Molecular biology and riddle of cancer: the ‘Tom & Jerry’ show
(Springer Milan, 2011)
From the conventional Bird’s eye, cancer initiation and metastasis are generally intended to be understood beneath the light of classical clonal genetic, epigenetic and cancer stem cell model. But inspite decades of ...
The Allometry of Prey Preferences
The distribution of weak and strong non-linear feeding interactions (i.e., functional responses) across the links of complex food webs is critically important for their stability. While empirical advances have unravelled ...
Molecular Evidence for the Wide Distribution of Two Lineages of Terrestrial Green Algae (Chlorophyta) over Tropics to Temperate Zone
Phylogenetic analyses of 18S rDNA sequences from environmental clones and culture strains revealed a widespread distribution of two subaerial green algal lineages, Jenufa and Xylochloris, recently described from rainforests ...
Gender in medical ethics: re-examining the conceptual basis of empirical research.
BMP signals and the transcriptional repressor BLIMP1 during germline segregation in the mammalian embryo
Molecular factors and tissue compartments involved in the foundation of the mammalian germline have been mainly described in the mouse so far. To find mechanisms applicable to mammals in general, we analyzed temporal and ...
Unsuspected diversity of Niphargus amphipods in the chemoautotrophic cave ecosystem of Frasassi, central Italy
Background The sulfide-rich Frasassi caves in central Italy contain a rare example of a freshwater ecosystem supported entirely by chemoautotrophy. Niphargus ictus, the sole amphipod species previously reported from this ...
Observations on the population structure and behaviour of two differently managed populations of the greater kudu (Tragelaphus strepsiceros, Pallas 1766) in Namibia
Observations were made on two populations of the greater kudu (Tragelaphus strepsiceros) in Namibia to investigate the influence of differing management strategies (trophy hunting vs. venison production) on the population ...
Minor changes in orthopteran assemblages of Central European protected dry grasslands during the last 40 years
(Springer Netherlands, 2011)
During the past 50 years development of farming practices caused tremendous changes in European agricultural landscapes and many insect species became increasingly restricted to protected areas. Yet little is known about ...
Effects of anionic polyacrylamide on maize growth: a short term 14C labeling study
(Springer Netherlands, 2011)
Various anionic polyacrylamide polymers (PAMs) are frequently used to improve soil properties and reduce erosion. However, the effects of their application on plant growth remain unclear.Aggregate-free loess with high water ...
Comparing sequences without using alignments: application to HIV/SIV subtyping
Background: In general, the construction of trees is based on sequence alignments. This procedure, however, leads to loss of information when parts of sequence alignments (for instance ambiguous regions) are deleted before ...
