Stress-Induced Release of Eating Related Hormones in Young Women Classified as Restrained Eaters

Eating related hormones may be strongly involved in the control of food intake under stressful conditions. The development and maintenance of eating disorders such as obesity, binge eating disorder, and bulimia nervosa might be in part explained by the altered release of insulin, ghrelin or leptin in particular in vulnerable subjects such as restrained eaters. The present investigation describes the secretion of these hormones before and after stress in a sample of 44 young women, who were selected according to a high degree of dietary restraint. Hormones were analysed from blood samples which were drawn 30 and 60 minutes after a validated stressor. Ghrelin levels significantly rise after stress induction. Insulin and Leptin both significantly fall after stress. The results are discussed with regard to biological as well as psychological causes and consequences of stress related hormone release in restrained eaters.

Mental Health Distress and Wellness among Medical Students

The aim of this article was to assess the mental distress more extensively than has been done before and to determine likely predictors of distress and well-being issues. Moreover, the significant improvement needed in connection to medical students in the context of psychological signs, symptoms of mental distress, and solutions for the students with mental health distress and wellness perspectives were addressed.

Stress Induced Cortisol Response in Young Women Classified as Restrained and Unrestrained Eaters

Dietary restraint has been hypothesized to be a risk factor to develop disordered eating behavior with the consequence of clinical eating disorders such as bulimia nervosa or binge eating disorder. Because of mostly unsuccessful dieting efforts restrained eaters are supposed to suffer from stress, indicated by a higher cortisol response. The present investigation tested this hypothesis in 41 subjects undergoing a laboratory stress test with the measurement of salivary cortisol. The results show lower stress induced cortisol in the restrained eaters. This is discussed with regard to a possibly dysregulated intake behavior in restrained eaters.

Neurobiochemical Roles of Low Molecular Weight Antioxidants on Oxidative Stress Biomarkers and Severity of Ischemic Stroke in Wistar Rats

Purpose: To evaluate the neurobiochemical role(s) of low molecular weight (LMWA) antioxidants in the treatment of surgically- induced ischemic stroke (IS) in wistar rats.Methods: Ischemic stroke was induced in wistar rats using middle cerebral artery occlusion (MCAO). Neurological assessments were carried out using stair case, cylinder test and modified neurological severity score (mnss) methods. Low molecular weight antioxidants (vitamins C, E, α-lipoic acid, dimethyl sulfoxide and mannitol) were orally administered to the rats for two weeks in three different doses (22.5, 45 and 67.5 mg/kg).

Stress-Induced Laboratory Eating Behavior in Obese and Normal-Weight Women

Inconsistent results of stress induced eating behavior in obesity have been reported. In order to describe the effect of stress on eating behavior in detail, we investigated microstructural aspects of food intake in a controlled laboratory experiment. Eating behavior of 43 obese women and 42 normal weight controls between 18 and 30 years was assessed twice (one time after participating in the Trier Social Stress Test and one time after a control session). A universal eating monitor was used to obtain cumulative intake curves with pudding as laboratory food. Compared to controls, obese showed inhibited eating behavior after stress. The results are interpreted and discussed with regard to restrained eating.

Mitochondrial Production of Perhydroxyl Radical (HO2 • ) as Inducer of Aging and Age-Related Pathologies

All organisms age, in the search of the universal mechanisms of aging Barja analyzed results obtained with various species of mammals and birds and concluded that only two known factors correlate in the right sense (inversely) with animal longevity in vertebrates: the long life span is associated with (a) low rates of mitochondrial reactive oxygen species production, and (b) low degree of fatty acid polyunsaturation of cellular membranes including the mitochondrial ones [Barja (2014) Prog Mol Biol Transl Sci. 127:1-27].

A Study on Perceived Stress among Undergraduate Medical Students of Bahir Dar University, Bahir Bar, North West Ethiopia, 2016: Institutional Based Cross Sectional Study

Tertiary education has always been regarded as highly stressful environment to students. Medical and health science training further add to the already stressful environment. Awareness of the existence of stress in medical students by physicians will help in diminishing student’s experience of stress. Therefore, identifying additional stressors in the clinical context is very crucial for providing measures to minimize students’ stress to a tolerable level and helping them to cope better. And the aim of this study is to assess perceived stress and factors associated with it among Bahir Dar University medical students, North West Ethiopia, 2016.

Primary Angiitis of the Central Nervous System a Riddle, Wrapped in a Mystery, inside an Enigma

54-year-old gentleman with a previous medical history consistent of recurrent headaches, hypertension, dilated cardiomyopathy, hypercholesterolemia and recurrent renal calculi. Over a one-year period, he gradually developed worsening headaches associated with intermittent blurred vision, generalized aches and pains, mild cognitive impairment, and several episodes of focal upper and lower limb weakness.

Hemodynamic and Autonomic Reactivity to Mental and Physical Stress in Lean, Overweight and Obese Subjects

There could be progressive changes in hemodynamic and autonomic parameters causing cardiovascular damage from lean to morbid obesity. We aim to study resting and reactivity of hemodynamic and autonomic parameters to physical and mental stress in lean, overweight and obese subjects of the Oman Family Study (OFS).

The Role of Nutrition in Fighting Free Radicals

This paper aims to review in literature the main mechanisms of oxidative stress, pointing out the major formed metabolites, the mechanisms of cell damage and major antioxidants. Oxygen is essential to human life. The formation of free radicals (FR) is closely related to oxygen consumption, a mechanism that occurs with an incomplete reduction of this molecule.

Epigenetic Changes Caused by Occupational Stress in Humans Revealed through Noninvasive Assessment of DNA Methylation of the Tyrosine Hydroxylase Gene

Tyrosine hydroxylase (TH) catalyzes the rate-limiting step in the synthesis of L-dihydroxyphenylalanine (L-DOPA), a precursor of dopamine, and is considered to be involved in many aspects of mental health. On the other hand, the epigenetic mechanisms have been recognized as mediators of stable changes in brain function.
