Abstract:

Due to the high metabolic rate of brain tissue and nominal substrate storage, brain perfusion must be precisely regulated to ensure continuous delivery of oxygen and substrates. Cerebral blood flow (CBF) is principally regulated by tissue metabolism, perfusion pressure, autonomic nervous activity, and the partial pressures of arterial oxygen (PaO₂)and carbon dioxide (PaCO₂) – an integrative process thus involving the marked influence of pulmonary gas exchange and cardiovascular function, in addition to intracranial mediators of cerebrovascular resistance. This thesis explicates the roles of

Abstract:

"In the past decades, safe and effective artificial oxygen carriers (AOC), also named as “blood substitutes”, have been proposed and extensively studied in chemistry and medical science. The constant necessity of donor blood is crucial for diverse medical situations, such as accidents and casualties which result in acute blood loss and the need to restore oxygen transport to the tissues. The inherent complications associated to the traditional blood transfusion make urgent the formulation of new suitable alternatives.(1–4)(...)"<br>info:eu-repo/semantics/publishedVersion

Abstract:

Arterial desaturation in fit athletes, during exercise at an intensity greater than or equal to 90% of VO₂ max has been reported by a number of authors yet the etiology of these changes remain obscure. Inadequate pulmonary ventilation due to a blunted respiratory drive, or lung mechanics has been implicated as a factor in the etiology of this phenomenon. It was the purpose of this experiment to investigate the relationship between arterial desaturation and ventilatory response to hypoxia (HVR).

Abstract:

Eight healthy female volunteers (mean age 24.4 ± 3.4) served as subjects in an experiment measuring acid-base and lactate changes while breath-holding during intense, intermittent exercise. The subjects were endurance trained (VO₂[sub max] = 56.8 ± 3.9 ml'kg-min⁻¹) with normal resting pulmonary function. Utilizing a counterbalance design, each subject repeated 5 intervals of a 15 second treadmill run at 125 % VO₂[sub max], once while breath-holding (BH), and once while breathing freely (NBH). Blood samples at rest, at the end of each work and rest interval, and throughout recovery were tak

Abstract:

This purpose of this study was to evaluate the contribution of post-dive peripheral tissue warming to the production of venous gas emboli (VGE) in divers. Inert gas elimination from the tissues is limited by both perfusion and diffusion. If changes in diffusion are matched by corresponding perfusion (vasoactive) changes, decompression should be asymptomatic (within allowable exposure limits). Under conditions when the diffusion of inert gas from the tissues is not matched by blood perfusion, VGE will ensue. Increasing tissue temperature will decrease inert gas solubility and thus diffusion in

Abstract:

The effects of water pH, hardness and temperature on anesthesia induction and recovery in silver catfish exposed to different concentrations of eugenol (20, 30 and 40 mg/L) were investigated. Moreover, the effects of anesthesia and temperature on blood gases tensions (PvO2 and PvCO2) and pH were also analyzed in juveniles I (3.5 ± 0.7 g; 7.7 ± 0.8 cm) and juveniles II (152.2 ± 3.4 g; 26.6 ± 3.3 cm) of silver catfish. Water quality and fish size affect efficacy of eugenol in silver catfish, mainly in the lower concentrations tested. Sedation of this species can be induced even with 20 mg/L, but

When Brian Friel’s play The Freedom of the City premiered in 1973, just a year after the events of Bloody Sunday, it was met with harsh criticism and called a work of propaganda.

These three protestors, disoriented by violence as well as the aftereffects of life-long poverty, on the surface are not emblems of morality.
