Abstract:

The present investigation was designed to elucidate the potential influence of age on speech breathing. Toward this end, 30 men representing three widely different age groups (25, 50, and 75 years) were studied. These individuals were carefully selected to meet stringent criteria, the most important of which related to health and physical characteristics. Speech breathing was studied via anteroposterior diameter changes of the rib cage and abdomen. Recordings were made during extemporaneous speaking and reading and during the performance of various chest wall maneuvers used in the measurement

Abstract:

A comparison of heart rate viability and respiratory sinus arrhythmia (RSA) characteristics was performed in 20 athletes and 12 age-matched sedentary controls (CTRL) (22 +/- 2.4 yrs). More specifically, this study examined the role of regular physical activity on the breathing frequency (BF)---RSA amplitude response curve comparing varsity swimmers (SW) to endurance runners (RU) to test the hypothesis that a locomotor-respiratory entrainment resulting from the water-immersion breathing pattern of swimmers would alter their respiratory related cardiac vagal integrative response.

Abstract:

Cigarette smoking is a common and lethal worldwide habit, with considerable mortality stemming from its deleterious effects on heart function. While current theories posit altered blood lipids and fibrinogen metabolism as likely mediators, none have explored the role of the sphingolipid ceramide in exacerbating heart function with smoke exposure. Ceramide production is a consequence of cigarette smoke in the lung, and considering ceramide's harmful effects on mitochondrial function, we sought to elucidate the role of ceramide in mediating smoke-induced altered heart mitochondrial respiration.

Abstract:

The cold season in the Arctic extends over eight to nine months during which ecosystem gas exchange and water balance of arctic plants have been largely unexplored. The overall objective of this thesis was to examine two critical gaps in our knowledge about tundra cold season processes – ecosystem respiration at very low temperatures and water uptake during the winter-spring transition. I determined the temperature response of ecosystem respiration of tundra monoliths down to temperatures as low as can be expected under snow-covered conditions (-15 °C). Temperature responses fit the Arrhenius

Abstract:

Fallopia japonica, or Japanese knotweed is a rhizomatous perennial herb native to East Asia; most notably Japan, China and Korea. Upon discovery of this species and subsequent import to Europe in the 1840's, it was considered an esteemed ornamental plant – winning the medal for the ‘most interesting new plant of the year' in 1847. F. japonica soon became known as a menace rather than a champion, when it began to spread throughout its new environment, spreading to gardens and nurseries and regenerating from discarded plant fragments.

This thesis is concerned with a very common disorder of iron homeostasis: iron deficiency. The specific focus is the manner in which iron deficiency influences physiological responses to hypoxia in humans. This work is predicated on observations made over many decades in vitro and in vivo, suggesting that variations in the bioavailability of iron have important consequences for certain biological processes known to depend on oxygen availability. Three separate but related studies together form the basis for this thesis. The first two, Study A and Study B, adopt a similar approach in recruiting

Loblolly pine (Pinus taeda L.) occupies 13 million hectares in the United States and represents a critical component of the global carbon (C) cycle. Forest management alters C dynamics, affecting the C sequestration capacity of a site. Identifying drivers that influence C cycling, quantifying C fluxes, and determining how management alters processes involved in C cycling will allow for an understanding of C sequestration capacity in managed forests. Objectives of the first study included (1) investigating environmental, soil C, root, and stand influences on soil CO2 efflux on the South Caro

<p>Estuarine organisms, such as juvenile penaeid shrimp, experience fluctuating oxygen pressures on a daily basis. In coastal waters of the southeastern United States, severe hypoxia (< 4–6 kPa) is common in the summer, also a time during which bacterial concentrations in seawater are high. In response to invading bacteria, crustaceans mount an immune defense resulting in aggregations of circulating hemocytes. These aggregates can be trapped in and obstruct hemolymph flow through the gills, inhibiting oxygen uptake. Hypoxia itself is also known to inhibit immune function. In this stud

Abstract:

Two Australian frogs were introduced to New Zealand over 100 years ago. Since their introduction they have become widespread and well established with Litoria ewingii being more prevalent in alpine and cooler areas of New Zealand, while Litoria raniformis is found in more temperate coastal areas. Very little physiological data exists for these frogs and aside from their distribution not much is known about them in New Zealand. Thus the effects of thermal acclimation and temperature change on respiration and locomotion were examined in these two exotic frogs. The more terrestrial and alpine dwe

Abstract:

The New Zealand freshwater crayfish P. zealandicus emerges from water and exposes it's respiratory surface to desiccation and collapse, it's haemolymph to acid-base disturbance and it's tissues to hypoxia. This study was to investigate the respiratory system during aerial respiration. P. zealandicus has 20 gills, a rudimentary gill and an epipodite (20 + r + ep). Two types of gill filament were identified; a respiratory filament with a cuticle 0.7µm thick, an afferent and efferent vessel and haemolymph lacunae adjacent to the cuticle, and an ion regulating filament with a cuticle 1.2µm thick

Abstract:

The desert-adapted frogs Cyclorana platycephala and Cyclorana maini survive long periods of inhospitably hot and dry conditions by retreating underground and aestivating. While aestivating they suspend food and water intake as well as physical activity, depress their metabolic rate by ~80 %, and form cocoons that protect them against desiccation. How these frogs function during this exceptional state is largely unknown. This work characterized a number of physiological parameters in three metabolic states spanning their natural metabolic range: during aestivation (depressed metabolism), at res

Blue gouramis are obligatory air breathing fish that possess a labyrinth-like structure that serves as the air breathing organ.

The underlying rationale is to reduce exposure to redox and nitrosative stimuli generated during several hours of exposure to 95% O2 that produces a tissue O2 tension throughout the slice which is in excess of 203 kPa (2.0 atmospheres absolute,ATA) oxygen. Whole cell recordings of cSC neurons maintained in 40% O2 exhibited spontaneous firing

In active shallow-water cephalopods, these traits result in an interesting combination of very high oxygen demand and limited ox
