Effect of heroin in decomposing tissues on the development rate of Boettcherisca peregrina (Diptera, Sarcophagidae) and implications of this effect on estimation of postmortem intervals using arthropod development patterns

Larvae of the flesh fly Boettcherisca peregrina (Robineau-Desvoidy) were reared on the tissues of rabbits to study the effects of heroin on the development rates of this species. The rabbits were given 6, 12, 18, and 24 mg of heroin by cardiac puncture. From Hours 18 to 96, larvae feeding on tissues containing heroin (as morphine) developed more rapidly than those feeding on tissues from the control. The time required for pupation was significantly greater for colonies fed on tissues from heroin-dosed rabbits than for the control colony. The differences observed in the rates of development were sufficient to alter postmortem interval estimates based on larval development by up to 29 h and estimates based on pupal development by 18 to 38 h.     

Mexico, the PRI, and López Obrador: The Legacy of Corporatism

Although differences between the Mexican and U.S. political systems have narrowed of late, a huge gulf continues to separate the two systems. At the heart of this disparity lies the phenomenon of corporatism, a social concept that is virtually absent in U.S. political discourse and traditions. This article considers the intellectual origins of corporatism, why it meshes so well with Ibero-Hispanic society, and how Mexico City's former mayor, Andrés Manuel López Obrador, fashioned his own brand of corporatism to confront the administration of Felipe Calderón Hinojosa, who defeated him in the July 2006 presidential race.
