Previous knowledge suggested the involvement of specific pathways/proteins that could be identified as potential molecular indicators linked to enhanced drought tolerance in Eucalyptus globulus. Here, we looked for specific variations in key transcripts of two Eucalyptus globulus clones (AL-18 and AL-13) exposed to water deficit and rehydration with two main goals: (i) to check if and how transcripts potentially associated with stress response and protection are modulated in a controlled experiment; and (ii) to verify if the transcript response is robust in a field case study...

Heat exhaustion is part of a spectrum of heat-related illnesses that can affect all individuals, although children, older adults, and those with chronic disease are particularly vulnerable due to their impaired ability to dissipate heat. If left uninterrupted, there can be progression of symptoms to heatstroke, a life-threatening emergency. Signs and symptoms of heat exhaustion may develop suddenly or over time. Exposure to a hot environment for a prolonged period and performing exercise or work in the heat can overwhelm the body's ability to cool itself, causing heat exhaustion...

Cystic fibrosis (CF) is a chronic disease caused by mutations in the CF transmembrane conductance regulator ( CFTR ) gene, which encodes for a channel expressed at the apical surface of epithelial tissues. Defective chloride and bicarbonate secretion, arising from CFTR mutations, cause a multi-organ disease. In the airways, impaired ion transport results in a thick mucus, dehydration of the periciliar region and bacterial infections. Over the last years, basic research has sustained a great effort to identify therapies that are able to correct defective CFTR...

BACKGROUND: Heat stress and rhabdomyolysis are major risk factors for the occurrence of repeated acute kidney injury in workers exposed to heat and strenuous work. These episodes, in turn, may progress to chronic kidney disease. OBJECTIVE: The purpose of this study was to test the effect of allopurinol (AP) and sodium bicarbonate on the kidney injury induced by recurrent heat stress dehydration with concomitant repeated episodes of rhabdomyolysis. METHODS: The model consisted of heat stress exposure (1 h, 37°C) plus rhabdomyolysis (R) induced by repetitive IM injections of glycerol (7...

Chronic kidney disease (CKD) affects the kidneys, and in severe cases is considered as end-stage renal disease which can only be treated by dialysis and transplantation. Tierra Blanca city has a higher CKD rate compared to other Mexican cities, but its principal cause has not been found yet. Main factors related to CKD are carbonated beverage consumption, diabetes, obesity, hypertension, heat stress, dehydration, and intoxication by pesticides, heavy metals, and/or hydrocarbons. The aim of this work was to evaluate hydrocarbon pollution in Tierra Blanca domestic fresh-water related to CKD and to integrate this information with other main factors in order to suggest precautionary actions taking account of key actors...

INTRODUCTION: Cystic fibrosis (CF) is a genetic disease primarily affecting the lungs, which could lead to chronic respiratory failure and premature death. CF patients are usually followed in specialized centers, but may present outside of these centers when they seek care for acute pulmonary and/or non-pulmonary complications. The aim of this paper is to provide appropriate knowledge necessary for managing respiratory and non-respiratory emergencies in CF adults. METHODS: The review is based on international guidelines, extensive search of the available literature using Pubmed, and experience of the CF reference center at Cochin hospital (Paris, France)...

Purple urine bag syndrome (PUBs) is a rare and startling phenomenon of purple discolouration in the urine or urinary catheter and bag. It is reported in chronically debilitated elderly patients, mostly in women on long-term urinary catheters. Its prevalence is strikingly more common in nursing home residents. Several factors contribute to the formation of indigo (blue) and indirubin (red) pigments from a breakdown of dietary tryptophan, which stains the urine purple. These factors include constipation, dysmotility of the bowel, bowel bacterial overgrowth, dehydration, and urinary tract infection...

A fatal outbreak of sarcoptic mange caused by Sarcoptes scabiei in San Joaquin kit foxes ( Vulpes macrotis mutica) in Bakersfield, California, USA is causing the once-stable population to decline. Given the fatality of the disease in this already-endangered species experiencing continued population declines, city-wide interventions are underway. To optimize medical management of mange-infested kit foxes, we documented serum biochemistry and hematology values for 11 kit foxes with mange collected from January-May 2015 and compared them to historical data from 18 healthy Bakersfield kit foxes...

