Liquid membrane extraction of bio-active amphiphilic substances: Recovery of surfactin [PDF]
, 2008 The interest of application of liquid membrane (pertraction) processes for recovery of biosurfactants from aqueous media was demonstrated. Transport of pure surfactin in three-liquid-phase system was studied.

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative

Resistive liquid-vapor surface sensors for liquid nitrogen and hydrogen
, 1992 Ten resistance thermometers were tested as point sensors for detecting the liquid-vapor interface in liquid nitrogen and liquid hydrogen. Test results showed that most could be made to detect the liquid surface and lead orientation can be important.

Zhongguo youzhi, 2022 采用高效液氮加注技术对葵花籽油进行灌装，并与气氮加注、气液氮混合加注技术进行对比，研究其对葵花籽油品质和产品包装的影响。结果表明：3种充氮方式样品的酸值和过氧化值变化趋势基本一致；液氮加注样品常温储藏5个月后酸值（KOH）和过氧化值分别为0.07 mg/g和1.45 mmol/kg，与常温储藏相比，液氮加注样品45 ℃储藏5个月后酸值无差别，过氧化值稍有降低，为130 mmol/kg；液氮加注和气液氮混合加注样品初始及储藏过程中的过氧化值比气氮加注样品的稍高；常温下3种充氮方式样品的初始残氧值相差不大，

FEBS Letters, EarlyView.Structural and biochemical characterisations show that the planar cell polarity (PCP) protein Inturned harbours a unique PDZ‐like domain that does not bind canonical PDZ‐binding motifs (PBMs) like that of another PCP protein Vangl2. In contrast, the apical‐basal polarity protein Scribble contains four PDZ domains that bind Vangl2, but one PDZ domain ...

Calpain small subunit homodimerization is robust and calcium‐independent
FEBS Letters, EarlyView.Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.

The impact of thawing on the quality attributes of swimming crab (Portunus trituberculatus) frozen by liquid nitrogen freezing [PDF]
, 2020 Effects of air thawing (AT), refrigerator thawing (RT), water immersing thawing (WIT), lotic water thawing (LWT), and microwave thawing (MT) on the quality of swimming crab by liquid nitrogen freezing were investigated.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

pH‐mediated activation of the lysosomal arginine sensor SLC38A9
FEBS Letters, EarlyView.Cells monitor nutrient levels via the lysosomal transporter SLC38A9 to activate the mechanistic target of rapamycin complex 1 (mTORC1). This study reveals that SLC38A9 function is regulated by pH. We identified histidine 544 as a critical pH sensor that undergoes conformational changes to control amino acid efflux from lysosomes; therefore, it ...
