superoxide dismutase/atrophy

Nitric oxide (NO) synthase (NOS)-containing cerebrocortical neurons degenerate in patients with amyotrophic lateral sclerosis (ALS) and dementia, and in transgenic mice expressing a mutated superoxide dismutase gene (G93A) associated with familial ALS. The cerebral cortex of transgenic mice

We performed a comparative neuropathological study on two siblings with familial amyotrophic lateral sclerosis (FALS). The clinical course of the sister who died at age 46 was 18 months, and that of the brother who died at age 65, 11 years. The neuropathological findings of the female were

We investigated motoneuron degeneration after proximal nerve injury in presymptomatic transgenic (tg) rats expressing human mutant Cu/Zn superoxide dismutase (SOD1). The right facial nerves of presymptomatic tg rats expressing human H46R or G93A SOD1 and their non-tg littermates were avulsed, and

Magnetic resonance imaging (MRI) is becoming the preferred neuroimaging modality for the diagnosis of human amyotrophic lateral sclerosis (ALS). A useful animal model of ALS is the superoxide dismutase 1G93A G1H transgenic mouse, which shows many of the clinico-pathological features of the human

We previously showed that some antipurinergic receptor P2X4 antibodies cross react with misfolded forms of amyotrophic lateral sclerosis (ALS)-linked mutant Cu/Zn superoxide dismutase (SOD1). Cross reactivity might be caused by abnormal exposure of an epitope in the inner hydrophobic region of SOD1

OBJECTIVE To elucidate whether any polymorphic genes for xenobiotic-metabolizing and antioxidant enzymes are associated with the development of exudative age-related macular degeneration. METHODS A hospital-based case-control study was performed on a consecutive series of 102 Japanese patients with

Spinal muscular atrophy (SMA) and amyotrophic lateral sclerosis (ALS) are among the most common motor neuron diseases to afflict the human population. A deficiency of the survival of motor neuron (SMN) protein causes SMA and is also reported to be an exacerbating factor in the development of ALS.

BACKGROUND Oxidative stress is involved in the pathogenesis of many chronic disorders including cancer, inflammation, and neurologic diseases. Reactive oxygen species (ROS) may play a major role in age-related macular degeneration (AMD). This study investigated the mRNA and protein profiles of

Lipid peroxidation (LP) and superoxide dismutase (SOD) activity were determined in erythrocytes and skeletal muscle obtained from patients with limb-girdle and facioscapulohumeral muscular dystrophies, neurogenic atrophies and from age-matched control subjects. Neither lipid peroxidation nor SOD

Amyotrophic lateral sclerosis (ALS) is a devastating neurologic disease that rapidly progresses from mild motor symptoms to severe motor paralysis and premature death. Until recently, there were few substantive studies conducted on the pathogenesis of the disease. With the genetic linkage of

The efficacy of 4-hydroxy-2,2,6,6-tetramethylpiperidine-l-oxyl (TEMPOL), a metal independent superoxide dismutase (SOD) mimic, in ameliorating light-induced retinal degeneration was investigated. Thirty-six Lewis albino rats were exposed to green fluorescent light (490-580 nm, 160-180 foot-candles)

Primary dopaminergic neuronal cultures with increased superoxide dismutase (SOD) activity were established for studying the role of superoxide anion (O2-) in 1-methyl-4-phenylpyridinium (MPP+)-induced degeneration of dopamine (DA) neurons. Mean SOD activity in cultures prepared from transgenic

Amyotrophic lateral sclerosis (ALS) is a neurodegenerative disease involving motor neuron degeneration, occurring in sporadic and familial forms. Mutations in Cu/Zn superoxide dismutase gene (SOD-1) play a key role in the pathogenesis of the familial form in which it is present in about 20%. The

OBJECTIVE The aim of this study was to investigate superoxide dismutase (SOD) activity together with malondialdehyde (MDA) levels in a group of Chinese patients with age-related macular degeneration (AMD). METHODS Serum SOD activity and MDA levels were analysed in 56 AMD patients with subtypes
