Global, regional, and national comparative risk assessment of 79 behavioural, environmental and occupational, and metabolic risks or clusters of risks in 188 countries, 1990–2013: a systematic analysis for the Global Burden of Disease Study 2013

Background The Global Burden of Disease, Injuries, and Risk Factor study 2013 (GBD 2013) is the first of a series of annual updates of the GBD. Risk factor quantification, particularly of modifiable risk factors, can help to identify emerging threats to population health and opportunities for prevention. The GBD 2013 provides a timely opportunity to update the comparative risk assessment with new data for exposure, relative risks, and evidence on the appropriate counterfactual risk distribution. Methods Attributable deaths, years of life lost, years lived with disability, and disability-adjusted life-years (DALYs) have been estimated for 79 risks or clusters of risks using the GBD 2010 methods. Risk–outcome pairs meeting explicit evidence criteria were assessed for 188 countries for the period 1990–2013 by age and sex using three inputs: risk exposure, relative risks, and the theoretical minimum risk exposure level (TMREL). Risks are organised into a hierarchy with blocks of behavioural, environmental and occupational, and metabolic risks at the first level of the hierarchy. The next level in the hierarchy includes nine clusters of related risks and two individual risks, with more detail provided at levels 3 and 4 of the hierarchy. Compared with GBD 2010, six new risk factors have been added: handwashing practices, occupational exposure to trichloroethylene, childhood wasting, childhood stunting, unsafe sex, and low glomerular filtration rate. For most risks, data for exposure were synthesised with a Bayesian meta-regression method, DisMod-MR 2.0, or spatial-temporal Gaussian process regression. Relative risks were based on meta-regressions of published cohort and intervention studies. Attributable burden for clusters of risks and all risks combined took into account evidence on the mediation of some risks such as high body-mass index (BMI) through other risks such as high systolic blood pressure and high cholesterol. Findings All risks combined account for 57·2% (95% uncertainty interval [UI] 55·8–58·5) of deaths and 41·6% (40·1–43·0) of DALYs. Risks quantified account for 87·9% (86·5–89·3) of cardiovascular disease DALYs, ranging to a low of 0% for neonatal disorders and neglected tropical diseases and malaria. In terms of global DALYs in 2013, six risks or clusters of risks each caused more than 5% of DALYs: dietary risks accounting for 11·3 million deaths and 241·4 million DALYs, high systolic blood pressure for 10·4 million deaths and 208·1 million DALYs, child and maternal malnutrition for 1·7 million deaths and 176·9 million DALYs, tobacco smoke for 6·1 million deaths and 143·5 million DALYs, air pollution for 5·5 million deaths and 141·5 million DALYs, and high BMI for 4·4 million deaths and 134·0 million DALYs. Risk factor patterns vary across regions and countries and with time. In sub-Saharan Africa, the leading risk factors are child and maternal malnutrition, unsafe sex, and unsafe water, sanitation, and handwashing. In women, in nearly all countries in the Americas, north Africa, and the Middle East, and in many other high-income countries, high BMI is the leading risk factor, with high systolic blood pressure as the leading risk in most of Central and Eastern Europe and south and east Asia. For men, high systolic blood pressure or tobacco use are the leading risks in nearly all high-income countries, in north Africa and the Middle East, Europe, and Asia. For men and women, unsafe sex is the leading risk in a corridor from Kenya to South Africa. Interpretation Behavioural, environmental and occupational, and metabolic risks can explain half of global mortality and more than one-third of global DALYs providing many opportunities for prevention. Of the larger risks, the attributable burden of high BMI has increased in the past 23 years. In view of the prominence of behavioural risk factors, behavioural and social science research on interventions for these risks should be strengthened. Many prevention and primary care policy options are available now to act on key risks.

