Biochemical Alterations and Motor Dysfunctions in Corpus Striatum of Rats Brain Exposed to Azo Dyes.

Azo food dyes are prohibited in most countries, but their injudicious use is still reported particularly in the developing Nations. Continuous use of contaminated food raises health concerns and given this the present study designed to investigate the effects of 3 non-permitted azo dyes (metanil yellow - MY, malachite green - MG, and sudan III - SIII) on neurobehavioral, neurochemicals, mitochondrial dysfunction, oxidative stress, and histopathological changes in the corpus striatum of rats. Rats were grouped and treated with MY (430 mg/kg), MG (13.

Evaluating the effectiveness of different household washing techniques for removal of insecticides from spinach and chickpea leaves by micellar liquid chromatography.

In the past few decades, the employment of green analytical approaches in chromatographic method development has attracted the analytical separation community. The greenness of the developed method depends upon the toxicity of solvents and the amount of generated post-analysis waste generated. In this concern, micellar liquid chromatography (MLC) is a simple and rapid technique that generates very low toxic waste compared to traditional chromatographic pesticide detection methods.

Azo food dye neurotoxicity in rats: A neurobehavioral, biochemical, and histopathological study.

We have investigated the effects of the AFDs metanil yellow (MY), malachite green (MG), and sudan III (SIII) on cognitive impairment, oxidative stress, mitochondrial dysfunction, neuro-enzyme activities, and histopathology in rats. Rats treated with MY (430 mg/kg), MG (13.

Micellar enhanced chromatographic separation of selected hazardous chemical present in hair dye and their detection in formulations and swab, including assessment of damage caused to cuticle of hair shaft.

Hydroquinone (HQ), resorcinol (RS), m-aminophenol (m-AMP) and p-phenylenediamine (p-PPD) are aromatic compounds which are generally used in hair dyes to provide different colours to hair. In European Union the concentrations of HQ, RS, m-AMP and p-PPD is regulated in hair dyes and other cosmetic products by EU commission regulation EU/2019/831. This legislation is generally exercised because all these compounds are toxic and may cause severe allergies when used regularly.

Direct injection green chromatographic method for simultaneous quantification of amoxicillin and amikacin in maternity hospital wastewater (Sagar, India).

Amoxicillin (AMO) and amikacin (AMK) are broad-spectrum antibiotics that are most preferably given post-delivery (normal and cesarian) in the maternity hospitals located in Sagar city (Madhya Pradesh), India. Both the antibiotics make their way through sewage/drainage systems into the environment in the form of metabolized and unmetabolized compounds. Growing concern about the contamination of wastewater by antibiotics requires fast, sensitive and eco-friendly techniques.

Non-permitted food colorants induced neurotoxicity in cerebellum of rat brain.

Food colorants are important food additives that not only enhance the appearance of food but also appetite. These can be obtained from natural and synthetic sources, but synthetic sources are more popular, efficient, and potential. Non-permitted food colorants (NPFCs) are banned, but their injudicious use in developing countries associated with various adverse health effects.

Optimization and Validation of a Chromatographic Method for the Quantification of Isoniazid in Urine of Tuberculosis Patients According to the European Medicines Agency Guideline.

Isoniazid is a drug that is widely used against tuberculosis. However, it shows high interpatient variability in metabolism kinetics and clinical effect, which complicates the prescription of the medication and jeopardizes the success of the therapy. Therefore, in a specific patient, the pharmacokinetics of the drug must be elucidated to decide the proper dosage and intake frequency to make the drug suitable for therapeutic drug monitoring.

Determination of adulteration of malachite green in green pea and some prepared foodstuffs by micellar liquid chromatography.

A simple, fast, and robust micellar LC method was developed for the separation and identification of the nonpermitted color malachite green in green pea and some ready-to-eat foodstuffs. Malachite green (4-[(4-dimethylaminophenyl) phenyl-methyl]-N,N-dimethylaniline) is a hazardous dye that is used to treat fungal and protozoan infections in fish and is a common adulterant (coloring agent) in green pea and other green vegetables because of its green color. In the present work, malachite green was determined in various foodstuffs using a direct injection technique on an RP C18 column with isocratic elution.
