Bilateral peripheral facial palsy and mastoid infiltration as symptoms of relapsed acute myeloid leukemia

AbstractBackgroundAlthough Bell's palsy (BP) is the most common cause of peripheral facial palsy (PFP), other etiologies merit investigation.Case reportA 60-year-old female patient presented with recurrent bilateral PFP. Although the patient had a history of acute myeloid leukemia (AML), she had initially been diagnosed with BP-related PFP and had been treated accordingly. When the PFP recurred, additional diagnostic tests were performed. The resulting immunohistochemical profile included CD3 positivity in a few reactive T lymphocytes; positivity for myeloperoxidase in atypical cells; and focal positivity for CD34 and proto-oncogene c-kit proteins in neoplastic cells, thus confirming the suspicion of mastoid infiltration caused by relapsed AML.ConclusionIn patients with neoplastic disease, a finding of PFP calls for extensive investigation in order to rule out the involvement of the temporal bone

Relaxations in Ba2BiSbO6 Double Complex Perovskite Ceramics

The electric properties of the complex double perovskite Ba2BiSbO6 have been investigated using impedance spectroscopy in the frequency range from 1 Hz up to 1 MHz and in the temperature range from room temperature up to 560 K. There are two contributions to the electrical properties due to the grain and grain boundary. The oxygen vacancies play an important role in the conductivity and strongly increase the dielectric constant at high temperatures. The analysis of the frequency dependence of the conductivity clearly shows the structural phase transition of this compound near 515 K

LISTA DE VERIFICACIÓN DE LOS METAZOOS PARÁSITOS DE PECES DE PERÚ

Se proporciona una lista de verficación de todos los registros válidos publicados de los metazoos parásitos reportados en peces marinos y de agua dulce de Perú. Esta lista incluye los registros de 612 especies diferentes de metazoos parásitos (incluyendo parásitos no identificados) que pertenecen a los siguientes grupos: Platyhelminthes (430 total), incluyendo Monogenea (175), Cestoda (140), y Trematoda (115); Crustacea (99); Nematoda (49); Acanthocephala (16); Myxozoa (14) y Annelida (2). Estos parásitos fueron reportados de 207 especies de peces de Perú (174 teleósteos, 31 elasmobranquios y 2 especies de hospederos no determinados). Los registros de los parásitos no identificados a nivel de especie (182 de 612), representando el 30% de todas las especies, también fueron incluidos. Entre los parásitos de peces reportados de Perú, 391 fueron marinos, 217 de agua dulce y 4 especies se encontraron en ambos ambientes, para un total de 1015 asociaciones parásito-hospedero. Las especies de peces que albergaron el mayor número de parásitos fueron Merluccius gayi peruanus Ginsburg, 1954 (32), seguido de Paralonchurus peruanus (Steindachner, 1875) (31), Scomber japonicus Houttuyn, 1782 (31), Sciaena deliciosa (Tschudi, 1846) (29) y Stellifer minor (Tschudi, 1846) (28), todos ellos son peces marinos. Los parásitos con el mayor número de registros fueron las larvas del cestodo Adenocephalus pacificus Nybelin, 1931 (19), larvas del nematodo Anisakis sp. (18), larvas de Contracaecum sp. (17) y larvas y adultos de Lacistorhynchus tenuis (16), los cuales fueron recuperados de peces marinos, excepto las larvas de Contracaecum sp., las cuales fueron recuperados de ambos ambientes. La diversidad de parásitos en peces peruanos parece estar sesgado por el hospedero muestreado de acuerdo a los intereses del investigador, sino que también está relacionado con las características biológicas de los parásitos y de los hospederos

Dihaploid Coffea arabica genome sequencing and assembly.

Coffea arabica which accounts for 70% of world coffee production is an allotetraploid with a genome size of approximately 1.3 Gb and is derived from the hybridization of C. canephora (710 Mb) and C. eugenioides (670 Mb). To elucidate the evolutionary history of C. arabica, and generate critical information for breeding programs, a sequencing project is underway to finalize a reference genome using a dihaploid line and a set of Menu Abstract: Dihaploid Coffea arabica Genome Sequencing and Assembly (Plant and Animal Genome XXIII Conference) https://pag.confex.com/pag/xxiii/webprogram/Paper16983.html [25/02/2015 15:00:12] 30 C. arabica accessions

The role of anthropogenic habitats in freshwater mussel conservation

Anthropogenic freshwater habitats may provide undervalued prospects for long-term conservation as part of species conservation planning. This fundamental, but overlooked, issue requires attention considering the pace that humans have been altering natural freshwater ecosystems and the accelerated levels of biodiversity decline in recent decades. We compiled 709 records of freshwater mussels (Bivalvia, Unionida) inhabiting a broad variety of anthropogenic habitat types (from small ponds to large reservoirs and canals) and reviewed their importance as refuges for this faunal group. Most records came from Europe and North America, with a clear dominance of canals and reservoirs. The dataset covered 228 species, including 34 threatened species on the IUCN Red List. We discuss the conservation importance and provide guidance on how these anthropogenic habitats could be managed to provide optimal conservation value to freshwater mussels. This review also shows that some of these habitats may function as ecological traps owing to conflicting management practices or because they act as a sink for some populations. Therefore, anthropogenic habitats should not be seen as a panacea to resolve conservation problems. More information is necessary to better understand the trade-offs between human use and the conservation of freshwater mussels (and other biota) within anthropogenic habitats, given the low number of quantitative studies and the strong biogeographic knowledge bias that persists.This publication is based upon work from COST Action CA18239, supported by COST (European Cooperation in Science and Technology).
