Characterization of individual ice residual particles by the single droplet freezing method: a case study in the Asian dust outflow region [PDF]

Atmospheric Chemistry and Physics, 2018
In order to better characterize ice nucleating (IN) aerosol particles in the atmosphere, we investigated the chemical composition, mixing state, and morphology of atmospheric aerosols that nucleate ice under conditions relevant for mixed-phase clouds.

The Use of Ultrasound in Shaping the Properties of Ice Cream with Oleogel Based on Oil Extracted from Tomato Seeds

Applied Sciences, 2022
In this study, the possibility of using ultrasound technology as an alternative to traditional pasteurization and homogenization in ice cream production was presented. Three types of ice cream with different proportions of oleogel (5, 6, and 7%) prepared

Cell surface interactome analysis identifies TSPAN4 as a negative regulator of PD‐L1 in melanoma

Molecular Oncology, EarlyView.
Using cell surface proximity biotinylation, we identified tetraspanin TSPAN4 within the PD‐L1 interactome of melanoma cells. TSPAN4 negatively regulates PD‐L1 expression and lateral mobility by limiting its interaction with CMTM6 and promoting PD‐L1 degradation.

Broadband spectroscopy of astrophysical ice analogues

Astronomy & Astrophysics, 2019
Context.Reliable, directly measured optical properties of astrophysical ice analogues in the infrared and terahertz (THz) range are missing from the literature. These parameters are of great importance to model the dust continuum radiative transfer in dense and cold regions, where thick ice mantles are present, and are necessary for the interpretation ...

Plecstatin inhibits hepatocellular carcinoma tumorigenesis and invasion through cytolinker plectin

Molecular Oncology, EarlyView.
The ruthenium‐based metallodrug plecstatin exerts its anticancer effect in hepatocellular carcinoma (HCC) primarily through selective targeting of plectin. By disrupting plectin‐mediated cytoskeletal organization, plecstatin inhibits anchorage‐dependent growth, cell polarization, and tumor cell dissemination.

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Crystalline hydrogen bonding of water molecules confined in a metal-organic framework

Communications Chemistry, 2022
Determining the spatial ordering and hydrogen bonding dynamics of confined water molecules within nanopores remains challenging. Here, Raman spectroscopy and crystallographic studies show ice-like spatial ordering of unbound water molecules within the ...

Hands‐on protocol for preparing water‐soluble fractions from agri‐food samples for NMR‐based metabolomics analysis

FEBS Open Bio, EarlyView.
This research protocol outlines a workflow for nuclear magnetic resonance (NMR)‐based metabolomics in the agri‐food sector. Using two case studies—strawberry leaves (solid matrix) and wine (liquid matrix)—it details the procedures for sample preparation, data acquisition, and processing.

Impurity Analysis and Microstructure Along the Climatic Transition From MIS 6 Into 5e in the EDML Ice Core Using Cryo-Raman Microscopy

Frontiers in Earth Science, 2019
Impurities in polar ice cores have been studied so far mainly for the purpose of reconstructions of past atmospheric aerosol concentrations. However, impurities also critically influence physical properties of the ice matrix itself.

Two-dimensional infrared spectroscopy of neat ice I_h

Physical Chemistry Chemical Physics, 2016
The assignment of the distinct peaks observed in the OH stretch lineshape of ice Ih is controversial. In contrast to a resent experimental interpretation we find that excitonic cross peaks exist between the dominant exciton states. Opposed to common cases the transition dipole directions between these coupled states are uncorrelated.
