Morphological and molecular characterization of two trematode worms in the gastropod Asolene pulchella (Anton, 1859) [PDF]

open access: yes, 2019
Asolene pulchella (Anton, 1859) Asolene pulchella (Caenogastropoda, Ampullariidae) is a native gastropod from La Plata River. In a previous study we reported the presence of parasite forms of Trematoda (Plathyhelminthes) in the digestive gland of adult ...

Melatonin uptake by cells: An answer to its relationship with glucose? [PDF]

open access: yes, 2018
Melatonin, N-acetyl-5-methoxytryptamine, is an indole mainly synthesized from tryptophan in the pineal gland and secreted exclusively during the night in all the animals reported to date.

Histomorphometric examination of the pineal gland in foals and adult horses [PDF]

open access: yes, 2018
WOS: 000425921400014This study was conducted to evaluate the pineal glands of the foal and adult horses with histomorphometry. The pineal glands were sectioned at a thickness of 40 mu m and stained with AgNOR for stereological analyses.

Noradrenaline upregulates T‐type calcium channels in rat pinealocytes [PDF]

open access: yesThe Journal of Physiology, 2015
Key points The mammalian pineal gland is a neuroendocrine organ that responds to circadian and seasonal rhythms. Its major function is to secrete melatonin as a hormonal night signal in response to nocturnal delivery of noradrenaline from sympathetic neurons. Culturing rat pinealocytes in noradrenaline for 24 h induced a low‐voltage activated transient

The pinealocytes of the human pineal gland: a light and electron microscopic study [PDF]

open access: yes, 2006
The pinealocytes of the pineal gland of children and adults were studied at both light and electron microscopic levels. The pinealocytes were classified into light and dark pinealocytes on the basis of their shape, nuclear infolding, cytoplasmic contents

THE ANATOMICAL RELATIONSHIPS, ULTRASTRUCTURE, AND FUNCTION OF THE PINEAL GLAND IN SOME COMMON LABORATORY RODENTS [PDF]

open access: yes, 1972
The pineal complex of rodents is made up of a pineal organ which developmentally always originates from the area between the habenular and posterior commissure and a pineal sac which is continuous with the choroid plexus of the third ventricle.
