Lupus-associated hypoprothrombinemia syndrome in children: Differences between post-infectious and autoimmune forms.

Introduction: Lupus-anticoagulant hypoprothrombinemia syndrome (LAHS) is a rare but potentially serious condition. LAHS can be of post-infectious (PI) or autoimmune (AI) origin. However, there is currently no clear data available on the differences between these two forms.

Prefrontal cortex molecular clock modulates development of depression-like phenotype and rapid antidepressant response in mice.

Depression is associated with dysregulated circadian rhythms, but the role of intrinsic clocks in mood-controlling brain regions remains poorly understood. We found increased circadian negative loop and decreased positive clock regulators expression in the medial prefrontal cortex (mPFC) of a mouse model of depression, and a subsequent clock countermodulation by the rapid antidepressant ketamine. Selective Bmal1KO in CaMK2a excitatory neurons revealed that the functional mPFC clock is an essential factor for the development of a depression-like phenotype and ketamine effects.
