There are studies evaluating the association of serum lactate dehydrogenase (LDH) and albumin levels with mortality in COVID-19 patients. The aim of our study was to evaluate the predictive effect of the LDH/albumin ratio (LAR) on mortality and poor clinical course in COVID-19 patients. A total of 2093 patients for whom LDH and albumin tests were available were included in the study.

Background: Sarcoidosis is a chronic disease of unknown etiology characterised by systemic non-caseating granulomas that can affect any organ in the body, especially the lungs and in which genetic and environmental factors are thought to play a role in its pathophysiology. Adipokines and myokines secreted from adipose and muscle tissue play a role in the pathogenesis or protection against many inflammatory and autoimmune diseases in which inflammation and immunity form the basis. In our study, we aimed to investigate the role of the irisin and adiponectin in sarcoidosis.

Article Synopsis
  • The perception of lightness on a surface is influenced by both the light it reflects and the surrounding context.
  • Despite significant research, the neural mechanisms behind context-dependent lightness perception are still debated.
  • In an fMRI study with 10 participants, it was found that changes in surrounding luminance at low frequencies led to an illusory change in the perceived lightness of a disk, while higher frequencies showed minimal effect, with activity in the primary visual cortex (V1) correlating with these lightness perceptions.
