Innovative Potentiometric Quantification of Flutamide Using Novel Ion-Selective Electrodes with Sulfonphthalein Dyes
Chikkalingaiah Siddaraju, Nagaraju Rajendraprasad

For the first time, two simple, selective, and inexpensive sensors were developed and validated to quantify flutamide in drug formulations and extended to analyze drug-infused human urine samples. These sensors showed a good linear response over a wide pH range. The analytical methods developed showed excellent selectivity, reliability, and robustness. The eco-friendly developed methods are suitable for routine analytical applications in quality control laboratories, as they do not require sophisticated equipment or highly skilled operators.

An Ecofriendly Potentiometric Technique to Measure the Iodine Values of Animal Fats
Nandhini Dhanavel, Meenakshi Halada Nandakrishnan

The aim of this work was to determine and compare the iodine number of various animal fats using the Wijs method and a proposed green method. The iodine values obtained were statistically analyzed using the Student t-test and the Snedecor F-test. The GAPI and AGREE metrics were used to evaluate the environmental impact of the iodine determination methods used. The proposed green potentiometric analysis method was more environmentally friendly than the traditional Wijs method. In terms of cost of chemicals and safety in the toxic base, the proposed green method was quite favorable.

qPCR Analysis of DNA Extracted from Adulterated Personal Care Products Using a Modified CTAB-based DNA Extraction Method
Siti Sarah Abu Bakar, Azmaniza Tulimin, Norhaniza Aminuddin, Nor Kartini Abu Bakar

In this work, the cetyltrimethylammonium bromide (CTAB) method used for DNA extraction was modified to ensure successful detection and authentication of target species in personal care products. The developed method was then applied to real samples of personal care products adulterated with porcine for halal authentication analysis by qPCR. The developed method was compared with the commercial DNA extraction kits available in the market for cosmetic products. The robustness of the modified CTAB method was evaluated by comparing the DNA purity and yield across different samples. This modified CTAB method can serve as an effective in-house method for species authentication in common personal care products.

Chemical Composition Analysis of Human Gallstones in Beni Mellal-Khenifra, Morocco
Mohamed Bouha, Malika Echajia, Latifa Amini, Mohamed Mbarki, Najat Elhadiri, Mustapha Oubenali, Mohamed Berkani

Techniques such as scanning electron microscopy, Fourier transform infrared spectroscopy and X-ray diffraction were used to analyze gallstone samples from a total of 226 patients.
This comprehensive approach identified the presence of a variety of chemical components in gallstones, including cholesterol, bilirubin, calcium carbonate, and calcium phosphate.
Fourier transform infrared spectroscopy was favored for compositional analysis because of its accuracy, sensitivity, and minimal sample preparation requirements.

This study provided important insights into the pathogenesis of gallstones in Morocco. By understanding the chemical composition of gallstones in this population, it is possible to better understand the factors that contribute to their formation and development. This information can be used to develop more targeted prevention and treatment strategies.
