Flooding causes severe yield losses worldwide, making it urgent to enhance crop tolerance to this stress. Since natural flooding often involves physical flow, we hypothesized that the effects of submergence on plants could change when combined with physical flow. In this study, we analyzed the growth and transcriptome of exposed to submergence or flooding with physical flow.

Article Synopsis
  • - The study investigates how aging affects the peribiliary gland's (PBG) response to ischemia-reperfusion injury (IRI) in liver tissue from young and old rats.
  • - Results indicate that old rats experienced significant increases in PBG volume and cell proliferation, as well as more mucus production and oxidative stress compared to young rats following IRI.
  • - Findings suggest that differences in the PBG's response to injury based on age may contribute to the frequency of ischemia-type biliary lesions (ITBLs) in aged donor grafts.

Purpose: We determined the usefulness of the estimation of physiologic ability and surgical stress (E-PASS), initially reported as a predictive factor for postoperative morbidity and mortality, as a prognostic indicator in stage II colorectal cancer (CRC).

Methods: Overall, 739 patients who underwent proctocolectomy for CRC at Tottori University Hospital and affiliated hospitals and histologically diagnosed with stage II CRC were included in the current study.

Results: A receiver operating characteristic (ROC) analysis of the five-year recurrence-free survival indicated that the comprehensive risk score (CRS) of E-PASS predicted postoperative recurrence.

Background: Adjuvant chemotherapy for stage II colorectal cancer (CRC) is considered appropriate for patients with risk factors for recurrence, rather than for all patients uniformly. However, the risk factors for recurrence remain controversial, and there is limited information, especially for elderly patients. The Geriatric Nutritional Risk Index (GNRI) is widely used as a simple nutritional screening tool in the elderly and is associated with cancer prognosis and recurrence.
