Suomalaisten marjojen fenoliyhdisteet ja niiden stabiilisuus prosessoinnin ja säilytyksen aikana

Suomalaiset marjat sisältävät huomattavia määriä erilaisia fenoliyhdisteitä ja ne ovat siksi erinomaisia fenoliyhdisteiden lähteitä moniin muihin elintarvikkeisiin verrattuna. Fenoliyhdisteet ovat kasveissa syntyviä aineenvaihduntatuotteita, joilla on todettu olevan terveyden kannalta positiivia vaikutuksia. Ne antavat kasvikunnan tuotteille niiden tunnusomaisen värin sekä toimivat suoja-aineina taudinaiheuttajia vastaan. Erityisesti elintarvike-, lääke- ja kosmetiikkateollisuus jalostavat marjoja erilaisiksi lopputuotteiksi. Fenoliyhdisteet tuovat näihin tuotteisiin hyödyllisiä terveysvaikutuksia ja ne voivat toimia niissä myös väripigmentteinä. Fenoliyhdisteet ovat kuitenkin suhteellisen epästabiileja yhdisteitä. On havaittu, että prosessointi- ja säilytystavat vaikuttavat huomattavasti niiden stabiilisuuteen ja hajoamiseen. Tämän kandidaatintyön tavoitteena oli selvittää fenoliyhdisteiden stabiilisuuteen vaikuttavia tekijöitä prosessoinnin ja säilytyksen aikana kirjallisuuden pohjalta. Tämän työn tulosten perusteella marjojen prosessointi kannattaa suorittaa mahdollisimman lyhyessä ajassa matalissa lämpötiloissa, sillä monet fenoliyhdisteistä eivät ole pitkään lämpöstabiileja. Säilytys kannattaa tehdä myös matalissa lämpötiloissa; pitkänä säilytysaikana pakastettuna. Korkea pH vaikuttaa usean fenoliyhdisteen hajoamiseen ja se saattaa aiheuttaa tuotteissa värinmuutoksia. Valo, hapen läsnäolo sekä erilaiset muut yhdisteet voivat vaikuttaa heikentävästi fenoliyhdisteiden stabiilisuuteen sekä prosessoinnin että säilytyksen aikana. Fenoliyhdisteiden stabiilisuus on hyvin rakennekohtaista ja siksi prosessoinnin ja säilytyksen tarkkojen vaikutusten yleistäminen kaikkiin fenoliyhdisteisiin on vaikeaa.

A Survey of the 2010 Quartz Crystal Microbalance Literature

In 2010 there has again been an increase in the number of papers published involving piezoelectric acoustic sensors, or quartz crystal microbalances (QCM), when compared to the last period reviewed 2006-2009. The average number of QCM publications per annum was 124 in the period 2001-2005, 223 in the period 2006-9, and 273 in 2010. There are trends towards increasing use of QCM in the study of protein adsorption to surfaces (93% increase), homeostasis (67% increase), protein-protein interactions (40% increase), and carbohydrates (43% increase). New commercial systems have been released that are driving the uptake of the technology for characterisation of binding specificities, affinities, kinetics and conformational changes associated with a molecular recognition event. This article highlights theoretical and practical aspects of the principals that underpin acoustic analysis, then reviews exemplary papers in key application areas involving small molecular weight ligands, carbohydrates, proteins, nucleic acids, viruses, bacteria, cells, and membrane interfaces.

More than thirty years of ultimatum bargaining experiments: Motives, variations, and a survey of the recent literature

Take-it or leave-it offers are probably as old as mankind. Our objective here is, first, to provide a, probably subjectively colored, recollection of the initial ultimatum game experiment, its motivation and the immediate responses. Second, we discuss extensions of the standard ultimatum bargaining game in a unified framework, and, third, we offer a survey of the experimental ultimatum bargaining literature containing papers published since the turn of the century. The paper argues that the ultimatum game is a versatile tool for research in bargaining and on social preferences. Finally, we provide examples for open research questions and directions for future studies.

