Sika- ja siipikarjatalouden rakennemuutoskorvaus C-tukialueella

Sika- ja siipikarjatilojen määrä Suomessa on vähentynyt koko EU-jäsenyyden ajan tuotannon keskittyessä yhä suurempiin yksiköihin. Tuotantomäärät ovat kasvaneet, mutta viljelijöiden tulotaso on alentunut, joten maatalouden ulkopuoliset ammatit houkuttelevat luopumaan eläinten pidosta tai maataloudesta kokonaan. Sika- ja siipikarjatalouden rakennemuutoksen taloudellisena kannustimena otettiin vuonna 2009 käyttöön sika- ja siipikarjatalouden rakennemuutoskorvaus, jota maksetaan kompensaationa sika- ja siipikarjataloudesta luopuville viljelijöille. Tämän työn tarkastelukohteena on rakennemuutoskorvaus C-tukialueella, jossa yksinään on lähes yhtä paljon sika- ja siipikarjatiloja kuin A- ja B-alueilla yhteensä. Tutkimuksen tavoitteena on selvittää, millaiset sika- ja siipikarjatilat sekä koko C-alueella että C-alueen eri osissa ovat hakeneet rakennemuutoskorvausta ja miten tilat ovat alueellisesti sijoittuneet. Maatalouden rakennepolitiikalla pyritään vaikuttamaan maatalouden yhteiskunnalliseen rakenteeseen. Rakennepoliittisilla toimilla pyritään vähentämään viljelijöiden ja tilojen määrää, jolloin maataloustulo jakaantuu pienemmälle viljelijämäärälle taaten heille suuremmat tulot. Maatalouden rakennemuutosta tapahtuu, kun maatalouden rakenteessa tapahtuu tietyllä aikavälillä muutos. Rakennemuutoksessa ja -kehityksessä on alueellisia eroja. Aluetaloustiede pyrkii selittämään, mistä alueelliset erot johtuvat ja miksi alueet erilaistuvat. Suomessa eri maakunnilla on eroja ja omia alueellisia ominaispiirteitään, joilla on suuri merkitys alueen työllisyyteen ja väestön sijoittumiseen alueella. Eri maakunnissa työllisyystilanne on vaihteleva, mutta joka maakunnassa on kuitenkin työvoimapulaa useissa sellaisissa ammateissa, joihin eläinten tai tilan pidon lopettavien viljelijöiden olisi mahdollista työllistyä. Sika- ja siipikarjatalouden rakennemuutoskorvaus on kansallinen kotieläintuki, jota maksetaan tilakohtaisen viitemäärän perusteella tiloille, jotka ovat juuri lopettaneet sika- ja siipikarjatuotantonsa tai aikovat sen lopettaa. Korvausta on voitu maksaa tukiehdot täyttävälle tuenhakijalle joko vuosina 2009–2010 tai vuosina 2010–2011 ja sen maksimimäärä on tilaa kohden enintään 20000 euroa vuodessa. Kahden korvausvuoden jälkeen tilan viitemäärä lakkautetaan ja sen jälkeen tilalle ei enää makseta sika- ja siipikarjatalouden tukia. Tilan on kuitenkin edelleen mahdollista jatkaa sika- ja siipikarjatuotantoaan markkinaehtoisena. Tutkimuksen aineisto on 389 tilan tiedot sisältävä Tiken raportti tukityypin 1612 (sika- ja siipikarjatalouden rakennemuutoskorvaus, pohjoinen) tukihakutiedoista vuodelta 2010. Tutkimusote oli kvantitatiivinen ja koska havaintoaineisto kattaa kaikki C-alueen korvauksenhakijat, tehtiin tutkimus kokonaistutkimuksena. Tutkimustulosten mukaan 63 % korvausta hakeneista tiloista sijoittuu C1-alueelle ja 54 % Etelä-Pohjanmaalle ja Pohjanmaalle. Kuntatasolla eniten rakennemuutoskorvaustiloja oli Närpiössä. C-alueella tuenhakijat olivat iältään 20–71-vuotiaita. Hakijoista 62 % harjoitti päätuotantosuuntanaan viljanviljelyä ja peltoalaa kaikilla hakijoilla oli hallinnassaan lähes 16000 ha. Rakennemuutoskorvausta maksettiin C-alueella yhteensä yli 2,3 miljoonaa euroa. Kun rakennemuutoskorvauksen viitemäärät kahden korvausvuoden jälkeen lakkautetaan, poistuu tuo-tannosta yli 9600 ey. Sekä C-alueella että kaikki ELY-keskukset huomioiden oli korvauksenhakijoita kaikkia ikäluokkia tarkasteltaessa eniten 50–59-vuotiaissa. Eniten hakijoita oli viitemääräluokassa 10,01–20 ey ja viljelyalaluokassa 25,01–40 ha, vähiten luokissa 40,01–50 ey ja 50,01 ey tai enemmän sekä 150,01 ha tai enemmän. Yleisin maksuluokka oli 3000,01–4500 euroa, harvinaisin 15000,01–20000 euroa. Rakennemuutoskorvauksella saavutettuja hyötyjä ja kustannuksia on toistaiseksi vaikea määritellä, koska vuoden 2011 maksatus on vielä kesken.

