Anaplastic cutaneous lymphoma mimicking an infection.

We present a case of a 17-year-old boy who presented with a skin lesion with extension to the soft tissues of the left thigh. On ultrasound, a homogeneous and hypoechoic expansile formation in the subcutaneous tissue was found, measuring 6.5 × 5 × 3.5 cm, with scarce vascularization. Computed tomography showed a low attenuating neoformation with surrounding edema. An inflammatory disorder was the first diagnosis, but the absence of improvement with antibiotics led us to perform magnetic resonance imaging that showed a high signal lesion on T2-weighted imaging and low intensity signal on T1-weighted imaging and surrounding contrast uptake. Positron emission tomography and computed tomography showed uptake of 18F-fluorodeoxyglucose by the lesion. The final diagnosis was anaplastic cutaneous lymphoma

The Solar Twin Planet Search II. A Jupiter twin around a solar twin

Through our HARPS radial velocity survey for planets around solar twin stars, we have identified a promising Jupiter twin candidate around the star HIP11915. We characterize this Keplerian signal and investigate its potential origins in stellar activity. Our analysis indicates that HIP11915 hosts a Jupiter-mass planet with a 3800-day orbital period and low eccentricity. Although we cannot definitively rule out an activity cycle interpretation, we find that a planet interpretation is more likely based on a joint analysis of RV and activity index data. The challenges of long-period radial velocity signals addressed in this paper are critical for the ongoing discovery of Jupiter-like exoplanets. If planetary in nature, the signal investigated here represents a very close analog to the solar system in terms of both Sun-like host star and Jupiter-like planet.Comment: 8 pages, 5 figures; A&A accepted; typos corrected in this versio

Interaction between Arbuscular Mycorrhizal Fungi and rhizobia on the growth of subclover under Mn toxicity: The role of Extraradical Mycelium.

When Arbuscular Mycorrhizal (AM) colonization started from an intact extraradical mycelium (ERM) its bioprotective effect on subclover was enhanced in comparison with other sources of inoculum. The presence in the soil of an intact ERM, developed previously on mycotrophic plants tolerant to Mn toxicity, resulted in the earlier colonization of subclover, reduced Mn concentration in the roots, improved development and activity of root nodules, and enhanced N acquisition

Managing arbuscular mycorrhizal fungi for bioprotection: Mn toxicity

We investigated whether an intact extraradical mycelium (ERM) is more effective than other forms of propagule from indigenous arbuscular mycorrhizal fungi (AMF) in providing protection against stress to a host plant. The response of wheat (Triticum aestivum L.) to Mn toxicity was studied in a two-phase greenhouse experiment. In Phase 1, four Mn tolerant species from the natural vegetation, ranging from strongly mycotrophic to non- or weakly mycotrophic, were grown to develop different amounts of ERM. Wheat was then planted (Phase 2) with the ERM fragmented by sieving (Disturbed Treatment) or kept intact with no prior soil disturbance (Undisturbed Treatment). The growth of wheat was doubled by earlier and faster mycorrhizal colonization (AC) in the presence of an intact ERM at planting. There was a positive correlation between plant growth and the reduction of Mn and enhancement of P and S uptake into shoots. However, the growth of plants in undisturbed soil was significantly affected by the ERM developer species, which was not explained by differences in AC. Colonization starting from an intact ERM greatly enhanced the potential of AMF for protection against Mn toxicity. However, the degree of protection depended on the plant previously grown to develop the ERM, suggesting that there may be functional diversity within the ERM developed by mycotrophic plants of the natural vegetation

Índice de vulnerabilidade socioeconômica e ecológica dos estabelecimentos agrários - IVA.

O presente estudo teve como objetivo investigar e elaborar instrumentos e procedimentos para a proposição de um índice que reflita as vulnerabilidades socioeconômica e ecológica dos municípios do Semiárido brasileiro (IVA). Este índice, baseado em um sistema de indicadores de sustentabilidade, tem o propósito de colocar em prática o conceito de desenvolvimento sustentável. As preocupações com os problemas e desafios socioeconômicos e ecológicos, relacionados ao uso dos recursos hídricos e a estrita dependência econômica da produção agropecuária de sobrevivência, nesta região, remetem a necessidades e proposições de oportunidades de desenvolvimento local, visando proporcionar melhores condições de vida aos habitantes desta região. O IVA construído, permitiu descobrir em qual dimensão de vida a população rural do semiárido é mais vulnerável, classificando-a em elevada, alta, média e baixa e, assim, focalizar as políticas públicas para melhor suprir essas necessidade

Avaliação do comportamento reprodutivo de caprinos naturalizados como doadores de sêmen.

O objetivo do trabalho foi avaliar o comportamento reprodutivo de caprinos de raças naturalizadas para uso como doadores de sêmen do Banco de Germoplasma de Caprinos e Ovinos naturalizados (BGCON). Trinta machos foram avaliados, sendo 17 da raça Canindé e 13 da raça Moxotó. Os animais foram distribuídos em dois grupos experimentais de acordo com a raça. O comportamento reprodutivo foi estimado com os animais submetidos a avaliação individual, em sala de coleta de sêmen. Os parâmetros avaliados foram a libido, o tempo de reação frente a uma ?manequim? e, em seguida da avaliação da aceitação à vagina artificial. O tempo de reação foi classificado em: rápido (até dois minutos), regular (entre dois e quatro minutos) e lento (acima de cinco minutos). Foi analisada a interação de raça e idade. Os dados foram analisados pelo procedimento do General Linear Models (GLM) e as comparações de médias pelo teste Tukey, a 5% de significância, utilizando o SAS. Os animais da raça Moxotó e Canindé apresentaram reação de 61,54% e 17,65%, respectivamente, e de 36,7% independente de raça. Provavelmente esse fato seja reflexo da melhor adaptação da raça Moxotó às condições de exploração submetida

Radiocarbon and blue optically stimulated luminescence chronologies of the Oitavos consolidated dune (Western Portugal)

The dune of Oitavos, the underlying paleosol, and Helix sp. gastropod shells found within the paleosol were dated using a combination of radiocarbon and blue optically stimulated luminescence (OSL). The organic component of the paleosol produced a significantly older age (~20,000 cal BP) than the OSL age measurement (~15,000 yr), while 14C age measurements on the inorganic component and the gastropods produced ages of ~35,000 yr and ~34,000 yr, respectively. Rare-earth element analyses provide evidence that the gastropods incorporate geological carbonate, making them an unreliable indicator of the age of the paleosol. We propose that the 14C age of the small organic component of the paleosol is also likely to be unreliable due to incorporation of residual material. The OSL age measurement of the upper paleosol (~15,000 yr) is consistent with the age for the base of the dune (~14,500 yr). The younger OSL age for the top of the dune (~12,000 yr) suggests that it was built up by at least 2 sand pulses or that there was a remobilization of material at the top during its evolution, prior to consolidation
