Single photon production by rephased amplified spontaneous emission [PDF]

open access: yes, 2013
The production of single photons using rephased amplified spontaneous emission is examined. This process produces single photons on demand with high efficiency by detecting the spontaneous emission from an atomic ensemble, then applying a population ...

Electrolyte handling in the isolated perfused rat kidney: demonstration of vasopressin V2-receptor-dependent calcium reabsorption

open access: yesUpsala Journal of Medical Sciences, 2020
Background The most profound effect of vasopressin on the kidney is to increase water reabsorption through V2-receptor (V2R) stimulation, but there are also data suggesting effects on calcium transport.

Stokes flow through a slit with periodic reabsorption: An application to renal tubule

open access: yesAlexandria Engineering Journal, 2016
This paper is concerned with the Stokes flow of an incompressible viscous fluid through a slit with periodic reabsorption at the walls. The momentum equation for the two dimensional flow is exactly solved in terms of stream function for two different ...

The role of hypoxia-induced modulation of alveolar epithelial Na- transport in hypoxemia at high altitude

open access: yesPulmonary Circulation, 2020
Reabsorption of excess alveolar fluid is driven by vectorial Na + -transport across alveolar epithelium, which protects from alveolar flooding and facilitates gas exchange.

Hypernatremia inhibits NaHCO3 reabsorption and associated NaCl reabsorption in dogs

open access: yesKidney International, 1986
To examine the effect of selective rise of plasma NaCl concentration (hypernatremia) on NaHCO3 reabsorption and associated NaCl reabsorption remaining during continuous ethacrynic acid infusion, hypertonic NaCl solution was infused in three groups of anesthetized volume-expanded dogs.

Urinary Reabsorption in the Rat Kidney by Anticholinergics [PDF]

open access: yesScientific Reports, 2021
Abstract Anticholinergics, therapeutic agents for overactive bladder, are clinically suggested to reduce urine output. We investigated whether this effect is due to bladder or kidney urine reabsorption. Various solutions were injected into the bladder of urethane-anesthetized SD rats.

ACTIVE CALCIUM REABSORPTION FOLLOWING KIDNEY TRANSPLANTATION

open access: yesВестник трансплантологии и искусственных органов, 2010
Active calcium and sodium reabsorption (ACR, SR) examination was performed in 125 renal recipients (RR) [78 with good renal function (GRF), 26 with chronic rejection(CR), 21 with cyclosporine nephrotoxity(CN)], 18 with bronchial asthma (36 estimation ...

Floral nectar reabsorption and a sugar concentration gradient in two long-spurred Habenaria species (Orchidaceae)

open access: yesBMC Plant Biology, 2023
Background Floral nectar is the most common reward flowers offered to pollinators. The quality and quantity of nectar produced by a plant species provide a key to understanding its interactions with pollinators and predicting rates of reproductive ...

Reducing Oxygen Demand to Alleviate Acute Kidney Injury

open access: yesFrontiers in Bioscience-Landmark, 2023
Maintaining a balance between the supply and demand of oxygen is vital for proper organ function. Most types of acute kidney injury (AKI) are characterized by hypoxia, a state where the supply of oxygen cannot match the demand for normal cellular ...
