Psoriasis And Its Interplay With Liver Diseases: Evidence, Mechanisms, And Clinical Implications, Rajaa Jaber Abdel Rasul, Noor Abdulhussain Naama, Sabaa Abd Jaber, Noor Faraj Kadhem

Muthanna Medical Journal

Psoriasis is a chronic inflammatory disease of immune-related origin. It is no longer classified solely as a localized skin disorder but is now recognized as a systemic disease associated with numerous complications and co-morbidities. Recent studies have demonstrated a strong link between psoriasis and several liver diseases, particularly non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatohepatitis (NASH), and cirrhosis. This association is attributed to shared pathogenic mechanisms among these diseases, including metabolic disturbances, oxidative stress, and chronic inflammation, as well as the pivotal role of inflammatory cytokines such as tumor necrosis factor-alpha (TNF-α ), interleukin-6 (IL-6), and interleukin-17 (IL-17).

Drifting Neurons, Stable Geometry: Population Representations Of Instrumental Behavior In The Dorsomedial Striatum, Arati Sharma

Dartmouth College Ph.D Dissertations

The brain reliably supports learned behaviors over long periods of time despite continual biological changes that alter the activity of individual neurons, and the connections between them. For learned behaviors to persist, the information stored in neural populations must remain accessible even when the activity of individual neurons changes. Understanding how the brain achieves this is a fundamental challenge in neuroscience. The dorsomedial striatum (DMS) is critical for instrumental behavior, encoding information about actions, outcomes, and their relationships. Although extensive work has characterized the role of the DMS during learning and performance, less is known about how task-related information is …
