background: cells have complex network of antioxidant enzymes that protect cells from induced damages by reactive oxygen species (ros). catalase and superoxide dismutase are known for their role as primary protection against oxidative stress. oxidative damage is an important risk factor in age-related macular degeneration disease (amd). for the first time in this study the impact of genetic pol...

Methamphetamine (meth) is a neurotoxic psychostimulant that increases monoamine oxidase (MAO)-dependent mitochondrial oxidant stress in axonal but not somatic compartments of substantia nigra pars compacta (SNc) and locus coeruleus (LC) neurons. Chronic meth administration results the degeneration SNc LC neurons male mice, MAO inhibition neuroprotective, suggesting deleterious effects chronic b...

In this paper, we consider a class of degenerate elliptic equations with arbitrary power degeneration. The issues about the existence, uniqueness, and smoothness solutions semiperiodic Dirichlet problem for degeneration are studied. two-sided estimates singular numbers (s-numbers) obtained. Note that show rate approximation found by finite-dimensional subspaces. Here, also obtain eigenvalues. W...

ABSTRACT It is necessary to use virus-free garlic seeds reach high bulb yields; however, information needed on the number of generations that these can be grown in field conditions without decreasing yield and quality due degeneration. Degeneration dependent production season locality; thus, objective this work was evaluate degeneration cultivars Semiarid region Northeast Brazil, through three ...

Four subtypes of frontotemporal lobar degeneration with TDP-43 immunoreactive inclusions have been described (types A-D). Of these four subtypes, motor neuron disease is more commonly associated with type B pathology, but has also been reported with type A pathology. We have noted, however, the unusual occurrence of cases of type C pathology having corticospinal tract degeneration. We aimed to ...

the pathology of spinal cord injury (sci) comprises multiple processes characterized by extensive cell death and glial scar formation, which together limits axonal regeneration. in particular, variations in chronic demyelination of the lesion have been found to be largely independent of injury intensity, suggesting a secondary pathologic origin. this chronic demyelination results in progressive...
