Factors associated with clinical progression to severe COVID-19 in people with cystic fibrosis: A global observational study.

Background: This international study aimed to characterise the impact of acute SARS-CoV-2 infection in people with cystic fibrosis and investigate factors associated with severe outcomes. Methods Data from 22 countries prior to 13 December 2020 and the introduction of vaccines were included. It was de-identified and included patient demographics, clinical characteristics, treatments, outcomes and sequalae following SARS-CoV-2 infection.

Influence of Echinacea purpurea (L.) Moench extract on the toxicity of cadmium.

Echinacea purpurea (L.) Moench (EP) has many beneficial features, especially strengthening the immune system. Cadmium (Cd) is a ubiquitous metal and cumulative poison that may cause liver and kidney damage and the formation of neoplasia.

Assessment of the effect of Echinacea purpurea (L.) Moench on apoptotic and mitotic activity of liver cells during intoxication by cadmium.

Cadmium (Cd(2+)) is an important industrial pollutant, although its mechanism of toxicity has not been completely clarified. Cd(2+) is toxic to a wide range of organs and tissues, however, the primary target organs of Cd(2+) toxicity are the liver and kidney. Echinacea purpurea stimulating one or another tread of the immune system stimulates the expression of immunoglobulins and interferons.

Effects of cadmium and zinc ions on mitotic activity and protein synthesis in mouse liver.

Objective: To evaluate the in vivo effects of cadmium and zinc ions on mitotic activity and protein synthesis in mouse liver.

Material And Methods: White outbred mice were injected intraperitoneally with cadmium chloride solution (14 micromoles cadmium per 1 kg of body mass) and/or with zinc sulfate solution (48 micromoles zinc per 1 kg of body mass). Histological slides were examined by light microscopy.
