The impact of hyperoxia on brain activity: A resting-state ...
This study applied electroencephalography (EEG) in healthy subjects and investigated how high a concentration of oxygen in inhaled air (i.e., normobaric hyperoxia) alters brain activity under resting-state and task-evoked conditions.

Effect of pathological changes of pH, pO2 and pCO2 on the ...
Since standard susceptibility tests reflect the physiological rather than the pathological conditions prevailing within an infected abdomen, as recently documented, the effect of reduced pH and pO2 and increased pCO2 on the activity of antibiotics in vitro was studied.

Physiological and Pathological Responses to Hypoxia
Studies on isolated mitochondria have shown that the main effects of decreased oxygen availability on mitochondrial respiration is an inhibition of the respiratory chain and an increase of the proton leak, while phosphorylation is less affected. 12,13 The inhibition of the respiratory chain occurs at pO 2 levels high above the K m of cytochrome c oxidase, indicating that a specific inhibiting mechanism still unknown is switched on well before oxygen concentration

Pathological and Therapeutic Significance of Cellular ...
Proteus mirabilis infection often leads to stone formation. We evaluated how bacterium-mucin adhesion, invasion, and intracellular crystal formation are related to antibiotic sensitivity and may cause frequent stone formation in enterocystoplasties. Five intestinal (Caco-2, HT29, HT29-18N2, HT29-FU, and HT29-MTX) and one ureter cell line (SV-HUC-1) were incubated in artificial urine with five ...

Research Advances in the Mechanisms of Hyperuricemia ...
Uric acid is the end product of purine metabolism in humans, and its excessive accumulation leads to hyperuricemia and urate crystal deposition in tissues including joints and kidneys. Hyperuricemia is considered an independent risk factor for cardiovascular and renal diseases. Although the symptoms of hyperuricemia-induced renal injury have long been known, the pathophysiological molecular ...

2011-8-6 Chinese herbs Desmodium styracifolium (Ds) and Pyrrosiae petiolosa (Pp) have been widely used to treat urolithiasis with few side effects in traditional Chinese medicine (TCM). In vitro crystallization study has confirmed their prophylaxis of Calcium oxalate (CaO x ) stones formation. However, little is known on their possible mechanisms in vivo. In the present study, we proposed to ...

Urobilinogen in Urine: Low High Levels + Normal Range ...
2021-4-7 Urobilinogen is a byproduct of bilirubin that is eventually eliminated through the stool and urine. Although urobilinogen is normally found in the urine, higher or lower levels may be a sign of a liver problem. Read on to find out what urobilinogen is, how it can be tested, and what its levels may reveal about your health.

The effect of these two forces recently was studied in the context of high physiological crystal concentrations, renal tubular and pelvic dimensions and urinary transit times in the kidney. Crystals are even at the maximal concentration of 24000/cm 3 assumed in idiopathic Ca stone formers[ 9 ] on average in a distance of about 350 µ.

Hypoxia and hypoxia-inducible factors in chronic kidney ...
2016-7-6 The kidney is physiologically considered hypoxic despite receiving up to 20 % of the cardiac output in humans. Oxygen pressure in the renal cortex of normal animals is reportedly between 10 and 60 mmHg, whereas the corticomedullary junction and medulla are exposed to marked hypoxia [3–7].One critical cause of kidney hypoxia, particularly in the medulla, is the arterial–venous oxygen shunt ...
