Mechanistic model advancements for optimal calcium removal in water treatment: Integral operation improvements and reactor design strategies.

Drinking water softening has primarily prioritized public health, environmental benefits, social costs and enhanced client comfort. Annually, over 35 billion cubic meters of water is softened worldwide, often utilizing three main techniques: nanofiltration, ion exchange and seeded crystallization by pellet softening. However, recent modifications in pellet softening, including changes in seeding materials and acid conditioning used post-softening, have not fully achieved desired flexibility and optimization.

Synthesis and Pharmacological Characterization of Fluorescent Ligands Targeting the Angiotensin II Receptors Derived from Agonists, β-Arrestin-Biased Agonists, and Antagonists.

Angiotensin II (AngII) regulates cerebral circulation and binds with a similar affinity to AT and AT receptors. Biased AT agonists, such as TRV027, which are able to selectively activate β-arrestin while blocking the G pathway, appear promising as new therapeutics. New pharmacological tools are needed to further explore the impact of biased AT agonists on cells or tissues, such as the cerebral vessels.

Antibiofilm approaches as a new paradigm for treating infections.

The lack of effective antibiotics for drug-resistant infections has led the World Health Organization to declare antibiotic resistance a global priority. Most bacterial infections are caused by microbes growing in structured communities called biofilms. Bacteria growing in biofilms are less susceptible to antibiotics than their planktonic counterparts.

Biosourced Au(III) Complexes from D-Xylose: Synthesis and Biological Evaluation.

A series of xylose-based ligands was obtained using a convenient approach, in a few steps from D-xylose. The complexation properties of these ligands towards Au cations have been studied through different methods (multinuclear NMR, mass spectrometry, elemental analysis). The biological properties (antibacterial and anti-tumoral) of all the isolated xyloside Au(III) complexes were investigated in vitro.
