Cu‐Enhanced Medium‐Entropy TiZrCoCrMo Alloys: Balancing Superior Antibacterial and Osteogenic Properties for Orthopedic Implants

open access: yesRare Metals, Volume 45, Issue 2, February 2026.
ABSTRACT This study introduces novel nonequiatomic TiZrCoCrMoCux (x = 0, 5, 10; at%) medium‐entropy alloys (MEAx) tailored for orthopedic implants, synergistically combining the biocompatibility of Ti‐based alloys, the wear resistance of CoCrMo alloys, and the antibacterial/osteogenic attributes of Cu. The alloy's microstructure, mechanical properties,

Comparison of ultrasound with computed tomography and whole‐body diffusion‐weighted MRI in prediction of surgical outcome using ESMO‐ESGO criteria in patients with tubo‐ovarian carcinoma: prospective ISAAC study

open access: yesUltrasound in Obstetrics &Gynecology, Volume 67, Issue 2, Page 207-219, February 2026.
ABSTRACT Objective To test the non‐inferiority of extended abdominopelvic ultrasound examination compared with contrast‐enhanced computed tomography (CT) and whole‐body diffusion‐weighted magnetic resonance imaging (WB‐DWI/MRI) in discriminating preoperatively between resectable and non‐resectable disease based on the European Society for Medical ...

Sulfur‐Doped Carbon Matrix‐Coated Co1‐xS/Ni0.96S@NC Rhombic Cubes Significantly Enhanced the Storage Performance and Kinetics of Lithium/Sodium‐Ion Batteries

open access: yesRare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT Metal sulfide, as a type of lithium/sodium‐ion battery material, possesses merits such as high capacity and low cost. Nevertheless, it is prone to structural changes during the cycling process, leading to volume changes and affecting electrochemical performance.

Thermohydrogen‐Induced α→β Phase Transition and Interfacial Aggregation: A Diffusion Bonding Mechanism for Ti65 Alloy at Low Temperatures

open access: yesRare Metals, Volume 45, Issue 1, January 2026.
ABSTRACT Diffusion bonding (DB) of near‐α titanium alloys requires high temperatures, which can cause grain coarsening, structural deformations, and degradation of the workpiece's mechanical characteristics. In this study, thermal hydrogen processing (THP) was applied to Ti65, combined with selective magnetron sputtering of a Ti‐Al thin film to promote

Unlocking grass leaf development: foundations for tunable cereal design

open access: yesNew Phytologist, Volume 248, Issue 4, Page 1655-1676, November 2025.
Summary The grass leaf plays a critical role in global food security, generating the carbon stores in cereal grains, which provide > 50% of global calories. As the global population grows, there is an urgent need to increase food production using fewer resources and to develop more resilient agricultural systems to withstand variable climate conditions

Combined first‐trimester screening and invasive diagnostics for atypical chromosomal aberrations: Danish nationwide study of prenatal profiles and detection compared with NIPT

open access: yesUltrasound in Obstetrics &Gynecology, Volume 64, Issue 4, Page 470-479, October 2024.
ABSTRACT Objectives Our aim was to examine the prenatal profiles of pregnancies affected by an atypical chromosomal aberration, focusing on pathogenic copy‐number variants (pCNVs). We also wanted to quantify the performance of combined first‐trimester screening (cFTS) and a second‐trimester anomaly scan in detecting these aberrations. Finally, we aimed

结核分枝杆菌生物被膜体外模型的建立

open access: yesZhongguo shiyan zhenduanxue, 2017
目的本试验探讨如何建立结核菌生物被膜体外模型。方法选取生长良好的非耐药结核菌在罗氏固体培养基中复苏,在7H9OADC培养基中重新培养1周,使其活力相同,配置苏通培养基分别在烧瓶及孔板中培养结核菌观察生物膜的生长情况。结果 36株结核菌在孔板中培养时使用封口膜的全部培养出生物膜,而未使用封口膜的均培养失败。烧瓶中培养:在培养3周时需要松开瓶盖,否则生物膜生长不良。时间:培养2周时可看到有生物膜出现,5周时生物膜培养成熟。结论结核菌有生物被膜,通过体外培养可以成功获得。

肠道微生物及其代谢产物与心力衰竭相关性研究现状

open access: yesZhongguo shiyan zhenduanxue, 2021
肠道微生物参与了多种疾病的发生和进展,心力衰竭也被证实是一种与肠道功能改变有关的导致多脏器衰竭的炎症性疾病[1-2]。心力衰竭引发的血流动力学的改变使肠黏膜屏障功能受损,肠道微生物及其代谢产物得以移位进入血液循环,从而触发机体的免疫炎症反应,加重了心衰患者体内的炎症负担[3]。因此,通过提高对有关肠道微生物及其代谢产物在心力衰竭发病机制中的认识,对制定新的心力衰竭治疗策略和促进个性化治疗是有必要的。

Olfactory receptors in Bactrocera species for sustainable fruit fly management: A review and future perspectives

open access: yesPhysiological Entomology, Volume 49, Issue 2, Page 67-90, June 2024.
Olfactory receptor neurons (ORNs) in insect antennae project axons to glomeruli in the antennal lobe for odor processing by local interneurons. Uniglomerular projection neurons (PNs) relay processed odor information to the mushroom body and lateral horn.
