Prevalence and clinical features of long COVID from omicron infection in children and adults.

We read with interest the article reported by Elda Righi et al. about persistent symptoms after COVID-19.1 Following acute infection, various long-lasting symptoms such as fatigue, headache, cough, and muscle pain are described as “long COVID.”2 The World Health Organization (WHO) and the United States Centers for Disease Control and Prevention (CDC) have given incongruous definitions.3, 4 The prevalence of long COVID varies widely, partly because of variability in definitions, study design, sampling frame, vaccine status, comorbidity, and other factors.

Unique Mechanical Properties of Gel-Incorporating Protein Crystals

Crystalline materials that are grown in gel media exhibit reinforced mechanical characteristics. Studies on the mechanical properties of protein crystals are limited in numbers because of the difficulty in growing high-quality large crystals. This study shows the demonstration of the unique macroscopic mechanical properties by compression tests of large protein crystals grown in both solution and agarose gel.
