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.

A sellar spine is a rare midline osseous spur, which arises from the dorsum sellae and projects into the pituitary fossa. It can be found incidentally on imaging or may present with symptoms related to optic chiasm compression or hormonal disturbances.Herein, we present the case of an incidentally detected sellar spine in a patient presenting with sudden onset headaches.

Laboratory of Gene Engineering and Genomics, School of Basic Medical Sciences, Chengde Medical University, Chengde, 067000, China.
Objective: This study aims to elucidate the primary signaling communication among papillary craniopharyngioma (PCP) tumor cells.
Methods: Five samples of PCP were utilized for single-cell RNA sequencing. The most relevant ligand and receptor interactions among different cells were calculated using the CellChat package in R software.
Single-cell transcriptomics identify a novel macrophage population associated with bone invasion in pituitary neuroendocrine tumors.

Background: Bone-invasive Pituitary Neuroendocrine Tumors (BI PitNETs) epitomize an aggressive subtype of pituitary tumors characterized by bone invasion, culminating in extensive skull base bone destruction and fragmentation. This infiltration poses a significant surgical risk due to potential damage to vital nerves and arteries. However, the mechanisms underlying bone invasion caused by PitNETs remain elusive, and effective interventions for PitNET-induced bone invasion are lacking in clinical practice.
