Pirkanmaan kaupan alan ennakointiselvitys

FCG Finnish Consulting Group Oy on laatinut yhteistyössä Foredata Oy:n kanssa Pirkanmaan kaupan alan ennakointiselvityksen toimeksiantona Pirkanmaan ELY-keskukselle. Selvitys jakautuu kahteen osaan, joista ensimmäisessä kartoitetaan Pirkanmaan kaupan alan nykytilaa ja toisessa ennakoidaan kaupan tulevaisuuden näkymiä. Ensimmäisessä osassa on analysoitu Pirkanmaan kaupan alan mahdollisuuksia, muutostrendejä, kehityskulkuja ja kehitystarpeita koko maan tilanteeseen nähden. Toisessa osassa selvitetään kaupan alan työvoima- ja koulutustarpeiden kehitysnäkymiä Pirkanmaalla. Selvityksen aineistona on käytetty kaupan alan asiantuntijoiden haastatteluita, tilastoja ja jälkimmäisessä osassa lisäksi avoimia työpaikkailmoituksia. Kaupan alaa Pirkanmaalla luonnehtii voimakas keskittyminen Tampereen seutukuntaan. Tampereen seutukunnassa sijaitsee 76 % kaikista Pirkanmaan tukku- ja vähittäiskaupan toimipaikoista, 84 % henkilöstöstä ja 88 % liikevaihdosta. Kaupan ala on Pirkanmaalla kasvanut viime vuosina huomattavasti muuta Suomea nopeammin toimipaikkojen ja henkilöstön osalta. Ilmastonmuutoksen hillitseminen ja yhdyskuntarakenteen tiivistäminen ovat tällä hetkellä keskeisiä tavoitteita, jotka vaikuttavat myös kaupan alaan. Kaupan viranomaisohjausta pyritään tiukentamaan mm. hillitsemällä suuryksiköiden rakentamista keskustojen ulkopuolelle ja sen sijaan kehittämällä kaupan saavutettavuutta julkisen ja kevyen liikenteen keinoin. Kaupan ala heijastaa yleisiä yhteiskunnallisia muutoksia. Aukioloaikojen vapauttaminen kuvastaa elämänrytmin muutosta ja kauppakeskukset ovat muuttumassa entistä enemmän ajanviettopaikoiksi, joihin yhdistyy myös julkisia palveluita ja asumista. Väestön ikääntyminen tuo toisaalta helposti saavutettavien lähipalveluiden tarpeen, mutta toisaalta ikääntyneet ovat entistä merkittävämpi ostovoimainen kuluttajaryhmä. Toistaiseksi Pirkanmaalla ei ole yhtä yhteistä kaupan alan klusterin kehittämisorganisaatiota, vaan monta yksittäistä toimijaa. Kaupan alan klusteria vahvistaisi nykyistä huomattavasti vahvempi alueellinen brändi. ICT-alan osaamista voitaisiin myös hyödyntää kaupan kehittämisessä. ja toiseksi erikoiskaupan asemaa voitaisiin kehittää elämystalouden osana. Kauppa on merkittävä elinkeino ja tärkeä työllistäjä Pirkanmaalla. Erikoiskaupan alalla tulevaisuuden haastena on ammattitaitoisen työvoiman saaminen. Vaihtuvuus kaupan alalla on suurta, joten yritykset voisivat lisätä vetovoimaisuuttaan tarjoamalla uralla etenemis- ja kouluttautumismahdollisuuksia. Erikoiskaupan alalle voitaisiin uudelleenkouluttaa henkilöitä, jotka ovat tietyn erityisalan osaajia, mutta jotka eivät ole aiemmin työskennelleet kaupan alalla.

Triplex Doppler da artéria renal e a relação entre a ecobiometria dos rins com distância atlanto-coccígea e altura em Canis familiaris

