Objective(s): Melatonin, an important hormone secreted by the epiphysis, is a powerful anti-oxidant with a high potential to neutralize medical toxins. The goal of this study was to demonstrate the beneficial effect of melatonin on epididymal sperm and reproductive parameters in mice treated with acetylsalicylic acid (ASA).Materials and Methods:</stro...

Introduction: Donepezil (DON), an Acetylcholinesterase Inhibitor (AChEI), is widely used in the treatment of Alzheimer’s Disease (AD). The current study aimed at evaluating the effect of donepezil hydrochloride on pyramidal neuron response in CA1 region of a rat model of AD. Methods: In the current experimental study, adult male Wistar rats were randomly divided into four groups: Nucleus Basal...

Treatment of rats in vivo with NGF promotes the survival and enhances the neurotransmitter phenotype of basal forebrain cholinergic neurons. We showed recently (Williams et al., 1993) that NGF-induced stimulations of the cholinergic markers ChAT and high-affinity choline uptake are reflected in an enhanced synthesis and release of ACh in terminals fields of basal forebrain cholinergic neurons. ...

The immunotoxin 192 IgG-saporin, produced by coupling the ribosome-inactivating protein saporin to the monoclonal 192 IgG antibody against the low-affinity p75 NGF receptor (NGFr), was injected into the cerebral ventricle, septal area, and substantia innominata of adult rats. Injections into the cerebral ventricle induced a complete loss of NGFr-positive basal forebrain neurons and their axons....

This study investigated the egg-laying behaviour of ectoparsitoid, Dinarmus basalis Rondani (Hymenoptera: Pteromalidae), females when faced with a prolonged deprivation of suitable hosts leading to extreme 'oviposition pressure'. The egg-laying behaviour of virgin D. basalis females was tested with Callosobruchus maculatus (F.) (Coleoptera: Bruchidae) hosts previously parasitized by the conspec...

Cerebral atrophy is one of the most widely brain alterations associated to aging. A clear relationship has been established between age-associated cognitive impairments and cerebral atrophy. The mouse lemur (Microcebus murinus) is a small primate used as a model of age-related neurodegenerative processes. It is the first non-human primate in which cerebral atrophy has been correlated with cogni...
