Early Phosphate Burst of Heart Myosins. Phylogenic Variations

Analysis of variations, structures, and phylogenic characteristics of bovine leukocyte antigen DRB3 exon2

Bovine leukocyte antigen (BoLA) DRB3 is a highly polymorphic gene in major histocompatibility complex(MHC) class II that plays a central role in immune responses and production factors. As of yet, molecular andevolutionary characteristics of BoLA-DRB3.2* have not been as fully understood as human and mouse.Therefore, we attempted to analyze variability and phylogeny of BoLA-DRB3.2* and illustra...

Sigmund Freud on phylogenic memory

It is a widespread misconception that Sigmund Freud talks of phylogenic heritage only in his late work Der Mann Moses und die monotheistische Religion [1937], where he deals with collective Jewish identity. Striking remarks can already be found in Das Ich und das Es [1923] (which starts his second topography), but the idea already surfaces during the period of his first topography in Das Unbewu...

Phylogenic Reconstruction Then and Now

Gamma-Ray Burst Early Afterglows

The successful launch and operation of NASA’s Swift Gamma-Ray Burst Explorer open a new era for the multi-wavelength study of the very early afterglow phase of gamma-ray bursts (GRBs). GRB early afterglow information is essential to explore the unknown physical composition of GRB jets, the link between the prompt γ-ray emission and the afterglow emission, the GRB central engine activity, as wel...

Multiplying myosins.

M yosins are a diverse family of actin-based molecular motors that appeared early in eukaryotic evolution. Just how early, and how diverse, has begun to become clear from work that appears in this issue of PNAS (1) and recent work from Nature (2). For most of its existence, the term ‘‘myosin’’ applied only to the actinactivated ATPase that forms the bipolar thick filaments of muscle and the cyt...
