CALCIFICATION IN THE PINEAL GLAND [PDF]

open access: yesArchives of Internal Medicine, 1918
Pathologic as well as roentgenologic literature on calcification of the pineal gland is very scarce. Schueller,1apparently, was the first to demonstrate concretions in the gland radiographically, and the only one to verify his roentgen-ray findings by necropsy.

Genetically Blocking the Zebrafish Pineal Clock Affects Circadian Behavior. [PDF]

open access: yesPLoS Genetics, 2016
The master circadian clock in fish has been considered to reside in the pineal gland. This dogma is challenged, however, by the finding that most zebrafish tissues contain molecular clocks that are directly reset by light.

Pineal gland dysfunction in Alzheimer’s disease: relationship with the immune-pineal axis, sleep disturbance, and neurogenesis

open access: yesMolecular Neurodegeneration, 2019
Alzheimer’s disease (AD) is a globally common neurodegenerative disease, which is accompanied by alterations to various lifestyle patterns, such as sleep disturbance.

Content of microelements in the rat pineal gland at different ages and the effects of selenium supplementation [PDF]

open access: yesArchives of Biological Sciences, 2006
The mammalian pineal gland regulates a number of important physiological processes. In this paper we report changes in the content of iron (Fe), zinc (Zn), copper (Cu), and selenium (Se) in the male rat pineal glands at 4, 5, 8, and 12 months of age. The

Biosynthesis and biological action of pineal allopregnanolone

open access: yesFrontiers in Cellular Neuroscience, 2014
The pineal gland transduces photoperiodic changes to the neuroendocrine system by rhythmic secretion of melatonin. We recently provided new evidence that the pineal gland is a major neurosteroidogenic organ and actively produces a variety of ...

Glia-pinealocyte network: the paracrine modulation of melatonin synthesis by tumor necrosis factor (TNF). [PDF]

open access: yesPLoS ONE, 2012
The pineal gland, a circumventricular organ, plays an integrative role in defense responses. The injury-induced suppression of the pineal gland hormone, melatonin, which is triggered by darkness, allows the mounting of innate immune responses.

Melatonin receptor expression in the zebra finch brain and peripheral tissues [PDF]

open access: yes, 2012
The circadian endocrine hormone melatonin plays a significant role in many physiological processes such as modulating sleep/wake cycle and oxidative stress.

Shell Neurons of the Master Circadian Clock Coordinate the Phase of Tissue Clocks Throughout the Brain and Body [PDF]

open access: yes, 2015
Background: Daily rhythms in mammals are programmed by a master clock in the suprachiasmatic nucleus (SCN). The SCN contains two main compartments (shell and core), but the role of each region in system-level coordination remains ill defined.

Profiling Temporal Changes of the Pineal Transcriptomes at Single Cell Level Upon Neonatal HIBD

open access: yesFrontiers in Cell and Developmental Biology, 2022
Neonatal hypoxic-ischemic brain damage (HIBD) often results in various neurological deficits. Among them, a common, yet often neglected, symptom is circadian rhythm disorders. Previous studies revealed that the occurrence of cysts in the pineal gland, an

Macro-microscopical aspects of the buffalo (Bubalus bubalis Linnaeus, 1758) pineal gland [PDF]

open access: yesBiotemas, 2009
Gross and microscopical aspects of the buffalo pineal gland were described in seasonal parturition animals, since this gland is responsible for melatonin secretion which acts upon the hypothalamus-hypophysis reproductive axis feedback system.
