Juxtacortical mandibular chondrosarcoma during pregnancy : a case report
2017
Chondrosarcoma is one of the most common malignant bone tumors in adults. It use to affect upper arm, pelvis and thigh bone. A wide surgical extirpation represent the gold standard to treat this disorder. In fact, radiotherapy and chemotherapy are no useful. Interestingly, chondrosarcoma is rare in head and neck (HNCS) and extremely uncommon during pregnancy. Thus, there is a lack of evidence about the proper treatment in these cases. A wide surgical extirpation is also considered the most effective procedure in HNCS. There are no consistent evidences about the he role of radiation and chemotherapy. In view of that, the present study describes a case of juxtacortical mandibular chondrosarco…
Mechanical loading influences the lumbar intervertebral disc : A cross‐sectional study in 308 athletes and 71 controls
2021
There is evidence in animal populations that loading and exercise can positively impact the intervertebral disc (IVD). However, there is a paucity of information in humans. We examined the lumbar IVDs in 308 young athletes across six sporting groups (baseball, swimming, basketball, kendo, soccer and running; mean age 19yrs) and 71 non‐athletic controls. IVD status was quantified via the ratio of IVD to vertebral body height (IVD hypertrophy) and ratio of signal intensity in the nucleus to that in the annulus signal (IVD nucleus hydration) on sagittal T2‐weighted MRI. P‐values were adjusted via the false discovery rate method to mitigate false positives. In examining the whole collective, co…
Exercise for the intervertebral disc : a 6-month randomised controlled trial in chronic low back pain
2020
Background context Muscle, bone and tendon respond anabolically to mechanical forces. Whether the intervertebral disc (IVD) can benefit from exercise is unclear. Purpose To examine whether exercise can beneficially affect IVD characteristics. Study design/setting This is a single-blinded 6-month randomised controlled trial (ACTRN12615001270505) in an exercise and physiotherapy clinic. Patient sample Forty patients with chronic non-specific low back pain (NSCLBP) are included in this study. Outcome measures The primary outcome was lumbar IVD T2 time (MRI). Secondary outcomes included IVD diffusion coefficient and IVD expansion with short-duration lying. Methods Twenty patients progressively …
Characterization of Intervertebral Disc Changes in Asymptomatic Individuals with Distinct Physical Activity Histories Using Three Different Quantitat…
2020
(1) Background: Assessments of intervertebral disc (IVD) changes, and IVD tissue adaptations due to physical activity, for example, remains challenging. Newer magnetic resonance imaging techniques can quantify detailed features of the IVD, where T2-mapping and T2-weighted (T2w) and Dixon imaging are potential candidates. Yet, their relative utility has not been examined. The performances of these techniques were investigated to characterize IVD differences in asymptomatic individuals with distinct physical activity histories. (2) Methods: In total, 101 participants (54 women) aged 25&ndash
Hippocampal event-related potentials to pitch deviances in an auditory oddball situation in the cat: experiment I.
1995
Hippocampal event-related potentials (ERP) in the areas CA1, CA3, and dentate fascia (Df) were recorded in cats during an oddball situation when pitch deviant tones occurred in a series of standard tones. When difference waves were calculated by subtracting ERPs to the standard tones from those to the deviant tones, no clear N40d, corresponding to a cat analogue of the human mismatch negativity (MMN) observed in earlier studies, could be detected. Instead, a prominent later negativity (N130d) was observed. A possible extra-hippocampal source of the process reflected by the MMN-like negativity, and a relation between an orienting response (OR) and the N130d are discussed.
Poisto museokokoelmasta : museologinen arvokeskustelu kokoelmanhallinnan määrittäjänä
2016
This dissertation studies the issue of disposal in Finnish art museums. It is a research in the field of museology, in which museography plays a significant role. The field of museology functions as a science bridging theory and practice. In the research, museum collection management is divided into seven areas: acquisition, inventory, condition assessment, value assessment, conservation, upkeep and disposal. It is essential that collection management be viewed as a unified chain of operations, starting from acquisition and ending in disposal. This creates a bridge from the start of collection management to its end procedures, at which point the total disposal of an item is a possibility. A…
Music Therapy as an Effective Intervention in the Treatment of of Depression in a Patient With Korsakoff's Syndrome
2013
The main aim of this study is to demonstrate the efficacy of the Music Therapy intervention and the possibility of influencing positively on depressive symptoms of a patient with this Syndrome making significant improvements in the general condition and in particular on the “activation versus apathy". The Music Therapy approach is mainly based on a sonorous music relationship between the patient and music therapist. Active Music Therapy facilitates the expressive process, increasing communicative-relational abilities and modulation and regulation of emotions. This approach is based on intersubjective psychological theories and allows “affect attunement” moments. After 24 sessions of Music T…
The Effects of Nicotine on Music-Induced Emotion
2013
Nicotine is an available drug widely self-administered in the context of music (e.g. pubs, clubs). Furthermore, nicotine effects one’s physiology, which allowed us to test the effects of these physiological changes on the emotional experiences of music. We hypothesized that because nicotine changes one’s physiology it may also change one’s affective arousal in response to music. To test this, non-smokers were administered nicotine gum at either 2mg, 4mg, or placebo level. Participants then listened to 4 musical excerpts: happy, sad, neutral, and self-selected chill-inducing. After each listening, participants rated their emotional responses on 6 intensi-ty scales: arousal, pleasure, happy, …
Evaluating the Consonance and Pleasantness of Triads in Different Musical Context
2013
This study examines whether the consonance and pleasantness of triads (major, minor, augmented, and diminished) varies according to the musical context in which it is presented. The level of consonance and dissonance (C/D) of each chord when they were played alone without any musical contexts was judged. Following this, each chord was accommodated in a different position in a short cadence, and the level of C/D for each chord was judged. Additionally, the C/D and the pleasantness and unpleasantness (P/U) of the whole sequence were rated on a 7-point scale. The results show that, for major and minor triads, there was no significant difference in C/D levels between the ‘without musical contex…
The effects of synchronous music on patients undergoing magnetic resonance imaging
2016
Anxiety and claustrophobic reactions in Magnetic Resonance Imaging (MRI) lengthen the duration of examinations through increasing need of scan repetition, furthermore the need of anaesthesia makes the process costly. The sedative and alleviative effect of music is widely used in therapeutics, but in related research, music was only used with its original tempo as an intervention to reduce anxiety among MRI patients. 60 outpatients were examined in the Diagnostic Centre of Pécs to test whether the sedative effect of music can be improved by synchronizing it to the rhythm of the gradient pulsation, therefore reducing the effect of loud noises on the perception of music. The patients were assi…
