The exponential growth of studies on the biological response to ocean acidification over the last few decades has generated a large amount of data. To facilitate data comparison, a data compilation hosted at the data publisher PANGAEA was initiated in 2008 and is updated on a regular basis (doi:10.1594/PANGAEA.149999). By January 2015, a total of 581 data sets (over 4 000 000 data points) from 539 papers had been archived. Here we present the developments of this data compilation five years since its first description by Nisumaa et al. (2010). Most of study sites from which data archived are still in the Northern Hemisphere and the number of archived data from studies from the Southern Hemisphere and polar oceans are still relatively low. Data from 60 studies that investigated the response of a mix of organisms or natural communities were all added after 2010, indicating a welcomed shift from the study of individual organisms to communities and ecosystems. The initial imbalance of considerably more data archived on calcification and primary production than on other processes has improved. There is also a clear tendency towards more data archived from multifactorial studies after 2010. For easier and more effective access to ocean acidification data, the ocean acidification community is strongly encouraged to contribute to the data archiving effort, and help develop standard vocabularies describing the variables and define best practices for archiving ocean acidification data.

This thesis examines three key moments in the intersecting histories of Scotland, Ireland and England, and their impact on literature. Chapter one Robert Bruce and the Last King of Ireland: Writing the Irish Invasion, 1315- 1826‘, is split into two parts. Part one, Barbour‘s (other) Bruce‘ focuses on John Barbour‘s The Bruce (1375) and its depiction of the Bruce‘s Irish campaign (1315-1318). It first examines the invasion material from the perspective of the existing Irish and Scottish relationship and their opposition to English authority. It highlights possible political and ideological motivations behind Barbour‘s negative portrait of Edward Bruce - whom Barbour presents as the catalyst for the invasion and the source of its carnage and ultimate failure - and his partisan comparison between Edward and his brother Robert I. It also probes the socio-polticial and ideological background to the Bruce and its depiction of the Irish campaign, in addition to Edward and Robert. It peers behind some of the Bruce‘s most lauded themes such as chivalry, heroism, loyalty, and patriotism, and exposes its militaristic feudal ideology, its propaganda rich rhetoric, and its illusions of freedom‘. Part one concludes with an examination of two of the Irish section‘s most marginalised figures, the Irish and a laundry woman. Part two, Cultural Memories of the Bruce Invasion of Ireland, 1375-1826‘, examines the cultural memory of the Bruce invasion in three literary works from the Medieval, Early Modern and Romantic periods. The first, and by far the most significant memorialisation of the invasion is Barbour‘s Bruce, which is positioned for the first time within the tradition of ars memoriae (art of memory) and present-day cultural memory theories. The Bruce is evaluated as a site of memory and Barbour‘s methods are compared with Icelandic literature of the same period. The recall of the invasion in late sixteenth century Anglo-Irish literature is then considered, specifically Edmund Spenser‘s A View of the State of Ireland, which is viewed in the context of contemporary Ulster politics. The final text to be considered is William Hamilton Drummond‘s Bruce’s Invasion of Ireland (1826). It is argued that Drummond‘s poem offers an alternative Irish version of the invasion; a counter-memory that responds to nineteenth-century British politics, in addition to the controversy surrounding the publication of the Ossian fragments. Chapter two, The Scots in Ulster: Policies, Proposals and Projects, 1551-1575‘, examines the struggle between Irish and Scottish Gaels and the English for dominance in north Ulster, and its impact on England‘s wider colonial ideology, strategy, literature and life writing. Part one entitled Noisy neighbours, 1551-1567‘ covers the deputyships of Sir James Croft, Sir Thomas Radcliffe, and Sir Henry Sidney, and examines English colonial writing during a crucial period when the Scots provoked an increase in militarisation in the region. Part two Devices, Advices, and Descriptions, 1567-1575‘, deals with the relationship between the Scots and Turlough O‘Neill, the influence of the 5th Earl of Argyll, and the rise of Sorley Boy MacDonnell. It proposes that a renewed Gaelic alliance hindered England‘s conquest of Ireland and generated numerous plantation proposals and projects for Ulster. Many of which exhibit a blurring‘ between the documentary and the literary; while all attest to the considerable impact of the Gaelic Scots in both motivating and frustrating various projects for that province, the most prominent of which were undertaken by Sir Thomas Smith in 1571 and Walter Devereux, 1st Earl of Essex in 1573.

A novel protocol for rapid and efficient purification of antimicrobial peptides from plant seedlings has been developed. Two peptides with antimicrobial activity, designated p1 and p2, were purified nearly to homogeneity from Scots pine seedlings by a combination of sulfuric acid extraction, ammonium sulfate precipitation, heat-inactivation and ion-exchange chromatography on phosphocellulose. Purified proteins had molecular masses of 11 kDa (p1) and 5.8 kDa (p2) and were identified by mass spectrometry as defensin and lipid-transfer protein, respectively. We demonstrated their growth inhibitory effects against a group of phytopathogenic fungi. Furthermore, we report for the first time molecular cloning and characterization of defensin I cDNA from Scots pine. A cDNA expression library from 7 days Scots pine seedlings was generated and used to isolate a cDNA clone corresponding to Scots pine defensin, termed PsDef1. The full-length coding sequence of PsDef1 is 252 bp in length and has an open reading frame capable to encode a protein of 83 amino residues. The deduced sequence has the typical features of plant defensins, including an endoplasmic reticulum signal sequence of 33 aa, followed by a characteristic defensin domain of 50 amino acids representing its active form. The calculated molecular weight of the mature form of PsDef1 is 5601.6 Da, which correlates well with the results of SDS-PAGE analysis. Finally, the antimicrobial properties of PsDef1 against a panel of fungi and bacteria define it as a member of the morphogenic group of plant defensins. (C) 2009 Elsevier Inc. All rights reserved.

