The hawksbill turtle, Eretmochelys imbricata, is a marine chelonian with a circum-global distribution, but the species is critically endangered and has nearly vanished from the eastern Pacific. Although reference blood parameter intervals have been published for many chelonian species and populations, including nesting Atlantic hawksbills, no such baseline biochemical and blood gas values have ...

Obtaining and interpreting blood gases and electrolytes is fundamental to the management of many critically ill veterinary patients. Metabolic and electrolyte alterations are common, and can lead to profound clinical signs affecting many organs (including the heart, skeletal muscle, intestines and the lungs); when severe, death can ensue. This is the second of two articles describing the interp...

the mixing behavior of the gas-liquid phase in three loop bioreactors was investigated. a gas-induced external airlift loop bioreactor (ealb), a forced-liquid vertical tubular loop bioreactor (vtlb) and a forced-liquid horizontal tubular loop bioreactor (htlb) were used for mixing studies as well as biomass production from natural gas. the effect of design parameters, riser to downcomer cross s...

an experiment was conducted with two hundred and twenty day-old male broiler chicks (ross 308) in five groups to investigate the effects of different levels of 0, 0.2, 0.4 and 0.6% thyme extract in drinking water (including 27.4 mg sodium nitrate per liter) on broiler performance and antioxidantstatus and blood gas indices. no significant differences were observed between the treatments for bod...

response of tea plants to b deficiency was studied in hydroponic medium under environmentally controlled conditions. plants height, number of leaves and dry matter production of shoot and root were significantly decreased by b deficiency. concentration of chlorophyll, carotenoids, anthocyanins and flavonoids was not affected by b deficiency in the young leaf, while a significant reduction of ch...

OBJECTIVES To examine the impact of pulse oximetry on the use of arterial blood gas and other laboratory determinations and to examine predictors of the use of arterial blood gas measurements. DESIGN Before (preoximetry)/after (postoximetry) study. SETTING Thirty-bed multidisciplinary critical care unit. PATIENTS Consecutive admissions of 300 patients (150 before and 150 after oximetry). ...

ONE OF THE MOST RAPID and significant transformations in clinical practice that evolved from physiological research is the development of the modern, integrated blood gas analyzer (1, 2, 4). We take for granted the ability to measure PO2, PCO2, and pH in blood samples quickly and reliably. The significance of this technology has had wide-ranging effects in physiological research and clinical me...

background : the present study was undertaken to ascertain whether (or not) long term occupational exposure to low (sub-tlv levels) atmospheric concentrations of chlorine gas was associated with any significant decrements in the parameters of pulmonary function and/or  increased prevalence of respiratory symptoms. methods : in this retrospective cohort study that was performed in 2012, 54 worke...
