Comparison of the effects of Truview PCD™ video laryngoscopy and Macintosh blade direct laryngoscopy in geriatric patients

To compare the effects of Truview PCD™ video laryngoscopy (TVL) and Macintosh blade direct laryngoscopy (MDL) on hemodynamic responses observed during laryngoscopy and orotracheal intubation conditions in geriatric patients.

Objective: To investigate the effect of prolotherapy on pain and shoulder range of motion in stroke patients with hemiplegic shoulder pain due to rotator cuff tendinopathy. Methods: The data of 10 patients (mean age, 64.2±11.6 years) who had a history stroke of more than six months and underwent prolotherapy treatment were collected retrospectively. The treatment included 3 sessions of dextrose prolotherapy injections applied to rotator cuff tendon. Visual analogue scale pain scores and shoulder range of motions measured at baseline and two weeks later after end of the treatment were assessed. Results: Visual analogue scale shoulder pain scores of the patients decreased from 8.2±1.1 at baseline to 4.8±1.9 after prolotherapy (p=0.030). The degrees of shoulder flexion and abduction increased significantly after the treatment (p

Reactive oxygen species derived from NAD(P)H oxidase play a role on ethanol-induced hypertension and endothelial dysfunction in rat resistance arteries

Abstract

Chronic ethanol consumption is a risk factor for cardiovascular diseases. We studied whether NAD(P)H oxidase-derived reactive oxygen species (ROS) play a role in ethanol-induced hypertension, vascular dysfunction, and protein expression in resistance arteries. Male Wistar rats were treated with ethanol (20 % v/v) for 6 weeks. Ethanol treatment increased blood pressure and decreased acetylcholine-induced relaxation in the rat mesenteric arterial bed (MAB). These responses were attenuated by apocynin (30 mg/kg/day; p.o. gavage). Ethanol consumption increased superoxide anion (O2) generation and decreased nitrate/nitrite (NOx ) concentration in the rat MAB and apocynin prevented these responses. Conversely, ethanol did not affect the concentration of hydrogen peroxide (H2O2) and reduced glutathione (GSH) or the activity of superoxide dismutase (SOD) and catalase (CAT) in the rat MAB. Ethanol increased interleukin (IL)-10 levels in the rat MAB but did not affect the levels of tumor necrosis factor (TNF)-α, IL-6, or IL-1β. Ethanol increased the expression of Nox2 and the phosphorylation of SAPK/JNK, but reduced eNOS expression in the rat MAB. Apocynin prevented these responses. However, ethanol treatment did not affect the expression of Nox1, Nox4, p38MAPK, ERK1/2, or SAPK/JNK in the rat MAB. Ethanol increased plasma levels of TBARS, TNF-α, IL-6, IL-1β, and IL-10, whereas it decreased NOx levels. The major finding of our study is that NAD(P)H oxidase-derived ROS play a role on ethanol-induced hypertension and endothelial dysfunction in resistance arteries. Moreover, ethanol consumption affects the expression and phosphorylation of proteins that regulate vascular function and NAD(P)H oxidase-derived ROS play a role in such responses.

The role of personality in dyadic interaction: A psychophysiological study

Publication date: November 2016
Source:International Journal of Psychophysiology, Volume 109
Author(s): Mikko Salminen, Pentti Henttonen, Niklas Ravaja
Psychophysiological activity was recorded during development discussions of 44 manager-subordinate pairs to examine the effects of the Big Five personality traits Extraversion and Conscientiousness, and personality similarity during dyadic social interaction. Facial electromyography and frontal electroencephalography (EEG) asymmetry were collected continuously during the 30-min discussions. Different actor and partner effects and Actor×Partner interactions were observed. Matching levels of Extraversion led to higher periocular muscle activity, indicating positive valence emotional expressions. The results are discussed considering similarity attraction theories.
