Application of Ozone Therapy in the Conservative Surgical Treatment of Osteonecrosis of the Jaw: Preliminary Results
2019
The main goals of the management of osteonecrosis of the jaw (ONJ) are to slow the progressionof the disease and, when it is achievable, to remove all the necrotic bone promoting the tissues’healing [...]
Alveolar distraction osteogenesis for dental implant treatments of the vertical bone atrophy : a systematic review
2019
Background To determine if alveolar vertical distraction osteogenesis obtains better results compared to other bone regeneration treatments (guided bone regeneration with membranes and / or filling material, or autogenous bone graft) in terms of bone gain, complications, and implant survival and success rates. Material and Methods An electronic search was performed in Pubmed (MEDLINE), Cochrane Library and Scopus databases in March 2017. Besides, a manual search was carried out. Inclusion criteria were randomized controlled trials published within the last 10 years with at least 1 year of follow-up after implant placement. No language restriction was applied. Exclusion criteria were studies…
Surgical and orthodontic rapid palatal expansion in adults using a modified palatal partial osteotomy technique (ppot): Technique description and cli…
2020
Transversal hypoplasia of the upper maxilla is a frequent condition between malocclusions. The rapid maxillary expansion (RME) is an already consolidated technique for these types of defects. This case report analyzes the outcome of a novel surgical technique that we named TOPP (Partial Palatal osteotomy technique) aiming to provide scientifically proven data over the percentage of relapse and the long-term stability of this type of surgical assisted palatal expansion. A 24 year old male patient with a hyperdivergent class III, presenting the absence of 1.1 due to a teenage trauma and a transversal contraction of the upper arch was selected for the surgery. The mucoperiosteal flap was perfo…
Optimized culture conditions for tissue explants of uterine leiomyoma
2012
Background Uterine leiomyomas are the most common benign tumours in women, which arise from smooth muscle cells of the uterine myometrium and usually are multicentric. In spite of their frequency pathogenesis is widely unknown, mainly due to the absence of a suitable model system. We describe the systematic optimization of culturing leiomyoma tissue explants in an economical and effective ex vivo system. Methods Different concentrations of oxygen, different media, sera, hormones, and growth factor supplements were tested. Immunohistochemical stainings with antibodies against hormone receptors as well as specifying proliferation and apoptotic indices and real-time PCR were performed. Results…
Cell-Free Fetal DNA and Non-Invasive Prenatal Diagnosis of Chromosomopathies and Pediatric Monogenic Diseases: A Critical Appraisal and Medicolegal R…
2022
Cell-free fetal DNA (cffDNA) analysis is a non-invasive prenatal diagnostic test with a fundamental role for the screening of chromosomic or monogenic pathologies of the fetus. Its administration is performed by fetal DNA detection in the mother’s blood from the fourth week of gestation. Given the great interest regarding its validation as a diagnostic tool, the authors have set out to undertake a critical appraisal based on a wide-ranging narrative review of 45 total studies centered around such techniques. Both chromosomopathies and monogenic diseases were taken into account and systematically discussed and elucidated. Not surprisingly, cell-free fetal DNA analysis for screening purposes …
Hippocampal theta phase-contingent memory retrieval in delay and trace eyeblink conditioning
2017
Hippocampal theta oscillations (3–12 Hz) play a prominent role in learning. It has been suggested that encoding and retrieval of memories are supported by different phases of the theta cycle. Our previous study on trace eyeblink conditioning in rabbits suggests that the timing of the conditioned stimulus (CS) in relation to theta phase affects encoding but not retrieval of the memory trace. Here, we directly tested the effects of hippocampal theta phase on memory retrieval in two experiments conducted on adult female New Zealand White rabbits. In Experiment 1, animals were trained in trace eyeblink conditioning followed by extinction, and memory retrieval was tested by presenting the CS at …

Freemium pelialan hinnoittelumallina
2013
Kaaronen, Olli Freemium pelialan hinnoittelumallina Jyväskylä: Jyväskylän yliopisto, 2012, 24 s. Tietojärjestelmätiede, kandidaatintutkielma Ohjaaja: Ojala, Arto Mobiilipelaamisen lisääntyminen on johtanut pelialalla perinteisten liiketoimintamallien väistymiseen ja uusien ansaintamallien kehittymiseen. Tämä kirjallisuuskatsauksena toteutettu tutkielma käsittelee mobiilipelialalla käytettyä freemium-hinnoittelumallia ja sen variaatioita. Tutkielmassa esitetään myös pelitoimialan aikaisempia liiketoimintamalleja. Tutkimustuloksena todetaan, että mobiilipelien suosio on vaikuttamassa pelitoimialan valtasuhteisiin, sillä pelien jakelun ja markkinoinnin siirtyminen digitaaliseen muotoon syö suu…
La mobilità liberalizzata: molto rumore per nulla?
