Distribution and conservation of Oncilla (Leopardus tigrinus) of Yungas, Argentina

En la Argentina y las Yungas, el Tirica es el felino con rango de distribución más restringido y probablemente localmente raro. En este trabajo se presenta un mapa de prioridades de conservación para el Tirica (Leopardus tigrinus) que se desarrolló en base a un mapa de distribución potencial y un mapa de uso de la tierra. Para al mapa de distribución se desarrolló un modelo de distribución de la especie usando el programa MaxEnt y 64 puntos de presencia actual de la Argentina (Yungas y Bosque Atlántico). Se midió el rendimiento general del mapa con el AUC o área bajo la curva ROC, que fue de 0.996; lo que indica un buen rendimiento. Se superpuso este mapa con un mapa de uso de la tierra humano para excluir áreas no aptas para la especie. El mapa resultante indica que ya se ha perdido casi la mitad (48%) del hábitat potencial para la especie, en particular en el borde oriental de su distribución y en el sur donde probablemente la especie nunca estuvo presente. Dos aras son importantes para la conectividad del hábitat y por la alta probabilidad de presencia y por lo tanto, para la conservación de Tirica. Se espera que este mapa sea de utilidad para conservacionistas y tomadores de decisiones.In Argentina and Yungas, Oncilla is the felid species with the smallest distribution range and probably locally rare. Based on the potential distribution map and human land use we present a map indicating important areas for Oncilla conservation. Therefore we developed a potential distribution map for Oncilla (Leopardus tigrinus) using MaxEnt and 64 existing presence points of Argentina (Yungas and Atlantic Forest). We measured the general performance of the map using the AUC or area under the Roc curve, which was 0.996, indicating a model with a good general performance. We superimposed this map with a map of human land use to exclude areas not suitable for the species. The resulting map indicates that already almost half (48%) of potential habitat for the species is lost, particularly in the eastern limit of its distribution and in the south, where the species probably was never present. Two areas are important for habitat connectivity or high presence probability and therefore, conservation of Oncilla. This map is hopefully useful for conservation actions and decision makers.Fil: Cuyckens, Griet An Erica. Universidad Nacional de Jujuy. Facultad de Ciencias Agrarias.

SR 2D micro-XRF imaging on entire rat thin sections in view of a pharmacokinetic study of a new bromine containing drug agains tuberculosis

Tuberculosis (TB) is a common and often deadly infectious disease caused by various strains of mycobacteria, usually Mycobacterium tuberculosis in humans. Because of population growth, the absolute number of new cases is still increasing. Multi-drug-resistant tuberculosis (MDR-TB) is defined as resistance to the two most effective first-line TB drugs and is a public health issue in many developing countries, as treatment is longer and requires more expensive drugs. Recently, a new experimental diarylquinoline anti-tuberculosis drug was discovered at Janssen Pharmaceutica, referred to as TMC207 and shown in Fig. 1. Before TMC207 can be made commercially available, one of the necessary investigations is a thorough pharmacokinetic study to investigate its absorption, distribution, metabolism and excretion (ADME)
