Dissecting the Supramolecular Dispersion of Fullerenes by Proteins/Peptides: Amino Acid Ranking and Driving Forces for Binding to C.

Molecular dynamics simulations were used to quantitatively investigate the interactions between the twenty proteinogenic amino acids and C. The conserved amino acid backbone gave a constant energetic interaction ~5.4 kcal mol, while the contribution to the binding due to the amino acid side chains was found to be up to ~5 kcal mol for tryptophan but lower, to a point where it was slightly destabilizing, for glutamic acid.

Post-Burn Infantile Hemangioma in an Extremely Premature Neonate.

Infantile hemangioma (IH) is the most common vascular tumor in infancy, and its physiopathology is not fully understood. Nevertheless, a hypoxic insult may be an essential element for the formation of an IH. Herein, we describe a case of a 25-week premature newborn who developed an IH after a post-burn scar and its evolution.

Pediatric Acute B-Cell Lymphoblastic Leukemia Developing Following Recent SARS-CoV-2 Infection.

Coronavirus disease-2019 in children has been linked to various clinical presentation, from paucisymptomatic cutaneous eruptions, to multisystemic inflammatory syndrome. We report the case of an 8-year-old boy who presented with persistent fever and pancytopenia, associated to a skin rash. An extensive etiological workup showed a positive serology for severe acute respiratory syndrome coronavirus 2 and Epstein-Barr virus.

Mutations in SREBF1, Encoding Sterol Regulatory Element Binding Transcription Factor 1, Cause Autosomal-Dominant IFAP Syndrome.

IFAP syndrome is a rare genetic disorder characterized by ichthyosis follicularis, atrichia, and photophobia. Previous research found that mutations in MBTPS2, encoding site-2-protease (S2P), underlie X-linked IFAP syndrome. The present report describes the identification via whole-exome sequencing of three heterozygous mutations in SREBF1 in 11 unrelated, ethnically diverse individuals with autosomal-dominant IFAP syndrome.
