CDK4/6 inhibitor plus endocrine therapy for advanced breast cancer: results from a web-based survey in Japan.

Background: Though efforts have been made toward standardizing access to quality cancer care in Japan, there are still geographical and institutional disparities in the level of cancer care availability. We investigated the utilization of cyclin-dependent kinase 4/6 inhibitors plus endocrine therapy (CDK4/6i+ET) as first-line (1 L) treatment for hormone receptor-positive (HR+)/human epidermal growth factor receptor 2-negative (HER2-) advanced breast cancer (ABC) in Japan.

Research Design And Methods: This cross-sectional survey included physicians who had treated ≥3 1 L patients with HR+/HER2- ABC in the past year.

Identifying Risk Factors of Major Adverse Cardiac Events in Patients With Ulcerative Colitis: A Retrospective Japanese Claims Data Analysis.

Background And Aim: We conducted a retrospective study to identify incidence rates and potential risk factors of major adverse cardiac events (MACE) in Japanese patients with ulcerative colitis (UC), as existing data are scarce, inconsistent, and provide limited representation of the real-world situation of MACE in Japan.

Methods: We utilized administrative claims data, collected between January 2013 and December 2022, from Medical Data Vision, Japan. Patients (aged ≥ 20 years) diagnosed with UC within ± 1 month of the prescription date during the study period were included in the incident cohort.

Multifunctional composite film of curcumin Pickering emulsion stabilized by lignocellulose nanofibrils isolated from bamboo shoot shells for monitoring shrimp freshness.

Concerns about food safety and environmental impact from chemical surfactants have prompted interest in natural lignocellulosic materials as alternatives. In this study, we combined hydrated deep eutectic solvent (DES) pretreatment with ultrasound treatment to prepare lignocellulosic nanofibrils (LCNF) from bamboo shoot shells with appropriate surface properties for stabilizing Pickering emulsions. The pretreatment intensity effectively modulated the surface characteristics of LCNF, achieving desirable wettability through lignin retention and in-situ esterification.

Transcription factor PagMYB31 positively regulates cambium activity and negatively regulates xylem development in poplar.

Wood formation involves consecutive developmental steps, including cell division of vascular cambium, xylem cell expansion, secondary cell wall (SCW) deposition, and programmed cell death. In this study, we identified PagMYB31 as a coordinator regulating these processes in Populus alba × Populus glandulosa and built a PagMYB31-mediated transcriptional regulatory network. PagMYB31 mutation caused fewer layers of cambial cells, larger fusiform initials, ray initials, vessels, fiber and ray cells, and enhanced xylem cell SCW thickening, showing that PagMYB31 positively regulates cambial cell proliferation and negatively regulates xylem cell expansion and SCW biosynthesis.
