It has long been known that the central nervous system (CNS) directly affects pancreatic insulin release. This study was undertaken to determine the effect of the CNS on pancreatic insulin release in three-month-old female lean (Fa/Fa) and hyperinsulinemic obese (fa/fa) Zucker rats. Chloral hydrate

Obesity is known to alter various physiological parameters including the pain sensitivity. There are conflicting reports on the pain sensitivity in obesity. In this context, the present study was aimed to investigate the tonic pain response in obese rabbit model. To achieve this aim, two groups of

OBJECTIVE Obese children demonstrate less activation in prefrontal regions associated with self-control and inhibition when presented with food cues and advertisements. This study evaluates the differences between obese and healthy weight children in resting-state functional connectivity to these

A large body of clinical investigation implicates an important role for the sympathetic nervous system in linking obesity with hypertension. However, the experimental support for this hypothesis is derived from strictly white cohorts. The goal of this study was to determine whether being overweight

Obese Zucker rats have a narrower and more collapsible upper airway compared with lean controls, similar to obstructive sleep apnea (OSA) patients. Genioglossus (GG) muscle activity is augmented in awake OSA patients to compensate for airway narrowing, but the neural control of GG activity in obese

Primary aging in adult humans is associated with a progressive, tonic activation of the peripheral sympathetic nervous system (SNS). The purpose of this SNS activation and its physiological impact are, however, unknown. We hypothesize that the chronic stimulation of the SNS with aging is driven in

The mechanisms involved in brown adipose tissue (BAT) atrophy in obese rats were investigated. In urethan-anesthetized adult obese (fa/fa) and lean (Fa/?) rats, colonic temperature (Tc), interscapular BAT (IBAT) temperature (TIBAT), and the TIBAT-Tc gradient were measured after microknife cut in the

Transswitching is a variant of classical conditioning that entails the use of tonic stimuli of relatively long duration in addition to briefer, phasic stimuli which are paired or not paired with the unconditioned stimulus. The same conditioned stimulus can be conditioned to different conditioned

This study aimed to establish mechanistic links between the prolonged intake of desloratadine, a common H1 receptor blocker (i.e. antihistamine), and development of obesity and metabolic syndrome. Male Sprague-Dawley rats were treated orally for 16 weeks with desloratadine. We analyzed the dynamics

ANG II applied to the interstitial space influences carbohydrate and lipid metabolism in a tissue-specific fashion. Thus endogenous ANG II may have a tonic effect on tissue metabolism that could be reversed with ANG II type 1 (AT1) receptor blockade, particularly during adrenergic stimulation. We

Obese Zucker rats (OZR) have elevated sympathetic nerve activity (SNA) and mean arterial pressure (MAP) compared with lean Zucker rats (LZR). We examined whether altered tonic glutamatergic, angiotensinergic, or GABAergic inputs to the rostral ventrolateral medulla (RVLM) contribute to elevated SNA

Agouti-related protein (AgRP) is an orexigenic (appetite stimulating) neuropeptide suggested to exert tonic control over long-term energy balance. While some have speculated AgRP is not involved in the episodic (i.e. meal to meal energy intake) control, acute decreases in plasma agouti-related

The aim of this study is to look for correlation between a physiological variable (skin conductance, SCL) and cognitive variables (reaction time, RT and productivity score) obtained in a memory task. Subjects were 17 females, including 7 patients and 10 controls. Patients were recruited among women

Melanocortin-4 receptor (MC4-R) density is thought to be regulated by synaptic availability of endogenous agonist, alpha-melanocyte-stimulating hormone (alpha-MSH), and also by agouti-related protein (AGRP), which acts as a competitive antagonist. As hypothalamic MC4-R have been implicated in the
