In this study, hybrid bio-nanoporous peptides loaded onto poly(-isopropylacrylamide--butylacrylate) (pNIPAM--BA) coatings were designed and obtained matrix-assisted pulsed laser evaporation (MAPLE) technique. The incorporation of cationic peptides magainin (MG) and melittin (Mel) and their combination was tailored to target synergistic anticancer and antibacterial activities with low toxicity on normal mammalian cells. Atomic force microscopy, scanning electron microscopy, X-ray photoelectron spectroscopy, Fourier transform infrared spectroscopy as well as contact angle and surface energy measurements revealed the successful and functional incorporation of both the peptides within porous polymeric nanolayers as well as surface modifications ( variation in the pore size diameter, surface roughness, and wettability) after Mel, MG or Mel-MG incorporation compared to pNIPAM--BA.

This study explored the immunomodulatory and clinical effects of the receptor-interacting serine/threonine protein kinase 1 inhibitor SAR443122 (eclitasertib) in patients with severe COVID-19.
Methods: In this Phase 1b, double-blinded, placebo-controlled study (NCT04469621) a total of 82 patients were screened, of whom 68 patients were eligible and randomized (2:1) to receive eclitasertib 600 mg (300 mg twice daily) or placebo up to 14 days.
The magnitude and breadth of the neutralizing antibody response against variants of concern following natural infection would provide valuable insights regarding the immune response induced by severe acute respiratory syndrome-related coronavirus (SARS-CoV-2) infection. Herein, 25 patients were followed at 30 ±7 (Visit 1), 90± 15 (Visit 2), and 180 ± 15 (Visit 3) days post symptom onset (PSO). The neutralization titers against both Wuhan-Hu-1 (WT) and Delta variant were analyzed in parallel along with anti-Spike antibodies (anti-S1/S2 immunoglobulin G [IgG]).
