Pneumonia and pulmonary abscess due to in an immunocompromised patient.

Introduction: are gram-negative bacilli living in soil and aquatic habitats. They are responsible for less than 10% of legionellosis, but have a propensity to affect people suffering from immunodeficiency. Lung cavitations may also occur in this population.

Effects of L-Dopa on circadian rhythms of 6-OHDA striatal lesioned rats: a radiotelemetric study.

Temporal variation in the motor function of Parkinson's disease (PD) patients suggests the potential importance of a chronobiological and chronopharmacological approach in its clinical management. We previously documented the effects of striatal injection of 6-OHDA (as an animal model of PD) on the circadian rhythms of temperature (T), heart rate (HR), and locomotor activity (A). The present work assessed the possible influence of L-Dopa on these same rhythms in the 6-OHDA animal model of PD.

Circadian rhythms of oxidative phosphorylation: effects of rotenone and melatonin on isolated rat brain mitochondria.

Mitochondrial experiments are of increasing interest in different fields of research. Inhibition of mitochondrian activities seems to play a role in Parkinson's disease and in this regard several animal models have used inhibitors of mitochondrial respiration such as rotenone or MPTP. Most of these experiments were done during the daytime.
