Stabilization of unusual structures in peptides using alpha,beta-dehydrophenylalanine: Crystal and solution structures of Boc-Pro-Delta Phe-Val-Delta Phe-Ala-OMe and Boc-Pro-Delta Phe-Gly-Delta Phe-Ala-OMe

The structures of two dehydropentapeptides, Boc-Pro-Delta Phe-Val-Delta Phe-Ala-OMe (I) and Boc-Pro-Delta Phe-Gly-Delta Phe-Ala-OMe (II) (Boc: t-butoxycarbonyl), have been determined by nuclear magnentic resonance (NMR), circular dichroism (CD), and X-ray, crystallographic studies. The peptide I assumes a S-shaped flat beta-bend structure, characterized by two partially overlapping type II beta-bends and absence of a second 1 <- 4 (N4-H center dot center dot center dot O1') intramolecular hydrogen bond. This is in contrast to the generally observed 3(10)-helical conformation in peptides with Delta Phe at alternate positions. This report describes the novel conformation assumed by peptide I and compares it with that of the conserved tip of the V3 loop of the HIV-1 envelope glycoprotein gp120 (sequence, G:P319 to F:P324, PDB code IACY). The tip of the V3 loop also assumes a S-shaped conformation with Arg:P322, making an intramolecular side-chain-backbone interaction with the carbonyl oxygen of Gly:P319. Interestingly, in peptide I, C(gamma)HVal(3) makes a similar side-chain-backbone C-H center dot center dot center dot O hydrogen bond with the carbonyl oxygen of the Boc group. The observed overall similarity indicates the possible use of the peptide as a viral antagonist or synthetic antigen. Peptide 11 adopts a unique turn followed by a 3(10)-helix. Both peptides I and II are classical examples of stabilization of unusual structures in oligopeptides.

Polypeptide models of collagen. II. Solution properties of (Pro-Gly-Phe)n

The conformation of (Pro-Gly-Phe)n in trifluoroethanol was investigated using CD, nmr and ir techniques. After making appropriate correction for the contribution of the phenylalanine chromophore to the observed CD spectra of the polytripeptide at several temperatures, it is found that (Pro-Gly-Phe)n can exist in a partially triple-helical conformation in this solvent a t low temperatures. The nmr and ir data support this conclusion. In conjunction with recent theoretical sutdies, our data offer an explanation for the preferential occurrence of the Phe residue in position 2 of the tripeptide sequence Gly-R2-R3, in collagen.

Aspergillus niger -proliiniendopeptidaasi prolamiinien eliminoinnissa

Tutkielman kirjallisuusosassa perehdyttiin vehnän, rukiin ja ohran, eli Triticeaeprolamiinien erityisasemaan keliakianäkökulmasta tarkasteltuna ja prolamiinien hydrolyysiin proliinispesifeillä entsyymeillä. Lisäksi tarkasteltiin prolamiinien immunologisia määritysmenetelmiä. Keliakiassa haitalliset gluteenipeptidit sisältävät runsaasti proliinia ja ovat hankalia pilkkoa muilla kuin proliinispesifeillä peptidaaseilla. Suurin osa immunologisen reaktion aiheuttavista gluteenilähtöisistä peptideistä voidaan pilkkoa idätetyn viljan endogeenisilla entsyymeillä happamissa olosuhteissa, mutta jäljellejäävä prolamiinipitoisuus ylittää edelleen gluteenittomille tuotteille sallitun rajan. Kokeellisen työn tavoitteena oli eliminoida happamalla mallasinkubaatiolla valmistettujen vehnä-, ohra- ja ruismallasautolysaattien sisältämä jäännösprolamiini Aspergillus niger -homeen tuottamalla proliinispesifillä endopeptidaasilla (AN-PEP) siten, että hydrolysaattia voitaisiin käyttää gluteenittomissa leivontasovelluksissa. Proteiinien hydrolyysiä tarkkailtiin kokoekskluusiokromatografialla (SEC), vapaan aminotypen (FAN) muodostumisena ja SDS-PAGE-elektroforeesilla. Jäännösprolamiinien pilkkoutumista seurattiin immunologisella R5-ELISA-menetelmällä. AN-PEP-inkubaatiolla saatiin aikaan voimakasta prolamiinien pilkkoutumista; mallasautolysaattien jäännösprolamiinista pilkkoutui yli 96 %. SEC- ja FAN-analyysien perusteella inkubaatioaikaa kannatti jatkaa yli 4 h, jolloin polypeptidit pilkkoutuivat edelleen pienemmiksi hydrolyysituotteiksi. Vehnä- ja ruismallashydrolysaattien prolamiinipitoisuuden todettiin laskevan 22 h inkubaation aikana alle tason 100 mg/kg R5-ELISA-menetelmällä määritettynä. Matalimmat prolamiinipitoisuudet saavutettiin AN-PEP-pitoisuudella 35 ?l / g mallasautolysaattia. Codex Alimentarius -komission säädöksen mukaan keliakiaruokavalioon soveltuvat ns. erittäin vähägluteeniset tuotteet saavat sisältää gluteenia enintään 100 mg/kg. Erityisesti AN-PEP-käsiteltyä ruismallasraaka-ainetta voitaisiin mahdollisesti käyttää tuomaan rukiista aromia gluteenittomiin leipiin. Ennen kuin mallashydrolysaatit ovat valmiita kaupallisiin sovelluksiin, on tarkasteltava niiden todellisia mahdollisuuksia parantaa elintarvikkeiden makua ja aromia sekä todettava uuden teknologian turvallisuus keliaakikoille.

