A living organism must be studied from two distinct aspects. One of these is the causal-analytic aspect which is so fruitfully applicable to ontogeny. The other is the historical descriptive aspect which is unravelling lines of phylogeny with ever-increasing precision. Each of these aspects may ...
Evolution as we currently observe it is predominantly the result of what we call the 'horizontal transfer of information'. This phenomenon consists in the transfer of genetic information between one type of organism and another. The independently pre-evolved information of different types of organisms...
Because of its rapid proliferation, unique nuclear dualism, extensive membrane structure and rapid reaction to external exposure, Tetrahymena serves as a useful model organism for the investigation of some exogenous toxic substances. Studies have found that the fatty acid composition of Tetrahymena ...
predominantly clonal mode of reproduction of this diploid and largely heterozygous organism.11–13 Examples of phenotypic variation across C. albicans isolates have been studied most extensively in the context of antifungal drug resistance.24,25 Differences between natural C. albicans isolates that affect...
Post-translational changes in the redox state of cysteine residues can rapidly and reversibly alter protein functions, thereby modulating biological processes. The nematode C. elegans is an ideal model organism for studying cysteine-mediated redox signaling at a network level. Here we present a compreh...
At the level of the whole organism many environmental, microbiotal and genetic influences determine the quality of the T-cell dependent antibody response (Fig. 1). At cellular level however it relies on tightly regulated interactions between CD4+ T cells and B cells, supported by cells from ...
Atmospheric nitrogen deposition may affect the biodeterioration process of stone monuments through direct and indirect pathways, but relevant studies are lacking. Therefore, taking the biologically colonized rocks around the Leshan Giant Buddha (World Heritage - Mixed Property) as the research objects, we...
(Leclercq et al., 2014), 3) the appearance of increased Coprococcus, a pro-inflammatory bacteria associated with western HFD which increases in CHB and LC but decreases in abundance in HCC (Pedersen et al., 2019), and 4) the decrease in Roseburia, an organism that cross-feeds other ...
E. coliis an ideal model organism due to its rapid growth in pure nutrient media and the availability of many genetic tools to study it. Theodor Escherich, the German pediatrician, isolatedBacterium colifrom the feces of healthy individuals in 1885; it was renamedBacillus coliand eventuallyE. ...
(DrLIN41) sequences as queries, against the non-redundant protein sequence database. This led to the identification of a large group of 3762 closely related sequences. Partial sequences, highly identical sequences from the same organism and smaller isoforms were removed. Based on a preliminary ...
