Objective: to analyze psychological stress factors and salivary cortisol concentration in nursing undergraduates throughout their training.

Method: a cross-sectional, analytical, and comparative study carried out in an evening course using a sociodemographic questionnaire, an Instrument to Assess Stress in Nursing Students, and salivary cortisol analysis. The study included descriptive and comparative analyses and a multiple linear regression model.

The influence of angiotensin II and RAAS blockers on lipolytic and glycolytic activity in isolated adipocytes from Wistar, Wistar-Kyoto and Spontaneously Hypertensive Rats.

The renin-angiotensin-aldosterone system (RAAS) is related to dysfunctional adipose tissue, but the actions of angiotensin II (AII) in adipocytes remains unclear. This study aimed to investigate the effects of RAAS blockers and AII in lipolysis and glycolysis from isolated adipocytes in Wistar (WIS), Wistar-Kyoto (WKY) and Spontaneously Hypertensive Rats (SHR). Adipocytes from 15-weeks-old WIS, WKY and SHR were incubated with AII (10 M to 10 M) and noradrenaline (NOR - 10 M to 10 M) in presence or not of antagonists (Losartan Potassium 10 M, PD 123319 5.

The impact of confinement in the psychosocial behaviour due COVID-19 among members of a Brazilian university.

Background: The current situation due COVID-19 may cause an eminent impact on mental health because the confinement restrictions.

Aims: The aim of this study was to analyze and compare perceived stress, resilience, depression symptoms and coping strategies on the members of University of Campinas, in Brazil, before and during the outbreak of the COVID-19.

Methods: Volunteers over 18 years of both sexes, members of the University of Campinas (Unicamp) in Brazil answered instruments related to perceived stress, depression, resilience and coping strategies during final exams at the end of semester during 2018 to 2020.

The influence of hypertensive environment on adipose tissue remodeling measured by fluorescence lifetime imaging in spontaneously hypertensive rats.

There is a lack of information correlating low adiposity with hypertension experienced by Spontaneous Hypertensive Rats (SHR) or overweight and normotension in Wistar-Kyoto (WKY). We aimed to investigate this lipodystrophy phenomenon by measuring fluorescence lifetime (FLIM), optical redox ratio (ORR), serum levels of hypothalamic-pituitary-adrenal (HPA) and/or hypothalamic-pituitary-thyroid (HPT) hormones axes between Wistar, WKY and SHR before and after establishment of hypertension. Under high blood pressure, we evaluated serum adipokines.

Massage therapy in cortisol circadian rhythm, pain intensity, perceived stress index and quality of life of fibromyalgia syndrome patients.

We investigate the effects of a massage therapy program (MTP) in cortisol concentration (CC), intensity of pain, quality of life and perceived stress index of fibromyalgia patients. Volunteers (n = 24, aged 26-55 years) were treated with MT, twice a week for three months. They answered the Fibromyalgia Impact Questionnaire (FIQ), Perceived Stress Questionnaire (PSQ) and McGill Pain Questionnaire (MPQ-Br), and collected saliva to evaluate CC before and after the end of each month.

History of vascular reactivity models and their involvement in hypertension pathogenesis.

Hypertension is a silent and multifactorial disease. Over two centuries ago, the first device to record blood pressure was developed, making it possible to determine normotension and to establish criteria for hypertension. Since then, several studies have contributed to advance knowledge in this area, promoting significant advances in pharmacological treatments and, as a result, increasing survival of hypertensive people.

Ultrasound associated with caffeine increases basal and beta-adrenoceptor response in adipocytes isolated from subcutaneous adipose tissue in pigs.

Background: The topical use of caffeine has been indicated for the lipodystrophies treatment as it promotes increased lipolysis. Ultrasound (US) is often used in cutaneous diseases, esthetic conditions, and as a skin permeation enhancer.

Objective: We investigate the lipolytic response of adipocytes isolated from subcutaneous adipose pigs tissue subjected to treatment with topical application of phonophoresis associated with caffeine.

Acute and Chronic Effects of Tantric Yoga Practice on Distress Index.

Objectives: To evaluate the acute and chronic effects of yoga practice.

Design: Quantitative study using a one-group pre-posttest design.

Setting: Visão Futuro Institute, Porangaba, São Paulo, Brazil.

Vascular response of ruthenium tetraamines in aortic ring from normotensive rats.

Background: Ruthenium (Ru) tetraamines are being increasingly used as nitric oxide (NO) carriers. In this context, pharmacological studies have become highly relevant to better understand the mechanism of action involved.

Objective: To evaluate the vascular response of the tetraamines trans-[Ru(II)(NH3)4(Py)(NO)](3+), trans-[Ru(II)(Cl)(NO) (cyclan)](PF6)2, and trans-[Ru(II)(NH3)4(4-acPy)(NO)](3+).

[Stress among nurses: an examination of salivary cortisol levels on work and day off].

The present study evaluates the use of salivary cortisol concentration as a physiological index of the stress level among nurses on their work day and day off and correlates it with the questionnaire used to measure occupational stress in nurses (Inventário de Estresse em Enfermeiros - IEE). This is a comparative, cross-sectional descriptive study in which sociodemographic data, IEE results and salivary cortisol levels were used. Fifty-seven nurses participated in the study (80.

The effect of topical caffeine on the morphology of swine hypodermis as measured by ultrasound.

Background: Cellulite or lipodystrophy involves the modification of the subcutaneous adipose tissue. A wide variety of topical products is available to combat cellulite, but these have difficulties in being absorbed through the skin. One option is the therapeutic use of the ultrasound to enhance the trans-dermic transport of these drugs.

Glucocorticoid receptor and Beta-adrenoceptor expression in epididymal adipose tissue from stressed rats.

Adipocytes isolated from epididymal adipose tissue of foot-shock stressed rats are supersensitive to isoprenaline and subsensitive to norepinephrine. These alterations are probably mediated by a stress-induced increase in plasma corticosterone levels. We investigated whether foot-shock stress modifies the expression of glucocorticoid receptors (GRs) and beta-adrenergic protein receptors (beta-ARs) in epididymal adipose tissue from rats submitted to one daily foot-shock session on three consecutive days.

Sensitivity to beta-adrenoceptor agonists of adipocytes from rats treated with an aqueous extract of Croton cajucara Benth.

Aqueous extracts of Croton cajucara bark are used in folk medicine to treat hepatic and gastrointestinal disorders and as a coadjuvant in weight-loss programs. We examined the effect of treating rats for 15 days with a 5% aqueous extract of C. cajucara on body weight and food intake.
