From Policy Neglect to Research Agenda: Administrative Burdens and Donor‐Conceived Mobilization

Policy Studies Journal, Volume 54, Issue 4, November 2026.
ABSTRACT Donor‐conceived adults are a growing population, mobilizing against the very regulatory arrangements that determined the terms into which they were conceived. In Canada and the United States, where donor conception remains persistently under‐regulated, gamete donation policy has historically prioritized the presumed needs of donors, recipient ...

Lanthanide Nanoparticles With Dual Enzyme Mimetic Activities for Targeted Treatment of Gram‐Negative Bacterial Infections

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT Gram‐negative (G−) bacterial infections, fueled by intrinsic antibiotic resistance stemming from their unique outer membrane architecture, pose a critical global clinical challenge. This study introduces a pioneering dual‐enzyme‐mimetic nanotherapy based on NaYbF4 nanoparticles (NaYbF4 NPs) that achieves synergistic antibacterial and anti ...

ヘパリンで受精能獲得したヒツジ精子の体外受精後の胚発生 [PDF]

, 2002
凍結融解精子を用いたヒツジ体外受精系において、精子受精能獲得処理の際のヘパリンの添加が、受精後の胚の発生に対してどのような影響をおよぼすのかを検討した。凍結融解精子は融解後ヘパリン添加/無添加のBO 液で希釈・洗浄され、1時間の炭酸ガス培養器内での培養の後、体外成熟されたヒツジ卵子へ授精された。授精後23時間で卵子を裸化し、さらに7日間顆粒膜細胞と共培養した。共培養中、授精後48時間目に卵割の状況を、授精後8日目に胚盤胞期胚への発育の状況をそれぞれ観察した。授精後48時間目における卵割の状況は ...

Bias‐Gated Functional Switching on Ti3C2/Cu2O/Au@Ag Heterostructure‐Based Photoelectrochemical Platform: OFF–ON Signal Transduction Detection and Efficient Degradation of Ciprofloxacin

Rare Metals, Volume 45, Issue 10, October 2026.
ABSTRACT A central challenge in high‐performance photoelectrochemical (PEC) systems is mitigating the intrinsic limitations in photogenerated carrier separation and transport, while enabling efficient broad‐spectrum solar harvesting. Inspired by the synergistic effect between plasmonic resonance and heterojunction built‐in electric fields, a ternary ...

萼花臂尾轮虫交配行为和受精作用研究

, 2000
萼花臂尾轮虫的交配行为大致可分为 5个阶段。除雌雄性比为 1∶ 2和 1∶ 3时混交雌体的受精率为 1 0 0 %外 ,其余性比下混交雌体的受精率皆无显著的差异。可受精的混交雌体百分率和具受精能力的雄体百分率皆随年龄的增大而下降。所有的混交雌体在出生后的 4 h内均易于受精 ;以后随着龄长 ( X,h)的增加 ,可受精的混交雌体百分率 ( Y,% )呈非线性下降 :Y=1 66.6386-1 7.81 3X+0 .4 837X2。当龄长达 1 8h时 ,所有的混交雌体皆不易受精。雄体在出生后的 8h内

Real‐time gestational‐age estimation at 11–13 weeks using artificial intelligence on non‐targeted ultrasound sweeps

Ultrasound in Obstetrics &Gynecology, Volume 68, Issue 4, Page 510-517, October 2026.
ABSTRACT Objective To assess the accuracy of gestational‐age estimation using an artificial intelligence (AI) system applied to non‐targeted ultrasound sweeps at 11 + 0 to 13 + 6 weeks' gestation. Methods This was an observational study of singleton pregnancies undergoing routine first‐trimester ultrasound in July 2025 to August 2025.

The New World Order and National Security Dynamics of African States: Case Studies of Cameroon and Mali

World Affairs, Volume 189, Issue 4, Winter 2026.
ABSTRACT The move from unipolarity to a fluid and contested multipolar world order has significantly changed the way African nations form national security policy due to changes in the nature of the strategic environment of those states. Much of the literature has focused on how the actions of major world powers ‐ the United States, China and Russia ...

Role of funders in embedding tests in conservation practice

Conservation Biology, Volume 40, Issue 5, October 2026.
Abstract Effective conservation practice requires decisions based on reliable and relevant evidence, but significant gaps in the evidence base exist. Incorporating well‐designed tests of the effectiveness of interventions for biodiversity in conservation projects is one of the best ways to scale up the rate of evidence generation.
