The morphological characteristics of the eyes and the retinae of lanternfish larvae of Lampanyctus crocodilus, Benthosema glaciale, and Myctophum punctatum were analyzed in pre-flexion, flexion, and post-flexion stages. Pre-flexion larvae of L. crocodilus, the species with the shallowest depth distribution, had spherical eyes located antero-laterally on a strongly laterally-compressed head, sug...

1 2 The development of the visual system in anamniotic vertebrates is a continual process, 3 allowing for ontogenetic changes in retinal topography and spatial resolving power. We 4 examine the number and distribution of retinal ganglion cells in wholemounted retinae 5 throughout the protracted embryonic development (approx. five months) of a chondrichthyan, 6 the brown banded bamboo shark, Chi...

introduction: tanacetum sonbolii (asteraceae) is an endemic species in iran. in the present study, we examined the effects of tanacetum sonbolii hydroalcoholic extract on the formalin test in mice. methods: 126 swiss albino mice weighing 230-280g were used as subjects. the formalin test was performed on two control groups (marked as intact and saline groups n = 6 in each group) and an experimen...

BACKGROUND Sporadic Alzheimer's Disease (SAD) is caused by genetic risk factors, aging and oxidative stresses. The herbal extract of Rosa canina (R. canina), Tanacetum vulgare (T. vulgare) and Urtica dioica (U. dioica) has a beneficial role in aging, as an anti-inflammatory and anti-oxidative agent. In this study, the neuroprotective effects of this herbal extract in the rat model of SAD was in...

Environmental factors can lead individuals down different developmental pathways giving rise to distinct phenotypes (phenotypic plasticity). The production of winged or unwinged morphs in aphids is an example of two alternative developmental pathways. Dispersal is paramount in aphids that often have a metapopulation structure, where local subpopulations frequently go extinct, such as the specia...
