We show that bigger cells with greater growth and CO2 production rates and lower mass-to-volume ratio were selected over time in the LTEE. These results are consistent with the IDC hypothesis. This novel hypothesis offers a promising approach for understanding the evolutionary constraints on cell ...
relativity has been tested many times, so it is generally accepted as true, but there could be an instance, which has not been encountered, where it is not true. For example, a scientist can form a hypothesis that a
To test the predictions of this hypothesis for the elements C, H, N and O, we designed a precise (standard error 卤0.05%) experiment that measures the parameters of bacterial in minimal media with varying isotopic composition. A number of predicted resonance conditions were tested, with ...
From these systems arose an improved understanding of tumor growth characteristics, a foundation for the key principles of chemotherapy, and eventually, a recognition of the importance of dose scheduling. Specifically, the Norton-Simon hypothesis of tumor kinetics was an important advance in the ...
With respect to oxidative damage and its targets, growth-arrested bacterial cells show some ofthe same signs of senescence as aging insects, worms and mammals. In addition, the fact that the life span of growth-arrested Escherichia coli cells is greatly extended by limiting oxygen availability sug...
Evidence for the stress-linked immunocompetence handicap hypothesis in human male faces Secondary sexual traits that develop under the action of testosterone, such as masculine human male facial characteristics, have been proposed to signal th...

By integrating diverse types of experimental data into a simple biophysical model, we give evidence that this onset is the result of the membrane real estate hypothesis: Fast growth drives cells to be bigger, reducing their surface-to-volume ratios. This decreases the membrane area available for ...
1. Bacterial endotoxin causes a loss of thymic lymphocytes and a change in thymic morphology regardless of the age or stage of development of the mouse. 2. Injection of endotoxin into neonatal mice every 3 days causes a temporarily stunted growth rate, as manifested by slower gain in total ...

66 Atomoxetine is a norepinephrine reuptake inhibitor (NRI) clinically used for the treatment of MDD. After systemic inflammatory attack with bacterial lipopolysaccharide (LPS), atomoxetine can decrease neuroinflammation in the rat cerebral cortex.67 The bioavailability of 5-HT and NE are increased by ...