O objetivo do trabalho foi estabelecer a relação entre a ecobiometria renal com medidas de conformação corporal como a distância atlanto-coccígea (DAC) e a altura (H) de cães adultos saudáveis, obtendo-se parâmetros de normalidade para avaliar o tamanho e volume renal, bem como estabelecer valores de referência para avaliar a perfusão sanguínea dos rins por meio do índice de resistividade (IR) e do índice de pulsatilidade (IP) do ramo principal da artéria renal. No estudo foram utilizados 22 cães adultos sem raça definida, sendo 11 machos e 11 fêmeas. Os animais foram previamente aferidos quanto a DAC e a H. Os exames ultra-sonográficos foram realizados com um aparelho HDI 4000 PHILIPS munido de um transdutor microconvexo multifreqüêncial (5-8 MHz), dispositivos Doppler Colorido e Doppler de Fluxo. Os animais foram posicionados em decúbito lateral direito ou esquerdo, de acordo com o rim a ser avaliado. Os diâmetros longitudinal (DL) e dorsoventral (DDV) dos rins foram mensurados na secção longitudinal e, o diâmetro transversal (DT) foi aferido no plano transversal. O volume (V) foi calculado automaticamente pelo software do ultra-som. Com o uso do Triplex Doppler, o IR e o IP das artérias renais direita e esquerda foram obtidos. Todos os dados foram apresentados em média ± EPM. Análises de regressão linear foram realizadas tendo o DL, DDV, DT e V como variáveis dependentes e a DAC e H como variáveis independentes. Os IR e IP dos rins direito e esquerdo foram comparados pelo teste t de Student. A DAC variou de 54-78cm para machos e 37-71cm para fêmeas e a altura variou entre 34-64 cm para os machos e 24-57cm para as fêmeas. As médias obtidas para DL, DDV, DT e V dos rins esquerdo e direito foram: 5,24±0,27cm, 3,07±0,15cm, 3,07±0,9cm, 28,01±3,4mL e 4,50±0,19cm, 2,88±0,14cm, 2,71±0,15cm, 21,27±2,6mL, respectivamente. As análises de regressão linear entre as medidas lineares e volume renal com a DAC e a H foram significativas para os interceptos e coeficientes de regressão (P<0,01). Houve diferenças estatísticas quando comparado os IR e IP entre os rins direito e esquerdo (P=0,001), sendo que as médias para IR e IP dos rins esquerdo e direito foram 0,62±0,08; 1,34±0,18 e 0,70±0,06; 1,62±0,13; respectivamente. Os dados obtidos no presente trabalho podem auxiliar na avaliação do tamanho, volume e perfusão dos rins de cães adultos.

Prevalence and risk factors for Leptospira spp. in cattle herds in the south central region of Paraná state

The aim of this study was to determine the prevalence of anti-Leptospira spp. antibodies and the risk factors for Leptospira spp. infection in breeding cattle herds in the south central region of Paraná state. It was based on the statistic delineation/serological samples and information regarding the selected farms employed in the study of bovine brucellosis for Paraná state in the context of National Program for Control and Eradication of Brucellosis and Tuberculosis. A total of 1.880 females aged >24 months from 274 non vaccinated herds were studied. Serum samples were tested for antibodies against Leptospira spp. using microscopic agglutination test (MAT) with 22 Leptospira serovars. The epidemiological questionnaire was applied on all the selected farms and aimed to obtain epidemiological data. Hundred eighty one of 274 herds were positive for Leptospira spp./presenting prevalence of positive herds of 66.06% (IC95%=60.12-71,65%). Presence of >43 cattle (OR=3.120; IC=1.418-6.867)/animal purchase (OR=2.010; IC=1.154-3.500)/rent of pastures (OR=2.925; IC=1.060-8.068) and presence of maternity paddock (OR=1.981; IC=1,068-3,676) were identified as risk factors for leptospirosis due to any serovar in the multivariate logistic regression. Risk factors for leptospirosis due to serovar Hardjo were presence of >43 cattle (OR=3.622; IC=1.512-8,677)/animal purchase (OR=3.143; IC=1.557-6.342)/rent of pastures (OR=4.070; IC=1.370-12.087) and presence of horses (OR=2.981; IC=1.321-6.726). These results indicate that Leptospira spp. infection is widespread in the south central region of Paraná state and that factors related to the herd characteristic and management are associated with the infection.