Excitation and correlation of N-14 overtone transitions and measurement of heteronuclear dipolar coupling using DAPT

For studying systems containing nitrogen, limited use of N-14 NMR spectroscopy has been made because of the large quadrupolar interaction experienced by the N-14 nucleus and the absence of a central transition. To overcome the above problem, use of overtone spectroscopy has been suggested. Though this approach has limited applicability for powder samples due to second order quadrupole broadening, it is useful for studying oriented samples and single crystals. Here, we demonstrate the use of the recently proposed dipolar assisted polarization transfer (DAPT) pulse scheme for exciting the overtone transitions. The pulse sequence may also be utilized as a two-dimensional experiment to obtain H-1-N-14 dipolar couplings and H-1 chemical shifts. (C) 2010 Elsevier B.V. All rights reserved.

Formation of a G-quadruplex at the BCL2 major breakpoint region of the t(14;18) translocation in follicular lymphoma

The t(14;18) translocation in follicular lymphoma is one of the most common chromosomal translocations. Most breaks on chromosome 18 are located at the 3'-UTR of the BCL2 gene and are mainly clustered in the major breakpoint region (MBR). Recently, we found that the BCL2 MBR has a non-B DNA character in genomic DNA. Here, we show that single-stranded DNA modeled from the template strand of the BCL2 MBR, forms secondary structures that migrate faster on native PAGE in the presence of potassium, due to the formation of intramolecular G-quadruplexes. Circular dichroism shows evidence for a parallel orientation for G-quadruplex structures in the template strand of the BCL2 MBR. Mutagenesis and the DMS modification assay confirm the presence of three guanine tetrads in the structure. 1H nuclear magnetic resonance studies further confirm the formation of an intramolecular G-quadruplex and a representative model has been built based on all of the experimental evidence. We also provide data consistent with the possible formation of a G-quadruplex structure at the BCL2 MBR within mammalian cells. In summary, these important features could contribute to the single-stranded character at the BCL2 MBR, thereby contributing to chromosomal fragility.

Comparison of the ultrafast to slow time scale dynamics of three liquid crystals in the isotropic phase

The dynamics of three liquid crystals, 4'(pentyloxy)-4-biphenylcarbonitrile (5-OCB), 4'-pentyl-4-biphenylcarbonitrile (5-CB), and 1-isothiocyanato-(4-propylcyclohexyl)benzene (3-CHBT), are investigated from very short time (similar to1 ps) to very long time (>100 ns) as a function of temperature using optical heterodyne detected optical Kerr effect experiments. For all three liquid crystals, the data decay exponentially only on the longest time scale (> several ns). The temperature dependence of the long time scale exponential decays is described well by the Landau-de Gennes theory of the randomization of pseudonematic domains that exist in the isotropic phase of liquid crystals near the isotropic to nematic phase transition. At short time, all three liquid crystals display power law decays. Over the full range of times, the data for all three liquid crystals are fit with a model function that contains a short time power law. The power law exponents for the three liquid crystals range between 0.63 and 0.76, and the power law exponents are temperature independent over a wide range of temperatures. Integration of the fitting function gives the empirical polarizability-polarizability (orientational) correlation function. A preliminary theoretical treatment of collective motions yields a correlation function that indicates that the data can decay as a power law at short times. The power law component of the decay reflects intradomain dynamics. (C) 2002 American Institute of Physics.

