Effects on blood pressure of reduced dietary sodium and the Dietary Approaches to Stop Hypertension (DASH) diet

open access: yes, 2001
Background The effect of dietary composition on blood pressure is a subject of public health importance. We studied the effect of different levels of dietary sodium, in conjunction with the Dietary Approaches to Stop Hypertension (DASH) diet, which is ...

The Role of Voltage-Gated Sodium Channels in Pain Signaling.

open access: yesPhysiological Reviews, 2019
Acute pain signaling has a key protective role and is highly evolutionarily conserved. Chronic pain, however, is maladaptive, occurring as a consequence of injury and disease, and is associated with sensitization of the somatosensory nervous system ...

Evaluation of Three Hydration Strategies in Detection Dogs Working in a Hot Environment

open access: yesFrontiers in Veterinary Science, 2017
Physical activity in hot environments can increase the risk of heat stress or heat stroke in dogs. Heat tolerance is influenced by acclimatization to the environment, physical fitness, and hydration state.

Sodium modeling

open access: yesKidney International, 2000
The most serious side effects induced by hemodialysis therapy are caused by changes in sodium concentration and subsequent water shift between the intracellular and extracellular fluid compartment. Because of inadequate precision of proportioning, a certain sodium concentration and considerable error in the measurement of sodium concentration in ...

Using Electrolyte Free Water Balance to Rationalize and Treat Dysnatremias

open access: yesFrontiers in Medicine, 2018
Dysnatremias or abnormalities in plasma [Na+] are often termed disorders of water balance, an unclear physiologic concept often confused with changes in total fluid balance. However, most clinicians clearly recognize that hypertonic or hypotonic gains or

Renal sodium handling and sodium sensitivity

open access: yesKidney Research and Clinical Practice, 2017
The pathophysiology of hypertension, which affects over 1 billion individuals worldwide, involves the integration of the actions of multiple organ systems, including the kidney. The kidney, which governs sodium excretion via several mechanisms including pressure natriuresis and the actions of renal sodium transporters, is central to long term blood ...

Sodium Atoms in the Lunar Exotail: Observed Velocity and Spatial Distributions [PDF]

open access: yes, 2011
The lunar sodium tail extends long distances due to radiation pressure on sodium atoms in the lunar exosphere. Our earlier observations measured the average radial velocity of sodium atoms moving down the lunar tail beyond Earth (i.e., near the anti ...
