Ultaradian oscillation in expression of four melatonin receptor subtype genes in the pineal gland of the grass puffer, a semilunar-synchronized spawner, under constant darkness

Frontiers in Neuroscience, 2015
Melatonin receptor gene expression as well as melatonin synthesis and secretion activities were examined in the pineal gland of the grass puffer, which exhibits unique lunar/tidal cycle-synchronized mass spawing: spawning occurs before high tide on the ...

Rythme nycthéméral de la sécrétion de mélatonine chez le dromadaire (Camelus dromedarius) [PDF]

, 1997
La mélatonine, une hormone secrétée par la glande pinéale, a été dosée sur trois chamelles vivant dans le Sud de la France. Comme pour les autres espèces domestiques, les résultats montrent qu'il existe un rythme nycthéméral de la sécrétion de cette ...

Circadian‐Related Serotonin/Melatonin Level Modulates Cisplatin Ototoxicity Susceptibility Depended on NOS3–NO Pathway

Journal of Pineal Research, Volume 78, Issue 4, July 2026.
ABSTRACT Hearing impairment is attributed to factors such as age, genetic predisposition, and environmental influences, among which environmental factors are considered modifiable. Among various environmental factors, the role of poor lifestyle habits is particularly critical, yet the specific mechanisms by which they contribute to hearing damage ...

Peculiarities of psammoma bodies distribution in the human pineal gland: a new approach to determining the functional significance of pineal gland calcifications

Сибирский научный медицинский журнал
The pineal gland is a neuroendocrine gland that synchronizes the functional activity of body organs with the light regime using the hormone melatonin, which is actively released into the bloodstream at night. Melatonin is synthesized by pinealocytes, the

5‐Hydroxytryptamine Distribution Alteration in Both Neuron and Synapse of Tg(SOD1*G93A)1gur Mice: A Potential Intervention Candidate Strategy for Amyotrophic Lateral Sclerosis

CNS Neuroscience &Therapeutics, Volume 32, Issue 6, June 2026.
This study reveals that 5‐hydroxytryptamine (5‐HT) synapses in the spinal cord and 5‐HT neurons in the brainstem of the SOD1‐G93A amyotrophic lateral sclerosis (ALS) mouse model are significantly altered, showing a decrease in pre‐symptomatic stages but a marked increase as the disease progresses.

The Colour Changes In Lizards, Particularly In Phrynosoma [PDF]

, 1938
The activities of the melanophore system of Phrynosoma in comparison with that of Chamaeleo may be stated categorically in the following way. I. The blanching of Phrynosoma blainvillii is due (1) to the action of its concentrating nerve-fibres on ...

Expanding the Phenotypic Spectrum Associated With Loss‐of‐Function SMARCA4 Variants to Eye Developmental Anomalies

Clinical Genetics, Volume 109, Issue 6, Page 1064-1069, June 2026.
This study expands the clinical spectrum of SMARCA4 by describing a novel phenotype in three unrelated individuals with truncating variants. Distinct from Coffin–Siris syndrome and rhabdoid tumor predisposition, this new association is characterized by ocular malformations, specifically microphthalmia and coloboma.

In silico genome wide mining of conserved and novel miRNAs in the brain and pineal gland of Danio rerio using small RNA sequencing data

Genomics Data, 2016
MicroRNAs (miRNAs) are small, non-coding RNA molecules that bind to the mRNA of the target genes and regulate the expression of the gene at the post-transcriptional level. Zebrafish is an economically important freshwater fish species globally considered

Kinding Culture

Journal for the Theory of Social Behaviour, Volume 56, Issue 2, June 2026.
ABSTRACT Progress and dialogue in cultural analysis are often hindered by analysts' reliance on implicit ontic claims, namely, foundational, unstated assumptions about the expected properties and typical characteristics of cultural kinds, thus precluding proper debate and theoretical progress.
