Background: An increase in choroid plexus (CP) volume may be associated with cognitive decline in older individuals without dementia. In this study, we aimed to clarify whether CP volume can serve as an imaging marker of cognitive decline, determine how strongly CP volume is associated with cognitive decline, and explore factors associated with CP volume in older adults.
Methods: We measured CP volume, brain parenchyma, and cerebrospinal fluid (CSF) spaces associated with disproportionately enlarged subarachnoid space hydrocephalus (DESH), an imaging feature of normal-pressure hydrocephalus, in community-dwelling older adults aged ≥ 65 years without dementia.
Evaporation in mixed solutions containing both volatile and involatile solvents changes the properties of the binary solvent. We found that evaporating one solvent drastically increased the affinity of the mixed solvent to dispersant molecules and induced a switch from flocculated to dispersed TiO nanoparticles (TiONPs). We prepared dispersions of TiONPs with mixtures of volatile cyclosiloxane (D), involatile polar oil, and a dispersant, namely polyhydroxystearic acid (PHSA).

Article Synopsis
- A study investigated the link between endometriosis and perinatal complications, specifically focusing on the incidence of placenta previa in women with a history of the condition.* -
- It compared 133 deliveries from mothers with endometriosis to 2,648 without endometriosis, finding that those with endometriosis had a significantly higher risk of placenta previa.* -
- The findings suggested that women with more complete surgical treatment for endometriosis had a lower incidence of placenta previa, indicating that treatment may reduce complications before pregnancy.*
Article Synopsis
- - The study aimed to assess the awareness of sexual reproductive health and rights (SRHR) among members of the Japan Society of Obstetrics and Gynecology (JSOG) and identify how the JSOG can better address SRHR issues.
- - Surveys conducted in 2019 and 2023 showed a significant increase in awareness of SRH and Sustainable Development Goals among JSOG members, with many respondents recognizing various SRHR issues that need attention.
- - The findings highlight a shift in priority issues, with women's rights to self-determination emerging as the most important concern in the second survey, along with calls for comprehensive sexuality education.
We develop and evaluate an artificial intelligence (AI)-based algorithm that uses pre-rotation atherectomy (RA) intravascular ultrasound (IVUS) images to automatically predict regions debulked by RA. A total of 2106 IVUS cross-sections from 60 patients with de novo severely calcified coronary lesions who underwent IVUS-guided RA were consecutively collected. The 2 identical IVUS images of pre- and post-RA were merged, and the orientations of the debulked segments identified in the merged images were marked on the outer circle of each IVUS image.
