Aspectos epidemiológicos e anatomopatológicos do hemagiossarcoma em cães: 40 casos (1965-2012)

Os aspectos epidemiológicos e anatomopatológicos de casos de hemangiossarcoma em cães da Região Central do RS foram estudados. Dos casos avaliados (n=40), cães idosos e da raça Pastor Alemão foram nitidamente os mais afetados (72,2% e 20% dos casos, respectivamente), visto que na população total de cães necropsiados nesse mesmo período (n=7.063) essa faixa etária e raça tiveram comparativamente uma prevalência bem mais baixa (14,6% e 10,1% dos casos, respectivamente). Na necropsia (n=40), os tumores ocorreram quase sempre como nódulos (92,5%) e, menos frequentemente, como massas (37,5%), e afetaram principalmente: baço (62,5%), pulmão (60%), fígado (52,5%), peritônio (42,5%), rim (37,5%), encéfalo (30%), pleura (25%) e coração (22,5%). Hemoperitônio (42,5%) e, consequentemente, anemia (22,5%) foram vistos com certa frequência. Na histologia (n=25), os hemangiossarcomas eram principalmente bem diferenciados (84%), de baixo grau (64%) e com estroma escasso (84%), mas frequentemente (68%) havia áreas com células demonstrando algum grau de atipia. Necrose, hemorragia e trombose foram vistos em todos os casos, mas hematopoiese extramedular (28%) e proliferação angiomatosa benigna (12%) foram achados menos comuns. Na imuno- -histoquímica (n=24), utilizando anticorpo anti-fator de von Willebrand, todos os casos demonstraram marcação de intensidade variável com um padrão citoplasmático finamente granular. Em relação à classificação anatômica, 55% dos hemangiossarcomas foram considerados como multicêntricos, 30% como primários com metástase(s) e 15% como solitários. Esse artigo discute esses resultados e propõe, com base em combinações de órgãos afetados, um esquema de separação entre hemangiossarcomas primário com metástase(s) e multicêntrico, a fim de tentar homogeneizar a maneira com que patologistas veterinários referem-se a esse neoplasma.

Deposición transversal de líquido de las boquillas de doble abanico TTJ60-11004 y TTJ60-11002 en distintas condiciones operacionales

El objetivo de este trabajo fue el de evaluar la deposición transversal de caldo de las boquillas pulverizadoras de doble abanico TTJ60-11004 y TTJ60-11002 en distintas condiciones operacionales. Se utilizaron 5 muestras de cada boquilla pulverizadora siendo considerada cada unidad, una repetición. La distribución de caldo fue evaluada por medio de una mesa de evaluación de distribución construida de acuerdo con la norma ISO 56821. Se evaluó el perfil de distribución individual, la distribución volumétrica simulada de la superposición de los chorros por medio del coeficiente de variación (CV%) de los volúmenes colectados, el caudal y el ángulo de abertura de los chorros. Las condiciones operacionales fueron: presión de trabajo de 200, 300 y 400 Kpa, altura de 30, 40 y 50 cm en relación al blanco y espaciamiento entre boquillas simulados en Software (Microsoft Excel) entre 45 y 100 cm. Las boquillas presentaron perfil individual descontinuo con la mayor deposición de líquido en la región central y reducción del volumen gradual en dirección a las extremidades. El aumento de la presión promovió alargamiento del perfil y de la franja de aplicación. Las boquillas proporcionaron perfil uniforme que dependió del espaciamiento entre las boquillas, con valores menores con reducción en el espaciamiento y en presiones mayores. El caudal y el ángulo del chorro aumentaron con el incremento en la presión.

Índice de agresividad espacial (IAE) de Chenopodium album en el cultivo de algodón para santiago del estero, Argentina