Seleção de espécies de adubos verdes visando à fitorremediação de diclosulam

Espécies de adubos verdes tolerantes ao herbicida diclosulam podem ser utilizadas em rotação de culturas para diminuir o efeito fitotóxico subsequente desse herbicida em plantas sensíveis, como o girassol ou milho. Este estudo teve como objetivo avaliar a tolerância de adubos verdes ao diclosulam e a capacidade dessas plantas em diminuir o efeito fitotóxico do herbicida no bioindicador Helianthus annuus. Foram avaliadas, em casa de vegetação, três doses do herbicida diclosulam (0, 0,035 e 0,070 kg i.a. ha-1) em pré-emergência dos adubos verdes Dolichos lablab, Cajanus cajan, Canavalia ensiformis, Crotalaria juncea, C. breviflora, C. spectabilis, Mucuna deeringiana, M. cinerea, M. aterrima, Lupinus albus, Helianthus annuus, Pennisetum glaucum, Avena strigosa, Raphanus sativus e Calopogonium muconoides. Entre estas espécies, C. cajan, C. ensiformis, M. cinerea e M. aterrima foram selecionadas como as mais tolerantes, sendo avaliadas no campo com o herbicida diclosulam nas doses de 0, 0,035 e 0,070 kg i.a. ha¹, em esquema fatorial 4 x 3 e quatro repetições. A parte aérea dessas plantas foi coletada após 60 dias da emergência, sendo semeado H. annuus como bioindicador do herbicida diclosulam. Os resultados evidenciaram C. cajan como a espécie mais promissora em diminuir o efeito fitotóxico do diclosulam em culturas agrícolas sensíveis.

Joroisselän kuormitusselvitys

Joroisselkä on suurehko matala lahtialue, joka kuuluu Saimaan Haukiveteen. Joroisselän tilan on todettu heikentyneen ja osasuunnitelmia on jo tehty tilanteen korjaamiseksi. Tässä raportissa on selvitetty Joroisselkään tulevaa kuormitusta valuma-alueilta. Kuormitusta selvitettiin sekä Suomen ympäristökeskuksen vedenlaatumallin avulla, että vesinäytteenottojen perusteella. Kuormitusselvitys on ensimmäinen askel vesien hoidon suunnittelussa. Sillä saadaan tärkeää tietoa kuormituksen alueellisista eroista ja vesiensuojelulliset toimenpiteet voidaan kohdentaa alueille, joissa niillä saadaan paras mahdollinen vaikuttavuus. Selvityksen perusteella peltoviljelyn osuus Joroisselän kokonaisfosforikuormituksesta on noin 58 % ja typpikuormituksesta 28 %. Muulta maa-alueelta (metsät, suot, avomaat, kalliomaat, rakennetut alueet) tulevan fosforikuormituksen osuus on 25 % ja typpikuormituksen osuus 53 %. Loput kuormituksesta tulee haja-asutuksesta, pistekuormituksesta ja laskeumasta. Vesinäytteenoton perusteella kaukovaluma-alueista pinta-alaan suhteutettuna suurin kuormitus tulee Valvatuksen alueelta. Yksittäisistä pienistä puroista suurin kuormitus havaittiin tulevan Tyrinpurosta, johon tulee Joroisten kunnan jätevedenpuhdistamon puhdistetut vedet. Joroisselän vesienhoidon tavoitteena on rehevöitymisen pysäyttäminen sekä veden tilan parantaminen ja hyvän tilan turvaaminen myös jatkossa. Joroisten taajamassa sijaitsevalla vesialueella on tärkeä merkitys Joroisten alueen virkistyskäytössä. Joroisten alue kuuluu Vuoksen vesienhoitoalueeseen ja se on lisäksi yksi Etelä-Savon ELY-keskuksen vesienhoidollisista painopistealueista.

Allozyme variation in a natural population of Stryphnodendron adstringens in the Rio Preto State Park, southeastern Brazil

Leaves and fruits from 63 Stryphnodendron adstringens trees were sampled in the Rio Preto State Park to analyze allozyme segregation, tissue specific expression of allozyme loci, and their genetic parameters. The enzyme systems ADH, EST, ACP, PGM, PGI, GDH, G6PDH, GOT, IDH, LAP, MDH, PER and SKDH were assessed by means of starch-gel electrophoresis. The polymorphic systems PGI, IDH, MDH and GOT demonstrated a dimeric quaternary structure, while EST and PER were monomeric. The total expected genetic diversity (H E) for leaves and seeds were 0.325 and 0.244 respectively. The effective number of alleles per locus (A E) was 1.58 in leaves and 1.42 in seeds. The values of H E and A E observed in S. adstringens were comparatively higher than the average values seen in allozyme studies of other woody plants. The values of the fixation indices for the population, considering leaves (f = 0.070) and seeds (f = 0.107), were not significant. The high values of genetic diversity and of effective number of alleles per locus, as well as the non-significant fixation index and the adjustments of the Hardy-Weinberg proportions between generations for the pgi-1, mdh-2 and idh-1 loci, indicated random mating in this population. The enzyme systems EST and PER demonstrated their best resolution in leaf tissues, while the MDH, IDH, PGI and GOT systems demonstrated their best resolution in seed tissues.

