Basal metabolism and respiration in men living at 5,800 m (19,000 ft)

Journal of Applied Physiology, 1964
Respiratory determinations were carried out on eight members of the Himalayan Scientific and Mountaineering Expedition 1960—1961 and three Sherpas during a prolonged stay at 5,800 m (19,000 ft). Ventilation and oxygen uptake were similar in both groups, although the Sherpas were smaller men.

SituResp®: A time- and cost-effective method to assess basal soil respiration in the field

Applied Soil Ecology, 2017
Abstract The soil microbial activity is a key parameter in numerous studies aiming to assess soil quality in agricultural plots. Basal Soil Respiration (BSR) has been extensively used as an indicator of this soil microbial activity. However, available methods to measure BSR remain time- and labor- consuming and must be performed in the laboratory ...

Basal and maintenance respiration of mycorrhizal and nonmycorrhizal root systems of conifers

Canadian Journal of Forest Research, 1987
We measured CO2 efflux from root systems of mycorrhizal and nonmycorrhizal conifer seedlings planted in silica sand and maintained in darkness for 11 to 15 days. We first compared methods of isolating the root system for root respiration measurement using Douglas-fir seedlings (Pseudotsugamenziesii (Mirb.) Franco).

Basal rates of soil respiration are correlated with photosynthesis in a mixed temperate forest

Global Change Biology, 2007
AbstractMany field studies have demonstrated that soil temperature explains most of the temporal variation in soil respiration (SR). However, there is increasing evidence to suggest that SR is also influenced by current, or recent, photosynthate. Accordingly, seasonal changes in SR nominally attributed to temperature may, in part, be due to seasonality

Stimulating basal mitochondrial respiration decreases doxorubicin apoptotic signaling in H9c2 cardiomyoblasts

Toxicology, 2015
Doxorubicin (DOX) is currently used in cancer chemotherapy, however, its use often results in adverse effects highlighted by the development of cardiomyopathy and ultimately heart failure. Interestingly, DOX cardiotoxicity is decreased by resveratrol or by physical activity, suggesting that increased mitochondrial activity may be protective. Conversely,

Bioremediation with Compost of a Diesel Contaminated Soil: Monitoring by Dehydrogenase Activity and Basal Respiration

Compost Science & Utilization, 2009
The effect of compost on hydrocarbon degradation was determined during a 120-d incubation period. An evaluation of soil basal respiration and dehydrogenase activity as a monitoring instrument for the bioremediation process of soil contaminated with commercial diesel-oil was carried out.

Are the soil microbial biomass and basal respiration governed by the climatic regime?

Soil Biology and Biochemistry, 1990
Abstract Soils in C equilibrium from various climatic regions were sampled to assess the influence of macroclimate on soil microbial biomass (C mic ) and basal respiration (CO 2 -evolution). C mic was measured using the substrate-induced respiration technique.

Effects of water amendment on basal and substrate-induced respiration rates of mineral soils

Biology and Fertility of Soils, 1989
We studied the effects of amending soils with different volumes of water or glucose solution on respiration rates measured as CO2 evolution. Basal respiration was not significantly affected by the volume of water amendment, but substrate-induced respiration in static soil solutions was significantly reduced by increasing water contents.

The effects of heavy metal pollution on enzyme activities and basal soil respiration of roadside soils

Environmental Monitoring and Assessment, 2007
In this study, soil samples (0-5 cm depth) were taken from ten different roadside fields of intensive traffic regions of Van-Turkey in order to determine the effects of heavy metal pollution on enzymes and microbial activities of soils. Basal soil respiration (BSR), arylsulphatase (ASA), alkaline phosphatase (APA) and urease (UA) enzyme activities, and

Respiration test as a possible substitute for the usual basal rate determinations*

The Journal of the American Pharmaceutical Association (1912), 1927
Abstract The author presents that the breath-holding power or capacity, in seconds with lungs deflated, under basal rate conditions, yields results which harmonize closely with the results obtained by means of the metabolors.
