A Case of Disseminated Histoplasmosis From California, in the Setting of Secondary Hemophagocytic Lymphohistiocytosis: A Diagnostic Challenge.

is a geographically specific dimorphic fungus that can cause a spectrum of diseases. While most cases are asymptomatic pulmonary infections, in severe cases, particularly in immunocompromised patients, disseminated disease can occur. Histoplasmosis in California is limited to only a few case reports.

Methicillin resistant infective endocarditis presenting as neutrophilic meningoencephalitis.

Infective endocarditis (IE) with is associated with intravenous drug abuse or infected cardiac devices and commonly presents with non-specific constitutional symptoms. A 53-year-old female presented to the hospital with back pain, altered mental status, fever, and tachycardia. Due to patient's lethargy and decline in respiratory effort, she was intubated and lumbar puncture was performed that revealed neutrophil-predominant leukocytosis of the cerebrospinal fluid.

Hormonal Signaling Cascade during an Early-Adult Critical Period Required for Courtship Memory Retention in Drosophila.

Formation and expression of memories are critical for context-dependent decision making. In Drosophila, a courting male rejected by a mated female subsequently courts less avidly when paired with a virgin female, a behavioral modification attributed to "courtship memory." Here we show the critical role of hormonal state for maintenance of courtship memory.
