Tämän sivuaineen tutkielman tarkoituksena on selvittää, miten suomalaiset ja italialaiset englannin kielen opiskelijat tunnistavat englanninkielisten idiomien merkityksiä. Erityisesti opiskelijoiden oman äidinkielen vaikutusta idiomien ymmärtämiseen tutkitaan, kuin myös idiomien eri ominaisuuksien vaikutusta. Lisäksi tutkitaan, miten opiskelijat itse ajattelevat osaavansa käyttää idiomeja, ja pitävätkö he idiomien oppimista tärkeänä. Tutkielmaan osallistui 35 suomalaista englannin kielen yliopisto-opiskelijaa ja 34 italialaista englannin kielen yliopisto-opiskelijaa. Tutkimusaineisto kerättiin monivalintakyselyn avulla. Idiomit valittiin Collins Cobuild Dictionary of Idioms (2001) -sanakirjasta. Kysely sisälsi 36 idiomia, jotka valittiin kolmesta eri frekvenssiluokasta. Jokaisesta frekvenssiluokasta valittiin neljä idiomia, joille oli vastine sekä suomen että italian kielessä, neljä idiomia, joille oli vastine vain suomen kielessä ja neljä idiomia, joille oli vastine vain italian kielessä. Kullekin idiomille oli annettu neljä merkitysvaihtoehtoa, ja näistä yksi tai kaksi oli sanakirjojen mukaisia oikeita vastauksia. Tutkimuksen tulokset näyttävät osoittavan, että sekä suomalaisilla että italialaisilla oli vaikeuksia idiomien merkitysten tunnistamisessa. Kuitenkin myös suomalaisten ja italiaisten välillä oli tilastollisesti merkittävä ero. Suomalaiset osasivat idiomit huomattavasti paremmin kuin italialaiset. Koehenkilöt ymmärsivät merkittävästi helpommin idiomit joille oli vastine heidän omassa äidinkielessään kuin idiomit joille ei ollut vastinetta. Lisäksi vastaajat näyttivät hyötyvän myös idiomien kuvainnollisen ja kirjaimellisen merkityksen läheisyydestä eli läpinäkyvyydestä. Idiomien frekvenssi sen sijaan ei näyttänyt vaikuttavan niiden ymmärtämiseen. Suomalaisten ja italialaisten englannin opiskelijoiden mukaan idiomien opiskelu on hyödyllistä ja tarpeellista. Tulokset osoittavat, että idiomien ymmärtäminen on haastavaa jopa edistyneille oppijoille. Omalla äidinkielellä näyttää olevan suuri vaikutus idiomien ymmärtämiseen, ja nimenomaan samankaltaisuudesta on hyötyä. Äidinkielen merkitykseen vieraiden kielten oppimisessa ja sanaston oppimisessa täytyisi kiinnittää enemmän huomiota, ja idiomeja sekä muuta kuvainnollista kieltä täytyisi opettaa myös edistyneemmille oppijoille.

Cholinergic as well as monoaminergic neurotransmission seems to be involved in the etiology of affective disorders. Chronic treatment with imipramine, a classical antidepressant drug, induces adaptive changes in monoaminergic neurotransmission. In order to identify possible changes in cholinergic neurotransmission we measured total, membrane-bound and soluble acetylcholinesterase (Achase) activity in several rat brain regions after chronic imipramine treatment. Changes in Achase activity would indicate alterations in acetylcholine (Ach) availability to bind to its receptors in the synaptic cleft. Male rats were treated with imipramine (20 mg/kg, ip) for 21 days, once a day. Twenty-four hours after the last dose the rats were sacrificed and homogenates from several brain regions were prepared. Membrane-bound Achase activity (nmol thiocholine formed min-1 mg protein-1) after chronic imipramine treatment was significantly decreased in the hippocampus (control = 188.8 ± 19.4, imipramine = 154.4 ± 7.5, P<0.005) and striatum (control = 850.9 ± 59.6, imipramine = 742.5 ± 34.7, P<0.005). A small increase in total Achase activity was observed in the medulla oblongata and pons. No changes in enzyme activity were detected in the thalamus or total cerebral cortex. Since the levels of Achase seem to be enhanced through the interaction between Ach and its receptors, a decrease in Achase activity may indicate decreased Ach release by the nerve endings. Therefore, our data indicate that cholinergic neurotransmission is decreased after chronic imipramine treatment which is consistent with the idea of an interaction between monoaminergic and cholinergic neurotransmission in the antidepressant effect of imipramine

