Alzheimer's disease is multi-component neurodegenerative disorder. Oxidative stress disrupts regular functioning of metabolism in early-onset disease. It causes Tau phosphorylation, formation neurofibrillary tangle and neuron reduction. Due to intense binding phosphorylated amino acids aluminum, it induces self-assembly deposition high degree cytoskeletal proteins, such as microtubule neurofila...

Objective(s): According to recent studies, valproate shows some protection against oxidative stress (OS) induced by neurotoxins. Current investigation tried to determine the possible ameliorating effects of sodium valproate (SV) against aluminum (Al)-induced cell death, apoptosis, mitochondrial membrane potential (MMP), and OS in PC12 cells.Materials ...

Gallium is a trivalent semi-metallic element that has shown antimicrobial activity against several important human pathogens. This antimicrobial activity is likely related to its substitution in important iron-dependent pathways of bacteria. The genus Staphylococcus, which includes human and animal pathogens that cause significant morbidity and mortality, requires iron for growth and colonizati...

Background: Aluminum (Al) exposure is among the environmental risk factors that may involve in the pathogenesis of neurodegenerative diseases. Oxidative stress has a critical role in the Al-induced toxicity. Saffron is a plant with potent radical scavenging and anti-oxidative properties. This investigation was designed to evaluate the possible protective effects of saffron extract (SE) on alumi...

Two oxidovanadium(V) complexes, [VOL1L] (1) and [VOL2L] (2) (L = ethyl maltolate), derived from the aroylhydrazones 4-bromo-N’-(2-hydroxy-5-methylbenzylidene)benzohydrazide (H2L1) N’-(3,5-dibromo-2-hydroxybenzylidene)- 4-methoxybenzohydrazide (H2L2), respectively, have been synthesized characterized by elemental analysis, infrared electronic spectroscopy. Structures of complexes were further co...

Recently, aluminium (Al) has been proposed to be one of the environmental factors responsible for cause Alzheimer's disease (AD). However, the relationship between Al and AD is controversial. To investigate the effects of subchronic Aluminium-maltolate (Al (mal)(3)) exposure on the behavioral, electrophysiological functions. Forty Sprague-Dawley (SD) rats were randomly distributed into five gro...

Aluminum maltolate (Al-malt) causes neurodegeneration following in vivo exposure, and apoptosis plays a prominent role. The objective of this study was to define the form of cell death induced by Al-malt and to establish an in vitro model system amenable to mechanistic investigations of Al-malt-induced cell death. Neuro-2a cells, a murine neuroblastoma cell line, were treated with Al-malt for 2...

Development of lanthanide detoxification agents and protocols is of great importance in management of overdoses. Due to safety of maltol as a detoxifying agent in metal overloads, it can be used as a lanthanide detoxifying agent. In order to demonstrate the biodistribution of final complex, [(153)Sm]-samarium maltolate was prepared using Sm-153 chloride (radiochemical purity >99.9%; ITLC and sp...

Exposure to high levels of aluminium (Al) leads to neurofibrillary degeneration and that Al concentration is increased in degenerating neurons in Alzheimer's disease (AD). Nevertheless, the role of Al in AD remains controversial and there is little proof directly interlinking Al to AD. The major problem in understanding Al toxicity is the complex Al speciation chemistry in biological systems. A...

OBJECTIVES The role of aluminum (Al) in the pathogenesis of neurodegenerative diseases has been implicated in several studies. However, the exact mechanisms of cytotoxic effects of Al have not been elucidated yet. The aim of this study was to investigate the effect of L-type calcium channel antagonist, nimodipine (NM), and lithium chloride (LiCl) on Al-induced toxicity in PC12 cells. MATERIAL...
