Although the effects of acute pesticide poisoning are well known but, hardly any data exists regarding the health effects after long-term low-level exposure. Major unresolved issues include the effect of moderate exposure in the absence of poisoning. The present study elucidates a possible mechanism by which chronic organophosphate exposure (dichlorvos 6(More)
Numerous epidemiological studies have shown an association between pesticide exposure and the increased risk of developing Parkinson's disease. Previously we have reported that Dichlorvos exposure can induce oxidative stress, resulting in over-expression of pro-apoptotic genes and finally caspase-dependent nigrostriatal dopaminergic neuronal cell death in(More)
In this study, we investigated the protective effect of chronic quercetin (a natural flavanoid) administration against Al-induced cognitive impairments, oxidative damage, and cholinergic dysfunction in male Wistar rats. Al lactate (10 mg/kg b.wt./day) was administered intragastrically to rats which were pre-treated with quercetin (10 mg/kg b.wt./day,(More)
OBJECTIVE Paraoxonase-1 (PON1), an HDL-C associated enzyme, protects lipoproteins from oxidation. There is evidence that PON1 enzyme activity is reduced in the patients with type 2 diabetes mellitus (T2DM). North-West Indian Punjabis, a distinct ethnic group has high incidence of T2DM. However till date there is no information regarding PON1 enzyme(More)
The present investigation was carried out to elucidate a possible molecular mechanism related to the effects of aluminium-induced oxidative stress on various mitochondrial respiratory complex subunits with special emphasis on the role of Peroxisome proliferator activated receptor gamma co-activator 1α (PGC-1α) and its downstream targets i.e. Nuclear(More)
Aluminum is a light weight and toxic metal present ubiquitously on earth, which has gained considerable attention due to its neurotoxic effects. It also has been linked ecologically and epidemiologically to several neurological disorders, including Alzheimer's disease (AD), Parkinson's disease (PD), Guamanian-Parkinsonian complex and Amyotrophic lateral(More)
The present study was designed with an aim to analyze the effect of acute aluminium phosphide (ALP) exposure (10mg/kg b.wt, intragastrically) on the kinetic characteristics of cytochrome oxidase and energy metabolism in male Wistar rat liver mitochondria. Liver mitochondrial preparations from ALP-treated rats exhibited significant decrease (66%) in the(More)
Oxidative stress has for long been linked to the neuronal cell death in many neurodegenerative conditions. Conventional antioxidant therapies have been less effective in preventing neuronal damage caused by oxidative stress due to their inability to cross the blood brain barrier. Nanoparticle antioxidants constitute a new wave of antioxidant therapies for(More)
Aluminum phosphide (AlP), a widely used fumigant and rodenticide leads to high mortality if ingested. Its toxicity is due to phosphine liberated when it comes in contact with moisture. The exact mechanism of action of phosphine is not known. In this study male Wistar rats were used. The animals received a single dose (20mg AlP/kg body weight i.g.) orally.(More)
Dichlorvos [2,2-dichlorovinyl dimethyl phosphate] is one of the most common in-use organophosphate (OP) in developing nations. Previous studies from our lab have shown chronic Dichlorvos exposure leads to neuronal cell death in rats. However, the extent of damage caused by Dichlorvos to other cells of the central nervous system (CNS) is still not clear.(More)
