Factors controlling spatio-temporal variation in carbon dioxide efflux from surface litter, roots, and soil organic matter at four rain forest sites in the eastern Amazon [PDF]

, 2007
[1] This study explored biotic and abiotic causes for spatio-temporal variation in soil respiration from surface litter, roots, and soil organic matter over one year at four rain forest sites with different vegetation structures and soil types in the ...

Respiration rate and volume measurements using wearable strain sensors. [PDF]

, 2019
Current methods for continuous respiration monitoring such as respiratory inductive or optoelectronic plethysmography are limited to clinical or research settings; most wearable systems reported only measures respiration rate.

Does surgically resected small‐cell lung cancer without lymph node involvement benefit from prophylactic cranial irradiation?

Thoracic Cancer, 2020
Background It has previously been demonstrated that surgically resected small‐cell lung cancer (SCLC) patients could benefit from prophylactic cranial irradiation (PCI). However, PCI in patients without lymph node involvement remains controversial.

Ecosystem respiration: Drivers of daily variability and background respiration in lakes around the globe [PDF]

, 2013
We assembled data from a global network of automated lake observatories to test hypotheses regarding the drivers of ecosystem metabolism. We estimated daily rates of respiration and gross primary production (GPP) for up to a full year in each lake, via ...

KATP Channel Openers Have Opposite Effects on Mitochondrial Respiration Under Different Energetic Conditions [PDF]

, 2008
Mitochondrial (m) KATP channel opening has been implicated in triggering cardiac preconditioning. Its consequence on mitochondrial respiration, however, remains unclear. We investigated the effects of two different KATP channel openers and antagonists on

Controls on ecosystem respiration of carbon dioxide across a boreal wetland gradient in Interior Alaska [PDF]

, 2012
Thesis (M.S.) University of Alaska Fairbanks, 2012Permafrost and organic soil layers are common to most wetlands in interior Alaska, where wetlands have functioned as important long-term soil carbon sinks.

Upregulation of MUC5AC by VEGF in human primary bronchial epithelial cells: implications for asthma

Respiratory Research, 2019
Background Airway mucus hypersecretion is an important pathophysiological feature in asthma. Mucins are glycoproteins that are mainly responsible for the viscoelastic property of mucus, and MUC5AC is a major mucin glycoprotein that is overproduced in ...

The growth and respiration of the Avena coleoptile [PDF]

, 1936
In a previous paper (1) a relation was shown to exist between the respiration of the plant cell and its elongation under the influence of the plant growth hormone.

Effect of Oxidative Stress and Fatty Acids Disbalance on the Development of Apoptosis in the Placenta with Cytomegalovirus Infection in the First Trimester

Acta Biomedica Scientifica, 2019
Background. Reactivation of cytomegalovirus infection (CMV) during pregnancy is associated with manifestation of oxidative stress, both in the maternal peripheral blood and in the placental tissues. One of the effects of oxidative stress is a disturbance
