AbstractCocoa (Theobroma cacao L.) is an important cash crop in many tropical countries, particularly in West Africa. Heat and drought are both known to affect the physiology of cocoa plants through reduced rates of photosynthesis and transpiration, as well as changed physiological processes such as the functions of photosystems, chlorophyll synthesis, stomatal conductance and expression of heat-shock proteins. This in turn leads to decreased yields and increased risks of mortality under severe heat and drought. To help cocoa plants adapt to climate change, the literature suggests agroforestry as a potential farm management practice. It has been argued that the lack of tree cover in cocoa cultivation systems exposes the crop to heat and direct solar radiation, thus increasing evapotranspiration and the risk of drought. Drawing on data generated from two on-field studies, this chapter assesses the shade effect on cocoa’s physiological responses to drought and heat stress to determine whether shade would be beneficial under climate change scenarios. We conclude that shade improves the physiology of cocoa, but that this may not be sufficient to compensate for the negative effects of high temperatures and severe drought exacerbated by climate change in sub-optimal conditions.

AbstractMist spraying is an active cooling technology to alleviate heat stress during hot summers. There is no clear conclusion as to when mist spray should be used and its cooling potential in hot-humid regions yet. A periodic mist spraying system was set up, and environmental measurements coupled with questionnaire surveys were conducted, investigating the dynamic effect of spraying on the micro-environment and thermal perception. The results showed that elevated ambient temperatures could lead to a more substantial cooling impact, with a maximum cooling value of 5.68 ℃. The increase in thermal comfort due to the mist outweighed the decrease in thermal sensation. The study indicated that the mist spray system should be activated if the ambient temperature reached 32.5 ℃. Spraying could help local residents maintain a physiological state close to slightly hot and neutral comfort when the ambient temperature exceeded 34℃. The findings provide valuable guidance for the application of mist spray system in practical engineering scenarios in hot-humid areas.

Abstract Cotton, being a leading commercial fibre crop, is grown on 20.5 million hectares in three major cotton-producing countries: China, India and Pakistan. Wide differences in yield per hectare exist among these countries and these are being aggravated by changing climate conditions, i.e. higher temperatures and significant seasonal and regional fluctuation in rainfall. Pakistan is one of the countries most affected by climate change. The disastrous effects of extreme periods of heat stress in cotton were very prominent in Pakistan during the growing seasons 2013-2014 (40-50% fruit abortion) and 2016-2017 (33% shortfall), which posed an alarming threat to the cotton-based economy of Pakistan. Poor resilience of the most commonly grown cotton varieties against extreme periods of heat stress are considered to be major factors for this drastic downfall in cotton production in Pakistan. Using the approach of induced mutation breeding, the Nuclear Institute for Agriculture and Biology (NIAB), Faisalabad, Pakistan, has demonstrated its capabilities in developing cotton mutants that can tolerate the changed climatic conditions and sustain high yields under contrasting environments. The results of studies on the phenological and physiological traits conferring heat tolerance are presented here for thermo-tolerant cotton mutants (NIAB-878, NIAB-545, NIAB-1048, NIAB-444, NIAB-1089, NIAB-1064, NIAB-1042) relative to FH-142 and FH-Lalazar. NIAB-878 excelled in heat tolerance by maintaining the highest anther dehiscence (82%) and minimum cell injury percentage (39%) along with maximum stomatal conductance (27.7 mmol CO2/m2/s), transpiration rate (6.89 μmol H2O/m2/s), net photosynthetic rate (44.6 mmol CO2/m2/s) and physiological water use efficiency (6.81 mmol CO2/μmol H2O) under the prevailing high temperatures.

AbstractwIRA has been shown to reduce chlamydial infections in vitro and in vivo and might therefore offer an innovative therapeutic approach for fighting trachoma. However, since the eye is a highly temperature- and radiation-sensitive organ, a safety assessment of the ocular structures affected by wIRA treatment is required to establish wIRA as a potentially successful treatment option for clinical application. A prerequisite for this is to demonstrate that wIRA does not have adverse side-effects such as inducing a non-physiological temperature increase which causes cell stress and damage to ocular tissues and which, in turn, is ultimately associated with impaired vision. Likewise, the potential negative impact of non-thermal photochemical effects of wIRA irradiation needs to be investigated. Data from our ex vivo studies in pig and mouse models, as well as in vivo data in a guinea pig model, provide good evidence for the safe use of wIRA to treat chlamydial infections. These studies have excluded a non-physiological temperature rise as well as the activation of heat and stress-induced proteins after wIRA irradiation with therapy-relevant irradiances. Nevertheless, additional detailed in vitro and in vivo studies are needed to further advance the clinical use of wIRA.

