Diverse Genetic Etiologies of Unilateral Polymicrogyria

open access: yesAnnals of Neurology, EarlyView.
Objective Polymicrogyria (PMG) is one of the most common human malformations of cortical development and is often classified by its radiographic pattern of distribution. Unilateral polymicrogyria (uPMG) is a subtype of PMG affecting a portion or all of one cerebral hemisphere.

Functional morphology of the pharyngeal teeth of the ocean sunfish, Mola mola

open access: yesThe Anatomical Record, EarlyView.
Abstract Many fish use a set of pharyngeal jaws in their throat to aid in prey capture and processing, particularly of large or complex prey. In this study—combining dissection, CT scanning, histology, and performance testing—we demonstrate a novel use of pharyngeal teeth in the ocean sunfish (Mola mola), a species for which pharyngeal jaw anatomy had ...

Serotonin and orthodontic tooth movement

open access: yesBiochimie, 2019
Peripheral serotonin continuously reveals its unexpected involvements in many organ functions. In bone tissue, there is an increasing evidence for a local serotonergic system affecting the cellular and molecular actors involved in bone turnover. During orthodontic treatment, tooth movement relies on bone remodeling, itself a result of the inflammatory ...

A perspective from the Mesozoic: Evolutionary changes of the mammalian skull and their influence on feeding efficiency and high‐frequency hearing

open access: yesThe Anatomical Record, EarlyView.
Abstract The complex evolutionary history behind modern mammalian chewing performance and hearing function is a result of several changes in the entire skeletomuscular system of the skull and lower jaw. Lately, exciting multifunctional 3D analytical methods and kinematic simulations of feeding functions in both modern and fossil mammals and their ...

Divergent functional traits in three sympatric Arctic charr Salvelinus alpinus morphs are not coupled with the age of the lineage divergence [PDF]

open access: yes, 2016
Three genetically discrete morphs of Arctic charr in Loch Rannoch, Scotland originated from a recent divergence within the lake (in situ) (piscivore and benthivore morphs) and from secondary contact of two older lineages (ex situ; a planktivore–piscivore/

In‐vitro puncture experiment using alligator teeth tracks the formation of dental microwear and its association with hardness of the diet

open access: yesThe Anatomical Record, EarlyView.
Abstract With the development of dental microwear texture analysis (DMTA), there has been an increasing application of DMTA for dietary estimation in extant and fossil reptiles, including dinosaurs. While numerous feeding experiments exist for herbivorous mammals, knowledge remains limited for carnivorous reptiles. This study aimed to qualitatively and

Preliminary report on the Myrmeleontidae (Neuroptera) of Paraguay [PDF]

open access: yes, 2010
Ten species of antlions are confirmed as present in Paraguay and seven additional species are suspected to be present there. All of the species are found also in Argentina and Brazil except for Eremoleon pulchra (Esben- Petersen) which is endemic to ...

Comparative and functional anatomy of masticatory muscles and bite force in opossums (Didelphimorphia, Didelphidae)

open access: yesThe Anatomical Record, EarlyView.
We describe the functional anatomy of masticatory muscles in nine opossums, finding a generalized anatomical pattern with differences related to skull morphology. Variation in quantitative myological data and estimated bite force was mostly related to size, and the increase in bite force supports dietary diversification associated with size increase ...
