Two different molecular mechanisms underly.ng progesterone neuroprotection against ischemic brain damage

Herein, we show that a single injection of P4(4 mg/kg) at 1 h or 48 h, but not 96 h, before middle cerebral artery.occlusion (MCAO) produces significant protective effects against the ischemia-induced neuronal death and the deficits in spatial cognition and UP induction. The present study.focused on the molecular mechanisms underly.ng the neuroprotection exerted by.P4 administration at I h and 48 h pre-MCAO, termed acute and delay.d P4-neuroprotection, respectively. Pharmacology.suggested that P4-receptor(P4R) cascading to a Src-ERK1/2 signaling mediated the delay.d P4-neuroprotection. To support this, it was observed by.anti-phosph-ERK1/2 immunoblots that a single injection of P4 triggered a P4R-mediated persistent increase in ERK1/2 phosphory.ation and their nuclear translocation for 48 h. In contrast, the acute P4-neuroprotection did not depend on the P4R-mediated Src-ERK1/2 signaling. Instead, the acute P4-administration attenuated the NMDA-induced rise in the intracellular calcium concentration([Ca2+] (i) ) that may.be a primary.cause for MCAO-induced neuronal injury. This effect seemed to be exerted by.an antagonism of sigma(1) receptor since the sigma(1) receptor antagonist NE100 perfectly.mimicked the acute P4-neuroprotection and also attenuated the NM- DA-incluced [Ca2+] (i), increase. These findings suggest that the P4 neuroprotection involves two independent processes depending on the timing of P4 administration before MCAO: an acute protection by.antagonizing sigma (1) receptor to inhibit NMDAr-Ca2+ influx and a delay.d one by.an activation of P4R-mediated SrcERK signaling pathway.

To date, there has been no report on fast-charging and Ahlevel sodium-ion batteries (SIBs) by.utilizing thick hard carbon anodes that demonstrate prolonged cy.ling life and high areal capacity.at high rates. Further, the relationship among the complex structure of hard carbon, storage mechanism, and fastcharging performance in alkali-metal ion batteries has been a subject of ongoing debate [1,2].
