Clinical, radiological, surgical, and pathological determinants of olfactory groove schwannoma

Indian Journal of Neurosurgery, 2014
Background Olfactory groove schwannomas (OGS) are rare anterior cranial fossa base tumors with only 41 cases reported in literature. Olfactory ensheathing cell schwannoma (OECS) has similar clinico-radiological features as OGS, but a different cell of ...

Structural compression and entorhinal vulnerability: Linking tentorial adjacency to tau burden and dementia progression

Alzheimer's &Dementia, Volume 22, Issue 10, October 2026.
Abstract INTRODUCTION Early neurofibrillary tau degeneration in the entorhinal cortex (EC) is a hallmark of Alzheimer's disease (AD) and aging. We propose a biomechanical cascade hypothesis, suggesting proximity to the tentorial incisura (TI) may render the EC susceptible to chronic mechanical stress, potentially contributing to tau pathology.

World Trade Center neurotoxicant exposure severity is associated with cortical thinning and regional brain atrophy: a neuroimaging study of general responders at midlife

Alzheimer's &Dementia, Volume 22, Issue 10, October 2026.
Abstract INTRODUCTION Exposure to aerosolized pollutants is a risk factor for cognitive impairment and dementia, but the specific features of exposure‐related neurodegeneration remain unclear. METHODS We measured the World Trade Center Neurotoxicant Exposure Severity Index (WTC‐NESI) in 218 responders and unexposed controls aged 44‐65 years.

A detailed redescription of a skeletally immature ‘Redondasaurus’ suggests ontogenetic transformations in the taxon mirror phytosaurian morphological evolution

The Anatomical Record, Volume 309, Issue 10, Page 2656-2697, October 2026.
Abstract The study of morphological evolution is fundamentally tied to ontogeny, yet studies of these heterochronic processes in the fossil record are rare. Fossils belonging to an ontogenetic series are difficult to assign to an ontogenetic stage due to inconsistent proxies for skeletal ages, challenging to taxonomically assign due to morphological ...

Subventricular zone stem cells are heterogeneous with respect to their embryonic origins and neurogenic fates in the adult olfactory bulb [PDF]

, 2007
Wedetermined the embryonic origins of adult forebrain subventricular zone (SVZ) stem cells by Cre-lox fate mapping in transgenic mice. We found that all parts of the telencephalic neuroepithelium, including the medial ganglionic eminence and lateral ...

Experimental and field evidence indicate that islet‐nesting tundra birds experience reduced nest predation and benefit indirectly from high snow goose densities

Oikos, Volume 2026, Issue 10, October 2026.
Landscape features can shape the occurrence and strength of predator–prey interactions by influencing predation risk and prey distribution. In the High Arctic, some bird species select nesting sites with physical features that impede access for their main terrestrial predator, the Arctic fox.

Radiological Analysis of Olfactory Fossa Depth: A Tertiary Care Hospital Based Study

Birat Journal of Health Sciences, 2019
Introduction: Computed tomogram (CT) of nose and paranasal sinuses provides the detailed knowledge of depth of olfactory fossa as per Keros' classification, which is important in endoscopic sinus surgery. Objective: To analyze the types and frequency of depth of olfactory fossa in Nepalese population.

Cuttings, Combings, Fettlings and Flock: Gender and Australian Wool ‘Waste’, 1900–1950

Gender &History, Volume 38, Issue 3, Page 859-869, October 2026.
ABSTRACT As Australia's wool industry produced vast amounts of fine fleece from the nineteenth century, the wool processing and clothes manufacturing industries generated waste – products like cuttings, combings, fettlings and flock. Salvaged and then sold to waste merchants, these and other materials had a second life.

Variations of Anterior Skull Base Seen on Computed Tomography Scans of the Paranasal Sinuses

Journal of the Scientific Society
Context: The anterior skull base (ASB) and the paranasal sinuses are known for anatomical variations. Therefore, a preoperative assessment for the assessment of these variations is a necessity.
