Fresh insights into the light‐induced pineal gland circadian rhythm transmission mechanism derived from mRNA and miRNA profiling

Animal Research and One Health, EarlyView.
Mechanisms of light in regulating the chick pineal clock. Abstract The circadian clock significantly impacts animal health and productivity, with light playing a crucial role in regulating circadian rhythms. However, the mechanisms behind light‐induced circadian transmission remain unclear, particularly in light‐sensitive avian species.

Time\u27s Arrow Flies Like a Bird: Two Paradoxes for Avian Circadian Biology [PDF]

, 2009
Biological timekeeping in birds is a fundamental feature of avian physiology, behavior and ecology. The physiological basis for avian circadian rhythmicity has pointed to a multi-oscillator system of mutually coupled pacemakers in the pineal gland, eyes ...

A Proteomics Profiling Reveals the Neuroprotective Effects of Melatonin on Exogenous β‐amyloid‐42 Induced Mitochondrial Impairment, Intracellular β‐amyloid Accumulation and Tau Hyperphosphorylation in Human SH‐SY5Y Cells

Cell Biology International, EarlyView.
ABSTRACT Alzheimer's disease (AD) is prevalent in the elderly population and characterized by the intracellular accumulation of neurofibrillary tangles (NFTs), composed of tau proteins, and extracellular deposition of beta‐amyloid protein (Aβ). The present study aimed to investigate the neuroprotective effects of melatonin on Aβ42‐induced AD‐like ...

The light-induced transcriptome of the zebrafish pineal gland reveals complex regulation of the circadian clockwork by light

Nucleic Acids Research, 2014
Light constitutes a primary signal whereby endogenous circadian clocks are synchronized (‘entrained’) with the day/night cycle. The molecular mechanisms underlying this vital process are known to require gene activation, yet are incompletely understood ...

HISTOMORPHOGENESIS OF PINEAL GLAND IN GOAT FOETUSES [PDF]

Journal of Veterinary and Animal Sciences, 2011
Prenatal development of pineal gland in goat was studied using 52 goat foetuses ranging from 1.4cm CRL (24 days of gestation) to 41.5cm CRL (full term). Pineal gland developed during the seventh week as a conical evagination on the caudo-dorsal aspect of

Gland Segmentation Via Dual Encoders and Boundary-Enhanced Attention [PDF]

ICASSP 2024 - 2024 IEEE International Conference on Acoustics, Speech and Signal Processing (ICASSP), Seoul, Korea, Republic of, 2024, pp. 2345-2349,
Accurate and automated gland segmentation on pathological images can assist pathologists in diagnosing the malignancy of colorectal adenocarcinoma. However, due to various gland shapes, severe deformation of malignant glands, and overlapping adhesions between glands. Gland segmentation has always been very challenging.

Neural Annotation Refinement: Development of a New 3D Dataset for Adrenal Gland Analysis [PDF]

arXiv, 2022
The human annotations are imperfect, especially when produced by junior practitioners. Multi-expert consensus is usually regarded as golden standard, while this annotation protocol is too expensive to implement in many real-world projects. In this study, we propose a method to refine human annotation, named Neural Annotation Refinement (NeAR).

Imaging Assessment of the Pituitary Gland and Long‐Term Endocrinological Abnormalities in Pediatric Brain Cancer Survivors

Journal of Magnetic Resonance Imaging, EarlyView.
Background Pediatric brain cancer survivors often experience hypothalamic–pituitary dysfunction due to cranial irradiation and chemotherapy. While hormone deficiencies have been studied, the changes in pituitary size and shape on long‐term MRI and their relationship to endocrine dysfunction remain under‐explored.

The Contribution of the Pineal Gland on Daily Rhythms and Masking in Diurnal Grass Rats, Arvicanthis niloticus [PDF]

, 2016
Melatonin is a hormone rhythmically secreted at night by the pineal gland in vertebrates. In diurnal mammals, melatonin is present during the inactive phase of the rest/activity cycle, and in primates it directly facilitates sleep and decreases body ...
