Case Report: Diagnosis of Petrous Apex IgG4-Related Disease by Middle Cranial Fossa Craniotomy and Temporal Bone Biopsy

open access: yesFrontiers in Neurology, 2022
IntroductionPrimary IgG4-related disease (IgG4-RD) of the temporal bone is a rare condition. Unlike typical petrous apicitis or Gradenigo syndrome, our patient presented exclusively with unilateral cranial nerve VI palsy and symptoms of diplopia.

Osteoclastoma of temporal bone

open access: yesIndian Journal of Otolaryngology and Head and Neck Surgery, 2003
A 20 year male presented with a gradually increasing painless swelling at right temporal region with progressive hearing loss conductive in type. On plain X-ray-a wide radio translucent area of bone destruction was noted. The mass was excised as much as possible via post-auricular incision extending antiriorly toward the zygomatic root ...

Day/night variations of myeloid and lymphoid cell subsets in the murine inguinal lymph node

open access: yesFEBS Open Bio, EarlyView.
The circadian system is involved in the temporal regulation of the immune system. Our study reveals that two innate immune populations, NKT cells and neutrophils, predominate at the beginning of the day in healthy mice, highlighting how the time of day influences immune responses.

Spatio-temporal structure of cell distribution in cortical Bone Multicellular Units: a mathematical model

open access: yes, 2010
Bone remodelling maintains the functionality of skeletal tissue by locally coordinating bone-resorbing cells (osteoclasts) and bone-forming cells (osteoblasts) in the form of Bone Multicellular Units (BMUs). Understanding the emergence of such structured

Digital reconstruction of the Ceprano calvarium (Italy), and implications for its interpretation [PDF]

open access: yes, 2017
The Ceprano calvarium was discovered in fragments on March 1994 near the town of Ceprano in southern Latium (Italy), embedded in Middle Pleistocene layers. After reconstruction, its morphological features suggests that the specimen belongs to an archaic

The potential protective effects of temporal bone pneumatization: A shock absorber in temporal bone fracture.

open access: yesPLoS ONE, 2019
ObjectivesWe hypothesize that when temporal bone fractures occur, the pneumatic cells in the temporal bone are able to absorb most of the impact force during a traumatic event.

Pioglitazone plus (−)‐epigallocatechin gallate: a novel approach to enhance osteogenic performance in aged bone marrow mesenchymal stem cells

open access: yesFEBS Open Bio, EarlyView.
Aged human bmMSCs are seeded in the scaffold. Osteoblastic induction can slightly increase cell's bone‐forming activity to produce bone‐like tissues, shown as the sporadic xylenol orange‐stained spots (the lower left image). Notably, pioglitazone plus EGCG co‐treatment dramatically increases cell's bone‐forming activity and bone‐like tissue production (

Towards a New Spatial Representation of Bone Remodeling [PDF]

open access: yes, 2012
Irregular bone remodeling is associated with a number of bone diseases such as osteoporosis and multiple myeloma. Computational and mathematical modeling can aid in therapy and treatment as well as understanding fundamental biology.

MDCT of Dehiscent or Thin Bone Coverage over the Superior Semicircular Canal: Assessment of Prevalence by Age and Contralateral Canal Bone Thickness

open access: yesGenel Tıp Dergisi, 2023
Objective: Superior semicircular canal dehiscence (SSCD) describes the presence of a defect in the superior bone coverage of the membranous SSC. The etiology of the defect is not known and its reported CT prevalence is variable.

The role of lipid metabolism in neuronal senescence

open access: yesFEBS Open Bio, EarlyView.
Disrupted lipid metabolism, through alterations in lipid species or lipid droplet accumulation, can drive neuronal senescence. However, lipid dyshomeostasis can also occur alongside neuronal senescence, further amplifying tissue damage. Delineating how lipid‐induced senescence emerges in neurons and glial cells, and how it contributes to ageing and ...
