New mechanisms: From lactate to lactylation to rescue heart failure.

Lactylation of α-myosin heavy chain (α-MHC) has recently been reported to preserve sarcomeric structure and function and attenuate the development of heart failure. Specifically, lactylation enhanced the interaction of α-MHC with the sarcomeric protein Titin, thereby maintaining normal sarcomeric structure and myocardial contractile function. Furthermore, the administration of lactate or inhibition of lactate efflux potentially treats heart failure by restoring lactylation of α-MHC and the interaction of α-MHC with Titin.

IgE and TGF-β Signaling: From Immune to Cardiac Remodeling.

Cardiac remodeling is accompanied by cardiac hypertrophy, fibrosis, and dysfunction, eventually leading to heart failure (HF). However, the molecular mechanisms involved in cardiac remodeling are complicated, especially the association with immune. Immunoglobulin E (IgE) is a class of immunoglobulins involved in immune response to specific allergens.

Effects of Jin-Ying-Tang on Staphylococcus aureus-induced mastitis in rabbit.

The present study was performed to investigate the effects of Jin-Ying-Tang (JYT), a Chinese herbal formula containing Lonicera japonica, Herba taraxaci, Fructus trichosanthis, Fructus forsythia, Radix et rhizoma rhei, Astragalus membranaceus, Angelica sinensis, on rabbit mastitis induced by Staphylococcus aureus. Suckling rabbits were challenged with 1.5 × 10(7) colony forming unit (CFU) of S.
