The stable isotopic compositions of nitrogen and carbon in animal tissues reflect diet. However, factors other than diet can also affect these stable isotope ratios, leading to misinterpretations of diet composition. To test the hypothesis that variation in metabolic rate alters the isotopic compositions of tissues, deer mice (Peromyscus maniculatus (Wagner, 1845)) were kept at three temperatur...

Previous microarray analyses of RNAs from 8-cell (8C) human embryos revealed a lack of cell cycle checkpoints and overexpression of core circadian oscillators and cell cycle drivers relative to pluripotent human stem cells [human embryonic stem cells/induced pluripotent stem (hES/iPS)] and fibroblasts, suggesting growth factor independence during early cleavage stages. To explore this possibili...

Recently 10 T-cell lines were established from patients with adult T-cell leukemia (ATL). During establishment of these cell lines, it was found that when T-cell lines expressing the ATL-associated retroviral antigen were cocultivated with 8C cat cells, multinucleated syncytia were formed. Retroviral antigen-negative T-cell lines did not induce syncytia. Peripheral blood lymphocytes obtained fr...

Water is the most abundant molecular compound on Earth: it is omnipresent and essential for life. Water is a very stable compound because of its high formation enthalpy of 286 kJmol , and thus the splitting of water into dihydrogen and dioxygen is a high-energy process—the thermal splitting of water requires temperatures above 2500 8C, and is still incomplete. Although the electrochemical split...

The present work was aimed at measuring intramuscular oxygen consumption ( ) as a function of temperature (T), Ȯ2 in human forearm, during rest and aerobic isometric exercise (4% of the maximal voluntary contraction, MVC). Based upon results from in vitro experiments performed on isolated mitochondria of animal species, it was hypothesised that, during isometric exercise, the -T curve should di...

Activation and safety analyses were performed for the ARIES-ST design. The ARIES-ST power plant includes a water-cooled copper centerpost. The first wall and shield are made of low activation ferritic steel and cooled with helium. The blanket is also made of ferritic steel with SiC inserts and Li17Pb83 breeder. The divertor plate is made of low activation ferritic steel and uses a tungsten brus...

Particulate organic matter for lipid analyses was collected from specific water depths by in situ filtration of large volumes (,1,000 l) of water through 292-mm diameter precombusted (at 450 8C) glass fibre filters (GFF; nominal pore size 0.7 mm) with in situ pumps. Because filtration through 0.7-mm pore-size filters could lead to an undersampling of anammox cells, the calculated ladderane lipi...
