Changes in Anti-SARS-CoV-2 IgG Subclasses over Time and in Association with Disease Severity [PDF]

open access: yesViruses, 2022
IgG is the most prominent marker of post-COVID-19 immunity. Not only does this subtype mark the late stages of infection, but it also stays in the body for a timespan of at least 6 months.

Comparative analysis of the growth and development of male and female Pevtsov's toad, Bufotes pewzowi (Amphibia: Anura, Bufonidae) in laboratory conditions

open access: yesCurrent Studies in Herpetology, 2023
Differences in growth rates are shown, as well as in the cost of rearing male and female Bufotes pewzowi under laboratory conditions. We observed a tendency for females to be superior in length and weight, but statistically significant differences (U = 13, p < 0.05) were noted only in weight after 50 weeks of rearing.
