The moderating effect of place attachment on the relationship between economic status and well-being among the older adults in Japan.

IKIGAI is culturally defined as a subjective evaluation of well-being in Japan and is believed to be an important factor in achieving a better life. This study determined the association between economic status and well-being using IKIGAI and the moderating effect of place attachment on their association among 499 older adults people over 65 years of age in Japan. The result of hierarchical multiple regression analysis revealed that lower economic status significantly decreased well-being.

A novel Nrf2 activator, RS9, attenuates secondary brain injury after intracerebral hemorrhage in sub-acute phase.

The poor prognosis of intracranial hemorrhage (ICH) is attributed to secondary brain injury (SBI), which is caused by oxidative stress. Blood components induce reactive oxygen species (ROS) over-production and cause cytotoxicity. We focused on the antioxidant system and investigated nuclear factor-erythroid 2-related factor 2 (Nrf2), which is a transcription factor that controls several antioxidant enzymes.

In Models of Intracerebral Hemorrhage, Rivaroxaban is Superior to Warfarin to Limit Blood Brain Barrier Disruption and Hematoma Expansion.

Background: Intracerebral hemorrhage (ICH) during oral anticoagulation therapy with an oral vitamin K epoxidase reductase such as warfarin is a life-threatening complication. However, whether direct oral anticoagulants (DOACs) are associated with larger hematoma volume and higher mortality rates remains controversial. We evaluated the hematoma volume and pathophysiology of ICH during anticoagulation with warfarin or rivaroxaban, an orally active direct factor Xa inhibitor.

AICAR reduces the collagen-stimulated secretion of PDGF-AB and release of soluble CD40 ligand from human platelets: Suppression of HSP27 phosphorylation via p44/p42 MAP kinase.

We have previously reported that collagen-induced phosphorylation of heat shock protein (HSP) 27 via p44/p42 mitogen-activated protein (MAP) kinase in human platelets is sufficient to induce the secretion of platelet-derived growth factor (PDGF)-AB and the release of soluble cluster of differentiation 40 ligand (sCD40L). Adenosine monophosphate-activated protein kinase (AMPK), which is known to regulate energy homeostasis, has a crucial role as an energy sensor in various eukaryotic cells. The present study investigated the effects of 5-aminoimidazole-4-carboxamide-1-β-d-ribofuranosyl 5'-monophosphate (AICAR), which is an activator of AMPK, on the collagen-induced activation of human platelets.
