Sleep Deprivation Alters T Cell Dynamics: Melatonin as a Restorative Agent

open access: yesJournal of Sleep Research, Volume 35, Issue 2, April 2026.
ABSTRACT Sleep is an essential physiological function regulated by circadian rhythm and homeostatic regulation for emotional and physical health. Conversely, sleep deprivation (SD) is associated with weakened immune system function and overall health, which potentially leads to chronic diseases such as heart disease and diabetes.

Behavioral Phenotype and Neuropsychological Profile of an Adult With Smith‐Magenis Syndrome due to a Previously Unreported RAI1 Mutation: A Case Report

open access: yesClinical Case Reports, Volume 14, Issue 3, March 2026.
ABSTRACT Smith‐Magenis Syndrome (SMS) is an uncommon genetic disorder caused by microdeletions of chromosome 17p11.2 including the RAI1 gene, or loss‐of‐function mutations that directly affect RAI1. Due to the involvement of RAI1 in neurodevelopment, SMS leads to typical pathologic features in the behavioral and physical phenotype that must be ...

Circadian Pattern of Melatonin MT1 and MT2 Receptor Localization in the Rat Suprachiasmatic Nucleus

open access: yesJournal of Circadian Rhythms, 2015
The suprachiasmatic nucleus (SCN) is the circadian pacemaker. The pineal hormone melatonin is involved in the regulation of circadian phase. As a part of the circadian system its synthesis and secretion is under SCN control.

Correlation between sleep problems and morning serum melatonin and ferritin levels in Japanese 5‐year‐old children with autism spectrum disorder

open access: yesPsychiatry and Clinical Neurosciences Reports, Volume 5, Issue 1, March 2026.
Abstract Aim Children with autism spectrum disorder (ASD) are more likely to have sleep problems. Few studies have investigated the relationship between sleep problems and blood melatonin and ferritin levels. The objective of this study was to determine the correlation between sleep problems and morning serum melatonin and ferritin levels, and the ...

Characterization of Phytoene Desaturase Knockout Carotenoid‐Deficient Microalgal Mutants Generated by Cas9‐Ribonucleoprotein Complexes

open access: yesPhysiologia Plantarum, Volume 178, Issue 2, March/April 2026.
ABSTRACT Phytoene desaturase (PDS; EC 1.3.5.5) is a key enzyme of the carotenoid biosynthetic pathway, catalyzing the desaturation of phytoene, precursor of all carotenoids. In this study, several PDS‐knockout (PDS‐KO) transformants of the chlorophyte microalga Chlamydomonas reinhardtii were generated using a reverse genetics strategy. Two single guide

Properties of MT2 in the massless limit

open access: yes, 2012
Although numerical methods are required to evaluate the stransverse mass, MT2, for general input momenta, non-numerical methods have been proposed for some special clases of input momenta. One special case, considered in this note, is the so-called `massless limit' in which all four daughter objects (comprising one invisible particle and one visible ...

Comparative Analysis of High‐Throughput Phenotyping Techniques for Early Detection of Herbicide Stress

open access: yesWeed Research, Volume 66, Issue 2, March/April 2026.
ABSTRACT Early detection of herbicide‐induced stress is essential for optimising weed control, improving crop safety and advancing precision agriculture practices. While non‐destructive imaging technologies offer great potential for rapid stress diagnosis, direct comparisons of their performance across species, herbicides and application rates remain ...

Sleep quality and sleepiness in adults with multiple myeloma. Is melatonin a potential treatment?

open access: yesPhysiological Reports, Volume 14, Issue 5, March 2026.
Abstract Sleep disturbances significantly impact quality of life in cancer patients, yet remain poorly characterized in multiple myeloma (MM). This observational study aimed to characterize sleep profiles in MM patients and evaluate the therapeutic potential of exogenous melatonin.

Pineal and cortical melatonin receptors MT1 and MT2 are decreased in Alzheimer’s disease

open access: yesEuropean Journal of Histochemistry, 2009
The pineal hormone melatonin is involved in physiological transduction of temporal information from the light dark cycle to circadian and seasonal behavioural rhythms, as well as possessing neuroprotective properties.
