The reproducibility of the ferron method for aluminium has been greatly improved by the addition of cetyltrimethylammonium chloride (CTMAC). The improvement is attributed to reduction of the reagent blank and increased stability of Al(ferron)(3-)(3). The aluminium-ferron complex formed in the presence of CTMAC has an absorption peak at 385 nm. The interference from iron can be eliminated by application of a correction based on measurement at two wavelengths.

Flavonoids are a group of specialized metabolites that are ubiquitously found within the plant kingdom. While they fulfill various important functions within the plant, they are also utilized by humans in a variety of different fields such as medicine, food science, and agriculture. Thus, to elucidate the chemical composition of any given plant extract, extraction and identification of flavonoids are of high interest.

For paediatric patients suffering from neurofibromatosis, Selumetinib (SEL) is the only approved drug. Here an original ecofriendly and high pace method is introduced using 96- microwell spectrophotometric assay (MW-SPA) to measure SEL content in bulk and commercial pharmaceutical formulation (Koselugo capsules). This assay was relied on in-microwell formation of a coloured charge transfer complex (CTC) upon interaction of SEL with 2,3-dichloro-5,6-dicyano-1,4-benzoquinone (DDQ).

Objective: Bladder tissue models have been developed using smooth muscle cells (SMCs) on various scaffolds to mimic bladder morphology and physiology. This study investigates the effects of co-culturing fetal and adult SMCs on growth properties and protein profiles to understand cellular interactions and population kinetics.
Methods: Bladder tissue samples from 10 adult and 10 fetal New Zealand rabbits were divided into 5 groups: adult SMCs (A), fetal SMCs (F), 50%A+50%F (A+F), 75%A+25%F (3A+F), and 25%A+75%F (A+3F).
