Aerobic exercise combined with huwentoxin-I mitigates chronic cerebral ischemia injury.

Ca channel blockers have been shown to protect neurons from ischemia, and aerobic exercise has significant protective effects on a variety of chronic diseases. The present study injected huwentoxin-I (HWTX-I), a spider peptide toxin that blocks Ca channels, into the caudal vein of a chronic cerebral ischemia mouse model, once every 2 days, for a total of 15 injections. During this time, a subgroup of mice was subjected to treadmill exercise for 5 weeks.

Osthole protects sepsis-induced acute kidney injury via down-regulating NF-κB signal pathway.

Background And Purpose: As a natural coumarin derivative from the Cnidium monnieri(L)Cusson fruit, osthole consists of 7-methoxy-8-isopentenoxy-coumarin. The purpose of this research is to study the mechanism and effect of osthole on sepsis-induced acute kidney injury.

Experimental Approach: The protective effect of osthole on mouse macrophage RAW 264.

PPAR-γ and tollip are associated with toll-like receptors in colitis rats.

To elucidate the significance of Toll-like receptors and their negative regulating factors PPAR-γ and Tollip on the pathogenesis of colitis. Colitis model was induced by TNBS in rat. The expression of TLR2, TLR4, NF-κBp65, PPAR-γ and Tollip was examined by immunohistochemistry (IHC) and reverse-transcription polymerase chain reaction (RT-PCR).
