- Formant structure of the voice during the intensive acute hypoxia. Obrenovic, Jovi�a; Ne�ic, Milkica; Ne�ic, Vladimir; Cekic, Snezana // Vojnosanitetski Pregled: Military Medical & Pharmaceutical Journ;Mar/Apr2003, Vol. 60 Issue 2, p155
The influence of intensive acute hypoxia on the frequency-amplitude formant vocal O characteristics was investigated in this study. Examinees were exposed to the simulated altitudes of 5 500 m and 6 700 m in climabaro chamber and resolved Lotig 's test in the conditions of normoxia, i.e....
- Hooray for Hypoxia? Bellingan, Geoff // PLoS Medicine;Jun2005, Vol. 2 Issue 6, p0480
Comments on a study on the benefits of hypoxia for patients with lung injury. Risks of hypoxia and hyperoxia; Association of hypoxia with elevated adenosine concentrations; Evidence that prolonged hypoxia can affect many processes.
- The impact of hypoxia on our body: from integrative physiology to human disease. Gassmann, Max // Cellular & Molecular Life Sciences;Nov2009, Vol. 66 Issue 22, p3537
The article discusses the role of hypoxia in the human body. It states that hypoxia has a significant role in almost all acute and chronic diseases. It is also noted that reduced oxygenation occurs under normal physiological circumstances such as embryonic development, physical activity and...
- Carrot and stick: HIF-Î± engages c-Myc in hypoxic adaptation. Huang, L. E. // Cell Death & Differentiation;Apr2008, Vol. 15 Issue 4, p672
The past decade of research on hypoxic responses has provided a considerable understanding of how cells respond to hypoxic stress at the molecular level, thanks to the identification and molecular cloning of the hypoxia-inducible transcription factor, HIF-1Î±. Numerous target genes have since...
- Effects of anoxia and sulfide on concentrations of total and methyl mercury in sediment and water in two Hg-polluted lakes. Regnell, Olof; Hammar, Tommy; Helgée, Anders; Troedsson, Bo // Canadian Journal of Fisheries & Aquatic Sciences;Mar2001, Vol. 58 Issue 3, p506
Between May and December 1996, monthly samples of surface sediment (0â€“1 cm), settling matter, and water were taken at a shallow site and a deep site in each of two consecutive Hg-polluted riverine lakes. In the upper lake, the sediment was polluted also with cellulose fiber. Both...
- Are You a Hypoxia Expert? Brooks, Kevin E. // Approach: The Naval Safety Center's Aviation Magazine;May/Jun2005, Vol. 50 Issue 3, p8
Presents a question and answer advisories in handling hypoxia during air flight. Causes of hypoxia during high altitude flights; Types of hypoxia; Definition of the oxygen paradox.
- Oxygen Para-what? Ostrander, Greg // Approach: The Naval Safety Center's Aviation Magazine;May/Jun2005, Vol. 50 Issue 3, p13
Focuses on the oxygen paradox which occurs to pilots upon reoxygenation after periods of either prolonged or severe hypoxia. Causes of such phenomenon; Misconceptions of handling the oxygen paradox; Results of controlled runs on the reduced oxygen-breathing device.
- The hypoxia-inducible factors: key transcriptional regulators of hypoxic responses. Bracken, C. P.; Whitelaw, M. L.; Peet, D. J. // Cellular & Molecular Life Sciences;Jul2003, Vol. 60 Issue 7, p1376
Oxygen depravation in mammals leads to the transcriptional induction of a host of target genes to metabolically adapt to this deficiency, including erythropoietin and vascular endothelial growth factor. This response is primarily mediated by the hypoxia-inducible factors (HIFs) which are members...
- Matched adaptations of electrophysiological, physiological, and histological properties of skeletal muscles in response to chronic hypoxia. Faucher, Marion; Guillot, Chantal; Marqueste, Tanguy; Kipson, Nathalie; Mayet-Sornay, Marie-Hélène; Desplanches, Dominique; Jammes, Yves; Badier, Monique // Pflugers Archiv European Journal of Physiology;Apr2005, Vol. 450 Issue 1, p45
This study tried to differentiate the consequences of chronic hypoxia on the electrophysiological and physiological properties and the histological characteristics of slow and fast muscles in rats. Animals inhaled a 10% O2 concentration for a 1-month period. Then, slow [soleus (SOL)] and fast...
