original article   introduction: exposure to heat is one of the workplace risk factors, which may lead to thermal strain, such as rising heart rate and body temperature. to have the best association between a heat stress indices and physiological parameters have always been a major concern for those studying the subject. this study aims to compare the association of two heat stress indices with...

BACKGROUND Maximal exercise testing is used in patients with cystic fibrosis to assess functional status and prognosis. The lactate threshold is an index of aerobic fitness with significant advantages over maximal exercise tests. This study was undertaken to determine if the lactate threshold might be identified, non-invasively, in adult patients with cystic fibrosis and mild lung disease by me...

In this thesis, we develop and analyze a simple grey-box model that describes the pathophysiology of central sleep apnea (CSA). We construct our model following a thorough survey of published approaches. Special attention is given to PNEUMA, a complex, comprehensive model of human respiratory and cardiovascular physiology that brings together many existing physiological models. We perform a sen...

The use of a soil fertiliser results in high, good quality yields. most widely used fertilisers are mineral or organic, but there is increasing attention on organomineral produced from sewage sludge. These contain beneficial components which may improve fertility and thus plant productivity, some concerns associated with their application due to composition. Using short-term pot experiment the ...

Obesity is one of the greatest public health challenges of the 21st century. Overweight and obesity drastically increase a person’s risk of developing chronic non-communicable diseases (NCDs), including cardiovascular disease, cancer and diabetes. Furthermore, obesity is already responsible for 2% 8% of health costs and 10% 13% of deaths in several industrialized countries. Lifestyle modificati...

We hypothesized that more complex, i.e. irregular, temporal dynamics and a more interconnected overall network supports greater stability to gas exchange parameters (herein, CO2 net assimilation and transpiration) in plants under water deficit. To test this hypothesis two genotypes of Phaseolus vulgaris were subjected to a period of absence of irrigation, and subsequent rewatering to achieve re...

Background: In this study, the effect of recently popular intermittent fasting on weight loss and role exercise combined with some physiological parameters were investigated. Aim: This study was conducted to investigate alone parameters. Methods: A total 36 healthy individuals between 20 24 years age, including 18 in experimental group (exercising) control (non-exercising), who assigned by rand...

Naturally plants exposed with many adverse environmental conditions like biotic and a biotic stress. Despite all others stresses heavy metal stress is one of great importance which has a notable adverse effects on crop productivity and growth, heavy metal stress triggers different responses in plants, ranging from biochemical responses to crop yield. Understanding the biochemical and molecular ...

A field experiment was established in a second-growth hardwood forest dominated by red oak (Quercus rubra L.) to examine the effects of shelterwood overstory density on leaf gas exchange and seedling water status of planted red oak, naturally regenerated red oak and sugar maple (Acer saccharum Marsh.) seedlings during the first growing season following harvest. Canopy cover of uncut control sta...
