Focusing attention on biological markers of acute stressor intensity: empirical evidence and limitations. NEUROSCIENCE AND BIOBEHAVIORAL REVIEWS. The availability of biological markers that objectively quantify stress is a highly relevant issue. However, experimental evidence suggests that most physiological changes elicited by emotional stressors do not reflect their intensity and are not useful for this purpose. Thus, we review experimental evidence in animals and humans about the putative validity of neuroendocrine and sympathetic/parasympathetic variables to measure stress. Plasma levels of some hormones (e.g. ACTH, glucocorticoids, prolactin and catecholamines) have been found to reflect, at least under certain conditions, the intensity of emotional stressors in animals and probably in humans. However, the temporal resolution of hormone changes is insufficient to reflect the very dynamic psychological processes taking place while experiencing stressors. Cardiovascular parameters (e.g. heart rate and blood pressure) have much better temporal resolution but their validity as markers of stressor intensity either in animals or humans is problematic. Skin conductance and pupil dilation appear to be promising. Additional and more systematic studies are needed to demonstrate the actual va...

The objective of the study was to compare the results of caloric reflex tests and video head impulse tests (vHITs) of lateral semicircular canals (SCCs).MethodsPatients aged over 18  years diagnosed with definite Ménière’s disease (MD) according to the AAO–HNS 1995 criteria were recruited. Audiological tests, caloric tests and vHITs were conducted on all participants. A caloric weakness (canal paresis) of >  25% was considered significant. A VOR gain of

In this study, we develop a wearable pressure sensing device to quantitatively measure the elicited palmar grasp strength of clinically complicated neonates aged 0 to 2 months. A capacitive pressure sensing device was fabricated using Ecoflex which acts as a dielectric material sandwiched between two copper electrodes, and further assembled with the coupling parts to provide comfort to neonates. The characterization of the fabricated device showed a linear sensitivity (0.13kPa-1), a high pressure range up to 530 kPa, and excellent working stability. Clinical experiments were performed on 33 newborns by investigating...

AbstractObjectiveTo investigate the possible role of serum norepinephrine (NE), leptin and 5 ‐hydroxytryptamine (5‐HT) and their correlations with sympathetic skin response located in the penis (PSSR) in primary premature ejaculation (PPE).MethodsWe compared the serum level of NE, leptin and 5 ‐HT, Intravaginal ejaculatory latency time(IELT) and The Premature Ejaculation Diagnostic Tool (PEDT) scores between 57 PPE patients and 42 healthy control men as controls, who were recruited between September 2016 and January 2019. Additionally, the amplitude and latency of PSSR were measured and compared between the two group...

ON THE NATURE OF HIGH-AMPLITUDE PROPAGATING PRESSURE WAVES IN THE HUMAN COLON. Am J Physiol Gastrointest Liver Physiol. 2020 Feb 18;: Authors: Milkova N, Parsons SP, Ratcliffe E, Huizinga JD, Chen J Abstract Characterization of High-Amplitude Propagating Pressure Waves (HAPWs or HAPCs) plays a key role in diagnosis of colon dysmotility using any type of colonic manometry. With the introduction of high-resolution manometry, more insight is gained into this most prominent propulsive motor pattern. Here we employ a water-perfused catheter with 84 sensors with intervals between measuring points of 1 cm th...

Tear fluid secreted from the exocrine lacrimal gland (LG) has an essential role in maintaining a homeostatic environment for a healthy ocular surface. It is known that tear secretion is regulated by both the sympathetic and parasympathetic components of the autonomic nervous system, although the contribution of each component is not fully understood. Here, to investigate LG innervation, we identified sympathetic and parasympathetic postganglionic nerves, specifically innervating the mouse LG, by injecting a retrograde neuronal tracer into the LG.

ConclusionIn our study, both CR and PE prevented age-related changes in the corpus cavernosum of rats. Reducing nitrosative damage in the neurovascular structure was the main mechanism. CR and exercise restored the endothelial and smooth muscle cells in corpus cavernosum by decreasing apoptosis. The mechanism of enhancing functional response in corpus cavernosum with CR was the improvement of endothelial function via eNOS activation however it involves increases in the NO-cGMP signaling pathway by an endothelium-independent mechanism with PE. This might be a direct stimulation of smooth muscle cells by NO, which released f...

ConclusionsButyrate is effective in promoting peristalsis, but only when the level of colonic activity is low such as under conditions of low intraluminal pressure. This suggests that it may play a significant role in patients with poor fiber intake, where there is low mechanical stimulation in the lumen.

In Iranian traditional medicine, plants belonging to Inula genus have been used for the treatment of seizure. We decided to investigate the anticonvulsant activity of seven species from this genus to find an effective remedy for seizure with less adverse effects compared to available medicines. Aqueous and methanolic extracts of Inula britannica, Inula helenium, Inula viscidula, Inula oculus-christi, Inula aucheriana, Inula thapsoides and Inula salicina were prepared and their antiepileptic activity was investigated by maximal electroshock and pentylentetrazole tests. Diazepam was used as positive control in both tests. Tw...
