Sedative Choice: The Chilling Confounder to Targeted Temperature Management.

Targeted temperature management (TTM) is a technique used in adults who lack a meaningful response after the return of spontaneous circulation following cardiac arrest (CA). The implementation of TTM is believed to improve neurological outcomes by decreasing cerebral metabolism, reducing apoptosis, and lowering oxygen demand. While this technique is recommended as a part of advanced cardiovascular life support (ACLS), there is a lack of consistency regarding drug choice and depth of sedation in TTM.

Genomic deletion of TLR2 induces aggravated white matter damage and deteriorated neurobehavioral functions in mouse models of Alzheimer's disease.

Toll-like receptor-2 (TLR2), a member of the TLR family, plays an important role in the initiation and regulation of immune/inflammation response, which is a critical mechanism underlying Alzheimer's disease (AD). To clarify the role of TLR2 in the pathological process of AD, in the present study, TLR2 knockout plus APPswe/PSEN1dE9 transgenic mice (AD-TLR2KO) were generated. Neurobehavioral tests and brain MRI scan were conducted on mice at the age of 12 months.

Gender difference in the effect of progesterone on neonatal hypoxic/ischemic brain injury in mouse.

This study investigated the effects of progesterone (PROG) on neonatal hypoxic/ischemic (NHI) brain injury, the differences in effects between genders, and the underlying mechanisms. NHI brain injury was established in both male and female neonatal mice induced by occlusion of the left common carotid artery followed by hypoxia. The mice were treated with PROG or vehicle.

5-hydroxymethylcytosine is detected in RNA from mouse brain tissues.

5-hydroxymethylcytosine (5hmC) is considered as a novel DNA modification and plays an important role in cancer, stem cells, and developmental diseases. In this study, we demonstrated the existence of RNA 5hmC modification in mouse brain RNA by using a dot blot analysis method. Our data indicated that 5hmC modification in RNA samples was less than that in DNA samples.

Combined use of spatial restraint stress and middle cerebral artery occlusion is a novel model of post-stroke depression in mice.

Post stroke depression (PSD) is one of the most common complications of ischemic stroke. At present, the underlying mechanisms are unclear, largely because there are no reliable, valid and reproducible animal models of PSD. Here we report a novel animal model of PSD that displays consistent and reliable clinical features of hemiplegic stroke.

TAK-242, an antagonist for Toll-like receptor 4, protects against acute cerebral ischemia/reperfusion injury in mice.

Toll-like receptor 4 (TLR4) contributes to cerebral ischemia/reperfusion (I/R) injury and is a potential target for the treatment of ischemic stroke. This experiment is to evaluate the effect of an exogenous TLR4 antagonist, TAK-242, against acute cerebral I/R injury. A mouse model of cerebral I/R was induced by transient middle cerebral artery occlusion.
