The feasibility and short-term safety of single-site hysterectomy: a retrospective cohort study of a novel robotic platform.

Background: Robotic-assisted laparoscopic single-site hysterectomy is popular among patients and surgeons due to good cosmetic outcomes and fast recovery. However, questions remain such as loss of triangulation and instrument collision. Our aim is to test the feasibility and safety of a purpose-designed single-site robotic surgical platform mainly in hysterectomies.

Interplay between A-site and oxygen-vacancy ordering, and mixed electron/oxide-ion conductivity in = 1 Ruddlesden-Popper perovskite SrNdZnO.

Oxygen vacancies in Ruddlesden-Popper (RP) perovskites (PV) [AO][ABO] play a pivotal role in engineering functional properties and thus understanding the relationship between oxygen-vacancy distribution and physical properties can open up new strategies for fine manipulation of structure-driven functionalities. However, the structural origin of preferential distribution for oxygen vacancies in RP structures is not well understood, notably in the single-layer ( = 1) RP-structure. Herein, the = 1 RP phase SrNdZnO was rationally designed and structurally characterized by combining three-dimensional (3D) electron diffraction and neutron powder diffraction.

Genotype-by-Environment Effects of Cis-Variations in the Atgl Promoter Mediate the Divergent Pattern of Phenotypic Plasticity for Temperature Adaptation in Two Congeneric Oyster Species.

Phenotypic plasticity plays an essential role in adaptive evolution. However, the molecular mechanisms of how genotype-by-environment interaction (G × E) effects shape phenotypic plasticity in marine organisms remain poorly understood. The crucial temperature-responsive trait triacylglycerol (TAG) content and its major gene adipose triglyceride lipase (Atgl) expression have divergent plastic patterns in two congeneric oyster species (Crassostrea gigas and Crassostrea angulata) to adapt to relative-cold/northern and relative-warm/southern habitats, respectively.

Virtual MR Elastography and Multi-b-value DWI Models for Predicting Microvascular Invasion in Solitary BCLC Stage A Hepatocellular Carcinoma.

Rationale And Objectives: To evaluate the performance of virtual MR elastography (vMRE) for predicting microvascular invasion (MVI) in Barcelona Clinic Liver Cancer (BCLC) stage A (≤ 5.0 cm) hepatocellular carcinoma (HCC) and to construct a combined nomogram based on vMRE, multi-b-value DWI models, and clinical-radiological (CR) features.

Methods: Consecutive patients with suspected HCC who underwent multi-b-value DWI examinations were prospectively collected.

Marital Status as a Moderator: Exploring the Relationship between Social Engagement and Depressive Symptoms in China's Older Adult Population.

Objective: This study aims to explore the complex relationship between social engagement and depressive symptoms among older adults in China, focusing particularly on the moderating role of marital status.

Methods: This study used data from the latest Chinese Longitudinal Healthy Longevity Survey (CLHLS). The analysis used the latent class analysis to delineate personality clusters and hierarchical linear regression, supplemented by the PROCESS macro, to investigate the effects of social engagement and marital status on depressive symptoms.