Maskuliinisuuden rakentuminen alakoulussa

Objectives: Inspiration for this study came from the public discourse and concern for boys poor school achievement, as well as from the author s own perceptions. There was an interest to know if this concern is justified and what are its underlying causes. Previous studies have shown that masculinity is one of the key aspects of boys' poor school achievement. The objective of this research is to study the construction of masculinity in primary school and how this construct of masculinity is manifested by school achievement. Based on previous studies, the pursuit of hegemonic masculinity does not fit with good school grades. If a boy succeeds in school, this success must be compensated for by means of different factors demonstrating hegemonic masculinity. Methods: The research material was obtained by using the etnographic method. The research settled itself feministic school-etnographic research field. The research subjects comprised pupils and teachers of a 5th grade comprehensive school class (10-11-year-olds) in the Uusimaa county. There were twenty-nine (29) pupils (18 boys and 11 girls) in this class and five (5) different teachers who taught the class. The research material was composed of field notes and researcher's diary based on researcher's observations, short group discussions with pupils and interviews of five boys. The field notes consisted of twenty-six (26) lessons and also observations of breaks and eating periods. In short group discussions the researcher discussed with all the pupils that were given a permission for interview. The material was analysed with thematic and analytic reading that led to the writing of an analysis. Results and conclusions: The most salient result of this study was that different masculinities are constructed in primary school. The majority of boys aimed at hegemonic masculinity and the school community strongly supported this. This was shown in speech and in behaviour. School success and mainstream masculinity could be compatible, but success also required compensatory aspects. In addition to these observations, the researcher was able to identify a group of boys which truly wanted to achieve well in school and did not care to strive for hegemonic masculinity. Thus, there should be more room and opportunities for different kinds of masculinity in the school environment. Teachers and the overall school environment should support the different ways of being a boy, and it seems there is a need for gender sensitive pedagogy.

Levosimendaanin vaikutusmekanismi ja nykyinen merkitys sydämen vajaatoiminnan hoidossa

