Redox control in arsenic accumulation with organic matter derived from a varved lacustrine deposit in the Jurassic accretionary complexes.

Oxidation states and distribution of arsenic (As) in annually laminated (varved) lacustrine deposits were analyzed with a seasonal resolution. This deposit was formed in the mid-Holocene landslide-dammed paleolake in the upper reaches of the Ane River, central Japan and the paleolake watershed consists of the Jurassic accretionary complexes (Mino-Tamba belt) including sedimentary and igneous rocks. In the outcrop, centimeter-to-decimeter-scale silty clay layers alternating with laminated layers are well developed.

Pancreatectomy with Celiac Axis Resection and Reconstruction for Locally Advanced Pancreatic Cancer.

Background: With the advent of effective chemotherapy, conversion surgery (CS) has been performed in patients who have responded to pretreatment, even for pancreatic cancer diagnosed as unresectable (UR) at the time of initial diagnosis. In CS, major arterial resection and reconstruction are necessary for complete radical resection.

Methods: We discuss the key points for safely performing pancreatectomy with celiac axis (CA) resection combined with reconstruction, divided into resection and arterial reconstruction.

Bilateral vocal cord paralysis following ventriculoatrial shunt placement for hydrocephalus after subarachnoid hemorrhage: illustrative case.

Background: A ventriculoatrial (VA) shunt is an alternative to a ventriculoperitoneal (VP) shunt for managing hydrocephalus, especially when VP shunt insertion is not feasible. Despite its decline in use, the VA shunt remains vital for certain patients. This report highlights a rare complication of bilateral vocal cord paralysis following VA shunt insertion for hydrocephalus secondary to subarachnoid hemorrhage.

Dysregulation of PI4P in the trans Golgi regions activates the mammalian Golgi stress response.

The Golgi stress response is an important cytoprotective system that enhances Golgi function in response to cellular demand, while cells damaged by prolonged Golgi stress undergo cell death. OSW-1, a natural compound with anticancer activity, potently inhibits OSBP that transports cholesterol and phosphatidylinositol-4-phosphate (PI4P) at contact sites between the endoplasmic reticulum and the Golgi apparatus. Previously, we reported that OSW-1 induces the Golgi stress response, resulting in Golgi stress-induced transcription and cell death.

Proximity to public transportation and incidence of depression risk among older adults: A three-year longitudinal analysis from the Japan Gerontological evaluation study.

Objective: Depression in older adults has been associated with environmental factors, such as green spaces and walkable neighborhoods; however, evidence on the relationship between proximity to public transportation and mental health is scarce. This multi-municipality longitudinal study examined the association between proximity to public transportation and risk of depression among older adults and considered car usage.

Methods: We analyzed data from 4947 functionally independent adults, aged 65 years and older who resided in 25 municipalities across Japan.
