Blast Exposure Induces Acute Alterations in Circadian Clock Genes in the Hypothalamus and Pineal Gland in Rats: An Exploratory Study

open access: yesNeurotrauma Reports, 2023
Blast-induced traumatic brain injury (bTBI) frequently results in sleep and circadian rhythm disturbances. We have investigated whether dysregulation of circadian rhythm after bTBI is mediated by dysregulation of clock genes in the hypothalamus and ...

Characterization of N6-Cyclohexyladenosine-Induced Hypothermia in Syrian Hamsters

open access: yesJournal of Pharmacological Sciences, 2005
The N6-cyclohexyladenosine (CHA)-induced hypothermia in Syrian hamsters was characterized as follows: intracerebroventricular injection of CHA-induced hypothermia and the potency was increased by lowering the ambient temperature.

Age changes in the tigroid substance of neutrons of the lateral preoptic nucleus of hypothalamus under different light modes

open access: yesJournal of Education, Health and Sport, 2021
The article presents analysis of the results of the original histochemical studies of tigroid substance of neurons of the lateral preoptic nucleus of  hypothalamus in mature and old rats under the influence of different light modes. In all observations,

Identification of sex hormone-binding globulin in the human hypothalamus [PDF]

open access: yes, 2005
Gonadal steroids are known to influence hypothalamic functions through both genomic and non-genomic pathways. Sex hormone-binding globulin ( SHBG) may act by a non-genomic mechanism independent of classical steroid receptors.

The Visually Related Posterior Pretectal Nucleus in the Non-Percomorph Teleost Osteoglossum bicirrhosum Projects to the Hypothalamus [PDF]

open access: yes, 1991
This study was done to elucidate the ancestral (plesiomorphic) condition for visual pathways to the hypothalamus in teleost fishes. Three patterns of pretectal organization can be discerned morphologically and histochemically in teleosts. Their taxonomic

The orexigenic effect of ghrelin is mediated through central activation of the endogenous cannabinoid system [PDF]

open access: yes, 2008
INTRODUCTION: Ghrelin and cannabinoids stimulate appetite, this effect possibly being mediated by the activation of hypothalamic AMP-activated protein kinase (AMPK), a key enzyme in appetite and metabolism regulation. The cannabinoid receptor type 1 (CB1)

Genome-Wide DNA Methylation and Hydroxymethylation Changes Revealed Epigenetic Regulation of Neuromodulation and Myelination in Yak Hypothalamus

open access: yesFrontiers in Genetics, 2021
Both 5-methylcytosine (5mC) and 5-hydroxymethylcytosine (5hmC) are important epigenetic modifications in neurodevelopment. However, there is little research examining the genome-wide patterns of 5mC and 5hmC in brain regions of animals under natural high-
