Imaging of Temporomandibular Joint: Approach by Direct Volume Rendering
2014
Background: The purpose of this study was to conduct a morphological analysis of the temporomandibular joint, a highly specialized synovial joint that permits movement and function of the mandible. Materials and Methods: We have studied the temporom-andibular joint anatomy, directly on the living, from 3D images obtained by medical imaging Computed Tomography and Nuclear Magnetic Resonance acquisition, and subsequent re-engineering techniques 3D Surface Rendering and Volume Rendering. Data were analysed with the goal of being able to isolate, identify and distinguish the anatomical structures of the joint, and get the largest possible number of information utilizing software for post-proces…
Anatomy of the cervical spine
2015
The vertebral column, or spine, consisting of a coordinated series of 33-34 vertebrae separated from each other by intervertebral disks, is divided in five segments or sections: cervical, dorsal, lumbar, sacral and coccygeal [1-7]. Not available
Lymphatic vessels of the dura mater: a new discovery?
2015
Aspelund et al. discover the presence of a lymphatic vessel network in the dura mater of the mouse brain and show that these dural lymphatic vessels are important for the clearance of macromolecules from the brain.
Type V collagen counteracts osteo-differentiation of human mesenchymal stem cells
2014
In search of novel gene signatures for osteo-differentiation of mesenchymal stem cells (MSCs), we submitted cDNA preparations from undifferentiated and differentiating MSCs to differential display- and semiquantitative-PCR and found down-regulation of COL5A1 in osteo-induced cultures at days 21 and 28, when the mineralized matrix accumulates. We also cultured osteo-differentiating MSCs onto type V collagen substrates and found a decrease in the accumulation of extracellular calcium compared to those grown in uncoated flasks. To our knowledge, this is first evidence that type V collagen might represent a stromal component that impairs osteogenesis.
The arterial blood supply of the temporomandibular joint: an anatomical study and clinical implications
2013
Purpose: The aim of this study was to analyze three-dimensional images of the arterial supply to the temporomandibular joint. Materials and Methods: Ten patients (five men and five women, mean age 36 years) without signs or symptoms of temporomandibular disorders, who underwent contrast-enhanced computed tomographic (CT) scanning with intravenous contrast, were studied. The direct volume rendering technique of CT images was used, and a data set of images to visualize the vasculature of the human temporomandibular joint in three dimensions was created. After elaboration of the data through post-processing, the arterial supply of the temporomandibular joint was studied. Results: The analysis …

Adipokines in obesity and metabolic diseases
2020
Adipose tissue secretes many adipokines that regulate important physiological functions. Growing studies have highlighted that these bioactive molecules may contribute to the development of metabolic and cardiovascular diseases. Adipokines exert systemic metabolic effects and independent activity on numerous cells of the cardiovascular system, including cardiomyocytes and vascular cell walls. Adiponectin shows anti-inflammatory and anti-atherosclerotic activity on blood vessels. Conversely, resistin is endowed with pro-inflammatory effects and stimulates the proliferation of smooth muscle cells, thus promoting the development of atherosclerotic plaque. Leptin plays an important role in card…
Selection of the best three oocytes for intracytoplasmic sperm injection (ICSI) using apoptotic analysis of cumulus cells
2009
Introduction: We studied the apoptosis rate of the cumulus cells of individual cumulus-oocyte complex (COC), to verify a relationship with clinical outcomes, in terms of pregnancy and implantation rates. Usually oocytes are selected using morphological criteria. We tried to verify if cumulus cell apoptotic rate could be used as a molecular criteria in selecting oocytes with higher implantation potentiality. Material and Methods: The study design consisted in two different trials: in the first we investigated apoptosis rate in cumulus cells of the three selected oocytes, according to Italian law, to be fertilized by intracytoplasmic sperm injection (ICSI). In a second trial, average apoptosi…