El Índice de Agresividad Espacial (IAE) es un parámetro bioecológico que indica las características de la distribución de malezas. No existen antecedentes sobre el tema en el cultivo de algodón. El objetivo de este trabajo fue determinar el IAE para Chenopodium album (CHEAL) y relacionarlo con las pérdidas de rendimiento. Se trabajó durante la campaña 2007-2008 en el Campo Experimental de la EEA INTA Santiago del Estero, con el cultivar Guazuncho-INTA. Para el cálculo del IAE, se utilizó un modelo que emplea: altura de planta sobresaliente, su biomasa seca y superficie infestada; número de descendientes, biomasa seca y altura media de los mismos. Dentro del cultivo, en 200 m², fueron marcadas 10 áreas de 1 m². Se realizaron análisis estadísticos paramétricos, ANOVA y Tukey (0,05). Los resultados fueron: a) Algodón: peso de parcela medio: 105.000 g; peso por planta: 597 g; el total de plantas: 79,30; altura media: 0,5951 m; rendimiento medio: 2592 kg ha-1 y, b) CHEAL: peso por parcela: 4920 g; nº de plantas por parcela media: 18,7; altura media: 2,72 m; altura de planta madre de maleza: 3,45 m; 187 plantas hijas, medias con 2,40 m de altura y 58 g de biomasa seca, en la parcela de la planta sobresaliente. El rendimiento de algodón fue de 2.329,50 kg ha-1 en el testigo y las pérdidas medias fueron de 89,76%. El IAE obtenido fue de 3,76 (bajo-intermedio) e indica que, en la distribución, actúan numerosas plantas que se desarrollan en torno a una maleza principal. Con un menor IAE, son mayores las pérdidas producidas en el cultivo de algodón.

Diversity and structure of the tree community of a fragment of tropical secondary forest of the brazilian Atlantic Forest domain 15 and 40 years after logging

Two adjacent tracts of tropical secondary forest, situated in Itambé do Mato Dentro, south-eastern Brazil, which had been regenerating for 15 and 40 years after clearing, were compared with the purpose of detecting differences in species diversity and composition, species guild composition (regeneration, stratification and dispersion), and stand structure. Four and three 1,125 m² plots laid on the 15- and 40-year-old stands, respectively, sampled 2,430 trees with diameter at the base of the stem > 5 cm. The number of species (S = 199) was high for this forest type and significantly higher for the older stand. Tree density was significantly higher in the younger stand, particularly for smaller trees, whereas the two stands did not differ in both basal area and volume per hectare. Trees of shade-tolerant and understory species were significantly more abundant in the older stand. Though sharing a large proportion of species (49%), the two stands differed significantly in the abundance of many species. Live stumps probably contributed to the relatively quick restoration of some forest characteristics, particularly species diversity, basal area and volume.

The Effects of the Breast Cancer Mammography Screening Programme in Women aged 40 to 84 years in Turku, Finland (1987-2009)

The objective of this thesis was to evaluate whether a more extensive mammography screening programme (TurkuMSP) conducted by the city of Turku, had an effect on breast cancer (BC) incidence, survival, or mortality in years 1987 to 2009. Despite the fact that some studies have suggested a 20 percent reduction in BC mortality due to mammography screening, there are findings of harm to subjects, which are claimed to negate the benefits of screening. Thus, the aims of this study are most pertinent. A total of 176 908 screening examinations were performed in 36 000 women aged 40−74 during the years 1987−1997. In all, 685 primary BCs were found in the screened women, either screen-detected (n=531) or during screening intervals (n=154). Survival and BC recurrence rate of women with screen-detected BC was compared to 184 women with clinical BCs detected among individuals who did not take part in the screening. The invitation interval, which may influence the outcome, was studied in the age group 40 to 49 by inviting those born in even calendar years annually for mammography screening and those born in odd years, triennially. In addition, BC incidence and mortality in the total female population of Turku aged 40 to 84 years was compared with the respective figures of Helsinki and the rest of Finland, both during the pre-screening era (1976-1986) and the screening era (1987-2009). The study was designed to compare women by age groups, because women aged 50 to 59 were generally screened in all of Finland, whereas only in Turku women aged 40 to 49 and 60 to 74 were screened in addition. Data regarding cancer recurrence were derived from the Finnish Cancer Registry and data on deaths were collected from Statistics Finland. In survival analyses, screened women with invasive BC had a significantly higher survival rate than the women with clinical BC. The survival benefit started to appear already during the first follow-up years and was evident in all age groups. A marginal survival extension was also seen in screened women when BC had spread to ipsilateral axillary nodes already at diagnosis. Recurrence-free survival rate after BC treatment was significantly more favorable among the screened women compared with women with BC found clinically. The screening invitation interval did not significantly influence BC mortality in the subset of women aged 40 to 49 years. There were no consistent differences in the changes of BC incidence between Turku and the comparison areas during the screening era. In Turku, the BC mortality incidence in women aged 55−69 years was significantly lower during the screening era (from 1987 to 1997) compared with the pre-screening era, whereas no such change was found in the city of Helsinki or Tampere. When comparing the changes in incidence-based BC mortality during years 1987 to 2009 in Turku to those of Helsinki and the rest of Finland, there was a suggestion of more than 20 percent lower mortality in Turku among oldest age group (75-84 years) compared with the reference residential areas, but the differences were not consistently significant. Interpretation of the study results should be made with caution because there were no random control groups, and on the other hand, the number of cases in subgroups was fairly low to yield definite conclusions. Also due to the many statistical analyses, some of the findings may be due to chance. The results are, however, suggestive for a decrease of BC mortality in the elderly age groups due to wide mammography screening. This finding needs confirmation in further studies before recommending an expansion of mammography screening to women up to the age of 74 years