The ascidian natural product eusynstyelamide B is a novel topoisomerase II poison that induces DNA damage and growth arrest in prostate and breast cancer cells

As part of an anti-cancer natural product drug discovery program, we recently identified eusynstyelamide B (EB), which displayed cytotoxicity against MDA-MB-231 breast cancer cells (IC50 = 5 μM) and induced apoptosis. Here, we investigated the mechanism of action of EB in cancer cell lines of the prostate (LNCaP) and breast (MDA-MB-231). EB inhibited cell growth (IC50 = 5 μM) and induced a G2 cell cycle arrest, as shown by a significant increase in the G2/M cell population in the absence of elevated levels of the mitotic marker phospho-histone H3. In contrast to MDA-MB-231 cells, EB did not induce cell death in LNCaP cells when treated for up to 10 days. Transcript profiling and Ingenuity Pathway Analysis suggested that EB activated DNA damage pathways in LNCaP cells. Consistent with this, CHK2 phosphorylation was increased, p21CIP1/WAF1 was up-regulated and CDC2 expression strongly reduced by EB. Importantly, EB caused DNA double-strand breaks, yet did not directly interact with DNA. Analysis of topoisomerase II-mediated decatenation discovered that EB is a novel topoisomerase II poison.

Spatial B-jump at sudden channel enlargements with abrupt drop

An analytical and experimental study of the hydraulic jump in stilling basins with abrupt drop and sudden enlargement, called the spatial B-jump here, is carried out for finding the sequent depth ratio and resulting energy dissipation. The spatial B-jump studied has its toe downstream of the expansion section, and the stream lines at the toe are characterized by downward curvature. An expression is obtained for the sequent depth ratio based on the momentum equation with suitable assumptions for the extra pressure force term because of the abrupt drop in the bed and sudden enlargement in the basin width. Predictions compare favorably with experiments. It is shown that the spatial B-jump needs less tailwater depth, thereby enhancing the stability of the jump when compared either with spatial jump, which forms in sudden expanding channels, or with B-jump, which forms in a channel with an abrupt drop in bed. It is also shown that there is a significant increase in relative energy loss for the spatial B-jump compared to either the spatial jump or B-jump alone.

B- and T-cell epitopes of tropomyosin, the major shrimp allergen

Seafood allergy is often encountered on ingestion of crustaceans such as shrimp, lobster, crab, and crayfish (1). On eating cooked shrimp, sensitive individuals experience a wide spectrum of reactions ranging from abdominal discomfort to anaphylaxis. The presence of cross-reacting heat-stable allergens in crustacean food was first recognized by Hoffman et al. (2) and Lehrer et al. (3). Subsequently, the major allergen was isolated and characterized from the shrimp species Paneaus indicus (Pen i 1) (4) and I? aztecm (Pen a 1) (5). Pen i 1 (originally designated Sa-TI) and Pen a 1, with mol. mass of 34 and 36 kDa, respectively, contain 301 and 312 amino-acid residues with a predominance of gluta- mate/glutamine and asparatate/asparagine.

Effect of microstructure on the mechanical behavior of b-modified ti-6al-4v alloys

Small additions of B to Titanium alloys refine the as-cast microstructure significantly and hence improve their mechanical performance. In this work, tensile, fracture and fatigue properties of the as-cast and HIPed Ti-6Al-4V alloy with hypoeutectic wt.% of B additions have been examined, with particular emphasis on identifying the microstructural length scale that controls the mechanical properties of these alloys.

Polymorphism in B-DNA - X-ray-Diffraction Studies on Li-DNA Fibers

From X-ray diffraction studies it is generally believed that B-DNA has the structural parameters n = 10 and h = 3.4 Å. However, for the first time we report that polymorphism in the B-form can be observed in DNA fibres. This was achieved by the precise control of salt and humidity in fibres and by the application of the precession method of X-ray diffraction to DNA fibres. The significant result obtained is that n = 10 is not observed for crystalline fibre patterns. In fact, n = 10 and h = 3.4 Å are not found to occur simultaneously. Instead, a range of values, n = 9.6–10.0 and h = 3.35 Å–3.41 Å is observed.

