Statistical shape modeling of the human inner ear through micro‐computed tomography imaging
In this study, 54 cadaveric temporal bone specimens underwent high‐resolution micro‐CT imaging. Images were semi‐automatically segmented and converted to 3D surface mesh models for morphological measurement and analysis. Statistical shape models were created for the inner ear, cochlea, and vestibular system, as well as for sex‐ and side‐based subgroups.

Ontogeny of murine bony semicircular canal form
Abstract The labyrinthine geometry and functional anatomy of the semicircular canals have intrigued scientists for decades, and there has been considerable interest in understanding how these complex structures grow and develop with evidence emerging from human studies that size maturation occurs exceptionally early by comparison with other systems ...

Multiple vortex vein ampulla varicosities [PDF]
Vortex vein ampulla varicosities are asymptomatic, harmless, findings in the retina. They are incidentally picked up on routine eye examination or when presenting for unrelated ocular symptoms. Clinicians and other eye care professionals unaware of this condition may be alarmed and may subject patients to unnecessary anxiety and expensive ...

Hyaluronan and Hyaluronidase, which is better for embryo development? [PDF]
Our aim was to examine size-specific effects of Hyaluronan (HA) on preimplantation embryo development. We investigated the effects of Hyalovet (HA, 500–750 kDa; the size produced by HA synthase-3, which is abundant in the oviduct), or HA treated with ...

Abstract Neandertals are known to possess very distinctive traits in their bony labyrinth morphology, such as an inferiorly positioned posterior canal and a very low number of turns in the cochlea. Hence, the inner ear has been often used to assess the Neandertal status of fragmentary fossils.

Common features between neoplastic and preneoplastic lesions of the biliary tract and the pancreas [PDF]
The bile duct system and pancreas show many similarities due to their anatomical proximity and common embryological origin. Consequently, preneoplastic and neoplastic lesions of the bile duct and pancreas share analogies in terms of molecular ...

Redescription of the Triassic cynodont Cistecynodon parvus and reassessment of its phylogeny
Abstract Cynodontia is an important subclade of Therapsida that first occurred in the late Permian. It includes extinct subclades which are the non‐mammaliaform cynodonts and Mammaliaformes, with the latter ultimately giving rise to crown mammals. The systematics of non‐mammaliaform cynodonts has been extensively studied and is relatively well‐resolved,

Ectopic pregnancy is a life-threatening condition affecting up to 2% of gestations. Implantation in the fallopian tube is most common, with symptoms typically presenting earlier for gestations in the ampulla and isthmus compared with the cornua and non ...

A Case of Concurrent Ampullary Adenoma and Gangliocytic Paraganglioma at the Minor Papilla Treated with Endoscopic Resection [PDF]
A gangliocytic paraganglioma is a benign tumor of the digestive system with a very low incidence. The tumor is histopathologically characterized by a triphasic pattern consisting of epithelioid, ganglion, and spindle-shaped Schwann cells.

Distal Urogenital Anatomy of Male Southern Coal Skinks, Plestiodon anthracinus pluvialis (Reptilia: Scincidae) [PDF]
I investigated the morphology and histology of the distal urogenital anatomy of male southern coal skinks (Plestiodon anthracinus pluvialis) from reproductively active individuals collected in Arkansas in order to provide comparative information with ...
