Following optic nerve crush in the adult lizard Ctenophorus ornatus, most retinal ganglion cells regrow their axons into visual brain centres: however, the regenerated projections lack retinotopic order and the animals are blind via the experimental eye. Here we have used 3H-thymidine

The neural mechanisms by which steroid hormones regulate aggression are unclear. Although testosterone and its metabolites are involved in both the regulation of aggression and the maintenance of neural morphology, it is unknown whether these changes are functionally related. We addressed the

Exposure to continuous loud noise is a serious health problem due to excess production of oxygen free radicals. In medical research, more attention is paid to the antioxidant properties of medicinal plants to minimize the harmful effects of radicals. The aim of this study was to evaluate the

OBJECTIVE Prolonged exposure to stress mainly affects the cognitive functions of the brain by inducing neuronal damage mediated through oxidative stress. Acorus calamus (AC) has long been used in Indian folk medicine for various central nervous system (CNS) abnormalities. Hence the present study

In an attempt to determine whether scrapie infectivity can be found in the peripheral nervous system of a scrapie-diseased sheep, mice were inoculated intracerebrally or intraperitoneally with 10-fold dilutions of homogenates of Nervus (N.) axillaris, N. ulnaris, N. medianus, N. ischiadicus, N.

The neuropeptide arginine vasotocin (AVT) and its mammalian homologue arginine vasopressin (AVP) are neuromodulators known to be steroid sensitive and associated with social behaviors in a number of vertebrate taxa. However, the role of AVT/P in the regulation of aggression remains unclear and

The mechanisms by which testosterone regulates aggression are unclear and may involve changes that alter the activity levels of one or more brain nuclei. We estimate neural activity by counting immunopositive cells against phosphorylated cyclic AMP response element binding protein (pCREB). We

Acorus calamus L., a tall, perennial, grass-like monocot plant from the Acoraceae family, is a well-known plant in Indian traditional medicines for centuries. It is a highly valued herb as it acts as a rejuvenator for brain and nervous system. It is a main medhya drug, which has the property of

The radioprotecting activity of Acorus calamus extract after whole body exposure of mice to lethal and sub-lethal doses of γ-irradiation in terms of radiation induced mortality and damages to cellular DNA and tissue antioxidant levels were studied. A. calamus extract (250 mg/kg body weight) was

UNASSIGNED Several factors lead to memory loss, the most important of which is brain aging that is caused mostly by neuroinflammation and oxidative stress. The need of finding preventive treatments of memory impairment in elderly encouraged authors to assess the effect of Acorus calamus on memory

Steroid hormones effect changes in both neuroanatomy and aggressive behavior in animals of various taxa. However, whether changes in neuroanatomy directly underlie changes in aggression is unknown. We investigate this relationship among steroid hormones, neuroanatomy, and aggression in a free-living

Optic nerve regeneration within the reptiles is variable. In a snake, Viper aspis, and the lizard Gallotia galloti, regeneration is slow, although some retinal ganglion cell (RGC) axons eventually reach the visual centers (Rio et al. [1989] Brain Res 479:151-156; Lang et al. [1998] Glia 23:61-74).

BACKGROUND Wolf Dietrich of Raitenau (WD) ruled the archiepiscopal Salzburg from March 2nd 1587 to December 17th 1611. He was condemned by his successor Archbishop Markus Sittikus of Hohenems to spend his last years imprisoned at the Fortress Hohensalzburg, where he died on January 16th 1617. This
