Nitric oxide synthase in the pineal gland [PDF]
, 1996 The recent discovery of nitric oxide (NO) as a biological messenger molecule with unique characteristics has opened a new field in pineal research. This free radical gas is synthesized by the enzyme nitric oxide synthase (NOS) from L-arginine.

The hormonal Zeitgeber melatonin: role as a circadian modulator in memory processing
, 2012 The neuroendocrine substance melatonin is a hormone synthesized rhythmically by the pineal gland under the influence of the circadian system and alternating light/dark cycles. Melatonin has been shown to have broad applications, and consequently becoming

Journal of Cellular and Molecular Medicine, Volume 30, Issue 11, June 2026.ABSTRACT Melatonin signalling, mediated by membrane receptors and tightly regulated biosynthetic enzymes, is a key component of circadian and neuroendocrine control in the brain. However, whether the tryptophan–melatonin axis remains hierarchically intact during glioma progression and how its disruption affects downstream signalling remain unclear.

Journal of the World Aquaculture Society, Volume 57, Issue 3, June 2026.Abstract Photoperiod manipulation is widely used to regulate reproduction in temperate fish species, but little is known about its effects in strictly tropical species. This study evaluated whether the Emperor tetra (Nematobrycon palmeri), a tropical ornamental fish, can modulate sexual maturation in response to artificial light regimes.

Perinatal White Matter Injury: Connecting Histology, Pathophysiology and Neurodevelopmental Outcomes
Neuropathology and Applied Neurobiology, Volume 52, Issue 3, June 2026.Perinatal white matter injury is associated with high rates of adverse neuropsychiatric outcomes and millions of years lived with disability. This review focuses on the macroscopic and microscopic features of perinatal white matter injury and how these relate to the proposed pathophysiology of this disease and adverse neurodevelopmental outcomes ...
