Hormone Regulation of NPY Neuron Activity in the Arcuate Nucleus of the Hypothalamus
Neuropeptide Y (NPY)-expressing neurons in the arcuate nucleus of the hypothalamus are part of a neuroendocrine feedback loop that regulates feeding behavior and glucose homeostasis. NPY neurons sense peripheral signals of energy stores, including the hormones leptin, insulin, and ghrelin, and …

Changes in NPY staining in the arcuate nucleus during and after food restriction in lactating rats
… on Neuropeptide Y (NPY) staining in the arcuate nucleus of lactating rats to evaluate a role for NPY in the maintenance of lactational diestrus in food restricted rats. NPY staining was compared on days 15, 20 and 25 of lactation between animals fed ad libitum (AL) and animals food …

The role of notch signaling in the development of the hypothalamic-pituitary axis and arcuate nucleus
… changes in the development of the hypothalamic arcuate nucleus (Arc), found within the anterior hypothalamus. The Arc contains proopoiomelanocortin (POMC), neuropeptide Y (NPY) and growth hormone releasing hormone (GHRH) neurons, which regulate feeding, energy balance and body size. …

Brain Connectivity in Autism Spectrum Disorder
… white matter association tracts, such as the arcuate and uncinate fasciculus, known to be important for language and social cognition.<br/>A second step consisted in the tractography analysis of limbic and cerebellar tracts in a small pilot study. Our findings confirmed differences in the the …

The relationship between plate curvature and elastic plate thickness : a study of the Peru-Chile Trench
… would be reduced for trenches that are highly arcuate in map view, again due to inelastic yielding. If such a relationship exists, the effect for oceanic lithosphere is much smaller than what is documented for continental plates where they underthrust highly arcuate fold belts.

Alteration of bone metabolism in OLETF rat
… from 40wks of age. OLETF rat hypothalamic arcuate neuron cell NPY2 receptor were strongly pattern expressed than LETO rat. OLETF rat testosterone was decreased in 25wks and significantly lower in 40 and 52wks (p<0.05); serum leptin and IGF-I levels were higher (p<0.05) in whole time; …

A prefrontal source of visual target enhancement in the macaque area V4
The ventral pre-arcuate area (VPA) in the primate prefrontal cortex has recently been found to play an important role in feature-based selection of visual targets in the context of a naturalistic free-gaze visual search task. While VPA neuronal activation was found to be necessary for behavioral …

Hypothalamic control of energy rheostasis during metabolic challenges, pregnancy, and lactation
… and decreases POMC neuron activity in the arcuate nucleus. Chemogenetic activation of POMC neurons or inhibition of AgRP neurons suppressed pregnancy-induced feeding, indicating that these changes are required for gestational hyperphagia. Spatial transcriptomic profiling, using in situ …

Experimental and seismological constraints on the rheology, evolution, and alteration of the lithosphere at oceanic spreading centers
… Ridge delineate for the first time the arcuate, subsurface structure of a long-lived, active detachment fault. This fault penetrates the entire oceanic crust and forms the high-permeability pathway necessary to sustain long-lived, high-temperature hydrothermal venting in this region. …

Transcriptomic Profiling of Hypothalamic Kiss1 Neurons
… regulation of gonadotropin secretion: the arcuate nucleus (ARC) and the anteroventral periventricular nucleus (AVPV). The two populations play distinct physiological roles in the HPG axis. Arcuate Kiss1 neurons have been implicated in the integration of various endogenous and environmental …

Loss of Ventromedial Hypothalamic Leptin Receptors Results in Increased Adiposity and a Metabolic Syndrome
… much work has focused on leptin's actions in the arcuate nucleus, other sites have received substantially less attention. Here, I report that mice lacking leptin receptors within the ventromedial hypothalamic nucleus (Lepr KOVMH) develop increased adiposity and a metabolic syndrome. Lepr KOVMH …

Effects of exogenous and endogenous factors on appetite regulation in broiler chicks and Japanese quail
… fewer times than control birds. Within the arcuate nucleus (ARC) there was an increase in c-Fos immunoreactivity, indicating neuronal activation, in FA-treated chicks. Within the hypothalamus, there was a decrease in mRNA abundance of galanin, ghrelin, melanocortin receptor 3, and …

Satiety induced by neuropeptide FF and gastrin in birds

Restriction of Food Intake by Dorsomedial Hypothalamus
… activity of AGRP neurons and POMC neurons in the arcuate nucleus and neurons in other brain regions. In these dissertation, I will describe how we identify novel neuronal populations that are regulated by leptin directly or indirectly. In order to identify novel sites of leptin action, we used …

Entwicklung einer simultanen refraktions- und reflexionsseismischen 3D-Laufzeittomographie mit Anwendung auf tiefenseismische TRANSALP-Weitwinkeldaten aus den Ostalpen
… method. Accuracy was adjusted by several means: arcuate ART trajectories are roughly adjusted to the velocity field before bending, multiple ART travel time minima are perturbed and step length along the ray path for distant observations is reduced by iterative resegmentation. The resulting ray …
