The Superficial Glia Limitans of Mouse and Monkey Brain and Spinal Cord
ABSTRACT Using the double immunostaining method, the glia limitans on the surfaces of mouse and monkey brain and spinal cord were studied systematically. The results showed that the superficial glia limitans of mouse brain and spinal cord comprise a layer of surface astrocytes, while the glia limitans of monkey comprise a layer of foot‐plates from marginal regions as described in histology and neuroscience textbooks. These surface astrocytes first appear at embryonic day (E)16 in spinal cord and at E17 on the ventral surface of the brain. At postnatal day (P)1, a layer of astrocytes covered the outermost regions of the s...

Serial slice image segmentation of digital human based on adaptive geometric active contour tracking
Abstract: Segmentation is one of the crucial problems for the digital human research, as currently digital human datasets are manually segmented by experts with anatomy knowledge. Due to the thin slice thickness of digital human data, the static slices can be regarded as a sequence of temporal deformation of the same slice. This gives light to the method of object contour tracking for the segmentation task for the digital human data. In this paper, we present an adaptive geometric active contour tracking method, based on a feature image of object contour, to segment tissues in digital human data. The feature image is const...

Airway Morphology From High Resolution Computed Tomography in Healthy Subjects and Patients With Moderate Persistent Asthma
In this study, a commercial software package was used to segment the airway tree of seven healthy and six moderately persistent asthmatic patients from high resolution computed tomography images. The process was assessed with regards to the treatment of the images of the asthmatic group. The in vivo results for the bronchial length, diameter, WT, branching, and rotation angles are reported and compared per generation for different lobes. Furthermore, some popular mathematical relationships between these morphometric characteristics were examined in order to verify their validity for both groups. Our results suggest that, e...

Brain rewires itself after damage or injury, life scientists discover
When the brain's primary "learning center" is damaged, complex new neural circuits arise to compensate for the lost function, say life scientists from UCLA and Australia who have pinpointed the regions of the brain involved in creating those alternate pathways — often far from the damaged site. The research, conducted by UCLA's Michael Fanselow and Moriel Zelikowsky in collaboration with Bryce Vissel, a group leader of the neuroscience research program at Sydney's Garvan Institute of Medical Research, appears this week in the early online edition of the journal Proceedings of the National Academy of Sciences. ...

Ontogenetic patterns of morphological variation in the ectocranial human vault
ABSTRACT The skull is considered a modular structure in which different parts are influenced by different factors and, as a result, achieve adult shape at different ages. Previous studies have suggested that the basicranium presents a modular pattern that distinguishes sagittal and lateral parts, probably affected by the brain and masticatory structures, respectively. The vault of modern humans, in contrast, has been considered as a highly integrated system mainly influenced by brain growth. Here, we explored developmental shape variation in sagittal and lateral ectocranial vault in humans in order to assess if both region...

Comparison between endoscopic and microscopic stapes surgery
ConclusionEndoscopic surgery is particularly suitable for stapedial disease. Endoscopic stapes surgery can even be done in patients with a curved and narrow external auditory canal. Endoscopic surgery is also suitable for education: The surgical anatomy can be understood easily and both the surgeon and assistants can observe the procedure on the same monitor. However, it should only be performed by experienced surgeons because one‐handed manipulation is required and stereoscopic vision is not available. Level of Evidence3b.

Recent advances in endoscopic management of difficult bile duct stones
Endoscopic treatment is now recognized worldwide as the first‐line treatment for bile duct stones. Endoscopic sphincterotomy combined with basket and/or balloon catheter is generally carried out for stone extraction. However, some stones are refractory to treatment under certain circumstances, necessitating additional/other therapeutic modalities. Large bile duct stones are typically treated by mechanical lithotripsy. However, if this fails, laser or electrohydraulic lithotripsy (EHL) is carried out under the guidance of conventional mother‐baby cholangioscopy. More recently, direct cholangioscopy using an ultrathin ga...

Some unusual types of formation of the ansa cervicalis in humans and proposal of a new morphological classification
Ansa cervicalis (ansa hypoglossi) is a peripheral nerve structure—the primary choice for laryngeal reinnervation. Because the ansa formation is quite variable in humans, it is an object of a number of proposed classifications. Two interesting cases of formation of the ansa cervicalis were found during routine anatomical dissections. In the first case the unusual ansa had three basic roots—a superior one from the hypoglossal nerve, an aberrant middle root from the vagus nerve and an inferior root, coming from the cervical ventral branches. In the second case an ansa was described having roots from the vagus nerve and ce...

Furthermore, even during the development of neotenic salamanders such as axolotls, various larval muscles become indistinct, contradicting the commonly accepted view that during ontogeny the tendency is mostly toward the differentiation of muscles. We provide an updated comparison between these muscles and the muscles of other vertebrates, a discussion of the homologies and evolution, and show that the order in which the muscles appear during ...
