Cervical Spinal Cord Metastasis of Germ Cell Tumor: A Rare Case Report

open access: yesClinical Case Reports, Volume 13, Issue 10, October 2025.
ABSTRACT Malignant germ cell tumors (GCTs) spreading to the central nervous system (CNS) are uncommon, particularly when it comes to spinal cord metastases, which are extremely rare. This report details a case involving a metastatic cervical spinal cord GCT in a patient who had previously been diagnosed with a primary malignant GCT of the right ...

The role of the pineal gland in seasonality

open access: yesBioscientifica Proceedings, 2019
The life time reproductive performance of 2 flocks of Merino crossbred ewes pinealectomized at 7-60 days of age, and maintained in South Australia did not differ from that of sham-operated control animals kept in the same flocks. The pineal gland is therefore not a major determinant of reproductive success, but a role for the pineal in adjusting ...

Neurodevelopmental Impact of Prenatal Stress: A Proteomic Analysis of Myelination Disruptions in the Avian Embryo

open access: yesDevelopmental Neurobiology, Volume 85, Issue 4, October 2025.
ABSTRACT Prenatal stress, mediated by elevated glucocorticoid (GC) levels, is a relevant modulator of fetal brain development and a known risk factor for neurodevelopmental disorders. Using the avian embryo as a vertebrate model, we injected corticosterone into the yolk on embryonic day 6 (E6) and assessed neurodevelopmental outcomes at day 14 (E14 ...

The Effects of Food on Circadian Rhythm: A Comprehensive Review

open access: yeseFood, Volume 6, Issue 5, October 2025.
(a) Light signals are received by the retina and transmitted to the suprachiasmatic nucleus (SCN), the master circadian clock, which synchronizes peripheral clocks in metabolic tissues via neural and humoral pathways (e.g., cortisol). (b) The molecular clock is governed by a transcriptional‐translational feedback loop.

The Colour Changes In Lizards, Particularly In Phrynosoma [PDF]

open access: yes, 1938
The activities of the melanophore system of Phrynosoma in comparison with that of Chamaeleo may be stated categorically in the following way. I. The blanching of Phrynosoma blainvillii is due (1) to the action of its concentrating nerve-fibres on ...