Holstein white coat color and performance: phenotypic, genetic and environmental correlations

Correlations of measures of percentages of white coat color, five measures of production and two measures of reproduction were obtained from 4293 first lactation Holsteins from eight Florida dairy farms. Percentages of white coat color were analyzed as recorded and transformed by an extension of Box-Cox procedures. Statistical analyses were by derivative-free restricted maximum likelihood (DFREML) with an animal model. Phenotypic and genetic correlations of white percentage (not transformed) were with milk yield, 0.047 and 0.097; fat yield, 0.002 and 0.004; fat percentage, -0.047 and -0.090; protein yield, 0.024 and 0.048; protein percentage, -0.070 and -0.116; days open, -0.012 and -0.065; and calving interval, -0.007 and -0.029. Changes in magnitude of correlations were very small for all variables except days open. Genetic and phenotypic correlations of transformed values with days open were -0.027 and -0.140. Modest positive correlated responses would be expected for white coat color percentage following direct selection for milk, fat, and protein yields, but selection for fat and protein percentages, days open, or calving interval would lead to small decreases.

Plasma clearance and biodistribution of oxidatively modified 99mTc-ß-VLDL in rabbits

The biodistribution and removal from plasma (measured as fractional clearance rate, FCR, per hour) of native and oxidatively modified 99mtechnetium-labeled ß-very low density lipoprotein (99mTc-ß-VLDL) were investigated in hypercholesterolemic (HC) and control (C) three-month old New Zealand rabbits. The intracellular accumulation of ß-VLDL labeled with 99mTc was studied in vitro in THP-1 cells and monocyte-derived macrophages isolated from rabbits. After intravenous injection into C rabbits, copper-oxidized ß-VLDL (99mTc-ox-ß-VLDL) was cleared from the circulation faster (0.362 ± 0.070/h) than native ß-VLDL (99mTc-nat-ß-VLDL, 0.241 ± 0.070/h). In contrast, the FCR of 99mTc-ox-ß-VLDL in HC rabbits was lower (0.100 ± 0.048/h) than that of 99mTc-nat-ß-VLDL (0.163 ± 0.043/h). The hepatic uptake of radiolabeled lipoproteins was lower in HC rabbits (0.114 ± 0.071% injected dose/g tissue for 99mTc-nat-ß-VLDL and 0.116 ± 0.057% injected dose/g tissue for 99mTc-ox-ß-VLDL) than in C rabbits (0.301 ± 0.113% injected dose/g tissue for 99mTc-nat-ß-VLDL and 0.305 ± 0.149% injected dose/g tissue for 99mTc-ox-ß-VLDL). The uptake of 99mTc-nat-ß-VLDL and 99mTc-ox-ß-VLDL by atherosclerotic aorta lesions isolated from HC rabbits (99mTc-nat-ß-VLDL: 0.033 ± 0.012% injected dose/g tissue and 99mTc-ox-ß-VLDL: 0.039 ± 0.017% injected dose/g tissue) was higher in comparison to that of non-atherosclerotic aortas from C rabbits (99mTc-nat-ß-VLDL: 0.023 ± 0.010% injected dose/g tissue and 99mTc-ox-ß-VLDL: 0.019 ± 0.010% injected dose/g tissue). However, 99mTc-nat-ß-VLDL and 99mTc-ox-ß-VLDL were taken up by atherosclerotic lesions at similar rates. In vitro studies showed that both monocyte-derived macrophages isolated from rabbits and THP-1 macrophages significantly internalized more 99mTc-ox-ß-VLDL than 99mTc-nat-ß-VLDL. These results indicate that in cholesterol-fed rabbits 99mTc-ox-ß-VLDL is slowly cleared from plasma and accumulates in atherosclerotic lesions. However, although the extent of in vitro uptake of 99mTc-ox-ß-VLDL by macrophages was high, the in vivo accumulation of this radiolabeled lipoprotein by atherosclerotic lesions did not differ from that of 99mTc-nat-ß-VLDL.