A methodological survey of future mobility literature: Opportunities for design research

This research establishes that the study of mobility and transportation is multi-disciplinary and highly complex, involving the diverse interplay between infrastructural and psychological factors. Coincidently, a new paradigm in personal mobility is developing. A new generation of mobility solutions is becoming widely available in the form of car and ride sharing services. These services build on the assumption that customers no longer need ownership of a product in order to benefit from it. With the emergence of this new paradigm, this paper presents a methodological review of current practises used by the wider research community. Therefore, this research piece aims to explore methodological approaches involved in the study the effect of community on an individual’s attitudes, perceptions and behaviours of future mobility solutions. The results of this review indicate that the majority of published literature uses quantitative methods as opposed to qualitative and even fewer studies have sought to understand the human factors in these new mobility solutions. This gap in knowledge is a valuable opportunity for design. Inherently qualitative and human focused, design research can fill this gap in knowledge by applying distinctly user-centred methods such as persona design, narrative storytelling, and in-depth observations to discover deeper human insights.

Mersey Estuary baseline survey. Analysis of macroinfaunal samples, literature review and database production

This is the Mersey Estuary baseline survey: Analysis of macroinfaunal samples, literature review and database production report produced by the Environment Agency North West in 2002. This report presents an ecological review of the Mersey estuary along with an extensive bibliography of the available environmental literature for this system. The central objective of this programme has been to provide the information necessary to support the Environment Agency's review of existing and future consents (for discharges, abstractions etc) in the Mersey estuary. This review of consents was required because the Mersey had been designated as a Special Protection Area (SPA) under the EC Birds Directive. Therefore under Regulation 50 of the Conservation, the Environment Agency was responsible for reviewing any extant consent, or future applications, which may directly or indirectly, affected this SPA.

Retinal vascular occlusion after vitrectomy with retrobulbar anesthesia-observational case series and survey of literature

BACKGROUND: Severe postoperative loss of vision has been occasionally reported as a rare complication of retrobulbar anesthesia, and several possible causes have been proposed in the literature. In this work, our own and other investigators' experiences with these complications are surveyed with a view to identifying its pathophysiology. PATIENTS: This observational case series refers to six patients who presented during a 3-month period with occlusion of either the central artery itself (n = 3) or a branch thereof (n = 3) 2-14 days after uneventful vitreoretinal surgery following retrobulbar anesthesia with a commercial preparation of mepivacaine (1% Scandicain®, Astra Chemicals, Sweden) containing methyl- and propyl parahydroxybenzoate as preservatives. RESULTS: Three of the patients carried risk factors, which were medically controlled. In three individuals, vasoocclusion was observed after a second vitreoretinal intervention, which was performed 3-12 months after uneventful primary surgery. Good visual recovery was observed in only one instance. CONCLUSIONS: In patients who were anesthetized with preservative-free mepivacaine, no vasoocclusion occurred. In individuals who were anesthetized with mepivacaine containing the preservatives methyl- and propyl parahydroxybenzoate, a tenfold increase in the incidence of eyes requiring re-operation was documented, with a 2- to 14-day lapse in the onset of vasoocclusion. These findings reveal a possible implication of preservatives contained in the local anesthetic solution for the vasoocclusive events. Due to this potential hazard, the use of preservative-free preparations of local anesthesia in ocular surgery is emphasized in order to prevent this sight-threatening complication.

Literature review of estimation of prevalence rate of HIV/AIDS in India using population survey and sentinel surveillance based data

HIV/AIDS is a treatable although incurable disease that presents immense challenges to those infected including physical, social and psychological effects. As of 2009, an estimated 2.4 million people were living with HIV or AIDS in India, 0.3% of the country's population. In India, it is difficult to not only treat but also to track because it is associated with socio-economic factors such as illiteracy, social biases, poor sanitation, malnutrition and social class. Nevertheless, it is important to know the prevalence of HIV/AIDS for several reasons. At the individual level, the quality of life of people living with HIV/AIDS is markedly lower than their counterparts without the disease and is associated with challenges. At the community level, it is important to identify high risk groups, monitor prevention efforts, and allocate appropriate resources to target programs for the reduction of transmission of HIV. ^
