  1. 1. Heat exposure and health outcomes in Costa Rican sugarcane harvesters

    University dissertation from Umeå : Umeå universitet

    Author : Jennifer Crowe; Umeå universitet.; [2014]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Agricultural worker; Central America; Chronic kidney disease; Climate change; Dehydration; Heat; Heat illness; Heat stress; Sugarcane; Urinalysis; Worker health; folkhälsa; Public health; Epidemiology; epidemiologi;

    Abstract : Background The remarkably efficient mechanisms of the human body to maintain its core temperature of 37°C can be inadequate when harsh climatic conditions and excessive muscle movement lead to heat stress, dehydration and potential heat illness, ranging from minor symptoms such as fatigue to a potentially fatal heat stroke. Agricultural workers in the tropics are at high risk, which is expected to increase with climate change. READ MORE

  3. 3. Coping with Stress Regulation of the Caulobacter crescentus cell cycle in response to environmental cues

    University dissertation from Stockholm : Department of Molecular Biosciences, The Wenner-Gren Institute, Stockholm University

    Author : Kristina Heinrich; Stockholms universitet.; [2018]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Caulobacter crescentus; bacteria; cell cycle; stress; filamentation; cell morphology; DNA replication; cell division; molekylär biovetenskap; Molecular Bioscience;

    Abstract : All organisms have to respond to environmental changes to maintain cellular and genome integrity. In particular, unicellular organisms like bacteria must be able to analyze their surroundings and rapidly adjust their growth mode and cell cycle program in response to environmental changes, such as changes in nutrient availability, temperature, osmolarity, or pH.