Protein tyrosine phosphorylation in angiosperms has been implicated in various physiological processes, including seed development and germination. In conifers, the role of tyrosine phosphorylation and the mechanisms of its regulation are yet to be investigated. In this study, we examined the profile of protein tyrosine phosphorylation in Scots pine seeds at different stages of germination. We detected extensive protein tyrosine phosphorylation in extracts from Scots pine (Pinus sylvestris L.) dormant seeds. In addition, the pattern of tyrosine phosphorylation was found to change significantly during seed germination, especially at earlier stages of post-imbibition which coincides with the initiation of cell division, and during the period of intensive elongation of hypocotyls. To better understand the molecular mechanisms of phosphotyrosine signaling, we employed affinity purification and mass spectrometry for the identification of pTyr-binding proteins from the extracts of Scots pine seedlings. Using this approach, we purified two proteins of 10 and 43 kDa, which interacted specifically with pTyr-Sepharose and were identified by mass spectrometry as P. sylvestris defensin 1 (PsDef1) and aldose 1-epimerase (EC:5.1.3.3), respectively. Additionally, we demonstrated that both endogenous and recombinant PsDef1 specifically interact with pTyr-Sepharose, but not Tyr-beads. As the affinity purification approach did not reveal the presence of proteins with known pTyr binding domains (SH2, PTB and C2), we suggest that plants may have evolved a different mode of pTyr recognition, which yet remains to be uncovered.

BACKGROUND: Several clinical studies on chronic stroke conducted with end-effector-based robots showed improvement of the motor function in the affected arm. Compared to end-effector-based robots, exoskeleton robots provide improved guidance of the human limb and are better suited to train task-oriented movements with a large range of motions. OBJECTIVE: To test whether intensive arm training with the arm exoskeleton ARMin I is feasible with chronic-stroke patients and whether it improves motor function in the paretic arm. METHODS: Three single cases with chronic hemiparesis resulting from unilateral stroke (at least 14 months after stroke). A-B design with 2 weeks of multiple baseline measurements (A), 8 weeks of training (B) with repetitive measurements and a follow-up measurement 8 weeks after training. The training included shoulder and elbow movements with the robotic rehabilitation device ARMin I. Two subjects had three 1-hour sessions per week and 1 subject received five 1-hour sessions per week. The main outcome measurement was the upper-limb part of the Fugl-Meyer Assessment (FMA). RESULTS: The ARMin training was well tolerated by the patients, and the FMA showed moderate, but significant improvements for all 3 subjects (p < 0.05). Most improvements were maintained 8 weeks after discharge. CONCLUSIONS: This study indicates that intensive training with an arm exoskeleton is feasible with chronic-stroke patients. Moderate improvements were found in all 3 subjects, thus further clinical investigations are justified.

The purpose of this thesis will be to examine how two acts of rebellion against Queen Elizabeth I influenced Shakespeare's writing of Richard II and Henry V, as well as the performance and publication of these plays. The treasonous plots and execution of Mary, Queen of Scots in the 1580s, as well as the failed Essex Rebellion of 1601, resulted in a sensitivity towards any writings that seemed to support a coup d'état. Shakespeare, being a well-informed and fairly well-connected playwright, wrote passages in the afore mentioned plays that clearly reflect the political turmoil of the times. Thus, his plays were censored both on stage and in print until after the death of Elizabeth in 1603.

We have investigated the dynamic properties of the switch I region of the GTP-binding protein Ras by using mutants of Thr-35, an invariant residue necessary for the switch function. Here we show that these mutants, previously used as partial loss-of-function mutations in cell-based assays, have a reduced affinity to Ras effector proteins without Thr-35 being involved in any interaction. The structure of Ras(T35S)⋅GppNHp was determined by x-ray crystallography. Whereas the overall structure is very similar to wildtype, residues from switch I are completely invisible, indicating that the effector loop region is highly mobile. 31P-NMR data had indicated an equilibrium between two rapidly interconverting conformations, one of which (state 2) corresponds to the structure found in the complex with the effectors. 31P-NMR spectra of Ras mutants (T35S) and (T35A) in the GppNHp form show that the equilibrium is shifted such that they occur predominantly in the nonbinding conformation (state 1). On addition of Ras effectors, Ras(T35S) but not Ras(T35A) shift to positions corresponding to the binding conformation. The structural data were correlated with kinetic experiments that show two-step binding reaction of wild-type and (T35S)Ras with effectors requires the existence of a rate-limiting isomerization step, which is not observed with T35A. The results indicate that minor changes in the switch region, such as removing the side chain methyl group of Thr-35, drastically affect dynamic behavior and, in turn, interaction with effectors. The dynamics of the switch I region appear to be responsible for the conservation of this threonine residue in GTP-binding proteins.