There are no unusual bond distances or angles. The triazole and two phenyl rings are planar. On the basis of packing considerations the possibility of intermolecular interactions playing a role in the reactivity of the starting material is ruled out.

Conformational flexibility in androgenic steroids - the structure of a new form of (+)-17-beta-hydroxy-19-nor-4-androsten-3-one (19-nortestosterone), c18h26o2

The structure and conformation of a second crystalline modification of 19-nortestosterone has been determined by X-ray methods. M r = 274, monoclinic P2 l, a=9.755(2), b= 11.467(3), c= 14.196(3)/L fl=101.07(2) ° , V=1558.4 (8) A 3, Z=4, Ox= I. 168 g cm -3, Mo Ka, 2 = 0.7107 ,/k, ~ = 0.80 cm -l, F(000) = 600, T= 300 K. R = 0.060 for 2158 observed reflections. The two molecules in the asymmetric unit show significant differences in the A-ring conformation from that of the previously reported form of the title compound [Precigoux, Busetta, Courseille & Hospital (1975). Acta Cryst. B31, 1527-1532]. The l a,2fl-half-chair conformation of the A ring increases its conformational freedom compared with testosterone.

Critical Cation Balance In B-]Z Transition - Role Of Li+

The sodium salt of poly(dG-dC) is known to exhibit a B + Z transition in the presence of various cations and 60% alcohol. We here show that the lithium salt of poly(dG-dC) does not undergo B 4 Z transition in the presence of 60% alcohol since Li’ with its large hydration shell cannot stabilize the Z-form. On the other hand, high concentrations of Mg2* or micromolar concentrations of the cobalt hexamine complex which are known to stabilize the Z-form can compete with Li+ for charge neutraIization and hence bring about a B--t Z transition in the same polymer. From the model building studies the mode of action of the cobalt-hexamine complex in stabilizing the Z-form is postulated.

Fibre diffraction of lithium DNA shows structural variability and deviation from a regular helical structure for the B-form

Recently, reports have appeared which show structural variations in B-DNA and indicate deviations from a uniform helical structure. We report for the first time that these indications are also present in the B-form fibre diffraction patterns for the lithium salt of natural DNA. We have used an improved method of controlling the salt concentration in the fibres. Our results are based on the appearance and disappearance of meridional reflections on different layer lines depending upon the salt.

Rossijskaja Karelija i karely v imperskoi politike Rossii, 1905-1917

Russian Karelians were one of the small peasant nations of the Russian Empire that began to identify themselves as nations during the late imperial period. At that historical moment Russian Karelia fell between an economically undeveloped empire and the rapidly modernizing borderland of Finland. The economic and cultural lure of Finland drew Karelians into the Finnish camp. This attraction was seen as a challenge to Russia and influenced the straggle between Russia and Finland for the Karelians. This struggle was waged from 1905 to 1917. This work is focused on the beginning stage of the struggle, its various phases, and their results. The confrontation extended into different dimensions (economic, political, ideological, church and cultural politics) and occurred on two levels: central and regional. Countermeasures against local nationalisms developed much earlier both in Russia and in other empires for use were also used in the Russian Karelian case. Economic policies were deployed to try to make relations with Russia more alluring for Karelians and to improve their economic condition. However, these efforts produced only minimal results due to the economic weakness of the empire and a lack of finances. Fear of the economic integration of the Karelians and Finns, which would have stimulated the economy of the Karelia, also hindered these attempts. The further development of the Orthodox Church, the schools and the zemstvos in Karelia yielded fewer results than expected due to the economic underdevelopment of the region and the avoidance of the Finnish language. Policizing measures were the most successfull, as all activities in Russian Karelia by the Finns were entirely halted in practice. However, the aspiration of Russian Karelians to integrate their home districts with Finland remained a latent force that just waited for an opportunity to push to the surface again. Such a chance materialized with the Russian revolution. The Karelian question was also a part of Russian domestic political confrontation. At the and of the 1800s, the Russian nationalist right had grown strong and increasingly gained the favor of the autocracy. The right political forces exploited the Karelian question in its anti-Finnish ideology and in its general resistance to the national emancipation of the minority peoples of Russia. A separate ideology was developed, focusing on the closeness of Karelians to the "great Russian people." Simultaneously, this concept found a place in the ultramonarchist myth of the particularly close connection between the people and tsar that was prominent in the era of Nicholas II. This myth assigned the Karelians a place amongst the "simple people" faithful to the tsar.

