Sleep alterations have been described in several neurodegenerative diseases yet are currently poorly characterized in amyotrophic lateral sclerosis (ALS). This study investigates sleep macroarchitecture and related hypothalamic signaling disruptions in ALS. Using polysomnography, we found that both patients with ALS as well as asymptomatic and mutation carriers exhibited increased wakefulness and reduced non-rapid eye movement sleep.

Postpartum depression (PPD) adversely affects the growth and development of the offspring, increasing the risk of various internalizing behaviorsduring adolescence. Studies have shown that corticosterone (CORT)-induced PPD affects neurogenesis in the offspring, which is closely related to the onset of depression. However, the underlying mechanisms of these changes in the offspring of PPD mothers remain unexplored.

Objective: The aim of this study was to characterize the parameters of reproductive anatomy and pituitary hormone expression levels in ames dwarf mice ).
Materials And Methods: Male mice aged 30 days received daily intraperitoneal injections of recombinant human GH and levothyroxine three times weekly for 60 days. The sexual maturation of these animals was compared with that of their wild-type ( ) and untreated ( ) siblings.

The aim of this study is to describe the management and evolution of a patient with the rare condition of double lactotroph tumors and assess the role of intraoperative ultrasonography (IOUS) for their detection and methylation-based liquid biopsy for their diagnosis and monitoring. A 29-year-old woman diagnosed with double lactotroph tumors through hormonal and MRI workup underwent surgical resection due to cabergoline intolerance. To detect a tumor missing through visual inspection, IOUS was performed.