Sydämen vajaatoiminta on erilaisista sydän- ja verisuonisairauksista aiheutuva monimuotoinen oireyhtymä, johon sairastuneiden ja kuolleiden potilaiden määrä on yhä suuri. Sen patofysiologiaan voi kuulua muun muassa sympaattisen hermoston ja reniini-angiotensiini-aldosteroni–järjestelmän aktiivisuutta, huonosti supistuva vasen kammio, sydämen uudelleenmuokkautumista, muutoksia [Ca2+]i:n säätelyssä, kardiomyosyyttien apoptoosia sekä systeeminen tulehdustila. Johonkin osaan sairauden patofysiologiasta eivät nykyiset lääkehoidot riittävästi vaikuta. Klassiset inotroopit lisäävät sydämen supistusvireyttä kasvattamalla solunsisäistä Ca2+-pitoisuutta, mutta ne lisäävät rytmihäiriöriskiä, sydämen hapenkulutusta sekä heikentävät ennustetta. Levosimendaani, kalsiumherkistäjä, lisää sydämen supistusvoimaa [Ca2+]i:ta kohottamatta herkistämällä sydänlihaksen kalsiumin vaikutuksille. Lisäksi levosimendaani avaa sarkolemmaalisia ja mitokondriaalisia K+-kanavia, jotka välittävät vasodilataatiota ja kardioprotektiota. Suurilla annoksilla levosimendaani on selektiivinen PDE3-estäjä. Levosimendaania suositellaan äkillisesti pahentuneen sydämen vajaatoiminnan hoitoon, mutta muitakin lupaavia indikaatioita sille on keksitty. Esimerkiksi kroonisesti annosteltu oraalinen levosimendaani on suojannut kardiovaskulaarijärjestelmää ja parantanut selviytymistä in vivo. Erikoistyössä selvitettiin kroonisesti annostellun oraalisen levosimendaanin, valsartaanin ja näiden kombinaatioterapian vaikutuksia selviytymiseen, verenpaineeseen sekä sydämen hypertrofioitumiseen Dahlin suolaherkillä (Dahl/Rapp) rotilla. Levosimendaanin suojavaikutus ilmeni vähäisempänä kuolleisuutena, mutta ero ei ollut tilastollisesti merkitsevä kontrolliryhmään nähden. Kombinaatioterapia suojasi rottia kardiovaskulaarikuolleisuudelta ja vähensi todennäköisesti verenpaineesta riippuvaisesti sydämen hypertofioitumista niin sydän/kehonpaino–suhteen kuin ultraäänitutkimuksenkin perusteella arvioituna paremmin kuin kumpikaan lääke monoterapiana. Lääkekombinaatio alensi additiivisesti hypertensiota kaikissa mittauspisteissä. Sydämen systolista toimintaa levosimendaani kohensi vain vähäisesti. Dahl/Rapp-rotille kehittyikin pääosin hypertension indusoimaa diastolista sydämen vajaatoimintaa kohonneen IVRT-arvon perusteella. Levosimendaani sekä monoterapiana että kombinaatioterapiana valsartaanin kanssa vähensi sydämen diastolista vajaatoimintaa.

Singing from the same hymn sheet? A closer look at the framing of human trafficing by counter-trafficing actors in Lao PDR

As disparities in wealth levels between and within countries become greater many poor people migrate in search of better earning opportunities. Some of this migration is legal but, in many cases, the difficulties involved in securing the necessary documentation mean that would-be migrants resort to illegal methods. This, in turn, makes them vulnerable to human trafficking, a phenomenon that has received growing attention from NGOs, governments and the media in recent years. Despite the attention being given to human trafficking, however, there remains a certain amount of confusion over what exactly it entails though it is generally understood to refer to the transportation and subsequent exploitation of vulnerable people through means of force or deception. The increased attention that has been given to the issue of human trafficking over the last decade has resulted in new discourses emerging which attempt to explain what human trafficking entails, what the root causes of the phenomenon are and how best to tackle the problem. While a certain degree of conceptual clarity has been attained since human trafficking rose to prominence in the 1990s, it could be argued that human trafficking remains a poorly defined concept and that there is frequently confusion concerning the difference between it and related concepts such as people smuggling, migration and prostitution. The thesis examines the ways in which human trafficking has been conceptualised or framed in a specific national context- that of Lao PDR. Attention is given to the task of locating the major frames within which the issue has been situated, as well as considering the diagnoses and prognoses that the various approaches to trafficking suggest. The research considers which particular strands of trafficking discourse have become dominant in Lao PDR and the effect this has had on the kinds of trafficking interventions that have been undertaken in the country. The research is mainly qualitative and consists of an analysis of key texts found in the Lao trafficking discourse.

Diproline Templates as Folding Nuclei in Designed Peptides. Conformational Analysis of Synthetic Peptide Helices Containing Amino Terminal Pro-Pro Segments

