Molariform Mesiodens in Primary Dentition

Case Reports in Dentistry, 2013
Mesiodens is a midline supernumerary tooth commonly seen in the maxillary arch, and incidence of molariform mesiodens in the maxillary midline is rare in permanent dentition and extremely uncommon in primary dentition.

Nance‐Horan Syndrome: Further Delineation of the Affected Male and the Female Carrier Phenotypes

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Nance‐Horan syndrome (NHS; OMIM 302350) is a rare, X‐linked syndrome characterized by bilateral congenital cataracts leading to profound vision loss, specific dental anomalies including characteristic screwdriver blade‐shaped incisors, facial anomalies, and intellectual disability.

Non‐RASopathy Genetic Syndromes Identified as the Molecular Cause of Disease in Patients Previously Diagnosed With Noonan Syndrome

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT Noonan Syndrome (NS) is a clinically and genetically heterogeneous condition characterized by typical facial dysmorphisms, short stature, congenital heart defects, and developmental delays. While variants in genes such as PTPN11, SOS1, and RAF1 account for most genetically confirmed cases, diagnosis is challenging due to phenotypic overlap ...

Genotypes and Phenotypes of Patients With TSPEAR‐Related Disorder: Evidence of a Predominant Dental Phenotype

American Journal of Medical Genetics Part A, EarlyView.
ABSTRACT TSPEAR (chr. 21q22.3) encodes a protein involved in tooth development and is predominantly expressed in the enamel knot. Biallelic loss of function variants in TSPEAR cause ectodermal dysplasia, tooth agenesis and sensorineural hearing loss. However, the role of TSPEAR in auditory processes is unclear.

A novel inhaled anesthesia technique for concurrent direct laryngoscopy in rats

Animal Models and Experimental Medicine, EarlyView.
Our novel nose cone anesthetic technique allows the use of gas anesthesia during concurrent direct laryngoscopy. Inhaled anesthesia not only has a better safety profile for rats, but also increases lab efficiency when compared to injectable anesthesia. Abstract The current anesthetic standard for laryngoscopy in rats utilizes injectable intraperitoneal

Recombinant Human Neuregulin1‐β1 Significantly Reduces Schwannoma Growth in Mice

Annals of Neurology, EarlyView.
rhNRGβ1‐Replacement‐Therapy: Under physiological conditions, NRGβ1 is expressed on axons (in orange), where it activates ERBB2 receptors, facilitating successful nerve regeneration following injury. However, loss of NF2 leads to a reduction in NRGβ1‐expression and increased ErbB2 levels on Schwann cells (in green), which contributes to schwannoma ...

Early synapsids neurosensory diversity revealed by CT and synchrotron scanning

The Anatomical Record, EarlyView.
Abstract Non‐mammaliaform synapsids (NMS) represent the closest relatives of today's mammals among the early amniotes. Exploring their brain and nervous system is key to understanding how mammals evolved. Here, using CT and Synchrotron scanning, we document for the first time three extreme cases of neurosensory and behavioral adaptations that probe ...

Finite element analysis of feeding in red and gray squirrels (Sciurus vulgaris and Sciurus carolinensis)

The Anatomical Record, EarlyView.
Abstract Invasive gray squirrels (Sciurus carolinensis) have replaced the native red squirrel (Sciurus vulgaris) across much of Great Britain over the last century. Several factors have been proposed to underlie this replacement, but here we investigated the potential for dietary competition in which gray squirrels have better feeding performance than ...

Bioimaging of sense organs and the central nervous system in extant fishes and reptiles in situ: A review

The Anatomical Record, EarlyView.
Bioimaging of the sense organs and brain of fishes and reptiles. Left panel: 3D reconstruction of the head and brain of the deep‐sea viperfish Chauliodus sloani following diceCT. Right panel: A 3D reconstruction of a 70‐day‐old embryo head of the bearded dragon Pogona vitticeps following diceCT, showing the position of the segmented brain within the ...

Tooth eruption status and bite force determine dental microwear texture gradients in albino rats (Rattus norvegicus forma domestica)

The Anatomical Record, EarlyView.
Abstract Dental microwear texture analysis (DMTA) is widely applied for inferring diet in vertebrates. Besides diet and ingesta properties, factors like wear stage and bite force may affect microwear formation, potentially leading to tooth position‐specific microwear patterns.
