A Cross-Sectional Study of the Physical and Mental Well-Being of Long COVID Patients in Aruba.

To investigate the pattern and prevalence of persistent symptoms of Post-COVID-19 Syndrome (PCS) at 3, 6, 9, and 18 months after discharge. Associated risk factors were further examined to potentially explain the persistence of these symptoms. A cross-sectional cohort study was conducted at the primary health care facility of Aruba, Dr.

Dynamical characterization of two differentially disease associated MHC class I proteins in complex with viral and self-peptides.

Major histocompatibility complex (MHC) class I proteins are expressed on the cell surface where they present foreign and self-peptides to effector cells of the immune system. While an understanding of the structural prerequisites for antigen presentation has already been achieved, insight into subtype- or peptide-dependent dynamical characteristics of a peptide-MHC antigen is so far largely obscure. We approached this problem by employing 400-ns molecular dynamics simulations with two human MHC class I subtypes as model systems: the ankylosing spondylitis-associated HLA-B∗27:05 and the non-ankylosing spondylitis-associated HLA-B∗27:09.
