Over the years chromatography has gained an enviable position in analytical laboratories. You have been introduced to simple concepts on how to read a chromatogram.
It is formed by two outer hyperechogenic lines that represent the junction between the basal endometrium and the myometrium; two hypoechoic bands that are the functional layer of the endometrium; and, finally, a central hyperechogenic line, the lumen of the cavity. The literature suggests that ...
Protein and energy Protein and energy are the first nutritional require- ments that should be considered when formulating a diet because they represent the most expensive diet- ary components, but also because of their impact on the productive and reproductive performance of flocks for meat or egg...
The underlying assumption is that an invading species will benefit in a community where it does not encounter intense competition for resources (Alpert et al. 2000). System context In the case of spatially isolated habitats, the breaking of geographic barriers is of major importance for the ...
Hyperexpression of classical HLA class I (HLA-I) molecules in insulin-containing islets has become a widely accepted hallmark of type 1 diabetes pathology. In comparison, relatively little is known about the expression, function and role of non-classical subtypes of HLA-I. This review focuses on...
He received his MD (summa cum laude) in Experimental Ophthalmology with Ted Sharpe (University of Freiburg) and his PhD in Biochemistry with Ed Thompson (University College London). He trained as a neurologist in France (Lyon), Germany (Munich), and the UK (London). He now works as ...
Data on the biological effects of MP in freshwater species is completely lacking. The accumulation of other freshwater contaminants on MP is of special interest because ingestion might increase the chemical exposure. Again, data is unavailable on this important issue. Conclusions MP represent freshwater...
research is to better understand how different bacterial compounds and products of bacterial metabolic activity represent important components for the crosstalk between the host and its microbiota. Regarding the bacterial compounds that are recognized as signaling by the host, including for instance the ...
. They are relatives of retrotransposons and may represent an evolutionary link between the RNA ribozymes and the transition to DNA before a protein RT evolved. The “retroelement hypothesis” suggests that group II ribozymes differentiated into retroelements [57,64]. One can still find this link...
