Objective: Acute mesenteric ischemia (IMA) is a vascular emergency with broad variability of clinical presentations and non-specific laboratory findings. Therefore, there is a significant need for reliable serological markers of ischemia. Various laboratory studies may be performed for suspected AMI, but in general, such studies will not establish the diagnosis.Me...

OBJECTIVE To validate the i-STAT, a portable hand-held analyzer that allows point-of-care measurement of blood gases, acid-base, lactate, and other blood variables in food animal practice for analysis of blood samples of newborn calves. DESIGN Prospective observational study. SETTING University teaching hospital. MEASUREMENTS AND MAIN RESULTS A total of 271 venous blood samples were analy...

Our objective was to understand the functional link between the composition of faecal microbiota and the clinical characteristics of adults with short bowel syndrome (SBS). Sixteen patients suffering from type II SBS were included in the study. They displayed a total oral intake of 2661±1005 Kcal/day with superior sugar absorption (83±12%) than protein (42±13%) or fat (39±26%). These patients d...

Midland painted turtles from Michigan were submerged at 3 degrees C in normoxic and anoxic water. In predive, and in turtles submerged for up to 150 days, plasma PO2, PCO2, pH, [Cl-], [Na+], [K+], total Mg, total Ca, lactate, glucose, and osmolality were measured; hematocrit and mass were determined, and plasma [HCO3-] was calculated. Anoxic turtles developed a severe metabolic acidosis, accumu...

OBJECTIVES In 1981, Peter A. Stewart published a paper describing his concept for employing Strong Ion Difference. In this study we compared the HCO3 levels and Anion Gap (AG) calculated using the classic method and the Stewart method. METHODS Four hundred nine (409) arterial blood gases of 90 patients were collected retrospectively. Some were obtained from the same patients in different time...

in order to comprise the effects of sodium bicarbonate supplementation on anaerobic performance and some plasma metabolites, 16 young male athletes (age 20.58?3.25, height 175.33?2.48 cm and bmi 21.57? 2.68 kg/m2) participated in two 400 m running sessions one hour following sodium bicarbonate or placebo (calcium bicarbonate) supplementation with the counterbalanced order. there were three bloo...

INTRODUCTION Critically ill patients might present complex acid-base disorders, even when the pH, PCO2, [HCO3-], and base excess ([BE]) levels are normal. Our hypothesis was that the acidifying effect of severe hyperlactatemia is frequently masked by alkalinizing processes that normalize the [BE]. The goal of the present study was therefore to quantify these disorders using both Stewart and con...

Map turtles from Wisconsin were submerged at 3 degrees C in normoxic and anoxic water to simulate extremes of potential respiratory microenvironments while hibernating under ice. In predive turtles, and in turtles submerged for up to 150 days, plasma PO2, PCO2) pH, [Cl-], [Na+], [K+], total Mg, total Ca, lactate, glucose, and osmolality were measured; hematocrit and body mass were determined, a...

We have measured the metabolic activity in the vascularly isolated, salineperfused swimbladder of the eel (Anguilla anguilla) in order to investigate the pathways for CO2 formation in the gas gland tissue. Concentrations of O2, CO2, glucose and lactate were measured in the arterial inflow and venous outflow of the swimbladder, and metabolic rates were calculated by the direct Fick principle. 1....
