Miliary coccidioidomycosis mimicking tuberculosis: Case report and review of literature.

Miliary coccidioidomycosis is a severe manifestation of diseases caused by and that is endemic to the southwestern United States as well as Central and South America. While most cases of coccidioidomycosis present with pulmonary disease, certain risk factors increase the risk for disseminated disease. We present a case of miliary coccidioidomycosis in a 46-year-old patient with uncontrolled diabetes.

Stress increases sperm respiration and motility in mice and men.

Semen quality and fertility has declined over the last 50 years, corresponding to ever-increasing environmental stressors. However, the cellular mechanisms involved and their impact on sperm functions remain unknown. In a repeated sampling human cohort study, we identify a significant effect of prior perceived stress to increase sperm motility 2-3 months following stress, timing that expands upon our previous studies revealing significant stress-associated changes in sperm RNA important for fertility.

Heterozygosity for neurodevelopmental disorder-associated variants yields distinct deficits in behavior, neuronal development, and synaptic transmission in mice.

Genetic variants in are associated with neurodevelopmental disorders (NDDs) including schizophrenia (SCZ), autism spectrum disorder (ASD) and intellectual disability. TRIO uses its two guanine nucleotide exchange factor (GEF) domains to activate GTPases (GEF1: Rac1 and RhoG; GEF2: RhoA) that control neuronal development and connectivity. It remains unclear how discrete variants differentially impact these neurodevelopmental events.

Severe flea-borne typhus complicated by hemophagocytic lymphohistiocytosis: A case report and review of literature.

Flea-borne typhus (FBT), also known as murine typhus, is a zoonotic infection caused by with world-wide distribution. In the United States, the infection is uncommon but remains endemic in some areas, including Los Angeles County. It typically manifests as a benign acute febrile illness but can be complicated in a minority of cases.
