Background Heat is one of the most important physical harmful factors in many work environments. Due to the nature of work, bakery activity is considered as one of the high-risk occupations in terms of heat stress. Therefore, the aim of this study was evaluated of heat exposure in bakery workers using WBGT, HSI and UTCI indices. Methods This study is a descriptive-analytical cross-sectional ...

BACKGROUND The effect of environmental factors and, in particular, non-specific stress on the growth patterns of limbs and other body dimensions of children from past populations is not well understood. AIMS This study assesses whether growth of mediaeval and post-mediaeval children aged between 0-11.5 years from Adriatic (coastal) and continental Croatia varies by region and by the prevalenc...

Inflammatory disorders of the bowel and colon cancer are associated with elevated indices of oxidative stress. Analogous elevations in markers of oxidative stress and loss of cell-membrane integrity are also observed in the colons of rats deficient in vitamin E (D-alpha-tocopherol), the major lipid-soluble antioxidant in biological systems. The causal relationship between colon pathologies asso...

The paperaim of the was to study the effect of low temperature stress on Avena nuda L. seedlings. Cold stress leads to many changes of physiological indices, such as membrane permeability, free proline content, malondialdehyde (MDA) content, and chlorophyll content. Cold stress also leads to changes of some protected enzymes such as peroxidase (POD), superoxide dismutase (SOD), and catalase (CA...

In this paper, a guided wave temperature robust PCA-based stress monitoring methodology is proposed. It is based on the analysis of the longitudinal guided wave propagating along the path under stress. Slight changes in the wave are detected by means of PCA via statistical T 2 and Q indices. Experimental and numerical simulations of the guided wave propagating in material under different temper...

BACKGROUND The effect of eccentric exercise on the time-course changes in several indices of muscle damage and blood oxidative stress was examined. MATERIALS AND METHODS Isometric torque, delayed-onset muscle soreness, creatine kinase, reduced glutathione (GSH), oxidized glutathione (GSSG), thiobarbituric-acid reactive substances (TBARS), protein carbonyls, catalase, uric acid, bilirubin and ...

A new indicator of drought-induced water stress is introduced and applied at the county level in the USA. Unlike most existing drought metrics, we directly consider current daily water demands and renewable daily water supply to estimate the potential stress. Water stress indices developed include the Normalized Deficit Cumulated to represent multiyear droughts by computing the maximum cumulati...

The evolutionary advantages to the suppression of pain during a stressful event (stress-induced analgesia (SIA)) are obvious, yet the reasoning behind sex-differences in the expression of this pain reduction are not. The different ways in which males and females integrate physiological stress responses and descending pain inhibition are unclear. A potential supraspinal modulator of stress-induc...

Previous studies carried out in Euro-American populations have unequivocally indicated that psychological disorders of the CASD (caregivers of children with autism spectrum disorder) are marked with high levels of stress, anxiety, and depression. This finding has been attributed to the reaction of having to care for a child with neurodevelopmental disorders. While there have been reports on aut...

Drought stress is one of the most important abiotic factors which adversely affects growth, metabolism and yield of crops worldwide. The goal of the research was identify drought tolerate canola genotypes using the different drought tolerance indices. The experiment was conducted as split plot based on randomized complete block design with three replications at the experimental farm of agricult...
