Prognostic Impact of Preoperative Left Ventricular Systolic Dysfunction in Older Adult Patients With Gastric Cancer.

Background/aim: The effect of left ventricular systolic dysfunction (LVSD), a risk factor for postoperative mortality, in older adult patients with gastric cancer has not been fully elucidated. This study aimed to evaluate the impact of low preoperative left ventricular ejection fraction (EF) on short- and long-term outcomes in older adult patients with gastric cancer.

Patients And Methods: This retrospective study enrolled 237 older adult patients with gastric cancer (≥75 years old) who underwent preoperative echocardiography and curative gastrectomy.

Enhanced Stability of α-Mangostin-Rich Extract and Selective Cytotoxicity against Cancer Cells via Encapsulation in Antioxidant Nanoparticles (AME@Nano).

α-Mangostin-rich extract (AME) shows promise as a functional ingredient for cancer chemotherapy. Here, we encapsulated AME in our originally designed antioxidant nanoparticles (Nano) to increase its solubility and prevent oxidative degradation (AME@Nano). In this study, two types of self-assembled polymers containing nitroxide radicals were engineered.

Relationship between joint structure of the first tarsometatarsal joint and its degeneration.

This study aimed to elucidate the relationship between joint structures of the first tarsometatarsal and articular facet degeneration. A total of 100 feet from 50 cadavers were examined. The articular facets of the first metatarsal and medial cuneiform were categorized into four types based on the superior and inferior facets' separation, and the formation of the inferior lateral facet on the lateral plantar prominence: Type I, a single facet with no separation or inferior lateral facet; Type II-a, two facets with separation but no inferior lateral facet; Type II-b, two facets, no separation, but with an inferior lateral facet; Type III, three facets with separation and an inferior lateral facet.

Assessing the combined impact of fatty liver-induced TGF-β1 and LPS-activated macrophages in fibrosis through a novel 3D serial section methodology.

Non-alcoholic steatohepatitis (NASH), caused by fat buildup, can lead to liver inflammation and damage. Elucidation of the spatial distribution of fibrotic tissue in the fatty liver in NASH can be immensely useful to understand its pathogenesis. Thus, we developed a novel serial section-3D (SS3D) technique that combines high-resolution image acquisition with 3D construction software, which enabled highly detailed analysis of the mouse liver and extraction and quantification of stained tissues.
