any form of industrialization leads to cultural changes which may be rapid and extensive, and provoke considerable stress. such changes are particularly extensive when developing countries are rapidly industrialized. agricultural workers who move to industrial areas may shift from barter to a monetary economy. all of this is to them an entirely new way of living and so they try to keep contact ...

Fluctuating asymmetry (FA) represents non-directional deviations from perfect symmetry in morphological characters. Prenatal stressors contribute to the imprecise expression of symmetrical phenotypes and display of agonistic behavior in children and adults. Because prenatal stress affects neurological function and overt behavior, and FA is often used as a marker for prenatal stress, we hypothes...

Occupational stress is universally experienced and is emerging as a major risk factor for physical and mental illness and a key factor in poor work performance and low job satisfaction. However, the technology does not currently exist to unobtrusively measure occupational stress in real-time. Here, we describe the design and clinical validation of an automated high-definition thermal imaging sy...

Background: In light of recent evidence suggesting the presence of stress processing deficits in stimulant users, coupled with laboratory studies demonstrating an association between stress reactivity and relapse to stimulant use, interventions that target stress-induced craving and stress reactivity may reduce relapse risk in this population. Objective: This study examines changes in stress re...

Evidence that the swine lungworm can serve as reservoir and intermediate host for the hog cholera virus has been presented. The virus, however, is ordinarily carried in a masked form and must be provoked to pathogenicity by some stress before it can cause apparent disease. In the present experiments, ascaris larvae supplied the provocation needed to induce hog cholera in swine carrying lungworm...

BACKGROUND Vasospastic angina (VA) can occasionally cause acute myocardial infarction (AMI). METHODS AND RESULTS From January 2003 to June 2005, coronary spastic angina was diagnosed in 292 patients by performing spasm provocation tests. Among the 292 patients, 21 (7.2% of all the VA patients) had an AMI. There were 20 patients who initially visited the emergency room for AMI without sufferin...

BACKGROUND Autoimmune thyroid disease (ATD) has been occasionally observed in patients with primary adrenal insufficiency (PAI). In contrast, less than 20 cases of comorbid PAI with ATD have been found in the English literature. One conceivable reason is difficulty in detecting latent PAI. OBJECTIVE Information of clinical presentation and diagnostics is sought to facilitate diagnosis of late...

The ability to reproduce chest pain and to identify the esophagus as the source of this pain are the major reasons why provocation testing has become standard in the evaluation of patients with noncardiac chest pain. Recent studies that challenge the validity of performing provocation tests have polarized experts into two camps: those who would abandon such testing because of its low sensitivit...

BACKGROUND Despite a nonobstructive coronary angiogram, many patients may still have an abnormal coronary vasomotor response to provocation and to myocardial demand during stress. The ability of noninvasive stress tests to predict coronary vasomotor dysfunction in patients with nonobstructive coronary artery disease is unknown. METHODS AND RESULTS All patients with nonobstructive coronary art...
