Effect of density of state on isotope effect exponent of two-band superconductors

, 2005
The exact formula of Tc's equation and the isotope effect exponent of two-band s-wave superconductors in weak-coupling limit are derived by considering the influence of two kinds of density of state : constant and van Hove singularity.

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。

Domain associated with zinc fingers‐containing NF90‐NF45 complex inhibits m6A modification of primary microRNA by suppressing METTL3/14 activity

FEBS Open Bio, EarlyView.
NF90–NF45 functions as a negative regulator of methyltransferase‐like 3/14 (METTL3/14)‐mediated N6‐methyladenosine (m6A) modification on primary microRNAs (pri‐miRNAs). NF90–NF45 binds to anti‐oncogenic pri‐miRNAs and inhibits their m6A modification, thereby suppressing the biogenesis of anti‐oncogenic miRNAs.

Meta‐analysis fails to show any correlation between protein abundance and ubiquitination changes

FEBS Open Bio, EarlyView.
We analyzed over 50 published proteomics datasets to explore the relationship between protein levels and ubiquitination changes across multiple experimental conditions and biological systems. Although ubiquitination is often associated with protein degradation, our analysis shows that changes in ubiquitination do not globally correlate with changes in ...

Discovery and Targeted Proteomic Studies Reveal Striatal Markers Validated for Huntington's Disease

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Clinical trials for Huntington's disease (HD) enrolling persons before clinical motor diagnosis (CMD) lack validated biomarkers. This study aimed to conduct an unbiased discovery analysis and a targeted examination of proteomic biomarkers scrutinized by clinical validation. Methods Cerebrospinal fluid was obtained from PREDICT‐HD and

Isotope effect on the superfluid density in conventional and high-temperature superconductors

, 2010
We investigate the isotope effect on the London penetration depth of a superconductor which measures $n_S/m^*$, the ratio of superfluid density to effective mass.