Brain temperature control is important in clinical therapy, because moderate temperature reduction of brain temperature increases the survival rate after head trauma. A factor that affects the brain temperature distribution is the cerebral blood flow, which is controlled by autoregulatory mechanisms. To improve the existing thermal models of brain, we incorporate the effect of the temperature over the metabolic heat generation, and the regulatory processes that control the cerebral blood perfusion and depend on physiological parameters like, the mean arterial blood pressure, the partial pressu

Many biological studies, drug screening methods, and cellular therapies require culture and manipulation of living cells outside of their natural environment in the body. The gap between the cellular microenvironment in vivo and in vitro, however, poses challenges for obtaining physiologically relevant responses from cells used in basic biological studies or drug screens and for drawing out the maximum functional potential from cells used therapeutically. One of the reasons for this gap is because the fluidic environment of mammalian cells in vivo is microscale and dynamic whereas typical in v

Heat shock proteins (Hsp), also called chaperones, are proteins that are indispensable for the proper formation of the polypeptide chain; and have a role in its translocation within the cell. Hsp70 in cells helps to re-establish the native conformation of proteins that have denatured under the influence of various stressogens, by preventing their aggregation, which results in protecting the cell from apoptosis and having an anti-inflammatory effect. These proteins are classified on the basis of molecular mass, and the most significant is heat shock protein 70 (Hsp70) with a molecular mass of a

A new mathematical multi-segmented model based on an improved Stolwijk model is developed for predicting nude human thermal and regulatory responses within body segments and the environment. The passive model segments the body into the 15 cylindrical parts. Each body part is divided into four nodes of core, skin, artery blood, and vein blood. The body nodes interact with each other through convection, perfusion and conduction. In any body element, the blood exiting the arteries and flowing into the capillaries is divided into blood flowing in the core (exchanges heat by perfusion in the core)

Heat stress can be defined as a condition in which there is a changed relationship in the amount of heat produced and heat that is released to the outside environment through physical models of conduction, convection and evaporation. Prolonged exposure to heat stress can negatively affect health-productive traits. The adaptive response of animals to heat stress involves physiological, behavioral and metabolic reactions in order to maintain thermoregulation. The main effect of heat stress is a decrease in milk production, so heat stress has great economic importance. The decrease in milk produc

Abstract In plant living tissue, water can flow across cells by different paths, through cell membranes (transcellular path) and plasmodesmata (symplastic path), or through the continuous cell walls matrix (apoplastic path). The relative contribution of these three paths in living tissue is currently unclear and could vary according to species, tissue developmental stage or physiological conditions. Experiments suggested that apoplastic water movement predominates during transpiration. The objective of this study was to investigate the hydraulic process of cellulose cell wall pathway. The effe

The necessity to improve broiler thermotolerance and live performance led to the following hypothesis: Appropriate comprehensive incubation treatments that include significant temperature management changes will promote angiogenesis and will improve acquisition of thermotolerance and carcass quality of heavy broilers through epigenetic adaptation. It was based on the following questions: 1. Can TM during embryogenesis of broilers induce a longer-lasting thermoregulatory memory (up to marketing age of 10 wk) that will improve acquisition of thermotolerance as well as increased breast meat yield

Our hypothesis was that postnatal stress exposure or sensory input alters brain activity, which induces acetylation and/or methylation on lysine residues of histone 3 and alters methylation levels in the promoter regions of stress-related genes, ultimately resulting in long-lasting changes in the stress-response set point. Therefore, the objectives of the proposal were: 1. To identify the levels of total histone 3 acetylation and different levels of methylation on lysine 9 and/or 14 during both heat and feed stress and challenge. 2. To evaluate the methylation and acetylation levels of histone

Background PHS (pulmonary hypertension syndrome, ascites syndrome) is a serious cause of loss in the broiler industry, and is a prime example of an undesirable side effect of successful genetic development that may be deleteriously manifested by factors in the environment of growing broilers. Basically, continuous and pinpointed selection for rapid growth in broilers has led to higher oxygen demand and consequently to more frequent manifestation of an inherent potential cardiopulmonary incapability to sufficiently oxygenate the arterial blood.
