INTRODUCTION Ventral hernias are common surgical problems in the geriatric population. Although ventral hernias are electively repaired in younger patients, the safety and efficacy of elective laparoscopic hernia repair in the geriatric age group is not well documented in the literature. METHODS A review of 155 patients undergoing laparoscopic ventral(More)
A key feature of Parkinson's disease is the dopaminergic neuronal cell loss in the substantia nigra pars compacta. Besides inflammation, oxidative stress and apoptosis, a recent hypothesis suggested that degeneration of dopaminergic neurons occurs secondary to abnormal mitosis in these 'postmitotic neurons', ending up in apoptosis. Hence, recent therapies(More)
Parkinson's disease (PD) is primarily a motor disorder that involves the gradual loss of motor function. Symptoms are observed initially in the extremities, such as hands and arms, while advanced stages of the disease can effect blinking, swallowing, speaking, and breathing. PD is a neurodegenerative disease, with dopaminergic neuronal loss occurring in the(More)
Developmental neurotoxicity (DNT) refers to the toxic effects induced by various chemicals on brain during the early childhood period. As human brains are vulnerable during this period, various chemicals would have significant effects on brains during early childhood. Some toxicants have been confirmed to induce developmental toxic effects on CNS; however,(More)
BACKGROUND Organophosphates (OPs) represent the most widely used class of pesticides. Although perceived as low toxicity compounds compared to the previous organochlorines, they still possess neurotoxic effects both on acute and delayed levels. Delayed neurotoxic effects of OPs include OPIDN and OPICN. The mechanisms of these delayed effects have not been(More)
A key feature of Parkinson's disease is the dopaminergic neuronal cell loss in the substantia nigra pars compacta. Many triggering pathways have been incriminated in the pathogenesis of this disease including inflammation, oxidative stress, excitotoxicity and apoptosis. Thyroid hormone is an essential agent for the growth and maturation of neurons;(More)