The effect of N-terminal diproline segments in nucleating helical folding in designed peptides has been studied in two model sequences Piv-Pro-Pro-Aib-Leu-Aib-Phe-OMe (1) and Boc-Aib-Pro-Pro-Aib-Val-Ala-Phe-OMe (2). The structure of 1 in crystals, determined by X-ray diffraction, reveals a helical (RR) conformation for the segment residues 2 to 5, stabilized by one 4 -> 1 hydrogen bond and two 5 -> 1 interactions. The N-terminus residue, Pro(1) adopts a polyproline II (P-II) conformation. NMR studies in three different solvent systems support a conformation similar to that observed in crystals. In the apolar solvent CDCl3, NOE data favor the population of both completely helical and partially unfolded structures. In the former, the Pro-Pro segment adopts an alpha(R)-alpha(R) conformation, whereas in the latter, a P-II-alpha(R) structure is established. The conformational equilibrium shifts in favor of the P-II-alpha(R) structure in solvents like methanol and DMSO. A significant population of the Pro(1)- Pro(2) cis conformer is also observed. The NMR results are consistent with the population of at least three conformational states about Pro- Pro segment: trans alpha(R)-alpha(R), trans P-II-alpha(R) and cis P-II-alpha(R). Of these, the two trans conformers are in rapid dynamic exchange on the NMR time scale, whereas the interconversion between cis and trans form is slow. Similar results are obtained with peptide 2. Analysis of 462 diproline segments in protein crystal structures reveals 25 examples of the alpha(R)-alpha(R) conformation followed by a helix. Modeling and energy minimization studies suggest that both P-II-alpha(R) and alpha(R)-alpha(R) conformations have very similar energies in the model hexapeptide 1

Lyophilized disaccharides – the effect of water during storage

Nearly one fourth of new medicinal molecules are biopharmaceutical (protein, antibody or nucleic acid derivative) based. However, the administration of these compounds is not always that straightforward due to the fragile nature of aforementioned domains in GI-tract. In addition, these molecules often exhibit poor bioavailability when administered orally. As a result, parenteral administration is commonly preferred. In addition, shelf-life of these molecules in aqueous environments is poor, unless stored in low temperatures. Another approach is to bring these molecules to anhydrous form via lyophilization resulting in enhanced stability during storage. Proteins cannot most commonly be freeze dried by themselves so some kind of excipients are nearly always necessary. Disaccharides are commonly utilized excipients in freeze-dried formulations since they provide a rigid glassy matrix to maintain the native conformation of the protein domain. They also act as "sink"-agents, which basically mean that they can absorb some moisture from the environment and still help to protect the API itself to retain its activity and therefore offer a way to robust formulation. The aim of the present study was to investigate how four amorphous disaccharides (cellobiose, melibiose, sucrose and trehalose) behave when they are brought to different relative humidity levels. At first, solutions of each disaccharide were prepared, filled into scintillation vials and freeze dried. Initial information on how the moisture induced transformations take place, the lyophilized amorphous disaccharide cakes were placed in vacuum desiccators containing different relative humidity levels for defined period, after which selected analyzing methods were utilized to further examine the occurred transformations. Affinity to crystallization, water sorption of the disaccharides, the effect of moisture on glass transition and crystallization temperature were studied. In addition FT-IR microscopy was utilized to map the moisture distribution on a piece of lyophilized cake. Observations made during the experiments backed up the data mentioned in a previous study: melibiose and trehalose were shown to be superior over sucrose and cellobiose what comes to the ability to withstand elevated humidity and temperature, and to avoid crystallization with pharmaceutically relevant moisture contents. The difference was made evident with every utilized analyzing method. In addition, melibiose showed interesting anomalies during DVS runs, which were absent with other amorphous disaccharides. Particularly fascinating was the observation made with polarized light microscope, which revealed a possible small-scale crystallization that cannot be observed with XRPD. As a result, a suggestion can safely be made that a robust formulation is most likely obtained by utilizing either melibiose or trehalose as a stabilizing agent for biopharmaceutical freeze-dried formulations. On the other hand, more experiments should be conducted to obtain more accurate information on why these disaccharides have better tolerance for elevating humidities than others.