Interplay between NS3 protease and human La protein regulates translation-replication switch of Hepatitis C virus

HCV NS3 protein plays a central role in viral polyprotein processing and RNA replication. We demonstrate that the NS3 protease (NS3(pro)) domain alone can specifically bind to HCV-IRES RNA, predominantly in the SLIV region. The cleavage activity of the NS3 protease domain is reduced upon HCV-RNA binding. More importantly, NS3(pro) binding to the SLIV hinders the interaction of La protein, a cellular IRES-trans acting factor required for HCV IRES-mediated translation, resulting in inhibition of HCV-IRES activity. Although overexpression of both NS3(pro) as well as the full length NS3 protein decreased the level of HCV IRES mediated translation, replication of HCV replicon RNA was enhanced significantly. These observations suggest that the NS3(pro) binding to HCV IRES reduces translation in favor of RNA replication. The competition between the host factor (La) and the viral protein (NS3) for binding to HCV IRES might regulate the molecular switch from translation to replication of HCV.

Growth and ferroelectric properties of Bi2VO5.5 thin films with metallic LaNiO3 electrodes

Novel ferroelectric bismuth vanadate, Bi2VO5.5 (BVO), thin films have been grown between lattice matched metallic LaNiO3 (LNO) layers deposited on SrTiO3 (STO) by the pulsed laser deposition technique. LNO/BVO/LNO/STO and Au/BVO/LNO/STO trilayer structures exhibited c���oriented (001) growth of BVO. LNO has been found to be a good metallic electrode with sheet resistance ∼20 Ω in addition to aiding c‐axis oriented BVO growth. The dielectric constant, ϵr of LNO/BVO/LNO/STO, at 300 K was about 12. However, when an Au electrode was used on top of BVO/LNO/STO film, it showed a significant improvement in the dielectric constant (ϵr=123). The ferroelectric properties of BVO thin films have been confirmed by hysteresis behavior with a remnant polarization, Pr=4.6×10−8 C/cm2 and coercive field, Ec=23 kV/cm at 300 K.

IN-VITRO CYTOTOXICITY AND CELL CYCLE ANALYSIS OF TWO NOVEL BIS-1, 2, 4-TRIAZOLE DERIVATIVES: 1,4-BIS[5-(5-MERCAPTO-1,3,4-OXADIAZOL-2-yl-METHYL)-THIO-4-(p-TOLYL)-1, 2,4-TRIAZOL-3-yl]-BUTANE (MNP-14) AND 1,4-BIS[5-(CARBETHOXY-METHYL)-THIO-4-(p-ETHOXY PHENYL)-1,2,4-TRIAZOL-3-yl]-BUTANE (MNP-16)

In the present study, we have tested the cytotoxic and DNA damage activity of two novel bis-1,2,4 triazole derivatives, namely 1,4-bis[5-(5-mercapto-1,3,4-oxadiazol-2-yl-methyl)-thio4-(p-tolyl)-1,2 ,4-triazol-3-yl]-butane (MNP-14) and 1,4-bis[5-(carbethoxy-methyl)-thio-4-(p-ethoxy phenyl) -1,2,4-triazol-3-yl]-butane (MNP-16). The effect of these molecules on cellular apoptosis was also determined. The in-vitro cytotoxicity was evaluated by a 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT) assay as well as Trypan blue dye exclusion methods against human acute lymphoblastic leukemia (MOLT4) and lung cancer cells (A549). Our results showed that MNP-16 induced significant cytotoxicity (IC50 of 3-5 mu M) compared with MNP-14. The cytotoxicity induced by MNP-16 was time and concentration dependent. The cell cycle analysis by flow cytometry (fluorescence-activated cell sorting [FACS]) revealed that though there was a significant increase in the apoptotic population (sub-G1 phase) with an increased concentration of MNP-14 and 16, there was no cell cycle arrest. Further, the comet assay results indicated considerable DNA

Mechanism of Fragility at BCL2 Gene Minor Breakpoint Cluster Region during t(14;18) Chromosomal Translocation