Phylogeny of the Rhyparini and the new tribe Stereomerini, with descriptions of new genera and species (Coleoptera; Scarabaeidae; Aphodiinae)

A new tribe, the Stereomerini, is established for four unusual genera: Stereomera Arrow, Termitaxis Krikken, Australoxenella n.gen., and Bruneixenus n.gen. The previously described genera are monotypic, as is Bruneixenus, the type species being B. squamosus n.sp. from Brunei. Australoxenella contains two new species, A. humptydooensis, type species, and A. bathurstensis, both from the Northern Territory, Australia. The relationships of the new tribe are analyzed and compared with the most closely related tribe, the Rhyparini, in the Aphodiinae. The tribe Rhyparini is redefined, and the genus Notocaulus Quedenfeldt is transferred to the Eupariini. A key to genera in both the Stereomerini and the Rhyparini is presented, important characters are illustrated, a cladogram is given, and convergence is discussed.

Competing A-site and B-site driven ferroelectric instabilities in the (1-x)PbTiO3-(x)BiAlO3 system

The system (1-x)PbTiO3-(x)BiAlO3 has been investigated with regard to its solid solubility, crystal structure, microstructure, and ferroelectric transition. The unit cell volume and the tetragonality exhibit anomalous behavior near x=0.10. The Curie point (T-C) of PbTiO3 was however found to be nearly unchanged. The study seems to suggest that the decrease in the stability of the ferroelectric state due to dilution of the Ti-sublattice by smaller sized Al+3 ions is compensated by the increase in the ferroelectric stability by the Bi+3 ions.

Three new Lasiodiplodia spp. from the tropics, recognized based on DNA sequence comparisons and morphology

Botryosphaeria rhodina (anamorph Lasiodiplodia theobromae) is a common endophyte and opportunistic pathogen on more than 500 tree species in the tropics and subtropics. During routine disease surveys of plantations in Australia and Venezuela several isolates differing from L. theobromae were identified and subsequently characterized based upon morphology and ITS and EF1-a nucleotide sequences. These isolates grouped into three strongly supported clades related to but different from the known taxa, B. rhodina and L. gonubiensis, These have been described here as three new species L. venezuelensis sp. nov., L. crassispora sp. nov. and L. rubropurpurea sp. nov. The three could be distinguished easily from each other and the two described species of Lasiodiplodia, thus confirming phylogenetic separations. Furthermore all five Lasiodiplodia spp. now recognized separated from Diplodia spp. and Dothiorella spp. with 100% bootstrap support.

Kesken jäänyt vallankumous : Sosiaalinen mobilisaatio Helsingissä vuoden 1905 suurlakosta Viaporin kapinaan 1906

