Roles of Interfacial Functions in Analytical Chemistry. Construction of a scanning near-field optical microscope using a white-light source.

BUNSEKI KAGAKU, 1998
キセノンランプからの白色光を光源とし,光走査トンネル顕微鏡方式の走査型近接場光学顕微鏡(SNOM)を試作した.微小領域の透過スペクトルを得るための基礎実験として,銅フタロシアニン及び金の2種類の薄膜試料に関して透過スペクトルを得ることを試みた.SNOMで得られた透過スペクトルを市販の分光光度計による測定結果と比較したところ,銅フタロシアニンの薄膜に対しては両者のスペクトルは良く一致したが,金の薄膜の測定結果はSNOMと分光光度計とで反対の傾向を示した.両者の測定結果の違いを金の薄膜に励起される表面プラズモンによって説明した.

Pathways and pitfalls: a qualitative study of student experiences in biomedical science education

FEBS Open Bio, EarlyView.
Biomedical science students from underrepresented backgrounds face barriers including financial strain, disrupted laboratory access and cultural exclusion. Peer networks provide vital support when institutional systems are difficult to navigate. To create inclusive learning environments and achieve academic success, educators should blend active, hands‐

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

FEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

Malformin A1–mediated cytotoxicity in ovarian cancer cells occurs through pyroptosis and autophagy

FEBS Open Bio, EarlyView.
This study investigated the effects of the natural compound Malformin A1 (MA1) on the cytoskeleton that regulates cell proliferation and migration. Disruption of the cytoskeleton can impair these processes and promote cancer cell death. MA1 disrupted cytoskeletal organization, induced DNA damage, inflammation, activated autophagy, and pyroptosis ...

A Deep Analytical Investigation of the Aroma Chemistry of Incrocio Bruni 54 and Its Differentiation from Italian White Varieties

Fermentation
Incrocio Bruni 54 is a little-known white grape variety developed in the Marche region (Italy) from a cross between Verdicchio and Sauvignon Blanc to combine aromatic freshness with structure. In light of the growing interest in minor and autochthonous cultivars, this study provides the first comprehensive chemical characterization of the aroma profile

Evaluating the effect of γ‐oryzanol on MASLD pathology using a medaka fish model

FEBS Open Bio, EarlyView.
This study explores a liver disease called MASLD, which is increasing worldwide and can lead to serious damage. Researchers used medaka fish instead of rodents to test a food compound, γ‐oryzanol. Fish fed this compound had less liver fat and healthier gut bacteria.
