Absorption of water and sodium and activity of adenosine triphosphatases in the rectal mucosa in tropical sprue

open access: yes, 1989
In 10 southern Indian patients with tropical sprue, in vivo dialysis showed a defect of absorption of water and sodium from the rectum, when compared with 11 healthy volunteers. Sodium-potassium-ATPase activity, measured in homogenates of rectal biopsies,

Expression of Mineral and Urea Transport‐Related Genes in the Salivary Glands and Ruminal Epithelium of Young Goats Fed Nitrogen‐ and/or Calcium‐Reduced Diets

open access: yesJournal of Animal Physiology and Animal Nutrition, EarlyView.
ABSTRACT An adequate supply of protein and minerals, particularly nitrogen (N) and calcium (Ca), is essential for ruminant growth and metabolic function. The rumen and salivary glands are crucial for nutrient and electrolyte homoeostasis via specialised transport proteins.

Sodium/Potassium-transporting ATPase Subunit Alpha-3 Antibody is not Present in Patients with Idiopathic Intracranial Hypertension [PDF]

open access: yes
Aim: Increased cerebrospinal fluid (CSF) oligoclonal band prevalence, elevated cytokine levels, glial antibodies, and positive response to steroids have been described in idiopathic intracranial hypertension (IIH), suggesting autoimmune etiology in this ...

Ion Channel Dysfunction and Therapeutic Targeting in Salivary Gland Disorders

open access: yesOral Diseases, EarlyView.
ABSTRACT Objective Salivary gland hypofunction and xerostomia represent major clinical complications of radiation therapy, autoimmune disorders such as Sjögren's disease, and inherited epithelial ion transport defects. This review integrates current knowledge on ion channel dysfunction as a central mechanistic driver of salivary gland pathology and ...

Mitochondrial Respiratory Metabolism in Salt‐Stressed Barley (Hordeum vulgare): TCA Cycle Activation With Limited GABA Shunt Engagement

open access: yesPlant, Cell &Environment, EarlyView.
ABSTRACT Plants maintain energy balance under salinity stress through increased respiration and energy use, processes also associated with reactive oxygen species generation. Although respiration imposes a high energy cost, mitochondrial respiration and the tricarboxylic acid (TCA) cycle activity are vital for ATP production and for providing electron ...

Metabolic stimulation improves bioenergetics and haematologic indices of circulating erythrocytes from sickle cell mice

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Metabolic stimulation improves bioenergetics, redox state, hydration and hematologic indices of circulating erythrocytes from sickle cell mice. Retained mitochondria in circulating RBCs from sickle mice are a source of RBC ATP as mitochondria function (ETC, electron transport chain) inhibitors [rotenone, a mitochondrial complex I

Placental mitochondrial metabolic adaptation maintains cellular energy balance in pregnancy complicated by gestational hypoxia

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Placental mitochondrial adaptation to gestational hypoxia. Hypoxic pregnancy in sheep increases placental insulin like growth factor 2 (IGF2) signalling (1), which is associated with a shift in capacity away from β‐oxidation (2) and complex I‐mediated respiration (3), while maintaining total oxidative phosphorylation capacity (4).

Cellular mechanisms of radiation‐induced myocyte dysfunction: effects on calcium handling, ion channel regulation and mitochondrial energetics

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Dose‐dependent effects of radiation on cardiac electrophysiology and arrhythmia susceptibility. At low radiation doses (left), increased reactive oxygen species (ROS) initiate an ROS–Ca2+ positive feedback loop involving calcium/calmodulin‐dependent protein kinase II (CaMKII) activation, enhanced L‐type Ca2+ current (ICaL ...

Human‐derived cardiac‐neural microtissues reveal catecholaminergic polymorphic ventricular tachycardia is also a disease of the sympathetic neuron

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic diagram illustrating the proposed pathway in which regulatory defects might occur in sympathetic neurons derived from hiPSC in catecholaminergic polymorphic ventricular tachycardia (CPVT). Specifically, enhanced calcium transients appeared to derive from three sources: enhanced membrane excitability (due to loss of ...

Extracellular ionic concentration modulates arrhythmias in a simulated population of human ventricular myocytes with long QT syndrome type 3

open access: yesThe Journal of Physiology, EarlyView.
Abstract figure legend Schematic illustrating the in silico study pipeline. A total of 50,000 virtual myocytes were generated, which were then filtered to 7093 myocytes that fit experimentally constrained biomarkers for physiological electrical and calcium behaviour under wild‐type conditions.