Tutkielmassani käsittelen vuoden 1905 suurlakon ja Viaporin kapinan välistä aikaa vallankumouksellisena prosessina Helsingissä. Miten vallankumouksellisuus ilmeni suurlakon aikana ja sen jälkeen Helsingissä? Miten tavalliset työläiset reagoivat tapahtumiin? Metodisina apuvälineinä minulla on ensinnäkin Charles Tillyn määritelmä vallankumoukselliselle tapahtumalle. Keskeistä tälle määritelmälle on, että vallankumouksellista tapahtumaa pitää tutkia sen lähtökohdista käsin eikä lopputuloksen kautta. Vallankumouksellinen tilanne syntyy, kun olemassa oleva hallitus saa kilpailijan ja vastaavasti se on ohi, kun jompikumpi jää jäljelle. Toiseksi apunani ovat olleet sosiaalihistorialliset tutkimukset Venäjän vallankumouksesta, joissa aihetta käsitellään ruohonjuuritason näkökulmasta. Tällöin polttopisteessä ovat lakot ja niiden aikana esitetyt vaatimukset. Oleellista näistä tutkimuksissa on, ettei työläisiä nähdä tahdottomana massana, joka sokeasti tottelee poliittisten johtajien käskyjä. Työläisillä oli omia, lähinnä ammatillisia vaatimuksia, jotka ilmensivät toisaalta huolta jokapäiväisestä toimeentulosta ja toisaalta ne heijastivat demokraattisten vaatimusten ulottamista laajemmalle kuin pelkästään valtiolliselle tasolle eli myös työpaikoille. Suurlakon aikana Helsingin työläiset johtivat käytännössä kaupungin julkista elämää. Vallan keskuksena toimi kansallislakon keskuskomitea. Näkyvintä valtaa käytti kansalliskaarti. Kaarti toimi vahvana poliisivoimana koko lakon ajan. Se pyrki kontrolloimaan liikennettä ja kauppaa sekä sensuroimaan muiden tahojen tiedonvälitystä. Raittiusväellä oli myös oma kaartin osasto, jonka avulla kaupunkiin säädettiin kieltolaki sekä kiellettiin prostituutio. Keskeinen elementti lakon onnistumisen kannalta oli niinikään avustustoiminnan järjestäminen lakon vuoksi hätään joutuneille. Näin turvattiin, ettei lakkorintamassa sattuisi ennenaikaisia repeämiä. Suurlakon jälkeen työväestö aktivoitui ennennäkemättömällä tavalla. Lakkojen lukumäärä ja niihin osallistuneiden työläisten määrä moninkertaistui. SDP:n virallinen tavoite eli poliittinen kansalaisuus ei riittänyt työläisjoukoille, vaan lakoilla pyrittiin saamaan aikaiseksi demokraattinen yhteiskunta laajemminkin. Lyhytikäisiksi jääneet työehtosopimukset eivät tilannetta korjanneet. Demokratia saatiin poliittisella tsolla, mutta ruohonjuurinäkökulmasta uudistukset jäivät kesken ja tyytymättömyys säilyi. Tässä mielessä työväenliike ei integroitunut yhteiskuntaan. Suomessa vallankumouksellinen toivo asetettiin Venäjän vallankumoustapahtumien etenemiseen. Suomalaisen radikalismin päätepisteenä voi pitää epäonnistunuttta Viaporin kapinaa, johon osallistui myös suomalaisia punakaartilaisia. Punakaartilaiset olivat suurelta osin nuoria, muualta Helsinkiin muuttaneita ja vähän järjestökokemusta omaavia henkilöitä. Nuoruus, juurettomuus ja liittyminen työväentyöväenpuolueeseen tai sen järjestöihin vasta perustamisvaiheen 1899-1903 jälkeen olivatkin leimallisia piirteitä radikaalien aineksien keskuudessa. Tutkielmassani osoitan, että ruohonjuuritason tutkimuksella voidaan kuvaa vuosisadan alun työläisistä, heidän toiveistaan ja haluistaan täsmentää. Vuosien 1905 ja 1906 poliittisessa murroksessa oli myös ammatillisilla seikoilla tärkeä sija työväestön pyrkimyksissä. Ne osoittavat omalta osaltaan työläisten vallankumouksellisia ja radikaaleja vaatimuksia. Punakaartilaisradikalismi oli läheistä sukua tälle toiminnalle. Avainsanat: Sosiaalihistoria, vallankumous, työväenliike, suurlakko 1905, Viaporin kapina.