The t(14;18) translocation in follicular lymphoma is one of the most common chromosomal translocations. Breaks in chromosome 18 are localized at the 3'-UTR of BCL2 gene or downstream and are mainly clustered in either the major breakpoint region or the minor breakpoint cluster region (mcr). The recombination activating gene (RAG) complex induces breaks at IgH locus of chromosome 14, whereas the mechanism of fragility at BCL2 mcr remains unclear. Here, for the first time, we show that RAGs can nick mcr; however, the mechanism is unique. Three independent nicks of equal efficiency are generated, when both Mg2+ and Mn2+ are present, unlike a single nick during V(D)J recombination. Further, we demonstrate that RAG binding and nicking at the mcr are independent of nonamer, whereas a CCACCTCT motif plays a critical role in its fragility, as shown by sequential mutagenesis. More importantly, we recapitulate the BCL2 mcr translocation and find that mcr can undergo synapsis with a standard recombination signal sequence within the cells, in a RAG-dependent manner. Further, mutation to the CCACCTCT motif abolishes recombination within the cells, indicating its vital role. Hence, our data suggest a novel, physiologically relevant, nonamer-independent mechanism of RAG nicking at mcr, which may be important for generation of chromosomal translocations in humans.

NMR Analysis of Cross Strand Aromatic Interactions in an 8 Residue Hairpin and a 14 Residue Three Stranded beta-Sheet Peptide

Cross strand aromatic interactions between a facing pair of phenylalanine residues in antiparallel beta-sheet structures have been probed using two structurally defined model peptides. The octapeptide Boc-(LFVPPLFV)-P-D-P-L-OMe (peptide 1) favors the beta-hairpin conformation nucleated by the type II' beta-turn formed by the (D)Pro-(L)Pro segment, placing Phe2 and Phe7 side chains in proximity. Two centrally positioned (D)Pro-(L)Pro segments facilitate the three stranded beta-sheet formation in the 14 residue peptide Boc-LFV(D)P(L)PLFVA(D)P(L)PLFV-OMe (peptide 2) in which the Phe2/Phe7 orientations are similar to that in the octapeptide. The anticipated folded conformations of peptides 1 and 2 are established by the delineation of intramolecularly hydrogen bonded NH groups and by the observation of specific cross strand NOEs. The observation of ring current shifted aromatic protons is a diagnostic of close approach of the Phe2 and Phe7 side chains. Specific assignment of aromatic proton resonances using HSQC and HSQC-TOCSY methods allow an analysis of interproton NOEs between the spatially proximate aromatic rings. This approach facilitates specific assignments in systems containing multiple aromatic rings in spectra at natural abundance. Evidence is presented for a dynamic process which invokes a correlated conformational change about the C-alpha-C-beta(chi(1)) bond for the pair of interacting Phe residues. NMR results suggest that aromatic ring orientations observed in crystals are maintained in solution. Anomalous temperature dependence of ring current induced proton chemical shifts suggests that solvophobic effects may facilitate aromatic ring clustering in apolar solvents.

The effect of minor addition of Ni on the microstructural evolution and mechanical properties of suction cast Al-0.14 at. pct Sc binary alloy

Aluminum scandium binary alloys represent a promising precipitation-hardening alloy system. However, the hardness of the binary alloys decreases with the rapid coarsening of Al3Sc precipitate during high-temperature aging. In the current study, we report a new approach to compensate for the loss of mechanical properties by combining rapid solidification with very small ternary addition of transition metal Ni. This addition yields dispersion, and at a critical concentration improves the mechanical properties. We explore additions of a maximum of 0.06 at. pct of Nickel to a binary Al-0.14 at. pct Sc alloy, which yield nickel-rich dispersions. We report two kinds of biphasic dispersions containing AlNi2Sc/Al9Ni2 and alpha-Al/Al9Ni2 phase combinations. The maximum improvement in mechanical properties occurs with the addition of 0.045 at. pct Ni with a yield strength of 239 +/- A 7 MPa for an aging treatment at 583 K (310 A degrees C) for 15 hours.

Unprecedented formation of a 14-membered dihydropyran macrocycle via sequential olefin cross metathesis-intramolecular hetero Diels-Alder reaction

Formation of a 2,3-dihydro-4H-pyran containing 14-membered macrocycle by sequential olefin cross metathesis and a highly regiospecific hetero Diels-Alder reaction was observed in the reaction of a hydroxydienone derived from tartaric acid with Grubbs' second generation catalyst. It was found that the free alcohol in the hydroxyenone led to the macrocycle formation, while protection of the hydroxy group formed the ring closing metathesis product. (C) 2013 Elsevier Ltd.
