Turbidimetry of Two Aqueous Phase Emulsions and Related Systems

, 1992
Emulsion stability was studied using turbidimetry. the emulsions of interest contained one or more polymers. the first system studied was the two aqueous phase system made of a single solvent (water) and two polymers (polyethylene glycol and dextran). in

Inflammation‐driven variability in drug metabolism: Insights from voriconazole treatment of HSCT recipients

British Journal of Clinical Pharmacology, Volume 92, Issue 7, Page 2250-2259, July 2026.
Aims Voriconazole is commonly used to prevent fungal infections after haematopoietic stem cell transplantation (HSCT). Although its metabolism is influenced by CYP2C19 genetics and inflammation, their combined effect is rarely considered in clinical practice, and integrated analyses remain limited.

Determinação de heparina fracionada em preparações farmacêuticas utilizando turbidimetria

Química Nova, 2011
A turbidimetric method has been used for quantification of fractionated heparin (FH) in pharmaceutical dosage. The UV detection at two wavelengths (290 and 500 nm) showed a significant increase in sensitivity of the method, specificity, and linearity to ...

Kinetics of the early stage of dispersion polymerization in supercritical CO2 as monitored by turbidimetry. 2. Particle formation and locus of polymerization

, 2022
S.3653-3661We present a study of dispersion polymerization of methyl methacrylate in supercritical CO2 (sc-CO2) at 330 bar in situ by turbidimetry. All experiments have been done in the presence of the macromonomer poly(dimethylsiloxane)-monomethacrylate

Be Aware of Aggregators in the Search for Potential Human ecto-5′-Nucleotidase Inhibitors

Molecules, 2018
Promiscuous inhibition due to aggregate formation has been recognized as a major concern in drug discovery campaigns. Here, we report some aggregators identified in a virtual screening (VS) protocol to search for inhibitors of human ecto-5&prime ...

Homogeneous Nucleation of Hydroxyapatite, Ca₅OH(PO₄)₃, at 37 °C

Crystals, 2020
Precipitation of the calcium phosphate hydroxyapatite, Ca5OH(PO4)3, is studied by simple mixing of reagent solutions and measurement of light scattering (turbidimetry) at six different wavelengths from 300 to 800 nm.

Impact of FCGR2A and FCGR3A Gene Variants on the Response to Rituximab in Patients With Glomerular Diseases

Pharmacology Research &Perspectives, Volume 14, Issue 3, June 2026.
ABSTRACT Rituximab is an anti‐CD20 monoclonal antibody used in autoimmune diseases, including glomerular diseases. The FCGR2A (rs1801274) and FCGR3A (rs396991) variants have been suggested to affect rituximab efficacy; this study evaluates their impact on rituximab efficacy in glomerular diseases.

Anticipating cosmetic emulsion stability using a novel multi‐analytical approach

International Journal of Cosmetic Science, Volume 48, Issue 3, Page 589-599, June 2026.
A novel combination of granulometry, turbidimetry and rheology enables early detection of cosmetic emulsion instability—reducing assessment time from 30 to 8 days. This rapid method distinguishes stable from unstable emulsions under identical conditions, offering a powerful tool for formulation screening and industrial quality control.
