Melatonin in Male Dromedary Camel (Camelus dromedarius) Seminal Plasma and Its Specific MT1 and MT2 Receptors on Sperm Membranes

Animals
Camels (Camelus dromedarius) are seasonal short-day breeders, regulated by photoperiod and melatonin secretion. However, no studies have explored melatonin levels in camel seminal plasma or their relationship with testosterone, age, or climatic factors ...

Abnormal hippocampal melatoninergic system: a potential link between absence epilepsy and depression-like behavior in WAG/Rij rats? [PDF]

, 2018
Absence epilepsy and depression are comorbid disorders, but the molecular link between the two disorders is unknown. Here, we examined the role of the melatoninergic system in the pathophysiology of spike and wave discharges (SWDs) and depression-like ...

Identification of Melatonin-Regulated Genes in the Ovine Pituitary Pars Tuberalis, a Target Site for Seasonal Hormone Control [PDF]

, 2008
The pars tuberalis (PT) of the pituitary gland expresses a high density of melatonin (MEL) receptors and is believed to regulate seasonal physiology by decoding changes in nocturnal melatonin secretion.

Influence of melatonin on the development of functional nicotinic acetylcholine receptors in cultured chick retinal cells

Brazilian Journal of Medical and Biological Research, 2005
The influence of melatonin on the developmental pattern of functional nicotinic acetylcholine receptors was investigated in embryonic 8-day-old chick retinal cells in culture. The functional response to acetylcholine was measured in cultured retina cells

Fluorescent Nanosensor for Indole‐3‐Propionic Acid Detection in Gut Health Monitoring

Advanced Healthcare Materials, EarlyView.
This work introduces a fluorescent nanosensor system with two optical modalities for detection of indole‐3‐propionic acid (IPA) gut metabolite: (1) blue‐emitting cationic conjugated polyelectrolyte (CP3) and (2) near‐infrared (NIR)‐emitting CP3‐wrapped single‐walled carbon nanotube (SWNT).

Dysfunctional Light-Evoked Regulation of cAMP in Photoreceptors and Abnormal Retinal Adaptation in Mice Lacking Dopamine D4 Receptors [PDF]

, 2002
Dopamine is a retinal neuromodulator that has been implicated in many aspects of retinal physiology. Photoreceptor cells express dopamine D4 receptors that regulate cAMP metabolism.

Preliminary Evaluation of Human Gingiva as an Extrapineal Site of Melatonin Biosynthesis in States of Periodontal Health and Disease [PDF]

Journal of Clinical and Diagnostic Research, 2018
Introduction: Melatonin is a pineal gland hormone that plays an important role in periodontal homeostasis. Extra pineal melatonin production has been found to occur in tissues like the ovaries, retina and gastrointestinal tract.
