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
Extracellular Vesicle microRNAs Contribute to the Osteogenic Inhibition of Mesenchymal Stem Cells in Multiple Myeloma
2020
Osteolytic bone disease is the major complication associated with the progression of multiple myeloma (MM). Recently, extracellular vesicles (EVs) have emerged as mediators of MM-associated bone disease by inhibiting the osteogenic differentiation of human mesenchymal stem cells (hMSCs). Here, we investigated a correlation between the EV-mediated osteogenic inhibition and MM vesicle content, focusing on miRNAs. By the use of a MicroRNA Card, we identified a pool of miRNAs, highly expressed in EVs, from MM cell line (MM1.S EVs), expression of which was confirmed in EVs from bone marrow (BM) plasma of patients affected by smoldering myeloma (SMM) and MM. Notably,we found that miR-129-5p, whic…
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.
Osteonecrosis of the jaw as an adverse bisphosphonate event: Three cases of bone metastatic prostate cancer patients treated with zoledronic acid
2007
Bisphosphonates offer a significant improvement in the quality of life for cancer patients; these potent inhibitors of bone resorption have been shown to markedly reduce the morbidity frequently resulting from bone metastases. Despite the success of bisphosphonates as therapeutic agents, however, toxicity in the form of osteonecrosis of the jaw (ONJ) is a rare complication whose incidence rate has climbed in recent years. ONJ is defined as an unexpected development of necrotic bone in the oral cavity, and is commonly associated with administration of the bisphosphonates Pamidronate and Zoledronate. Clinical features include local pain, soft-tissue swelling, and/or loose teeth; ONJ is also o…
“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 …
Audzēkņu instrumentspēles prasmju un ķermeņa darbības pilnveides mijsakarības trombona spēles mācību procesā mūzikas skolā
2015
Trombona spēles pedagoģija bieži vien izmanto paņēmienus un metodes, kas ir pretrunā ar cilvēka ķermeņa darbības fizioloģiskajiem principiem un var gan kavēt un ierobežot instrumentspēles prasmju attīstību, gan radīt kaitējumus mūziķa veselībai. Ārvalstu mūzikas pedagoģijas zinātniskajā literatūrā arvien lielāks uzsvars tiek likts uz cilvēka darbības psiholoģisko un fizioloģisko mehānismu un likumsakarību integrēšanu pedagoģiskajā procesā. Arī trombona spēles prasmju pilnveidi nepieciešams balstīt cilvēka ķermeņa darbības pamatprincipos. Mērķis: izpētīt trombona spēles prasmju pilnveides teorētiskos aspektus un izstrādāt ķermeņa darbības psihofizioloģiskajos pamatprincipos balstītu vingrinā…
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 …
