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)
Recent global events have focused attention on the potential threat of international and domestic chemical terrorism, as well as the possibility of chemical warfare proliferation. Sulphur mustard (SM) is one of the potent chemical warfare agents (CWA), which initiates a cascade of events that converge on the redox mechanisms common to brain injury. The(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)
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)
Till date, an exact causative pathway responsible for neurodegeneration in Huntington’s disease (HD) remains elusive; however, mitochondrial dysfunction appears to play an important role in HD pathogenesis. Therefore, strategies to attenuate mitochondrial impairments could provide a potential therapeutic intervention. In the present study, we used curcumin(More)
The present study was designed to analyze the effect of acute aluminium phosphide (ALP) (10 mg/kg body wt.) exposure on the glucose homeostasis in rat liver and brain. ALP has been implicated in the inhibition of cytochrome oxidase causing reduced oxygen uptake and decreased ATP synthesis eventually resulting in cellular energy crisis. A significant(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 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)
Microglia play an important role in synaptic pruning and controlled phagocytosis of neuronal cells during developmental stages. However, the mechanisms that regulate these functions are not completely understood. The present study was designed to investigate the role of purinergic signalling in microglial migration and phagocytic activity during post-natal(More)
