Parkinson's disease (PD) is a neurodegenerative disorder characterized by motor symptoms and neuropathological features, such as loss of dopaminergic neurons in the substantia nigra pars compacta and accumulation of alpha-synuclein (α-Syn). Progranulin (PGRN) is a secreted growth factor that exhibits anti-inflammatory properties and regulates lysosomal function. Although autophagy-lysosome pathway is the main degradative pathway for α-Syn, the molecular mechanistic relationship between PD and PGRN remains unclear.

Clinically, an upregulation of VGF levels has been reported in the cerebrospinal fluid and prefrontal cortex of patients with schizophrenia. In our previous study, mice overexpressing VGF exhibited schizophrenia-related behaviors.

We evaluated the correlation between CBF using Laser Speckle Flow Imaging (LSFI) after SAH and neurological findings in the sub-acute phase.
Method: An SAH was induced by endovascular perforation in male mice.
The Asian traditional medicinal plant Acorus calamus and its component α-asarone exhibited various biological activities, such as antiinflammation and antioxidant effects. In the present study, we investigated the in vitro effects of A. calamus extract and α-asarone on oxidative stress- and endoplasmic reticulum (ER) stress-induced cell death in hippocampal HT22 cells.

There have been numerous reports about the antitumour effects of astaxanthin against several tumours but no studies into its effects against glioblastoma. Astaxanthin is a red pigment found in crustaceans and fish and is also synthesized in ; adonixanthin is an intermediate product of astaxanthin.

Purpose: Intracranial hemorrhage (ICH) is a devastating disease with high mortality and morbidity. After ICH, iron released from the hematoma plays a crucial role in secondary brain injury. Deferasirox (DFR) is a trivalent iron chelator, which was approved to treat iron overload syndrome after transfusion.
