A Dual‐Function Mitochondria‐Targeted Polyoxometalate Nanomicelle Boosts Pyroptosis‐Dependent Antitumor Immune Response in Triple‐Negative Breast Cancer

open access: yesRare Metals, Volume 45, Issue 5, May 2026.
ABSTRACT The efficacy of immunotherapy in triple‐negative breast cancer (TNBC) is often limited, whereas the immunotherapeutic potential of pyroptosis is frequently undermined by a compensatory surge in mitophagy. To address this challenge, this study developed a reactive oxygen species (ROS)‐responsive and mitochondria‐targeted nanomicelle (POM@CTT ...

乳母の衰退 : 明治期以降の乳母制度 [PDF]

open access: yes, 2010
2010-03今日働く母親の子育てや少子化といった問題は大きな社会問題である。歴史を振り返れば子育てに関して、日本だけでなく世界の多くの国が「乳母」という育児法を生み出している。日本では「乳母の制度」は王朝、貴族の時代、また武士の時代では権力と富を持つ者たちのためのものだったが、時代が下がるにつれて広がりを見せ、江戸時代には「御乳母日傘」で育つことは江戸っ子の条件でもあったという。貴族や武士の時代、乳母は権力者の傍にいたため、乳母の職は、自身や一族が権力を獲得する要石ともなった ...

用于稠油污水处理的高效反相破乳剂的合成

open access: yesGongye shui chuli, 2007
稠油污水乳化严重,水质复杂,破乳处理是稠油污水处理中的关键环节。在分析辽河欢四联稠油污水特点的基础上采用环氧氯丙烷、二甲胺和交联剂乙二胺合成了一种聚阳离子季铵盐型反相破乳剂HEY-M,该破乳剂具有强的压缩双电层和击破界面膜作用。HEY-M破乳剂除油效率<96%,是一种高效稠油污水反相破乳剂。

Impacts of Human Development on Wildlife Use of Corridors in Botswana 人类开发对博茨瓦纳野生动物廊道利用的影响

open access: yesIntegrative Conservation, Volume 5, Issue 1, Page 164-171, March 2026.
This study examined the effect of landscape‐scale human impact on wildlife in Botswana. We examined how species use wildlife corridors in two different human‐dominated landscapes. We identified differences in temporal overlap between wildlife and humans across both landscapes, which is fundamental to consider in both current and future conservation ...

Predicting Spatial Distributions of Mammalian Predation on Translocated Wild Turkeys in Agriculturally Dominated Landscapes 在以农业为主的景观中哺乳动物对易地放归的野生火鸡捕食的空间分布预测

open access: yesWildlife Letters, Volume 3, Issue 3, Page 91-98, September 2025.
The edge densities of cropland, developed land, and water bodies (panel a) predict the spatial probability of mammalian predation on wild turkeys (panel b) using Mahalanobis distance factor analysis in Quitman County, Mississippi, United States. The three habitat fragmentation variables are represented by three arrows, respectively.
