Efflux-Mediated Resistance in Enterobacteriaceae: Recent Advances and Ongoing Challenges to Inhibit Bacterial Efflux Pumps

Antibiotics
Efflux is one of the key mechanisms used by Gram-negative bacteria to reduce internal antibiotic concentrations. These active transport systems recognize and expel a wide range of toxic molecules, including antibiotics, thereby contributing to reduced ...

Influence of seeding rates on the quantum yield of photosynthesis for some field crops

Труды по прикладной ботанике, генетике и селекции
Background. Photosynthesis is one of the most important physiological processes in plants, affecting the productivity of agrocenoses. Creating conditions for crops to absorb and convert solar energy as effectively as possible can be a means of increasing

ELF5‐Mediated Enhancer–Promoter Interaction Regulates LALBA Expression in Ovine Mammary Gland

Advanced Science, EarlyView.
In the study, we systematically investigate the epigenetic mechanisms underlying lactation traits in sheep by integrating transcriptomic, chromatin accessibility, histone modification, and functional analyses. We identify a super‐enhancer at the LALBA locus and demonstrate that enhancer E4 functions as its core regulatory element.

Multiple mechanisms contribute to fluorometry signals from the voltage-gated proton channel

Communications Biology, 2022
Fluorometry signals indicating conformational change in an ion channel are generated by quenching amino acids and lipid effects during movement of the dye relative to the plane of the membrane.

Critical evaluation of heat extraction temperature on soluble microbial products (SMP) and extracellular polymeric substances (EPS) quantification in wastewater processes

Water Science and Technology, 2022
While soluble microbial products (SMP) and extracellular polymeric substances (EPS) in wastewater bioprocesses have been widely studied, a lack of standard quantification procedures make it difficult to compare results between studies.

A Living Multi‐Omics PDX Biobank of High‐Risk Sarcomas Reveals ecDNA‐Driven Oncogene Amplification in Osteosarcoma and Enables Preclinical Precision Oncology

Advanced Science, EarlyView.
A living multi‐omics sarcoma PDX biobank is enriched for high‐risk disease and preserves key patient tumor features at histopathological and molecular levels. Integrated profiling reveals ecDNA‐driven oncogene amplification in osteosarcoma and preferential retention of ecDNA during PDX evolution.

Determination of Extra Virgin Olive Oil Adulteration Using Laser Induced Fluorometry – Chlorophyll Relative Intensity Method

Acta Technologica Agriculturae
A new method has been proposed for detecting the potential adulteration of extra virgin olive oil with processed sunflower oil. This method is based on analysing the laser-induced fluorescence (LIF) spectra of samples.

The Histidine 382 Residue Influences the Thermal Stability and Binding Propensity of the E2 Domain of Amyloid Precursor Protein

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT The E2 domain of amyloid precursor protein (APP_E2) plays a central role in the protein's function. We reinvestigate how the missense mutation, ΔH382L, affects the domain's thermal stability and ligand binding propensity through differential scanning fluorometry.
