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.

Article Synopsis
  • Azo Food Dyes (AFDs) like metanil yellow, malachite green, and sudan III may negatively impact health, leading to cognitive impairments in rats after 60 days of exposure.
  • Significant biochemical changes were noted in the brain regions associated with learning and memory, including increased lipid peroxidation and altered enzyme activities.
  • Histological analysis showed neuronal damage, which corresponded with the observed cognitive deficits and biochemical changes.

The environment is varying day by day with the introduction of chemicals such as pesticides, most of which have not been effectively studied for their influence on a susceptible group of population involving infants and pregnant females. Rotenone is an organic pesticide used to prepare Parkinson's disease models. A lot of literature is available on the toxicity of rotenone on the adult brain, but to the best of our knowledge, effect of rotenone on prenatally exposed mice has never been investigated yet.

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.

Chronic exposure to arsenic through drinking water and occupational exposure has been found to be associated with the diabetic symptoms. Earlier, we reported that arsenic induced enhanced oxidative stress, inflammation, dislipidemia and hepatotoxicity in mice have been protected by treatment with (amla). The present study has therefore been focused to investigate the efficacy of amla in mitigation of arsenic induced hyperglycemia in mice.

The present study investigated the protective effect of curcumin and mitochondrial-targeted curcumin (MTC) in rotenone-induced cerebellar toxicity in mice. Treatment of rotenone in mice significantly shortened the stride length for both forelimb and hind-limb and increased fore-paws and hind-limb base width. Co-treatment of curcumin and MTC with rotenone improved the walking pattern.

The present study investigated the pesticide induced adverse health effects, hematological and biochemical alterations among agriculture workers. A cross sectional study of 51 agriculture workers and 54 unexposed subjects was carried out to evaluate hematological and biochemical alterations in blood. Pesticide exposed individuals were reported adverse clinical outcomes, including tingling, muscle pain, headache, skin disease, etc.

Background: Mitochondrial impairments due to free radicals are implicated in a wide range of neurotoxicological alterations. Curcumin, an active ingredient of turmeric has shown protective efficacy against oxidative damage due to its strong antioxidant potential, but its efficiency is restricted due to low bioavailability in the mitochondria. In view of this, we have synthesized mitochondria-targeted curcumin (MTC) with an aim to investigate its efficacy against rotenone-induced oxidative damage in mice and isolated mitochondria.

The problem of pesticides is not new and its exposure to human due to indiscriminate use is largely associated with the health related problems including neurotoxicological alterations. High levels of pesticide residues and their metabolites in the dietary constituents, food materials, maternal blood, cord blood, placenta breast milk have been reported and linked to alterations in birth weight, crown heel length, head circumference, mid-arm circumference and ponderal index of the neonates. Epidemiological studies have suggested that exposure of pesticide to human could be a significant risk factor for neurological disorders, including Parkinson's disease, Alzheimer's disease and multiple sclerosis.

Background: Lead is widely distributed in the environment and has been found to be associated with various health problems including neurodegenerative diseases.

Purpose: In view of the increasing health risk caused by lead, this study has been carried out to investigate the neuroprotective effect of omega-3 fatty acid (omega-3FA) in lead-induced neurotoxicity in rats.

Methods: Biochemical parameters including oxidative stress in brain regions, lead levels in blood and brain regions and histopathological examination of brain regions of rats were carried out in the present study.

In view of the increasing risk of lead on human health, the present study has been carried out to investigate the neuroprotective effect of omega-3 fatty acid on chronic lead-induced neurotoxicity and behavioral impairment in rats. Different neurobehavioral parameters, biochemical assays, and histopathological analyses in brain regions of rats were conducted. Rats exposed to different doses of lead (lead acetate 2.

Neurodegenerative disorders represent clusters of serious diseases that results in progressive deterioration of normal structure and physiology of central nervous system. Pathophysiology of Alzheimer's, Parkinson's or other neurodegenerative disorders involves multifaceted permutation of genetic and environmental factors. Combinations of lifestyle modification linked with environmental factor jointly or alone represent the largest share of cases of these disorders.

Exposure to arsenic in individuals has been found to be associated with immune related problems. In earlier studies, we have demonstrated that amla protects against arsenic induced oxidative stress and apoptosis in thymus and spleen of mice. In continuation to that the present study has therefore been focused to investigate the protective efficacy of amla in arsenic induced inflammation and immunotoxicity in mice.

Introduction: Arsenic, an environmental contaminant naturally occurred in groundwater and has been found to be associated with immune-related health problems in humans.

Objective: In view of increasing risk of arsenic exposure due to occupational and non-occupational settings, the present study has been focused to investigate the protective efficacy of amla against arsenic-induced spleenomegaly in mice.

Results: Arsenic exposures (3 mg/kg body weight p.

Various types of lipids and their metabolic products associated with the biological membrane play a crucial role in signal transduction, modulation, and activation of receptors and as precursors of bioactive lipid mediators. Dysfunction in the lipid homeostasis in the brain could be a risk factor for the many types of neurodegenerative disorders, including Alzheimer's disease, Huntington's disease, Parkinson's disease, and amyotrophic lateral sclerosis. These neurodegenerative disorders are marked by extensive neuronal apoptosis, gliosis, and alteration in the differentiation, proliferation, and development of neurons.