Texts "Con and Pro" : The Early Modern Medical Controversy over Tobacco

The habit of "drinking smoke" , meaning tobacco smoking, caused a true controversy in early modern England. The new substance was used both for its alleged therapeutic properties as well as its narcotic effects. The dispute over tobacco continues the line of written controversies which were an important means of communication in the sixteenth and seventeenth century Europe. The tobacco controversy is special among medical controversies because the recreational use of tobacco soon spread and outweighed its medicinal use, ultimately causing a social and cultural crisis in England. This study examines how language is used in polemic discourse and argumentation. The material consists of medical texts arguing for and against tobacco in early modern England. The texts were compiled into an electronic corpus of tobacco texts (1577 1670) representing different genres and styles of writing. With the help of the corpus, the tobacco controversy is described and analyzed in the context of early modern medicine. A variety of methods suitable for the study of conflict discourse were used to assess internal and external text variation. The linguistic features examined include personal pronouns, intertextuality, structural components, and statistically derived keywords. A common thread in the work is persuasive language use manifested, for example, in the form of emotive adjectives and the generic use of pronouns; the latter is especially pronounced in the dichotomy between us and them. Controversies have not been studied in this manner before but the methods applied have supplemented each other and proven their suitability in the study of conflictive discourse. These methods can also be applied to present-day materials.

From ‘Afflicted’ to Activists: Structural Violence and Climate Change Discourse in the States of Pernambuco and Paraíba in Northeast Brazil

This study approaches the problem of poverty in the hinterlands of Northeast Brazil through the concept of structural violence, linking the environmental threats posed by climate change, especially those related to droughts, to the broader social struggles in the region. When discussions about potentials and rights are incorporated into the problematic of poverty, a deeper insight is obtained regarding the various factors behind the phenomenon. It is generally believed that climate change is affecting the already marginalized and poor more than those of higher social standing, and will increasingly do so in the future. The data for this study was collected during a three month field work in the states of Pernambuco and Paraíba in Northeast Brazil. The main methods used were semi-structured interviews and participant observation, including attending seminars concerning climate change on the field. The focus of the work is to compare both layman and expert perceptions on what climate change is about, and question the assumptions about its effects in the future, mainly that of increased numbers of ‘climate refugees’ or people forced to migrate due to changes in climate. The focus on droughts, as opposed to other manifestations of climate change, arises from the fact that droughts are not only phenomena that develop over a longer time span than floods or hurricanes, but is also due to the historical persistence of droughts in the region, and both the institutional and cultural linkages that have evolved around it. The instances of structural violence that are highlighted in this study; the drought industry, land use, and the social and power relations present in the region, including those between the civil society, the state and the private agribusiness sector, all work against a backdrop of symbolic and moral realms of value production, where relations between the different actors are being negotiated anew with the rise of the climate change discourse. The main theoretical framework of the study consists of Johan Galtung’s and Paul Farmer’s theory of structural violence, Ulrich Beck’s theory of the risk society, and James Scott’s theory of everyday peasant resistance.

Tree mortality, fire scar formation and regeneration 8 years after low-intensity fire in managed Pinus sylvestris stands

Fire is an important driver of the boreal forest ecosystem, and a useful tool for the restoration of degraded forests. However, we lack knowledge on the ecological processes initiated by prescribed fires, and whether they bring about the desired restoration effects. The purpose of this study was to investigate the impacts of low-intensity experimental prescribed fires on four ecological processes in young commercial Scots pine (Pinus sylvestris) stands eight years after the burning. The processes of interest were tree mortality, dead wood creation, regeneration and fire scar formation. These were inventoried in twelve study plots, which were 30 m x 30 m in size. The plots belonged to two different stand age classes: 30-35 years or 45 years old at the time of burning. The study was partly a follow-up of study plots researched by Sidoroff et al. (2007) one year after burning in 2003. Tree mortality increased from 183 stems ha-1 in 2003 to 259 stems ha-1 in 2010, corresponding to 15 % and 21 % of stem number respectively. Most mortality was experienced in the stands of the younger age class, in smaller diameter classes and among species other than Scots pine. By 2010, the average mortality of Scots pine per plot was 18%, but varied greatly ranging from 0% to 63% of stem number. Delayed mortality, i.e. mortality that occurred between 2 and 8 years after fire, seemed to become more important with increasing diameter. The input of dead wood also varied greatly between plots, from none to 72 m3 ha-1, averaging at 12 m3 ha-1. The amount of fire scarred trees per plot ranged from none to 20 %. Four out of twelve plots (43 %) did not have any fire scars. Scars were on average small: 95% of scars were less than 4 cm in width, and 75% less than 40 cm in length. Owing to the light nature of the fire, the remaining overstorey and thick organic layer, regeneration was poor overall. The abundance of pine and other seedlings indicated a viable seed source existed, but the seedlings failed to establish under dense canopy. The number of saplings ranged from 0 to 12 333 stems ha-1. The results of this study indicate that a low intensity fire does not necessarily initiate the ecological processes of tree mortality, dead wood creation and regeneration in the desired scale. Fire scars, which form the basis of fire dating in fire history studies, did not form in all cases.