A new brain metalloendopeptidase which degrades the Alzheimer ß-amyloid 1-40 peptide producing soluble fragments without neurotoxic effects

A new metalloendopeptidase was purified to apparent homogeneity from a homogenate of normal human brain using successive steps of chromatography on DEAE-Trisacryl, hydroxylapatite and Sephacryl S-200. The purified enzyme cleaved the Gly33-Leu34 bond of the 25-35 neurotoxic sequence of the Alzheimer ß-amyloid 1-40 peptide producing soluble fragments without neurotoxic effects. This enzyme activity was only inhibited by divalent cation chelators such as EDTA, EGTA and o-phenanthroline (1 mM) and was insensitive to phosphoramidon and captopril (1 µM concentration), specific inhibitors of neutral endopeptidase (EC 3.4.24.11) and angiotensin-converting enzyme (EC 3.4.15.1), respectively. The high affinity of this human brain endopeptidase for ß-amyloid 1-40 peptide (Km = 5 µM) suggests that it may play a physiological role in the degradation of this substance produced by normal cellular metabolism. It may also be hypothesized that the abnormal accumulation of the amyloid ß-protein in Alzheimer's disease may be initiated by a defect or an inactivation of this enzyme.

Kantatien 40 liikenneturvallisuustarkastus

Turun kehätie (kantatie 40) on osa Suomen tärkeintä kansainvälistä yhteyttä E18 ja EU:n tärkeäksi priorisoimaa Pohjolan kolmion liikennejärjestelmää. Kantatiellä on erittäin merkittävä rooli Varsinais-Suomen ja sen lähialueiden tieliikenne-, satama-, lentokenttä- ja rautatieasemayhteytenä. Kantatien parantamiseksi on laadittu lukuisia esi- ja tarvesuunnitelmia ja kantatien parantamista on sivuttu sekä liikennejärjestelmä- että kunnittaisissa liikenneturvallisuussuunnitelmissa. Pitkän tähtäimen toimenpidetarpeet ovat kyllä tiedossa, mutta rahoitus toimenpiteille puuttuu. Tästä johtuen kantatien parantamisen ensimmäisenä vaiheena on nyt laadittu liikenneturvallisuusauditointi, jossa on määritetty ensimmäisen ja toisen kiireellisyysvaiheen pienet, toteuttamiskelpoiset ja kustannustehokkaat parantamistoimenpiteet. Nykytilanteen analyysin, maastokäyntien ja työryhmätyöskentelyn pohjalta kantatielle 40 määritettiin yhteensä 258 parantamistoimenpidettä. Toimenpiteet jaettiin kolmeen kategoriaan: A) Ajoratamaalaukset, B) Liikennemerkkijärjestelyt ja C) Infratoimenpiteet. Raportissa kustakin kategoriasta on esitetty lukuisia toimenpide-esimerkkejä valokuvineen. Toimenpiteet jaettiin lisäksi kahteen kiireellisyysluokkaan ja jokaiselle toimenpiteelle esitettiin vastuutaho ja karkea yksikkökustannusarvio. Kaikkien hankkeiden yhteenlaskettu kustannusarvio on noin miljoona euroa. Erittäin pieniä toimenpiteitä ( = kiireellisyysluokka nro 1) on esitetty yhteensä 162 kpl ja niiden kokonaiskustannusarvio on noin 330 000 euroa. Muita kevyitä toimenpiteitä ( = kiireellisyysluokka nro 2) on esitetty yhteensä 96 kpl ja niiden kokonaiskustannusarvio on noin 670 000 euroa. Tässä selvityksessä esitettyjen pienten toimenpiteiden yhteenlaskettu laskennallinen henkilövahinko-onnettomuuksien vähenemä on 1,887 henkilövahinkoon johtanutta onnettomuutta vuodessa (nykyisin noin 18 heva-onnettomuutta vuodessa). Varsinais-Suomen ELY-keskus pyrkii resurssiensa rajoissa toteuttamaan tulevina vuosina esitettyjä toimenpiteitä. Toimenpiteiden toteutusta tullaan seuraamaan ja ensimmäinen seurantapalaveri järjestetään kahden vuoden kuluttua vuoden 2016 lopussa.
