[1] In this paper, we analyzed 3 years of carbon flux data from continuous eddy covariance measurements to investigate how soil moisture, rain pulses, and growth alter the response of ecosystem respiration to temperature. The data were acquired over an annual grassland and from the grass understory of an oak/grass savanna ecosystem in California. We observed that ecosystem respiration was an ex...

The water availability in soil strongly influences crop growth by sustaining photosynthesis, respiration, and the maintenance of plant temperature. will decrease due to evapotranspiration (ETc) which is influenced reference (ETo) coefficient (Kc). During shortage, Kc evaporation (Ke) basal (Kcb) can be calculated using Blue Red Vegetation Index (BRVI). purpose this study was apply evaluate a ne...

Adenine nucleotide translocase 2 (ANT2) transports glycolytic ATP across the inner mitochondrial membrane. Patients with ANT2 deletion were recently reported. We aimed at characterizing mitochondrial functions in ANT2-defective fibroblasts. In spite of ANT2 expression in fibroblasts, we observed no difference between ANT2-defective and control fibroblasts for mitochondrial respiration, respirat...

Abstract Background Soil samples were taken after 27 years from a long-term field experiment to study the effects of composted pure cattle farmyard manure (FYM) and two FYM treatments with biodynamic preparations on soil chemical microbiological properties. Methods organic carbon (SOC), total nitrogen, basal respiration, fungal ergosterol, microbial biomass C (MBC) nitrogen (MBN) analyzed in 6-...

Abstract Macrophages are instrumental in maintaining immune homeostasis, and their dysfunction or depletion is tied to many human diseases, including autoimmunity, obesity, cancer. Activated macrophages modify cellular metabolic pathways, such as glycolysis oxidative phosphorylation, drive diverse functions. Many processes occur the mitochondria, metabolite production, reactive oxygen species (...

PURPOSE Cell death in neurodegeneration occurs at the convergence of diverse metabolic pathways. In the retina, a common underlying mechanism involves mitochondrial dysfunction since photoreceptor homeostasis and survival are highly susceptible to altered aerobic energy metabolism. We sought to develop an assay to directly measure oxygen consumption in intact retina with the goal of identifying...

BACKGROUND AND AIMS: Assessment of respiration is important in medicine and physical therapy. As respiration is multifaceted, we need several specific examination methods. The purpose of this study was to develop a method for examination of visible respiratory movements, by extracting from two examinations the items with best ability to discriminate among healthy controls, patients with pain di...

Soil respiration (RS) represents a large terrestrial source of CO2 to the atmosphere. Global change drivers such as climate warming and nitrogen deposition are expected to alter the terrestrial carbon cycle with likely consequences for RS and its components, autotrophic (RA) and heterotrophic respiration (RH). Here we investigate the impacts of a 3°C soil warming treatment and a 50 kg ha(-1) y(...

The mechanisms by which noradrenaline, lipolytic agents and long-chain fatty acids stimulate glucose transport were investigated in rat brown adipocytes. Glucose transport was evaluated with tracer D-[U-14C]glucose and cell respiration was measured polarographically. Noradrenaline increased basal oxygen consumption (8-10-fold) and glucose transport (4-5-fold) in a dose-dependent manner, with a ...
