Elevated serum and cerebrospinal fluid levels of Interleukin-4 related to poor outcome of Aneurysmal subarachnoid hemorrhage.

Aneurysmal subarachnoid hemorrhage (aSAH) is a hemorrhagic cerebrovascular disease that seriously jeopardizes human life and health. Some studies have shown that although Interleukin-4 (IL-4) acts as an anti-inflammatory factor, IL-4 levels are elevated when the disease occurs. This study focuses on exploring the relationship between IL and 4 concentrations in the serum and cerebrospinal fluid (CSF) and poor outcome in patients with aSAH.

Laser Speckle Flowmetry for the Prognostic Estimation Study of Permanent Focal Ischemia in Mice.

The distal middle cerebral artery occlusion (dMCAO) model that mainly targets the cortex and causes low mortality is developed for the study of permanent focal ischemia, and it is highly appropriate for the study in the aged population. The two most common methods used to establish dMCAO models are dMCAO alone and dMCAO plus ipsilateral common carotid artery occlusion (CCAO). Up to now, studies on the prognosis of the two types of dMCAO models and the accuracy of cerebral blood flow (CBF) in predicting prognosis have not yet been reported.

Effects of nFeO capping on phosphorus release from sediments in a eutrophic lake.

This study applied the techniques of high-resolution dialysis (HR-Peeper) and diffusive gradients in thin films (DGT) to explore the effects and the behind mechanism for inhibition phosphorus (P) releasing from sediments by nFeO capping. The highest decreasing rates of SRP and labile P (i.e.

Caudatin induces caspase-dependent apoptosis in human glioma cells with involvement of mitochondrial dysfunction and reactive oxygen species generation.

Caudatin as one species of C-21 steroidal from Cynanchum bungei decne displays potential anticancer activity. However, the underlying mechanisms remain elusive. In the present study, the growth suppressive effect and mechanism of caudatin on human glioma U251 and U87 cells were evaluated in vitro.

Alleviation of brain edema by L-arginine following experimental subarachnoid hemorrhage in a rat model.

Decreased levels of nitric oxide play a role in the development of cerebral ischemia secondary to subarachnoid hemorrhage (SAH). The protective effect of L-arginine on brain edema following SAH was investigated in this study. Rats were divided randomly into a sham-operated, a SAH+saline group and a SAH+L-arginine group.
