in Anaphes listronoti (Hymenoptera: Mymaridae), a facultative gregarious egg parasitoid of Curculionidae. Size decreased with number of immatures developing in a host egg for both male and female A. listronoti. This reduction in size induced a reproductive cost as both males and females produced fewer gametes when developing gregariously. Contrarily to other egg parasitoids, A. listronoti males are not prospermatogenic and produced
some sperm during their adult life. Their spermatogeny index is estimated at 0.6-0.7 that places this species as moderately synspermatogenic. Female A. listronoti have an ovigeny index of 0.70 and are therefore moderately synovigenic. Large females that developed singly received a full sperm complement only when mated by a large male that also developed singly. When mating with a small triplet male, a NU7441 large female received less than half her sperm complement. Large males were able to mate three females before the number of sperm transferred started to decrease. Crown Copyright (C) 2012 Published by Elsevier Ltd. All rights reserved.”
“Background/aim The aim of this study is to report a reduction in the thickness of the ganglion cell complex (GCC)
after vitrectomy with internal limiting membrane (ILM) peeling in eyes with idiopathic macular hole (MH). Methods Twenty-eight consecutive eyes with an idiopathic MH treated by vitrectomy with ILM peeling were studied. All eyes VS-6063 mouse had an intravitreal injection of indocyanine green to make the ILM more visible. The best-corrected visual acuity (BCVA), GCC thickness measured by spectral domain optical coherence tomography, and retinal sensitivity measured by microperimetry were determined before and at 3 and 6 months after the vitrectomy. Results The MH in all eyes was closed after the initial surgery. The BCVA was significantly improved at 3 and 6 months (P<0.001 and P<0.001, respectively). The thickness of the GCC was significantly reduced at 3 and 6 months postoperatively (P<0.001 and P<0.001, respectively). The GCC thickness was significantly correlated with the retinal sensitivity in the central 10 degrees at 6 months (r=0.55, P=0.
