The distal human intestine represents an anaerobic bioreactor programmed with an enormous
population of bacteria, dominated by relatively few divisions that are highly diverse at the …

microbiome, is a reflection of evolutionary selection pressures acting at the level of the host …

BACKGROUND A frequent complication of anticancer treatment, oral and gastrointestinal (GI)
mucositis, threatens the effectiveness of therapy because it leads to dose reductions, …

The genesis of new cells, including neurons, in the adult human brain has not yet been
demonstrated. This study was undertaken to investigate whether neurogenesis occurs in the …

We announce the release of an advanced version of the Molecular Evolutionary Genetics
Analysis (MEGA) software, which currently contains facilities for building sequence alignments, …

Comparative analysis of molecular sequence data is essential for reconstructing the evolutionary
histories of species and inferring the nature and extent of selective forces shaping the …

Sorghum, an African grass related to sugar cane and maize, is grown for food, feed, fibre

We have measured the inclusive b→ s γ branching ratio to be (2.32±0.57±0.35)× 10− 4,
where the first error is statistical and the second is systematic. Upper and lower limits on the …

(3) According to Drake andRitter, 4 the surface area of fritted glass, ultrafine porosity, is 0.69
m. 2/g. Since our fritted glass disk weighed 3.3 g., it presumably had a surface area of 2.4 X …
