cytochrome oxidase/atrophy

We previously demonstrated markedly inhibited brain mitochondrial respiration only in cats that (a) were hyperglycemic at anoxia and (b) had neurologic signs, i.e., fasciculations in tongue or facial muscles or focal seizures following reoxygenation. However, since the relationship between time of

In order to investigate the levels of cytochrome oxidase activity in neuronal mitochondria in the brain of the brindled mouse hemizygote (BM), the cerebella and brain stems from 12 pairs of brindled and normal littermates aged 13-16 days were examined. The diaminobenzidine method for light- and

The human extrastriate occipital cortex contains several visual areas that are probably analogues of macaque areas V2, V3, VP, V4 and V5. Tracing of callosal connections has led to the anatomical identification of these areas and to the characterization of some of them by cyto- and myeloarchitecture

A previously healthy and normally developed 17-year-old young female presented with a sudden onset of focal motor seizure status that proved to be refractory to anticonvulsive treatment. Severe encephalopathy with visual impairment leading to blindness, mental deterioration, and predominantly left

Resveratrol has recently been used as a supplemental treatment for several neurological and nonneurological diseases. It is not known whether resveratrol has neuroprotective effect on amyotrophic lateral sclerosis (ALS). To assess the effect of resveratrol on the disease, we tested this agent on an

We examined young adult and late middle-aged male rats to test the hypothesis that gastrocnemius (a locomotor muscle) demonstrates reduced fiber size with aging, whereas soleus (a postural muscle) demonstrates atrophy of some fibers and compensatory hypertrophy in other fibers. Although body mass

Controversy exists as to the clinical importance, cause, and disease specificity of the cytochrome oxidase (CO) activity reduction observed in some patients with Alzheimer's disease (AD). Although it is assumed that the enzyme is present in normal amount in AD, no direct measurements of specific CO

This study investigates the effects of advancing age on responses of nasolabialis muscle fibers to denervation and reinnervation. The nasolabialis is innervated by the facial nerve and is responsible for the whisking movement of the animal's large vibrissae. In young adult (3-month) and middle-aged

We examined the pattern of cytochrome oxidase (CO), Nissl staining, and gamma-amino butyric acid (GABA) immunoreactivity in the ventroposterior lateral nucleus (VPL) of the thalamus in monkeys that received no, total, or subtotal, ablation of the hand representations in postcentral somatosensory

Sporadic Amyotrophic Lateral Sclerosis (SALS) is a fatal neurologic disease characterized by degeneration of motor neurons in the spinal cord, brainstem and cortex. While familial cases of ALS exist, the sporadic form accounts for the majority of adult-onset cases. It has been hypothesized that the

The excitotoxic hypothesis of Huntington's disease pathogenesis suggests that selective striatal neuronal loss results from excessive activation of striatal excitatory amino acid receptors. Using a microdialysis probe mated to an Alzet 2002 mini-osmotic pump three different concentrations of

Our previous studies showed atrophy of brown adipose tissue (BAT) in capsaicin-desensitized rats during the period 11-28 days after injections [Cui et al., Am. J. Physiol. 259 (Regulatory Integrative Comp. Physiol. 28): R324-R332, 1990]. The objective of the present studies was to assess the

Selective degeneration of retinal ganglion cells projecting to parvocellular layers of the dorsal lateral geniculate nucleus (LGN) was observed in squirrel monkeys (Saimiri sciureus) exposed to a range of doses of acrylamide monomer. Similar acrylamide-induced neuronal loss has previously been

Early postnatal lesions of the primary somatosensory cortex alter the vibrissa-related cytochrome oxidase (CO) pattern in nucleus principalis (PrV) of the rat's trigeminal (V) brainstem complex (Erzurumlu and Ebner, '88: Dev. Brain Res. 44:302-308). At present, the reason for this change is not

P beta (color opponent) retinal ganglion cells in macaques were found to degenerate as a result of oral administration of acrylamide. Histological examination, wheat germ agglutinin-horseradish peroxidase transport and cytochrome oxidase histochemistry indicate that other retinal ganglion cells and
