Calcium- and Integrin-Binding protein 2 (CIB2) is a widely expressed protein with an uncertain biological role. Two of its four EF-hand motifs bind Mg(II) and/or Ca(II), thus triggering conformational changes. Although previous studies suggested that CIB2 preferentially binds Mg(II) over Ca(II) under physiological conditions, an atomic level characterization of CIB2 in the presence of both cations was lacking.

Through a systematic study, the collimation power of the facility was reevaluated. What was initially considered to be values of 230, 420, and 760 have been proven to be much higher.

GC-376, a peptidomimetic 3CL protease inhibitor, has shown significant efficacy against coronaviruses. Recently, a GC-376-based PROTAC was developed to target and induce the proteasome-mediated degradation of the dimeric SARS-CoV-2 3CL protein.

We decided to analyze the population involved in the ReLiFiRa study by identifying two groups of patients: 65 years or more and less than 65 years of age, evaluating the efficacy and tolerability of 200 mg of Filgotinib daily.
Methods: Of the 120 ReLiFiRa patients, 54 were younger than 65 years old and 66 patients were 65 years old or older.
