Diversity of Pharmaceuticals Enhances Antibiotic Resistance in the Invertebrate Gut via Biofilm‐Mediated Mechanisms

Advanced Science, EarlyView.
Pharmaceutical diversity acts as an independent driver of antibiotic resistance in soil invertebrates. While bulk soil remains unaffected, the collembolan gut microbiome exhibits significant resistance gene enrichment under complex chemical exposure and diurnal warming.

Mitochondria and Neuromast Tagging With Fluorescent Gallium‐Triapine Analogues: In Cellulo MP FLIM and Zebrafish Live Imaging

Advanced Science, EarlyView.
Fluorescent BODIPY‐conjugated thiosemicarbazone ligands and their Ga(III), In(III), and Fe(III) complexes, inspired by Triapine, are developed as theranostic agents. Multiphoton FLIM and confocal microscopy in cancer cells and zebrafish reveal real‐time uptake, mitochondrial localisation, and whilst spectroscopic assays indicated preserved complex ...

DEVELOPMENT OF DIAMOND DRILLING BIT FOR DIRECTIONAL DRILLING

Известия Томского политехнического университета: Инжиниринг георесурсов, 2022
The relevance. Many years of experience in directional drilling has made it possible to identify complex mining and geological conditions in which the use of deflectors leads to decrease in the effectiveness of the curvature and accidents. So, for example, the fastening of continuous deflectors in hard, very hard and abrasive rocks, when the borehole ...
