Annual SZ: An Alternative Immunotherapy for COVID-19 and Long COVID.

Since the outbreak of coronavirus disease 2019 (COVID-19) in late 2019 and early 2020, the identification of drugs to control severe acute respiratory syndrome coro-navirus 2 (SARS-CoV-2) infection and its symptoms has been a pressing focus of research. Cytokine storm and acute respiratory distress syndrome (ARDS) are the leading causes of mortality following infection. In this review, we discuss immune pathogenesis and four medications, including Remdesivir, Tocilizumab, Dexamethasone, and Annual SZ for COVID-19.

Dietary supplementation with 15% tomato pomace (Solanum lycopersicum L.) improves sperm production and antioxidant status in aged male broiler breeders.

The objective was to investigate effects of dietary tomato pomace (TP) and L-Arginine (L-Arg; 10% above nutritional recommendation) in aged male broiler breeders. Thirty male broiler breeders (Ross 308), 58 wk old, were randomly and equally allocated into five experimental groups: basal diet (C); 5% TP-supplemented (T-5); 10% TP-supplemented (T-10); 15% TP-supplemented (T-15); and L-Arg supplemented (L-10) groups. In contrast to the Control and TP-supplemented groups, sperm of L-10 roosters had higher C14:1, C16:0 and C18:1 n-9c proportions, total saturated fatty acid (FA) contents, and n-6:n-3 ratios, but a lower C22:4 n-6 content (P<0.
