Sleep Disorders and Genes

Versão preprintThe sleep-wake cycle is a neurobiological phenomenon that shows intervals of activity alternating with restfulness that appears with a periodicity approximating the 24h day-night cycle. The sleep-wake cycle is under the control of diverse neuroanatomical and neurochemical systems, including monoaminergic, cholinergic, adenosinergic among many other systems. In addition, neuroanatomical centers linked to sleep promotion, such as hypothalamus, project to the cerebral cortex, subcortical relays and brainstem. In addition, the sleep-wake cycle has been associated to aberrant features known as sleep disorders. Here, we will discuss the role of specific gene expression on sleep disturbances. Given the expansion of the knowledge in the sleep-wake cycle area, it is indeed ambitious to describe all the genetics involved in the sleep modulation. However, in this chapter we reviewed the current understanding of the sleep disorders and gene expression.info:eu-repo/semantics/publishedVersio

Diffuse Large B-Cell Lymphoma Mimicking Intramural Hematoma of the Thoracic Aorta

Diffuse large B-cell lymphoma (DLBCL) is an aggressive lymphoma that is fatal if left untreated. Few cases have been reported of involvement of the aorta. Here we present a case of DLBCL that was diagnosed by periaortic computed tomography–guided biopsy. (Level of Difficulty: Intermediate.
