Association of Hemoglobin Decrement During Hospitalization with Prognosis of Aneurysmal Subarachnoid Hemorrhage and Mediation Effects of Cerebral Infarction and Pneumonia.

Background: Hemoglobin decrement is a common complication after aneurysmal subarachnoid hemorrhage (aSAH) and is associated with poor outcome. However, the mediating variables on the causal pathway between hemoglobin decrement and poor outcome in aSAH are not clear.

Methods: This is a single-center retrospective observational study containing all consecutive patients with aSAH admitted to our hospital between January 1, 2019, and June 30, 2022.

Expression of ASIC3 in the Trigeminal Nucleus Caudalis Plays a Role in a Rat Model of Recurrent Migraine.

Acid-sensing ion channel 3 (ASIC3) is abundant in the trigeminal nervous system and is most sensitive to a slight pH decrease. Recent studies have indicated that ASIC3 in the peripheral trigeminal ganglia is likely involved in the pathogenesis of migraine pain. However, it is unclear whether this receptor plays a role in recurrent migraine, namely, migraine chronicity.

Protein Kinase C γ Contributes to Central Sensitization in a Rat Model of Chronic Migraine.

Protein kinase C γ (PKCγ) is a critical regulator of central sensitization and is widely recognized to be involved in the pathogenesis of chronic migraine (CM). However, the function of PKCγ in CM remains unknown. This study investigated the role of PKCγ on pathogenesis of CM.

Neuroprotective effects of tetrandrine against vascular dementia.

Tetrandrine is one of the major active ingredients in Menispermaceae Stephania tetrandra S. Moore, and has specific therapeutic effects in ischemic cerebrovascular disease. Its use in vascular dementia has not been studied fully.

PTEN inhibition preserves trigeminal nucleus caudalis neuron activation through tyrosine phosphorylation of the NR2B subunit at Tyr1472 of the NMDA receptor in a rat model of recurrent migraine.

Objective: Activation of the trigeminal nucleus caudalis is believed to be involved in the pathomechanism of migraine. Evidence suggests that N-methyl-d-aspartate receptor subtype 2B tyrosine phosphorylation, originating from the trigeminal nucleus caudalis neuron dysfunction, might be a triggering mechanism for recurrent migraine. Phosphatase and tensin homolog is thought to have a neuroprotective effect in various neurologic diseases by regulating N-methyl-d-aspartate receptor subtype 2B or tyrosine phosphorylation.

Selection and characterisation of Staphylococcus aureus mutants with reduced susceptibility to the investigational oxazolidinone MRX-I.

MRX-I is a new oxazolidinone antimicrobial under development. In this study, the potential for development of resistance to MRX-I in Staphylococcus aureus was investigated and key mutations were characterised. Determination of spontaneous resistance frequency and the mutant selection window (MSW) were performed with meticillin-susceptible S.
