The Role of Pineal Gland and Exogenous Melatonin on the Irradiation Stress Response of Suprarenal Gland

open access: yesBiomolecules & Biomedicine, 2006
Pineal gland has and antistressogenic role. Its main hormone, melatonin, has radio protective effect on endocrine and other dynamic tissues. In our previous study, we have shown that pinealectomy changes the behavior of suprarenal gland in totally ...

De Novo 2.2 Mb 19q13.42–q13.43 Microdeletion Encompassing U2AF2: Support for a Haploinsufficiency Model

open access: yesAmerican Journal of Medical Genetics Part A, Volume 200, Issue 10, Page 2350-2356, October 2026.
ABSTRACT U2 small nuclear RNA auxiliary factor 2 (U2AF2) is an essential pre‐mRNA splicing factor involved in the early stages of pre‐mRNA splicing. To date, multiple individuals have been reported with predominantly heterozygous missense variants presenting intellectual disability, speech and motor delays, seizures, hypotonia, and thin or hypoplastic ...

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

open access: yesСибирский 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

in pinealocytes of the rat pineal gland

open access: yes, 2023
Melatonin is synthesized in the pineal gland during nighttime in response to nocturnal increase in the activity of the enzyme aralkylamine N-acetyltransferase (AANAT), the transcription of which is modulated by several homeodomain transcription factors ...

Neuroanatomical diversity in Teleocichla with new volumetric and histological insights into the encephalon of Teleocichla monogramma Kullander 1988

open access: yesThe Anatomical Record, Volume 309, Issue 10, Page 2897-2912, October 2026.
Abstract Teleocichla comprises small cichlids that inhabit the rapid streams of Amazonian rivers; however, there has been limited research on their encephalon morphology. This study examined the neuroanatomy of four species, focusing on volumetric measurements of their encephalon subregions, and providing a histological description of the encephalon of

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

open access: yesFrontiers 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 ...

A Rapid and Sensitive LC–MS/MS Method for Quantification of NDSRI in Melatonin Drug Product via Controlled In Situ Formation

open access: yesBiomedical Chromatography, Volume 40, Issue 10, October 2026.
ABSTRACT Nitrosamine drug substance–related impurities (NDSRIs) pose a significant safety risk due to their mutagenic and carcinogenic potential, prompting strict regulatory oversight under ICH M7. The propensity for in situ formation of NDSRIs during analytical procedures, particularly in active pharmaceutical ingredients containing reactive amines ...
