Combination and monotherapy of Leishmania major infection in BALB/c mice using plant extracts and herbicides.

Background & Objectives: Leishmaniasis is a growing health problem in many parts of the world. Efforts to find new chemotherapeutics for leishmaniasis remain a priority. This study was carried out to determine the effect of combination and monotherapies using plant extracts and herbicides on Leishmania major infection in BALB/c mice.

REM sleep and EEG abnormalities in criminal psychopaths.

Hare's (1970) REM deficit theory in psychopathy was investigated. The repeated finding of EEG slowing in waking psychopaths has been interpreted as reflecting cortical immaturity, cortical underarousal, and an intense need for sensory stimulation of psychopaths. REM sleep has been implicated in cortical maturation during development and in daily cortical maintenance.
