Distribution of gamma‐aminobutyric acid immunoreactivity in the brain of the Siberian sturgeon (Acipenser baeri): Comparison with other fishes

open access: yesJournal of Comparative Neurology, Volume 532, Issue 2, February 2024.
Inmunohistochemical methods showed that GABAergic cells, fibers, and terminals are widely distributed throughout the brain and spinal cord of the sturgeon. Comparison among sturgeon and other vertebrates, revealed numerous differences in the complexity of specific subsystems reflecting different trends followed by vertebrate brains during evolution ...

Circadian genomics of the chick pineal gland in vitro [PDF]

open access: yes, 2008
Background Chick pinealocytes exhibit all the characteristics of a complete circadian system, comprising photoreceptive inputs, molecular clockworks and an easily measured rhythmic output, melatonin biosynthesis. These properties make the in vitro pineal

Nocturnal Light Pollution Synergistically Impairs Glucose Metabolism With Age and Weight in Monkeys

open access: yesJournal of Diabetes Research, Volume 2024, Issue 1, 2024.
Over the past decades, the global prevalence of Type 2 diabetes mellitus (T2D) and impaired glucose tolerance (IGT) has been increasing at an epidemic rate, yet the exact cause remains unknown. It is widely accepted that glucose metabolism can be impaired by circadian rhythms and sleep disturbances.

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.

P76 | PERICAPILLARY SPACES IN THE SHEEP PINEAL GLAND – 2D AND 3D ANALYSIS

open access: yesEuropean Journal of Histochemistry
The structural organization of pericapillary spaces in the mammalian pineal gland varies significantly among species. In rats - the most widely used in pineal research - fenestrated capillaries are surrounded by wide pericapillary spaces rich in ...

Microstructural aspect of pineal body: pinealocytes population

open access: yesIntisari Sains Medis, 2018
Background: Pineal tissue was compound with 2 types of cell known as pinealocytes and astrocyte cell. Furthermore, microanatomical research of pineal body is a rare procedure conducted for several years even in Indonesia, and its anatomical aspect needs to be explained.  Aim: enrich the scope of knowledge related to mammalian pineal within the pineal

COSMOS 2044. Experiment K-7-19. Pineal physiology in microgravity: Relation to rat gonadal function [PDF]

open access: yes
It is now known that the pineal organ can interact with many endocrine and nonendocrine tissues in a regulatory fashion. Given its key role in the regulation of melatonin synthesis, its high concentration, and that its levels may persist longer than the ...
