Mysidopsis gemina Price, Heard & Vargas, 2019, uma espécie de camarão misidáceo registrada no Pacífico da Costa Rica, foi coletada no oeste do México, em 19 de outubro de 2022, na entrada do Golfo da Califórnia. Este é o primeiro registro ao norte da Costa Rica e representa uma extensão ao norte de cerca de 13 graus de latitude. Apresenta-se uma comparação entre os caracteres morfológicos diagnósticos do material da Costa Rica e do México.Mysidopsis gemina Price, Heard & Vargas, 2019, una especie de camarón misidaceo registrada para el Pacífico de Costa Rica, fue recolectada en el occidente de México, el 19 de octubre de 2022, en la entrada del golfo de California. Este es el primer registro al norte de Costa Rica y representa una extensión del intervalo de distribución hacia el norte de unos 13 grados de latitud. Se proporciona una comparación entre los caracteres morfológicos diagnósticos del material de Costa Rica y de México.Mysidopsis gemina Price, Heard & Vargas, 2019, a species of mysid shrimp recorded for Pacific Costa Rica, was collected in western Mexico on October 19th, 2022, at the entrance of the Gulf of California. This is the first record north of Costa Rica and it represents a distribution range extension to the north of approximately 13 degrees of latitude. A comparison of the diagnostic morphological features of the Costa Rican and Mexican specimens is given

Medical Aspects of mTOR Inhibition in Kidney Transplantation

The advances in transplant immunosuppression have reduced substantially the incidence of kidney graft rejection. In recent years, the focus has moved from preventing rejection to preventing the long-term consequences of long-standing immunosuppression, including nephrotoxicity induced by calcineurin inhibitors (CNI), as well as infectious and neoplastic complications. Since the appearance in the late 1990s of mTOR inhibitors (mTORi), these unmet needs in immunosuppression management could be addressed thanks to their benefits (reduced rate of viral infections and cancer). However, management of side effects can be troublesome and hands-on experience is needed. Here, we review all the available information about them. Thanks to all the basic, translational and clinical research achieved in the last twenty years, we now use mTORi as de novo immunosuppression in association with CNI. Another possibility is represented by the conversion of either CNI or mycophenolate (MPA) to an mTORi later on after transplantation in low-risk kidney transplant recipients. © 2022 by the authors

Mammals of an agricultural landscape of oil palm in the floodplains of the Orocué River, Casanare, Colombia

The llanos region in eastern Colombia exhibits great biodiversity, and is being threatened by agro-industrial processes such as oil palm plantations. However, information about the mammals associated with these landscapes is very limited. We measured richness and capture frequencies of medium and large sized mammals using camera traps in an oil palm plantation and surrounding natural ecosystems, in the seasonally flooded savannas of the Department of Casanare, Colombia. We identify 16 medium to large mammals, and two species of mice, with a survey effort of 3937 camera/days. Capture frequencies varied according to the land cover type. All species were present in the gallery (riparian) forest. Nine species were also detected inside the oil palm plantation and six in savannas. The mammals we found in the plantation were mainly mesopredators and generalist species, while the mammals detected in forest have more restricted diets. We discuss the importance of the gallery forests and artificial lagoons as landscape tools that could enhance diversity in these agro-ecosystems

Mamíferos de un agropaisaje de palma de aceite en las sabanas inundables de Orocué, Casanare, Colombia

Sin embargo, el conocimiento relacionado con la biodiversidad asociada a estos cultivos y su posible repercusión sobre la fauna silvestre nativa es mínimo. Por medio de fototrampeo se determinó la riqueza y frecuencia de captura de los mamíferos medianos y grandes asociados a una plantación de palma de aceite y sus ecosistemas naturales circundantes, en las sabanas inundables del departamento de Casanare, Colombia. Con un esfuerzo de muestreo de 3937 días/cámara se detectaron 16 especies de mamíferos medianos y grandes, y dos especies de ratones, cuyas frecuencias de captura variaron según el tipo de cobertura. Todas las especies estuvieron presentes en el bosque de galería; nueve de ellas estuvieron asociadas a palma y seis a sabana. Los mamíferos encontrados en la plantación fueron principalmente especies de mesodepredadores y generalistas, mientras que los de interior de bosque tienen dietas más restringidas. Se discute la importancia de los bosques de galería y las lagunas artificiales como herramientas de paisaje que mejorarían la diversidad en este tipo de agroecosistemas

47,XXY/48,XXXY/49,XXXXY mosaic with hydrocephaly: a case report and review of the literature

Klinefelter's syndrome is a frequent genetic sexual alteration in males, associated with the 47,XXY aneuploidy. Several syndrome variants are caused by different X and Y polysomy and mosaicisms, including the 49,XXXXY condition described by some authors as Fraccaro's syndrome. Mosaics with three or more different chromosomal lines are very rare. Here, we describe a case with XXY/XXXY/XXXXY mosaic in a newborn with clinical features of Fraccaro's syndrome, but also with obstructive hydrocephaly which has not been reported previously
