A Morphological and Behavioral Study of Demyelination and Remyelination in the Cuprizone Model: Insights into APLNR and NG2+ Cell Dynamics.

Multiple sclerosis (MS) is a chronic neurodegenerative disorder involving demyelination. The cuprizone model is commonly used to study MS by inducing oligodendrocyte stress and demyelination. The subventricular zone (SVZ) plays a key role in neurogenesis, while the neuronal/glial antigen 2 (NG2) is a marker for immature glial cells, involved in oligodendrocyte differentiation.

Morphological characteristics of the canine and feline stomach mucosa.

The stomach mucosa structure in animals belonging to Order Carnivora indicates some specific characteristics in comparison with the other mammals. Between the bases of the mucosal glands and the lamina muscularis mucosae there is an additional plate which most of the morphologists have defined as lamina subglandularis. In currently used Nomina histologica this layer is indicated as stratum compactum in carnivorous stomach mucosa.

Fibroleiomyoma in elephant uterus.

The result of the histological diagnosis from postmortal investigation of the Indian elephant (Elephas maximus) uterus structure is presented in the current study. The rare anatomical finding showed altered nodular part from the uterus wall. Through conventional and histochemical staining neoplasmatic formations were determined and diagnosis Fibroleiomyoma was established, which should not be accepted as the prime cause for the animal's death.
