MORPHOSTRUCTURAL ANALYSIS OF HUMAN DENTAL FOLLICULAR STEM CELLS ON HIGLY POROUS BONE HYDROXYAPATITE SCAFFOLD
2007
In this study we investigated the in vitro behaviour, morphostructure and extracellular matrix synthesis of human dental follicular stem cells (hDFSCs) isolated from human dental bud, which resulted to be positive for mesenchymal markers (CD29, CD90, CD146 and CD166) by FACS analysis. Cells were analysed by light and electronic microscopy to evaluate their biological response either at week 1, that is before differentiation, or at weeks 3-6, when they had been cultured in osteogenic medium onto a highly porous natural scaffold material (Bio-Oss). Microscopy analysis of primary culture cells showed they had a mesenchymal stem cell-like morphostructure, spindle shaped, similar to the culture …
Evaluation of alveolar cortical bone thickness and density for orthodontic mini-implant placement.
2013
Objective: Mini-implant stability is primarily related to bone quality and quantity. This study evaluated alveolar cortical bone thickness and density differences between interradicular sites at different levels from the alveolar crest, and assessed the differences between adolescents (12-18 years of age) and adults (19-50 years of age), males and females, upper and lower arch, anterior and posterior region of jaws and buccal and oral side. Study Design: In this retrospective study, 48 Computed Tomography scans, performed for oral surgery purposes were selected from dental records of 3,223 Caucasian orthodontic patients. The SimPlant software (Materialise, Leuven, Belgium) was used to measu…
Peri-Implant Behavior of Tissue Level Dental Implants with a Convergent Neck
2021
Introduction: The aim of this retrospective study was to analyze the radiographic peri-implant bone loss of bone level implants and tissue level implants with a convergent neck in screw-retained single crowns and in screw-retained fixed partial prostheses, after two years of functional loading. Materials and methods: The sample was divided into two groups according to their type: Group I: supracrestal implants with convergent transmucosal neck
Maxillary necrosis by mucormycosis : a case report and literature review
2007
The maxilla rarely undergoes necrosis due to its rich vascularity. Maxillary necrosis can occur due to bacterial infections such as osteomyelitis, viral infections such as herpes zoster or fungal infections such as mucormycosis, aspergillosis etc. Mucormycosis is an opportunistic fulminant fungal infection, which mainly infects immunocompromised patients. The infection begins in the nose and paranasal sinuses due to inhalation of fungal spores. The infection can spread to orbital and intracranial structures either by direct invasion or through the blood vessels. The fungus invades the arteries leading to thrombosis that subsequently causes necrosis of hard and soft tissues. We report a case…

Effects of Zoledronic Acid on Cathepsin K circulating levels in patients with bone metastasis.
2007
Cathepsin K serum levels were determinated in patients with bone metastases from breast cancer or prostate cancer in therapy with zoledronic acid or in patients or in patients with located breast or prostate cancer end in patients with non malignant diseases and in healthy blood. donors (control group). Cathepsin K serum levels were significantly more eleved in healthy subjects or in patients with peimary osteoporosis. Furthermore, the administration of Zoledronic acid to patients with metastatic bome disease from breast or prostate cancer, induced a marked increase of Cathepsin K serum levels.
“I Like to Keep my Archaeology Dead”. Alienation and Othering of the Past as an Ethical Problem
2019
As archaeologists, we have to deal with the dead, and as David Clarke once said, we like to keep our archaeology dead. From an epistemological perspective, alienation from the dead seems almost inevitable; otherwise, we would only project today’s conditions onto the past. Therefore, the past must be, and must remain, a foreign country. These alienating processes have ethical implications, however, especially when it comes to the study of human remains. In this article, we analyze the structures within the scientific discipline of archaeology that normalize practices, such as the labeling of human bone material during excavations and the object-like display of skeletons in museums. We argue …
Pacientu ar apakšstilba kaula lūzumu līdzestība aprūpē pēc ķirurģiskas vai neķirurģiskas ārstēšanas metodes
2018
Bakalaura darba tēma ir “Pacientu ar apakšstilba kaula lūzumu līdzestība aprūpē pēc ķirurģiskas vai neķirurģiskas ārstēšanas metodes”. Tēmas aktualitāti nosaka lūzumu statistika – 2016. gadā no visām Latvijā reģistrētajām traumām, visvairāk reģistrēti tieši lūzumi. Apakšstilba kaula lūzumi ir visai izplatīti – tie veido aptuveni 10% no visu kaulu lūzumiem. Pētījuma mērķis ir izpētīt pacientu ar apakšstilba kaula lūzumu līdzestību aprūpē pēc ķirurģiskas vai neķirurģiskas ārstēšanas metodes. Pētījuma uzdevumi ir izpētīt zinātnisko literatūru par apakšstilba kaula lūzumu un pacientu līdzestību ārstēšanās un atveseļošanās procesos. Raksturot Kalistas Rojas adaptācijas teoriju, un saistīt to ar …