Some upper brainstem cholinergic neurons (pedunculopontine and laterodorsal tegmental nuclei) are involved in the generation of rapid eye movement (REM) sleep and project rostrally to the thalamus and caudally to the medulla oblongata. A previous report showed that 96 h of REM sleep deprivation in rats induced an increase in the activity of brainstem acetylcholinesterase (Achase), the enzyme which inactivates acetylcholine (Ach) in the synaptic cleft. There was no change in the enzyme's activity in the whole brain and cerebrum. The components of the cholinergic synaptic endings (for example, Achase) are not uniformly distributed throughout the discrete regions of the brain. In order to detect possible regional changes we measured Achase activity in several discrete rat brain regions (medulla oblongata, pons, thalamus, striatum, hippocampus and cerebral cortex) after 96 h of REM sleep deprivation. Naive adult male Wistar rats were deprived of REM sleep using the flower-pot technique, while control rats were left in their home cages. Total, membrane-bound and soluble Achase activities (nmol of thiocholine formed min-1 mg protein-1) were assayed photometrically. The results (mean ± SD) obtained showed a statistically significant (Student t-test) increase in total Achase activity in the pons (control: 147.8 ± 12.8, REM sleep-deprived: 169.3 ± 17.4, N = 6 for both groups, P<0.025) and thalamus (control: 167.4 ± 29.0, REM sleep-deprived: 191.9 ± 15.4, N = 6 for both groups, P<0.05). Increases in membrane-bound Achase activity in the pons (control: 171.0 ± 14.7, REM sleep-deprived: 189.5 ± 19.5, N = 6 for both groups, P<0.05) and soluble enzyme activity in the medulla oblongata (control: 147.6 ± 16.3, REM sleep-deprived: 163.8 ± 8.3, N = 6 for both groups, P<0.05) were also observed. There were no statistically significant differences in the enzyme's activity in the other brain regions assayed. The present findings show that the increase in Achase activity induced by REM sleep deprivation was specific to the pons, a brain region where cholinergic neurons involved in REM generation are located, and also to brain regions which receive cholinergic input from the pons (the thalamus and medulla oblongata). During REM sleep extracellular levels of Ach are higher in the pons, medulla oblongata and thalamus. The increase in Achase activity in these brain areas after REM sleep deprivation suggests a higher rate of Ach turnover.

Differences in age and sex distribution as well as FAB (French-American-British classification) types have been reported for acute leukemias in several countries. We studied the demographics and response to treatment of patients with acute myeloid leukemia (AML) and acute lymphoblastic leukemia (ALL) between 1989 and 2000 in Teresina, Piauí, and compared these results with reports from Brazil and other countries. Complete data concerning 345 patients (230 ALL, 115 AML) were reviewed. AML occurred predominantly in adults (77%), with a median age of 34 years, similar to that found in the southeast of Brazil but lower than the median age in the United States and Europe (52 years). FAB distribution was similar in children and adults and FAB-M2 was the most common type, as also found in Japan. The high frequency of FAB-M3 described in most Brazilian studies and for Hispanics in the United States was not observed. Overall survival for adults was 40%, similar to other studies in Brazil. A high mortality rate was observed during induction. No clinical or hematological parameter influenced survival in the Cox model. ALL presented the characteristic peak of incidence between 2-8 years. Most of the cases were CD10+ pre-B ALL. In 25%, abnormal expression of myeloid antigens was observed. Only 10% of the patients were older than 30 years. Overall survival was better for children. Age and leukocyte count were independent prognostic factors. These data demonstrate that, although there are regional peculiarities, the application of standardized treatments and good supportive care make it possible to achieve results observed in other countries for the same chemotherapy protocols.