Historically used as an anesthetic, chloroform is a halogenated hydrocarbon that is associated with central nervous system depression, arrhythmias, and hepatotoxicity. It is no longer used clinically, but accidental and intentional poisonings still occur. We report a case of chronic chloroform abuse leading to severe hepatotoxicity in a 26-year-old male graduate student. The patient presented to the emergency department with a three-day history of abdominal pain, dehydration, and scleral icterus. He drank several beers the night before the onset of symptoms, but denied taking acetaminophen, ibuprofen, or other drugs...

REVIEW

Acute kidney injury (AKI) is a common and life-threatening complication in critically ill neonates. Gestational risk factors for AKI include premature birth, intrauterine growth restriction and low birthweight, which are associated with poor nephron development and are often the consequence of pre-gestational and gestational factors, such as poor nutritional status. Our understanding of how to best optimize renal development and prevent AKI is in its infancy; however, the identification of pre-gestational and gestational factors that increase the risk of adverse neonatal outcomes and the implementation of interventions, such as improving nutritional status early in pregnancy, have the potential to optimize fetal growth and reduce the risk of preterm birth, thereby improving kidney health...

Nitric oxide (NO) is a gaseous free radical that in diverse organisms performs many signaling and protective functions, such as vasoregulation, inhibition of apoptosis, antioxidation, and metabolic suppression. Increased availability of NO may be especially important during life-history periods when organisms contend with multiple stresses. We investigated dynamics of the NO metabolites, nitrite (NO2 - ) and nitrate (NO3 - ), in the blood plasma, heart, liver, and skeletal muscle of the wood frog (Rana sylvatica), an amphibian that endures chronic cold, freezing, hypoxia, dehydration, and extended aphagia during hibernation...

Chronic wounds are a significant health care problem with serious implications for quality of life because they do not properly heal and often require therapeutic intervention. Amniotic membrane allografts have been successfully used as a biologic therapy to promote soft tissue healing; however, the umbilical cord, another placental-derived tissue, has also recently garnered interest because of its unique composition but similar placental tissue origin. The aim of this study was to characterize PURION® PLUS Processed dehydrated human umbilical cord (dHUC) and evaluate the biological properties of this tissue that contribute to healing...

The multi-organ disease cystic fibrosis (CF) is caused by mutations in the cystic fibrosis transmembrane regulator gene ( CFTR ) that lead to diminished transepithelial anion transport. CF lungs are characterised by airway surface liquid (ASL) dehydration, chronic infection/inflammation and neutrophilia. Dysfunctional CFTR may upregulate the epithelial Na+ channel (ENaC), further exacerbating dehydration. We previously demonstrated that short palate lung and nasal epithelial clone 1 (SPLUNC1) negatively regulates ENaC in normal airway epithelia...

Background: "Dry mouth" syndrome (chronic hyposalivation) can be caused by a number of pathophysiological conditions such as acute and chronic stress exposure, abnormal body weight (both too high and too low ones), eating disorders (such as anorexia nervosa ), metabolic syndrome(s), Sjögren's and Sicca syndromes, drugs and head/neck radiotherapy application. In turn, the chronic hyposalivation as a suboptimal health condition significantly reduces quality of life, may indicate a systemic dehydration, provokes and contributes to a number of pathologies such as a strongly compromised protection of the oral cavity, chronic infections and inflammatory processes, periodontitis, voice and digestive disorders...

BACKGROUND: Cystic Fibrosis is an autosomal recessive disorder with a mutation in the cystic fibrosis transmembrane regulator gene, leading to dysregulation of epithelial fluid transport, dehydration of airway surfaces and impaired mucociliary function in the sinuses, lungs, pancreas and other organs. This leads to thickened secretion which blocks the sinus ostia and promotes chronic bacterial overgrowth and destruction of the mucosa. Chronic rhinosinusitis in cystic fibrosis patients leads to a decreased quality of life involving increased hospitalizations, infections, pneumonia, and acute exacerbations, warranting multiple sinus surgeries...

Celiac disease (CD)-also known as gluten-sensitive enteropathy-is a chronic, genetically predisposing and autoimmune entity with a wide range of clinical manifestations triggered by gluten ingestion, which affects 1% of the general population. Currently, up to 60% of the diagnosis of CD is in adults due to the atypical course of the disease. The severe acute onset of CD-also called celiac crisis-is very uncommon and is still not well documented in adults. We report the case of a 58-year-old man who presented a 45-day history of subtle-onset diarrhea followed by malabsorption syndrome with progressive weight loss, anasarca, and electrolyte disturbances...