Erythropoietin reduces the expression of myostatin in mdx dystrophic mice

Erythropoietin (EPO) has been well characterized as a renal glycoprotein hormone regulating red blood cell production by inhibiting apoptosis of erythrocyte progenitors in hematopoietic tissues. EPO exerts regulatory effects in cardiac and skeletal muscles. Duchenne muscular dystrophy is a lethal degenerative disorder of skeletal and cardiac muscle. In this study, we tested the possible therapeutic beneficial effect of recombinant EPO (rhEPO) in dystrophic muscles in mdx mice. Total strength was measured using a force transducer coupled to a computer. Gene expression for myostatin, transforming growth factor-β1 (TGF-β1), and tumor necrosis factor-α (TNF-α) was determined by quantitative real time polymerase chain reaction. Myostatin expression was significantly decreased in quadriceps from mdx mice treated with rhEPO (rhEPO=0.60±0.11, control=1.07±0.11). On the other hand, rhEPO had no significant effect on the expression of TGF-β1 (rhEPO=0.95±0.14, control=1.05±0.16) and TNF-α (rhEPO=0.73±0.20, control=1.01±0.09). These results may help to clarify some of the direct actions of EPO on skeletal muscle.

Are serum cystatin C levels influenced by steroid doses in lupus nephritis patients?

INTRODUCTION: Cystatin C is considered a promising test to evaluate glomerular filtration rate, since it has characteristics of an ideal endogenous marker, being similar or even superior to serum creatinine according to some studies. However, it is possible that some factors (as corticotherapy) could have an influence on serum cystatin C levels regardless of the glomerular filtration rate. The aim of this study was to investigate if different doses of glucocorticoid could have an influence on serum cystatin C levels in lupus nephritis patients. METHODS: We evaluated 42 patients with lupus nephritis that performed 109 different blood collections; their mean age was 37.7 ± 13.1 years old, and 88% were female; the mean estimated glomerular filtration rate was of 61.9 ± 20.0 mL/min. Patients were divided according to their glucocorticoid dose in two groups: A - high (pulse therapy with methylprednisolone and prednisone > 0.5 mg/kg/d, n = 14) versus B - low doses (prednisone ≤ 0.5 mg/kg/d, n = 28). Serum creatinine levels were used as parameters for renal function comparison. Cystatin C was determined by an in-house methodology, using Luminex system flow citometry. RESULTS: Considering these groups, cystatin C levels were different only in the second visit (p = 0.106). But, when the serum creatinine levels were considered in the same groups, a marginally significant difference among them (p = 0.070) was observed, which suggested that the difference in cystatin C levels between the groups was caused by their respective glomerular filtration rate. There was not any difference between those groups that received or did not receive pulse therapy. CONCLUSION: Although some previous studies have shown that glucocorticoid has an influence on serum cystatin C levels, we have not observed such interference in the lupus nephritis patients submitted to corticotherapy.

Marcadores moleculares microssatélites na avaliação de sementes de soja com variação na coloração do hilo

Marcadores microssatélite têm sido utilizados na determinação da pureza genética em programas de melhoramento e de produção de sementes, visando garantir a qualidade genética das sementes. Objetivou-se neste trabalho demonstrar, com auxílio de marcadores moleculares microssatélites, que variações na coloração do hilo em sementes de soja, muitas vezes não constituem variação genética. Foram avaliadas sementes de soja da cultivar CD 222 que apresenta sementes com hilo preto, e de duas linhagens (CD 02RV-8444 e CD 01RV-7618), as quais apresentam sementes com hilo marrom. As sementes com variações na coloração e tonalidade do hilo encontradas em cada genótipo foram separadas visualmente em grupos. O DNA de cada semente foi extraído e analisado com marcadores microssatélites em "bulks" contendo DNA de cinco sementes. As variações encontradas na coloração do hilo da cultivar CD 222 e da linhagem CD 02RV-8444 não foram devidas à variação genética, considerando 16 locos microssatélites. Para a linhagem CD 01RV-7618, os bulks de sementes com hilo marrom pigmentado de preto (B1), com hilo marrom mais intenso (B2) e intermediário (B3), foram considerados iguais. Para esta mesma linhagem foi detectada diferença no bulk de sementes com hilo marrom menos intenso (B4), com o primer Satt 070. Duas sementes deste bulk apresentaram o mesmo padrão molecular observado para os outros bulks, no mesmo loco. As demais sementes foram consideradas misturas. A utilização de marcadores microssatélites demonstra que variações na cor ou tonalidade do hilo da soja nem sempre correspondem à variação genética.