Tutkielmassa tarkastellaan Britannian parlamentissa käytyä keskustelua Kirkkovaltiosta ja paavin maallisesta vallasta vuosina 1858–1861. Aihetta tarkastellaan kolmen teeman kautta. Nämä teemat ovat Kirkkovaltion ajassa ja paikassa tapahtunut kontekstualisointi, paavin ja katolilaisten Britannialle aiheuttamasta sisäisestä ja ulkoisesta uhasta käyty keskustelu, sekä Kirkkovaltion liittäminen kansainvälisiin suhteisiin. Britannian ja Kirkkovaltion suhdetta 1800-luvun puolivälissä on käsitelty aikaisemmassa tutkimuksessa vain vähän. Suhtautumisen perusasenteena sekä konservatiiveilla että liberaaleilla on pidetty katolilaisvastaisuutta ja Kirkkovaltion lakkauttamisen ajamista. Tutkielmassa pyritään osoittamaan, että Britannian parlamentin jäsenten suhtautuminen oli kuitenkin moniulotteisempaa ja moniäänisempää, kuin pelkkä tiukka katolilaisvastaisuus. Parlamentin jäsenet pyrkivät kontekstualisoimaan Kirkkovaltiota käyttämällä vertauksia sekä Britanniaan ja Sardinian kuningaskuntaan, että erilaisiin historiallisiin tilanteisiin. Keskusteluun osallistuneilla parlamentin jäsenillä oli myös hyvin laaja skaala erilaisia kontakteja Italiaan ja Roomaan, ja he olivat hyvin perillä paavin maallisesta vallasta käydystä yleiseurooppalaisesta kirjallisesta debatista. Osa parlamentin jäsenistä näki paavin ja katolilaiset sekä sisäisenä että ulkoisena uhkana Britannialle, mikä liittyy vahvasti 1800-luvun puolivälin uhkakuvia täynnä olleeseen näkemykseen. Näkemys uhasta tiivistyi keskusteluun uskollisuudenvalan uudistamisesta vuonna 1858. Tässä keskustelussa esiin nousivat erityisesti ääriprotestanttiset, katolilaisvastaiset parlamentin jäsenet. Osa parlamentin jäsenistä näki paavin itsenäisyyden toisaalta myös hyvänä asiana, ja paavin maallisen vallan lakkauttamista uhkana Britannialle. Viimeisessä käsittelyluvussa tutkitaan suhtautumista Kirkkovaltioon kansainvälisten suhteiden tasolla. Britannialla ei ollut virallisia diplomaattisuhteita Kirkkovaltioon, mutta maan epävirallisista suhteista ja niiden kehittämisestä käytiin parlamentissa keskustelua. Parlamentissa keskusteltiin myös Ranskan ja Itävallan merkityksestä Kirkkovaltiolle, sekä Kirkkovaltion mahdollisista aluemenetyksistä tai jopa valtion lakkauttamisesta. Keskustelua käytiin myös brittien värväämisestä paavin armeijaan ja paavia vastustaneen Garibaldin joukkoihin.

The objective of this multicenter prospective study was to determine the clinical efficacy and toxicity of a polychemotherapeutic third generation regimen, VACOP-B, with or without radiotherapy as front-line therapy in aggressive localized non-Hodgkin's lymphoma. Ninety-three adult patients (47 males and 46 females, median age 45 years) with aggressive localized non-Hodgkin's lymphoma, 43 in stage I and 50 in stage II (non-bulky), were included in the study. Stage I patients received VACOP-B for 6 weeks plus involved field radiotherapy and stage II patients received 12 weeks VACOP-B plus involved field radiotherapy on residual masses. Eighty-six (92.5%) achieved complete remission and 4 (4.3%) partial remission. Three patients (3.2%) were primarily resistant. Ten-year probability of survival, progression-free survival and disease-free survival were 87.3, 79.9 and 83.9%, respectively. Eighty-four patients are surviving at a median observation time of 57 months (range: 6-126). Statistical analysis showed no difference between stages I and II in terms of response, ten-year probability of survival, progression-free survival or disease-free survival. Side effects and toxicity were negligible and were similar in the two patient groups. The results of this prospective study suggest that 6 weeks of VACOP-B treatment plus radiotherapy may be the therapy of choice in stage I aggressive non-Hodgkin's lymphoma. Twelve weeks of VACOP-B treatment with or without radiotherapy was shown to be effective and feasible for stage II. These observations need to be confirmed by a phase III study comparing first and third generation protocols in stage I-II aggressive non-Hodgkin's lymphoma.

The striatum, the largest component of the basal ganglia, is usually subdivided into associative, motor and limbic components. However, the electrophysiological interactions between these three subsystems during behavior remain largely unknown. We hypothesized that the striatum might be particularly active during exploratory behavior, which is presumably associated with increased attention. We investigated the modulation of local field potentials (LFPs) in the striatum during attentive wakefulness in freely moving rats. To this end, we implanted microelectrodes into different parts of the striatum of Wistar rats, as well as into the motor, associative and limbic cortices. We then used electromyograms to identify motor activity and analyzed the instantaneous frequency, power spectra and partial directed coherence during exploratory behavior. We observed fine modulation in the theta frequency range of striatal LFPs in 92.5 ± 2.5% of all epochs of exploratory behavior. Concomitantly, the theta power spectrum increased in all striatal channels (P < 0.001), and coherence analysis revealed strong connectivity (coefficients >0.7) between the primary motor cortex and the rostral part of the caudatoputamen nucleus, as well as among all striatal channels (P < 0.001). Conclusively, we observed a pattern of strong theta band activation in the entire striatum during attentive wakefulness, as well as a strong coherence between the motor cortex and the entire striatum. We suggest that this activation reflects the integration of motor, cognitive and limbic systems during attentive wakefulness.

