Oxygen isotope ecology of recent planktic foraminifera at the central Walvis Ridge (SE Atlantic) [PDF]
, 2005 Above the Walvis Ridge, in the SE Atlantic Ocean, we collected living plantkic foraminifera from the upper water column using depth stratified plantkon tows. The oxygen isotope composition (

Isomeric Ag14 Nanoclusters With Distinct Photophysical and Nanomechanical Properties
Advanced Science, EarlyView.Ligand‐shell isomerism in atomically precise Ag14 nanoclusters is demonstrated to regulate core distortion, photoluminescence, and mechanical properties. Subtle changes in phosphine ligand arrangement drive a pronounced emission shift from green to red and alter crystal rigidity, revealing a direct structure‐property correlation that offers new design ...

Cancer‐Associated BCL‐2 Mutants Reveal Mechanisms Towards Venetoclax Resistance
Advanced Science, EarlyView.Venetoclax (VEN) resistance in chronic lymphocytic leukemia arises from diverse BCL2 mutations. We map mechanisms contributing to VEN resistance across common BCL‐2 variants. G101V and D103Y reduce drug binding and increase sequestration of pro‐apoptotic proteins. V156D blocks VEN allosterically.

Isotope Effect and Isotope Separation
Nippon kagaku zassi, 1968 同位体物質の換算分配関数比の値を, 量子統計論に基づき, 分子振動スペクトルからの知見を用いて算定した。これらの結果は同位体分離の研究に一つの基礎を与える。同位体物質が二相に分配するとき, 化学反応が同位体の分離効果にどのような影響をおよぼすかについて理論的な考察(二相分配理論) を行なった。導出された基礎式から, どのような系がもっとも分離効果が大きいかを知ることができる。二三の簡単な系について, この理論を展開した。さらにイオン交換樹脂を用いて, 実際にリチウム, 窒素, 銅, ウラン同位体の分離実験を行ない, 相分配理論によって解析を試みた。

Advanced Science, EarlyView.This study reveals that NOTCH2NLC transcript variant 2 generates PolyGN2C‐iso2, an aggregating protein present within intranuclear inclusions of NIID patient tissues. A novel mouse model expressing PolyGN2C‐iso2 recapitulates white matter abnormalities and cognitive deficits, mechanistically linked to mitochondrial dysfunction. These findings support a

Advanced Science, EarlyView.Asymmetric single‐atom metal‐nitrogen‐carbon catalysts modulate the non‐radical pathway during peroxymonosulfate (PMS) activation. A fundamental contrast was revealed between diffusible singlet oxygen (1O2) and non‐diffusible electron‐transfer pathways (ETP) in antibiotic resistance gene (ARG) degradation.

Toarcian oceanic anoxic event: An assessment of global causes using belemnite C isotope records [PDF]
, 2005 Two hypotheses have been proposed to explain simultaneous large negative excursions (up to 7% PeeDee belemnite) in bulk carbonate (delta(13)C(carb)) and organic carbon isotope records (delta(13)C(org)) from black shales marking the Toarcian oceanic ...
