The First Chalcone Derivatives of Valine-Based Spiro-Cyclotriphosphazenes: In Vitro Cytotoxic Properties, Molecular Docking and DNA Damage Mechanism Studies. [PDF]
J Biochem Mol ToxicolThis study synthesizes and evaluates hybrid cyclotriphosphazene compounds for cancer treatment. The compounds exhibited significant cytotoxicity and genotoxicity against A2780 and Caco‐2 cell lines, inducing DNA damage and apoptosis, with molecular docking suggesting their potential as targeted inhibitors for cancer therapy.

physica status solidi (b), EarlyView.Novel Cu–Ni–Sn–S nanocrystals (NCs) stabilized with thioglycolic acid are synthesized in aqueous solutions. The structural and optical properties of Cu–Ni–Sn–S NCs are examined in colloidal solutions and thin films and compared to those of Cu–Zn–Sn–S NCs. The absorption coefficient is α > 104 cm−1 at 400 nm with an estimated Eg≈2.2 eV.

Detection of Hypoxia in Human Brain Tumor Xenografts Using a Modified Comet Assay
Neoplasia: An International Journal for Oncology Research, 2003 We used the standard comet assay successfully to generate in vitro dose-response curves under oxic and hypoxic conditions. We then made mixtures of cells that had been irradiated with 3 and 9 Gy of X-rays to simulate two subpopulations in a tumor, but ...

Strong CO$^+$ and N$_2^+$ Emission in Comet C/2016 R2 (Pan-STARRS) [PDF]
ApJ Letters 854, L10, 2018, 2018 We report on imaging and spectroscopic observations of comet C/2016~R2 (Pan-STARRS) obtained with the 0.8\,m and 2.7\,m telescopes of McDonald Observatory in November and December 2017 respectively. The comet was at a heliocentric distance greater than 3\,{\sc au} during both sets of observations. The images showed a well-developed tail with properties

Small, EarlyView.Protease activity of cancer‐derived extracellular vesicles is quantified using a single microelectrode array in a microfluidic device to create two different electrokinetic‐based analyte collection mechanisms. First, dielectrophoresis is used to recover and purify EVs from plasma followed by electrophoresis to quantify protease activity using cleavable

Pulmonary scan in evaluating alveolar-interstitial syndrome in ER
Emergency Care Journal, 2006 Diffuse comet-tail artifacts at lung ultrasound are due to thickened interlobular septa and extravascular lung water. This condition is typical of the alveolar-interstitial syndrome due to pulmonary edema, diffuse parenchymal lung disease or ARDS. Aim of

Prospects for the Crossing by Earth of Comet C/2023 A3 Tsuchinshan-ATLAS's Ion Tail [PDF]
The Earth will pass approximately downstream of the previous position of comet C/2023 A3 (Tsuchinshan-ATLAS) during 2024 October 10-13. We predict that spacecraft at the Sun-Earth Lagrange Point 1, L1, have a significant likelihood to detect pickup ions from the comet, as well as changes in the solar wind associated with the crossing of the comet's ion

Clinical manifestations of the comet tail artifact.
Journal of ultrasound in medicine, 1983 The comet tail artifact appears as a dense tapering trail of echoes just distal to a strongly reflecting structure. This reverberation type of artifact occurs when there is a marked difference in acoustic impedances between an object and its surround ...

Micrometer‐Sized Liposome‐Based Systems: A Hierarchical Breakdown
ChemSystemsChem, EarlyView.Micrometer‐sized liposomes (MSLs) are gaining attention for various applications, from biophysical cell models to molecular robots. Despite their growing importance, reviews on MSLs across disciplines are scarce. This review fills the gap by providing a systematic overview of MSL design, from applications to functionalization and to formation, aimed at
