Transactions of The Electrochemical Society, 1940 In amperometric titrations the current passing through the titration cell is measured. These titrations require very little time and are applicable to very dilute solutions. Characteristic current‐voltage curves are shown. It is expected that amperometric titrations will find at least as extensive application as potentiometric titrations do now in ...

The titrating conditions in the potentiometric titration of zinc
BUNSEKI KAGAKU, 1964 硫酸酸性におけるフェロシアン化カリウムによる亜鉛の定量を,さまざまな滴定条件のもとに,白金-タングステン双金属電極を用いて電位差滴定を行ない,滴定に及ぼす諸影響を検討した.20℃では硫酸濃度,硫酸アンモニウム濃度によって終点の滴定量が異なるが,滴定溶液の容積100mlあたり硫酸濃度範囲0～0.05N,硫酸アンモニウム20gで一定の滴定速度のもとに行なうと,終点までの滴定量の再現性および電位差滴定曲線がともに良好で,終点における電位差変化が大きい.亜鉛濃度0.0025～0.0125Mの溶液を,滴定誤差約+1.5%で定量することができる.60℃ではすみやかに終点に達し,硫酸濃度,硫酸アンモニウム濃度,滴定時間の影響はより小さくなるが,終点における電位差変化が小さい.滴定誤差は約-1.2%である.

Targeting the EpCAM‐AXL axis to overcome drug resistance in lung cancer
Molecular Oncology, EarlyView.Lung cancer cells often evade therapy by hijacking signaling pathways. We reveal that cleaved EpCAM (sEpCAM) stabilizes the oncogenic protein AXL, driving NF‐κB and STAT3‐mediated chemoresistance. This EpCAM‐AXL axis identifies a high‐risk patient subset with poor prognosis.

Adenosine triphosphate as a modulator of protein interactions and stability
FEBS Open Bio, EarlyView.ATP is best known as the cell's energy currency, but it also shapes how proteins fold, interact, aggregate and form biomolecular condensates. This review explains the emerging physical principles behind these effects, including weak binding to charged protein regions, magnesium‐dependent behaviour and concentration‐dependent control of protein ...

A minimal cellulosome‐like system in Cellulosilyticum lentocellum
FEBS Open Bio, EarlyView.Cellulose‐degrading bacteria typically use cellulosomes, large multi‐enzyme complexes on a scaffold protein. In Cellulosilyticum lentocellum, we characterise a far smaller arrangement, a single scaffold bound to one cellulase through a single cohesin‐dockerin interaction.

FEBS Open Bio, EarlyView.Human ABCE1 cannot functionally replace its yeast ortholog. Yeast–human chimera analysis identified NBD1 as a major interspecies barrier. Genetic screening yielded hABCE1 revertants that rescue yeast viability but fail to suppress aberrant translation reinitiation in the 3′ UTR.
