PRENATAL DEVELOPMENT OF TEMPORO-MANDIBULAR JOINTS: STATE OF ART

2017

The aim of this work is to analyze the state of the art of temporo-mandibular joint (MJ) to understand the varoius stage of the development of the same during embryogenesis. Various theories have been analyzed, such as the formation of apoptotic or the important role of growth factors, or the Valencia et studies in which are analyzed to numerous articular diseases in various stage of development. By the aforementioned studies show that many factors, of a different nature, are to be involved in the prenatal developlment of this important joint.

Hsp27 and Hsp60 in human submandibular salivary gland: Quantitative patterns in healthy and cancerous tissues with potential implications for differe…

2021

Tumors of the submandibular salivary gland (SMG) are uncommon but sufficiently frequent for the physician to consider them in routine examinations and for the pathologist to be prepared to differentiate them from other tissue abnormalities. However, scarcity of specimens makes training difficult, a situation compounded by the lack of accepted universal diagnostic guidelines. Furthermore, there is little information on the chaperone system (CS) of the gland, despite the increasing evidence of its participation in carcinogenesis as a biomarker for diagnosis and patient follow up, and in the mechanisms by which the tumor cells thrive. We are investigating this aspect of various tumors, and her…

ANP differentiates between primary Submandibular Gland Squamous Cell Carcinoma and Oral Squamous Cell Carcinoma: Preliminary data

2021

The natriuretic peptide system consists of three ligands, Atrial Natriuretic Peptide (ANP), Brain Natriuretic peptide (BNP) and C-type Natriuretic peptide (CNP), and three natriuretic peptide receptors (NPR’s), NPRA, NPRB and NPRC. We investigated the expression levels of NPPA (encoding ANP) and NPR1 (encoding NPRA, the main receptor for ANP) in primary benign (pleomorphic adenoma) and malignant (squamous cell carcinoma, SCC) submandibular salivary gland (SMG) tumors, as well as in primary oral squamous cell carcinoma (OSCC). We found that the NPPA and NPR1 expression levels were significantly different in SMG SCC versus OSCC, exhibiting a significant increase in NPPA and absence of NPR1 ex…

EFFECT OF AUTOLOGOUS PLATELET-RICH PLASMA ON DISTRACTION OSTEOGENESIS IN THE MANDIBLE OF RABBITS: A MORPHOLOGIC AND MORPHOMETRIC APPROACH

2013

Distraction osteogenesis of the jaws is a common surgical practice in the treatment of pediatric craniofacial deformities. Autologous platelet rich plasma (PRP) has been used to increase the healing potential of bones in humans during distraction osteogenesis. This article aims to study the morphometric and morphologic parameters resulting from the effect of PRP on bone healing after mandibular distraction in rabbits. Right mandibular distraction was performed in 12 rabbits divided equally into 2 groups. PRP and physiological saline were injected, according to a defined protocol, in the callus following distraction of the experimental and control groups respectively. The rabbits were sacrif…

An Online Multilingual Medical Vocabulary/Thesaurus/Dictionary (MED-VTD) for Facilitating Understanding of Medical Texts

Medical texts (e.g., reports and medicine leaflets) are usually written by professionals (physicians, medical researchers, etc.) who use their own language and communication style. On the other hand, they are often read by health consumers or other medical professionals who do not have the same vocabularies and can have difficulties in text comprehension. Thus, to help a generic user in understanding a medical text, it would be desirable to have an online medical vocabulary/thesaurus/dictionary that he/she can easily look for finding the plain equivalent of any medical (technical) term and a definition of the term with the same kind of language. In this work, we present an online multilingu…

Facilitating text understanding for e-learning users

2014

Web information on different disciplines (mainly technical ones) is mainly created by the different experts (engineers, scientists, physicians, lawyers, etc.) who use their own 'technical' language. On the other hand, this information is often read by general users who do not have the same skills and vocabularies of the experts and have difficulties to understand and learn it. In order to allow e-learners to use any document available on the web and understand it, it is desirable to have a system that takes a text written with technical terms and automatically translates it in a plain language and provides additional information with the same kind of language. In this work we present the me…

U-MedSearch: A Meta Search Engine of Medical Content for Different Users and Learning Needs

2015

More and more people use Internet to look for medical information for understanding and learning but different users, such as experts (e.g., physicians) and consumers (e.g., patients), have different needs and bring different levels of reading ability and prior knowledge. Generic and specific search engines and specialized health sites either do not exploit the whole web or overload users with information of different nature. On the contrary, it is important for a user to immediately find the information on the topic being explored that has the 'right' amount of information and level of complexity. This paper presents a meta search engine of medical information on the web, U-MedSearch, that…

Finding the best web medical content for different learner categories

2015

In the age of Internet where any kind of information can be easily found online, it is becoming increasingly evident that more and more people use the World Wide Web to seek health and medical information for understanding and learning. Different users have diverse needs, even when searching for the same topic. This is certainly true in healthcare, where a patient, a physician or a health executive might look for information on the same topic but have different necessities and bring different levels of reading ability and prior knowledge together with a different vocabulary. Generic search engines (like Google, Bing or Yahoo) work on the whole web but make generic searches often overloading…

A Ferrite Tubular Linear Motor (FTLM): Analysis and design

2015

The electromagnetic linear machines have wide applications in the electromagnetic aircraft launch systems [1] and in transportation systems [2]. Additional energy saving and efficiency can be achieved using a linear motor in the refrigeration application [3]. Linear electromagnetic machines are also very suitable for high-speed packaging, manufacturing sectors and precision positioning. There are different linear motor topologies. Tubular permanent-magnets are particularly attractive since they have a high thrust force density and high efficiency, no end windings, and zero net attractive force between stator and armature. There are various tubular motor topologies, in which the armature may…

Tubular composite scaffolds produced via Diffusion Induced Phase Separation (DIPS) as a shaping strategy for anterior cruciate ligaments reconstructi…

Injuries of tendons and ligaments are common, especially among the young population. Anterior cruciate ligament (ACL) injuries do not heal due to its limited vascularization and hence, surgical intervention is usually required. The ideal scaffold for ligament tissue engineering (TE) should be biocompatible and possess mechanical and functional characteristics comparable to the native ACL. The Diffusion Induced Phase Separation (DIPS) technique allows the preparation of homogenous porous tubular scaffold with micro-pores using a rather simple procedure. Composites based on biodegradable polymers and bioglass have attracted much attention in tissue reconstruction and repair because of their b…
