Unraveling the Interaction Between Beige Adipocytes and the Sympathetic Nervous System
… to be activated by external stimuli such as the sympathetic nervous system to drive thermogenesis. Recent studies have shown that active beige adipocytes can increase energy expenditure and are associated with anti-obesity and anti-diabetes effects in mice and humans. However, the origin of beige …

Sympathetic nervous system in the development of mild DOCA-salt hypertension
… compelling evidence for a role of the central nervous system in long-term regulation of arterial pressure, primarily by modulating sympathetic nerve activity. Sympathetic nervous system activation contributes to the pathogenesis of human hypertension. Recent evidence points to …

Influence of osteopathic palpatory examination on sympathetic nervous system function: a pilot study
… of osteopathic palpatory examination on sympathetic nervous system function. Fourteen participants (6 male and 8 female volunteers, age range 20-23 years) completed this study. An osteopathic screening examination of the thoracic spine, involving the assessment of the active, passive, …

Sympathy for the Microbiota: How Changes in Gut Microbial Composition Influence the Immune System and Basic Physiology by Way of the Sympathetic Nervous System
… reservoir as well as a complex and autonomous nervous system. The GI tract is continuously exposed to foreign antigen and potentially toxic chemicals through the ingestion of food. In addition, the lumen of the human GI tract is populated with approximately 1013 bacteria, which is equivalent to …

QT-interval adaptation to changes in autonomic balance
… as it relates to the influence of the autonomic nervous system on the heart, is primarily studied via frequency-domain and time-domain analysis of heart rate variability (HRV). HRV studies the variability of the RR intervals in the ECG; these intervals are modulated by the autonomic influence on …

Differences in sympathetic nervous response due to gender
The sympathetic nervous system, in addition to its many roles as part of the autonomic nervous system, utilizes contact with many organs in the body to recruit them for an immediate response to danger. The multiple survival responses that the sympathetic nervous system manifests are typically known …

The Role of Gata3 in Blood Stem Cell Emergence
… Gata3 plays a dual role in the development of sympathetic nervous system and haematopoietic system. In fact, Gata3 has proven to be crucial for the production of HSCs through regulation of catecholamine production from the co-developing sympathetic nervous system. Also, it was recently shown …

Lateralized Induction of Cardiovascular Responses: Exploring Asymmetric Autonomic Regulation
There is clear evidence that the autonomic nervous system (ANS) is lateralized at both the peripheral as well as the central levels of the nervous system. Both the vagus and the sympathetic ganglia asymmetrically innervate the sino-atrial node and the myocardium of the heart. This lateralization …

The effects of slow rib raising on heart rate, blood pressure, respiration rate and pain pressure threshold
… can produce positive outcomes involving the sympathetic nervous system, however supporting evidence remains scarce. This minor thesis was written by a post-graduate student as part of the requirements of the Master of Health Science (Osteopathy) program.

Altered Autonomic Nervous System Function in Chickens Divergently Selected for Body Weight
Autonomic nervous system activity is related to body weight regulation. Based on the MONA LISA hypothesis it has been suggested that most obese subjects and animals have low sympathetic nervous system activity. The aim of this study was to investigate whether there are differences in autonomic …

Notch Signaling in Neuroblastoma and Renal Cell Carcinoma
… is an embryonal tumor derived from cells of the sympathetic nervous system, arrested at an immature stage of differentiation. Notch signaling is thought to play an important role during the development of the sympathetic nervous system, and prior studies have indicated that dysregulated Notch …

ABSENCE OF V1AR ALTERS CARDIAC FUNCTION AT BASELINE AND FOLLOWING ACUTE CARDIAC INJURY
… responses to the decrease in cardiac output and systemic blood pressure, such as the activation of the renin-angiotensin-aldosterone system (RAAS) and the sympathetic nervous system. Current treatment guidelines recommend using drugs that block β-adrenergic receptor (βAR) signaling (e.g. β- …

The aim of the present study was to evaluate the relationship between sleep deprivation and the autonomic nervous system activity by means of heart rate variability (HRV) and blood pressure variability (BPV). All …

The Efficacy of Acupuncture Versus Non-Penetrating Sham Acupuncture in Relieving Delayed Onset Muscle Soreness (DOMS) in Healthy Human Adults
… and perfusion (BF) were recorded to quantify the sympathetic nervous system response to treatment. The ACU group showed a significant increase in ipsilateral BF and in bilateral SC. The ACU group showed a significant decrease in distal ST bilaterally. The ACU and S-ACU groups showed decreased …

Microdialysis to study the Gastrin-ECL cell Axis in the conscious rat
… We also examined whether the vagus and the sympathetic nervous system contributes to the food- and gastrin-evoked responses of ECL cells in situ. The results suggest that vagal activation does not stimulate histamine mobilization by a direct action on the ECL cells. Instead, the ECL cells …

Sleep under stress: the complex web of fear, hypervigilance and mental health in a low socioeconomic status community in South Africa
… is typically characterized by heightened sympathetic nervous system activity and reduced parasympathetic tone, which can be quantified through measures of autonomic nervous system function, such as heart rate variability. Heart rate variability (HRV) is a non-invasive measure of autonomic …