Social and material deprivation among youth in Finland : causes, consequences, and coping.

Background: Social and material deprivation is associated with poor health, decreased subjective well-being, and limited opportunities for personal development. To date, little is known about the lived experiences of Finnish low-income youths and the general purpose of this study is to fill this gap. Despite the extensive research on socioeconomic income disparities, only a few scholars have addressed the question of how low socioeconomic position is experienced by disadvantaged people themselves. Little is known about the everyday social processes that lead to decreased well-being of economically and socially disadvantaged citizens. Data: The study is based on the data of 65 autobiographical essays written by Finnish low-income youths aged 14-29 (M=23.51, SD=3.95). The research data were originally collected in a Finnish nationwide writing contest “Arkipäivän kokemuksia köyhyydestä” [Everyday Experiences of Poverty] between June and September of 2006. The contest was partaken by 850 Finnish writers. Methods and key concepts: Autobiographical narratives (N=65) of low-income youths were analyzed based on grounded theory methodology (GTM). The analysis was not built on specific pre-conceived categorizations; it was guided by the paradigm model and so-called “sensitizing concepts”. The concepts this study utilized were based on the research literature on socioeconomic inequalities, resilience, and coping. Socioeconomic inequalities refer to unequal distribution of resources, such as income, social status, and health, between social groups. The concept of resilience refers to an individual’s capacity to cope despite existing risk factors and conditions that are harmful to health and well-being. Coping strategies can be understood as ways by which a person tries to cope with psychological stress in a situation where internal or externals demands exceed one’s resources. The ways to cope are cognitive or behavioral efforts by which individual tries to relieve the stress and gain new resources. Lack of material and social resources is associated with increased exposure to health-related stressors during the life-course. Aims: The first aim of this study is to illustrate how youths with low socioeconomic status perceive the causes and consequences of their social and material deprivation. The second aim is to describe what kind of coping strategies youths employ to cope in their everyday life. The third aim is to build an integrative conceptual framework based on the relationships between causes, consequences, and individual coping strategies associated with deprivation. The analysis was carried out through systematic coding and orderly treatment of the data based on the grounded theory methodology. Results: Finnish low-income youths attributed the primary causes of deprivation to their family background, current socioeconomic status, sudden life changes, and contextual factors. Material and social deprivation was associated with various kinds of negative psychological, social, and material consequences. Youths used a variety of coping strategies that were identified as psychological, social, material, and functional-behavioral. Finally, a conceptual framework was formulated to link the findings together. In the discussion, the results were compared and contrasted to the existing research literature. The main references of the study were: Coping: Aldwin (2007); Lazarus & Folkman (1984); Hobfoll (1989, 2001, 2002). Deprivation: Larivaara, Isola, & Mikkonen (2007); Lister (2004); Townsend (1987); Raphael (2007). Health inequalities: Dahlgren & Whitehead (2007); Lynch. et al. (2000); Marmot & Wilkinson (2006); WHO (2008). Methods: Charmaz (2006); Flick (2009); Strauss & Corbin (1990). Resilience: Cutuli & Masten (2009); Luthar (2006).

Long-Term Excess Mortality after Aneurysmal Subarachnoid Hemorrhage

Objective There is high case-fatality rate and loss of productive life-years related to aneurysmal subarachnoid hemorrhage (aSAH) but little data on long-term survival of SAH patients. We aim to evaluate long-term excess mortality and related risk factors after aSAH. Methods One year survivors (n=3080) after aSAH from Department of Neurosurgery in Helsinki between 1980 and 2007 were reviewed for this retrospective follow-up study. Follow-up started one year after SAH and continued until death or the end of 2008 (36 960 patient-years). Mortality and relative survival ratio (RSR) were compared with matched general population. Results After 20 years, survivors of aSAH showed 18% excess mortality compared to general population. Risk factors included: old age; poor preoperative clinical condition; conservative aneurysm treatment; multiple aneurysms; and unfavourable clinical outcome at 3 months. Conclusion Even after initially favourable recovery, patients with aSAH experience excess mortality in the long run. Cardiovascular and cerebrovascular diseases are prominent in this population.
