Structure dependent antioxidant capacity of phlorotannins from Icelandic Fucus vesiculosus by UHPLC-DAD-ECD-QTOFMS

Brown algae are rich in polyphenolic compounds, phlorotannins, which have been found to possess high in vitro antioxidant capacity, especially DPPH radical scavenging activity, due to the high number of hydroxyl groups. Whereas, the overall antioxidant capacity of brown algae extracts has been widely studied, the antioxidant capacity of individual phlorotannins has been rarely explored. The aim of

Background: The effects of "maternal environment" on fetal development have been studied since the eighties, but the results regarding the features which influence mother-fetus relationship are inconsistent. Aim: To develop a mother-fetus relationship assessment scale on a Hungarian sample, and to reveal the factors that determine mother-fetus bonding. Method: 114 pregnant women, between 15 and 38

Ultrasonically-enhanced preparation, characterization of CaFe-layered double hydroxides with various interlayer halide, azide and oxo anions (CO3 2−, NO3 , ClO4 )

An ultrasonically-enhanced mechanochemical method was developed to synthesize CaFe-layered double hydroxides (LDHs) with various interlayer anions (CO3 2−, NO3 −, ClO4 −, N3 −, F−, Cl−, Br− and I−). The duration of pre-milling and ultrasonic irradiation and the variation of synthesis temperature in the wet chemical step were investigated to obtain the optimal parameters of preparation. The main me

Patients' views on early sensory relearning following nerve repair-a Q-methodology study

Study Design: Descriptive study. Introduction: Early sensory relearning where the dynamic capacity of the brain is used has been shown to improve sensory outcome after nerve repair. However, no previous studies have examined how patients experience early sensory relearning. Purpose of the Study: To describe patient's views on early sensory relearning. Methods: Statements' scores were analyzed by f

Antioxidant capacity and major phenol compounds of horticultural plant materials not usually used

Horticultural plant materials not usually used from onion, carrot, beetroot, sea buckthorn, black and red currants as well as a wastewater powder from olive oil production were analyzed for total phenols content (FC), ferric reducing ability of plasma (FRAP), radical scavenging capacity (ABTS), and for major phenolic compounds by HPLC-MS. Antioxidant capacity and phenol content varied significantl

Prematurity and neonatal outcome including congenital malformations after maternal malignancy within six months prior to or during pregnancy

Introduction: The proportion of women who postpone childbearing is increasing. As malignancy risk increases with age, pregnancy in connection with malignancy will become more common. Material and methods: We compared infants born 1994-2011 to women with a malignancy within six months prior to the last menstrual period or during pregnancy with offspring of women without a previous malignancy. Five

Climbing the cosmic ladder with stellar twins in RAVE with Gaia

We apply the twin method to determine parallaxes to 232 545 stars of the RAVE survey using the parallaxes of Gaia DR1 as a reference. To search for twins in this large data set, we apply the t-student stochastic neighbour embedding projection that distributes the data according to their spectral morphology on a two-dimensional map. From this map, we choose the twin candidates for which we calculat

Networking our science to characterize the state, vulnerabilities, and management opportunities of soil organic matter

Soil organic matter (SOM) supports the Earth's ability to sustain terrestrial ecosystems, provide food and fiber, and retains the largest pool of actively cycling carbon. Over 75% of the soil organic carbon (SOC) in the top meter of soil is directly affected by human land use. Large land areas have lost SOC as a result of land use practices, yet there are compensatory opportunities to enhance prod

Man, en och du : Generiska pronomen i svenskans historia

This thesis examines the development of three generic pronouns in the history of the Swedish language, from the year of ca. 1225 until today. The analysis focuses on how the former noun man (‘man’), numeral en (‘one’) and personal pronoun du (‘you’) have turned into generic pronouns, thereby referring to one or a number of arbitrarily chosen human individuals. Furthermore, the study maps how the g

Method for evaluation of renovation measures with regards to moisture and emission loads : Based on risk assessments

Renovating the European building stock has for almost two decades been a matter of importance. For Sweden, it is important to renovate its multifamily buildings in order to achieve a reduced energy use, but also because renovation is needed due to building materials and services reaching (or having passed) the end of their life span. In order to renovate properly, renovation measures must be imple

Random telegraph signal noise in tunneling field-effect transistors with S below 60 mV/decade

Single gate oxide defects in strongly scaled Tunneling Field-Effect Transistors with an inverse subthreshold slope well below 60 mV/decade are investigated by Random Telegraph Signal (RTS) noise measurements. The cause for RTS noise are electrons being captured in and released from individual defects in the gate oxide. Under the assumption that elastic tunneling is the underlying capture and emiss

En skolbyggnads statusbedömning och renoveringsmöjligheter

Med utgångspunkt i Miljöbyggnad, det svenska miljöcertifieringssystemet, har en skolbyggnads status utvärderats. De bedömda indikatorerna inom energi, inomhusmiljö och material gav en bred och övergriplig bild av byggnadens skick och utvärderingen ger en bra grund för det fortsatta arbetet. Skolbyggnaden Kullagymnasiet i Höganäs, Skåne, bedöms nå certifieringsnivån brons, vilket minst motsvarar sa

Erfarenhetsåterföring vid renovering

Nationellt Renoveringscentrum (NRC) bildades 2013 för att arbeta med kunskapshöjning och informationsspridning om en effektiv renoveringsprocess. Centret siktar på att samla och föra vidare kunskap om hur renovering av befintlig bebyggelse kan genomföras både effektivt för involverade aktörer såväl som socialt, ekonomiskt och miljömässigt hållbart för samhället. Kunskap från både akademi och närin

MicroRNAs in Retinal Pathophysiology and Therapeutics

Following identification of tRNA and rRNA, the non-protein coding RNAs (ncRNAs) have been demonstrated to possess catalytic ribozyme functions (Cech et al., 1981; Guerrier-Takada et al., 1983). In recognition of the latter work, T.R. Cech and S. Altman were awarded the 1989 Noble Prize in Chemistry. Fire, et al. (1998) discovered that small double stranded RNA (ds RNA) silences the gene expression

Pioneers for the Basic Understanding of Usher syndrome

After the first description of the inherited nature of bimodal deaf-blindness disease in mid nineteenth century by pioneering ophthalmologists Albrecht von Graefe (May 22, 1828 ± July 20, 1870) and Richard Liebreich (June 30, 1830 - January 19, 1917) followed by its confirmation in early twentieth century from a larger number of patients by another pioneer ophthalmologist Charles Howard Usher (Mar