Recent advances in Information and Communication Technology (ICT), especially those related to the Internet of Things (IoT), are facilitating smart regions. Among many services that a smart region can offer, remote health monitoring is a typical application of IoT paradigm. It offers the ability to continuously monitor and collect health-related data from a person, and transmit the data to a remote entity (for example, a healthcare service provider) for further processing and knowledge extraction. An IoT-based remote health monitoring system can be beneficial in rural areas belonging to the smart region where people have limited access to regular healthcare services. The same system can be beneficial in urban areas where hospitals can be overcrowded and where it may take substantial time to avail healthcare. However, this system may generate a large amount of data. In order to realize an efficient IoT-based remote health monitoring system, it is imperative to study the network communication needs of such a system; in particular the bandwidth requirements and the volume of generated data. The thesis studies a commercial product for remote health monitoring in Skellefteå, Sweden. Based on the results obtained via the commercial product, the thesis identified the key network-related requirements of a typical remote health monitoring system in terms of real-time event update, bandwidth requirements and data generation. Furthermore, the thesis has proposed an architecture called IReHMo - an IoT-based remote health monitoring architecture. This architecture allows users to incorporate several types of IoT devices to extend the sensing capabilities of the system. Using IReHMo, several IoT communication protocols such as HTTP, MQTT and CoAP has been evaluated and compared against each other. Results showed that CoAP is the most efficient protocol to transmit small size healthcare data to the remote servers. The combination of IReHMo and CoAP significantly reduced the required bandwidth as well as the volume of generated data (up to 56 percent) compared to the commercial product. Finally, the thesis conducted a scalability analysis, to determine the feasibility of deploying the combination of IReHMo and CoAP in large numbers in regions in north Sweden.

The emulsion stability, composition, structure and rheology of four different commercial italian salad dressings manufactured with traditional and light formulations were evaluated. According to the results, the fat content ranged from 8% (w/w) (light) to 34% (w/w) (traditional), the carbohydrate concentration varied between 3.8% (w/w) (traditional) and 14.4% (w/w) (light) and the pH was between 3.6-3.9 for all samples. The microscopic and stability analyses showed that the only stable salad dressing was a light sample, which had the smallest droplet size when compared with the other samples. With respect to the rheological behaviour, all the salad dressings were characterized as thixotropic and shear thinning fluids. However, the stable dressing showed an overshoot at relatively low shear rates. This distinct rheological behavior being explained by the differences in its composition, particularly the presence of a maltodextrin network.

The descriptive terminology and sensory prolife of four samples of Italian salami were determined using a methodology based on the Quantitative Descriptive Analysis (QDA). A sensory panel consensually defined sensory descriptors, their respective reference materials, and the descriptive evaluation ballot. Twelve individuals were selected as judges and properly trained. They used the following criteria: discriminating power, reproducibility, and individual consensus. Twelve descriptors were determined showing similarities and differences among the Italian salami samples. Each descriptor was evaluated using a 10 cm non-structured scale. The data were analyzed by ANOVA, Tukey test, and the Principal Component Analysis (PCA). The salami with coriander essential oil (T3) had lower rancid taste and rancid odor, whereas the control (T1) showed high values of these sensory attributes. Regarding brightness, T4 showed the best result. For the other attributes, T1, T2, T3, and T4 were similar.

Four formulations of Italian salami type were produced: without antioxidants; with essential oil of coriander essential oil (0.01%); with BHT (0.01%); and with Coriander essential oil and BHT (0.005 and 0.005%). The antioxidant activity of salamis was evaluated by the lipid oxidation, through the techniques of peroxide number and TBARS. The salami with the coriander essential oil exhibited reduction in lipid oxidation by increasing the shelf life of the product. The salami with the coriander essential oil and BHT showed no synergism between the antioxidants. The salami using BHT presented less antioxidant activity than that of the salami using coriander essential oil.
