Abstract Here we provide an analysis of primary results obtained from a study of apoferritin crystal nucleation in compositionally invariant bulk solution at constant supersaturation ratio of the protein. The temperature dependence of the stationary crystal nucleation rate in the protein bulk solution is obtained with the help of experimentally determined probability for detection of at least one crystal per solution volume until a given time. The stationary crystal nucleation...

Abstract The cell nucleus stores the genetic material essential for life, and provides the environment for transcription, maintenance, and replication of the genome. Moreover, the nucleoplasm is filled with subnuclear bodies such as nucleoli that are responsible for other vital functions. Overall, the nucleus presents a highly heterogeneous and dynamic environment with diverse functionality. Here, we propose that its biophysical complexity can be organized around three inter-related...

Abstract Entamoeba histolytica (E. histolytica) is an etiological agent of human amoebic colitis, and it causes a high level of morbidity and mortality worldwide, particularly in developing countries. Ca2+ plays a pivotal role in amoebic pathogenesis, and Ca2+-binding proteins (CaBPs) of E. histolytica appear to be a major determinant in this process. E. histolytica has 27-EF-hand containing CaBPs, suggesting that this organism has complex Ca2+ signaling cascade. E. histolytica...

Abstract We treated two patients with severe respiratory failure due to coronavirus disease 2019 (COVID-19). Case 1 was a 73-year-old woman, and Case 2 was a 65-year-old-man. Neither of them had a history of autoimmune disease. Chest computed tomography scans before the antiviral therapy showed bilateral multiple patchy ground-glass opacities (GGO) consistent with COVID-19 pneumonia. The GGO regressed over the course of the antiviral treatment; however, new non-segmental patchy...

Abstract Introduction Neutrophils act as first responders during an infection, following signals from the pathogen as well as other host cells to migrate from blood vessels to the site of infection. This tightly regulated process is critical for pathogen clearance and, in many cases, eliminates the pathogen without the need for an additional immune response. It is, therefore, critical to understand what signals drive neutrophil migration...
